Metal material cutting and trimming device for lithium battery and manufacturing process of metal material cutting and trimming device

Abstract

The invention discloses a lithium battery metal material cutting and trimming device and a manufacturing process thereof.The lithium battery metal material cutting and trimming device comprises a processing box body, an upper cavity and a lower cavity are formed in the processing box body, and detachable universal wheels are arranged at the bottom of the processing box body; the upper cavity is provided with a material pushing device, a cutting device, a material pressing device, a first motor box and a cleaning device, a first partition plate is arranged between the upper cavity and the lower cavity, a square through hole is formed in the first partition plate and located under the material pressing device, the first motor box is arranged at the end of the square through hole, and a second partition plate is arranged at the end of the second motor box. And the lower cavity is provided with a movable trimming device, a blower device and a surface grinding device. The battery metal sheet cutting and trimming device has the beneficial effects that the pushing device and the cutting device are matched with each other, so that cutting can be carried out at the same time, the cut metal sheet is placed on the supporting panel, the battery metal sheet can be continuously cut and trimmed, and the cutting and trimming speed is increased.

Description

technical field [0001] The invention relates to the technical field of lithium battery metal material manufacturing, in particular to a metal material cutting and trimming device for lithium batteries and a manufacturing process thereof. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and uses 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. With the development of science and technology, lithium batteries have become the mainstream; lithium metal batteries generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative ...

AI Technical Summary

Problems solved by technology

[0003] However, although the existing production methods can produce lithium battery metal sheets, there are still many defects: 1. Before the lithium battery metal material processing process, the battery metal material sheet is first placed on a punching machine for cutting, so that it can be cut To meet the needs of different sizes of lithium battery materials, the battery metal sheets are further placed in different molds for processing, and the battery metal sheets are cut and processed. Although the molds in this type of processing can guarantee one-time processing of multiple pieces, but For the cutting in the early stage and putting it into the mold for processing in the later stage, the battery metal sheet is repeatedly placed and adjusted, which seriously affects the production efficiency

2. In the process of cutting the existing battery sheet metal, due to the high noise of the punching machine, and in the process of stamping, it is easy to break the discarded battery sheet metal material, and when the sharp gold plastic sheet pops up, it is easy to cause cause serious harm to the human body

3. After the existing battery metal sheet is cut, the battery metal sheet needs to be placed on the grid plate for washing, so that the waste residue on the surface can be quickly removed, but first the battery metal sheet after trimming is cut After the cutting is completed, wash it directly with water, it is easy to absorb the waste residue after cutting on the top of the battery metal sheet, and it is not conducive to the subsequent air-drying device to remove the waste residue on the surface

4. After the existing battery metal sheet is cut during the processing process, because the trimming progress is relatively high, the traditional trimming device rotates faster, which may easily cause the thin battery metal sheet to be excessively edged during trimming. Trimming, and difficult to control, resulting in high scrap rate of battery metal sheets
