Device for picking and placing liquid crystal display screen

Abstract

The invention relates to a device for picking and placing a liquid crystal display screen. The device comprises a first guide rail fixed on a stander of liquid crystal display screen process equipment, a feed dispenser which is movably arranged on the first guide rail, and a drive mechanism for driving the feed dispenser to move; the feed dispenser comprises a connecting piece connected with the drive mechanism and a chassis for gripping a liquid crystal display screen; and the chassis is rotationally connected with the connecting piece by taking a straight line parallel to the level as an axis. The device for picking and placing the liquid crystal display screen can be used for transmitting the liquid crystal display screen between a front process and a picture check station, can tilt the chassis in the process of transmitting the liquid crystal display screen, and can obliquely arrange the liquid crystal display screen on a carrying station of a production line, thereby avoiding the poor phenomena caused by touching the liquid crystal display screen by hands of an operator, shortening the operation time and further improving the production capacity.

Description

technical field [0001] The invention belongs to the field of liquid crystal display process equipment, in particular to a liquid crystal display pick-and-place device with a tiltable chassis. Background technique [0002] The manufacturing process of thin film transistor liquid crystal display (TFT-LCD) is roughly divided into three stages, namely array manufacturing process, liquid crystal panel manufacturing process and module assembly. In the process of module assembly, it is necessary to combine and install the backlight unit and the circuit unit composed of the driver IC and the circuit board on the liquid crystal panel to form a liquid crystal display module. [0003] Generally, after the assembly of the circuit unit and the LCD panel is completed, it is necessary to perform a lighting inspection on the LCD screen, that is, to place the LCD screen on the front side of the backlight unit, light the backlight unit, and input a specific signal to the circuit unit of the L...

AI Technical Summary

Problems solved by technology

[0004] At present, the detection process is completely completed by manual operation. Since the LCD screens produced in the previous process are all placed horizontally on the assembly line, the viewing angle of the operator is not good, so the LCD screen must be tilted at a certain angle before proceeding. Screen inspection, due to the manual handling of the LCD screen, the sweat or moisture on the gloves can easily corrode the conductive terminals of the LCD screen, and the static electricity generated by friction during the pick-and-place process may also damage the LCD screen and cause defects; In addition, since the tilting process of the LCD screen takes up working time, it will reduce production efficiency and affect the capacity of the assembly line
