Return springs are respectively arranged on the outer sides of the first adjustment plate, the second adjustment plate, and the third adjustment plate.

[0017] The embodiment of the present invention also discloses a method for using an automatic rivet feeding device for pliers, including the following steps:

[0018] Feeding and screening: Put the rivets into the inside of the upper machine housing. The rivets move to the adjustment devices on both sides through the feeding ports on the left and right sides of the upper machine housing. The rivets enter the adjustment devices for position adjustment.

[0019] Transposition adjustment: Move the first adjustment plate towards the rivet to displace the rivet. Then move the second adjustment plate towards the rivet. The second adjustment plate pushes the rivet towards the third adjustment plate. After the rivet reaches the third adjustment plate, the third adjustment plate rotates to lift the rivet up and pour it to the right side at the same time.

[0020] Cache discharging: After the rivets are adjusted to the correct position, they enter the discharging channel and lead to the rotating disk through the discharging channel. After the rivets fall onto the rotating disk, the discharging speed and quantity of the rivets are controlled by the rotating disk. The large ends of the rivets that are separated from the selection disk face upward, and the small ends are within the discharging track. They lead to the conveying device through the discharging track and are conveyed to an external stamping machine by the conveying device for the assembly of the rivets and the pliers.

[0021] Furthermore, the embodiment of the present invention also discloses that after the feeding and screening step, it further includes: material distribution control. When the rivets enter the adjusting device, the material distribution device first conducts separation control on the rivets. After the rivets enter the material distribution device through the discharging port of the upper machine shell, control is carried out to keep the number of rivets in the material distribution device at one, and then the rivets are conveyed to the adjusting device through the material distribution device.

[0022] Furthermore, the embodiment of the present invention also discloses that after the cut-off control step, it further includes: gas diversion. During the rotation of the rotating drum, the waste and debris (abandoned neodymium iron boron) inside the rotating drum will generate dust when they impact during rotation. The dust flows through the through holes on the surface of the rotating drum to the outer periphery of the rotating drum and overflows inside the material conveying device. By starting the rotating motor of the filtering device, the blades provided on the rotating motor rotate to drain the dust in the material conveying device downward. After the dust enters the inner shell of the filter, it continuously moves downward and impacts the impacted baffle. The impacted baffle blocks the dust, and the blocked dust diffuses around the impacted baffle. When diffusing, the dust filters the dust impurities in the gas through the filter screen, and the gas flowing to the outer periphery of the inner shell of the filter forms clean air.

[0023] Furthermore, the embodiment of the present invention also discloses that during the feeding and screening, after the rivets enter the upper machine shell, the vibration device built in the upper machine shell vibrates the rivets to reduce the accumulation of rivets at the discharging port of the upper machine shell.

[0024] Further, the embodiment of the present invention also discloses that during the material distribution control, the first material distribution plate is first in an open state with the material distribution shell. When the first material distribution plate is in an open state with the material distribution shell, the control rod disengages from the blocking plate, and the blocking plate fits with the control rod. The blocking plate pops out towards the outside of the material distribution shell. When the blocking plate pops out and the first material distribution plate is in an open state, the second material distribution plate is in a closed state with the material distribution shell. At the same time, the rivet in the upper machine shell moves towards the inside of the material distribution shell through the discharge port. When the first rivet drops onto the second material distribution plate, the control motor connected to the swing plate drives the swing plate to rotate. The first material distribution plate moves towards the inside of the material distribution shell through the swing plate to form a closed state with the material distribution shell. At the same time, when the first material distribution plate is in a closed state, the control rod moves towards the blocking plate and presses it, pushing the blocking plate towards the inside of the material distribution shell. The blocking plate protrudes from the inner wall surface of the material distribution shell. When the first material distribution plate moves towards the inside of the material distribution shell, the second material distribution plate detaches from the material distribution shell to form an open state and conveys the first rivet into the adjustment device. At this time, the second rivet in the upper machine shell discharges into the material distribution shell and is controlled by the blocking plate to prevent it from directly falling into the adjustment device. After the swing plate is reset by the control motor, the first material distribution plate and the second material distribution plate return to their original positions, and the blocking plate also returns to its original position. At this time, the second rivet intercepted by the blocking plate falls onto the surface of the second material distribution plate. Then, the control motor drives the swing plate to swing reciprocally to form the opening and closing states of the first material distribution plate and the second material distribution plate, realizing the controlled blanking of the rivets.

[0025] Further, the embodiment of the present invention also discloses that during the transposition adjustment, since the rivets falling into the adjustment shell may be vertically falling, or the large round end is to the right, or the large round end is to the left. First, the adjustment wheel rotates to drive the first push plate to drive the first adjustment plate to move towards the inside of the adjustment shell. The first adjustment plate moves towards the rivet inside the adjustment shell. If the rivet is in a vertical state, the first adjustment plate pushes the rivet to the right to make it fall so that the large round end is to the left. Then, the second adjustment plate moves towards the rivet inside the adjustment shell. If the rivet is in the state where the large round end is to the left, then the second adjustment plate will not contact the small round end of the rivet. If the rivet is in the state where the large round end is to the right, then the second adjustment plate pushes the whole rivet to move to the left. The rivet moves to the third adjustment plate. The third adjustment plate moves towards the rivet inside the adjustment shell. If the rivet is in the state where the large round end is to the right, then the third adjustment plate will not contact the rivet. If the rivet is in the state where the large round end is to the left, then the hook-shaped end of the third adjustment plate will contact the small round end of the rivet and rotate the rivet with the large round end as the fulcrum to the right, so that the small round end of the rivet on the left rotates to the right to form a rotational adjustment. After the large round end of the rivet is on the left, it moves through the discharge port of the adjustment shell to the circulation channel of the lower machine shell for this buffered discharge.

[0026] The beneficial effects of the present invention are as follows: First, for the automatic rivet feeding device of the present invention, the position of the rivets is automatically adjusted, thereby improving the matching effect when the rivet and the pliers are used in combination with a stamping machine to prevent inaccurate matching between the rivet and the pliers. First, by putting the rivets into the upper casing, the upper casing vibrates the rivets, and at the same time, the vibration is used to adjust the position of the rivets and move the rivets to the discharge port of the upper casing to prevent all the rivets from accumulating at the discharge port of the upper casing, which affects the subsequent discharge of the rivets. Second, the number of rivets coming out of the upper casing is controlled by a material distribution device. When the rivets enter the material distribution shell, the rivets stay on the surface of the second material distribution plate. Then, the second material distribution plate separates from the material distribution shell, and the rivets fall into the adjustment shell. When the second material distribution plate separates from the material distribution shell, the first material distribution plate will fit with the material distribution shell to form a closed state. At this time, the rivets in the upper casing continue to be conveyed to the material distribution shell, and the subsequent rivets will be separated by the baffle plate. The baffle plate protrudes towards the inner wall of the material distribution shell to form a support, and the rivets are hung on the surface of the baffle plate to prevent excess rivets from staying on the surface of the first material distribution plate. If there are excess rivets staying on the surface of the first material distribution plate, then when the first material distribution plate and the material distribution shell are in an open state, multiple rivets will be put into the second material distribution plate and then into the adjustment shell, causing the adjustment shell to be blocked and unable to achieve the position adjustment of the rivets. Third, the position of the rivets passing through the material distribution device is changed by an adjustment device. The large circular end of the rivets is adjusted to the right by using the first adjustment plate, the second adjustment plate, and the third adjustment plate. Thus, when the rivets enter the rotating disk through the flow channel of the lower casing, the large circular end of the rivets is always at the upper end. Furthermore, when the subsequent rivets are used in combination with the pliers through a stamping machine, the assembly efficiency can be improved, and at the same time, the problems of slow efficiency and inaccurate docking during manual adjustment of the rivets can be reduced.

Return springs 206 are respectively arranged on the outer sides of the first adjustment plate 205, the second adjustment plate 203, and the third adjustment plate 207. The position of the rivet 50 passing through the material distribution device 30 is changed by the adjustment device 20. The large round end of the rivet 50 is adjusted to the right by using the first adjustment plate 205, the second adjustment plate 203, and the third adjustment plate 207. Thus, when the rivet 50 enters the rotating disk 108 through the flow channel of the lower housing 102, the large round end of the rivet 50 is always at the upper end. Furthermore, when the subsequent rivet 50 is cooperated with the stamping machine and the pliers, the assembly efficiency can be improved, and at the same time, the problems of slow efficiency and inaccurate docking during manual adjustment of the rivet 50 can be reduced.

[0069] Specifically, such as Figure 3 , 8, as shown in Figures 9, the automatic blanking device further includes: a material distribution device 30, which is arranged between the upper housing 101 and the adjustment device 20. The material distribution device 30 includes: a swing plate 301, a material distribution housing 302, a first material distribution plate 303, a second material distribution plate 304, a control rod 305, and a partition plate 306. The material distribution housing 302 is arranged in the middle of the upper housing 101 and the adjustment housing 201. The first material distribution plate 303 is inside the material distribution housing 302. The second material distribution plate 304 is inside the material distribution housing 302. The second material distribution plate 304 is located below the first material distribution plate 303. There is a gap between the first material distribution plate 303 and the second material distribution plate 304. The first material distribution plate 303 and the second material distribution plate 304 are connected by the swing plate 301. Both ends of the swing plate 301 are provided with movable extension plates. The first material distribution plate 303 and the second material distribution plate 304 are respectively connected to the extension plates of the swing plate 301. The swing plate 301 is inclined. The swing plate 301 is controlled by a control motor. When the first material distribution plate 303 and the material distribution housing 302 are closed, the second material distribution plate 304 and the material distribution housing 302 are open, and vice versa. Rectangular plates with inclined surfaces are arranged on the opposite sides of the first material distribution plate 303. The inclined rectangular plates of the first material distribution plate 303 cooperate with the control rod 305. The control rod 305 is arranged outside the material distribution housing 302. There are two control rods 305. One side of the control rod 305 is provided with an inclined rectangular plate adapted to the inclined rectangular plate of the first material distribution plate 303. The partition plate 306 can translate horizontally on the inner walls on both sides of the material distribution housing 302. A horizontal rectangular strip adapted to the partition plate 306 is arranged at the upper end of the control rod 305. When the first material distribution plate 303 and the material distribution housing 302 are closed, the control rod 305 squeezes the partition plate 306 to move inward into a convex shape. When the first material distribution plate 303 and the material distribution housing 302 are open, the control rod 305 releases the extrusion force on the partition plate 306, and the horizontal rectangular strip of the control rod 305 fits on the surface of the partition plate 306 to retract the partition plate 306.The number of rivets 50 coming out of the upper housing 101 is controlled by the material distribution device 30. When the rivets 50 enter the material distribution housing 302, the rivets 50 stay on the surface of the second material distribution plate 304. Then, the second material distribution plate 304 separates from the material distribution housing 302, and the rivets 50 fall into the adjustment housing 201. When the second material distribution plate 304 separates from the material distribution housing 302, the first material distribution plate 303 will fit with the material distribution housing 302 to form a closure. At this time, the rivets 50 in the upper housing 101 continue to be conveyed to the material distribution housing 302. The subsequent rivets 50 will be separated by the partition plate 306. The partition plate 306 protrudes towards the inner wall of the material distribution housing 302 to form a support, and the rivets 50 are hung on the surface of the partition plate 306 to prevent excess rivets 50 from staying on the surface of the first material distribution plate 303. If there are excess rivets 50 staying on the surface of the first material distribution plate 303, then when the first material distribution plate 303 and the material distribution housing 302 are in an open state, multiple rivets 50 will be put into the second material distribution plate 304 and then into the adjustment housing 201, causing the adjustment housing 201 to be blocked and the position adjustment of the rivets 50 cannot be achieved.

[0070] As Figure 10 , 11 shown, finally, a method for using an automatic feeding device for pliers rivets 50 is provided, including the following steps:

[0071] Feeding and screening: The rivets 50 are put into the interior of the upper housing 101. The rivets 50 move towards the adjustment devices 20 on both sides through the feeding ports on the left and right sides of the upper housing 101, and the rivets 50 enter the adjustment devices 20 for position adjustment.

[0072] Transposition adjustment: The first adjustment plate 205 moves towards the rivets 50 to displace the rivets 50. Then, the second adjustment plate 203 moves towards the rivets 50. The second adjustment plate 203 pushes the rivets 50 towards the third adjustment plate 207. After the rivets 50 reach the third adjustment plate 207, the third adjustment plate 207 rotates to lift the rivets 50 up and pour them to the right side at the same time.

[0073] Buffering and discharging: After the rivets 50 are adjusted to the correct positions, the rivets 50 enter the discharge channel and lead to the rotating disk 108 through the discharge channel. After the rivets 50 fall onto the rotating disk 108, the discharge speed and quantity of the rivets 50 are controlled by the rotating disk 108. The large end of the rivets 50 that are separated from the selection disk faces upwards and the small end is in the discharge track 109. The rivets 50 lead to the conveying device 40 through the discharge track 109 and are conveyed to an external stamping machine through the conveying device 40 for the assembly of the rivets 50 and the pliers.

[0074] Further, the embodiment of the present invention also discloses that after the feeding and screening step, it further includes: material distribution control. When the rivet 50 enters the adjusting device 20, the material distribution device 30 first performs separation control on the rivet 50. After the rivet 50 enters the material distribution device 30 through the discharge port of the upper housing 101, control is carried out to keep the number of rivets 50 in the material distribution device 30 at one, and then the rivet 50 is conveyed to the adjusting device 20 through the material distribution device 30.

[0075] Further, the embodiment of the present invention also discloses that after the current interruption control step, it further includes: gas diversion. During the rotation of the rotary drum, the waste and broken pieces of waste neodymium iron boron inside the rotary drum will generate dust when they collide and rotate. The dust flows through the through holes on the surface of the rotary drum to the outer periphery of the rotary drum and overflows inside the material conveying device. By starting the rotary motor of the filtering device, the blades provided on the rotary motor rotate to drain the dust in the material conveying device downward. After the dust enters the inner shell of the filter, it continuously moves downward and impacts the impacted baffle. The impacted baffle blocks the dust, and the blocked dust diffuses around the impacted baffle. When diffusing, the dust filters the dust impurities in the gas through the filter screen, and the gas flowing to the outer periphery of the inner shell of the filter forms clean air.

[0076] Further, the embodiment of the present invention also discloses that during feeding and screening, when the rivet 50 enters the upper housing 101, the vibration device built in the upper housing 101 vibrates the rivet 50 to reduce the accumulation of rivets 50 at the discharge port of the upper housing 101.

[0077] Further, the embodiment of the present invention also discloses that during the material distribution control, the first material distribution plate 303 is first in an open state with the material distribution shell 302. When the first material distribution plate 303 is in an open state with the material distribution shell 302, the control rod 305 disengages from the barrier plate 306, and the barrier plate 306 fits with the control rod 305. The barrier plate 306 pops out towards the outside of the material distribution shell 302. When the barrier plate 306 pops out and the first material distribution plate 303 is in an open state, the second material distribution plate 304 is in a closed state with the material distribution shell 302. At the same time, the rivet 50 in the upper housing 101 moves towards the inside of the material distribution shell 302 through the discharge port. When the first rivet 50 drops onto the second material distribution plate 304, the control motor connected to the swing plate 301 drives the swing plate 301 to rotate, and the first material distribution plate 303 moves towards the inside of the material distribution shell 302 through the swing plate 301 to form a closed state with the material distribution shell 302. At the same time, when the first material distribution plate 303 is in a closed state, the control rod 305 moves towards the barrier plate 306 and presses it, pushing the barrier towards the inside of the material distribution shell 302. The barrier plate 306 protrudes from the inner wall surface of the material distribution shell 302. When the first material distribution plate 303 moves towards the inside of the material distribution shell 302, the second material distribution plate 304 is separated from the material distribution shell 302 to form an open state, and the first rivet 50 is conveyed into the adjustment device 20. At this time, the second rivet 50 in the upper housing 101 is discharged into the material distribution shell 302 and is controlled by the barrier plate 306 to prevent it from directly falling into the adjustment device 20. After the swing plate 301 is reset by the control motor, the first material distribution plate 303 and the second material distribution plate 304 return to their original positions, and the barrier plate 306 also returns to its original position. At this time, the second rivet 50 intercepted by the barrier plate 306 falls onto the surface of the second material distribution plate 304. Then, the control motor drives the swing plate 301 to swing reciprocally to form the opening and closing states of the first material distribution plate 303 and the second material distribution plate 304, realizing the controlled blanking of the rivet 50.

[0078] Further, the embodiments of the present invention also disclose that during the transposition adjustment, since the rivets 50 falling into the adjustment housing 201 may be vertically inserted, or the large circular end may face right or left, first, the adjustment wheel 202 is rotated to drive the first adjustment plate 205 to move towards the inside of the adjustment housing 201 by means of the first push plate 2023. The first adjustment plate 205 moves towards the rivets 50 inside the adjustment housing 201. If the rivets 50 are in a vertical state, the first adjustment plate 205 pushes the rivets 50 to the right to make them fall, with the large circular end facing left. Then, the second adjustment plate 203 moves towards the rivets 50 inside the adjustment housing 201. If the large circular end of the rivets 50 faces left, the second adjustment plate 203 will not contact the small circular end of the rivets 50. If the large circular end of the rivets 50 faces right, the second adjustment plate 203 pushes the entire rivets 50 to move left. The rivets 50 move to the third adjustment plate 207. The third adjustment plate 207 moves towards the rivets 50 inside the adjustment housing 201. If the large circular end of the rivets 50 faces right, the third adjustment plate 207 will not contact the rivets 50. If the large circular end of the rivets 50 faces left, the hook-shaped end of the third adjustment plate 207 will contact the small circular end of the rivets 50 and simultaneously rotate the rivets 50 with the large circular end as the pivot point to the right, causing the small circular end of the rivets 50 on the left side to rotate to the right to form a rotational adjustment. After the large circular end of the rivets 50 is on the left side, they move through the discharge port of the adjustment housing 201 to the flow channel of the lower housing 102 for buffered discharge.

[0079] Although the above describes the illustrative specific embodiments of the present application for the convenience of those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all applications and creations using the concept of the present application are within the scope of protection.

At this time, the second rivet intercepted by the blocking plate falls onto the surface of the second feeding plate, and then the control motor drives the swing plate to swing reciprocally to form the opening and closing states of the first feeding plate and the second feeding plate to realize the controlled blanking of the rivet.

12. A method for using an automatic rivet feeding device for pliers according to claim 9, wherein, During the transposition adjustment, since the rivets falling into the adjustment housing may be in a vertical state, or the large circular end may face right or left, first rotate the adjustment wheel to drive the first adjustment plate to move into the adjustment housing by means of the first push plate. The first adjustment plate moves towards the rivets in the adjustment housing. If the rivet is in a vertical state, the first adjustment plate will push the rivet to the right to make it fall so that the large circular end faces left. Then, the second adjustment plate moves towards the rivets in the adjustment housing. If the large circular end of the rivet faces left, the second adjustment plate will not contact the small circular end of the rivet. If the large circular end of the rivet faces right, the second adjustment plate will push the whole rivet to move left. The rivet moves to the third adjustment plate. The third adjustment plate moves towards the rivets in the adjustment housing. If the large circular end of the rivet faces right, the third adjustment plate will not contact the rivet. If the large circular end of the rivet faces left, the hook-shaped end of the third adjustment plate will contact the small circular end of the rivet and at the same time rotate the rivet with the large circular end as the fulcrum to the right, so that the small circular end of the rivet on the left rotates to the right to form a rotational adjustment. After the large circular end of the rivet is on the left, it moves through the discharge port of the adjustment housing to the flow channel of the lower housing for the caching and discharging.
