Description
Technical field
The present invention relates to technical field of lithium batteries, and in particular to a kind of dress for lithium ion cell polar ear bending correction
Put.
Background technology
In lithium ion battery production process, the lug state of pole piece is directly connected to the welding situation of battery cap, and
The internal resistance size of battery, more concerns battery with two side terminals by the gross.
Because in process of production, lug is collided after cutting is molded by external force, and pole piece itself stress release, portion
Bending state is presented in split pole ear, and after being handled by up- coiler, bending state is more obvious, and part lug bending enters barrier film
It is interior, cause large quantities of core need it is artificial repair, the battery of reparation easily occurs that short-circuit and interior resistive is big to be waited extremely.
The content of the invention
To solve in actual production process due to the short circuit of battery caused by lug bending, internal resistance is big and top cover failure welding
The problem of, the present invention provides a kind of lithium ion cell polar ear bending apparatus for correcting, improves the quality of battery, reduces the work of personnel
Industry amount, more improve the security of battery system.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of lithium ion cell polar ear bends apparatus for correcting, including cantilever rotating shaft, be set in it is encapsulated in the cantilever rotating shaft
Disk roller and the L-type support being connected with end bearing before the cantilever rotating shaft, hold-down mechanism are provided with the L-type support, the compacting machine
Structure includes hold-down roller and correct roller and the pressure roller dual-gripper for being connected hold-down roller and correct roller being mutually engaged with film winded roller.
Further, the straight line can be passed through by straight line axis connection, the hold-down roller between the hold-down roller and correct roller
Axle drives correct roller synchronous axial system.
Further, it is provided with buffer gear between the L-type support and hold-down mechanism.
Preferably, the buffer gear uses and pushes spring structure.
Preferably, the correct roller uses nylon gear.
From above technical scheme, apparatus for correcting of the present invention carries out correction process to lug, and strip is formed on its surface
Groove so that the vertical anti-pressure ability enhancing of lug, after rolling step, the bending situation of lug significantly reduces pole piece.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is to use the lug surface effect figure after apparatus of the present invention.
In figure：1st, cantilever rotating shaft, 2, film winded roller, 3, L-type support, 4, hold-down mechanism, 41, hold-down roller, 42, correct roller,
43rd, pressure roller dual-gripper, 44, linear axis, 5, buffer gear, 6, pole piece, 7, lug.
Embodiment
A kind of preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the lithium ion cell polar ear bending apparatus for correcting includes cantilever rotating shaft 1, film winded roller 2, L-type branch
Frame 3, buffer gear 5 and hold-down mechanism 4.The cantilever rotating shaft 1 is a part for hoist engine, and film winded roller 2 is set in cantilever and turned
On axle 1, and it is connected with cantilever axis of rotation, L-type support 3 with end bearing before cantilever rotating shaft, the hold-down mechanism 4 passes through buffer
Structure 5 is connected with L-type support 3.
The buffer gear 5 increases the pressure of disk roller using spring using spring structure is pushed, so as to adjusting grooves
The depth.
The hold-down mechanism 4 includes hold-down roller 41, correct roller 42, linear axis 44 and pressure roller dual-gripper 43, wherein hold-down roller
It is connected with correct roller by linear axis with pressure roller dual-gripper, the upper end of the pressure roller dual-gripper is connected with buffer gear 5.Hold-down roller 41
Power is provided for correct roller, correct roller synchronous axial system can be driven by the linear axis, avoid lug caused by correct roller skidding from tearing
Split, correct roller 42 is preferably a kind of nylon gear, can form a plurality of parallel groove, reference picture 2 in pole piece.The present embodiment
In, hold-down roller 41 and correct roller 42 are located at the top of film winded roller 2, and wherein correct roller is mutually engaged with film winded roller, not damaged
In the case of lug, perfect groove can be formed.Right position can be adjusted at hold-down roller and correct roller, is easy to handle different in width
Pole piece.
In the course of work, when pole piece 6 is by between hold-down roller 41 and rubber covered roll 2, pole piece 6 drives hold-down roller 41 to rotate, this
When correct roller 42 rotated with hold-down roller 41 with synchronizing speed, lug 7 is by between correct roller 42 and rubber covered roll 2, due to buffer
The elastic force effect of structure 5, correct roller 42 form strip groove on the surface of lug 7, have the function that to strengthen support force, increase lug
Vertical anti-pressure ability.Strip groove starting point is 2mm apart from the edge of pole piece 6 after processing, and the present apparatus is arranged on tension of winder
After roller, before pole piece deviation correction device, the uniformity of lug position is ensure that, step is simple, efficiency high, and pole piece is rolled up after correction
Around processing, lug fraction defective substantially reduces, and avoids quality problem caused by artificial reparation bending lug after winding, ensure that electricity
The uniformity in pond, improve the yields of battery.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, it all should fall into the protection domain of claims of the present invention determination.
