Description

Technical Field

[0001] The invention belongs to the technical field of vehicle lamp coating, and in particular relates to a composite coating device for vehicle lamps. Background Art

[0002] The composite coating of automobile lights is a technology used to improve the surface performance and appearance of the lights. Through composite coating, the lights can have better wear resistance, weather resistance and light transmittance, and can also improve the appearance texture of the lights. This coating is usually achieved by coating a layer of transparent composite material on the surface of the lights. This material can not only prevent the surface of the lights from being affected by sunlight and oxidation, but also increase its hardness and wear resistance. The composite coating of automobile lights usually requires the use of professional equipment and processes to ensure the uniformity and quality of the coating.

[0003] Existing composite coating equipment for automobile lamps often has some defects: common sputtering coating equipment can only perform sputtering coating on one side of the lamp, because most of the lamps are curved structures, and the shape and size of the lamps will also make the single-sided sputtering uneven, resulting in unstable coating effect and affected coating quality; in addition, the existing lamp coating equipment does not have the function of cleaning residual impurities on the inner wall. A large amount of impurities will remain on the inner wall after long-term use of the equipment, and regular cleaning is required, which is time-consuming and labor-intensive. At the same time, the coating process will also be affected by impurities, affecting the coating effect; finally, the existing sputtering equipment uses inert gas to maintain a vacuum environment or assist the sputtering process, so the pressure change of the inert gas will directly affect many aspects of the coating process. The existing sputtering equipment can only increase or decrease the gas flow rate simply according to the pressure of the reaction gas in the box. It takes time to adjust the air pressure in large-scale equipment, and it cannot directly and effectively affect the coating, resulting in instability of the coating effect and affecting the composition of the coating. Higher air pressure may cause the sputtering material to react with the inert gas, thereby changing the composition and chemical structure of the film, etc. Summary of the invention

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention changes the rotation angle of the lamp coating and realizes double-sided coating through the design of a flipping mechanism. The existing coating equipment hangs the lamp on a hook, and then the hook rotates to the coating position of the coater for coating. The rotation angle and the uniformity of the sputtering coating cannot be controlled. The present invention drives the fourth bevel gear to rotate through a linkage rod, and the fourth bevel gear drives the driving wheel to rotate through the third bevel gear. Due to the special structure of the driving wheel and the driven block, the driving wheel drives the driven block to rotate intermittently, and the driven block drives the cross column to rotate.

[0016] 2. The present invention realizes the cleaning of residual impurities on the inner wall of the equipment through the design of the disc, the rotating block and the brush rod. The rotation of the rotating rod drives the first roller to rotate, and the first roller drives the second roller and the disc to rotate through the belt. The disc realizes the swinging motion of the rotating block through the action of the limit block, thereby realizing the semi-circular motion of the brush rod. Under the action of the limit block, the rotation angle of the rotating block will not interfere with the sputtering device that is coating the car lights, and the influence of excessive rotation of the brush rod on the coating process is avoided. When the equipment is running, it will not affect the normal coating of the car lights by the equipment, and the inner wall can be cleaned at the same time, which helps to ensure that the coating process of the car lights will not be affected by foreign impurities, so as to obtain a more uniform and high-quality coating effect.

[0017] 3. The present invention controls the pressure of the inert gas in the box through a gas flow control valve. When the air pressure in the box increases, the rate at which ions bombard the target material increases, and the pressure sensor causes the guide rod to move downward to cut off the source of the inert gas. At this time, the guide rod drives the telescopic rod to move downward through the cross bar, and changes from a state in which the first movable gear is meshed with the second movable gear to a state in which the first movable gear is meshed with the third movable gear, thereby accelerating the rotation speed of the rotating rod and avoiding the effect of the coating being affected by excessive thickness. Similarly, if the air pressure in the box decreases, the rotation speed of the rotating rod will be reduced, so that the sputtering equipment can effectively and quickly adjust the influence of the air pressure on the coating, thereby making the coating of the car lights more uniform.
