Description

Technical Field

[0001] This utility model relates to the field of battery electrode technology, and more specifically, to a multifunctional electrode welding fixture. Background Technology

[0002] The electrode group welding fixture for lead-acid batteries is designed based on the number of plates, plate thickness, lug height, and electrode spacing. In normal production, each battery model has its own dedicated welding fixture. For example, Chinese patent CN202701684U discloses an electrode group welding fixture, which includes a support frame and comb-shaped templates. Two template frames are provided, sliding relative to each other along the top surface of the support frame, and the two comb-shaped templates are hinged to the corresponding template frames. While this electrode group welding fixture achieves advantages such as ease of operation and wide applicability to a certain extent, it is only suitable for electrode groups of one polarity. In basic research on lead-acid batteries, the plate thickness, lug height, and electrode spacing are basically determined, but different electrode group combinations are set according to different experimental requirements, such as three positive and two negative combinations, three negative and two positive combinations, two positive and one negative combinations, and two negative and one positive combinations, etc., resulting in numerous combination methods. If a welding fixture is manufactured for each designed electrode group combination, it is not only time-consuming and labor-intensive but also increases experimental costs. Therefore, it is necessary to design a multifunctional electrode group welding fixture that can realize electrode group welding of various plate types and combinations. Utility Model Content

The welding groove has comb teeth and electrode post grooves, and an electrode post sealing block can be placed in the electrode post grooves. The positive and negative electrode combs are fixed by an electrode comb clamp.

[0006] Furthermore, the positive electrode comb and the negative electrode comb are each provided with three welding areas; the positive electrode comb has four teeth in the welding groove; and the negative electrode comb has five teeth in the welding groove.

[0007] Furthermore, the aforementioned welding grooves are divided into region I and region II, and each region I and region II is provided with two pole post grooves at the top.
