[0022] It should be noted that when the color difference test is performed on the coating machine substrate sample, the device can be used to operate, first, the mounting part 1 is placed in the desired position, then the substrate sample is clamped on the clamp 7, then according to the specific circumstances of the test required, the first color difference tester 4 and the second color difference tester 5 are opened in turn, and the color difference test is performed on the substrate sample. It should be noted that the first color difference tester 4 and the second color difference tester 5 are not the same light source. Such a setting can better test the color difference value of the substrate according to the light source. Then start the double-shaft screw motor 2, so that the output shaft of the double-shaft screw motor 2 drives the double-shaft screw to rotate, so that the first connecting part 3 slides to both sides by the guide groove. At this time, the test light 51 in the first color difference tester 4 and the second color difference tester 5 records the data of the camera 52 with the distance from the substrate sample becoming farther and farther away, so as to test the substrate sample at different distances. When the intensity of the test light 51 is not enough or the light source around the mounting part 1 is complex, the function of the fill light 53 can be used to strengthen the aperture brightness of the test light 51, so as to better help the test light 51 increase the intensity.
