Description

Technical Field

[0001] The utility model relates to the technical field of burn-proof mechanisms, in particular to a burn-proof mechanism for terminal welding. Background Art

[0002] Terminal welding is a process used in lead-acid battery technology, primarily in lead-acid battery production. The process involves assembling the positive and negative plates and separators according to design requirements, placing them into a cast welding mold, and then cast welding them to form the positive and negative electrode groups. During assembly, after the battery cover and battery compartment are sealed, the terminal posts on the terminal group in the battery compartment automatically enter the inner cavity of the lead pipe on the battery cover. Next, a welding mold is placed over the lead pipe, and the lead pipe and the upper portion of the terminal posts are flame-melted. After cooling and solidification, the terminals are formed.

[0003] Currently, during the battery production and assembly process, the flame during terminal welding can burn the battery casing, affecting the battery's appearance. In severe cases, it can cause the battery to fail the airtightness test, and the damaged battery cannot be sold. Therefore, we have proposed a burn-proof mechanism for terminal welding to solve the above problem. Utility Model Content

[0015] Beneficial effects of the utility model:

[0016] 1. Through the threaded sleeve, the threaded sleeve can compress the compression spring through the limit plate. The compression spring can exert downward squeezing force on the anti-burning plate. When the battery is placed under the anti-burning plate, the compression spring can press the anti-burning plate tightly against the top of the battery, so that the battery terminal passes through the terminal hole. This prevents the flame from burning the battery shell during the terminal welding process, affecting the battery appearance, and in severe cases causing the airtightness test to fail, and the damaged battery cannot be sold;

[0017] 2. The adjustment seat can be fixed and released by the action of the knob, threaded clamp, threaded hole and slot. By moving the adjustment seat, the adjustment seat can drive the anti-burning plate to adjust the height through the support plate, thereby achieving the purpose of preventing burning when welding terminals of batteries at different heights.
