Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0028] refer to Figure 2-7 As shown, the present invention discloses a battery rubber die-cutting cutter assembly, including a first cutter, a second cutter, a third cutter, a fourth cutter and a fifth cutter. Wherein, the first knife cutting obtains the first cutting line m, and the first cutting line includes the first arc cutting line m 0 ;The third knife cutting obtains the third knife line n, and the third knife line includes the straight edge line n 0 . During the die-cutting process, the straight edge line n 0 and the first arc cutter line m 0 intersect. For conventional cutter assemblies, refer to Figure 1-Figure 2 , the first cutting line m and the third cutting li...

Abstract

The invention discloses a cutting knife assembly and a die cutting control method of battery glue die cutting. The cutting knife assembly comprises a first cutting knife, a second cutting knife, a third cutting knife, a fourth cutting knife and a fifth cutting knife, the cutting knife assembly is characterized in that a first knife line is obtained by the first cutting knife cutting, and the firstknife line comprises a first arc knife line; a third knife line is obtained by the third cutting knife cutting, and the third knife line comprises a straight blade line; and in the die cutting process, the straight blade line intersects with the first arc knife line. According to the cutting knife assembly, the independent adjustment of associated sizes is realized, the original unstable associated sizes all within the tolerance range can be ensured, the difficulty of adjusting a machine is reduced, and the product yield and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of die-cutting, in particular to a cutter assembly and a die-cutting control method for battery rubber die-cutting. Background technique [0002] The battery glue is usually composed of five layers of materials, from top to bottom, it is PET release paper, the first Mylar, easy-to-pull glue, the second Mylar and the backing paper. The preparation of battery glue is prepared by a die-cutting process, which usually includes the following steps: (1) Firstly, the protective film is loaded as a carrier, and the peeling paper is covered on the protective film, and then the first Mylar is covered on the peeling paper, the first The cutting knife cuts out the shape of the first Mylar part, drains the waste and covers it with easy-to-pull glue; (2) the second cutter cuts out the shape of the second Mylar part, drains the waste and covers it with easy-to-pull glue; (3) The third cutter cuts out the entire shape of th...
