Abstract

The utility model relates to the field of battery processing mechanical equipment and particularly relates to a mirrored slice blanking device. The mirrored slice blanking device comprises a blanking mold (2), a plate pressing device (3), a PLC (Programmable Logic Controller) (4) and a striped electrode coating (1), wherein the striped electrode coating (1) is blanked into two mirrored electrode slices in one time through the blanking mold (2) by the PLC (4). The shape of the edge of the blanking mold (2) is shaped in the way that the middle is a rectangle, two sides of the rectangle are respectively provided a blanking line, and one blanking line and the other blanking line are opposite in direction. The mirrored slice blanking device disclosed by the utility model has the advantages that two slices can be simultaneously blanked by the blanking mold in one time, so that the production efficiency is greatly increased; and copper (aluminum) foil materials can be better saved, a novel slice blanking manner is a mirrored slice blanking manner, and then, copper (aluminum) foils wasted during single slice blanking can be further utilized.

Description

A kind of mirror image slicing device

Technical field

The utility model relates to a kind of used accessory, particularly a kind of novel slicing device when producing battery.

Background technology

In the production technology of lithium battery, wherein the production technology of electrode slice is one very important operation, and the production technology of general electrode slice all comes punching press to realize finishing with bicker.Existing bicker generally once can only be cut a slice production, and inefficiency.

The electrode slice of lithium battery is generally made by copper (aluminium) foil material, and at present copper (aluminium) paper tinsel is very expensive on market, and general bicker is when die-cut, and the unnecessary material waste especially severe at the lug position is so cost is very high.

The utility model content

(1) the utility model technical problem that will solve

Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel slicing device is provided.

(2) technical scheme of utility model

The technical solution of the utility model: comprise that the electrode behind die cutting die, presser device and the itemize is coated with, the PLC controller is by the pole coating disposable pole piece that be cut into two mirror images of described die cutting die after with itemize, rectangle in the middle of the edge of a knife of described die cutting die is shaped as, both sides one side respectively has a tangent line, and one tangent line is at the opposite direction place of another tangent line, and the waste material after this device is die-cut greatly is less than a slice and singly cuts waste material after die-cut.The length at the coating place of the electrode coating behind the described itemize is the length at the coating place of two lithium battery pole pieces, and blank space is the length of single battery sheet lug.

Described die cutting die is fixed on a side of presser device, because be that the coating place is the length at the coating place of two lithium battery pole pieces, so presser device is longer than general presser device.

(3) beneficial effect

The beneficial effects of the utility model: enhance productivity, die cutting die once can be cut simultaneously two sheets and can greatly enhance productivity; Can better saving copper (aluminium) foil material, this Novel cutting sheet mode is the mirror image section, can more monolithic be cut copper (aluminium) the paper tinsel utilization of waste.

Embodiment

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, a kind of mirror image slicing device, comprise that the electrode behind die cutting die 2, presser device 3, POL controller 4 and the itemize is coated with 1, PLC controller 4 by described die cutting die 2 with the pole coating 1 disposable pole piece that is cut into two mirror images behind the itemize, rectangle in the middle of the edge of a knife of described die cutting die 2 is shaped as, both sides one side respectively has a tangent line, and tangent line is at the opposite direction place of another tangent line.Waste material 7 after this device is die-cut greatly is less than a slice and singly cuts waste material after die-cut.The length at the coating place 6 of the electrode coating 1 behind the described itemize is the length at the coating place 6 of two lithium battery pole pieces, and blank space 5 is the length of single battery sheet lug.Described die cutting die 2 is fixed on a side of presser device 3, because be that coating place 6 is the length at the coating place 6 of two lithium battery pole pieces, so presser device 2 is longer than general presser device.

During the machine operation, when the electrode smear 1 behind the itemize is transported to the position of presser device 3, conveyer belt stops to carry, the PLC controller passes the information control presser device 2 come according to inductor and pushes down the conveying electrode coating 1 of coming, 2 pairs of blank spaces of the die cutting die of one side of presser device 35 are carried out die-cut, disposablely itemize rear electrode sheet is cut into the pole piece of two mirror images, successively circulation.

When in sum, above-mentioned execution mode is not to be restricted execution mode of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation are all at technology category of the present utility model.

Claims
