[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 This utility model discloses a hot-pressing device for producing capacitive touchscreens, comprising a processing box 1 forming a basic frame. First electric slide rails 2 are fixedly connected to the left and right sides of the top of the processing box 1, and first sliding blocks 3 are slidably connected to the outer walls of the first electric slide rails 2. This structural design allows the first sliding blocks 3 to move left and right on the first electric slide rails 2, providing a basis for subsequent component position adjustments. A support column 4 is fixedly connected to the top of the first sliding block 3, extending upwards, and a horizontal plate 5 is fixedly connected to its top. The horizontal plate 5 serves to support and connect other components.

[0034] A second electric slide rail 6 is fixedly connected to the bottom of the horizontal plate 5, and a second sliding block 7 is fixedly connected to the bottom of the second electric slide rail 6. This structure allows the second sliding block 7 to slide back and forth on the second electric slide rail 6, further enriching the movement dimensions of the equipment. A cylinder 8 is fixedly connected to the bottom of the second sliding block 7. The cylinder 8 serves as a power output component and can achieve vertical extension and retraction.

[0035] An electric push rod 9 is fixedly connected to the inner wall of the left side of the processing box 1, and a push block 11 is fixedly connected to the output end of the electric push rod 9. A groove 12 is opened at the bottom of the push block 11, and a slider 13 is slidably connected to the inner wall of the groove 12. A sliding plate 14 is fixedly connected to the bottom of the slider 13, and a uniformly distributed spring 15 is fixedly connected to the bottom of the sliding plate 14. A cleaning pad 16 is fixedly connected to the bottom of the spring 15. This structural design allows the cleaning pad 16 to adapt to different surface conditions under the action of the spring 15, and the cleaning operation of the processing area can be realized through the coordinated movement of the electric push rod 9, the push block 11, the slider 13, and the sliding plate 14.

[0036] The machining box 1 contains a drive assembly. (Combined) Figure 2 and Figure 3 The drive assembly includes a support rod 25 fixedly connected to the inner wall of the processing box 1, and a fixed plate 10 fixedly connected to the top of the support rod 25. Limiting blocks 28 are fixedly connected to the top of both sides of the fixed plate 10, and a bidirectional motor 32 is fixedly connected to the middle of the top of the rear fixed plate 10. A lead screw 27 is fixedly connected to the output end of the bidirectional motor 32, and the lead screw 27 is rotatably connected to the limiting block 28. A clamping plate 29 is threaded to the outer ring of the lead screw 27. A guide post 30 is slidably connected through one end of the clamping plate 29, and the guide post 30 is fixedly connected to the limiting block 28. At the same time, a connecting plate 26 is fixedly connected between the fixed plates 10, and evenly distributed moving blocks 31 are slidably connected to the top of the connecting plate 26. The moving blocks 31 are fixedly connected to the clamping plates 29 on both sides respectively. When the bidirectional motor 32 is working, it drives the lead screw 27 to rotate. Since the clamping plate 29 is threadedly connected to the lead screw 27 and is restricted by the guide post 30, the clamping plate 29 will move along the axial direction of the lead screw 27, thereby realizing the clamping or releasing operation of the capacitive touch screen placed between the clamping plates 29. Furthermore, the sliding of the moving block 31 on the connecting plate 26 can ensure the stability of the movement of the clamping plate 29.

[0037] Reference Figure 3 and Figure 4A push plate 18 is fixedly connected to the output end of cylinder 8. A recessed box 17 is fixedly connected to the bottom of push plate 18. A sliding column 20 is slidably connected inside the recessed box 17. A sliding disk 19 is fixedly connected to the top of sliding column 20 and is slidably connected to the inner wall of recessed box 17. A damping spring 21 is sleeved on the outer ring of sliding column 20 and is fixedly connected to the bottom of recessed box 17. A first magnet 22 is fixedly connected to the bottom of damping spring 21, and a second magnet 23 is attracted to the bottom of the first magnet 22. A heating plate 24 is fixedly connected to the bottom of the second magnet 23. When cylinder 8 pushes push plate 18 downward, it causes recessed box 17, sliding column 20, and other components to descend together. During the descent of heating plate 24, damping spring 21 can buffer and adjust pressure, allowing heating plate 24 to contact the capacitive touch screen more stably. The attraction connection between the first magnet 22 and the second magnet 23 facilitates the installation and removal of heating plate 24.

[0038] Working Principle: When using this capacitive touchscreen production hot pressing equipment, the capacitive touchscreen to be processed is first placed between clamping plates 29. The bidirectional motor 32 is started, driving the lead screw 27 to rotate. The rotation of the lead screw 27 causes the clamping plates 29, which are threaded to it, to move along the axial direction of the lead screw 27. Under the guidance of the guide column 30, the two clamping plates 29 gradually move closer, clamping and fixing the capacitive touchscreen to ensure that the touchscreen will not shift during the hot pressing process. When cleaning of the processing area is required, the electric push rod 9 is started, pushing the push block 11 to move. The slider 13 in the bottom groove 12 of the push block 11 moves with the push block 11, thereby driving the sliding plate 14 to move. The spring 15 at the bottom of the sliding plate 14 will adaptively adjust according to the surface condition of the processing area, allowing the cleaning pad 16 to closely adhere to the surface of the processing area, cleaning the processing area, removing any impurities, and ensuring the hot pressing effect. After cleaning is completed, the cylinder 8 is started, and the output end of the cylinder 8 pushes the push plate 18 downwards, causing the groove box 17 to descend. The sliding column 20 inside the recessed box 17, under the action of the damping spring 21, slowly and steadily moves the heating plate 24 closer to the capacitive touchscreen. Once the heating plate 24 contacts the capacitive touchscreen, it heats it, while the cylinder 8 continues to provide pressure, achieving a hot-pressing operation on the capacitive touchscreen. During the hot-pressing process, the damping spring 21 acts as a buffer, preventing the heating plate 24 from applying excessive pressure to the capacitive touchscreen and causing damage. Furthermore, the attraction between the first magnet 22 and the second magnet 23 ensures the stable installation of the heating plate 24. After hot-pressing is complete, the cylinder 8 retracts, causing the heating plate 24 to rise and move away from the capacitive touchscreen. The bidirectional motor 32 is then restarted, causing the clamping plate 29 to move in the opposite direction, releasing the capacitive touchscreen, and allowing the processed product to be removed. Throughout the operation, the first electric slide rail 2 and the second electric slide rail 6 can adjust the positions of components such as the cylinder 8 and the heating plate 24 according to actual processing needs by controlling the movement of the first sliding block 3 and the second sliding block 7, adapting to capacitive touchscreen processing tasks with different sizes and positional requirements.
