Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell sheet processing for satellites, and in particular relates to a solar cell sheet and interconnection sheet welding and forming equipment for satellites. Background Art

[0002] With the rapid development of space technology, the demand for space high-power energy systems on spacecraft is also increasing, and the application of large-area photovoltaic systems on spacecraft is also increasing.

[0003] A solar array is an array of multiple solar panels that convert solar energy into electrical energy for satellites in space orbit. The most widely used solar array form is a folding solar array with a rigid substrate, also known as a solar wing. Since it has the important task of providing energy for satellites, whether the solar wing can be smoothly unfolded and work normally after launch directly affects the success or failure of satellite launch. Satellite solar arrays are onboard power generation devices, semiconductor devices that convert solar energy into electrical energy through the photoelectric effect. The overall production process can be divided into three stages: substrate → chip, chip → battery string, battery string → solar array. The most important stage is the preparation of the chip. After the chip is prepared, it needs to be made into battery cells and then into battery strings.

[0004] Solar arrays are the main power source for spacecraft. How to effectively improve the reliability and production efficiency of solar arrays and reduce production costs has become a major issue in satellite battery components.

In the process of using independent interconnection sheet processing equipment for processing, it is easy to lead to an increase in manual welding processes and a decrease in production efficiency. In addition, the stability, reliability and efficiency of manual welding are lower than those of the equipment, and there are many uncontrollable human factors. Utility Model Content
