Welding aiding mechanism for solar cell piece series welding machine

Abstract

The invention discloses a welding aiding mechanism for a solar cell piece series welding machine. The welding aiding mechanism solves the problems of insufficient welding and infirm welding for cell pieces caused by uneven and incomplete adhesion for welding flux, existing in the prior art. A welding aiding fluid leaching submerging groove (34) and a welding aiding fluid (44) are arranged on the left half part of a welding aiding mechanism transferring platform (33), a welding strip guiding groove (36) is formed in the platform surface of the right half part of the welding aiding mechanism transferring platform (33), a welding strip downward guiding-in arc-shaped block (41) and a welding strip upward guiding-out arc-shaped block (43) are respectively arranged at the groove bottom inside the welding aiding fluid leaching submerging groove (34), a lower pressing welding strip arc-shaped block (42) is arranged on the lower bottom surface of a welding aiding fluid leaching submerging groove cover plate (35), and welding strips (13) from a welding strip delivering mechanism are further arranged between the lower pressing welding strip arc-shaped block (42) and the welding aiding fluid leaching submerging groove (34). The welding strength and reliability are improved, no pseudo welding or over welding occurs, and the welding quality and efficiency are effectively improved.

Description

technical field [0001] The present invention relates to a solar cell stringer, in particular to a soldering mechanism of the solar cell stringer, which eliminates and reduces the oxide and the The mechanism of welding surface tension plays the role of auxiliary welding in the welding process. Background technique [0002] The solar cell stringer is a device that automatically strings together the positive and negative electrodes of multiple solar cells under the control of PLC, including a ribbon distribution mechanism, a soldering mechanism, a solar silicon wafer feeding mechanism, a solar silicon Chip positioning mechanism and automatic transfer welding carrier. Generally, a plurality of cell busbars are arranged on a solar cell, and a plurality of parallel ribbons need to be serially soldered to the plurality of busbars respectively. In the process of stringing solar cells, it is very important to impregnate or spray flux on the soldering ribbon. It mainly assists heat ...
