[0002] Liquid crystal display (LCD) is an electronic display screen that uses liquid crystal materials and backlight to display images. It is widely used in various devices, such as TVs, computer monitors, smart phones, tablets, and dashboards. In the production process of LCD screens, edge grinding is a common process. Depending on the production process and product requirements, its main function is to remove the burrs and sharp corners of the LCD screen and improve the aesthetics.

[0003] Existing single-sided grinding devices can be divided into handheld, fixed, portable, fully automatic and semi-automatic types according to their structural design and operation methods. Among them, the handheld single-sided grinding device mainly relies on the worker's experience to grasp the grinding position and route when in use. However, when the worker holds the grinding device for a long time and performs grinding, hand shaking is inevitable, which causes the grinding position and route of the grinding device to shift, and results in poor grinding quality of the LCD screen by the grinding device.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0035] Example 1

[0036] A single-side grinding device for grinding the edge of a liquid crystal display screen, such as Figure 1-Figure 5 As shown, it includes an organism 11, a grinding block 12, a mounting frame 13, a clamping assembly, a rotating frame 14, a clamping ring 15, a clamping column 16, a bidirectional screw 17, a limit frame 18 and a pulley 19. The grinding block 12 is rotatably connected to the right side of the body 11, and the grinding block 12 is used for single-sided grinding of the liquid crystal display screen 1. The mounting frame 13 is clamped to the upper front part of the body 11 through the clamping assembly. The upper and lower parts of the front side of the mounting frame 13 are fixedly connected with clamping rings 15. The rotating frame 14 is slidably connected between the upper and lower clamping rings 15. The rotating frame 14 is slidably connected to the upper side of the rotating frame 14. The clamping column 16 is slidably connected to the clamping ring 15. The right side of the rotating frame 14 is rotatably connected to the bidirectional screw 17. The upper and lower parts of the right side of the rotating frame 14 are slidably connected to the limit frame 18. The limit frame 18 is threadedly connected to the bidirectional screw 17. The middle part of the right side of the rotating frame 14 is rotatably connected to the pulley 19, and the pulley 19 contacts and cooperates with the liquid crystal display screen 1.

[0037] like Figure 4 As shown, the clamping assembly includes a threaded rod 1301 and a first pressure block 1302. The threaded rod 1301 is threadedly connected to the front and rear sides of the mounting frame 13. The first pressure block 1302 is slidably connected to the front and rear sides of the mounting frame 13. The first pressure block 1302 is rotatably connected to the adjacent threaded rod 1301.

[0038] like Figure 3 and Figure 4 As shown, the middle of the clamp ring 15 is provided with small holes equidistantly distributed around the circumference for inserting the clamping columns 16 .

[0039] When the worker needs to grind the edge of the LCD screen 1, in order to ensure the stability of the grinding process, the mounting frame 13 can be first put on the upper part of the machine body 11, and then the threaded rod 1301 can be screwed forward. At this time, the threaded rods 1301 on the left and right sides will not only rotate forward, but also drive the first pressing blocks 1302 on the left and right sides to move toward each other, until the two first pressing blocks 1302 are both in close contact with the machine body 11, so that the mounting frame 13 and other components can be fixed on the machine body 11. After that, the grinding block 12 and the pulley 19 can be made to be in close contact with the edge of one side of the LCD screen 1, and then the two-way screw rod 17 can be rotated forward according to the thickness of the LCD screen 1, thereby driving the upper and lower limit frames 18 to move toward each other, until the limit frames 18 on both sides are in contact with the LCD screen 1, so that the horizontal height of the machine body 11 and the grinding block 12 can be limited by the limit frames 18 and the LCD screen 1, so as to avoid the machine body 11 and the grinding block 12 being in close contact with each other. During the grinding process, the worker's hands shake up and down, causing the grinding position to shift and affecting the grinding effect. Next, the clamping column 16 can be pulled out upward, and the body 11, the mounting frame 13, the clamping ring 15 and other components can be rotated according to the worker's holding habit until the body 11 and other components are adjusted to a suitable inclination angle, and then the clamping column 16 is inserted back into the original position to fix the inclination angle of the body 11 and other components. Finally, the grinding block 12 can start to rotate and grind the edge of the liquid crystal display screen 1. At the same time, the body 11 and the grinding block 12 and other components need to be moved along one side edge of the liquid crystal display screen 1 until the grinding is completed. After the grinding is completed, the bidirectional screw rod 17 is controlled to rotate in the opposite direction and drive the limit frames 18 on the upper and lower sides to move back and reset. The presence of the pulley 19 can reduce the friction between the liquid crystal display screen 1 and this single-sided grinding device, so that the movement of the body 11 and the grinding block 12 and other components is smoother.

[0040] Example 2

[0041] On the basis of Example 1, Figure 6-Figure 8 As shown, it also includes a guiding mechanism, which is arranged on the limiting frame 18. The guiding mechanism includes a moving frame 2, a telescopic rod 21, a mounting block 22, a second pressure block 23, a pressure frame 24 and a suction cup 25. The moving frame 2 is fixedly connected to the right side of the limiting frame 18. The right part of the moving frame 2 is slidably connected with the telescopic rod 21. The mounting blocks 22 are slidably connected to the front and rear sides of the outside of the telescopic rod 21. The side of the mounting block 22 away from the liquid crystal display screen 1 is slidably connected to the second pressure block 23, and the second pressure block 23 is pressed and matched with the adjacent telescopic rod 21. The side of the mounting block 22 away from the liquid crystal display screen 1 is rotatably connected to the pressure frame 24, and the pressure frame 24 is pressed and matched with the adjacent second pressure block 23. The side of the mounting block 22 close to the liquid crystal display screen 1 is fixedly connected with suction cups 25 symmetrically distributed on the left and right, and the suction cups 25 are in contact and matched with the liquid crystal display screen 1.

[0042] like Figure 7 and Figure 8As shown, the distance between the right side plane of the press frame 24 and its rotation axis is smaller than the distance between the bottom plane and its rotation axis.

[0043] When the worker needs to polish the edge of the LCD screen 1, he can also adjust the length of the telescopic rod 21 according to the length of the LCD screen 1, and ensure that the length of the telescopic rod 21 is slightly longer than the LCD screen 1, and then adjust the angles of the rotating frame 14 and the movable frame 2, and ensure that the telescopic rod 21 is parallel to the LCD screen 1, and then the pressing frame 24 can be rotated 90° upward and no longer squeeze the second pressing block 23, and the second pressing block 23 will no longer squeeze the telescopic rod 21. At this time, the worker can move the mounting blocks 22 and other components on the front and rear sides to the front and rear ends of the telescopic rod 21 respectively, and then rotate the pressing frame 24 90° to the left to reset. At this time, the pressing frame 24 will squeeze the second pressing block 23 and make it close to the adjacent telescopic rod 21, so that the mounting blocks 22 and other components can be fixed to the front and rear ends of the telescopic rod 21. When the bidirectional screw rod 17 rotates forward When the upper and lower limit frames 18 are driven to move toward each other, the suction cups 25 and other components on the upper and lower sides will also move toward each other with the limit frames 18 until the suction cups 25 on the upper and lower sides are in close contact with the LCD screen 1, so that the mounting block 22, the telescopic rod 21 and other components can be fixed on the LCD screen 1. When the body 11 and the grinding block 12 and other components move along one side edge of the LCD screen 1, the movable frame 2 will also move along the telescopic rod 21, so that the grinding route can be defined in advance with the help of the movable frame 2 and the telescopic rod 21 and other components, thereby avoiding the body 11 and the grinding block 12 and other components from being offset due to the worker's hand shaking and causing the grinding route to be offset. When the bidirectional screw rod 17 rotates in the opposite direction and drives the upper and lower limit frames 18 to move backwards and reset, the upper and lower movable frames 2 and the suction cups 25 and other components will also move backwards and reset.

[0044] like Fig. 9 and Fig.10 As shown, a leveling mechanism is also included, which is arranged on the limit frame 18. The leveling mechanism includes a connecting frame 3, a guide frame 31, a spring piece 32 and a top block 33. The four connecting frames 3 are respectively fixed to the front and rear sides of the upper and lower limit frames 18. The connecting frame 3 is slidably connected to the guide frame 31 on the outside, and a spring piece 32 is fixed between the connecting frame 3 and the guide frame 31. A top block 33 is fixed to the side of the guide frame 31 close to the liquid crystal display screen 1, and the top block 33 is squeezed and fitted with the liquid crystal display screen 1.

[0045] When the bidirectional screw rod 17 rotates forward and drives the upper and lower limit frames 18 to move toward each other, the upper and lower connecting frames 3, guide frames 31 and top blocks 33 will also move toward each other until the top blocks 33 contact the liquid crystal display screen 1. When the upper and lower connecting frames 3 continue to move toward each other, the guide frames 31 will slide relative to the adjacent connecting frames 3, and the spring sheets 32 will be deformed and compressed. At this time, the top blocks 33 and guide frames 31 on the upper and lower sides will squeeze the liquid crystal display screen 1 and straighten it under the elastic force of the spring sheets 32, so as to avoid uneven grinding due to the bending of the liquid crystal display screen 1. When the bidirectional screw rod 17 rotates reversely and drives the upper and lower limit frames 18 to move backward and reset, the upper and lower connecting frames 3, guide frames 31 and top blocks 33 will also move backward and reset, and the spring sheets 32 will be deformed and restored to their original state.

[0046] like Figure 11-13 As shown, a cleaning mechanism is also included, which is arranged on the mounting frame 13. The cleaning mechanism includes an elastic component 4, a mounting plate frame 41, a nozzle 42, a connecting pipe 43, a friction wheel 44, a rotating blade 45 and a filter screen 46. The elastic component 4 is fixedly connected to the front side of the mounting frame 13, and the telescopic end of the elastic component 4 is fixedly connected to the mounting plate frame 41. The friction wheel 44 is rotatably connected inside the mounting plate frame 41. The friction wheel 44 is in contact with the grinding block 12. The front side of the friction wheel 44 is fixedly connected with a rotating blade 45. The filter screen 46 is fixedly connected inside the mounting plate frame 41. The filter screen 46 is rotatably connected to the friction wheel 44. The nozzle 42 is fixedly connected to the right side of the mounting frame 13. The connecting pipe 43 is fixedly connected and communicated between the nozzle 42 and the mounting plate frame 41.

[0047] When the grinding block 12 starts to rotate and grinds the edge of the liquid crystal display screen 1, the friction wheel 44 will always keep close to the grinding block 12 under the action of the elastic component 4, and the rotation of the grinding block 12 will drive the friction wheel 44 to rotate through the friction force, and the rotation of the friction wheel 44 will also drive the rotating blade 45 to rotate and input the external air into the nozzle 42 through the connecting pipe 43, and the nozzle 42 will spray out the gas and blow off the debris generated by grinding, so that the debris generated by grinding can be blown off without power drive, avoiding the debris and other residues from affecting the quality of the liquid crystal display screen 1, and also preventing the debris from adhering to the grinding block 12, causing the grinding block 12 to wear faster and its service life to be rapidly shortened, wherein the presence of the filter 46 can prevent the debris from contacting the rotating blade 45 and interfering with its rotation.

[0048] like Figure 1 and Fig.14As shown, a protective mechanism is also included, which is arranged on the rotating frame 14. The protective mechanism includes a fixed frame 5, a winding box 51, a clamping frame 52 and an elastic pressure block 53. The two fixed frames 5 are respectively fixed to the upper and lower parts of the front side of the rotating frame 14. A winding box 51 is fixed between the front ends of the two fixed frames 5. A protective film is wound inside the winding box 51. A clamping frame 52 is fixed to the front side of the winding box 51. An elastic pressure block 53 is fixed to the front side of the clamping frame 52. The elastic pressure block 53 is squeezed and matched with the protective film.

[0049] Before grinding the edge of the LCD screen 1 with the grinding block 12, the worker can also lead out one end of the protective film in the winding box 51 and stick one end of the protective film to the corner of the left front side of the LCD screen 1. When the grinding block 12 and other components grind the LCD screen 1 and move backward, the winding box 51 also moves backward, and the protective film in the winding box 51 is gradually drawn out and covers the edge of the polished LCD screen 1. During this period, the elastic pressing block 53 will always remain in a deformed state under the squeezing of the LCD screen 1, and the elastic pressing block 53 in the deformed state will resist the protective film and make the protective film close to the edge of the LCD screen 1, so that a layer of protective film can be wrapped around the polished LCD screen 1, thereby preventing the LCD screen 1 from being polluted and affected by the external environment.

[0050] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
