Description

Technical Field

[0001] The present invention relates to the technical field of busbar bending, and in particular to a visual compensation method and a compensation system for busbar bending. Background Art

[0002] In modern industrial manufacturing, the efficient operation of the power system depends on the precise processing of the busbar. As a key component of power transmission, the bending accuracy of the busbar directly affects the stability and safety of the system. Traditional busbar processing methods mainly rely on manual operation or semi-automatic equipment, which have certain limitations in efficiency and accuracy.

[0003] Existing busbar bending equipment requires manual setting of the bending compensation angle and relies on the operator's experience for adjustment. This method is not only time-consuming but also prone to errors. Especially in mass production, the accumulation of errors leads to serious quality problems.

[0004] Based on this, the present invention designs a visual compensation method and compensation system for busbar bending to solve the above problems. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a visual compensation method for busbar bending, the method comprising step 1, turning on the machine; step 2, querying the bending compensation value of the corresponding copper busbar; step 3, inputting the compensation value into the bending equipment according to the queried compensation value, and adjusting the bending parameters of the bending equipment according to the adjusted compensation value; step 4, performing the first bending; step 5, visually photographing and measuring, and performing the first measurement of the curvature of the bent copper busbar; step 6, recording various parameters of the first bending; step 7, judging whether the bending is qualified, if qualified, entering step 8, if unqualified, entering step 9; step 8, ending the bending; step 9, calculating the compensation value again, and then entering step 10; step 10, bending again; step 11, visually photographing and measuring the copper busbar bent again; step 12, recording various parameters of the second bending; step 13, judging whether the second bending is qualified, if qualified, entering step 8, if unqualified, entering step 9.

[0006] Further, querying the bending compensation value of the corresponding copper busbar includes: detecting and querying a compensation value corresponding table, and querying the compensation value from the compensation value corresponding table according to the width, thickness, and target angle information of the current bent busbar.

[0007] Furthermore, various parameters of the first bending are recorded, including establishing a first bending model, and inputting the current compensation value, measurement angle, target angle, busbar width, and thickness into the first bending model.

[0008] Furthermore, various parameters of the first bending are recorded, including the parameters of the first bending model update, and the compensation value is calculated, and the calculated compensation value is recorded in the compensation value corresponding table.

[0009] Further, it is determined whether the bending is qualified, including whether the bending angle is qualified. When the deviation between the measured bending angle and the target angle is less than 0.2°, it is qualified, and the process goes to step 8. If the deviation is greater than 0.2°, it is unqualified, and the process goes to step 9.

[0010] Furthermore, the compensation value is calculated again, including establishing a re-bending model, inputting the angle deviation value, busbar width, and thickness into the re-bending model, and calculating the compensation value required for the re-bending.

[0011] Furthermore, various parameters of the re-bending are recorded, including updating the re-bending model, feeding back the measured values ​​after the re-bending to the re-bending model, and updating the model parameters.

[0012] Furthermore, a visual compensation system for busbar bending is provided, the system comprising: a copper busbar bending module, for bending the copper busbar; an image acquisition module, for collecting the appearance of the copper busbar in the corresponding process by photographing; an image processing module, for measuring various parameters of the copper busbar, calculating the values ​​of various parameters of the copper busbar, and establishing a corresponding bending model; an image compensation module, for calculating the difference in corresponding parameters based on the comparison of various parameters of the target bending model with those of the bending model.

[0013] Furthermore, in the image processing module, the specific algorithm is: obtaining the mask of the area where the copper busbar is located through the deep learning model, calculating the straight line segment area in the mask using the straight line fitting method, calculating the boundary position of the copper busbar in the straight line segment area, fitting a straight line to the boundary, and obtaining the straight line angle.

[0014] In summary, the present application has the following beneficial technical effects: the visual compensation method and system of the present invention detects the bending angle of the busbar in real time, automatically calculates and adjusts the compensation angle, thereby improving the bending accuracy and production efficiency, and effectively overcoming the precision problem in processing.

[0015] The system is highly intelligent and easy to operate, which reduces dependence on manual labor and significantly reduces production and maintenance costs. It also avoids the need to adjust accuracy through manual comparison and improves the accuracy of copper busbar production.

[0016] The system continuously updates the best bending model and timely updates the compensation parameters of the same raw material during bending, so that only one bending compensation is required during bending, or even no bending compensation is required to meet the standard directly, which greatly improves production efficiency and busbar accuracy and effectively avoids the number of busbar corrections.
