Description

Lead-acid battery plate ear cleaning device

This invention relates to a device related to battery manufacturing technology, specifically a laser cleaning device that can remove oxides on the surface of the ear base in a non-contact manner.

Lead-acid batteries are commonly used in vehicles and uninterruptible power systems (UPS). With the advancement of technology, the size of lead-acid batteries is getting smaller and smaller, and their precision is also improving. Generally, lead-acid batteries have a plurality of storage tanks isolated in a shell. Each storage tank stores a battery pole group and an acid solution. The acid solution can chemically react with the battery pole groups to achieve electrical energy conversion. Effect.

The above-mentioned battery pole group is composed of a plurality of staggered and spaced plates that are stacked and arranged in an array. Each plate is provided with a protruding lug. The ears on the plates are respectively provided with power supply terminals according to the positive and negative poles of the output current. The bridges of each electrode plate are connected in series to form positive and negative electrodes through the bridge connection of the bridges.

It is known that the electrode plate is made of lead material, and there are oxides on the surface of the tip. If the surface oxide is not removed cleanly, it will not only affect the conductive efficiency, but also cause the battery to generate waste heat during operation; in order to ensure that the bridge can Stably combined with the ear base, during the battery manufacturing process, the ear base needs to be cleaned to achieve good conductive efficiency.

The traditional method of cleaning the ear base is usually to set up an ear base cleaning unit/processing station during the transfer and transportation of the electrode plates. The ear base cleaning unit has a high-speed rotating copper brush. When the electrode plate passes through the ear base cleaning unit, the ear base cleaning unit passes through the ear base cleaning unit. The high-speed rotating copper brush grinds the lug base of the electrode plate to remove the oxide on the surface of the lug base.

This method of using a copper brush to brush the ear base cannot precisely control the thickness and uniformity of the brushing, so oxides often remain in the ear base. Secondly, the metal shavings generated by brushing the ear base are not easy to clean, and the metal shavings remaining on the ear base will also affect the ear base. Subsequent bridge welding process and conductive efficiency.

The author once developed an ear root cleaning method that adheres a reducing agent to the surface of the ear root. Although it has a very good effect, the residue of the reducing agent also needs to be further removed to avoid affecting the stability and conductive effect of subsequent bridge welding. Coupled with issues such as reducing agent dosage, cost, and environmental pollution, it is still worth thinking about whether there is a more ideal cleaning method.

In view of this, the author has accumulated many years of research and practical experience in related fields, and specially created a lead-acid battery plate ear root cleaning device, which improves the known technology of using contact method to brush the ear root surface, which easily leaves oxides and produces powder. The problem of crumbs.

With the above structure, the electrode plate lug cleaning device uses laser light to irradiate and heat the electrode plate lug surface to melt the electrode plate lug surface and thereby remove oxides. It does not use contact brushing to remove surface lug oxides like the known technology, resulting in There are problems with oxide residue and dust generation.
