Technical Field

The utility model relates to a Z-shaped laminated special-shaped battery special-shaped edge diaphragm cutting device, and belongs to the technical field of lithium battery manufacturing.

Background

At present, the most widely used lithium ion battery lamination machine is a Z-shaped battery lamination machine, and the lamination equipment forms a pole group by laminating a positive pole piece and a negative pole piece together through membrane unreeling and a series of pole piece positioning, taking and laminating actions, and the membrane is in a Z-shaped structure in the pole group, and the positive pole piece and the negative pole piece are separated by the membrane, so the lamination machine is called as the Z-shaped battery lamination machine. Because the diaphragm is rectangular, the diaphragm is still in a multi-layer rectangular shape after the Z-shaped lamination, and the pole group after the lamination of the device is in a rectangular structure. Due to the structure, even if the positive pole piece and the negative pole piece adopt the special-shaped structural piece, the pole group stacked by the device is still rectangular. At present, along with electronic equipment's further development, also higher and higher to heterotypic structure's battery demand, because heterotypic battery has special-shaped limit, the square utmost point group of common "Z" style of calligraphy lamination equipment preparation is difficult to satisfy the demand of heterotypic structure, therefore the application has received the restriction. In order to improve the adaptability of Z-shaped laminating equipment and solve the problem of processing the special-shaped edge diaphragm, a Z-shaped special-shaped laminated battery special-shaped edge diaphragm cutting device needs to be developed.

The utility model is realized by the following technical scheme:

the utility model provides a Z style of calligraphy lamination dysmorphism battery dysmorphism limit diaphragm cutting device promptly, includes the base, installs locating plate and limiting plate through the bolt on the base, is equipped with the spacing recess of laminating mutually with Z style of calligraphy lamination dysmorphism battery utmost point group profile on the locating plate, and the edge profile of limiting plate agrees with mutually with the edge profile of locating plate, and has the clearance between the two edge profiles, and the limiting plate upper end is equipped with the clamp plate.

The pole group with the diaphragm is placed in the limiting groove, the edge of the pole group is tightly attached to the inner wall of the limiting groove, the pressing plate compresses redundant diaphragms, and cutting equipment is used for cutting the redundant diaphragms along the gap between the edge outline of the limiting plate and the edge outline of the positioning plate. By using the utility model, redundant diaphragm parts of the stacked rectangular pole groups can be cut off, and the special-shaped pole groups meeting the design requirements can be conveniently manufactured.

The utility model is further improved in that trumpet-shaped flaring openings are arranged between the two ends of the edge outline of the limiting plate and the two ends of the edge outline of the positioning plate. This design facilitates the access of the cutting device.

The utility model is further improved in that the height of the upper end surface of the positioning plate is the same as that of the upper end surface of the limiting plate.

The utility model is further improved in that the positioning plate, the limiting plate and the pressing plate are made of bakelite plates or organic glass.

The utility model is further improved in that the pressure plate is controlled to lift by an air cylinder above the pressure plate. The piston rod of the air cylinder is connected with the pressing plate, and the lifting of the pressing plate is controlled through the air cylinder, so that the operation is convenient.

The utility model is further improved in that the limiting plate is provided with an arc-shaped notch. The design of arc breach is convenient for taking of utmost point group.

Compared with the prior art, the utility model has the beneficial effects that:
