DETAILED DESCRIPTION

[0025] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of protecting the edge of the liquid crystal screen of the present application is:

[0026] A display processing device, comprising two side clamping beams 01 with side rods 02 formed at both ends, and two rotating shafts 07 with threads in opposite directions on the upper and lower sides, each side rod 02 is provided with a side arm 06, and the two side arms 06 on the same side of the left and right are respectively connected to the upper and lower sides of the same rotating shaft 07 through threaded holes, and the two rotating shafts 07 are respectively rotatably connected to two side frames 08, and the two side clamping beams 01 are mirror-imaged up and down; when polishing a liquid crystal screen, the traditional method is to directly cut and then simply grind, but when the grinding device contacts the edge of the liquid crystal screen, it is easy to shake due to the friction between the contact and the friction, thereby causing the liquid crystal to be unstable. The edge of the screen is damaged, so in the present application, the edge of the LCD screen can be inserted between the two clamping beams 01, and then the two side arms 06 on the upper and lower sides of the rotating shaft 07 are moved closer to each other by rotating the rotating shaft 07, so that the side arms 06 drive the side rods 02 to move the clamping beams 01, so that the two clamping beams 01 clamp the edge of the LCD screen, and then the edge of the LCD screen is exposed from the rear ends of the two clamping beams 01, and the exposed part is the worn part that needs to be polished and ground. The LCD screen is clamped by the two clamping beams 01, so as to prevent the LCD screen from shaking during polishing, keep the edge of the LCD screen stable, and avoid the damage of the LCD screen due to shaking and the uneven polishing.

[0027] The front end of the clamping beam 01 is formed with an arc edge 03 with an arc structure, which can prevent the LCD screen from being scratched when the edge of the LCD screen passes between the two clamping beams 01, and can also smoothly slide the edge of the LCD screen between the two clamping beams 01 after the edge of the LCD screen touches it;

[0028] The upper end of the rotating shaft 07 is fixedly connected to a sprocket 09, and the two sprockets 09 are driven by a chain. When one of the rotating shafts 07 is driven to rotate by a power source, the sprockets 09 and the chain can be used to achieve synchronous rotation of the two rotating shafts 07;

[0029] A spring is fixedly connected between the lower end of the side arm 06 and the upper end surface of the clamping beam 01. When the two clamping beams 01 clamp the LCD screen, the spring is used to make the side rod 02 slide on the side arm 06 to achieve buffering, which can avoid damage to the LCD screen caused by direct clamping and improve the protection capability of the LCD screen.

[0030] See attached Figures 1 to 9From the structure shown, it can be understood that an exemplary operation process of polishing the edge of the liquid crystal screen of the present application is:

[0031] The upper rear sides of the two side frames 08 are fixedly connected to an upper beam 10, and a screw rod A11 is rotatably connected to the upper beam 10, and a slide seat 12 is connected to the screw rod A11, and a telescopic rod 13 is fixedly connected to the lower end of the slide seat 12, and a hanging seat 14 is fixedly connected to the lower end of the telescopic rod 13, and a polishing disc 15 is rotatably connected to the front end of the hanging seat 14, and a motor A16 for driving the polishing disc 15 to rotate is fixedly connected to the rear end of the hanging seat 14; after the edge of the LCD screen is clamped, the polishing disc 15 can be driven to rotate by the motor A16, and then the telescopic rod 1 3 drives the hanging seat 14 to descend, so that the polishing disc 15 contacts the exposed edge of the LCD screen, and the edge of the LCD screen is polished by the rotation of the polishing disc 15. Finally, another power source is used to drive the screw rod A11 to rotate, and the screw rod A11 is used to drive the slide 12 to move on the upper beam 10, so that the polishing disc 15 can move in a direction parallel to the rear edge of the clamping beam 01, so that the edge of the LCD screen is polished neatly, and the burrs and sharp parts on the edge after cutting are polished.

[0032] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of the automatic feeding and unloading of the present application is:

[0033] The front end of the side frame 08 is fixedly connected to a side slide 17, and a moving frame 19 is slidably connected to the two side slides 17. The left and right sides inside the moving frame 19 are fixedly connected to a support platform 20, and a screw rod B18 is rotatably connected to one of the side slides 17, and one end of the moving frame 19 is connected to the screw rod B18 through a threaded hole; the LCD screen is placed on the support platform 20, and then the screw rod B18 is driven to rotate by a power source, so that the screw rod B18 drives the moving frame 19 to move back and forth on the two side slides 17, thereby driving the LCD screen mounted on the support platform 20 to move back and forth, so that the edge of the LCD screen located on the rear side is moved between the two clamping beams 01 or taken out from between the two clamping beams 01 after polishing is completed, thereby realizing the process and effect of automatic feeding and unloading.

[0034] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of clamping the LCD screen of the present application is:

[0035] The upper and lower ends of the movable frame 19 are fixedly connected with hydraulic cylinders 21, and the hydraulic rod at the inner end of the hydraulic cylinder 21 is fixedly connected with a square frame 22, and the inner ends of the two square frames 22 are provided with chucks 23; after the LCD screen is mounted on the support table 20, the two hydraulic cylinders 21 can be used to drive the two square frames 22 to approach each other, so that the two chucks 23 clamp the LCD screen, thereby avoiding the hidden danger of the LCD screen slipping and falling when loading and unloading.

[0036] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of adjusting the direction of the liquid crystal screen of the present application is:

[0037] The inner side of the square frame 22 is fixedly connected with a motor B24, and the chuck 23 is rotatably connected to the inner end of the square frame 22. The motor B24 drives the chuck 23 to rotate. After the edge of one side of the LCD screen is polished, the LCD screen can be moved out from between the two clamping beams 01. After the LCD screen is clamped by the two chucks 23, the chuck 23 is driven by the motor B24 to rotate, so that the clamped LCD screen rotates in the direction to move the polished edge away, and the edge of the LCD screen to be polished is moved to align with the direction of the two clamping beams 01, thereby completing the direction adjustment of the LCD screen, so as to automatically complete the polishing of all edges of the LCD screen.

[0038] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of lowering the temperature of the present application is:

[0039] An inner cavity 04 is formed inside the clamping beam 01, and a plurality of leakage holes 05 are formed on the rear end surface of the clamping beam 01 on the upper side, and the plurality of leakage holes 05 are all connected with the inner cavity 04; when cooling water is introduced into the inner cavity 04, the cooling water can flow out from the plurality of leakage holes 05, so that the cooling water flows to the polishing disk 15 and the edge of the LCD screen, thereby reducing the temperature and avoiding safety hazards caused by temperature increase due to friction.

[0041] Step 1: Clamp the edge of the LCD screen between two clamping beams 01, and drive the polishing plate 15 to rotate through the motor A16;

[0042] Step 2: Make the rotating polishing disc 15 contact the edge of the liquid crystal screen at the rear end surface of the two clamping beams 01 leaking out from the rear side for polishing;

[0043] Step 3: The coolant leaks out through the multiple leak holes 05 to the contact position between the polishing plate 15 and the LCD screen;

[0044] Step 4: After processing one side, the LCD screen is clamped by two chucks 23 and rotated to move the other side to the polishing position.
