A method for calculating the using amount of an adhesive tape in wiring harness processing comprises the following steps:
step s 1: determining the outer diameter D and the length L of the area of the wire harness to be wound with the adhesive tape0And the width H of the tape.
The thickness of the tape need not be determined at this step, since the thickness is not on the order of magnitude and the width is not on the order of magnitude, the thickness has a negligible effect on the amount of tape used.
Step s 2: respectively winding n from a starting point A and an end point B of the wire harness area by adopting a point winding method1A ring and n2Looping to obtain the length X of the adhesive tape used at the starting point A1And end point B uses length X2，X1＝πDn1，X1＝πDn2Obtaining the length L of the middle area C as L0-2H, area S of the intermediate region C0＝πDL。
In this step, n1＝ n 22 or 3.
Step s 3: when the intermediate area C adopts the point winding method and the flower winding method, the adhesive tape does not completely cover the surface of the wire harness, and the interval P between adjacent winding nodes and the number n of winding turns on each node are determined3And calculating the number n of nodes and the theoretical use length X of the adhesive tape in the middle area C0Wherein n is an integer; when the middle area C adopts the overlapping winding method, the adhesive tape completely covers the surface of the wire harness, and the single-side overlapping winding proportion is determined to be eta0Calculating the actual winding area S' of the middle area C, and calculating the theoretical use length X of the adhesive tape of the middle area C0；
In this step, the length of the non-wound tape region (blank region) between adjacent wound nodes is P0。
When the middle area C adopts a point winding method, n is L/P-1, and P is P0+H，X0＝πDn3n；
When the intermediate area C adopts the flower winding method, the adhesive tape is spirally wound along the wire harness, as shown in fig. 3, the adhesive tape can be regarded as forming a plurality of repeated waveforms along the length direction of the wire harness, the number of the waveforms is equal to the number of nodes n, the actual interval P 'between adjacent winding nodes is calculated, the included angle between the starting point of the waveform and the length direction of the wire harness is alpha, the length X' of the adhesive tape of each waveform and the theoretical use length X of the adhesive tape of the intermediate area C are alpha0。
n-L/P (rounded), P' -L/n,
X0＝nX′；
it should be noted that L/P is not always divided evenly, i.e. the actual value of n is not an integer, and n should be adjusted to an integer in this case, which can be achieved by the following three methods: 1) upward rounding: the ratio of the total length of the branches to the center distance of the nodes, 2) the adjustment of the adjustment is carried out, and the ratio is 1 less; 3) under the condition that the spacing management and control requirements are not high, the spacing is increased or decreased to meet the requirement of equal division.
When the intermediate region C adopts the overlapping method, the actual overlapping area proportion eta is equal to2η0. The description is as follows: when the adhesive tape is overlapped and wound, a certain node is wound with a plurality of circles of adhesive tapes, specifically, the lower end of the lower adhesive tape of the node is covered by the upper adhesive tape, and the coverage proportion is eta0That is, the single-side overlapping winding ratio, the upper layer adhesive tape continues to wind the wire harness and covers the upper end of the lower layer adhesive tape, and the covering ratio is equal to eta0Therefore, the actual overlapping area ratio of the lower tape is 2 η0Calculating the actual winding area S' ═ S of the middle area C0×(1+2η0) Theoretical total length of tape used in the middle area C
