[0025] Please refer to Figure 3 As shown in the figure, the grabbing mechanism 4 includes base plate 41, grabbing jig 42 and driving cylinder two 43, the base plate 41 is connected to the X-axis slide rail 21, the grabbing jig 42 is arranged on the base plate 41, the driving cylinder two 43 is drivingly connected to the grabbing jig 42, the grabbing jig 42 is provided with a grabbing piece 44, and the grabbing piece 44 is a suction nozzle piece.

[0026] Please refer to Figure 4As shown, the detection mechanism 6 includes a detection jig 61, a tongue block 62, and a driving cylinder one 63. The detection jig 61 is provided with a sliding groove 611 in which the tongue block 62 is slidably arranged. The tongue block 62 is slidably arranged in the detection jig 61 and is provided with a plurality of recesses 621 for placing products. The tongue block 62 is connected with a transmission block 65 through a transmission rod 64, and the output end of the driving cylinder one 63 is connected with the transmission block 65. The tongue block 62 is driven to move by the driving cylinder one 63, so that the recesses 621 on the tongue block 62 are aligned with the imaging area of the image acquisition device 5. The above design meets the requirement that multiple products are placed in the tongue block 62 at the same time. The tongue block 62 is driven to reciprocate in the detection jig 61 by the driving cylinder one 63, so that each product on the tongue block 62 is aligned with the image acquisition device 5 in turn.
