The pole piece coiling method utilizing the aforesaid pole piece coiling equipment of a kind of pole piece of embodiment, comprises the steps:
Set up level electronic cam curve, the servomotor 41 of described level electronic cam pack controls according to the distance that moves horizontally of described level electronic cam curve to described horizontal pole piece roller 49;
Wherein, in described level electronic cam curve:
Wherein, L
actrepresent that the real-time pole piece in i-th curve point of described level electronic cam curve corresponding moment unreels length, Δ L represents from i-th curve point corresponding moment to the step-length that the pole piece in the i-th+1 curve point corresponding moment unreels, F represents the vertical range of horizontal pole piece roller to pole piece pan feeding assembly, Δ l represents the distance of moving in the horizontal direction from horizontal pole piece roller 49 described in+1 curve point corresponding moment in i-th curve point corresponding moment to the i-th, because the time interval between curve point is also known, therefore Δ l has reacted the horizontal movement speed of horizontal pole piece roller 49 equally, same Δ L has also reacted the speed that pole piece unreels.In the process setting up this level electronic cam curve, above-mentioned relation will be stored.
Therefore, according to this level electronic cam curve, servomotor 41 can compensate the speed that pole piece unreels by level of control pole piece roller 49 preferably, thus the speed of pole piece is remained in certain fluctuation range.
Preferably, carry out in the process of velocity compensation at described servomotor 41 to horizontal pole piece roller 49, unreel length due to winding motor according to the actual pole piece detected of current time and horizontal pole piece roller 49 moves horizontally distance, the position of described horizontal pole piece roller is compensated.Concrete compensation can be:
such as, in actual winding process, when detect horizontal pole piece roller 49 current to move horizontally distance, delta l' not identical with the Δ l of corresponding level electronic cam curve, then can compensate the distance that moves horizontally of horizontal pole piece roller 49; In like manner, when detecting that the current of pole piece unreels length and the L in corresponding level electronic cam curve
actnot identical, then can compensate the distance that moves horizontally of horizontal pole piece roller 49, if compare L
actthe horizontal pole piece roller 49 of large then increase move horizontally distance, if compare L
actlittle, the horizontal pole piece roller 49 of reduction move horizontally distance.
In order to reduce the fluctuation of pole piece linear velocity further, volume pin servomotor can be utilized to control described square volume pin 56 according to volume pin electronic cam curve; Wherein, described volume pin electronic cam curve is obtained by following algorithm:
If L
act-L'
act> Δ L, then judge
whether be greater than 0 and be less than V
max;
If 0 < v < V
maxthen judge that i-th curve point of described volume pin electronic cam curve is normal, and the next one of described volume pin electronic cam curve, i.e. the i-th+1 curve point are calculated, until complete the foundation of whole volume pin electronic cam curve according to the algorithm of volume pin electric cam:
If i≤N, then
If i > is N, then
Wherein, y (i) and y (i-1) represent the angle of described square volume pin when i-th curve of described volume pin electronic cam curve respectively and the i-th-1 curve point time angle, the entirety in bracket represents the sequence number of curve point, D
actand D
0represent that described square volume pin is at the real-time winding angle in i-th curve of described volume pin electronic cam curve corresponding moment and square volume pin initial angle respectively, x (i) and x (i-1) represents the length of pole piece in described volume pin electronic cam curve i-th curve point and the length of the i-th-1 curve point, L respectively
0for when after described square volume pin is threaded a needle and described square volume pin is in level time pole piece initial length, N is sliding average filtering factor, D'
actrepresent the real-time winding angle in the moment that i-th curve point of described volume pin electronic cam curve is corresponding, L'
actrepresent that the real-time pole piece in the i-th-1 curve point of described volume pin electronic cam curve corresponding moment unreels length, V
maxpole piece amplitude limit speed.
It should be noted that, the curve point of level electronic cam curve and the curve point of volume pin electronic cam curve are one to one, and the number comprising curve point is identical.
After establishing volume pin electronic cam curve, volume pin servomotor can control volume pin according to volume pin electronic cam curve, and then carries out control and compensation to the linear velocity of pole piece.When the control inadequate resource of the controller of described volume pin servomotor, (computational resource of such as servomotor is occupied too much by other unit, cannot complete in time volume pin control algorithm), can by z (i) zero setting corresponding for some curve point of described volume pin electronic cam curve; Then according to following algorithm, volume pin and pole piece are controlled:
If during z (i)=0: y (i)=k*x (i)+s;
When z (i)=1: y (i)=a*x (i)
3+ b*x (i)
2+ cx (i)+d;
Wherein, k and s carries out coefficient of first order that first derivation obtains and zero degree coefficient to described volume pin electronic cam curve the i-th-1 curve point, and a, b, c and d carry out the i-th-1 curve point three ordered coefficients, quadratic coefficients, coefficient of first order and the zero degree coefficient that three rank differentiates obtain to described volume pin electronic cam curve.Like this, when the inadequate resource of controller, the first power interpolation that operand is less can be used, when the resource of controller is sufficient, the cube interpolation that operand is larger can be used.
As Fig. 3 to Fig. 9 is known; when the width (referring to the length of EB) of square volume pin 56 is larger (and width is larger; its EB length usually can be more greatly than the length of CB, AB, DE and EF); therefore; the change of the winding radius of square volume pin is also larger, thus causes the fluctuation of pole piece linear velocity also strong with regard to Shaoxing opera.As a rule, to the interval more intensive (namely Δ L is less) of the sampled point of the volume pin electronic cam curve of volume pin servomotor, the volume pin electronic cam curve obtained is also more close with actual curve.But, when causing violent pole piece linear velocity fluctuation when the width of square volume pin 56 is larger, because the restriction of motor actual performance (such as, there be limited evidence currently of motor in 3ms from the direct raising speed of 100rpm to 12000rpm), even if increase Δ L further, the acceleration of motor also cannot catch up with the pole piece linear velocity of big ups and downs, cannot obtain close to actual operation curve.
Therefore, when described square volume pin 56 width is less, larger described Δ L can be adopted, can obtain more close to the volume pin electronic cam curve close to actual operation curve like this; And when the width of volume pin 56 square described in motor is larger, then can adopt less Δ L, and then the interpolation of above-mentioned algorithm is utilized according to volume pin electronic cam curve, allow servomotor make the operation of maximum possible according to the performance of oneself.Such as, when square volume pin width is less than 60mm be, Δ L=0.4mm, when square volume pin width is more than or equal to 60mm, Δ L=0.75mm.
And due to different size battery core required for the width of square volume pin 56 different, if often change once square volume pin 56, namely will input corresponding data can be cumbersome, therefore, the width of square volume pin 56 can be upgraded by the mode of self study, can calculate described square volume pin width by following algorithm:
Wherein, H is the width of described square volume pin 56, L
0for when after described square volume pin 56 is threaded a needle and described square volume pin 56 is in level time pole piece initial length (state as shown in Figure 3, but pole piece has put on square volume pin 56), L
act1for the moment pole piece after described square volume pin rotates 180 ° from described level unreels length, such as, rotate counterclockwise.
Preferably first calculate and set up described level electronic cam curve, and then calculate described volume pin electronic cam curve, like this because the coupling of horizontal pole piece roller 49 is on pole piece, the volume pin electronic cam curve that therefore obtains more close to actual curve (with first set up roll up pin electronic cam curve after set up compared with level electronic cam curve).
