Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the present invention provides a liquid crystal panel tester with wide applicability, including: the device comprises a test board 1, a guide rod 2 arranged on the test board 1, a cylinder mounting plate 3 arranged at the top end of the guide rod 2, a lifting cylinder 4 arranged on the cylinder mounting plate 3, a sliding plate 5 sleeved on the guide rod 2 and connected with the lifting cylinder 4, a pressing plate 6 arranged on the bottom surface of the sliding plate 5, a linear guide rail 7 arranged on the test board 1, a bearing platform 8 arranged on the linear guide rail 7 in a sliding manner, a pushing device 9 arranged on the test board 1 and connected with the bearing platform 8, and a controller. The lifting cylinder 4 and the pushing device 9 are respectively connected with the controller, the lifting cylinder 4 drives the sliding plate 5 to move up and down, and the pushing device 9 pushes the bearing table 8 to move back and forth.
In this embodiment, the pushing device 9 includes a motor, a screw rod connected to the motor, and a slider disposed on the screw rod, the slider is connected to the plummer 8, and the motor drives the screw rod to rotate, so as to drive the slider to move, and further drive the plummer 8 to move back and forth.
Be equipped with a plurality of absorption holes 81 on the plummer 8, plummer 8 is inside to be equipped with the vacuum pump, the vacuum pump with absorption holes 81 pass through the pipe intercommunication. The liquid crystal panel to be tested is placed on the bearing table 8, and the vacuum pump is started to firmly adsorb the liquid crystal panel on the bearing table 8. The adsorption holes 81 are circular and are uniformly distributed on the bearing table 8, so that all areas of the liquid crystal panel are adsorbed.
