Angle-controllable liquid crystal display screen grinding system

Abstract

The invention discloses an angle-controllable liquid crystal display screen grinding system comprising a grinding mechanism, a bearing mechanism and an unloading mechanism. The grinding mechanism comprises a grinding fixing piece, a drive connection device and grinding wheel devices. The drive connection device is connected with the grinding wheel devices. The bearing mechanism comprises a bearingfixing piece, a main bearing table, a bearing band track and side bearing tables. The bearing fixing piece is arranged on a bearing slide rail. The unloading mechanism comprises an unloading fixing piece, an unloading slide rail and an unloading connection piece. The grinding system is further connected with a control system through wires. The control system controls the whole grinding system ina cooperation manner. Angle conversion can be conducted on a liquid crystal screen through the main bearing table, the grinding angle can be adjusted, and requirements of clients can be met accordingly. By arranging upper grinding wheels and lower grinding wheels, the upper face and the lower face of the edge of the liquid crystal screen are synchronously ground, the problem that only one face canbe ground one time is solved, the cost budgeting is reduced, finally unloading is conducted through the unloading mechanism and automated production is achieved.

Description

technical field [0001] The invention relates to the field of manufacturing equipment of liquid crystal display devices, in particular to an angle-controllable liquid crystal screen grinding system. Background technique [0002] Liquid crystal display is an active-matrix liquid crystal display driven by thin-film transistors (TFT). It mainly stimulates liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. IPS, TFT, and SLCD are all subcategories of LCD. The working principle of the liquid crystal display is: under the action of the electric field, the alignment direction of the liquid crystal molecules is changed to change (modulate) the light transmittance of the external light source, complete the electro-optical conversion, and then use the R, G, B three primary color signals With different excitations, through the red, green, and blue three primary color filter films, the color reproduction in the time do...

AI Technical Summary

Problems solved by technology

However, the device can only be fixed and does not have flexibility. In the process of manufacturing, it has high limitations.

[0004] The production process of LCD screen is very cumbersome. In the current production process, the grinding process for the terminals of the LCD screen is not mature enough. The shape of the grinding is too single. model needs

And during the grinding process, the grinding angle cannot be adjusted, and the precision is not high enough. Generally, the equipment of this process can only grind one side at a time, and then grind the other side, which increases the cost budget
