AI Technical Summary

Technical Problem

When printing solder tape fixing glue, the existing screen plates are prone to damage other components on the battery cell, such as solder paste, resulting in poor soldering and other defects, affecting the quality of the battery cell.

Method used

A screen plate is designed with a position avoiding groove, which extends from the first side to the second side, and has a depth greater than the height of the target object on the piece to be printed, and is used to avoid the target object and prevent the screen plate from contacting the target object directly.

Benefits of technology

Through the design of the position avoidance slot, when printing with screens, the target objects on the battery can be effectively avoided, prevented from being damaged, improve welding yield, reduce the probability of dummy welding, and ensure the quality of the battery.

Abstract

The utility model is applicable to the technical field of screen printing, and provides a screen printing plate, a screen printing machine, a battery piece and a photovoltaic module, the screen printing plate comprises a first side surface, a second side surface and a printing hole, the printing hole penetrates through the screen printing plate and is communicated with the first side surface and the second side surface, the first side surface is close to a to-be-printed piece, and the second side surface is far away from the to-be-printed piece. The screen printing plate is provided with an avoiding groove, the avoiding groove extends from the first side face to the second side face, and the avoiding groove is used for avoiding a target object on a to-be-printed piece. Through the arrangement, when the screen printing plate is used for printing, the avoiding groove can avoid a target object, so that the target object or an area corresponding to the avoiding groove is protected, and the quality of a to-be-printed piece is guaranteed.
