Abstract
Description
Technical Field
[0001] This application relates to the field of riveting equipment technology, and in particular to a mechanical nail feeding station. Background Technology
[0002] In automated automotive production lines, to improve the continuity and efficiency of the riveting process, riveting systems are typically equipped with rivet storage bins with multi-rivet storage capabilities, as well as rivet feeding boxes, rivet feeding mechanisms, rivet receiving mechanisms, robotic arms, and rivet guns. In the riveting system, the rivet feeding mechanism is connected to the rivet feeding box, while the rivet receiving mechanism, storage bin, and rivet gun are all integrated into the end of the robotic arm. The storage bin has a U-shaped layout, with its top two ends serving as the inlet and outlet, respectively connecting to the rivet receiving mechanism and the rivet gun, forming a continuous rivet delivery path.
[0003] During riveting operations, rivets are stored sequentially in the rivet receiving mechanism and the storage bin. As rivets are continuously supplied to the rivet gun, the rivet receiving mechanism continuously replenishes the storage bin. When the rivets in the rivet receiving mechanism are exhausted, only rivets remain in the U-shaped storage bin. At this point, due to the characteristics of the U-shaped structure, the remaining rivets accumulate in the arc-shaped area at the bottom of the bin under gravity, making it difficult for them to be smoothly transported to the discharge end by their own weight, resulting in poor rivet supply. This situation causes the system's automatic rivet replenishment process to be triggered before the rivets are completely exhausted, affecting the continuous operation capability of the riveting system and reducing overall work efficiency. Summary of the Invention
[0004] In order to improve the continuous operation capability and overall work efficiency of the riveting system, this application provides a mechanical nail feeding station.
[0005] The mechanical nail feeding station provided in this application adopts the following technical solution: A mechanical nail feeding station includes a nail feeding mechanism, a nail receiving mechanism, and a storage bin. The nail receiving mechanism includes a first fixed base and two nail receiving tracks. The first fixed base is mounted on a robotic arm, and the two nail receiving tracks are mounted on the first fixed base. A feeding seat is located at the bottom end of each of the two nail receiving tracks. Two feeding chutes are formed within the feeding seat, and the bottom ends of the two nail receiving tracks are respectively inserted into the two feeding chutes. A feeding block is slidably disposed within the feeding seat, and a feeding port is formed within the feeding block. A first driving component is mounted on the feeding seat, and a discharge chute is formed within the feeding seat. The feeding end of the storage bin is inserted into the discharge chute. The first driving component pushes the feeding block to reciprocate, causing the feeding port to sequentially connect with the discharge chute and the two feeding chutes. A first air supply channel is formed within the feeding seat, and the first air supply channel is connected to the discharge chute through the feeding port.
[0006] By adopting the above technical solution, rivets are stored in a storage bin and two rivet-receiving tracks. The first driving component drives the feeding block to reciprocate horizontally. When the feeding port moves to connect with the first feeding chute, a rivet at the bottom of the feeding chute enters the feeding port. When the feeding port moves to connect with the discharge chute, the rivet in the feeding port enters the storage bin through the discharge chute. During the continuous reciprocating horizontal movement of the feeding block, the rivets in the two rivet-receiving tracks can be sequentially transported to the storage bin. When all the rivets in the rivet-receiving tracks are sent into the storage bin, the first air supply channel blows gas into the discharge chute through the feeding port. After the gas enters the storage bin, it blows the rivets at the bottom of the storage bin toward the rivet gun at the discharge end, so that all the rivets in the storage bin can be fed into the rivet gun, thereby improving the continuous operation capability of the riveting system and improving the overall work efficiency.
[0007] Preferably, a pin holder is fixedly installed at the top of the two pin-connecting rails, and two second air supply channels are opened in the pin holder, which are respectively connected to the top of the two pin-connecting rails.
[0008] By adopting the above technical solution, when the rivet at the bottom of the feeding chute enters the discharge port, the second air supply channel blows gas into the rivet receiving track. The gas pushes the rivet to slide in the rivet receiving track and the feeding chute, thereby facilitating the smooth entry of the rivet into the discharge port.
[0009] Preferably, the nail feeding mechanism includes a second fixed base and a nail feeding track. The second fixed base is fixedly mounted on the nail feeding box, and the nail feeding track is fixedly mounted on the second fixed base. A second sealing plate is rotatably mounted at the bottom of the nail feeding track, and the second sealing plate rotatably closes the nail feeding track. A first sealing plate is rotatably mounted at the top of the nail receiving seat. Pull plates are provided on opposite sides of the nail receiving seat, and elastic elements are provided on both pull plates. The ends of the two elastic elements are respectively connected to the two sides of the first sealing plate, causing the first sealing plate to rotate and close the nail receiving track. A push block is fixedly mounted on the second sealing plate, and a second trigger wheel is rotatably mounted inside the nail receiving seat. The second trigger wheel moves to contact the push block and drives the second sealing plate to rotate, opening the nail feeding track. A first trigger wheel is rotatably mounted on the first sealing plate, and a push rod is fixedly mounted at the bottom of the second fixed base. The first trigger wheel moves to contact the push rod and drives the first sealing plate to rotate, opening the nail receiving track.
[0010] By adopting the above technical solution, when the nail receiving mechanism and the nail supply mechanism are not connected, the second sealing plate rotates under the action of gravity to close the nail supply track, and the elastic element pulls the first sealing plate to rotate and close the nail receiving track; when the nail receiving mechanism and the nail supply mechanism begin to connect, the robotic arm drives the nail receiving mechanism to move upward and approach the nail supply mechanism, the second trigger wheel moves to contact the push block and drives the second sealing plate to rotate to open the nail supply track, the first trigger wheel moves to contact the push rod and drives the first sealing plate to rotate to open the nail receiving track, and after the nail supply track and the nail receiving track are connected, the nail supply operation can begin.
[0011] Preferably, a guide seat is fixedly provided on the first fixed seat, and two guide holes are opened in the guide seat. Two guide rods are fixedly provided at the bottom of the second fixed seat, and the two guide rods are slidably inserted into the two guide holes respectively.
[0012] By adopting the above technical solution, when the nail feeding mechanism and the nail receiving mechanism begin to dock, the nail receiving mechanism drives the guide seat to move towards the guide rod, and the two guide rods are inserted into the two guide holes, thereby guiding the docking of the nail feeding mechanism and the nail receiving mechanism, making the docking more accurate.
[0013] Preferably, the material feeding seat has chamfers on both sides of the first air supply channel, and an air supply groove is formed between the two chamfers and the material feeding block. When the material feeding port is connected to the discharge chute, the two air supply grooves are connected to the discharge chute and the two feeding chutes.
[0014] By adopting the above technical solution, after all the rivets in the rivet-connecting track are fed into the storage bin, the first air supply channel blows gas into the discharge chute through the discharge port, and the second air supply channel blows gas into the feed chute through the rivet-connecting track. The gas in the two feed chutes enters the discharge chute through the air supply channel, making the gas flow in the discharge chute larger, which makes it easier to blow up the rivets at the bottom of the storage bin.
[0015] Preferably, the storage bin has a first chute and a second chute that are interconnected. The width of the first chute is greater than the width of the second chute. The head of the rivet slides in the first chute, and the body of the rivet slides in the second chute. The storage bin is slidably mounted on a slide plate located in the first chute. The storage bin is equipped with an elastic winding assembly for pulling the slide plate toward the feed end of the storage bin. A push plate is rotatably mounted on the slide plate. The storage bin is equipped with a drive assembly for pushing the push plate to rotate into the second chute and pulling the push plate to rotate into the first chute.
[0016] By adopting the above technical solution, when the rivets are stored in the storage bin and the two rivet receiving tracks, the drive component pulls the push plate to rotate and enter the first slide groove. The push plate and the slide plate are located in the first slide groove and will not interfere with the movement of the rivets. After all the rivets in the receiving tracks are fed into the storage bin, the drive component pushes the rotating plate to rotate and enter the second slide groove. The gas blown out by the first air supply channel enters the first and second slide grooves through the discharge slide groove. The gas pushes the push plate and the slide plate to move in the first and second slide grooves. The push plate pushes the rivets to move in the first and second slide grooves, thereby facilitating the feeding of all the rivets into the rivet gun. After the rivets are used up, the first air supply channel stops supplying air, the elastic authorization component pulls the slide plate and the push plate to move and reset, and the drive component pulls the push plate to rotate and reset to the first slide groove, thereby facilitating the re-entry of the rivets into the storage bin.
[0017] Preferably, the driving assembly includes a driving frame, a second driving member, a slider, a driving rod, a driving block, and a driving frame. The driving frame is fixedly mounted on the storage bin, the slider is slidably mounted inside the driving frame, the second driving member is mounted on the driving frame and used to push the slider to reciprocate, the driving rod is fixedly mounted on the slider, the end of the driving rod slides through the storage bin and extends into the first groove, the driving block is fixedly mounted on the end of the driving rod, the driving frame is fixedly mounted on the push plate, the driving block is slidably mounted on the driving frame, and the end of the driving frame is open.
[0018] By adopting the above technical solution, the second driving component drives the slider to move on the driving frame, the slider drives the driving rod to move, and the driving rod drives the driving block to move within the driving frame. When it is necessary to rotate the push plate into the second slide groove, the driving block moves towards the opening direction at the end of the driving frame. During the movement of the driving block, the push plate is rotated and opened by the driving frame. When the driving block slides out of the driving frame from the opening, the push plate rotates to the maximum angle and enters the second slide groove. At this time, the gas can push the push plate to slide within the second slide groove. After the elastic winding assembly pulls the push plate to move and reset, the driving block moves in the direction and moves from the opening end of the driving frame into the driving frame. During the movement of the driving block, the push plate can be rotated by the driving frame, so that the push plate can rotate and reset into the first slide groove.
[0019] Preferably, the elastic winding assembly includes a winding box, an elastic winding member, and a pull rope. The winding box is fixedly mounted on the storage bin, and the elastic winding member is disposed inside the winding box. One end of the elastic winding member is fixedly connected to the middle of the winding box, and the other end is connected to the pull rope. The end of the pull rope away from the elastic winding member passes through the storage bin and is fixedly connected to the slide plate.
[0020] By adopting the above technical solution, when the push plate drives the slide plate to slide towards the discharge end of the storage bin, the slide plate drives the pull rope to move, and the pull rope pulls the elastic winding component to wind up. The elastic winding component stores elastic potential energy. When the first air supply channel stops supplying air, the elastic winding component releases the elastic potential energy and pulls the slide plate to move and reset through the pull rope.
[0021] Preferably, the storage bin is provided with a guide rail on the inner wall of the first chute along the direction of the first chute, the slide plate is provided with a guide groove, the guide rail is located in the guide groove, and the pull rope is slidably arranged in the guide rail.
[0022] By adopting the above technical solution, during the process of the skateboard sliding in the first slide groove, the guide rail and guide groove guide the movement of the skateboard, making the skateboard slide more stably in the first slide groove. At the same time, the pull rope slides in the guide rail, making the movement of the pull rope in the first slide groove more stable.
[0023] Preferably, rollers are provided on both opposite side walls of the slide plate, and the rollers abut against the side wall of the first slide groove.
[0024] By adopting the above technical solution, the skateboard moves in the first slide groove, driving the roller to move. The roller rolls on the side wall of the first slide groove, making the skateboard slide more stably in the first slide groove.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Utilizing the first air supply channel, after all the rivets in the rivet track are fed into the storage bin, the first air supply channel blows gas into the discharge chute through the discharge port. After the gas enters the storage bin, it blows the rivets at the bottom of the storage bin toward the rivet gun at the discharge end, so that all the rivets in the storage bin can be fed into the rivet gun, thereby improving the continuous operation capability of the riveting system and improving the overall work efficiency. 2. With the help of the second air supply channel, when the rivet at the bottom of the feed chute enters the discharge port, the second air supply channel blows gas into the rivet receiving track. The gas pushes the rivet to slide in the rivet receiving track and the feed chute, thus facilitating the smooth entry of the rivet into the discharge port. 3. Through the guide seat and guide rod, when the nail feeding mechanism and the nail receiving mechanism begin to dock, the nail receiving mechanism drives the guide seat to move closer to the guide rod, and the two guide rods are inserted into the two guide holes, thereby guiding the docking of the nail feeding mechanism and the nail receiving mechanism, making the docking more accurate.

[0028] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.
[0029] This application discloses a mechanical nail feeding station.
[0030] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A mechanical nail feeding station includes a nail feeding mechanism 4, a nail receiving mechanism 5, and a storage bin 1. The nail feeding mechanism 4 is installed on a nail feeding box, and the nail receiving mechanism 5 and the storage bin 1 are installed on a robotic arm. The discharge end of the nail receiving mechanism 5 is connected to the inlet end of the storage bin 1, and the discharge end of the storage bin 1 is connected to a rivet gun.
[0031] The nail feeding mechanism 4 includes a second fixed base 41 and a nail feeding track 42. The second fixed base 41 is fixedly installed on the nail feeding box, and the nail feeding track 42 is fixedly installed on the second fixed base 41, with two conveying channels formed inside the nail feeding track 42. A second sealing plate 13 is rotatably installed at the bottom of the nail feeding track 42. The second sealing plate 13 rotates to the bottom of the nail feeding track 42 under the action of gravity and seals the bottom end of the nail feeding track 42.
[0032] The pin-attaching mechanism 5 includes a first fixed base 51 and two pin-attaching tracks 52. The first fixed base 51 is fixedly mounted on the robotic arm, and the two pin-attaching tracks 52 are fixedly mounted on the first fixed base 51 and are parallel to each other. A pin-attaching seat 3 is fixedly mounted on the top of the first fixed base 51, and the top ends of the two pin-attaching tracks 52 are fixedly mounted inside the pin-attaching seat 3.
[0033] A first sealing plate 14 is rotatably mounted on the top wall of the pin receiving seat 3 above the two pin receiving tracks 52. Pull plates 15 are symmetrically fixed on the opposite side walls of the pin receiving seat 3. Each pull plate 15 is connected to an elastic element 16, and the ends of the two elastic elements 16 away from the pull plates 15 are respectively connected to the opposite side walls of the first sealing plate 14. In this application, the elastic element 16 can be a tension spring, and the two elastic elements 16 pull the first sealing plate 14 to rotate and seal the top ends of the two pin receiving tracks 52.
[0034] A push rod 20 is fixedly installed vertically on the bottom wall of the second fixed base 41. A first trigger wheel 19 is rotatably installed on one side of the first sealing plate 14. The first trigger wheel 19 moves to contact the push rod 20. A push block 17 is fixedly installed on the side wall of the second sealing plate 13. A second trigger wheel 18 is rotatably installed on the side wall of the pin holder 3. The second trigger wheel 18 moves to contact the push block 17.
[0035] When the nail receiving mechanism 5 and the nail supply mechanism 4 begin to connect, the robotic arm drives the nail receiving mechanism 5 to move upward and approach the nail supply mechanism 4. The first trigger wheel 19 moves to contact the push rod 20 and drives the first sealing plate 14 to rotate and open the nail receiving track 52. Then the second trigger wheel 18 moves to contact the push block 17 and drives the second sealing plate 13 to rotate and open the nail supply track 42. After the nail supply track 42 and the nail receiving track 52 are connected, the nail supply operation can begin.
[0036] A guide seat 21 is fixedly installed on the top of the first fixed seat 51. Guide holes 23 are provided on both sides of the first trigger wheel 19 in the guide seat 21. Guide rods 22 are fixedly installed on the bottom wall of the second fixed seat 41 and on both sides of the push rod 20 in the vertical direction.
[0037] When the nail feeding mechanism 4 and the nail receiving mechanism 5 initiate the docking process, the nail receiving mechanism 5 drives the guide seat 21 to move in opposite directions along the axial direction of the guide rod 22, so that the two guide rods 22 are respectively inserted into the corresponding guide holes 23, forming a sliding fit. This structure achieves coaxial guidance of the system docking process through the clearance fit between the rod and the hole, effectively constraining the docking degree of freedom, thereby ensuring relative positional accuracy and improving the positioning accuracy and reliability of the docking operation.
[0038] Reference Figure 1 , Figure 3 and Figure 4 The bottom of the first fixed base 51 is fixedly installed with a feeding base 2. The top of the feeding base 2 has two parallel feeding grooves 6, and the bottom ends of the two connecting rails 52 are respectively inserted into the two feeding grooves 6. The bottom of the feeding base 2 has a discharge groove 7, which is located between the two feeding grooves 6. The feeding end of the storage bin 1 is fixedly inserted into the discharge groove 7.
[0039] A feeding block 8 is slidably installed horizontally inside the feeding base 2. The feeding block 8 is located between the feeding chute 6 and the discharging chute 7, and a feeding port 9 is opened in the middle of the feeding block 8. A first driving component 10 is fixedly installed on one side of the feeding base 2. In this application, the first driving component 10 can be a servo motor. The driving end of the first driving component 10 is connected to the feeding block 8 and drives the feeding block 8 to reciprocate within the feeding base 2. The feeding block 8 drives the feeding port 9 to reciprocate continuously between the bottom ends of the two feeding chute 6, so that the feeding port 9 sequentially connects the top end of the discharging chute 7 and the bottom end of the two feeding chute 6.
[0040] The feeding seat 2 has a first air supply channel 11, which is connected to the air supply equipment via a connector. The air outlet of the first air supply channel 11 is located directly above the top of the discharge chute 7, and the first air supply channel 11 is connected to the discharge chute 7 via the feeding port 9. The pin-receiving seat 3 has two second air supply channels 12, both of which are connected to the air supply equipment via connectors. The two second air supply channels 12 are respectively connected to the top of the two pin-receiving rails 52, and the second air supply channels 12 are connected to the feeding chute 6 via the pin-receiving rails 52.
[0041] The implementation principle of a mechanical nail feeding station in this application embodiment is as follows: When the nail receiving mechanism 5 and the nail feeding mechanism 4 begin to connect, the robotic arm drives the nail receiving mechanism 5 to move upward and approach the nail feeding mechanism 4. The first trigger wheel 19 moves to contact the push rod 20 and drives the first sealing plate 14 to rotate and open the nail receiving track 52. Then the second trigger wheel 18 moves to contact the push block 17 and drives the second sealing plate 13 to rotate and open the nail feeding track 42. After the nail feeding track 42 and the nail receiving track 52 are connected, the nail feeding operation can begin.
[0042] After replenishment, rivets 36 are stored in the storage bin 1 and the two rivet receiving tracks 52. The first drive unit 10 drives the feeding block 8 to perform reciprocating linear motion. Its working cycle is divided into two stages: First, the feeding port 9 in the feeding block 8 moves to align with any of the feeding chutes 6. At this time, the second air supply channel 12 blows air, and the rivets 36 at the bottom of the feeding chutes 6 move into the feeding port 9, where the feeding block 8 receives one rivet 36. Then, the feeding block 8 moves in the opposite direction until the feeding port 9 aligns with the discharge chutes 7. At this time, the first air supply channel 11 blows air, and the rivet 36 is unloaded into the storage bin 1 via the discharge chutes 7. Through the continuous reciprocating motion of the feeding block 8, the rivets 36 in the two rivet receiving tracks 52 can be transferred to the storage bin 1 in an alternating and orderly manner.
[0043] After all the rivets 36 in the riveting track 52 have been transferred to the storage bin 1, the system initiates a pneumatic emptying process: the first air supply channel 11 injects gas into the bottom of the storage bin 1 via the discharge port 9 and the discharge chute 7. This airflow pushes the rivet group 36 accumulated at the bottom of the bin toward the rivet gun at the discharge end, achieving complete emptying of the storage bin 1 and forced delivery of the rivets 36. This ensures 100% utilization of the rivets 36, eliminates residue in the bin, and significantly improves the continuous operation capability and overall production efficiency of the riveting system.
[0044] Example 2: Reference Figure 5 The difference between this embodiment and Embodiment 1 is that chamfers are formed on both sides of the outlet of the first air supply channel 11 inside the feeding seat 2, and the two chamfers are located on both sides near the two feeding chutes 6. An air supply groove 24 is formed between the chamfer and the feeding block 8 in the feeding seat 2. When the feeding port 9 connects the first air supply channel 11 and the discharge chute 7, the air supply groove 24 connects the feeding chute 6 and the discharge chute 7.
[0045] The implementation principle of Embodiment 2 of this application is as follows: After all the rivets 36 are transferred to the storage bin 1, the system starts dual airflow supply: the first air supply channel 11 injects airflow into the discharge chute 7 through the discharge port 9, and at the same time the second air supply channel 12 supplies air to the feed chute 6 through the rivet receiving track 52. The airflow of the two feed chute 6 flows into the discharge chute 7 through the air supply groove 24, forming a superimposed airflow effect, thereby increasing the total airflow in the discharge chute 7, which helps to push the rivets 36 at the bottom of the storage bin 1 into the rivet gun.
[0046] Example 3: Reference Figure 6 and Figure 7The difference between this embodiment and Embodiment 2 is that an elastic winding assembly 29 and a drive assembly 30 are installed on the feed end of the storage bin 1. A first chute 25 and a second chute 26 are formed within the storage bin 1. The width of the first chute 25 is greater than the width of the second chute 26. The first chute 25 and the second chute 26 are interconnected and form a T-shaped chute. The rivet 36 is slidably conveyed within the chute, with the rivet head located within the first chute 25 and the rivet body located within the second chute 26.
[0047] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 The storage bin 1 has a sliding plate 27 slidably mounted within the first slide groove 25. Rollers 33 are rotatably mounted on opposite side walls of the sliding plate 27, with each roller abutting against the opposite side walls of the first slide groove 25, allowing the sliding plate 27 to slide smoothly within the first slide groove 25. Two guide rails 31, with an L-shaped cross-section, are spaced apart on the bottom wall of the storage bin 1 within the first slide groove 25. The sliding plate 27 is slidably mounted on the two guide rails 31. The guide rails 31 guide the sliding of the sliding plate 27, thereby further improving the stability and smoothness of the sliding. Simultaneously, a stop is formed at the end of the guide rail 31 to prevent the sliding plate 27 from slipping off the end of the guide rail 31.
[0048] The elastic winding assembly 29 is connected to the slide plate 27. When the slide plate 27 slides to the discharge end of the storage bin 1, the elastic winding assembly 29 can pull the slide plate 27 to move and reset to the feed end of the storage bin 1. A push plate 28 is rotatably mounted on the slide plate 27 via a damping shaft. The drive end of the drive assembly 30 is connected to the push plate 28, and the drive assembly 30 is used to push the push plate 28 to rotate into the second slide groove 26 and pull the push plate 28 to rotate into the first slide groove 25.
[0049] Specifically, the drive assembly 30 includes a drive frame 301, a second drive member 302, a slider 303, a drive rod 304, a drive block 305, and a drive frame 306. The drive frame 301 is fixedly installed on the outer wall of the feed end of the storage bin 1. The slider 303 is slidably installed inside the drive frame 301. The second drive member 302 is fixedly installed on the drive frame 301. A lead screw is fixedly installed at the drive end of the second drive member 302, and the lead screw thread passes through the slider 303. In this application, the second drive member 302 can be selected as a servo motor. The second drive member 302 drives the slider 303 to reciprocate within the drive frame 301 via the lead screw.
[0050] The drive rod 304 slides through the storage bin 1, with one end of the drive rod 304 fixedly connected to the slider 303. The drive block 305 is fixedly installed at the other end of the drive rod 304 and located inside the storage bin 1. The drive frame 306 is fixedly installed on the push plate 28, and the drive block 305 is slidably installed inside the drive frame 306. The end of the drive frame 306 away from the slide plate 27 is open, and the drive block 305 can slide out of or into the drive frame 306 from the open end.
[0051] The second driving component 302 transmits power to the driving block 305 via the slider 303 and the driving rod 304, causing the driving block 305 to move linearly within the driving frame 306. When the push plate 28 needs to rotate into the second slide groove 26, the driving block 305 moves towards the opening end of the driving frame 306, thereby pushing the push plate 28 to rotate and open. Once the driving block 305 is completely disengaged from the driving frame 306, the push plate 28 reaches its maximum rotation angle and is positioned in the second slide groove 26, entering a ready-to-drive state. At this time, the airflow can push it to slide within the slide groove, thereby pushing the rivet 36 towards the discharge end.
[0052] After the operation is completed, the push plate 28 is reset by the elastic winding assembly 29, and the drive block 305 moves in the opposite direction, re-entering the drive frame 306 from the open end. As the drive block 305 continues to move, it applies a reverse torque to the push plate 28 through the drive frame 306, causing the push plate 28 to rotate back to its initial position within the first groove 25, awaiting the next round of rivet 36 insertion. Furthermore, the end of the push plate 28 away from the slide plate 27 is bent at an angle towards the bottom wall of the first groove 25 to form a guide plate 34. When the push plate 28 retracts into the first groove 25, the end of the guide plate 34 away from the push plate 28 is in contact with the bottom wall of the first groove 25, ensuring that the push plate 28 does not interfere with the movement of the rivet 36.
[0053] Specifically, the flexible winding assembly 29 includes a winding box 291, a flexible winding member, and a pull rope 292. The winding box 291 is fixedly installed on the outer wall of the feed end of the storage bin 1. The flexible winding member is installed inside the winding box 291. In this application, the flexible winding member can be a coil spring. The inner end of the flexible winding member is fixedly connected to the middle of the winding box 291, and the outer end of the flexible winding member is fixedly connected to the pull rope 292, which is wound around the flexible winding member. A support wheel 35 is installed on the outer wall of the storage bin 1. The other end of the pull rope 292 passes through the support wheel 35 and through the storage bin 1. The end of the pull rope 292 away from the flexible winding member is fixedly connected to the inner wall of the slide plate 27, and the pull rope 292 is located between the other two guide rails 31.
[0054] When the push plate 28 drives the slide plate 27 to slide towards the discharge end of the storage bin 1, the slide plate 27 will simultaneously pull the pull rope 292, causing the pull rope 292 to move between the two guide rails 31. After the pull rope 292 moves, it causes the elastic winding component to tighten and store elastic potential energy. When the first air supply channel 11 stops supplying air and the power source is cut off, the elastic winding component will release its stored elastic potential energy and drive the slide plate 27 to automatically reset through the pull rope 292.
[0055] The implementation principle of Embodiment 3 of this application is as follows: When the rivets 36 are stored in the storage bin 1 and the two rivet-receiving tracks 52, the drive assembly 30 drives the rotating plate to rotate into the first slide groove 25, so that the push plate 28 and the slide plate 27 are both in the first slide groove 25, ensuring that they do not interfere with the path of the rivets 36. After all the rivets 36 in the rivet-receiving tracks 52 are sent into the storage bin 1, the drive assembly 30 then drives the rotating plate to rotate out of the first slide groove 25 and into the second slide groove 26. At this time, the first air supply channel 11 is activated, and the airflow enters the first slide groove 25 and the second slide groove 26 through the discharge slide groove 7, respectively. The airflow drives the push plate 28 and the slide plate 27 to move inside the storage bin 1. The push plate 28 then pushes the rivets 36 to move towards the discharge end inside the storage bin 1, completing the entire supply to the rivet gun. After the rivets 36 are exhausted, the first air supply channel 11 is closed, and the elastic reset component immediately activates to pull the slide plate 27 and the push plate 28 back to their initial positions. The drive component 30 then drives the rotating plate to reset to the first slide groove 25, and the system returns to the ready state, waiting for the next round of rivet 36 to be filled.
