[0002] New energy vehicle glass is widely used in the entire body. In order to improve the glass and its performance, it needs to be plated. Most of them need to be plated by vacuum magnetron sputtering coating equipment, which involves multiple processes such as cleaning, vacuuming and sputtering coating. The purpose of cleaning is to remove impurities such as dust and fingerprints on the glass to ensure the integrity of subsequent sputtering coating. However, the existing vacuum magnetron sputtering coating equipment has the following problems when used: The existing vacuum magnetron sputtering coating equipment, when cleaning, mostly cleans the glass surface by high-pressure washing, but it is not convenient to scrape the cleaned glass. With top cleaning, most of the water stains still remain on the surface. On the one hand, impurities are easy to precipitate again, and on the other hand, the subsequent drying time is increased, affecting the overall efficiency. At the same time, the specifications of glass used in different areas of the vehicle are different. The existing vacuum magnetron sputtering coating equipment is not convenient for efficient and energy-saving cleaning of glass of different specifications. Most of them adopt the form of reciprocating spraying of the nozzle for cleaning. When cleaning glass of different specifications, the cleaning range is not convenient to adjust. On the one hand, it affects the glass cleaning time, and on the other hand, a large amount of cleaning fluid is wasted.

[0014] Preferably, the method comprises the following steps: S1: According to the width of the glass, the hydraulic cylinder pushes the active rod to move, and the active rod drives the first screw to rotate through the second gear roller, and multiple mounting seats on the outside move inward. The variable pitch screw is set to ensure that the distances of multiple mounting seats after moving are the same; S2: The movement of the mounting seat drives the mounting sleeve to move through the first gear roller and the rack. The bottom of the rack contacts the inclined surface of the push plate, so that the rack is forced to move upward, and the nozzle is driven to rotate through the first gear roller to adjust its initial angle; S3: The movement of the active rod drives the second piston rod to move in the oil chamber through the push head.

S5: The built-in motor drives the second screw to rotate, and the second screw drives the base to move.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention performs alternate spraying and scraping from the bottom of the glass. The second screw drives the base to move, and the pressure sensor cooperates with the two positioning plates to realize timely reciprocating movement of the base according to the glass specifications. The scraper made of silicone material on the base scrapes off water stains and impurities on the bottom of the glass. In this way, on the one hand, water stains on the bottom of the glass can fall off by themselves, and on the other hand, the scraper scrapes off the remaining water stains, and then the subsequent hot air drying can ensure the cleanliness of the glass, while greatly reducing the cleaning and drying time and improving the cleaning efficiency; 2. The present invention drives the oil tank and the first piston rod to move up and down through the electric push rod, and can drive the rack to move up and down through the bottom rod and the mounting sleeve, and mesh with the first gear roller to realize the reciprocating swing of the nozzle, so as to perform large-area synchronous and rapid cleaning of the bottom of the glass. When it is suitable for glasses of different specifications, the movement of the active rod drives the second piston to move through the push head. In addition to adjusting the positions of the two positioning plates, it can also drive the first screw to rotate, adjust the overall span of multiple nozzles, and adjust the initial angle of the nozzle through the push plate and the rack. Furthermore, the initial position of the first piston can be adjusted through the oil chamber and the oil tank, so that the electric push rod outputs a constant stroke, which can adjust the up and down movement amplitude of the rack, and then adjust the swing amplitude of the nozzle, that is, the smaller the glass width is, the smaller the initial inclination angle of the nozzle is, and the smaller the swing amplitude of the nozzle is, thereby improving the cleaning efficiency without causing waste of cleaning fluid.

8. The automotive glass product coating device according to claim 7, characterized in that: The adjustment assembly comprises an active rod (19), the active rod (19) being slidably mounted inside the front and rear sides of the mounting frame (2) through a hydraulic cylinder, a second gear roller (20) being meshed at the bottom of the active rod (19), the second gear roller (20) being connected to the first screw rod (6), a push head (211) being fixed inside the active rod (19), a second piston rod (212) being arranged on the movable track of the push head (211), the second piston rod (212) being slidably arranged in an oil chamber (213), the oil chamber (213) being embedded inside the front and rear sides of the mounting frame (2), the oil chamber (213) being connected to the oil tank (162) through a hose, and the inner side of the outer protrusion of the second piston rod (212) being connected to the positioning plate (182) through a longitudinal rod (214).

9. The automotive glass product coating device according to claim 8, characterized in that: The push head (211) is designed as a right-angled trapezoidal structure, and the inclined surface of the push head (211) contacts the outer protruding position of the second piston rod (212).

10. A method for cleaning an automobile glass product coating device, applicable to an automobile glass product coating device as claimed in claim 9, characterized in that: The method comprises the following steps: S1: According to the width of the glass, the hydraulic cylinder pushes the active rod (19) to move, and the active rod (19) drives the first screw (6) to rotate through the second gear roller (20), so that the outer plurality of mounting seats (8) move inward, and the variable pitch screw is set to ensure that the plurality of mounting seats (8) move to the same distance after movement; S2: The mounting seat (8) moves, and the mounting sleeve (12) is driven to move through the first toothed roller (15) and the rack (13), and the bottom of the rack (13) contacts the inclined surface of the push plate (14), so that the rack (13) is forced to move upward, and the nozzle (9) is driven to rotate and adjust its initial angle through the first toothed roller (15); S3: The active rod (19) moves, and the push head (211) drives the second piston rod (212) to move in the oil chamber (213). On the one hand, the oil tank (162) drives the first piston rod (163) to move downward to adjust the initial position of the first piston rod (163). On the other hand, the longitudinal rod (214) adjusts the initial position of the positioning plate (182); S4: placing the glass on the guide roller (3) and conveying it inwards, the guide roller (3) starts to rotate and reset when it reaches the innermost side, and the cleaning liquid is sprayed out through the nozzle (9) by an external liquid spraying device, and the oil tank (162) and the first piston rod (163) are pushed up and down by the electric push rod (161), and the first piston rod (163) cooperates with the elastic telescopic rod (10) to drive the bottom rod (11) to move up and down, and the rack (13) is meshed with the first toothed roller (15) to drive the nozzle (9) to swing back and forth, so as to clean the bottom of the glass between the adjacent guide rollers (3); S5: The built-in motor drives the second screw (17) to rotate, and the second screw (17) drives the base (18) to move, and the scraper (181) contacts the bottom surface of the cleaned glass to scrape away the residual liquid and stains thereon, and the pressure sensor on the base (18) contacts the positioning plate (182), and the sensing position controls the motor to rotate forward and reverse through the controller to ensure the reciprocating movement of the base (18); S6: The glass is cleaned and scraped twice by two sets of nozzles (9) and scraping rods (181), and then at the outermost position, the bottom surface of the glass is dried with hot air by two sets of drying cylinders (5), and then the glass is turned over and cleaned again.
