Device for detecting flatness of liquid crystal display screen frame

Abstract

The invention discloses a device for detecting the flatness of a liquid crystal display screen frame. The device comprises an operation platform, an electromagnetic slide rail, a fixed baffle, a motor, a screw rod, a slide rod, a controller and a fixed base and is characterized in that fixed rods are vertically mounted at the four corners of the top end of the fixed base, the operation platform istransversely mounted at the top ends of the fixed rods, the controller is mounted in the middle of one side of the operation platform, and the fixed baffle is vertically mounted on one side of the top end of the operation platform. The device has the advantages that the device is provided with the motor, the screw rod, a second bearing block, a threaded slide sleeve, a threaded slide sleeve shelland an infrared range finder, the motor drives the screw rod to rotate when the device is used, the threaded slide sleeve rotates to drive the threaded slide sleeve shell and the infrared range finder to move so as to measure the distance between the liquid crystal display screen frame and the infrared range finder to check whether the liquid crystal display screen frame is flat or not, and the device is simple in structure and convenient and efficient to operate.

Description

Technical field [0001] The invention relates to the technical field of liquid crystal display screen detection devices, in particular to a liquid crystal display screen frame flatness detection device. Background technique [0002] Liquid crystal display is a kind of flat panel display, used for the screen display of TV and computer. The advantages of this display are low power consumption, small size and low radiation. The liquid crystal display uses two pieces of polarized materials. Liquid crystal solution, when the current flows through the liquid, the crystal will be rearranged to achieve the purpose of imaging. Therefore, the detection of the frame balance of the LCD screen is an important part of the quality inspection of the LCD screen, but the existing LCD screen detection device is not only The detection is not accurate and the efficiency is low. Summary of the invention [0003] The purpose of the present invention is to provide a device for detecting the flatness of t...
