Fig. 1 shows the specific embodiment that this battery roll core of the application rubs quadratic method, the main feature of this method
It is: when carrying out rubbing flat operation to battery roll core 1, by the disk at flush end to be rubbed (i.e. the white edge end) and a turntable 2 of battery roll core
Abutting contact arrangement, and guarantee the central axes L1 of battery roll core 1 and the central axes L2 of turntable 2 makes an angle alpha arrangement, 90 ° of 0 < α <,
That is α is acute angle.Make turntable 2 and battery roll core 1 rotating around own central axis line rotate, i.e., turntable 2 around turntable central axes L2 rotation,
Central axes L1 rotation of the battery roll core 1 around battery roll core.
It can be appreciated that because the white edge end (flush end i.e. to be rubbed) of battery roll core 1 and the disk abutting contact of turntable 2 are arranged, therefore
And at this bending deformation can occur under power effect for the white edge of 1 end of battery roll core, and turntable 2 supports aforementioned white edge application
By extruding force in Fig. 1 straight up, the angle between the central axes L1 of battery roll core 1 and the central axes L2 of turntable 2 is that non-zero is non-
90 ° of acute angle, therefore radially inward bending deformation can only occur to the center of core for the white edge of battery roll core 1, without outside
It routs up, improves the shaping effect to core white edge.When battery roll core 1 and turntable 2 are rotated rotating around own central axis line, battery
1 white edge end of core and the contact site of turntable 2 constantly change, and make the equal energy of white edge at each position on battery roll core white edge end
Turntable is enough touched, and in the two under extruding force effect, makes white edge everywhere that radially inward bending deformation occur.
At the same time, battery roll core 1 and 2 relative motion of turntable and generate lasting kinetic force of friction, which acts on electricity
On the white edge of pond core 1, white edge is made to be smoothed (soft (rubbing) is flat) by lasting polishing.
It is not difficult to find out that rubbing in flat operation process above-mentioned, the white edge of 1 end of battery roll core produces radial bending and becomes
Shape, so that the white edge end of battery roll core 1 integrally produces deformation of collapsing axially inwards, the length of battery roll core 1 shortens.
If remaining that turntable 2 and the relative position of battery roll core 1 immobilize during entirely rubbing flat, then end white edge
Size of collapsing at the end of rubbing flat initial stage and rubbing flat is constant always, so that it is poor to rub flat effect.In this regard, in order to further
Flat effect is rubbed in promotion, during turntable 2 and battery roll core 1 are rotated rotating around own axes, is preferably also applied to battery roll core 1
Add the axial thrust towards turntable 2, i.e., axial thrust applied to battery roll core 1, and the axial thrust is towards turntable.
It is above-mentioned rub flat during, under the action of above-mentioned axial thrust, battery roll core 1 slowly moves closer to turntable 2,
It rubs flat to gradually inwardly squeeze the white edge of core end, makes to rub flush end more closely knit.
If above-mentioned angle α is too small, white edge is easy to rout up outward, so that core end is scattered outward, causes core suitable
Benefit is transferred in battery case；If above-mentioned angle α is excessive, the bending angle that will lead to white edge is too small, and core end is rubbed flat not flat enough
It is whole closely knit.Therefore α cannot be excessive, and it can not be too small, it is preferably kept within the scope of 5 °~30 °.
From the foregoing, it will be observed that α is too small, the white edge of core end is easy to rout up outward；α is excessive, and it is poor to will lead to grinding effect.
In this regard, we can keep the angle of α larger, to guarantee that the white edge of core end especially makes outside core end at polishing initial stage
The white edge for enclosing part bends inwards；And in the polishing later period, keep the angle of α smaller, to guarantee the planarization of abrasive end and close
Reality promotes polishing quality.In other words, in the grinding process, continue with the polishing time, be gradually reduced the angle of α.
The contact site of above-mentioned battery roll core 1 and turntable 2 is in 2 non-central positions of turntable, can so promote battery winding
The speed that core 1 and turntable 2 relatively move, and then promote grinding efficiency.In addition, shown in referring to Fig.1, during rubbing flat operation,
In the overlook direction of turntable 2 (namely in the downward axis apparent direction of turntable), the direction of rotation of turntable 2 and battery roll core 1 is not
Together, turntable 2 rotates clockwise, and battery roll core 1 rotates counterclockwise, and the purpose being designed in this way lies also in promotion battery roll core
1 speed relatively moved with turntable 2, and then promote grinding efficiency.
For convenience of the above-mentioned implementation for rubbing quadratic method, the present embodiment also proposed a kind of battery winding of specially for carrying out above method
Core rubs leveling device, referring again to shown in Fig. 1, the device mainly includes: turntable 2, turntable rotation driving equipment 3, core folder 4, volume
Core rotation driving equipment 5, core axis move driving equipment 6 and angle adjustment equipment.
Turntable 2 is horizontally disposed in Fig. 1, and central axes are vertical straight line.Metal nickel plating polishing structure may be selected in turntable 1,
Also the other structures such as polyfluortetraethylene plate be can choose.
Turntable rotation driving equipment 3 is connected with turntable 2, to drive turntable 2 to rotate around the central axes of the turntable itself.
Core folder 4 is commonly configured to the knot being made of multiple clamping jaws for the battery roll core 1 that is fixedly clamped, core folder 4
Structure.When core folder 4 is fixedly clamped after rubbing flat battery roll core 1, the central axes of battery roll core 1 and the central axes of turntable 2 are in
Angle α arrangement, and 90 ° of 0 < α <.
Core rotation driving equipment 5 is connected with core folder 4, to drive 4 rotation of core folder, then by 4 dragging battery of core folder
Core 1 is rotated around the central axes of the battery roll core 1 itself.
Core axis moves driving equipment 6 and is connected with core rotation driving equipment 5, to drive 5 straight line of core rotation driving equipment
It is mobile, and then again by core rotation driving equipment 5 (and the core adjacent with core rotation driving equipment is pressed from both sides) dragging battery winding
Axial movement of the core 1 along battery roll core.The structure for realizing 1 white edge end of battery roll core and turntable 2 abutting contact and to
Battery roll core 1 applies the axial thrust towards turntable 2.
Angle adjustment equipment (not shown) moves driving equipment 6 with core axis and is connected, and is used to that core axis to be driven to move
The overturning movement of driving equipment 6, and then change the angle value of above-mentioned α.
In the present embodiment, above-mentioned core rotation driving equipment 5 is motor, the fixed company of motor shaft of core folder 4 and the motor
It connects.It is cylinder that above-mentioned core axis, which moves driving equipment 6, and aforementioned motor is fixedly connected with the cylinder axis of the cylinder.Angle adjustment equipment
For multi-spindle machining hand, such as five axis robots, six axis robot etc., the end of manipulator is fixedly connected with aforementioned cylinder.
Above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to allow people that can understand this Shen
Content please is simultaneously implemented accordingly, and the protection scope of the application can not be limited with this.It is all according to the application main technical schemes
The equivalent transformation or modification that Spirit Essence is done should all be covered within the scope of protection of this application.
