These are the most common types of rivets used in computer motherboard production and installation. Generally, the production process requires the installation of corresponding riveting machines based on the process line's configuration needs. When the number of riveting machines is insufficient, appropriate purchases are made. This results in poor versatility of riveting machines, increasing production costs. Utility Model Content

Detailed Implementation

[0015] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0016] like Figures 1 to 3 As shown; a riveting machine feeding device for the lamination process of a computer motherboard includes a lifting frame 1, a rivet feeding device 2, a rivet positioning and ejection device 3, a return spring 4, and positioning posts 5. The rivet feeding device 2 is connected to the lifting frame 1. One end of the rivet positioning and ejection device 3 is hinged to the lifting frame 1, and the other end cooperates with the riveting machine. Two positioning posts 5 are connected to the lifting frame 1. One end of each of the two return springs 4 is sleeved on the corresponding positioning post 5, and the other end is connected to the rivet positioning and ejection device 3. The rivet feeding device 2 includes a power motor 21, a conical material box 22, a stirring shaft 23, a rivet ejector 24, a hopper 25, and a stirring mechanism. The stirring blade 26, the power motor 21 and the conical hopper 22 are mounted on the lifting frame 1. The stirring shaft 23 is movably connected inside the conical hopper 22 and one end passes through the side wall of the conical hopper 22 and is connected to the power rod of the power motor 21. The stirring blade 26 is set inside the conical hopper 22 and is connected to the stirring shaft 23. The hopper 25 is set at the top of the conical hopper 22, and a strip-shaped discharge port is set at the bottom of the hopper 25. The rivet ejector 24 is set on the strip-shaped discharge port. The rivet ejector 24 includes a side plate 27, a slide bar 28 and a rivet guide groove 29. The two side plates 27 are respectively connected to the conical hopper 22 on both sides of the strip-shaped discharge port. The slide bars 28 are slidably connected to the corresponding side plates 27, and the rivet guide grooves 29 are formed on the slide bars 28. The rivet positioning and guiding device 3 includes a left guiding bar 31, a right guiding bar 32, and an adjuster 33. The left guiding bar 31 and the right guiding bar 32 are symmetrically arranged, and several adjusters 33 are connected between the left guiding bar 31 and the right guiding bar 32. One end of the left guiding bar 31 and the right guiding bar 32 is symmetrically connected to a hinge device 34, which is connected to the lifting frame 1. The left guiding bar 31 and the right guiding bar 32 are provided with rivet sliding grooves. The hinge device 34 includes a rotating shaft 35 and a stabilizing connecting block 36. The stabilizing connecting block 36 is connected to the lifting frame 1. One end of the rotating shaft 35 passes through the stabilizing connecting block 36 and is connected to the corresponding left guide bar 31 or right guide bar 32. A positioning bullseye is installed at the end of the left guide bar 31 or right guide bar 32 away from the hinge device 34. The adjuster 33 includes a connecting block 37, an adjusting rod 38, a spring 39, and an adjusting nut 310. The two connecting blocks 37 are respectively connected to the left guide bar 31 and the right guide bar 32. Both ends of the adjusting rod 38 pass through the corresponding connecting blocks 37 and are connected to the adjusting nut 310. The spring 39 is sleeved on the adjusting rod 38 and is located between the two connecting blocks 37.

[0017] When the feeding device supplies rivets, it guides the rivets into the conical hopper 22 through the hopper 25. Then, the power motor 21 is turned on, driving the stirring shaft 23 to rotate. The stirring shaft 23 drives the stirring blades 26 to stir the rivets in the conical hopper 22, causing the end of the rivet to insert between the two sliding strips 28. At the same time, the rivet head is hooked in the rivet guide groove 29 of the sliding strip 28. Then, the rivet slides along the taper of the conical hopper 22 into the rivet slide groove, and moves along the rivet slide groove to the head of the riveting machine. At the same time, the rivet is positioned by the bullseye. When adjusting the rivet ejector 24, the sliding strip 28 of the corresponding width is replaced as needed. When adjusting the adjuster 33, the left ejector strip 31 and the right ejector strip 31 are adjusted by rotating the adjusting nut 310. 2. Approaching or moving away from the riveting machine head allows for the corresponding rivet feeding; when the riveting machine head descends, it applies pressure to the left guide bar 31 and the right guide bar 32, causing the return spring 4 to contract. The ends of the left guide bar 31 and the right guide bar 32 rotate along the hinge, ensuring that the ends of the left guide bar 31 and the right guide bar 32 do not affect the descent of the riveting machine head for riveting. When the riveting machine head descends, it inserts into the rivets at the ends of the left guide bar 31 and the right guide bar 32, and drives the rivets to descend quickly for riveting. When the return spring 4 drives the left guide bar 31 and the right guide bar 32 to reset, the lifting frame 1 limits the lifting height of one end of the left guide bar 31 and the right guide bar 32 to ensure that the ends of the left guide bar 31 and the right guide bar 32 are aligned with the position of the riveting machine head.
