[0012] 1. By setting a spring, the bottom of the test wheel is placed on the surface of the copper busbar. The elastic force of the spring drives the telescopic column to move downward. The telescopic column drives the support column and the test wheel to move downward, so that the bottom of the test wheel is in close contact with the surface of the copper busbar. When the surface of the copper busbar is uneven, the test wheel will float up or down to adapt, thereby improving the accuracy of the test.

[0013] 2. By setting up a testing mechanism, the electric push rod extends to move the sleeve frame, which in turn moves the support column and the testing wheel, causing the testing wheel to roll along the surface of the copper busbar. The support column moves the drawing pen synchronously, and the drawing pen draws lines on the surface of the drawing paper. By comparing the drawn lines with the horizontal line on the surface of the drawing paper, the flatness of the copper busbar surface is determined. The testing of the copper busbar surface is completed in one go, improving the ease of use of the testing equipment. Attached Figure Description
