Abstract

In this tape feeder, a pair of rollers (130), etc., are arranged so as to sandwich leads of axial components (76) held by a carrier tape (78) of a component tape (72) that is fed by a feeder device. The pair of rollers rotate in association with the feeding of the component tape by the feeder device. When this happens, as the pair of rollers rotate, the leads sandwiched by the pair of rollers are returned to the normal position, and the orientation of the axial components held by the carrier tape is corrected. Specifically, merely by arranging the pair of rollers, which have no drive source, so as to sandwich the leads of the axial components of the component tape makes it possible to correct the orientation of the axial components. It is thereby possible for the orientation of the axial components of the component tape to be corrected by a correction device having a simple structure.

<Configuration of electronic component mounting device>
FIG. 1 shows an electronic component mounting apparatus 10. The electronic component mounting apparatus 10 includes two electronic component mounting machines (hereinafter, may be abbreviated as “mounting machines”) 14. Each mounting machine 14 mainly includes a mounting machine body 20, a transport device 22, a moving device 24, a mounting head 26, and a supply device 28.

The mounting machine main body 20 includes a frame portion 32 and a beam portion 34 that is overlaid on the frame portion 32. The transport device 22 includes two

conveyor devices

40 and 42. Each of these two

conveyor devices

40 and 42 conveys the circuit board supported by each

conveyor device

40 and 42 in the X-axis direction.

The moving device 24 is an XY robot type moving device, and moves the slider 50 to an arbitrary position. Then, by attaching the mounting head 26 to the slider 50, the mounting head 26 is moved to an arbitrary position on the frame portion 32. The mounting head 26 has a suction nozzle 60 provided on the lower end surface. The suction nozzle 60 sucks and holds the electronic component with a negative pressure, and detaches the held electronic component with a positive pressure.

The mounting head 26 mounts electronic components on the circuit board. A suction nozzle 60 is provided on the lower end surface of the mounting head 26. The suction nozzle 60 communicates with a positive / negative pressure supply device (not shown) through negative pressure air and positive pressure air passages. As a result, the suction nozzle 60 sucks and holds the electronic component with a negative pressure, and releases the held electronic component with a positive pressure. The mounting head 26 has a nozzle lifting / lowering device (not shown) that lifts and lowers the suction nozzle 60 and changes the position of the electronic component to be held in the vertical direction.

The supply device 28 is a feeder-type supply device, and is disposed at the front end of the frame portion 32. The supply device 28 has a plurality of tape feeders 70. Each tape feeder 70 is an apparatus that removes an electronic component taped to a taped component and supplies the removed electronic component. The plurality of tape feeders 70 include an axial parts tape feeder 70a for supplying axial type lead parts (hereinafter sometimes referred to as “axial parts”), and radial type lead parts (hereinafter “radial parts”). There is a tape feeder 70b for a radial component that supplies a component).

The axial part tape feeder 70a is an apparatus that removes the axial part from the taped part (see FIG. 2) 72 and supplies the removed axial part in a bent state. As illustrated in FIG. 2, the taped component 72 includes a plurality of axial components 76 and two carrier tapes 78. The axial part 76 includes a generally cylindrical main body 80 and two lead wires 82. The two lead wires 82 are generally linear, and are fixed to both end faces of the main body 80 coaxially with the axis of the main body 80. Then, in a state where the axial part 76 is sandwiched between the two carrier tapes 78, the two lead wires 82, that is, the end opposite to the main body 80, are attached to the two carrier tapes 78. Taped. The plurality of axial parts 76 are taped to the two carrier tapes 78 at an equal pitch.

Further, as shown in FIG. 3, the tape feeder for axial parts 70a is composed of a taped part storage part 86 and a feeder body part 88. A connector 90 and two pins 92 are provided on the front end surface of the feeder main body 88. When the tape feeder 70 is attached to the frame portion 32, the connector 90 is formed on the frame portion 32. The pin 92 is fitted into a pin hole (not shown) formed in the frame portion 32. Further, the taped component 72 is stored in the taped component storage portion 86. Then, the taped component 72 stored in the taped component storage unit 86 is pulled out, and the taped component 72 extends to the upper end surface of the feeder main body 88.

In the feeder main body 88, a feeding device 96 and a forming / cutting device 98 are disposed. The feeding device 96 is a device that feeds the taped component 72 toward the front side of the tape feeder 70. As a result, the taped component 72 is sent out from the taped component storage portion 86 toward the supply position on the front side of the upper end surface of the taped component 72.

Further, the forming / cutting device 98 is a device for cutting the axial component 76 from the taped component 72 fed by the feeding device 96 and bending the lead wire 82 of the axial component 76. Specifically, the two lead wires 82 taped to the carrier tape 78 of the taped component 72 are supported from below by a pair of support claws (not shown). Then, the lead wire 82 supported by the support claw is cut between a portion taped on the carrier tape 78 and a portion supported by the support claw. Further, the cut lead wire 82 is bent between the distal end portion and the proximal end portion. The pair of lead wires 82 are bent at right angles in the same direction. As a result, the axial part 76 is generally formed in a “U” shape, and is supplied at the supply position in a state where the distal ends of the pair of bent lead wires 82 are held.

The radial part tape feeder 70b is a device that removes the radial part from the taped part (see FIG. 4) 100 and supplies the removed radial part. The taped component 100 is composed of a plurality of radial components 102 and a carrier tape 104 as shown in FIG. The radial component 102 includes a main body portion 106 and two lead wires 108. The two lead wires 108 are generally linear and extend in parallel from the lower end surface of the main body portion 106. The two lead wires 108 are taped to the carrier tape 104 at the tip, that is, the end opposite to the main body 106. The plurality of radial parts 102 are taped to the carrier tape 104 at an equal pitch.

Further, since the radial part tape feeder 70b has substantially the same configuration as the axial part tape feeder 70a except for the cutting device, the illustration of the radial part tape feeder 70b is omitted, and only the cutting device will be described. The cutting device holds the radial component 102 of the taped component 100 being fed by the feeding device with a pair of lead wires 108. Then, the held lead wire 108 is cut between the portion taped on the carrier tape 104 and the held portion. As a result, the radial component 102 held at the tip of the pair of lead wires 108 is supplied.

<Mounting work with a mounting machine>
In the mounting machine 14, the mounting operation can be performed by the mounting head 26 on the circuit board held by the transport device 22 with the above-described configuration. Specifically, the circuit board is transported to the working position and is fixedly held at that position by a command from a control device (not shown) of the mounting machine 14. Further, the tape feeder 70 sends out the taped

parts

72 and 100 and supplies the axial part 76 or the radial part 102 at the supply position in accordance with a command from the control device. Then, the mounting head 26 moves above the supply position, and the suction part 60 sucks and holds the axial part 76 or the radial part 102. Subsequently, the mounting head 26 moves above the circuit board and mounts the held axial component 76 or radial component 102 on the circuit board. At this time, the lead wire 82 of the axial component 76 or the lead wire 108 of the radial component 102 is inserted into a through hole formed in the circuit board.

<Correction of taped parts>
As described above, in the mounting machine 14, during the mounting operation, the lead wire 82 of the axial component 76 or the lead wire 108 of the radial component 102 is inserted into the through hole formed in the circuit board. However, the axial part 76 or the radial part 102 may be taped in a state where the taped

parts

72 and 100 are deviated from a normal posture. Specifically, for example, as shown in FIG. 2, the axial part 76 is shifted from the normal posture (dotted line in the figure) to the front and back in the feeding direction of the taped part 72 or in the vertical direction. In some cases, the tape 78 is taped. In addition, for example, as shown in FIG. 4, the radial component 102 is shifted from the normal posture (dotted line in the figure) to the carrier tape 104 in a state where the radial direction 102 is shifted in the front-back direction or the left-right direction of the taped component 100. It may be taped.

As described above, in the axial part 76 or the radial part 102 taped in a shifted state, the

lead wires

82 and 108 do not extend in an appropriate direction. For this reason, when such an axial component 76 or the radial component 102 is mounted on the circuit board, the

lead wires

82 and 108 may not be properly inserted into the through holes formed in the circuit board.

Further, when the axial part 76 or the radial part 102 is supplied, the axial parts 76 taped on the

carrier tapes

78 and 104 or the

lead wires

82 and 108 of the radial part 102 are supplied as described above. Hold and cut. However, the axial parts 76 or the radial parts 102 taped to the

carrier tapes

78 and 104 in a shifted state cannot hold the

lead wires

82 and 108 properly, and the

lead wires

82 and 108 are cut. There is a possibility that it cannot be done. That is, there is a possibility that the axial component 76 or the radial component 102 taped on the

carrier tapes

78 and 104 in a shifted state cannot be supplied by the tape feeder 70.

In view of the above, the tape feeder 70 is provided with a correction device for correcting the posture of the axial part 76 or the radial part 102 taped to the

carrier tapes

78 and 104. Specifically, as shown in FIGS. 5 and 6, the correction device 120 is disposed in the axial component tape feeder 70 a that supplies the axial component 76 from the taped component 72.

The thickness of each roller 130, that is, the length in the axial direction of each roller 130 is about half of the length of the exposed lead wire 82, and the pair of

rollers

130 a and 130 b are used as leads. It arrange | positions so that only the line | wire 82 may be pinched | interposed.

Further, the second roller device 124 is arranged on the downstream side of the first roller device 122 in the feeding direction of the taped component 72, and is constituted by four rollers 132 having the same size. Two of the four rollers 132 are paired with a pair of brackets (not shown) so that one of the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 is sandwiched from above and below. (Omitted) is pivotally supported. Of the four rollers 132, two rollers 132a and another two rollers 132b are paired, and the other of the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 is vertically moved. It is pivotally supported by a bracket (not shown) so as to be sandwiched between them.

Further, the surface of each roller 132 is formed of an elastically deformable material, and is a smooth surface without unevenness. The distance between the pair of

rollers

132a and 132b, that is, the distance between the roller 132a and the roller 132a and the distance between the roller 132b and the roller 132b are the distance between the pair of

rollers

130a and 130b of the first roller device 122. The width of the roller 132 is such that each roller 132 comes into contact with the lead wire 82 and is greatly elastically deformed. The thickness of each roller 132 is larger than the thickness of each roller 130 of the first roller device 122, and a pair of

rollers

132 a and 132 b are disposed so as to sandwich the lead wire 82 and the carrier tape 78. Has been.

Further, the third roller device 126 is arranged on the downstream side of the second roller device 124 in the feeding direction of the taped component 72, and is constituted by four rollers 134 having the same size. Of the four rollers 134, two rollers 134a are paired with a bracket (not shown) so as to sandwich one of the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 from above and below. (Omitted) is pivotally supported. Of the four rollers 134, two rollers 134a and another two rollers 134b form a pair, and the other of the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 is vertically moved. It is pivotally supported by a bracket (not shown) so as to be sandwiched between them.

The surface of each roller 134 is formed of a material that cannot be elastically deformed, and a concave portion or a convex portion is formed on the surface of each roller 134 so that the pair of

rollers

134a and 134b mesh with each other. Has been. Specifically, as shown in FIG. 7, a plurality of convex portions 136 are formed at an equal pitch on one surface of the pair of

rollers

134a and 134b. On the other hand, a plurality of concave portions 138 are formed on the other surface of the pair of

rollers

134a and 134b at the same pitch as the pitch of the convex portions 136 formed. The shape of the concave portion 138 is slightly larger than the shape of the convex portion 136, and the convex portion 136 enters the concave portion 138 as the roller 134 rotates. At this time, the lead wire 82 sandwiched between the pair of

rollers

134 a and 134 b enters between the convex portion 136 and the concave portion 138. However, the distance between the pair of

rollers

134a and 134b, that is, the distance between the roller 134a and the roller 134a, and the distance between the roller 134b and the roller 134b are the lead wires 82 that enter between the convex portion 136 and the concave portion 138. The interval is about 2 to 3 times as large as the thickness.

Further, the formation pitch of the convex portions 136 and the formation pitch of the concave portions 138 are the same as the arrangement pitch of the axial parts 76 taped on the carrier tape 78. For this reason, as the taped component 72 is fed, each roller 134 rotates, and the lead wire 82 of the axial component 76 taped to the carrier tape 78 sequentially enters between the convex portion 136 and the concave portion 138. The thickness of each roller 134 is about half of the length of the exposed lead wire 82, and a pair of

rollers

134 a and 134 b are disposed so as to sandwich only the lead wire 82. .

Further, as shown in FIGS. 5 and 6, the fourth roller device 128 is disposed on the downstream side of the third roller device 126 in the feeding direction of the taped component 72, and is provided with four rollers of the same size. 140. Of the four rollers 140, two rollers 140a are paired, and a bracket (not shown) is interposed between the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 from above and below. (Omitted) is pivotally supported. Of the four rollers 140, two rollers 140a and another two rollers 140b form a pair, and the other of the pair of lead wires 82 of the axial part 76 taped to the carrier tape 78 is vertically moved. It is pivotally supported by a bracket (not shown) so as to be sandwiched between them.

The surface of each roller 140 is formed of a material that cannot be elastically deformed, and a convex portion or a concave portion is formed on the surface of each roller 140 so that the pair of

rollers

140a and 140b mesh with each other. Has been. In addition, since the convex part and recessed part which are formed in each roller 140 are the same shape as the convex part 136 and concave part 138 which are formed in each roller 134, description and illustration are abbreviate | omitted. Also in the fourth roller device 128, the lead wire 82 sandwiched between the pair of

rollers

140a and 140b enters between the convex portion and the concave portion as the roller 140 rotates. However, the distance between the pair of

rollers

140a and 140b, that is, the distance between the

rollers

140a and 140a and the distance between the

rollers

140b and 140b are the distance between the pair of

rollers

134a and 134b of the third roller device 126. Although narrower, the lead wire 82 entering between the convex portion and the concave portion is set so as not to be crushed. The thickness of each roller 140 is larger than the thickness of each roller 134 of the third roller device 126, and a pair of

rollers

140 a and 140 b are disposed so as to sandwich the lead wire 82 and the carrier tape 78. Has been.

With the above-described configuration, the correction device 120 corrects the posture of the axial part 76 taped on the carrier tape 78 as the taped part 72 is fed out. Specifically, the taped component 72 is sent out by the delivery device 96, so that the rollers 130 and 132 of the

roller devices

122, 124, 126, and 128 sandwiching the lead wire 82 of the axial component 76 taped to the carrier tape 78. , 134, 140 rotate. At this time, the axial component 76 positioned upstream of the first roller device 122 is sent to the first roller device 122, and the lead wire 82 of the axial component 76 is sandwiched between the pair of

rollers

130a and 130b. . Thereby, the attitude | position of the axial component 76 is corrected in the up-down direction.

However, as described above, the distance between the pair of

rollers

130a and 130b is such that each roller 130 slightly contacts the lead wire 82, and the thickness of each roller 130 is relatively thin. . For this reason, the posture of the axial part 76 sandwiched between the pair of

rollers

130a and 130b is corrected only to some extent. However, since the distance between the pair of

rollers

130a and 130b is not so narrow and the thickness of each roller 130 is thin to some extent, even if the attitude of the axial part 76 is greatly deviated, the lead wire 82 is The pair of

rollers

130a and 130b can be appropriately sandwiched.

Further, when the taped component 72 is sent out by the feeding device 96, the axial component 76 whose posture is corrected by the first roller device 122 is sent to the second roller device 124, and the lead wire 82 of the axial component 76 is connected. It is sandwiched between a pair of

rollers

132a and 132b. Thereby, the attitude | position of the axial component 76 is corrected in the up-down direction. At this time, as described above, the distance between the pair of

rollers

132a and 132b is narrower than the pair of

rollers

130a and 130b of the first roller device 122, and the thickness of each roller 132 is set to the first roller device 122. The roller 130 is thicker. For this reason, the axial component 76 whose posture is corrected by the first roller device 122 is further corrected by the second roller device 124.

Further, the taped component 72 is further fed by the feeding device 96, so that the axial component 76 whose posture is corrected by the second roller device 124 is fed to the third roller device 126, and the lead wire of the axial component 76 is sent. 82 is sandwiched between a pair of

rollers

134a and 134b. At this time, the lead wire 82 enters between the convex portion 136 and the concave portion 138 of the pair of

rollers

134a and 134b. Thereby, the posture of the axial part 76 is corrected not only in the vertical direction but also in the front-rear direction in the feeding direction of the taped part 72.

However, as described above, the distance between the pair of

rollers

134a and 134b is about 2 to 3 times the thickness of the lead wire 82 that has entered between the convex portion 136 and the concave portion 138. The thickness is relatively thin. For this reason, the posture in the front-rear direction of the axial part 76 sandwiched between the pair of

rollers

134a and 134b is corrected only to some extent. However, since the distance between the pair of

rollers

134a and 134b is not so narrow and the thickness of each roller 134 is somewhat thin, even if the attitude of the axial component 76 is greatly displaced, the lead wire 82 is The pair of

rollers

134a and 134b can be appropriately sandwiched.

Then, the taped component 72 is further fed by the feeding device 96, so that the axial component 76 whose posture is corrected by the third roller device 126 is fed to the fourth roller device 128, and the lead wire of the axial component 76 is sent. 82 is sandwiched between a pair of

rollers

140a and 140b. At this time, the lead wire 82 enters between the convex portion and the concave portion of the pair of

rollers

140a and 140b. Thereby, the attitude | position of the axial component 76 is corrected in the up-down direction and the front-back direction. At this time, as described above, the distance between the pair of

rollers

140a and 140b is narrower than the pair of

rollers

134a and 134b of the third roller device 126, and the thickness of each roller 140 is the third roller device. It is thicker than 126 rollers 134. For this reason, the axial component 76 whose posture is corrected by the third roller device 126 is further corrected by the fourth roller device 128.

As described above, in the correction device 120, the posture of the axial component 76 of the taped component 72 is corrected by the plurality of

roller devices

122, 124, 126, and 128, thereby ensuring proper mounting work and axial. It is possible to reduce the number of axial components 76 that cannot be supplied from the component tape feeder 70a. Further, in the correction device 120, the rollers 130, 132, 134, and 140 rotate using the feeding of the taped component 72 without providing its own drive source. As a result, the structure of the correction device 120 can be simplified.

In the straightening device 120, the interval between the pair of rollers on the downstream side is narrower than the interval between the pair of rollers on the upstream side. Further, the thickness of the downstream roller is larger than the thickness of the upstream roller. Thereby, even when the attitude of the axial component 76 is largely deviated, the lead wire 82 can be appropriately sandwiched by the pair of upstream rollers. The posture of the axial component 76 can be further corrected by the pair of rollers on the downstream side than the pair of rollers on the upstream side.

Further, the correction device 120 employs two types of roller devices:

roller devices

122 and 124 having smooth roller surfaces, and

roller devices

126 and 128 having roller rollers with uneven surfaces. The

roller devices

122 and 124 can appropriately correct the vertical displacement of the axial component 76, and the

roller devices

126 and 128 can appropriately correct the longitudinal displacement of the axial component 76. As a result, the posture of the axial component 76 can be corrected appropriately.

Further, in the

roller devices

126 and 128 having rollers with uneven rollers, the lead wire 82 is sandwiched between the recesses and the protrusions, so that when the attitude of the axial component 76 is greatly shifted, There is a possibility that the lead wire 82 does not enter between the concave portion and the convex portion. Therefore, in the correction device 120, the

roller devices

126 and 128 having rollers with uneven surfaces are arranged on the downstream side of the

roller devices

122 and 124 having rollers with smooth roller surfaces. As a result, the axial component 76 that has been corrected to some extent can be fed into the

roller devices

126 and 128, and the lead wire 82 can be appropriately sandwiched between the concave portion and the convex portion.

Further, as shown in FIGS. 8 and 9, the straightening device 150 is disposed in the radial part tape feeder 70b for supplying the radial part 102 from the taped part 100. Since the straightening device 150 has a structure similar to the straightening device 120 disposed in the axial part tape feeder 70a, the structure common to the straightening device 120 will be briefly described. FIG. 8 is a diagram showing the taped component 100 from the side, and FIG. 9 is a diagram showing the taped component 100 from the top.

The straightening device 150 is disposed on the upstream side of the cutting device of the radial part tape feeder 70b, and includes four sets of

roller devices

152, 154, 156, and 158. The four sets of

roller devices

152, 154, 156, and 158 are arranged along the taped component 100, and the roller device (hereinafter referred to as “first roller device”) is directed toward the feeding direction of the taped component 100. 152, a roller device (hereinafter sometimes referred to as “second roller device”) 154, a roller device (hereinafter sometimes referred to as “third roller device”) 156, a roller device (Hereinafter, it may be described as “fourth roller device”) 158 is arranged in this order.

The first roller device 152 includes a pair of rollers 160 having the same size. The pair of rollers 160 is rotatably supported by a bracket (not shown) so that the pair of lead wires 108 of the radial part 102 taped on the carrier tape 104 is sandwiched from the left and right directions of the taped part 100. Has been. The distance between the pair of rollers 160, the thickness of the roller 160, the shape of the roller 160, and the like are the same as those of the roller 130 of the first roller device 122 of the correction device 120.

The second roller device 154 is disposed on the downstream side of the first roller device 152 in the feeding direction of the taped component 100, and is configured by a pair of rollers 162 having the same size. The pair of rollers 162 are pivotally supported by a bracket (not shown) so as to sandwich a pair of lead wires 108 of the radial part 102 taped on the carrier tape 104 from the left and right directions of the taped part 100. Has been. The distance between the pair of rollers 162, the thickness of the roller 162, the shape of the roller 162, and the like are the same as those of the roller 132 of the second roller device 124 of the correction device 120.

Further, the third roller device 156 is disposed on the downstream side of the second roller device 154 in the feeding direction of the taped component 100, and is configured by a pair of rollers 164 having the same size. The pair of rollers 164 is pivotally supported by a bracket (not shown) so as to sandwich a pair of lead wires 108 of the radial part 102 taped on the carrier tape 104 from the left and right directions of the taped part 100. Has been.

A convex portion 166 having the same shape as the convex portion 136 of the roller 134 of the third roller device 126 of the correction device 120 is formed on one of the pair of rollers 164, and the other of the pair of rollers 164 is formed on the other side. A recess 168 having the same shape as the recess 138 of the roller 134 is formed. However, unlike the convex portion 136 and the concave portion 138 of the roller 134, in the convex portion 166 or the concave portion 168 of the roller 164, the interval between the two adjacent convex portions 166 or the concave portion 168 is a pair of leads of the radial component 102. It is the same as the interval between the lines 108. Accordingly, as the roller 164 rotates, the pair of lead wires 108 sandwiched between the pair of rollers 164 enters between the convex portion 166 and the concave portion 168. Further, when these two adjacent convex portions 166 or concave portions 168 are set as one set, the formation pitch for each set is the same as the arrangement pitch of the radial components 102 taped on the carrier tape 104. For this reason, as the taped component 100 is sent out, each roller 164 rotates, and the lead wires 108 of the radial component 102 taped on the carrier tape 104 sequentially enter between the convex portion 166 and the concave portion 168. The distance between the pair of rollers 164 and the thickness of the roller 164 are the same as those of the roller 134 of the third roller device 126 of the correction device 120.

Further, the fourth roller device 158 is disposed on the downstream side of the third roller device 156 in the feeding direction of the taped component 100, and is configured by a pair of rollers 170 having the same size. The pair of rollers 170 is rotatably supported by a bracket (not shown) so that the pair of lead wires 108 of the radial part 102 taped on the carrier tape 104 is sandwiched from the left and right directions of the taped part 100.

Further, one of the pair of rollers 170 is formed with a convex portion 172 having the same shape as the convex portion 166 of the roller 164 of the third roller device 156, and the other of the pair of rollers 170 has the roller 164. A recess 174 having the same shape as the recess 168 is formed. The formation pitch of the projections 172 and the recesses 174 is the same as the formation pitch of the projections 166 and the recesses 168. Accordingly, as the roller 170 rotates, the pair of lead wires 108 sandwiched between the pair of rollers 170 enters between the convex portion 172 and the concave portion 174. Then, as the taped component 100 is sent out, each roller 170 rotates, and the lead wire 108 of the radial component 102 taped to the carrier tape 104 sequentially enters between the convex portion 172 and the concave portion 174. The distance between the pair of rollers 170 and the thickness of the roller 170 are the same as those of the roller 140 of the fourth roller device 128 of the correction device 120.

With the above-described configuration, the correction device 150 corrects the posture of the radial component 102 taped on the carrier tape 104 as the taped component 100 is fed out.
