The second transfer mechanism (7) is arranged beside the third turntable (81). The laser engraving machine (82) is arranged above the third turntable (81). Four second positioning grooves (83) capable of placing products are arranged around the axis of the top surface of the third turntable (81). The products can move directly below the laser engraving machine (82) under the drive of the third turntable (81). The laser engraving machine (82) can emit laser light to the products and mark the products.

9. The automatic injection molding and detection mechanism according to claim 8, wherein: The second transfer mechanism (7) includes a second robotic arm and a sixth suction cup. The sixth suction cup is fixed to the end of the second robotic arm. After the sixth suction cup sucks the products at the discharging end of the injection molding machine (6), it can move above the second positioning groove (83) under the drive of the second robotic arm. The sixth suction cup can place the products so that the products enter the second positioning groove (83).

10. The automatic injection molding and detection mechanism according to claim 9, wherein: The detection module (9) includes a third robotic arm (91), a seventh suction cup, a fourth turntable (92), and a camera (94). The seventh suction cup is fixed to the end of the third robotic arm (91). The third robotic arm (91) is arranged beside the fourth turntable (92). The camera (94) is arranged above the fourth turntable (92). Four third positioning grooves (93) for placing products are arranged on the top surface of the fourth turntable (92) around its own axis. The seventh suction cup can suck the product marked in the second positioning groove (83) and move above the third positioning groove (93) under the drive of the third robotic arm (91). The seventh suction cup can release the product so that the product enters the third positioning groove (93). The product can move under the drive of the fourth turntable (92) to directly below the camera (94), and the camera (94) can perform visual inspection on the product.
