Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 , the embodiments provided by the present utility model:

[0024] It includes an operating table 1, on the surface of which a mounting bracket 2 is welded. At least four hydraulic cylinders 5 are sequentially assembled on the mounting bracket 2. The output ends of the hydraulic cylinders 5 are fixedly connected to a mounting plate 6. A pressing plate 8 is provided at the bottom of the mounting plate 6. Four pressure sensors 7 are sequentially and evenly assembled between the bottom surface of the mounting plate 6 and the surface of the pressing plate 8. The positions of the pressure sensors 7 correspond to the output ends of the hydraulic cylinders 5. By setting the pressure sensors 7, an auxiliary supervision effect can be achieved, and the pressure reading between the pressing plate 8 and the device to be film-coated can be displayed in real time during the operation of the hydraulic cylinder 5, so as to achieve a sufficient detection effect, avoid inconsistent pressure at each part, and ensure the pressing and film-coating effect.

[0025] A backing plate 4 is laid on the surface of the operating table 1. Buffer mechanisms 9 are symmetrically arranged on the surface of the backing plate 4. The operating table 1 is assembled with a fixing mechanism 10 on one side of the backing plate 4;

[0026] The buffer mechanism 9 includes a column 11, two pressing plates 15 and two connecting rods 17. The column 11 is fixed on the surface of the backing plate 4. An opening groove 14 is formed on the surface of the column 11. A guide rod 19 is installed in the opening groove 14 of the column 11. Two pressing plates 15 are slidably installed on the surface of the guide rod 19. Chute grooves 18 are formed on both of the two pressing plates 15. One side of each of the two connecting rods 17 is hinged to the two pressing plates 15 respectively. The other ends of the two connecting rods 17 are respectively hinged with sliders, and the sliders are slidably installed at the chute grooves 18 of the two pressing plates 15. Raised edges 12 are integrally formed at both ends of the column 11. The two raised edges 12 are respectively in contact with the surfaces of the pressing plate 8 and the mounting plate 6. The raised edges 12 are provided as a certain limiting structure to determine the highest position of the mounting plate 6 and the lowest position of the pressing plate 8, so as to avoid unnecessary damage. Guide edges 16 are integrally formed on both sides of the two pressing plates 15. The guide edges 16 are slidably installed on the inner wall of the opening groove 14. The guide edges 16 are provided to assist in the positional structural stability of the pressing plates 15, to avoid being easily damaged by external bumps, and at the same time, it can also have a certain auxiliary guiding effect. When being pressed, as the pressure is transmitted, the pressing plates 15 can move downward and affect each other, so that one end of each connecting rod 17 starts to move along the position of the chute groove 18, thereby playing an auxiliary buffering effect, and ensuring that the pressure action can be carried out gently and evenly, and ensuring the pressing effect.

[0027] The fixing mechanism 10 includes a fixing plate 21, mounting blocks 22, a cross bar 23 and clamping arms 24. The fixing plate 21 is welded to the surface of the operating table 1. The two sides of the fixing plate 21 are symmetrically welded with the mounting blocks 22. The cross bar 23 is installed between the respective mounting blocks 22. A mounting edge 25 is integrally formed on the surface of the clamping arm 24. The clamping arm 24 is slidably installed at the cross bar 23 through the cooperation of the mounting edge 25. A compression spring 26 is sleeved on the cross bar 23. One end of the compression spring 26 is in contact with the mounting edge 25. A damping rod 27 is inserted into the surface of the fixing plate 21. A cushion block 28 is laid at one end of the damping rod 27. Both the cushion block 28 and the backing plate 4 are integrally structured and made of rubber material. The other end of the damping rod 27 is fixedly connected to the mounting frame 2 through the cooperation of a connecting piece 29. The setting of the fixing mechanism 10 is used to play an auxiliary fixing effect. During the processing, the two clamping arms 24 can be manually opened at any time, so that the clamping arms 24 can be separated by a sufficient position. During this period, the mounting edges 25 on the clamping arms 24 translate along the cross bar 23 and deform the compression spring 26, thereby generating a sufficient and good auxiliary compressive effect. As the equipment is fed in, one end of the equipment contacts and presses against the cushion block 28, and pushes the damping rod 27 to contract. At this time, the two clamping arms 24 are released, and they are pushed and pressed by the force generated by the deformation of the compression spring 26, and thus the fixing effect on the equipment is completed, which is convenient for subsequent work.
