Description

Technical Field

[0001] This utility model relates to the field of automated auxiliary production of space solar cell arrays, specifically a pre-laying tooling for cable networks of space solar cell arrays. Background Technology

[0002] Currently, my country commonly uses aluminum honeycomb structures made of carbon fiber and polyimide film as rigid substrates for space solar cells, known as rigid solar arrays. These arrays serve as the most important energy source and core component of the energy system for satellites and other spacecraft operating in orbit. With the rapid development and market competition in the commercial aerospace sector, rigid solar arrays are widely used due to their high rigidity, low production cost, and lightweight characteristics.

[0003] Traditional manufacturing processes require bonding spatial solar cells to the front of a rigid substrate, while fixing posts are bonded to the rigid back according to the cell array circuit design and size requirements. Then, multiple cables are positioned, laid, and installed on the front of the substrate according to the power requirements of each array by laying a cable network.

[0004] The traditional cable network laying process for solar cell arrays has the following shortcomings or areas for improvement: 1) Due to the large size of the substrate and the variations in cable lines depending on the product specifications, there are many steps involved in laying cables on the back of the substrate, especially in positioning the cables to the substrate, resulting in high labor intensity; 2) Since the cable laying process is mainly manual, there is a lack of consistency between the production process and the appearance of the laid cable when producing large quantities of products; 3) The existing cable laying process is time-consuming, and its compatibility with other processes needs to be improved in order to reduce the overall development time of the solar cell array product and improve production efficiency.

The cable positioning elastomer has an elastomer binding and threading hole inside that corresponds to the position of the binding and threading hole of the profile. The tool handle is fixed at different positions on the front of the combined profile to facilitate manual gripping. The tooling positioning device includes a positioning slider, a telescopic rod, and a positioning seat. One end of the telescopic rod is fixed to the composite profile, and the other end is fixed to the positioning seat. The telescopic rod is extended and retracted by sliding the positioning slider to adjust the relative position between the positioning seat and the composite profile. The cable binding wire, through the wire-passing hole of the profile and the wire-passing hole of the elastic body, is used to bind and fix the cable to the composite profile; The substrate is provided with connection holes for mechanical positioning of the battery circuit section and the satellite body. The size of the connection holes is similar to that of the positioning seat. The positioning seat is inserted into the connection holes on the substrate to fix the relative positional relationship between the cable and the substrate.

[0007] Furthermore, the cable is composed of one or more strands twisted together at different locations.

[0008] Furthermore, the cable positioning elastomer is a thermoplastic elastomer formed by injection molding or 3D printing.

[0009] Furthermore, the tool handle is fixed at different positions on the front of the composite profile by screws.
