The coating assembly includes a mounting base, a motor mounted on the right side surface of the mounting base, and a lead screw mounted on the left end of the motor. A cleaning assembly is disposed at the right edge of the upper surface of the coating plate. This invention, by incorporating the coating assembly, allows the motor to drive the lead screw to rotate, causing the coating tube to slowly move to one side. Simultaneously, an electric valve opens, allowing photoresist to flow into the coating tube and slowly flow out through a fine orifice, thereby automating the coating process on the LCD substrate used in LCD production. The cleaning assembly's cylinder extends, driving a cleaning pad to clean the LCD substrate, effectively removing surface contaminants.

The screw 14 is rotated to move the cleaning pad 16 to a suitable height. Then, the cylinder 5 is activated to move the fixing block 13. The movement of the fixing block 13 moves the cleaning pad 16 to clean the surface of the LCD substrate. Then, the motor 6 is activated to drive the screw 11 to rotate. The rotation of the screw 11 moves the moving block 12 in the mounting base 7. The movement of the moving block 12 moves the coating tube 9 via the moving rod 18. The electric valve 10 is opened, and the photoresist in the photoresist tank 8 enters the coating tube 9 and drips onto the LCD substrate through the fine hole 17. With the coating assembly 2 in place, when the coating tube 9 moves and drips the photoresist onto the LCD substrate, the motor 26 is activated to drive the screw 27 to rotate.

The coating tube 9 moves and brushes the light resist dripping onto the LCD substrate through the brush 213, so that the light resist can be evenly coated onto the surface of the LCD substrate, improving the coating quality. The receiving box 23 can collect the light resist dripping when the brush 213 is not in use. To prevent light-blocking agent from dripping onto the coating plate 1 when the brush bristles 213 are not in use, the receiving box 23 can be removed from the groove 25 at the top of the coating plate 1 for cleaning by holding the handle 24.

[0032] The difference between this embodiment and embodiment 1 is that the clamping assembly 3 includes a clamping plate 31, a rectangular groove 32, a motor 33, a bidirectional lead screw 34, and a slide block 35. The upper end of the coating plate 1 is provided with a rectangular groove 32, one end of which is equipped with a motor 33. The output end of the motor 33 is provided with a bidirectional lead screw 34. The two sides of the surface of the bidirectional lead screw 34 are threadedly connected to the slide block 35, and the upper end of the slide block 35 is fixed with a clamping plate 31.

[0033] By adopting the above technical solution, the liquid crystal display substrate to be coated is placed between two clamping plates 31 on the coating plate 1. The motor 33 is turned on to drive the bidirectional lead screw 34 to rotate. The rotation of the bidirectional lead screw 34 causes the two slide blocks 35 to move closer to each other in the rectangular groove 32. The two slide blocks 35 move and clamp the liquid crystal display substrate on the coating plate 1 through the clamping plates 31. By setting the clamping component 3, the liquid crystal display substrate to be coated can be clamped and fixed, avoiding displacement of the liquid crystal display substrate when cleaning the surface of the liquid crystal display substrate.

[0034] Specifically, the side of the slide 35 is in close contact with the inner wall of the rectangular groove 32, and the two slides 35 are threaded to the bidirectional lead screw 34 in opposite directions.

[0035] By adopting the above technical solution, the slide block 35 moves more stably in the rectangular groove 32, and the rotation of the bidirectional lead screw 34 can drive the two slide blocks 35 to move towards each other.

[0036] In this embodiment, by setting the clamping component 3, the liquid crystal display substrate to be coated is placed between the two clamping plates 31 on the coating plate 1. The motor 33 is turned on to drive the bidirectional lead screw 34 to rotate. The rotation of the bidirectional lead screw 34 causes the two slide blocks 35 to move closer to each other in the rectangular groove 32. The two slide blocks 35 move and clamp and fix the liquid crystal display substrate on the coating plate 1 through the clamping plates 31. By setting the clamping component 3, the liquid crystal display substrate to be coated can be clamped and fixed, avoiding displacement of the liquid crystal display substrate when cleaning the surface of the liquid crystal display substrate.

Its working principle is to place the liquid crystal display substrate onto the coating plate 1, corresponding to the coating tube 9 and cleaning pad 16. Positioning the cleaning pad 16 at the appropriate height by rotating lead screw 14, cylinder 5 can then be activated to move fixing block 13. The movement of fixing block 13 moves cleaning pad 16, which cleans the surface of the LCD substrate. Then, motor 6 is activated to drive lead screw 11 to rotate. The rotation of lead screw 11 moves moving block 12 in mounting base 7. The movement of moving block 12 moves coating tube 9 via moving rod 18. Electric valve 10 is opened, and photoresist in photoresist tank 8 enters coating tube 9 and drips onto LCD substrate through fine hole 17.

[0039] The working principle and usage process of this utility model: When using the coating device for LCD screen processing, install the device in a suitable position, place the LCD substrate on the coating plate 1 at the position corresponding to the coating tube 9 and the cleaning pad 16, rotate the lead screw 14 to push the cleaning pad 16 to a suitable height, then open the cylinder 5 to push the fixing block 13 to move. The movement of the fixing block 13 drives the cleaning pad 16 to clean the surface of the LCD substrate. Then, turn on the motor 6 to drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the moving block 12 to move in the mounting base 7.

By setting the coating assembly 2, when the coating tube 9 moves and drips the photoresist onto the LCD substrate, the second motor 26 drives the screw 27 to rotate. The rotation of the screw 27 drives the slide plate 28 to move downward in the fixed frame 22. The movement of the slide plate 28 pushes the base plate 211 downward through the slide rod 210. The base plate 211 pushes the brush 213 at the lower end of the connecting plate 212 to move to a suitable height, and then the second motor 26 is turned off. The coating tube 9 moves through the brush 213. 3. The light-blocking agent dripping onto the LCD substrate can be brushed away, allowing it to be evenly coated onto the substrate surface and improving coating quality. The receiving box 23 can collect the light-blocking agent dripping from the brush 213 when not in use, preventing it from contaminating the coating plate 1. By gripping the handle 24, the receiving box 23 can be removed from the groove 25 at the top of the coating plate 1 for cleaning. By unscrewing the fixing bolts 293 from the fixing holes 294 of the folding plates 291 on both sides of the top of the connecting plate 212, the folding plates 291 can be removed from the placement groove 292 of the base plate 211, thereby... The connecting plate 212 and the brush bristles 213 can be disassembled for easy cleaning of the brush bristles 213. By setting the clamping assembly 3, the LCD substrate to be coated is placed between the two clamping plates 31 on the coating plate 1. The motor 33 is turned on to drive the bidirectional lead screw 34 to rotate. The rotation of the bidirectional lead screw 34 causes the two slides 35 to move closer to each other in the rectangular groove 32. The two slides 35 move and clamp the LCD substrate on the coating plate 1 through the clamping plates 31. By setting the clamping assembly 3, the LCD substrate to be coated can be clamped and fixed, avoiding displacement of the LCD substrate when cleaning the surface of the LCD substrate.
