Problems solved by technology

The traditional operation method is to manually cut the positive and negative electrodes into sections according to the coating and uncoated areas (cutting large pieces), and then use the knife die to make individual monomers on the press. The old method Complicated procedures, high labor intensity, low die life (≤20,000 times), low efficiency (≤8 times / minute), difficult positioning, easily damaged pole pieces, poor product consistency, etc., are used to manufacture small-capacity The battery is barely enough, but for the new type of large-capacity power battery, due to its thick pole piece (0.25-0.35mm), there are many batteries connected in series and parallel, which requires higher consistency of each monomer, and the traditional manufacturing method is adopted Its efficiency, product performance, and die life (≤10,000 times) are even more difficult to deal with

Abstract

The invention provides a continuous sheet-making machine, relating to a battery pole piece system. The sheet-making machine comprises a rack, a moulding mechanism as well as a feeding mechanism and a traction mechanism which are at the front and rear of the moulding mechanism, a cutting mechanism is also arranged between the moulding mechanism and the traction mechanism, the lower part of the cutting mechanism is provided with a take-up mechanism, a winding up mechanism and a tension mechanism are arranged in front of the feeding mechanism, and further the sheet-making machine also can comprise a material incoming mechanism. The continuous punching sheet-making machine is applicable to automatic sheet-making of power battery pole piece in high thickness material and has the advantages of wide application range, high production efficiency, stable product performance, long mould service life and low operating cost.

Description

technical field [0001] The invention relates to a battery pole piece manufacturing system, in particular to a continuous punching machine for die punching. Background technique [0002] The stacked lithium battery is made of multi-layer positive and negative pole pieces. These pole pieces are always cut from the whole pole piece that has been coated and rolled. The traditional operation method is to manually cut the positive and negative electrodes into sections according to the coating and uncoated areas (cutting large pieces), and then use the knife die to make individual monomers on the press. The old method Complicated procedures, high labor intensity, low die life (≤20,000 times), low efficiency (≤8 times / minute), difficult positioning, easily damaged pole pieces, poor product consistency, etc., are used to manufacture small-capacity The battery is barely enough, but for the new type of large-capacity power battery, due to its thick pole piece (0.25-0.35mm), there are ...
