[0046] The working steps of the above embodiment are: first, the staff puts the LCD display screen 100 into the fixing frame II 101. During the process of putting the LCD display screen 100 in, the LCD display screen 100 will squeeze the clamping plate II 105, so that the spring rod connected to the clamping plate II 105 is compressed, thereby pushing the LCD display screen 100 to be close to the sliding bar 106 and the fixing bar 107 through the reset force of the spring rod, thereby limiting the position of the LCD display screen 100, and then controlling the electric push rod 102 to pull the clamping plate I 103 to move in the direction close to the LCD display screen 100, thereby clamping and fixing the LCD display screen 100, so that when the durability test is performed on the interface of the LCD display screen 100 later, the LCD display screen 100 will not move, so as to avoid affecting the durability test of the interface of the LCD display screen 100; then the staff inserts the positioning rod I 2 and the positioning rod II 3 into the corresponding interfaces on the LCD display screen 100 respectively, and then drives the fixing frame II 101 and the LCD display screen 100 through the motor II 104. 00 From the left perspective, rotate counterclockwise 90 degrees so that the positioning rods Ⅰ2 and Ⅱ3 face the direction of the wiring board 7, which is convenient for the subsequent positioning of the interface of the LCD display screen 100, and avoids the wiring board 7 from being difficult to be completely aligned with the interface of the LCD display screen 100 due to the interface of part of the LCD display screen 100 being in the groove; then control the pneumatic push rod 205 to push the fixed frame Ⅰ4 and the rotating plate 5 and all the parts connected to them to move forward, and when the lateral position of the wiring board 7 is aligned with the positioning grooves 2002 on the positioning rods Ⅰ2 and Ⅱ3, the pneumatic push rod 205 stops pushing the fixed frame Ⅰ4 and the rotating plate 5 to move, and then control the slider Ⅰ202 to drive the slide rail Ⅱ203 and the slider Ⅱ204 and all the parts connected to them to move up and down, when the infrared receivers arranged on the positioning rods Ⅰ2 and Ⅱ3 detect the signal generated by the infrared transmitter on the clamping block 9, it means that the wiring board 7 is at the same height as the positioning grooves 2002 on the positioning rods Ⅰ2 and Ⅱ3, and then the slider Ⅰ202 stops moving;Then the slider II 204 is controlled to drive the pneumatic push rod 205, the fixing frame I4, the rotating plate 5 and all the parts connected thereto to move along the slide rail II 203. When the infrared receivers arranged on the positioning rods I2 and II3 on ​​the plugboard 7 detect the signal generated by the infrared transmitter on the rotating plate 5, it means that the plugboard 7 enters the positioning groove 2002 on the positioning rods I2 and II3. Then the slider II 204 stops moving. Since the positioning rods I2 and II3 are respectively inserted into different interfaces of the LCD display screen 100, the interfaces of the plugboard 7 and the LCD display screen 100 will be completely aligned at this time, which is convenient for the subsequent durability test of the interface of the LCD display screen 100. The present invention can automatically and quickly align the plugboard 7 with the positioning rods I2 and II3, so as to adapt to LCD display screens 100 with different interface positions, thereby avoiding the problem of low efficiency caused by taking a long time to completely align the port of the connecting line with the interface of the LCD display screen 100 when performing durability test on different interfaces of the LCD display screen 100 in the prior art. ;

[0047] Then the pneumatic push rod 205 is controlled to pull the fixed frame Ⅰ4 and the rotating plate 5 to move backward. When the plug board 7 is no longer in the positioning rod Ⅰ2 and the positioning rod Ⅱ3, and there is enough space for the rotating plate 5 to rotate, the pneumatic push rod 205 stops pulling the fixed frame Ⅰ4 and the rotating plate 5 to move, and then the motor Ⅰ6 is controlled to drive the rotating plate 5 to rotate. When the rotating plate 5 rotates until the electromagnet 10 is aligned with the positioning rod Ⅰ2 and the positioning rod Ⅱ3, the motor Ⅰ6 stops rotating, and then the pneumatic push rod 205 is controlled again to push the fixed frame Ⅰ4 and the rotating plate 5 to move forward. At this time, the electromagnet 10 is aligned with the positioning rod Ⅰ2 and the positioning rod Ⅱ3. Therefore, after the electromagnet 10 moves forward, the positioning rod Ⅰ2 and the positioning rod Ⅱ3 will enter the electromagnetic The electromagnet 10 is then controlled to start, so that the electromagnet 10 attracts the positioning rod Ⅰ2 and the positioning rod Ⅱ3, and then the pneumatic push rod 205 is controlled to pull the fixing frame Ⅰ4 and the rotating plate 5 to move backward. Since the electromagnet 10 attracts the positioning rod Ⅰ2 and the positioning rod Ⅱ3 at this time, the electromagnet 10 will pull the positioning rod Ⅰ2 to move backward, and pull the positioning rod Ⅰ2 and the positioning rod Ⅱ3 out of the interface of the LCD display screen 100, so as to prevent the positioning rod Ⅰ2 from blocking the durability test of the interface of the LCD display screen 100; and then the motor Ⅰ6 is controlled to drive the rotating plate 5 to rotate and reset. When the plug board 7 rotates to align with the interface of the LCD display screen 100 again, the motor Ⅰ6 is controlled to stop rotating. At this time, it is as follows Fig.10In the state shown, the pneumatic push rod 205 is then controlled to repeatedly push the fixing frame Ⅰ4 and the rotating plate 5 to move back and forth repeatedly, so that the socket board 7 moves back and forth repeatedly, so that the socket board 7 begins to be repeatedly plugged and unplugged in the interface of the LCD display screen 100, and then the durability of the interface of the LCD display screen 100 is detected; because some LCD display screens 100 will be used in an environment with a lot of dust, when the LCD display screen 100 is replaced in an environment with a lot of dust, dust enters between the connecting wire and the interface, which will make it difficult to insert or unplug the connecting wire from the interface. Therefore, in the process of repeated plugging and unplugging of the socket board 7, dust is input into the jet bar 302 through the dust conveying device connected to the jet bar 302, so that dust begins to be ejected from the jet port of the jet bar 302, thereby simulating the socket board 7 being in an environment with a lot of dust, and then the influence of the environment with a lot of dust on the plugging and unplugging performance of the interface of the LCD display screen 100 is detected.

[0048] When dust starts to be ejected from the jet port of the jet bar 302, the fan I 304 is controlled to start, so as to suck the dust ejected from the jet bar 302 into the storage frame 301 to prevent the dust from spreading, and input clean water into the storage frame 301 through the pump connected to the storage frame 301, and then during the process of repeatedly plugging and unplugging the power strip 7 in the interface of the LCD display screen 100, the positioning rod I 2 and the positioning rod II 3 will repeatedly move back and forth in the avoidance groove 30101. Since a magnet portion is provided in the middle of the positioning rod I 2 and the positioning rod II 3, and the sliding rod 501 is set to a magnetic material, the positioning rod I 2 and the positioning rod II 3 will drive the sliding rod 501 and the stirring plate 502 to move back and forth repeatedly during the repeated forward and backward movement, so that the clean water and dust are evenly mixed by the stirring plate 502 to form sewage; then the sewage in the storage frame 301 is pumped out by the pump, and the pumped out sewage is transported to the fixed bar 107 by the pump, and then through The water is atomized and then sprayed out through the water spray port II 10701, and then during the interface durability test of the LCD display screen 100, after the water evaporates, a large amount of dust quickly adheres to the LCD display screen 100, thereby simulating the situation where a large amount of dust adheres to the LCD display screen 100, and when the durability test of the interface of the LCD display screen 100 is about to be completed, another pump is controlled to input clean water into the sliding bar 106, and then the water is atomized and then sprayed out through the water spray port I 10601, thereby simulating the situation where the LCD display screen 100 is in a humid environment; since some LCD display screens 100 will be used in a humid or dusty environment, when dust or water adheres to the LCD display screen 100, it will affect the touch screen function of the LCD display screen 100, and by simulating an environment with a large amount of dust and humidity on the LCD display screen 100, it is convenient for the subsequent detection of the touch screen function of the LCD display screen 100.

[0049] When the durability test of the interface of the LCD display screen 100 is completed, the bidirectional pneumatic push rod 8 is controlled to push the clamping block 9 to move away, so that the clamping block 9 no longer clamps the power strip 7, so that when the LCD display screen 100 rotates subsequently, the LCD display screen 100 will drive the power strip 7 to rotate together, so as to avoid the LCD display screen 100 being unable to power on after the rotation; then the motor Ⅱ 104 is controlled to drive the fixing frame Ⅱ 101 and all the parts connected to it to rotate ninety degrees clockwise from a left perspective, and the fixing frame Ⅱ 101 drives the LCD display screen 100 to rotate, so that the front of the LCD display screen 100 faces the power strip 7, and then the motor Ⅰ 6 drives the rotating plate 5, the power strip 7 and all the parts connected to it to rotate upward by ninety degrees, so that the positioning rod Ⅰ 2 and the positioning rod Ⅱ 3 face the front of the LCD display screen 100, and then the pneumatic push rod 205 is controlled to push the electromagnet 10 and the positioning rod Ⅰ 2 to move forward, when the touch block 2001 and When the sliding block 3001 contacts the LCD display screen 100, the pneumatic push rod 205 stops pushing, and then controls the slider Ⅰ202 or the slider Ⅱ204 to drive the positioning rod Ⅰ2 and the positioning rod Ⅱ3 to move, so that the touch block 2001 slides on the LCD display screen 100, thereby detecting the response speed and accuracy of the touch screen function of the LCD display screen 100; and the anti-scratch performance of the LCD display screen 100 is detected by the sliding block 3001; it is further noted that when the positioning rod Ⅰ2 moves to the water spray bar, the pneumatic push rod 205 is controlled to pull the positioning rod Ⅰ2 to move backward to avoid the water spray bar, and then after passing the water spray bar, the pneumatic push rod 205 is controlled to push the positioning rod Ⅰ2 to move forward until it contacts the LCD display screen 100 again; and by simulating an environment with a lot of dust and humidity on the LCD display screen 100, the influence of water or dust attached to the LCD display screen 100 on the touch screen function is further detected.

[0050] When the touch screen function test is completed, the motor II 104 is used again to drive the fixing frame II 101 and the LCD display screen 100 to rotate counterclockwise by 90 degrees from the left viewing angle, so that the front of the LCD display screen 100 faces upward again, and then the pump connected to the sliding bar 106 is used to input clean water into the sliding bar 106 again, and the electric control valve provided at the water spray port III 10602 is controlled to open, so that the water spray port III 10602 is connected with the internal space of the sliding bar 106, so that clean water can be sprayed out from the water spray port III 10602, and then the clean water is sprayed out through the water spray port I 10601 and the water spray port III 10602, thereby leaving a layer of clean water on the LCD display screen 100, and then it is tested whether the clean water can enter the interior of the LCD display screen 100 and whether it can operate normally, thereby testing the waterproof performance of the LCD display screen 100. And soak the adhered dust to facilitate subsequent cleaning, then control motor II 104 again to drive fixing frame II 101 and LCD display screen 100 to rotate counterclockwise forty-five degrees from a left viewing angle, so that the end of the LCD display screen 100 with the interface faces upward to prevent the clean water on the LCD display screen 100 from flowing into the interface of the LCD display screen 100 after tilting, affecting the subsequent use of the LCD display screen 100, and then the clean water on the LCD display screen 100 flows downward along the LCD display screen 100 to the leakage groove on the fixing frame II 101, and then flows into the water storage tank 1001 to prevent the outflowing clean water from spreading, and then the staff can pull the sliding bar 106 to move left and right, so as to clean the LCD display screen 100 through the sponge layer set on the sliding bar 106 to remove the dust adhered to the LCD display screen 100.

[0051] When the detection is completed, the control motor II 104 drives the fixing frame II 101 and the LCD display screen 100 to reset, and then controls the electric push rod 102 to push the clamping plate I 103 to move away from the LCD display screen 100, so that the clamping plate I 103 no longer clamps the LCD display screen 100, and then the staff unplugs the plug board 7 from the interface of the LCD display screen 100, and then pulls the plug board 7 to reset through the winding device connected to the plug board 7, and then pulls the clamping block 9 to move toward each other through the bidirectional pneumatic push rod 8, so as to re-plug the plug board The plate 7 is clamped and fixed, and then the staff takes out the LCD display screen 100 from the fixing frame Ⅱ101, and then places a new LCD display screen 100 on the fixing frame Ⅱ101, and clamps and fixes it through the clamping plate Ⅰ103, and then controls the electromagnet 10 to be closed, so that the electromagnet 10 no longer attracts the positioning rod Ⅰ2 and the positioning rod Ⅱ3, and then the staff pulls out the positioning rod Ⅰ2 and the positioning rod Ⅱ3 from the electromagnet 10, and inserts them into the newly placed LCD display screen 100 for positioning, and repeats this process to test the LCD display screen 100.

[0052] Example 2

[0053] On the basis of Example 1, Figure 3 and Figure 4 As shown, the positioning rod Ⅰ2 and the positioning rod Ⅱ3 are both configured as elastic telescopic rods.

[0054] The working steps of the above embodiment are as follows: since part of the LCD display screen 100 is a curved screen, the positioning rod Ⅰ2 makes it impossible for the positioning rod Ⅰ2 and the positioning rod Ⅱ3 to complete the contact with the curved LCD display screen 100 when the positioning rod Ⅰ2 slides on the LCD display screen 100, resulting in the inability to detect the touch screen function of the curved LCD display screen 100. When the pneumatic push rod 205 pushes the positioning rod Ⅰ2 and the positioning rod Ⅱ3 to move forward, after the positioning rod Ⅰ2 and the positioning rod Ⅱ3 are connected with the LCD display screen 100, the pneumatic push rod 205 is controlled to push a certain distance, so that the positioning rod Ⅰ2 and the positioning rod Ⅱ3 are compressed, so that the positioning rod Ⅰ2 and the positioning rod Ⅱ3 are in contact with each other. When positioning rod Ⅰ2 and positioning rod Ⅱ3 slide to the concave part of the curved surface of LCD display screen 100, the spring rod inside positioning rod Ⅰ2 and positioning rod Ⅱ3 will push the corresponding touch block 2001 or sliding block 3001 to move forward to contact with LCD display screen 100. When sliding to the convex part of the curved surface of LCD display screen 100, positioning rod Ⅰ2 and positioning rod Ⅱ3 will be further compressed, so that positioning rod Ⅰ2 and positioning rod Ⅱ3 can always fit with the curved surface of LCD display screen 100, avoiding the situation that positioning rod Ⅰ2 and positioning rod Ⅱ3 cannot complete the contact with the curved surface of LCD display screen 100, resulting in the inability to detect the touch screen function of the curved surface of LCD display screen 100.

[0055] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
