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 stringing machine, in particular to a soldering mechanism of the solar cell stringing machine. By impregnating the soldering tape with flux, the oxide and reduction of the soldering tape before welding are eliminated and reduced. The mechanism of welding surface tension plays an auxiliary welding role in the welding process. Background technique [0002] Solar cell stringing machine is a device that automatically connects the positive and negative poles of multiple solar cells in series under the control of PLC, including ribbon distribution mechanism, welding mechanism, solar silicon wafer feeding mechanism, and solar silicon Sheet positioning mechanism and automatic transfer welding stage. Solar cells are generally provided with multiple cell bus grid lines, and multiple parallel welding ribbons need to be serially welded to the multiple bus grid lines respectively. In the process of string welding of solar ...
