[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Please see Figures 1 to 4 This utility model provides an embodiment of a rivet feeding mechanism, comprising a vibratory feeder 10, a positioning component 20, and a positioning fixture 30 that cooperate with each other. The vibratory feeder 10 is used to vibrate and feed rivets, each rivet having a hole in its center. The positioning component 20 includes a positioning platform 21 and a rear baffle 22 and a front baffle 23 disposed on the positioning platform 21. The front baffle 23 is slidably connected to the positioning platform 21. The rear baffle 22 has several limiting grooves 24 on the side near the front baffle 23, and the front baffle 23 has several stop bars 25 on the side near the rear baffle 11. The positions and numbers of the limiting grooves 24 and the stop bars 25 correspond. The vibratory feeder 10 is connected to a material channel 11, the outlet of which abuts against the rear baffle 22, and the outlet of the material channel 11 is flush with the height of the limiting grooves 24. The vibratory feeder 10 vibrates the rivets to the corresponding limiting grooves 24. Inside the 4, the front baffle 23 can slide closer to or further away from the rear baffle 22. The positioning fixture 30 is provided with several through holes 31, and is equipped with ejector pins 32 and limiting protrusions 33. When the product is placed on the limiting protrusions 33, the ejector pins 32 pass through the through holes 31 from top to bottom and are inserted into the holes in the product to achieve product positioning. When the front baffle 23 approaches the rear baffle 22, the corresponding limiting grooves 24 and the stop bars 25 approach each other to form a limiting structure. Each limiting structure can hold a positioning rivet for rivet positioning. Several limiting structures and several through holes 31 are aligned from top to bottom. Then the ejector pins 32 move upward and insert the rivet. Finally, the front baffle 23 moves away from the rear baffle 22, and the rivet slides down along the ejector pins 32 to the holes in the product. Multiple holes can be used for material feeding, achieving efficient positioning and feeding and improving production efficiency.

[0022] Furthermore, the bottom of the positioning fixture 30 is movably connected to a movable seat 34, and several ejector pins 32 are mounted on the movable seat 34. The ejector pins 32 move up and down with the movable seat 34. The positioning assembly 20 also includes a lifting module 26 and a push plate 27 disposed at the movable end of the lifting module 26. The push plate 27 moves upward and can abut against the movable seat 34. The lifting module 26 is used to lift the movable seat 27 to realize the upward movement of the ejector pins 32. After the lifting module 26 is reset, the movable seat 27 and the ejector pins 32 fall downward under the action of gravity.

[0023] Furthermore, a first propulsion cylinder 28 is provided on the positioning platform 21, and the movable end of the first propulsion cylinder 28 is connected to the front baffle 23.

[0024] Furthermore, the rear baffle 22 is slidably connected to the positioning platform 21, and the transmission direction of the rear baffle 22 is perpendicular to the transmission direction of the front baffle 23. The positioning platform 21 is provided with a second propulsion cylinder 29, which is connected to the rear baffle 22. This structure can connect a material channel 11 through the vibrating plate 10 and continuously feed material. Since the outlet of the material channel 11 is in contact with the rear baffle 22, no material will fall. When the rear baffle 22 moves, the material channel 11 outlet is aligned with the limiting groove 24, and the rivet is fed into the limiting groove 24.

[0025] Furthermore, the gear bar 25 has a locking groove 251 on the side near the limiting groove, and the structure of the locking groove 251 is adapted to the shape of the rivet, and it clamps with the limiting groove 24 to achieve a better positioning effect.

[0026] Furthermore, the positioning fixture 30 can be mounted on the transmission mechanism (not shown) to improve feeding efficiency by switching products without rivets; the transmission mechanism can be a turntable.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
