An ACF attachment mechanism 35 that press-bonds a part of the ACF (see reference numeral 51 a in FIG. 2) of the ACF tape 51 onto the adhesion target member 52.

  Here, in the vicinity of the ACF adhering mechanism 35, a tape cutting mechanism 36 for making cuts (see reference numeral 51c in FIG. 2) at both end positions of the portion of the ACF 51a of the ACF tape 51 attached to the adhesion target member 52; A tape pull-out mechanism 37 is provided that pulls out the ACF tape 51 transported by the tape transport mechanism 15 by a required length to be attached onto the adhesion target member 52 and positions the ACF tape 51 on the adhesion target member 52. As shown in FIG. 2, the cutting of the ACF tape 51 by the tape cutting mechanism 36 is performed only on the ACF 51a and not on the cover tape 51b.

  The automatic collection mechanism 40 rotates the collection reel 41 and the collection reel 41 that conveys the ACF tape 51 in a state where the used ACF tape 51 is wound around a part of the outer circumferential groove (outer circumferential portion) 41a. A collection side drive shaft 42 and a collection box 44 for collecting the used ACF tape 51 conveyed by the collection reel 41 are provided. Here, as shown in FIG. 3, a vacuum suction portion 43 including a plurality of vacuum suction holes and the like is provided in the outer circumferential groove 41 a around which the ACF tape 51 is wound, of the collection reel 41. By switching the suction state of each vacuum suction portion 43 in conjunction with the rotation, only the portion located in the upper half of the recovery reel 41 in the outer circumferential groove 41a is always in the suction state.

  Next, operation | movement of the ACF sticking apparatus 10 which consists of such a structure is demonstrated.

  In the ACF sticking apparatus 10 shown in FIG. 1, the ACF tape 51 is unwound from the supply reel 12 that is rotationally driven by the supply-side drive shaft 13 by the supply mechanism 11, and the fixed rollers 16 and 17, the supply-side three-dimensional transport mechanism 18. Then, it is conveyed via the supply side movable roller 23 and the fixed roller 24 so as to be positioned on the adhesion target member 52 placed on the backup 34 of the tape crimping mechanism 33.

  More specifically, when the supply reel 12 is rotated in the direction shown in the drawing with the rotation of the supply side drive shaft 13 in a state where the ACF tape 51 is clamped by a tape clamp mechanism (not shown), the supply reel 12, the ACF tape 51 is unwound and the ACF tape 51 is transported via the tape transport mechanism 15 (in particular, the fixed rollers 16 and 17, the supply side three-dimensional transport mechanism 18 and the supply side movable roller 23). The ACF tape 51 is slackened. At this time, the supply-side movable roller 23 held by the supply-side movable roller holding mechanism 31 is raised by the action of a weight (not shown). Further, when the supply side movable roller 23 rises and reaches the upper limit position, the rotation drive of the supply side drive shaft 13 is stopped. At this time, the ACF tape 51 of a required length to be attached onto the adhesion target member 52 is temporarily unwound from the supply reel 12 of the supply mechanism 11, and between the supply reel 12 and the fixed roller 24. It is in the state stored in.

  In this state, the clamp of the ACF tape 51 is released by opening a tape clamp mechanism (not shown), and the ACF tape 51 is illustrated by the tape drawing mechanism 37 in a state where the rotational drive of the supply side drive shaft 13 is stopped. The supply-side movable roller 23 held by the supply-side movable roller holding mechanism 31 starts to descend, and the ACF tape 51 stored between the supply reel 12 and the fixed roller 24 is moved in the direction shown in the figure. Moving. As a result, when the supply-side movable roller 23 descends and reaches the lower limit position, the ACF to be pasted on the adhesion target member 52 in the ACF tape 51 is positioned on the adhesion target member 52.

  Then, in the tape crimping mechanism 33, the ACF attachment mechanism 35 is moved toward the adhesion target member 52 placed on the backup 34, and the ACF tape 51 positioned on the adhesion target member 52 is pressed, whereby the ACF tape A portion of the ACF 51 (reference numeral 51 a in FIG. 2) to be pasted is pressed onto the adhesion target member 52. At this time, the tape cutting mechanism 36 cuts the both ends of the portion of the ACF 51 a of the ACF tape 51 that is attached to the adhesion target member 52 at a predetermined timing.

  Here, the used ACF tape 51 in which only the cover tape 51b is left by the pressure bonding of the ACF 51a is conveyed via the fixed roller 25, the collection-side movable roller 26, and the collection-side three-dimensional conveyance mechanism 27, Finally, it is collected by the automatic collection mechanism 40.

  More specifically, when the recovery reel 41 is rotated in the direction shown in the drawing with the rotation of the recovery drive shaft 42 in a state where the ACF tape 51 is clamped by a tape clamp mechanism (not shown), the recovery reel 41 conveys the ACF tape 51 in a state where the used ACF tape 51 is wound around a part of the outer peripheral groove 41a. That is, the collection reel 41 is switched to the suction state of each vacuum suction portion 43 in conjunction with its rotation so that only the portion located in the upper half of the collection reel 41 in the outer circumferential groove 41a is always in the suction state. The used ACF tape 51 that is attracted and fixed to the outer peripheral groove 41a of the recovery reel 41 on the upstream side is transported by a predetermined length less than one round, and then a predetermined separation position (on the downstream side) They are separated at reference R in FIG. As a result, the used ACF tape 51 separated from the collection reel 41 at the separation position of the outer circumferential groove 41a (see symbol R in FIG. 3) is vertically moved by its own weight (the moving direction of the collection-side movable roller 26). And is finally collected by the collection box 44. The used ACF tape 51 wound around the collection reel 41 is a surface of the cover tape 51b included in the ACF tape 51 on the side to which the ACF 51a is not attached (the upper surface of the cover tape 51b shown in FIG. 2). ) Is in contact with the outer peripheral groove 41a of the recovery reel 41.

  In the process in which the used ACF tape 51 is collected by the automatic collection mechanism 40 as described above, a downward pulling force is generated on the used ACF tape 51. As a result, the collection-side movable roller 26 held by the collection-side movable roller holding mechanism 32 descends against the pulling force applied upward by the action of a weight (not shown). When the collection-side movable roller 26 is lowered and reaches the lower limit position, the rotation drive of the collection-side drive shaft 42 is stopped.

  In this state, the ACF tape 51 is released by releasing the tape clamp mechanism (not shown), and the ACF tape 51 is released by the tape drawing mechanism 37 in a state where the rotation drive of the collection side drive shaft 42 is stopped. Is pulled out in the direction shown in the figure, the used ACF tape 51 to be collected by the automatic collection mechanism 40 is slackened, and the collection-side movable roller 26 is raised by the action of a weight (not shown). When the ACF tape 51 corresponding to the required length to be stuck on the adhesion target member 52 is pulled out by the tape pulling mechanism 37, the collection-side movable roller 26 reaches the upper limit position.

  As described above, according to the present embodiment, the used ACF tape 51 is wound around a part of the outer peripheral groove 41a by the collecting reel 41 rotated by the collecting drive shaft 42. After transporting 51, the ACF tape 51 is pulled away at a predetermined separation position (see reference numeral R in FIG. 3) on the downstream side of the recovery reel 41, and the vertical direction (moving direction of the recovery-side movable roller 26) by its own weight. ) And is finally collected by the collection box 44, so that the operation of the apparatus can be improved without the need to replace the collection reel 41.

  Further, according to the present embodiment, the used ACF tape 51 wound around the collection reel 41 has a surface of the cover reel 51 b included in the ACF tape 51 on the side where the ACF 51 a is not attached. Since it is wound while being in contact with the outer peripheral groove 41a, it effectively prevents the ACF remaining on the used ACF tape 51 from adhering to the recovery reel 41 and the like, thereby eliminating the need for maintenance. can do.
