[0028] In addition, the first and second sharp parts 3421 and 3422 described in the embodiment are all isosceles trapezoidal in cross section, as shown in Figure 3 The cross-sectional areas of the plurality of first sharp parts 3421 are equal, and the lengths are different, as shown in Figure 4 The cross-sectional areas of the plurality of second sharp parts 3422 are different, and the lengths are equal.

[0029] Specifically, the powder coated substrate to be tested is placed on the clamp assembly 22, and the lateral sliding module 21 can drive the clamp assembly 22 and the substrate to move, and when it moves to a preset position (close to the wheel body 342) (this working condition can be obtained through a position sensor), the rotating driver 343 drives the wheel body 342 to rotate, so that a second sharp part 3422 is opposite to the substrate, and then the test assembly 34 is driven to move by the fixing mechanism 3, so that a second sharp part 3422 is in contact with the substrate, and then the lateral sliding module 21 is used to drive the substrate to move, so that a second sharp part 3422 and the substrate move relative to each other.

[0030] The test assembly 34 is reset by the fixing mechanism 3, the rotating driver 343 drives the wheel body 342 to rotate, and another second sharp part 3422 is opposite to the substrate, and the above steps are repeated.

[0032] After the plurality of second sharp parts 3422 complete the test on the substrate, the plurality of first sharp parts 3421 continue to test the powder coating on the surface of the substrate, the fixing mechanism 3 drives the test assembly 34 to be in contact with the surface of the substrate, the rotating driver 343 drives the wheel body 342 to rotate, so that a first sharp part 3421 is opposite to the substrate, the rotating driver 343 slowly rotates, the plurality of first sharp parts 3421 move relative to the substrate, the lengths of the plurality of first sharp parts 3421 are different, the pressures between the substrate and the plurality of first sharp parts 3421 are different, after the substrate and the plurality of first sharp parts 3421 move relative to each other, scratches appear on the surface of the substrate, and relevant technical personnel record the data to obtain a plurality of groups of data.
