The bearing mechanism 4 includes a lifting platform 9, a horizontal frame 10, and multiple panel supports 12. The lifting platform 9 is slidably mounted on the two slide rails 35, and is connected to the lead screw 37 via a lead screw nut. The horizontal frame 10 is horizontally mounted on the lifting platform 9, and the multiple panel supports 12 are matrix-mounted on the horizontal frame 10. The multiple panel supports 12 are used to load LCD panels. It also includes multiple ball seats 11, multiple ball heads 13, multiple connecting plates 14, push rods 15, and two slide blocks 16. 6. Push cylinder 17, movable plate 18, and two push cylinders 19, and multiple ball seats 11 are evenly installed on the horizontal frame 10. The lower end faces of multiple panel supports 12 are each mounted with ball heads 13 via support rods. The multiple ball heads 13 are movably installed in the multiple ball seats 11. Multiple connecting plates 14 are movably connected to the multiple support rods via ball head bearings. Push rod 15 is connected to the multiple connecting plates 14. The multiple connecting plates 14 are arranged in parallel, and the push rod 15 and the multiple connecting plates 14 are arranged perpendicularly.

[0038] Example 3

[0039] like Figure 8 and Figure 9As shown, the lifting mechanism 25 includes a gantry 22 and a push cylinder 3 23. The gantry 22 is mounted on the lifting platform 9, and the fixed end of the push cylinder 3 23 is mounted on the gantry 22. The lower end of the piston rod of the push cylinder 3 23 is connected to the spray pipe assembly 6 and the jet mechanism 7. The jet mechanism 7 includes a crossbeam 24 and multiple adjustable angle nozzles. The adjustable angle nozzles include a motor 1 26, a motor frame 27, a motor 28, and a jet nozzle 29. The multiple adjustable angle nozzles are respectively mounted on the crossbeam 24 and are located above multiple panel supports 12. The motor 1 26 is mounted on the crossbeam 24 through a bracket. The output shaft of the motor 1 26 is connected to the motor frame 27. The motor 28 is mounted on the motor frame 27. The jet nozzle 29 is mounted on the output shaft of the motor 28. The output shaft of the motor 1 26 is perpendicular to the output shaft of the motor 28. The jet nozzle 29 is located at the intersection of the extension line of the output shaft of the motor 1 26 and the extension line of the output shaft of the motor 28.

[0040] The gantry 22 rises and falls together with the lifting platform 9. The gantry 22 supports the push cylinder 3 23, which drives the spray pipe assembly 6 and the air jet mechanism 7 to rise and fall. The distance between the spray pipe assembly 6 and the air jet mechanism 7 and the bearing mechanism 4 is adjusted to facilitate the loading and unloading of the LCD panel. Multiple air jet nozzles 29 are connected to the high-pressure air system. The high-pressure air system adjusts the air jet pressure and air jet time of the multiple air jet nozzles 29. Motor 1 26 drives the motor frame 27 to rotate, and Motor 2 28 drives the air jet nozzles 29 to rotate, thereby automatically adjusting the spray angle of the air jet nozzles 29, which is practical.

[0041] like Figure 8 As shown, it also includes multiple irregularly shaped nozzles 25, which are mounted on the crossbeam 24 and located above multiple panel supports 12. The irregularly shaped nozzles 25 are rectangular rings and spray air towards the edge of the liquid crystal panel.

[0042] By setting multiple irregularly shaped nozzles 25 to spray air onto the edge of the LCD panel, the etching solution at the edge of the LCD panel is drained, thereby focusing the etching on the center of the LCD panel, thus etching out an LCD panel with a groove shape that matches the curved screen.

[0043] like Figure 1As shown in Figure 10, the liquid crystal panel etching and thinning processing equipment of the present invention, during operation, first loads multiple liquid crystal panels onto multiple panel holders 12. The measuring mechanism 8 detects the overall thickness and flatness of the etched surface of the multiple liquid crystal panels and identifies relatively low-lying areas on the etched surface of the multiple liquid crystal panels. Then, the push cylinder 3 23 extends to drive the spray pipe assembly 6 and the air jet mechanism 7 to descend closer to the bearing mechanism 4 to the working distance. The motors 1 26 and 2 28 coordinate with the angle of the multiple air jet nozzles 29 so that the air jet nozzles 29 are respectively directed toward the aforementioned low-lying areas. The servo motor 38 drives the lead screw 37 to rotate and drive the lifting platform 9 to descend, so that the multiple panel holders 12 extend into the etching pool 2. Then, the air jet mechanism 7 and the spray pipe assembly 6 are activated, and the etching liquid sprayed from the spray pipe assembly 6 sprays from top to bottom onto the liquid crystal panels. The airflow sprayed from the multiple air jet nozzles 29 will... The etching solution in the low-lying areas is drained. The area of ​​the undrained etching solution is adjusted by adjusting the air pressure of multiple nozzles 29. The jetting time of multiple nozzles 29 can be set to be applicable to low-lying areas of different depths. The thickness and flatness are measured multiple times by the measuring mechanism 8 and the angle of multiple nozzles 29 is adjusted to achieve targeted etching and thinning of thicker local areas on the etching surface of the LCD panel. Finally, when it is necessary to etch rounded corners at the edges of the LCD panel, multiple adjustable-angle nozzles of the jetting mechanism 7 are directed vertically toward the center of the LCD panel to increase the jetting pressure and drain all the etching solution on the etching surface of the LCD panel. This allows the etching solution to gather at the edge of the hydraulic panel, thus achieving the etching of rounded corners at the edges of the LCD panel. Alternatively, the push cylinder 17 and push cylinder 2 19 can be extended and retracted to drive multiple panel supports 12 to tilt and swing back and forth and left and right, so that the etching solution can etch rounded corners at the edges of the LCD panel.

[0044] The main functions achieved by this invention are:

[0045] 1. It can perform targeted etching to thin out thicker areas of the LCD panel, thereby improving the overall flatness of the LCD panel;

[0046] 2. Capable of etching the rounded corners of LCD panels;

[0047] 3. It can employ both top spraying and immersion etching methods;

[0048] 4. It can etch grooves in the center of the LCD panel, making it suitable for curved screens.
