For more manual air spring devices, the cord fabric lamination relies on mechanical edge stops and manual deviation correction. The cord fabric cord is relatively soft, the edge stop effect is limited, and the manual deviation correction is inefficient and prone to uneven stretching of the cord fabric.

[0024] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, the orientation terms such as "upper, lower, top, bottom" generally refer to the directions shown in the drawings or to the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contours of the respective components themselves, but the above orientation terms are not used to limit the present invention.

[0026] In order to solve the problem of poor deviation correction effect of the cord fabric in the prior art, the present application provides a cord fabric deviation correction method and a deviation correction device.

[0027] Moreover, the deviation correction device in the present application performs deviation correction using the following cord fabric deviation correction method.

[0028] The cord fabric deviation correction method in the present application includes: setting cord fabric parameters and starting detection, where the cord fabric parameters include the set cord fabric angle α, the set cord fabric length L, and the set cord fabric width W; when the cord fabric is detected, start recording the length and perform deviation correction on the first side 10 and the second side 20 of the cord fabric, that is, when there is material under the deviation correction lens, the encoder starts to record the length. And when performing deviation correction on the second side 20, simultaneously measure the real-time cord fabric width and calculate the deviation correction position; when performing deviation correction on the first side 10 and the second side 20, first perform deviation correction on the first side 10, after a first preset length, perform deviation correction on the second side 20, and after passing through a second preset length A, perform deviation correction on the first side 10 of the new cord fabric again until the deviation correction of all the cord fabric is completed. Or rather, when the lens can no longer detect the cord fabric, stop the deviation correction.

[0029] When using the cord fabric deviation correction method in the present application, it is possible to solve the problem that the change in the width of the head and tail of the cord fabric causes a change in the deviation correction target position and it is impossible to perform deviation correction according to the set width. Through the cord fabric deviation correction method of this solution, automatic deviation correction during the cord fabric fitting process is achieved, and a good effect after fitting is obtained. Therefore, the cord fabric deviation correction method in the present application effectively solves the problem of poor deviation correction effect of the cord fabric in the prior art.

[0030] In the present application, after setting the cord fabric parameters, input the cord fabric parameters into the deviation correction device, and start to perform deviation correction on the cord fabric rubber material through the deviation correction device.

[0031] Specifically, after performing deviation correction on the second side 20 of the previous cord fabric, use the average value of the real-time cord fabric width as the set cord fabric width W for performing deviation correction on the subsequent cord fabric.

[0032] Specifically, the value range of the second preset length A is: 0 < A < L - W / tanα; or 5mm ≤ A ≤ 10mm.

[0033] Specifically, the cord fabric parameters further include the cord fabric type, and corresponding to different cord fabric types, the first preset length and / or the second preset length A are different.

[0034] As shown Figures 1 to 3 in the figure, the types of cord fabrics include the first type of cord fabric, the second type of cord fabric, and the third type of cord fabric. The sum of the lengths of the first side 10 and the second side 20 of the cord fabric corresponding to the first type of cord fabric is greater than the length of the cord fabric; the sum of the lengths of the first side 10 and the second side 20 of the cord fabric corresponding to the second type of cord fabric is equal to the length of the cord fabric; the sum of the lengths of the first side 10 and the second side 20 of the cord fabric corresponding to the third type of cord fabric is less than the length of the cord fabric.

[0035] Specifically, the first preset length corresponding to the first type of cord fabric is L - A, and the deviation of the first side 10 of the cord fabric corresponding to the first type of cord fabric is corrected within the first preset length all the time.

[0036] Specifically, the first preset length corresponding to the second type of cord fabric includes a deviation correction length and a non - deviation correction length. The non - deviation correction length is 2B, and the deviation correction length is L - B, where B is the maximum deviation value between the set cord fabric length L and W1 / tanα, and W1 is the actual width of the cord fabric. The deviation of the first side 10 of the cord fabric is corrected within the deviation correction length, and the deviation correction of the cord fabric is stopped within the non - deviation correction length. Moreover, the deviation of the first side 10 is corrected first, and the deviation correction of the first side 10 is stopped after the deviation correction of the first side 10 is completed.

[0037] Specifically, the first preset length corresponding to the third type of cord fabric includes a deviation correction length and a non - deviation correction length. The non - deviation correction length is 2B1 + C + 2D, and the deviation correction length is L - D, where B1 is the maximum deviation value between W / tanα and W1 / tanα, W1 is the actual width of the cord fabric, D is the maximum deviation value between the set cord fabric length L and the actual cord fabric length, and C is equal to W / tanα - L - D - B. The deviation of the first side 10 of the cord fabric is corrected within the deviation correction length, and the deviation correction of the cord fabric is stopped within the non - deviation correction length. Moreover, the deviation of the first side 10 is corrected first, and the deviation correction of the first side 10 is stopped after the deviation correction of the first side 10 is completed.

[0038] Specifically, during the process of correcting the deviation of the first side 10 and the second side 20, the deviation is corrected respectively by half of the set cord fabric width W. It should be noted that for the deviation correction device in this application, two deviation correction lenses can be set to correct the deviation of the first side 10 and the second side 20 of the cord fabric respectively.

[0039] Moreover, in this application, the second preset length A is related to the system response time, the scanning period, and is also related to the change amount of the material width per unit length. The above - mentioned B is related to the theoretical material length and the actual material length, and is related to the actual material width, angle, and the theoretical width and angle.

[0040] Meanwhile, in this application, when the set cord fabric width W of the cord fabric does not match the actual width, the deviation is corrected with the actual width of the cord fabric.

[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0042] 1. When the width of the cord fabric changes, the deviation correction controller can normally correct the deviation in different zones, fit properly, and does not affect the fitting effect;

[0043] 2. The deviation sizes of multiple zones can be adjusted through parameters, and it can adapt to the deviation correction of more complex cord fabrics in more situations.
