And a table 52 having a surface 52A.

The operation of the sheet sticking device EA1 including the above unnecessary sheet removing device EA will be described.
First, the user of the sheet sticking apparatus EA1 (hereinafter, simply referred to as “user”) attaches the adhesive sheet laminate RS1 to the sheet sticking apparatus EA1 in which each member is arranged at an initial position indicated by a solid line in FIG. It is set as shown in the figure, and a signal for starting automatic operation is inputted through operation means (not shown) such as an operation panel and a personal computer. Then, the unnecessary sheet reinforcing means 20 drives the linear motor 21A, and pierces the second release sheet RL2 of the adhesive sheet laminate RS1 with the cutting blade 21C so as not to penetrate the adhesive sheet base material BS. After that, the feeding means 10, the unnecessary sheet reinforcing means 20, and the collecting means 30 drive the rotation motors 13A, 14D, 22A, 31A to feed the adhesive sheet laminate RS1, and rotate the die cut roller 13D to feed the adhesive sheet base material. By forming the cut-in sheet CU1 for forming the adhesive sheet in a closed loop shape on the BS, a material RS on which the adhesive sheet AS and the unnecessary sheet US are temporarily attached is formed on the first release sheet RL1, and the material RS is fed out. .

Next, as shown in FIG. 1, a camera, a projector, or the like notifies that the leading end of the leading adhesive sheet AS temporarily attached to the first release sheet RL1 in the feeding direction has reached a predetermined position below the third guide roller 12C. When an unillustrated sheet leading end detecting device including various sensors such as an optical sensor and an ultrasonic sensor detects an image pickup unit, the feeding unit 10, the unnecessary sheet reinforcing unit 20, and the collecting unit 30 rotate the rotating motors 13A, 14D, 22A. , 31A are stopped.
Here, when the raw material RS is fed out as described above, as shown in a diagram of a reference AA which is a CC arrow view of a BB-BB cross section in FIG. 1, the second release sheet RL2 is cut by a cutting blade 21C. Is divided into an inner removal sheet ES and an outer reinforcement sheet LS at the boundary of the reinforcing sheet forming cut CU2 formed by the above, and the removal sheet ES is separated from the adhesive sheet base material BS by the second guide roller 12B. The sheet is taken up and collected by the removal sheet collecting roller 22B.
On the other hand, the reinforcing sheet LS reinforces the unnecessary sheet US while being temporarily attached to the unnecessary sheet US, and the unnecessary sheet US reinforced by the reinforcing sheet LS is separated from the first release sheet RL1 by the fourth guide roller 12D. It is peeled off and wound around the unnecessary sheet collecting roller 31 to be collected.

  Thereafter, when a user or a transfer means (not shown) such as a belt conveyor or an articulated robot places the wafer WF on the holding surface 52A as shown in FIG. 1, the support means 50 drives the pressure reducing means (not shown). Then, the suction holding of the wafer WF on the holding surface 52A is started. Next, the linear motor 14A is driven in a state in which the feeding means 10 locks the driving of the rotation motor 14D, and as shown by a two-dot chain line in FIG. Roll out. Also in this case, the feeding means 10, the unnecessary sheet reinforcing means 20, and the collecting means 30 drive the rotating motors 13A, 22A, 31A, collect the removed sheet ES by the removed sheet collecting roller 22B, and adhere to the adhesive sheet base material BS. The sheet forming cut CU1 is formed to form the raw sheet RS, and the unnecessary sheet US reinforced by the reinforcing sheet LS is collected by the unnecessary sheet collecting roller 31. Then, when a sheet leading end detecting device (not shown) detects that the leading end of the next adhesive sheet AS following the leading adhesive sheet AS in the feeding direction has reached a predetermined position below the third guide roller 12C, the feeding means 10 becomes unnecessary. The sheet reinforcing means 20 and the collecting means 30 stop driving the linear motor 14A and the rotation motors 13A, 22A, 31A.

  Next, the support means 50 drives the linear motion motor 51, and as shown by the two-dot chain line in FIG. 1, after raising the table 52, the pressing means 40 drives the linear motor 14A and the rotation motor 14D, The support plate 14C is moved to the left while rolling the roller 14F to press the material RS against the wafer WF. Thereby, the adhesive sheet AS is stuck on the upper surface of the wafer WF, the first release sheet RL1 is peeled off from the adhesive sheet AS, and the peeled first release sheet RL1 is collected by the release sheet collecting roller 14G. Thereafter, when the first release sheet RL1 is completely peeled off from the adhesive sheet AS and the support plate 14C returns to the initial position, the pressing means 40 stops driving the linear motor 14A and the rotation motor 14D.

  Next, after the supporting means 50 drives the linear motor 51 to return the table 52 to the initial position, the driving of the pressure reducing means (not shown) is stopped, and the suction holding of the wafer WF on the holding surface 52A is released. Then, the user or a transfer unit (not shown) transfers the wafer WF on the holding surface 52A to the next step, and thereafter, the same operation as described above is repeated.

  According to the above-described embodiment, the unnecessary sheet US is reinforced and collected, so that the unnecessary sheet US peeled from the first release sheet RL1 is prevented from being cut by the tension of the collection unit 30 as much as possible. US collection failure can be prevented as much as possible.
