Description

  The present invention relates to a processing device for a top tape constituting a taped electronic component, and more particularly to a top tape processing device suitable for processing a top tape of a taped electronic component supplied endlessly.

  Supplying an electronic component as a taped electronic component to an electronic component mounting apparatus or the like is widely performed. In the taped electronic component, an electronic component is accommodated in each of a large number of electronic component receiving recesses formed at equal intervals in the longitudinal direction of the component holding tape, and the opening of the electronic component receiving recess is blocked by a top tape. Often consists of This type of taped electronic component includes a taped electronic component in which an electronic component receiving recess is formed in the central portion in the width direction of a thick component holding tape, and a central portion in the width direction of a component holding tape made of a thin material. There is a so-called embossed type taped electronic component in which an electronic component receiving recess is formed in an electronic component receiving portion that protrudes downward in a container shape. The embossed-type taped electronic component includes a supported portion that extends in the longitudinal direction on both sides in the width direction of the component holding tape, and a large number of electronic component housing portions that protrude downward from the supported portions between the two supported portions. Will be provided.

The taped electronic component is wound around a supply reel, set in an electronic component supply cartridge, and supplied to an electronic component take-out device such as an electronic component mounting device. The electronic component supply cartridge is provided with a feeding device for feeding the taped electronic component and a top tape winding device for winding the top tape. The top tape take-up device includes, for example, a take-up reel and a take-up reel rotating device that is mechanically connected to the take-up reel. The top tape is pulled by the rotation of the take-up reel, peeled off from the component holding tape, and wound on the take-up reel. It is supposed to take.
Conventionally, once there is no taped electronic component in the electronic component supply cartridge, supply is temporarily stopped, an empty supply reel is removed, a new supply reel is set, and a take-up reel is replaced. It was. The electronic component supply cartridge is removed from the cartridge support, and the take-up reel and the take-up reel rotating device are disconnected to replace the take-up reel.

  However, if the supply of electronic components is stopped and the supply reel and the take-up reel are replaced, the supply efficiency is lowered. As the number of types of electronic components increases and the number of electronic component supply cartridges increases, the stop time increases, and it is inevitable that the operating rate of the electronic component take-out device for taking out the electronic components such as the electronic component mounting device is reduced.

This problem can be solved if the taped electronic components are supplied endlessly. A taped electronic component that is attached to an electronic component supply cartridge and is currently supplying electronic components, and a new taped electronic component that is then attached to the electronic component supply cartridge and supplies electronic components are connected using a connection tape. They are connected together. If the electronic components are supplied endlessly by connecting the taped electronic components in this way, the top tape peeled off from the component holding tape becomes endless. The device cannot handle it. This is because in order to release the connection between the take-up reel and the take-up reel rotating device, the take-up must be stopped and the supply of electronic components must be interrupted. Will disappear.
An object of the present invention is to provide a top tape processing apparatus that makes it possible to supply electronic components endlessly.

In order to solve the above-mentioned problem, the invention according to claim 1 of the present application accommodates electronic components in a large number of electronic component receiving recesses formed at equal intervals in the longitudinal direction of the component holding tape. The opening of the housing recess is closed by the top tape, and the top tape peeled off from the component holding tape of the taped electronic component fed in the feeding direction is twisted by approximately 90 degrees in the posture of the taped electronic component. The top tape processing device that passes from the upper side to the lower side of the supply path has a tapered frustoconical shape with a tapered outer peripheral surface, and the taped electronic component is mounted on a flat mounting plate by a support shaft perpendicular to the mounting plate. The taper outer peripheral surface is attached as a side of the attachment plate so that it can rotate around a center line parallel to the width direction of the tape. While changing along the tapered outer circumferential surface top tape twisting torsion roller including Mutotomoni supply path of the carrier tape at the side opposite to the said top tape the small-diameter side of the tapered outer peripheral surface It is characterized in that it is allowed to pass through.
The torsion roller may be (i) one provided above the taped electronic component supply path (first torsion roller) or (ii) one provided below (second torsion roller) Or (iii) both torsion rollers provided on the upper side and the lower side, and the modes (i) and (iii) are the modes according to the invention of claim 2.

  The top tape can be discharged downward and accommodated in a container. However, when the top tape is peeled off from the component holding tape, the taped electronic component being fed forward in a substantially horizontal posture is folded back to the top tape side that has not yet been peeled off from the component holding tape, that is, the tape is peeled off. The applied top tape is above the taped electronic component. Therefore, the top tape can be discharged downward without crossing the taped electronic component being supplied if the taped electronic component container such as a supply reel that accommodates the taped electronic component and sequentially feeds it is moved backward. However, it is unavoidable that the discharge path becomes longer and the apparatus becomes larger. It is desirable that the top tape is discharged in the lower direction across the taped electronic component in front of the taped electronic component container. However, if the top tape is crossed with the taped electronic component in a posture in which the width direction of the top tape is parallel to the width direction of the component holding tape, a space of at least the sum of the width of the component holding tape and the width of the top tape is obtained. As a result, the width of the electronic component supply cartridge including the top tape processing device becomes wide, and the arrangement pitch of the electronic component supply cartridge cannot be reduced. On the other hand, in the top tape processing apparatus according to the present invention, the top tape is twisted by approximately 90 degrees and passed through the side of the taped electronic component. If the top tape is twisted approximately 90 degrees, a portion that is substantially perpendicular to the width direction of the taped electronic component is generated on the top tape. Becomes narrower.

  The taped electronic component is supplied in a substantially horizontal posture at the tip portion supplying the electronic component, but may be supplied in a horizontal posture between the tip portion and the taped electronic component container. The taped electronic component feeding direction may be supplied in a posture in which the upstream side is above the downstream side and is directed obliquely downward, or conversely, may be supplied in a posture directed obliquely upward. In either case, the top tape can be passed through a narrow space on the side of the taped electronic component by twisting the top tape by approximately 90 degrees.

In addition, it includes a torsion roller that has a truncated cone shape and is rotatable around a center line parallel to the width direction of the taped electronic component. The torsion roller twists the top tape and changes its direction. The top tape is redirected along the tapered outer peripheral surface of the torsion roller, and is accordingly moved from the smaller diameter side of the torsion roller to the larger diameter side. Therefore, if the top tape twisted 90 degrees is allowed to pass through one side of the taped electronic component on the side opposite to the side where the diameter of the twisting roller is small, the top tape is twisted around the taper circumference of the twisting roller. You can follow the surface without difficulty.
Also, if the top tape is bent in the thickness direction of the top tape before it is twisted, the taped electronic component between the component supply portion of the electronic component supply cartridge and the taped electronic component container is horizontally or obliquely upward. The top tape can be crossed with the taped electronic component even when it is extended in a posture facing toward. Further, since the torsion roller guides the top tape while rotating, the frictional force between the torsion roller and the top tape can be reduced. In particular, when the top tape peeling device also serves as a device that passes the top tape guide device and feeds the top tape, the top tape can be peeled smoothly.

If the top tape peeled off from the component holding tape as described above is twisted to cross the taped electronic components and discharged downward, the top tape may be left peeled off, Thus, there is no need to replace the take-up reel as described above, and a top tape processing device can be obtained that does not hinder endless supply of taped electronic components and can make the electronic component supply cartridge compact. Further, a take-up reel and a take-up reel rotating device are not required, and a top tape processing device with a simple configuration can be obtained. The electronic component supply cartridge is usually provided with a container for accommodating an empty component holding tape from which the electronic component has been taken out. If the top tape is accommodated in this container, the structure is further increased. A simple top tape processing apparatus can be obtained.
As described above, the present invention was made for the purpose of obtaining a top tape processing apparatus suitable for processing the top tape of taped electronic components supplied endlessly. The processing apparatus is also effective when used for processing the top tape of a normal taped electronic component that is not supplied endlessly.

  The top tape 24 drawn out from the slit of the cover 220 is hung on the guide roller 420 and then wound on the first twisting roller 424 from above. Since the first torsion roller 424 has a truncated cone shape, the top tape 24 is twisted by 90 degrees, and the direction is changed from a substantially horizontal state to an obliquely downward direction, so that the guide pieces 434 and 434 of the guide members 410 and 412 are changed. The outer side of 436 is passed in a state twisted 90 degrees. The top tape 24 is disposed avoiding interference with the guide members 410 and 412, and does not interfere with the taped electronic component 20 passing over the guide member 412.

  Further, the top tape 24 is wound around the second twisting roller 430 from above. Since the second twisting roller 430 is inclined in the same direction as the first twisting roller 424, the top tape 24 is moved in the direction opposite to the direction twisted by the first twisting roller 424. Twisted. As a result, the drive peeling roller 442 and the driven peeling roller 444 of the top tape peeling device 440 provided below the guide member 412 enter the lower side of the guide member 412 from the side of the guide member 412. Between.

  The top tape 24 is pulled when the drive peeling roller 442 is rotated when the taped electronic component 20 is fed, and is peeled off from the component holding tape 22. Then, the top tape 24 that has passed between the driving peeling roller 442 and the driven peeling roller 444 is accommodated in a tape container that accommodates an empty component holding tape 22.

The top tape 24 is wound around the first twisting roller 424 from the upper side, and after being twisted by 90 degrees, the top tape 24 is wound around the second twisting roller 430 from the upper side and is twisted back by 90 degrees. The first and second torsion rollers 424 and 430 come into contact with the surface of the top tape 24 opposite to the pasting surface that has been pasted on the component holding tape 22, and the adhesive remains on the pasting surface. However, the top tape 24 does not stick to the first and second twisting rollers 424 and 430 to prevent the top tape peeling device 440 from peeling.
Further, the driven peeling roller 444 of the top tape peeling device 440 is in contact with the sticking surface of the top tape 24, but since the outer peripheral surface of the driven peeling roller 444 is provided with a sharp pointed tip, Even if the adhesive remains, it is difficult to stick, and even if it is stuck, it is separated from the driven peeling roller 444 by the separating portion 452 provided on the lever 450, and the top tape 24 is not wound around the driven peeling roller 444.
The top tape 24 wound around the first and second twisting rollers 424 and 430 tends to shift from the larger diameter side to the smaller side in the axial direction of the rollers 424 and 430. Disengagement from the second twisting rollers 424 and 430 is prevented by the mounting plate 404.

When the electronic component 26 is supplied, the component suction head 256 is moved in the X and Y directions, positioned on the electronic component extraction position of the cartridge 400 that supplies the electronic component, and then lowered to take out the electronic component 26. . In the cartridge 400, the taped electronic component 20 is sent in preparation for the supply of the electronic component 26, and the leading electronic component 26 from which the top tape 24 has been peeled is positioned at the electronic component take-out position while being covered by the shutter 260. ing. The shutter 260 is at the forward end position.

  When the component suction head 256 is lowered, the engagement member 210 of the engagement device 200 provided for the cartridge 400 from which the electronic component 26 is taken out is moved to the engagement position, and the slider 184 of the drive device 180 is retracted. It is done. As a result, the rotating plate 146 is rotated in the opposite direction, the ratchet pawl 148 gets over the teeth 154 of the ratchet wheel 144 and preparation for feeding is made, and the shutter 260 is rotated along with the rotation of the rotating plate 146. It is moved to the backward end position.

  When the rotating plate 146 is rotated in the reverse direction, the ratchet wheel 144 is not rotated, so that the taped electronic component 20 is not sent, and only the shutter 260 is retracted from the forward end position to the backward end position, and the flying The ejection preventing piece 276 is retracted from the electronic component 26 positioned at the electronic component extraction position. As shown in FIG. 8, the slit 250 is provided upstream of the slit 278 in the taped electronic component feeding direction, and the top tape 24 drawn out from the slit 250 does not interfere with the pop-out preventing piece 276. .

  The component suction head 256 is lowered at a timing when it comes into contact with the electronic component 26 after the pop-out prevention piece 276 has been retracted to a position outside the entire electronic component, and sucks the electronic component 26. After suction, the component suction head 256 is raised and moved in the X and Y directions, and the electronic component 26 is mounted on a mounting target member such as a printed circuit board.

  In the cartridge 400, after the electronic component 26 is taken out, the taped electronic component 20 is sent. The slider 184 of the driving device 180 is moved forward, and the rotating plate 146 is rotated in the forward direction. At this time, the shutter 260 is moved together with the taped electronic component 20 from the retracted end position to the advanced end position. Among the electronic components 26 from which the top tape 24 has been peeled off, the leading electronic component 26 is sent to the electronic component take-out position in a state where the electronic component receiving recess 28 of the shutter 260 prevents the electronic component receiving recess 28 from jumping out. It is.

  The pop-out preventing portion 274 has such a length that the rear end portion is kept overlapped with the cover 220 even when the shutter 260 is moved to the forward end position, so that the top tape 24 is peeled off. Until the electronic component 26 accommodated in the electronic component accommodating recess 28 is adsorbed by the component adsorbing head 256, the electronic component 26 is ejected by at least one of the fixed jump preventing surface 240 of the cover 220 and the movable jump preventing surface 279 of the shutter 260. It is prevented from taking out.

  When the supply of the electronic component 26 proceeds and the taped electronic component 20 wound around the supply reel 32 is lost, the operator is informed that the taped electronic component 20 is lost based on the detection by the tape end detection device 40, Based on this, the operator replenishes the taped electronic component 20. The terminal portion of the taped electronic component 20 is not fixed to the supply reel 32, and is naturally removed from the supply reel 32 and detected by the tape end detection device 40. The operator removes the supply reel 32 from which the taped electronic component 20 has disappeared, sets the supply reel 32 that supplies the taped electronic component 20, and then supplies the electronic component 26. The connecting tape 390 shown in FIG. 12 is connected to the end of the tape and the starting end of the taped electronic component 20 that supplies the electronic component 26 next.

  The connection tape 390 is narrower than the width of the portion excluding the portion where the feed hole 30 of the taped electronic component 20 is formed, and an adhesive is applied to one surface. The connection tape 390 is made of synthetic resin and is attached to a thin and transparent tape holding sheet 392. The tape holding sheet 392 has a width and a thickness necessary and sufficient for holding the taped electronic component 20, and a plurality of tape holding sheets 392 are provided at positions corresponding to portions where the feed holes 30 of the taped electronic component 20 are formed in the width direction. The positioning protrusions 394 are formed at a pitch equal to the formation pitch of the feed holes 30. Adhesive is applied to the surface of the tape holding sheet 392 on which the positioning projection 394 is projected, and the connection tape 390 is disposed at a position that is substantially the center in the width direction and does not interfere with the positioning projection 394. It is affixed on the surface opposite to the affixing surface where the agent is applied. The attachment surface of the connection tape 390 is covered with a cover sheet (not shown).

The connecting tape 390 has a length sufficient to connect the two taped electronic components 20. At the time of connecting the taped electronic component 20, the cover sheet covering the connection tape 390 is peeled off, and the surface on the component holding tape 22 side of the terminal portion of the taped electronic component 20 that is actually supplying the electronic component 26 is The feeding hole 30 is fitted on a positioning projection 394 provided on the tape holding sheet 392, while being placed on the sticking surface on the almost half side in the longitudinal direction. Next, the surface on the component holding tape 22 side of the starting end portion of the taped electronic component 20 that supplies the electronic component 26 next is opposite to the taped electronic component 20 that is actually supplying the electronic component 26 in the longitudinal direction. From the side, it is placed on the remaining sticking surface of the connection tape 390 and the feed hole 30 is fitted into the positioning protrusion 394.
The end edge of the taped electronic component 20 that actually supplies the electronic component 26 and the start edge of the taped electronic component 20 that supplies the electronic component 26 next are the two taped electronic components 20 closest to each other. When the feed hole 30 is fitted to the positioning protrusion 394 in a state where the electronic component is received, the distance between the last electronic component receiving recess 28 and the leading electronic component receiving recess 28 is equal to the formation interval of the electronic component receiving recess 28. Has been disconnected by the operator.

  Next, another connecting tape 390 is fitted on the surface of the two taped electronic components 20 on the top tape 24 side, the positioning protrusions 394 are fitted into the feed holes 30, and the end portions of the two taped electronic components 20 are connected. Paste in a state that straddles and the start. The two connection tapes 390 held by the tape holding sheet 392 sandwich the terminal and starting ends of the two taped electronic components 20 from both sides in the thickness direction. If the tape holding sheet 392 is taken in this state, the two taped electronic components 20 are connected in a state of being sandwiched by the connecting tape 390 from both sides in the thickness direction. The connection of the two taped electronic components 20 is performed without stopping the supply of the electronic components 26 by the electronic component supply apparatus 10, and the electronic components 26 can be supplied endlessly.

  On the other hand, since the top tape 24 is not wound around the take-up reel and is accommodated in the tape container, there is no processing performed on the top tape 24, and the supply of the taped electronic component 20 is performed without stopping the supply of the electronic component 26. It is only necessary to do this, and the work can be performed easily and quickly. The tape container is large, and it is sufficient to discard the tape at an appropriate time, for example, when the supply of the electronic component by the electronic component supply device is finished and the supply is stopped. There is no need to throw away every time.

  Further, since the first and second torsion rollers 424 and 430 are provided at a distance in the feeding direction of the taped electronic component 20, the taped electronic component 20 has a horizontal orientation in the direction of the top tape 24. The downward conversion is performed slowly, and the top tape 24 is less likely to lift from the first and second twisting rollers 424 and 430, and the driving peeling roller 442 and the driven peeling roller 444 twist the top tape 24. Although it pulls after twisting, the top tape 24 can be pulled smoothly.

  In this embodiment, the cartridge 400 is a twin cartridge 42 in which two cartridges are integrally provided, and the width per cartridge can be reduced as compared with the case where they are provided separately. For example, the two cartridges 400 share the mounting plate 404 constituting the cartridge main body 402 and support the support shaft of the support peeling roller 444 and the support shaft that rotatably supports the drive peeling roller 474 of each cartridge 400. One of the shafts functions as a male screw portion and the other as a female screw portion, and is fixed to the mounting plate 404. Compared to the case where the support shaft is fixed to the mounting plate by separate male screw portions and nuts, respectively. The number of parts can be reduced, and a space for disposing the male screw portion and the nut is unnecessary, and the width can be reduced. The cover 181 is fixed to one cartridge 400 of the two cartridges 400, but for the other cartridge 400, one cartridge 400 functions as the cover 181, and also in this respect, the width of the cartridge 400 is narrowed. be able to.
