Description

  The present invention relates to an electronic component mounting apparatus and an electronic component mounting method in which an electronic component is held and moved by a nozzle and mounted on a substrate.

  An electronic component mounting apparatus for mounting an electronic component on a substrate has a head including a nozzle, holds the electronic component with the nozzle, and mounts the electronic component on the substrate. The electronic component mounting device picks up the components in the electronic component supply device by moving the head nozzle in a direction perpendicular to the surface of the substrate, and then moves the head relatively in a direction parallel to the surface of the substrate. When the picked-up component arrives at the mounting position, the picked electronic component is mounted on the substrate by moving the nozzle of the head in a direction orthogonal to the surface of the substrate and bringing it closer to the substrate.

  Here, as an electronic component mounted on a substrate, there is a lead-type electronic component including a main body and leads connected to the main body, in addition to the mounted electronic component mounted on the substrate. In this case, the lead type electronic component is mounted by inserting a lead into a hole formed in the substrate. Further, in this case, an electronic component that is mounted on the substrate without being inserted into the insertion hole (substrate hole), for example, SOP, QFP, and the like is a mountable electronic component. As an electronic component mounting apparatus for mounting a lead type electronic component on a substrate, for example, there are apparatuses described in Patent Documents 1 and 2. Patent Document 1 describes an electronic component mounting machine including a component mounting machine that mounts both a mountable electronic component that is sucked by a suction head and a lead-type electronic component that is clamped after inserting a substrate by a sandwiching head. Patent Document 2 describes an electronic component mounting apparatus in which a mounting head for mounting a mounting type electronic component and an insertion head for mounting a lead type electronic component are integrally formed.

  Next, the feed unit will be described with reference to FIGS. 18 to 21 in addition to FIGS. Here, FIG. 18 is an explanatory diagram showing a schematic configuration of a feed unit of the electronic component supply apparatus. FIG. 19 is an explanatory diagram showing a schematic configuration of the tip support portion of the feed unit. FIG. 20 is an explanatory diagram showing a schematic configuration of a tape feeding claw unit of the feed unit. FIG. 21 is an explanatory diagram for explaining the operation of the feed unit. The feed unit 114 is a mechanism that transports the electronic component holding tape, that is, moves the electronic component holding tape guided along the guide groove 120. The feed unit 114 includes a support part 142, a drive part 144, a tip support part 146, and a tape feed claw unit 148. In the present embodiment, the tip support portion 146 and the tape feed claw unit 148 serve as a position adjustment mechanism that adjusts the relative position between the tape feed claw unit 148 and the housing 110.

  The support part 142 is a member fixed to the housing 110 and supports the drive part 144. The drive unit 144 includes a fixed unit 144a and a movable unit 144b. The drive unit 144 is an air cylinder that expands and contracts a portion exposed from the fixed unit 144a of the movable unit 144b by air pressure. The drive unit 144 reciprocates the tip of the movable unit 144b in the direction in which the linear portion of the guide groove 120 extends in a predetermined distance range corresponding to at least the feed pitch. That is, the drive unit 144 reciprocates the tip of the movable unit 144b by a distance corresponding to at least the tape feed pitch (pitch P of the holes 78). The tip support portion 146 is fixed to the tip of the movable portion 144 b of the drive portion 144. The tip support portion 146 reciprocates as a unit when the movable portion 144b reciprocates. Further, as shown in FIG. 19, the tip support portion 146 is a surface on the upper side in the vertical direction, and includes four screw holes of screw holes 149 a, 149 b, 149 c, and 149 d in a portion connected to the tape feeding claw unit 148. The four screw holes 149a, 149b, 149c, and 149d are formed at four positions with different positions in the tape feeding direction. Here, in the tip support portion 146, the distance between the screw hole 149a and the screw hole 149b is half the pitch P of the holes 78 of the tape body 72 described above. That is, the screw hole 149a and the screw hole 149b are formed at positions shifted by a half pitch of the arrangement interval of the holes 78. Further, in the tip support portion 146, the distance between the screw hole 149c and the screw hole 149d is half the pitch P of the holes 78 of the tape body 72 described above. That is, the screw hole 149c and the screw hole 149d are formed at positions shifted by a half pitch of the arrangement interval of the holes 78.

  The tape feeding claw unit 148 is fixed to the tip support portion 146. The tape feed claw unit 148 has a mounting base 150, a feed claw 152, a pin 154, and a spring 156. The mounting base 150 is a base that supports the feed claws 152, the pins 154, and the springs 156. The mounting base 150 has a bent plate shape whose cross section perpendicular to the tape feeding direction is L-shaped, and a part on the upper side in the vertical direction is exposed from the housing 110. The mounting base 150 is provided with a grip 158 that can be held by an operator at an exposed portion. The operator can move the tape feeding claw unit 148 in the tape feeding direction by holding and holding the grip portion 158 as necessary. The mounting base 150 is a member that contacts the tip support portion 146 and is fixed to the tip support portion 146 by two fixing screws 159. Here, in the mounting base 150, the distance between the holes into which the two fixing screws 159 are inserted is the same as the distance between the screw holes 149a and 149c and the distance between the screw holes 149b and 149d. That is, the tip support portion 146 has a plurality of combinations of screw holes having the same arrangement pitch of the fixing screws (screws) 159 inserted into the mounting base 150 of the tape feeding claw unit 148 at different positions in the tape feeding direction. Accordingly, the mounting base 150 can shift the relative position between the mounting base 150 and the tip support portion 146 by a half pitch by switching the screw hole into which the fixing screw 159 is inserted.

  The feed claw 152 is a member provided with a convex portion 152a protruding at one end of a rod-shaped member. The feeding claw 152 is disposed at a position facing the hole of the tape main body 72 of the electronic component holding tape (hereinafter also simply referred to as “tape”) 70, and the convex portion 152a is downstream in the feeding direction in the tape feeding direction. The surface 152b (front side in the feed direction) is a surface orthogonal to the feed direction, and the surface 152c on the upstream side in the feed direction (back side in the feed direction) in the tape feed direction is a surface inclined with respect to the surface perpendicular to the feed direction. The width in the feed direction becomes narrower as the tape 70 is approached. When the feed claw 152 has a hole 78 at a position facing the convex portion 152a, the convex portion 152a is inserted into the hole 78 as shown in FIG. The pin 154 supports the end portion of the feed claw 152 on the side where the convex portion 152a is not formed so as to be rotatable in a direction parallel to the paper surface. One end of the spring 156 is fixed to the projecting surface 150 a of the mounting base 150, and the other end is fixed to the feed claw 152. The spring 156 presses the feed claw 152 against the tape side when the convex portion 152a of the feed claw 152 faces a portion other than the hole 78.

  Next, the tape feeding operation of the feed unit 114 will be described with reference to FIG. In the example shown in FIG. 21 (steps S1 to S4), the hole formed in the tape main body 72 is provided on the downstream side in the tape feeding direction (first supplied to the casing 110 and first discharged from the casing 110). 78, 78a, 78b, 78c in order from the side). In step S <b> 1, the convex portion 152 a of the feed claw 152 is inserted into the hole 78 a of the tape main body 72. As shown in step S1, the feed unit 114 drives the drive unit 144 in a state where the convex portion 152a is inserted into the hole 78a, and feeds one pitch of the hole of the tape main body 72 in the tape feeding direction. 148 is moved.

  When the feed unit 114 feeds the tape feed claw unit 148 in the tape feed direction in the state of step S1, the hole 78a is pushed in the tape feed direction by the surface orthogonal to the feed direction of the convex portion 152a, as shown in step S2. In addition, both the tape feeding claw unit 148 and the tape main body 72 are moved in the tape feeding direction. The feed unit 114 moves the electronic component of the tape to the holding position by moving the tape main body 72 in the tape feeding direction.

  When the movement in the tape feeding direction to the tape feeding claw unit 148 is completed (step S2), the feed unit 114 stands by with the electronic component at the tip held by the tape main body 72 as a holding position. At this time, the electronic component in the holding position (holding region) is clamped on the electronic component main body and the lead is cut by the cutter as described later. Next, when a predetermined process is executed on the electronic component mounting apparatus side, a drive command is transmitted. For example, when the electronic component at the holding position held by the tape is picked up by the suction nozzle of the head or gripped by the gripping nozzle, a clamp release command is sent to the electronic component supply device, and the electronic component supply device clamps the electronic component. Is released. Thereafter, when the electronic component held by the nozzle is pulled up by the nozzle rising, a drive command is transmitted to the feed unit 114. When the drive command is transmitted, the feed unit 114 drives the drive unit 144 to move the tape feed claw unit 148 by one pitch of the hole of the tape main body 72 in the direction opposite to the tape feed direction. When the feed unit 114 feeds the tape feeding claw unit 148 to the side opposite to the tape feeding direction in the state of step S2, the inclined surface of the convex portion 152a is in contact with the hole 78a, and the convex portion 152a is moved along the inclination. It moves in the direction to escape from the hole 78a. Thereby, as shown in step S3, in the feed unit 114, the convex portion 152a is removed from the hole 78a (step S3), the tape does not move, and the tape feed claw unit 148 moves to the opposite side to the tape feed direction. Moving.

  Thereafter, when the feed unit 114 moves the tape feed claw unit 148 by one pitch of the hole of the tape main body 72 from the state shown in step S2 in the direction opposite to the tape feed direction, as shown in step S4, the convexity is obtained. The portion 152a is inserted into the hole 78b that is one pitch upstream from the hole 78a. At this time, since the feeding claw 152 is pushed in the direction of the hole 78b by the spring 156, the convex portion 152a is accurately inserted into the hole 78b. Thereafter, the drive unit 144 is immediately driven in the tape feeding direction, and the next electronic component held by the tape body 72 is transferred to the holding position.

  In this way, the feed unit 114 causes the tape feeding claw unit 148 to reciprocate in the feeding direction by one pitch of the hole of the tape main body 72 by the driving unit 144, thereby sequentially moving the tape by one pitch in the feeding direction. Can do.

  Next, the cutting unit will be described with reference to FIGS. 22 to 24 in addition to FIGS. FIG. 22 is an explanatory diagram showing a schematic configuration of a cut unit of the electronic component supply apparatus. FIG. 23 is an explanatory diagram showing a schematic configuration of a cut unit of the electronic component supply apparatus. FIG. 24 is an explanatory diagram showing a schematic configuration of a cut unit of the electronic component supply apparatus. The cut unit 116 cuts the lead of the electronic component held on the electronic component holding tape. Further, the cut unit 116 clamps, that is, holds the electronic component whose lead has been cut until the electronic component is sucked (held) by the nozzle. The cut unit 116 includes a support part 162, a drive part 164, a transmission part 166, a cutting part 168, and a cover 169.

  The support part 162 is a member fixed to the housing 110 and supports the drive part 164 and the transmission part 166. Further, the support part 162 supports the cutting part 168 via the transmission part 166. The drive unit 164 includes a fixed unit 164a and a movable unit 164b. The drive unit 164 is an air cylinder that expands and contracts a portion exposed from the fixed unit 164a of the movable unit 164b by air pressure. The drive unit 164 reciprocates the tip of the movable unit 164b within a predetermined distance range in the direction in which the linear portion of the guide groove 120 extends. The transmission unit 166 is a transmission mechanism that transmits power generated by the reciprocating movement of the movable unit 164b to the cutting unit 168. The transmission unit 166 converts the reciprocating movement of the movable unit 164b in the tape feeding direction into a movement in a direction orthogonal to the tape feeding direction, and moves the cutting unit 168 in a direction orthogonal to the tape feeding direction. The transmitting portion 166 moves in a direction in which the tip end portion 166a and the tip end portion 166b arranged with the tape passing region therebetween approach each other or away from each other, that is, a direction indicated by an arrow 170. When the transmission part 166 of this embodiment moves in the direction in which the movable part 164b of the drive part 164 extends, the tip part 166a and the tip part 166b move in a direction approaching each other. When the movable part 164b of the driving part 164 moves in the contracting direction, the transmission part 166 moves the tip part 166a and the tip part 166b away from each other.

  The cutting part 168 is arranged in the holding area, holds the electronic component main body arranged in the holding area, then cuts the lead of the electronic component between the main body and the tape main body, and then holds the electronic component Maintain the state. The cutting part 168 has a first blade part 168a and a second blade part 168b. The cutting part 168 is disposed at a position where the first blade part 168a and the second blade part 168b face each other. The tape is arranged between the first blade portion 168a and the second blade portion 168b, and the lead of the electronic component held on the tape is sandwiched between the first blade portion 168a and the second blade portion 168b. Pass through the position. As shown in FIG. 24, the first blade portion 168a is connected to the tip portion 166a of the transmission portion 166, and when the tip portion 166a moves to the second blade portion 168b side, the second blade portion 168b together with the tip portion 166a. Move to the side. As shown in FIG. 24, the second blade portion 168b is connected to the tip portion 166b of the transmission portion 166, and when the tip portion 166b moves to the first blade portion 168a side, the first blade portion 168a together with the tip portion 166b. Move to the side. The first blade portion 168a is connected to the tip portion 166a via a spring, and is pressed against the second blade portion 168b by the tip portion 166a.

  The cover 169 is a member that is fixed to the housing 110. The cover 169 is disposed around the first blade portion 168a, and the surface that contacts the second blade portion 168b of the first blade portion 168a is an opening. Further, the cover 169 is in contact with the distal end portion 166a via a spring, and pushes the distal end portion 166a away from the second blade portion 168b. Thereby, when the front-end | tip part 166a is not pressed on the 2nd blade part 168b side, the force of the direction away from the 2nd blade part 68b can be provided to the 1st blade part 168a.

  The cut unit 116 is configured as described above, and the drive unit 164 brings the first blade portion 168a on the movable side of the cutting portion 168 closer to the second blade portion 168b on the fixed side, so that the electronic component body side The first blade portion 168a on the movable side of the cutting portion 168 and the second blade portion 168b on the fixed side are brought close to each other and brought into contact with each other, so that the first blade portion 168a on the movable side and the first blade portion 168a on the fixed side are brought into contact with each other. The lead disposed between the two blade portions 168b can be cut. Further, the cut unit 116 maintains the state in which the first blade portion 168a and the second blade portion 168b are in contact with each other after cutting the leads, so that the side of the main body of the electronic component separated from the tape main body can be removed. Can be supported. That is, the electronic component separated from the tape body can be clamped by cutting the lead. The cut unit 116 may have a mechanism for cutting the lead of the electronic component and a mechanism for clamping (supporting) the cut electronic component (the main body of the electronic component) as separate mechanisms.

  Here, the cutting position of the lead cut by the cutting unit 116 will be described. In a conventional mounting apparatus having a lead-type electronic component dedicated head for inserting a substrate, the lead is cut near the tip of the lead close to the tape for fixing the lead, and a very long lead is inserted into the substrate. This is because the conventional mounting apparatus has a lead cutting part and a lead gripping part on the head side, and the lead gripping part grips the root of the lead and then cuts the lower part (temporary cutting). This is because it becomes longer. In addition, since the conventional mounting apparatus guides and inserts into the guide pin when inserting the lead into the insertion hole, even if the lead is long, it does not interfere with the board insertion. In addition, the conventional mounting apparatus is used for temporary cutting to separate the leads from the component tape in order to perform post-processing by a lead bending apparatus that cuts the leads to the required length (main cutting) and folds them on the back surface of the substrate. Because it was necessary to keep it long.

  On the other hand, the cut unit 116 is configured such that the lead cutting length of the radial lead type electronic component is equal to the thickness of the substrate or the lead protruding on the back side of the substrate does not cause a solder failure, and The predetermined length is a length corresponding to the thickness. The predetermined length is, for example, substantially the same length as the insertion hole of the substrate. More specifically, the length is 0 mm or more and 3 mm or less with respect to the length of the insertion hole of the substrate. Thus, the following effects can be obtained by using a configuration in which a component is not cut temporarily with a head as in the prior art, but is cut into a predetermined length from the beginning with a component supply device.

  The electronic component mounting apparatus 10 can improve the stability of the lead interval when the main body of the electronic component at the holding position of the component supply apparatus 100 is held by the nozzle by the cut unit 116 cutting the leads short. It is possible to increase the number of parts in which the lead can be inserted into the insertion hole, and it can be mounted very efficiently and with high accuracy.

  Also, in the conventional mounting apparatus, when a long lead is inserted into the solder paste previously filled or applied in the insertion hole, most of the solder paste is pushed out to the lead tip side, and the melted solder during reflow soldering is inserted into the insertion hole. It may not be able to rise in the narrow gap between the lead and the lead, and soldering may be defective. On the other hand, the electronic component mounting apparatus 10 can perform the best soldering in which the solder melted in the gap rises and the solder is filled with no gap when the cut unit 116 cuts the lead short. Furthermore, by mounting the mountable electronic component on the solder paste applied to the upper surface of the substrate, the lead type electronic component and the mountable electronic component can be simultaneously performed by a single reflow soldering process. In other words, when a lead that is too long for the solder paste previously filled or applied in the insertion hole is inserted, most of the solder paste is pushed to the lead tip side, and the solder melted during reflow soldering cannot rise to the substrate, That is, the solder may not reach the substrate and soldering may be defective. On the other hand, in the electronic component mounting apparatus having the above configuration, when the lead is cut into the predetermined length, a part of the solder pushed out of the insertion hole by the lead inserted through the insertion hole is melted. It rises to the back surface of the substrate and can be soldered to the electrode on the back surface of the substrate. Furthermore, when there is an electrode inside the insertion hole (substrate hole), the solder can be raised and soldered into the gap between the lead and the electrode inside the substrate. In this way, mechanical and electrical soldering can be performed.

  In addition, by setting the predetermined length to be equal to the thickness of the substrate, it is possible to prevent the leads from protruding from the substrate (back surface of the substrate) even when the radial lead type electronic component is mounted on the substrate. Further, by setting the predetermined length to such a length that the lead protruding to the back side of the substrate does not cause a solder failure, the lead can be suitably fixed to the insertion hole of the substrate by reflow processing even if the lead is shortened.

  The air pressure adjusting unit 118 adjusts the air pressure of the air cylinder that is the driving unit 144 of the feed unit 114 and the air cylinder that is the driving unit 164 of the cut unit 116, and controls the driving of each unit. Specifically, the air pressure adjusting unit 118 controls the position of the feeding claw 152 by controlling the expansion / contraction, that is, the position of the movable unit 144 b of the driving unit 144. The air pressure adjusting unit 118 controls the expansion / contraction, that is, the position of the movable unit 164b of the driving unit 164, and controls the positions of the first blade unit 168a and the second blade unit 168b of the cutting unit 168. The air pressure adjusting unit 118 controls the air pressure of each unit based on the control by the component supply control unit 64.

  The component supply apparatus 100 is configured as described above. The component supply device 100 is provided with a plurality of positions in the tape feed direction for attaching the mounting base 150 of the tape feed claw unit 148 to the tip support part 146, and can switch the position where the tape feed claw unit 148 is installed with respect to the tip support part 146. By adopting the configuration, it is possible to cope with a plurality of electronic component holding tapes having different relative positions between the hole of the tape body and the electronic component without exchanging the components. That is, the component supply apparatus 100 switches the position at which the mounting base 150 of the tape feed claw unit 148 is attached to the tip support portion 146 based on the relative position between the hole of the tape body of the electronic component holding tape to be loaded and the electronic component. Thus, in any electronic component holding tape, the electronic component can be moved to the holding position.

  Specifically, the feed unit 114 is in a state in which the movable portion 144b of the driving portion 144 is extended most in the range of reciprocating movement by changing the position where the mounting base 150 of the tape feeding claw unit 148 is attached to the tip support portion 146. The position of the convex part 152a of the feed claw 152 in the position to become can be changed. As a result, the feed unit 114 has various positions where the hole of the tape body is located when the movable portion 144b of the drive portion 144 is set to the position where the movable portion 144b is most extended in the range of reciprocating movement (feed completion position, holding position). Can be in the position. As a result, even if the feed unit 114 is an electronic component holding tape having a different arrangement position of the electronic component with respect to the position of the hole, the electronic component is not moved when the movable portion 144b is in the most extended state in the reciprocating range. It can be arranged in a holding position.

  Moreover, it is preferable that the component supply apparatus 100 makes the distance of the reciprocating movement of the movable part 144b of the feed unit 114 longer than the pitch of the holes in the tape main body and shorter than twice the pitch. Thereby, the component supply apparatus 100 can reliably insert the convex portion 152a of the feeding claw 152 into the hole of the next pitch, and can feed the tape by one pitch by one reciprocating movement of the feeding claw 152. . Further, when there are a plurality of types of hole pitches of the tape to be conveyed, the component supply device 100 sets the distance of the reciprocating movement of the movable portion 144b of the feed unit 114 to be longer than the hole having the longest hole pitch. The pitch is preferably shorter than twice the pitch of the shortest tape. As a result, the component supply device 100 can reliably insert the convex portion 152a of the feed claw 152 into the hole of the next pitch regardless of the tape pitch. The tape can be fed by one pitch. That is, the component supply apparatus 100 can feed a plurality of types of tapes one pitch at a time without changing the reciprocating distance or replacing the components.

  Here, in the feed unit 114 of the above embodiment, the position where the tape feeding claw unit 148 is attached to the tip support portion 146 can be selected at two locations, but the number is not limited to this. The feed unit 114 can cope with more types of electronic component holding tapes by increasing the selectable positions where the tape feed claw unit 148 is attached to the tip support part 146. Further, the feed unit 114 may be capable of linearly adjusting the position where the tape feed claw unit 148 is attached to the tip support portion 146. For example, by forming one of the screw holes of the tip support portion 146 or the tape feed claw unit 148 into a long hole shape extending in the tape feed direction, the tip support portion 146 and the tape feed claw unit 148 in the tape feed direction. The relative position may be set to various positions. In this case, it is preferable that the relative position in the tape feeding direction between the tip support portion 146 and the tape feeding claw unit 148 can be adjusted within a range corresponding to one pitch of the hole of the tape. Thereby, the feed unit 114 can arbitrarily adjust the relative position, and fine adjustment of the relative position is also possible.

  Further, the feed unit 114 of the above embodiment uses the front end support portion 146 and the tape feed claw unit 148 as a position adjustment mechanism, and changes the relative position between the front end support portion 146 and the tape feed claw unit 148 to thereby change the tape. A configuration in which the position of the convex portion 152a of the feeding claw 152 can be changed when the feeding is finished, that is, when the movable portion 144b is in the most extended state in the reciprocating movement range (relative between the casing 110 and the tape feeding claw unit 148). However, the position is not limited to this. As the feed unit, various mechanisms capable of adjusting the relative position between the housing and the tape feeding claw unit can be used as the position adjusting mechanism. For example, the component supply device can adjust the relative position of the housing and the feed unit in the tape feeding direction, so that the tape has been fed, that is, the movable portion 144b has been extended most in the reciprocating movement range. It is good also as a structure which can change the position of the convex part 152a of the feeding nail | claw 152 at the time. That is, the feed unit may be provided with a position adjustment mechanism at the connecting portion between the feed unit and the housing.

FIG. 30 is an explanatory diagram for explaining the operation of the cut unit shown in FIG. Note that the cut unit 116 a shown in FIGS. 25 to 30 has the same basic configuration as the cut unit 116. Hereinafter, the points peculiar to the cut unit 116a will be described.

  The cut unit 116a cuts the lead of the electronic component held on the electronic component holding tape. Further, the cut unit 116a clamps, that is, holds the electronic component whose lead has been cut until the electronic component is sucked or gripped (held) by the nozzle 32 (suction nozzle or gripping nozzle). The cut unit 116a includes a support part 162, a drive part 164, a transmission part 172, a cutting part 174, and a cover.

  The transmission unit 172 is a transmission mechanism that transmits power generated by the reciprocating movement of the movable unit 164b to the cutting unit 174. The transmission unit 172 converts the reciprocating movement of the movable unit 164b in the tape feeding direction into a movement in a direction orthogonal to the tape feeding direction, and moves the cutting unit 174 in a direction orthogonal to the tape feeding direction. The transmission unit 172 includes a stator 175 and a mover 176 that are arranged across a tape passage region. The transmission unit 172 moves the first unit 174a connected to the mover 176 of the cutting unit 174 in a direction toward or away from the second unit 174b connected to the stator 175 of the cutting unit 174. That is, as illustrated in FIG. 29, the transmission unit 172 of the present embodiment moves in a direction in which the movable element 176 approaches the stator 175 when the movable part 164 b of the driving unit 164 moves in the extending direction. When the transmission unit 172 moves in a direction in which the movable unit 164b of the driving unit 164 contracts, the movable unit 176 moves in a direction away from the stator 175. As described above, the cut unit 116a is configured such that only one of the two units of the cutting unit 174 moves.

  The cutting unit 174 is disposed in the holding area, and cuts and holds the lead of the electronic component arranged in the holding area between the main body and the tape main body. The cutting unit 174 holds both the main body and the lead of the electronic component 80, then cuts the lead, and maintains the state where the main body and the lead are held even after the lead is cut. The cutting unit 174 includes a first unit 174a and a second unit 174b. The first unit 174a includes a first blade 178a, a first main body holding part 179a, and a first lead holding part 180a. The first blade 178a and the second blade 178b serve as the cutting mechanism 178, and the first main body holding portion 179a and the second main body holding portion 179b serve as the main body holding mechanism 179, and the first lead holding portion 180a and the second lead holding portion 180b. Becomes the lead holding mechanism 180. As shown in FIG. 30, the cutting unit 174 is arranged in the order of the main body holding mechanism 179, the lead holding mechanism 180, and the cutting mechanism 178 from the upper side in the vertical direction.

  Each part of the first unit 174a and each part of the second unit 174b are arranged at positions facing each other. The tape is disposed between the first unit 174a and the second unit 174b, and the lead of the electronic component held on the tape is sandwiched between the cutting mechanism 178 and the lead holding mechanism 180, and the main body of the electronic component is It passes through a position sandwiched between the main body holding mechanisms 179.

  In the cutting part 174, the first unit 174a is supported by the movable element 176, and moves together with the movable element 176 in the direction approaching or moving away from the second unit 174b (the arrow direction in FIG. 30). When the first unit 174a moves in a direction approaching the second unit 174b, the cutting unit 174 has a state in which the main body holding mechanism 179 holds the main body of the electronic component 80 and the lead holding mechanism 180 holds the lead of the electronic component 80. Become. Thereafter, when the first unit 174a moves in a direction closer to the second unit 174b, the cutting unit 174 intersects the first blade 178a and the second blade 178b of the cutting mechanism 178 and cuts the lead. In FIG. 30, the first blade 178a and the second blade 178b appear to overlap, but the first blade 178a and the second blade 178b have different positions in the left-right direction on the paper surface (conveyance). In fact, they are not in contact with each other.

  The cutting unit 116a includes a clamping mechanism (main body holding mechanism 179, lead holding mechanism 180) that holds the electronic component 80 and a cutting mechanism 178 that cuts the lead 84 as one drive unit 164 as a drive source. Move in conjunction. Thereby, the cut unit 116a can perform holding of the electronic component 80 and cutting of the lead with a simple configuration. This also applies to the cut unit 116.

  In addition, the cut unit 116 a can hold the electronic component 80 appropriately after the lead 84 is cut by holding the main body 82 of the electronic component 80 with the main body holding mechanism 179. Thereby, the electronic component 80 after cutting the lead 84 can be appropriately held, and the electronic component 80 can be easily held by the nozzle 32. This also applies to the cut unit 116.

  Further, the cut unit 116a holds the electronic component 80 with a clamp mechanism before cutting the lead 84, and particularly holds the electronic component 80 in a stable position by holding the main body 82 of the electronic component 80. The lead 84 can be cut. Thereby, the lead 84 can be appropriately cut. In addition, the cut unit 116a holds the electronic component 80 with a clamp mechanism before cutting the lead 84, thereby preventing the electronic component 80 that has cut the lead 84 from being removed from the holding position or falling. can do.

  The cut unit 116a holds the lead 84 in addition to the main body 82, so that the position of the lead 84 can be regulated at the time of cutting, and the lead 84 can be cut more appropriately. Also, by holding the main body side lead 84 by the lead holding mechanism 180, deformation of the main body side lead 84 that occurs during cutting can be reduced.

  The cut unit 116a can simplify the mechanism of the apparatus by using one of the transmission portions 172 as a stator 175. Further, the electronic component held by the cut unit 116a can be held in a stable position, and the operation of the head 15 can be simplified. The cut unit 116a preferably includes both the main body holding mechanism 179 and the lead holding mechanism 180, but only one of them may be provided.

  Here, as shown in FIG. 27, the cut unit 116a is fixed by inserting bolts 182 and 185 into elongated holes 181 and 184 formed in the casing 110a and having a longitudinal direction as a longitudinal direction. Thereby, the cut unit 116a can adjust the position of a perpendicular direction. Thereby, the position of the perpendicular direction with respect to the electronic component hold | maintained at the tape moved by the feed unit can be adjusted. Therefore, the cut unit 116a can adjust the vertical position for cutting the lead with respect to the position of the tape, that is, the cutting position for the radial lead type electronic component. As described above, the cut unit 116a can adjust the length of the lead wire after cutting. In this embodiment, the mechanism for adjusting the cutting position for the radial lead type electronic component is a combination of a long hole whose adjustment direction is long and a bolt for fixing the position with respect to the long hole. It is not limited. The electronic component supply device may be a mechanism that can adjust the position of the cutting unit 116a in the Z-axis direction, more specifically, the position of the cutting mechanism in the Z-axis direction with respect to the electronic component holding tape in the holding region.

  Further, the cut unit 116a has a lever 188 exposed outside the housing 110a. The lever 188 is connected to the linear movement portion of the transmission portion 172. Thereby, the cut unit 116a can perform the cutting | disconnection operation | movement of an electronic component by the cutting part 174 by moving the lever 188 to the arrow direction. That is, by moving the lever 188 in the direction of the arrow, the same operation as moving the transmission unit 172 in the linear motion direction by the drive unit 164 can be executed. Thereby, for example, when the position of the cut unit 116a is adjusted, the lead of the electronic component can be cut without driving the drive unit 164 by the control device 20 of the electronic component mounting apparatus 10. Further, the lead of the electronic component can be cut even when air pressure or electric power is not supplied to the drive unit 164.

  Note that the electronic component supply apparatus 100 may include an operation unit for driving the drive unit 164 in the housing 110a. Thereby, the electronic component supply apparatus 100 can execute the cutting operation of the lead of the electronic component by the cut unit 116a without operating the control device 20. In this case, it is necessary to supply driving force (pneumatic pressure or electric power) to the driving unit 164.

  FIG. 31A is an explanatory diagram illustrating a schematic configuration of a holding mechanism of the cut unit. FIG. 31B is an explanatory diagram illustrating a schematic configuration of another example of the holding mechanism of the cut unit. As shown in FIG. 31A, the second main body holding portion 179b of the cut unit 116a is a block including two holes 190 into which bolts to be fixed to the stator 175 of the transmission portion 172 are inserted. The second main body holding portion 179b includes four surfaces that are parallel to the line connecting the two holes 190 and that have different distances from the hole 190. The distance between the first surface 191a and the hole 190 is an arrow 192a. The distance between the second surface 191b and the hole 190 is an arrow 192b. The distance between the third surface 191c and the hole 190 is an arrow 192c. The distance between the fourth surface 191d and the hole 190 is an arrow 192d. The arrows 192a, 192b, 192c, and 192d all have different lengths. The cut unit 116a faces the first main body holding portion 179a by changing the direction of the second main body holding portion 179b (upside down and left / right reverse) when the second main body holding portion 179b is fixed to the stator 175. The surface to be switched can be switched to the first surface 191a, the second surface 191b, the third surface 191c, or the fourth surface 191d. Here, since the position of the bolt that fixes the hole 190 is fixed, the surface that faces the first main body holding portion 179a of the second main body holding portion 179b is switched by switching the surface that faces the first main body holding portion 179a. The distance from the first main body holding portion 179a can be changed.

  Accordingly, the cut unit 116a can change the distance between the second main body holding portion 179b and the first main body holding portion 179a during the lead cutting operation into four types, and the electronic component supplied by the electronic component supply apparatus 100 Depending on the type, the distance between the second main body holding portion 179b and the first main body holding portion 179a can be adjusted as appropriate.

  The second main body holding portion 195 shown in FIG. 31B has an octagonal column shape, and the first main body holding portion 179a is a flat surface. The second main body holding portion 195 has a hole 196 into which a bolt is inserted. The hole 196 is a long hole whose longitudinal direction is the direction orthogonal to the tape transport direction, that is, the direction in which the cut unit moves. The second main body holding portion 195 can adjust the position of the second main body holding portion 195 with respect to the bolt in the operation direction of the cutting portion by adjusting the relative position between the hole 196 and the bolt. In this way, the cut unit uses the second main body holding portion 195, so that the surface facing the first main body holding portion 179 a of the second main body holding portion 195 between the longitudinal distances of the holes 196, The distance from the one main body holding portion 179a can be adjusted. Thereby, a cut unit can respond to the width | variety of the main body of more electronic components. For example, the cutting unit can cut the leads while holding 20 types of lead-type electronic components, and can provide 20 types of lead-type electronic components that can be supplied to the holding position with the leads cut.

FIG. 33 is a perspective view showing a schematic configuration of the feed unit shown in FIG. 32 viewed from another direction. FIG. 34 is a front view showing a schematic configuration of the feed unit shown in FIG. FIG. 35 is a top view showing a schematic configuration of the feed unit shown in FIG. FIG. 36 is a front view showing a schematic configuration of another state of the feed unit shown in FIG. FIG. 37 is a top view showing a schematic configuration of another state of the feed unit shown in FIG. The feed unit 200 shown in FIGS. 32 to 37 changes the position of the convex portion 152a of the feed claw 152 when the tape has been fed, that is, when the movable portion 144b is in the most extended state in the reciprocating movement range. Except for possible configurations, the configuration is basically the same as that of the feed unit 114.

  The feed unit 200 includes a support unit 202, a drive unit 204, a first tip support unit 206, a tape feed claw unit 208, a second tip support unit 209, a return direction tape feed claw unit 210, and an interlocking mechanism 211. And having. The drive unit 204 has the same configuration as the drive unit 144. Further, the first tip support portion 206 and the tape feed claw unit 208 of this embodiment do not have a position adjustment function in the tape feed direction. Further, the tape feeding claw unit 208 does not include a grip portion. Other configurations of the first tip support portion 206 and the tape feed claw unit 208 are the same as those of the tip support portion 146 and the tape feed claw unit 148.

  The support unit 202 is a mechanism that directly or indirectly supports the drive unit 204, the first tip support unit 206, the tape feed claw unit 208, the return direction tape feed claw unit 210, and the interlocking mechanism 211. Yes, and fixed to the housing 110. The support portion 202 includes a support member 222, two protrusions 230, two screws 232, and two screws 236.

  The support member 222 is a plate-like member that faces the surface of the casing 110 having the longest box-shaped area, and faces one surface of the drive unit 204, the first tip support unit 206, and the tape feed claw unit 208. doing. The support member 222 is connected to the fixed portion of the drive unit 204 and supports the fixed portion. Further, the support member 222 is fixed to the housing 110 via the protrusion 230.

  The protrusion 230 is disposed on the surface of the support member 222 opposite to the surface facing the tape feed claw unit 208 and the like. The protrusion 230 protrudes in a direction away from the tape feed claw unit 208 and the like. Two protrusions 230 are arranged at positions separated by a predetermined distance in the tape feeding direction of the support member 222.

  The two screws 232 are respectively screwed into one end of the protrusion 230 (the end on the side in contact with the support member 222). Further, the screws 232 are inserted into elongated holes 222a formed in the support member 222, respectively. The long hole 222a formed in the support member 222 is a hole extending in the tape feeding direction. The elongated hole 222a has a shape in which the screw 232 can move in a range corresponding to one pitch of the tape hole in the tape feeding direction.

  The two screws 236 are screwed to the other end of the protrusion 230, respectively. Further, the screws 236 are inserted into the long holes 212 formed in the casing 110, respectively. A long hole 212 formed in the housing 110 is a hole extending in the tape feeding direction. The long hole 212 has a shape in which the screw 236 can move in the tape feed direction within a range corresponding to one pitch of the tape hole.

  In the feed unit 200, a screw 232 screwed into the protrusion 230 is inserted into the elongated hole 222 a of the support member 222. In the feed unit 200, a combination of the protrusion 230, the screw 232, and the long hole 222 a formed in the support member 222 serves as a position adjustment mechanism. The feed unit 200 can fix the relative position of the feed unit 200 and the housing 110 in the tape feeding direction by fastening the screw 232 and fastening the protrusion 230 and the support member 222. Further, the feed unit 200 can relatively move the elongated hole 222a and the screw 232 by making the screw 232 loose. Thereby, the support member 222 in which the long hole 222a is formed can be relatively moved in the tape feeding direction with respect to the protrusion 230 into which the screw 232 is inserted. The feed unit 200 can move the support unit 222 and the protrusion 230 relative to each other so that the feed unit 200 can move in the tape feeding direction with respect to the housing 110. Thereby, the feed unit 200 can adjust the relative position of the feed unit 200 and the housing 110 in the tape feeding direction by loosening the screws 232, and the feed unit 200 and the housing 110 can be adjusted by tightening the screws 232. The relative position in the tape feeding direction can be fixed.

  In the feed unit 200, a screw 236 screwed into the protrusion 230 is inserted into the elongated hole 212 of the housing 110. In the feed unit 200, a combination of the protrusion 230, the screw 236, and the long hole 212 formed in the housing 110 serves as a position adjustment mechanism. The feed unit 200 can fix the relative position of the feed unit 200 and the housing 110 in the tape feeding direction by fastening the screw 236 and fastening the protrusion 230 and the housing 110. The feed unit 200 can move the elongated hole 212 and the screw 236 relative to each other by loosening the screw 236. As a result, the casing 110 in which the long hole 212 is formed can be moved relative to the protrusion 230 into which the screw 236 is inserted in the tape feeding direction. The feed unit 200 can move the feed unit 200 in the tape feeding direction with respect to the housing 110 by allowing the housing 110 and the protrusion 230 to move relative to each other. Thereby, the feed unit 200 can adjust the relative position of the feed unit 200 and the housing 110 in the tape feeding direction by loosening the screw 236, and the feed unit 200 and the housing 110 can be adjusted by tightening the screw 236. The relative position in the tape feeding direction can be fixed.

  The feed unit 200 is configured such that the entire feed unit 200 and the housing 110 can be moved relative to each other in the tape feeding direction, so that the position of the feeding claw in the tape feeding direction can be easily set without replacing parts. Can be adjusted. Further, the feed unit 200 can move the feed unit 200 with respect to the housing 110 simply by loosening the screw 232 from the outside of the housing 110. Thereby, the position of the feed claw in the tape feed direction can be adjusted more easily. Here, when the operator relatively moves the feed unit 200 and the casing 110 in the tape feeding direction, the operator holds the supporting member 222 and moves the supporting member 222 in the tape feeding direction with respect to the casing 110. It can be moved relative. The operator may hold the protrusion 230 and move it relatively. Further, when the operator loosens the screw 236 and moves the feed unit 200 and the housing 110 relative to each other in the tape feeding direction, the operator also holds the loosened screw 236 and moves the screw 236 with respect to the long hole 212. The unit 200 and the housing 110 can be relatively moved in the tape feeding direction. In this case, it is preferable to make the screw 236 easy to hold.

  Further, the feed unit 200 is preferably a state in which the housing 110 and the protrusion 230 are fixed by the screw 236 when the relative position is moved by a mechanism in which the screw 232 and the elongated hole 222a are combined. Further, the feed unit 200 is preferably a mechanism in which the screw 236 and the long hole 212 are combined, and when the relative position is moved, the support member 222 and the protrusion 230 are preferably fixed by the screw 232.

  The feed unit 200 is provided with two mechanisms as a position adjusting mechanism, a mechanism combining the screw 232 and the elongated hole 222a, and a mechanism combining the screw 236 and the elongated hole 212. Although the relative position of the casing 110 in the tape feeding direction can be adjusted, the present invention is not limited to this. The feed unit 200 may be provided with only a mechanism that combines the screw 232 and the long hole 222a provided in a portion for fixing the protrusion 230 and the support member 222 as a position adjusting mechanism. In addition, the feed unit 200 may be provided with only a mechanism that combines the screw 236 and the long hole 212, which is a portion that fixes the protrusion 230 and the housing 110, as a position adjustment mechanism.

  Further, the feed unit 200 reciprocates the first tip support portion 206 in the tape feeding direction by the drive unit 204, thereby moving the tape feeding claw unit 208 to the position shown in FIGS. 34 and 35, and FIGS. Reciprocally move to the position shown in. Thus, by reciprocating the tape feeding claw unit 208, the tape can be fed one pitch at a time in the tape feeding direction as in the case of the feed unit 114.

  Here, as described above, the feed unit 200 of the present embodiment further includes the second tip support portion 209, the return direction tape feed claw unit 210, and the interlocking mechanism 211. Hereinafter, the second tip support portion 209, the return direction tape feed claw unit 210, and the interlocking mechanism 211 will be described with reference to FIGS. 38 to 43 in addition to FIGS.

FIG. 41 shows a housing 280 for explaining the feed unit 200.

  As shown in FIG. 38 and FIG. 39, the second tip support portion 209 is a plate-like member facing the surface of the casing 110 having the longest elongated box shape area. It faces the other surface of the tape feed claw unit 208. That is, the second tip support portion 209 and the support member 222 are arranged at positions where the drive portion 204, the first tip support portion 206, and the tape feed claw unit 208 are sandwiched. The second tip support part 209 is fixed to the support member 222 via the connecting part 226 and the interlocking mechanism 211. The second tip support part 209 is a mechanism that supports a return direction tape feed claw unit 210 described later, and is connected to the interlocking mechanism 211 by a connecting part 226. The second tip support portion 209 is partially exposed from the casing 110 on the upper side in the vertical direction. That is, the second tip support portion 209 is partially exposed to the outside of the housing 110 from the surface on which the guide groove 120 of the housing 110 is formed. A grip portion 228 is provided on a part of the second tip support portion 209 on the upper side in the vertical direction. Further, the support member 222 and the second tip support portion 209 support the first tip support portion 206 in a state that it can move in the tape feeding direction.

  The connecting part 226 is configured by a bolt, a nut, and the like, and fixes the second tip support part 209 to the interlocking mechanism 211. As described above, the grip portion 228 is provided on a part of the second tip support portion 209 on the upper side in the vertical direction. The grip portion 228 is a portion that can be gripped by the operator. The grip portion 228 has a shape that allows the operator to easily move the second tip support portion 209 in a direction parallel to the tape feeding direction. The operator moves the second tip support portion 209 in a direction parallel to the tape feeding direction, thereby moving the tape feeding claw unit 208 and the return direction tape feeding claw unit 210 in a direction parallel to the tape feeding direction. be able to.

  The return direction tape feed claw unit 210 has basically the same configuration as the tape feed claw unit 208. The return direction tape feed claw unit 210 is disposed at a position facing the tape feed claw unit 208 at a position away from the tape feed claw unit 208 in a direction orthogonal to the surface of the support portion 202. The return direction tape feed claw unit 210 is fixed to the second tip support portion 209 and moves together with the second tip support portion 209 in the linear motion direction (direction in which the movable portion of the drive unit 204 moves). In the return direction tape feed claw unit 210, the direction of the feed claw in the linear motion direction is opposite to that of the tape feed claw unit 208. Further, in the return direction tape feed claw unit 210, the projection of the feed claw protrudes on the side opposite to the support portion 202 side.

  The interlocking mechanism 211 is a mechanism that transmits the power transmitted from the drive unit 204 to the first tip support unit 206 to the second tip support unit 209. As shown in FIG. 40, the interlocking mechanism 211 has a first slide mechanism 242, a transmission unit 244, and a second slide mechanism 246. The first slide mechanism 242 includes a fixed part 242a and a movable part 242b. The fixed portion 242a is fixed to the support portion 202. The movable part 242b is supported by the fixed part 242a so as to be movable in the linear movement direction (the direction in which the movable part of the drive unit 204 moves). The movable portion 242b is fixed to the first tip support portion 206 and moves together with the first tip support portion 206 in the linear movement direction.

  The transmission unit 244 is a power transmission mechanism that transmits the power transmitted from the first slide mechanism 242 to the second slide mechanism 246. The transmission part 244 has a pinion gear fixed to the support part with a pin.

  The second slide mechanism 246 includes a fixed part 246a and a movable part 246b. The fixing portion 246a is fixed to the support portion 202. The movable part 246b is supported by the fixed part 246a so as to be movable in the linear motion direction (the direction in which the movable part of the drive unit 204 moves). The movable portion 246b is fixed to the second tip support portion 209 and moves in the linear movement direction together with the second tip support portion 209.

  The interlocking mechanism 211 is configured as described above, and the transmission unit 244 is configured such that the pinion gear has a gear groove formed in the movable part 242b of the first slide mechanism 242 and a gear formed in the movable part 246b of the second slide mechanism 246. It is inserted into the groove. That is, in the interlocking mechanism 211, the transmission unit 244 and the first slide mechanism 242 are coupled by a rack and pinion mechanism, and the transmission unit 244 and the second slide mechanism 246 are coupled by a rack and pinion mechanism. As shown in FIG. 40, the interlocking mechanism 211 has a position where the transmission unit 244 and the first slide mechanism 242 are coupled to each other and a position where the transmission unit 244 and the second slide mechanism 246 are coupled to each other. It becomes the position to do. As a result, when the pinion gear rotates, the feed unit 200 moves the first slide mechanism 242 and the second slide mechanism 246 in directions opposite to each other in the linear motion direction.

The light emitting unit 584a and the light receiving unit 586a are arranged at positions where the holding position is sandwiched between them. When the measurement light output from the light emitting unit 584a is received by the light receiving unit 586a, the holding position side component detection sensor 582a detects that there is no electronic component in the measurement region (the holding position in the present embodiment). When the measurement light output from the light emitting unit 584a is not received by the light receiving unit 586a, the holding position side component detection sensor 582a detects that there is an electronic component in the measurement region (the holding position in this embodiment). Similarly, the holding position side component detection sensor 582b is an optical sensor having a light emitting portion 584b and a light receiving portion 586b, and the holding position side component detection sensor 582c is also an optical sensor having a light emitting portion 584c and a light receiving portion 586c. is there. The holding position side component detection sensors 582a, 582b, and 582c detect the presence or absence of an electronic component with the same configuration. In the bowl feeder unit 400, the holding position side component detection sensors 582a, 582b, and 582c detect the presence / absence of the electronic component at the holding position, and drive the bowl feeder unit 400 based on the detection result. For example, when the holding position side component detection sensors 582a, 582b, and 582c determine that there is no electronic component at the holding position, the bowl feeder unit 400 drives the driving device 408 to convey the electronic component.

  Further, when the electronic component mounting apparatus 10 performs an operation of holding the electronic component at the holding position of the bowl feeder unit 400 with the nozzle 32 of the head 15, the electronic components are held at the holding position by the holding position side component detection sensors 582a, 582b, and 582c. When it is detected that there is a component, a holding operation for holding the electronic component at the holding position is executed, and the holding position side component detection sensors 582a, 582b, and 582c detect that there is no electronic component at the holding position. If so, you may wait.

The guide unit 592 guides the electronic component that is not in an appropriate direction among the electronic components conveyed from the bowl 420 to the proximal end rail 504 to the bowl 420. That is, the guide unit 592 prevents electronic components conveyed in an inappropriate direction from entering the proximal end rail 504 among the electronic components conveyed to the proximal end rail 504. Specifically, the guide portion 592 has a plate-like member disposed at a position where the lead of the electronic component in an inappropriate direction comes into contact, and guides the electronic component contacted with the lead to the bowl 420.

  Further, the base end rail 504 is provided with a drop portion 594 on the upper side in the vertical direction of the region where air is blown by the air blow portion 590. The drop-in part 594 is disposed outside the base end rail 504 (on the side away from the bowl 420), and is provided with an inclination that approaches the bowl 420 as it goes upward in the vertical direction. The drop-in part 594 guides the electronic component, which is blown up by the air blow part 590 and pushed upward in the vertical direction, to the bowl 420 side by inclination. Thereby, it is possible to suppress the electronic component from jumping out of the bowl 420.

For example, the component supply device 402 can periodically return the electronic component at the target position to the bowl 420 by performing the air blow at the air blow unit 590 periodically. As a result, it is possible to eliminate electronic components that are conveyed while being inclined with respect to the rail 422 and are not carried into the rail 422 in the target region. In addition, the component supply device 402 can also exclude, with the air blow unit 590, an electronic component having an inappropriate orientation that could not be excluded with the guide unit 592. In the present embodiment, the air blow unit 590 is provided as a mechanism for returning the electronic components of the base end rail 504, which is the starting end of the rail 422, to the bowl 420, but is not limited thereto. For example, instead of the air blow unit 590, a mechanical mechanism may be used.

  Next, the operation of each part of the electronic component mounting apparatus will be described. Note that the operation of each part of the electronic component described below can be executed by controlling the operation of each part based on the control device 20.

FIG. 71 is an explanatory diagram for explaining the operation of recognizing the shape of the electronic component of the electronic component mounting apparatus. FIG. 72 is an explanatory diagram for explaining the recognition operation of the shape of the electronic component of the electronic component mounting apparatus. FIG. 73 is a schematic diagram illustrating an example of a recognition operation detection result. FIG. 74 is a schematic diagram illustrating an example of a recognition operation detection result.

  The electronic component mounting apparatus 10 measures the shape of the electronic component using the laser recognition device 38 as described above. As shown in FIG. 68, the laser recognizing device 38 outputs a laser beam from the light source 38a in a state in which the electronic component 80 is disposed between the light source 38a and the light receiving element 38b, and the laser beam reached by the light receiving element 38b. By detecting the light, the shape of the component disposed between the light source 38a and the light receiving element 38b is detected. Further, when the laser recognition device 38 detects the shape of the electronic component 80 adsorbed by the nozzle 32 in one direction, the nozzle driving unit 34 moves or rotates the nozzle 32 to move or rotate the electronic component 80 to thereby change the shape. Detect again. As described above, the laser recognition device 38 rotates the electronic component 80, so that the direction in which the laser light is applied to the electronic component 80 and the angle of the light receiving element 38b with respect to the electronic component 80 are changed as shown in FIG. Change.

  As shown in FIG. 70, the electronic component mounting apparatus 10 adjusts the height of the electronic component 80 in the Z-axis direction as step S11. In a state where 80 is arranged, a laser beam is irradiated to a certain area from the light source 38a. Thereafter, the electronic component mounting apparatus 10 starts rotation of the electronic component 80 (rotation in the θ direction) as step S12.

  Thereafter, when the rotation speed of the electronic component 80 reaches a constant speed, the electronic component mounting apparatus 10 starts measuring the shape of the electronic component 80 in the predetermined direction by the laser recognition device 38 in step S13. At this time, the laser recognizing device 38 irradiates laser light to a certain region from the light source 38a and receives the laser light by the light receiving element 38b with the electronic component 80 being disposed between the light source 38a and the light receiving element 38b. . Here, the laser light blocked by the electronic component 80 does not reach the light receiving element 38b or its intensity is reduced. Thereby, the laser recognition apparatus 38 can detect the shape of the electronic component 80 in the cross section of the measured angle from the distribution of the laser light received by the light receiving element 38b. In the present embodiment, the laser recognition device 38 detects the end of the laser beam received by the light receiving element 38b, and detects the outermost shape of the electronic component 80 in that direction. As step S14, the electronic component mounting apparatus 10 detects the shape of one round of the electronic component 80 by repeating the detection of the shape of the electronic component 80 by the method of step S13 while rotating the electronic component 80. Thereby, the shape of the electronic component 80 in all directions can be detected. In this way, the laser recognition device 38 detects the shape from the direction of one round and rolls up the detection results of each direction shape as shown in FIG. Can be accurately detected.

  Here, as described above, the electronic component mounting apparatus 10 of the present embodiment mounts the electronic component 80, which is a radial lead type electronic component, on the substrate 8. When the electronic component mounting apparatus 10 detects the shape of the electronic component 80 shown in FIG. 72, the detected shape differs depending on the height in the Z-axis direction to be measured. That is, the laser recognizing device 38 of the electronic component mounting apparatus 10 performs detection on the line A as shown in FIG. Different shapes are detected when detection is performed.

  For example, if the laser recognition device 38 measures the shape along the line A shown in FIG. 72, the shape of the main body 82 of the electronic component 80 can be detected as shown in FIG. Further, when the shape of the laser recognition device 38 is measured along the line B shown in FIG. 72, the shape of the lead 84 of the electronic component 80 can be detected as shown in FIG. Since the laser recognition device 38 detects the shape of the outermost part of the measurement height of the electronic component, the shape of the electronic component is a shape in which the outermost portions of the electronic components (outermost leads 84) are connected. Is detected. The laser recognition device 38 can detect the shape of the lower surface position of the main body 82 when measuring the shape along the line C shown in FIG. 72, and can measure the shape along the line D shown in FIG. The shape of the lower surface position of the lead 84 can be detected. The electronic component mounting apparatus 10 adjusts the height in the Z-axis direction of the nozzle 32 that sucks the electronic component 80, so that the position where the laser recognition device 38 measures the shape of the electronic component 80 is set to various positions. be able to.

  FIG. 75 is an explanatory diagram for explaining an operation of recognizing the shape of the electronic component of the electronic component mounting apparatus. The electronic component mounting apparatus 10 may use an electronic component 80a shown in FIG. 75 as an electronic component that is a radial lead type electronic component. The electronic component 80a has a notch 89 formed in a part of the main body 82a. In the electronic component 80a, a portion where the notch 89 is formed has a different shape from other electronic components. The orientation of the electronic component 80a can be determined by the position where the notch 89 is formed.

  Here, the control unit 60 of the electronic component mounting apparatus 10 according to the present embodiment has the operator set in advance the position of the electronic component to be mounted, that is, the electronic component sucked by the nozzle (the position of the electronic component in the Z-axis direction). If so, the laser recognition device 38 detects the shape of the electronic component at the position set by the operator. As described above, the electronic component mounting apparatus 10 can measure the shape of the electronic component based on the position set by the operator, thereby making the characteristic shape portion of the electronic component a measurement position. Identification and detection of the orientation of the electronic component can be performed with higher accuracy.

  In addition, although the electronic component mounting apparatus 10 demonstrated the case where the shape recognition of an electronic component was performed using the laser recognition apparatus 38, it is not limited to this. The electronic component mounting apparatus 10 may be performed by a camera (the VCS unit 17 of the present embodiment) that three-dimensionally measures the electronic component shape supported by the housing 11 as a state detection unit. A camera that three-dimensionally measures a known electronic component shape other than VCS may be used. Similar processing can be executed by measuring the interval between the lead tips of the electronic component to be measured, the bent shape of the lead, the shape of the component main body, and the like with a camera that three-dimensionally measures the shape of the electronic component.

The overall processing operation of the electronic component mounting apparatus 10 will be outlined with reference to FIG. The process shown in FIG. 76 is executed by the control device 20 controlling each unit. The electronic component mounting apparatus 10 reads a production program as step S52. The production program is created by a dedicated production program creation device, or created by the control device 20 based on various input data.

  After reading the production program in step S52, the electronic component mounting apparatus 10 detects the state of the apparatus in step S54. Specifically, the configuration of the component supply units 14f and 14r, the type of electronic component being filled, the type of nozzle prepared, and the like are detected. The electronic component mounting apparatus 10 detects the state of the apparatus in step S54, and when preparation is completed, the board is loaded as step S56. The electronic component mounting apparatus 10 carries in a board | substrate at step S56, and if a board | substrate is arrange | positioned in the position which mounts an electronic component, it will mount an electronic component on a board | substrate as step S58. The electronic component mounting apparatus 10 will carry out a board | substrate as step S60, if mounting of an electronic component is completed by step S58. When the electronic component mounting apparatus 10 carries out the board in step S60, it is determined in step S62 whether production is finished. If the electronic component mounting apparatus 10 determines that the production is not finished (No) in step S62, the electronic component mounting apparatus 10 proceeds to step S56, and executes the processing from step S56 to step S60. That is, processing for mounting electronic components on the board is executed based on the production program. If the electronic component mounting apparatus 10 determines that the production is finished (Yes) in step S62, the electronic component mounting apparatus 10 finishes this process.

  The electronic component mounting apparatus 10 can manufacture a board on which the electronic component is mounted by reading the production program and performing various settings as described above, and then mounting the electronic component on the board.

  Hereinafter, an example of processing for registering various pieces of information of electronic components to be mounted on the electronic component mounting apparatus 10 will be described with reference to FIGS. 77 to 83D. The electronic component mounting apparatus 10 determines various values of the mounting process based on the production program based on the registered electronic component information, and executes the mounting of the electronic component based on the determined value. Various pieces of electronic component information can be registered as a part of the production program, or can be registered as information of a single electronic component common to a plurality of production programs.

  The electronic component mounting apparatus 10 displays the operation screen 602 shown in FIG. 77 on the display unit 42 (touch panel 42a or vision monitor 42b). The operation screen 602 displays various input items. The operator can input information on the electronic component by performing various operations while the operation screen 602 is displayed. 77 shows a screen for inputting electronic component information as component data, the electronic component mounting apparatus 10 can also input board data, mounting data, suction data, and vision data.

  An operation screen 602 shown in FIG. 77 displays an input item 604 for inputting the component type of the electronic component and an input item 606 for inputting the packing form. In addition, the operation screen 602 is an item for inputting external dimensions including the horizontal, vertical, height, and lead length of the electronic component. And an item for inputting a package size (size of the electronic component main body). Further, the operation screen 602 displays tabs for displaying detailed items such as packing appearance, centering, additional information, expansion, and inspection. In addition, the operation screen 602 of the present embodiment includes a component provision angle input item 608 indicating an angle of an electronic component supplied to the holding position, a tape type input item, and an electronic component arrangement pitch as detailed items of the packing state. An input item of pitch information indicating is included.

  Here, the input item 604 is an item for inputting the type of electronic component to be registered. When an item is selected, a list of options 610 is displayed in a pull-down menu as shown in FIG. In the list 610, choices of insertion parts and other parts are displayed in addition to the types of various electronic parts. The operator can input information to the input item 604 of the component type by performing a determination operation with the cursor 612 set to a desired option.

  In the input item 608, 0 °, 90 °, 180 °, 270 °, and others can be selected as the component providing angle indicating the angle of the electronic component supplied to the input holding position. For example, as shown in FIG. 79A, when the target electronic component is the electronic component 614, the state in which the electronic component 614 is rotated by 90 ° is the posture of 0 °, 90 °, 180 °, and 270 °, respectively. The operator inputs an angle in the input item 608 based on which posture the electronic component 614 is supplied to the holding position of the electronic component supply device. The reference position of the angle of the electronic component 614 can be set by the operator.

  In addition, as shown in FIG. 79B, the electronic component mounting apparatus 10 may be held with the electronic component 616 inclined at a predetermined angle with respect to the tape 618. Here, the electronic component 616 is a film capacitor. When the posture does not correspond to any of 0 °, 90 °, 180 °, and 270 ° like the electronic component 616, the operator inputs the angle of the electronic component 616 in addition to the above. Here, when holding the electronic component 616, the head 15 preferably uses a gripping nozzle that holds the electronic component 616 as the nozzle 32. When the electronic component mounting apparatus 10 holds the electronic component 616 using the gripping nozzle, the contact surface of the gripping nozzle is adjusted by adjusting the angle of the nozzle based on the component provision angle input to the other of the input items 608. Can be set to an angle corresponding to the inclination of the electronic component 616, and the occurrence of holding errors can be reduced.

  When the electronic component mounting apparatus 10 displays the operation screen 602 shown in FIG. 77 on the display unit 42 (touch panel 42a or vision monitor 42b) and the tab of additional information is selected by the operation unit 40, the operation screen is displayed. An operation screen 620 shown in FIG. The operation screen 620 includes a loading push amount input item 622 and a suction push amount input item 624. In addition, the operation screen 620 also displays selection items for performing test hits, confirming component release with a sensor, correcting component suction position, performing auto teaching, or performing component skipping. Yes. Also displayed is a component discarding item for inputting an electronic component processing method when the component is discarded (when it is determined that the component cannot be mounted).

  The input item 622 is an item for setting a dimension for pushing the electronic component from the upper surface of the board at the time of mounting. “0” is a value at which the distance between the electronic component and the substrate is 0 in the design value. When the numerical value increases in the positive direction, the electronic component mounting apparatus 10 moves to a state where the electronic component is pushed downward in the vertical direction with respect to the substrate. By setting the push-in amount, the component is mounted without reaching the substrate due to the influence of the flatness of the substrate, etc., and it is possible to prevent the component from slipping on the cream solder during mounting. can do. It should be noted that the initial value is preferably a positive value, for example, 0.5 mm, in order to more reliably mount the electronic component on the substrate.

  The input item 624 is a push amount when holding the component. That is, this is an item for setting the distance between the nozzle and the electronic component when the nozzle holds the electronic component at the holding position of the electronic component supply apparatus. “0” is a value at which the distance between the electronic component and the nozzle holding portion becomes 0 in the design value. When the numerical value increases in the positive direction, the electronic component mounting apparatus 10 moves the nozzle to a state where it is pushed downward in the vertical direction with respect to the electronic component. By setting the push-in amount, the nozzles do not reach the electronic component due to variations in component dimensions (height), etc., and the phenomenon that the component cannot be picked up or gripped, or the chip-shaped electronic component stands This can be suppressed. In order to hold the electronic component with the nozzle more reliably, the initial value is preferably a positive value, for example, 0.2 mm.

  The operation screen 620 displays input items for the component layer. The input item of the component layer is an item for setting the priority for each component in the same mounting layer. By setting this item, it is possible to set the priority of the mounting order of the electronic components when producing in the optimization order.

  The operation screen 620 displays input items for gripper nozzle data. Here, the gripper nozzle is a gripping nozzle that grips and holds an electronic component. The pressing position is a position where the electronic component is pressed when gripping. The horizontal clearance is an item for inputting the clearance between the pressing surface of the fixed arm of the gripping nozzle and the component as a minus value. The suction nozzle direction is an item for inputting the nozzle direction at the time of suction when the component is supplied at 0 degree. The suction height fine adjustment value is an item for inputting an offset value of the gripping height (suction height) at the time of gripping.

  When the electronic component mounting apparatus 10 displays an operation screen 602 shown in FIG. 77 on the display unit 42 (touch panel 42a or vision monitor 42b) and the expansion tab is selected by the operation unit 40, the operation screen 602 is displayed. 81 displays an operation screen 630 shown in FIG. The operation screen 630 displays items for setting various conditions of the electronic component state detection process executed by the laser recognition device 38. The operation screen 630 includes an input item for setting the moving speed of the nozzle, a laser height input item 632, and a component shape input item 634. Here, the θ speed (during measurement) is an item for inputting the acceleration of the θ axis of the nozzle at the time of laser recognition, and the θ speed (not measured) is a rotation after laser centering, for example, a rotation for setting a mounting angle. This is an item for inputting the θ-axis acceleration of the nozzle in the case of the above.

  The input item 632 is an item for inputting the distance from the nozzle tip to the laser irradiation surface at the time of measurement. The input item 634 is an item for inputting the shape of the electronic component to be measured. As shown in FIG. 82, information on the component shape is input by designating with a cursor 638 from a list 636 on which options are displayed. Characteristic points for determining whether or not an electronic component is the shape when the laser recognition device 38 recognizes the shape of the electronic component by inputting the shape of the component, specifically the shape of the electronic component main body, in the input item 634 Can be specified. For example, when no missing corners are input to the input item 634, four vertices are detected. In the case of electronic components 640 and 641 shown in FIG. 83A, the positions of four vertices 1 to 4 are detected. Thereby, a position shift and an angle shift can be detected. Also, when there is a missing corner in the input item 634, 5 to 8 vertices are detected. In the case of the electronic component 642 shown in FIG. 83B, the positions of the six vertices 1 to 6 are detected. In the case of the electronic component 643 shown in FIG. 83B, the positions of eight vertices 1 to 8 are detected. Thereby, a position shift and an angle shift can be detected. When PLCC is input to the input item 634, eight vertices are detected. In the case of the electronic component 644 shown in FIG. 83C, the positions of eight vertices 1 to 8 are detected. In the case of PLCC, it is possible to detect positional deviation and angular deviation using four points from the detected eight vertices. When flexible is input to the input item 634, eight points in the vicinity where the component width in the XY direction is minimized are detected. In the case of the electronic components 646 and 647 shown in FIG. 83D, the positions of eight points 1 to 8 are detected. In the case of the electronic component 643 shown in FIG. 83D, the positions of eight vertices 1 to 8 are detected. Thereby, a position shift and an angle shift can be detected.

  The electronic component mounting apparatus 10 can display the operation screens 602, 620, 630, and the like as described above, and can acquire various information related to the electronic component. The electronic component mounting apparatus 10 can suitably mount the electronic component on the substrate by performing the mounting process of the electronic component based on various information related to the acquired electronic component. In addition, the electronic component mounting apparatus 10 is provided with various input items suitable for leadless electronic components having no leads (mounted electronic components) and leaded electronic components having insertion leads (inserted electronic components). Thus, processing corresponding to each electronic component can be executed. For example, the electronic component mounting apparatus 10 can input an insertion component indicating an insertion type electronic component as the component type. Thus, the electronic component mounting apparatus 10 detects the component type, thereby determining whether it is a mounted electronic component or an insertion type electronic component, that is, whether or not to insert a lead into a hole (insertion hole) in the board at the time of mounting (insertion). Can be detected).

  The operation of recognizing the shape of the electronic component will be described with reference to FIGS. 84 and 85 are flowcharts showing an example of the operation of the electronic component mounting apparatus, respectively. The processing shown in FIGS. 84 and 85 is executed by the control unit 60 controlling the operation of each unit.

  The process shown in FIG. 84 is a process for setting a position for measuring the shape of the electronic component. Here, the control unit 60 may perform the process shown in FIG. 84 every time when measuring the shape of the electronic component, or execute it for all the electronic components when setting the operation of mounting the electronic component on the board. Then, during the actual electronic component mounting process, the shape may be measured based on the result (measurement position setting result) determined by executing in advance.

  The control unit 60 determines whether a measurement position is set as step S112. Here, the measurement position setting is position information for measuring the shape set by the operator for the target electronic component, and the input value of the laser height on the operation screen. When determining that there is a setting (Yes) in Step S112, the control unit 60 sets a measurement position based on the setting in Step S114, that is, sets the measurement position set by the operator as the measurement position of the electronic component. This process is terminated. When determining that there is no setting (No) in step S112, the control unit 60 sets the reference position as the measurement position in step S116, and ends this process. Here, the reference position is a reference measurement position set according to the category of the electronic component, that is, whether it is a capacitor or an IC chip.

  In this way, the electronic component mounting apparatus 10 can set the measurement position by the operator, and can set the position arbitrarily set by the operator as the measurement position. The electronic component mounting apparatus 10 can set a plurality of measurement positions for one electronic component. For example, in the case of a radial lead type electronic component, it is possible to measure the shapes of two locations, the main body and the lead. Further, when the measurement position is set, the electronic component mounting apparatus 10 acquires information on the shape of the electronic component at the measurement position based on the setting. Note that the shape information may be the result of measurement using the laser recognition device 38 or the shape data of the electronic component input by the operator.

  Next, the process shown in FIG. 85 is a process before mounting the electronic component, specifically, a measurement process of the shape of the electronic component and a determination process based on the measurement result. Note that the control unit 60 executes the processing of FIG. 85 for all electronic components that hold the processing. The control unit 60 acquires data of electronic components to be held as step S120. Here, the data of the electronic component to be held (suction target, grip target) is various pieces of information necessary for mounting the electronic component on the substrate. The electronic component data to be held includes the position of the component supply device 100 that holds the electronic component, the shape data of the electronic component, the suction height (holding height) of the electronic component, and the electronic component by the laser recognition device 38. Information on measurement positions to be measured.

  After acquiring data in step S120, the control unit 60 determines a measurement position in step S122. That is, the control unit 60 determines the position for detecting the shape of the electronic component, that is, the position of the electronic component in the Z-axis direction based on the data acquired in step S120. In addition, the control part 60 may perform the process of step S120 and step S122 before adsorption | suction of an electronic component.

  When determining the measurement position in step S122 and sucking the electronic component with the nozzle, the control unit 60 adjusts the Z-axis position of the electronic component in step S124. That is, the control unit 60 moves the measurement position determined in step S122 of the electronic component to the measurement region of the laser recognition device 38 by moving the nozzle in the Z-axis direction. After adjusting the Z-axis position of the electronic component in step S124, the control unit 60 measures the shape of the electronic component in step S126. That is, the control unit 60 uses the laser recognition device 38 to detect the shape of the electronic component at the measurement position.

  When the control unit 60 detects the shape of the electronic component at the measurement position in step S126, the control unit 60 determines whether the measurement is completed in step S128. That is, the control unit 60 determines whether the measurement of the shape at the measurement position determined in step S122 is completed. If it is determined in step S128 that the measurement is not completed (No), the control unit 60 proceeds to step S124, performs the processes in steps S124 and S126 again, and measures the shape of the measurement position where the measurement has not been completed. The controller 60 detects the shape of the set measurement position by repeating the adjustment of the position of the electronic component and the measurement of the shape as described above.

  When it is determined that the measurement is finished (Yes) in step S128, the control unit 60 compares the measurement result with the reference data in step S130. Here, the reference data is data on the shape of the electronic component to be attracted (held) acquired in step S120. The control unit 60 compares the measurement result with the reference data to determine whether the sucked electronic component has a shape that matches the reference data, or whether the direction of the electronic component matches the direction of the reference data, or the like. To do.

  After performing the comparison in step S130, the control unit 60 determines whether the component is appropriate in step S132. Specifically, the control unit 60 determines in step S132 whether the electronic component is picked up in a state where it can be mounted. If the control unit 60 determines that the component is not appropriate (No) in step S132, the control unit 60 discards the electronic component sucked by the nozzle in step S134 and ends this process. The control unit 60 moves the head and nozzle to a position facing the component storage unit 19, and throws the electronic component held by the nozzle into the component storage unit 19, thereby discarding the electronic component. In addition, the control part 60 performs again the process which mounts the electronic component of the same kind in the same mounting position (mounting position) of a board | substrate.

  When it is determined in step S132 that the component is appropriate (Yes), the control unit 60 determines whether the component direction (direction in the rotation direction of the nozzle) is appropriate in step S136. That is, it is determined whether the sucked electronic component is the same as the reference direction. In addition, the control part 60 of this embodiment determines whether the electronic component is reversed as step S136. If the controller 60 determines in step S136 that the direction is not appropriate, that is, the electronic component is in an inverted state (No), the controller 60 inverts the electronic component in step S138 and then proceeds to step S140.

  When it is determined Yes in step S136 or when the process of step S138 is executed, the control unit 60 finely adjusts the mounting position (mounting position) of the electronic component based on the holding position as step S140. For example, based on the detection result of the shape of the electronic component, the position where the nozzle is sucking the electronic component is detected, and the relative position between the nozzle and the substrate at the time of mounting is adjusted based on the shift of the holding position with respect to the reference position. . The control part 60 will complete | finish this process, if the process of step S140 is performed. In addition, after performing the process of step S140 in FIG. 85, the control unit 60 mounts the electronic component on the board in consideration of the result of step S140 for the determined electronic component.

  As described above, the electronic component mounting apparatus 10 can appropriately mount the electronic component on the board by detecting the shape of the electronic component using the laser recognition device 38 and performing various processes based on the result.

  The electronic component mounting apparatus 10 discards the electronic component in step S134 of the flowchart shown in FIG. 85. However, when it is determined that the lead shape of the electronic component is inappropriate, a process for correcting the lead shape is executed. Also good. In other words, in step S134, the electronic component lead may be corrected (processed) into a shape that can be inserted and mounted at the mounting position (mounting position) without discarding the electronic component. Even if the electronic component mounting apparatus 10 corrects the lead of the electronic component by a mechanism that clamps the electronic component of the cut unit of the electronic component supply apparatus 100, the electronic component mounting apparatus 10 corrects the lead of the electronic component by a separately provided correction mechanism. May be. As processing means for processing the shape of the lead in this way, various means such as a mechanism for clamping the main body of the electronic component or the lead, a correction mechanism received separately, or the like can be used.

  Next, the operation for determining the mounting order (mounting order) of electronic components will be described with reference to FIGS. The mounting order includes the order of electronic components to be inserted. FIG. 86 is an explanatory diagram for explaining the operation of the electronic component mounting apparatus.

  The electronic component mounting apparatus 10 of the present embodiment includes a list 302 shown in FIG. 86 as production program data. The list 302 includes information on the mounting layer for the mounting point of the board (including the point to be inserted into the board) and information on the designation of the inserted component. Here, the mounting layer is priority information used when determining the mounting order of electronic components, and is set by a numerical value from 1 to 7. Here, the mounting layer is a numerical value in which the mounting order is determined to be earlier as the numerical value is smaller and the mounting order is determined to be later as the numerical value is larger. The mounted layer is a value set by the operator in consideration of various types of information. The insertion part designation is an item indicating whether or not an electronic part to be mounted on the mounting point is an insertion part. In FIG. 86, the mounting point designated as the insertion part is indicated by Yes. Here, the insertion component is an electronic component that mainly inserts a lead such as a radial lead type electronic component into a hole formed in the substrate. The insertion part designation is also information set by the operator. For this reason, regardless of the type of electronic component, the mounting point designated by the operator as an inserted component can be designated as an inserted component.

  The electronic component mounting apparatus 10 creates the mounting order list 304 using the information in the list 302. Here, in the mounting order list 304, the mounting point on the upper side of the list is the mounting point on which the electronic component is first mounted, and the mounting point on the lower side of the list is the mounting point on which the electronic component is mounted later. That is, the mounting order list 304 is displayed in order from the top in the order in which the electronic components are mounted. Here, the internal layer of the mounting order list 304 is information on the layer determined by the control unit 60 based on the mounting layer and the insertion component designation. The control unit 60 determines the mounting points on which the electronic components are mounted in order from the mounting point having the smallest internal layer value.

  FIG. 87 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. The process illustrated in FIG. 87 is an example of a process for creating the mounting order list 304 based on the list 302. The process shown in FIG. 87 is executed by the control unit 60 controlling the operation of each unit. The control part 60 reads a production program as step S200. The control unit 60 reads the production program from an external device or reads it from the storage unit of the electronic component mounting apparatus 10. After reading the production program in step S200, the control unit 60 acquires information on the mounting point n in step S202. Specifically, information on the mounting layer of the mounting point n and information on designation of the inserted part are acquired.

  When the information of the mounting point n is acquired in step S202, the control unit 60 determines whether or not the mounting point n = inserted part, that is, the insertion part designation information of the mounting point n is Yes in step S204. If the control unit 60 determines in step S204 that the mounting point n is not an insertion part (No), it sets internal layer = mounting layer in step S206. That is, the control unit 60 sets the numerical value of the mounting layer as the numerical value of the internal layer when the information for specifying the inserted part at the mounting point n is not Yes. After performing the process of step S206, the control unit 60 proceeds to step S210. When it is determined in step S204 that the mounting point n = inserted part (Yes), the control unit 60 sets internal layer = mounting layer + 7 in step S208. That is, when the information for specifying the inserted part at the mounting point n is Yes, the control unit 60 sets a numerical value obtained by adding 7 to the numerical value of the mounting layer as the numerical value of the internal layer. After performing the process of step S208, the control unit 60 proceeds to step S210.

  After performing the processing in step S206 or step S208, the control unit 60 determines in step S210 whether the mounting data is complete, that is, whether the internal layer has been calculated for all mounting points. If it is determined in step S210 that the process has not ended (No), the control unit 60 sets the mounting point n to n + 1 in step S212, and then proceeds to step S202. That is, the above-described processing is performed with the mounting point to be detected as an internal layer as the next mounting point.

  When it is determined in step S210 that the process has ended (Yes), that is, the internal layers of all the mounting points have been set, the control unit 60 determines the mounting order in step S214. That is, the control unit 60 determines the order of mounting the electronic components at the mounting points based on the set internal layer and various conditions. After determining the mounting order, the control unit 60 creates a mounting order list and ends this process.

  As described above, the electronic component mounting apparatus 10 is provided with an item that allows the operator to set whether or not the component is an insertion component. It can be mounted on the substrate later. Further, the operator can determine the mounting order of the target electronic component only by determining whether the component is an insertion component. Thereby, when setting the mounting layer, it is not necessary to set the mounting layer of the electronic component in consideration of the layer for the mounting layer. Thereby, it is possible to reduce the burden imposed on the operator by the operation of determining the mounted layer.

  The operation of the component supply device of the electronic component mounting apparatus will be described with reference to FIG. FIG. 88 is a flowchart showing an example of the operation of the electronic component mounting apparatus. The processing shown in FIG. 88 is executed by the component supply control unit 64 controlling the operation of each unit of the component supply device based on the processing of the control unit 60. The process shown in FIG. 88 is started in a state where no electronic component is arranged in the holding area. In step S260, the component supply control unit 64 moves the tape by one pitch. That is, the component supply control unit 64 moves the tape by one pitch by moving the feed claw of the feed unit one reciprocation or in the feed direction. Thereby, the electronic component held by the tape body is moved to the holding area.

  After moving the electronic component to the holding area in step S260, the component supply control unit 64 cuts the lead of the electronic component moved to the holding area in step S262. In other words, the component supply control unit 64 cuts the portion of the lead between the component main body and the tape main body with the cut unit. After cutting the lead in step S262, the component supply controller 64 maintains the clamped state in step S264. That is, the component supply control unit 64 maintains the state where the lead is sandwiched between the cut teeth after the lead wire is cut by the cut unit.

  After maintaining the clamped state in step S264, the component supply control unit 64 determines whether the nozzle 32 is holding (sucking or gripping) the electronic component in step S266. If the component supply control unit 64 determines in step S266 that the electronic component is not held by the nozzle (No), the component supply control unit 64 proceeds to step S264. The component supply control unit 64 maintains the clamped state of the electronic component until it is determined that the electronic component is held by the nozzle.

  If it is determined in step S266 that the electronic component is held by the nozzle (Yes), the component supply control unit 64 releases the electronic component in step S268, that is, releases the clamped state. As a result, the electronic component whose lead has been cut and separated from the tape is moved to a predetermined mounting position (mounting position) by the nozzle and mounted on the substrate.

  When the electronic component is released in step S268, the component supply control unit 64 determines whether there is a tape feed request in step S270. Here, the tape feed request is a request to move the tape by one pitch and move the next electronic component to the holding area. If the component supply control unit 64 determines that there is a request (Yes) in step S270, the component supply control unit 64 proceeds to step S260 and executes the above process again.

  If it is determined that there is no request (No) in step S270, the component supply control unit 64 determines whether the process is ended in step S272. If the component supply control unit 64 determines in step S272 that the process is not finished (No), the component supply control unit 64 proceeds to step S270. Further, when the component supply control unit 64 determines that the process is ended (Yes) in step S272, the process is ended.

  The component supply control unit 64 moves the electronic component to the holding region as described above, cuts and clamps the lead, and when the electronic component is attracted to the nozzle, releases the clamp to remove the radial lead type electronic component. The nozzle can be adsorbed in a movable state.

  FIG. 89 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. Note that the processing operation illustrated in FIG. 89 is an operation from the loading of the substrate to the completion of the mounting of the electronic component on the substrate. Also, the processing operation shown in FIG. 89 is executed by the control unit 60 controlling the operation of each unit.

  The control part 60 carries in a board | substrate as step S302. Specifically, the control unit 60 transports the substrate on which the electronic component is to be mounted to a predetermined position by the substrate transport unit 12. When the substrate is loaded in step S302, the control unit 60 performs holding movement in step S304. Here, the holding movement (suction movement) is a processing operation for moving the head main body 30 to a position where the nozzle 32 faces the electronic component 80 in the holding area of the component supply unit 14.

  After performing the holding movement in step S304, the control unit 60 lowers the nozzle 32 as step S306. That is, the control unit 60 moves the nozzle 32 downward to a position where the electronic component 80 can be held (sucked and gripped). After lowering the nozzle 32 in step S306, the control unit 60 holds the component with the nozzle 32 as step S308, and raises the nozzle 32 as step S310. When the control unit 60 raises the nozzle to a predetermined position in step S310, specifically, moves the electronic component 80 to the measurement position of the laser recognition device 38, the electronic component sucked by the nozzle 32 is set in step S312. Detect the shape. When detecting the shape of the electronic component in step S312, the control unit 60 raises the nozzle in step S314. Note that the control unit 60 detects the shape of the component in step S312 as described above, and when it is determined that the held electronic component cannot be mounted, the electronic component is discarded and the electronic component is attracted again. When the control unit 60 raises the nozzle to a predetermined position, as step S316, the processing operation of moving the electronic component sucked by the nozzle 32 to a position facing the mounting position (mounting position) of the substrate 8 is performed. In step S318, the nozzle 32 is lowered, and in step S320, component mounting (component mounting), that is, a processing operation for releasing the electronic component 80 from the nozzle 32 is performed. In step S322, the nozzle 32 is raised. That is, the control part 60 performs the mounting process mentioned above in the processing operation from step S312 to step S320.

  When the nozzle is raised in step S322, the control unit 60 determines in step S324 whether mounting of all components is completed, that is, whether mounting processing of the electronic components to be mounted on the board 8 is completed. If the control unit 60 determines in step S324 that the mounting of all the components has not been completed (No), that is, the electronic component to be mounted remains, the process proceeds to step S304, and the next electronic component is placed on the substrate 8. Execute the processing operation to be installed. In this way, the control unit 60 repeats the above processing operation until the mounting of all components on the board is completed. If the control unit 60 determines in step S324 that all parts have been mounted (Yes), the process ends.

  Next, the operation of the component supply device 100 and the head 15 before and after the nozzle picks up the electronic component held by the component supply device 100 will be described with reference to FIG. FIG. 90 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. The processing shown in FIG. 90 is executed by the control unit 60 controlling the operation of each unit.

  In step S340, the control unit 60 performs XY suction movement of the head 15, and starts clamping electronic components by the component supply apparatus 100. That is, the control unit 60 moves the head 15 in the XY direction and moves the nozzle 32 to the holding area in step S340. In addition, the control unit 60 arranges the electronic components in the holding area of the component supply device 100, and then the leads are cut and clamped.

  When the control unit 60 performs the process of step S340 and the holding position movement of the head 15 is completed as step S342, that is, when the nozzle 32 of the head 15 is moved to the holding area, the clamp waiting time and the elapsed time are determined as step S344. And in step S346, it is determined whether the waiting time has elapsed, that is, whether the elapsed time is equal to or longer than the clamp waiting time.

  If the control unit 60 determines in step S346 that the waiting time has not elapsed (No), that is, the elapsed time is less than the clamp waiting time, the control unit 60 proceeds to step S344. The control unit 60 repeats the processes of steps S344 and S346 until the waiting time elapses.

  When it is determined in step S346 that the waiting time has elapsed (Yes), the control unit 60 performs the Z-axis suction lowering in step S348. That is, the control unit 60 moves the nozzle downward in the Z-axis direction to a position where the electronic component in the holding area can be picked up. After performing the Z-axis suction and descent in step S348, the controller 60 picks up the component in step S350, that is, sucks the electronic component with the nozzle, and compares the clamp release waiting time with the existing Z-axis descent time in step S352. . Here, the clamp release waiting time is a processing time necessary for releasing the clamped state of the electronic component clamped by the component supply apparatus 100. The waiting time when the existing Z-axis is lowered is a time for waiting at a position where the nozzle of the head sucks the electronic component. In addition, the waiting time at the time of the existing Z-axis descent is a preset value, and is a time required for the electronic component suction processing.

  After performing the comparison in step S352, the control unit 60 determines in step S354 whether the clamp release waiting time is greater, that is, whether the existing Z-axis descent waiting time is less than the clamp release waiting time. When it is determined in step S354 that the clamp release waiting time is greater (Yes), that is, the existing Z-axis descent time is less than the clamp release waiting time, the control unit 60 waits for the clamp release waiting time as step S356. Then, the process proceeds to step S360. If the controller 60 determines in step S354 that the clamp release waiting time is not larger (No), that is, if the existing Z-axis lowering waiting time ≧ clamp release waiting time, then the existing Z-axis is determined as step S358. The process waits for the waiting time during descent, and proceeds to step S360.

  After performing the processes of steps S356 and S358, the control unit 60 performs the Z-axis suction rise of the head and the feed operation of the component supply device as step S360, and ends this process.

  The electronic component mounting apparatus 10 can mount the electronic component on the board by executing the processing operations shown in FIGS. 89 and 90.

  Next, with reference to FIGS. 91 to 92B, an example of processing in a case where the electronic component at the holding position of the electronic component supply apparatus 100 is held by the nozzle will be described. FIG. 91 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. FIG. 92A is an explanatory diagram for explaining the operation of the electronic component mounting apparatus. FIG. 92B is an explanatory diagram for explaining the operation of the electronic component mounting apparatus. The process shown in FIG. 91 can be executed by the control device 20 of the electronic component mounting apparatus 10 controlling each unit.

  In step S402, the electronic component mounting apparatus 10 performs an electronic component holding operation using a nozzle. That is, the electronic component mounting apparatus 10 performs an operation of holding (sucking and gripping) the electronic component in the holding area of the electronic component supply apparatus with the nozzle. After executing the holding operation in step S402, the electronic component mounting apparatus 10 detects the holding state of the electronic component in step S404. Specifically, it is detected by the laser recognition device 38 and the VCS unit 17 whether the nozzle holds an electronic component.

  When the electronic component mounting apparatus 10 detects the holding state in step S404, the electronic component mounting apparatus 10 determines whether the nozzle holds the electronic component in step S406. If the electronic component mounting apparatus 10 determines in step S406 that the electronic component is held (Yes), the process ends. If it is determined in step S406 that the electronic component is not held (No), the electronic component mounting apparatus 10 detects the state of the holding position of the electronic component supply device in step S408. For example, the electronic component mounting apparatus 10 detects the height of the holding position with the height sensor 37 and detects whether there is an electronic component at the holding position. The presence or absence of electronic components may be detected by photographing with the photographing device 36.

  When the electronic component mounting apparatus 10 detects the state of the holding position in step S408, the electronic component mounting apparatus 10 determines whether there is an electronic component in the holding position in step S410. If the electronic component mounting apparatus 10 determines in step S410 that there is an electronic component (Yes), the electronic component mounting apparatus 10 proceeds to step S416. If it is determined that there is no electronic component (No), the electronic component mounting apparatus 10 proceeds to step S412. Here, the electronic component mounting apparatus 10 detects the presence or absence of the electronic component based on the height of the holding position by the height sensor 37. For example, as shown in FIG. 92A, when the electronic component 80 is in the holding area, the height of the holding area is high. As shown in FIG. 92B, when the electronic component 80 is not in the holding area, the height of the holding area is high. Becomes lower (becomes the tape position). As described above, the electronic component mounting apparatus 10 determines that there is an electronic component when the height of the holding region is higher than the threshold, and determines that there is no electronic component when the height is lower than the threshold.

  When it is determined No in step S410, the electronic component mounting apparatus 10 determines whether the number of feeding operations is equal to or greater than the threshold number as step S412. Here, the feeding operation is an operation in which the electronic component supply apparatus 100 feeds the tape by the arrangement interval of the electronic components. The number of feed operations in step S412 is the number of times that the feed operation has been performed in a state where electronic components cannot be picked up. If the electronic component mounting apparatus 10 determines that the number of feeding operations is equal to or greater than the threshold number (Yes) in step S412, the electronic component mounting apparatus 10 proceeds to step S416 and determines that the number of feeding operations is not equal to or greater than the threshold number (No). If so, the process proceeds to step S414.

  If the electronic component mounting apparatus 10 determines No in step S412, the electronic component mounting apparatus 10 performs a tape feeding operation as step S414, and proceeds to step S402. If the electronic component mounting apparatus 10 determines Yes in step S410 or step S412, the electronic component mounting apparatus 10 executes an error process as step S416 and ends the process. If the electronic component mounting apparatus 10 determines Yes in step S410, the electronic component mounting apparatus 10 notifies that the electronic component remains in the holding position as error processing. If the electronic component mounting apparatus 10 determines Yes in step S412, the electronic component mounting apparatus 10 notifies that the component cannot be confirmed even if the electronic component supply apparatus 100 performs the feeding operation a predetermined number of times as error processing.

  In this way, when no electronic component remains in the holding position, the electronic component mounting apparatus 10 feeds the tape and re-executes the holding operation of the electronic component, so that the portion where the electronic component is not arranged on the tape is obtained. Even if it exists, mounting of an electronic component can be continued, without stopping an apparatus. In addition, the electronic component mounting apparatus 10 is mounted when the electronic component whose lead has been cut by the electronic component supply apparatus 100 is not held by the nozzle and is moved from the holding position but no electronic component remains at the holding position. By continuing the operation, the electronic component can be mounted more efficiently.

  FIG. 93 is an explanatory diagram showing an example of a nozzle. FIG. 94 is an explanatory diagram for explaining the holding operation of the nozzle of FIG. 93 and 94 are diagrams showing an example of a gripping nozzle (gripper nozzle). The nozzle 690 shown in FIGS. 93 and 94 has a fixed arm 692 and a movable arm 694. The nozzle 690 is fixed in a state in which the fulcrum 695 of the movable arm 694 is rotatable to the main body of the nozzle 690, and the movable arm 694 faces the fixed arm 692 around the fulcrum 695 as the fixed arm 692. It can move in a direction away from the direction. The movable arm 694 is connected to the drive unit 696 on the opposite side of the main body portion of the nozzle 690 and the portion approaching or moving away from the fixed arm 692 via a fulcrum 695. The drive unit 696 is moved by a drive source (air pressure) that drives the suction nozzle. The movable arm 694 moves in a direction away from the direction in which the portion facing the fixed arm 692 approaches the fixed arm 692 as the driving unit 696 moves.

  The nozzle 690 grips the electronic component 80 as shown in FIG. 94 by reducing the distance between the fixed arm 692 and the movable arm 694 while the electronic component 80 is between the fixed arm 692 and the movable arm 694. can do.

  The gripping nozzle is not limited to the nozzle 690 and can have various shapes. 95A to 95D are explanatory diagrams showing examples of nozzles. The nozzle 690a shown in FIG. 95A, the nozzle 690b shown in FIG. 95B, the nozzle 690c shown in FIG. 95C, and the nozzle 690d shown in FIG. 95D are different in the distance between the fixed arm and the movable arm and in the movable range. For this reason, the shapes of electronic components that can be gripped differ from nozzle 690a to nozzle 690d.

  The electronic component mounting apparatus 10 can appropriately hold the electronic component by selecting the type of nozzle that holds the electronic component according to the type of electronic component to be held. Specifically, one electronic component can be mounted by selecting whether to use a suction nozzle or a gripping nozzle according to the electronic component to be held, and switching which nozzle to use among each type of nozzle. More kinds of electronic components can be mounted on the device.

  Next, an example of processing while the electronic component mounting apparatus is mounting the electronic component will be described with reference to FIG. FIG. 96 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. In step S450, the electronic component mounting apparatus 10 identifies the electronic component held by each nozzle of the head. That is, the type of electronic component held by the nozzle is specified next.

  After identifying the electronic component in step S450, the electronic component mounting apparatus 10 determines whether there is a nozzle replacement in step S452. If the electronic component mounting apparatus 10 determines in step S452 that the nozzle is not replaced (No), the electronic component mounting apparatus 10 proceeds to step S456. If the electronic component mounting apparatus 10 determines in step S452 that the nozzle has been replaced (Yes), the electronic component mounting apparatus 10 performs nozzle replacement in step S454. Specifically, the electronic component mounting apparatus 10 moves the head 15 to the replacement nozzle holding mechanism 18, moves the nozzle held by the head to the replacement nozzle holding mechanism 18, and is held by the replacement nozzle holding mechanism 18. Attach the nozzle to be used to the head. The electronic component mounting apparatus 10 changes the nozzle mounted on the head by the replacement nozzle holding mechanism 18 from the suction nozzle to the gripping nozzle, changes the type of the suction nozzle, or changes the type of the gripping nozzle. When the electronic component mounting apparatus 10 performs the processing of step S454 or when it is determined No in step S452, the electronic component mounting apparatus 10 is identified in step S450 using the electronic component holding operation, that is, the nozzle mounted on the head 15 as step S456. The electronic component holding operation is executed, and the present process is terminated.

  As shown in FIG. 96, the electronic component mounting apparatus 10 can hold the electronic component with a more appropriate nozzle by replacing the nozzle attached to the head according to the type of the electronic component. Further, by making the nozzle replaceable, both the lead type electronic component and the mounted type electronic component can be appropriately held by one electronic component mounting apparatus 10. In addition, more types of electronic components can be held. The electronic component mounting apparatus 10 can hold both the electronic components using a common nozzle by holding the main body portion, that is, the portion that is not the lead, for both the lead type electronic component and the mounted type electronic component. it can. As a result, the lead-type electronic component can be held without providing a dedicated nozzle for holding the lead. In addition, since the said effect can be acquired, although it is preferable to hold | maintain the main body of a lead type electronic component, you may provide the nozzle which hold | maintains a lead.

  Next, with reference to FIGS. 97 and 98, an example of processing from execution of setup processing (setting of a production program, preparation of each part, adjustment of a component supply device, etc.) to start of production will be described. FIG. 97 is a flowchart showing an example of the operation of the electronic component mounting apparatus. FIG. 98 is an explanatory diagram for explaining the operation of the electronic component mounting apparatus. Note that the process of FIG. 97 can also be executed as a process from when production is temporarily stopped to when it is resumed.

  In step S460, the electronic component mounting apparatus 10 executes a setup process. In step S462, the electronic component mounting apparatus 10 cuts the lead of the electronic component by the cutting unit of the electronic component supply apparatus 100, and clamps the electronic component. Note that the process of step S462 is executed as a part of the setup process of step S460. The electronic component mounting apparatus 10 is not held by the head after clamping the electronic component.

  The electronic component mounting apparatus 10 outputs a message as step S464, if the process of step S462 is performed. Specifically, a screen 698 shown in FIG. 98 is displayed as a message. The screen 698 displays a message “Do you want to maintain the clamped state”, a Yes button 699a, and a No button 699b.

  The electronic component mounting apparatus 10 displays a message in step S464, and when one of the buttons 699a and 699b is selected and determined, in step S466, the electronic component mounting apparatus 10 determines whether to maintain the clamped state. If the electronic component mounting apparatus 10 does not maintain the clamped state in step S466 (No), that is, if it is determined that the button 699b is selected, the clamped state is released and the electronic component is released in step S467, and this process ends. To do. In this case, the operator collects the electronic component from the holding area. In the present embodiment, an inquiry is made as to whether the clamped state is to be maintained, but conversely, an inquiry may be made as to whether to release the clamped state. In this case, the correspondence between Yes and No is reversed.

  The electronic component mounting apparatus 10 maintains the clamped state in step S466 (Yes), that is, if it is determined that the button 699a is selected, the clamped state is maintained as step S468, and the clamped electronic is started after production is started as step S469. The part is used and the process is terminated.

  As shown in FIG. 97, the electronic component mounting apparatus 10 supplies the electronic component after starting production of the electronic component with the lead cut in the setup process for the purpose of adjusting the cutting position of the electronic component. By using it as the first electronic component of the apparatus, the burden on the operator can be reduced. Specifically, it is possible to eliminate the trouble of collecting the electronic components and the trouble of manually inserting the collected electronic components into the substrate.

  Next, an example of processing executed by the electronic component mounting apparatus 10 when mounting the electronic component will be described with reference to FIG. FIG. 99 is a flowchart showing an example of the operation of the electronic component mounting apparatus.

  The electronic component mounting apparatus 10 specifies the position where the electronic component is mounted in step S470, and detects the height of the mounting position in step S472. The height of the board at the mounting position can be detected by the height sensor 37. When detecting the height in step S472, the electronic component mounting apparatus 10 determines in step S474 whether the height is equal to or less than the threshold value (whether the distance between the head and the measurement position is longer than the threshold value). That is, the electronic component mounting apparatus 10 determines whether there is anything on the board where the electronic component is mounted.

  If the electronic component mounting apparatus 10 determines in step S474 that the height is not less than or equal to the threshold value (No), that is, if the height is higher than the threshold value, it determines that something is on the mounting position, and step S476. Error processing is performed, and this processing is terminated. If the electronic component mounting apparatus 10 determines in step S474 that the height is equal to or lower than the threshold value (Yes), it determines that nothing is on the mounting position, and executes electronic component mounting processing in step S478. Then, this process ends.

  As shown in FIG. 99, the electronic component mounting apparatus 10 detects the height of the substrate at the position where the electronic component is mounted, and executes error processing when the height of the substrate is high, so that the position where the substrate is mounted. When there is an obstacle such as another member, it is possible to suppress the operation of mounting the electronic component. Thereby, an electronic component can be mounted, suppressing damaging a board | substrate and an electronic component. In FIG. 99, since the processing can be simplified, the height sensor 37 detects the height of the substrate, but the imaging device 36 may detect the state of the mounting position on the substrate.

  Next, using FIG. 100 to FIG. 109, among the processing operations of the electronic component mounting apparatus, the operation of mounting the electronic component on the mounting position (mounting position) of the substrate, specifically, the nozzle is moved in the Z-axis direction. The operation at the time of making will be described. FIG. 100 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. FIG. 101 is an explanatory diagram illustrating an example of a lead-type electronic component. Note that the process shown in FIG. 100 is preferably executed during the setup operation (optimization process) based on the production program and the teaching result. In this case, the electronic component mounting apparatus 10 may control the operation based on the result calculated by the setup operation at the time of production, that is, when the process of actually mounting the electronic component on the board is executed. The electronic component mounting apparatus 10 may perform the process shown in FIG. 100 at the time of production, that is, when the process of actually mounting the electronic component on the board is executed. Moreover, the electronic component mounting apparatus 10 performs the process shown in FIG. 100 for each electronic component mounted on the board.

  The electronic component mounting apparatus 10 determines whether it is a lead type electronic component as step S502. That is, the electronic component mounting apparatus 10 determines whether the electronic component (processing target electronic component) to be mounted on the substrate is an electronic component that inserts a lead into the insertion hole of the substrate. If the electronic component mounting apparatus 10 determines in step S502 that the electronic component mounting apparatus 10 is not a lead-type electronic component (No), in step S504, the electronic component mounting apparatus 10 calculates a movement pattern in the Z-axis direction based on the first speed reference, and ends this process. Note that the processing in step S504 will be described later.

  If the electronic component mounting apparatus 10 determines in step S502 that it is a lead-type component (Yes), it determines in step S506 whether the lead is formed. Here, the lead is formed is a state in which the lead is not in a linear shape, but a curved portion and a refracting portion are formed. For example, when a curved portion is formed on the lead 704 connected to the main body 702 as in the electronic component 700 shown in FIG. 101, the lead 704 is a formed electronic component. A connector or the like is excited as the electronic component with the lead formed. In addition, the electronic component can be made difficult to be removed after being inserted into the insertion hole by forming the lead, that is, by providing a curved portion or a refracting portion. In other words, the formed part functions as a retainer.

  If the electronic component mounting apparatus 10 determines in step S506 that the lead is not formed (No), in step S508, the electronic component mounting apparatus 10 calculates the movement pattern in the Z-axis direction based on the second speed reference, and ends the present process. The process in step S508 will be described later. If it is determined in step S506 that the lead is formed (Yes), the electronic component mounting apparatus 10 calculates a movement pattern in the Z-axis direction based on the third speed reference in step S510, and ends this process. The process of step S510 will be described later.

  Next, the processing in step S504, that is, the method for calculating the movement pattern in the Z-axis direction based on the first speed reference will be described with reference to FIGS. FIG. 102 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. FIG. 103 is an explanatory diagram showing the relationship between the moving speed of the nozzle and time. Here, step S504 is executed when it is determined that the electronic component is not a lead-type electronic component, that is, a mounted electronic component in which no lead is inserted into the insertion hole. That is, it is executed when the electronic component to be processed is a mounted electronic component.

  The electronic component mounting apparatus 10 acquires a component height as step S520. Specifically, information on the height of the electronic component is acquired. The height of the electronic component is the height of the electronic component in the Z-axis direction. When the electronic component mounting apparatus 10 detects the component height in step S520, the electronic component mounting apparatus 10 calculates the distance in the Z-axis direction between the mounting position and the nozzle in step S522. Specifically, the distance between the mounting position and the nozzle when the head is moved to the mounting position and the nozzle is moved in the Z-axis direction is calculated. Note that the processing order of step S520 and step S522 may be reversed. Moreover, although the information of step S520 and step S522 can be acquired based on the conditions previously input, you may acquire by measurement.

  After calculating the distance between the mounting position and the nozzle in step S522, the electronic component mounting apparatus 10 determines a condition for decelerating from the speed V1 to the speed V2 in step S524, and determines a condition for decelerating from the speed V2 in step S526. Then, this process ends. Here, the speeds V1 and V2 are movement speeds in the Z-axis direction. The condition for decelerating from the speed V1 to the speed V2 is a condition for decelerating the moving speed of the nozzle from the speed V1 to the speed V2 when moving in the Z-axis direction. In the electronic component mounting apparatus 10, the condition for decelerating from the speed V2 is a condition for further decelerating the moving speed of the nozzle from the speed V2 when moving in the Z-axis direction.

  The electronic component mounting apparatus 10 determines the nozzle movement pattern shown in FIG. 103 by determining the conditions for changing (decelerating) the nozzle movement speed in steps S524 and S526. FIG. 103 shows the relationship between the moving speed of the nozzle and time, that is, the moving speed of the nozzle at each time. In the movement pattern based on the first speed reference shown in FIG. 103, when the nozzle starts moving to the mounting position (nozzle lowering), the nozzle accelerates to the speed V1, and then moves to the time V1 at the speed V1. Thereafter, the nozzle starts decelerating at time t1 and decelerates to speed V2 at time t2. Here, the time t2 is a time when the distance between the lower end of the electronic component and the substrate becomes a set distance. Specifically, this is the time when the lower end of the electronic component and the substrate are close to a certain distance. Thereafter, the nozzle moves at a constant speed until time t3, starts decelerating at time t3, and then stops.

  The electronic component mounting apparatus 10 moves the electronic component according to the movement pattern shown in FIG. 103, so that the electronic component is moved within a certain distance of the substrate at time t1 (that is, in a range farther than the certain distance). Speed) The electronic component can be moved at V1. Thereafter, a speed slower than the speed V1 until the electronic component is mounted (mounted) on the substrate, that is, until the mounting is completed after the electronic component approaches within a certain distance of the substrate (that is, within a certain distance). The electronic component can be moved at a speed (third speed) V2. Thus, the electronic component can be moved quickly in a range where the substrate is not affected, and the electronic component can be moved slowly in a range where the substrate may be affected. As a result, the time required for mounting can be shortened while maintaining the accuracy of mounting on the substrate. The electronic component mounting apparatus 10 can press the electronic component against the substrate by determining the time t3 so that the electronic component is moved at a constant speed even after the electronic component and the substrate are in contact with each other and then stopped. The solder of the substrate and the electronic component can be brought into contact with each other by pressing.

  Next, the processing in step S508, that is, a method for calculating the movement pattern in the Z-axis direction based on the second speed reference will be described with reference to FIGS. FIG. 104 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. FIG. 105 is an explanatory diagram showing the relationship between the moving speed of the nozzle and time. 106 and 107 are explanatory diagrams for explaining an example of the operation of the electronic component mounting apparatus, respectively. Here, in step S508, it is determined that the electronic component is a lead-type electronic component, the lead is not formed, that is, the lead-type electronic component in which the lead is inserted into the insertion hole, and the lead is linear. If executed. That is, it is executed when the electronic component to be processed is a lead-type electronic component that is not formed.

  The electronic component mounting apparatus 10 acquires a component height as step S530. Specifically, information on the height of the electronic component is acquired. The height of the lead type electronic component is the height in the Z-axis direction of the electronic component, that is, the component height 87 obtained by adding the height of the main body 82 and the lead 84 of the electronic component as shown in FIG. After acquiring the component height (component length) in step S530, the electronic component mounting apparatus 10 acquires the lead length in step S532. Here, the lead length is the height of the lead 84 in the Z-axis direction, that is, the length 86 of the lead 84 of the electronic component as shown in FIG. After obtaining the lead length 86 in step S532, the electronic component mounting apparatus 10 calculates the distance in the Z-axis direction between the mounting position and the nozzle in step S534. Specifically, the distance between the mounting position and the nozzle when the head is moved to the mounting position and the nozzle is moved in the Z-axis direction is calculated. Note that the processing order of step S530, step S532, and step S534 may be reversed. Moreover, although the information of step S530, step S532, and step S534 can be acquired based on the conditions previously input, you may acquire by measurement.

  After calculating the Z-axis direction distance between the mounting position and the nozzle in step S534, the electronic component mounting apparatus 10 determines a condition for decelerating from the speed V1 to the speed V3 in step S536, and based on the lead length in step S538. Then, the condition for decelerating from the speed V3 is determined, and this process is terminated. Here, the speeds V1 and V3 are movement speeds in the Z-axis direction. The condition for decelerating from the speed (first speed) V1 to the speed (second speed) V3 is a condition for decelerating the moving speed of the nozzle from the speed V1 to the speed V3 when moving in the Z-axis direction. In the electronic component mounting apparatus 10, the condition for decelerating from the speed V3 is a condition for further decelerating the moving speed of the nozzle from the speed V3 when moving in the Z-axis direction. The speed V3 is a speed slower than the speed V2 described above.

  The electronic component mounting apparatus 10 determines the nozzle movement pattern shown in FIG. 105 by determining the conditions for changing (decelerating) the nozzle movement speed in steps S536 and S538. FIG. 105 shows the relationship between the moving speed of the nozzle and time, that is, the moving speed of the nozzle at each time. In the movement pattern based on the second speed reference shown in FIG. 105, when the nozzle starts moving to the mounting position (nozzle lowering), the nozzle accelerates to the speed V1, and then moves to the speed V1 until time t4. Thereafter, the nozzle starts decelerating at time t4 and decelerates to speed V3 at time t5. Here, as shown in FIG. 106, the time t5 is a time when the distance between the lower end of the electronic component (that is, the lower end of the lead 84) and the substrate becomes a set distance. Specifically, this is the time when the lower end of the electronic component and the substrate are close to a certain distance. Thereafter, the nozzle moves at a constant speed until time t6, starts decelerating at time t6, and then stops. Here, when mounting the electronic component with the movement pattern shown in FIG. 105, the electronic component mounting apparatus 10 inserts the lead 84 into the insertion hole of the board as shown in FIG. 107 between time t5 and time t6.

  The electronic component mounting apparatus 10 moves the electronic component according to the movement pattern of FIG. 107 so that the electronic component moves within a certain distance of the substrate at time t4 (that is, in a range farther than the certain distance) (first speed). ) Electronic components can be moved with V1. After that, until the electronic component is mounted (mounted) on the board, that is, from when the electronic component approaches within a certain distance of the board until the lead is inserted into the insertion hole to complete the mounting (that is, within a certain distance). The electronic component can be moved at a speed (second speed) V3 that is slower than the speed V1. Thus, the electronic component can be moved quickly in a range where the substrate is not affected, and the electronic component can be moved slowly in a range where the substrate may be affected. As a result, the time required for mounting can be shortened while maintaining the accuracy of mounting on the substrate.

  The electronic component mounting apparatus 10 stably inserts the lead into the board by detecting the timing of deceleration from the speed V3 based on the lead length, that is, by determining the interval from time t5 to time t6. be able to. Further, the electronic component can be moved until the main body 82 and the substrate approach a certain distance. In other words, the electronic component mounting apparatus 10 can adjust the moving condition of the electronic component when inserting the lead into the insertion hole, which cannot be adjusted only by the component height, by using the lead length as a criterion. it can. Specifically, if the height of the main body 82 of the lead-type electronic component is the component height, the lead may decelerate after contacting the substrate. If the component height 87 of the lead-type electronic component is the component height, Although it is necessary to adjust the push-in amount for each component, in this embodiment, by inputting the lead length as a parameter, various conditions can be determined according to the length.

  Further, in the case of a lead-type electronic component, the electronic component mounting apparatus 10 can adjust the pressure that presses the main body of the electronic component against the substrate after the electronic component and the substrate are in contact with each other by adjusting the timing at time t6. . Thereby, the main body can be moved with respect to the substrate under different conditions from the mounted electronic component that presses the terminal against the solder paste.

  Next, the processing in step S510, that is, a method for calculating the movement pattern in the Z-axis direction based on the third speed reference will be described with reference to FIGS. FIG. 108 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. FIG. 109 is an explanatory diagram showing the relationship between the moving speed of the nozzle and time. Here, in step S510, it is determined that the electronic component is a lead-type electronic component, the lead is formed, that is, the lead-type electronic component in which the lead is inserted into the insertion hole, and the lead is not linear. If executed. That is, it is executed when the electronic component to be processed is a lead-type electronic component that is formed.

  The electronic component mounting apparatus 10 acquires a component height as step S540. Specifically, information on the height of the electronic component is acquired. After acquiring the component height in step S540, the electronic component mounting apparatus 10 acquires the lead length in step S541. After acquiring the lead length in step S541, the electronic component mounting apparatus 10 calculates the distance in the Z-axis direction between the mounting position and the nozzle in step S542. Specifically, the distance between the mounting position and the nozzle when the head is moved to the mounting position and the nozzle is moved in the Z-axis direction is calculated. Note that the processing order of step S540, step S541, and step S542 may be reversed. Moreover, although the information of step S540, step S541, and step S542 can be acquired based on conditions input in advance, it may be acquired by measurement.

  After calculating the distance between the mounting position and the nozzle in step S542, the electronic component mounting apparatus 10 determines a condition for decelerating from the speed V1 to the speed V4 in step S544, and in step S546, the speed V4 based on the lead length. From this, the conditions for deceleration are determined, and this process is terminated. Here, the speeds V1 and V4 are movement speeds in the Z-axis direction. The condition for decelerating from the speed (first speed) V1 to the speed (fourth speed) V4 is a condition for decelerating the moving speed of the nozzle from the speed V1 to the speed V4 when moving in the Z-axis direction. In the electronic component mounting apparatus 10, the condition for decelerating from the speed V4 is a condition for further decelerating the moving speed of the nozzle from the speed V4 when moving in the Z-axis direction. The speed (fourth speed) V4 is a speed slower than the speed (second speed) V3 described above.

  The electronic component mounting apparatus 10 determines the nozzle movement pattern shown in FIG. 109 by determining the conditions for changing (decelerating) the nozzle movement speed in steps S544 and S546. FIG. 109 shows the relationship between the moving speed of the nozzle and time, that is, the moving speed of the nozzle at each time. The movement pattern based on the third speed reference shown in FIG. 109 is accelerated to the speed V1 when the nozzle starts to move to the mounting position (nozzle lowering), and then moves at the speed V1 until time t7. Thereafter, the nozzle starts decelerating at time t7 and decelerates to speed V4 at time t8. Here, the time t8 is a time when the distance between the lower end of the electronic component (that is, the lower end of the lead) and the substrate becomes a set distance. Specifically, this is the time when the lower end of the electronic component and the substrate are close to a certain distance. Thereafter, the nozzle moves at a constant speed until time t9, starts decelerating at time t9, and then stops.

  The electronic component mounting apparatus 10 moves the electronic component according to the movement pattern of FIG. 109, and as in the case of FIG. 105, until the electronic component approaches within a certain distance of the substrate at time t7 (that is, farther than the certain distance). Range), the electronic component can be moved at a speed (first speed) V1. After that, until the electronic component is mounted (mounted) on the board, that is, from when the electronic component approaches within a certain distance of the board until the lead is inserted into the insertion hole to complete the mounting (that is, within a certain distance). The electronic component can be moved at a speed (fourth speed) V4 that is slower than the speed V1. Thus, the electronic component can be moved quickly in a range where the substrate is not affected, and the electronic component can be moved slowly in a range where the substrate may be affected. As a result, the time required for mounting can be shortened while maintaining the accuracy of mounting on the substrate.

  The electronic component mounting apparatus 10 detects the timing of decelerating from the speed V4 based on the lead length, that is, determines the interval from time t8 to time t9, so that the lead can be stably read as described above. Can be inserted into the substrate. Further, the electronic component can be moved until the main body 82 and the substrate approach a certain distance.

  Further, in the case of a lead-type electronic component, the electronic component mounting apparatus 10 can adjust the pressure for pressing the main body of the electronic component against the substrate after the electronic component and the substrate are in contact with each other by adjusting the timing at time t9. . Thereby, a main body can be moved with respect to a board | substrate on different conditions from the mounting type electronic component which presses a terminal to a solder paste.

  Also, in the electronic component mounting apparatus 10, when the lead is formed and a larger sliding resistance occurs when the insertion hole is inserted, the moving speed when the lead is inserted into the insertion hole is a speed V4 that is slower than the speed V3. By doing so, the formed lead can be suitably inserted into the insertion hole. Thereby, the electronic component in which the lead is formed can be suitably mounted on the substrate.

  As shown in FIG. 100 to FIG. 109, the electronic component mounting apparatus 10 moves in the Z-axis direction according to the type of electronic component. By adjusting the pattern, the electronic component can be mounted on the substrate with a movement pattern corresponding to each electronic component. Furthermore, in the case of lead-type electronic components, the electronic components are mounted on the board with the movement pattern corresponding to each electronic component by adjusting the movement pattern in the Z-axis direction of the electronic component depending on whether it is formed or not. Can do.

The electronic component mounting apparatus 10 allows the movement speed V3 in the case of the lead-type electronic component to be slower than the movement speed V2 in the case of the mounted electronic component in the range in which the electronic component approaches the vicinity of the substrate. The lead type electronic component can be more reliably mounted on the substrate.
In addition, the electronic component mounting apparatus 10 moves the electronic component whose lead is formed at a moving speed in a range where the electronic component is close to the vicinity of the board than the moving speed V3 in the case of the electronic component where the lead is not formed. By lowering the speed V4, the formed lead can be more reliably inserted into the insertion hole. Thereby, the probability of mounting electronic components can be further increased.

  In addition, when mounting the lead wire electronic component as described above, the lead can be more suitably inserted into the insertion hole by setting the movement pattern based on the lead wire length, with higher accuracy. In addition, the electronic component can be efficiently mounted on the substrate.

  Further, as shown in FIG. 100, the electronic component mounting apparatus 10 preferably changes the speed reference according to the type of electronic component and calculates with a movement pattern corresponding to the type, but is not limited thereto. In the case where the electronic component mounting apparatus 10 is configured to mount only the lead type electronic component, the electronic component mounting apparatus 10 may execute the process of step S504 every time. Also, the processing of step S506, step S508, and step S510 of FIG. 100 may be performed repeatedly. Moreover, although the electronic component mounting apparatus 10 showed the relationship between speed and time as a movement pattern, the movement pattern may be calculated based on the relationship between speed and position and speed and distance.

  Next, an example of a processing operation when electronic components are mounted will be described with reference to FIG. FIG. 110 is a flowchart illustrating an example of the operation of the electronic component mounting apparatus. The electronic component mounting apparatus 10 executes the processing shown in FIG. 110 every time the electronic component is moved by the nozzle of the head. Note that the processing in FIG. 110 is basically processing when both lead-type electronic components and mounted electronic components are mounted on a substrate as electronic components. The electronic component mounting apparatus 10 identifies an electronic component to be held in step S910, and determines whether the component to be held is a lead type electronic component in step S912.

  If it is determined in step S912 that the electronic component mounting apparatus 10 is a lead type electronic component (Yes), the electronic component mounting apparatus 10 holds the lead type electronic component of the electronic component supply apparatus with a nozzle in step S914. That is, the electronic component mounting apparatus 10 holds the lead-type electronic component supplied to the holding position (second holding position) of the electronic component supply apparatuses 100, 402, 404, 406, and the like with the nozzle. When the electronic component mounting apparatus 10 holds the lead type electronic component with the nozzle in step S914, in step S916, the lead of the lead type electronic component is inserted into the insertion hole and mounted on the substrate.

  If it is determined in step S912 that the electronic component mounting apparatus 10 is not a lead-type electronic component (No), in step S917, the electronic component mounting apparatus 10 holds the mounted electronic component of the electronic component supply apparatus with a nozzle. That is, the electronic component mounting apparatus 10 holds the mounted electronic component supplied to the holding position (first holding position) of the electronic component supply apparatus 100a and the like with the nozzle. After holding the mountable electronic component with the nozzle in step S917, the electronic component mounting apparatus 10 mounts the mountable electronic component on the substrate in step S918. That is, the electronic component mounting apparatus 10 mounts the mountable electronic component on the substrate without inserting it into the insertion hole.

  When the electronic component mounting apparatus 10 executes the process of step S916 or step S918, that is, when the electronic component is mounted, the electronic component mounting apparatus 10 determines in step S919 whether or not all the electronic components have been mounted. If the electronic component mounting apparatus 10 determines in step S919 that the mounting is not completed (No), the electronic component mounting apparatus 10 proceeds to step S910, specifies the electronic component to be mounted next, and performs the above processing on the specified electronic component. Execute. If the electronic component mounting apparatus 10 determines that the mounting is completed (Yes) in step S919, the electronic component mounting apparatus 10 ends the process.

  As shown in FIG. 110, the electronic component mounting apparatus 10 can mount the mountable electronic component and the lead type electronic component on the substrate with one head. Furthermore, the electronic component mounting apparatus 10 can mount both a mountable electronic component and a leaded electronic component with the same nozzle. Here, the transmission component mounting apparatus 10 can be transported and mounted by the same nozzle as the mounted electronic component by holding (sucking or gripping) the main body of the lead type electronic component. In addition, the electronic component mounting apparatus 10 performs mounting with the same head or the same nozzle by determining whether the electronic component mounting device or the lead electronic component is inserted and switching between inserting and not inserting the lead into the insertion hole in accordance with each. Even in this case, it can be mounted on a substrate under conditions suitable for each electronic component. Thereby, it is possible to mount the mountable electronic component and the leaded electronic component without replacing the nozzle. Further, the mounting type electronic component and the lead type electronic component can be mixed and mounted without being separated, so that the mounting order is less restricted and the mounting efficiency can be further improved.

  Here, the electronic component mounting apparatus 10 can obtain the above effect more suitably by using the radial lead type electronic component supplied by the electronic component supply apparatus 100 as described above as the lead type electronic component. The electronic component mounting apparatus 10 holds a radial lead type electronic component whose lead has been cut to a predetermined length by the electronic component supply apparatus 100 with a nozzle. Is inserted into the insertion hole and mounted on the board. Thus, since the electronic component mounting apparatus 10 holds the main body of the electronic component, the length of the lead can be shortened. Furthermore, since the electronic component mounting apparatus 10 is configured to cut the lead before being transported and held by the tape body, the portion of the radial lead type electronic component lead that has been held by the tape to be transported is removed. It can be mounted on the substrate in a removed state. As a result, the lead of the radial lead type electronic component can be shortened and mounted on the substrate, and the electronic component can be mounted on the substrate in a stable state. Specifically, since the lead of the radial lead type electronic component can be shortened and mounted on the substrate, the vibration applied to the substrate due to the contact between the lead and the insertion hole when the substrate is mounted can be reduced. As a result, even if the radial lead type electronic component and the mounting type electronic component are mounted in the same process, the influence on each other's mounting can be reduced. In the same process, that is, the same head and the same nozzle are continuously mounted. Even in this case, both electronic components can be preferably mounted.

  Here, the electronic component mounting apparatus 10 of the above embodiment includes a bowl feeder assembly 90 using a bowl feeder as the component supply unit 14f, and a configuration including the radial feeder electronic component supply device 100 as the component supply unit 14r. However, it is not limited to this. The electronic component mounting apparatus 10 can have various combinations of component supply units. For example, the bowl feeder electronic component supply device may be installed in both the front and rear component supply units, or the radial feeder electronic component supply device may be installed in both the front and rear component supply units. . Further, as described above, the component supply unit may include an electronic component supply device (chip component feeder) 100a that supplies the mounted electronic component with the electronic component holding tape. Further, the electronic component supply device of one component supply unit of the front and rear may be all electronic component supply device (chip component feeder) 100a. That is, one of the front and rear component supply units supplies lead-type electronic components (electronic components inserted into the board), and the other supplies leadless electronic components (electronic components mounted on the board). It may be. The electronic component mounting apparatus can also use a so-called tray feeder as the electronic component supply apparatus. In addition, the electronic component mounting device supplies the holding position in the state where the lead of the axial type electronic component held on the tape as an electronic component supply device is cut out so as to be short under the substrate as described above and bent into a U-shape. An axial feeder can also be used. In this case, the electronic component mounting apparatus uses the nozzle to hold the axial electronic component main body at the holding position of the axial feeder, and then determines whether the lead interval is good or not, and inserts the axial electronic component that has been judged good. Insert into. The electronic component mounting apparatus 10 can be mounted on or inserted into a substrate by adsorbing or gripping the electronic component, regardless of the electronic component supplied by any electronic component supply device. In addition, the electronic component supply apparatus that supplies the lead-type electronic component nozzles the lead-type electronic component in the direction in which the main body is arranged on the upper side in the vertical direction of the lead, that is, in the direction in which the lead is arranged on the lower side in the vertical direction of the main body. To the holding position held by Here, the electronic component mounting apparatus 10 includes a component supply unit including a bowl feeder and other types of electronic component supply apparatuses, such as the radial feeder, the axial feeder, and the mountable electronic component tape, as in the present embodiment. It is preferable to arrange a component supply unit such as a feeder, a stick feeder, or a tray feeder on the front side rear side, which is a position facing the substrate conveying unit 12. As a result, it is possible to suppress the influence of vibration of the bowl feeder on other types of component supply units, so that the nozzle holding action for the electronic components supplied by the other types of electronic component supply devices at the holding position can be stabilized. Can be made.

  In the present embodiment, the component supply unit is described as two component supply units 14f and 14r, but the number is not limited. Further, the two component supply units 14f and 14r can be regarded as one component supply unit, and the component supply units 14f and 14r can be regarded as a first component supply unit and a second component supply unit, respectively. For example, as in the above embodiment, one component supply unit includes a bowl feeder (component supply unit 14f, first component supply unit) and a radial feeder (component supply unit 14r, second component supply unit). Can be considered. In this case, the first component supply unit and the second component supply unit are arranged at positions facing each other across the position where the substrate is arranged. Further, it can be considered that one component supply unit 14f includes a first component supply unit and a second component supply unit. For example, as described above, it can be considered that one component supply unit 14f includes a radial feeder (first component supply unit) and a chip component feeder (second component supply unit). Thus, the electronic component mounting apparatus 10 can be configured to include a plurality of types of electronic component supply apparatuses regardless of the combination.

  Here, as an electronic component supplied by the electronic component supply apparatus 100 which is a radial feeder, there are various radial lead type electronic components capable of holding a lead with a tape. The electronic component supply apparatus 100 can supply, for example, an aluminum electrolytic capacitor, an inductor, a ceramic capacitor, a film capacitor, and the like. In addition, electronic components supplied by the electronic component supply devices 402, 404, and 406, which are bowl feeders, include various lead-type electronic components of package components. The electronic component supply devices 402, 404, and 406 can supply, for example, a solid state relay, a DIP type electronic component, a SIP type electronic component, a connector, a transformer, and the like.

  Further, when the head 15 of this embodiment includes a plurality of nozzles so that more types of electronic components can be mounted by one head, the automatic nozzle changer (replacement in this embodiment) is performed. Each nozzle can be replaced with various suction nozzles and gripping nozzles during mounting production using a head holding operation realized by a combination of a nozzle holding mechanism and a head body. The electronic component mounting apparatus 10 is based on component conditions such as the size, weight, whether the upper surface of the component body has a suckable plane, and whether the component body can be gripped. A suction nozzle having an appropriate suction hole diameter or a gripping nozzle having a gripping member having an appropriate shape is designated for each part and stored in the production program. The electronic component mounting apparatus 10 switches the nozzle to be mounted on the head or determines the nozzle that holds the electronic component in the head based on the correspondence between the electronic component and the nozzle stored in the production program. .

  As a result, in the electronic component mounting apparatus 10, for example, when the electronic component held by the nozzle during board mounting is changed from the mounted electronic component to the lead electronic component, the nozzle and the lead electronic component that hold the mounted electronic component May be held by a nozzle different from the case where the nozzle is held by the same nozzle. When the nozzles are different, the electronic component mounting apparatus 10 automatically replaces the nozzles by the automatic nozzle replacement device when the electronic components to be mounted are changed during setup or during production. That is, when an electronic component to be mounted on a substrate during production is, for example, a mountable electronic component, a nozzle (suction nozzle or gripping nozzle) suitable for the electronic component is selected, and an electronic component supply apparatus that supplies the electronic component is selected. The nozzle is moved to the mounting type electronic component in the holding position to hold the electronic component and move to a predetermined position on the substrate, and the electronic component is continuously mounted while being controlled at the lowering speed. The electronic component mounting apparatus 10 determines whether the nozzles are the same or different when a predetermined number of electronic components have been mounted and the next electronic component to be mounted is changed to a lead-type electronic component. When it is determined that the nozzles are the same, the electronic component mounting apparatus 10 uses the same nozzle as the nozzle for the lead-type electronic component because it is not necessary to replace the nozzle. In addition, when it is determined that the nozzles are different, the electronic component mounting apparatus 10 uses the nozzle for the lead type electronic component as a nozzle for the lead type electronic component when there is a nozzle that can be used with the other nozzle mounted on the head. When there is no nozzle that can be used as a nozzle, the nozzle is automatically changed to the lead type electronic component nozzle automatically by the nozzle automatic changing device. When the electronic component mounting apparatus 10 prepares the nozzle for the lead type electronic component in this way, the electronic component mounting apparatus 10 that moves the head to move the nozzle to the holding position of the lead type electronic component supply apparatus A lead-type electronic component provided with a lead cut in advance to a predetermined length from an electronic component tape (electronic component holding tape) by a built-in cutting device (cut unit) by an electronic component supply device that supplies the lead-type electronic component Is set to the holding position. The electronic component mounting apparatus 10 holds and holds the lead-type electronic component by the nozzle, and moves to the substrate by determining the lead interval and determining the positional deviation by the detection means (laser recognition device 38). Switching control that sorts electronic parts to be inserted into the insertion hole (substrate hole) and corrects the positional deviation of the lead when inserting it into the insertion hole, and sequentially decelerates the descending speed when inserting it according to the cutting length of the lead While implementing.

  Further, when the head 15 includes a plurality of nozzles, it is sufficient that the head 15 includes at least one nozzle that can hold and mount a lead-type electronic component (insertion-type electronic component), and the configuration of the nozzle may be variously configured. Can do. For example, the head 15 may be a nozzle in which some of the nozzles hold lead-type electronic components and the remaining nozzles hold nozzles for mounting electronic components. In this case, the electronic component mounting apparatus performs mounting control for mounting the mounted electronic component on the board when the nozzle holds the mounted electronic component, and performs the mounting control for mounting the mounted electronic component on the substrate. Mounting control for inserting the electronic component into the insertion hole (substrate hole) is performed. Further, the head 15 may use all the nozzles as nozzles for holding lead-type electronic components. The electronic component mounting apparatus 10 holds and mounts an electronic component according to the type of electronic component when determining a suction nozzle (or a gripping nozzle for gripping) that attracts the electronic component to be mounted based on the production program. Determine the nozzle. In this way, the electronic component mounting apparatus 10 prepares a plurality of nozzles that can be mounted on a single head, operates the automatic nozzle changer during production according to a command based on the production program, and then selects the nozzle to be mounted on the head. By mounting / removing the nozzles in accordance with electronic components to be produced (electronic components to be mounted), the lead-type electronic components can be held and inserted into the substrate, and the mounted electronic components can be mounted on the substrate in sequence.

  Next, an example of an electronic component mounting system (mounting system) using the electronic component mounting apparatus described above will be described with reference to FIGS. 111 and 112. FIG. 111 is a schematic diagram showing a schematic configuration of an electronic component mounting system. An electronic component mounting system (hereinafter also referred to as “mounting system”) 1 illustrated in FIG. 111 includes a pattern forming device 2, a reflow processing device 4, transfer devices 6 and 7, and an electronic component mounting device 10. In the mounting system 1, each part is arranged so that the substrates are transported in the order of the pattern forming device 2, the transport device 6, the electronic component mounting device 10, the transport device 7, and the reflow processing device 4.

  The pattern forming apparatus 2 is an apparatus that forms a solder paste pattern on the surface of a substrate and fills the insertion hole of the substrate with the solder paste. The reflow device 4 heats the substrate to a predetermined temperature and temporarily melts the solder paste on the substrate, thereby bonding the substrate in contact with the solder paste and the electronic component. That is, the reflow device 4 is a lead-type electronic device in which a mounting-type electronic component mounted on a solder paste pattern formed on the surface of a substrate is bonded to the substrate with the pattern solder paste, and a lead is inserted into the insertion hole. The lead insertion hole of the component is bonded with the solder paste filled in the insertion hole.

  The transfer devices 6 and 7 are devices that transfer a substrate. The transport device 6 carries the substrate processed and carried out by the pattern forming device 2 into the electronic component mounting device 10. The transport device 7 carries the substrate processed and carried out by the electronic component mounting device 10 into the reflow processing device 4.

  As described above, the electronic component mounting apparatus 10 mounts electronic components on a substrate. Here, the electronic component mounting apparatus 10 can mount a lead-type electronic component as an electronic component. Moreover, the electronic component mounting apparatus 10 can also mount both a lead-type electronic component and a mountable electronic component as electronic components. The mounting system 1 is configured as described above.

  FIG. 112 is a flowchart illustrating an example of the operation of the electronic component mounting system. The mounting system 1 prints the solder paste on the substrate as step S960. That is, the mounting system 1 forms a solder paste pattern on the surface of the substrate by the pattern forming apparatus 2 in step S960 and fills the insertion hole with the solder paste. After the solder paste is printed on the board in step S960, the mounting system 1 carries the board into the electronic component mounting apparatus 10 by the transport device 6, and in step S962, the electronic component mounting apparatus 10 mounts the lead-type electronic component and the mounting type on the board. Mount electronic components. After mounting the electronic component on the substrate in step S962, the mounting system 1 carries the substrate on which the electronic component is mounted by the transport device 7 into the reflow processing device 4, executes reflow processing in step S964, and ends this processing. To do.

  As described above, the mounting system 1 mounts the lead type electronic component and the mountable electronic component by the electronic component mounting apparatus 10, so that both the lead type electronic component and the mountable electronic component can be processed by a single flow process. Can be fixed to. Thereby, the mounting system 1 can simplify the configuration of the production line.

  Further, by mounting the lead-type electronic component and the mount-type electronic component with the electronic component mounting apparatus 10, it is possible to mount the radial lead-type electronic component in a short state as described above. Thus, the mounting system 1 mounts the lead type electronic component and the mount type electronic component in the same process, and even if the lead type electronic component and the mount type electronic component are simultaneously reflowed, the electronic component is preferably mounted on the board. Can be adhered to. Thereby, the production efficiency of a board | substrate can be improved.

  In addition, the electronic component mounting system 1 fixes a conventionally performed component by temporarily inserting a lead inserted by filling or applying a solder paste into the insertion hole and temporarily fixing the lead to the insertion hole via the solder paste. For this reason, the component folding process on the back side of the substrate can be made unnecessary, so that the leads can be shortened, thereby eliminating the lead bending device provided on the back side of the substrate in the conventional mounting apparatus for board insertion. Further, a support pin for supporting a substrate used in a conventional electronic component mounting apparatus (chip mounter) can be arranged at an arbitrary position and can be inserted into the substrate mounting and insertion hole by the head.

  Note that the mounting system 1 illustrated in FIGS. 111 and 112 can obtain the above-described effects, and thus the mounting system including the electronic component mounting apparatus having a preferable configuration is not limited thereto. For example, the mounting system may include a plurality of electronic component mounting apparatuses 10.
