[0025] Embodiment 2

[0026] See also Figure 4-5 A ring plate 17 is fixedly installed on the surface of the rotating rod 6, and a telescopic rod 18 is fixedly installed on the top of the ring plate 17. A spring 19 is sleeved on the surface of the telescopic rod 18. One end of the spring 19 is fixedly installed on the top of the ring plate 17, and the other end of the spring 19 is fixedly installed on the bottom end of the pad 20. A pad 20 is fixedly installed on the top of the telescopic rod 18.

[0027] Working principle: When working, first rotate the screw rod 9 and drive the frame plate 10 to move up and down along the direction of the guide rod 12 under the action of the thread, and place the thin plate on the surface of the adsorption plate 16. Then start the motor 3 and drive the bidirectional threaded rod 4 to rotate. Under the action of the thread, the two groups of moving blocks 5 will move in the opposite direction along the slide groove 2, so as to drive the roller 7 to contact the thin plate. Then, with the movement of the moving block 5, the thin plate will gradually adjust its position under the action of the roller 7 and realize the centering work on the surface of the processing table 1. During this process, the pressure wheel 11 will press on the edge of the thin plate, so as to prevent the edge of the thin plate from warping due to excessive thrust of the moving block 5. Then start the exhaust fan 14 and extract the air inside the processing table 1 through the pipe 15 , so that the adsorption plate 16 generates attraction to the outside and adsorbs the thin plate to prevent the thin plate from deflecting. When maintenance work on the roller 7 is required, first press down the roller 7 and drive the pad 20 to descend along the rotating rod 6. When enough space is reserved for the limiting plate 21, the limiting plate 21 is rotated 90°, and then the roller 7 can be moved out from the surface of the rotating rod 6 from bottom to top. During installation, first insert the roller 7 along the rotating rod 6, then press down and drive the pad 20 to slide, so that the spring 19 and the telescopic rod 18 are deformed, and then the limiting plate 21 is rotated 90° again. At this time, under the action of the spring 19 and the telescopic rod 18, the pad 20 and the roller 7 will be driven to push against the limiting plate 21, and the installation of the roller 7 is completed.
