An automatic equipment for flanging forming of negative electrode sheet

Abstract

The invention relates to the field of manufacturing of thermal batteries, in particular to automatic equipment for flanging formation of negative pole pieces. The automatic equipment comprises a supporting and lifting mechanism, a glove box, an automatic restoration mold, a flanging station, a high-precision numerical-control rotary table, a pre-pressing station, a demolding station, a formation station, and a transferring and stacking robot, wherein the supporting and lifting mechanism and the high-precision numerical-control rotary table are arranged at the bottom of the glove box, the automatic restoration mold is arranged on a positioning base of the high-precision numerical-control rotary table, and the positioning base has a 0-degree storage position, a 90-degree storage position, a180-degree storage position and a 270-degree storage position; the supporting and lifting mechanism is arranged below the automatic restoration mold; the flanging station, the pre-pressing station, the demolding station, and the transferring and stacking robot are arranged at the top of the glove box; the flanging station, the pre-pressing station and the demolding station are separately arrangedover a 90-degree station, a 180-degree station and a 270-degree station of the high-precision numerical-control rotary table; and the formation station is fixed to one side of the high-precision numerical-control rotary table. According to the automatic equipment, flanging formation of negative pole pieces can be automatically completed through program control, and the manufacturing efficiency ofthermal batteries is improved.

Description

technical field [0001] The invention relates to the field of thermal battery manufacturing, in particular to an automatic equipment for flanging a negative electrode sheet. Background technique [0002] A thermal battery is a thermally activated primary reserve battery. Generally, the electric stack composed of several single cells connected in series and in parallel together with the heating sheet is put into the combination case, and the electric stack is connected to the terminal on the battery cover through the drain strip, and the whole battery is composed of electric stack, activation mechanism, combination The shell and combined cover are welded by argon arc welding. A single battery is composed of a positive electrode, an electrolyte, and a negative electrode. The negative electrode is an important part of the single battery. With the wide application of thermal batteries in modern weapons, the demand for the negative electrode is also increasing. [0003] The neg...

Problems solved by technology

[0003] The negative electrode sheet is made of a combination of LiB alloy sheet and nickel sheet. At present, the combination of LiB alloy sheet and nickel sheet is completed by manual operation. Because LiB alloy sheet is flammable in the air, manual operation is more dangerous. At the same time, manual operation The efficiency is low and the degree of automation is not high. How to improve the production efficiency of the negative electrode sheet and improve the consistency of the combined pressing of the LiB alloy sheet and the nickel sheet is a technical problem to be solved by those skilled in the art.
