Description

Technical field [0001] The invention relates to the technical field of manufacturing of new energy vehicles, in particular to a high-precision welding equipment for power battery parts of new energy vehicles. Background technique [0002] With the rapid development of new energy vehicles, the power supply of new energy vehicles has also developed rapidly. Among them, the most widely used power supply for new energy vehicles is the vehicle-mounted power battery of new energy vehicles, but there are many batteries in production. The problem caused by the uneven quality of the battery products in the market, the later cycle life of the battery capacity cannot reach the designed service life, which has a great relationship with the unique production process of the battery in the production. The structure of the battery is composed of a shell, an upper cover, a pole plate, a separator, a bus bar, a pole, a bridge protection plate, and a terminal. The battery needs to be welded in clu...

Problems solved by technology

The battery needs to be welded in clusters during the production process. The existing battery production is mostly in the mechanized mode of the assembly line. However, due to special circumstances, it is usually necessary to manually weld the battery clusters. Manually connect the positive and negative battery plates in the cluster box together. Put the bars between the positive and negative tabs, the bridge posts, and the poles through the existing equipment, and then fix and weld the parts that make up the battery through oxygen welding. However, manual tools are required in the process of manual welding of new energy battery clusters. To fix the cluster box, it is necessary to manually use lead soldering tools to connect the positive and negative electrodes of the inner plate of the cluster box. Manually fixing the cluster box with tools is complicated and has poor stability. For cluster boxes of different specifications, manual adjustment of the fixing tools is required, so that Ensuring the stability of cluster welding

[0003] With the development of science and technology, welding machines are becoming more and more automatic. However, due to the various shapes of products, the positions to be welded are also different. In order to facilitate welding, the welding head must be installed at an angle and sometimes the installation angle must follow Change, in the past, when installing the welding head, many holes were processed on the mounting plate, and the welding head was fixed in the corresponding screw hole according to the slope, so that the angle adjustable range is small, the accuracy is low, and the installation and replacement time is fixed by screws Long, affect the use efficiency, affect production efficiency, and the existing welding head only has a temperature monitoring inside, no other temperature monitoring, when the welding head fails, it can not be alarmed in time, resulting in damage to the product or poor welding due to high temperature appears, affecting the welding effect
