Solar component junction box suitable for automated assembly

Abstract

The invention provides a solar component junction box suitable for automated assembly. The solar component junction box suitable for automated assembly comprises four metal sheets which are arranged at intervals, diodes and output cables; three diodes are arranged between the second metal sheet and the first metal sheet, the fourth metal sheet and the third metal sheet, and the first metal sheet and the fourth metal sheet; a first lead wire and a fourth lead wire synchronously stretch downward, and are connected with the second metal sheet and the third metal sheet respectively through L-shaped metal confluence bands; a second lead wire and a third lead wire are connected with the first metal sheet and the fourth metal sheet respectively through straight metal confluence bands; and the two output cables are connected with the second metal sheet and the third metal sheet respectively. The four lead wires led out from a battery string are led out on the same bedding plane and connected with the four metal sheets in a high-low staggering way, so the process requirement of automatically assembling a battery component is met.

Description

technical field [0001] The invention relates to a solar battery module, in particular to a junction box of a solar battery module. Background technique [0002] The output voltage, current, and power of a single solar cell are very small. Generally speaking, the output voltage is only about 0.5V, and the output power is only 1-4W, which cannot meet the requirements for power supply applications. In order to increase the output power, multiple single cells need to be reasonably connected and packaged into components. When more power is required, it is necessary to connect multiple components into a square array to provide a larger current and voltage output to the load. [0003] The solar cell module junction box plays a very important role in the solar module. It is a connecting part that transmits the power generated by the solar cell to the external power line. The junction box is set on the back of the solar cell module, and is glued to the back plate of the battery mod...

AI Technical Summary

Problems solved by technology

[0005] In order to realize the automatic production of solar cell modules, the electrode connection structure in the existing junction box cannot meet the requirements of the automatic assembly process. In the automatic assembly process, it is required that the four leads A1 ~ A4 in the cell string must be located on the same layer, otherwise A complex turning mechanism must be added to the automatic assembly line, which will not only increase the complexity of the mechanical and electrical control design of the automatic assembly line, but also greatly increase the cost of the automatic assembly line, and at the same time, the reliability of the entire assembly line will also be affected. influences
