Each sliding block of the rodless cylinder (241) is provided with a transfer plate (242). Each right side of the transfer plate (242) is provided with an electric track (243). The sliding blocks of the electric track (243) are connected to a lifting plate (244). A rotating disk (245) is rotatably arranged at the bottom center of the lifting plate (244). A servo motor (246) is arranged on the side of the lifting plate (244). The servo motor (246) and the rotating disk (245) transmit power through the transmission structure II (247).

7. A vision-guided multi-angle marking and positioning device according to claim 6, characterized in that, The adjustment mechanism (24) also includes a bidirectional screw (2411) rotatably mounted on the bottom of the rotating disk (245). The bidirectional screw (2411) is installed parallel to the sliding direction of the slider (249). The threads on both sides of the bidirectional screw (2411) are connected to clamps (2412) by threads. The clamps (2412) are installed parallel to the bottom of the rotating disk (245). The slider (249) protrudes outward on the side facing the screw. The inner side of the clamps (2412) fits against the outer side of the protruding position of the slider (249).

8. The vision-guided multi-angle marking and positioning device according to claim 7, characterized in that, It also includes a baffle mechanism (27) set at the discharge port of the conveying mechanism (23). The baffle mechanism (27) includes guide optical shafts (271) symmetrically arranged on the mounting plate (232) below the discharge port. A wedge block (272) is slidably connected between the guide optical shafts (271). The wedge block (272) extends upward through the mounting plate (232). The edges of the wedge block (272) facing the material are rounded or beveled. A compression spring (273) is connected between the wedge block (272) and the guide optical shaft (271).

9. A vision-guided multi-angle marking and positioning device according to claim 6, characterized in that, The clamp (248) is rotatably connected to the slider (249). A torsion spring (210) is provided at the rotatable connection between the clamp (248) and the slider (249). The outer side of the clamp (248) above the inclined plane is provided with meshing teeth (211), and the inclined plane of the meshing teeth (211) faces downward.

10. A vision-guided multi-angle marking and positioning device according to claim 9, characterized in that, It also includes a sliding shaft (212) located on the right side of the clamping rod (248). A row of inclined grooves (213) is provided on the unloading rod (25) on the right side of the sliding shaft (212). During the upward movement of the clamping rod (248), the sliding shaft (212) will enter the groove (213).
