With the advent of the era of science and technology, the development of the new energy industry is in a stage of vigorous rise. The improvement of people's requirements for quality of life has also promoted the new energy industry is currently in a stage of rapid development, in human travel such as cars, in home appliances such as vacuum cleaners, in portable items such as charging treasures, including other products that need to be charged in our daily lives and can be recycled. In the past, we had to rely on 220V power supply to use products, but this way would bring a lot of inconvenience to our lives, so with the development of the times, this way was gradually replaced by rechargeable products with tailless electrical appliances. Rechargeable products and other products need to be equipped with lithium battery packs to store electricity.
There are also many types of lithium battery packs, such as aluminum shell batteries, pouch polymer batteries, and cylindrical batteries. These three categories are the most common types of battery packs on the market, and today we mainly understand the composition of cylindrical batteries.
Lithium battery packs are multiple cells welded together by series and parallel. Battery cells, battery protection boards, battery connectors, cell holders, etc. are processed into products required by customers through the combination of battery PACK process.
How to connect multiple cells into a battery pack?
The connection of the battery cell into a group requires the use of nickel sheets, and the connection between the nickel sheet and the battery cell is mainly achieved by welding, thus forming a simpler battery pack. The welding method of the battery cell and the nickel sheet is different from the welding method of other metals, and the welding of the battery cell and the nickel sheet belongs to single-sided double-point parallel welding. Lithium battery spot welding machine is a kind of welding equipment specially developed for the assembly of battery packs.
There are also many types of lithium battery spot welding machines, as a factory-scale production mainly uses the fully automatic lithium battery spot welding machine we talk about today.
Automatic lithium battery spot welding machine, no need for manual manual welding, the machine automatically completes the welding action. It greatly saves labor costs and improves production efficiency.
Automatic lithium battery spot welding machines are mainly divided into two categories: double-sided automatic spot welding machines and single-sided automatic spot welding machines.
Double-sided automatic spot welding machine: positive and negative electrodes are welded at the same time, and the welding machine has two welding heads. The sonotrode can be rotated freely at 135°, has the role of an anti-stick needle, and is also suitable for the welding of special-shaped nickel sheets. It adopts a through-type design structure (which can be forward-out or forward-out-out), which can be used with the production line through-type. It can weld 3600 cells per hour.
Single-sided automatic spot welding machine: there is only one welding head, first weld the A side, and then manually take it out and flip, and place it on the welding platform for B-side welding. It can weld 2000 cells per hour. The single-sided machine can also weld the protection plate when replacing the welding module, and the machine is dual-use.
