Automatic lifting and feeding method for battery pole piece die cutting

Abstract

The invention discloses an automatic lifting and feeding method for battery pole piece die cutting. The automatic lifting and feeding method comprises a feeding module, a displacement difference compensating module, a floating module, a constant-tension roll buffering device and PLCs (programmable logic controllers), wherein materials are fed by the automatic feeding module; a photoelectric sensorand one PLC controls the amount of the fed materials; the displacement difference compensating module automatically adjusts the height of incoming materials and sends the incoming materials into a die cutting process; the floating module and the constant-tension roll buffering device reels the materials; the components are serially connected and combined and are controlled by the other PLC to docooperative work so as to play an automatic lifting and feeding role. By the automatic lifting and feeding method, battery pole pieces or flexible materials can be quickly and accurately delivered, jamming and sticking phenomena in the die cutting process are avoided, the manufacturing cost is low, suitability for mass production is achieved, and the reliability is strong; by the automatic liftingand feeding method, designed modules can be converted into real objects, the manufacturing cost is low, and the performance is stable; the automatic lifting and feeding method can be conveniently implanted into any equipment for battery pole piece die cutting or flexible material die cutting, and is wide in application.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing and the industry using roll-shaped flexible materials, in particular to an automatic lifting and feeding method for die-cutting battery pole pieces during the production die-cutting process of lithium battery pole pieces. Background technique [0002] Lithium batteries have the advantages of good safety performance, small thickness, light weight, small internal resistance, easy model replacement, and high energy density, so they are widely used in electric vehicles, energy storage power supplies, digital products and other fields. However, a large number of battery pole pieces are used in the manufacturing process of lithium battery cells, so the batch productivity of battery pole pieces is directly related to the manufacturing capacity of lithium battery manufacturers, and battery pole pieces are often formed by die-cutting at present, so die-cutting Equipment is one of the key equipm...
