At this time, the push rod of the double-output shaft pushing cylinder 113 pushes the pushing plate 114 to push the connecting sleeve 100 out of the discharging port 112 into the inclined material guiding conveying groove body 20, and it is conveyed to the right along with the inclined material guiding conveying groove body 20 (the left end of the inclined material guiding conveying groove body 20 is higher than the right end). The sensing end of the second proximity switch 22 senses the connecting sleeve 100, indicating that the connecting sleeve 100 has passed. When it moves to the outlet end of the inclined material guiding conveying groove body 20, the sensing end of the third proximity switch 3 is reached. At this time, the push rod of the pressing cylinder 24 pushes to press the elastic block 25 against the top surface of the connecting sleeve 100 at this position, fixing it for 2 to 3 seconds. Then, the push rod of the pressing cylinder 24 is retracted, and at this time, one of the arc-shaped discharging grooves 161 of the rotating disc 16 is close to the discharging port of the inclined material guiding conveying groove body 20. At this time, the connecting sleeve 100 falls into the arc-shaped discharging groove 161, and the subsequent connecting sleeve 100 moves to the right and is sensed by the sensing end of the third proximity switch 3. The push rod of the pressing cylinder 24 pushes the elastic block 25 to press against the top surface of the connecting sleeve 100 at this position, fixing it.

[0034] And the connecting sleeve 100 in the arc-shaped feeding recess 161 is pushed by the detection cylinder 29 to make the detection pressing block 292 press against the rear end face of the connecting sleeve 100 to move it forward, and the front end of the connecting sleeve 100 presses against the rear end face of the front limiting column 261. At this time, the length of the connecting sleeve 100 can be measured by the movement of the detection block of the grating ruler 28 to determine whether it meets the requirements. If it meets the requirements, the rotating disc 16 is rotated by driving the servo motor 15 to rotate one station (i.e. the position of one arc-shaped feeding recess 161) at a time. The connecting sleeve 100 that meets the requirements can be continuously rotated by the rotating disc 16 to move to the right and finally enter the second inclined material guide groove body 30.

[0035] The unqualified products are pushed out of the arc-shaped feeding recess 161 by the waste pushing cylinder 141 after the rotating disc 16 is rotated by driving the servo motor 15 to rotate one station, and then enter the waste guide groove body 80 for direct discharge.

[0036] After the qualified products enter the second inclined material guide groove body 30, they are conveyed to the right along the second inclined material guide groove body 30 and are sensed by the fifth proximity switch 6, indicating that the connecting sleeve 100 passes through. Then, the connecting sleeve 100 enters the arc-shaped recess 41 and is sensed by the sixth proximity switch 8.

Then, the push rod of the grabbing cylinder 51 is pushed to make the elastic clamping block 52 clamped in the inner annular groove at the front end of the connecting sleeve 100, and the connecting sleeve 100 is pushed backward to insert into the insertion column 421 to press the rear end face of the connecting sleeve 100 against the front wall face of the supporting block 42 to realize positioning. Then, the push rod of the punching cylinder 431 is pushed to make the punching head 45 quickly descend to punch the middle part of the top surface of the connecting sleeve 100, and the punched waste and the punching head 45 are inserted into the corresponding vertical through hole 422 to realize punching. After completion, the push rod of the grabbing cylinder 51 is retracted. Since the elastic clamping block 52 is clamped on the connecting sleeve 100, the push rod of the grabbing cylinder 51 retracts to pull the connecting sleeve 100 forward. After the front end of the connecting sleeve 100 is blocked by the blocking sleeve 4, the push rod of the grabbing cylinder 51 continues to retract. At this time, the connecting sleeve 100 is separated from the elastic clamping block 52, and the connecting sleeve 100 falls from the vertical through groove of the grabbing frame 50 to the top surface of the top plate of the lower rack 10 and is placed in the material guide groove body. The connecting sleeve 100 can flow out along the front end of the material guide groove body and be collected by placing a material collecting frame body below the front end of the material guide groove body. The subsequent connecting sleeve 100 can be processed in turn, and the processing effect is good, the efficiency is high, and the labor intensity is greatly reduced.
