As shown in fig. 1 and 2, the first surface of the part faces upward and penetrates through the profiling hole 11 of the grinding jig disc, and the position of the first surface is matched with the front position of the grinding jig disc 2 (for example, at the same horizontal plane), and the second surface of the part is distributed around the second surface, so that the second surface is located below the back surface of the grinding jig disc 2 and just abuts against the back surface of the grinding jig disc 2, and meanwhile, the positioning pin 12 at the corresponding position penetrates through the positioning hole, so that the carrier disc 2 is fixed and limited on the jig table 1.

Then, the manipulator drives the suction claw to move to the position above the jig table 1 and gradually move downwards so that the first suction nozzle 41 and the second suction nozzle 42 respectively suck the grinding jig disc 2 and the part, and the pressing block 44 abuts against the grinding jig disc 2 at the moment so as to ensure that the part and the grinding jig disc 2 keep relatively static and cannot be loosened; the manipulator drives the adsorption device adsorbing the grinding jig disc 2 and the parts to move to the grinding disc (not marked), and the manipulator drives the adsorption device to leave.

As shown in fig. 3 and 4, after the part is ground, the part is continuously magnetically adsorbed and fixed by the grinding plate, and the manipulator makes the adsorption device approach the part and the grinding jig plate 2 downward along the vertical direction, so that the first suction nozzle 41 and the second suction nozzle 42 respectively adsorb the grinding jig plate 2 and the part and move to a good product area and a bad product area. In the process of adsorbing the parts and grinding the jig disc 2, the pressing block 43 applies an acting force opposite to the suction nozzle to the grinding jig disc 2 to ensure that the parts and the grinding jig disc 2 are relatively static and cannot be loosened. When the parts and the grinding jig disc 2 are adsorbed or the parts and the grinding jig disc 2 are transferred, good products and inferior products of the parts are also detected. The method specifically comprises the following steps: the driving motor 32 is started, the driving rod 321 is driven by a belt between the rotating shafts 313 to drive the connecting rod 314 to rotate, and then the annular guide rail 5 is driven to rotate, so that the brightness detection head 51 on the annular guide rail 5 sequentially rotates to the position of the corresponding laser sensor 6, after the laser sensor 6 at the corresponding position detects that the brightness detection head 51 is in place, a signal is sent to the controller, the controller sends an instruction to shut down the driving motor 32 and times for staying for a fixed time, at the moment, the brightness detection head 51 detects the brightness of the grinding part at the corresponding position, and sends a brightness value data signal to the controller, and the controller judges whether the brightness of the corresponding part meets a preset threshold value according to the received numerical value signal, so that whether the part is good.

When the defective part is transferred to the defective part area, the second suction nozzle 42 corresponding to the defective part is controlled to release the part, so that the defective part is placed in the defective opening area. When the grinding jig disc is transferred to the grinding jig disc placing area, the controller controls the third suction nozzle 41 to loosen the grinding jig disc 2, so that the grinding jig disc 2 is placed in the grinding jig disc placing area.

Referring to fig. 3 and 4, the rotating shaft 313 and the fixing plate 312 are connected by the first bearing assembly, the rotation of the rotating shaft 313 does not drive the outer ring of the first bearing assembly to rotate, even if there is a trend of relative movement, because the part and the grinding jig disc 2 are positioned by abutting against each other, and the part and the grinding disc are fixed by magnetic attraction, and are fixed by air pressure adsorption with the second suction nozzle 42, therefore, the grinding jig disc 2 cannot be driven by the first suction nozzle 41 to rotate under the condition that the fixing plate 312 has a rotating force, i.e. when the ring-shaped guide rail 5 rotates, the fixing limit of the part can be ensured, the position of the part cannot be shifted, the situations of false detection, missed detection and repeated detection can be prevented, and the detection can be carried out smoothly.
