Description
Technical field
The utility model relates to a kind of tenslator, refers in particular in a kind of process manufacturing lithium cell and carries out the accurate tenslator controlled to the tension force of the banded pole piece of battery or banded barrier film.
Background technology
Lithium battery pole slice and barrier film are a kind of thinner, softer objects, in the coating of battery manufacture, itemize, the technique such as winding and lamination, there is uncoiling and the rewinding mechanism of pole piece coiled strip and barrier film coiled strip in many places, in uncoiling and rewinding process, it is very important that tension force controls.Common are swing arm both at home and abroad adds air-cylinder type tenslator at present, roller tenslator, tension gauge adds clutch type tenslator totally three classes, but existing various tenslator all exists tension fluctuation scope greatly, the defects such as tension response poor sensitivity.Swing arm type because its be quick on the draw be used for up-coiler unreel, roll up forward pull control, but existing mechanism because its cylinder action in fulcrum.Behind swing arm drift angle, as shown in the structure diagram in Fig. 5 and Fig. 6: this tenslator has following shortcoming: the first, the arm of force changes, L2a ≠ L2b, stress value is different from output (control).The second, organize roller instantaneous linear velocity different, form own tension variation.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fast response time and more stable tenslator, thus the fluctuation that reduction is led the way, to reduce the deflection of battery core.
Technical matters of the present utility model is achieved through the following technical solutions: provide a kind of tenslator for the manufacture of lithium cell, it comprises a swing arm, also comprise and be arranged in this swing arm and make the jockey pulley assembly of strip-cell pole piece or banded barrier film tensioning, moment of torsion is provided to arrive the servomotor of this jockey pulley assembly, and identifying the position detecting mechanism of this swing arm state and control Tensity size, this position detecting mechanism is interconnected by a coupler and this servomotor.
Preferably, this position detecting mechanism comprise rotating shaft cover, tension axis, be fixed on the potentiometer that this rotating shaft puts, the coupler that the other end of this tension axis and this potentiometric input shaft are coupled together.
Preferably, this servomotor provides moment of torsion that this swing arm is moved to the left or to the right, and this tension axis drives this potentiometric input shaft to rotate by this coupler, and angle position signal is fed back to the control system adjusting the speed unreeled by this potentiometer.
Preferably, this servomotor is supported by a motor supporting device.
Relative to prior art, the utility model is driven the mode of jockey pulley component movement by servomotor owing to structurally changing, servomotor provide constant moment of torsion to make jockey pulley assembly when different motion position stressed be consistent, the tension force passing to lithium battery pole slice or barrier film when therefore different angles put by jockey pulley assembly is stable.In addition, the utility model has the high advantage of tension force maintenance swing arm mode response sensitivity on structural principle.Structurally, cylinder is changed to servomotor induced way, well solve the defect that the tension force that causes jockey pulley assembly to pass to lithium battery pole slice or barrier film when diverse location because cylinder thrust varies in size differs, improve the stability of machine.

Detailed description of the invention
The utility model is a kind of tenslator for the manufacture of lithium cell, and its tension force control object is battery pole piece or battery diaphragm.When practical application, this tenslator can be connected with uncoiling mechanism, rewinding mechanism and electric core winding mechanism etc., realizes the tension force demand for control of the techniques such as winding, rewinding.
As shown in Figures 1 to 4, a swing arm 100 should be comprised for the manufacture of the tenslator of lithium cell, to be arranged in this swing arm 100 and to make the jockey pulley assembly 200 of strip-cell pole piece or banded barrier film tensioning, the servomotor 301 that moment of torsion arrives this jockey pulley assembly 200 is provided, and identifies the position detecting mechanism 400 of this swing arm 100 state and control Tensity size.In the present embodiment, by control Tensity size is strip-cell pole piece or banded barrier film.
This servomotor 301 is supported by a motor supporting device 300.The response sensitivity of this servomotor 301 is better than the response sensitivity of cylinder.This motor supporting device 300 is fixed in machine base plate (not shown).The moment of torsion that this servomotor 301 is supplied to this jockey pulley assembly 200 is constant, and this jockey pulley assembly 200 arm of force when swinging different angles does not change.This servomotor 301 by setting size of current control torque, thus controls the size of winding tension.
As shown in Figures 2 and 3, the position of the relative Fig. 1 of this jockey pulley assembly 200 is promoted to be moved to the left by this servomotor 301.This jockey pulley assembly 200 is along with this swing arm 100 side-to-side movement.
As shown in Figure 4, this position detecting mechanism 400 comprises rotating shaft cover 401, tension axis 402, the potentiometer 403 be fixed on this rotating shaft cover 401, the coupler 404 that coupled together by the input shaft of the other end of this tension axis 402 and this potentiometer 403.This position detecting mechanism 400 does not participate in the transmission of the tension force that this servomotor 301 provides, and a passive detection Motor torque makes swing arm 100 pendulum angle information feed back to unreeling motor, adjusts the speed unreeled.
This rotating shaft cover 401 is fixed on machine base plate.
Under open state, this swing arm 100 initial position is vertical direction, this servomotor 301 provides moment of torsion that this swing arm 100 is moved to the left or to the right, this tension axis 402 drives the input shaft of potentiometer 403 to rotate by this coupler 404, angle position signal is fed back to control system by this potentiometer 403, to adjust the speed unreeled.
The arm of force be subject to due to jockey pulley assembly is constant when jockey pulley assembly swings different angles, and the tension force making jockey pulley assembly pass to lithium battery pole slice or barrier film when diverse location is stable, thus improves tension force control accuracy.Because the speed of response of servomotor is higher than cylinder in the past, tension fluctuation is little, and pole piece is roll release not, has tension force and controls stable, winding precision advantages of higher.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
