Therefore, the roll-to-roll machining process is adjusted based on the adjustment decision, thus solving technical problems of multiple material types, different characteristics, complex deformation influence factors and difficult roll-to-roll machining process control in existing roll-to-roll machining of the flexible material.
With reference to
In step 301, first vibration data of the first unwinding module, second vibration data of the second unwinding module, third vibration data of the pressing module, fourth vibration data of the winding module, and rotating speed data and winding tension data of the winding module are acquired.
In an example, the first vibration data of the first unwinding module may be FJ={f1, f2, . . . , fn}, the second vibration data of the second unwinding module may be DX={d1, d2, . . . , dn}, the third vibration data of the pressing module may be YZ={y1, y2, . . . , yn}, the vibration data of the winding module may be SJ={s1, s2, . . . , sn}, the rotating speed data of the winding module may be V={v1, v2, . . . , vn}, and the winding tension data of the winding module may be F={f1, f2, . . . , fn}, wherein a subscript 1-n represents different moments. Meanwhile, the vibration data of the modules, and the rotating speed data and the winding tension data of the winding module may be represented as (FJi, DXi, YZi, SJi, Vi, Fi), wherein i represents a moment.
In step 302, calculation is performed to obtain a plurality of health state level combinations according to preset health state levels, the first vibration data, the second vibration data, the third vibration data and the fourth vibration data.
In the embodiment of the present invention, step 302 may comprise the following sub-steps of:
clustering the first vibration data according to the preset health state levels to obtain a plurality of first vibration data sets;
clustering the second vibration data according to the preset health state levels to obtain a plurality of second vibration data sets;
clustering the third vibration data according to the preset health state levels to obtain a plurality of third vibration data sets;

combining the first vibration data sets, the second vibration data sets, the third vibration data sets and the fourth vibration data sets according to the preset health state levels to obtain the plurality of health state level combinations.
In concrete implementation, the first vibration data FJ of the first unwinding module, the second vibration data DX of the second unwinding module, the third vibration data YZ of the pressing module and the fourth vibration data SJ of the winding module may be divided into four clusters by a fuzzy clustering algorithm according to the four health state levels of the modules, comprising:
the first vibration data set CFJ={CFJ1, CFJ2, CFJ3, CFJ4};
the second vibration data set CDX={CDX1, CDX2, CDX3, CDX4};
the third vibration data set CYZ={CYZ1, CYZ2, CYZ3, CYZ4};
the fourth vibration data set CSJ={CSJ1, CSJ2, CSJ3, CSJ4};
CFJi represents the first vibration data set of the first unwinding module under a Gi health state level, CDXi represents the second vibration data set of the second unwinding module under the Gi health state level, CYZi represents the third vibration data set of the pressing module under the Gi health state level, and CSJi represents the fourth vibration data set of the winding module under the Gi health state level, wherein i=1, 2, 3, 4.
The first unwinding module, the second unwinding module, the pressing module and the winding module respectively have four different health levels, so that the roller shaft module may have 4*4*4*4 (256 in total) health state level combinations Z={Z1, Z2, . . . , Z256} in the roll-to-roll machining process of the flexible material, and only one state Zi may appear at the same time, wherein i=1, 2, . . . , 256.
In step 303, a data intersection of the first vibration data set, the second vibration data set, the third vibration data set and the fourth vibration data set is retrieved under each health state level combination.
In step 304, a rotating speed data cluster and a winding tension data cluster corresponding to each health state level combination are acquired based on the data intersection, the rotating speed data and the winding tension data.
According to the four clusters of the first unwinding module, the second unwinding module, the pressing module and the winding module, an intersected data set of CFJi, CDXi, CYZi and CSJi under each health state level combination Zi may be retrieved to obtain 256 winding module rotating speed data clusters VG={VG1, VG2, . . . , VG256} and 256 winding tension data clusters FG={FG1, FG2, . . . , FG256} under different health state level combinations Zi.
In step 305, the corresponding winding module rotating speed interval and winding tension value interval of the health state level combination are generated according to the rotating speed data cluster and the winding tension data cluster.
The corresponding winding module rotating speed interval and winding tension value interval of each health state level combination may be generated based on the rotating speed data cluster and the winding tension data cluster.
In an example, step 305 may comprise:
calculating a rotating speed arithmetic mean value of the rotating speed data cluster and a tension arithmetic mean value of the tension data cluster;
calculating a standard rotating speed error value of the rotating speed data cluster and a standard tension error value of the tension data cluster;
calculating to obtain the winding module rotating speed interval by using the rotating speed arithmetic mean value and the standard rotating speed error value; and
calculating to obtain the winding tension value interval by using the tension arithmetic mean value and the standard tension error value.
In concrete implementation, arithmetic mean values MV={MV1, MV2, . . . MV256} and MF={MF1, MF2, . . . , MF256} of 256 winding module rotating speed data clusters and 256 winding tension data clusters are calculated by a mean formula. Standard error values SEV={SEV1, SEV2, . . . , SEV256} and SEF={SEF1, SEF2, . . . , SEF256} of the clusters are calculated by a standard error formula. Then, the winding module rotating speed intervals Vqi(i=1, 2, . . . , 256) and the winding tension value intervals Fqi(i=1, 2, . . . , 256) under different health state level combinations are calculated by the arithmetic mean values and the standard error values. Mathematical expressions of Vqi and Fqi are as follows:
wherein Za is a confidence coefficient, which may be calculated by a confidence level of 95%, and at the moment, a value of Za is 1.96.
In step 306, an adjustment decision is generated by using the plurality of health state level combinations, the winding module rotating speed interval and the winding tension value interval.
After the winding module rotating speed interval and the winding tension value interval of each health state level combination are acquired, the health state levels of the first unwinding module, the second unwinding module, the pressing module and the winding module may be used as conditional attributes, and the winding module rotating speed interval and the winding tension value interval may be used as control rules to establish the adjustment decision of a control solution of the roll-to-roll machining device for the flexible material. Moreover, an adjustment decision table is further generated.
Specifically, the adjustment decision table is shown in Table 1:
In step 307, when abnormal data is monitored in the roll-to-roll machining process of the flexible material, a target health state level of an abnormal module corresponding to the abnormal data is acquired, wherein the abnormal module is one or more of the first unwinding module, the second unwinding module, the pressing module and the winding module.
In step 308, a target winding module rotating speed interval and a target winding tension value interval of the abnormal module are determined according to the target health state level and the adjustment decision.
In step 309, a winding module rotating speed is adjusted according to the target winding module rotating speed interval, and a winding tension is adjusted according to the target winding tension value interval.
In concrete implementation, when one or more abnormal data in the first unwinding module, the second unwinding module, the pressing module and the winding module are monitored in the roll-to-roll machining process of the flexible material, the health state levels of the modules are evaluated at the moment. According to the established adjustment decision, the matching winding module rotating speed interval and winding tension value interval are selected, and the winding module rotating speed and the winding tension at the moment are adjusted to be within the intervals.
In the present invention, the first vibration data of the first unwinding module, the second vibration data of the second unwinding module, the third vibration data of the pressing module, the fourth vibration data of the winding module, and the rotating speed data and the winding tension data of the winding module are acquired; the calculation is performed to obtain the plurality of health state level combinations according to the preset health state levels, the first vibration data, the second vibration data, the third vibration data and the fourth vibration data; the winding module rotating speed interval and the winding tension value interval of each health state level combination are generated based on the rotating speed data and the winding tension data; and the adjustment decision is generated by using the health state levels, the winding module rotating speed interval and the winding tension value interval. Therefore, the roll-to-roll machining process is adjusted based on the adjustment decision, thus solving technical problems of multiple material types, different characteristics, complex deformation influence factors and difficult roll-to-roll machining process control in existing roll-to-roll machining of the flexible material.
