Description

Technical Field

[0001] The utility model relates to the technical field of metal plate coating equipment, in particular to an adjustable clamping device for metal plate coating. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to evaporate and condense on the surface of the coated part to form a thin film. When vacuum coating a metal plate, it is necessary to first clamp the metal plate with a clamping device and then place it inside the coating machine for coating.

[0003] For example, the utility model: "A vacuum coating clamping device for hardware accessories", with the announcement number: "CN217351517U", uses a sliding rod, a motor, a spindle, a gear sleeve, a clamping plate and a gear in coordination, so that the clamping plate can clamp hardware accessories of different specifications. The operation is convenient and labor-saving, and the clamping efficiency is improved. The pressure on the hardware accessories can be absorbed by the compression of the spring, thereby ensuring that the hardware accessories are not easily worn during clamping and improving the processing quality. However, during the implementation of this patent, after coating one side of the metal plate, the metal plate cannot be directly turned over, and the coated surface of the metal plate cannot be directly adjusted. The adjustability of the device is poor, and it is inconvenient to use. Utility Model Content

[0022] like Figure 1-2 As shown, sliding components 2 are installed at both ends of the U-shaped bottom plate 1, and a lifting plate 14 is slidably installed on the inner side of the sliding component 2, fixed rods 4 are installed at both ends of the top of the lifting plate 14, and the fixed rods 4 pass through the coated substrate 3 and extend to the outside of the coated substrate 3, and fixed springs 15 are installed at the bottom of the lifting plate 14, and the ends of the fixed springs 15 away from the lifting plate 14 are connected to the U-shaped bottom plate 1. After the rotation is completed, the elastic action of the fixed springs 15 pushes the lifting plate 14 to move upward, and the lifting plate 14 drives the fixed rods 4 to move together, and the fixed rods 4 can be inserted into the corresponding fixed holes 16 on the limiting disk 6, which can prevent the rectangular frame 10 and the metal plate from continuing to rotate during the coating process, which is beneficial to improving the stability of the device.

[0023] like Figure 1-2As shown, both ends of the rectangular frame 10 are provided with fixing screw holes 9, and the interior of the fixing screw holes 9 is threadedly installed with fixing screws 13, and the end of the fixing screws 13 close to the rectangular frame 10 is installed with fixing clamps 12, and both sides of the rectangular frame 10 are provided with coating openings 11, and the end of the fixing screws 13 away from the fixing clamps 12 is installed with handles. When in use, the metal plate is placed inside the rectangular frame 10, and then the staff can rotate the fixing screws 13 so that the fixing screws 13 move inside the fixing screw holes 9 through the threads, and the fixing screws 13 drive the fixing clamps 12 to move together, so that the two groups of fixing clamps 12 can be tightly fitted with the outer side of the metal plate, and metal plates of different lengths can be fixed by the two groups of fixing clamps 12. After the material evaporates, it can pass through the coating opening 11 into the interior of the rectangular frame 10, thereby facilitating the coating of the side of the metal plate.

[0024] Working principle:

[0025] When in use, the metal plate is placed inside the rectangular frame 10, and then the staff can rotate the fixing screw 13, so that the fixing screw 13 moves inside the fixing screw hole 9 through the thread, and the fixing screw 13 drives the fixing clamping plate 12 to move together, so that the two sets of fixing clamping plates 12 can be closely fitted with the outer side of the metal plate, and the metal plates of different lengths can be fixed by the two sets of fixing clamping plates 12;

[0026] After evaporating inside the coating machine, the material can condense on the surface of the metal plate, resulting in a thin film on the surface of the metal plate, thus completing the coating process;

[0027] After coating one side of the metal plate, the staff can push the lifting plate 14 downward, the lifting plate 14 compresses the fixing spring 15, and the lifting plate 14 drives the fixing rod 4 to move together, and the fixing rod 4 can be taken out from the fixing hole 16, so that the fixing rod 4 can release the limit of the limit disc 6, so that the limit disc 6 and the rotating rod 8 can rotate;

[0028] Then the staff can rotate the rectangular frame 10 to flip the metal plate, and can flip different sides of the metal plate to the top for coating;

[0029] After the rotation is completed, the staff releases the lifting plate 14. At this time, the elastic action of the fixed spring 15 pushes the lifting plate 14 to move upward, and the lifting plate 14 drives the fixed plug rod 4 to move together. The fixed plug rod 4 can be inserted into the corresponding fixed plug hole 16 on the limiting disk 6. By limiting the limiting disk 6 with the fixed plug rod 4, the rectangular frame 10 and the metal plate can be prevented from continuing to rotate during the coating process, which is beneficial to improving the stability of the device.
