[0024] The upper end surface of the scraper 10 is fixedly mounted with a guide rod 26 located on the front and rear sides of the threaded rod 9. The movement of the guide rod 26 in the horizontal plate 25 limits the moving position of the scraper 10. The outer wall of the guide rod 26 is movably sleeved with the horizontal plate 25 located on the left side of the sleeve rod 7, and the inner wall of the horizontal plate 25 is threadedly sleeved with the outer wall of the threaded rod 9. The threaded sleeve connection method allows the threaded rod 9 to rotate in a circular direction while also realizing its vertical lifting movement, thereby providing power for the vertical movement of the scraper 10. The upper end of the guide rod 26 is fixedly mounted with a limit plate 27 located above the horizontal plate 25.

[0025] When the connecting rod 231 is pulled out from the outer rod body 22 and the inner rod body 24, the spring 232 is in a stretched state.

[0026] Working principle: When in use, first, place the rigid substrate body 1 and the flexible substrate body 2 to be peeled on the workbench 20, adjust the use height of the roller 3 according to the actual processing conditions, turn on the power of the drive motor 21, and after the drive motor 21 is turned on, it drives the rotation of the ball screw 802. Due to the threaded connection between the ball screw 802 and the ball nut 801, the ball screw 802 can rotate in a circular direction while also realizing the vertical lifting movement of the ball nut 801. When the ball nut 801 moves toward the roller 3, the ball nut 801 is connected to the inner wall of the extension rod 6 through the short rod 803. When the ball nut 801 moves, it drives the extension rod 6 to extend downward from the inside of the sleeve rod 7. At this time, the movement of the sleeve rod 7 drives the slider 28 to slide on the inner wall of the sleeve rod 7 through the connection of the annular block 29, thereby reinforcing the stability of the extension rod 6 in the telescopic movement of the sleeve rod 7. The movement of the extension rod 6 drives the roller 3 to move in the same direction until the outer wall of the roller 3 contacts the upper end surface of the flexible substrate body 2. Then, when it is necessary to adjust the horizontal position of the scraper 10, the outer rod body 22 and the inner rod body 24 are separated after pulling the connecting rod 231 through the setting of the pull ring 233. At this time, the movement of the connecting rod 231 stretches the spring 232 The inner rod 24 moves in the outer rod 22, and then uses the rebound of the spring 232 to insert the connecting rod 231 from the top of the outer rod 22 into the inside of the inner rod 24 and then extend it to the bottom of the outer rod 22. At this time, the connecting assembly 23 plays the role of connecting and limiting the outer rod 22 and the inner rod 24, so that the horizontal use position of the scraper 10 can be adjusted. Subsequently, when the vertical use position of the scraper 10 needs to be adjusted, due to the threaded connection between the threaded rod 9 and the cross plate 25, the threaded rod 9 rotates in a circular motion while driving its vertical lifting movement, and the threaded rod 9 moves while driving the scraper 10 vertically. The height of the scraper 10 is adjusted in the vertical direction. At this time, the rigid substrate body 1 and the flexible substrate body 2 are peeled off. Finally, the power of the vacuum pump body 4 is turned on. After the vacuum pump body 4 is turned on, the peeled flexible substrate body 2 is connected through the air inlet pipe 32, the air suction cover 30 and the interior of the through hole 11, so that the flexible substrate body 2 can be adsorbed on the surface of the roller 3. The peeled flexible substrate body 2 can be adsorbed on the surface of the roller 3. The power of the rotating motor 5 is turned on. After the rotating motor 5 is turned on, the rotating shaft 13 and the support frame 12 are connected to make the roller 3 rotate while driving the flexible substrate body 2 to be rolled up.
