Description

Technical Field

[0001] The invention relates to the technical field of display detection, in particular to a TFT display screen compression resistance detection device. Background Art

[0002] TFT display is a type of flat panel display, used for TV and computer screen display. Liquid crystal display uses a liquid crystal solution in two polarized materials, so that when current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging. Liquid crystal display needs to be tested for its own strength during production.

[0003] In order to improve the quality of display screens during production, it is necessary to test the pressure resistance of display screens. When a traditional pressure resistance testing device detects a display screen with poor pressure resistance, the equipment in the testing process cannot perform testing and cleaning at the same time, which not only delays the testing of the next display screen, but also fails to clean up in time. Dust or glass debris generated by unqualified equipment causes the display screen to break and cause fragments to splash, which not only increases the difficulty of subsequent cleaning, but also makes it easy for the debris to splash during the breaking process. If the dust and debris accumulated on the workbench are not cleaned up in time, it is easy to affect the internal components. Therefore, a TFT display screen pressure resistance testing device is proposed. Summary of the invention

At this time, an infrared sensing device is provided at the bottom of the connecting long rod at the corresponding position of the other end. When the infrared sensing device senses that the vacant placement slot where the detection is completed is located below, the detection and cleaning can be performed simultaneously. Since the driving motor of the auxiliary detection device inside the rotating table is electrically connected to the infrared sensing device, the outer wall of the second driving motor is provided with a limit groove, and the outer wall is connected with a telescopic rod.

When the detected equipment is moved out of the placement slot, since the electric dust suction pump is electrically connected to the first drive motor, when the motor is started, the dust suction component starts to operate, and the impurities after dust removal enter the dust suction branch pipe from the main pipe, and then are transmitted to the collection box by the conveying pipe. The collected dust can be removed by pulling the collection box, which effectively avoids the difficulty of subsequent cleaning and the damage of internal components caused by failure to remove impurities in time, which may easily cause inaccurate detection results.

[0031] Working principle: when the device needs to be used, start the control switch 4 and put the display screen to be tested into the placement groove 103.

When the first drive motor 102 starts to run, the sliding column 74 slides on the guide rod 72. Since one end of the sliding column 74 is connected to the connecting long rod 8 through the first connecting plate 76, when the connecting long rod 8 moves up and down in the sliding groove 62, the sliding column 74 effectively assists the connecting long rod 8 to reduce the shaking of the equipment. The inner wall of the connecting long rod 8 is clamped with an L-shaped connecting block 91, and the L-shaped connecting block 91 can drive the pressing head 94. The device moves left and right on the connecting rod 8, so that the pressing head 94 can detect the display screen. When the placement slot 103 after detection moves to the bottom of the infrared sensing device 13, the telescopic rod 1012 drives the push rod 109 to extend and retract, and pushes the impurities on the surface of the placement plate 1010 into the dust suction hole 105, which helps the dust suction hole 105 to suck the surface dust into the dust suction surrounding main pipe 111, and then enters the electric dust suction pump 115 through the dust suction branch pipe 114 and collects in the collection box 12 for easy cleaning. While cleaning the placement slot 103 that has been inspected, the other end of the telescopic rod 1012 in the placement slot 103 that needs to be inspected pushes the baffle 1015, and the baffle 1015 assists the dust collection component 11 to block dust or glass shards from entering the internal components. The outer wall of the baffle 1015 is provided with an auxiliary inspection rod 1014, and the auxiliary inspection rod 1014 assists the top pressing head 94 to perform pressure resistance testing. When the display screen has been inspected, it is pushed onto the conveyor belt 14 by the auxiliary inspection rod 1014 for transportation.
