In the automated production process of silicon wafers, stress is easily generated during the feeding process of silicon wafers, which in turn causes damage to the silicon wafers and fractures during subsequent processing. The coating thickness on the surface of the silicon wafer directly determines the performance of the finished product, and the coating thickness needs to be uniform. Existing roll coating equipment is prone to edge effects, resulting in uneven film thickness, which affects subsequent processing and further affects device performance.

The above-mentioned horizontal driving device drives the first mobile platform and the second mobile platform to move back and forth alternately between the loading device and the discharging device. The above-mentioned vertical driving device drives the first mobile platform and the second mobile platform to alternately rise and fall in the vertical direction. During the working process of the present invention, the material is placed on the feeding device, and the feeding device conveys the material to the rolling device. At the same time, the horizontal driving device drives the first mobile platform to move toward the feeding device, and the first mobile platform abuts against the feeding device. The feeding device transfers the material to the first mobile platform, and then the horizontal driving device drives the first mobile platform to move to the lower side of the rolling device for coating. At the same time, the vertical driving device drives the second mobile platform to descend, and the second mobile platform and the first mobile platform are dislocated. The horizontal driving device drives the second mobile platform to move toward the feeding device, and the second mobile platform rises. The second mobile platform abuts against the feeding device, and the feeding device conveys the material to the top surface of the second mobile platform. At this time, the material on the top surface of the first mobile platform has been rolled, and the horizontal driving device drives the first mobile platform to move toward the discharging device. The first mobile platform contacts the discharging device, and the discharging device delivers the material that has been rolled on the top surface of the first mobile platform. At the same time, the second mobile platform moves toward the rolling device for rolling, and the vertical driving device drives the first mobile platform to descend, and the horizontal driving device drives the first mobile platform to move to the feeding device to receive the material.

The arc-shaped guide rail is connected to the top surface of the upper support plate, and a top plate is provided on the upper side of the arc-shaped guide rail, and the top plate and the arc-shaped guide rail are slidably connected through a slider. The two ends of the double roller are respectively connected to the top surface of the top plate. A gear is movably connected to the shaft on the bottom surface of the top plate, and an arc-shaped rack is connected to the top surface of the upper support plate, and the gear and the arc-shaped rack are meshed.

A motor is provided on the upper side of the top plate, and the motor shaft of the motor passes through the top plate and is driven and connected to the gear, and the motor drives the top plate to move along the arc-shaped guide rail through the gear.
[0012] Further, in the above-mentioned angle-adjustable roller coating device, the first movable platform is provided with a first groove. The first groove is arranged along the driving direction of the horizontal driving device. The second movable platform is provided with a second groove. The second groove is arranged along the driving direction of the horizontal driving device. The loading device is provided with a loading support arm, and the conveyor belt provided by the loading device bypasses the outer side of the loading support arm, and the conveyor belt provided by the loading device supports and conveys the material.

A movable scraper and a fixed scraper are respectively provided on the upper sides of the fixed roller and the movable roller. The movable scraper and the fixed scraper are driven to rotate separately by the motor, and the thickness of the paint layer on the fixed roller and the movable roller is controlled separately. By adjusting the gap between the fixed roller and the movable roller, the coating thickness can be accurately controlled, and the movable roller can eliminate the defects caused by the fixed roller, improve the coating quality, and improve the coating efficiency. The moving scraper and the fixed scraper remove excess paint from the surface of the fixed roller and the moving roller, adjust the thickness of the paint layer on the fixed roller and the moving roller, control the thickness of the coating film, make the paint evenly distributed on the surface of the fixed roller and the moving roller, prevent uneven paint phenomena such as streaks, bubbles or particles, and improve the flatness of the coating film.
