Automatic pressure connecting testing device for liquid crystal display panels

Abstract

The invention discloses an automatic pressure connecting testing device for liquid crystal display panels. The automatic pressure connecting testing device comprises a base plate, a vertical air cylinder, a horizontal air cylinder and a supporting frame for containing the liquid crystal display panels to be tested; fixed parts of the supporting frame and the vertical air cylinder ate respectively and fixedly arranged on the plate face of the base plate; a fixed part of the horizontal air cylinder is fixedly arranged on a sliding part of the vertical air cylinder through a fixed support; the horizontal air cylinder can move up and down in the vertical direction along with the sliding part of the vertical air cylinder; a pressing head is arranged at the front end of a sliding part of the horizontal air cylinder, and probes electrically connected testing ends on the liquid crystal display panels to be tested are arranged on the pressing head; backlights are arranged at the position, corresponding to the liquid crystal display panels to be tested in position in a matched mode, of the base plate. By means of the automatic pressure connecting testing device, automatic pressure connecting can be achieved, repeated mechanical labor of workers is greatly reduced, and the production efficiency is improved; when the liquid crystal display panels to be tested are taken from or placed on the supporting frame in the testing device, damage caused when the liquid crystal display panels to be tested are taken or placed can be effectively reduced.

Description

technical field [0001] The invention relates to a crimping test device, in particular to an automatic crimping test device for a liquid crystal panel. Background technique [0002] The existing liquid crystal panel inspection and crimping test device basically uses mechanical structures such as pressure elbow clamps and cam mechanisms to implement crimping testing manually, which has the following disadvantages: [0003] 1. When workers use manual crimping for detection, their arms repeat mechanical movements, which is prone to fatigue and reduces efficiency; [0004] 2. Manual crimping test device, due to its own structural limitations, when workers quickly pick and place the LCD panel under test, the LCD panel under test is likely to touch the pressure head part of the device, causing damage to the LCD panel under test (commonly known as damage) ; [0005] 3. Manual crimping test devices require manual operation, which is difficult to integrate into the automated assembl...
