A material transfer clamping mechanism is provided at the bottom of the feed station. A tip clamping mechanism and a chuck clamping mechanism are sequentially provided directly above the material transfer clamping mechanism. The tip clamping mechanism is driven and connected by a tip lifting mechanism, which is connected to a tip counterweight mechanism. The chuck clamping mechanism is driven and connected by a chuck lifting mechanism, which is connected to a chuck counterweight mechanism. A loading detection assembly is provided beside the bottom of the feed station, a slot detection assembly is provided beside the top of the feed station, and a cutting mechanism is provided beside the feed station. The cutting mechanism is driven and connected by a cutting lifting mechanism, which is connected to a cutting counterweight mechanism.

The cutting tool is provided with a thermocouple sensor. The end of the dust collection tube 32 has a certain bending angle to improve slag suction. The thermocouple sensor is specifically mounted on the tool handle.

[0048] like Figure 2 and 3As shown, the material transfer and clamping mechanism includes a turntable 2 fixed to the bottom of the frame 1. A vertically hinged shaft 3 is formed inside the turntable 2. The shaft 3 extends out from the top surface of the turntable 2 and is fixedly connected to a support chuck 4. The support chuck 4 has a plurality of pneumatic clamps arranged in a circular array along its circumference. A large pulley 7 is fixedly mounted on the shaft 3. A rotating motor 5 is fixedly mounted inside the frame 1. A small pulley 6 is fixedly mounted on the shaft of the rotating motor 5. A belt is tensioned and connected between the small pulley 6 and the large pulley 7.

[0049] like Figure 4 As shown, the tip clamping mechanism includes a tip seat 8, on which is mounted a tip pressing cylinder 9, the downward-facing pressing rod of which is rotatably sleeved onto a tip pressing cylinder 10. When the bottom end of the charge is clamped and fixed, the tip seat 8 is lowered to an appropriate position, and the tip pressing cylinder 9 extends its pressing rod downward until the tip pressing cylinder 10 presses on the top end of the charge, thereby clamping and fixing the charge from top to bottom.

[0050] like Figures 6 to 8 As shown, the top lifting mechanism includes a top motor 13 fixedly mounted on the frame 1, the top motor 13 is connected to the top screw 14, the outer periphery of the top screw 14 is sleeved with the top nut to form a threaded engagement connection, the top nut is fixedly connected to the top lifting plate, a vertical rail 1 is fixedly provided on the frame 1, a vertical block 1 is correspondingly provided on the top lifting plate, the vertical block 1 is clamped with the vertical rail 1 to form a guide sliding connection, and the top lifting plate is fixedly mounted with a top seat 8; the top motor 13 is started to drive the top screw 14 to rotate, and the top lifting plate is driven to slide up and down along the vertical rail 1 through the threaded engagement transmission, thereby synchronously driving the top clamping mechanism to move up and down.

[0051] The top counterweight mechanism includes two pairs of top sprockets 15 horizontally hinged to the frame 1. Each pair of top sprockets 15 is connected to a top chain 16 through tooth meshing. One end of the top chain 16 is suspended from a top counterweight group 17 located within the frame 1, and the other end of the top chain 16 is connected to the top lift plate. As the top lift plate moves up and down, it pulls the top chain 16 and the top sprockets 15 in a synchronous reciprocating motion, thereby synchronously pulling the top counterweight group 17 up and down, acting as a balancing counterweight.

[0052] like Figure 5 As shown, the chuck clamping mechanism includes a chuck support 11, mounted on a hollow chuck 12. The hollow chuck 12 has a central opening and a plurality of pneumatic grippers arranged in a circular pattern around the central opening. The charge passes through the central opening of the hollow chuck 12, where the pneumatic grippers clamp the charge circumferentially, securing it. A planar bearing is mounted within the hollow chuck 12, and through the rolling contact of the bearing, the hollow chuck 12 is driven by an external force to rotate.

[0054] The chuck counterweight mechanism includes two pairs of chuck sprockets 20 horizontally hinged to the frame 1. Each pair of chuck sprockets 20 is connected to a chuck chain 21 through meshing teeth. One end of the chuck chain 21 is suspended from a chuck counterweight assembly 22 located within the frame 1, and the other end of the chuck chain 21 is connected to the chuck lift plate. As the chuck lift plate moves up and down, the chuck chain 21 and the chuck sprockets 20 are meshed and reciprocated, thereby synchronously pulling the chuck counterweight assembly 22 up and down, acting as a counterweight.

[0055] The top motor 13 and the top screw 14 are arranged from top to bottom, and the chuck motor 18 and the chuck screw 19 are arranged from bottom to top. The two are arranged in a relatively staggered manner. The chuck counterweight mechanism is arranged on the outer ring of the top counterweight mechanism. The top lifting mechanism and the chuck lifting mechanism share the same vertical rail structure. The arrangement and assembly reasonably utilize the layout space of the frame 1, so that the top lifting mechanism and the chuck lifting mechanism operate independently and do not interfere with each other.

[0056] like Figure 1 As shown, the loading detection component includes a detection bracket 1, on which a camera 33 and a light source 1 are installed; the slot detection component includes a detection bracket 2, on which a camera 34 and a light source 2 are installed.

[0058] The feed motor 24 is activated to rotate the feed screw 25, which, through threaded engagement, drives the feed base 28 to slide horizontally along the cross rail 26, simultaneously driving the cutter to adjust the feed distance. Stops 27 are installed at both ends of the cross rail 26, creating extreme stoppages for the feed base 28. During the cutting process, the suction of the dust pipe 32 removes the cutter waste.

[0059] like Figure 1 and Figures 6 to 8 As shown, the cutting lifting mechanism includes a cutting motor 36 fixedly mounted on the frame 1, the cutting motor 36 is connected to the cutting screw 37, the outer periphery of the cutting screw 37 is sleeved with a cutting nut to form a threaded engagement connection, the cutting nut is fixedly connected to the cutting base plate 23, a vertical rail 2 is fixed on the frame 1, a vertical block 3 is correspondingly provided on the cutting base plate 23, and the vertical block 3 is correspondingly clamped with the vertical rail 2 to form a sliding connection; the cutting counterweight mechanism includes two pairs of cutting sprockets horizontally hinged on the frame 1, each pair of cutting sprockets is connected to a cutting chain 38 through tooth engagement, one end of the cutting chain 38 is hoisted to the cutting counterweight group located in the frame 1, and the other end of the cutting chain 38 is connected to the cutting base plate 23.

As the cutting base plate 23 moves up and down, the cutting chain 38 is simultaneously pulled back and forth with the cutting sprocket, meshing with the teeth, thereby simultaneously pulling the cutting counterweight assembly up and down, acting as a counterweight.
