Description

Technical Field

[0001] The invention relates to the technical field of copper bar welding, in particular to a copper bar welding fixing tool and copper bar welding equipment. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is made of copper and is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section (rounded copper busbars are generally used to avoid tip discharge). It plays the role of transmitting current and connecting electrical equipment in the circuit.

[0003] Through searching, the Chinese patent announcement number CN118455890A relates to a copper bar welding fixture and copper bar welding equipment. The copper bar welding fixture includes a frame seat, an operating table, a forming support plate and a clamping mechanism; the operating table has a first surface for placing the copper bar; the forming support plate is embedded in the center of the operating table; the clamping mechanism is arranged on the frame seat, and the clamping mechanism includes two clamping components, and the projections of the two clamping components on the first surface are located on both sides of the forming support plate; the clamping component includes a first driving member and a pressing plate, and the clamping component is configured to switch between a clamping state and a loosening state, so that the pressing plate is driven by the first driving member to lift and lower to clamp the copper bar on the operating table or loosen the copper bar; wherein a flow channel for fluid to pass is arranged inside the pressing plate and / or inside the operating table. The copper bar welding fixture provided in the embodiment of the application can improve the conductive effect and quality of the welded busbar, reduce the labor cost of welding, and speed up the welding rate;

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] 1. When brazing the copper busbar, due to its flat shape, the fluidity of the solder is affected during the soldering process, and the solder cannot penetrate into the inside of the copper busbar where it is bonded. As a result, the soldering position of the copper busbar is not firm and a cold solder joint occurs. After power is turned on, it will not only cause oxidation corrosion at the welding position, but also affect the conductivity of the copper busbar.

[0006] 2. The copper busbar surface cannot be cleaned before welding. Since there will be oil and oxide film on the copper busbar surface, the connectivity of the weld position will be affected during welding, affecting the firmness of the weld.

[0007] 3. It is inconvenient to adjust the position of the copper busbar during welding, and the welding length cannot be determined in advance before welding. Therefore, not only the welding length cannot be determined in advance, but also the copper busbar cannot be clamped and fixed after the position is changed. Summary of the invention
