DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 , a device for grinding vertical edges of anti-shattering ultra-thin special-shaped liquid crystal display glass, comprising a workbench 1, a first inner cavity 2 is opened in the workbench 1, two side panels 3 are fixedly connected to the upper end of the workbench 1, and a top plate 4 is fixedly connected to the upper ends of the two side panels 3. A motor 5 is installed on the inner top of the first inner cavity 2, and the motor 5 is a servo motor that can change the rotation direction. The output shaft of the motor 5 is rotatably connected to the inner top of the first inner cavity 2. A support plate 6 is arranged on the upper end of the workbench 1, and the output shaft of the motor 5 passes through the inner top of the first inner cavity 2 and is fixedly connected to the lower end of the support plate 6. A bracket 16 is fixedly connected to the right side of the side panel 3 on the right side, and a grinder 17 is placed on the bracket 16. The grinder 17 is mainly composed of a shell, a motor, and a grinding head, and can grind the vertical edges of the liquid crystal display glass;

[0023] The pressing mechanism is also included, which is used to cooperate with the support plate 6 to fully press the liquid crystal display glass. The pressing mechanism includes a telescopic rod 7 installed on the upper end of the top plate 4. The telescopic rod 7 is an electric telescopic rod. The telescopic end of the telescopic rod 7 is rotatably connected to a lower pressing plate 8. The horizontal plane length and width of the support plate 6 and the lower pressing plate 8 are the same. The lower end of the lower pressing plate 8 is fixedly connected to a rubber pad 9, which can avoid excessive squeezing of the liquid crystal display glass.

[0024] Among them, it also includes a positioning component, which is used for pre-positioning the liquid crystal display glass and assisting the downward pressing mechanism to rotate in coordination. The positioning component includes a return-shaped limit frame 13 arranged at the upper end of the workbench 1, and the inner wall of the return-shaped limit frame 13 is slidably connected to the side wall of the support plate 6. A control button (not shown) for controlling the extension and retraction of the telescopic rod 7 is arranged on the right side of the return-shaped limit frame 13. The left and right sides of the return-shaped limit frame 13 are both horizontally provided with a first through groove 14, and the left and right sides of the return-shaped limit frame 13 are both fixedly connected with a handle 15;

[0025] Among them, the upper end of the lower pressure plate 8 is fixedly connected to two C-shaped connecting blocks 10, and the inner sides of the two C-shaped connecting blocks 10 are provided with L-shaped connecting blocks 11. Each L-shaped connecting block 11 is composed of a horizontal plate and a vertical plate. Each horizontal plate is slidably connected to the inner side of the corresponding C-shaped connecting block 10. The two L-shaped connecting blocks 11 are matched with the corresponding first through grooves 14. The horizontal plates on the two L-shaped connecting blocks 11 can be respectively passed through the corresponding first through grooves 14 to achieve support for the return-shaped limit frame 13. The lower end of each horizontal plate is fixedly connected with an anti-slip pad 12.

[0026] In the present invention, the horizontal plane lengths and widths of the support plate 6, the lower pressing plate 8 and the liquid crystal display glass to be polished are the same. When in use, the ultra-thin special-shaped liquid crystal display glass is first placed horizontally on the upper end of the support plate 6, and the return-shaped limit frame 13 is driven to move up a certain distance by holding the two handles 15, so that the inner wall of the return-shaped limit frame 13 surrounds the liquid crystal display glass, thereby completing the pre-positioning of the liquid crystal display glass, and then the telescopic rod 7 is controlled by the control button on the right side of the return-shaped limit frame 13 to drive the lower pressing plate 8 to move down. During the downward movement of the lower pressing plate 8, it will pass through the inner side of the return-shaped limit frame 13 and continue to move down until the rubber pad 9 completely presses the liquid crystal display glass, thus completing the comprehensive pressing of the liquid crystal display glass, which can effectively prevent the ultra-thin special-shaped liquid crystal display glass from vibrating and breaking during the polishing process;

[0027] After completing the clamping operation, the staff uses two thumbs to control the two L-shaped connecting blocks 11 to move back to each other, so that the horizontal plates on the two L-shaped connecting blocks 11 pass through the corresponding first through grooves 14, thereby supporting the return-type limit frame 13, starting the motor 5 to drive the support plate 6 to rotate, drive the return-type limit frame 13 to rotate, and drive the lower pressure plate 8 to rotate, so that the LCD display glass can be rotated while maintaining full compression. At this time, the staff can select a suitable grinding angle and turn off the motor 5, and then control the two L-shaped connecting blocks 11 to move toward each other to release the support for the return-type limit frame 13, so that the return-type limit frame 13 will move down to the upper end of the workbench 1 and expose the vertical edge of the LCD display glass. At this time, the staff can use the grinder 17 to grind the vertical edge of the LCD display glass. When it is necessary to grind the vertical edge of the LCD display glass at other angles, the LCD display glass can be rotated with reference to the above operation. In this way, through the cooperation of the motor 5 and the return-type limit frame 13, it is greatly convenient for the staff to grind the LCD display glass at multiple angles.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
