Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display manufacturing, and in particular to a liquid crystal display testing device. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display. Their advantages include low power consumption, small size, and low radiation. LCDs use a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve image formation. LCDs are flat, thin display devices composed of a certain number of color or monochrome pixels. They are placed in front of a light source or reflector, have low power consumption, and are suitable for battery-powered electronic devices.

[0003] In the existing technology, during the production process of the display screen, a testing device is needed to test the screen of the LCD display. When the display screen is tested for quality, it needs to be placed under the detector manually and then fixed manually. The testing process requires repeated manual operation, which results in a large workload and low work efficiency for workers. Therefore, an LCD display testing device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a liquid crystal display screen testing device, which aims to improve the problem in the prior art that "the display screen needs to be manually placed under the detector and then fixed during testing, and the testing process requires repeated manual operation, resulting in a large workload and low work efficiency for workers".

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a liquid crystal display screen testing device, comprising a housing 1 for mounting other components, a detector 5 for testing the display screen fixedly connected to the inner wall of the housing 1, a fixing assembly for fixing the display screen below the detector 5 provided inside the housing 1, the fixing assembly including a pressing plate 4 for fixing the display screen, a support plate 6 for supporting the pressing plate 4 fixedly connected to the right end of the pressing plate 4, a connecting plate 10 for connecting the support plate 6 and a moving block 11 fixedly connected to the bottom of the support plate 6, a moving block 11 for driving the connecting plate 10 to move fixedly connected to the upper surface of the connecting plate 10, a bidirectional lead screw 13 for driving other components to move provided on the inner wall of the moving block 11, a connecting rod 12 for supporting and pushing other components hinged to the outer wall of the moving block 11, and a fixing plate 7 for fixing the device inside the housing 1 hinged to the bottom of the connecting rod 12.

[0030] Reference Figure 1 , Figure 3 The housing 1 is equipped with a conveyor belt 2 for transporting the display screen to the extrusion plate 4. The outer wall of the conveyor belt 2 is equipped with a pusher block 3 for pushing the display screen. The inner wall of the housing 1 is fixedly connected with a baffle 8 for blocking the display screen to prevent it from moving too far. The baffle 8 is attached to the rear surface of the extrusion plate 4 and remains unchanged when the extrusion plate 4 moves. The front surface of the extrusion plate 4 is fixedly connected with a shovel block 17 for scooping up the display screen to facilitate its entry into the extrusion plate 4. The inner wall of the extrusion plate 4 is fixedly connected with an elastic pad 9 for providing cushioning for the extrusion and fixing of the extrusion plate 4.

[0031] Reference Figure 2 , Figure 3The outer wall of the bidirectional lead screw 13 is rotatably connected to a mounting plate 14 for mounting a motor 16. The motor 16 is mounted on the left surface of the mounting plate 14. The motor 16 provides power for the rotation of the bidirectional lead screw 13. The output shaft of the motor 16 is connected to the bidirectional lead screw 13 via a transmission belt 15. The transmission belt 15 transmits the power of the motor 16 to the bidirectional lead screw 13. The mounting plate 14 is slidably connected to the outer wall of the connecting plate 10, which can fix the mounting plate 14 to prevent rotation. The extrusion plate 4 is L-shaped, which can press and fix the two sides of the display screen when lifting the display screen. The front surface of the shovel block 17 is provided with an inclined surface, which can shovel the display screen and move it into the extrusion plate 4. The push block 3 is triangular in shape, so it will not contact the extrusion plate 4 when it is extruded and contracted.

[0032] Working principle: During use, the operator places the display screen on the conveyor belt 2, and the pusher block 3 on the outer wall of the conveyor belt 2 pushes the display screen towards the fixed component. During the pushing process, one end of the display screen is pushed, and the other end is lifted by the shovel block 17, so that the display screen enters above the extrusion plate 4. The motor 16 is started, and the motor 16 drives the bidirectional lead screw 13 to rotate through the transmission belt 15. When the bidirectional lead screw 13 rotates, it drives the moving block 11 to move inward. When the moving block 11 moves inward, it drives the connecting rod 12. The pushed connecting rod 12 moves it upward. At this time, the moving block 11 moves upward and inward. The moving block 11 drives the connecting plate 10, the connecting plate 10 drives the support plate 6, and the support plate 6 drives the extrusion plate 4 to move. When the extrusion plate 4 moves upward, it clamps the two sides of the display screen. At this time, the gap between the two extrusion plates 4 allows the pusher block 3 to pass through. When the extrusion plate 4 is not clamped, the position of the display screen can be adjusted by the pusher block 3. After the screen is fixed, it is detected by the detector 5. Then the extrusion plate 4 lowers the display screen and the pusher block 3 pushes it away to detect the next display screen. This reduces manual operation and improves detection efficiency.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
