Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The utility model discloses a first loading board 1, fix rotating member 2 on first loading board 1, the gas blow pipe 3 of intercommunication rotating member 2, the ejector pin 4 of vertical direction motion and inside ejection of compact 5 that is equipped with perpendicular latus rectum 50. The ejector rod 4 is driven 6 by a first driving part fixed on the first bearing plate 1, and the first driving part 6 is preferably an air cylinder.

The rotating member 2 includes an upper cover plate 21, a lower cover plate 22, and a turntable 20 disposed between the upper and lower cover plates and connected to the rotating member, wherein the turntable 20 is rotatable around a rotation axis relative to the upper and lower cover plates. The rotary table 20 is provided with a rivet accommodating hole, the upper cover plate 21 and the lower cover plate 22 are respectively and correspondingly provided with a through hole for the mandril 4 to vertically pass through and further extend into the vertical drift diameter 50 of the discharging part, and the other end of the upper cover plate 21 is also provided with a through hole connected with the discharging hole of the gas blowing pipe 3. The mandril 4 and the air blowing pipe 3 are both positioned above the rotating piece 2 and are respectively positioned at two opposite sides of the rotating piece 2. Specifically, the rivet receiving hole is a through hole in which the rivet can be rotatably transferred since the lower surface of the turntable 20 is in contact with the upper surface of the lower cover plate 22. Of course, the structure of the rotating member 2 is not limited to the structure given in the present embodiment, for example, it may also be a housing with a hollow inside, and the rotating disc is disposed inside the housing and can rotate relative to the housing; or the rotating disc can be replaced by a component which can rotate around the rotating shaft and is provided with a rivet containing hole and the like.

When the rivet holding hole works, the rivet holding hole is firstly butted with a discharge hole of the air blowing pipe 3. After the rivet vertically enters the air blowing pipe 3 and then falls into the rivet accommodating hole under the self gravity, the rotary table 20 rotates 180 degrees to convey the rivet to the position corresponding to the through hole of the ejector rod 4, a path is formed between the rivet and the through hole of the upper cover plate and the rivet and the through hole of the lower cover plate, and the rivet can automatically and vertically fall into the feeding and discharging part 5. In particular, the end of the vertical bore 50 of the discharge opening is conically tapered so that the rivet 14 cannot fall completely out of the discharge opening under its own weight to remain at the end of the vertical bore, i.e., the rivet cap is in interference fit with the end of the vertical bore. At this time, the rivet 14 in the vertical path can be vertically ejected into the rivet reserving hole of the product after the ejector pin vertically passes through the path of the rotating member downwards.

In order to further ensure the vertical transmission of the rivets in the whole feeding process, a rivet proximity sensor 7 is arranged at the feed inlet of the air blowing pipe, and an optical fiber sensor 8 is arranged on a lower cover plate of the rotating part corresponding to the discharge outlet of the air blowing pipe. A pair of clamping jaws 10 which are movable through an air cylinder are further arranged below the discharging piece, when the rivet 14 hovers at the tail end of the vertical drift diameter 50, the clamping jaws 10 clamp the rivet 14 body for positioning, and the rivet placing effect of the ejector rod 4 is assisted. The clamping jaw 10 is fixed on the first loading plate 1.

The discharging piece is also provided with an air blowing joint 9 communicated with the vertical drift diameter 50, and the rivet can be assisted to fall in the vertical drift diameter 50 through air blowing, so that the feeding speed is accelerated.

Meanwhile, in order to improve the automation efficiency of the whole mechanism, two rivet receiving holes which are distributed oppositely in the radial direction may be formed on the rotating disc 20.

Because the gas blow pipe 3 adopts transparent plastic material, consequently can go out at the discharge gate and can set up metal lantern ring 13 in order to strengthen the fastness. The air blowing pipe 3 is vertically arranged.
