The rotational load control unit 32 is configured by, for example, a reversing motor. When the tape load 5 is pulled out from the roll tapes 2A and 2B, the rotation load control means 32 controls the current to rotate in the direction opposite to the direction in which the shaft 11 rotates to adjust the load applied to the shaft 11. it can.

  Next, an operation example of the tape sticking apparatus 1 will be described. First, the adherend W is placed on the holding surface 23 of the holding table 22, and the ring-shaped frame F is placed on the frame support 24. The adherend W is an example of a workpiece such as a plate-like workpiece, and the material or the like is not particularly limited. A suction source (not shown) is operated, and the plate-like workpiece W is sucked and held by the holding surface 23 of the holding table 22.

  As shown in FIG. 3, for example, an operator pulls out the tape set 5 from the roll tape 2A and passes it through the guide 21a. Subsequently, the tape set 5 protruding downward from the guide 21 a is clamped by the first clamping means 12. Specifically, for example, the rotation mechanism 13 rotates in the direction of the arrow A1, positions the clamping member 121 of the first clamping unit 12 at the clamping position 6a, and clamps both ends of the end of the tape set 5 with the clamping member 121. To do.

  Next, the holding member 121 holding the tape set 5 is moved from the holding position 6a to the tape opening position 7 shown in FIG. Here, in the first roller unit 15 shown in FIG. 3, the moving means 152 moves the driven roller 151 away from the driving roller 150 (−X direction) before moving at least the clamping member 121 to the tape release position 7. The first tape set passage area 8 is formed between the drive roller 150 and the driven roller 151 so that the tape set 5 can pass therethrough.

  As shown in FIG. 4, when the clamping member 121 of the first clamping unit 12 is moved to the tape release position 7, the rotation mechanism 13 rotates in the direction of the arrow A <b> 2, for example, so that the first clamping unit 12 The tape set 5 sandwiched by the sandwiching member 121 is allowed to pass through the first tape set passage area 8, and the tape set 5 is hooked on the drive roller 150 to release the sandwiching member 121 sandwiching the tape set 5 from the tape. Move to position 7.

  Thereafter, as shown in FIG. 5, when the moving means 152 is operated, the moving portion 152b moves along the guide rail 152a, for example, in the direction of the arrow -X, causing the two driven rollers 151 to approach the driving roller 150, The two driven rollers 151 are brought into contact with the tape set 5 and the tape set 5 is sandwiched between the driving roller 150 and the two driven rollers 151. Then, the drive roller 150 rotates at a predetermined rotation speed, and the two driven rollers 151 also rotate with the rotation of the drive roller 150 to feed the tape set 5 downward.

  The moving unit 171 of the pulling mechanism 17 moves in the base 171 in the direction of the arrow + X, for example, and moves the second clamping unit 16 to the tape release position 7. When the first clamping unit 12 opens the tape set 5 at the tape release position 7, the support member 161 of the second clamping unit 16 takes over and holds both ends of the tape set 5. During this time, the second roller set 18 moves the driven roller 181 in the direction away from the driving roller 180 (−Z direction) by the moving means 182, and a predetermined second between the driving roller 180 and the driven roller 181. The tape set passage area 9 is formed. The second tape set passage area 9 is formed at least before the second clamping unit 16 clamps the tape set 5.

  As shown in FIG. 6, the tape set that is clamped by the clamping member 161 of the second clamping unit 16 by moving the moving unit 171 along the base 170 in a straight line, for example, in the direction of the arrow −X, by the drawer mechanism 17. 5 passes through the second tape set passage area 9.

  Next, as shown in FIG. 7, when the moving means 182 is operated, the moving portion 182b moves along the guide rail 182a, for example, in the arrow + Z direction, causing the two driven rollers 181 to approach the driving roller 180, and 2 One driven roller 181 is brought into contact with the tape set 5, and the tape set 5 is sandwiched between the driving roller 180 and the two driven rollers 181. The drive roller 180 rotates at a predetermined rotational speed, and the two driven rollers 181 rotate as the drive roller 180 is driven to feed the tape set 5 in the X-axis direction and from the roll tape 2A to the tape set 5 Pull out downward.

  Here, when the tape set 5 is pulled out from the roll tape 2 </ b> A, the rotational load applied to the shaft 11 is controlled by the rotational load control unit 32. That is, the tape set 5 is rewound by rotating the shaft 11 in the direction opposite to the drawing direction of the roll tape 2A attached to the shaft 11. Thereby, it is possible to prevent the tape set 5 drawn from the roll tape 2A and sandwiched between the first roller unit 15 and the second roller unit 18 from being slackened.

  The peel plate 19 shown in FIG. 7 lowers the arm portion 190 to press the protective film 4 of the tape set 5 downward with the pressing portion 191 to form the protective film 4 at an acute angle. If it does so, the tape 3a will peel from the protective film 4, and the tape 3a will be sent below the sticking roller 20. FIG. At this time, the holding table 22 that holds the adherend W and the frame support 24 that supports the frame F are moved in advance to the lower side of the tape set 5. For example, the protective film 4 from which the tape 3a has been peeled may be wound around a reel (not shown) and reused. Further, for example, a protective box 4 may be recovered by installing a recovery box below the second roller unit 18.

  The tape 3a is pressed from one side of the frame F supported by the frame support 24 by, for example, dropping in the direction of the arrow -Z while rotating the sticking roller 20 at a predetermined rotational speed. Subsequently, the holding table 22 and the frame support 24 are sent out in the direction of the arrow + X by the table moving means 26, and the tape 3a is pressed against the adherend W and the frame F by the rotating sticking roller 20. The electropneumatic regulator 34 adjusts the pressure when the tape 3 a is pressed by the sticking roller 20 by adjusting the pressure of air from the air supply source 33. In addition, in order to make the speed at which the tape 3a is stuck to the adherend W and the frame F and the speed at which the second roller unit 18 pulls out the tape set 5, the sticking roller 20 and the driving roller 180 are the same. It is desirable to rotate at a rotational speed. Note that the sticking roller 20 may be configured to rotate following the feed of the holding table 22 in the X-axis direction. In that case, the feeding speed of the holding table 22 and the rotation speed of the driving roller 180 are linked, and the sticking roller 20 can press the tape 3a fed according to the moving speed of the holding table 22.

  As shown in FIG. 8, when the holding table 22 and the frame support portion 24 are moved to predetermined positions while pressing the tape 3 a with the sticking roller 20, the tape 3 a is stuck to the adherend W and the frame F. be able to. Thereafter, the adherend W integrated with the frame F via the tape 3a is transferred to, for example, a dicing apparatus or the like by a conveying means (not shown), and dicing or the like is performed. When the sticking operation of the tape 3a to one piece of the adherend W is completed in this way, the new adherend W is sequentially transferred to the holding table 22 and the sticking operation of the tape 3a is repeatedly performed in the same manner as described above. .

  Here, by continuously pulling out the tape set 5 from the roll tape 2A, the tape set 5 of the roll tape 2A attached to the shaft 11 is reduced as shown in FIG. When the tape remaining amount recognizing unit 30 detects the shaft 11 on which the roll tape 2A is mounted, the tape remaining amount remaining information is sent to the control unit 31.

  When the control unit 31 determines that the tape set 5 of the roll tape 2A has completely disappeared based on the information of the tape remaining amount recognition unit 30, the control unit 31 stops the operation of pulling out the tape set 5 from the roll tape 2A, and the tape set 5 Is selected so that the tape set 5 is clamped and pulled out from the roll tape 2B with respect to the first clamping unit 12, the rotation mechanism 13, and the slide mechanism 14. Note that it is desirable to replace the used roll tape 2A with a new roll tape while the roll tape 2B is being used.

  As shown in FIG. 9, when the tape set 5 is pulled out from the roll tape 2 </ b> B by, for example, an operator and passed through the guide 21 b, the tape set 5 protruding downward from the guide 21 b is clamped by the first clamping means 12. Specifically, the first holding unit 12 is slid and moved to the roll tape 2B side by the slide mechanism 14. Next, the rotation mechanism 13 rotates, for example, in the direction of the arrow A1, positions the clamping member 121 of the first clamping unit 12 at the clamping position 6b, and clamps both ends of the end of the tape set 5 with the clamping member 121.

  As shown in FIG. 10, the holding member 121 holding the tape set 5 is moved from the holding position 6 b to the tape release position 7. Specifically, the first holding unit 12 holding the tape set 5 by the slide mechanism 14 is slid in, for example, an arrow + X direction. Subsequently, when the rotation mechanism 13 rotates, for example, in the direction of the arrow A2, the tape set 5 held by the holding member 121 of the first holding unit 12 passes through the first tape set passage area 8 and the tape. The set 5 is hooked on the drive roller 150, and the holding member 121 holding the tape set 5 is moved to the tape release position 7. Thereafter, the same operation as described above with reference to FIGS. 5 to 8 is performed, and the tape 3a is adhered to the adherend W.

  In the tape sticking apparatus 1 shown in the embodiment, instead of the rotational load control unit 32 configured by a reversing motor, for example, the rotational load applied to the shaft 11 is controlled using the rotational load control unit 40 shown in FIG. Also good. The rotational load control unit 40 includes an air supply source 41, an electropneumatic regulator 42 that adjusts the air pressure, and an air brake unit 43 that brakes the shaft 11. The rotational load control unit 40 can control the rotational load applied to the shaft 11 while braking the rotating shaft 11 using the air brake unit 43.

As described above, in the tape adhering device 1 of the present invention, the tape passing means 10 including at least two shafts 11 is provided, and the roll tapes 2A and 2B can be attached to the respective shafts 11. Since the tape set 5 of the roll tape 2B mounted on the other shaft 11 can be pulled out and used even if all the tape set 5 of the mounted roll tape 2A is pulled out and used up, the tape can be affixed to replace the roll tape. There is no need to stop the landing apparatus 1.
The tape passing means 10 selects either one of the roll tapes 2A and 2B and sandwiches the tape set 5 and the first sandwiching part 12 sandwiches the tape set 5 sandwiched by the first sandwiching part 12 The roller unit 15 and the clamping member 121 of the first clamping unit 12 selectively pulls out the roll tapes 2A and 2B while sandwiching the end sides of the tape set 5, so that one of the roll tapes 2A and 2B When the other roll tape 2A, 2B is used, the end of the old tape set 5 is aligned with the end of the new tape set 5 and the ends of both are overlapped. Therefore, the tape set 5 newly drawn from the other roll tapes 2A and 2B can be easily passed through the first roller unit 15.

In the tape sticking apparatus 1, the tape remaining amount recognition unit 30 recognizes the remaining amount of the roll tapes 2A and 2B, and the control unit 31 selects one of the usable roll tapes 2A and 2B based on the recognition. Even if one of the roll tapes 2A and 2B is used up, the tape 3a can be continuously adhered to the adherend W using the usable roll tape 2A or 2B.
Moreover, since either one of the roll tapes 2A and 2B is selectively used during operation of the tape applicator 1, a new roll tape is applied to the tape without stopping the tape applicator 1. The device 1 can be refilled.
