Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Refer to Figures 1-4 , a fixture for coating a mobile phone screen in production, including a table body 1. A placement groove 2 is opened on the top surface of the table body 1. A placement plate 3 is arranged inside the placement groove 2. Two clamping blocks 4 are arranged on the top surface of the placement plate 3. A first sliding groove 5 is opened on the top surface of the clamping block 4. A pressing hole 6 is opened on the inner bottom surface of the first sliding groove 5. Two second sliding grooves 7 are opened on one side inside the first sliding groove 5. A pressing plate 8 is arranged inside the first sliding groove 5. Through the design of the clamping block 4 and the pressing plate 8, the clamping block 4 can be moved to clamp the mobile phone screen. After clamping, the two ends are pressed by the pressing plate 8 to ensure that it is horizontal and has better stability. Two first sliding blocks 9 are fixedly installed on one side of the pressing plate 8. The pressing plate 8 is sleeved inside the first sliding groove 5 through the first sliding blocks 9 and the second sliding grooves 7. An air cushion 10 is fixedly installed on the bottom surface of the pressing plate 8. At the same time, through the design of the air cushion 10, the two ends of the mobile phone screen can be protected to avoid unnecessary losses caused by excessive force during pressing;
[0023] Two clamping blocks 12 are fixedly installed on the bottom surface of the pressing plate 8. Two clamping grooves 11 are opened on the inner bottom surface of the first sliding groove 5. Through the design of the clamping blocks 12 and the clamping grooves 11, after pressing the mobile phone screen, the pressing plate 8 can be clamped in a fixed position, so that after the external force is removed, it still fixes the position to press and position the screen. A plurality of sliding holes 13 are opened on the top surface of the placement plate 3. Two sliding holes 13 in the horizontal direction are in a group. Two second sliding blocks 14 are fixedly installed on the bottom surface of the clamping block 4. Through the design of the sliding holes 13 and the second sliding blocks 14, the position of the clamping block 4 can be moved so that the device can effectively clamp screens of different sizes, making the device have better flexibility. The clamping block 4 is sleeved on the top surface of the placement plate 3 through the sliding holes 13 and the second sliding blocks 14. A second spring 18 is fixedly installed inside the sliding holes 13. A through hole is opened on one side of the table body 1. Rotating shafts 15 are fixedly installed on both sides of the placement plate 3. Nuts 16 are threadedly connected to the outer wall surfaces of the rotating shafts 15. The placement plate 3 is sleeved inside the placement groove 2 through the rotating shafts 15. Through the design of the rotating shafts 15 and the nuts 16, it can be ensured that the placement plate 3 can be rotated and finely adjusted, so that when coating and applying cleaning liquid, the placement plate 3 can be rotated to make the liquid move on the surface to ensure its uniform coating on the surface. At the same time, through the nuts 16, after uniform coating, the placement plate 3 can be fixed by tightening, which is convenient for the next operation. The rotating shaft 15 is composed of a smooth cylindrical part, a cylindrical part with a threaded outer wall surface, and a disc part at one end. Through the design of the rotating shaft 15, on the premise of ensuring the rotation of the placement plate 3, the thread on it can also cooperate with the nut 16 to fix the position of the placement plate 3 after the coating is completed. A first spring 17 is fixedly installed inside the second sliding groove 7. By setting the first spring 17, the position of the pressing plate 8 can be restricted. After disengaging the clamping, the pressing plate 8 is forced back to its original position by the elastic force of the first spring 17, which is convenient for the next fixing operation. Two drainage grooves 19 are opened on the top surface of the placement plate 3. Absorbent pads 20 are fixedly installed inside the drainage grooves 19. Through the design of the drainage grooves 19 and the absorbent pads 20, when coating and spraying cleaning liquid, the excess liquid can be diverted, and then adsorbed by the absorbent pads 20 to avoid liquid accumulation causing damage to the mobile phone screen.
[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
