The front side of the base 1 is connected to... There is a mounting bracket 16, on which a third motor 161 is mounted. The output shaft of the third motor 161 is connected to a second screw 17 at its rear end. Two movable plates 18 are slidably connected to the second screw 17. The movable plates 18 can initially fix the LCD screen. Connecting blocks 19 are symmetrically connected to the left and right sides of the outer side of the testing device 5. A guide frame 191 is slidably connected inside each connecting block 19. The two guide frames 191 on the same side are fixedly connected to the movable plates 18. A motor 20 is mounted on the right side of each of the two movable plates 18. The output shaft of the motor 20 passes through the movable plate 18 and is connected to a lead screw 21. Two clamping plates 22 are slidably connected to the lead screw 21. The clamping plates 22 are used to further fix the LCD screen. The two clamping plates 22 on the same side face each other. Each side is connected to a sponge pad 221, which provides cushioning to prevent damage to the LCD screen during fixing. A pressure-sensitive assembly is provided on the pressure-sensitive plate 6, including a mounting plate 7, a second motor 8, a protective shell 81, a first screw 9, a sliding block 91, a first connecting plate 10, a locking rod 11, a fixing block 12, a second connecting plate 13, and a pressure-sensitive block 14. The mounting plate 7 is connected to the left side of the pressure-sensitive plate 6, and the second motor 8 is mounted on the upper part of the mounting plate 7. The protective shell 81 is connected to the upper part of the mounting plate 7 and is located outside the second motor 8, protecting it. The first screw 9 is connected to the right end of the output shaft of the second motor 8, and a sliding block 91 is slidably connected to the first screw 9. 1. It can slide along the first screw 9. A second connecting plate 13 is placed on the lower side of the sliding block 91. The second connecting plate 13 is used for the installation and replacement of the pressure testing block 14. The first connecting plate 10 is symmetrically connected to the front and back of the second connecting plate 13. The two first connecting plates 10 are slidably connected with the locking rods 11. The locking rods 11 are used to fix the position of the second connecting plate 13. The second connecting plate 13 is symmetrically connected with the front and back of the second connecting plate 13. The two locking rods 11 pass through the two fixing blocks 12 and engage with the second connecting plate 13 and the sliding block 91. Multiple pressure testing blocks 14 are evenly spaced at the bottom of the second connecting plate 13. The multiple pressure testing blocks 14 are made of hard alloy. The pressure testing blocks 14 can directly contact and apply pressure to the surface of the LCD liquid crystal display screen to perform pressure resistance testing.
[0021] During the LCD production process, when this device is used to perform a pressure test on the LCD screen, the operator places the LCD screen to be tested on the conveyor 4, then starts the first motor 3. The output shaft of the first motor 3 drives the conveyor 4 to rotate, and the conveyor 4 transports the LCD screen to be tested to the right. When the LCD screen is transported to below the pressure testing plate 6, the first motor 3 is turned off, and the third motor 161 is started. The output shaft of the third motor 161 drives the second screw 17 to rotate, and the second screw 17 drives the two moving plates 18 to move inward. The two moving plates 18 drive the guide frame 191 connected to them to move inward along the corresponding connecting block 19 until the two moving plates 18 move to the position of the LCD screen. The LCD screen is brought into contact with and secured. After the LCD screen is secured, the third motor 161 is turned off. Next, the operator starts two motors 20, which drive the lead screws 21 connected to them to rotate. The lead screws 21 drive the two clamping plates 22 on them to move inward until all four clamping plates 22 move to contact the LCD screen and further secure it. After the LCD screen is secured, the two motors 20 are turned off. Next, the operator starts the testing equipment 5 through the control panel 101, causing the pressure plate 6 to move all its components downward until the pressure block 14 moves to contact the surface of the LCD screen and tests the LCD screen. The LCD screen undergoes a pressure test. During this process, the operator starts the second motor 8. The output shaft of the second motor 8 drives the first screw 9 to rotate. The first screw 9 drives the sliding block 91 and all its components to move to the left, causing the pressure testing block 14 to move and test the LCD screen. If the LCD screen is damaged during the pressure test, it is recorded as failing the LCD screen pressure test; otherwise, if the LCD screen is not damaged, it is recorded as passing the LCD screen pressure test. After the LCD screen pressure test is completed, the second motor 8 is turned off. At this time, the pressure testing plate 6 moves upward along the testing equipment 5, along with all its components. When the pressure testing plate 6 and all its components move to the initial position... During the initial positioning, the operator shuts down the testing equipment 5 via control panel 101, then starts the two motors 20 in reverse. The output shafts of the two motors 20 drive the lead screws 21 connected to them to rotate in reverse. The lead screws 21 drive the two clamping plates 22 on them to move outward. When the four clamping plates 22 have moved to their initial positions, the two motors 20 are shut off. Then, the operator starts the third motor 161 in reverse. The output shaft of the third motor 161 drives the second screw 17 to rotate in reverse. The second screw 17 drives the two moving plates 18 to move outward. The two moving plates 18 drive the guide frames 191 connected to them to move outward along the corresponding connecting blocks 19. When the two moving plates 18 have moved to their initial positions, the third motor 161 is shut off.The staff then restarted the first motor 3, which drove the conveyor 4 to rotate. The conveyor 4 continued to transport the LCD screens after the pressure test to the right until they were in a position easily accessible for removal. The LCD screens were then removed. This process was repeated until all LCD screens had undergone pressure testing. The first motor 3 was then turned off. When a different pressure testing block 14 needed to be replaced, the staff pulled the two levers 11 outwards along the corresponding first connecting plate 10. Once the levers 11 were on the corresponding fixing block 12, the second connecting plate 13 was removed. The new second connecting plate 13 was then placed under the sliding block 91 and inserted into it. The two levers 11 were then pushed inwards along the corresponding first connecting plate 10 until they were inserted into the contact area between the new second connecting plate 13 and the sliding block 91. The levers 11 were then stopped, ensuring the new pressure testing block 14 was securely fixed.
