Description

Novel lamination diaphragm cutter structure

Technical Field

The utility model relates to a lithium battery technology field especially relates to a novel lamination diaphragm cutter structure.

Background

At present, the battery industry is rapidly developing, and the requirements and standards of batteries in the production process are higher and higher. The demand for production efficiency is also increasing. In the production process of the lithium battery, the anode and the cathode need to be separated by the polymer diaphragms, and the diaphragms need to be cut off after the whole coating of the battery core is finished.

The diaphragm cutting device in the prior art is characterized in that an electric heat conduction cutter is used for cutting off the diaphragm in the instant when the diaphragm is cut off, the diaphragm cutting device is unstable when the device operates, peculiar smell is generated due to the property of electric heating, the cutting effect is unsatisfactory, the diaphragm cannot be completely cut off at times, the notch is uneven, and poor cladding of the core bag and short circuit are caused when the core bag is laminated next time. The diaphragm hot knife heats the knife before cutting off, which causes obvious waste of efficiency.

To the technical problem, the utility model provides a novel lamination diaphragm cutter structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at prior art's defect, provide a novel lamination diaphragm cutter structure, utilize the sharpness of metal cutter incision mouth to cut off the diaphragm.

In order to realize the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel lamination diaphragm cutter structure, cutter structure includes cutting edge, blade, the cutting edge sets up in one side of blade, is equipped with the mounting hole at the both ends that are close to blade opposite side position, and the opposite side of blade is equipped with the several breach.

Furthermore, the cutting edge is of a chamfer structure, and the included angle between the chamfer inclined plane of the cutting edge and the axial plane of the cutting edge is 15-45 degrees.

Furthermore, the device also comprises a long-stroke high-speed cylinder structure, wherein the long-stroke high-speed cylinder is connected with the mounting hole.

Further, the cutter structure is made of a metal material.

Furthermore, the long-stroke high-speed cylinder structure is connected with the mounting hole through a fishbone joint.

Compared with the prior art, the utility model discloses used redesign's metal cutter, utilized the sharpness of metal cutter incision mouth to cut off the diaphragm.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

The utility model aims at prior art's defect, a novel lamination diaphragm cutter structure is provided.

Example one

The embodiment provides a novel laminated diaphragm cutter structure, as shown in fig. 1-4, the cutter structure comprises a blade 1, a blade body 2 and a cylinder structure 3.

Blade 2 is the rectangle structure, and one side on 2 rectangle structures long limits of blade is equipped with mounting hole 21, and the quantity of preferred mounting hole 21 is 2, sets up respectively in the position that is close to both ends on one side of long limit.

A socket 22 corresponding to the cylinder structure 3 is disposed on one side of the long side corresponding to the mounting hole 2, and the socket 22 is communicated with the mounting hole 21, so that one end of the cylinder structure 3 is disposed in the mounting hole 21 through the socket 22, thereby realizing control of the cutter structure.

A plurality of notches 23 are further formed in one side edge of the long edge of the cutter body 2, the number of the notches 23 can be set according to actual conditions, the notches 23 can be manufactured to reduce the weight of the cutter, and the cutter is convenient to mount.

The groove of installation cutting edge 1 is seted up to the opposite side on blade 2 long limit to make cutting edge 1 install in the inslot, cutting edge 1 is the chamfer structure, and the contained angle alpha of the axial plane of the chamfer inclined plane of cutting edge 1 and cutting edge 1 is 15-45, uses the cutting edge of chamfer structure to cut, and the sharpness is better, and can guide the direction of cutting off.

In this embodiment, the cutter structure is a metal material.

The air cylinder structure 3 is a long-stroke high-speed air cylinder structure, one end of the air cylinder structure 3 is connected with the cutter body 2 through a fishbone joint, and a certain buffering allowance is formed in the cutting process through the fishbone joint connection, so that stress is eliminated, and diaphragm wrinkles are reduced; the embodiment utilizes a long-stroke high-speed cylinder to physically push the cutter to cut off at a high speed.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
