Description
Technical field
The utility model category lithium battery technology field, more particularly to a kind of lithium battery pole slice for preventing lug from turning over pleat.
Background technology
At present in the production process of lithium ion battery, lug shaping uses laser incision technology, and laser incision technology passes through laser
The foil of pole piece both sides is left white and cuts into lug, but due to pole piece coating area and both sides are left white in nipping process calendering rate
Difference, coating area is caused stress to be present with area is left white, and the foil thickness that lithium battery is commonly used is below 20um, therefore pole piece exists
Laser is cut with rolling step, and lug easily turns over pleat from upper end, especially turns over pleat at lug upper end vertex, so as to the production influenceed
Efficiency and yields.
Chinese patent CN202103134U, which is disclosed, prevents lug Fan Zhe mechanisms, by smoothing portion, tape transport deflector roll, fixed support
Composition, the portion of smoothing be located at the entering with tangency location of tape transport deflector roll, and when lug enters tape transport deflector roll, the work of guiding is played in the portion of smoothing
With when lug is by smoothing gap between portion and tape transport deflector roll, smoothing portion and lug pressed into tape transport deflector roll, while it also has
There is flattening-out lug, although this structure can mitigate lug and turn over pleat, effect is unsatisfactory.
Chinese patent CN106003842A discloses lug flattening device, including the support that is connected with carrying roller and is arranged on
Hairbrush on support, when lug passes through carrying roller, lug is smoothed by hairbrush, lug is bonded carrying roller, so as to avoid
The phenomenon that broken belt or lug caused by the tear of lug root come off, but lug in subsequently by carrying roller and winding process according to
Pleat can so be turned over.
Chinese patent CN206022517U discloses a kind of winding type lithium battery pole piece of anti-lug fold, including pole piece sheet
Body and in pole piece body side by being cut by laser the lug that forms, offer and cut along the length direction of lug on the lug
Seam, can be achieved the effect of preventing and treating lug fold and turnover, but can not still solve lug and easily turn over pleat from upper end, especially from pole
The problem of pleat being turned at ear upper end vertex.
Utility model content

The lug formed, it is characterised in that the lug is provided with least 3 reinforcement impressions along short transverse, and the impression of strengthening is along pole
Ear width is equally spaced, and it is 1~3mm that outermost, which strengthens impression and the gap of lug upper end vertex,.
Described one end for strengthening impression is located at the upper end of lug, the other end away from lug and pole piece body 2~4mm of junction,
The width for strengthening impression is 0.2~1mm.
The reinforcement impression is process using patterned structure.
The patterned structure includes carry-over pinch rolls and knurling rolls, and the knurling rolls are externally provided with close-connected roller set A vertically
B is covered with roller, the roller set A surfaces are surrounded by the protective layer of anti-scratch pole piece, and the roller set B surface is provided with decorative pattern, and the decorative pattern is
It is raised to equally distributed strip that B axle is covered along roller.
Patterned structure working method：During gap of the pole piece through carry-over pinch rolls and knurling rolls, the position of roller set B and lug
Corresponding, roller set A is corresponding with the position of pole piece body, and the strip protruding pattern of roller set B surface, which is stamped on lug, to be formed
Strengthen impression.
As shown from the above technical solution, the utility model strengthens impression to increase the intensity of lug by being set on lug,
So as to prevent lug from turning over pleat, production efficiency and yields are improved.
