Description

Technical Field

[0001] This invention belongs to the field of pressure resistance testing technology, specifically a pressure resistance testing device for touch screen panels. Background Technology

[0002] A touch screen is a sensory liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display screen. Touch screen panels need to be pressure tested during production.

[0003] Existing technologies also offer some solutions, such as a Chinese patent application (CN214749427U) that discloses a glass panel compression resistance testing device. This device relates to the field of glass panel compression resistance testing technology and includes a base with a support frame mounted on its top. A rotating rod passes through the inner top of the support frame. By starting a motor, the rotating rod rotates, causing a movable plate mounted below its outer wall to move up and down. Therefore, when performing compression resistance testing on the glass panel at the first support plate, the glass panel on the surface of the second support plate can be replaced or installed simultaneously; conversely, the installation can proceed in the opposite direction. This effectively improves the device's working efficiency.

[0004] Although the above technical solution can replace the glass panel on the surface of the second support plate at the same time when the glass panel on the first support plate is subjected to compression testing, there are still other problems in actual use. For example, when testing the panel, it is generally necessary to press it until it breaks. Currently, the broken glass fragments are mostly handled manually by the staff, which is inconvenient.

[0005] Therefore, the present invention provides a pressure resistance testing device for touch screen panels. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A touchscreen panel pressure resistance testing device according to this invention includes a testing platform. A rotating plate is rotatably mounted above the testing platform. The bottom of the rotating plate is connected to the output end of a motor, which is installed inside the testing platform. Multiple support frames are mounted on the upper surface of the rotating plate. A touchscreen panel to be tested is placed on the surface of each support frame. A limiting plate is rotatably mounted above each support frame. Two limiting plates are provided on the surface of each support frame. A collection frame is installed inside the rotating plate, located below the limiting plate. An mounting plate is mounted on the side wall of the testing platform. A pressure detection head is provided at the end of the mounting plate. The pressure detection head is connected to a display screen via a power cord. The display screen is mounted above the testing platform.

[0008] Preferably, a baffle is installed on the upper surface of each of the limiting plates, the baffle is used to block the outer side of the limiting plate, and a driving cylinder is installed at the end of the mounting plate, the extension end of the driving cylinder is connected to the upper surface of the pressure detection head.

[0009] Preferably, two U-shaped frames are slidably arranged above the support frame, and the two U-shaped frames are symmetrically designed relative to the limiting plate. A fastening plate is fixed to one end of each U-shaped frame, and a rubber pad is installed on the side wall of the fastening plate away from the U-shaped frame. The surface of the rubber pad is provided with multiple friction protrusions, and the fastening plate is located above the limiting plate. During operation, the touch screen panel to be tested is transferred to the top of the two limiting plates by an external robotic arm. Then, the two U-shaped frames are controlled to move simultaneously, so that the two U-shaped frames move closer to each other. The two U-shaped frames will simultaneously drive the fastening plate and the rubber pad to move. Then, the rubber pads on both sides will abut against the sides of the touch screen panel to be tested, thereby achieving the effect of fixing the touch screen panel to be tested. This can avoid the problem of the touch screen panel being tilted during the testing process, which affects the testing efficiency. Moreover, the design of the rubber pads can provide a certain degree of protection for the touch screen panel in the event of breakage, reducing the problem of it scattering.

[0010] Preferably, multiple elastic telescopic rods are provided between the fastening plate and the rubber pad. These elastic telescopic rods are arranged in an array on the side wall of the fastening plate. Springs are sleeved on the outer surface of each elastic telescopic rod. A drive unit is provided on the upper end face of the rotating plate. The drive unit is used to simultaneously drive the limiting plate to rotate and the fastening plate to move. During operation, when the touch screen panel to be tested is transferred above the two limiting plates by an external robotic arm, the two limiting plates are in an skewed state, i.e., not in a horizontal state. When the fastening plate is moved by the drive unit, the drive unit will simultaneously drive the limiting plates from the skewed state to the horizontal state. If the side wall of the rubber pad contacts the side wall of the touch screen panel, and the limiting plates have not yet turned to a horizontal state, the fastening plate will squeeze the elastic telescopic rods and the rubber pad as it continues to move, allowing the elastic telescopic rods and the rubber pad to have sufficient movement margin until the lower limiting plate gradually turns to a horizontal state. This facilitates the pressure resistance testing of touch screen panels of different sizes.

[0011] Preferably, the drive unit includes an L-shaped support rod, which is fixedly installed on the upper surface of the rotating plate. A cylinder seat is installed at the end of the L-shaped support rod away from the rotating plate, and the telescopic end of the cylinder seat is connected to the side wall of the U-shaped frame. During operation, by controlling the telescopic end of the cylinder seat to move, the U-shaped frame can be moved, so that the U-shaped frame can easily drive the fastening plate to move and the limiting plate to rotate.

[0012] Preferably, a rectangular plate is installed at the end of the U-shaped frame away from the fastening plate, and two L-shaped support rods are installed on the side wall of the rectangular plate away from the U-shaped frame. The ends of the two L-shaped support rods are rotatably provided with meshing wheels. The upper surface of the meshing wheels contacts the lower end face of the limiting plate, and a limiting stop is installed at the edge of the lower end face of the limiting plate.

[0013] Preferably, the lower end face of the limiting plate is provided with a rectangular limiting groove, and the meshing wheel is disposed in the rectangular limiting groove. The shape of the meshing wheel is adapted to the shape of the rectangular limiting groove. Two sets of L-shaped support rods and meshing wheels are provided, and they are designed to correspond one-to-one with the two limiting plates. The lower end face edge of the limiting plate is provided with rounded corners. During operation, the rectangular limiting groove is designed so that when the meshing wheel moves at the bottom of the limiting plate, the meshing wheel will move within the rectangular limiting groove. With the two mutually limiting each other, the meshing wheel can be prevented from separating from the bottom of the limiting plate, thus facilitating the rotation of the limiting plate itself.

[0014] Preferably, a connecting frame is installed on the upper surface of the rotating plate, and a limiting ring is installed at the top of the connecting frame. A rotating shaft is rotatably arranged inside the limiting ring, and the limiting plate is rotatably arranged inside the limiting ring via the rotating shaft. During operation, the limiting ring is designed to facilitate the placement of the rotating shaft and the rotation of the limiting plate on the outer surface of the rotating shaft, thereby facilitating the placement of the touch screen panel and the recycling of broken touch screen panels.

[0015] Preferably, a torsion spring is provided at the outer peripheral edge of the rotating shaft, the torsion spring is disposed inside the limiting ring, and the limiting ring has a groove adapted to the torsion spring inside.

[0016] Preferably, the inside of the collection frame is equipped with an inclined plate, and the inside of the collection frame is provided with a guide groove; the inclined plate is designed to facilitate the entry of broken touch screen panels into the guide groove inside the collection frame.

[0017] The beneficial effects of this invention are as follows: 1. The touch screen panel pressure resistance testing device of the present invention uses two U-shaped frames that approach each other, and the two U-shaped frames simultaneously drive the fastening plate and rubber pad to move. Then, the rubber pads on both sides abut against the sides of the touch screen panel to be tested, thereby achieving the effect of fixing the touch screen panel to be tested. This can avoid the problem of the touch screen panel being tilted during the testing process, which affects the testing efficiency. Moreover, the design of the rubber pads can provide a certain degree of protection for the touch screen panel when it is broken, reducing the problem of it shattering.

[0018] 2. The touch screen panel pressure resistance testing device of the present invention, when the limiting plate is in a horizontal state, the torsion spring on the outer surface of the rotating shaft is in a twisted state. When the meshing wheel separates from the bottom of the limiting plate, under the action of the torsion spring, it can quickly drive the limiting plate to rotate closer to the inside of the collection frame. When it contacts the inner wall of the collection frame, the limiting plate will vibrate to a certain extent. In this way, the broken touch screen panels on the surface of the limiting plate can be shaken into the collection frame as soon as possible, avoiding the problem that some touch screen panels stick to the surface of the limiting plate, making it difficult for them to fall into the collection frame.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8 As shown in the figure, a touch screen panel pressure resistance testing device according to an embodiment of the present invention includes a testing platform 1, a rotating plate 2 rotatably disposed above the testing platform 1, the bottom of the rotating plate 2 being connected to the output end of a motor, the motor being installed inside the testing platform 1, a plurality of support frames 3 being installed on the upper surface of the rotating plate 2, each support frame 3 having a touch screen panel to be tested placed on its surface, a limiting plate 4 being rotatably disposed above each support frame 3, and two limiting plates 4 being disposed on the surface of a single support frame 3, a collection frame 201 being installed inside the rotating plate 2, the collection frame 201 being located below the limiting plate 4, an mounting plate 5 being installed on the side wall of the testing platform 1, a pressure detection head 501 being disposed at the end of the mounting plate 5, the pressure detection head 501 being connected to a display screen via a power cord, the display screen being installed above the testing platform 1; It should be noted that a pressure sensor is provided at the end of the pressure detection head 501. When its end contacts the touch screen panel to be tested, the pressure sensor will feed back the pressure to the display screen and display a curve on the display screen. When the touch screen panel is subjected to pressure and breaks, the test is completed. The pressure resistance of the touch screen panel can be observed from the curve on the surface of the display screen. The pressure sensor detection technology here is existing technology and will not be described in detail. When working, refer to the appendix Figure 3 and Figure 4As shown, in the initial state, the two limiting plates 4 are horizontal, and the touch screen panel to be tested is placed on the upper surface of the limiting plate 4. When the touch screen panel needs to be tested for pressure resistance, the control motor drives the rotating plate 2 to rotate. The rotating plate 2 will simultaneously drive the support frame 3 on its upper surface and the touch screen panel to be tested to rotate. When one of the support frames 3 and the touch screen panel to be tested rotates to the bottom of the pressure detection head 501, the rotation of the rotating plate 2 is stopped, and the pressure detection head 501 at the bottom of the mounting plate 5 is controlled to move down, so that the detection end of the pressure detection head 501 contacts the touch screen panel and gradually presses down until it breaks. Then, the pressure resistance of the touch screen panel can be measured by the curve on the surface of the display screen. After the touch screen panel is inspected once, since the limiting plate 4 is rotated and set above the support frame 3, the two limiting plates 4 can be controlled to rotate so that the two limiting plates 4 separate from each other. The broken touch screen panel will then fall along the inclined surface of the limiting plate 4 into the collection box 201 below. This achieves automatic recycling of the broken touch screen panel after inspection, without the need for manual recycling by staff. It is safe and easy to operate.

[0024] Each of the limiting plates 4 has a baffle 6 installed on its upper end face. The baffle 6 is used to cover the outside of the limiting plate 4. A driving cylinder is installed at the end of the mounting plate 5. The extension and retraction end of the driving cylinder is connected to the upper end face of the pressure detection head 501. When working, refer to the appendix Figure 4 As shown, when the two limiting plates 4 are close to each other, the baffle 6 on their upper surface is in a vertical state. After one of the touch screen panels is tested and breaks, the baffle 6 can limit the amount of broken touch screen glass to splash onto the outside of the testing table 1 and prevent the broken touch screen panel from splashing onto the staff. The operation is more convenient. The inclusion of a drive cylinder facilitates the movement of the pressure detection head 501, thereby enabling convenient testing of the touchscreen panel. After one of the touch screen panels has been tested and the two limit plates 4 are far apart, the rotating plate 2 can continue to be controlled to rotate, so that the rotating plate 2 drives the remaining touch screen panels to move, so that the touch screen panels above the remaining support frames 3 move to the bottom of the pressure detection head 501. In this way, the touch screen panels can be continuously tested, which improves the testing efficiency of the touch screen panels.

[0025] Two U-shaped frames 7 are slidably arranged above the support frame 3, and the two U-shaped frames 7 are symmetrically designed with respect to the limiting plate 4; a fastening plate 701 is fixedly connected to one end of the U-shaped frame 7, and a rubber pad 8 is installed on the side wall of the fastening plate 701 away from the U-shaped frame 7. The surface of the rubber pad 8 is provided with multiple friction protrusions, and the fastening plate 701 is located above the limiting plate 4; During operation, an external robotic arm transfers the touchscreen panel to be tested above two limiting plates 4. Then, the two U-shaped frames 7 are moved simultaneously, bringing them closer together. The two U-shaped frames 7 also move the fastening plate 701 and the rubber pad 8. The rubber pads 8 on both sides then press against the sides of the touchscreen panel to be tested, thus fixing the touchscreen panel in place. This prevents the touchscreen panel from tilting during testing, which would affect testing efficiency. In addition, the rubber pads 8 are designed to provide some protection for the touchscreen panel in case of breakage, reducing the risk of it shattering.

[0026] Multiple elastic telescopic rods 9 are provided between the fastening plate 701 and the rubber pad 8. The multiple elastic telescopic rods 9 are arranged in an array on the side wall of the fastening plate 701. Springs are sleeved on the outer surface of the elastic telescopic rods 9. A drive unit is provided on the upper end face of the rotating plate 2. The drive unit is used to simultaneously drive the limiting plate 4 to rotate and the fastening plate 701 to move. During operation, when the touch screen panel to be tested is transferred above the two limiting plates 4 by an external robotic arm, the two limiting plates 4 are in an inclined state, i.e., not in a horizontal state. When the fastening plate 701 is moved by the drive unit, the drive unit will simultaneously drive the limiting plate 4 from the inclined state to the horizontal state. If the side wall of the rubber pad 8 contacts the side wall of the touch screen panel, and the limiting plate 4 has not yet turned to the horizontal state, the fastening plate 701 will squeeze the elastic telescopic rod 9 and the rubber pad 8 as the fastening plate 701 continues to move, so that the elastic telescopic rod 9 and the rubber pad 8 have sufficient movement margin until the lower limiting plate 4 gradually turns to the horizontal state. This facilitates the pressure resistance test of touch screen panels of different sizes.

[0027] The drive unit includes an L-shaped support rod 10, which is fixedly installed on the upper surface of the rotating plate 2. A cylinder seat 11 is installed at the end of the L-shaped support rod 10 away from the rotating plate 2. The telescopic end of the cylinder seat 11 is connected to the side wall of the U-shaped frame 7. During operation, by controlling the telescopic end of the cylinder seat 11 to move, the U-shaped frame 7 can be moved, so that the U-shaped frame 7 can easily drive the fastening plate 701 to move and the limiting plate 4 to rotate.

[0028] A rectangular plate 12 is installed at the end of the U-shaped frame 7 away from the fastening plate 701. Two L-shaped support rods 13 are installed on the side wall of the rectangular plate 12 away from the U-shaped frame 7. The ends of the two L-shaped support rods 13 are rotatably provided with a meshing wheel 14. The upper surface of the meshing wheel 14 contacts the lower end face of the limiting plate 4. A limiting stop 401 is installed at the edge of the lower end face of the limiting plate 4. When working, refer to the appendix Figure 8As shown, when the limiting plate 4 is in a horizontal state, that is, when the ends of the two limiting plates 4 are in contact, the surface of the meshing wheel 14 at the bottom of the limiting plate 4 is in contact with the side wall of the limiting block 401. This indicates that when the meshing wheel 14 moves to contact the limiting block 401, the limiting plate 4 can just rotate to a horizontal state. When the touch screen panel above the limiting plate 4 breaks, the telescopic end of the cylinder seat 11 can be controlled to move, causing the telescopic end to drive the U-shaped frame 7 to move away from the touch screen panel. The U-shaped frame 7 will also drive the rectangular plate 12, the fastening plate 701, the L-shaped support rod 13, and the meshing wheel 14 to move away from the touch screen panel. When the meshing wheel 14 is completely separated from the bottom of the limiting plate 4, the limiting plate 4 will rotate towards the inside of the collection frame 201 under its own weight because the limiting plate 4 is a rotating design. In this way, the broken touch screen panel on the upper surface of the limiting plate 4 will slide down the inclined surface of the limiting plate 4 into the collection frame 201, thus realizing the automatic recycling of the broken touch screen panel.

[0029] The lower end face of the limiting plate 4 is provided with a rectangular limiting groove 15, and the meshing wheel 14 is disposed in the rectangular limiting groove 15. The shape of the meshing wheel 14 is adapted to the shape of the rectangular limiting groove 15. Two sets of L-shaped support rods 13 and meshing wheels 14 are provided, and they are designed to correspond one-to-one with the two limiting plates 4. The lower end face edge of the limiting plate 4 is provided with rounded corners. During operation, a rectangular limiting groove 15 is designed. When the meshing wheel 14 moves at the bottom of the limiting plate 4, the meshing wheel 14 will move within the rectangular limiting groove 15. With the two mutually limiting each other, the meshing wheel 14 can be prevented from separating from the bottom of the limiting plate 4, thus facilitating the rotation of the limiting plate 4 itself. When the broken touch screen panel on the upper surface of the limiting plate 4 slides down the inclined surface of the limiting plate 4 into the collection frame 201, and it is necessary to rotate the limiting plate 4 to a horizontal state again, at this time, it is only necessary to control the telescopic end of the cylinder seat 11 to move, so that its telescopic end drives the U-shaped frame 7 to move. The U-shaped frame 7 will drive the rectangular plate 12, the fastening plate 701, the L-shaped support rod 13 and the meshing wheel 14 to move towards the side closer to the limiting plate 4. Then the meshing wheel 14 will contact the bottom of the limiting plate 4, and the meshing wheel 14 will gradually push the tilted limiting plate 4 to a horizontal state. When the limiting plate 4 is about to be horizontal, the subsequent touch screen panel to be tested can be placed on the limiting plate 4. Then continue to control the movement of the meshing wheel 14 until the meshing wheel 14 contacts the limiting block 401. At this time, the limiting plate 4 is completely horizontal, and the rubber pad 8 on top can fix the touch screen panel.

[0030] A connecting frame 16 is installed on the upper end face of the rotating plate 2. A limiting ring 17 is installed at the top of the connecting frame 16. A rotating shaft 18 is rotatably arranged inside the limiting ring 17. The limiting plate 4 is rotatably arranged inside the limiting ring 17 through the rotating shaft 18. During operation, the limiting ring 17 is designed to facilitate the placement of the rotating shaft 18 and the rotation of the limiting plate 4 on the outer surface of the rotating shaft 18, thereby facilitating the placement of the touch screen panel and the recycling of broken touch screen panels.

[0031] A torsion spring 19 is provided at the outer peripheral edge of the rotating shaft 18. The torsion spring 19 is located inside the limiting ring 17, and the limiting ring 17 has a groove that matches the torsion spring 19. During operation, when the limiting plate 4 is in a horizontal state, the torsion spring 19 on the outer surface of the rotating shaft 18 is in a twisted state. When the meshing wheel 14 separates from the bottom of the limiting plate 4, under the elastic force of the torsion spring 19, it can quickly drive the limiting plate 4 to rotate closer to the inside of the collection frame 201. When it contacts the inner wall of the collection frame 201, the limiting plate 4 will vibrate to a certain extent. This can shake the broken touch screen panels on the surface of the limiting plate 4 into the collection frame 201 as soon as possible, avoiding the problem that some touch screen panels stick to the surface of the limiting plate 4, making it difficult for them to fall into the collection frame 201. This makes it easy to avoid the problem that when the subsequent touch screen panel is placed on the surface of the limiting plate 4, the broken touch screen panel on the surface of the limiting plate 4 prevents the complete touch screen panel from being placed horizontally on the surface of the limiting plate 4.

[0032] An inclined plate 20 is installed inside the collection frame 201, and a guide groove is provided inside the collection frame 201; the inclined plate 20 is designed to facilitate the entry of broken touch screen panels into the guide groove inside the collection frame 201.

[0033] When working, refer to the appendix Figure 3 and Figure 4 As shown, in the initial state, the two limiting plates 4 are horizontal, and the touch screen panel to be tested is placed on the upper surface of the limiting plate 4. When the touch screen panel needs to be tested for pressure resistance, the control motor drives the rotating plate 2 to rotate. The rotating plate 2 will simultaneously drive the support frame 3 on its upper surface and the touch screen panel to be tested to rotate. When one of the support frames 3 and the touch screen panel to be tested rotates to the bottom of the pressure detection head 501, the rotation of the rotating plate 2 is stopped, and the pressure detection head 501 at the bottom of the mounting plate 5 is controlled to move down, so that the detection end of the pressure detection head 501 contacts the touch screen panel and gradually presses down until it breaks. Then, the pressure resistance of the touch screen panel can be measured by the curve on the surface of the display screen. After the touchscreen panel is inspected once, since the limiting plate 4 is rotatably positioned above the support frame 3, the two limiting plates 4 can be controlled to rotate, causing them to separate. The broken touchscreen panel will then fall along the inclined surface of the limiting plate 4 into the collection box 201 below. This achieves automatic recycling of the inspected broken touchscreen panel, eliminating the need for manual recycling, ensuring high safety, and providing convenient operation. (See attached...) Figure 4 As shown, when the two limiting plates 4 are close to each other, the baffle 6 on their upper surface is in a vertical state. After one of the touch screen panels is tested and breaks, the baffle 6 can limit the amount of broken touch screen glass to splash onto the outside of the testing table 1 and prevent the broken touch screen panel from splashing onto the staff. The operation is more convenient. An external robotic arm transfers the touchscreen panel to be inspected above two limiting plates 4. Then, two U-shaped brackets 7 are moved simultaneously, bringing them closer together. These brackets also move the fastening plate 701 and rubber pads 8. The rubber pads 8 then press against the sides of the touchscreen panel to secure it, preventing tilting during inspection and improving efficiency. Furthermore, the rubber pads 8 provide some protection in case of breakage, reducing the risk of sharding. The external robotic arm then transfers the touchscreen panel to... When the device moves above the two limiting plates 4, the two limiting plates 4 are in an inclined state, that is, not in a horizontal state. When the fastening plate 701 is moved by the drive unit, the drive unit will simultaneously drive the limiting plate 4 from the inclined state to the horizontal state. If the side wall of the rubber pad 8 contacts the side wall of the touch screen panel, and the limiting plate 4 has not yet turned to the horizontal state, the fastening plate 701 will squeeze the elastic telescopic rod 9 and the rubber pad 8 as the fastening plate 701 continues to move, so that the elastic telescopic rod 9 and the rubber pad 8 have enough room for movement until the lower limiting plate 4 gradually turns to the horizontal state. This makes it convenient to perform pressure resistance testing on touch screen panels of different sizes. See attached document Figure 8 As shown, when the limiting plate 4 is in a horizontal state, that is, when the ends of the two limiting plates 4 are in contact, the surface of the meshing wheel 14 at the bottom of the limiting plate 4 is in contact with the side wall of the limiting block 401. This indicates that when the meshing wheel 14 moves to contact the limiting block 401, the limiting plate 4 can just rotate to a horizontal state. When the touchscreen panel above the limiting plate 4 breaks, the telescopic end of the cylinder seat 11 can be moved, causing the telescopic end to drive the U-shaped frame 7 to move away from the touchscreen panel. Simultaneously, the U-shaped frame 7 will drive the rectangular plate 12, the fastening plate 701, the L-shaped support rod 13, and the meshing wheel 14 to move away from the touchscreen panel. When the meshing wheel 14 completely separates from the bottom of the limiting plate 4, due to the rotating design of the limiting plate 4, it will move towards the bottom under its own weight. The internal rotation of the near-collection frame 201 causes the broken touch screen panel on the upper surface of the limiting plate 4 to slide down the inclined surface of the limiting plate 4 into the collection frame 201, thus enabling automatic recycling of the broken touch screen panel. A rectangular limiting groove 15 is designed so that when the meshing wheel 14 moves at the bottom of the limiting plate 4, the meshing wheel 14 will move within the rectangular limiting groove 15. With the two mutually limiting each other, the meshing wheel 14 can be prevented from separating from the bottom of the limiting plate 4, thus facilitating the rotation of the limiting plate 4 itself. When the broken touchscreen panel on the upper surface of the limiting plate 4 slides down the inclined surface of the limiting plate 4 into the collection frame 201, and it is necessary to rotate the limiting plate 4 back to a horizontal state, simply control the telescopic end of the cylinder seat 11 to move, causing its telescopic end to drive the U-shaped frame 7 to move. The U-shaped frame 7 will drive the rectangular plate 12, the fastening plate 701, the L-shaped support rod 13, and the meshing wheel 14 to move towards the side closer to the limiting plate 4. Then, the meshing wheel 14 will contact the bottom of the limiting plate 4, and the meshing wheel 14 will gradually push the tilted limiting plate 4 to a horizontal state. When the limiting plate 4 is about to reach a horizontal state, the subsequent touchscreen panel to be tested can be placed on top of the limiting plate 4, and then the meshing wheel 14 can be moved again. The engagement wheel 14 contacts the limiting block 401, at which point the limiting plate 4 is completely horizontal, and the rubber pad 8 above it can fix the touch screen panel. When the limiting plate 4 is horizontal, the torsion spring 19 on the outer surface of the rotating shaft 18 is in a twisted state. When the engagement wheel 14 separates from the bottom of the limiting plate 4, under the elastic force of the torsion spring 19, it can quickly drive the limiting plate 4 to rotate closer to the inside of the collection frame 201. When it contacts the inner wall of the collection frame 201, the limiting plate 4 will vibrate to a certain extent. This can shake the broken touch screen panel on the surface of the limiting plate 4 into the collection frame 201 as soon as possible, avoiding the problem that some touch screen panels stick to the surface of the limiting plate 4, making it difficult for them to fall into the collection frame 201.
