Abstract

The embodiment of the invention provides a method for maintaining and welding a base plate, and a laser welding device, relates to the field of manufacturing of liquid crystal panels, and aims to achieve the effects that the controllability of the destructiveness of the base plate and the repair rate of the base plate are improved. The method comprises the following steps of preheating metal in the regions of repair points on the base plate through laser irradiation; and shooting the repair points for more than two times through different combinations of energy and slits. The embodiment of the invention is used for maintaining metal wires of the base plate.

Description

technical field [0001] The invention relates to the field of liquid crystal panel manufacturing, in particular to a substrate maintenance welding method and a laser welding device. Background technique [0002] As the process of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor-Liquid Crystal Display) continues to improve, its cutting size has become larger and larger, so the maintenance of the substrate is becoming more and more important. [0003] The existing TFT-LCD maintenance welding method is: to shoot a laser from the back of the substrate to the maintenance point of the line, so that the upper and lower layers of metal are fused together. However, the laser energy is a randomly changing parameter, so the degree of damage to the substrate to be repaired is less controllable and the repair failure rate is higher. Contents of the invention [0004] Embodiments of the present invention provide a substrate maintenance welding meth...
