Description

Technical Field

[0001] This utility model relates to the field of composite busbar hot pressing technology, specifically, to an automatic hot pressing fixture for composite busbars. Background Technology

[0002] Laminated busbars, also known as composite busbars, multilayer busbars, or composite copper busbars, are multi-layered composite structure busbars. Their production process utilizes high-efficiency hot-pressing technology and advanced insulating materials. The busbars have relatively large capacitance, increasing system capacitance; furthermore, their physical structure determines their high distributed capacitance, low system impedance, and low series inductance. The simple and compact design of laminated busbars saves internal space. In recent years, with the increasingly widespread application of laminated busbars in the new energy and automotive fields, the requirements for laminated busbars have become increasingly stringent. Electroless copper busbars not only have excellent conductivity but also reduce manufacturing costs by 10% to 20% compared to electroplated copper busbars, offering a considerable cost advantage. Therefore, they are increasingly replacing electroplated copper busbars in various applications. Electroless copper busbars are typically formed using hot-pressing molds. Hot-pressing of laminated busbars refers to the process of bonding two or more layers of copper busbars together under high temperature and high pressure using a mold to form the laminated busbar.

[0003] According to Chinese Patent CN202323607983.9, a hot pressing mold for laminated busbars is used. This application employs a movable cavity, an electric push rod, a movable plate, a pin, and a first through hole to facilitate rapid separation of the pin from the laminated busbar body, enabling easy demolding. The mold is easy to operate and improves work efficiency. The use of a slider and a sliding groove enhances the stability of the movable plate and pin's lifting mechanism, improving its structural practicality and facilitating better processing and production. However, in existing hot pressing molds for laminated busbars, the busbar temperature is high after hot pressing, posing a risk of burns to personnel handling it.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
