Problems solved by technology

In the traditional welding strip processing method, each action needs to be completed before the previous action is completed, which is time-consuming and has low production efficiency, which does not meet the needs of modern high-tempo production.
Especially when dealing with dense grid welding strips, the welding strips are easy to get out of position, resulting in welding failure and affecting product quality

Abstract

The invention provides a welding strip pulling compressing device and method and a series welding machine. The welding strip pulling compressing device comprises a guiding welding strip device, a first pulling device, a second pulling device, a conveyor line and a welding strip positioning device, wherein the second pulling device is arranged at the rear side of the first pulling device; a batterypiece is put on the conveyor line; and the guiding welding strip device is arranged between the first pulling device and the second pulling device. The welding strip pulling compressing method comprises the steps that the first pulling device pulls a welding strip to the guiding welding strip device; the second pulling device pulls the welding strip to the battery piece; and the welding strip andthe battery piece are compressed together by the welding strip positioning device. The series welding machine uses the welding strip pulling compressing device and also comprises a battery piece feeding device, a welding strip feeding device and a welding device. The invention can comprehensively improve the welding operation efficiency and quality.

Description

technical field [0001] The invention relates to a device and a method for drawing and pressing a welding ribbon onto a battery sheet and a stringer using the device and method. Background technique [0002] The stringer is one of the important equipment in the production process of solar panels, which is used to weld individual cells into strings of cells. Before welding, the welding ribbon needs to be pulled out and pre-pressed and fixed on the battery sheet, so a device and method for pulling and pressing the welding ribbon is needed. [0003] The traditional welding strip processing method generally stretches the welding strip forward to a fixed length through a gripper, and then cuts it to a fixed length with a cutter. Guided by the guide plate, the gripper moves forward with the fixed-length welding strip After arriving at the position where the battery is placed, wait for the robot to release the battery. After the film is placed, the grippers release the ribbon, and ...
