Silk screen repairing device and method with defect positioning function

Abstract

The invention discloses a silk screen repairing device and method with a defect positioning function. The device comprises a workbench unit, a control unit, a positioning unit, a display unit and a defect identification unit. The workbench unit is used for placing a to-be-repaired product and limiting the to-be-repaired product; the positioning unit is used for calibrating coordinates of a to-be-repaired product plane and providing position information; the display unit is used for shooting and amplifying defects of the to-be-repaired product at the current position; the defect identification unit is used for identifying the position of a defect on the surface of the to-be-repaired product, so that the defect can be quickly found and repaired; the control unit is used for controlling the positioning unit, the display unit and the defect identification unit to move in the X direction or the Y direction. On the basis that positioning is completed, the positions of the defects are marked through the light spots emitted by the laser, an operator can conveniently and rapidly find the positions of the defects on the silk screen, the defect marking function is achieved, and the efficiency and accuracy of silk screen repairing can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of screen printing, and more particularly, relates to a screen repairing device and method with a defect positioning function. Background technique [0002] Screen printing technology has been widely used in semiconductor, ceramics, photovoltaic and other fields. Screen printing screen is a screen with patterns made of steel wire and latex. It is used as a printing base in screen printing technology, which determines the quality of printed products to a large extent. an important component. [0003] In the photovoltaic solar cell manufacturing process, the integrity of the screen printing screen affects the quality of the subsequent printed electrodes. Therefore, the defect detection and repair of the screen printing screen is a very important step in the photovoltaic screen printing process. [0004] In most of the existing wire mesh repair processes, most manufacturers use the outdated process of manual ...
