Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production equipment, and in particular to production equipment for steel shell button battery covers. Background Art

[0002] Currently, the steel-cased button battery market is primarily divided into three types: cylindrical steel-cased, button-shaped steel-cased, and round soft-pack batteries. Due to their smaller size, round steel-cased button batteries are widely used in various microelectronic products. Their diameters range from 4.8mm to 30mm, and their thicknesses range from 1.0mm to 7.7mm. The exterior is made of stainless steel, serving as the positive electrode. The negative electrode is a round stainless steel cap. A sealing ring, made of nylon, insulates the positive and negative electrodes. In addition to providing insulation, the sealing ring also prevents electrolyte leakage. Steel-cased button batteries primarily consist of a positive electrode shell, a negative electrode shell, (positive / negative) electrode sheets, a diaphragm, a gasket, a spring, an upper cover, and an electrolyte. A well-developed upper cover can improve battery performance parameters such as sealing and energy density. Currently, a more advanced upper cover on the market consists of a small steel sheet, a plastic sheet, and a large steel sheet. The large steel sheet is welded to the bottom surface of the plastic sheet, and the small steel sheet is welded to the surface of the plastic sheet. The three are stacked and fixed together from top to bottom to form a concentric structure. Because this cover is a new design, there is currently no dedicated equipment for its production on the market. Therefore, its production mainly relies on manual labor. This is not only inefficient and labor-intensive, but also unable to meet the needs of large-scale mass production. It also suffers from poor quality and low yield rate. Summary of the Invention
