A diamond setting method for an automatic diamond setting device, characterized in that: Using the automatic diamond setting device according to any one of claims 2 to 5, the method comprises the following steps: S1: The robot (21) moves to the position of the ring blank loading fixture (1), penetrates into the ring blank (200) through the outer side of the expansion claw (2-51), opens the expansion claw (2-51) through the driving cylinder (81), and abuts against the inner end of the ring blank (200) to clamp the ring blank (200), and contacts the axial side of the ring blank (200) through the detection head of the digital micrometer to perform axial rough positioning of the ring blank (200), and the axial rough positioning value range is ±0.5mm, and contacts the radial side of the ring blank (200) through the positioning needle to perform radial rough positioning of the ring blank (200), and the radial rough positioning value range is ±0.2mm, and contacts the two axial sides of the ring blank (200) through the edge finder to accurately determine the machining center position of the slotting mechanism (4); S2: The ring blank (200) is transported to the position of the slotting tool (4143) by the manipulator (21), and the material taking expansion fixture (22) is driven to rotate by the manipulator (21) so as to drive the ring blank (200) to rotate, and the set slotting tool (4143) is used to process the ring blank (200) into an annular inlay groove (210), wherein the processing depth range of the tool inlay groove (210) is 0.4-0.5 mm, and the number of inlay grooves (210) distributed in the ring blank (200) in the reversing direction is 18±2; S3: grinding the edge of the inlay groove (210) by means of a grinding head (422) to remove edge burrs, wherein the rotation speed of the grinding head (422) is 65000±1000 rpm; S4: The material tray fixture (5-32) is moved to a position below the patch suction nozzle (612) through the X-axis loading linear module and the Y-axis loading linear module, a diamond raw material (300) is sucked through the patch suction nozzle (612), and then the material tray fixture (5-32) is removed; S5: The driving cylinder (81) drives the support block (82) to move to one side of the drilling mechanism (6), and the manipulator (21) moves the ring blank (200) after the groove (2-11) to the position of the drilling mechanism (6). The material expansion clamp (22) is supported by the support seat (822), and the positioning sensor (34) touches the boss edge of the setting groove (210) to determine the position of the setting groove (210) to be set. The suction range of the patch suction nozzle (612) is -90-0Kpa, and the patch suction nozzle (612) takes the diamond The raw material (300) is placed on the setting groove (210), and the pressing rod (621) is pressed downward, with a pressure range of 60±10N and a pressing speed of 1±0.05mm / s. The side end portion of the ring blank can be embedded in the pressing groove (622), and the diamond raw material (300) is pressed into the setting groove (210) through the pressing groove (622). The ring blank (200) is rotated by the manipulator (21), and the diamond setting is repeated, thereby completing the circumferential diamond setting of the entire ring blank (200), and then the material is unloaded to the ring blank loading fixture (1) by the manipulator (21).
