Welding frame for lead-acid storage battery

Abstract

The invention discloses a welding frame for a lead-acid storage battery. The welding frame comprises a working table and a mould box arranged on the working table, wherein the mould box comprises a positioning frame, a bracket, a pressing device and at least one positioning box; the positioning frame is provided with a connection shaft, is rotationally arranged on the bracket through the connection shaft, and is used for clamping the positioning box; the positioning box comprises a fixed plate and a movable plate; the positioning frame is provided with a guide groove; and the pressing device can drive a pressure plate to move along the guide groove for pressing a pole piece and a spacing plate which are clamped between the fixed plate and the movable plate. As the positioning box comprises the movable plate capable of moving, a pole lug is first arranged downward, the spacing plate is not beyond the connection place of the pole piece and the pole lug, the pressing mechanism can press or release the pole piece and the spacing plate which are clamped in the positioning box, the positioning frame rotates to drive the rotation of the positioning box to allow the pole lug is to be upward for welding, so that the burn injury or the scald injury of the spacing plate can be prevented, the positive-negative cross infection of pole sets can be avoided, the production efficiency is improved, and the production intensity is reduced.

Description

technical field [0001] The present application relates to the field of lead-acid batteries, in particular to a welding frame for lead-acid batteries. Background technique [0002] At present, when many manufacturers produce batteries with non-folding sheet separators, the process flow is welding first and then inserting the separators. Since the separators are PVC boards, it is easy to burn or scald the separators after wrapping the plates first and then welding. However, the separator is inserted after welding, and the positive and negative plates are not separated by the separator during welding, resulting in cross-contamination of the positive and negative pole groups, which affects the performance of the product. At the same time, due to the difficulty of inserting the separator into the welded pole group, not only the defective product rate of the product is increased, but also the labor intensity is increased, which seriously affects the production efficiency.

Problems solved by technology

[0002] At present, when many manufacturers produce batteries with non-folding sheet separators, the process is welding first and then inserting the separators. Since the separators are PVC boards, it is easy to burn or scald the separators after wrapping them first and then welding them.

However, the separator is inserted after welding, and the positive and negative plates are not separated by the separator during welding, resulting in cross-contamination of the positive and negative pole groups, which affects the performance of the product.

At the same time, due to the difficulty of inserting the separator in the welded pole group, it not only increases the defective product rate of the product, but also increases the labor intensity, which seriously affects the production efficiency
