Liquid crystal display shell structural strength detection device

Abstract

The invention discloses a liquid crystal display shell structural strength detection device, and relates to the field of liquid crystal display detection, the liquid crystal display shell structural strength detection device comprises a supporting seat, a fixing plate is mounted at the top end of the supporting seat, a hydraulic push cylinder is mounted on the end surface of the fixing plate, a plurality of groups of extrusion sheets are mounted in the hydraulic push cylinder, and a partition plate is mounted between each group of extrusion sheets. Through the arranged extrusion rollers and hydraulic push cylinders, a shell can extrude a supporting plate to descend under the action of gravity, a buffer frame is installed on the supporting plate, the shell extrudes the buffer frame, a return rod is inserted into a sliding resistor, a circuit is switched on, and a wire can supply power to an electromagnetic spring rod; an electromagnetic spring rod pulls a movable plate to be close to a fixed plate, an extrusion roller can extrude a shell to be attached to an extrusion piece, pressure is detected through a pressure sensor, and under the action of gravity, the shell continuously pushes a supporting plate to descend, so that the shell can slide downwards on the outer side of the extrusion roller.

Description

technical field [0001] The invention relates to the field of liquid crystal screen detection, in particular to a device for detecting the structural strength of a liquid crystal screen shell. Background technique [0002] Liquid crystal display A type of display used in digital clocks and many portable computers that uses two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid causes the crystals to rearrange so that light cannot pass through them. Therefore, each crystal is like a shutter, which can both allow light to pass through and block light. During the production process of the existing LCD screens, the strength of the LCD screen needs to be tested to avoid that the strength of the LCD screen does not meet the requirements, resulting in the quality of the produced LCD screen not meeting the standard. [0003] Existing detection methods usually use a heavy hammer to directly impact the display case ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, the object of the present invention is to provide a device for detecting the structural strength of the liquid crystal screen shell, so as to solve the technical problems that the magnitude of the applied force cannot be changed according to the structure of the display screen, and the local pressure cannot be applied to the liquid crystal screen shell.
