[0044] Example 2

[0045] As Figures 7-8 shown, in order to guarantee sample 3 when placing to positioning clamp, since the positioning error of articulated robot 1 causes the condition that the processing thickness of left and right sides processing surface is not same, the secondary positioning mechanism is still provided in the embodiment, specifically, the outer surface center of positioning block 19 is vertically engraved with 0.2mm wide positioning reference line groove 20, and the positioning reference line groove 20 is filled with fluorescent nano coating (wavelength 520nm green light).

[0047] When the articulated robot 1 clamps the sample 3 to the positioning fixture, the photoelectric sensor 22 is just located outside the positioning block 19 and will detect the positioning reference line groove 20 on the surface of the positioning block 19. The fluorescent nano coating in the positioning reference line groove 20 will generate longer wavelength fluorescence after being irradiated by the excitation light of the photoelectric sensor 22. The narrowband filter is arranged in front of the photoelectric sensor 22 and only allows the wavelength of the generated fluorescence to pass through and blocks other light. The horizontal movement compensation of the articulated robot 1 ensures that the sample 3 is in the central position of the positioning block 19 in the horizontal direction. When the fluorescent intensities sensed by the two photoelectric sensors 22 both reach the set requirement, that is, the middle part of the positioning block 19 is at the rotation center of the L-shaped plate 4, it can be ensured that the sample 3 is just at the center of the positioning block 19. Through the secondary positioning mode, it is ensured that the machining thicknesses of the two side machining surfaces of the end-quenching sample are within the specified error range.
