[0031] As Figures 1 to 4 shown, an automatic feeding device for PCB riveting includes a material separating component 1, a second track 5 and a frame 2. The discharging end of the second track 5 is connected to the material separating component 1.

[0032] As Figures 4 to 7 shown, the material separating component 1 includes a fixing frame 101. A vertical frame 102 is connected to the top of the fixing frame 101. A module 103 is fixedly connected to the top of the vertical frame 102. A receiving groove is provided on the module 103. A rivet 14 is arranged inside the receiving groove. A photoelectric sensor is also fixedly connected to the module 103 to detect the state of the rivet 14 through the photoelectric sensor;

[0033] A first cylinder 104 is fixedly connected to the fixing frame 101. The output end of the first cylinder 104 is fixedly connected to a push rod 105. The top of the push rod 105 is in contact with the bottom of the rivet 14;

[0034] An installation frame 106 is fixedly connected to one side of the fixing frame 101. A second cylinder 107 is fixedly connected to the top of the installation frame 106. The output end of the second cylinder 107 is fixedly connected to a baffle 108. There is a notch on one side of the tail end of the second track 5. The baffle 108 is located in the notch. When it is detected that the head of the rivet 14 is downward, the second cylinder 107 performs a retraction action to remove the baffle 108 from the notch of the second track 5. The first cylinder 104 operates to push the rivet 14 upward. When moving to the notch of the second track 5, if the head of the rivet 14 is downward, the core rod part will tilt due to gravity and fall out from the notch, realizing the screening of the rivet 14, so that only the qualified rivets 14 enter the riveting process, thereby improving the quality and reliability of riveting.

[0035] As Figures 4 to 7 shown, a receiving pipe 109 is fixedly connected to the bottom of the tail end of the second track 5. There is a receiving port between the inner side of the receiving pipe 109 and the outer side of the second track 5. The rivets falling out from the notch of the second track 5 will enter the receiving port and fall into the receiving pipe 109 through the receiving port, facilitating the collection of unqualified rivets 14 and avoiding the scattered distribution of the rivets 14, causing chaos or damage to the equipment.

[0036] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, a third cylinder 110 is fixedly connected to the outside of the fixing frame 101. The output end of the third cylinder 110 is fixedly connected to the vertical frame 102. The bottom of the vertical frame 102 is fixedly connected with a slider 111. The top of the fixing frame 101 is fixedly connected with a slide rail 112. The slider 111 is slidably connected to the slide rail 112. The telescopic movement of the third cylinder 110 will drive the vertical frame 102 to move horizontally. The slider 111 slides on the slide rail 112, and the distance between the module 103 and the second track 5 can be adjusted, so that the rivets 14 can be accurately conveyed into the receiving groove of the module 103.

[0037] As Figure 1 , Figure 2 and Figure 3 shown in the figure, a vibrating bowl 3 is fixedly connected to the top of the machine frame 2. The discharge end of the vibrating bowl 3 is fixedly connected with a first track 4. The second track 5 is fixedly connected to the discharge end of the first track 4. A first linear vibrator 6 is fixedly connected to the bottom of the first track 4. The bottom of the first linear vibrator 6 is fixedly connected with a first support 7. The bottom of the first support 7 is fixedly connected to the bottom plate of the vibrating bowl 3. A support plate 8 is fixedly connected to the bottom plate of the vibrating bowl 3. The fixing frame 101 is fixedly connected to one end of the top of the support plate 8 away from the vibrating bowl 3. A second support 9 is fixedly connected to the top of the support plate 8. The top of the second support 9 is fixedly connected with a second linear vibrator 10. The top of the second linear vibrator 10 is fixedly connected to the bottom of the second track 5. The vibrating bowl 3 can automatically arrange the disordered rivets 14 in an orderly manner and convey them to the discharge end. The rivets 14 are conveyed into the receiving groove of the module 103 through the first track 4 and the second track 5. The first linear vibrator 6 can ensure the smooth movement of the rivets 14 on the first track 4. The second linear vibrator 10 can ensure the smooth movement of the rivets 14 on the second track 5, avoiding the situation of jamming of the rivets 14 during the conveying process and improving the conveying efficiency.

[0038] As Figure 1 , Figure 2 and Figure 3 shown in the figure, a support plate 11 is fixedly connected to the top of the machine frame 2. The top of the support plate 11 is fixedly connected to the bottom of the first track 4. The support plate 11 provides support for the bottom of the first track 4, which can effectively disperse and bear the weight of the first track 4 and the rivets 14 thereon, enhancing the bearing capacity of the first track 4.

[0039] As Figure 1 shown in the figure, a protective cover 12 is fixedly connected to the top of the machine frame 2. The top of the protective cover 12 is hinged with a top sealing plate 13. The setting of the protective cover 12 provides a protective barrier for the vibrating bowl 3, preventing external personnel or objects from accidentally contacting the operating vibrating bowl 3 and improving safety.

[0040] Working principle: The vibrating bowl 3 can automatically arrange the disordered rivets 14 in an orderly manner and convey them to the discharge end. The rivets 14 are conveyed to the receiving groove of the module 103 through the first track 4 and the second track 5;

[0041] When it is detected that the head of the rivet 14 is downward, the second cylinder 107 contracts, removing the baffle 108 from the notch of the second track 5. The first cylinder 104 operates to push the rivet 14 upward. When it moves to the notch of the second track 5, if the head of the rivet 14 is downward, its shank part will tilt due to gravity and fall out from the notch;

[0042] The rivets that fall out from the notch of the second track 5 will enter the receiving port and fall into the receiving pipe 109 through the receiving port.
