[0014] A liquid coating process in an integrated light guide plate manufacturing process, S1: roller coating, firstly adjusting the distance between the liquid wiping roller and the light guide plate body, setting the rotation speed of the liquid wiping roller and the pressure between the liquid wiping roller and the light guide plate body;

[0015] S2: Scraper coating, adjust the angle between the scraper and the light guide plate body, and then adjust the pressure of the scraper on the light guide plate body;

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the pressure push plate and the horizontally installed top frame are lifted or lowered, the detachable tool holder is driven to lift or lower, thereby changing the position of the scraper on the detachable tool holder. At the same time, the central rotating connecting rod and the angle of the detachable tool holder can be adjusted by rotating the transmission gear, and the transmission gear angle is fixed after being adjusted by engaging with the rotating clamp on the transmission gear. The excess raw material liquid scraped by the scraper is discharged through the confluence trough and the drain pipe. The rotatable buckle design makes the fixing and adjustment process of the adjustment gear more convenient. Compared with the traditional fixing method, there is no need to use complex tools to disassemble and reinstall the fixing device. This convenient adjustment method can save a lot of time and energy.

[0019] 2. The raw liquid in the liquid storage tank is transported by the liquid delivery pump and then sprayed out through the liquid outlet. The servo motor drives the wiping roller to rotate. When the wiping roller rotates to reach the liquid inlet tank vertically upward, the raw liquid sprayed out of the liquid outlet enters the wiping roller through the liquid inlet tank. The raw liquid entering the wiping roller will collide with the inner impact gear ring and the outer impact gear ring. The raw liquid penetrates into the wiping roller through the outer impact gear ring. When the raw liquid is mixed in the wiping roller, due to the rotation of the wiping roller, the liquid will be subjected to strong shear force and friction in the roller. This mechanical force promotes the liquid molecules of different components to collide and disperse with each other better, avoiding agglomeration, ensuring the uniformity of mixing at the microscopic level, and making the final raw liquid more stable.

[0020] 3. The lifting height of the dryer is adjusted by lifting the lifting ring and the U-shaped height-adjusting frame structure on the positioning column, and the raised part of the elastic card plate is engaged on the positioning column, and the two height-adjusting ropes on one side are stretched to lift one side of the dryer, and the dryer is fixed after the angle is adjusted by moving and fixing the rope buckle on the height-adjusting rope. The angle adjustment can make the air outlet or radiation source of the drying equipment better align with the key parts of the dried object or the areas that are difficult to dry, so that the moisture can be evaporated more easily and the overall drying efficiency is improved.

[0045] A height-adjusting rope 46 is movably installed on the U-shaped height-adjusting frame 43, and the bottom end of the height-adjusting rope 46 is fixedly installed on the top of the dryer 45. A rope buckle 47 is movably installed on the height-adjusting rope 46. One side of the dryer 45 is lifted up by pulling the height-adjusting rope 46 and fixed by the rope buckle 47, so as to adjust the baking angle of the dryer 45.

[0046] Working principle:

[0047] Step 1: Adjust the height of the wiping roller 36 according to the coating needs to ensure that the wiping roller 36 is in contact with the light guide plate body 4, and at the same time prevent the wiping roller 36 from applying too much pressure to the light guide plate body 4. Screw the screw 33 to drive the lifting end block 32 threadedly connected thereto to rise and fall on the rounded rectangular frame 30, and at the same time drive the rotatable rod 35 and the servo motor 37 to rise and fall together. When the rotatable rod 35 rises and falls, it drives the wiping roller 36 to rise and fall together to ensure that the contact effect between the wiping roller 36 and the light guide plate body 4 is adapted. The raw material liquid in the liquid storage tank 25 is transported to the liquid dispensing tube 28 through the liquid delivery pump 27, and then sprayed out through the liquid outlet 29. The servo motor 37 drives the transmission wheel 38 to rotate, thereby driving The movable rotatable rod 35 rotates to drive the wiping roller 36 to rotate. When the wiping roller 36 rotates to reach the liquid inlet groove 3601 vertically upward, the raw material liquid sprayed from the liquid outlet 29 enters the wiping roller 36 through the liquid inlet groove 3601. The raw material liquid entering the wiping roller 36 will collide with the inner impact tooth ring 39 and the outer impact tooth ring 40 under the drive of the rotation of the wiping roller 36, so as to achieve mixing and uniform distribution of the raw material liquid in the wiping roller 36. The raw material liquid penetrates into the wiping roller 36 through the outer impact tooth ring 40, so as to achieve uniform distribution of the raw material liquid on the wiping roller 36, and then the contact between the wiping roller 36 and the light guide plate body 4 is realized to realize the coating operation of the light guide plate.

[0048] Step 2: The light guide plate body 4 continues to move to the corresponding position below the detachable tool holder 14, and the piston rod of the electric push rod 9 drives the pressure push plate 10 and the horizontally mounted top frame 7 to rise and fall. When the pressure push plate 10 and the horizontally mounted top frame 7 rise and fall, the detachable tool holder 14 is driven to rise and fall, thereby changing the position of the scraper 17 on the detachable tool holder 14, so that the scraper 17 can better scrape the raw material liquid on the light guide plate, and the scraper 17 on the detachable tool holder 14 can be disassembled by screwing the second locking bolt 18, and the detachable tool holder 14 as a whole can be disassembled by screwing the first locking bolt 16, ensuring the convenience of replacing the scraper-related accessories, and at the same time The angle of the central rotating connecting rod 13 and the detachable tool holder 14 can be adjusted by rotating the transmission gear 12. After the angle adjustment of the transmission gear 12 is completed, the rotating clamp 20 can be rotated around the fixed axis 19. The rotating clamp 20 is engaged with the transmission gear 12 to fix the transmission gear 12 after the angle adjustment. The cooperation of the two rotating clamps 20 can ensure that the transmission gear 12 cannot rotate clockwise and counterclockwise. The excess raw material liquid scraped off by the scraper 17 stays along the edge of the light guide plate body 4, falls on the side guide plate 21, and continues to flow and falls on the guide groove 22, and is discharged through the confluence groove 23 and the drain pipe 24.

[0049] Step 3: The light guide plate body 4 continues to move to the corresponding position below the dryer 45. According to the drying requirements, the lifting height and drying angle of the dryer 45 are adjusted. The lifting height of the dryer 45 is adjusted by lifting and lowering the lifting ring 42 and the U-shaped height adjustment frame 43 on the positioning column 41, and the raised part of the elastic clamping plate 44 is engaged with the positioning column 41 to achieve the adjusted fixation of the lifting ring 42 and the U-shaped height adjustment frame 43. By stretching the two height adjustment ropes 46 on one side, the height adjustment ropes 46 apply tension to the dryer 45, so as to lift one side of the dryer 45, and the rope buckle 47 is moved and fixed on the height adjustment rope 46 to achieve the fixation of the dryer 45 after the angle is adjusted.
