Technical Field
[0001] This utility model relates to the field of magnetron sputtering coating technology, and more specifically, to a magnetron sputtering coating device for the surface of plastic parts. Background Technology
[0002] Magnetron sputtering is a type of physical vapor deposition. General sputtering methods can be used to prepare various materials such as metals, semiconductors, and insulators. It has advantages such as simple equipment, easy control, large coating area, and strong adhesion. Magnetron sputtering, which was developed in the 1970s, has achieved high speed, low temperature, and low damage. Because high-speed sputtering is performed under low pressure, it is necessary to effectively improve the ionization rate of the gas. Magnetron sputtering increases the plasma density by introducing a magnetic field on the surface of the target cathode and using the magnetic field to confine charged particles, thereby increasing the sputtering rate.

The interior space of the coating chamber is small, which greatly limits its practical operation, makes it extremely inconvenient to use, and affects the installation efficiency. In view of the above problems, a solution is proposed below. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a magnetron sputtering coating device for plastic parts, which can be easily installed and improve efficiency.
[0006] To solve the above problems, the present invention adopts the following technical solution.
[0007] A magnetron sputtering coating apparatus for plastic parts includes a base, on which a coating chamber is mounted. The coating chamber is a vertically arranged cylinder with an inlet on its arc surface. A sealing door is hinged to the inlet. Two connecting rings are arranged vertically inside the coating chamber, rotatably connected to the coating chamber. A mounting frame is fixedly connected between the two connecting rings. A movable frame is provided on one side of the mounting frame, and the movable frame slides with the mounting frame. Clamping components are symmetrically mounted on the movable frame. A magnetron target is provided on the side of the coating chamber. A motor for driving the connecting rings to rotate is mounted on the top of the coating chamber.
[0008] Preferably, the clamping component includes a clamping rod, an X-shaped connecting rod, a sliding rod, and a pressure plate. The clamping rod is slidably arranged inside the movable frame.

The movable frame has a sliding groove, and the sliding rod is slidably arranged inside the sliding groove. One end of the sliding rod is fixedly connected to the leg of the X-shaped connecting rod that is slidably engaged with the movable frame. The pressure plate is threaded onto the other end of the sliding rod, and the pressure plate is in contact with the side of the movable frame.
[0009] Preferably, a connecting rod is rotatably provided on the outside of the coating chamber, a connecting block is fixedly connected to the sealing door, a connecting port is provided on the connecting block, the connecting rod and the connecting port are detachably connected, a fastening plate is threaded to one end of the connecting rod, and the fastening plate and the side of the connecting block are in contact with each other.

[0011] Preferably, a plurality of limiting rods are slidably arranged on the mounting frame, the limiting rods are fixedly connected to the movable frame, and springs are sleeved on the limiting rods to ensure the stability of the positions of the mounting frame and the movable frame.

[0013] Preferably, a controller is installed on the base, and the motor and the magnetic target are electrically connected to the controller.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] I. This solution places the feed inlet on the side of the coating chamber, and the movable frame for mounting plastic parts directly corresponds to the feed inlet, making it convenient for users to install and load materials. The sliding fit between the movable frame and the mounting frame allows the movable frame to be closer to the feed inlet, further reducing the difficulty of loading materials. At the same time, the motor can drive the connecting ring to rotate, thereby driving the plastic parts to rotate, thus completing the coating of both sides of the plastic without the need for manual removal and flipping, making it simple to use.
[0016] 2. By moving one of the legs at one end of the X-shaped connecting rod, when the two legs at one end of the X-shaped connecting rod come closer to each other, the two ends of the X-shaped connecting rod will move away from each other, thereby driving the clamping rod away from the moving frame.

[0030] Example 1:
[0031] Please see Figure 1-6 A magnetron sputtering coating apparatus for plastic parts includes a base 1, a controller 27 mounted on the base 1, and a coating chamber 2 mounted on the base 1, located to one side of the controller 27. The coating chamber 2 is a vertically arranged cylinder. An inlet pipe 24 and an exhaust pipe 25 are respectively installed on the side of the coating chamber 2. Valves 26 are installed on both the inlet pipe 24 and the exhaust pipe 25. The valves 26 are electrically controlled and electrically connected to the controller 27. The exhaust pipe 25 is used to evacuate the inside of the coating chamber 2, and the inlet pipe 24 is used to replenish the inside of the coating chamber 2 with nitrogen. The opening and closing of the inlet pipe 24 and the exhaust pipe 25 are controlled by the valves 26. A magnetron target 9 is provided on the side of the coating chamber 2 and is electrically connected to the controller 27. The arc of the coating chamber 2... A feed inlet 3 is provided on the surface, corresponding to the magnetic target 9. A sealing door 4 is hinged at the feed inlet 3. A connecting rod 16 is rotatably provided on the outside of the coating chamber 2. A connecting block 17 is fixedly connected to the sealing door 4. A connecting port 18 is provided on the connecting block 17. The connecting rod 16 and the connecting port 18 are detachably connected. A fastening plate 19 is threaded to one end of the connecting rod 16. The fastening plate 19 and the side of the connecting block 17 are in contact with each other. The connecting rod 16 can be easily rotated into the connecting port 18 through the connecting port 18. By rotating the fastening plate 19, the fastening plate 19 and the connecting block 17 can be made in contact, thereby limiting the position of the connecting block 17, that is, ensuring the sealing effect of the sealing door 4 on the feed inlet 3, and ensuring that there is no leakage when vacuuming or replenishing nitrogen.
[0032] The coating chamber 2 contains two vertically arranged connecting rings 5, which are rotatably arranged with the coating chamber 2. An annular guide ring 20 is installed inside the coating chamber 2. An annular guide groove 21 is formed on the outer arc surface of the connecting rings 5, and the guide ring 20 is rotatably arranged inside the guide groove 21. A motor 10 is installed at the top of the coating chamber 2 to drive the rotation of the connecting rings 5. The motor 10 is electrically connected to a controller 27. The motor 10 can drive the connecting rings 5 to rotate, thereby driving the subsequent moving frame 7 to rotate. The angle of the plastic parts on the moving frame 7 can be adjusted, thus achieving coating on both sides of the plastic parts without manual flipping. A mounting frame 6 is fixedly connected between the two connecting rings 5. One side of the mounting frame 6 is equipped with... A movable frame 7 is provided, which slides with the mounting frame 6. Several limiting rods 22 are slidably arranged on the mounting frame 6. The limiting rods 22 are fixedly connected to the movable frame 7. A stop is provided at the other end of the limiting rod 22. A spring 23 is sleeved on the limiting rod 22 to ensure the stability of the position of the mounting frame 6 and the movable frame 7. The two ends of the spring 23 are in contact with the stop and the mounting frame 6 respectively. The movable frame 7 corresponds to the feed port 3, and the movable frame 7 can slide with the mounting frame 6, allowing the movable frame 7 to move out of the feed port 3 for easy feeding. The limiting rods 22 can ensure the stability of the movement of the movable frame 7. When the movable frame 7 is reset, the elastic force of the spring 23 can prevent the movable frame 7 from moving on its own.
[0033] A clamping component 8 is symmetrically mounted on the movable frame 7. The clamping component 8 includes a clamping rod 11, an X-shaped connecting rod 12, a sliding rod 13, and a pressure plate 14. The clamping rod 11 is slidably arranged inside the movable frame 7. The X-shaped connecting rod 12 is arranged between the clamping rod 11 and the movable frame 7. The X-shaped connecting rod 12 includes two rotating rods. The middle parts of the two rotating rods are rotatably engaged through a rotating shaft, so that the two rotating rods form an X shape and can rotate. One of the two support legs at one end of the X-shaped connecting rod 12 is rotatably engaged with the movable frame 7. One of the two legs of the X-shaped connecting rod 12 is slidably engaged with the movable frame 7. One of the two legs of the other end of the X-shaped connecting rod 12 is rotatably engaged with the clamping rod 11. The other of the two legs of the other end of the X-shaped connecting rod 12 is slidably engaged with the clamping rod 11. The movable frame 7 is provided with a sliding groove 15. The sliding rod 13 is slidably arranged inside the sliding groove 15. One end of the sliding rod 13 is fixedly connected to the leg of the X-shaped connecting rod 12 that is slidably engaged with the movable frame 7. The pressure plate 14 is threadedly arranged on the other end of the sliding rod 13. The pressure plate 14 and the side of the movable frame 7 are in contact with each other.
[0034] By moving one of the legs at one end of the X-shaped connecting rod 12, when the two legs at one end of the X-shaped connecting rod 12 come closer to each other, the two ends of the X-shaped connecting rod 12 will move away from each other, thereby driving the clamping rod 11 away from the moving frame 7. That is, the plastic part can be clamped by the two clamping rods 11. The position of the X-shaped connecting rod 12 is ensured by the friction between the pressure plate 14 and the moving frame 7, thereby ensuring the clamping stability of the clamping rod 11.
[0035] Working principle:
[0036] Before use, by rotating the fastening plate 19, the fastening plate 19 and the connecting rod 16 are threaded together. When the fastening plate 19 rotates, it can move relative to the threaded rod, that is, the fastening plate 19 moves away from the connecting plate. Rotating the connecting rod 16 causes the connecting rod 16 to move out of the connection port 18, removing the restriction on the connecting block 17. This makes it easy to rotate the sealing door 4, expose the feed port 3, and pull out the moving frame 7 so that the moving frame 7 is close to the feed port 3 for easy loading. The plastic part is placed between the clamping parts 8 on the two moving frames 7. Moving the slide bar 13 causes one of the legs of the X-shaped connecting rod 12 to move closer to the other leg, thus moving the two ends of the X-shaped connecting rod 12 away from each other. This pushes the clamping rod 11 to clamp the plastic part. Then, by rotating the pressure plate 14, the threaded engagement between the pressure plate 14 and the slide bar 13 causes the pressure plate 14 to move along the axis of the slide bar 13. The pressure plate 14 acts on the side of the moving frame 7, and the friction between the pressure plate 14 and the moving frame 7 fixes the position of the slide bar 13. To ensure the stability of the plastic part clamping, the X-shaped connecting rod 12 is fixed in shape. The moving frame 7 is reset, and the spring 23 ensures the stability of the moving frame 7 and the mounting frame 6. The sealing door 4 is closed, and the connecting rod 16 and the fastening plate 19 are reset to ensure the stability of the sealing door 4. The exhaust pipe 25 is connected to the vacuum generator, and the inlet pipe 24 is connected to the external nitrogen cylinder. The controller 27 controls the valve 26 of the exhaust pipe 25 to open and the valve 26 of the inlet pipe 24 to close. The vacuum generator draws a vacuum inside the coating chamber 2. After vacuuming is completed, the controller 27 controls the two valves 26 to switch states, and the nitrogen cylinder replenishes nitrogen into the coating chamber 2. After completion, the controller 27 controls both valves 26 to be closed. The controller 27 controls the magnetron sputtering target 9 to coat the plastic part. When one side of the plastic part is coated, the controller 27 controls the motor 10 to start. The motor 10 drives the connecting ring 5 to rotate 180 degrees, so that the magnetron sputtering target 9 can also coat the other side of the plastic part without manual adjustment, making it convenient to use.
