Abstract
Description
Technical Field
[0001] This utility model belongs to the field of performance testing of hot-pressing buffer materials for liquid crystal panels, and specifically relates to a device for testing the performance of hot-pressing buffer materials for liquid crystal panels. Background Technology
[0002] The LCD panel is the material that determines the brightness, contrast, color, and viewing angle of an LCD monitor. The price trend of the LCD panel directly affects the price of the LCD monitor. The quality and technology of the LCD panel are related to the overall performance of the LCD monitor. Whether an LCD panel can achieve 16.7M colors (true color display) means that it has the ability to physically display 256 levels of grayscale in each of the three RGB color channels. Production volume, quality, and market environment are all factors that affect the quality, price, and market trend of an LCD monitor, because about 80% of the cost of an LCD monitor is concentrated in the panel.
[0003] However, most existing tests on the hot-pressed buffer materials of LCD panels rely on manual tapping to assess their buffering capacity. This method fails to directly reveal the impact force and buffering performance of the material, thus reducing the accuracy of the test. Therefore, a device for testing the performance of hot-pressed buffer materials for LCD panels is proposed. Utility Model Content

Movable parts are threadedly connected to the outer surfaces of the movable screws. Clamping blocks are fixedly connected to the opposite sides of the movable parts. Detection blocks are sleeved on the outer surfaces of the clamping blocks. A mounting slot is provided at the lower end of the adjustment component.

[0008] As a preferred technical solution, the drive assembly includes a transmission wheel disposed on the upper end of the bracket, the outer surfaces of the transmission wheel being interconnected by a transmission belt, a drive motor being fixedly connected to the upper end of the bracket, the drive motor being fixedly connected to the transmission wheel, and the transmission wheel being fixedly connected to an adjusting screw through the bracket.
[0009] As a preferred technical solution, a movable handle is fixedly connected to the outer side of the bracket, and an anti-slip pad is fixedly connected to the outer surface of the movable handle. The movable handle is fixedly connected to the bracket by screws.
[0010] As a preferred technical solution, the fixing component includes a fixing plate disposed on the inner side of the bracket, a clamping plate slidably connected to the upper end of the fixing plate on the inner side of the bracket, mounting plates fixedly connected to both sides of the bracket, an electric push rod fixedly connected to the surface of the mounting plate, and the other end of the electric push rod fixedly connected to the clamping plate.
[0011] As a preferred technical solution, the inner side of the clamping plate is slidably connected to the inner side of the bracket, the inner side of the bracket is provided with sliding grooves, and the inner side of the clamping plate is fixedly connected with a sliding block, and the sliding groove and the sliding block are slidably connected to each other.

[0013] In summary, the present invention has the following main advantages:
[0014] First, this utility model, through its detection component, uses a fixed component to fix the hot-pressed buffer material. Then, the detection component is moved to a suitable position by the adjustment component. The detection motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, causing the moving screw to rotate. The rotation of the moving screw causes the moving part to move outward, thereby disengaging the clamping block from the detection block and causing the clamping block to fall downward, making the detection block contact the hot-pressed buffer material. This allows for an impact effect on the hot-pressed buffer material, enabling the observation of whether the hot-pressed buffer material is damaged and thus enabling the detection of the hot-pressed buffer material's performance.
[0015] Secondly, this utility model, through its fixed assembly, places the hot-pressed buffer material on the upper end of the fixed plate. The electric push rod moves, causing the clamping plate to move downwards, thus fixing the hot-pressed buffer material. This facilitates testing of the material and prevents displacement during testing. Furthermore, the adjustable assembly allows the screw to rotate, moving the threaded component. This movement of the threaded component moves the adjusting rod, enabling the movement of the testing assembly. This increases the impact force and allows for testing of the hot-pressed buffer material under different impact forces. Attached Figure Description

A bracket 2 is fixedly connected to the upper end of the plate 1. An adjustment component 3 is disposed inside the bracket 2. A driving component 4 is disposed at the upper end of the bracket 2. A fixing component 6 is disposed inside the bracket 2 at the lower end of the adjustment component 3. A detection component 5 is disposed at the lower end of the adjustment component 3. The detection component 5 includes movable grooves 51 disposed on both sides of the lower end of the adjustment component 3. Movable screws 52 are rotatably connected inside each movable groove 51. The outer surfaces of the movable screws 52 are threaded together. A movable component 53 is connected, and clamping blocks 54 are fixedly connected to the opposite sides of the movable component 53. A detection block 55 is sleeved on the outer surface of the clamping block 54. An installation groove 56 is opened at the lower end of the adjusting component 3. A driven bevel gear 57 is fixedly connected through the installation groove 56 by a movable screw 52. An active bevel gear 58 is rotatably connected inside the installation groove 56. The active bevel gear 58 and the driven bevel gear 57 are meshed with each other. A detection motor 59 is fixedly connected to the upper end of the adjusting component 3. The output shaft of the detection motor 59 is fixedly connected through the installation groove 56 to the active bevel gear 58.
[0023] refer to Figures 1-4 The adjustment assembly 3 includes an adjustment groove 31 located inside the support 2. An adjustment screw 32 is rotatably connected to the inside of each adjustment groove 31. A threaded component 33 is threaded onto the outer surface of the adjustment screw 32. An adjustment rod 34 is fixedly connected to the outer side of the threaded component 33. A fixed plate 35 is fixedly connected to the outer surface of the adjustment rod 34. The upper end of the fixed plate 35 is fixedly connected to the detection motor 59. A moving groove 51 is located at the lower end of the adjustment rod 34. The drive assembly 4 includes a transmission wheel 41 located at the upper end of the support 2. The outer surfaces of the transmission wheel 41 are connected to each other via a transmission belt 42. The transmission connection includes a drive motor 43 fixedly connected to the upper end of the bracket 2. The drive motor 43 is fixedly connected to the transmission wheel 41, which passes through the bracket 2 and is fixedly connected to the adjusting screw 32. By opening the drive assembly 4, the transmission wheel 41 is driven to rotate. When the drive assembly 4 is opened, the adjusting screw 32 rotates and the threaded part 33 moves. The movement of the threaded part 33 can drive the adjusting rod 34 to move, thereby enabling the detection assembly 5 to move. This increases the impact force and allows for the detection of hot-pressed buffer materials under different impact forces.
[0024] refer to Figure 1 Each of the outer sides of the bracket 2 is fixedly connected with a movable handle 7. The outer surface of the movable handle 7 is fixedly connected with an anti-slip pad. The movable handle 7 is fixedly connected to the bracket 2 by screws. The movable handle 7 makes it more convenient to move the device.
[0025] refer to Figure 1 and Figure 3 The fixing component 6 includes a fixing plate 61 disposed inside the bracket 2. A clamping plate 62 is slidably connected to the upper end of the fixing plate 61 on the inner side of the bracket 2. Mounting plates 63 are fixedly connected to both sides of the bracket 2. An electric push rod 64 is fixedly connected to the surface of the mounting plate 63. The other end of the electric push rod 64 is fixedly connected to the clamping plate 62. The inner side of the clamping plate 62 is slidably connected to the inner side of the bracket 2. A sliding groove 8 is provided on the inner side of the bracket 2. A sliding block 9 is fixedly connected to the inner side of the clamping plate 62. The sliding groove 8 and the sliding block 9 are slidably connected to each other. By placing the hot-pressed buffer material on the upper end of the fixing plate 61, the electric push rod 64 can be controlled to move. Under the action of the electric push rod 64, the clamping plate 62 moves downward, thereby fixing the hot-pressed buffer material. This allows for convenient testing of the hot-pressed buffer material and avoids displacement of the hot-pressed buffer material during testing.
[0026] refer to Figure 1 Both sides of the detection block 55 are slidably connected to the bracket 2. The sleeve plate 10 is slidably connected inside the adjustment groove 31. The sleeve plate 10 and the adjustment screw 32 are slidably inserted into each other. Both sides of the detection block 55 are fixedly connected to the connecting plate 11, which is fixedly connected to the sleeve plate 10. The sleeve plate 10 and the connecting plate 11 can limit the detection block 55 and prevent the detection block 55 from being bounced away by the hot-pressed buffer material when it falls.
[0027] Operating principle and advantages: First, the hot-pressed buffer material is placed on the upper end of the fixed plate 61. Then, the electric push rod 64 is moved by control, and the clamping plate 62 moves downward under the action of the electric push rod 64, thereby fixing the hot-pressed buffer material. This allows for convenient testing of the hot-pressed buffer material and avoids displacement of the material during testing. Then, the detection component 5 is moved to a suitable position by the adjusting component 3. The detection motor 59 is controlled to drive the active bevel gear 58 to rotate. The rotation of the active bevel gear 58 drives the driven bevel gear 57 to rotate, which in turn drives the moving screw 52 to rotate. The rotation of the moving screw 52 drives the moving part 53 to move outward, thereby disengaging the clamping block 54 from the detection block 55. 54 falls downwards, causing the detection block 55 to come into contact with the hot-pressed buffer material, thus impacting the material and allowing for observation of its condition. This enables the detection of the hot-pressed buffer material's integrity. Furthermore, opening the drive assembly 4 rotates the transmission wheel 41, causing the adjusting screw 32 to rotate and the threaded component 33 to move. The movement of the threaded component 33 moves the adjusting rod 34, thereby moving the detection assembly 5. This increases the impact force and allows for the detection of the hot-pressed buffer material under different impact conditions. Simultaneously, the sleeve plate 10 and connecting plate 11 limit the movement of the detection block 55, preventing it from being bounced off the hot-pressed buffer material during its fall.
