Step 4: drag chain: the driving assembly 64 drives the manipulator assembly 62 to approach the front end of the chain belt 8 until the chain belt 8 enters between the first upper gripper 6222 and the first lower gripper 6223 of the front gripper group 622 and between the second upper gripper 6232 and the second lower gripper 6233 of the rear gripper group 623 along the width, and then the front gripper driving cylinder 6224 and the rear gripper driving cylinder 6234 are both extended, so that the front gripper group 622 and the rear gripper group 623 both generate clamping action, and the chain belt 8 is clamped;

then, the branch chain driving telescopic cylinder drives the branch chain thin plate 31 to ascend until the top end of the branch chain thin plate 31 is positioned above the top surface of the base 212;

the driving assembly 64 drives the manipulator assembly 62 to move away from the chain belt feeding mechanism 21 in the opposite direction, the opening and closing guide wheel 69 rolls along the profiling guide plate 13, when the opening and closing guide wheel 69 rolls along the first narrow part 131 to the wide part 132, the front gripper seat 6221 and the rear gripper seat 6231 are away from each other, the front gripper group 622 and the rear gripper group 623 are opened along the width direction of the chain belt 8, so that the engaged chain belt 8 is separated into two chain separating belts, and the separated chain separating belts pass through the chain separating thin plates 31 from two sides of the chain separating plates respectively;

when the opening and closing guide wheel 69 rolls from the wide portion 132 to the second narrow portion 133, the front gripper set 622 and the rear gripper set 623 respectively approach each other under the elastic force of the front elastic element 6228 and the rear elastic element 6236, so as to drive the two chain dividing belts to approach each other and respectively enter the chain conveying channels 4214 at two sides of the chain dividing convex edge 4213.

The branch chain driving telescopic cylinder drives the branch chain thin plate 31 to descend until the top end of the branch chain thin plate 31 is positioned below the top surface of the base 212;

the driving assembly 64 continuously drives the manipulator assembly 62 to be far away from the chain belt feeding mechanism 21, the two chain belt branches enter the introducing port 93 of the slider 9, and the two chain belt branches penetrate through the engaging port 94 and the chain closing port 4222 after passing through the slider 9, so that the head penetrating action is completed.

Step 5: the angle telescopic cylinder descends to drive the driving block 462 to descend, so that the second pull head die holder 422 is separated from the first pull head die holder 421;

the driving assembly 64 continues to drive the robot assembly 62 away from the chain feeding mechanism 21, so that the slider 9 is disengaged from the first groove until the position sensor 67 reaches the first mark position sensor 65, and the lifting hydraulic cylinder 54 drives the housing 53 to descend to cut off the chain 8;

when the position sensor 67 reaches the position of the second mark position sensor 66, the front gripper driving cylinder 6224 and the rear gripper driving cylinder 6234 both operate, so that the front gripper group 622 and the rear gripper group 623 respectively open under the elastic action of the first gripper resetting elastic member and the second opening and closing resetting elastic member, and the clamping of the chain belt 8 is released;

the driving assembly 64 continues to drive the manipulator assembly 62 to move 5-10cm away from the chain feeding mechanism 21, so that the chain belts 8 with the pull heads 9 threaded thereon fall off from the front gripper group 622 and the rear gripper group 623, the chain belts 8 fall on the conveyor belts, and the conveyor belts convey the chain belts 8 with the pull heads 9 threaded thereon to the accommodating grooves 14.
