Description

Technical Field

[0001] The present invention relates to the field of screen detection technology, and in particular to a television screen production and processing detection device and a use method. Background Art

[0002] Screen inspection, especially for TV screens, typically only allows for basic optical property measurements and has relatively limited functionality. However, after a TV screen is produced and transported off the production line to the corresponding assembly line, direct assembly of the transported screen can lead to the following problems:

[0003] First, during the transportation from the manufacturing production line to the assembly line, the TV screen will inevitably encounter bumps during transportation. This bump will cause damage to the TV screen. Therefore, it is necessary to use this bump to conduct special inspections on the TV screen to observe the degree of damage caused by different bump amplitudes. In this way, the corresponding bump degree during transportation can be controlled and observed.

[0004] Secondly, during transportation, collisions may occur, resulting in impacts. In this case, it is necessary to promptly inspect the surface of the TV screen to detect whether the impact has caused irreversible bending on the surface of the TV screen. Usually, multiple groups of TV screens are impacted together, so it is necessary to inspect this group of TV screens to see if irreversible bending damage has occurred. This inspection is usually very time-consuming and labor-intensive, and it is impossible to quickly screen which screens have suffered irreversible bending damage.

[0005] To this end, we have designed a TV screen production, processing and testing device and its use method. Summary of the Invention

The screen clamping frame is provided with a placement groove that is adapted to the TV screen to be tested, and a rubber roller that is against the TV screen to be tested is provided on the inner wall of the placement groove facing the side of the TV screen to be tested.

[0010] Preferably, the threaded clamping portion comprises:

[0011] A through hole is provided on the mounting frame, and a bolt is threaded through the through hole, and a positioning block is provided at one end of the bolt for sliding in the through hole;

[0012] The swing frame rotates in the through hole through the first fixed shaft, and a slot adapted to the first fixed shaft is provided on the side of the positioning block facing the first fixed shaft.

[0013] Preferably, the side frame is provided with a side plate, the side plate is provided with a driving motor, the output end of the driving motor is fixed with a screw rod, and the screw rod drives the U-shaped positioning block to slide through the positioning assembly.

[0014] Preferably, a positioning slide is fixed on the side panel, a second sliding block adapted to the screw thread slides on the positioning slide, an electric telescopic rod is fixed to 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 through the sliding rail, and side fixing plates are symmetrically fixed on both sides of the first sliding block, and strip holes are opened on the side fixing plates. A second fixed shaft is fixed on the swing frame, and the side fixing plates push the swing frame to rotate on the mounting frame through the strip holes and the second fixed shaft.

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

[0017] Preferably, an extension frame is provided on the swing frame, the swing rod passes through the extension frame, an electromagnetic generator is fixed to 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, a lifting water-absorbing rope is wrapped around the outer side wall of the TV screen to be tested, and lifting slide bars are symmetrically provided on both sides of the TV screen to be tested. The lifting slide bars are installed on the side walls of the screen clamping frame, and fixed pulleys are provided on both lifting slide bars. Both ends of the water-absorbing rope are wrapped around the fixed pulleys, and the water-absorbing ropes between the TV screen to be tested and the fixed pulleys are cross-arranged.

[0019] A method for using a television screen production and processing detection device, the specific method of use is as follows:

[0020] S1: The TV screen to be tested is mounted on a swing frame on the mounting frame through four screen clamping frames, and then the bolts are rotated to drive the positioning block against the first fixed axis on the swing frame. Due to the relative movement of the positioning blocks on the mounting frame, the TV screen to be tested can be clamped on the mounting frame, completing the initial clamping and fixing;

[0021] S2: The TV screen to be tested needs to be tested for horizontal shaking. When the horizontal shaking amplitude needs to be adjusted, the measuring plate is pushed into the swing rod. Since the two sides of the trapezoidal top block are inclined, the positioning rod can be pushed up. By adjusting the position of the trapezoidal top block in the telescopic slot, the position of the extended positioning rod can also be determined. Then, the electromagnetic generator is turned on to 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, eventually causing the TV screen to move, and there will be rapid sliding and rapid stopping, simulating the bumping phenomenon during transportation;

[0022] When it is necessary to perform a bending test on the TV screen to be tested, the driving motor is turned on to drive the second sliding block to slide on the positioning slide, and the U-shaped positioning block will also move together with the first sliding block. Therefore, the movement of the first sliding block drives the swing frame to rotate on the mounting frame through the side fixing plate to realize the bending test of the TV screen to be tested. At this time, it is necessary to loosen the bent TV screen to be tested in time to observe whether the TV screen to be tested will suffer irreversible bending damage. At this time, the electric telescopic rod is turned on to lift the U-shaped positioning block, that is, the pushing effect of the first sliding block is released, and the TV screen to be tested will reset without external force. This step simulates the state of the TV screen to be tested being reset after being bent;

[0023] S3: The mounting frame is provided with a plurality of distance measuring sensors for detecting the TV screen to be detected, wherein the plurality of distance measuring sensors are linearly mounted on the mounting frame. The distance measuring sensors are for distance detection. If an irreversible bend occurs, the distance measuring sensors will detect the corresponding protrusions and depressions. The distance measuring sensors detect the abnormal distance and issue an early warning.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention turns on the electric telescopic rod to drive the U-shaped positioning block to lift and allow the U-shaped positioning block to separate from the first sliding block, thereby releasing the pushing effect on the first sliding block, that is, releasing the pushing effect of the first sliding block, and the TV screen to be tested will reset without external force. This step simulates the state of the TV screen to be tested being reset after being bent.

[0026] 2. By turning on the electromagnetic generator to generate magnetic poles opposite to the magnet block, due to the existence of the extension frame, the sliding of the swing arm will be affected by the positioning rod, so it can drive the swing arm to slide on the extension frame and the swing frame. In conjunction with the extended positioning rod, it has the effect of rapid sliding and sudden stopping of the TV screen to be tested, simulating the bumping phenomenon during transportation.

[0027] 3. In the present invention, when the two fixed pulleys are lifting and lowering with the water-absorbing rope, if the TV screen to be tested is in an irreversible bending state, the water-absorbing rope stained with ink will not be able to touch the sunken surface of the TV screen to be tested. Therefore, it is possible to clearly observe whether the TV screen to be tested has irreversible bending deformation and deformation caused by transportation collision.

[0040] Reference Figures 1-11 A TV screen production, processing and testing device includes a mounting frame 1, and a TV screen 2 to be tested mounted on the mounting frame 1. Swing frames 4 are installed at the four corners of the mounting frame 1, and the swing frames 4 are installed on the mounting frame 1 through threaded clamping parts, so that the TV screen 2 to be tested can be clamped and fixed, which facilitates the operation of the TV screen 2 to be tested.

[0041] The threaded clamping portion adopts a bolt clamping structure to install the swing frame 4 on the mounting frame 1. The threaded clamping portion includes a through hole 6. The through hole 6 is opened on the mounting frame 1. There are four through holes 6. The four through holes 6 are respectively arranged on both sides of the mounting frame 1. Figure 3 and Figure 4There are four through holes 6 in the state, and bolts 8 are threaded through the through holes 6. One end of the bolt 8 is rotated to provide 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 provided with a screen clamping frame 3 that is clamped at the four corners of the TV screen 2 to be tested. At this time, the screen clamping frame 3 is buckled at the four corners of the TV screen 2 to be tested, and the positioning block 7 is pushed in by rotating the bolt 8. The swing frame 4 rotates in the through hole 6 through the first fixed axis 5, so the positioning block 7 will press against the first fixed axis 5 and push the swing frame 4 to move, and the TV screen 2 to be tested can be tightly clamped by the swing frame 4.

[0043] Furthermore, the positioning block 7 is provided with a slot adapted to the first fixed shaft 5 on the side facing the first fixed shaft 5, so 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 sliding.

[0044] Reference Figure 1 , multiple side frames 12 are installed on one side of the mounting frame 1, and two side frames 12 are used, and are respectively arranged on the side walls of the mounting frame 1 with through holes 6. A U-shaped positioning block 21 is slidingly provided on the side frame 12, wherein the U-shaped positioning block 21 is moved up and down by an external driving device, and the U-shaped positioning block 21 is snapped with a first sliding block 15, and the first sliding block 15 slides on the side frame 12, and the first sliding block 15 drives 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 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 is rotatably connected to the first sliding block 15 through a telescopic rod. Therefore, during the sliding process of the first sliding block 15, the swing frame 4 can be driven to change its angle, thereby completing the bending of the TV screen 2 to be tested on the swing frame 4.

[0045] Then, the U-shaped positioning block 21 is lifted by an external driving device to separate the U-shaped positioning block 21 from the first sliding block 15. At this time, the first sliding block 15 is not 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 driving device adopts two electrically driven electric hydraulic cylinders, which are divided into electric hydraulic cylinder A and electric hydraulic cylinder B. Electric hydraulic cylinder A and electric hydraulic cylinder B are arranged vertically, wherein the output end of electric hydraulic cylinder A is connected to electric hydraulic cylinder B, and the output end of electric hydraulic cylinder B is connected to U-shaped positioning block 21, wherein side frame 12 is provided with side plate 13, and electric hydraulic cylinder A is installed on side plate 13, so that electric hydraulic cylinder A is turned on to push electric hydraulic cylinder B to move, and the U-shaped positioning block 21 at the output end of electric hydraulic cylinder B is stuck in the first sliding block 15, and then can move with the first sliding block 15, and then the electric hydraulic cylinder B is turned on to allow the U-shaped positioning block 21 to separate from the first sliding block 15. The peripheral driving device is a prior art and will not be elaborated on 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 State, since the side plate 13 is arranged at the end of the side frame 12, a drive motor 17 is provided on the side plate 13, and a screw rod 18 is fixed to the output end of the drive motor 17. The first slide block 15 slides on the side frame 12 through the slide rail 14, and the screw rod 18 drives the U-shaped positioning block 21 to slide through the positioning assembly. Therefore, after the drive motor 17 is turned on, the rotating screw rod 18 can push the positioning assembly to move, and finally drive the U-shaped positioning block 21 to move. The positioning assembly adopts the following structure:

[0049] A positioning slide 16 is fixed on the side panel 13, and a second slide block 19 that is threadably adapted to the screw rod 18 is sliding on the positioning slide 16. A threaded hole is provided on the second slide block 19, and the screw rod 18 passes through the threaded hole. An electric telescopic rod 20 is fixed to the bottom of the second slide block 19. Therefore, after turning on the drive motor 17, due to the limit of the positioning slide 16, the second slide block 19 slides along the positioning slide 16 with the electric telescopic rod 20.

[0050] Therefore, when a bending test is required for the TV screen 2 to be tested, the driving motor 17 is turned on to drive the second sliding block 19 to slide on the positioning slide 16, and the U-shaped positioning block 21 is also moved together with the first sliding block 15.

[0051] Reference Figure 5 and Figure 6In this state, the first sliding block 15 is symmetrically fixed with side fixing plates 22 on both sides, and a strip hole 23 is opened on the side fixing plate 22, and a second fixed shaft 28 is fixed on the swing frame 4. The side fixing plate 22 pushes the swing frame 4 to rotate on the mounting frame 1 through the strip hole 23 and the second fixed shaft 28. Therefore, as the first sliding block 15 slides, the side fixing plate 22 moves together, so the strip hole 23 on the side fixing plate 22 pushes the second fixed shaft 28 on the swing frame 4, and then pushes the swing frame 4 to swing on the mounting frame 1 through the first fixed shaft 5, which will realize the rotation from Figures 5 to 6 The state changes to realize the bending test of the TV screen 2 to be tested. At this time, it is necessary to loosen the bent TV screen 2 to be tested in time to observe whether the TV screen 2 to be tested will suffer irreversible bending damage.

[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, the U-shaped positioning block 21 is lifted and the U-shaped positioning block 21 is separated from the first sliding block 15, thereby releasing the pushing effect on the first sliding block 15. That is, the pushing effect of the first sliding block 15 is released, and the TV screen 2 to be tested will be reset without external force. This step simulates the state of the TV screen 2 to be tested being reset after being bent.

[0053] The TV screen 2 to be tested slides on the swing frame 4 through the swing rod 24, wherein the swing rod 24 is vertically fixed and passes through the screen clamping frame 3. A placement groove adapted to the TV screen 2 to be tested is provided on the screen clamping frame 3, and a rubber roller that abuts against the TV screen 2 to be tested is provided on the inner wall of the placement groove facing the side of the TV screen 2 to be tested. In this way, it is ensured that the screen clamping frame 3 does not contact the TV screen 2 to be tested, but is connected to the outer wall of the TV screen 2 to be tested through the rubber roller, thereby avoiding bending damage caused by direct contact between the screen clamping frame 3 and the TV 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 reset spring 25. Therefore, when it is necessary to detect the collision simulation state of the TV screen 2 to be detected, it is only necessary to push the swing rod 24 once to allow the TV screen 2 to be detected to 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 to be detected will be deformed in the state of sudden movement, and then under the action of the reset spring 25, the swing rod 24 is slid and reset on the swing frame 4. By changing the pushing force, the shaking force of the TV screen 2 to be detected can be simulated, and it can be observed whether the TV screen 2 to be detected is damaged.

[0055] In summary, the following options are available for simulating the horizontal shaking of the TV screen 2 to be detected:

[0056] An extension frame 26 is provided on the swing frame 4, and the swing rod 24 passes through the extension frame 26. A plurality of lifting positioning rods 33 are provided on the swing rod 24, and the positioning rods 33 slide on the swing rod 24 through the lifting holes 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 in which the swing rod 24 drives the TV screen 2 to be tested to slide. By controlling the extended position of the positioning rods 33, the active range of the swing rod 24 with the TV screen 2 to be tested is finally determined, wherein the bottom of the positioning rod 33 is chamfered to facilitate the trapezoidal top block 31 to shovel the positioning rod 33 from the bottom and lift and slide in the lifting hole 32.

[0057] A telescopic slot 30 is provided on the swing rod 24, and a trapezoidal top block 31 for lifting the positioning rod 33 slides in the telescopic slot 30. The trapezoidal top block 31 can only lift one positioning rod 33. A measuring plate 29 extending into the telescopic slot 30 slides on the swing rod 24, and one end of the measuring plate 29 is fixed to the trapezoidal top block 31. Therefore, by pulling out the measuring plate 29 at the end of the swing rod 24, the position of the trapezoidal top block 31 in the telescopic slot 30 is 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 to be tested is.

[0058] An electromagnetic generator 27 is fixed to the end of the swing rod 24, and a magnet block 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 to generate a magnetic pole opposite to the magnet block, due to the existence of the extension frame 26, the sliding of the swing rod 24 will be affected by the positioning rod 33, so it can drive the swing rod 24 to slide on the extension frame 26 and the swing frame 4, and cooperate with the extended positioning rod 33 to achieve the effect of rapid sliding and sudden stopping of the TV screen 2 to be tested, simulating the collision phenomenon during transportation.

[0059] Reference Figure 11 State, the mounting frame 1 is provided with a plurality of distance measuring sensors for detecting the TV screen 2 to be detected, wherein the plurality of distance measuring sensors are linearly mounted on the mounting frame 1, wherein the distance measuring sensors are for distance detection, and are arranged at the top and bottom of the inner wall of the mounting frame 1, and the detection direction is vertical, so that a distance measurement is formed. Figure 11The top-down state detection of the TV screen 2 to be detected is shown below. The dotted line is the detection interval of the ranging sensor, where the width of the detection interval is a, and the width occupied by the TV screen 2 to be detected in the normal state is b. If an irreversible bend occurs, forming a protrusion as shown in the figure, and the TV screen 2 to be detected has a recessed portion on the other side of the protrusion, then the ranging sensor will detect the corresponding protrusion and recessed portion. At this time, the remaining width of the detection interval is not ab, and a spacing abnormality will occur. The ranging sensor will issue an early warning. The ranging sensor is a prior art and will not be elaborated on here.

[0060] For the detection of the TV screen 2 to be detected, another detection method is provided:

[0061] The outer wall of the TV screen 2 to be tested is wrapped with a water-absorbing rope 11 that can be raised and lowered. Ink is absorbed on the water-absorbing rope 11, and the water-absorbing rope 11 is driven to rise and fall by an external lifting mechanism. The following options are available for the water-absorbing rope 11 to slide closely against the TV screen 2 to be tested:

[0062] Reference Figures 8-10 As shown, lifting slides 9 are symmetrically provided on both sides of the TV screen 2 to be tested, and the lifting slides 9 are installed on the side walls of the screen clamping frame 3, and fixed pulleys 10 are provided on the two lifting slides 9. The two ends of the water absorption rope 11 are wrapped around the fixed pulleys 10, and the water absorption rope 11 between the TV screen 2 to be tested and the fixed pulleys 10 are cross-arranged. This arrangement can ensure that the water absorption rope 11 is close to the two sides of the TV screen 2 to be tested, and can also ensure that the water absorption rope 11 is stably wrapped around the fixed pulleys 10. Under the action of the external driving device, the two fixed pulleys 10 are driven to rise and fall and slide on the lifting slides 9. The external driving device adopts a hydraulic rod assembly to drive the fixed pulley 10 to rise and fall and slide on the lifting slide 9. The hydraulic rod assembly is a prior art and will not be elaborated on here.

[0063] The water-absorbing rope 11 is adsorbed with ink, so when the two fixed pulleys 10 are lifting and lowering with the water-absorbing rope 11, if the TV screen 2 to be tested is in an irreversible bending state, the water-absorbing rope 11 stained with ink cannot touch the sunken surface of the TV screen 2 to be tested, so it is possible to clearly observe whether the TV screen 2 to be tested is in an irreversible bending deformation or deformation caused by transportation. It should be noted that a water-absorbing sponge for replenishing ink for the water-absorbing rope 11 is provided on the fixed pulley 10, so that when the water-absorbing rope 11 passes through the water-absorbing sponge, the ink can be absorbed by the water-absorbing rope 11. When the sponge is being tested, the ink will reach the water absorption rope 11 from the water absorption sponge, ensuring that there is always ink on the water absorption rope 11. Since the water absorption rope 11 is wrapped around the outer wall of the TV screen 2 to be tested, the water absorption rope 11 will slide close to the outer wall of the TV screen 2 to be tested. If the TV screen 2 to be tested is in an irreversible bending state, the water absorption rope 11 stained with ink will not be able to touch the sunken surface of the TV screen 2 to be tested. Therefore, it is possible to clearly observe whether the TV screen 2 to be tested has irreversible bending deformation and deformation caused by transportation and bumping.

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

[0065] S1: The TV screen 2 to be tested is mounted on the swing frame 4 on the mounting frame 1 through four screen clamping frames 3. Then, the bolt 8 is rotated to drive the positioning block 7 to press against the first fixed axis 5 on the swing frame 4. Due to the relative movement of the positioning blocks 7 on the mounting frame 1, the TV screen 2 to be tested can be clamped on the mounting frame 1, completing the preliminary clamping and fixing.

[0066] S2: A horizontal shaking test is performed on the TV screen 2 to detect whether the TV screen 2 is deformed when suddenly moved. Then, under the action of the reset spring 25, the swing rod 24 is slid and reset on the swing frame 4. By changing the pushing force, the shaking intensity of the TV screen 2 can be simulated to observe whether the TV screen 2 is damaged.

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

[0068] S3: The water-absorbing rope 11 slides closely against the outer wall of the TV screen 2 to be tested. If the TV screen 2 to be tested is in an irreversible bending state, the water-absorbing rope 11 stained with ink will not be able to touch the sunken surface of the TV screen 2 to be tested. Therefore, it is possible to clearly observe whether the TV screen 2 to be tested has irreversible bending deformation and deformation caused by transportation. It should be noted that a water-absorbing sponge is provided on the fixed pulley 10 to replenish ink for the water-absorbing rope 11. In this way, when the water-absorbing rope 11 passes through the water-absorbing sponge, the ink will reach the water-absorbing rope 11 from the water-absorbing sponge, ensuring that there is always ink on the water-absorbing rope 11.

[0069] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

10. A method for using a television screen production, processing and testing device, applied to a television screen production, processing and testing device according to claim 9, characterized in that: The specific usage is as follows: S1: The TV screen to be tested is mounted on a swing frame on the mounting frame through four screen clamping frames, and then the bolts are rotated to drive the positioning block against the first fixed axis on the swing frame. Due to the relative movement of the positioning blocks on the mounting frame, the TV screen to be tested can be clamped on the mounting frame, completing the initial clamping and fixing; S2: The TV screen to be tested needs to be tested for horizontal shaking. When the horizontal shaking amplitude needs to be adjusted, the measuring plate is pushed into the swing rod. Since the two sides of the trapezoidal top block are inclined, the positioning rod can be pushed up. By adjusting the position of the trapezoidal top block in the telescopic slot, the position of the extended positioning rod can also be determined. Then, the electromagnetic generator is turned on to 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, eventually causing the TV screen to move, and there will be rapid sliding and rapid stopping, simulating the bumping phenomenon during transportation; When it is necessary to perform a bending test on the TV screen to be tested, the driving motor is turned on to drive the second sliding block to slide on the positioning slide, and the U-shaped positioning block will also move together with the first sliding block. Therefore, the movement of the first sliding block drives the swing frame to rotate on the mounting frame through the side fixing plate to realize the bending test of the TV screen to be tested. At this time, it is necessary to loosen the bent TV screen to be tested in time to observe whether the TV screen to be tested will suffer irreversible bending damage. At this time, the electric telescopic rod is turned on to lift the U-shaped positioning block, that is, the pushing effect of the first sliding block is released, and the TV screen to be tested will reset without external force. This step simulates the state of the TV screen to be tested being reset after being bent; S3: The mounting frame is provided with a plurality of distance measuring sensors for detecting the TV screen to be detected, wherein the plurality of distance measuring sensors are linearly mounted on the mounting frame. The distance measuring sensors are for distance detection. If an irreversible bend occurs, the distance measuring sensors will detect the corresponding protrusions and depressions. The distance measuring sensors detect the abnormal distance and issue an early warning.
