Method of and apparatus for automatically presoldering the solar battery and soldering a lead wire to the solar battery

摘要

A plurality of solder bumps (36) are arranged in a row at regular pitch in a lead wire soldering region (7) of a solar battery. A soldering apparatus for soldering a lead wire (10) to the lead wire soldering region (7) via the solder bumps (36) comprises a lead wire feeding section (11) for feeding out the lead wire (10). An end of the lead wire (10) in the lead wire feeding section (11) is chucked and the lead wire is laid over all length of the row of solder bumps (36). The soldering apparatus further comprises a soldering unit (18) for soldering the lead wire (10) onto the solder bump (36). The soldering unit (18) has a lead wire holding member (50) for holding the lead wire (10) on a solder bump (36) and a soldering iron (47). The soldering apparatus repeats an operation for welding the lead wire (10) to the solder bump (36) by means of the soldering iron (47), while the lead wire (10) is held by the lead wire holding member (50).
