Problems solved by technology

[0004] In the production process of lithium batteries, spot welding needs to be used for welding. At present, sandpaper is commonly used to polish the spot welding pin, that is, the heat transfer medium. After sanding, it is easy to cause deviation of the grinding shape, which will seriously affect the welding quality and welding effect. , thus adversely affecting the overall performance of the lithium battery

Abstract

The invention relates to a spot welding needle grinding device. The spot welding needle grinding device comprises a moving mechanism, a rotating mechanism, clamping mouths, welding needle bodies, a connection rack and lower fixtures. According to the spot welding needle grinding device, the welding needle bodies are fixed to the lower portion of the rotating mechanism through the clamping mouths,after the spot welding needle grinding device is powered on, the rotating mechanism starts rotating, then by means of stretching and contracting of the output end of the moving mechanism, ascent and descent of the rotating mechanism are realized, the corresponding welding needle bodies perform ascent and descent along the clamping mouths together, because the center portions of the lower fixturesare provided with grooves, the grooves are internally provided with grinding coatings, the welding needle bodies correspond to the grooves in the center portions of the lower fixtures, when the outputend of the moving mechanism extends downward to a certain limit, the welding needle bodies start making contact with the grooves in the center portions of the lower fixtures, thus grinding of the welding needle bodies is realized, the rotating speed of the rotating mechanism can be adjusted according to requirements, therefore the spot welding needle grinding device can perform suitable grindingon the welding needle bodies according to the actual condition.

Description

technical field [0001] The invention relates to the field of equipment related to battery production, in particular to a spot welding needle grinding device. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contai...
