Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal displays, in particular to a display screen substrate spacing control component. Background Art

[0002] STN-LCD, that is, super twisted nematic liquid crystal display, liquid crystal display is based on liquid crystal materials. Compared with TN-type liquid crystal display, STN-type liquid crystal display has display advantages such as wide viewing angle, high contrast, and high duty cycle. High duty cycle may also bring some problems, one of which is the "tailing" phenomenon. Tailing usually refers to the situation that when displaying dynamic images, the pixel response speed is not fast enough, resulting in the image leaving a tail-shaped afterimage when moving, which will affect the display clarity and dynamic expression.

[0003] Since the existing STN-type liquid crystal displays do not optimize the empty box thickness of each display glass substrate in the liquid crystal display screen, it is impossible to break through the display limit of the STN-type liquid crystal display. In addition, the difference in empty box thickness between different glass substrates may lead to uneven display quality, such as differences in brightness, color, contrast, etc., which in turn affects the display clarity and dynamic expression. The practicality needs to be improved. Utility Model Content

[0025] Example

[0026] like Figure 1-Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a display screen substrate spacing control component, including a base 11 and a hanging plate 12, the hanging plate 12 is located above the base 11, a pushing unit 13 is fixedly installed on the upper end of the hanging plate 12, an injection unit 14 is fixedly installed on the output shaft of the pushing unit 13, the injection unit 14 is located between the base 11 and the hanging plate 12, a controller 15 is fixedly installed on the surface of the base 11, mechanical arms 16 are symmetrically fixedly installed on the side walls of the base 11, suction cup units 17 are fixedly installed at the output shafts of the two mechanical arms 16, polarizers 18 are sucked on the side walls of the two suction cup units 17, and a slide groove 19 is opened inside the base 11;

[0028] A spacing adjustment mechanism is fixedly mounted on the side wall of the base 11;

[0029] The adjustment mechanism includes a motor 21, and a micron-level bidirectional screw 22 is fixedly installed on the output shaft of the motor 21. The micron-level bidirectional screw 22 is rotatably installed inside the slide groove 19. The adjustment mechanism also includes a transmission block 23, a U-shaped clamp 24, a side groove 28, a slider 29 and a micron-level distance sensor 31. The two transmission blocks 23 are threadedly installed on the circumferential surface of the micron-level bidirectional screw 22. By setting the mechanical arm 16 and the suction cup unit 17, the glass body 27 can be bonded to the polarizer 18 after the glass assembly is processed, thereby improving the glass assembly. The processing efficiency is improved, and the practicality is improved. The device can also control the distance between the two substrate bodies 26 by changing the thickness of the spacer between the substrate bodies 26. Since there is a baffle between the two slide grooves 19, the distance between the two substrate bodies 26 can be forced to be controlled by the thickness between the spacers at the opposite ends of the two substrate bodies 26, thereby controlling the thickness of the empty box remaining between the glass assemblies, breaking through the display limit of the liquid crystal display, reducing the impact on the clarity and dynamic expression of the liquid crystal display, and improving practicality.

[0030] The two transmission blocks 23 are both slidably installed with the slide groove 19, and the upper ends of the two transmission blocks 23 are fixedly installed with U-shaped clamps 24. The inner sides of the two U-shaped clamps 24 are symmetrically provided with clamping plates 25. A glass assembly is clamped between each set of clamping plates 25. The glass assembly includes a substrate body 26 and a glass body 27. A gasket is provided on the side wall of each substrate body 26. Each substrate body 26 is located on the inner side of the glass body 27. By turning on the motor 21, the motor 21 drives the micron-level bidirectional screw 22 (the micron-level bidirectional screw 22 is a precision transmission device, which is usually used in mechanical systems that require small displacements and high-precision control, and can achieve synchronous movement and control in two directions. Due to the micron-level bidirectional screw 22, the micron-level bidirectional screw 22 can be driven by the motor 21. The design and manufacturing precision of the two-way screw rod 22 is very high, so it can achieve micron-level displacement control and is widely used in precision instruments, mechanical processing equipment and automation systems to meet application scenarios with high requirements for accuracy and stability) rotation, so that the micron-level two-way screw rod 22 and the transmission block 23 are threadedly transmitted, so that the two transmission blocks 23 move in the direction of approaching each other inside the slide groove 19. At the same time, the movement of the transmission block 23 will drive the U-shaped clamp 24 and the slider 29 to move, and then the thickness of the empty box remaining between the glass assemblies can be controlled, thereby breaking through the display limit of the LCD display, reducing the impact on the clarity and dynamic expression of the LCD display, and improving practicality.

[0031] Both side grooves 28 are opened inside the base 11, and both side grooves 28 are located on both sides of the slide groove 19. Each slider 29 is slidably installed inside the side groove 28. Each slider 29 is fixedly installed with the U-shaped clamp 24. The micron-level distance sensor 31 is fixedly installed on the side wall of the slider 29. When the motor 21 drives the micron-level bidirectional screw 22 to rotate, the two transmission blocks 23 move in the direction of approaching each other inside the slide groove 19. At the same time, the movement of the transmission block 23 will drive the U-shaped clamp 24 and the slider 29 to slide in the side groove 28, thereby providing multi-party limit to increase stability.

[0032] Working principle:

[0033] The first step is that when using, the staff can first use the hanger to move the glass assembly to the inside of the U-shaped clamp 24, and then the staff can turn on the motor on the U-shaped clamp 24, so that the U-shaped clamp 24 drives the clamping plate 25 to clamp the glass body 27 glass assembly, and then the staff can repeat the above steps to complete the clamping of another glass assembly, and then the staff can turn on the motor 21, so that the motor 21 drives the micron-level bidirectional screw 22 to rotate, so that the micron-level bidirectional screw 22 and the transmission block 23 are threadedly transmitted, so that the two transmission blocks 23 move in the direction of approaching each other inside the slide groove 19, and at the same time, the movement of the transmission block 23 will drive the U-shaped clamp 24 and the slider 29 to move;

[0034] In the second step, when the micron-level distance sensor 31 in the side groove 28 detects that the distance between the sliders 29 on the other side reaches the process requirement, the micron-level distance sensor 31 will send a signal to the controller 15, so that the controller 15 disconnects the motor 21, and then the staff can turn on the pushing unit 13 on the hanging plate 12, so that the pushing unit 13 pushes the injection unit 14 (the injection unit 14 adopts a spraying density of 120 particles / square millimeter, the alignment layer film thickness is adjusted to 350-400 angstroms, and the pressing amount can reach 500ANG) to reduce the pre-tilt angle by 4-5° and open the conveying unit to convey the liquid crystal spacer material to the spacer between the two substrate bodies 26 for coating (the material is Enhanced optical properties of the material), when the coating is completed, the pushing unit 13 will drive the injection unit 14 (the injection unit 14 is a prior art, generally composed of a valve, a pipe, a shell, an angle motor, a bearing, etc.) to reset, and the material conveying unit will disconnect the material supply in the injection unit 14 (the feed port of the injection unit 14 is connected to the discharge port of the external material conveying unit by a pipe). At this time, after the material conveying is completed, the controller 15 will control the robot arm 16 to move, so that the robot arm 16 controls the suction cup unit 17 to attach the polarizer 18 to the surface of the glass body 27, and then the base 11 can be reset on the external slide rail and the processed glass assembly can be taken out again using the sling to complete the processing.

[0035] The third step is to control the spacing between the two substrate bodies 26 by changing the thickness of the spacer between the substrate bodies 26 (the spacer material is a silicon ball material with a length of 5 μm, the material is coated between the spacers, the orientation layer is PI: DL3690, and the injection unit 14 needs to be pre-tilted by 4-5° before coating). Since there is a baffle between the two slide grooves 19, the spacing between the two substrate bodies 26 can be forced to be controlled by the thickness between the spacers at the opposite ends of the two substrate bodies 26, thereby controlling the thickness of the empty box remaining between the glass assemblies, breaking through the display limit of the liquid crystal display, reducing the impact on the clarity and dynamic expression of the liquid crystal display, and improving practicality.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
