The specific implementation process is as follows:
in this embodiment, and referring to fig. 2, protective sheets are first adhered to a continuous carrier film 18 at intervals to form a protective tape, and since the protective sheets and the carrier film 18 are both made of soft materials, the protective tape can be wound up into a protective roll 14.
The automatic protection film sticking machine film tearing control system of the embodiment I is used for tearing off the protection film on the protection belt from the bottom film 18, driving the protection film to move to the upper part of the soft plate, finally placing the protection film on the soft plate on the workbench 21, and finally sticking the protection film on the soft plate through the viscose carried by the protection film, so as to form protection on the soft plate, and comprises the following steps:
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, after the optical fiber sensor senses the protective sheet on the separation block 12, the P L C controller controls the traction roller 15 to stop traction on the basement membrane 18, the protective belt stops unreeling, the ball screw sliding table 3 installed on the machine frame 1 drives the adsorption part to move to the position above the separation block 12 with the protective belt through the connecting seat 31, then the ball screw sliding table 3 is stopped, the driver I41 of the lifting unit 4 is started, the lifting assembly 42 drives the adsorption plate 6 to move downwards, when the adsorption plate 6 moves to be attached to the protective sheet, the vacuum pump is started (the driver I41 is stopped), the vacuum pump enables the adsorption hole 62 on the adsorption plate 6 to generate negative pressure for adsorption, then the ball screw sliding table 3 is started again, the ball screw sliding table 3 drives the adsorption part to move rightwards until the protective sheet is separated from the basement membrane 18.
Thirdly, correcting the protecting sheet:
after the second step is completed, when the protective tape is unreeled, the protective tape may be shifted forwards and backwards to be deflected, and then the protective sheet is torn off by the adsorption plate 6, the camera 16 of the deviation correction unit collects image data at the protective sheet on the adsorption plate 6, the image data is transmitted to the image processing module, the image processing module calculates the actual position of the protective sheet on the adsorption plate 6 according to the image data, the image processing module compares the actual position of the protective sheet with a preset target position to obtain the angle offset of the protective sheet, the image processing module calculates the angle rotation amount and the position offset of the protective sheet based on the angle offset, and the P L C controller controls the second driver 51 of the angle adjustment unit 5 to drive the adsorption plate 6 to rotate on the horizontal plane to compensate the angle deviation generated by the protective sheet based on the angle rotation amount.
After the compensation of the angular deviation is completed, the camera 16 collects image data of the protective sheet on the adsorption plate 6 again, the image processing module calculates an actual position of the protective sheet on the adsorption plate 6 according to the image data, the image processing module compares the actual position of the protective sheet with a preset target position to obtain a position offset of the protective sheet (only the position offset remains because the angular deviation is completed), the image processing module calculates a position movement amount based on the position offset, the P L C controller controls the axial adjusting unit 7 to drive the workbench 21 to move back and forth (i.e. to move along the X axis) and controls the ball screw sliding table 3 to drive the adsorption part to move left and right (i.e. to move along the Y axis) based on the position movement amount to compensate the position deviation of the protective sheet generated on the X axis and the Y axis.
After the angle deviation and the position deviation are compensated, the automatic deviation rectifying function of the protection sheet is completely realized.
Fourthly, conveying and sticking the protecting sheet:
after accomplishing the third step, ball screw slip table 3 continues to start for connecting seat 31 drives the adsorption component and protects the piece and moves right together, and after the top of soft board position on workstation 21 was reachd to the protection piece on adsorbing board 6, ball screw slip table 3 stopped, and start driver 41, make lifting unit 42 drive adsorbing board 6 and move down, paste protection piece and soft board, and the vacuum pump is closed at last, and the protection piece forms the protection to the soft board promptly attached to the soft board.
After the screening glass is pasted with the soft board, start three 81 of driver, make three 81 of driver drive compression roller 82 downstream to support the soft board of tight area screening glass, stop three 81 of driver, and start ball screw slip table 3, drive reciprocating motion about compression roller 82 through ball screw slip table 3, make compression roller 82 round trip movement on the screening glass, and then hug closely the screening glass on the soft board through the roll-in of compression roller 82, the manual work has been solved and has been pasted tight screening glass and the insecure problem of pasting that the soft board exists.
In the embodiment, the protective sheet is torn from the bottom film 18 to be adhered to the soft board, the protective sheet does not need to be touched manually in the whole process, and the whole process is realized in a mechanized mode, so that the adhering efficiency of the protective sheet is higher; and the protective sheet is torn off from the bottom film 18 by the simultaneous action of the adsorption hole 62 on the adsorbed plate 6, the separation block 12 and the ball screw sliding table 3, and the corners of each protective sheet do not need to be manually uncovered and tilted, so that the situation that the protective sheet is torn off can be avoided.
In addition, in the process of tearing the protective sheet from the bottom film 18, as long as the protective tape is initially attached to the flattening plate 17 and is flattened, and the protective tape is tightly attached through the tightening holes formed in the flattening plate 17, the protective tape cannot be easily wrinkled in the process of continuously unwinding the protective tape, and the degree of deflection caused by forward and backward displacement of the protective tape in the unwinding process can be reduced.
Fifthly, taking down the soft board which finishes sticking the protection sheet from the workbench:
