It is widely used in optics, electronics, machinery, biology, and other fields. Existing vacuum coating machines typically have only one coating chamber. After coating, the workpiece needs to be removed from the chamber, which disrupts the vacuum environment, making continuous coating impossible and resulting in low production efficiency. Therefore, a multi-station continuous vacuum coating device is proposed. Utility Model Content

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a multi-station continuous vacuum coating equipment, including an outer cylinder 1 with its opening facing upwards. A groove 2 is provided on one side of the outer surface of the outer cylinder 1. A coating machine 4 is fixedly connected to the side of the outer cylinder 1 opposite to the groove 2. A rotating column 13 is rotatably connected to the center inside the outer cylinder 1. Multiple coating boxes 8 are fixedly connected to the outer surface of the rotating column 13. The side of the coating box 8 away from the rotating column 13 is open and has an arc-shaped structure that matches the inner surface of the outer cylinder 1. Each coating box 8 is equipped with an air extraction mechanism.

[0018] Furthermore, support blocks 14 are fixedly connected to both sides of the lower surface of the outer cylinder 1, and a motor 3 is fixedly connected to the center of the lower surface of the outer cylinder 1. The output shaft of the motor 3 passes through the bottom surface of the outer cylinder 1 and is fixedly connected to the rotating column 13.

[0019] In this embodiment, by pre-reserving a groove 2 on the surface of the outer cylinder 1, it is convenient to place workpieces into or remove workpieces from the coating box 8 through the groove 2. The motor 3 drives the rotating column 13 and the coating box 8 to rotate, so that the coating box 8 passes through the coating machine 4 in sequence. The vacuum mechanism is used to evacuate the inside of the coating box 8 to a vacuum state, thereby realizing continuous vacuum coating and improving production efficiency.

[0020] Furthermore, the suction mechanism includes a piston plate 9 installed inside the coating chamber 8. A connecting rod 10 is fixedly connected to the upper surface of the piston plate 9. The upper end of the connecting rod 10 extends through to the top of the coating chamber 8 and is fixedly connected to a magnetic block 7. A fixed seat 5 is fixedly connected to the upper surface of the coating machine 4. An electromagnet 6 is fixedly connected to the top of the fixed seat 5. The electromagnet 6 is located in the moving direction of the magnetic block 7, and one end of the electromagnet 6 extends to the outside of the coating area. A spring 11 is sleeved on the outer surface of the connecting rod 10. The upper end of the spring 11 is fixedly connected to the coating chamber 8, and the lower end of the spring 11 is fixedly connected to the piston plate 9.

[0021] Furthermore, a groove is provided on the top of the coating box 8, and the connecting rod 10 passes through the groove and is fitted with it with clearance.

[0022] In this embodiment, when the motor 3 drives the coating box 8 to move to the side of the coating machine 4, the electromagnet 6 attracts the magnetic block 7 on the coating box 8 and moves it upward, thereby driving the connecting rod 10 and the piston plate 9 to move upward, evacuating the space between the bottom of the coating box 8 and the piston plate 9 into a vacuum state. The coating machine 4 can then coat the workpiece in a vacuum environment. Since one end of the electromagnet 6 extends outside the coating area, the electromagnet 6 has already attracted the magnetic block 7 before the coating box 8 moves into the coating area, evacuating the interior of the coating box 8 into a vacuum state to facilitate continuous coating. In addition, when the piston plate 9 moves upward, the spring 11 is compressed. When the magnetic block 7 rotates to separate from the electromagnet 6, the spring 11 can drive the piston plate 9 to reset.

[0023] Furthermore, sealing strips 12 are fixedly connected to the outer surfaces of the coating box 8 and the piston plate 9, and the sealing strips 12 slide and seal with the inner surface of the outer cylinder 1.

[0024] In this embodiment, by setting a sealing strip 12, when the coating box 8 rotates into the outer cylinder 1, the sealing between the coating box 8, the piston plate 9 and the outer cylinder 1 can be guaranteed.
