Problems solved by technology

During this process, the lithium sheet is very easy to stick to the knife and stick to other materials that it touches, making it difficult to form and peel off. It can be seen that the current lithium sheet processing and battery assembly methods are basically still in the backward manual operation stage. , low efficiency, high overall cost

Embodiment Construction

[0012] The gist of the present invention is to provide a lithium sheet automatic processing equipment with high degree of automation and high production efficiency, which is applied to the manufacture of lithium batteries with metal lithium as the negative electrode. When manufacturing lithium batteries, the metal lithium Li sheet, which is the negative electrode active material of the battery, must be attached to the inside of the battery steel case or rolled into a certain shape before being placed inside the battery case. However, because the metal lithium sheet is very soft, it is easy to bond. on various materials. Therefore, when making the lithium battery, it is difficult to mechanize and automate the cutting, crimping, positioning, and shelling of the negative metal lithium. The problems to be solved in the present invention are: use methods such as gas (liquid) dynamic and mechanical transmission, cooperate with suitable molds and fixtures to realize the automation an...

Abstract

The invention discloses an apparatus for processing a lithium piece. The apparatus comprises a frame and a machine table on the frame, a controlled atmosphere chamber is arranged on the table, the table covered by the controlled atmosphere chamber is sequentially equipped with a lithium piece winding up roller, a lithium piece feeding device, a lithium piece cutting device, as well as a lithium piece reeling device and a steel shell conveying device which are paratactic, besides, the table is further provided with a device for putting the lithium piece into the steel shell, a lithium piece rolling device, a discharging device and the like, wherein, the controlled atmosphere chamber is connected with the machine table in a hermetic seal manner and the chamber is full of dry air or dry gas which is inert in relation to lithium metal. The apparatus effectively solves the problems of the traditional manual processing course such as easy sticking of the lithium piece to a knife, difficult forming and stripping, low manual efficiency and high comprehensive cost. The apparatus significantly reduces the labor intensity of workers, greatly improves the production efficiency, and effectively reduces the comprehensive cost of the product.

Description

technical field [0001] The invention relates to a lithium sheet processing device, in particular to a fully automatic reel processing device for lithium sheets used in lithium batteries with metal lithium as the negative electrode. Background technique [0002] The lithium battery with metal lithium as the negative electrode is a high-energy battery developed only in the last century. It has been widely used for its advantages of high open circuit voltage, high specific energy, wide operating temperature range, stable discharge voltage, and low self-discharge rate. Various fields, especially aerospace, military, long-life instrumentation, logistics tracking, automotive electronics and other fields. Lithium metal, as the active material of the battery, has very soft physical properties and very active chemical properties, so that the processing of lithium sheets is severely restricted, so that lithium sheet processing devices are still rarely seen in the market, and no relate...
