Solar component lead distribution structure applicable to automatic assembly

Abstract

The invention discloses a solar component lead distribution structure applicable to automatic assembly. A first lead is led out of a battery plate string to extend downwards and extends inwards to a position corresponding to a second metal sheet in a junction box through an L-shaped metal bus bar; a fourth lead extends downwards and extends inwards to a position corresponding to a third metal sheet in the junction box through the other L-shaped metal bus bar; a second lead extends inwards to a position corresponding to a first metal sheet through a straight metal bus bar; and a third lead extends inwards to a position corresponding to a fourth metal sheet through the other straight metal bus bar. The four leads can be led out on the same layer; a lead-in structure is connected with the four metal sheets in a junction box body in a vertical staggering mode; and thus, the process requirement of automatic assembly of a cell component is met on the premise of guaranteeing electric energy output performance of the cell component.

Description

Technical field: [0001] The invention relates to a solar battery module, in particular to a lead wire distribution structure of the 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 modules. 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 pla...

Problems solved by technology

[0005] In order to realize the automatic production of solar cell components, the existing lead distribution structure of solar cell components and the electrode connection structure in the junction box cannot meet the requirements of the automatic assembly process. In the automatic assembly process, four lead wires A1 in the cell string are required ~A4 must be located on the same floor, otherwise a complex flip mechanism must be added to the automatic assembly line, which will not only increase the complexity of the mechanical and electronic control design of the automatic assembly line, but also greatly increase the cost of the automatic assembly line. The reliability of the assembly line will also be affected
