Abstract
The utility model belongs to the technical field of lithium battery and provides a pre-bender for tab of lithium battery. The pre-bender for tab of lithium battery comprises a base, a cylinder, a bending drift, a bottom plate and a bending plate which are provided on the base. The bending drift is provided right below the cylinder. The bottom plate is provided below the bending drift. The bending plate is provided on one side surface of the bottom plate and projects from the surface of the bottom plate for placing the battery. The pre-bender for tab of lithium battery according to the utility model has the following advantages: mechanized operation in most process, high production efficiency, low manufacturing cost, convenient operation, shortened exposed length of the tab, and improved battery capacity.
Description
Technical field
The utility model relates to the lithium battery processing apparatus, relates in particular to the pre-bending device of a kind of lithium battery pole ear.
Background technology
Lithium ion battery is the portable chemical power source that a kind of volume is little, energy density is high, is widely used in the digital electric field.The lug bending problem of lithium battery is that all battery manufacturing factories are perplexed, and directly influence the quality and the harvest rate of product, and traditional handicraft is a manual folding lug after the cell polar ear welded cover plate, this labor intensity is big, and lug leaks outside longer, influences the lifting of battery capacity.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device that can bend lithium battery pole ear in the mechanization mode is provided.
For achieving the above object, the technical solution adopted in the utility model is:
The pre-bending device of a kind of lithium battery pole ear, comprise support and be arranged on cylinder, Bending punch, base plate and flap on the support, Bending punch is arranged under the cylinder, and base plate is arranged on Bending punch below, and flap is arranged on the side of base plate and protrudes in the surface that base plate is placed battery.
On the surface of described base plate placement battery, also be provided with left plate washer and right plate washer.
Also further comprise connecting plate, described Bending punch comprises anode ear Bending punch and negative electrode lug Bending punch, is fixed in abreast on the connecting plate, and connecting plate is connected the cylinder lower end.
Described staking punch lower end side is a right-angled trapezium, and described folding class plate is provided with the V-notch that cooperates with staking punch.
The beneficial effects of the utility model: most of process is carried out mechanized operation, the production efficiency height; Low cost of manufacture, easy to operate; And can shorten the lug length that leaks outside, promote battery capacity.
