Description

Small poly battery tab step cutter device

Technical Field

The utility model relates to the technical field of battery processing, in particular to a step cutter device for a small polymer battery tab.

Background

Small poly-batteries refer to small polymer batteries. In the prior art, the tab cutter device of the small polymer battery is similar to the aluminum shell battery, and a rotary disc type cutter device is adopted. The defects of the prior art are as follows: the positive and negative lugs are cut at two different stations respectively (the positive and negative lugs are different in length), although the step lengths can be realized by adjusting the handle positions of respective adjustable cylinders, the device is realized on a rotary turntable, the structure is not complex, but the cutting is completed by a set of matched driving device, and the occupied space is relatively large. In addition, if other non-rotary disc cutting modes are adopted, the clamp with the battery can move left and right linearly, the double knives respectively cut the lugs without moving or the clamp with the battery is not moving, and the double knives respectively cut the lugs by moving left and right linearly. But all have the defects of relatively complex structure, more adjusting links, difficult operation and the like.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the tab cutting knife device which is simple in structure and convenient to operate.

The technical scheme of the utility model is as follows:

the utility model provides a little battery tab step cutters, it includes base, lower blade holder, goes up blade holder and cylinder, install down the blade holder through the mount pad on the base, install the cylinder on the base and lie in the position of blade holder rear side down, the push rod of cylinder has last blade holder through the leg joint, and lower step cutter is installed to lower blade holder rear end, goes up the lower step cutter that the blade holder corresponds blade holder rear end face down and installs the upper step cutter, the thick right side in lower step cutter left side is thin and the upper step cutter is then the thin right side in left side thick (be the step appearance), and two cutters correspond to set up and make two utmost points ear that they can correspond little battery carry out asymmetric cutting.

Further, on the mount pad and be located down the tool rest both sides and install left stopper of width and the right stopper of width respectively, form V type breach between the left stopper of width and the right stopper of width, do benefit to and gather the battery for a short time and lead-in.

Further, high left stopper and high right stopper are installed respectively to width left stopper and width right stopper top surface, and high left stopper and high right stopper can support the blade holder for go up the blade holder stroke and receive the restriction.

Further, install linear slide rail on the base, linear slide rail's moving part is connected with last blade holder for go up the blade holder and can move along linear slide rail.

Furthermore, the lower step cutter and the upper step cutter are both made of zirconia ceramic materials. Because the small polymer battery is electrified when the tab is cut, if a metal blade is adopted for cutting, short circuit and even explosion are easily caused.

The utility model has the beneficial effects that: simple structure, convenient to use adopts the cutter of a pair of non-planar to cut to the length utmost point ear of little polybattery, and work efficiency is high and only need a cylinder to drive, does benefit to follow-up maintenance and maintenance.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

as shown in fig. 1 and 2, a little poly battery utmost point ear step cutters, it includes base 1, lower blade holder 2, goes up blade holder 9 and cylinder 7, install lower blade holder 2 through the mount pad on the base 1, install cylinder 7 on the base 1 and lie in the position of blade holder 2 rear down, the push rod of cylinder 7 has last blade holder 9 through the leg joint, lower step cutter 11 is installed to lower blade holder 2 rear end, goes up blade holder 9 and installs upper step cutter 12 corresponding to lower step cutter 11 of lower blade holder 2 rear end face, lower step cutter 11 left side is thick right side and upper step cutter 12 is thin right side left side is thick.

And a left width limiting block 3 and a right width limiting block 5 are respectively arranged on the two sides of the lower tool apron 2 on the mounting seat, and a V-shaped notch is formed between the left width limiting block 3 and the right width limiting block 5.

And a left height limiting block 4 and a right height limiting block 6 are respectively arranged on the top surfaces of the left width limiting block 3 and the right width limiting block 5.

The base 1 is provided with a linear slide rail 8, and a moving part of the linear slide rail 8 is connected with an upper tool apron 9.

The lower step cutter 11 and the upper step cutter 12 are made of zirconia ceramics.

The working principle is as follows: placing a small polymer battery 10 on a lower cutter holder, adjusting a width right limiting block 5 and a width left limiting block 3, adjusting a height right limiting block 6 and a height left limiting block 4, and adjusting the front and back positions of the two height limiting blocks to mainly meet the size requirement of the process on a battery tab; after the limiting blocks are adjusted, the air cylinder 7 is started to drive the upper step cutter 12 to move downwards along the direction of the linear slide rail 8, and under the combined action of the upper step cutter 12 and the lower step cutter 11, the positive and negative lugs of the battery are cut into step-shaped lugs (long lugs and short lugs) required by a customer.

The foregoing embodiments and description have been presented only to illustrate the principles and preferred embodiments of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as hereinafter claimed.
