Description

Technical Field

[0001] This invention relates to the field of screen inspection technology, and in particular to a television screen production and processing inspection device and its usage method. Background Technology

[0002] Devices for screen inspection, especially for television screens, typically only perform basic optical characteristic measurements and have limited functionality. However, after television screens are manufactured and transported off the production line to the corresponding assembly line, directly assembling these transported screens would lead to the following problems:

[0003] First, during the process of transporting the TV screen from the manufacturing production line to the assembly line, the TV screen will inevitably encounter bumps during transportation. These bumps can damage the TV screen. Therefore, it is necessary to use this bump situation to conduct special testing on the TV screen, observe the degree of damage to the TV screen due to different bump amplitudes, and then control the degree of bumps during the corresponding transportation process and observe the detection.

[0004] Secondly, collisions and impacts may occur during transportation, requiring timely inspection of the TV screen surface to check whether the impact has caused irreversible bending. Usually, multiple TV screens are impacted at the same time, so it is necessary to check the group of TV screens for irreversible bending damage. This inspection is usually very time-consuming and labor-intensive, and it is not possible to quickly screen which screens have irreversible bending damage.

[0005] To address this, we designed a television screen production, processing, and testing device and its usage method. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that traditional inspection methods in the prior art are usually very time-consuming and labor-intensive, and cannot quickly screen which screens have irreversible bending. Therefore, this invention proposes a television screen production and processing inspection device and its usage method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A television screen manufacturing and testing device includes a mounting frame and a television screen to be tested mounted on the mounting frame. Swing frames are installed at each of the four corners of the mounting frame, and the swing frames are mounted on the mounting frame via threaded clamping parts. Multiple side frames are installed on one side of the mounting frame, and a lifting U-shaped positioning block is slidably mounted on the side frame. The U-shaped positioning block engages with a first sliding block, which slides on the side frame. The first sliding block drives the swing frames on both sides to rotate on the mounting frame and bend the television screen to be tested. The television screen to be tested slides on the swing frames via swing rods. Multiple distance sensors for detecting the television screen to be tested are installed on the mounting frame.

[0009] Preferably, the swing frame is provided with screen clamping frames that clamp the four corners of the TV screen to be tested, and the swing rod is vertically fixed through the screen clamping frame. The swing rod slides through the swing frame, and one end of the swing rod is reset on the swing frame by a return spring. The screen clamping frame is provided with a mounting groove that is adapted to the TV screen to be tested, and a rubber roller that abuts against the TV screen to be tested is provided on the inner wall of the mounting groove facing the TV screen to be tested.

[0010] Preferably, the threaded clamping part includes:

[0011] A through hole is provided on the mounting frame, and a bolt is threaded through the through hole. One end of the bolt is equipped with a positioning block that slides in the through hole.

[0012] The swing frame rotates within the through hole via the first fixed shaft, and the positioning block has a slot adapted to the first fixed shaft on the side facing the first fixed shaft.

[0013] Preferably, a side plate is provided on the side frame, a drive motor is provided on the side plate, a lead screw is fixed at the output end of the drive motor, and the lead screw drives the U-shaped positioning block to slide through the positioning component.

[0014] Preferably, a positioning slide plate is fixed on the side plate, and a second sliding block adapted to the screw thread slides on the positioning slide plate. An electric telescopic rod is fixed at the bottom of the second sliding block, and the output end of the electric telescopic rod is connected to the U-shaped positioning block.

[0015] Preferably, the first sliding block slides on the side frame via a slide rail, and side fixing plates are symmetrically fixed on both sides of the first sliding block. The side fixing plates are provided with strip holes, and a second fixing shaft is fixed on the swing frame. The side fixing plates push the swing frame to rotate on the mounting frame through the strip holes and the second fixing shaft.

[0016] Preferably, the swing arm is provided with multiple lifting positioning rods, and the positioning rods slide on the swing arm through lifting holes. The swing arm is provided with a telescopic groove, and a trapezoidal top block that lifts the positioning rod slides in the telescopic groove. A measuring plate that extends into the telescopic groove slides on the swing arm, and one end of the measuring plate is fixed to the trapezoidal top block.

[0017] Preferably, the swing frame is provided with an extension frame, the swing rod passes through the extension frame, an electromagnetic generator is fixed at the end of the swing rod, and a magnet block is provided on the side of the extension frame facing the electromagnetic generator.

[0018] Preferably, the outer wall of the TV screen to be tested is wrapped with a lifting and absorbing rope, and the two sides of the TV screen to be tested are symmetrically provided with lifting slide rods. The lifting slide rods are installed on the side wall of the screen clamping frame, and each of the two lifting slide rods is provided with a fixed pulley. The two ends of the water-absorbing rope are wrapped around the fixed pulleys, and the water-absorbing rope between the TV screen to be tested and the fixed pulleys is arranged in a cross pattern.

[0019] A method for using a television screen production, processing, and testing device is as follows:

[0020] S1: The TV screen to be tested is mounted on the swing frame on the mounting frame using four screen clamps. Then, the bolts are rotated to drive the positioning blocks to abut against the first fixed shaft on the swing frame. Since the positioning blocks on the mounting frame move relative to each other, the TV screen to be tested can be clamped on the mounting frame, completing the initial clamping and fixing.

[0021] S2: A horizontal shaking test needs to be performed on the TV screen to be tested. When the horizontal shaking amplitude needs to be adjusted, push the measuring plate into the swing rod. Since the two sides of the trapezoidal top block are inclined, the positioning rod can be lifted. By adjusting the position of the trapezoidal top block in the telescopic groove, the position of the extended positioning rod can also be determined. Then, turn on the electromagnetic generator and generate a magnetic pole opposite to that of the magnet block. At this time, the swing rod slides on the swing frame. Due to the existence of the extension frame, the sliding of the swing rod will be affected by the positioning rod, which will eventually cause the TV screen to be tested to move. There will be a phenomenon of rapid sliding and rapid stopping, simulating the collision phenomenon under transportation conditions.

[0022] When a bending test is required on the TV screen to be tested, the drive motor is turned on to move the second sliding block on the positioning slide plate. This also moves the first sliding block along with the U-shaped positioning block, which is locked in place by the first sliding block. Therefore, the movement of the first sliding block causes the swing frame to rotate on the mounting frame through the side fixing plate, thus realizing the bending test of the TV screen to be tested. At this time, the bent TV screen to be tested needs to be released in time to observe whether irreversible bending damage will occur. Then, the electric telescopic rod is turned on to lift the U-shaped positioning block, which releases the pushing effect of the first sliding block. The TV screen to be tested will return to its original position without external force. This step simulates the state of the TV screen to be tested after bending and returning to its original position.

[0023] S3: The mounting frame is equipped with multiple distance sensors that detect the screen of the TV to be tested. These multiple distance sensors are linearly mounted on the mounting frame. The distance sensors detect distance. If an irreversible bend occurs, the distance sensors will detect the corresponding protrusion and depression. The distance sensors will detect the abnormal distance and issue an early warning.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. In this invention, the electric telescopic rod is activated to lift the U-shaped positioning block and disengage it from the first sliding block, thereby releasing the pushing effect on the first sliding block. In other words, the pushing effect of the first sliding block is released, and the TV screen under test will reset without external force. This step simulates the state of the TV screen under test after bending and resetting.

[0026] 2. By turning on the electromagnetic generator to generate a magnetic pole opposite to that of the magnet block, the sliding of the swing arm will be affected by the positioning rod due to the presence of the extension frame. Therefore, it can drive the swing arm to slide on the extension frame and the swing frame. Together with the extended positioning rod, it achieves the effect of rapid sliding and sudden stopping of the TV screen to be tested, simulating the collision phenomenon during transportation.

[0027] 3. In the process of raising and lowering the two fixed pulleys with the water-absorbing rope in this invention, if the screen of the TV to be tested is irreversibly bent, the water-absorbing rope with ink will not be able to reach the recessed surface of the screen. Therefore, it is possible to clearly observe whether the screen of the TV to be tested has undergone irreversible bending deformation and deformation caused by handling and bumping.

[0040] Reference Figures 1-11 A television screen production, processing and testing device includes a mounting frame 1 and a television screen 2 to be tested mounted on the mounting frame 1. A swing bracket 4 is installed at each of the four corners of the mounting frame 1, and the swing bracket 4 is mounted on the mounting frame 1 through a threaded clamping part. This can complete the clamping and fixing of the television screen 2 to be tested, which facilitates the operation of the television screen 2 to be tested.

[0041] The threaded clamping part adopts a bolt clamping structure to install the swing frame 4 on the mounting frame 1. The threaded clamping part includes through holes 6, which are formed on the mounting frame 1. There are four through holes 6, which are respectively set on the two opposite sides of the mounting frame 1. (Refer to...) Figure 3 and Figure 4The four through holes 6 are in a certain state, and bolts 8 are threaded through the through holes 6. One end of the bolt 8 is provided with a positioning block 7 that slides in the through hole 6. Therefore, rotating the bolt 8 will push the positioning block 7 to slide in the through hole 6.

[0042] The swing frame 4 is equipped with screen clamping frames 3 that clamp the four corners of the TV screen 2 to be tested. At this time, the screen clamping frames 3 are snapped into the four corners of the TV screen 2 to be tested, and the positioning blocks 7 are pushed forward by rotating the bolts 8. The swing frame 4 rotates in the through hole 6 through the first fixed shaft 5. Therefore, the positioning blocks 7 will abut against the first fixed shaft 5 and push the swing frame 4 to move, so that the TV screen 2 to be tested can be clamped tightly by the swing frame 4.

[0043] Furthermore, the positioning block 7 has a slot that matches the first fixed shaft 5 on the side facing the first fixed shaft 5. Therefore, the positioning block 7 not only clamps the first fixed shaft 5, but also provides clamping for the rotation of the first fixed shaft 5 to prevent slippage.

[0044] Reference Figure 1 Multiple side frames 12 are installed on one side of the mounting frame 1. Two side frames 12 are used and are respectively set on the side wall of the mounting frame 1 with through holes 6. U-shaped positioning blocks 21 are slidably installed on the side frames 12. The U-shaped positioning blocks 21 are moved and raised by an external driving device. The U-shaped positioning blocks 21 are engaged with the first sliding blocks 15, and the first sliding blocks 15 slide on the side frames 12. The first sliding blocks 15 drive the swing frames 4 on both sides to rotate on the mounting frame 1 and bend the TV screen 2 to be tested. Therefore, the external driving device pushes the first sliding blocks 15 to slide on the side frames 12 through the U-shaped positioning blocks 21. It should be noted that the swing frames 4 and the first sliding blocks 15 are rotatably connected by telescopic rods. Therefore, during the sliding of the first sliding blocks 15, the angle of the swing frames 4 can be changed, thereby completing the bending of the TV screen 2 to be tested on the swing frames 4.

[0045] Then, the U-shaped positioning block 21 is lifted by the external drive device, so that the U-shaped positioning block 21 is separated from the first sliding block 15. At this time, the first sliding block 15 is no longer limited by the U-shaped positioning block 21, and the TV screen 2 to be tested is elastic, so the TV screen 2 to be tested will return to its position.

[0046] It should be noted that the peripheral drive device uses two electrically driven electro-hydraulic cylinders, namely electro-hydraulic cylinder A and electro-hydraulic cylinder B. Electro-hydraulic cylinder A and electro-hydraulic cylinder B are arranged vertically. The output end of electro-hydraulic cylinder A is connected to electro-hydraulic cylinder B, and the output end of electro-hydraulic cylinder B is connected to U-shaped positioning block 21. Side plate 13 is provided on the side frame 12, and electro-hydraulic cylinder A is mounted on side plate 13. Therefore, when electro-hydraulic cylinder A is activated, it pushes electro-hydraulic cylinder B to move. The U-shaped positioning block 21 at the output end of electro-hydraulic cylinder B engages with the first sliding block 15, thus moving the first sliding block 15 together. Then, electro-hydraulic cylinder B is activated to disengage the U-shaped positioning block 21 from the first sliding block 15. The peripheral drive device is existing technology and will not be elaborated on further here.

[0047] The following options are also available for the sliding of the first sliding block 15 on the side frame 12:

[0048] Reference Figure 1 and Figure 2 In this configuration, since the side plate 13 is located at the end of the side frame 12, and a drive motor 17 is mounted on the side plate 13, with a lead screw 18 fixed to the output end of the drive motor 17, the first sliding block 15 slides on the side frame 12 via the slide rail 14, and the lead screw 18 drives the U-shaped positioning block 21 to slide via the positioning component. Therefore, after the drive motor 17 is turned on, the rotating lead screw 18 can push the positioning component to move, ultimately driving the U-shaped positioning block 21 to move. The positioning component adopts the following structure:

[0049] A positioning slide plate 16 is fixed on the side plate 13. A second sliding block 19 that is threaded and adapted to the lead screw 18 slides on the positioning slide plate 16. A threaded hole is opened on the second sliding block 19, through which the lead screw 18 passes. An electric telescopic rod 20 is fixed at the bottom of the second sliding block 19. Therefore, after the drive motor 17 is turned on, the second sliding block 19 slides along the positioning slide plate 16 with the electric telescopic rod 20 due to the limitation of the positioning slide plate 16.

[0050] Therefore, when the TV screen 2 to be tested needs to be bent, the drive motor 17 is turned on to drive the second sliding block 19 to slide on the positioning slide plate 16, which will also move the U-shaped positioning block 21 along with the first sliding block 15.

[0051] Reference Figure 5 and Figure 6In this configuration, the first sliding block 15 has symmetrically fixed side fixing plates 22 on both sides, and the side fixing plates 22 have slotted holes 23. A second fixing shaft 28 is fixed to the swing frame 4. The side fixing plates 22 push the swing frame 4 to rotate on the mounting frame 1 through the slotted holes 23 and the second fixing shaft 28. Therefore, as the first sliding block 15 slides, it moves the side fixing plates 22 together. Thus, the slotted holes 23 on the side fixing plates 22 push the second fixing shaft 28 on the swing frame 4, and then push the swing frame 4 to swing on the mounting frame 1 through the first fixing shaft 5, achieving the desired movement from... Figures 5 to 6 The state change is used to perform a bending test on the TV screen 2 under test. At this time, it is necessary to release the bent TV screen 2 under test in time and observe whether irreversible bending damage will occur.

[0052] The output end of the electric telescopic rod 20 is connected to the U-shaped positioning block 21. When the electric telescopic rod 20 is turned on, it drives the U-shaped positioning block 21 to rise and disengage from the first sliding block 15, thereby releasing the pushing effect on the first sliding block 15. The TV screen 2 under test will reset without external force. This step simulates the state of the TV screen 2 under test after bending and resetting.

[0053] The television screen 2 to be tested slides on the swing frame 4 via a swing rod 24. The swing rod 24 is vertically fixed and passes through the screen clamping frame 3. The screen clamping frame 3 has a mounting slot adapted to the television screen 2 to be tested, and a rubber roller is provided on the inner wall of the mounting slot facing the television screen 2 to be tested, which abuts against the television screen 2. This ensures that the screen clamping frame 3 does not contact the television screen 2 to be tested, but rather contacts the outer wall of the television screen 2 to be tested through the rubber roller. This avoids bending damage caused by direct contact between the screen clamping frame 3 and the television screen 2 to be tested during subsequent bending tests.

[0054] The swing rod 24 slides through the swing frame 4, and one end of the swing rod 24 is reset on the swing frame 4 by the return spring 25. Therefore, when it is necessary to detect the collision simulation state of the TV screen 2 under test, it is only necessary to push the swing rod 24 once to make the TV screen 2 under test slide on the swing frame 4 through the swing rod 24 to simulate the state of sudden sliding and detect whether the TV screen 2 under test will deform under the state of sudden movement. Then, under the action of the return spring 25, the swing rod 24 slides back to the swing frame 4. By changing the pushing force, the shaking force of the TV screen 2 under test can be simulated and whether the TV screen 2 under test is damaged can be observed.

[0055] In summary, the following options are also available for simulating the horizontal shaking of the television screen 2 under test:

[0056] The swing frame 4 is equipped with an extension frame 26, and the swing rod 24 passes through the extension frame 26. The swing rod 24 is equipped with multiple lifting positioning rods 33, and the positioning rods 33 slide on the swing rod 24 through the lifting hole 32. It should be noted that as the swing rod 24 slides on the swing frame 4 and the extension frame 26, it will be limited by the extended positioning rods 33 during the sliding process. That is, the closer the extended positioning rods 33 are to the mounting frame 1, the smaller the range of the swing rod 24 will carry the TV screen 2 to be tested to slide. By controlling the extension position of the positioning rods 33, the range of movement of the swing rod 24 carrying the TV screen 2 to be tested is finally determined. The bottom of the positioning rods 33 is chamfered, which makes it easy for the trapezoidal top block 31 to lift the positioning rods 33 from the bottom and slide them up and down in the lifting hole 32.

[0057] The swing rod 24 has a telescopic groove 30, and a trapezoidal top block 31 that lifts the positioning rod 33 slides in the telescopic groove 30. The trapezoidal top block 31 can only lift one positioning rod 33. A measuring plate 29 that extends into the telescopic groove 30 slides on the swing rod 24. One end of the measuring plate 29 is fixed to the trapezoidal top block 31. Therefore, by pulling the measuring plate 29 at the end of the swing rod 24, the position of the trapezoidal top block 31 in the telescopic groove 30 can be determined according to the measuring scale on the measuring plate 29. That is, the longer the measuring plate 29 is pulled out, the closer the position of the trapezoidal top block 31 lifting the positioning rod 33 is to the extension frame 26, and the smaller the shaking amplitude of the simulated TV screen 2 under test.

[0058] An electromagnetic generator 27 is fixed to the end of the swing arm 24, and a magnet is provided on the side of the extension frame 26 facing the electromagnetic generator 27. It should be noted that by turning on the electromagnetic generator 27, a magnetic pole opposite to that of the magnet is generated. Due to the presence of the extension frame 26, the sliding of the swing arm 24 is affected by the positioning rod 33. Therefore, the swing arm 24 can slide on the extension frame 26 and the swing frame 4. The extended positioning rod 33 plays a role in the rapid sliding and sudden stopping effect of the TV screen 2 under test, simulating the collision phenomenon during transportation.

[0059] Reference Figure 11 In this configuration, the mounting frame 1 is equipped with multiple distance sensors for detecting the television screen 2 under test. These sensors are linearly mounted on the mounting frame 1 and are used for distance detection. They are located at the top and bottom of the inner wall of the mounting frame 1, with a vertical detection orientation. This configuration creates... Figure 11The detection is performed from above on the TV screen 2 to be tested. The dotted line represents the detection range of the distance sensor, where the width of the detection range is 'a'. The normal width occupied by the TV screen 2 is 'b'. If an irreversible bend occurs, forming the protrusion shown in the figure, and the TV screen 2 has a recess on the other side of the protrusion, then the distance sensor will detect the corresponding protrusion and recess. At this time, the remaining width of the detection range is not 'ab', which will result in an abnormal spacing. The distance sensor will then issue a warning. The distance sensor is existing technology and will not be discussed in detail here.

[0060] Another testing method is also provided for testing the TV screen 2 to be tested:

[0061] The outer wall of the TV screen 2 under test is wrapped with a lifting and lowering absorbent rope 11, which is coated with ink. The absorbent rope 11 is raised and lowered by an external lifting mechanism. The following options are available for the absorbent rope 11 to slide close to the TV screen 2 under test:

[0062] Reference Figures 8-10 As shown, the TV screen 2 under test is symmetrically provided with lifting slide rods 9 on both sides. The lifting slide rods 9 are installed on the side wall of the screen clamping frame 3, and each of the two lifting slide rods 9 is provided with a fixed pulley 10. The two ends of the water-absorbing pull rope 11 are wrapped around the fixed pulley 10. The water-absorbing pull rope 11 between the TV screen 2 under test and the fixed pulley 10 is arranged in a cross manner. This arrangement can ensure that the water-absorbing pull rope 11 is in close contact with both sides of the TV screen 2 under test, and at the same time, it can also ensure that the water-absorbing pull rope 11 is stably wrapped around the fixed pulley 10. Under the action of the external driving device, the two fixed pulleys 10 are driven to slide up and down on the lifting slide rods 9. The external driving device adopts a hydraulic rod assembly to drive the fixed pulleys 10 to slide up and down on the lifting slide rods 9. The hydraulic rod assembly is existing technology and will not be described in detail here.

[0063] The absorbent pull rope 11 is coated with ink. Therefore, during the lifting and lowering process of the two fixed pulleys 10 carrying the absorbent pull rope 11, if the TV screen 2 under test becomes irreversibly bent, the ink-soaked absorbent pull rope 11 will not be able to reach the recessed surface of the TV screen 2 under test. Thus, it is possible to clearly observe whether the TV screen 2 under test has undergone irreversible bending deformation or deformation due to handling and impact. It should be noted that the fixed pulleys 10 are equipped with absorbent sponges to replenish the ink on the absorbent pull rope 11. This allows the absorbent pull rope 11 to pass through the absorbent sponge... When the sponge is in use, the ink will travel from the absorbent sponge to the absorbent pull rope 11, ensuring that the absorbent pull rope 11 always has ink on it. Since the absorbent pull rope 11 covers the outer wall of the TV screen 2 under test, it will slide closely against the outer wall of the TV screen 2 under test. If the TV screen 2 under test is irreversibly bent, the ink-soaked absorbent pull rope 11 will not be able to reach the recessed surface of the TV screen 2 under test. Therefore, it is possible to clearly observe whether the TV screen 2 under test has undergone irreversible bending deformation and deformation caused by handling and bumping.

[0064] The working principle of this invention is as follows:

[0065] S1: The TV screen 2 to be tested is mounted on the swing frame 4 located on the mounting frame 1 through four screen clamping brackets 3. Then, the bolt 8 is rotated to drive the positioning block 7 to abut against the first fixed shaft 5 on the swing frame 4. Since the positioning block 7 on the mounting frame 1 moves relative to each other, the TV screen 2 to be tested can be clamped on the mounting frame 1 to complete the initial clamping and fixing.

[0066] S2: A horizontal shaking test needs to be performed on the TV screen 2 to be tested, that is, to test whether the TV screen 2 to be tested will deform under sudden movement. Then, under the action of the return spring 25, the swing rod 24 slides back to the swing frame 4. By changing the pushing force, the shaking force of the TV screen 2 to be tested can be simulated, and it can be observed whether the TV screen 2 to be tested is damaged.

[0067] When a bending test is required on the TV screen 2 to be tested, the peripheral drive device pushes the first sliding block 15 to slide on the side frame 12 through the U-shaped positioning block 21. It should be noted that the swing frame 4 and the first sliding block 15 are rotatably connected through the telescopic rod. Therefore, during the sliding of the first sliding block 15, the swing frame 4 can be driven to change angle, thereby completing the bending of the TV screen 2 to be tested on the swing frame 4.

[0068] S3: The absorbent pull rope 11 slides close to the outer wall of the TV screen 2 under test. If the TV screen 2 under test is irreversibly bent, the ink-soaked absorbent pull rope 11 will not be able to reach the recessed surface of the TV screen 2 under test. Therefore, it is possible to clearly observe whether the TV screen 2 under test has undergone irreversible bending deformation and deformation caused by handling and bumping. It should be noted that the fixed pulley 10 is equipped with an absorbent sponge to replenish the ink on the absorbent pull rope 11. In this way, when the absorbent pull rope 11 passes through the absorbent sponge, the ink will reach the absorbent pull rope 11 from the absorbent sponge, ensuring that the absorbent pull rope 11 always has ink on it.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method of using a television screen production, processing, and testing device, applied to the television screen production, processing, and testing device of claim 5, characterized in that, The specific usage method is as follows: S1: The TV screen to be tested is mounted on the swing frame on the mounting frame using four screen clamps. Then, the bolts are rotated to drive the positioning blocks to abut against the first fixed shaft on the swing frame. Since the positioning blocks on the mounting frame move relative to each other, the TV screen to be tested can be clamped on the mounting frame, completing the initial clamping and fixing. S2: A horizontal shaking test needs to be performed on the TV screen to be tested. When the horizontal shaking amplitude needs to be adjusted, push the measuring plate into the swing rod. Since the two sides of the trapezoidal top block are inclined, the positioning rod can be lifted. By adjusting the position of the trapezoidal top block in the telescopic groove, the position of the extended positioning rod can also be determined. Then, turn on the electromagnetic generator and generate a magnetic pole opposite to that of the magnet block. At this time, the swing rod slides on the swing frame. Due to the existence of the extension frame, the sliding of the swing rod will be affected by the positioning rod, which will eventually cause the TV screen to be tested to move. There will be a phenomenon of rapid sliding and rapid stopping, simulating the collision phenomenon under transportation conditions. When a bending test is required on the TV screen to be tested, the drive motor is turned on to move the second sliding block on the positioning slide plate. This also moves the first sliding block along with the U-shaped positioning block, which is locked in place by the first sliding block. Therefore, the movement of the first sliding block causes the swing frame to rotate on the mounting frame through the side fixing plate, thus realizing the bending test of the TV screen to be tested. At this time, the bent TV screen to be tested needs to be released in time to observe whether irreversible bending damage will occur. Then, the electric telescopic rod is turned on to lift the U-shaped positioning block, which releases the pushing effect of the first sliding block. The TV screen to be tested will return to its original position without external force. This step simulates the state of the TV screen to be tested after bending and returning to its original position. S3: The mounting frame is equipped with multiple distance sensors that detect the screen of the TV to be tested. These multiple distance sensors are linearly mounted on the mounting frame. The distance sensors detect distance. If an irreversible bend occurs, the distance sensors will detect the corresponding protrusions and depressions, detect the abnormal distance, and issue a warning.
