Bar breaking device on liquid crystal display panel bar breaking equipment and bar breaking method for same

Abstract

The invention discloses a bar breaking device on a piece of liquid crystal display panel bar breaking equipment and a bar breaking method for the same. The bar breaking device comprises a working table, wherein multiple rotation shafts, a first baseplate, a material falling hole and a limiting block are disposed on the working table; a limiting sensor is disposed on the limiting block; a second baseplate is disposed under the material falling hole; a material collection box and a push plate are disposed under the working table; a bar breaking plate and a long-strip breaking cutter are disposed on the working table; and projection of the long-strip breaking cutter is located at a junction between the first baseplate and the material falling hole. The bar breaking method comprises the steps that the front end of a liquid crystal panel is pressed against the limiting block; the limiting sensor receives signals and drives a motor to stop running; a first air cylinder pushes a second baseplate to ascend; the first baseplate and the second baseplate are located on the same plane; and a laser trace on the liquid crystal display panel is located at a junction between the first baseplate and the second baseplate.

Description

technical field [0001] The invention relates to a strip-cutting device and a strip-cutting method thereof, in particular to a strip-cutting device and a strip-cutting method of a liquid crystal display panel strip-cutting device. Background technique [0002] The liquid crystal display panel is an important component of the screen of electronic products such as mobile phones and computers. The screen processing needs to cut the entire liquid crystal display panel according to the size of the screen of the electronic product. The cutting is carried out in multiple steps. The original large board is first divided into small pieces, and then the small pieces are cut into smaller shapes, and finally the required size is obtained. [0003] However, the cutting method generally is to use a laser machine to laser cut the entire liquid crystal display panel, and form laser traces with a certain depth on the entire liquid crystal display panel. In the process of laser cutting, the l...

Problems solved by technology

At present, the operation is generally carried out manually. It is necessary to place the lasered liquid crystal display panel on the workbench first. A long strip-shaped cutting knife is set on the workbench, and the human eye is used to aim at it so that the laser traces on the liquid crystal display panel are located at a long distance. Below the projection of the strip-shaped broken knife, after that, manually operate the long strip-shaped broken knife to move down to realize the strip-breaking process. Finally, the broken LCD panel needs to be slowly removed from the workbench before the next step can be carried out. Strip breaking operation, the entire manual operation process is cumbersome, prone to human eye fatigue, prone to failure of strip breaking, breaking the entire LCD panel, and low production efficiency
