  Next, based on FIGS. 1 and 2, another embodiment of the peeling apparatus for a workpiece with a thin adhesive according to the present invention will be described in detail. This embodiment has a structure in which a strong pressurizing force can be applied to the peeling tape 11, and a stronger tension can be generated by pulling the peeling tape 11 with a stronger force. Thereby, the peeling tape 11 can be appropriately and reliably bent at the peeling portion 21 formed in the spatula shape, and the workpiece 10 can be suitably peeled from the peeling tape 11.

  According to this embodiment, the reciprocating movable unit 20 includes a movable main body 22 having a peeling portion 21 and a portion to which a pair of movable pulleys 25 and 25 are attached so that a stronger pressurization can be applied. And a movable pulley mounting portion 23 attached to the movable main body 22 so as to be able to reciprocate in parallel with the feeding direction of 11A and to apply tension to the peeling tape 11 by the elastic member 24. As the elastic member 24, for example, a coil spring can be used as shown in each drawing. However, the elastic member 24 is not limited to this, and a device that generates a spring property such as a disc spring or a leaf spring, or a cylinder device or an electric actuator is used. May be.

As shown in FIG. 2, pressurization can be applied to the peeling tape 11 by compressing the elastic member 24 by bringing the movable main body 22 of the reciprocating movable unit 20 into contact with the stopper 70.
According to this, when the workpiece 10 is peeled off at the peeling portion 21, the elastic member 24 moves the reciprocating movable unit 20 in the direction in which the peeling tape 11 is wound (from right to left in the drawing). A pressure is applied to the peeling tape 11. In this state, in addition to the pressurization by the brake part 33, the pressurization by the elastic member 24 is applied, and a strong tension is applied by the peeling tape 11.

  Next, based on FIG.1 and FIGS.3-8, the action | operation process of the form example of the peeling apparatus of the workpiece | work with a thin adhesive concerning this invention is demonstrated in detail.

  In the first operation process of FIG. 1, the peeling tape 11 is chucked and held by the fixed chuck 32 on the peeling tape discharge side, and is sandwiched and held by the brake portion 33, so that pressure is applied to the peeling tape 11. It is in a suspended state. Thereby, the peeling tape 11 is bent in a state of being stretched at the spatula portion of the peeling portion 21. The feeding of the peeling tape 11 is stopped.

  In the second operation step of FIG. 3, the tape material 11A is chucked and held by the fixed chuck 31 on the tape material supply side while the release tape 11 is held by the fixed chuck 32 on the release tape discharge side, and the feed is performed. The peeling tape 11 is chucked and held by the chuck 60. Specifically, as shown in the figure, the release tape 11 is held by operating the chuck piece A of the fixed chuck 31 on the tape material supply side and operating the chuck piece B of the feed chuck 60.

  In the third operation step of FIG. 4, the chuck piece C of the fixed chuck 32 on the release tape discharge side is operated and opened to release the holding of the release tape 11.

In the fourth operation step of FIG. 5, the drive device 41 is operated to rotate one fixed pulley 40 to one side. In the drawing, as indicated by an arrow, one fixed pulley 40 is rotated counterclockwise. According to this, the reciprocating movable unit 20 is moved in the discharge direction of the peeling tape 11 via the pair of movable pulleys 25, 25 (see arrow), and the peeling tape 11 held by the feed chuck 60 of the interlocking body 55. Can be sent while being moved in the discharge direction in synchronization (see arrows). Since the configuration of the present embodiment is a moving pulley mechanism, the reciprocating movable unit 20 (peeling portion 21 is compared with the feed length of the hanging member 50 by one fixed pulley 40 and the feed length of the peeling tape 11. ) Travel length is halved. This is a kind of speed reduction mechanism and can be controlled to a more precise operation. Further, in the case of a drive mechanism that is operated by meshing a timing belt and a timing pulley, play can be eliminated by applying a preload, and operation accuracy can be improved. In this embodiment, the elastic member 24 does not function, and the movable main body 32 and the movable pulley mounting portion 23 are integrated to operate as the reciprocating movable unit 20.
According to this operation process, the peeling tape 11 is moved in the discharging direction of the peeling tape so that the peeling portion 21 also moves backward while feeding the peeling tape 11 in the discharging direction. Meanwhile, the workpiece 10 is gradually peeled off from the peeling tape 11 while remaining in the same position. Therefore, as described above, the workpiece 10 is peeled from the peeling tape 11 in a state where positioning is easy.

  In the fifth operation step of FIG. 6, the chuck piece C of the fixed chuck 32 on the release tape discharge side is operated and chucked to hold the release tape 11.

  In the sixth operation step of FIG. 7, the chuck piece A of the fixed chuck 31 on the tape material supply side is operated and opened to release the holding of the tape material 11A. Further, the chuck piece B of the feed chuck 60 is operated and opened to release the holding of the peeling tape 11.

In the seventh operation step of FIG. 8, the drive device 41 is operated to rotate one fixed pulley 40 to the other. In the drawing, as indicated by an arrow, one fixed pulley 40 is rotated in the clockwise direction. According to this, the reciprocating movable unit 20 is moved in the supply direction of the tape material 11A via the pair of movable pulleys 25, 25 (see the arrow), and the feed chuck 60 of the interlocking member 55 is synchronized to the peeling tape. 11 is moved in the direction opposite to the discharging direction (see arrow).
According to this operation process, while the tape material 11A is fed in the supply direction, the peeling portion 21 is also moved in the same direction synchronously, and the tape material 11A is fed out from the feed reel 15 in accordance with this operation. At this time, a pressure is applied to the tape material 11 </ b> A by the brake portion 33, and the tape material 11 </ b> A is fed out in a state where the release tape 11 is suitably stretched.
When this operation is completed, the process returns to the first operation step, and one cycle of the operation by this apparatus is completed. And the workpiece | work 10 can be peeled suitably one by one by repeating this cycle sequentially.

According to the embodiment of the peeling device for the workpiece with the thin adhesive described above, the reciprocating movable unit 20 (peeling) is performed by one driving mechanism (one driving device) using a moving pulley mechanism that operates the hanging member 50. The movement of the part 21) and the feeding of the peeling tape 11 having a length twice that of the movement can be suitably synchronized. For this reason, in order to peel the workpiece | work 10 from the peeling tape 11 in the peeling part 21, the pressurization (tension | tensile_strength) which acts on the peeling tape 11 can be uniformly given over the whole peeling process. Therefore, the workpiece 10 can be peeled from the peeling tape 11 stably and preferably. Further, since the synchronization performance is high, the apparatus can be operated at a high speed. On the other hand, when a driving device that moves the reciprocating movable unit 20 and a driving device that feeds the peeling tape 11 are provided separately, it is difficult to increase the synchronization accuracy, and the driving device acts on the peeling tape 11. The pressure tends to fluctuate, making it difficult to perform a stable peeling operation.
Further, in this embodiment, since the mechanism is driven by one driving device, there is an advantage that the device can be simplified and made compact and the manufacturing cost can be reduced.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
