[0023] Operator can install optical head cover in the inside of installation hole 4, when coating machine starts, positioning rod 7 will be rotated, and then positioning rod 7 can drive fixed block 5 to rotate by universal joint 6, so that coating disc 3 and bearing 2 can rotate at uniform speed, so that coating material can be uniformly deposited on the surface of optical head cover, improve the uniformity of coating.

[0024] Wherein, the outer surface of base 1 is fixedly installed with first supporting rod 8, the number of first supporting rod 8 is two, the size of two first supporting rods 8 is same, first supporting rod 8 and the plane where base 1 is located form forty-five degree angle.

[0025] As a kind of technical optimization scheme of the utility model, by setting first supporting rod 8, two first supporting rods 8 can support the whole base 1.

[0026] The second supporting rod 9 is fixedly installed on the front side of the top of the base 1, the length of the second supporting rod 9 is greater than the length of the first supporting rod 8, and the second supporting rod 9 forms a forty-five degree angle with the plane where the base 1 is located.

[0027] As a technical optimization scheme of the utility model, the second supporting rod 9 is arranged, so that the base 1 is in an inclined state as a whole.

[0028] The top of the second supporting rod 9 is bolt-connected with a coating machine rotary top plate 10, and the bottom of the coating machine rotary top plate 10 is movably installed with a coating machine body 11.

[0029] As a technical optimization scheme of the utility model, when the coating machine rotary top plate 10 rotates, the base 1 is driven to rotate through the second supporting rod 9 and the first supporting rod 8.

[0030] The bottom of the coating machine rotary top plate 10 is bolt-connected with the top of the first supporting rod 8, and the middle of the lower surface of the coating machine rotary top plate 10 is bolt-connected with the top of the positioning rod 7.

[0031] As a technical optimization scheme of the utility model, when the coating machine rotary top plate 10 rotates, the coating machine rotary top plate 10 drives the positioning rod 7 to rotate, so that the positioning rod 7 can drive the coating disc 3 to rotate through the fixing block 5 and the universal joint 6.

[0036] Then, the operator installs the optical head cover inside the mounting hole 4, starts the coating machine body 11 to make the coating machine rotary top plate 10 rotate at a constant speed, so that the coating machine rotary top plate 10 drives the base 1 to rotate at a constant speed as a whole through the first supporting rod 8 and the second supporting rod 9. Since the included angle between the first supporting rod 8 and the second supporting rod 9 and the plane where the base 1 is located is forty-five degrees, the coating disc 3 and the coating machine rotary top plate 10 form an included angle of forty-five degrees. When the coating machine rotary top plate 10 rotates at a constant speed, the coating disc 3 will be driven to rotate through the positioning rod 7 and the universal joint 6, so that the coating disc 3 drives the optical head cover to rotate at a constant speed, so that the coating material can better adhere to the surface of the optical head cover, and form a dense and firm film layer.
