Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
In this embodiment:
a technical method for compensating a flat cable comprises the following steps:
and detecting errors, namely detecting the high-low deviation condition of the flat cable on the spool by combining at least two sampling methods. The error detection includes the following three sampling methods: equidistant sampling method, reference comparison sampling method, and occupied sampling method. The weights of the three sampling methods in the error detection are all 1/3. The method of each sampling method is different, the principle of sampling is different, the emphasis is different, the reaction condition is different, the obtained result is different, but the condition of the wire arrangement at the two ends of the spool can be reflected, the three sampling methods are combined, the result deviation of a single sampling method is avoided, and the detection result is more accurate
And (5) carrying out overshoot treatment, and reversing the flat cable at a target reversing point by detecting and treating the overshoot. The detection of the overshoot processing adopts a high-speed bus, and the high-speed bus is specifically an industrial EtherCAT bus, so that the high-speed bus can detect the actual overshoot of the bus cable at high speed or low speed. The overshoot is the distance between the actually generated reversing point and the reversing point required by the target, the processing method of the overshoot processing is to carry out first-order filtering according to the detected overshoot, and confirm the position of the control reversing point, so that the reversing process of the flat cable can occur at the control reversing point, and finally reversing is completed at the reversing point required by the target as far as possible, namely the setting of the control reversing point can opposite-impact the overshoot. Therefore, the reversing can be performed at the target reversing point as much as possible, the production error caused by the wire arrangement reversing is reduced, and the problems of wire laying, wire pressing and wire clamping caused by redundant wire arrangement are avoided. The first-order filtering formula is Y (n) =alpha X (n) + (1-alpha) Y (n-1), wherein alpha is a filtering coefficient; x (n) is the impulse data of the current time; y (n-1) =the up-filter output value; y (n) =the current filter output value; alpha is a number between 0 and 1. The first-order filtering has good inhibition effect on interference caused by the winding displacement commutation period.
The reversing treatment, namely reducing the influence of too tight wire arrangement caused by the slow running speed of the wire arrangement before reversing by adjusting the running speed of the wire arrangement; the adjusting method of the reversing treatment is to additionally speed up the operation speed of the flat cable in a set time after the flat cable is reversed. In this embodiment, specifically, the method includes: the operation speed of the flat cable needs to be slowed down before the flat cable is reversed, at the moment, the flat cable is too compact, if the absolute value of the deceleration acceleration before the reversal is accelerated after the reversal is finished, the situation that the flat cable is too high due to the compact flat cable can occur, so the operation speed of the flat cable can be far higher than the acceleration of the absolute value of the deceleration acceleration before the reversal due to the treatment of the reversal after the reversal is finished, the flat cable is sparse in a period of time after the reversal is finished, the flat cable is compact due to the opposite-flow reversal, and the flat cable height is moderate.
And R angle compensation, and obtaining a winding displacement method of the R angle of the spool through an algorithm. The algorithm of R angle compensation is a roll diameter calculation algorithm. R angle compensation calculates the winding displacement area of the R angle of the spool according to the lifting height of the winding displacement. In this embodiment, as the number of layers of the flat cable is higher, the width of the flat cable is wider due to the existence of the R angle, and the actual elevation of the flat cable is calculated by using the roll diameter calculation algorithm, so that the position where the flat cable of the R angle is to be reached can be predicted, the flat cable method at the R angle is processed in advance, the flat cable precision is improved, and the problems that the flat cable at the R angle at two ends of the spool is possibly too high or too low and the flat cable is wire-released and wire-clamped due to the confusion of the flat cable at the R angle are solved.
And pre-judging and compensating, wherein after the flat cable is finished in a fixed layer number, one-time compensation is given according to the existing deviation of the flat cable. The number of the fixed layers for prejudging and compensating is 15. The pre-determined compensating existing deviation is opposite side deviation or R angle error. In this embodiment, the first 15 layers do not perform any processing, and perform wire arrangement according to the opposite sides of the spool and the existing data, after the wire arrangement of the 15 layers is completed, the two ends or the high or low of the spool can be directly observed, at this time, the problem of high or low of the wire arrangement is largely compensated once, a part of the wire arrangement problem is solved, the wire arrangement is prevented from being in a state of high or low for a long time, and thus, the pre-judgment compensation is performed, and the problem accumulation for a long time in the later period of placement causes the problem of extremely worsening the wire arrangement to be difficult to solve.
And (3) dislocation compensation, wherein the two ends of the spool are comprehensively detected or the compensation position is not fixed by changing the reversing position of the flat cable. In this embodiment, the winding displacement is not fixed in a position, so that the conditions at two ends of the spool can be detected as much as possible, meanwhile, the compensating position can be changed due to the unstable reversing position, the dead circulation condition of continuously compensating the same position can not occur, the whole compensating process is more active, the compensation can be more comprehensive, and the winding displacement is smoother.
In this embodiment, the compensation data of the above modules can be recorded, and can be applied to the next production, so that the repeated calculation of the compensation process is avoided, and the production efficiency is greatly improved.
The present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide a portable electronic device capable of performing various changes and modifications without departing from the scope of the technical spirit of the present invention. The technical scope of the present invention is not limited to the description, but must be determined according to the scope of claims.
