Description
Technical field
The utility model relates to the tension force control field of coiler device, refers more particularly to the follow-up tension force control that needs the electrochemical energy storing device coiling operation of fluid injection such as battery, ultracapacitor.
Background technology
Electrochemical energy storing device such as battery and ultracapacitor have obtained using widely in the world, and electric core is the core of electrochemical energy storing device.Electrode material has directly determined the performance of electrochemical energy storing device, and the structure of electric core and processing technology also have very big influence to the performance of electrochemical energy storing device.Be example with the takeup type electrochemical energy storing device, the electric core winding structure especially elasticity to the important influence of follow-up fluid injection operation.
At present, electric core winding technology mostly is permanent tension force control greatly, and the electric core uniformity that coiling comes out is better, but needs to accept or reject to some extent aspect particular product performance parameters and processing cost.The electric core winding tension, then electrolyte is difficult to be distributed to electric in-core portion fluid injection the time, problem such as cause follow-up fluid injection process efficiency to reduce, the device power density reduces; Electric core winding is loose excessively, then can reduce the energy density of device and cause degradation problem under the device reliability that causes owing to structural instability.At this problem, the someone has proposed the method for winding that tension force successively decreases:
A kind of method for winding that becomes tension force is disclosed as Chinese patent 200910106521.4 " a kind of cylindrical secondary battery bare electric core winding variable tension control method ".This method is set the coiling initial tension, and behind two circles of reeling, passing ratio valve regulation and control cylinder output pressure and then adjusting winding tension successively decrease, and the core strueture of making fluffs from inside to outside gradually, but this method still has following shortcoming:
1, proportioning valve and cylinder carry out stability and the very difficult assurance of precision of tension adjustment.
At first, the unsteadiness of bleed pressure and temperature is to the influence of system;
Secondly, proportioning valve is by the adjustments of gas flow and then regulate the cylinder output pressure, and the moment that each adjusting essence all is air-flow increases or reduces, and sudden changes in pressure can form damped oscillation in cylinder, cause cylinder output pressure instability;
At last, proportioning valve and cylinder tension control system are owing to be elastic system, and its control precision and response speed can't reach actual instructions for use, especially under the situation that production efficiency is accelerated, the electric core of reeling only needs to think accurately to control under the situation about ten seconds, and is very difficult.
2, since electric core fluff gradually from inside to outside, poor, the structural instability of electric core out of roundness, core strueture caves in easily and causes short circuit in the follow-up course of processing, and is also influential to follow-up welding sequence etc.
3, alternation formula structure tight inside but loose outside science not: the collector of general electrode of electrochemical device sheet be no infiltrative Copper Foil or aluminium foil, and is to follow-up fluid injection operation, very slow in the direction electrolyte infiltration perpendicular to electric core coil diameter.Therefore the difficult point of the difficult point electricity core that absorbs of fluid injection operation electrolyte is not at electric core skin, but internal layer in the electric core, and tight inside but loose outside electric in-core portion is not good scheme.In addition, the core strueture tight inside but loose outside that progressively successively decreases can cause the reduction of energy density.
The utility model content
The purpose of this utility model is to propose a kind of practicable solution at the tension force control problem that electrochemical energy storing device electric core winding process exists, and a kind of programmable electric core winding system and method for tension force that has improved the production efficiency of follow-up fluid injection operation on the basis of not losing its performance substantially greatly is provided.
The utility model adopts following technical scheme for achieving the above object:
The programmable electric core winding of a kind of tension force system is characterized in that: this system comprises the servomotor unwinding device, unreels linear velocity detection device, deviation correcting device, servomotor tenslator, servomotor coiler device, electric core winding linear velocity detection device and PLC controller; Wherein
Described servomotor unwinding device and servomotor coiler device are used for discharging and the electric core volume of reeling, and winding tension is provided;
Describedly unreel the linear velocity that linear velocity detection device and electric core winding linear velocity detection device are reeled for detection of electric core volume, and feed back to described PLC controller;
Described deviation correcting device unreels the side of electrode for tracking and adjusts in real time according to error;
Described servomotor tenslator is used for the tension force that the electric core volume of control is reeled;
Described PLC controller is used for control servomotor unwinding device and the servomotor coiler device rotates, and receives the FEEDBACK CONTROL winding speed and the tension force that unreel linear velocity detection device, electric core winding linear velocity detection device, servomotor tenslator.
The programmable electric core winding method of a kind of tension force comprises the steps:
(1) in the PLC controller, sets initial winding tension and winding tension function;
When (2) reeling beginning, the counter-rotating of servomotor unwinding device reaches initial tension, start servomotor unwinding device and servomotor coiler device, it is synchronous to carry out speed according to the detection feedback result that unreels linear velocity detection device and electric core winding linear velocity detection device, the PLC controller receives the data of servomotor tenslator output and contrasts in real time with the tension variation function of setting in the winding process, controls that the servomotor unwinding device accelerates or the tension force that keeps the servomotor tenslator to detect of slowing down is consistent with the tension variation function of setting again;
(3) in whole winding process, deviation correcting device is followed the trail of and is unreeled the side of electrode and adjust the end face regularity of electric core after guaranteeing to reel according to error in real time.
It is further characterized in that: the winding tension function in the described step (1) is, T=A+B*sin[(Ct)
1/2], wherein T is tension force, and t is the coiling time, and A, B, C are non-zero constant.
Preferably: described tension force control range is 0.05-0.4 MPa.
The utility model system and method is realized the elasticity of core strueture is designed by the accurate control to winding tension.Described tension variation program is decided according to core strueture, at different products and the different size of like products, can effectively carry out the core strueture design.Response speed is fast because servomotor has, the control precision advantages of higher, can realize tension adjustment and output in the millisecond rank, make the staggered core strueture that changes of coiling degree of tightness, thereby can under the prerequisite that needn't sacrifice properties of product, realize the optimization of manufacture craft, promote the production efficiency of follow-up fluid injection operation.
Because the tension variation program of setting not is permanent tension force, the utility model uses servomotor to carry out tension adjustment, and servomotor directly acts on spool, needn't pass through intermediate gearing, so its response time is the time of implementation, can reach 0.5ms, this speed enough satisfies the demands.In addition, because servomotor belongs to positive drive, so the output tension stability has been avoided because the electric core quality problems that tension fluctuation brings.
