Description

Technical Field

[0001] The utility model relates to the technical field related to battery production, in particular to a lead-acid battery welding auxiliary device. Background Art

[0002] Lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is in the discharged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the charged state, the main components of the positive and negative electrodes are both lead sulfate. During normal operation of the lead-acid battery, the electrolyte will not leak from the battery terminals or casing, and there is no free acid. Lead-acid batteries are easy to maintain, have a long service life, stable quality, and high reliability. They are widely used in various industries.

[0003] When making lead-acid batteries, pole groups (ear groups) are usually welded manually by workers. When manually welding the pole groups of lead-acid batteries, the lead-acid batteries need to be combined together and then welded to the positive and negative electrodes of the batteries by welding the battery connectors. After welding, the individual lead-acid batteries are not convenient to move. The lead-acid batteries need to be straightened before welding. During manual welding, the position of the lead-acid batteries is not accurate enough, and certain auxiliary equipment is required to ensure the accurate position of the lead-acid batteries. During welding, the welding rod molten liquid is easily splashed at the welding point, which may cause serious damage to the battery. Utility Model Content

[0006] Further preferably, the fixing structure includes a screw rod arranged in the middle of the end cover and a connection hole arranged on the side wall of the welding box, the front end of the screw rod is a smooth section inserted into the connection hole and connected to the bearing arranged in the connection hole, the end cover is provided with a rotating member connected to the screw rod through the bearing, and a handle is provided at one end of the screw rod away from the welding box. The screw rod is driven to rotate by rotating the handle, thereby adjusting the distance between the end cover and the welding box, and after the end cover is tightly attached to the welding box, the clamping strip above the end cover is pressed against the top of the cover plate to fix the cover plate.

[0007] More preferably, vertical partitions are arranged in the placement groove from left to right, and the two ends of the vertical partitions are respectively inserted into the corresponding partitions arranged on the front and rear side walls of the welding box. The battery pole groups are separated by the partitions, which is convenient for fixing the battery pole groups in the partitions and subsequent subpackaging.

[0008] More preferably, the front and rear sides of the welding box are respectively provided with placement grooves for placing the cover plate and the mounting partition plate.
