Firstly, placing a protective belt:

When the protective tape is unreeled, the protective tape is sleeved on the unreeling roller 11 in the form of a protective roll 14, the protective tape unreeled from the protective roll 14 under the traction of the traction pair roller 15 passes through the guide roller and the flattening plate 17 to reach the separation block 12 (before the protective tape and the basement membrane 18 are not separated, the basement membrane 18 is attached to the upper surface of the separation block 12, and the protective tape is positioned above the basement membrane 18), and then the basement membrane 18 of the protective tape is wound on the recovery roller 13; through recovery roll 13 to facilitate recovery of base film 18.

Second, the protective sheet is torn from carrier film 18:

After the protective sheet reaches the separation block 12, the traction roller pair 15 stops drawing the bottom film 18, the protective belt stops unreeling, the ball screw sliding table arranged on the frame 1 drives the adsorption part to move above the separation block 12 with the protective belt through the connecting seat 31, and then the ball screw sliding table stops; then, the first driver 41 of the lifting unit 4 is started, so that the lifting assembly 42 drives the adsorption plate 6 to move downwards, and when the adsorption plate 6 moves to be attached to the protection sheet, a vacuum pump is started (at this time, the first driver 41 is stopped), so that the adsorption hole 62 on the adsorption plate 6 generates negative pressure to adsorb the protection sheet; then, the ball screw sliding table is started again, so that the ball screw sliding table drives the adsorption part to move rightwards until the protection sheet is separated from the bottom film 18, and meanwhile, the bottom film 18 without the protection sheet is automatically rolled by the recovery roller 13.

Thirdly, conveying and sticking the protection sheet:

After the protection piece tears off, the ball screw slip table continues to start for connecting seat 31 drives the adsorption component and protects the piece and moves right together, after the top of soft board position on workstation 2 was reachd to the screening glass on adsorbing board 6, the ball screw slip table stopped, and start driver 41, make lifting unit 42 drive adsorption board 6 downstream, paste screening glass and soft board, and the vacuum pump is closed at last, and the screening glass forms the protection to the soft board promptly attached to on the soft board.

Before the protective sheet is pasted, when the protective sheet is unreeled, the protective sheet may be shifted forwards and backwards to be deflected, and the protective sheet is torn off by the adsorption plate 6; the rotation of the protection sheet in the horizontal plane can be achieved by the angle adjustment unit 5 to achieve the position correction of the protection sheet; the alignment of the positions of the protection sheet and the soft plate can also be realized by driving the workbench 2 to move through the axial adjusting unit 7; adjustment can also be achieved by the axial adjustment unit 7 in cooperation with the angle adjustment unit 5.

In addition, in the process that the protective sheet is torn off from the base film 18, as long as the protective tape is flattened when being initially adsorbed on the flattening plate 17, and the base film 18 of the protective tape is tightly adsorbed by the suction holes formed in the flattening plate 17, the protective tape cannot easily wrinkle in the process of continuously unreeling the protective tape, and meanwhile, the degree of deflection caused by the fact that the protective tape shifts forwards and backwards in the unreeling process can also be reduced.

Example two

The second embodiment is basically as shown in fig. 6 to 9, and is improved on the basis of the first embodiment, specifically: still be connected with the blowing pipe 19 through screw fixed connection on the frame 1, the blowing pipe 19 is located the separation block 12 below, and it has a plurality of trompil pore 191 up to open on the blowing pipe 19, and the blowing pipe 19 intercommunication has the air pump.

Provide wind-force for blowing pipe 19 through the air pump for wind energy on the blowing pipe 19 blows to being adsorbed the screening glass bottom by adsorption plate 6 along gas pocket 191, and then avoids the bottom that the dust fell the screening glass around, has guaranteed the clean and tidy of screening glass viscose position, and then solves screening glass viscose position and lead to pasting insecure problem with the soft board because of the adhesion dust.
