Because negative electrode lug gives a discount the battery of short circuit, its core is non-defective unit, and battery is directly scrapped and not only caused product and lead directly to
The reduction of rate, also result in a large amount of wastes of resource simultaneously, improves production cost, therefore negative electrode lug discounting battery is controlled
Fixture has important Research Significance.
Currently for staying Copper Foil and Copper Foil of crumpling causes negative electrode lug to give a discount to be difficult to control.Especially cross roller mistake in up- coiler
Cheng Zhong, can increase negative electrode lug and give a discount, have a strong impact on battery quality and first-pass yield.
Utility model content
The purpose of this utility model is to provide a kind of rectangular lithium ion battery negative electrode lug forming devices, and this device is to negative pole
The moulding effect of ear is good, can be effectively improved because of scrapping that negative electrode lug discounting causes, improve and produce first-pass yield.
For achieving the above object, the utility model employs technical scheme below：Including being fixed on laser cutting machine
Moulding rubber roll, the top of described moulding rubber roll is arranged in parallel prismatic pressure roller and fixing rubber roll, described prismatic pressure roller and fixation
Rubber roll is coaxially disposed, and prismatic pressure roller and fixing rubber roll are formed under the driving of elevating mechanism and contacted with moulding rubber roll or separate
Two states, described prismatic pressure roller includes roll body and is uniformly arranged on the wedge angle on roll surface along roll body circumference.
Described prismatic pressure roller and fixing rubber roll are arranged on stationary roller shaft, and prismatic pressure roller is set respectively with fixing rubber roll
Put two, described prismatic pressure roller is located at two side positions, and described fixing rubber roll is centrally located.
Described stationary roller shaft is fixed on pressing roller holder by roller frames, and described pressing roller holder is included positioned at moulding glue
Cross bar on the upside of roller and the column being located at moulding rubber roll side, the top phase of described cross bar and column is fixed.
Described elevating mechanism includes the lift controil valve being arranged on pressing roller holder and connects pressing roller holder and roll shaft
The elevating lever of frame, one end of described elevating lever is fixedly connected with roller frames, and the other end of elevating lever passes perpendicularly through cross bar, and is rising
The direction that the control lower edge cross bar of fall control valve limits moves up and down, to drive prismatic pressure roller and fixing rubber roll and moulding rubber roll phase
Contact or separation.
Its section of wedge angle on described prismatic pressure roller roll surface is triangular in shape.
As shown from the above technical solution, the utility model compresses pole piece by the cooperation of fixing rubber roll and moulding rubber roll,
By the cooperation of prismatic pressure roller and moulding rubber roll, negative electrode lug is carried out moulding, it is to avoid the electricity being caused due to the discounting of negative electrode lug
Pond short circuit phenomenon, significantly improves the discounting rate of negative electrode lug, improves the quality of battery, improve production first-pass yield simultaneously.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model prismatic pressure roller.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further：
A kind of rectangular lithium ion battery negative electrode lug forming devices as shown in Figure 1 and Figure 2, including being fixed on laser cutting machine
On moulding rubber roll 1, the top of moulding rubber roll 1 is arranged in parallel prismatic pressure roller 2 and fixing rubber roll 3, prismatic pressure roller 2 and fixing glue
Roller 3 is coaxially disposed, and prismatic pressure roller 2 and fixing rubber roll 3 are formed under the driving of elevating mechanism and contacted with moulding rubber roll 1 or divide
From two states, prismatic pressure roller 2 includes roll body 21 and is uniformly arranged on the wedge angle 22 on roll surface along roll body 21 circumference.
Further, prismatic pressure roller 2 and fixing rubber roll 3 are arranged on stationary roller shaft 4, and prismatic pressure roller 2 and fixing glue
Roller 3 is respectively provided with two, and prismatic pressure roller 2 is located at two side positions, and fixing rubber roll 3 is centrally located.Fixing rubber roll 3 and moulding glue
It is to compress pole piece that roller 1 contacts, and it is moulding in order to carry out to negative electrode lug that prismatic pressure roller 2 is contacted with moulding rubber roll 1.
Further, stationary roller shaft 4 is fixed on pressing roller holder 6 by roller frames 5, and pressing roller holder 6 is included positioned at moulding
The cross bar 61 of rubber roll 1 upside and the column 62 being located at moulding rubber roll 1 side, the top phase of cross bar 61 and column 62 is fixed.
Further, elevating mechanism includes the lift controil valve 71 being arranged on pressing roller holder 6 and connects pressing roller holder 6
With the elevating lever 72 of roller frames 5, one end of elevating lever 72 is fixedly connected with roller frames 5, and the other end of elevating lever 72 passes perpendicularly through
Cross bar 61, and move up and down in the direction of control lower edge cross bar 61 restriction of lift controil valve 71, to drive prismatic pressure roller 2 and to consolidate
