The mark camera 26 is attached to the slider 74 while facing downward, and is moved together with the work head 60 in the X direction, the Y direction, and the Z direction. As a result, the mark camera 26 images an arbitrary position on the frame 40. Further, as shown in FIG. 1, the parts camera 28 is arranged in a state of facing upward between the base material carrying/holding device 22 and the component supply device 32 on the frame 40. As a result, the parts camera 28 images the parts held by the suction nozzles 66 of the

work heads

60 and 62.

The bulk component supply device 30 is arranged at one end of the frame 40 in the front-rear direction. The discrete component supply device 30 is a device that aligns a plurality of components in a scattered state and supplies the components in the aligned state. In other words, it is a device that aligns a plurality of components in arbitrary postures in a predetermined posture and supplies the components in a predetermined posture.

The component supply device 32 is arranged at the other end of the frame 40 in the front-rear direction. The component supply device 32 has a tray-type component supply device 96 and a feeder-type component supply device 98. The tray-type component supply device 96 is a device that supplies the components placed on the tray. The feeder-type component supply device 98 is a device that supplies components by the tape feeder 100. The tape feeder 100 will be described in detail below. The components supplied by the bulk component supply device 30 and the component supply device 32 include electronic circuit components, solar cell components, power module components, and the like. Further, electronic circuit parts include parts with leads and parts without leads.

As shown in FIG. 3, the tape feeder 100 includes a feeder main body 102, and in the feeder main body 102, the tape feeder 100 is removably mounted on a mounting base (see FIG. 1) 104 provided at an end of the frame 40. The tape feeder 100 sends the tape-formed component (see FIG. 4) 106 toward the supply position, and supplies the electronic component from the tape-formed component 106 at the supply position.

As shown in FIG. 4, the tape component 106 includes a carrier tape 108, an electronic component 110, and a top cover tape 112. The carrier tape 108 has a large number of accommodating recesses 114 and feed holes 116 formed at equal pitches, and the accommodating recesses 114 accommodate the electronic components 110. The housing recess 114 in which the electronic component 110 is housed is covered with the top cover tape 112.

Further, as shown in FIG. 3, the tape feeder 100 has a tape reel 120, a feeding device 122, a peeling device 124, a discharge path 126, and a cutting device 128. The tape reel 120 is rotatably held at the end portion of the feeder main body 102, and the tape reel component 106 is wound around the tape reel 120. In the following description, the side on which the tape reel 120 is arranged is referred to as the rear side, and the side opposite to the rear side is referred to as the front side. Then, the tape-forming component 106 is pulled out from the tape reel 120 toward the front and extends to the upper end surface of the feeder main body 102.

Further, the feeding device 122 is disposed inside the feeder main body 102 at the front end of the feeder main body 102. The feeding device 122 has a sprocket (not shown), and the sprocket is engaged with the feed hole 116 of the tape-making component 106 extending to the upper end surface of the feeder main body 102. Then, the sprocket is rotated by the drive of an electromagnetic motor (not shown), so that the tape-making component 106 is delivered to the supply position 130 at a predetermined pitch on the upper end surface of the feeder body 102. The pitch at which the tape-making components 106 are fed by the feeding device 122 is the pitch at which the feed holes 116 are formed. That is, the sprocket engaged with the feed hole 116 is rotated by an angle corresponding to the formation pitch of the feed hole 116, so that the tape-making component 106 moves toward the supply position 130 at the same pitch as the formation pitch of the feed hole 116. Sent out. Further, the formation pitch of the accommodation recess 114 in which the electronic component 110 is accommodated is the same as the formation pitch of the feed hole 116. Therefore, every time the tape-forming component 106 is delivered by the delivery device 122, the housing recess 114 in which the electronic component 110 is housed is delivered to the supply position 130.

Further, in the tape forming component 106 extending to the upper end surface of the feeder main body 102, the top cover tape 112 is peeled from the carrier tape 108 on the rear side of the supply position 130, and the peeled top cover tape 112. Are pulled by the peeling device 124. As a result, the accommodation recess 114 of the tape-making component 106 is sequentially opened on the rear side of the supply position 130 on the upper end surface of the feeder body 102. Then, when the opened housing recess 114 is delivered to the supply position 130, the electronic component 110 is held by the suction nozzle 66 from the housing recess 114.

A discharge path 126 is arranged in front of the supply position 130. In the discharge path 126, a carrier tape (hereinafter referred to as “remaining tape”) 132 (see FIG. 7) in a state where the top cover tape 112 is peeled off and the electronic component 110 is taken out from the housing recess 114 (see FIG. 7) is provided in the tape feeder 100. It is for discharging to the outside. As shown in FIGS. 3 and 5, the discharge path 126 is composed of a first duct 136 and a second duct 138. The first duct 136 extends forward from the supply position 130, then curves downward, and further curves rearward. Then, the residual tape 132 is sent from the supply position 130 toward the inside of the first duct 136. That is, the transport direction of the residual tape 132 delivered from the supply position 130 is converted from the front to the rear in the first duct 136 that is curved in a semicircular arc.

Specifically, the conveyance direction of the residual tape 132 immediately after being fed from the supply position 130 is forward, but in the first duct 136, first, the residual tape 132 is converted to a diagonally downward direction with the conveyance of the residual tape 132. And then converted downwards. Then, as the residual tape 132 is further conveyed, it is converted to a diagonally downward direction. At this time, the remaining tape 132 is turned upside down. That is, at the supply position 130, the residual tape 132 is in a posture in which the accommodating concave portion 114 is directed upward. 132 is in a posture in which the accommodating recess 114 is directed downward.

Also, as shown in FIG. 3, the second duct 138 is continuous from the first duct 136 and extends linearly while inclining toward the rear of the feeder main body 102. The rear end of the second duct 138 opens at the lower end surface of the feeder main body 102. As a result, the residual tape 132 is conveyed from the first duct 136 to the second duct 138, and the residual tape 132 is conveyed to the outside of the tape feeder 100 via the second duct 138.

However, in order to prevent clogging of the residual tape 132 in the second duct 138, a cutting device 128 for cutting the residual tape 132 is provided between the first duct 136 and the second duct 138. .. As shown in FIGS. 5 to 7, the cutting device 128 includes a housing 150, a tape cutting mechanism 152, a tape pressing mechanism 154, an air cylinder 156, and a conversion mechanism 158.

The housing 150 has a generally box shape, and the front surface and the rear surface are open. The first duct 136 is connected to the front surface of the housing 150 that opens, and the second duct 138 is connected to the rear surface of the housing 150 that opens. As a result, the inside of the first duct 136 and the inside of the housing 150 communicate with each other, and the inside of the second duct 138 and the inside of the housing 150 communicate with each other. That is, the first duct 136 and the second duct 138 communicate with each other via the housing 150 of the cutting device 128. Therefore, the inside of the housing 150 forms a part of the discharge path 126, and the residual tape 132 passes through the inside of the housing 150 when being conveyed from the first duct 136 to the second duct 138.

Further, the tape cutting mechanism 152 has a movable block 160, a movable blade 162, and a fixed blade 164. The movable block 160 is sandwiched by a pair of side surfaces 166 of the housing 150 so as to be slidable in the vertical direction. A movable blade 162 is fixedly erected on the upper surface of the movable block 160. A fixed blade 164 is removably fastened to the upper surface 168 of the housing 150 at a position facing the movable blade 162 with a bolt. Therefore, the fixed blade 164 can be easily replaced. Then, as the movable block 160 slides upward, the movable blade 162 rises together with the movable block 160 and comes into sliding contact with the fixed blade 164. With such a structure, the tape cutting mechanism 152 cuts the residual tape 132 passing through the inside of the housing 150 in the discharge path 126 by the movable blade 162 and the fixed blade 164.

Also, the tape pressing mechanism 154 has a pressing rod 170 and a fixed block 172. The pressing rod 170 is erected on the upper surface of the movable block 160 on the rear side of the movable blade 162 so as to extend in the same direction as the direction in which the movable blade 162 extends. However, the pressing rod 170 is held by the movable block 160 so as to be slidable in the vertical direction, and is biased upward by a coil spring (not shown).

The upward bias of the pressing rod 170 by the coil spring is restricted by a stopper (not shown). At this time, the upper end of the pressing rod 170 is located above the upper end of the movable blade 162, as shown in FIG. 7, in a state where the upward bias of the pressing rod 170 is restricted by the stopper. However, when the pressing rod 170 is pressed downward against the elastic force of the coil spring, the lower end of the pressing rod 170 enters the inside of the movable block 160, and the upper end of the pressing rod 170 moves as shown in FIG. It is located below the upper end of the blade 162.

Further, the fixed block 172 is detachably fastened to the upper surface 168 of the housing 150 with a bolt so as to face the upper end of the pressing rod 170. Therefore, the fixed block 172 can be easily replaced. Then, as the movable block 160 slides upward, the pressing rod 170 rises together with the movable block 160, and the tip of the pressing rod 170 is the lower surface of the fixed block 172 (hereinafter referred to as the “pressing surface”) 174. Abut. At this time, the pressing rod 170 comes into contact with the pressing surface 174 in a state of being orthogonal thereto. With such a structure, the tape pressing mechanism 154 pushes the residual tape 132 passing through the inside of the housing 150 in the discharge path 126 upward from below by the pressing rod 170 and presses it against the pressing surface 174.

The lower surface of the fixed block 172, that is, the pressing surface 174, is located at substantially the same height as the lower end of the fixed blade 164. In addition, the pressing surface 174 is located at substantially the same height as the lower surface of the top plate of the first duct 136 and the second duct 138 that define the discharge path 126, or slightly above the lower surface of the top plate. That is, the pressing surface 174 of the fixed block 172, the lower end of the fixed blade 164, and the lower surface of the top plate of the first duct 136 and the second duct 138 are flush with each other, or the pressing surface 174 of the fixed block 172 is fixed. The lower end of the blade 164 is recessed slightly upward from the lower surfaces of the top plates of the first duct 136 and the second duct 138. This prevents the residual tape 132 from being caught by the fixed blade 164 and the fixed block 172 when the residual tape 132 is conveyed from the first duct 136 to the second duct 138 via the inside of the housing 150. be able to.

Further, as shown in FIG. 5, the air cylinder 156 is disposed behind the housing 150 and below the second duct 138 so as to extend in the front-rear direction. The piston rod 176 of the air cylinder 156 extends toward the lower end of the housing 150, and the tip of the piston rod 176 is connected to the movable block 160 via the conversion mechanism 158. The conversion mechanism 158 converts the movement of the piston rod 176 in the front-back direction into the movement of the movable block 160 in the vertical direction. As a result, the movable block 160 moves in the vertical direction by operating the air cylinder 156. With such a structure, in the cutting device 128, the residual tape 132 pressed by the tape pressing mechanism 154 is cut by the tape cutting mechanism 152.

Specifically, after the electronic component 110 is taken out from the accommodation recess 114 of the carrier tape 108 at the supply position 130, the carrier tape 108 from which the electronic component 110 is taken out, that is, the residual tape 132, is placed inside the first duct 136. It is conveyed toward you. Then, as the residual tape 132 is conveyed, the conveying direction of the residual tape 132 is changed from the front side to the rear side in the first duct 136. Then, the residual tape 132 is conveyed from the first duct 136 into the housing 150. At this time, the residual tape 132 was conveyed in a curved state inside the first duct 136, but inside the housing 150, it is conveyed in a straight state without being curved. Then, the residual tape 132 is conveyed toward the inside of the second duct 138 via the inside of the housing 150. The remaining tape 132 is conveyed in the discharge path 126 every time the tape-forming component 106 is sent out by the sending device 122 at a predetermined pitch.

Further, when the residual tape 132 is conveyed, the air cylinder 156 of the cutting device 128 is contracted and the movable block 160 is lowered, as shown in FIG. 7. For this reason, the movable blade 162 and the pressing rod 170 also descend together with the movable block 160 and exit from the discharge path 126, so that the conveyance of the residual tape 132 in the discharge path 126 is secured. Then, the air cylinder 156 extends at the timing when the delivery of the tape-formed component 106 by the delivery device 122 is completed, that is, the timing when the transport of the residual tape 132 on the ejection path 126 is stopped.

At this time, the movable block 160 rises, and the movable blade 162 and the pressing rod 170 also rise together with the movable block 160. As a result, the movable blade 162 and the pressing rod 170 enter the inside of the discharge path 126, as shown in FIG. 8, and the pressing rod 170 remains bent by gravity passing through the inside of the housing 150 in the discharge path 126. Push the tape 132 upwards. Then, the pressing rod 170 presses the residual tape 132 against the pressing surface 174. At this time, the residual tape 132 is pressed against the pressing surface 174 by the elastic force of the coil spring.

Subsequently, the air cylinder 156 further extends, so that the movable blade 162 further rises together with the movable block 160. However, since the pressing rod 170 is in contact with the pressing surface 174 via the residual tape 132, the lower end of the pressing rod 170 enters the inside of the movable block 160 as the movable block 160 moves up. At this time, as shown in FIG. 9, the movable blade 162 rises above the upper end of the pressing rod 170 along the extending direction of the pressing rod 170 and comes into sliding contact with the fixed blade 164 on the front side of the pressing rod 170. .. As a result, the residual tape 132 pressed against the pressing surface 174 by the pressing rod 170 on the rear side of the movable blade 162 is cut by the movable blade 162 and the fixed blade 164. When the residual tape 132 is cut by the movable blade 162 and the fixed blade 164, the air cylinder 156 contracts and the movable blade 162 and the pressing rod 170 descend. As a result, the cut residual tape (hereinafter referred to as “remaining tape piece”) slides down inside the discharge path 126 and is discharged to the outside of the tape feeder 100.

As described above, in the tape feeder 100, the residual tape 132 pressed by the tape pressing mechanism 154 is cut by the tape cutting mechanism 152, so that the residual tape 132 can be properly used as compared with the conventional tape feeder. Can be cut into Specifically, in the conventional tape feeder, the tape pressing mechanism 154 is not provided, but only the tape cutting mechanism 152 is provided. Therefore, as the movable blade 162 moves up, the residual tape 132 is pushed upward by the movable blade 162 and cut by the fixed blade 164 and the movable blade 162. That is, since the residual tape 132 is cut while being pushed up by the movable blade 162, the residual tape 132 in an unstable posture is cut by the movable blade 162 and the fixed blade 164. Therefore, at the time of cutting, the residual tape 132 may be sandwiched between the movable blade 162 and the fixed blade 164, and the residual tape 132 may not be appropriately cut. Further, when the residual tape 132, that is, the carrier tape 108 is made of plastic, if the residual tape 132 is cut in an unstable posture, the residual tape 132 may not be properly cut and may be crushed. .. Furthermore, the residual tape 132 may not be cut and may be crushed by being sandwiched between the movable blade 162 and the fixed blade 164. As described above, when the residual tape 132 is not properly cut, the residual tape 132 sandwiched between the movable blade 162 and the fixed blade 164, the crushed residual tape 132, the crushed residual tape 132, and the like are discharged to the discharge path 126. May get stuck in.

On the other hand, in the tape feeder 100, the residual tape 132 pressed by the tape pressing mechanism 154 is cut by the tape cutting mechanism 152. That is, the residual tape 132 is pressed by the tape pressing mechanism 154 and then cut by the tape cutting mechanism 152. Therefore, the residual tape 132 in the posture pressed by the tape pressing mechanism 154, that is, the residual tape 132 held in a stable posture is cut by the tape cutting mechanism 152. As a result, in the tape feeder 100, the residual tape 132 can be appropriately cut, and the clogging of the residual tape 132 in the discharge path 126 can be prevented.

Also, the movable blade 162 and the pressing rod 170 extend in the same direction. The pressing rod 170 extends in a direction perpendicular to the pressing surface 174. Therefore, the pressing rod 170 presses the residual tape 132 against the pressing surface 174 in a state where it is orthogonal to the residual tape 132 and is not twisted, and the movable blade 162 is orthogonal to the residual tape 132. The tape 132 is cut. Thereby, the residual tape 132 can be cut appropriately.

Furthermore, the pressing surface 174 is located at substantially the same height as the lower end of the fixed blade 164. Therefore, the bottom surface of the residual tape 132 pressed against the pressing surface 174 by the pressing rod 170 and the lower end of the fixed blade 164 have the same height. That is, even when the thickness of the carrier tape differs depending on the type of the tape-making component 106, that is, even when the thickness of the residual tape 132 differs, the height of the bottom surface of the residual tape 132 pressed against the pressing surface 174. At, the movable blade 162 and the fixed blade 164 make sliding contact with each other, and the residual tape 132 is cut. Accordingly, even when the thickness of the residual tape 132 is different, the residual tape 132 is cut at a constant height, and the residual tape 132 can be stably cut.

Further, in the cutting device 128, the tape cutting mechanism 152 and the tape pressing mechanism 154 are operated in cooperation with each other by the air cylinder 156. That is, the tape cutting mechanism 152 and the tape pressing mechanism 154 operate in conjunction with each other by one drive source. As a result, the structure can be simplified, the cost can be reduced, and the control can be simplified.

The cutting device 128 cuts the remaining tape 132 at the timing when the feeding device 122 has finished feeding the tape-forming component 106, but the feeding device 122 feeds the tape-forming component 106 any number of times. The residual tape 132 is cut. Specifically, for example, when the housing recess 114 is large, that is, when the taped electronic component 110 is large, the tape forming component 106 is fed once by the feeding device 122 in order to reduce the remaining tape piece. Each time, the residual tape 132 is cut. On the other hand, for example, when the accommodation recess 114 is small, that is, when the taped electronic component 110 is small, the residual tape 132 is cut every time the feeding device 122 feeds the tape-forming component 106 a plurality of times.

The tape feeder 100 is an example of the tape feeder. The taped component 106 is an example of a taped component. The discharge path 126 is an example of a transport path. The remaining tape 132 is an example of the remaining tape. The tape cutting mechanism 152 is an example of a tape cutting mechanism. The tape pressing mechanism 154 is an example of the tape pressing mechanism. The air cylinder 156 is an example of a drive source. The fixed block 172 is an example of a pressing member.

Further, the present invention is not limited to the above-mentioned embodiments, but can be carried out in various modes with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, the pressing rod 170 presses the residual tape 132 from the lower side to the upper side, but the pressing rod may press the residual tape 132 from the upper side to the lower side. That is, the fixed block 172 may be arranged below the pressing rod 170, and the lower end of the pressing rod 170 may contact the fixed block 172 as the pressing rod 170 descends.

Further, in the above-described embodiment, the residual tape 132 is pressed against the fixed block 172 by the pressing rod 170 on the rear side of the movable blade 162 and the fixed blade 164, but the residual tape 132 is pressed on the front side of the movable blade 162 and the fixed blade 164. The tape 132 may be pressed against the fixed block 172 by the pressing rod 170. That is, the pressing rod 170 may be arranged on the front side of the movable blade 162, and the fixed block 172 may be arranged on the front side of the fixed blade 164.

In addition, in the above embodiment, the fixed block 172 is a separate body from the duct that is the discharge path for the residual tape 132, but it may be a single body.

Further, in the above-described embodiment, the tape feeder 100 that supplies the electronic component 110 from the tape-formed component 106 is adopted. However, the tape feeder that supplies the lead component such as the radial component or the axial component from the tape-formed component is adopted. Is also possible. That is, it is possible to employ a tape feeder that supplies parts from the taped parts regardless of the presence or absence of leads.
