[0002] Pull rivets, also known as core-pulling rivets, are a type of fastener used for single-sided riveting, but they must be riveted using a special tool - a rivet gun (manual, electric, or pneumatic). Due to the small size of pull rivets, the continuous supply of a large number of pull rivets requires accuracy and reliability to avoid affecting subsequent processing. In traditional operations, manual feeding and locking of pull rivets are performed manually. This not only takes up a lot of manpower, reduces work efficiency, causes waste of resources and increases costs, but is also prone to accidents such as wrong materials, falling materials, and empty materials.

[0003] In order to solve the above problems, for example, Chinese patent document 202220642239.9 discloses an automatic nail changing device, including a nail gun, a magazine and a base plate, wherein the base plate is fixedly connected to a bracket, a gun seat fixing rod is rotatably provided on one side of the bracket close to the tail of the nail gun grip, the bracket is detachably connected to the gun handle of the nail gun through the gun seat fixing rod, a magazine fixing spring is provided on the inner groove wall of the bracket close to the gun seat fixing rod, a bullet pushing guide sleeve pressure plate and a bullet pushing block guide sleeve are provided on the clamp plate close to the gun body of the nail gun, and the bracket is detachably connected to the gun handle of the nail gun through the gun seat fixing rod.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Embodiment 1

[0030] like Figures 1 to 4 As shown, the fully automatic rivet screw supply equipment includes a base frame 1 with a blanking plate 2, a clip 4 is erected on the blanking plate 2, a curved trajectory 4a is arranged in the clip 4, the top end of the curved trajectory 4a is unobstructed to form a feed port, the bottom end of the curved trajectory 4a is unobstructed to form a discharge port, the blanking plate 2 is provided with a blanking port connected to the discharge port, a pushing piece 10 is slidably arranged in the blanking plate 2, a material embedding groove is arranged on the pushing piece 10, and the pushing piece 10 is connected by a pushing driver; a cutting piece 5 is slidably arranged at the bottom of the clip 4, and the cutting end of the cutting piece 5 can cut off the discharge port, a cutting driver is arranged on the base frame 1, and the cutting driver is connected to the cutting piece 5 through a transmission member 7.

[0031] like Figure 1 As shown, a frame 3 is erected on the blanking plate 2, and the frame 3 includes two half-frames that are symmetrical on both sides. The two half-frames are surrounded to form a blanking station, and the clip 4 is inserted into the frame 3 to form a positioning assembly. The frame 3 can not only define the area of ​​the blanking station, but also provide a support structure for the installation of the clip 4.

[0032] like Figure 2As shown, the curved trajectory 4a is formed by bending back and forth in the horizontal direction and extending in the longitudinal direction. The curved trajectory 4a includes a plurality of left convex arc paths and a plurality of right convex arc paths. The left convex arc paths and the right convex arc paths are connected by transition inclined paths. The trajectory with a reciprocating bending structure increases the number of pull rivet screws than the straight trajectory. At the same time, the use of arc and inclined trajectory shapes facilitates the smooth feeding of the pull rivet screws to avoid jamming.

[0033] Profiling grooves are arranged along the track of the curved trajectory 4a, and the profiling grooves include deep grooves and shallow grooves arranged side by side, and the deep grooves and shallow grooves are connected by step surfaces. Profiling grooves matching the external structure of the rivet screws are designed, so that a large number of rivet screws are placed in the curved trajectory 4a to form a chiseled match, forming a continuous and neat arrangement, which is conducive to smooth and effective material feeding needs and avoids jamming or vacancies.

[0034] like Figure 3 As shown, a transverse chute is provided at the bottom of the magazine 4, one end of which is connected to the discharge port of the curved trajectory 4a, and the upper part of the transverse chute is widened to form a limiting groove, the length of which is less than the length of the transverse chute.

[0035] The cutting piece 5 includes a main rod, which is embedded in the transverse slide groove to form a reciprocating sliding connection. A wedge-shaped tip is set at one end of the main rod to form a cutting end. A limit block is convexly set on the top of the main rod. The limit block is located in the length area of ​​the limit groove. A transmission support rod 5a is vertically fixed in the middle of the main rod.

[0036] The main rod moves forward and backward in the transverse slot, driving the limit block to move forward and backward in the limit slot. When the limit block abuts against the front end of the limit slot, the main rod moves forward to the limit position. When the limit block abuts against the rear end of the limit slot, the main rod moves backward to the limit position, which plays a role in limiting the lateral movement of the main rod. The main rod is inserted between the upper and lower adjacent rivet screws through the wedge-shaped tip, and the upper rivet screw is slightly lifted by the inclined surface of the wedge-shaped tip and trapped in the curved trajectory 4a.

[0037] The material cutting driver is a telescopic cylinder 6, and the transmission member 7 includes a transmission plate, a U-shaped support plate 7a and a clamping frame 7b are erected on the transmission plate, a guide groove is recessed on the top surface of the blanking plate 2, and the transmission plate is embedded in the guide groove to form a horizontal guide sliding connection. The telescopic rod of the telescopic cylinder 6 extends into the U-shaped support plate 7a and is locked and fixed by a nut, and the transmission support rod 5a extends into the clamping frame 7b to form a clamping fixation. The telescopic cylinder 6 drives the telescopic rod to extend and retract, and synchronously drives the transmission member 7 to slide back and forth horizontally in the guide groove. Through the connection between the clamping frame 7b and the transmission support rod 5a, it synchronously drives the main rod to move forward and backward in the horizontal slide groove to realize the material cutting and discharging actions.

[0038] like Figure 4As shown, the push drive is a telescopic cylinder 28, which is fixed on the base frame 1 below the blanking plate 2, and the telescopic rod 2 of the telescopic cylinder 28 is fixedly connected to one end of the push piece 10 through the connecting plate 9. The telescopic cylinder 28 drives the telescopic rod 2 to move telescopically, and synchronously drives the push piece 10 to slide back and forth horizontally to perform a cyclic push action.

[0039] The material pusher 10 is a jig plate, and the material embedding groove is a profiled groove opened on the jig plate. A clamping seat 11 is fixed on one side of the base frame 1, and a material extraction positioning groove is set on the clamping seat 11. The jig plate is shifted to the top of the clamping seat 11, so that the profiled groove and the material extraction positioning groove are directly opposite and connected. The rivet screw is embedded in the profiled groove, and the rivet screw is pushed to the position of the clamping seat 11 through the jig plate, and the rivet screw falls into the material extraction positioning groove. It plays a role in limiting the rivet screw during the movement of the jig plate.

[0040] The operation process of the fully automatic pull rivet screw supply equipment is:

[0041] A number of rivet screws are placed from the feed port into the curved trajectory 4a to form a curved trajectory arrangement. Under the action of gravity, the rivet screws are accumulated above the discharge port in sequence. At this time, the cutting end of the cutting piece 5 blocks the discharge port, preventing the rivet screws from falling.

[0042] The cutting driver drives the transmission member 7 to move horizontally backward, and synchronously drives the cutting member 5 to move backward, so that the cutting end is withdrawn to make the discharge port unobstructed, and the lowest rivet screw falls, passes through the discharge port of the discharge plate 2 and falls into the embedding groove of the pushing member 10. The cutting driver drives the transmission member 7 to move horizontally forward, and synchronously drives the cutting member 5 to move forward, so that the cutting end blocks the discharge port again.

[0043] The push drive pushes the push piece 10 forward, so that the rivet screw in the embedding groove reaches the top of the clamping seat 11, and the rivet screw falls into the material picking positioning groove of the clamping seat 11 to wait for the pneumatic finger to pick up the material, and the push drive pulls the push piece 10 to move backward and reset.
