When the coating is completed, the coolant is injected into the cooling chamber 501 through the liquid inlet pipe 502, and then the cooling nozzle 504 on the cooling chamber 501 can spray the coolant on the coated parts inside the vacuum coating chamber 1 to cool the coated parts, wherein the flow valve 503 can adjust the amount of coolant entering the cooling chamber 501 according to the temperature inside the vacuum coating chamber 1, and then the micro nozzle 505 in the cooling nozzle 504 can spray fine coolant droplets, which can more effectively reduce the temperature of the coating surface, and the droplets can evaporate quickly, take away more heat, and improve the heat dissipation efficiency, and then the column 401 can support the sliding frame 402, and then the coated parts are placed on the storage plate 408 and fixed by the clamping assembly 409.

At the same time, the cooperation of the I-shaped limit plate 403 and the limit block 407 can limit the movement of the storage plate 408, so that the movement of the storage plate 408 is more stable. When encountering a long coated part, the storage plate 408 drives the coated part to reciprocate under the cooling nozzle 504, so that the surface of the coated part can be evenly cooled, thereby improving the cooling quality of the coated part.

[0039] Specifically, Figure 1 As shown, a supporting column 16 is disposed at the bottom of the vacuum coating chamber 1 . The supporting columns 16 are in a plurality and are evenly disposed. A rubber pad 17 is disposed on the lower surface of the supporting column 16 .

[0040] When in use, first, the temperature sensor 11 can monitor the temperature inside the vacuum coating chamber 1. Since there are multiple temperature sensors 11 and they are evenly arranged inside the vacuum coating chamber 1, the temperature inside the vacuum coating chamber 1 can be better monitored. Then, the temperature can be transmitted to the display 13, so that the staff can understand the temperature inside the vacuum coating chamber 1. Then, the controller 12 can control the motor 405, the circulating water pump 10 and the temperature sensor 11. Then, the observation window 14 can facilitate the staff to observe the cooling condition of the coated parts inside the vacuum coating chamber 1, and then facilitate the staff to control the motor 405 to drive the storage plate 408 to move. Then, the tilting block 15 can guide the coolant entering the collection box 7, so that the coolant can smoothly enter the circulating water pipe 9. Then, the support column 16 can provide support for the vacuum coating chamber 1, and the rubber pad 17 can increase the friction between the vacuum coating chamber 1 and the ground, thereby further improving the stability of the vacuum coating chamber 1.

[0041] Working principle: When the present application is in use, the vacuum coating chamber 1 is first sealed through the sealing door 3, and then the interior of the vacuum coating chamber 1 is turned into a vacuum environment through the vacuum pump 2, and then the coating process can be carried out. When the coating is completed, the coolant is injected into the cooling chamber 501 through the liquid inlet pipe 502, and then the cooling nozzle 504 on the cooling chamber 501 can spray the coolant on the coated parts inside the vacuum coating chamber 1 to cool the coated parts, wherein the flow valve 503 can adjust the amount of coolant entering the cooling chamber 501 according to the temperature inside the vacuum coating chamber 1, and then the micro nozzle 505 in the cooling nozzle 504 can spray fine coolant droplets, which can more effectively reduce the temperature of the coating surface, and the droplets can The coating piece is then placed on the storage plate 408 and fixed by a clamping assembly 409. The clamping assembly 409 is a commonly used prior art and will not be described in detail. The motor 405 is then used to drive the bidirectional screw rod 404 to rotate. Since the sliding block 406 is threadedly connected to the bidirectional screw rod 404, when the bidirectional screw rod 404 rotates, the storage plate 408 can be driven to move on the sliding frame 402. At the same time, the coordinated use of the I-shaped limit plate 403 and the limit block 407 can limit the movement of the storage plate 408, making the movement of the storage plate 408 more stable. When encountering a longer coating piece, the storage plate 408 can be placed on the storage plate 408. The plate 408 drives the coated part to move back and forth under the cooling nozzle 504, so that the surface of the coated part can be evenly cooled, thereby improving the cooling quality of the coated part.

The handle 18 can provide a fulcrum for the staff to open and close the sealed door 3, and then the temperature sensor 11 can monitor the temperature inside the vacuum coating chamber 1. Since there are multiple temperature sensors 11, which are evenly arranged inside the vacuum coating chamber 1, the temperature inside the vacuum coating chamber 1 can be better monitored. , and then the temperature can be transmitted to the display 13, so that the staff can understand the temperature inside the vacuum coating chamber 1, and then the controller 12 can control the motor 405, the circulating water pump 10 and the temperature sensor 11, and then the observation window 14 can facilitate the staff to observe the cooling condition of the coated parts inside the vacuum coating chamber 1, and then it is convenient for the staff to control the motor 405 to drive the storage plate 408 to move, and then the tilting block 15 can guide the coolant entering the collection box 7, so that the coolant can smoothly enter the circulating water pipe 9, and then the support column 16 can provide support for the vacuum coating chamber 1, and the rubber pad 17 can increase the friction between the vacuum coating chamber 1 and the ground, and further improve the stability of the vacuum coating chamber 1.
