Description

Technical Field

[0001] This invention relates to the field of aviation assembly equipment technology, and in particular to a rivet storage box and an automatic rivet loading system. Background Technology

[0002] In the aerospace assembly field, it is often necessary to assemble and store rivets of specific specifications for subsequent drilling and riveting. However, in existing technologies, this assembly process is mostly rivet loading, and current rivet loading devices ultimately load and store the rivets in a rivet storage box. During the loading process, to improve loading efficiency, multiple rivets are usually blown into the storage tube of the rivet storage box simultaneously using high-pressure air. However, because the high-pressure air is obstructed in the storage tube, it flows backward, causing some rivets to enter the storage tube, resulting in resistance for subsequent rivets entering, thus affecting the loading efficiency of the storage box. Therefore, there is an urgent need for a rivet storage box and an automatic rivet loading system that can reduce the resistance during rivet loading and improve loading and production efficiency. Summary of the Invention

[0003] In view of the above-mentioned problems of the prior art, this application provides a rivet storage box and an automatic rivet loading system, which can reduce the resistance during rivet loading and improve loading efficiency and production efficiency.

[0004] This application provides a rivet storage box, comprising: a box body; an inlet connector disposed on the box body, the inlet connector having an inlet channel therein; an outlet connector disposed on the box body, the outlet connector having an outlet channel therein; a storage tube disposed within the box body, one end of the storage tube communicating with the inlet channel and the other end communicating with the outlet channel, the middle portion of the storage tube being coiled multiple times; and an exhaust valve communicating with the inlet channel.

[0005] As described above, during the process of blowing material into the storage pipe through the feed inlet using high-pressure air, as the amount of material in the storage pipe increases, the high-pressure air will create a reverse flow within the pipe. This causes the resistance to material entering the storage pipe to gradually increase, making it difficult for the material to enter and easily leading to blockage. In this application, by installing an exhaust valve connected to the feed channel, excess gas in the feed channel can be discharged, reducing the resistance to material entering the storage pipe. This allows for smoother material loading and improves loading efficiency.

[0006] As one possible implementation of the first aspect, the discharge connector is provided with a first air blowing channel, one end of the first air blowing channel is located outside the box and is used to connect to an air pump, and the other end of the air blowing channel is located inside the box and is connected to the inlet channel through an air blowing pipe.

[0007] As described above, by setting up the first air blowing channel and air blowing pipeline, when it is necessary to discharge the material in the storage pipe, after the discharge connector is connected, high-pressure air can be blown into the inlet channel through the first air blowing channel and air blowing pipeline. In this way, the high-pressure air can push the material in the storage pipe toward the discharge channel so as to discharge the material.

[0008] As one possible implementation of the first aspect, the exhaust valve is installed on the air blowing pipe. The exhaust valve includes a first interface, a second interface, and an exhaust port. The first interface is connected to the feed channel through the air blowing pipe, the second interface is connected to the air blowing channel through the air blowing pipe, and the first interface is connected to the exhaust port. Air flows unidirectionally from the second interface to the first interface.

[0009] Therefore, the exhaust valve can be installed on the air blowing pipe, allowing the exhaust valve to reuse the air blowing pipe and connect to the feed channel. This simplifies the structure of the rivet storage box and reduces its cost.

[0010] As one possible implementation of the first aspect, the discharge connector is provided with a first stop and a second stop. The first stop and the second stop extend into / out of the discharge channel radially. There are two of each of the first and second stops. The two first stops and the two second stops are symmetrically arranged along the diameter of the discharge channel. When viewed along the axial direction of the discharge channel, the first stops and the second stops are arranged in a cross shape. The distance between the first stops and the second stops in the axial direction of the discharge channel is adapted to the length of the material.

[0011] As described above, materials can be conveniently and reliably discharged one by one from the discharge channel, avoiding material jamming. This makes the material discharge process smoother, thereby improving the user experience.

[0012] As one possible implementation of the first aspect, the box is provided with an information chip, which stores information about the material in the storage tube.

[0013] Therefore, when loading materials into the rivet storage box, the information chip can record the material information. When controlling the material output from the rivet storage box, the information chip can also be used to facilitate control of the rivet storage box. This improves the automation control capability.

[0014] A second aspect of this application provides an automatic rivet loading system, comprising: a frame with a rivet loading area; and a rivet storage box, at least one of which is disposed in the rivet loading area and detachably connected to the frame, wherein the rivet storage box is any one of the rivet storage boxes described in the first aspect of this application.

[0015] As one possible implementation of the second aspect, the automatic rivet loading system further includes: a feeding interface disposed in the rivet loading area, located at a position corresponding to the feeding connector of the rivet storage box, the feeding connector being pluggable to the feeding interface, the feeding interface being used to output material, allowing the material to enter the storage tube through the feeding connector; a cylinder mounted on the feeding interface, used to blow air into the feeding channel of the feeding connector, causing the material to move to a position close to the discharge connector of the rivet storage box; a first discharge interface disposed in the rivet loading area, located at a position corresponding to the discharge connector of the rivet storage box, the discharge connector being pluggable to the first discharge interface; and a vacuum generator mounted on the first discharge interface, used to draw air from the discharge channel of the discharge connector.

[0016] As described above, once the material moves into the inlet, the high-pressure air blown by the cylinder drives the rivet along the storage tube to a position near the outlet. This prevents the material from being unable to reach the outlet position in the storage tube due to excessive distance when the loading and unloading device pushes the material into the rivet storage box using high-pressure gas, thus avoiding gaps in the storage tube and ensuring complete filling. Simultaneously, by using a vacuum generator to extract air from the outlet, the material in the storage tube moves more smoothly towards the outlet under the pressure of high-pressure air, further improving the loading efficiency of the rivet storage box.

[0017] As one possible implementation of the second aspect, the frame is provided with a nail removal area; it also includes: a cleaning box; a second discharge port, which is located in the nail loading area at a position corresponding to the discharge connector, the discharge connector being plugged into and plugged into the second discharge port, and the second discharge port being connected to the cleaning box through a cleaning pipe; the second discharge port is provided with a second air blowing channel, one end of which is used to connect to an air pump, and the other end is connected to one end of the first air blowing channel of the discharge connector after the second discharge port is connected to the discharge connector, and the first air blowing channel is connected to the inlet channel through an air blowing pipe.

[0018] As described above, by setting up a rivet unloading area, the rivet storage box can be conveniently installed in the rivet unloading area when it is necessary to empty the rivet storage box. The discharge connector is connected to the second discharge interface, and high-pressure air is blown into the feed channel through the second air blowing channel, the first air blowing channel and the air blowing pipeline, thereby driving the material in the storage tube to be discharged from the discharge connector and transported to the cleaning box.

[0019] As one possible implementation of the second aspect, the cleaning pipe is provided with a bend, and the material of the cleaning pipe is softer than the material of the material.

[0020] Therefore, by making the material of the cleaning pipe softer than the material, the material can be transported in the cleaning pipe under the propulsion of high-pressure air, thus avoiding damage caused by collision with the cleaning pipe.

[0021] As one possible implementation of the second aspect, the cleaning pipe is provided with a bend, and a buffer is provided inside the bend.

[0022] As described above, when the material moves along the cleaning pipe under the propulsion of high-pressure air, it will collide with the cleaning pipe at the bend. By installing a buffer in the bend, the impact force between the material and the cleaning pipe can be reduced, thus preventing damage to the material due to the collision.

[0023] These and other aspects of the invention will become more apparent from the following description of several embodiments. Attached Figure Description

[0063] The term "an embodiment" or "an embodiment" as used in this specification means that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in at least one embodiment of the invention. Therefore, the terms "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0064] Below, with reference to the accompanying drawings, possible embodiments of the rivet feeding device 3 in this application will be described by way of example.

[0065] This application provides a rivet feeding device 3 for supplying rivets to a rivet loading and unloading device 5. The device includes a conveyor belt 311, a cleaning machine 313, a first feeding pipe 331, a storage component 332, a third stop component 333, and a third drive cylinder 334. The conveyor belt 311 transports rivets. The cleaning machine 313 is located on one side of the conveyor belt 311 and removes rivets from the conveyor belt 311 that have been transported to the corresponding position on the cleaning machine 313. The first feeding pipe 331 is located below the end of the conveyor belt 311. Rivets transported on the conveyor belt 311 fall into the first feeding pipe 331 from its upper end and exit from its lower end. The storage component 332 has a vertically arranged through-hole storage channel 3321, which communicates with the lower end of the first feeding pipe 331. Rivets exiting from the first feeding pipe 331 fall into the storage channel 3321. The third stop 333 is mounted on the storage component 332 and extends into the storage channel 3321 from the outside of the storage component 332. The third drive cylinder 334 is connected to the third stop 333, driving the third stop 333 to extend into the storage channel 3321 to stop the rivet in the storage channel 3321, or to pull it out of the storage channel 3321 so that the rivet is output from the storage channel 3321. Multiple storage components 332, third stop 333, and third drive cylinders 334 are correspondingly arranged, and multiple storage components 332 are stacked vertically, with their storage channels 3321 connected. The length of the storage channel 3321 is adapted to the number of rivets, and the number of storage components 332 is greater than or equal to the number of rivets on the conveyor belt 311 behind the cleaning machine 313. When the loading and unloading device 5 jams, the cleaning machine 313 removes the rivets that are located in front of the cleaning machine 313 from the conveyor belt 311. Each third drive cylinder 334 drives the third stop 333 to store one rivet in a storage channel 3321.

[0066] Therefore, in this application, by providing a third stop 333 on the storage component 332, the third drive cylinder 334 can drive the third stop 333 to extend into the storage channel 3321, thereby stopping and storing the rivet in the storage channel 3321. By adapting the length of the storage channel 3321 to the rivet, the storage channel 3321 can be used to store only one rivet, thus avoiding rivet jamming failures that may occur when storing multiple rivets.

[0067] In addition, when the loading and unloading device 5 jams, the cleaning machine 313 is controlled to remove the rivets that are in front of the cleaning machine 313 (in the direction of material inflow) from the conveyor belt 311. This can prevent too many rivets from continuing to be fed to the loading and unloading device 5 when jamming occurs, thus preventing the jamming failure from becoming more serious.

[0068] Meanwhile, by ensuring that the number of storage units 332 is greater than or equal to the number of rivets on the conveyor belt 311 behind the cleaning machine 313, when jamming occurs in the rivet loading and unloading device 5, all rivets conveyed by the conveyor belt 311 to the first feed pipe 331 can be stored in the stacked storage units 332, preventing jamming due to skewness when rivets are stored in the first feed pipe 331. This improves assembly and production efficiency.

[0069] In some embodiments, the rivet feeding device 3 further includes multiple sensors, each corresponding to a storage member 332, for detecting whether there are rivets in the storage channel 3321. For two adjacent storage members 332, when the sensor detects that there are rivets in the storage channel 3321 of the upper storage member 332 and there are no rivets in the storage channel 3321 of the lower storage member 332, the third drive cylinder 334 corresponding to the upper storage member 332 drives the third stop member 333 to be pulled out from the storage channel 3321.

[0070] As described above, by using sensors to detect whether there are rivets in each storage channel 3321, it is possible to easily control the rivets to fall into the lower storage channel 3321 only when there are no rivets in the lower storage channel 3321. This avoids multiple rivets being in the same storage channel 3321, thereby preventing rivet jamming and improving assembly and production efficiency.

[0071] In some embodiments, after the third drive cylinder 334 drives the third stop 333 to be pulled out of the storage channel 3321 from the first time threshold, the third drive cylinder 334 drives the third stop 333 to extend into the storage channel 3321. Therefore, by having the third drive cylinder 334 drive the third stop 333 to be pulled out of the storage channel 3321 from the first time threshold and then extend into the storage channel 3321, not only can the control difficulty of the third drive cylinder 334 be reduced, but the feeding rhythm of the rivet feeding device 3 can also be accelerated.

[0072] In some embodiments, after the sensor corresponding to the uppermost or lowermost storage component 332 detects that the duration of the presence of rivets in the storage channel 3321 exceeds a second time threshold, the cleaning machine 313 removes all rivets conveyed to the corresponding position on the conveyor belt 311 from the conveyor belt 311.

[0073] Therefore, when the loading and unloading rivet device experiences a jam, even if the third stop 333 in the lowest storage component 332 is pulled out of the storage channel 3321, the rivets in the storage component 332 will still be unable to fall out of the storage channel 3321 due to the blockage caused by the rivets below. Thus, when the sensor corresponding to the lowest storage component 332 detects that the rivets in the storage channel 3321 have been present for a duration exceeding the second threshold, it can be determined that a jam has occurred in the loading and unloading rivet device 5. This allows the cleaning machine 313 to be controlled in a timely manner to remove subsequent rivets from the conveyor belt 311, preventing the blockage from worsening.

[0074] Furthermore, to meet the rivet handling rhythm of the rivet loading and unloading device 5, the feeding rhythm of the rivet feeding device 3 is usually set to be greater than that of the rivet loading and unloading device 5, which makes it easy for multiple storage units 332 to become full. Therefore, when the sensor corresponding to the uppermost storage unit 332 detects that there are rivets in the storage channel 3321 for a continuous period of time exceeding the second threshold, it can be determined that the storage unit 332 is full. This allows the cleaning machine 313 to be controlled in a timely manner to remove subsequent rivets from the conveyor belt 311, thereby reducing the number of rivets that may be stored in the first feeding pipe 331 and reducing the possibility of rivets getting stuck in the first feeding pipe 331.

[0075] In some embodiments, the rivet feeding device 3 further includes a first frame 1, a conveyor belt 311 fixedly mounted on the first frame 1, a storage component 332 fixedly connected to a first feeding pipe 331, an upper end of the first feeding pipe 331 detachably connected to the first frame 1, and the storage component 332 at the lowest end detachably connected to the first frame 1. Therefore, the first feeding pipe 331 and the storage component 332 can be easily replaced according to the type and size of the rivet, making the movement of the rivet in the first feeding pipe 331 and the storage component 332 more stable and smooth, reducing the possibility of jamming. Furthermore, when a malfunction such as jamming occurs in the first feeding pipe 331 and the storage component 332, the first feeding pipe 331 and the storage component 332 can be easily replaced, thereby promptly eliminating the fault and reducing the impact on production efficiency.

[0076] In some embodiments, the rivet feeding device 3 further includes: a first connector 321, which is fixedly mounted on the first frame 1 and located at the end of the conveyor belt 311. A vertical second feeding pipe 3211 is provided at the lower end of the first connector 321, allowing rivets falling from the end of the conveyor belt 311 to fall into the second feeding pipe 3211; and a second connector 322, which is hinged to the first frame 1. A vertically arranged sixth connecting hole in the shape of a through hole is provided on the second connector 322. When the second connector 322 is rotated to a predetermined position, the sixth connecting hole connects the first feeding pipe 331 and the second feeding pipe 3211. Thus, by rotating the second connector 322, the sixth connecting hole can connect the first feeding pipe 331 and the second feeding pipe 3211, or the first feeding pipe 331 and the second feeding pipe 3211 can be separated. This facilitates the installation and removal of the first feeding pipe 331.

[0077] In some embodiments, the rivet feeding device 3 further includes a positioning member 323, which is a magnetic component used to attract the second connecting member 322. The positioning member 323 is fixedly installed on the first frame 1, and when the second connecting member 322 rotates to a predetermined position, it abuts against the positioning member 323. Thus, by providing the positioning part, the upper end of the first feeding tube 331 can be positioned, thereby facilitating the installation of the upper end of the first feeding tube 331. Simultaneously, the positioning part can magnetically attract the second connecting member 322, thereby actively attracting the second connecting member 322 to a predetermined position and abutting against the positioning part. Therefore, when installing the first feeding tube 331, it can assist the operator in the installation, making the installation of the first feeding tube 331 more convenient.

[0078] In some embodiments, the upper end of the first feed pipe 331 is detachably connected to the second connector 322 via a first hand-tightening bolt 324; and / or, the storage component 332 at the lowest end is detachably connected to the first frame 1 via a second hand-tightening bolt 336. Thus, the first feed pipe 331 and the storage component 332 at the lowest end can be easily installed and removed using the first hand-tightening bolt 324 and the second hand-tightening bolt 336, thereby reducing the difficulty of assembling and disassembling the first feed pipe 331 and the storage component 332.

[0079] In some embodiments, the rivet feeding device 3 further includes a steering station 314, which includes a steering component 3141 and a motor 3142. The steering component 3141 is positioned above the conveyor belt 311, and its lower surface has a through-groove steering groove 3143 through which rivets on the conveyor belt 311 pass. The length of the steering groove 3143 is 5 mm longer than the rivet. The motor 3142 is connected to the steering component 3141 and drives it to rotate, rotating the rivets on the conveyor belt 311 in the opposite direction by 180°. Thus, by making the length of the steering groove 3143 5 mm longer than the rivet, the control difficulty of the steering station 314 is reduced, and the stability when driving the rivet to rotate is improved.

[0080] The above description provides an exemplary embodiment of the rivet feeding device 3 in this application. Below, with reference to the accompanying drawings, an exemplary embodiment of the rivet loading / unloading channel 547 switching device 6 in this application will be described.

[0081] This application also provides a rivet loading / unloading channel 547 switching device 6 for connecting a rivet loading / unloading device 5 and a rivet storage box 72. The rivet loading / unloading device 5 has multiple loading / unloading channels 547, and the rivet loading / unloading device 5 sequentially stores a predetermined quantity of material in the multiple loading / unloading channels 547. The rivet loading / unloading channel 547 switching device 6 includes a first connecting plate 61, a second connecting plate 62, a connecting pipe 64, a magnetic suction element 69, and a first driving cylinder 65. The first connecting plate 61 has a through-hole-shaped first connecting hole 611, which is pipe-connected to one side surface of the first connecting plate 61 and the rivet storage box 72. The second connecting plate 62 has through-hole-shaped second connecting holes 621, with multiple second connecting holes 621 corresponding to the loading / unloading channels 547. The multiple second connecting holes 621 are arranged along a first direction, and one side surface of the second connecting plate 62 is attached to the other side surface of the first connecting plate 61, and is slidably connected to the first connecting plate 61 along the first direction. Multiple connecting pipes 64 are correspondingly provided with second connecting holes 621. The loading and unloading channel 547 is vertically arranged, and the second connecting holes 621 are horizontally arranged. The middle bends of the connecting pipes 64 connect the second connecting holes 621 and the loading and unloading channel 547 respectively. Magnetic suction element 69 is provided on at least one connecting pipe 64, located between the bend and the second connecting hole 621. The first drive cylinder 65 is drivenly connected to the second connecting plate 62, driving the second connecting plate 62 to slide along a first direction, so that one of the second connecting holes 621 communicates with the first connecting hole 611.

[0082] As described above, by setting a magnetic suction element 69 between the bend of the connecting tube 64 and the second connecting hole 621, the material can be attracted by magnetic force after falling and turning in the connecting tube 64, forming a magnetic damping mechanism to reduce the speed of the material and prevent the material from impacting the end of the connecting tube 64 due to excessive force. This keeps the material in the position corresponding to the first connecting hole 611 and the second connecting hole 621, thereby avoiding jamming failure when the first connecting hole 611 switches between multiple second connecting holes 621, and thus improving assembly efficiency and production efficiency.

[0083] In some embodiments, the magnetic force of the magnetic suction member 69 is configured such that when material falls into the connecting tube 64 under gravity, it can pass through the position of the magnetic suction member 69 and stop inside the connecting tube 64. Thus, by using the magnetic force of the magnetic suction member 69 to stop the material inside the connecting tube 64, jamming can be avoided when switching the connection between the first connecting hole 611 and the second connecting hole 621. Simultaneously, it also prevents material from being attracted to the position corresponding to the magnetic suction member 69, thus avoiding material retention.

[0084] In some embodiments, the magnetic force of the magnetic chuck 69 is three times the weight of the material. This allows for a more suitable magnetic force, preventing material retention due to excessive force and avoiding jamming due to insufficient force.

[0085] In some embodiments, the magnetic attractor 69 is detachably connected to the connecting tube 64, and one or more magnetic attractors 69 are provided on one connecting tube 64. Therefore, the magnetic force can be adjusted by changing the number of magnetic attractors 69 on the connecting tube 64. This reduces the difficulty of adjusting the magnetic force and makes it easier for operators to adjust the magnetic force.

[0086] In some embodiments, the magnetic attractor 69 is disposed near the bend of the connecting tube 64. Thus, the bend of the connecting tube 64 is the peak point (maximum speed) where the material's gravitational potential energy is converted into kinetic energy. By placing the magnetic attractor 69 near the bend, the material can obtain the maximum braking torque, thereby improving the magnetic attraction effect of the magnetic attractor 69.

[0087] In some embodiments, the first connecting plate 61 is further provided with a through-hole-shaped third connecting hole 612, which connects to the cleaning box pipe on one side surface of the first connecting plate 61. The second connecting plate 62 is further provided with a through-hole-shaped fourth connecting hole 622, and multiple fourth connecting holes 622 are provided corresponding to the loading and unloading channel 547. The multiple fourth connecting holes 622 are arranged along the first direction and are located one by one on one side of the second connecting hole 621 along the second direction. The first driving cylinder 65 drives the second connecting plate 62 to slide along the first direction, so that one of the fourth connecting holes 622 communicates with the third connecting hole 612.

[0088] The rivet loading / unloading channel 547 switching device 6 also includes a third connecting plate 63 and a second driving cylinder 66. The third connecting plate 63 has multiple through-hole-shaped fifth connecting holes 631, each corresponding to a different connecting pipe 64. These fifth connecting holes 631 are arranged along a first direction. One surface of the third connecting plate 63 is in contact with the other surface of the second connecting plate 62, and the two plates are slidably connected along a second direction. The second driving cylinder 66 is drively connected to the third connecting plate 63, driving the third connecting plate 63 to slide along the second direction, causing the fifth connecting holes 631 to communicate with either the second connecting hole 621 or the fourth connecting hole 622.

[0089] Therefore, when it is necessary to empty the material in the equipment, the fifth connecting hole 631 can be switched from being connected to the second connecting hole 621 to being connected to the fourth connecting hole 622 by the second driving cylinder 66, so that the material in the equipment can be blown into the cleaning box.

[0090] In some embodiments, the first direction is perpendicular to the second direction. This simplifies the structure of the first connecting plate 61, the second connecting plate 62, and the third connecting plate 63, and facilitates the switching of the first connecting hole 611 between multiple second connecting holes 621 by the first driving cylinder 65 and the second driving cylinder 66, and facilitates the switching of the fifth connecting hole 631 between the second connecting hole 621 and the fourth connecting hole 622.

[0091] In some embodiments, multiple loading and unloading channels 547 are arranged in groups, and multiple groups are provided, with each group of loading and unloading channels 547 adapted to different types of materials. The first connecting hole 611, the second connecting hole 621, the third connecting hole 612, the fourth connecting hole 622, the fifth connecting hole 631, and the connecting pipe 64 are arranged in groups and correspond one-to-one with the multiple loading and unloading channels 547. Therefore, the first connecting hole 611, the second connecting hole 621, the third connecting hole 612, the fourth connecting hole 622, the fifth connecting hole 631, and the connecting pipe 64 can be set according to the type and size of the material, thereby increasing the adaptability range of the rivet loading and unloading channel 547 switching device 6 and reducing the possibility of rivet jamming.

[0092] The above description provides an exemplary description of possible embodiments of the rivet loading / unloading channel 547 switching device 6 in this application. Below, with reference to the accompanying drawings, an exemplary description of possible embodiments of the rivet storage box 72 in this application will be provided.

[0093] This application also provides a rivet storage box 72, which includes a box body 721, an inlet connector 722, an outlet connector 723, a storage tube 724, and an exhaust valve 725. The inlet connector 722 is disposed on the box body 721, and an inlet channel 7221 is provided within the inlet connector 722. The outlet connector 723 is disposed on the box body 721, and an outlet channel 7231 is provided within the outlet connector 723. The storage tube 724 is disposed within the box body 721, with one end connected to the inlet channel 7221 and the other end connected to the outlet channel 7231, and the middle portion of the storage tube 724 is coiled multiple times. The exhaust valve 725 is connected to the inlet channel 7221.

[0094] As described above, during the process of blowing material into the storage pipe 724 through the inlet joint 722 using high-pressure air, as the amount of material in the storage pipe 724 increases, the high-pressure air will flow in reverse within the storage pipe 724. This causes the resistance to the material entering the storage pipe 724 to gradually increase, making it difficult for the material to enter and easily leading to blockage. In this application, by setting an exhaust valve 725 connected to the inlet channel 7221, excess gas in the inlet channel 7221 can be discharged, reducing the resistance to the material entering the storage pipe 724 from the inlet channel 7221. This allows for smoother material loading and improves loading efficiency.

[0095] In some embodiments, a first air blowing channel 7232 is provided inside the discharge connector 723. One end of the first air blowing channel 7232 is located outside the housing 721 and is used to connect to an air pump. The other end of the air blowing channel is located inside the housing 721 and is connected to the inlet channel 7221 through an air blowing pipe. Thus, by providing the first air blowing channel 7232 and the air blowing pipe, when it is necessary to discharge the material in the storage tube 724, after the discharge connector 723 is connected, high-pressure air can be blown into the inlet channel 7221 through the first air blowing channel 7232 and the air blowing pipe. This high-pressure air can then push the material in the storage tube 724 toward the discharge channel 7231 to discharge the material.

[0096] In some embodiments, an exhaust valve 725 is installed on an air blowing pipe. The exhaust valve 725 includes a first interface 7251, a second interface 7252, and an exhaust port 7253. The first interface 7251 is connected to the feed channel 7221 via the air blowing pipe, the second interface 7252 is connected to the air blowing channel via the air blowing pipe, and the first interface 7251 is connected to the exhaust port 7253. Air flows unidirectionally from the second interface 7252 to the first interface 7251. Therefore, the exhaust valve 725 can be installed on the air blowing pipe, allowing it to reuse the air blowing pipe connection to the feed channel 7221. This simplifies the structure of the rivet storage box 72 and reduces its cost.

[0097] In some embodiments, the discharge connector 723 is provided with a first stop and a second stop. The first stop and the second stop extend into / out of the discharge channel 7231 radially. Two of each type of stop are provided, symmetrically arranged along the diameter of the discharge channel 7231. Viewed axially along the discharge channel 7231, the first and second stops are arranged in a cross shape. The axial distance between the first and second stops in the discharge channel 7231 is adapted to the length of the material. This allows for convenient and stable control of the material being discharged one by one from the discharge channel 7231, preventing material jamming. This makes the material discharge process smoother, thereby improving the user experience.

[0098] In some embodiments, an information chip 726 is provided on the housing 721, and the information chip 726 stores information about the material in the storage tube 724. Therefore, when loading material into the rivet storage box 72, the information about the material can be recorded via the information chip 726. When controlling the material output from the rivet storage box 72, the material information recorded in the information chip 726 can also be used to facilitate the control of the rivet storage box 72. This improves the automation control capability.

[0099] The above description provides an exemplary description of possible embodiments of the rivet storage box 72 in this application. Below, with reference to the accompanying drawings, an exemplary description of possible embodiments of the automatic rivet loading system 1000 in this application will be provided.

[0100] This application also provides an automatic rivet loading system 1000, including a first frame 1 and a rivet storage box 72. The first frame 1 has a rivet loading area 711, and at least one rivet storage box 72 is disposed in the rivet loading area 711 and detachably connected to the first frame 1. The rivet storage box 72 is any of the rivet storage box 72 described in the above embodiments.

[0101] In some embodiments, the automatic rivet loading system 1000 further includes an inlet port 73, a cylinder, a first outlet port 74, and a vacuum generator 76. The inlet port 73 is located in the rivet loading area 711, corresponding to the inlet connector 722 of the rivet storage box 72. The inlet connector 722 is pluggable connected to the inlet port 73, and the inlet port 73 is used to output material, allowing the material to enter the storage pipe 724 through the inlet connector 722. The cylinder is mounted on the inlet port 73 and is used to blow air into the inlet channel 7221 of the inlet connector 722, causing the material to move to a position close to the outlet connector 723 of the rivet storage box 72. The first outlet port 74 is located in the rivet loading area, corresponding to the outlet connector of the rivet storage box, and the outlet connector is pluggable connected to the first outlet port 74. The vacuum generator 76 is mounted on the first outlet port 74 and is used to draw air from the outlet channel of the outlet connector.

[0102] As described above, once the material moves into the inlet 722, the high-pressure air blown by the cylinder can drive the rivet along the storage tube 724 to a position near the outlet 723. This prevents the material from being unable to reach the outlet 723 in the storage tube 724 due to excessive distance when the loading / unloading device 5 pushes the material into the rivet storage box 72 using high-pressure gas, thus avoiding gaps in the storage tube 724 and ensuring complete filling. Simultaneously, by using a vacuum generator 76 to draw air from the outlet, the material in the storage tube moves more smoothly towards the outlet under the pressure of high-pressure air, thereby improving the loading efficiency of the rivet storage box.

[0103] In some embodiments, a rivet unloading area 712 is provided on the first frame 1. The automatic rivet loading system 1000 also includes a cleaning box 76 and a second discharge interface 75, wherein the second discharge interface 75 is located in the rivet loading area 711, at the position corresponding to the discharge connector 723, and the discharge connector 723 is plugged into and plugged into the second discharge interface 75. The second discharge interface 75 is connected to the cleaning box 76 through a cleaning pipe 68. A second air blowing channel is provided on the second discharge interface 75. One end of the second air blowing channel is used to connect to an air pump, and the other end is connected to one end of the first air blowing channel 7232 of the discharge connector 723 after the second discharge interface 75 is connected to the discharge connector 723. The first air blowing channel 7232 is connected to the inlet channel 7221 through an air blowing pipe. A vacuum generator 76 is installed on the second discharge interface 75 for drawing air from the discharge channel 7231 of the discharge connector 723.

[0104] As described above, by setting up the rivet removal area 712, the rivet storage box 72 can be conveniently installed in the rivet removal area 712 when it is necessary to empty the rivet storage box 72, so that the discharge connector 723 is connected to the discharge interface, and high-pressure air is blown into the feed channel 7221 through the second air blowing channel, the first air blowing channel 7232 and the air blowing pipe, thereby driving the material in the storage pipe 724 to be discharged from the discharge connector 723 and transported to the cleaning box 76.

[0105] In some embodiments, the cleaning pipe 68 is provided with a bend, and the material of the cleaning pipe 68 is softer than the material of the material. Therefore, by making the material of the cleaning pipe 68 softer than the material, damage caused by collisions with the cleaning pipe 68 can be avoided when the material is conveyed within the cleaning pipe 68 under the propulsion of high-pressure air.

[0106] In some embodiments, the cleaning pipe 68 is provided with a bend, and a buffer is provided within the bend. Thus, when the material moves along the cleaning pipe 68 under the propulsion of high-pressure air, it will collide with the cleaning pipe 68 at the bend. By providing a buffer within the bend, the impact force between the material and the cleaning pipe 68 can be reduced, preventing damage to the material due to the collision.

[0107] The specific structure of the automatic rivet loading system 1000 for aircraft will now be described in detail with reference to the accompanying drawings, in a specific embodiment.

[0108] Figure 1 This is one of the three-dimensional structural schematic diagrams of the rivet automatic loading system 1000 in this application; Figure 2 This is the second three-dimensional structural schematic diagram of the rivet automatic loading system 1000 in this application. Figure 1 , Figure 2As shown, the automatic rivet loading system 1000 adopts a split-type box structure. The upper layer is the material sorting and assembly unit and safety door, and the lower layer integrates the pneumatic circuit unit and control cabinet. The overall dimensions of the automatic rivet loading system 1000 are: length 2085mm × width 1100mm × height 1935mm. The automatic rivet loading system 1000 includes a first frame 1 and a vibratory feeding device 2, a rivet feeding device 3, a spacer block feeding pipe 4, a rivet loading and unloading device 5, a rivet loading and unloading channel 547 switching device 6, a boxing device 7, and a control device 8, all mounted on the first frame 1. The vibratory feeding device 2 is used to provide rivets and spacers (i.e., materials). The rivet feeding device 3 is used to sort and convey the rivets provided by the vibratory feeding device 2 to the rivet loading and unloading device 5, and the spacer block feeding pipe 4 is used to convey the spacers provided by the vibratory feeding device 2 to the rivet loading and unloading device 5. The rivet loading and unloading device 5 is used to assemble the rivets and spacers provided by the vibratory feeding device 2 together. The rivet loading / unloading channel 547 switching device 6 is used to switch the channel connecting the rivet loading / unloading device 5 and the boxing device 7. The boxing device 7 is used to collect assembled rivets and spacers. The control device 8 is electrically connected to the vibratory feeding device 2, the rivet feeding device 3, the rivet loading / unloading device 5, the rivet loading / unloading channel 547 switching device 6, and the boxing device 7, and is used to control the vibratory feeding device 2, the rivet feeding device 3, the rivet loading / unloading device 5, the rivet loading / unloading channel 547 switching device 6, and the boxing device 7.

[0109] Figure 3 for Figure 2 A three-dimensional structural diagram of the vibrating feeding device 2 and the feeding mechanism 31, as shown below. Figure 3 As shown, the vibrating feeding device 2 includes a rivet vibrating plate 21 and a spacer vibrating plate 22 mounted on the first frame 1, used for the automatic dispersion, orderly arrangement, and conveying of rivets and spacers, respectively. Both the rivet vibrating plate 21 and the spacer vibrating plate 22 have a hopper diameter of 500mm and a vibration frequency range of 50Hz-180Hz. The spacer vibrating plate 22 is equipped with a color sensor to identify spacers of different specifications. Both the rivet vibrating plate 21 and the spacer vibrating plate 22 have a material shortage detection function, sending a feeding signal to the control device 8 when there is no material.

[0110] Figure 4 This is one of the three-dimensional structural diagrams of the rivet vibratory feeder 21, the feeding mechanism 31, and the connecting mechanism 32; Figure 5 This is the second three-dimensional structural diagram of the rivet vibratory feeder 21, the feeding mechanism 31, and the connecting mechanism 32; Figure 6 This is a schematic diagram illustrating the rivet alignment process at the steering station 314. (See diagram for example.) Figure 4 , Figure 5As shown, the rivet feeding device 3 includes a feeding mechanism 31, which uses a conveyor belt 311 as the main rivet conveyor and is equipped with a laser switch, a CCD camera 312, a cleaning machine 313, and a turning station 314. The laser switch assists in detecting and counting incoming materials. The CCD camera 312 compares the real-time captured rivet images with preset standard contours to identify the rivet specifications and orientation. The cleaning machine 313 is specifically an air blowing device. When the CCD camera 312 detects rivets of incorrect specifications on the conveyor belt 311, the cleaning machine 313 blows the rivet back to the rivet vibrating plate 21. Figure 6 As shown, when the CCD camera 312 detects that the rivet is in the wrong direction (opposite direction), the rivet with the wrong direction is rotated 180° by the turning station 314 when it passes through the turning station 314 to correct it. The turning station 314 is located behind the cleaning machine 313 (i.e., on the side of the feeding direction of the conveyor belt 311). The turning station 314 can correct the rivets with the wrong direction on the conveyor belt 311, so that the rivets with the wrong direction do not need to be blown back to the rivet vibrating plate 21 by the cleaning machine 313 when they pass through the cleaning machine 313, thereby improving the feeding efficiency of the feeding mechanism 31.

[0111] Figure 7 This is a cross-sectional view of the turning station at position 314. Figure 7 As shown, the steering station 314 includes a steering component 3141 and a motor 3142. The motor 3142 is fixedly mounted on the first frame 1, directly above the conveyor belt 311. The drive shaft of the motor 3142 extends vertically downwards, and the steering component 3141 is fixedly mounted on the drive shaft of the motor 3142. The lower surface of the steering component 3141 is close to the conveyor belt 311 and has a through-groove steering groove 3143. The extending direction of the steering groove 3143 is the same as the conveying direction of the conveyor belt 311, and the rivets on the conveyor belt 311 pass through the steering groove 3143. The motor 3142 is drively connected to the steering component 3141, driving the steering component 3141 to rotate 180°, thereby rotating the rivets on the conveyor belt 311 in the opposite direction by 180°. The length of the steering groove 3143 is 5mm longer than the rivet, which reduces the control difficulty of the steering station 314 and improves the stability when driving the rivet to rotate.

[0112] like Figure 4 , Figure 5As shown, the rivet feeding device 3 also includes a connecting mechanism 32 for connecting the feeding mechanism 31 and the feeding mechanism 33 described below. The connecting mechanism 32 includes a first connecting member 321, a second connecting member 322, a positioning member 323, and a first hand-tightening bolt 324. The first connecting member 321 is fixedly installed on the first frame 1, located directly below the end of the conveyor belt 311, and connected to the end of the conveyor belt 311. A second feeding pipe 3211 is provided at the lower end of the first connecting member 321, allowing rivets falling from the end of the conveyor belt 311 to fall vertically into the second feeding pipe 3211.

[0113] like Figure 4 , Figure 5 As shown, the second connector 322 is located below the first connector 321 and is hinged to the first frame 1. Figure 4 , Figure 5 The position of the second connector 322 in solid line form is the predetermined position, while the position of the second connector 322 in dashed line form is the position where the second connector 322 is rotated to be offset and separated from the first feed pipe 331 and the second feed pipe 3211. A sixth connecting hole in the shape of a through hole is vertically provided on the second connector 322. By rotating the second connector 322, the sixth connecting hole can be positioned directly below the second feed pipe 3211, connecting the upper end of the sixth connecting hole to the lower end of the second feed pipe 3211. A connecting groove 3221 is provided on the lower end surface of the second connector 322, with one end of the connecting groove 3221 forming an opening on the side of the second connector 322. The lower end of the sixth connecting hole is located within the connecting groove 3221. When the second connector 322 is rotated so that the sixth connecting hole is directly below the second feed pipe 3211 (i.e., the predetermined position of the second connector 322), the upper end of the first feed pipe 331 enters the connecting groove 3221 through one end opening, so that the first feed pipe 331 is directly below the sixth connecting hole. That is, the upper end of the sixth connecting hole is connected to the lower end of the second feed pipe 3211, and the lower end of the sixth connecting hole is connected to the upper end of the first feed pipe 331. By rotating the second connector 322, the second connector 322 can be offset and separated from the first feed pipe 331 and the second feed pipe 3211, thereby providing space for the feeding mechanism 33 to move upward, thus providing space for disassembly and assembly of the feeding mechanism 33.

[0114] like Figure 4As shown, the positioning member 323 is fixedly installed on the first frame 1. Specifically, the positioning member 323 is positioned such that when the second connecting member 322 rotates to a predetermined position, the positioning member 323 abuts against the second connecting member 322, preventing the second connecting member 322 from continuing to rotate in that direction, thus achieving positioning of the second connecting member 322. The positioning member 323 is a magnetic component used to attract the second connecting member 322. Therefore, when the second connecting member 322 rotates to a position close to the positioning member 323, it can be attracted and moved to the predetermined position, facilitating the connection between the first feed pipe 331 and the sixth connecting hole. The first hand-tightening bolt 324 is installed on the side of the second connecting member 322 and is threadedly connected to it. By rotating the first hand-tightening bolt 324, its end can be driven into the connecting groove 3221, abutting against the upper end of the first feed pipe 331 within the connecting groove 3221, thereby achieving a fixed connection between the first feed pipe 331 and the second connecting member 322.

[0115] Figure 8 This is a three-dimensional structural diagram of the feeding mechanism 33; Figure 9 This is a cross-sectional view of the feeding mechanism 33. Figure 8 , Figure 9 As shown, the feeding mechanism 33 includes a first feeding pipe 331, a storage component 332, a third stop component 333, a third drive cylinder 334, and a first sensor 335. The first feeding pipe 331 is vertically arranged, with its upper end detachably connected to a second connecting component 322 via a metal connector, and its lower end fixedly mounted on the storage component 332. Thus, after the rivets conveyed by the conveyor belt 311 fall from the end of the conveyor belt 311, they can enter the first feeding pipe 331 through its upper end with the assistance of the connecting component, and then enter the storage component 332 through its lower end.

[0116] like Figure 8 , Figure 9As shown, a vertically arranged through-hole-shaped storage channel 3321 is provided in the storage component 332, which communicates with the lower end of the first feeding pipe 331. The rivets output from the first feeding pipe 331 fall into the storage channel 3321. The third stop 333 is disposed on the storage component 332, located on one side of the storage component 332, and extends radially into the storage channel 3321 from the outside of the storage component 332. The third drive cylinder 334 is fixed on the first frame 1 and disposed on one side of the storage component 332. The drive shaft of the third drive cylinder 334 and the third stop 333 are on the same radial direction of the storage channel 3321 and are engaged with the third stop 333. The first sensor 335 is a laser sensor, fixed on the bracket, and located on the other side of the storage component 332. The storage component 332 has a through hole radially arranged along the storage channel 3321 at the position corresponding to the first sensor 335, connecting to the storage channel 3321. A laser can be used to detect whether there are rivets inside the storage channel 3321. An indicator light is provided on the first sensor 335. When there are rivets in the storage channel 3321, the indicator light on the first sensor 335 is red; when there are no rivets in the storage channel 3321, the indicator light on the first sensor 335 is green.

[0117] like Figure 8 , Figure 9 As shown, four storage units 332 are provided, stacked vertically and connected sequentially. The storage units 332 are fixedly connected to each other, and the storage channels 3321 are arranged and connected sequentially vertically. The uppermost storage unit 332 is fixedly connected to the first feed pipe 331, and the lowermost storage unit 332 is detachably connected to the first frame 1 via a second hand-tightening bolt 336, allowing the storage channel 3321 to connect with the loading / unloading device 5.

[0118] According to the feeding rhythm of the feeding mechanism 31, the number of rivets on the conveyor belt 311 behind the cleaning machine 313 is less than or equal to 4. By setting 4 storage components 332, when rivet jamming or blockage occurs, the cleaning machine 313 can remove the rivets on the conveyor belt 311 located in front of the cleaning machine 313, and the storage components 332 can store the rivets on the conveyor belt 311 located behind the cleaning machine 313, thereby reducing the possibility of rivet jamming or blockage.

[0119] Correspondingly, four third stop members 333, third drive cylinders 334, and first sensors 335 are provided, arranged vertically, and corresponding one-to-one with the storage members 332. That is, each third drive cylinder 334 controls its corresponding third stop member 333 individually, and each first sensor 335 detects whether there are rivets in the corresponding storage member 332.

[0120] During operation, rivets output from the rivet vibratory feeder 21 fall onto the conveyor belt 311 and are transported by the conveyor belt 311. During the rivet transport process, a laser switch detects and counts the rivets, and a CCD camera 312 photographs and identifies them. When a rivet's specifications are detected to be inconsistent with the set specifications, a rivet cleaner 313 removes the non-conforming rivet from the conveyor belt 311. When a rivet's orientation is detected to be incorrect, a steering station 314 rotates the rivet 180° to correct its direction.

[0121] After the rivet moves to the end of the conveyor belt 311, it falls off the conveyor belt 311 and passes through the second feed pipe 3211, the sixth connecting hole, and the first feed pipe 331 into the storage channel 3321 of the storage unit 332. It remains in the storage channel 3321 of the storage unit 332 under the obstruction of the third stop 333. When the first sensor 335 corresponding to the storage unit 332 below the storage unit 332 detects that there is no rivet in the storage channel 3321 of the lower storage unit 332, the third drive cylinder 334 corresponding to the upper storage unit 332 drives the third stop 333 to be pulled out of the storage channel 3321, causing the rivet to fall into the storage channel 3321 of the lower storage unit 332. Then, after a delay of 0.5 seconds, the third drive cylinder 334 drives the third stop 333 to reset, causing the third stop 333 to extend into the storage channel 3321. Thus, the rivets can be moved from top to bottom into the storage channel 3321 of the lowest storage component 332. When the subsequent rivet loading and unloading device 5 needs rivets (when the fifth drive cylinder 544 drives the first slider to slide, so that the first connecting hole 5431 is connected to the second connecting hole 5421 and the fourth connecting hole 5412), the third drive cylinder 334 corresponding to the lowest storage component 332 controls the third stop component 333 to be pulled out from the storage channel 3321, so that the rivets are delivered to the rivet loading and unloading device 5.

[0122] When the first sensor 335 corresponding to the lowest storage unit 332 remains red for more than 1 second, it means that the first sensor 335 has detected that the rivet has remained in the storage channel 3321 of the storage unit 332 for more than 1 second. Therefore, it can be determined that a rivet jamming fault has occurred in the rivet loading / unloading device 5. When the third stop 333 in the lowest storage unit 332 is pulled out of the storage channel 3321, the rivet has not fallen into the rivet loading / unloading device 5 and remains in the storage channel 3321. At this time, the cleaning machine 313 removes all rivets from the conveyor belt 311 that have reached the corresponding position of the cleaning machine 313, preventing rivets from continuously entering the first feed pipe 331 and causing blockage or jamming.

[0123] When the first sensor 335 corresponding to the uppermost storage unit 332 remains red for more than 1 second, it means that the first sensor 335 has detected that the rivet has been in the storage channel 3321 of the storage unit 332 for more than 1 second. Therefore, it can be determined that because the processing rhythm of the rivet loading / unloading device 5 is slower than the rivet supply rhythm of the rivet feeding device 3, all four storage units 332's storage channels 3321 are filled with rivets, indicating a blockage in the storage channels 3321. At this time, the cleaning machine 313 removes all rivets from the conveyor belt 311 that have reached the corresponding position of the cleaning machine 313, preventing rivets from continuously entering the first feeding pipe 331 and causing blockage or jamming.

[0124] When the specifications of the rivets supplied by the rivet feeding device 3 change, the operator can unlock the upper end of the first feeding tube 331 from the second connecting member 322 by rotating the first hand-tightening bolt 324. Then, the operator can rotate the second connecting member 322 to separate and offset it from the upper end of the first feeding tube 331. Next, the operator can rotate the second hand-tightening bolt 336 to disconnect the storage unit 332 from the first frame 1. Finally, the operator can control the storage unit 332 and the first feeding tube 331 to move upward, thereby disengaging the drive rod of the third drive cylinder 334 from the third stop member 333, thus completing the disassembly of the storage unit 332 and the first feeding tube 331. After selecting the storage component 332 and the first feed pipe 331 corresponding to the rivet, place the new storage component 332 and the first feed pipe 331 in the corresponding positions, so that the drive rod of the third drive cylinder 334 and the third stop component 333 are engaged. Then, turn the second hand-tightening bolt 336 to fix the storage component 332 on the first frame 1. Finally, turn the second connecting component 322 to make it abut against the positioning component 323, and turn the first hand-tightening bolt 324 to fix the second connecting component 322 to the upper end of the first feed pipe 331.

[0125] Figure 10 This is a three-dimensional structural diagram of the nail loading and unloading device 5; Figure 11 for Figure 10 A three-dimensional structural diagram of part of the loading and unloading nail device 5; Figure 12 for Figure 10 A side view of the loading and unloading device 5. (See attached diagram.) Figures 10-12As shown, the loading and unloading device 5 includes a first mounting plate 51, a second mounting plate 52, a fourth drive cylinder 53, and a loading and unloading mechanism 54. The first mounting plate 51 is horizontally fixedly mounted on the first frame 1, and the second mounting plate 52 is horizontally positioned above the first mounting plate 51 and slidably connected to it. The fourth drive cylinder 53 is fixedly mounted on the first mounting plate 51, and its drive rod is fixedly connected to the second mounting plate 52, driving the second mounting plate 52 to slide on the first mounting plate 51. Three sets of loading and unloading mechanisms 54 are fixedly mounted on the second mounting plate 52 and arranged along the sliding direction of the second mounting plate 52. The three-assembly and unloading mechanism 54 is adapted to rivets and spacers of different specifications. The fourth drive cylinder 53 drives the second mounting plate 52 to slide, thereby driving the loading and unloading mechanism 54 to move. One of the three-assembly and unloading mechanisms 54 is connected to the rivet feeding device 3 and the spacer feeding pipe 4. The corresponding loading and unloading mechanism 54 can be switched according to the specifications of the rivets and spacers, so that the loading and unloading process is smoother and the possibility of rivet jamming is reduced.

[0126] Figure 13 This is a three-dimensional structural diagram of the loading and unloading mechanism 54; Figure 14 This is a cross-sectional schematic diagram of the loading and unloading mechanism 54. (See attached diagram.) Figure 13 , Figure 14 As shown, the loading / unloading mechanism 54 includes a first mounting block 541, a second mounting block 542, a first slider 543, and a fifth drive cylinder 544. The first mounting block 541 is fixedly mounted on the second mounting plate 52. Two parallel support portions 5411 are provided on the upper surface of the first mounting block 541. The second mounting block 542 is fixedly mounted on the two support portions 5411, forming a rectangular sliding space between the second mounting block 542 and the first mounting block 541. The first slider 543 is a rectangular block-shaped component disposed within the slider space. The upper surface of the first slider 543 is in contact with the lower surface of the second mounting block 542, and the lower surface of the first slider 543 is in contact with the upper surface of the first mounting block 541. The fifth drive cylinder 544 is drively connected to the first slider 543, driving the first slider 543 to slide between the two support portions 5411.

[0127] like Figure 14As shown, a first connecting hole 5431 is vertically provided on the first slider 543, a second connecting hole 5421 and a third connecting hole 5422 are vertically provided on the second mounting block 542, and a fourth connecting hole 5412 is vertically provided on the first mounting block 541. A fifth drive cylinder 544 drives the first slider 543 to slide, so that when one end of the first slider 543 abuts against a support part 5411, the axis of the first connecting hole 5431 coincides with the second connecting hole 5421 and the fourth connecting hole 5412, meaning the first connecting hole 5431, the second connecting hole 5421, and the fourth connecting hole 5412 are connected. The fifth drive cylinder 544 drives the first slider 543 to slide, so that when the other end of the first slider 543 abuts against another support part 5411, the axis of the first connecting hole 5431 coincides with the third connecting hole 5422, meaning the first connecting hole 5431 and the third connecting hole 5422 are connected.

[0128] like Figure 13 , Figure 14 As shown, the loading and unloading mechanism 54 also includes a second slider 545, a sixth drive cylinder 546, and a loading and unloading channel 547. The second slider 545 is mounted on the lower surface of the first mounting block 541 and is slidably connected to it. Two fifth connecting holes 5451 are vertically arranged on the second slider 545, and a vertical loading and unloading channel 547 is fixedly installed at the lower end of each fifth connecting hole 5451. The sixth drive cylinder 546 is drively connected to the second slider 545, driving the second slider 545 to slide, causing one of the two fifth connecting holes 5451 to coincide with and connect to the axis of the fourth connecting hole 5412.

[0129] like Figure 14 As shown, the first mounting block 541 is also provided with two air inlets 5413. The air inlets 5413 are connected to the integrated air circuit unit and can obtain high-pressure air from the integrated air circuit unit. The positions of the air inlets 5413 are configured such that when the sixth drive cylinder 546 drives the second slider 545 to slide, so that the first group of fifth connecting holes 5451 and loading / unloading channels 547 are connected to the fourth connecting hole 5412, the second group of fifth connecting holes 5451 and loading / unloading channels 547 are connected to one air inlet 5413. When the sixth drive cylinder 546 drives the second slider 545 to slide, so that the second group of fifth connecting holes 5451 and loading / unloading channels 547 are connected to the fourth connecting hole 5412, the first group of fifth connecting holes 5451 and loading / unloading channels 547 are connected to the other air inlet 5413.

[0130] As described above, the fifth drive cylinder 544 drives the first slider 543 to slide, so that the first connecting hole 5431 connects with the second connecting hole 5421 and the fourth connecting hole 5412. Then, the rivets provided by the rivet feeding device 3 (rivets falling from the storage component 332 at the lowest end) can sequentially pass through the second connecting hole 5421, the first connecting hole 5431, the fourth connecting hole 5412, and the fifth connecting hole 5451 into the loading and unloading channel 547. Then, the fifth drive cylinder 544 drives the first slider 543 to slide, so that the first connecting hole 5431 connects with the third connecting hole 5422. Then, the spacer blocks provided by the spacer block feeding pipe 4 can enter the first connecting hole 5431 through the third connecting hole 5422. Finally, the fifth drive cylinder 544 drives the first slider 543 to slide, causing the first connecting hole 5431 to reconnect with the second connecting hole 5421 and the fourth connecting hole 5412, thereby allowing the spacer block to enter the corresponding loading and unloading channel 547 through the fourth connecting hole 5412 and the fifth connecting hole 5451. This allows rivets and spacers to alternately enter the loading and unloading channel 547 in a "rivet-spacer-rivet-spacer" sequence, with an assembly cycle of 2-2.5 seconds per group. Furthermore, when the number of rivets and spacers in a loading and unloading channel 547 reaches a predetermined value, the sixth drive cylinder 546 drives the second slider 545 to slide, connecting the fourth connecting hole 5412 with another fifth connecting hole 5451 and the loading and unloading channel 547. Simultaneously, the full loading and unloading channel 547 connects with the air blowing port 5413, using high-pressure air to blow the rivets and spacers in the loading and unloading channel 547 to the boxing device 7. Therefore, during the process of conveying the rivets and spacers in the loading and unloading channel 547 to the boxing device 7, another loading and unloading channel 547 can be used to alternately accommodate and assemble the rivets and spacers, thereby improving the production rhythm and production efficiency.

[0131] Figure 15 One of the three-dimensional structural schematic diagrams of the rivet loading and unloading channel switching device 6; Figure 16 The second three-dimensional structural schematic diagram of the rivet loading and unloading channel switching device 6; Figure 17 One of the schematic diagrams of the orthographic projection structure of the rivet loading and unloading channel switching device 6; Figure 18 The second schematic diagram of the orthographic projection structure of the rivet loading and unloading channel switching device 6; Figure 19 This is the third schematic diagram of the orthographic projection of the rivet loading / unloading channel switching device 6. The rivet loading / unloading channel switching device 6 is fixedly mounted on the first frame 1, located below the rivet loading / unloading device 5. Figures 15-19As shown, the rivet loading / unloading channel switching device 6 includes a first connecting plate 61, a second connecting plate 62, a third connecting plate 63, a connecting pipe 64, a first drive cylinder 65, a second drive cylinder 66, an inlet pipe 67, and a first cleaning pipe 68. The first connecting plate 61, second connecting plate 62, and third connecting plate 63 are rectangular plate-shaped components. The first connecting plate 61 is vertically fixed on the first frame 1, the second connecting plate 62 is mounted on the first connecting plate 61, and the third connecting plate 63 is mounted on the second connecting plate 62. Specifically, the second connecting plate 62 is attached to one side surface of the first connecting plate 61 and is slidably connected to the first connecting plate 61 in the vertical direction. The first drive cylinder 65 is fixedly mounted on the first connecting plate 61 and is drively connected to the second connecting plate 62, driving the second connecting plate 62 to slide in the vertical direction. The third connecting plate 63 is attached to the side surface of the second connecting plate 62 away from the first connecting plate 61 and is slidably connected to the second connecting plate 62 in the horizontal direction. The second drive cylinder 66 is fixedly installed on the first connecting plate 61 and is connected to the third connecting plate 63 in a transmission manner, driving the third connecting plate 63 to slide in the horizontal direction.

[0132] like Figure 16 As shown, the first connecting plate 61 is provided with a first connecting hole 611 and a third connecting hole 612 in the form of a through hole. The first connecting hole 611 is located on one side of the third connecting hole 612 in the horizontal direction. The first connecting hole 611 is connected to the rivet storage box 72 on one side surface of the first connecting plate 61 through the box inlet pipe 67, and the third connecting hole 612 is connected to the cleaning box on one side surface of the first connecting plate 61 through the first cleaning pipe 68.

[0133] The second connecting plate 62 is provided with a second connecting hole 621 and a fourth connecting hole 622 in the form of through holes. The second connecting hole 621 is located at the position corresponding to the first connecting hole 611, and the fourth connecting hole 622 is located at the position corresponding to the third connecting hole 612. There are two pairs of second connecting holes 621 and fourth connecting holes 622 arranged vertically. The first driving cylinder 65 drives the second connecting plate 62 to slide vertically, thereby allowing one of the two pairs of second connecting holes 621 to communicate with the first connecting hole 611, and also allowing one of the two pairs of fourth connecting holes 622 to communicate with the third connecting hole 612.

[0134] like Figure 15As shown, the third connecting plate 63 is provided with a through-hole-shaped fifth connecting hole 631. Two fifth connecting holes 631 are arranged in pairs, each connected to one of the two loading / unloading channels 547 in a loading / unloading mechanism 54 via a connecting pipe 64. The two fifth connecting holes 631 are arranged vertically, corresponding to the two second connecting holes 621 and the two fourth connecting holes 622. The second drive cylinder 66 drives the third connecting plate 63 to slide horizontally, allowing the two fifth connecting holes 631 to connect to either the two second connecting holes 621 or the two fourth connecting holes 622.

[0135] As described above, the second drive cylinder 66 drives the third connecting plate 63 to slide left and right, thereby allowing the fifth connecting hole 631 to switch between connecting with the second connecting hole 621 or the fourth connecting hole 622, and thus switching the connection of the connecting pipe 64 to the box inlet pipe 67 or the first cleaning pipe 68. When the connecting pipe 64 is connected to the box inlet pipe 67, the rivets and spacers in the corresponding loading and unloading channel 547 can be transported to the rivet storage box 72. When the connecting pipe 64 is connected to the first cleaning pipe 68, the rivets and spacers in the corresponding loading and unloading channel 547 can be transported to the cleaning box.

[0136] When the fifth connecting hole 631 is connected to the second connecting hole 621, the second connecting plate 62 is driven to slide up and down by the first driving cylinder 65. This allows one of the two fifth connecting holes 631 to be connected to the second connecting hole 621 and the first connecting hole 611, which means one of the two switching connecting pipes 64 can be connected to the inlet pipe 67. As a result, the loading and unloading channel 547 can be switched, and the rivets and spacers stored in one of the two loading and unloading channels 547 can be blown into the rivet storage box 72.

[0137] When the fifth connecting hole 631 is connected to the fourth connecting hole 622, the second connecting plate 62 is driven to slide up and down by the first driving cylinder 65. This allows one of the two fifth connecting holes 631 to be connected to the fourth connecting hole 622 and the third connecting hole 612, which in turn allows one of the two switching connecting pipes 64 to be connected to the first cleaning pipe 68. As a result, the loading and unloading channel 547 can be switched, and the rivets and spacers stored in one of the two loading and unloading channels 547 can be blown into the cleaning box.

[0138] In addition, the connecting pipe 64 is made of a flexible hose. Since the rivet loading and unloading channel switching device 6 is located below the loading and unloading mechanism 54, and the fifth connecting hole 631 is a horizontal through hole, the connecting pipe 64 will have a bend in the middle. That is, one end of the connecting pipe 64 is connected to the lower end of the loading and unloading channel 547, and the other end extends downward a certain distance before bending towards the fifth connecting hole 631 and extending to connect with the fifth connecting hole 631.

[0139] A valve is installed at the connection point between the connecting pipe 64 and the loading / unloading channel 547. When the valve is closed, the rivets and spacers can be stored in the loading / unloading channel 547. When the valve is open, the rivets and spacers will fall into the connecting pipe 64 under the influence of gravity. Specifically, the rivets and spacers are in an accelerated falling phase before reaching the bending position, and in a sliding phase after turning at the bending position. If the speed of the rivets and spacers is too fast, they will impact the end of the connecting pipe 64, that is, they will rush out of the connecting pipe 64 and rush into the corresponding positions of the first connecting plate 61, the second connecting plate 62, and the third connecting plate 63. At this time, if the first drive cylinder 65 and the second drive cylinder 66 drive the second connecting plate 62 and the first connecting plate 61 to slide and switch, respectively, a jamming failure may occur due to the presence of the rivets and spacers.

[0140] Therefore, in this embodiment, a magnetic suction element 69 is also provided on the connecting pipe 64, forming a magnetic damping mechanism on the connecting pipe 64. The magnetic force of the magnetic suction element 69 keeps the rivet and spacer block between the bend position of the connecting pipe 64 and the fifth connecting hole 631. The magnetic suction element 69 is a ring-shaped component and is detachably connected to the connecting pipe 64. Thus, the position and number of magnetic suction elements 69 on the connecting pipe 64 can be adjusted as needed, thereby adjusting the magnetic attraction force and adsorption effect of the magnetic suction elements 69 on the rivet and spacer block. Specifically, the magnetic suction element 69 is located in the area of ​​the connecting pipe 64 near the bend position, which is the peak point (maximum speed) where the gravitational potential energy of the rivet is converted into kinetic energy. Applying a magnetic field at this point can provide the maximum braking torque. Meanwhile, the magnetic chuck 69 is positioned near the bend in the connecting tube 64, allowing it to be further away from the fifth connecting hole 631. This provides sufficient buffer distance for the rivets and spacers, reducing the magnetic force required and ensuring they remain within the area between the bend and the fifth connecting hole 631. The magnetic force can be adjusted by replacing or increasing the number of magnetic chucks 69, ensuring a suitable level of magnetic force. For example, the magnetic force can be set to three times the weight of the rivet. This prevents the magnetic force from being too weak, which would provide insufficient damping and cause the rivets and spacers to protrude from the connecting tube 64. Conversely, it prevents the magnetic force from being too strong, which could cause them to be stuck at the corresponding position on the magnetic chuck 69, resulting in blockage or jamming.

[0141] like Figures 15-19As shown, since the loading and unloading mechanism 54 is provided with three sets, correspondingly, the first connecting hole 611, the second connecting hole 621, the third connecting hole 612, the fourth connecting hole 622, the fifth connecting hole 631, the connecting pipe 64, the box inlet pipe 67, and the first cleaning pipe 68 are also provided with three sets, each adapted to different specifications of rivets and spacers. Therefore, when the fourth drive cylinder 53 drives the second mounting plate 52 to slide, thereby driving the loading and unloading mechanism 54 to move, one set of the three loading and unloading mechanisms 54 connects to the rivet feeding device 3 and the spacer feeding pipe 4. Thus, when switching the corresponding loading and unloading mechanism 54 according to the specifications of the rivets and spacers, the rivet loading and unloading channel switching device 6 can transport the rivets and spacers through the corresponding specifications of the first connecting hole 611, the second connecting hole 621, the third connecting hole 612, the fourth connecting hole 622, the fifth connecting hole 631, the connecting pipe 64, the box inlet pipe 67, and the first cleaning pipe 68. This makes the conveying process smoother and reduces the possibility of rivet jamming.

[0142] Figure 20 A schematic diagram showing the installation state of the rivet storage box 72 in the rivet mounting area 711; Figure 21 This is a schematic diagram showing the installation state of the rivet storage box 72 in the rivet removal area 712. (See diagram below.) Figure 1 , Figure 2 , Figure 20 , Figure 21 As shown, the boxing device 7 includes a second frame 71, a rivet storage box 72, an inlet port 7373, a first outlet port 74, a second outlet port 75, and a cleaning box 76. The second frame 71 is fixedly installed on one side of the first frame 1, and has a rivet loading area 711 and a rivet unloading area 712. The rivet loading area 711 is used to accommodate and install the rivet storage box 72. The inlet port 7373 is located in the rivet loading area 711, with one end connected to the box inlet pipe 67 and the other end used for plugging and unplugging connection to the inlet connector 722. The first outlet port 74 is located in the rivet loading area 711, at the position corresponding to the outlet connector 723, and is used for plugging and unplugging connection to the outlet connector 723.

[0143] Specifically, the mounting area 711 is equipped with three sets of installation mechanisms that are plugged into and unplugged from the rivet storage boxes 72. This allows the rivet storage boxes 72 to be inserted into the mounting area 711 like a drawer, and then locked and secured by rotating the fastening handle to rotate the cam. When the rivet storage box 72 is inserted into the mounting area 711, the feeding connector 722 is simultaneously inserted into the feeding interface 7373 to receive rivets and spacers delivered by the rivet loading / unloading channel switching device 6, while the discharging connector 723 is simultaneously inserted into the first discharging interface 74. The mounting area 711 has three sets of installation mechanisms, meaning it can accommodate three sets of rivet storage boxes 72, each corresponding to one of the three different specifications of rivets and spacers.

[0144] The rivet removal area 712 is also used to accommodate and install the rivet storage box 72. A second discharge port 75 is located in the rivet removal area 712. One end of the second discharge port 75 is connected to the cleaning box 76 via a second cleaning pipe (not shown), and the other end is used for plug-in connection with the discharge connector 723. Specifically, the rivet removal area 712 is equipped with a mounting mechanism for plug-in connection with the rivet storage box 72. When the rivet storage box 72 is inserted into the rivet loading area 711, the discharge connector 723 is simultaneously inserted into the second discharge port 75, thereby discharging the rivets and spacers from the rivet storage box 72 into the cleaning box 76.

[0145] Figure 22 One of the three-dimensional structural schematic diagrams of the rivet storage box 72; Figure 23 The second schematic diagram of the three-dimensional structure of the rivet storage box 72; Figure 24 This is a cross-sectional view of the rivet storage box 72. Figures 20-24 As shown, the rivet storage box 72 includes a box body 721, an inlet connector 722, an outlet connector 723, a storage tube 724, an air blowing pipe (not shown), and an exhaust valve 725 (not shown). The box body 721 is a rectangular box-shaped component. The inlet connector 722 and the outlet connector 723 are fixedly installed on the same side wall of the box body 721. The storage tube 724 is disposed inside the box body 721, with one end connected to the inlet connector 722 and the other end connected to the outlet connector 723. The middle portion of the storage tube 724 is coiled multiple times to increase its length within the box body 721, thereby accommodating more rivets and spacers.

[0146] like Figure 24 As shown, one end of the feed connector 722 protrudes from the outside of the housing 721 for plugging and unplugging connection with the feed interface 7373 of the mounting area 711, while the other end is located inside the housing 721 for connection with the storage tube 724. The feed connector 722 has a through-hole feed channel 7221 extending along its axis, allowing rivets and spacers to enter the storage tube 724 through the feed channel 7221.

[0147] like Figure 24 As shown, one end of the discharge connector 723 protrudes from the outside of the housing 721 for plugging and unplugging connection with the first discharge interface 74 and the second discharge interface 75, while the other end is inside the housing 721 for connection with the storage tube 724. The discharge connector 723 has a through-hole discharge channel 7231 extending along its axis, through which rivets and spacers can be discharged.

[0148] like Figure 22 As shown, a third air blowing channel 7222 is also provided inside the feed connector 722. One end of the third air blowing channel 7222 is connected to the feed channel 7221, and the other end is located outside the feed connector 722 and inside the box 721 for connection with the air blowing pipeline.

[0149] Figure 25 This is a cross-sectional view of the discharge connector 723. (See diagram below.) Figure 22 , Figure 25 As shown, the discharge connector 723 also includes a first air blowing channel 7232. One end of the first air blowing channel 7232 is located outside the housing 721 and is used to connect to the second air blowing channel inside the second discharge interface 75 after the discharge connector 723 is plugged in and unplugged. The second air blowing channel is used to connect to the air pump of the air circuit unit. The other end of the first air blowing channel 7232 is located inside the housing 721 and is used to connect to the air blowing pipeline. Thus, the second air blowing channel, the first air blowing channel 7232, the air blowing pipeline, the third air blowing channel 7222, and the inlet channel 7221 can be connected, meaning that high-pressure air provided by the air pump can be blown into the inlet channel 7221 through the second air blowing channel, the first air blowing channel 7232, the air blowing pipeline, and the third air blowing channel 7222.

[0150] An exhaust valve 725 is installed on the air blowing pipeline. The exhaust valve 725 includes a first interface 7251, a second interface 7252, and an exhaust port 7253. The first interface 7251 is connected to a third air blowing channel 7222 via the air blowing pipeline, and the second interface 7252 is connected to a first air blowing channel 7232 via the air blowing pipeline. The first interface 7251 is connected to the exhaust port 7253, allowing air to flow unidirectionally from the second interface 7252 to the first interface 7251. Therefore, the exhaust valve 725 can be installed on the air blowing pipeline, allowing it to reuse the air blowing pipeline and connect to the feed channel 7221. Thus, during the process of blowing rivets and spacers into the storage pipe 724 through the feed connector 722 with high-pressure air, the high-pressure gas in the feed channel 7221 can be discharged through the exhaust port 7253 of the exhaust valve 725, thereby reducing the obstruction of material by the reverse flow caused by the high-pressure air being blocked when the material enters the feed channel 7221 and the storage pipe 724. That is, by setting an exhaust valve 725 and connecting it to the feed channel 7221, excess gas in the feed channel 7221 can be discharged, reducing the resistance of material entering the storage pipe 724 from the feed channel 7221. This allows for smoother material loading and improves loading efficiency.

[0151] A cylinder 731 is installed on the inlet 7373 to blow high-pressure air into the inlet channel 7221 of the inlet connector 722, causing the material to move to a position close to the outlet connector 723 of the rivet storage box 72. Specifically, when the rivet loading and unloading device 5 pushes the rivets and spacers into the rivet storage box 72 using high-pressure gas, the distance is too far, and the rivets and spacers do not have enough power to reach the depth of the storage tube 724, that is, they cannot be tightly arranged in the storage tube 724. Therefore, by setting a cylinder on the inlet 7373, after the rivets and spacers enter the inlet channel 7221, the high-pressure air provided by the cylinder can drive the rivets and spacers to move towards the outlet channel 7231 in the storage tube 724, so that the rivets and spacers in the storage tube 724 are arranged more tightly.

[0152] Furthermore, a vacuum generator 76741 is also provided on the first discharge port 74 to draw air from the discharge channel 7231 of the discharge connector 723, so that the rivets and spacers in the storage tube 724 move more smoothly toward the discharge port.

[0153] Figure 26 This is a schematic diagram of the axial orthographic projection of the discharge connector 723. (See attached diagram.) Figure 25 , 26As shown, the discharge connector 723 is also equipped with a first stop 7233 and a second stop 7234. The first stop 7233 and the second stop 7234 extend into / out of the discharge channel 7231 radially. Two first stop 7233 and two second stop 7234 are provided, symmetrically arranged along the diameter of the discharge channel 7231. Viewed axially along the discharge channel 7231, the first stop 7233 and the second stop 7234 are arranged in a cross shape. The axial distance between the first stop 7233 and the second stop 7234 in the discharge channel 7231 is adapted to the length of the material. This allows for convenient and stable control of the material being discharged one by one from the discharge channel 7231, preventing material jamming. This makes the material discharge process smoother, thereby improving the user experience.

[0154] like Figure 21 As shown, the second discharge port 75 is provided with multiple connection ports, which are respectively connected to the air pump. After the discharge connector 723 is connected to the second discharge port 75, high-pressure air is blown into the connection port to control the first stop 7233 and the second stop 7234 to extend into / remove from the discharge channel 7231.

[0155] like Figure 20 , Figure 22 As shown, an information chip 726, such as an RFID chip, is installed on the housing 721. The information chip 726 stores information about the rivets and spacers in the storage tube 724, such as the quantity and specifications of the rivets and spacers. Therefore, when loading rivets and spacers into the rivet storage box 72, this information can be recorded via the information chip 726. When controlling the output of rivets and spacers from the rivet storage box 72, the material information recorded in the information chip 726 can also be used to facilitate the control of the rivet storage box 72. This improves the automation control capability.

[0156] Furthermore, the second cleaning pipe is equipped with a bend, and the material of the second cleaning pipe is softer than that of the material. Therefore, by making the material of the second cleaning pipe softer than the material, damage caused by collisions with the second cleaning pipe can be avoided when the material is transported within the second cleaning pipe under the propulsion of high-pressure air.

[0157] Furthermore, the second cleaning pipe is equipped with a bend, and a buffer is installed within the bend. Thus, when the material moves along the second cleaning pipe under the propulsion of high-pressure air, it will collide with the pipe at the bend. By installing a buffer within the bend, the impact force between the material and the second cleaning pipe can be reduced, preventing damage to the material due to the collision.

[0158] The control device 8 integrates a PLC controller, an HMI human-machine interface, and a pneumatic control module. It is used to receive sensor signals from each unit, control the actions of each actuator, and realize automated control of the work process, parameter setting, and fault alarm.

[0159] The above content provides a detailed description of the specific structure of the automatic aircraft rivet loading system 1000 in this embodiment. The workflow of the automatic aircraft rivet loading system 1000 in this embodiment includes:

[0160] Preparation phase: According to production needs, the operator replaces the rivet pipeline and spacer block pipeline corresponding to the rivet loading and unloading device 5, and sets parameters such as material specifications and assembly quantity through the HMI human-machine interface; puts the rivets and spacers into the corresponding rivet vibratory feeder 21 and spacer block vibratory feeder 22 respectively, and closes the safety door.

[0161] Emptying cycle: After the system starts, the automatic emptying cycle of the rivet box is executed first. Specifically, the rivet storage box 72 is inserted into the rivet unloading area 712, and the residual material in the rivet storage box 72 is blown into the cleaning box by the air blowing function to avoid mixing.

[0162] Feeding and sorting: The vibratory feeding device 2 is activated, and the rivet vibratory feeder 21 disperses and orderly conveys the rivets to the rivet feeding device 3. Incoming materials are detected by a laser switch, and the CCD camera 312 compares the images of the rivets in real time. Materials that do not meet specifications are blown back to the rivet vibratory feeder 21 by the cleaning machine 313. Materials with incorrect orientation are rotated and corrected by the turning station 314. Materials that meet the requirements continue to be conveyed to the rivet feeding device 3, which then conveys them one by one to the rivet loading and unloading device 5. Simultaneously, the spacer vibratory feeder 22 disperses and orderly conveys the spacers to the spacer supply pipe 4, which then conveys them to the rivet loading and unloading device 5.

[0163] Assembly: Rivets and spacers enter the rivet loading / unloading device 5 respectively. The rivet loading / unloading device 5 controls the rivets and spacers to alternately enter the loading / unloading channel 547 in the order of "rivet-spacer-rivet-spacer". The two loading / unloading channels 547 operate alternately. When one loading / unloading channel 547 is completed, it switches to the other loading / unloading channel 547 to continue the operation. At the same time, the assembled material is blown into the rivet storage box 72 of the rivet loading area 711 of the boxing device 7.

[0164] Cleaning Stage: After the operation is completed, the residual material in the rivet vibratory plate 21 and the spacer vibratory plate 22 is manually cleaned into the receiving box. The cleaning function of the rivet box is activated by manually activating the valve to clean the remaining rivets and spacers in the rivet feeding device 3, the rivet loading and unloading device 5, and the rivet loading and unloading channel switching device 6. At the same time, the rivet storage box 72 is inserted into the rivet unloading area 712, and the rivets and spacers in the rivet storage box 72 are blown into the cleaning box 76 by high-pressure air.
