  Next, the operation of the component feeder 5 and the detailed functions of each part will be described with reference to FIGS. FIG. 7 shows a process of driving the cylinder 14 from the state shown in FIG. 4 to advance the drive engagement portion 5c by the drive coupling portion 14b. Here, the first cam plate 22 moves forward (arrow e), the cam follower 26b moves into the horizontal portion 25b of the cam groove 25, and the cam follower 27b is still in the horizontal portion 25b. At this time, the guide member 24 is positioned in the middle of the movement range of the cam groove 23, and the cylinder 14 is in a state of operating to the middle of the full stroke.

  Due to the movement of the horizontal portion 25b accompanying this operation, the first link member 26 is rotated about the pivot pin 26a, and the link member 30 and the cam block 52 connected to the first link member 26 are respectively pivotally supported. It moves forward (arrows f1, f2) by a movement amount (first stroke S1, second stroke S2; see FIG. 10) according to the lever ratio from the pin 26a. Here, the lever ratio of the connecting pin 26c and the cam follower 26d is 1: 2, and the movement amount (second stroke S2) of the cam block 52 is twice the movement amount (first stroke S1) of the link member 30. .

  As a result, the third cam plate 33 coupled to the link member 30 moves forward together with the fourth cam plate 35 (arrow g), and the cutting portion 37 disposed in the bent portion 35d moves through the first stroke S1. Just move forward. As a result, the cutting unit 37 moves from the predetermined standby position [P3] to the cutting position [P4]. Further, the cam block 52 advances together with the claw feed plate 51 of the feed claw drive unit 42 (see FIG. 10), and advances the feed members 54A and 54B provided on the claw feed plate 51 by the second stroke S2. As a result, the taping component series 6 mounted on the component mounting surface 20d moves to the delivery position [P1] to the component transport pallet 10 of the component transport mechanism 8 with the vertical posture in which the leads 7b are upright. Accordingly, the first cam plate 22, the first link member 26, the cam block 52, the feed claw drive unit 42, and the feed members 54A and 54B provided on the locking release plate 50 of the feed claw drive unit 42 are taping components. A component feeder that moves the ream 6 to the receiving position [P1] is configured. The feed members 54A and 54B have a feed claw 54a that engages with the lead 7b of the component 7 and moves in one direction.

  FIG. 8 shows a state where the drive coupling portion 14 b further protrudes from the state shown in FIG. 7 and the first cam plate 22 has advanced by the entire stroke allowed by the cam groove 23. Here, since the horizontal portion 25b maintains the same position, the third cam plate 33 and the cam block 52 are at the same position as in FIG. 7, but the cam follower 27b is located at the rear end portion 25c displaced in the height direction in the cam groove 25. Since the second link member 27 moves, the second link member 27 rotates counterclockwise around the pivot pin 27a (arrow i). As a result, the second cam plate 28 connected to the second link member 27 via the cam follower 27c retreats in the horizontal direction (arrow j), and with this movement, the two link members 31 both move to the second cam plate. It is displaced in a direction (arrow k) attracted to 28. This displacement acts so as to separate the two connecting pins 32b in the height direction (arrow l). Accordingly, the fourth cam plate 35 connected to the connection pin 32b similarly moves in the vertical direction, and the tape cutting operation is performed by the cutting part 37 disposed in the bent part 35d.

  The tape cutting operation by the cutting unit 37 will be described with reference to FIG. FIG. 9B shows the cutting portion 37 in the state shown in FIG. 7, that is, the second cam plate 28 does not advance and the fourth cam plate 35 is in the original position. In this state, the narrowing unit 60 is in a state where the first blade edge member 61 and the second blade edge member 62 are opened, and the tape 6 a is located between the first blade edge member 61 and the second blade edge member 62. From this state, the first cam plate 22 is further advanced as shown in FIG. 8, whereby the fourth cam plate 35 is moved in the direction of arrow n, and the tape cutting operation is executed.

  In other words, the cutting unit 37 constituted by the fixing unit 63 and the fixing pins 63a, 63b, and 63c disposed in the bent unit 35d delivers the tape 6a to the component conveying pallet 10 by cutting the tape 6a. The target component 7 has a function of separating. In addition, the first cam plate 22, the first link member 26, the link member 30, the third cam plate 33, and the fourth cam plate 35 are configured so that the cutting portion 37 is moved to a predetermined standby position [P3] and cutting position [P4]. ] Is configured to advance / retreat. In the present embodiment, the above-described component feeding section, cutting section, and advance / retreat section are driven by a cylinder 14 that is a reciprocating drive source. This makes it possible to perform all operations necessary for component supply with a single drive source, simplifying the mechanism and reducing equipment costs.

  Next, the displacement of the feeding member 54 in the component feeding operation and the displacement of the narrowing unit 60 in the tape cutting operation will be described with reference to FIG. FIG. 10A shows the state of the feeding members 54A and 54B and the narrowing unit 60 when the link mechanism disposed on the drive surface 20c is in the state shown in FIG. Here, illustration of the claw feed plate 51 (see FIG. 6) for advancing the feed members 54A and 54B is omitted. In this state, since the first cam plate 22 has not moved forward at all, the feed members 54A and 54B are in their original positions, and the lead 7b can be locked for feeding parts by the feed claws 54a. . The narrowing unit 60 is in the standby position [P3] with the first blade edge member 61 and the second blade edge member 62 opened.

  From this state, the first cam plate 22 is advanced to the state shown in FIG. 7, so that the narrowing unit 60 of the cutting portion 37 is advanced by the first stroke S1, as shown in FIG. 10B. It moves from the standby position [P3] to the cutting position [P4], and the feed members 54A and 54B advance by a second stroke that is twice the first stroke S1. That is, in the present embodiment, the moving strokes of the feeding members 54A and 54B constituting the component feeding unit are set to be larger than the advancing / retreating stroke of the advancing / retreating unit that moves the cutting unit 37 back and forth.

  With the advancement of the feed members 54A and 54B, the feed claw 54a moves forward by the second stroke S2 while locking and pushing out the lead 7b, and a delivery position [P1] for delivering the component 7 to the component transport pallet 10 To reach. By executing the above-described component feeding operation in a state where the component feeder 5 is aligned with the component conveying pallet 10, the lead 7b is pushed into the gripping portion 17 and gripped at the delivery position [P1] (see FIG. 3). .

  Further, by moving the first cam plate 22 forward from this state to the state shown in FIG. 8, the first blade edge member 61 and the second blade edge member 62 of the narrowing unit 60 are cut as shown in FIG. 10C. It moves in the closing direction at the position [P4], and the tape 6a for 71 parts at the tip is cut and separated into a cut tape piece 6a *. From this state, the cylinders 14 are reversely driven to retract the first cam plate 22 to the state shown in FIG. 4, so that the feeding members 54A and 54B and the narrowing unit 60 are in the state shown in FIG. Return to. Thereby, when the component conveyance pallet 10 moves, interference with the component currently hold | maintained at the component conveyance pallet 10 and the narrowing unit 60 can be prevented.

  Next, in the component feeding operation described above, a component breakage detection function for detecting that the component pieces 7 are sequentially separated from the taping component series 6 mounted on the component guide member 40 and the component breakage has occurred will be described. . 11 shows a horizontal section of the component detection unit 46 shown in FIG. 5. In the state shown in FIG. 11A, the component detection unit 46 is provided to extend in the horizontal direction from the component detection unit 46 to the taping component series 6. FIG. The lead contact portion 46d is in a position where it enters the gap between the adjacent leads 7b in the taping component series 6. In this state, the light shielding part 46c is positioned immediately above the photosensor 47 and shields the detection optical axis 47b.

  FIG. 11B shows a state in which the lead 7b is in contact with the lead contact portion 46d in the process of feeding the taping component series 6 (arrow q). At this time, when the lead contact portion 46d is pushed forward, the component detection portion 46 is pivotally displaced counterclockwise around the turning shaft 46b (arrow r), whereby the light shielding portion 46c is moved from directly above the photosensor 47. The light shielding state of the detection optical axis 47b is temporarily released. Here, when the taping component series 6 is mounted on the component feeder 5 and the component 7 is continuously supplied, the states of FIGS. 11A and 11B are repeated, whereby the photosensor 47 The detection signal output from is a signal pattern that regularly repeats on and off.

  On the other hand, when the component cut occurs and the taping component series 6 does not exist, the lead 7b does not come into contact with the lead contact portion 46d. A signal indicating that the detection optical axis 47b is in a light-shielding state is always output from the photosensor 47 while maintaining a stationary state. Then, when the control device 65 (FIG. 13) receives this signal, it is detected that the parts are out.

  Next, a feed claw free operation function provided in the component feeder 5 will be described with reference to FIG. In the process of supplying the plurality of parts 7 in the form of the taping part series 6, not all the parts 7 held by one taping part series 6 are consumed in one part insertion work, but still remaining parts When the work is finished in a state where there is, it is necessary to take out the taping component series 6 from the component feeder 5. In the feed claw free operation, in such a case, the feed members 54A and 54B are positioned so that the feed claw 54a is out of the row position of the leads 7b so that the feed claw 54a of the feed members 54A and 54B does not contact the lead 7b. Fix it.

  FIG. 12A shows a state in which the postures of the feed members 54A and 54B are fixed at positions where the feed claws 54a engage with the leads 7b. In a state where the lock release portion 44 is mounted on the feed claw drive portion 42, the compression spring 53 provided on the claw feed plate 51 abuts against the spring receiving portion 50c and urges forward (arrow s). When the fixing pin comes into contact with the rear end surface of the opening 50b, the relative position of the locking release plate 50 to the claw feed plate 51 is fixed.

  Further, the feed members 54A and 54B provided on the claw feed plate 51 are urged toward the lead 7b by the compression spring 56 on the feed claw 54a side with respect to the pin 55 (arrow t). , 54B are always in a posture in which the feed claw 54a is protruded into the gap between the leads 7b. Accordingly, in this state, the lead 7b is always locked by the feeding claw 54a, and the backward movement of the taping component series 6 is prohibited. At this time, the lock release claw 54 b is positioned in the opening 50 d provided in the lock release plate 50 without causing interference with the lock release plate 50.

  On the other hand, FIG. 12B shows a state in which the postures of the feeding members 54A and 54B are fixed so that the feeding claw 54a deviates from the row position of the lead 7b. For this purpose, first, the grip handle 50a and the lever handle 45 are both pulled out somewhat backward (arrow u) while the lever handle 45 is gripped and pushed down by the lock release portion 44 and rotated around the pivot pin 57. . Then, the locking notch 45a provided on the lever handle 45 is locked to the fixing pin.

  As a result, the locking release plate 50 moves backward relative to the claw feed plate 51 (arrows v and w), and the locking release claw 54b protruding into the opening 50d has an inner peripheral end surface in front of the opening 50d. Comes in contact with each other and moves the locking release claw 54b backward. As a result, the feed claw 54a located in the gap between the leads 7b is rotationally displaced to a position away from the row position of the leads 7b (arrow x). Therefore, in this state, the movement of the lead 7b is not hindered by the feeding claw 54a, and the backward movement of the taping component series 6 is allowed. In the above configuration, the lock release claw 54b provided in the feed members 54A and 54B, the opening 50d provided in the lock release plate 50, and the fixing pin that moves the lock release plate 50 backward to fix the position are An engagement release mechanism that releases the engagement of the claw 54a with the lead 7b is configured.

  Next, the configuration of the control system will be described with reference to FIG. In FIG. 13, the control device 65 controls the operations of the component supply mechanism 4, the component transport mechanism 8, the component insertion mechanism 12, the clinching mechanism 74, and the substrate transport mechanism 2. As a result, the component 7 to be inserted is supplied to the component transport pallet 10 mounted on the component transport mechanism 8, and is delivered to the component insertion mechanism 12 positioned on the substrate 3 by the component transport mechanism 8. The delivered component 7 is mounted on the substrate 3 by the component insertion mechanism 12, and the lead 7b is inserted into the insertion hole 3a. At this time, the control device 65 controls the board transport mechanism 2 so that the board 3 is carried in / out and the board 3 is positioned during component mounting.

  The control device 65 is connected to the storage unit 66, the display unit 67, and the input / output unit 68, and further receives a detection signal of the photosensor 47. The storage unit 66 stores data and programs necessary for executing the above-described component insertion operation. The display unit 67 is a display device such as a liquid crystal panel, and displays an operation screen when data or an operation command is input. The input / output unit 68 is an input device such as a keyboard or a touch panel, and performs input operations such as operation instructions and data. By continuously receiving the detection signal of the photosensor 47 by the control device 65, the presence or absence of the component 7 in the component feeder 5 is detected, and when it is determined that there is no component, that fact is displayed on the display unit 67. The

  Next, a component insertion method executed by the component insertion apparatus 1 having the above-described configuration will be described with reference to the drawings. First, prior to the start of component insertion work, the board 3 is transported by the board transport mechanism 2, and the board 3 is positioned and held at the component insertion work position (board transport process) (see FIG. 1). Next, the component 7 to be inserted is supplied in the form of a taping component series 6 in which both ends of the lead 7b are held by the tape 6a (component supply process).

  In this component supply process, the taping component series 6 is moved to a delivery position [P1] to the component transport mechanism 8 in a vertical posture in which the leads 7b are upright, and the cutting unit is moved forward and backward from the predetermined standby position to the cutting position. By cutting 6 a, the parts 7 to be delivered are separated from the taping parts series 6.

  Next, the individual components 7 delivered in the component supply process are transported onto the substrate 3 (component transport process). In this component transporting process, the lead 7b of the delivered vertical component 7 is gripped by the component transporting pallet 10 having gripping portions 17 capable of gripping at a plurality of locations. In the process of continuously executing the component insertion work, the belt 9 which is an endless annular band on which a plurality of component transport pallets 10 are mounted is pitch-fed at a predetermined pitch corresponding to the arrangement pitch p of the component feeders 5. As a result, the component conveying pallet 10 is aligned with the component feeder 5 (see FIG. 1).

  Next, the lead 7b of the component 7 received from the component transport mechanism 8 is molded and inserted in accordance with the pitch of the insertion holes 3a formed in the substrate 3 (component insertion step). This component insertion process will be described with reference to FIG. The component 7 held by the component conveying pallet 10 and conveyed to the delivery position [P2] (see FIG. 1) by the component conveying mechanism 8 is delivered to the component receiving unit 70 of the component inserting mechanism 12. As shown in FIG. 14A, the component receiving unit 70 includes a receiving mechanism in which a plurality of component holding heads 71 are concentrically arranged on a rotating member 70a that rotates by an index. The component holding head 71 includes a holding chuck 72 that can advance and retract in the outer diameter direction of the component receiving portion 70, and the holding chuck 72 clamps the lead 7b (or the cutting tape piece 6a *).

  When the component 7 is delivered from the component transport pallet 10 to the component insertion mechanism 12, the component insertion mechanism 12 is caused to perform a component receiving operation. That is, the component holding head 71 is first positioned with respect to the component conveying pallet 10, and then the component holding head 71 is advanced relative to the component conveying pallet 10, and the lead 7 b (or the cutting tape piece 6 a *) is clamped by the holding chuck 72. Then, the component holding head 71 is retracted to the original position. As a result, the component 7 held on the component transport pallet 10 is separated from the component transport pallet 10 against the gripping force of the leads 7 b by the gripping portion 17 and is delivered to the component holding head 71.

  Then, by rotating the rotating member 70 a by index (arrow y), the component holding head 71 that holds the component 7 sequentially moves to the delivery position to the insertion head 73. At the delivery position [P5], the component 7 to be inserted is delivered to the insertion head 73 as shown in FIG. Then, the lead 7b is bent at a predetermined position by the cutting mechanism and the bend mechanism provided in the insertion head 73 and is cut to remove the cutting tape piece 6a *. Thereby, the individual component 7 is processed into a shape into which the component can be inserted, as shown in FIG. Thereafter, the insertion head 73 is lowered to perform a component insertion operation, whereby the lead 7b is inserted into the insertion hole 3a formed in the substrate 3 as shown in FIG.

  Thereafter, a clinching operation is performed to bend the lead 7b that is inserted and protrudes toward the back side of the substrate 3 (a clinching step). That is, the clinching mechanism 74 is raised with respect to the lower surface of the substrate 3 (arrow z), and is bent into a predetermined shape by the clinching member provided in the clinching mechanism 74. As a result, the component 7 is fixed to the substrate 3 and the component insertion operation is completed.

  As described above, the component insertion device and the component insertion method shown in the present embodiment are used when the component 7 is supplied to the component insertion device 1 in the form of the taping component series 6 in which both ends of the lead 7b are held by the tape 6a. Then, the taping component series 6 is moved to the receiving position [P1] to the component conveying mechanism 8 in a vertical posture in which the lead 7b is upright, and then the cutting portion is advanced and retracted from the predetermined standby position [P3] to the cutting position [P4]. By cutting the tape 6a, the parts 7 to be delivered are separated from the taping parts series 6, and the parts conveying pallet 10 having the gripping parts 17 capable of gripping the leads 7b of the delivered parts 7 in the vertical posture at a plurality of locations. It is configured to grip. Thereby, the plane occupation area of the component conveyance pallet 10 can be made small, and the size reduction of an apparatus and reduction of equipment cost can be made compatible for an axial component.

  Further, in the present embodiment, the above-described component conveying pallet 10 is arranged at a predetermined interval in the vertical direction with respect to the pallet main body portion 10a that is attached to the endless annular belt that constitutes the pallet conveying portion and performs the pitch feeding operation. And at least one pair of gripping portions 17 capable of gripping and releasing the lead 7b of the component 7 in the vertical posture, and further gripping the gripping portion 17 in contact with the side surface of the lead 7b. A gripping piece 17b and a shaft support portion 17c that urges the gripping piece 17b in a direction perpendicular to the direction in which the component 7 is inserted into and withdrawn from the gripping portion 17 are provided, and the component feeder 5 is used at the receiving position [P1]. The component 7 is received by the component supply operation, and the gripping of the component 7 is released by the component receiving operation by the component insertion mechanism 12 at the delivery position [P2]. Those were Unishi. As a result, it is possible to achieve both the downsizing of the apparatus and the reduction of the equipment cost for the axial parts. Further, if a plurality of pairs of gripping portions 17 are provided, the parts can be transferred to a plurality of parts types. A pallet can be realized.

  Furthermore, in the present embodiment, the component feeder 5 that supplies the taping component series 6 to the component conveying mechanism 8 is used, and the component feeding unit 6 provided in the component insertion device 1 in a vertical posture with the leads 7b standing upright. A part feeding part that moves to the receiving position [P1] to the mechanism 8, a cutting part that separates the part 7 to be delivered from the taping part series 6 by cutting the tape 6a, and a predetermined waiting position [P3 ] And an advancing / retreating part for advancing / retreating between the cutting position [P4], and the component feeding part, the cutting part and the advancing / retreating part are driven by a cylinder 14 provided in the part inserting device 1.
