Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] like Figure 1 ~ Figure 3 As shown, a lug die-cutting method for an intercoated pole piece includes a material guide assembly 100 for pulling the intercoated pole piece coil, a detection assembly 200 for detecting the intercoating position of the intercoated pole piece, A die-cutting assembly 300 for die-cutting the intercoated pole pieces introduced by the material guide assembly 100, and a blanking assembly 400 for pulling and conveying the die-cut pole pieces;

[0033] The tab die-cutting method comprises the following steps:

[0034] S1, conveying the intercoated pole piece correction guide material through the material guide assembly 100;

[0035] S2, after being transported to the designated position, the position detection of the intercoating position of the intercoating pole piece is carried out by the detection component 200;

[0036] S3, transportin...

Abstract

The invention relates to the technical field of pole piece die cutting, in particular to a tab die cutting method for an inter-coating pole piece. A material guide assembly used for pulling an inter-coating pole piece roll material, a detection assembly used for detecting the inter-coating position of the inter-coating pole piece, a die cutting assembly used for carrying out die cutting on the inter-coating pole piece introduced by the material guide assembly, and a discharging assembly used for pulling and conveying the die-cut pole piece are involved in the tab die cutting method. According to the tab die cutting method, a large-compaction-density process can be adopted, so that the capacity of a single battery cell is improved; a large-size cutter mechanism is omitted, so that dust and burrs are reduced, the quality of the pole piece is effectively improved, and the safety performance of a battery is improved; and the large-size cutter mechanism is omitted, so that the use cost of equipment is remarkably reduced, thereby greatly reducing the manufacturing cost of a battery cell.

Description

technical field [0001] The invention relates to the technical field of pole piece die-cutting, in particular to a tab die-cutting method for an intercoated pole piece. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] As an important part of the lithium battery, the pole piece plays a vital role in the performance of the battery. The pole piece is made by coating the pole powder material on both sides of the base materia...
