Description

Technical Field

[0001] This invention relates to the field of riveting automation technology, specifically an automatic feeding riveting device. Background Technology

[0002] A rivet is a nail-shaped object with a cap at one end. In riveting, it uses its own deformation or interference fit to connect the riveted parts.

[0003] An automatic feeding riveting device is a piece of equipment used to automate riveting operations. It can automatically feed and load rivets into the rivet gun nozzle to complete the riveting work, effectively improving production efficiency and reducing labor costs.

[0004] Most automatic feeding riveting devices typically rely on machines to automatically arrange and separate rivets, and use compressed air as power to automatically transport the rivets through pipes to the rivet gun nozzle, where the rivet gun completes the riveting action. They are widely used in industries such as chassis, cabinets, lighting fixtures, automobiles, ships, airplanes, small household appliances, servers, electric ovens, microwave ovens, and liquor packaging.

[0005] Upon investigation, the invention patent disclosed a high-speed intelligent rivet gun automatic rivet feeding and automatic riveting device (publication number: CN104550620B), which provides a high-speed intelligent rivet gun automatic rivet feeding and automatic riveting device, a rivet feeding device and an automatic rivet feeding and riveting device connected to the rivet feeding device. The rivet feeding device includes a feeding unit, a conveying unit, a pushing unit and a loading unit. The automatic rivet feeding and riveting device includes a base, a riveting mechanism, a feeding mechanism and a loading mechanism. The rivet feeding device is responsible for feeding rivets, and the automatic rivet feeding and riveting device is responsible for receiving rivets and riveting them.

[0006] Although the aforementioned patent achieves fully automated nail sorting, nail feeding, material handling, and riveting through the design of a nail feeding device and an automatic nail feeding and riveting device connected to the nail feeding device, resulting in a high degree of automation, greatly reducing labor intensity and improving production efficiency, when riveting with a rivet gun, the fixed diameter of the rivet gun nozzle prevents the rivet gun from being adjusted according to different rivet requirements. Furthermore, the air compressor power of the rivet gun cannot be automatically adjusted according to the rivet gun diameter, which may prevent the rivet gun from performing riveting operations and affect the riveting processing of materials.

[0007] Therefore, the present invention provides an automatic feeding and riveting device to solve the above problems. Summary of the Invention

[0011] As a preferred technical solution of this application, the reset mechanism includes a hollow tube fixedly connected to one side of the irregularly shaped box, a reset spring fixedly connected inside the hollow tube, a movable rod slidably connected to one end of the reset spring, one end of the movable rod fixedly connected to a pressing block, and a fixing plate fixedly connected to the upper surface of the irregularly shaped box.

[0012] As a preferred technical solution of this application, the reset mechanism further includes a plurality of guide boxes respectively fixedly connected to the surface of the arc plate. A spring assembly fixedly connected to the connecting frame is fixedly connected inside the guide box. A guide rod fixedly connected inside the guide box is sleeved inside the spring assembly. The connecting frame is slidably connected inside the guide box and sleeved on the surface of the guide rod.

[0013] As a preferred technical solution of this application, the conveying mechanism includes a feed pipe fixedly connected to one side of the surface of the vibratory plate, a conveying track fixedly connected to one end of the feed pipe, an air inlet pipe connected to the conveying track fixedly connected to the surface of the conveying track, an air pump fixedly connected to the vibratory plate fixedly connected to the surface of the air inlet pipe, and a miniature pipe fixedly connected to the surface of the output end of the air pump.

[0014] As a preferred technical solution of this application, the conveying mechanism further includes a nail feeding pipe fixedly connected to one end of the conveying track via a flange. One end of the nail feeding pipe is fixedly connected to a connector that is slidably connected to the working platform. One side of the connector is fixedly connected to a rivet gun nozzle that communicates with the nail feeding pipe. The shaped box is fixedly connected to the rivet gun nozzle. An air supply pipe is fixedly connected through the shaped box on the surface of the rivet gun nozzle. One end of the air supply pipe is fixedly connected to an air compressor.

[0015] As a preferred technical solution of this application, the conveying mechanism further includes a cleaning pipe fixedly connected to the surface of the air compressor and communicating with the air compressor. One end of the cleaning pipe is fixedly connected to the rivet gun nozzle. A pressure pipe communicating with the rivet gun nozzle is fixedly connected to the surface of the air compressor. The linkage plate is slidably connected to the pressure pipe. A fixing frame fixedly connected to the connector is fixedly connected to the surface of the air compressor.

[0016] As a preferred technical solution of this application, a discharge pipe is fixedly connected to the surface of the nail feeding pipe, and a collection box is fixedly connected to one end of the discharge pipe by bolts. A support plate fixedly connected to the working platform is fixedly connected to the lower surface of the collection box, and an air pump with its input end connected to the collection box is fixedly connected to the upper surface of the support plate.

[0017] As a preferred technical solution of this application, the connector has a threaded rod internally connected to it, one end of which is fixedly connected to a drive motor that is fixedly connected to the work platform. The connector is slidably connected to the upper surface of the work platform based on the threaded rod, and the surface of the fixed frame is provided with a sliding groove corresponding to the linkage plate.

[0018] The present invention has the following advantages:

[0019] Based on the cooperation of the adjustment mechanism and the conveying mechanism, the rivet is automatically fed by the cooperation of the vibratory plate, the conveying track and the air pump, so that the rivet enters the rivet gun nozzle. The rivet gun nozzle is used to rivet the material. The rivet is limited by sliding on the surface of the connecting pipe through the arc plate and the connecting frame. When the rivet is aligned with the material, the rivet is riveted into the material by the rivet gun nozzle, so that the same rivet gun nozzle can be used for different diameters.

[0020] When the curved plate slides, the linkage plate drives the sliding plate and the clamping block to slide inside the irregular box. Due to the special shape of the irregular box, the clamping block squeezes or moves away from the air supply pipe, changing the air flow speed and flow volume of the air supply pipe. This allows the air supply pipe to adjust the compressed air entering the air supply pipe according to the diameter and size of the rivet, so that the power of the air compressor matches the rivet model. This avoids applying too much force due to a small rivet model, which would affect the rivet and the material, or applying too little force due to a large rivet model, which would prevent the rivet from achieving the effect of riveting into the material.

[0021] Based on the coordinated structure of air pump, micro-pipe, cleaning pipe and discharge pipe, during the rivet feeding process, the air pump is activated to send compressed air into the rivet feeding pipe through the micro-pipe. This not only provides power to the rivet, enabling it to move inside the rivet feeding pipe, but also cleans up debris inside the rivet feeding pipe. At the same time, based on the coordinated structure of the cleaning pipe and discharge pipe, different positions inside the rivet feeding pipe and connecting pipe are cleaned to prevent debris from affecting the rivet feeding and causing the rivet to get stuck in the automatic feeding and riveting device, thus affecting the automatic riveting of the rivet.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an automatic feeding and riveting device, such as... Figures 1-8 As shown, the automatic feeding and riveting device includes a working platform 1 and support legs fixedly connected to the four corners of the lower surface of the working platform 1. A vibratory feeder 2 is fixedly connected to one side of the upper surface of the working platform 1. A conveying mechanism is installed on one side of the vibratory feeder 2. The conveying mechanism includes a feed pipe 16 fixedly connected to one side of the surface of the vibratory feeder 2. A conveying track 17 is fixedly connected to one end of the feed pipe 16. An air inlet pipe 18 connected to the conveying track 17 is fixedly connected to the surface of the conveying track 17. An air pump 19 fixedly connected to the vibratory feeder 2 is fixedly connected to the surface of the air inlet pipe 18. A micro-pipe 20 is fixedly connected to the surface of the output end of the air pump 19.

[0033] Among them, the vibratory plate 2 is used to neatly arrange and separate the rivets;

[0034] The feed pipe 16 is used to transport the rivets one by one into the conveyor track 17;

[0035] The conveying track 17 is used for conveying and guiding the rivets;

[0036] The air inlet pipe 18 and the air pump 19 are used to provide power to the rivets inside the conveying track 17, so that the rivets can move inside the conveying track 17.

[0037] Among them, the micro-pipe 20 is used to deliver the gas generated by the air pump 19 to the bend of the nail delivery pipe 21, providing power for the debris inside the nail delivery pipe 21, so that the debris moves with the rivet and the debris is cleaned.

[0038] Specifically, rivets are added to the vibratory feeder 2, the rivets are arranged based on the vibratory feeder 2, and the arranged rivets are transported to the inside of the feed pipe 16. The rivets enter the conveying track 17 by the gravity of the rivets and the vibration of the vibratory feeder 2. The air pump 19 is started to compress air and transport it to the conveying track 17 through the air inlet pipe 18 to provide power to the rivets and make the rivets move.

[0039] The conveying mechanism also includes a nail conveying pipe 21 fixedly connected to one end of the conveying track 17 via a flange, and a connector 22 that is slidably connected to the working platform 1 is fixedly connected to one end of the nail conveying pipe 21.

[0040] In this process, compressed air is used to transport the rivets in the conveying track 17 into the rivet delivery pipe 21.

[0041] The connector 22 is used to support the nail delivery tube 21, making the nail delivery tube 21 more stable during use;

[0042] The internal thread of the connector 22 is connected to a threaded rod 32. One end of the threaded rod 32 is fixedly connected to a drive motor 33 that is fixedly connected to the work platform 1. The connector 22 is slidably connected to the upper surface of the work platform 1 based on the threaded rod 32.

[0043] Specifically, the drive motor 33 and the threaded rod 32 cooperate with each other to drive the connecting piece 22 to slide on the working platform 1, and adjust the position of the rivet gun nozzle 23 so that the rivet gun nozzle 23 can perform rivet insertion operations on the material at different positions.

[0044] The surface of the fixed frame 27 is provided with a sliding groove corresponding to the linkage plate 6. One side of the connector 22 is fixedly connected to a rivet nozzle 23 that communicates with the rivet tube 21. The irregular box 10 is fixedly connected to the rivet nozzle 23. The surface of the rivet nozzle 23 passes through the irregular box 10 and is fixedly connected to an air supply pipe 34. One end of the air supply pipe 34 is fixedly connected to an air compressor 24.

[0045] The sliding groove is used to provide space for the linkage plate 6 to slide.

[0046] Among them, the rivet nozzle 23 is used to provide power to the rivet so that the rivet can be driven into the material;

[0047] Among them, the air supply pipe 34 and the air compressor 24 are used to provide power to the rivet gun nozzle 23, so that the rivet gun nozzle 23 can drive the rivet to move.

[0048] Specifically, after the rivet is fed into the rivet gun nozzle 23 through the connector 22 via the rivet feed pipe 21, the air compressor 24 is started, and the compressed air generated by it provides sufficient power to the rivet through the air supply pipe 34, so that the rivet is driven into the material. According to the position of the rivet, the drive motor 33 is started, and its output end drives the threaded rod 32 to rotate, thereby moving the connector 22 to the required position.

[0049] The conveying mechanism also includes a cleaning pipe 25 fixedly connected to the surface of the air compressor 24 and communicating with the air compressor 24. One end of the cleaning pipe 25 is fixedly connected to the rivet gun nozzle 23. A pressure pipe 26 communicating with the rivet gun nozzle 23 is fixedly connected to the surface of the air compressor 24. The linkage plate 6 is slidably connected to the pressure pipe 26. A fixing bracket 27 fixedly connected to the connector 22 is fixedly connected to the surface of the air compressor 24.

[0050] Among them, the cleaning pipe 25 and the pressurizing pipe 26 are used to transmit compressed air generated by the air compressor 24;

[0051] The mounting bracket 27 is used to connect the air compressor 24 and the connector 22;

[0052] Specifically, after the air compressor 24 is started, the compressed air it generates enters the air supply pipe 34 to provide power for the rivet, and at the same time enters the cleaning pipe 25 to provide power for the debris in the rivet gun nozzle 23, so that the debris can be discharged with the rivet, and at the same time enters the pressurization pipe 26 to increase the power intensity in the rivet gun nozzle 23 and avoid insufficient power for the rivet.

[0053] An adjustment mechanism is installed on the surface of the conveying mechanism. The adjustment mechanism includes a connecting pipe 3 installed on the surface of the conveying mechanism. An arc plate 4 is slidably connected to the lower surface of the connecting pipe 3 in a ring array. A connecting frame 5 is fixedly connected to the surface of the arc plate 4.

[0054] Among them, the arc plate 4 is slidably connected to the surface of the connecting pipe 3, so that when the rivet enters the arc plate 4 through the connecting pipe 3, the arc plate 4 can limit the rivet and prevent the rivet from falling freely. Moreover, through the slidable connection of the arc plate 4, the arc plate 4 can limit the rivet of different types, so that the rivet gun nozzle 23 can be used for different types of rivets.

[0055] Among them, the connecting frame 5 is used to limit and guide the arc plate 4;

[0056] Specifically, after the rivet moves into the interior of the arc plate 4 through the rivet gun nozzle 23 and the connecting pipe 3, the arc plate 4 limits the rivet. When the rivet gun nozzle 23 and the connecting pipe 3 move to the required position, the air compressor 24 and the air supply pipe 34 provide power to the rivet, so that the arc plate 4 slides on the connecting pipe 3 and no longer limits the rivet, so that the rivet is riveted into the material.

[0057] The reset mechanism also includes several guide boxes 14 that are fixedly connected to the surface of the arc plate 4. A spring assembly 15 that is fixedly connected to the connecting frame 5 is fixedly connected inside the guide box 14. A guide rod that is fixedly connected to the inside of the guide box 14 is sleeved inside the spring assembly 15. The connecting frame 5 is slidably connected to the inside of the guide box 14 and sleeved on the surface of the guide rod.

[0058] The guide box 14 is used to install the spring assembly 15;

[0059] The spring assembly 15 is used for the automatic reset of the connecting frame 5;

[0060] Specifically, after the rivet passes through the arc plate 4 and causes the arc plate 4 to slide, the arc plate 4 automatically resets based on the elastic force of the spring assembly 15, so that the arc plate 4 can continuously limit different rivets, which is suitable for continuous production.

[0061] One of the connecting frames 5 has a linkage plate 6 fixedly connected to its surface, a sliding plate 7 is attached to the surface of the linkage plate 6, a pressing block 8 is fixedly connected to the surface of the sliding plate 7, a limiting rod 9 is fixedly connected to the surface of the pressing block 8, and a shaped box 10 is slidably sleeved on the surface of the limiting rod 9.

[0062] Among them, the linkage plate 6 is used to drive the sliding plate 7 and the clamping block 8 to move;

[0063] The sliding plate 7 and the clamping block 8 slide inside the irregularly shaped box 10;

[0064] Among them, the irregularly shaped box 10, based on its special shape, allows the clamping block 8 to squeeze or release the air supply pipe 34;

[0065] Specifically, depending on the rivet type, the arc plate 4 slides a different distance, thereby causing the arc plate 4 to move the linkage plate 6 to different positions. The linkage plate 6 then moves the sliding plate 7 and the clamping block 8, causing the limiting rod 9 to slide inside the irregular box 10. This causes the clamping block 8 to squeeze or release the air supply pipe 34, allowing the compressed air entering the air supply pipe 34 to be adjusted according to the diameter and size of the rivet. This ensures that the power of the air compressor 24 matches the rivet type, avoiding excessive force applied due to a small rivet type, which could affect the rivet and the material, and excessive force applied due to a large rivet type, which could prevent the rivet from being riveted into the material.

[0066] A reset mechanism is installed on one side of the irregular-shaped box 10. The reset mechanism includes a hollow tube 11 fixedly connected to one side of the irregular-shaped box 10. A reset spring 12 is fixedly connected inside the hollow tube 11. One end of the reset spring 12 is fixedly connected to a moving rod 13 that is slidably connected to the hollow tube 11. One end of the moving rod 13 is fixedly connected to the abutting block 8.

[0067] The hollow tube 11 is used to guide the movement of the moving rod 13;

[0068] Among them, the return spring 12 is used to reset the moving rod 13;

[0069] Among them, the movable rod 13 is used to connect the linkage plate 6;

[0070] Specifically, when the clamping block 8 moves, the moving rod 13 moves and the return spring 12 stretches. Through the cooperation of the moving rod 13 and the limiting rod 9, the clamping block 8 is guided. After the clamping block 8 is used, based on the elasticity of the spring assembly 15 and the return spring 12, the clamping block 8 and the linkage plate 6 are automatically reset, which makes it convenient to adjust the diameter of the air supply pipe 34 according to the rivet model.

[0071] A discharge pipe 28 is fixedly connected to the surface of the nail feeding pipe 21. A collection box 29 is fixedly connected to one end of the discharge pipe 28 by bolts. A support plate 30 fixedly connected to the working platform 1 is fixedly connected to the lower surface of the collection box 29. An air pump 31 with its input end connected to the collection box 29 is fixedly connected to the upper surface of the support plate 30.

[0072] Among them, the discharge pipe 28 is used to transport the debris in the nail conveying pipe 21;

[0073] The collection box 29 is used to collect debris;

[0074] The support plate 30 is used to support the collection box 29 and the air pump 31.

[0075] Among them, the air pump 31 is used to create negative pressure inside the collection box 29;

[0076] Specifically, when there are debris inside the rivet delivery pipe 21, the air pump 31 is activated to extract the air from the collection box 29, creating a negative pressure inside the collection box 29. This negative pressure is then used to draw the debris from the inside of the rivet delivery pipe 21 through the discharge pipe 28, actively cleaning the debris and allowing it to enter the collection box 29, thus preventing the debris from affecting the movement of the rivets.

[0077] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
