Battery string EL repair machine

Abstract

The invention discloses a battery string EL repair machine which comprises a machine frame, an NG string feeding and positioning mechanism, a Y-axis and Z-axis transferring mechanism, an EL detection mechanism, an interchange type double repair table mechanism, a battery string conveying mechanism, a foot-pad pedal and an EL displayer, and the Y-axis and Z-axis transferring mechanism is installed on the portion, above the NG string feeding and positioning mechanism, of the machine frame. The Y-axis and Z-axis transfer mechanism transfers the NG string to an EL detection mechanism arranged on the workbench for testing, the workbench on the front side of the EL detection mechanism is provided with an interchangeable double-repair-table mechanism for receiving NG products, and the workbench on the rear side of the EL detection mechanism is provided with a battery string conveying mechanism for receiving OK products. By means of the mode, NG battery strings are repaired, distinguished feeding can be conducted according to A / B strings, leads can be accurately pressed for detection, the repairing table has the preheating function, the upper repairing table and the lower repairing table are switched, and the repairing rhythm is guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar component manufacturing, in particular to a battery string EL rework machine. Background technique [0002] When producing solar cell modules, it is necessary to weld multiple cells and ribbons into battery strings. During the production of battery strings, a string of battery strings may appear due to handling, movement, and hidden cracks in the cells themselves. A certain cell in the cell is damaged; or in the process of welding the cells into strings, the welding strip and the cell are not welded firmly, and there is a situation of virtual welding. In addition, there may be problems such as dirt and missing corners. When a certain cell in the battery string is damaged, it is necessary to replace the damaged cell in the battery string with a qualified cell. Re-weld the part where there is a weak weld. [0003] The traditional repair method is to use manual processing: when replacing the battery,...

[0002] When producing solar cell modules, it is necessary to weld multiple cells and ribbons into battery strings. During the production of battery strings, a string of battery strings may appear due to handling, movement, and hidden cracks in the cells themselves. A certain cell in the cell is damaged; or in the process of welding the cells into strings, the welding strip and the cell are not welded firmly, and there is a situation of virtual welding. In addition, there may be problems such as dirt and missing corners. When a certain cell in the battery string is damaged, it is necessary to replace the damaged cell in the battery string with a qualified cell. Re-weld the part where there is a weak weld

[0003] The traditional repair method is to use manual processing: when replacing the battery, use the soldering iron tip to remove the damaged battery from the ribbon, then replace the qualified battery to the position of the damaged battery, and then use the soldering iron to replace the damaged battery. The welding ribbon is welded to the qualified cell. This manual repair method is not only inefficient, but also because the battery string is relatively long, it is inconvenient to move the battery string during manual repair, and it is easy to cause secondary damage to the cells on the battery string. After the repair, it needs to be inspected, inspect the repaired product, and judge whether to continue the repair or whether the repair is successful according to the test result. The operation is cumbersome and the steps involved are complicated.
