Problems solved by technology

The current sampling method is to cut the pole piece on the coated pole piece to sample, and to test and measure the surface density of the surface active material of the pole piece. If the surface density is within the specified range, the prepared pole piece is qualified; However, in the production process of lithium-ion batteries, the uneven force during shearing and sampling often damages the coated pole pieces, causing them to be damaged and broken. This is a serious phenomenon of poor production process, resulting in Material waste and cost increase have been improved in various ways, but have not been effectively controlled

Abstract

The invention provides a battery electrode sampling jig which comprises a shearing die designed according to the sampling size; the shearing die is divided into a sampling upper die and a sampling lower die which are symmetrically arranged on the upper end part and the lower end part of a U-shaped supporting plate; the sampling upper die is sheathed with an upper die guide sleeve; the lower end of the sampling lower die is connected with a material receiving plate; a sampling punching cylinder is connected with the sampling upper die and fixed on the U-shaped supporting plate; and one side of the U-shaped supporting plate is provided with a handle, or the U-shaped supporting plate can be fixed on a fixing frame of a production line. The battery electrode sampling jig has the advantages of simple and convenient operation and stable sampling effect.

Description

technical field [0001] The invention relates to a battery electrode sampling jig, in particular to an electrode sampling jig in the production process of a lithium ion battery. Background technique [0002] Lithium-ion batteries are widely used in mobile communication equipment, notebook computers and other fields due to their advantages such as high working voltage, high volume and weight energy density, long life, low self-discharge rate, and no memory effect. [0003] In the production process of lithium-ion batteries, there is a coating process. The quality of the coated pole piece directly affects the performance of the battery. Therefore, it is necessary to inspect the pole piece during coating. The current sampling method is to cut the pole piece on the coated pole piece to sample, and to test and measure the surface density of the surface active material of the pole piece. If the surface density is within the specified range, the prepared pole piece is qualified; Ho...
