[0041] The upper side and the lower side of the through slot 601 of the limiting rod 6 are both configured as arc surfaces, so as to facilitate the movement and bending of the supporting plate 7 and avoid additional damage to the flexible touch screen during the bending process.
[0042] The arc-shaped slide rail 121 is set to a U shape, and the limiting rod 6 is located in the middle thereof. When the flexible touch screen is subjected to bending detection, the electric slider 122 can drive the supporting plate 7 to bend upward and downward, thereby respectively detecting the bending of the front and back sides of the flexible touch screen, making the bending performance detection more comprehensive.

[0045] In the process of testing the anti-extrusion performance of the flexible touch screen, firstly, the left and right micro motors 75 are controlled simultaneously to drive the winding roller 74 to rotate, and the winding roller 74 rotates the winding rope 73. Since the rope 73 is in a U shape and passes through all the supporting sheets 72, as shown in FIG. Figure 8As shown, the right winding roller 74 winds up the right pull rope 73, and the right pull rope 73 drives the leftmost supporting piece 72 to move rightward, and the leftmost supporting piece 72 drives other supporting pieces 72 to move rightward along the connecting rod 71. Correspondingly, the left winding roller 74 is controlled to wind up the left pull rope 73, and the left pull rope 73 drives the rightmost supporting piece 72 to move leftward. By moving the leftmost supporting piece 72 to the right and the rightmost supporting piece 72 to the left, the two move toward each other, thereby driving all the supporting pieces 72 to slide on the connecting rod 71 and move closer to each other. As the pull rope 73 is tightened, all the supporting sheets 72 move and fit closely together. Then, the winding roller 74 tightens the pull rope 73 and controls the micro motor 75 to stop working. Under the tightening of the pull rope 73, all the supporting sheets 72 together form a complete supporting plate 7. In addition, in the process of tightening the pull rope 73, the two moving blocks 32 are simultaneously controlled to drive the corresponding mounting plate 3, linear slide rail 4, electric slider 5, limiting rod 6 and other connected parts to move toward each other, so that in the process of the supporting sheets 72 moving and fitting together, the supporting plate 7 is always supported on the through groove 601 of the two limiting rods 6.
[0046] Then, the flexible touch screen to be tested is manually placed on the supporting plate 7, and the flexible touch screen placed on the surface of the supporting plate 7 is adsorbed and fixed by controlling the suction cup 8, and then the moving block 1 22 is controlled to drive the electric telescopic rod 23, the rotating motor 24, the guide rail 25, the moving block 26 and the electric control pressing head 2 to move left and right along the guide rail 1 21, and the electric telescopic rod 23 is controlled to drive the guide rail 2 25, the moving block 26 and the electric control pressing head 2 to move up and down, and at the same time, the moving block 26 is controlled to drive the electric control pressing head 2 to move forward and backward along the guide rail 25. Through their mutual cooperation, the electric control pressing head 2 can be driven to perform anti-extrusion detection on various parts of the flexible touch screen fixed on the surface of the supporting plate 7; and in the process of testing the pit extrusion performance of the flexible touch screen, the two electric sliders 1 5 on the left are controlled to drive the limiting rod 6 to move upward along the corresponding linear slide rail 4, and the limiting rod 6 drives the left end of the supporting plate 7 to move upward, so that The supporting plate 7 is transformed into an inclined state with the left end higher and the right end lower, thereby driving the fixed flexible touch screen to rotate and tilt. During the rotation of the supporting plate 7, the micro motor 75 is controlled to drive the winding roller 74 to rotate slowly, releasing the pull rope 73, so that the supporting plate 7 can be driven by the limiting rod 6 to rotate upward. When the rotation of the inclination angle of the supporting plate 7 is completed, the micro motor 75 is controlled to drive the winding roller 74 to rewind the pull rope 73, and the pull rope 73 is tightened to ensure the stability of the supporting plate 7. Subsequently, the flexible touch screen is tested for anti-extrusion through the electrically controlled pressing head 2. At the same time, by controlling the two electric sliders 5 on the front or rear side to move upward with the limiting rod 6, the front or rear side of the supporting plate 7 is driven to rotate and tilt upward, so that the flexible touch screen can be tilted in different directions and at different angles, and then the flexible touch screen can be pressed in different directions and at different angles, thereby improving the diversity of anti-extrusion detection of the flexible touch screen and making the detection results richer.
[0047] Moreover, during the test of the anti-extrusion of the flexible touch screen, the electric push rod 101 is controlled to drive the pressing rod 102 to extend, and then the flexible touch screen is pressed by the pressing rod 102, thereby simulating the extrusion test of the flexible touch screen by a sharp object, so that the result of the anti-extrusion test of the flexible touch screen is more reliable; and during the test of the pressure applied by the electric-controlled pressing head 2 and the pressing rod 102 to the flexible touch screen, the pressure applied by the pressure sensor arranged on the electric-controlled pressing head 2 is recorded, thereby obtaining the anti-extrusion performance of the flexible touch screen.
[0048] After the anti-extrusion performance test of the flexible touch screen is completed, considering that the flexible touch screen has the characteristics of twisting and bending, the flexible touch screen will be used in a twisted shape in special occasions, and the flexible touch screen also needs to be tested for its torsion performance after production; therefore, after the anti-extrusion performance test of the flat state of the flexible touch screen is completed, the relevant parts are first controlled to move and reset so that the supporting plate 7 remains flat, and then the flexible touch screen after the anti-extrusion test is manually removed, and another new flexible touch screen is placed on the supporting plate 7, so that the left and right ends of the flexible touch screen are both located under the corresponding pressing plate 112, and then the electric push rod 111 is controlled to drive the pressing plate 112 to move, and the pressing plate 112 moves to press the end of the left side of the supporting plate 7 The supporting pieces 72 at the left and right ends, as well as the two ends of the flexible touch screen, are pressed together on the through slot 601 of the limiting rod 6, and then the moving blocks three 32 on the left and the moving blocks three 32 on the right are controlled to drive the mounting plate 3 and the limiting rod 6 to move opposite to each other, and at the same time, the winding roller 74 is controlled to release the pull rope 73, and the limiting rod 6 clamps the supporting pieces 72 at the left and right ends of the supporting plate 7 to move opposite to each other, stretching the supporting plate 7 and at the same time stretching and tightening the fixed flexible touch screen. It should be noted that during this process, the suction cup 8 does not adsorb and fix the flexible touch screen placed on the surface of the supporting plate 7, and then the electric slider 5 in front of the right mounting plate 3 is controlled to drive the front end of the limiting rod 6 to move upward, and the electric slider 5 behind the right mounting plate 3 is controlled to drive the rear end of the limiting rod 6 to move forward The electric slider 5 at the rear of the left mounting plate 3 is controlled to move downward, and the electric slider 5 at the front of the left mounting plate 3 is controlled to drive the front end of the other limiting rod 6 to move downward, and the electric slider 5 at the rear of the left mounting plate 3 is controlled to drive the rear end of the other limiting rod 6 to move upward. At this time, the two limiting rods 6 rotate in opposite directions, and the rotation of the limiting rod 6 drives the left and right ends of the supporting plate 7 to rotate and twist in opposite directions, thereby driving the flexible touch screen fixed on the supporting plate 7 to twist, thereby simulating the torsional performance of the flexible touch screen. At the same time, the same operation is performed as above, controlling the electric slider 5 in front of the right mounting plate 3 to move downward, the electric slider 5 at the rear of the right mounting plate 3 to move downward, and controlling the electric slider 5 in front of the left mounting plate 3 to move upward. The electric slider 113 at the rear side moves downward, and the electric slider 113 moves in the opposite direction, driving the two limiting rods 6 to rotate in the opposite direction, so that the flexible touch screen can be twisted in different directions, and the twisting performance of the flexible touch screen can be fully tested; and in the twisting detection process, the linear slide 4 is driven to rotate by controlling the driving motor 113, so that the linear slide 4 is changed from a vertical state to an inclined state, thereby changing the movement trajectory of the electric slider 113. When the electric slider 113 is controlled to move again, the electric slider 113 drives the limiting rod 6 to change its rotation angle, thereby causing the limiting rod 6 to drive the flexible touch screen to twist with a change in amplitude, so that the flexible touch screen can also be twisted with different amplitudes, further improving the comprehensiveness of the twisting performance detection of the flexible touch screen;Moreover, after the supporting plate 7 drives the flexible touch screen to twist together, the micro motor 75 is then controlled to drive the winding roller 74 to rotate the winding rope 73, so that the rope 73 is taut, and the twisted supporting sheet 72 is tightened. At this time, the twisted flexible touch screen is supported by the twisted supporting plate 7, and then the flexible touch screen is pressed by controlling the electric control pressing head 2 to move and press the flexible touch screen, and the anti-extrusion test of the twisted flexible touch screen is performed, thereby improving the diversity of the anti-extrusion test of the flexible touch screen. ;
[0049] In addition, flexible touch screens are often used in a bent state, such as folding screens, so the bending performance of the flexible touch screen also needs to be tested. After the torsional performance of the flexible touch screen is tested, the corresponding parts are then controlled to move so that the support plate 7 remains straight again, and then the electric push rod 2 111 on the right limiting rod 6 is controlled to drive the pressing plate 112 to move upward, and the fixation of the right side of the support plate 7 and the right side of the flexible touch screen is stopped. Then, the moving block 3 32 is controlled to drive the mounting plate 3 and the limiting rod 6 on the right side to move to the left, and at the same time, the electric slider 2 122 on the right side is controlled to drive the retracting The winding roller 74 and the pull rope 73 move clockwise along the arc-shaped slide rail 121 when viewed from the front to the back, and the winding roller 74 and the pull rope 73 drive the supporting plate 72 to rotate around the arc surface on the lower side of the through groove 601, so that the supporting plate 7 is bent around the arc surface on the lower side of the through groove 601, thereby driving the flexible touch screen to bend, thereby simulating and testing the bending performance of the flexible touch screen; and, after the flexible touch screen is bent, the micro motor 75 is then controlled to drive the winding roller 74 to rotate and tighten the pull rope 73, and the pull rope 73 tightens the supporting plate 7. At this time, the bent flexible touch screen is supported by the bent supporting plate 7. Then, the moving block 1 22 and the moving block 2 26 are controlled to cooperate with each other to drive the electric control pressing head 2 to move between the arc-shaped slide rail 121 and the flexible touch screen, and the electric control pressing head 2 is used to perform anti-extrusion detection on the flexible touch screen after bending, and facing the bent part of the flexible touch screen, the rotating motor 24 is controlled to drive the guide rail 2 25, the moving block 2 26 and the electric control pressing head 2 to rotate, so that the electric control pressing head 2 can also perform anti-compression detection on the bent part of the flexible touch screen, making the pit extrusion performance detection of the flexible touch screen more comprehensive; at the same time, the arc-shaped slide rail 121 is set to a U shape, when the electric control pressing head 2 is After the movable slider 122 moves clockwise along the arc-shaped slide rail 121 to complete the bending test of the flexible touch screen, it is then controlled to reset, and the electric slider 122 is controlled again to move counterclockwise along the arc-shaped slide rail 121 from the front to the back, thereby driving the flexible touch screen to bend upward around the arc surface on the upper side of the through groove 601, so that when the bending test of the flexible touch screen is performed, the electric slider 122 can simultaneously drive the flexible touch screen to bend upward and downward, thereby respectively detecting the bending of the front and back sides of the flexible touch screen, making the bending performance test more comprehensive.

[0052] The end of the top plate 202 is made of silicone material to avoid causing additional damage to the flexible touch screen and affecting the detection result during the process of the top plate 202 pushing the flexible touch screen.
[0053] A method for using an anti-extrusion performance testing device that can adapt to a flexible touch screen includes the following steps:
[0054] Step 1: Placement work, first control the winding rollers 74 on both sides to rotate the winding rope 73, so that all the supporting sheets 72 together form a complete supporting plate 7 under the tightening of the rope 73, and then manually place the flexible touch screen on the supporting plate 7;
[0055] Step 2: Testing work, controlling the electronically controlled pressing head 2 to move and press the flexible touch screen to test its anti-extrusion performance; at the same time, by driving the front or rear side of the supporting plate 7 to rotate and tilt upward, the flexible touch screen can be tilted in different directions and angles, and then the flexible touch screen can be pressed in different directions and angles, thereby improving the diversity of the anti-extrusion detection of the flexible touch screen;
[0056] Step 3: Torsion detection work, manually replace the new flexible touch screen, and drive the left and right ends of the supporting plate 7 to rotate and twist in opposite directions by controlling the limiting rod 6 to rotate, thereby driving the flexible touch screen fixed on the supporting plate 7 to twist, thereby simulating the detection of the torsion performance of the flexible touch screen;
[0057] Step 4: Bending detection work, by driving the supporting plate 72 to rotate around the arc surface on the lower side of the through groove 601, the supporting plate 7 is bent around the arc surface on the lower side of the through groove 601, and then the flexible touch screen is driven to bend, thereby simulating the bending performance of the flexible touch screen.
[0058] On the basis of the above-mentioned embodiment 1, when the electric slider 2 122 drives the supporting plate 7 to bend around the lower side of the through groove 601 or the upper side of the through groove 601 of the limiting rod 6, when the flexible touch screen bends around the arc surface on its upper side or the lower side, its bending angle is always the same, while the bending angles of the flexible touch screen are different during actual use, which makes the bending detection of the flexible touch screen have certain limitations; therefore, after the supporting plate 7 is bent around the arc surface on the lower side of the through groove 601 or the arc surface on the upper side of the through groove 601, the electric push rod 3 201 is then controlled to drive the top plate 202 to extend from the arc surface, lift up the bent supporting plate 7 and the flexible touch screen, so that the bending angle of the flexible touch screen is reduced, and the bending angle of the flexible touch screen is adjusted by the length of the extended top plate 202, so that the flexible touch screen can be bent at different angles, thereby increasing the diversity of the bending detection of the flexible touch screen and ensuring the reliability of the detection result.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
