[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen processing device. Background Art

[0002] Liquid crystal display is a type of flat panel display. It is used for TV and computer screen display. The advantages of this display are low power consumption, small size and low radiation. Liquid crystal display uses a liquid crystal solution in two polarized materials. When current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging.

[0003] In the prior art, in order to avoid displacement of the LCD screen during processing of the LCD screen, the LCD screen is manually pressed or clamped and fixed by a corresponding clamp structure. Since manual pressing has a poor fixing effect on the LCD screen and affects the processing operation of the LCD screen, a clamp is generally used to clamp and fix the LCD screen. However, when the LCD screen is clamped and fixed by the clamp, the corresponding clamp can only clamp and fix LCD screens of the same size. When it is necessary to clamp and fix LCD screens of different sizes, the corresponding clamp needs to be replaced. Although some clamps can also clamp and fix LCD screens of different sizes, it takes time to adjust when clamping LCD screens of different sizes, and the operation is cumbersome, thereby reducing the processing efficiency of the LCD screen. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a liquid crystal display processing device, the clamping block of which can adaptively adjust the position according to the size of the liquid crystal display to achieve stable clamping and complete various processing tasks.

[0005] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the utility model, a liquid crystal display processing device is proposed, including a turntable, a clamping mechanism and a rotating mechanism; a cross slot is opened on the turntable, and the clamping mechanism is arranged at the four ends of the cross slot; the clamping mechanism includes a clamping block, a connecting column, a baffle and a positioning seat; the connecting column is arranged on the side wall of the clamping block; the baffle is fixedly connected to the side wall of the end of the cross slot; the positioning seat is arranged on the side wall of the baffle; and a spring is arranged inside the positioning seat; one end of the spring is connected to the inside of the positioning seat, and the other end is connected to the connecting column; the clamping block is slidably arranged in the cross slot, and a liquid crystal display is placed between the clamping blocks at the four ends of the cross slot; the rotating mechanism is arranged at the bottom of the turntable to drive the rotation.

[0006] As a further solution of the utility model: the rotating mechanism includes a support disk and a power device; the support disk is arranged at the bottom of the turntable; the power device is arranged at the bottom of the support disk, and the output end of the power device is connected to the turntable, and a plurality of balls are arranged in a ring on the top of the support disk; an annular groove is arranged at the bottom of the turntable, and the balls are rotatably arranged in the annular groove.

[0007] As a further solution of the utility model: the side wall of the clamping block is provided with a support plate, the liquid crystal display screen is arranged on the support plate, and the height of the support plate is higher than the top of the turntable.

[0008] As a further solution of the utility model: sliding blocks are arranged on both sides of the clamping block; sliding grooves are opened on the side walls on both sides of the cross groove, and the size of the sliding blocks is adapted to the sliding grooves.

[0009] As a further solution of the utility model: a limiting mechanism is also provided on the clamping mechanism; the limiting mechanism includes a guide column and a positioning bolt; one end of the guide column is connected to the side wall of the clamping block, and the other end extends toward the baffle and passes through the baffle; the positioning bolt is arranged on the top of the baffle to position the guide column.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model connects the spring and the connecting column so that the clamping block can slide flexibly in the cross groove.

This helps to improve the processing accuracy and ensure the processing quality.

[0014] 4. The utility model can realize the positioning of the guide column by adjusting the position of the positioning bolt on the top of the baffle, thereby accurately controlling the moving range of the clamping block in the cross slot.

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, a liquid crystal display processing device includes a turntable 1, a clamping mechanism and a rotating mechanism; a cross slot 11 is provided on the turntable 1, and the clamping mechanism is arranged at the four ends of the cross slot 11; the clamping mechanism includes a clamping block 2, a connecting column 21, a baffle 3 and a positioning seat 31; the connecting column 21 is arranged on the side wall of the clamping block 2; the baffle 3 is fixedly connected to the side wall of the end of the cross slot 11; the positioning seat 31 is arranged on the side wall of the baffle 3; and a spring 32 is arranged inside the positioning seat 31; one end of the spring 32 is connected to the inside of the positioning seat 31, and the other end is connected to the connecting column 21; the clamping block 2 is slidably arranged in the cross slot 11, and a liquid crystal display 8 is placed between the clamping blocks 2 at the four ends of the cross slot 11; the rotating mechanism is arranged at the bottom of the turntable 1 to drive the rotation.

[0022] The connection between the spring 32 and the connecting column 21 enables the clamping block 2 to slide flexibly in the cross slot 11. When the LCD screen 8 is placed between the four clamping blocks 2, the clamping blocks 2 can adjust their positions according to the size of the screen to achieve stable clamping.

[0023] like Figure 1 and Figure 4As shown, the rotating mechanism includes a support disk 4 and a power device 5; the support disk 4 is arranged at the bottom of the turntable 1; the power device 5 is arranged at the bottom of the support disk 4, and the output end of the power device 5 is connected to the turntable 1, and a plurality of balls 41 are arranged in a ring on the top of the support disk 4; an annular groove 12 is arranged at the bottom of the turntable 1, and the ball 41 is rotatably arranged in the annular groove 12.

[0024] The turntable 1 can rotate smoothly through the cooperation of the support plate 4 and the power device 5. The ball bearing 41 on the top of the support plate 4 matches the annular groove 12 at the bottom of the turntable 1, so that the turntable 1 has less friction resistance when rotating, runs more smoothly, and improves the working efficiency of the entire processing device.

[0025] like Figure 1 and Figure 2 As shown, a support plate 22 is provided on the side wall of the clamping block 2 , and the liquid crystal display screen 8 is provided on the support plate 22 . The height of the support plate 22 is higher than the top of the turntable 1 .

[0026] The support plate 22 is provided so that the LCD screen 8 can maintain a stable horizontal position during the processing. Since the height of the support plate 22 is higher than the top of the turntable 1, the display screen will not directly contact the turntable 1 when placed, thus avoiding the displacement or tilt of the display screen caused by the unevenness or vibration of the turntable 1. This helps to improve the processing accuracy and ensure the processing quality.

[0027] like Figure 2 and Figure 3 As shown, sliders 23 are provided on both sides of the clamping block 2 ; slide grooves 13 are provided on the side walls of both sides of the cross groove 11 , and the size of the sliders 23 is adapted to the slide grooves 13 .

[0028] Through the cooperation between the slider 23 and the slide slot 13, the movement of the clamping block 2 in the cross slot 11 is more stable. The design of the slider 23 limits the movement direction of the clamping block 2, so that it can only slide along the direction of the slide slot 13, avoiding deviation or shaking during processing.

[0029] like Figure 2 As shown, a limiting mechanism is also provided on the clamping mechanism; the limiting mechanism includes a guide column 6 and a positioning bolt 7; one end of the guide column 6 is connected to the side wall of the clamping block 2, and the other end extends toward the baffle 3 and passes through the baffle 3; the positioning bolt 7 is arranged on the top of the baffle 3 to position the guide column 6.

[0030] By adjusting the position of the positioning bolt 7 on the top of the baffle 3, the guide column 6 can be positioned, thereby accurately controlling the moving range of the clamping block 2 in the cross groove 11. This precise control helps to ensure that the LCD screen 8 is firmly clamped in a suitable position, avoiding problems such as damage to the screen or poor processing due to clamping too tight or too loose.

[0031] The working principle of the utility model is as follows: First, the operator places the LCD screen 8 on the support plate 22 between the four clamping blocks 2 on the turntable 1. Since the side walls of the clamping blocks 2 are provided with connecting columns 21, these connecting columns 21 are connected to the springs 32 in the positioning seat 31, so that the clamping blocks 2 can slide flexibly in the cross groove 11. At the same time, the sliders 23 on both sides of the clamping blocks 2 are adapted to the slide grooves 13 on the side walls of the cross groove 11, so that the clamping blocks 2 are more stable during the movement and avoid deviation or shaking. When the display screen is placed, the clamping blocks 2 will adjust their positions adaptively according to the size of the display screen, and through the elastic action of the springs 32, ensure that the display screen is firmly clamped between the four clamping blocks 2. Then turn the positioning bolts 7, so that the positioning bolts 7 position the guide columns 6 to limit the position of the clamping blocks 2. Next, start the power device 5 of the rotating mechanism. The output end of the power device 5 is connected to the turntable 1 to drive the turntable 1 to rotate. The power device 5 is preferably a rotary motor; when the turntable 1 rotates, the ball bearing 41 on the top of the support plate 4 matches the annular groove 12 at the bottom of the turntable 1, so that the friction resistance of the turntable 1 is small when rotating, and the operation is smoother. At the same time, during the processing, since the height of the support plate 22 is higher than the top of the turntable 1, the display screen can maintain a stable horizontal position, avoiding the displacement or tilt of the display screen caused by the unevenness or vibration of the turntable 1.

[0032] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
