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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of an air conditioning control circuit board surface coating device, including a workbench 1, a coating rack 2 fixedly connected to the top left side of the workbench 1, the coating rack 2 is used to apply a protective layer to the circuit board, a servo motor 3 is fixedly connected to the top of the workbench 1, and a placement platform 4 is fixedly connected to the output end of the servo motor 3, the servo motor 3 drives the placement platform 4 to rotate on the top of the workbench 1, and a placement plate 5 is elastically connected inside the placement platform 4 through a return spring 6, the placement plate 5 is used to place the circuit board, and at the same time the placement plate 5 squeezes the return spring 6 to deform the return spring 6. When resetting, the rebound of the return spring 6 drives the placement plate 5 to slide and reset. Furthermore, the placement table 4 has a placement groove inside, and the placement plate 5 is connected to the placement groove by a sliding groove. The placement groove is used to place and store the placement plate 5. The inner side wall of the placement table 4 is provided with a clamping mechanism 7. The top right side of the workbench 1 is provided with a cleaning component 8. The bottom of the coating rack 2 is provided with a coating plate 9. The coating plate 9 slides on the top of the coating rack 2 to apply coating to the circuit board. The side wall of the workbench 1 is fixedly connected with a paint tank 10. The top of the paint tank 10 is provided with a feed port. The side wall of the paint tank 10 is connected to the coating plate 9 through a connecting pipe. The liquid inside the paint tank 10 is transported to the inside of the coating plate 9 by a water pump.

[0019] Reference Figures 2-3 The clamping mechanism 7 includes a clamping block 71, which is slidably connected to the inner wall of the placement platform 4. A connecting groove is provided on the side wall of the placement groove, and the clamping block 71 is slidably connected in the connecting groove. The clamping block 71 is slidably connected to the inside of the placement platform 4 by means of the connecting groove. The side wall of the placement plate 5 is in contact with the side wall of the clamping block 71. The clamping block 71 is used to squeeze and limit the side wall of the placement plate 5. The side wall of the clamping block 71 is elastically connected to the inner wall of the placement platform 4 by a positioning spring 72. When the clamping block 71 is pushed, it squeezes the positioning spring 72, causing the positioning spring 72 to deform. When resetting, the rebound of the positioning spring 72 drives the clamping block 71 to slide and reset. A telescopic rod 73 is fixedly connected to the side wall of the clamping block 71. The end of the telescopic rod 73 is fixedly connected to the inner wall of the placement platform 4. The telescopic rod 73 is used to limit the clamping block 71 and ensure that the clamping block 71 slides stably in the connecting groove.

[0020] Reference Figures 2-4 The cleaning component 8 includes a cleaning frame 81. The bottom of the cleaning frame 81 is fixedly connected to the top right side of the workbench 1. The bottom of the cleaning frame 81 contacts the top of the plate. A connecting frame 82 is fixedly connected to the bottom of the cleaning frame 81. A connecting block 84 is inserted into the inside of the connecting frame 82. A T-shaped groove adapted to the size of the connecting block 84 is opened inside the connecting frame 82. Through the setting of the T-shaped groove and the connecting block 84, a stable connection is made between the connecting block 84 and the connecting frame 82. A cleaning plate 83 is fixedly connected to the side wall of the connecting block 84. A cleaning sponge is set at the bottom of the cleaning plate 83. The cleaning sponge is used to clean the top of the circuit board, improving the cleanliness of the circuit board during the coating process.

[0021] Working principle: During use, the circuit board is placed on the placement plate 5. After pressing the placement plate 5, the return spring 6 is squeezed and the board slides inside the placement platform 4. During the sliding process, the placement plate 5 loses its pressure on the clamping block 71. At the same time, the positioning spring 72 resets and drives the clamping block 71 to slide and reset inside the placement platform 4, thus achieving a stable clamping effect on the side wall of the circuit board on the placement plate 5. At the same time, the telescopic rod 73 limits the clamping block 71, and the bottom of the clamping block 71 protects the top of the placement plate 5, improving the stability of the placement plate 5 and achieving a stable clamping effect on the circuit board on the top of the placement plate 5. The servo motor 3 drives the placement platform 4 to rotate. When the placement platform 4 rotates to the bottom of the cleaning rack 81, the cleaning plate 83 cleans the circuit board placed on the placement plate 5, improving the cleanliness of the circuit board during the coating process. Simultaneously, the rotation of the placement platform 4 drives the circuit board to rotate, moving it to the bottom of the coating rack 2. The movement of the coating plate 9 applies a protective coating to the top of the circuit board, improving the stability of the coating process. After the circuit board is coated, the servo motor 3 drives the placement platform 4 to rotate, moving the coated circuit board to the front of the worktable 1. Then, the clamping block 71 is pushed, squeezing the positioning spring 72 and the telescopic rod 73, causing the circuit board to slide inside the placement platform 4. At the same time, the placement plate 5 loses its limit. The return spring 6 causes the placement plate 5 to spring back and reset, sliding the circuit board out of the placement platform 4. This allows the coated circuit board to be taken out and dried, improving the efficiency of the circuit board coating process.
