Automatic testing device for compressive property of liquid crystal screen

Abstract

The invention provides an automatic testing device for the compression resistance of a liquid crystal screen, and belongs to the technical field of compression resistance testing of the liquid crystal screen. The automatic testing device comprises a testing table, a sinking cavity with an opening in the top is formed in the testing table, a middle seat is arranged in the sinking cavity, and a bearing plate elastically slides on the top of the middle seat; an upper cover piece corresponding to the opening is vertically and slidably connected to the upper portion of the testing table, a testing pressing plate is arranged on the bottom face of the upper cover piece and located over the bearing plate, a cleaning part is arranged in the sinking cavity, and the testing table is further provided with a defective product collecting area and a taking and feeding mechanism. According to the automatic testing device for the compression resistance of the liquid crystal screen, the testing process, the cleaning process and the material taking, placing and conveying process are scientifically and reasonably combined together, the safety and the testing efficiency of the liquid crystal screen testing process are effectively improved, the high integration degree and the high automation degree are achieved, and the manual participation degree in the testing process is reduced.

Description

technical field [0001] The invention relates to the technical field of pressure resistance testing of liquid crystal screens, in particular to an automatic testing device for the pressure resistance performance of liquid crystal screens. Background technique [0002] The LCD screen needs to be tested for its compressive performance during the production process. The testing process mainly includes three steps: feeding, testing and reclaiming. [0003] At present, the efficiency of testing the compressive performance of the LCD screen by the test device is relatively low, especially in the aspect of dealing with the cracking of unqualified products, the corresponding measures are not perfect, and it is not scientific and reasonable with the compressive performance testing process. The combination of these tests will seriously reduce the efficiency of the test. At the same time, due to the high degree of manual participation in the processing process, there are certain safety ...

[0003] At present, the efficiency of the test device for testing the compressive performance of LCD screens is relatively low, especially in terms of dealing with the cracking of unqualified products, the corresponding measures are not perfect, and they are not scientific and reasonable with the compressive performance test process The combination of these will seriously reduce the efficiency of the test. At the same time, due to the high degree of manual participation in the processing process, there are certain safety hazards, which are likely to endanger the health of the staff.
