Please refer to Fig. 1 and Fig. 2 to illustrate, and in the present embodiment, the specific working process of this automatic milling material head mechanism is:

The manipulator takes out the product 10 in the molding machine, and places the product 10 on the positioning jig 220. At this time, the sensor on the positioning jig 220 senses the product 10, and sends a signal to control the piston of the positioning cylinder 221 to stretch out to Product 10 fixed. The piston of the positioning cylinder 221 stretches out to trigger the movement of the first traverse cylinder 210, and the first traverse cylinder 210 moves horizontally until it moves to the bottom of the lifting mechanism. At this time, the piston of the lifting cylinder 321 is triggered to eject, thereby driving the motor 331 and the punching mechanism. Material head cylinder 332 moves down. After the lifting cylinder 321 has finished moving, the piston of the punching head cylinder 332 is triggered to push out, thereby driving the punching head structure 3320 to break the material head connected to the surface of the product 10, and the punching signal triggers the piston of the positioning cylinder 221 to return. At the same time, the motor 331 is triggered to start rotating, thereby driving the eccentric wheel 3310 under the motor 331 to move, and the eccentric wheel 3310 drives the grinding head 3311 to polish the product 10, and repeatedly polishes it several times until the set time. the

When the set time is reached, the piston of the first screw head cylinder 410 is triggered to push out, thereby driving the screw head mechanism to move upward. After the piston of the first twisting head cylinder 410 has moved through the stroke, the piston of the second screwing head cylinder 430 is triggered to stretch out, thereby driving the rack 4311 to move in a straight line, and the rack 4311 drives the gear to rotate, thereby Drive the shearing shaft 4310 to rotate and twist off the material head inserted in the shearing shaft 4310, repeat several times until reaching the set time. If in order to make the effect of screwing the material head better, after the material cutting shaft 4310 is twisted off the material head, the piston of the three-axis cylinder 440 is triggered to eject back and forth, thereby driving the high-speed motor 450 to move back and forth under the positioning fixture 220, and then drive the ball The head milling cutter further mills off the head residue. the

After the screw head mechanism is reset, the first traverse cylinder 210 continues to drive the positioning jig 220 to move forward, and at the same time triggers the second traverse cylinder 560 to drive the product suction mechanism to move toward the traverse mechanism. The piston of the product suction cylinder 550 is triggered to extend out. After the piston of the product suction cylinder 550 completes its stroke, the vacuum generator is triggered to absorb the product 10 through the suction cup 541. When the vacuum detection value is reached, the product suction mechanism resets and simultaneously triggers the second The traverse cylinder 560 drives the product 10 adsorbed on the suction cup 541 to move away from the traverse mechanism to the next processing area. the
