Pole piece laser cutting machine

Abstract

The invention discloses a pole piece laser cutting machine. The machine comprises a base frame part, a laser cutter, a cutting manipulator part, a control system and at least a piece feeding component, wherein the cutting manipulator part is used for driving the laser cutter; each piece feeding component comprises a material clamping manipulator part, a feeding fixed-length part and an emptying part; the cutting manipulator part and the material clamping manipulator part are installed on the base frame part; the feeding fixed-length part is arranged between the material clamping manipulator part and the emptying part; and the control system is connected with the cutting manipulator part, the material clamping manipulator part and the feeding fixed-length part. The machine has the following beneficial effects: the machine realizes the piece preparation processes of the lithium ion batteries or super capacitors by adopting the laser technology, can solve the problem that the pole pieces are easy to deform and have bigger burrs as the traditional cutting processes are adopted in the prior art, simultaneously improves the piece preparation process quality under the control of the control system and increases the yield.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a pole piece laser cutting machine. Background technique [0002] In the production process of lithium-ion batteries and supercapacitors, the production process of the pole piece is very critical. In the current production process of the pole piece, equipment such as knife die punching machine, gold die punching machine, and roll cutting machine are usually used to realize the pole piece. However, the pole piece is made of thinner aluminum foil and copper foil. When the piece is made by the above cutting equipment, it is easy to wrinkle or deform the pole piece, which will cause the flatness of the cut pole piece to fail to meet the requirements and be scrapped. Moreover, both sides of the pole piece have a coating layer. After the above cutting equipment is used to make pieces, the pole pieces have large burrs and are easy to drop powder, resulting in low pass rate and many waste produc...

Problems solved by technology

[0002] In the production process of lithium-ion batteries and supercapacitors, the production process of the pole piece is very critical. In the current production process of the pole piece, equipment such as knife die punching machine, gold die punching machine, and roll cutting machine are usually used to realize the pole piece. However, the pole piece is made of aluminum foil and copper foil with a small thickness. When the piece is made by the above cutting equipment, it is easy to wrinkle or deform the pole piece, which will cause the flatness of the cut pole piece to fail to meet the requirements and be scrapped.

Moreover, both sides of the pole piece have a coating layer. After the above cutting equipment is used to make pieces, the pole pieces have large burrs and are easy to drop powder, resulting in low pass rate and many waste products in the production process, resulting in low production efficiency and waste of materials. Mass production of lithium-ion batteries and supercapacitors has serious implications
