Description
Technical Field
[0001] The utility model relates to the technical field of horizontal battery production automation equipment, in particular to a horizontal battery tab processing device. Background Art
[0002] In the production process of horizontal batteries, one of the steps is to perform casting welding operations on the tabs of horizontal batteries. The casting welding operation of the tabs is to cast weld the relevant parts of the tabs through lead liquid to make them into one body. Before the casting welding operation, the surface of the tabs must be treated clean and smooth. At the same time, before feeding the tabs into the lead liquid for casting welding, it is necessary to dip the tabs in casting flux and tin. However, if the casting flux is not dried, it is very easy to cause lead explosion and tin explosion accidents during the subsequent tin dipping operation and casting welding operation, which is likely to cause harm to the operators. At the same time, the welding effect of the battery is not ideal; meanwhile, at present, the pretreatment of tab casting welding still relies on manual processing to a large extent, and an automated and intelligent operation system has not been formed, and it is difficult to improve the processing efficiency.

[0038] 6. The moving flat plate seat carries the mechanism above to complete the casting flux dipping process again. The hot air blowing mechanism dries the casting flux on the surface of the tab. After the treatment is completed, the moving flat plate seat returns to the origin.
[0039] 7. The casting fixture lifting mechanism descends and is transported by the main machine to other casting welding processes for the next operation.
