A wire drawing and cutting device

Abstract

The invention discloses a wire drawing and cutting device for straightening and cutting a solder strip. The wire drawing and cutting device comprises a horizontal moving device, a wire drawing device, a wire cutting device, a wire moving track and a control system, wherein the wire drawing device is arranged on the horizontal moving device; clamping claws are arranged on the wire drawing device and used for clamping the solder strip and drawing the solder strip to a specified worksite; the wire cutting device is arranged on the horizontal moving device; a cutter is arranged on the wire cutting device and used for cutting off the solder strip which is drawn out by the wire drawing device; the wire moving track is arranged inside the wire cutting device and used for providing a running passage for the solder strip; the control system is electrically connected with the wire drawing device and the wire cutting device and used for controlling the wire drawing device and the wire cutting device to move forwards and backwards on the horizontal moving device. By adopting the wire drawing and cutting device disclosed by the invention, the solder strip can be automatically straightened and cut off during a welding process of the solder strip and a battery piece, so that the welding quality and the welding frequency are improved, and relatively high automation degree is realized.

Description

technical field [0001] The invention relates to a wire-drawing and cutting device, in particular to a wire-drawing and cutting device for straightening and cutting off welding strips in the process of string-welding photovoltaic module cells. Background technique [0002] With the development of science and technology, the industry is developing rapidly. At the same time, the pollution of the environment is becoming more and more serious. For the sake of human health, human beings are promoting the concept of green environmental protection all the time, so the concept of green environmental protection has gradually become popular among the people. As a kind of green energy, solar energy can save energy and has low cost. It just adapts to the trend of green environmental protection and is more and more popular and applied. Following this trend, the solar photovoltaic panel industry is booming. [0003] Solar photovoltaic panel assembly is a power generation device that collec...

AI Technical Summary

Problems solved by technology

In the production of solar photovoltaic modules, multiple cells need to be connected together in series. When welding in series, the ribbon needs to be straightened and cut off after welding. However, these two tasks are currently performed manually, which will cause tension. Unbalanced or biased welding strips cause stress changes in the welding strips, which reduces the effect of stringing the cells and fails to meet the welding requirements; at the same time, manual operation is time-consuming and laborious, and the welding efficiency is low, which cannot meet the needs of automated production.
