<Configuration of component mounting device>
1 shows a component mounting apparatus 10. The component mounting apparatus 10 is an apparatus for performing a mounting operation of components on a circuit board 12. The component mounting apparatus 10 includes an apparatus main body 20, a substrate transport and holding device 22, a component mounting device 24, a mark camera 26, a parts camera 28, a bulk component supply device 30, a component supply device 32, and a control device (see FIG. 13) 34. Examples of the circuit substrate 12 include a circuit board, a substrate having a three-dimensional structure, and the like, and examples of the circuit substrate include a printed wiring board, a printed circuit board, and the like.

The device body 20 is composed of a frame section 40 and a beam section 42 suspended on the frame section 40. The substrate transport and holding device 22 is disposed in the center of the frame section 40 in the front-rear direction, and has a transport device 50 and a clamp device 52. The transport device 50 is a device that transports the circuit substrate 12, and the clamp device 52 is a device that holds the circuit substrate 12. As a result, the substrate transport and holding device 22 transports the circuit substrate 12 and holds the circuit substrate 12 fixedly at a predetermined position. In the following description, the transport direction of the circuit substrate 12 is referred to as the X direction, the horizontal direction perpendicular to that direction is referred to as the Y direction, and the vertical direction is referred to as the Z direction. In other words, the width direction of the component mounting device 10 is the X direction, and the front-rear direction is the Y direction.

The component mounting device 24 is disposed on the beam section 42 and has two work heads 60, 62 and a work head moving device 64. As shown in FIG. 2, a suction nozzle 66 is provided on the lower end surface of each of the work heads 60, 62, and the suction nozzle 66 is used to suction and hold the component. The work head moving device 64 also has an X-direction moving device 68, a Y-direction moving device 70, and a Z-direction moving device 72. The two work heads 60, 62 are moved integrally to any position on the frame section 40 by the X-direction moving device 68 and the Y-direction moving device 70. The work heads 60, 62 are also detachably attached to sliders 74, 76, and the Z-direction moving device 72 moves the sliders 74, 76 individually in the vertical direction. In other words, the work heads 60, 62 are moved individually in the vertical direction by the Z-direction moving device 72.

The mark camera 26 is attached to the slider 74 facing downward, and is moved in the X, Y, and Z directions together with the work head 60. This allows the mark camera 26 to capture an image of any position on the frame section 40. The part camera 28 is disposed facing upward between the base material conveying and holding device 22 and the part supplying device 32 on the frame section 40, as shown in FIG. 1. This allows the part camera 28 to capture an image of the part held by the suction nozzle 66 of the work heads 60, 62.

The bulk parts supply device 30 is disposed at one end of the frame section 40 in the front-rear direction. The bulk parts supply device 32 is a device that aligns multiple parts that are scattered randomly and supplies the parts in the aligned state. In other words, it is a device that aligns multiple parts in any position into a specified position and supplies the parts in the specified position.

The component supply device 32 is disposed at the other end of the frame portion 40 in the front-rear direction. The component supply device 30 has a tray-type component supply device 78 and a feeder-type component supply device 80. The tray-type component supply device 78 is a device that supplies components placed on a tray. The feeder-type component supply device 80 is a device that supplies components using a tape feeder 82. The tape feeder 82 is described in detail below.

The feeder type component supply device 80 includes a tape feeder holder 83 fixedly provided at the other end of the frame portion 40. On the other hand, the tape feeder 82 includes a feeder body portion 84 as shown in FIG. 3. The tape feeder 82 is detachably attached to the tape feeder holder 83 at the feeder body portion 84. As shown in FIG. 4, the tape feeder 82 has a first delivery device 85, a cutting device 86, a second delivery device 88, and a driving device 90, and is a device that removes radial components from taped components and supplies the removed radial components. In the description of the tape feeder 82, the side where the second delivery device 88 of the tape feeder 82 is arranged may be referred to as the front side, and the opposite side to the front side may be referred to as the rear side.

As shown in FIG. 5, the taped component 100 is composed of multiple radial components 102 and a carrier tape 104. The radial component 102 includes a generally cylindrical main body 106 and two leads 108 extending from the bottom surface of the main body 106. The two leads 108 of the radial component 102 are taped to the carrier tape 104 at the lower end. In addition, multiple feed holes 110 are formed at equal pitches in the carrier tape 104. The multiple radial components 102 are taped to the carrier tape 104 at the same pitch as the formation pitch of the feed holes 110. However, although the multiple feed holes 110 in the carrier tape 104 are formed at equal pitches based on the standard, the attachment pitch of the leads of the radial components 102 to the carrier tape 104 is not accurate compared to the formation pitch of the feed holes 110.

The tape component 100 is installed in an upright state and extends along the upper surface of the feeder body 84 in order to compact the size of the tape feeder 82 in the width direction. More specifically, a groove 112 is formed on the upper surface of the feeder body 84 in the direction in which the tape feeder 82 extends, that is, along the Y direction, as shown in FIG. 4. The carrier tape 104 of the tape component 100 is accommodated in the groove 112 in an upright state, and the radial component 102 taped to the carrier tape 104 extends from the groove 112. The upright state of the tape component 100 means that the carrier tape 104 and the upper surface of the tape feeder 82 intersect at roughly right angles, and the lead 108 taped to the carrier tape 104 extends in the vertical direction. In this way, the tape component 100 is installed in an upright state, making it possible to narrow the width of the tape feeder 82.

The first delivery device 85 is disposed below the groove 112 in which the carrier tape 104 of the taped component 100 is housed. As shown in FIG. 6, the first delivery device 85 includes a holding block 120, a pair of claw members 122, an abutment block 124, a transmission rod 126, a spring 128, and a swinging mechanism 130. Note that FIG. 6 is a view in which the taped component 100 has been removed from FIG. 5.

The holding block 120 is held inside the feeder main body 84 so as to be slidable in the front-rear direction. A recess is formed on the upper surface of the holding block 120, and a pair of claw members 122 are held in the recess so as to be swingable in the front-rear direction. The tip of the claw member 122 protrudes a predetermined amount from the side surface of the holding block 120, and the tip of the claw member 122 engages with the feed hole 110 of the carrier tape 104 of the tape component 100. In addition, the tip of the claw member 122 retreats toward the inside of the holding block 120 as the claw member 122 swings, and at that time, the engagement of the claw member 122 with the feed hole 110 is released. In addition, an abutment block 124 is fixed to the lower end surface of the holding block 120. Furthermore, a transmission rod 126 is fixed to the rear end surface in the Y direction of the holding block 120 so as to extend in the Y direction.

A rod-side stopper 132 is disposed on the outer circumferential surface of the transmission rod 126, and a spring 128 is disposed in a compressed state between the rod-side stopper 132 and a main body-side stopper (not shown) formed on the feeder main body 84. As a result, the transmission rod 126 is biased forward together with the holding block 120 and the abutment block 124 by the elastic force of the spring 128.

The rocking mechanism 130 is a mechanism for rocking the pair of claw members 122, and rocks the claw members 122 in a direction in which their tips protrude from the holding block 120 when the holding block 120 moves forward a predetermined amount. After the holding block 120 has moved forward a predetermined amount, and when the holding block 120 is moving backward, the rocking mechanism 130 rocks the claw members 122 in a direction in which their tips retract into the inside of the holding block 120.

With this structure, when the holding block 120 moves forward a predetermined amount due to the elastic force of the spring 128, the taped component 100 is sent forward with the claw member 122 engaged with the feed hole 110 of the carrier tape 104. Then, after the holding block 120 moves forward a predetermined amount, and when the holding block 120 moves backward against the elastic force of the spring 128, the engagement of the claw member 122 with the feed hole 110 of the carrier tape 104 is released. As a result, after the taped component 100 has been sent forward a predetermined amount, the holding block 120 and the like are returned to their original positions.

The cutting device 86 is disposed in front of the first delivery device 85, that is, downstream of the delivery direction of the taped component 100. As shown in Figs. 7 and 8, the cutting device 86 includes a fixed member 140, a swinging member 142, and a roller 143. The fixed member 140 and the swinging member 142 are arranged side by side in the X direction, sandwiching the taped component 100 delivered by the first delivery device 85. The fixed member 140 is fixedly arranged facing one side of the taped component 100, and the swinging member 142 is swingably arranged facing the other side of the taped component 100. The roller 143 is rotatably held by a shaft (not shown) extending in the vertical direction at the lower end surface of the swinging member 142.

More specifically, as shown in FIG. 9, the fixed member 140 includes a fixed-side cutter holding portion 144. A protrusion 146 that protrudes toward the tape component 100 is formed at the upper end of the fixed-side cutter holding portion 144. The surface of the protrusion 146 that faces the tape component 100 is a fixed-side flat surface 148, and the lower edge of the fixed-side flat surface 148 is the fixed-side cutter 150.

The oscillating member 142 includes an oscillating body 152, a movable cutter holder 154, a lead holder 156, and a positioning plate 158. The oscillating body 152 is arranged in an orientation extending in the vertical direction, and is held oscillably on a shaft 159 arranged to extend in the Y direction. The movable cutter holder 154 is generally L-shaped, and is fixed to the upper end of the oscillating body 152 with its tip facing the tape component 100. The tip of the movable cutter holder 154 is the oscillating cutter 162. The fixed cutter 150 of the fixed member 140 and the oscillating cutter 162 of the oscillating member 142 face each other with the lead 108 taped to the carrier tape 104 of the tape component 100 sandwiched between them.

The lead holding portion 156 is arranged in a vertically extending position overlapping the oscillating body portion 152, and is held by the shaft 159 so as to be able to swing. The lead holding portion 156 is biased toward the oscillating body portion 152 by an elastic member (not shown). Therefore, the lead holding portion 156 swings together with the oscillating body portion 152. The upper end of the lead holding portion 156 is generally L-shaped, and the tip of the L-shape is located above the oscillating side cutter 162 fixed to the upper surface of the movable side cutter holding portion 154. The tip of the L-shape of the lead holding portion 156 faces the taping component 100. The surface of the lead holding portion 156 facing the taping component 100 is the oscillating side flat surface 166. The swing-side flat surface 166 and the fixed-side flat surface 148 of the fixed member 140 face each other with the lead 108 taped to the carrier tape 104 of the tape-forming component 100 sandwiched between them. When the lead holding portion 156 swings together with the swing-side main body portion 152, the swing-side flat surface 166 protrudes toward the tape-forming component 100 beyond the cutting edge of the swing-side cutter 162.

A positioning plate 158 is fixed to the upper end surface of the lead holding portion 156. The edge of the positioning plate 158 protrudes toward the tape component 100 side beyond the swing-side flat surface 166 of the lead holding portion 156, and a pair of notches 160 (see FIG. 6) are formed on the edge. The pair of notches 160 are shaped according to the wire diameter and pitch of the pair of leads 108 of the radial component 102 of the tape component 100.

With this structure, the cutting device 86 cuts the leads 108 taped to the carrier tape 104 as the swinging member 142 swings, and separates the radial component 102 from the carrier tape 104. More specifically, the swinging member 142 swings in a direction that brings its upper end closer to the taped component 100. At this time, the pair of leads 108 taped to the carrier tape 104 enters and is positioned inside the pair of notches 160 of the positioning plate 158. Then, as shown in FIG. 10, the pair of leads 108 are sandwiched between the swinging side flat surface 166 of the swinging member 142 and the fixed side flat surface 148 of the fixed member 140. As a result, the radial component 102 having the pair of leads 108 is held in a predetermined position.

Next, when the oscillating member 142 is further oscillated, the lead holding portion 156 is restricted from further oscillation by the contact of the oscillating side flat surface 166 with the fixed side flat surface 148, but the oscillating main body portion 152 oscillates further as shown in FIG. 11. At this time, the oscillating side cutter 162 of the movable side cutter holding portion 154 fixed to the oscillating main body portion 152 approaches the fixed side cutter 150 of the fixed member 140, and the pair of leads 108 sandwiched between the oscillating side flat surface 166 and the fixed side flat surface 148 are cut by the oscillating side cutter 162 and the fixed side cutter 150. As a result, the radial part 102 is separated from the carrier tape 104, and the radial part 102 is supplied at the position positioned by the positioning plate 158. That is, the lead 108 of the radial part 102 is positioned by the notch 160 of the positioning plate 158 and is sandwiched between the oscillating side flat surface 166 and the fixed side flat surface 148 so that it is supplied without falling over. Note that in the above description, the lead 108 of the radial part 102 is sandwiched between the oscillating side flat surface 166 and the fixed side flat surface 148 so that it is supplied without falling over, but the lead 108 of the radial part 102 may be cut while being held by a part holder such as the suction nozzle 66.

As shown in Figures 7 and 8, the second delivery device 88 is disposed in front of the cutting device 86, that is, downstream in the delivery direction of the taped component 100, and delivers the carrier tape 104 (hereinafter, sometimes referred to as "discharged tape") in a state in which the radial component 102 has been separated from the taped component 100 by the cutting device 86, toward the rear of the tape feeder 82. In more detail, as shown in Figure 12, the second delivery device 88 includes a rotating shaft 170, an internal roller 172, a first external roller 174, a second external roller 176, a roller cover 178, a pressing plate 180, a one-way clutch 182, a clutch cover 184, and a cam follower 186.

The rotating shaft 170 is held by the feeder body 84 in a vertically extending position so that it can rotate on its own axis. An internal roller 172 is fitted to the outer circumferential surface of the rotating shaft 170, generally at the center in the axial direction. Furthermore, a first external roller 174 is fitted to the outer circumferential surface of the internal roller 172 at the upper end in the axial direction, and a second external roller 176 is fitted to the outer circumferential surface of the internal roller 172 at the lower end in the axial direction. The first external roller 174 and the second external roller 176 are fitted to the outer circumferential surface of the internal roller 172, separated by a predetermined distance in the axial direction. In addition, a plurality of protrusions 188 are formed at equal pitches on the outer circumferential surfaces of the first external roller 174 and the second external roller 176. The pitch of the protrusions 188 is the same as the pitch of the leads 108 taped to the carrier tape 104. Then, the carrier tape 104 in which the radial components 102 have been separated from the tape component 100 by the cutting device 86, i.e., the discharge tape, is wound around the outer circumferential surfaces of the first external roller 174 and the second external roller 176. The discharge tape has the tips of the leads 108 remaining on it due to their cutting, and the arrangement pitch of the remaining leads is not accurate as described above. Taking into account the influence of the remaining leads that are not arranged at equal pitch, a plurality of protrusions 188 are formed on the outer circumferential surfaces of the first external roller 174 and the second external roller 176, and the discharge tape is wound around the outer circumferential surfaces of the first external roller 174 and the second external roller 176.

As shown in Figs. 7 and 8, the roller cover 178 is a plate-shaped member curved into a generally U-shape and is arranged to surround the first external roller 174 and the second external roller 176. The roller cover 178 is arranged in a state spaced apart from the outer circumferential surfaces of the first external roller 174 and the second external roller 176. The pressing plate 180 is a tape-shaped leaf spring, one end of which is fixed to the outer circumferential surface of the roller cover 178. The roller cover 178 has a slit 190 that is wider than the width of the pressing plate 180, and the pressing plate 180 is inserted into the roller cover 178 through the slit 190. The pressing plate 180 inserted into the roller cover 178 faces the outer circumferential surface of the lower end of the first external roller 174 and the outer circumferential surface of the upper end of the second external roller 176.

The roller cover 178 also has a hook hole 192 formed next to the slit 190, and the other end of the presser plate 180 is hooked into the hook hole 192. This causes the presser plate 180 to be urged toward the outer circumferential surfaces of the first external roller 174 and the second external roller 176 by its elastic force. In other words, the discharge tape wound around the outer circumferential surfaces of the first external roller 174 and the second external roller 176 is pressed against the outer circumferential surfaces of the first external roller 174 and the second external roller 176 by the elastic force of the presser plate 180.

A one-way clutch 182 is fitted to the lower end of the outer circumferential surface of the rotating shaft 170. A clutch cover 184 is fitted to the outer circumferential surface of the one-way clutch 182. The one-way clutch 182 can be of a sprag type or a cam type. For example, the sprag type one-way clutch 182 includes an annular inner race (not shown), an outer race fitted to the inner race, and sprags arranged between the inner race and the outer race. When the outer race rotates in one direction, the sprags mesh with the inner race and the outer race, and the inner race rotates together with the outer race. On the other hand, when the outer race rotates in the other direction, the sprags are released, and only the outer race rotates, and the inner race does not rotate. A torsion spring 196 is connected to the outer race, and the outer race rotates in the other direction due to the elastic force of the torsion spring 196. In other words, when the outer race rotates due to the elastic force of the torsion spring 196, the inner race does not rotate. On the other hand, when the outer race rotates against the elastic force of the torsion spring 196, the inner race rotates together with the outer race.

In the one-way clutch 182 with the above structure, the inner race is fitted onto the outer peripheral surface of the rotating shaft 170 and is connected to the rotating shaft 170. Meanwhile, a roller-shaped cam follower 186 is attached to the lower end surface of the outer race. The cam follower 186 is rotatable around an axis that extends in the vertical direction.

As shown in FIG. 6, the drive device 90 includes a transmission rod 200, a stopper 202, a first plate cam 204, a second plate cam 206, and a cylinder (see FIG. 13) 208. The transmission rod 200 is disposed below the first sending device 85, and is held by the feeder main body 84 in a state parallel to the transmission rod 126 of the first sending device 85 so as to be slidable in the front-rear direction. A cylinder 208 is connected to the rear end of the transmission rod 200. As a result, the transmission rod 200 slides in the front-rear direction as the cylinder 208 operates.

The stopper 202 is fitted onto the outer circumferential surface of the transmission rod 200. The stopper 202 extends upward, and the upper end of the stopper 202 is located in front of the abutment block 124 of the first delivery device 85. As a result, in the first delivery device 85, the abutment block 124, which is biased forward by the elastic force of the spring 128, abuts against the stopper 202, and the forward movement of the abutment block 124, i.e., the forward movement of the holding block 120, is restricted by the stopper 202.

The first plate cam 204 has a longitudinal shape and is fixed to the front end of the transmission rod 200 so as to extend in the front-rear direction. The first plate cam 204 is composed of a first part 210 of a predetermined thickness, a second part 212 having a plate thickness greater than that of the first part 210, and a third part 214 connecting the first part 210 and the second part 212 with a smooth surface, and the second part 212 is fixed to the front end of the transmission rod 200. The first plate cam 204 also extends downward from the cutting device 86, and one surface of the first plate cam 204 faces the roller 143 of the cutting device 86. The rocking member 142 of the cutting device 86 is biased by an elastic member (not shown) in a direction in which the roller 143 approaches the first plate cam 204. As a result, the roller 143 is in close contact with one surface of the first plate cam 204.

The second plate cam 206 has a longitudinal shape and is fixed to the front end of the first plate cam 204 so as to extend in the front-rear direction. The second plate cam 206 extends below the second sending device 88, and the front end face of the second plate cam 206 faces the cam follower 186 of the second sending device 88. The outer race of the one-way clutch 182 to which the cam follower 186 is fixed is biased by a torsion spring (see FIG. 12) 196 in a direction in which the cam follower 186 approaches the front end face of the second plate cam 206. As a result, the cam follower 186 is in close contact with the front end face of the second plate cam 206.

As shown in FIG. 13, the control device 34 includes a controller 220, a plurality of drive circuits 222, and an image processing device 226. The plurality of drive circuits 222 are connected to the above-mentioned conveying device 50, clamping device 52, working heads 60 and 62, working head moving device 64, cylinder 208, and bulk part supplying device 32. The controller 220 includes a CPU, ROM, RAM, etc., and is mainly a computer, and is connected to the plurality of drive circuits 222. As a result, the operation of the substrate conveying and holding device 22, the part mounting device 24, etc. is controlled by the controller 220. The controller 220 is also connected to the image processing device 226. The image processing device 226 processes image data obtained by the mark camera 26 and the part camera 28, and the controller 220 acquires various information from the image data.

<Tape feeder operation>
With the above-mentioned structure, in the tape feeder 82, the cylinder 208 is operated to slide the transmission rod 200 in the forward and backward directions, and the first delivery device 85, the cutting device 86, and the second delivery device 88 are linked and operated as one unit, thereby delivering the tape-formed component 100, separating the radial component 102 from the tape-formed component 100, and delivering the discharged tape. Specifically, the cylinder 208 is operated to slide the transmission rod 200 forward, and the stopper 202 also slides forward. At this time, the abutment block 124 of the first delivery device 85 abutting against the stopper 202 is biased forward by the elastic force of the spring 128, and slides forward together with the stopper 202. The holding block 120 that holds the claw member 122 also slides forward together with the abutment block 124. As described above, the claw member 122 engages with the feed hole 110 of the tape-formed component 100 when it slides forward a predetermined amount. Therefore, as the claw members 122 slide forward, a predetermined amount of the tape component 100 is fed forward.

When the transmission rod 200 slides forward due to the operation of the cylinder 208, the first plate cam 204 and the second plate cam 206 also slide forward. At this time, the roller 143 of the cutting device 86, which is in close contact with the first plate cam 204, and the cam follower 186 of the second sending device 88, which is in close contact with the second plate cam 206, move, so that the cutting device 86 and the second sending device 88 work together and operate as one unit. In more detail, before the transmission rod 200 slides forward, as shown in FIG. 14, the roller 143 is in close contact with the first part 210 of the first plate cam 204, and the cam follower 186 is in close contact with the front end surface of the second plate cam 206. The positions of the first plate cam 204 and the second plate cam 206 shown in FIG. 14 may be referred to as the neutral position.

When the transmission rod 200 slides forward due to the operation of the cylinder 208, the first plate cam 204 and the second plate cam 206 slide forward from the neutral position. At this time, as shown in FIG. 15, the roller 143 is in close contact with the first part 210 of the first plate cam 204, and the swinging member 142 connected to the roller 143 does not swing. Meanwhile, the cam follower 186 moves forward as the second plate cam 206 slides. As the cam follower 186 moves, the outer race of the one-way clutch 182 rotates counterclockwise against the elastic force of the torsion spring 196 (see FIG. 12). When the outer race rotates against the elastic force of the torsion spring 196, the inner race also rotates together with the outer race, as described above. Therefore, as shown in FIG. 15, when the cam follower 186 moves, the rotating shaft 170 (see FIG. 12) of the second delivery device 88 rotates, and the delivery direction of the discharged tape wound around the first external roller 174 and the second external roller 176 is changed by 180 degrees and delivered backward.

That is, the discharged tape, which is the radial part 102 separated from the taped part 100 by the cutting device 86, is wound around the outer circumferential surface of the first external roller 174 and the second external roller 176 as the rotating shaft 170 rotates. The discharged tape wound around the outer circumferential surface of the first external roller 174 and the second external roller 176 is then turned 180 degrees by the first external roller 174 and the second external roller 176 and sent out toward the rear. As a result, even if the discharged tape is a relatively hard tape such as craft tape, it is appropriately sent out toward the rear. The discharged tape sent out toward the rear is sent out to the rear end of the tape feeder 82. The discharged tape is then discharged from the rear end of the tape discharge section 230 (see FIG. 3) disposed at the rear end of the tape feeder 82.

At this time, in the second delivery device 88, the discharge tape is pressed against the outer circumferential surfaces of the first external roller 174 and the second external roller 176 by the elastic force of the pressure plate 180, so slippage, misalignment, etc. of the discharge tape is suppressed. In addition, the lower end of the lead 108 remains on the discharge tape in a state in which the radial component 102 has been separated from the tape component 100, and multiple protrusions 188 are formed along the circumferential direction on the outer circumferential surfaces of the first external roller 174 and the second external roller 176. Therefore, the lead 108 remaining on the discharge tape enters between two adjacent protrusions 188, suppressing slippage, misalignment, etc. of the discharge tape. In this way, proper delivery of the discharge tape is ensured by suppressing slippage, misalignment, etc. of the discharge tape.

When the transmission rod 200 slides further forward due to the operation of the cylinder 208, the first plate cam 204 and the second plate cam 206 also slide further forward as shown in FIG. 16. At this time, the roller 143 is in close contact with the first part 210 of the first plate cam 204, and the swinging member 142 connected to the roller 143 does not swing. Meanwhile, the cam follower 186 moves forward as the second plate cam 206 slides, and the outer race of the one-way clutch 182 rotates, causing the discharged tape to be sent out rearward. However, since the cam follower 186 moves along the circumferential direction of the outer race of the one-way clutch 182, it deviates from the orbit of the second plate cam 206.

In this way, when the cam follower 186 deviates from the orbit of the second plate cam 206, the cam follower 186 comes into close contact with the side of the second plate cam 206, rather than the front end face of the second plate cam 206. This stops the forward movement of the cam follower 186, and the rotation of the outer race, i.e., the rotation of the rotating shaft 170, also stops. In other words, in the second delivery device 88, the cam follower 186 shown in FIG. 14 moves to the cam follower 186 shown in FIG. 16, and the rotating shaft 170 rotates according to the movement distance of the cam follower 186, and the discharged tape is delivered rearward.

Before the cylinder 208 is operated, that is, when the cam follower 186 is in close contact with the front end surface of the second plate cam 206 (see FIG. 14) in the neutral position, in the first sending device 85, the claw member 122 is engaged with the feed hole 110 of the taped component 100. Also, as shown in FIG. 16, when the contact surface of the cam follower 186 with the second plate cam 206 moves from the front end surface to the side surface, in the first sending device 85, the engagement of the claw member 122 with the feed hole 110 of the taped component 100 is released. Therefore, at the timing when the taped component 100 is sent forward in the first sending device 85, the discharged tape is turned 180 degrees in the second sending device 88 and sent backward. In other words, the first sending device 85 and the second sending device 88 operate in synchronization, and the taped component 100 and the discharged tape are sent out. This makes it possible to properly feed the discharged tape between the first delivery device 85 and the second delivery device 88 without causing slack in the discharged tape or excessive tension on the discharged tape.

When the transmission rod 200 slides further forward due to the operation of the cylinder 208, the first plate cam 204 and the second plate cam 206 also slide further forward as shown in FIG. 17. At this time, the cam follower 186 is in close contact with the side of the second plate cam 206 and does not move forward. Therefore, the rotating shaft 170 does not rotate and the discharge of the discharged tape is maintained in a stopped state. Meanwhile, the contact surface of the roller 143 with the first plate cam 204 moves from the first part 210 to the third part 214, and the roller 143 moves in a direction away from the first plate cam 204. As a result, in the cutting device 86, the swinging member 142 swings and its upper end approaches the tape forming component 100.

When the transmission rod 200 slides further forward due to the operation of the cylinder 208, the first plate cam 204 and the second plate cam 206 also slide further forward as shown in FIG. 18. At this time, the cam follower 186 is in close contact with the side of the second plate cam 206 and does not move forward, so the delivery of the carrier tape 104 is maintained in a stopped state. Meanwhile, the contact surface of the roller 143 with the first plate cam 204 moves from the third part 214 to the second part 212, and the roller 143 moves further in a direction away from the first plate cam 204. At this time, in the cutting device 86, the swinging member 142 swings further, and as described above, the pair of leads 108 taped to the carrier tape 104 are sandwiched between the fixed side flat surface 148 and the swinging side flat surface 166, and the pair of leads 108 are cut by the fixed side cutter 150 and the swinging side cutter 162. In other words, while the first delivery device 85 stops delivering the taped component 100 and the second delivery device 88 stops delivering the carrier tape 104, the cutting device 86 holds a pair of leads 108 taped to the carrier tape 104 and cuts the pair of leads 108.

When the first plate cam 204 and the second plate cam 206 slide to the position shown in FIG. 18, the cylinder 208 operates to slide the transmission rod 200 backward, and the first plate cam 204 and the second plate cam 206 also slide backward and return to the neutral position. At this time, the roller 143 is kept in close contact with the first plate cam 204 and the cam follower 186 is kept in close contact with the second plate cam 206 by elastic force. Therefore, in the cutting device 86, the swinging member 142 swings in a direction that separates its upper end from the taping component 100. In the second delivery device 88, the outer race of the one-way clutch 182 rotates clockwise. However, since the outer race rotates clockwise due to the elastic force of the torsion spring 196, the inner race does not rotate together with the outer race. This prevents the rotation shaft 170 from rotating when the second plate cam 206 slides backward, and prevents the discharged tape from being sent back in the opposite direction.

When the transmission rod 200 is slid backward by the operation of the cylinder 208, the stopper 202 slides backward together with the transmission rod 200, as shown in FIG. 6. At this time, in the first delivery device 85, the abutment block 124 is pushed backward by the stopper 202 and slides backward against the elastic force of the spring 128. Then, together with the abutment block 124, the holding block 120 also slides backward. Note that when the holding block 120 slides backward, the engagement of the claw member 122 with the feed hole 110 of the taped component 100 is released, so that the taped component 100 is prevented from being sent back in the opposite direction due to the sliding of the holding block 120 backward. Then, when the holding block 120 slides to the rear end position, the claw member 122 engages with the feed hole 110 of the taped component 100.

In this way, in the tape feeder 82, the first feeding device 85, the cutting device 86, and the second feeding device 88 are linked and operate as a unit by the operation of the cylinder 208. In other words, the cylinder 208 is shared as a drive source for the first feeding device 85, the cutting device 86, and the second feeding device 88. This makes it possible to minimize the number of drive sources, and to reduce the installation space for the drive sources, the costs required for the drive sources, etc.

In addition, in the tape feeder 82, the discharged tape is sent backward by the second delivery device 88, but in the conventional tape feeder, a mechanism is provided to cut the discharged tape after the radial part 102 is separated from the taped part 100 by the cutting device 86. In such a case, a space is required to install the mechanism for cutting the discharged tape, and the tape feeder 82 cannot be made compact. In addition, in a tape feeder that cuts the discharged tape, a path or the like must be created to discharge the cut discharged tape, and there is a risk that the vertical dimension of the tape feeder will increase. On the other hand, in the tape feeder 82 of the present invention, as shown in FIG. 3, it is necessary to suppress the vertical dimension of the feeder main body 84 for design reasons. For this reason, by adopting the second delivery device 88, it is possible to suppress the vertical dimension of the feeder main body 84.

In addition, in the conventional tape feeder, a sprocket is used in the device that feeds the tape component 100, and the teeth on the outer periphery of the sprocket engage with the feed hole 110 of the tape component 100, and the tape component 100 is fed by rotating the sprocket. However, in many conventional tape feeders, the tape component is not fed in an upright state, but in a state in which the carrier tape of the tape component extends in the left-right direction, that is, the carrier tape and the upper surface of the tape feeder 82 are generally parallel to each other. In such a tape feeder, the sprocket is arranged to be rotatable around an axis extending in the left-right direction. In other words, the sprocket is arranged in a position extending in the up-down direction. On the other hand, in the tape feeder 82 of the present invention, the tape component 100 is fed in an upright state. Therefore, when a sprocket is used in the tape feeder 82, the sprocket is arranged to be rotatable around an axis extending in the up-down direction. In other words, the sprocket is arranged in a position extending in the left-right direction. If the sprocket is arranged in such a position, the width dimension of the tape feeder 82 increases, and the tape feeder 82 cannot be made compact. In addition, in order to engage the teeth of the sprocket with the feed hole 110 of the tape component 100 in an upright state, the teeth of the sprocket need to be not simply shaped, but have a shape that can prevent the teeth from falling out of the feed hole 110, so that the teeth of the sprocket can be reliably engaged with the feed hole 110. In view of this, in the tape feeder 82, in the first delivery device 85, the claw member 122 that engages with the feed hole 110 of the tape component 100 moves linearly in the feed direction of the tape component 100, that is, in the Y direction, and the tape component 100 is delivered by the claw member 122. This makes it possible to reduce the width dimension of the tape feeder 82 and make the tape feeder 82 compact.

In addition, when the radial part 102 is supplied, the claw member 122 or the like must be inserted into the feed hole of the taped part 100 and the lead 108 must be accurately positioned at the supply position. In addition, the claw member 122 must be inserted into the feed hole 110, and the taped part 100 must be cut in a state in which it does not move, that is, in a positioned state. In such a case, it is inevitable that the mechanism for feeding the taped part 100 and the mechanism for cutting the lead must be arranged so as to overlap in the width direction of the tape feeder 82. On the other hand, in order to prevent the width of the tape feeder 82 from becoming thicker, the mechanism of the second feed device 88 and the conveying rollers such as the first external roller 174 must be arranged at positions different from the supply position of the radial part 102 and the cutting position of the lead 108, and at positions that do not overlap with the supply position and the cutting position in the width direction of the tape feeder 82. In consideration of this, in the tape feeder 82, the second output device 88 is disposed in a position independent of the first output device 85, that is, in an independent position downstream of the first output device 85.

In addition, the feed hole 110 of the tape-formed component 100 may be used to feed the discharge tape, but as described above, since the second feed device 88 is independently arranged downstream of the first feed device 85, it is difficult to compensate for the change over time of the tape-formed component 100 and the environment, for example, the stretching of the carrier tape 104 due to humidity, and the uniformity of the component manufacturing accuracy and synchronous operation of the first feed device 85 and the second feed device 88. Furthermore, since the carrier tape 104 is stretched, cut, and bent, it is difficult to feed the tape-formed component 100 using the feed hole 110 at two locations, the first feed device 85 and the second feed device 88. In view of this, in the first feed device 85, the tape-formed component 100 is fed and positioned with the claw member 122 inserted into the feed hole 110, thereby ensuring reproducibility and supply positioning accuracy. On the other hand, because leads remain on the discharged tape and the remaining lead pitch is not accurate, the shape of the first external roller 174 of the second delivery device 88 is taken into consideration, as described above. This makes it possible to compensate for changes over time in the tape component 100 and the environment, such as stretching of the carrier tape 104 due to humidity, as well as the component manufacturing accuracy and uniformity of the synchronous operation of the first delivery device 85 and the second delivery device 88.

Furthermore, the first and second feed devices 85 and 88 are operated by a single drive source so that the relationship between the feed positions of the first and second feed devices 85 and 88 is not disrupted. This also makes it possible to reduce the cost of the tape feeder 82.

In the tape feeder 82, the first delivery device 85 delivers the taped component 100 by engaging the claw member 122 with the feed hole 110 of the taped component 100, and in the second delivery device 88, the discharged tape is wound around the first external roller 174 and the second external roller 176, and the discharged tape is delivered by the rotation of the first external roller 174 and the second external roller 176. This makes it possible to properly deliver the taped component 100 and the discharged tape even if there is a slight discrepancy between the timing of delivery of the taped component 100 and the timing of delivery of the discharged tape.

In detail, for example, in the second delivery device 88, as in the first delivery device 85, when the claw member engages with the feed hole 110 of the discharged tape to deliver the discharged tape, the first delivery device 85 and the second delivery device 88 take the lead in delivering the tape component 100 or the discharged tape. For this reason, it is necessary to ensure that the amount of tape component 100 delivered by the first delivery device 85 and the amount of discharged tape delivered by the second delivery device 88 are approximately consistent, and that the timing of delivery of tape component 100 by the first delivery device 85 and the timing of delivery of the discharged tape by the second delivery device 88 are approximately consistent. This is because if at least one of the delivery amount and delivery timing is misaligned, the claw member may not engage with the feed hole 110, the carrier tape 104 may slacken, or excessive tension may be generated in the carrier tape 104. On the other hand, by using a roller as the second delivery device 88 and using the rotational force of the roller to deliver the discharged tape, the first delivery device 85 takes the lead in delivering the tape component 100, while the second delivery device 88 delivers the discharged tape passively. This makes it possible for the second delivery device 88 to mitigate any deviations in the delivery amount, delivery timing, etc., and ensure proper delivery of the tape component 100 and discharged tape.

The taped component 100 is an example of a taped component. The radial component 102 is an example of a lead component. The carrier tape 104 is an example of a carrier tape. The lead 108 is an example of a lead. The feed hole 110 is an example of a feed hole. The claw member 122 is an example of an engagement portion.

The present invention is not limited to the above embodiment, and can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, the above embodiment employs taped component 100 with taped radial component 102, but it is possible to employ taped components with taped axial components.

In addition, in the above embodiment, the tape component 100 is sent out in an upright position, but it is possible to send out the tape component 100 not upright but extending in the left-right direction. In other words, it is possible to send out the tape component 100 in a state where the carrier tape 104 of the tape component 100 and the upper surface of the tape feeder 82 are generally parallel, in other words, in a state where the leads 108 taped to the carrier tape 104 extend in the left-right direction.

In the above embodiment, in the second delivery device 88, the first external roller 174 and the second external roller 176 rotate by the driving force of the cylinder 208 to deliver the discharged tape, but it is also possible to use rollers that do not have a drive source, i.e., rollers that do not rotate, and to arrange the delivery device for the discharged tape downstream of the discharged tape.

In the above embodiment, the taped component 100 is fed out by the engagement of the claw member 122 with the feed hole 110 or by winding it around a rotating roller, but it is possible to feed out the taped component 100 using various mechanisms. Specifically, for example, two rollers are brought into contact with each other on their roller surfaces, and the carrier tape 104 of the taped component 100 is sandwiched between the two rollers. The two rollers may then be rotated to feed out the taped component 100.

In addition, in the above embodiment, the direction in which the carrier tape 104 is fed by the second feeding device 88 is opposite to the direction in which the tape component 100 is fed by the first feeding device 85, but the direction in which the carrier tape 104 is fed by the second feeding device 88 can be set to various directions as long as it is different from the direction in which the tape component 100 is fed by the first feeding device 85.

In addition, in the above embodiment, a claw member 122 is used as an engagement portion that engages with the feed hole 110 of the tape component 100, but it is possible to use a member that has a protrusion, convex portion, hook portion, etc. that engages with the feed hole 110.
