The principle of the utility model is as follows: the rivet pulling part is linearly arranged, namely, the rivet pulling second cylinder is arranged on the rivet pulling installation base plate through a rivet pulling second cylinder fixing piece, and the rivet pulling first cylinder is arranged on the rivet pulling installation base plate through a rivet pulling first cylinder installation block and is in a same line with the rivet pulling second cylinder. The rivet pull rod is connected with one end of a piston rod of the rivet pulling second cylinder through a first floating joint, and the rivet pulling top block is fixed at the other end of the piston rod of the rivet pulling second cylinder. When the piston rod of the first pull rivet cylinder extends out, the piston rod is used as the middle limit of the second pull rivet cylinder, and when the rivet is pulled to the middle limit, diameter detection and short rivet detection can be performed. The rivet diameter detection part and the rivet pulling part are arranged on the main mounting plate at 90 degrees. The connecting piece of rivet diameter detection portion links to each other and fixes on first guide bar with the connecting block through middle contour sleeve. The other end of the first guide rod is provided with a hanging table, and the detection rod compressing block is provided with a through hole in sliding fit with the first guide rod and is pressed on the hanging table of the first guide rod through a first spring. The detection rod is pressed and fixed by the detection rod pressing block. After the diameter detection cylinder acts, the first guide rod is propped against the main functional block, namely the main functional block is the front limit of the diameter detection cylinder. At this time, the first spring detection rod abuts against the side face of the rivet, so that the cylinder is prevented from directly acting on the rivet, and the pressure injury is prevented. Thereby enabling detection of the rivet diameter by the first displacement sensor. The first product transferring part and the second product transferring part are arranged on the main mounting plate at a certain angle, and products on the first product transferring part and the second product transferring part jig can be taken and placed at the same position. The rivet identification part is fixed in an included angle formed by the first product conveying part and the second product conveying part. The rivet taking, placing and transferring parts are transversely arranged above the rivet identification part, the first product transferring part and the second product transferring part through the positioning vertical plate and the positioning plate.

The electromagnet is fixed on the second electromagnet fixing column. The inner side of the guide sleeve is provided with a guide inclined plane. After the electromagnet attracts the rivet, the second cylinder is used for taking and placing the rivet to return, the rivet is driven to rise into the guide sleeve 4-27, and the guided inclined plane is used for guiding and positioning the rivet.

Fig. 2, 3 and 6 show initial states of the rivet identification part; FIG. 4 shows the rivet being pulled to a neutral position; fig. 5 shows the rivet pulled to the rear position. At this time, both the rivet pull rod 1-17 driven by the rivet second cylinder 2-1 and the rivet middle stopper 1-21 driven by the rivet first cylinder 1-5 are in a forward pushing state, and the detection rod 1-36 driven by the diameter detection cylinder 1-24 is in a backward position. When the rivet in place sensor 1-16 senses that the rivet 1-2 is in place, the long rivet sensor 1-29 first detects whether the rivet 1-2 is acceptable. If the rivet is unqualified, the first pulling and riveting air cylinder 1-5 and the second pulling and riveting air cylinder 1-12 are simultaneously powered on, the rivet 1-2 is pulled to the rear position and then blown by the defective product blowing joint 1-19, and the rivet is blown into the defective product collecting box 1-23; if the rivet is qualified, the second air cylinder 1-12 is pulled to perform the power-on action, the rivet pull rod 1-17 is pulled to the middle position, at the moment, the diameter detection air cylinder 1-24 is subjected to the power-on action, and the first displacement sensor 1-32 and the short rivet sensor 1-33 judge whether the rivet 1-2 is qualified or not. If the rivet is unqualified, the first cylinder 1-5 is pulled to perform power-on action, and the rivet 1-2 is pulled to the rear position for isolation; if the rivet is qualified, waiting for the rivet to be taken and placed and sucked by the conveying part 4. Thus, the isolation of bad rivets and the automatic suction of good products are completed.

Fig. 8 is a state of two product transfer portions. First, the products 2-5 in the first transfer section 2 are outside, and the products 2-5 in the second transfer section 3 are inside. When the start button is pressed, the first transfer part 2 is driven by the first servo motor 2-1 to move to the first rivet placing position to wait for placing the rivet. Then the second transfer part 3 is driven by the second servo motor 3-1 to transfer to the outside for placing the product, when the first transfer part 2 sends out the product 2-5 after the product 2-5 finishes placing nails, the second transfer part 3 is driven by the second servo motor 3-1 to transfer the product to the inside, namely, the rivet is taken out and put under the transfer part, then the second transfer part sends out the product 2-5 finishing the nail placement, at the same time, the product which is sent out by the first transfer part and finishes the nail placement is taken away, the product which is not put is sent to the inside after being placed in the first transfer part and is sent under the rivet is taken out and put under the transfer part for placing nails, and the first transfer part and the second transfer part alternately convey nails, and circulate and reciprocate.

Fig. 9, 10, 11, and 12 are views showing the rivet picking and placing and transferring section 4. In addition, a second displacement sensor 4-18 is mounted to the mechanism to detect the height of the head of the rivet and thereby determine whether it is the desired rivet. The specific action flow is as follows: when the length and diameter of the rivet are judged to be qualified, the rivet taking and placing first cylinder 4-6 of the rivet taking and placing and transferring part 4 which stays right above the rivet 1-2 to be sucked is powered on firstly, and then the rivet taking and placing second cylinder 4-7 is powered on. After the second slide block 4-25 reaches the front limit 4-26 of the second cylinder for taking and placing the rivet, the second displacement sensor 4-18 judges whether the rivet 1-2 is qualified or not. If the rivet is unqualified, the first cylinder 4-6 and the second cylinder 4-7 return, then the first cylinder 1-5 is pulled to rivet to obtain electric action, and the rivet 1-2 is pulled to the rear position for isolation; if the rivet is qualified, the electromagnet 4-32 is electrified to suck the rivet 1-2, then the first air cylinder 4-6 and the second air cylinder 4-7 return, and the rivet is transferred to the first rivet placing position under the driving of the third servo motor 4-1. After the rivet is reached, the first air cylinder 4-6 and the second air cylinder 4-7 are electrified again to push the rivet into the product, and after the electromagnet 4-32 is powered off, the first air cylinder 4-6 and the second air cylinder 4-7 return again. The rivet taking and placing and transferring part 4 is driven to suck the rivet right above the rivet 1-2 to be sucked again. So reciprocating, automatic rivet releasing of rivets is realized.
