Description

Technical Field

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

[0002] TFT displays are a type of flat-panel display, used for television and computer screens. Liquid crystal displays use a liquid crystal solution between two polarized materials. When an electric current passes through the liquid, the crystals rearrange to create an image. LCD screens require strength testing 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 during 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 due to dust or glass debris generated by unqualified equipment. The shattered display screen causes fragments to fly, which not only increases the difficulty of subsequent cleaning, but also makes the fragments easy to fly during the shattering process. If the dust and debris accumulated on the workbench are not cleaned 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

[0045] Working principle: when the device needs to be used, the control switch 4 is started, and the display screen to be tested is placed in the placement groove 103.

Since the outer wall of the flexible plate 104 connected to the placement plate 1010 is provided with a buffer component 1016, on the one hand, the shaking caused by the lowering of the display screen is slowed down, and on the other hand, the device is located at a lower position in the placement groove 103 during testing, effectively preventing the safety reduction caused by the splashing of glass fragments of unqualified display screens. When the first drive motor 102 starts running, the sliding column 74 slides on the guide rod 72. Since one end of the sliding column 74 is connected to the connecting rod 8 through the first connecting plate 76, when the connecting rod 8 moves up and down in the sliding groove 62, the sliding column 74 effectively assists the connecting rod 8 to reduce the shaking of the equipment. The inner wall of the connecting 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 connecting rod 8 moves left and right to facilitate the pressing head 94 to detect the display screen. When the placement slot 103 after the detection moves to the bottom of the infrared sensing device 13, the telescopic rod 1012 drives the push rod 109 to extend and retract, pushing the impurities on the surface of the placement plate 1010 into the dust suction hole 105, assisting 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 it 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. 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. The auxiliary inspection rod 1014 assists the top pressing head 94 to perform pressure resistance testing. When the inspection is completed, the display screen is pushed onto the conveyor belt 14 by the auxiliary inspection rod 1014 for transportation.
