Button cell mounting equipment

Abstract

The invention relates to button cell mounting equipment, comprising a rack and a workbench on the rack, wherein the workbench is provided with a feed mechanism for transmitting a negative electrode cover, a lithium piece, a diaphragm, a positive electrode piece and a positive cover of a button cell assembly to mounting stations in turn, a transportation track for transporting the negative electrode cover, a lithium piece forming mechanism for forming the lithium piece on the negative electrode cover, a liquid-pouring mechanism for pouring electrolyte in the negative electrode cover, a sealingmechanism for packaging the cell and a clamp seat for locating the negative electrode cover on the transportation track, and the mechanisms are electrically connected with a main control circuit. In the invention, automatic feeding, mounting and sealing of the cell assembly are realized, the production efficiency and the product quality are improved, the labor intensity of workers are greatly reduced and the production cost is saved. The button cell mounting equipment is especially suitable for the requirements on producing lithium-manganese button cells in bulk, thereby improving the market competitive power of enterprises.

Description

technical field [0001] The invention belongs to battery production equipment, in particular to a button battery assembly equipment. Background technique [0002] Lithium manganese button battery is a disposable battery. Lithium manganese battery has high specific capacity, high voltage, small size, long storage time and good voltage stability. It is usually used in some relatively small and thin electronic products or backup memory of some products. in the power supply. [0003] Lithium-manganese button cells are generally composed of a negative electrode cover, a lithium sheet, a diaphragm, a positive electrode sheet, an electrolyte, and a positive electrode cover. Put the diaphragm on the lithium sheet, put the positive electrode sheet on the diaphragm, fill the positive electrode sheet with electrolyte, and finally put the positive electrode cover to seal. Among them, the positive electrode sheet is generally placed manually. Manually placing the positive electrode shee...

AI Technical Summary

Problems solved by technology

Among them, the positive electrode sheet is generally placed manually. Manually placing the positive electrode sheet not only slows down the feeding speed and low efficiency, but also the material of the positive electrode sheet is easily broken, resulting in a high scrap rate; and because the electrolyte needs to be filled several times during the assembly process, manual It is difficult to guarantee the interval between each injection

In addition, the battery needs to be packaged many times after the positive electrode sheet is manually placed. The quality of the battery seal is poor, it is easy to leak electrolyte, and it is prone to failure during use.
