Abstract

The utility model discloses a multifunctional electrode piece punching device, which can punch electrode pieces of various specifications. The multifunctional electrode piece punching device comprises a punching die (3), a pressing device (7), a POL controller (4) and a sensor (6), wherein the sensor (6) can sense electrode coating, and move according to the length of the electrode coating area, the POL controller (4) controls the punching die (3) to reasonably punch the electrode pieces according to the information received by the sensor (6). The utility model has the following advantages: the position of the sensor (6) is adjusted according to the electrodes of various specifications, and the electrode pieces of various specifications are punched maybe by the same pair of the punching dies (3), the manufacture cost of the device is reduced and the utilization rate of the device is improved.

Description

A kind of universal electrode sheet blanking units

Technical field

The utility model relates to a kind of used equipment, particularly a kind of device of die-cut pole piece when producing battery.

Background technology

When the lithium electrode sheet is die-cut; Die-cut side commonly used generally is the pole piece of the die-cut a kind of fixed dimension of a secondary die cutting die; But it is a variety of that the size of electrode slice has; Need a kind of electrode slice will make a secondary mould, increased the cost of exploitation different capabilities electricity core like this, cause each company to produce the limited of electric core specification again.

The utility model content

(1) the utility model technical problem that will solve

The utility model technical problem to be solved is the deficiency to prior art, and a kind of universal electrode sheet blanking units is provided, and reaches the pole piece that a secondary die cutting die can die-cut size arbitrary dimension within the specific limits.

(2) technical scheme of utility model

A kind of universal electrode sheet blanking units comprises die cutting die, POL controller, presser device and inductor; Said sensor is contained in the coating of unprocessed electrode, and the position can move according to the dispensing area length of electrode coating, through the PLC controller die-cut before the edge of a knife drop on the appropriate location of staying white region simultaneously with the back edge of a knife.Said die cutting die is contained in a side of presser device, and the preceding edge of a knife of said die cutting die is simultaneously die-cut with back one pole piece front end to last pole piece rear end respectively with the back edge of a knife.In the one-step punching process, the preceding edge of a knife of said die cutting die drops on same staying in the white region simultaneously with the back edge of a knife, and the part that explanation is cut away is for staying a part in the white region.It is fixing that said presser device can be pushed down the electrode coating, makes when die-cut, to be difficult for becoming flexible.

(3) beneficial effect

Compared with prior art; The technical scheme of the utility model has the following advantages: same secondary die cutting die can the different pole piece of die-cut lengthwise dimension; Reduced the manufacturing cost of equipment, improved usage ratio of equipment, for the battery of producing continuous different capabilities is carried out prerequisite.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, a kind of universal electrode sheet blanking units comprises die cutting die 3, presser device 7 and inductor 6; Said sensor 6 is contained in the coating of unprocessed electrode, and the position can move according to the dispensing area length of electrode coating, through PLC controller 4 die-cut before the edges of a knife 1 drop on the appropriate location of staying white region simultaneously with the back edge of a knife 2.Said die cutting die 3 is contained in a side of presser device 7, and the preceding edge of a knife 1 of said die cutting die 3 is simultaneously die-cut with back one electrode slice front end to last electrode slice rear end respectively with the back edge of a knife 2.In the one-step punching process, the preceding edge of a knife 1 of said die cutting die 3 drops on same staying in the white region simultaneously with the back edge of a knife 2.It is fixing that said presser device 7 can be pushed down the electrode coating, makes when die-cut, to be difficult for becoming flexible.

When the die-cut another kind of electrodes sized sheet of needs, need not change die-cut mould, only need move through changing sensor 6 positions according to the dispensing area length of electrode coating, let die-cut before the edge of a knife 1 drop on the appropriate location of staying white region simultaneously with the back edge of a knife 2.Before the rear end of the edge of a knife 1 die-cut last pole piece, the back edge of a knife 2 die-cut front ends of pole pieces afterwards, accomplish process after; Pole piece travels forward under driven by motor; When sensor respond to once more arrived the pole piece afterbody and stay white between the time, pole piece stops to flow, it is die-cut to carry out the second time.The afterbody of the preceding edge of a knife 1 a die-cut last pole piece is accomplished the die-cut of last pole piece.

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

Claims

1. a universal electrode sheet blanking units is characterized in that: comprise die cutting die (3), presser device (7), PLC controller (4) and inductor (6); Said sensor (6) can be responded to the electrode coating that sends, and the position can be moved according to the dispensing area length of electrode coating.

2. universal electrode sheet blanking units according to claim 1; It is characterized in that: said die cutting die (3) is contained in a side of presser device (7), and the preceding edge of a knife (1) of said die cutting die (3) is simultaneously die-cut with back one pole piece front end to last pole piece rear end respectively with the back edge of a knife (2); In the one-step punching process, the preceding edge of a knife (1) of said die cutting die drops on same staying in the white region simultaneously with the back edge of a knife (2).
