Background technique

Lithium-ion 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. In the manufacturing process of lithium-ion battery cells, a large number of battery pole pieces need to be used, so the batch productivity of battery pole pieces is directly related to the manufacturing capacity of lithium-ion battery manufacturers, and the current die-cutting of battery pole pieces, so die-cutting Cutting equipment is the key equipment in the lithium-ion battery industry.

The traditional method of battery die-cutting equipment is to use laser die-cutting process, which is fast but has many burrs. Therefore, a new type of metal die-cutting equipment is slowly replacing traditional equipment. This equipment is basically burr-free and improves the quality of battery pole pieces to a higher level. However, this equipment has not yet been matured and popularized in the market. The utility model is a cutting device developed for the key function points of hardware die-cutting equipment.

Contents of the invention

The purpose of the utility model is to develop and design a stable and convenient battery pole piece cutting device for the shortcomings of battery pole piece hardware die-cutting equipment.

detailed description

The utility model will be described in further detail below in conjunction with examples and accompanying drawings, but the implementation of the utility model is not limited thereto.

As shown in Figure 1 or 2, the battery pole piece cutting device of the present invention includes a PLC, a photoelectric sensor, a feeding module, and a cutting module. Cylinder 1 and two linear bearings 2 with two guide rods 15 are fixed on the bracket beam 3, and are combined with three connecting plates 5 of the bracket and two rubber-coated rollers 7 to form the upper part of the feeding module. The rubber-coated roller 7 and the bearing 16 and the driving motor 10 are fixed on the bracket fixing plate 8 to form the lower part of the feeding module; another cylinder 1 and linear guide rail 9 are fixed on the bracket angle plate 11, and are connected to the cutting upper knife 13 and the spring bezel 6 through the bracket knife template 12 Combined into the upper part of the cutting module, the lower cutting knife and the material pallet 4 are fixed on the bracket angle plate 11 to form the lower part of the cutting module. The bracket fixing plate 8 fixes the bracket angle plate 11, the bracket beam 3, the bearing 16 and the driving motor 10 in corresponding positions respectively, thereby forming an integral module.

The photoelectric sensor is installed under the material pallet 4 to sense the length of the incoming material and sends a signal to the PLC. After receiving the signal, the PLC instructs the drive motor 10 to suspend work, so as to stop the feeding module from feeding and instruct the cylinder on the cutting module to work. achieve the purpose of cutting. After cutting, the induction switch on the cylinder gives the PLC signal to allow the PLC to point to the drive motor 10 to work and supply materials, so that automatic cycle work can be formed.

The above shows and descriptions are preferred implementations of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in the form of Other concrete forms implement imitation.
