[0009] Preferably, the bottom end of the rotating rod is rotatably connected inside the limiting seat, and the two ends of the connecting rod are respectively fixedly connected to limiting sleeves, which are rotatably connected to the outside of the connecting frame plate.

[0013] (III) Beneficial Effects

[0014] This invention provides a vacuum coating device for the surface of a plastic backing plate. It has the following advantages:

[0015] (1) The plating tank serves as the main space for the coating process. The motor drives the rotating rod to rotate, and the bottom of the rotating rod is positioned by a limit seat to ensure stable rotation. The rotating rod drives the connecting rod to make a circular motion. The limit sleeve on the connecting rod ensures that its motion trajectory is accurate. The small gear at the bottom of the connecting rod meshes with the large gear and rotates around the rotating rod while rotating itself. This causes the plastic back plate to flip and move at multiple angles within the plating tank. This combination solves the problems of fixed position of the plastic back plate, incomplete coating coverage, and low efficiency in traditional coating devices. It avoids rework caused by uneven coating in some areas. Through the linkage of the large and small gears, the plastic back plate can achieve compound motion, so that the coating material can evenly cover each surface, significantly improving the comprehensiveness, uniformity, and efficiency of the coating, reducing manual intervention, and optimizing the coating process.

[0016] (2) The mounting block is fixedly connected, the fixing plate provides the support base, and the mounting plate has a sliding groove. The sliding block drives the clamping plate to move within the sliding groove. When the clamping plate is pushed outward, the spring is stretched and stores force. After the clamping plate is sufficiently spaced to place the plastic back plate, it is released. The spring rebound force drives the clamping plate to reset and clamp the back plate. This combination solves the problem of cumbersome workpiece installation and unstable fixation in traditional coating devices. It changes the inefficient operation mode of repeated manual adjustment. Through the linkage between the spring and the sliding groove, the plastic back plate can be quickly loaded and unloaded and stably fixed. It avoids uneven coating caused by workpiece shaking during the coating process, improves installation efficiency and fixation reliability, reduces the defect rate caused by clamping problems, and makes the coating operation more convenient and efficient.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A vacuum coating device for a plastic backing plate includes a coating tank 1. A motor 2 is fixedly connected to the top of the coating tank 1. A rotating rod 3 is fixedly connected to the output end of the motor 2. Connecting frame plates 23 are fixedly connected to the outer walls of both the upper and lower ends of the rotating rod 3. A limiting seat 4 is fixedly connected to the lower part of the interior of the coating tank 1. A large gear 5 is fixedly connected to the outer wall of the limiting seat 4. Multiple connecting rods 6 are rotatably connected between the two connecting frame plates 23. A small gear 8 is fixedly connected to the bottom end of each connecting rod 6, and the small gear 8 meshes with the large gear 5. At the same time, multiple plastic backing plates 9 are provided on the outside of the connecting rod 6. The bottom end of the rotating rod 3 is rotatably connected to the inside of the limiting seat 4. Limiting sleeves 7 are fixedly connected to both ends of the connecting rod 6, and the limiting sleeves 7 are rotatably connected to the outside of the connecting frame plates 23.

[0025] After the motor 2 is started, the rotating rod 3 begins to rotate, and its bottom end is firmly limited within the limit seat 4 to ensure stable rotation. The rotation of the rotating rod drives the connecting rod 6 on the connecting frame plate 23 to move together, so that the connecting rod rotates around the rotating rod. During this process, the small gear 8 at the bottom of the connecting rod rolls along the large gear 5, not only revolving but also rotating on its own axis. This compound motion allows the plastic back plate 9 fixed on the connecting rod to receive coating from multiple angles and all directions in the coating box 1, avoiding coating blind spots and greatly improving coating efficiency and uniformity.

[0026] Example 2: The difference between this example and Example 1 is that each connecting rod 6 has a mounting block 11 on its outer side wall. A fixing plate 12 is fixedly connected to the outer side wall of the mounting block 11. A pair of mounting plates 13 are fixedly connected to one side of the outer wall of the fixing plate 12. Springs 14 are fixedly connected to both sides of the mounting plate 13, and a sliding block 15 is fixedly connected to the other end of the spring 14. A clamping plate 16 is fixedly connected to the outer side wall of the sliding block 15, and a plastic back plate 9 is disposed between the two clamping plates 16. The mounting block 11 is fixedly installed inside the connecting rod 6 by a pin 10. The fixing plate 12 is located inside... The plate 1 has a pair of sliding grooves 17, and the sliding block 15 is slidably connected in the sliding grooves 17. At the same time, the inner side wall of the clamping plate 16 is provided with anti-slip texture. The plate 1 is rotatably connected to a door 18 on one side. The top of the plate 1 is fixedly connected to a vacuum tube 19. The plastic back plate 9 is rotatably connected to the inside of the plate 1. The inner side wall of the door 18 is fixedly connected to a temperature sensor 21. The upper part of the inside of the plate 1 is fixedly connected to a pressure sensor 22. The plate 1 is provided with a controller 20 on one side. The signal output terminals of the temperature sensor 21 and the pressure sensor 22 are connected to the signal input terminal of the controller 20.

[0027] When coating is required on the plastic back panel 9, first open the box door 18, and securely install the connecting rod 6 on the external fixing plate 12. Then push the clamping plates 16 to both sides. The clamping plates slide in the sliding groove 17 with the help of the sliding block 15, while stretching the spring 14. After the distance between the two clamping plates is sufficient to accommodate the plastic back panel, release the clamping plates. The spring will use its rebound force to drive the clamping plates to return to their original position, firmly limiting and fixing the plastic back panel. After installation, close the box door, use the vacuum tube 19 to evacuate the air from the box, and the temperature sensor 21 and pressure sensor 22 will transmit the internal temperature and pressure data to the controller 20 in real time, which will facilitate precise control by the staff. The coordinated operation of all components will enable the rapid loading and unloading of the plastic back panel, significantly improving work efficiency.

[0028] Working principle: When coating the plastic back panel 9 is required, first open the cabinet door 18 and fix the connecting rod 6 to the fixing plate 12 outside the connecting rod 6. Then, push the clamping plates 16 back to both sides. The clamping plates 16 move within the sliding groove 17 through the sliding block 15, which will pull the spring 14. When the distance between the two clamping plates 16 is sufficient to place the plastic back panel 9, the clamping plates 16 can be released. The spring 14 will drive the clamping plates 16 to return to their original position through its elasticity and limit and fix the plastic back panel 9. After installation, close the cabinet door 18 and evacuate the internal air through the vacuum tube 19. The internal temperature sensor 21 and pressure sensor 22 will monitor the temperature. The temperature and pressure are transmitted to the controller 20, which facilitates operation by the staff. Through their cooperation, the plastic back plate 9 can be quickly installed and removed, improving work efficiency. After completion, the starting motor 2 drives the rotating rod 3 to rotate. The bottom end of the rotating rod 3 is limited in the limit seat 4. When the rotating rod 3 rotates, it will drive the connecting rod 6 on the connecting frame plate 23 to rotate. The connecting rod 6 makes a circular motion and rotates around the rotating rod 3. At this time, the small gear 8 at the bottom of the connecting rod 6 will rotate with the large gear 5 and rotate on its own axis, so that the plastic back plate 9 can be coated more comprehensively in the plating box 1, improving the coating efficiency.

[0029] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
