A kind of anti-collision test equipment and test method of liquid crystal display

Abstract

The invention discloses anti-collision test equipment and a test method for a liquid crystal display screen. The anti-collision test equipment comprises a working table, a connecting table, a fixed table and a test table. Through the arrangement of the fixed table, a liquid crystal display screen slides downwards along a guide slot of the fixed table when being fixed. When the two corners of the bottom end of the liquid crystal display screen slide to be clamped to a clamping plate A, a clamping plate B automatically clamps the two corners of the top end of the liquid crystal display screen. The fixing mode is simple and fast, and therefore, the test efficiency of the liquid crystal display screen is improved. A movable plate pulls a steel wire rope after bearing the gravity of the liquidcrystal display screen, the steel wire rope pulls a rotating column under stress, part of the gravity of falling of the liquid crystal display screen is converted into a pulling force, and the fallingof the movable plate is relieved. The falling speed of the liquid crystal display screen is limited, and the situation that the liquid crystal display screen is impacted by falling due to the too high falling speed is avoided. Through the arrangement of an air cushion, the testing strength can be adjusted at will according to different products.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a liquid crystal display anti-collision testing equipment and testing method. Background technique [0002] Liquid crystal display is a kind of flat-panel display. It is used for the screen display of televisions and computers. Its structure can be regarded as composed of a frame and a screen. If the liquid crystal display is in use, the screen and the frame often separate from each other after being hit. , resulting in damage to the LCD screen, so when the LCD screen officially leaves the factory, it is necessary to test the connection between the screen and the frame. [0003] When the existing liquid crystal display anti-collision test device is in use, the fixing steps of the liquid crystal display are cumbersome. For a large number of liquid crystal displays that need to be tested before leaving the factory, the efficiency of the test is very important, so a fixing s...
