Description

  The present invention relates to a component supply device that supplies a component to a component mounting apparatus that mounts an electronic component or the like on a substrate, and more particularly, to a component supply device that supplies a component using a component supply tape in which the electronic component or the like is stored.

  As a component supply device that supplies components to an electronic component surface mounting device, a component supply device that supplies components using a component supply tape that stores electronic components or the like is generally used.

  As shown in FIG. 1, the component supply tape T includes a carrier tape (tape body) T1 having a storage recess T1A for storing components, a component P stored in the storage recess T1A, and a storage in which the component P is stored. The cover tape T2 covers and encloses the recess T1A. The storage recesses T1A for storing the components P are arranged at regular intervals, and the components P are accommodated in the component supply tape T at regular intervals. The carrier tape (tape body) T1 is provided with a feed hole T1B for feeding the tape. The component supply tape T is held in a state of being wound around a reel. The reel that holds the component supply tape T may be provided separately from the component supply device, or may be included in the component supply device.

  The carrier tape (tape main body) T1 of the component supply tape T is provided with feed holes T1B having the same interval as the interval between the storage recesses T1A, that is, the interval between the stored electronic components P. By rotating a sprocket having a pin that engages with the feed hole T1B, the pin of the sprocket pulls the carrier tape (tape body) T1 through the feed hole, and the carrier tape (tape body) T1 is pulled to a predetermined tape. It is sent out to the peeling part and the parts supply part. The sprocket is a component in which pins that engage with the feed holes are radially arranged on the outer periphery of a disk-shaped flat plate.

  The component supply tape T is led out from the reel, and is guided to the tape peeling portion through a path in the component supply device. In the tape peeling portion, the cover tape T2 is folded back and pulled in the direction opposite to the traveling direction of the carrier tape (tape body) T1, and the cover tape T2 is peeled off and separated from the carrier tape (tape body) T1. Is ready to be removed. A component supply portion opened upward is disposed at a point where the carrier tape (tape main body) T1 slightly advances downstream from the tape peeling portion, and the cover tape T2 is peeled off at the component supply portion. The exposed component P is picked up and taken out by the component transfer head of the electronic component surface mounting apparatus under vacuum pressure.

  The cover tape T2 peeled off from the carrier tape (tape body) T1 follows a path different from that of the carrier tape (tape body) T1 and is collected as waste, and the carrier tape (tape body) T1 is also discarded as waste. Collected.

  The method of collecting the cover tape T2 differs depending on the component supply device. However, as described in FIG. 1 of Patent Document 1, the method of collecting the cover tape T2 in a container provided outside the device, and the column of the conventional technique of Patent Document 2 There are a method of winding on a reel as described in FIG. 3, a method of collecting in a recovery box arranged in the apparatus as described in FIG.

  However, in the component supply apparatus 100 including the recovery box 110 for recovering the cover tape T2, when the amount of the cover tape T2 accumulated in the recovery box 110 increases, the idler gear 118 is used when scraping the cover tape T2. In some cases, slippage occurs between the drive gear 120 and a normal scraping operation cannot be performed. As schematically shown in FIG. 6, in the vicinity of the entrance 110 </ b> A of the recovery box 110, the cover tape T <b> 2 accumulated in the recovery box 110 applies a force to push up the wrapping prevention member 124, and the arm 114 is lifted. Was the cause.

  The present invention has been made in view of such a problem, and in a component supply apparatus equipped with a recovery box for recovering a cover tape, the cover tape is provided even if the amount of the cover tape accumulated in the recovery box increases. It is an object of the present invention to provide a component supply apparatus that can normally scrape a cover tape without slipping between a pair of rotating bodies that are scraped and fed into a collection box.

  The present invention provides a recovery box for recovering a cover tape enclosing components housed in a plurality of storage recesses arranged in a row in a row after recovering the component, and scraping the cover tape after extracting the component to recover the recovery tape. A pair of rotating bodies to be fed into the box, each of the pair of rotating bodies having a continuous circumferential groove on the outer peripheral surface, and one rotating body of the pair of rotating bodies is the other rotating body In the component supply device provided with a wrapping preventing member that further enters the groove of the urged one of the rotating bodies and prevents the cover tape from being wound after the component is taken out. The anti-winding member is fixed to the main body frame of the component supply device, and the anti-winding member has a shape along the outer peripheral surface of the urged one rotating body. The component feeding device which is a circular arc shape which enters into the groove of the rotating body, is intended to solve the above problems.

  According to the present invention, the wrapping preventing member for preventing wrapping is fixed to the main body frame of the component supply device, so that the cover tape accumulated in the collection box applies a force to push up the wrapping preventing member. However, the engagement between the pair of rotating bodies scraping out the cover tape and feeding it into the collection box does not become shallow, and the cover tape is prevented from slipping.

  For this reason, more cover tapes can be stored in the same collection box than before, and the number of times the cover tape is taken out and discarded from the collection box can be reduced.

  Further, since the shape of the anti-winding member is an arc shape that enters the groove of the one rotating body along the outer peripheral surface of the one rotating body that is biased, the cover is interposed between the pair of rotating bodies. When the tape is passed, the arc-shaped outer peripheral surface serves as a guide, so that the cover tape can be passed more smoothly than before.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. Since the feature of the present invention lies in the cover tape scraping mechanism section, the cover tape scraping mechanism section will be mainly described. For the same components as those of the conventional component supply apparatus 100, the reference numerals used in the description of the conventional component supply apparatus 100 are used as they are, and the description thereof is omitted.

  FIG. 7 is a side view showing the wrapping preventing member 10 alone of the component supply apparatus according to the embodiment of the present invention. FIG. 8 is an enlarged side view of the vicinity of the anti-winding member in a normal state in which the tip of the arm 12 is lowered in the component supply apparatus of the present embodiment, and FIG. 9 is a winding in a state in which the tip of the arm 12 is raised. It is an enlarged side view of the vicinity of a sticking prevention member.

  The wrapping prevention member 10 includes a claw member 10A and a block portion 10B, and the claw member 10A is attached and fixed to the block portion 10B. Note that the claw member 10A and the block portion 10B may be integrally formed. The block portion 10 </ b> B is fixed to the main body frame 102 by the two joining members 12, whereby the anti-winding member 10 is fixed to the main body frame 102. The anti-winding member 10 is disposed above the entrance which is an opening of the recovery box 110, and the lower surface of the anti-winding member 10 forms an accommodation space for accommodating the cover tape T2 together with the inner surface of the recovery box 110. is doing. A through hole 14 is provided in the central portion of the block portion 10B, and this through hole 14 is for passing a rotating shaft 116 for rotatably mounting the arm 16 to the main body frame 102. .

  Even if the amount of the cover tape T2 accumulated in the collection box 110 increases and the cover tape T2 collected in the collection box 110 applies a force to push up the wrapping prevention member 10, in this embodiment, the wrapping prevention member 10 Is fixed to the main body frame 102, the arm 16 is not pushed up, and it is possible to prevent the cover tape T2 from slipping due to shallow engagement between the idler gear 118 and the drive gear 120. For this reason, in the component supply apparatus of this embodiment, more cover tapes T2 can be stored in the same collection box 110 than before, and the number of times the cover tape T2 is taken out from the collection box 110 and discarded is reduced. Can do. When an actual surface mounting operation was performed using the component supply apparatus of this embodiment, the amount of the cover tape T2 stored in the same collection box 110 was about twice that of the conventional case.

  Next, as for the claw member 10A, like the conventional claw member 124A, it has a role of preventing the cover tape T2 from being wound around the idler gear 118 by entering into the groove of the idler gear 118. The shape of the claw member 10A is an arc shape that follows the shape of the idler gear 118, and is greatly different from the shape of the conventional linear claw member 124A.

  Here, when the cover tape T2 is first passed between the idler gear 118 and the drive gear 120, the rear end portion of the arm 114 is pushed down by hand so that a gap is formed between the idler gear 118 and the drive gear 120. The cover tape T <b> 2 is passed through the gap. In the case of the component supply device of this embodiment, the anti-winding member 10 is attached and fixed to the main body frame 102, so the anti-winding member 124 is attached to the arm 114. The anti-winding member 10 does not rise in accordance with the rise of the idler gear 118 as in the conventional component supply apparatus 100. For this reason, even if the idler gear 118 is raised, the claw member 10A of the anti-winding member 10 is located between the idler gear 118 and the drive gear 120, so that the cover tape T2 cannot be smoothly passed. There is concern about whether there is.

  However, since the shape of the claw member 10A is an arc shape that follows the shape of the idler gear 118, when the cover tape T2 is passed as shown in FIG. Absent. Rather, the cover tape T2 can be passed along the shape of the arcuate outer peripheral surface of the claw member 10A, and the arcuate outer peripheral surface of the claw member 10A serves as a guide. Can pass through.

  In the component supply apparatus according to the embodiment of the present invention described above, the anti-winding member 10 is fixed to the main body frame 102 with the joining member 12, but the anti-winding member 10 is formed integrally with the main body frame 102. , May be integrated.

  Further, the idler gear 118 and the drive gear 120 that scrape the cover tape T2 and send it into the collection box 110 have teeth on the outer peripheral surface, but instead of the idler gear 118 and the drive gear 120, a circle without teeth. An idler roller and a drive roller whose peripheral surface is the outer peripheral surface may be used.

  4B, the number of the grooves 118A of the idler gear 118 is two. However, in both the idler gear 118 and the drive gear 120, the number of the grooves 118A and the grooves 120A is not limited to two. One may be sufficient and three or more may be sufficient. Further, the number of claws of the claw member 10A of the wrapping prevention member 10 is not limited to two, and may be one or three or more as long as it corresponds to the position of the groove 118A. Also good.

  Although it is conceivable to attach and fix the conventional anti-winding member 124 to the main body frame 102, the shape of the claw member 124 </ b> A of the conventional anti-winding member 124 is linear, so the conventional anti-winding member 124. Is attached to the main body frame 102 instead of the arm 114, as shown in FIG. 10, when the cover tape T2 is passed, the tip of the claw member 124A becomes in the way and cannot be used.
