Description

Technical Field

[0001] This application relates to the technical field of fuse lower bracket processing equipment, and in particular to an automated riveting equipment for fuse lower brackets. Background Technology

[0002] In the field of fuse underbody processing, with the continuous increase in industrial automation demands, improving production efficiency and ensuring product quality have become important goals for industry development. The application of automated processing equipment can effectively reduce manual intervention, lower labor intensity, and simultaneously improve production stability and consistency. A highly efficient automated processing system can organically combine various production stages to achieve continuous and streamlined production, thereby meeting the needs of large-scale production and driving the entire industry towards a higher level of development.

[0003] In the past, traditional methods were often used to address material feeding and riveting issues during the riveting process of the lower support. Material feeding relied heavily on manual operation for placing spring clips, rivets, and the lower support body itself. This method was not only inefficient but also prone to human error, leading to inconsistent product quality. While simple vibratory feeders were sometimes used, they lacked effective solutions for coordinating the feeding of multiple materials and for addressing issues such as posture adjustment and positioning during the feeding process. In the riveting process, independent equipment was typically used, with a lack of effective coordination between different steps, making continuous and automated production difficult.

[0004] Traditional methods for riveting lower supports are difficult to automate, achieve continuous, and streamlined production. Manual feeding is inefficient and prone to errors, simple vibratory feeders cannot meet the complex feeding requirements of various materials, and the independent operation of each process lacks coordination, resulting in low production efficiency and failing to meet the requirements of large-scale production.

[0015] By adopting the above technical solutions, a complete automated riveting system solution is provided, realizing the full automation, continuity, and process of the lower bracket riveting process. A modular and scalable circular production line is established, realizing the efficient and reliable conversion of the moving workpiece from high-speed continuous conveying to static precise positioning and then back to high-speed conveying. This ensures that each workpiece slot accurately reaches the preset working position, upgrading the moving workpiece into an active, self-locking accompanying fixture, ensuring the positional stability of the spring in the processing flow.

The sliding plate connected by buffer springs in the rotating workstation has a certain degree of flexibility and buffering capacity during riveting. When the upper riveting block is pressed down, the sliding plate can make a slight retraction, which can not only ensure that the riveting pressure is fully applied, but also effectively absorb overshoot, protect the mold and workpiece, improve the stability of riveting quality and the service life of the equipment.

When the second discharge telescopic motor 313 drives the second discharge drive plate 316 to slide toward the second outlet slide 303 and the second discharge drive plate 316 abuts against the second discharge guide block 312, the second discharge push block 314 pushes the mobile station component 4 located in the second outlet slide 303 to slide toward the conveyor belt group 2.

[0040] The second station detection component 6 includes a second photosensitive detection component 603 installed on the side wall of the second inlet slide 301. When the moving station component 4 on the conveyor belt group 2 enters the second inlet slide 301 and blocks the second photosensitive detection component 603, the second photosensitive detection component 603 sends an electrical signal to the second feeding telescopic motor 305, so that the second feeding telescopic motor 305, the second inflation device 310, the second vacuum device 311, and the second discharge telescopic motor 313 start working successively, with a time interval between the four to ensure that the second unloading mechanism can complete the predetermined operation.

[0041] Reference Figure 1 , Figure 5 , Figure 6 The third docking platform includes a third inlet slide 301, a third docking slide 302, and a third outlet slide 303. The third inlet slide 301 is vertically positioned relative to the conveyor belt group 2, with its inlet docking with the conveyor belt group 2 and its outlet docking with the inlet of the third docking slide 302. The third docking slide 302 is parallel to the conveyor belt group 2, with its inlet docking with the outlet of the third inlet slide 301 and its outlet docking with the inlet of the third outlet slide 303. The third outlet slide 303 is vertically positioned relative to the conveyor belt group 2, with its inlet docking with the outlet of the third docking slide 302 and its outlet docking with the conveyor belt group 2. Additionally, a third feeding mechanism, a rivet feeding assembly 17, a riveting docking assembly, and a workpiece inspection mechanism 5 are arranged on one side of the third docking slide 302, and perform operations on the corresponding mobile workstation components 4 on the third docking slide 302.

[0042] The workbench 1 is equipped with a third feeding slider 304, a third feeding telescopic motor 305 that drives the third feeding slider 304 to slide, and a third feeding slide rail 306 for the third feeding slider 304 to slide, all located at the third inlet slide 301. The third feeding slide rail 306 is installed below the third inlet slide 301. The third feeding telescopic motor 305 is fixedly mounted on the surface of the third feeding slide rail 306 with screws, and the drive rod of the third feeding telescopic motor 305 is fixedly connected to the third feeding slider 304. Simultaneously, a third slider guide plate 307 is fixedly connected to the surface of the third feeding slide rail 306. The third feeding slider 304 is slidably connected to the third slider guide plate 307, allowing the third feeding telescopic motor 305 to drive the third feeding slider 304 to slide along the third slider guide plate 307.

[0043] A third feeding pusher plate 308 is fixedly connected to the third feeding slider 304 by screws. The third feeding pusher plate 308 is L-shaped, and its vertical part is fixedly connected to the surface of the third feeding slider 304. An opening is provided on the third inlet slide 301 for the horizontal part of the third feeding pusher plate 308 to extend into it. The third feeding telescopic motor 305 can drive the horizontal part of the third feeding pusher plate 308 into the third inlet slide 301, allowing it to push the moving station member 4 located at the opening towards the third docking slide 302. Simultaneously, it can block the entrance of the third inlet slide 301, restricting the moving station member 4 from entering and preventing congestion inside the third inlet slide 301.

[0044] A third pusher cylinder 309 is installed on the workbench 1 at the third docking slide 302. The piston rod of the third pusher cylinder 309 extends into the third docking slide 302 and pushes the moving workpiece 4 in the third docking slide 302 toward the third outlet slide 303, so that the moving workpiece 4 placed near the third outlet slide 303 abuts against the side wall of the third outlet slide 303. In addition, the cylinder body of the third pusher cylinder 309 is connected to a third inflation device 310 and a third vacuum device 311 through pipes. The third inflation device 310 is used to drive the piston rod of the third pusher cylinder 309 to slide. There is an interval between the working time of the third inflation device 310 and the working time of the third degassing device 311. The cooperation between the third inflation device 310 and the third degassing device 311 allows the piston rod of the third pushing cylinder 309 to stay in the third docking slide 302, and makes the flowing station part 4 located in the third docking slide 302 fit tightly, so that the flowing station part 4 can be located in a predetermined position, so that the third feeding mechanism can place the spring piece on the flowing station part 4 corresponding to the position.

[0045] A station unloading cylinder 317 is installed at the intersection of the third docking slide 302 and the third outlet slide 303 on the workbench 1. The drive rod of the station unloading cylinder 317 is fixedly connected to a station unloading block 318, which extends into the outlet of the third docking slide 302.

[0046] The workbench 1 is equipped with a third discharge guide block 312, a third discharge telescopic motor 313, and a third discharge push block 314 at the third outlet slide 303. The third discharge guide block 312 has multiple through sliding grooves, and the third discharge push block 314 is fixedly connected to multiple third sliding rods 315. The number and position of the third sliding rods 315 match the sliding grooves, allowing the third discharge push block 314 to slide against the third discharge guide block 312 via the third sliding rods 315. After the third discharge push block 314 and the third discharge guide block 312 are aligned, their surfaces abut against each other. A third discharge drive plate 316 is fixedly connected to the end of the third sliding rod 315 facing away from the third discharge push block 314. The third discharge drive plate 316 is fixedly connected to the drive rod of the third discharge telescopic motor 313. When the third discharge telescopic motor 313 drives the third discharge drive plate 316 to slide towards the third outlet slide 303, and the third discharge drive plate 316 abuts against the third discharge guide block 312, the third discharge push block 314 pushes the mobile station component 4 located in the third outlet slide 303 to slide towards the conveyor belt group 2.

[0047] The third station inspection component 6 includes a third photosensitive inspection component 604 installed on the side wall of the third inlet slide 301. When the moving station component 4 on the conveyor belt group 2 enters the third inlet slide 301 and blocks the third photosensitive inspection component 604, the third photosensitive inspection component 604 sends an electrical signal to the third feeding telescopic motor 305, so that the third feeding telescopic motor 305, the third inflation device 310, the third vacuum device 311, and the third discharge telescopic motor 313 start working successively, with a time interval between the four to ensure that the third unloading mechanism, the rivet loading assembly 17, the riveting and docking assembly, and the workpiece inspection mechanism 5 can complete the predetermined work.

[0048] Reference Figure 1 , Figure 7 The workpiece inspection mechanism 5 includes a first electric slide 501 fixedly connected to the worktable 1. A detection slide rail 502 is fixedly connected to the first electric slide 501, and a detection electric slider 503 is slidably connected to the detection slide rail 502. A detection frame 504 is fixedly connected to the detection electric slider 503. Three detection protrusions 505 are integrally formed on the detection frame 504, and height detectors are embedded in the detection protrusions 505. The detection electric slider 503 drives the detection protrusions 505 to slide towards the corresponding position of the mobile station component 4, so that the detection protrusions 505 extend into the workpiece groove 404 opened on the mobile station component 4. The height detector monitors the position where the detection protrusions 505 are blocked, thereby determining whether a spring is installed in the workpiece groove 404.

[0049] Reference Figure 1 , Figure 4Conveyor belt group 2 consists of a long conveyor belt 201 and a short conveyor belt 202.

[0050] One end of the long conveyor belt 201 connects to the inlet of the first inlet slide 301, and the other end connects to the outlet of the third outlet slide 303. It is used to receive the mobile workpiece 4 sliding out from the third outlet slide 303 and to feed the mobile workpiece 4 into the first inlet slide 301. Two waiting platforms 203 are provided along the path of the long conveyor belt 201. The upper surface of the waiting platform 203 is flush with the upper surface of the long conveyor belt 201, and its lower surface is fixedly connected to the worktable 1 via a fixing rod. Simultaneously, the width of the waiting platform 203 matches the width of the mobile workpiece 4, allowing the mobile workpiece 4 to slide onto the waiting platform 203 under the drive of the long conveyor belt 201. Only one mobile workpiece 4 slides onto the waiting platform 203 and pushes the mobile workpiece 4 on the waiting platform 203 to continue contacting the long conveyor belt 201. This allows the mobile workpiece 4, originally located on the waiting platform 203, to continue sliding down the long conveyor belt 201, with the next mobile workpiece 4 replacing the previous one and stopping on the waiting platform 203. This ensures that only one mobile workpiece 4 enters the first inlet chute 301 via the long conveyor belt 201 at a time.

[0051] One end of the short conveyor belt 202 connects to the outlet of the first exit chute 303, and the other end connects to the inlet of the third inlet chute 301. Meanwhile, the second inlet chute 301 and the second exit chute 303 are installed at intervals along the path of the short conveyor belt 202, thus cutting the short conveyor belt 202 in the middle. This allows the moving workstation component 4 to slide out of the first exit chute 303, first enter the second inlet chute 301, and then slide out of the second exit chute 303 before entering the third inlet chute 301.

[0052] Reference Figure 1 , Figure 8 The mobile workstation component 4 includes a base 401 and three workpiece support plates 402 fixedly mounted on the base 401 by screws. The three workpiece support plates 402 are evenly arranged along the length of the base 401. Each workpiece support plate 402 is integrally formed by a back plate and two side plates, with the two side plates respectively mounted on both sides of the back plate in the width direction. The three components together form a support groove for supporting the workpiece. In addition, the back plate has an inclined surface above the top surface of the side plates, which abuts against the inclined surface of the spring sheet to provide support for the spring sheet.

[0053] A pressure plate 403 is fixedly connected to the surface of the base 401 by screws. Three workpiece grooves 404 are formed on the pressure plate 403, corresponding to the positions of the workpiece support plate 402. Simultaneously, first clearance grooves are formed on both sides of the workpiece grooves 404 on the pressure plate 403. The side plates supporting the workpiece extend into the first clearance grooves, making the inner walls of the two side plates flush with the inner walls of the corresponding workpiece grooves 404. Furthermore, a first limiting block 405 is integrally formed at the bottom of the workpiece groove 404. The first limiting block 405 cooperates with the pressure plate 403 to form a spring mounting area for installing spring clips.

[0054] The pressure plate 403 has gripping grooves 406 on both sides of the inner wall of each workpiece groove 404, and the gripping grooves 406 are recessed towards the surface of the base 401, creating a height difference between the bottom of the gripping groove 406 and the bottom of the workpiece groove 404. Simultaneously, a groove is formed on the inner wall of the gripping groove 406 near the workpiece groove 404 to facilitate the operation of the spring feeding assembly, the rivet feeding assembly 17, and the riveting assembly within the workpiece groove 404. Furthermore, the base 401 and the pressure plate 403 have positioning holes 407, allowing the rivet feeding assembly 17 to insert rivets into the rivet positioning holes 407 after the spring is passed through.

[0055] Reference Figure 8 , Figure 9 The base 401 has three rotating grooves 408 that correspond to and communicate with the three workpiece grooves 404. The inner wall of each rotating groove 408 is rotatably connected to a rotating shaft, and a snap-fit ​​plate 409 is rotatably connected to the rotating shaft. The snap-fit ​​plate 409 includes an integrally formed sleeve part, a pressing part, and a snap-fit ​​part, and both the pressing part and the snap-fit ​​part rotate about the sleeve part as the center.

[0056] The socket is hollow and is fitted onto the rotating shaft.

[0057] A return spring 410 is fixedly connected to the outer surface of the pressing part, and the end of the return spring 410 away from the pressing part is fixed to the inner wall of the rotating groove 408 by continuous welding.

[0058] The snap-fit ​​part extends into the workpiece groove 404, and a second clearance groove is provided on the snap-fit ​​part. The first limiting block 405 passes through the second clearance groove, so that the ends of the snap-fit ​​part on both sides of the second clearance groove press against the surface of the spring piece, thereby preventing the spring piece from shifting during transportation.

[0059] Reference Figure 5 , Figure 9 The conveyor belt group 2 includes a first limiting slide 204, and the base 401 has a first limiting slide groove 411 at the bottom that cooperates with the first limiting slide 204. The base 401 connects with the first limiting slide 204 through the first limiting slide groove 411, so that the base 401 can slide on the conveyor belt group 2.

[0060] Reference Figure 2 , Figure 8 The first, second, and third feeding mechanisms in the spring sheet feeding assembly each include two arranged flip-feeding groups. Each flip-feeding group consists of a spring sheet vibrating plate 7, a flip-gripping member 8, and a spring sheet feeding robot arm 9. Multiple spring sheets are placed inside the spring sheet vibrating plate 7. The spring sheets are carried by the flip-gripping member 8 at the outlet of the spring sheet vibrating plate 7. After the flip-gripping member 8 aligns the position of the spring sheets, the spring sheet feeding robot arm 9 clamps the spring sheets and places them in the station slot of the corresponding mobile station member 4.

[0061] Reference Figure 1 , Figure 10 , Figure 11 A first fixed frame 10 is fixedly connected to the workbench 1. The first fixed frame 10 has an opening that aligns with the feeding track of the spring vibrating plate 7. The feeding track of the spring vibrating plate 7 passes through the first fixed frame 10, with its opening facing the station circulation assembly. The feeding track of the spring vibrating plate 7 is fixed to the first fixed frame 10 with screws, and the two components form a spring feeding port 1001 for spring feeding. Additionally, a U-shaped block 1002 is screwed to the surface of the first fixed frame 10 facing away from the spring vibrating plate 7. The opening of the U-shaped block 1002 faces the spring feeding port 1001 of the feeding track of the spring vibrating plate 7, and two second infrared detectors 1003 are fixedly connected to the two ends of the U-shaped block 1002. The second infrared detectors 1003 are used to monitor whether a spring has slid out of the spring vibrating plate 7.

[0062] The flip-grip member 8 includes a flip-telescopic motor 801 fixedly connected to the back of the first fixed frame 10. The flip-telescopic motor 801 is connected to the first fixed frame 10 by screws, and a rack 802 is fixedly connected to the end of its drive rod to drive the rack 802 to slide away from or towards the worktable 1. In addition, the first fixed frame 10 is connected to a limiting plate 803 by screws. The limiting plate 803 and the first fixed frame 10 cooperate to form a second limiting slide. At the same time, a limiting protrusion 804 is integrally formed on the side of the rack 802. The limiting protrusion 804 extends into the second limiting slide and slides along the inside of the second limiting slide.

[0063] The first fixed frame 10 is embedded with a bearing, and a rotating rod 805 is inserted through and rotatably connected to the bearing. A gear 806 is fixedly connected to one end of the rotating rod 805 facing the spring vibrating disk 7, and a first mounting frame 807 is fixedly connected to the other end of the rotating rod 805. Furthermore, the gear 806 meshes with the rack 802, so that when the rack 802 slides away from or towards the worktable 1, it can drive the gear 806 to rotate clockwise or counterclockwise, thereby controlling the first mounting frame 807 to rotate 180°.

[0064] An L-shaped support plate 808 is fixedly connected to one side of the first mounting bracket 807. The surface of the L-shaped support plate 808 has negative pressure adsorption grooves 810, and a negative pressure hole 809 is formed in the portion of the L-shaped support plate 808 between the two negative pressure adsorption grooves 810. Simultaneously, the surface portion of the L-shaped support plate 808 at the negative pressure hole 809 is recessed downwards, forming a channel communicating with the negative pressure adsorption grooves 810. A first negative pressure tube 811 passes through the negative pressure hole 809, and the end of the first negative pressure tube 811 is fixedly connected to the L-shaped support plate 808 by screws. The end of the first negative pressure tube 811 facing away from the L-shaped support plate 808 is connected to a first negative pressure device 812, which operates continuously. The L-shaped support plate 808 has an inclined surface that matches the spring piece on the surface opposite to the first mounting bracket 807. The L-shaped support plate 808 is provided with a second limiting block 813. The second limiting block 813 cooperates with the inclined surface, so that one end of the spring piece can abut against the inner wall of the second limiting block 813, and the middle part of the spring piece can lean against the inclined surface.

[0065] A first guide groove 11 is provided on the first mounting bracket 807, with the opening of the first guide groove 11 facing the inclined surface of the L-shaped support plate 808. Additionally, a second electric slide 12 is fixedly connected to the surface of the first mounting bracket 807, and a clamping electric slider 13 is slidably connected to the second electric slide 12. A clamping block 14 is fixedly connected to the clamping electric slider 13, extending into the first guide groove 11. The clamping electric slider 13 can slide on the second electric slide 12, causing the clamping block 14 to slide out of the first guide groove 11 and slide closer to the L-shaped support plate 808. Furthermore, when the clamping block 14 slides into position, it abuts against the surface of the second limiting block 813, and a clamping channel matching the spring feed port 1001 is formed on the surface component of the L-shaped support plate 808, with the side of the clamping channel facing the inclined surface being open.

[0066] When the L-shaped support plate 808 aligns with the feeding track of the spring vibratory plate 7, the surface of the second limiting block 813 faces the worktable 1, connecting the clamping channel with the spring feeding port 1001. At this time, as the spring is removed from the spring feeding port 1001, it enters the clamping channel, its surface abutting against the surface of the clamping block 14 and providing support. Simultaneously, after the spring and clamping channel are in place, the second infrared detector 1003 is triggered, driving the flip-and-telescopic motor 801, the clamping electric slider 13, and the spring feeding robotic arm 9 to work sequentially. The first negative pressure device 812 creates negative pressure on the surface of the spring through the negative pressure hole 809, and simultaneously creates negative pressure at the two negative pressure adsorption grooves 810 through the negative pressure hole 809, thereby adsorbing the spring onto the L-shaped support plate 808. The flip-and-telescopic motor 801 flips the spring, bringing it to its installed position. After the flipping is completed, the clamping electric slider 13 drives the clamping block 14 to retract from the L-shaped support plate 808 into the first guide groove 11, thereby providing sufficient space for the spring sheet unloading robot arm 9. After the clamping block 14 slides into the first guide groove 11, the spring sheet unloading robot arm 9 clamps the spring sheet on the L-shaped support plate 808 and inserts it into the flow station component 4. Furthermore, after the spring sheet unloading robot arm 9 has completed its work, the clamping electric slider 13 and the flipping telescopic motor 801 operate here, causing the clamping channel to reconnect with the spring sheet discharge port 1001 to carry the next spring sheet.

[0067] Reference Figure 1 , Figure 4 , Figure 8 A telescopic motor 15 is fixedly connected to the worktable 1. A mounting block 16 is fixedly connected to the drive rod of the telescopic motor 15. The position of the mounting block 16 corresponds to the moving station component 4 at the working position of the spring sheet unloading robot arm 9. The mounting block 16 is positioned above one of the snap-fit ​​plates 409 of the moving station component 4. Before the spring sheet unloading robot arm 9 operates, the telescopic motor 15 drives the mounting block 16 to press the snap-fit ​​plate 409 and open the workpiece slot 404. After the spring sheet unloading robot arm 9 places the spring sheet into the opened workpiece slot 404, the telescopic motor 15 drives the mounting block 16 to release the snap-fit ​​plate 409 and snap-fit ​​and fix the workpiece slot 404 and the spring sheet in the workpiece slot 404.

[0068] The difference between the first, second, and third feeding mechanisms lies in the different dimensions of the mounting blocks 16. This allows the first feeding mechanism to open the mobile station 4 via its mounting blocks 16, bringing it closer to the workpiece slot 404 of the clamping electric slider 13. The second feeding mechanism can open the middle workpiece slot 404 of the mobile station 4 via its mounting blocks 16. The third feeding mechanism can open the mobile station 4 away from the workpiece slot 404 of the clamping electric slider 13 via its mounting blocks 16. This allows each workpiece slot 404 in the mobile station 4 to hold springs made of three different materials.

[0069] Reference Figure 1 , Figure 12 The rivet feeding assembly 17 includes a rivet vibratory feeder 1701, a rivet unloading robotic arm 1702, and a second fixed frame 1703 fixedly connected to the unloading track of the rivet vibratory feeder 1701. The unloading track of the rivet vibratory feeder 1701 is provided with two rivet unloading ports. An abutment block 1704 is fixedly connected to the surface of the second fixed frame 1703, and one side of the abutment block 1704 is flush with the outlet of the rivet unloading port.

[0070] Reference Figure 1 , Figure 12 , Figure 13 A third electric slide 1705 is fixedly connected to the worktable 1. A rivet electric slider 1706 is slidably connected to the third electric slide 1705, and a second mounting bracket 1707 is fixedly connected to the surface of the rivet electric slider 1706. A mating platform 1708 is fixedly connected to the surface of the second mounting bracket 1707 by screws. The surface of the mating platform 1708 is in contact with the surface of the abutment block 1704, and two rivet slots for engaging rivets are provided on the mating platform 1708. At the same time, the rivet electric slider 1706 drives the second mounting bracket 1707 and the mating platform 1708 to slide along the surface of the abutment block 1704, so as to move the rivet slots closer to or away from the rivet discharge port, and the two rivet slots mate with the two rivet discharge ports one by one. In addition, during the sliding process of the mating platform 1708, the two rivet slots are always located within the projection of the abutment block 1704.

[0071] A second negative pressure device 1709 is fixedly connected to the workbench 1. Two second negative pressure pipes 1710 are connected to the second negative pressure device 1709, and each second negative pressure pipe 1710 is fixedly connected to the docking platform 1708. Each second negative pressure pipe 1710 is in fluid communication with a corresponding rivet groove, and a stable negative pressure is formed in the rivet groove, thereby stably connecting the rivet in the rivet groove to the docking platform 1708.

[0072] The second fixing frame 1703 is fixedly connected to a limiting platform 1711 on its side. A guide rod 1712 is fixedly connected to the limiting platform 1711, and the guide rod 1712 is hollow. The limiting platform 1711 has an opening that is in fluid communication with the inner cavity of the guide rod 1712, allowing one end of the guide rod 1712 to extend into the opening. A flow-limiting block 1713 is fixedly connected to the end of the guide rod 1712, and the periphery of the flow-limiting block 1713 cooperates with the inner wall of the guide rod 1712 to form an airflow channel. A sliding sleeve 1714 is provided on the outside of the guide rod 1712, and the inner cavity of the sliding sleeve 1714 communicates with the inner cavity of the guide rod 1712, closing that end of the guide rod 1712. A top material block 1715 is fixedly connected to the surface of the sliding sleeve 1714, and a top material rod 1716 is fixedly connected to the top material block 1715. The top material rod 1716 extends into the third clearance groove opened on the mating table 1708. Furthermore, when the rivet groove slides away from the rivet discharge port, the top material rod 1716 extends into the third clearance groove, positioning itself below the rivet engaged in the rivet groove. Additionally, a third limiting block is integrally formed on the surface of the sliding sleeve 1714, engaging with the second limiting groove opened on the limiting table 1711, thereby limiting the sliding distance of the sliding sleeve 1714.

[0073] A third negative pressure device 1717 is fixedly connected to the workbench 1. The third negative pressure device 1717 passes through the limiting platform 1711 via a third negative pressure pipe and is fixedly connected to the guide rod 1712, communicating with the inner cavity of the guide rod 1712. This allows the third negative pressure device 1717 to create negative pressure in the inner cavity of the guide rod 1712 and the inner cavity of the sliding sleeve 1714 after it is activated. This causes the sliding sleeve 1714 to slide closer to the limiting platform 1711, thereby causing the ejector rod 1716 to eject the rivet. This facilitates the rivet unloading robot arm 1702 to grab the rivet and place it in the corresponding position of the moving station component 4, allowing the rivet to pass through the spring clip of the moving station component 4. In addition, after the rivet feeding robot arm 1702 finishes its gripping operation, the third negative pressure device 1717 stops working simultaneously, so that outside air can flow into the inner cavity of the guide rod 1712 and the inner cavity of the sliding sleeve 1714 through the airflow channel, so that the air pressure in the inner cavity of the guide rod 1712 and the inner cavity of the sliding sleeve 1714 is balanced with the outside air pressure. Under the weight of the top material block 1715 and its own weight, the sliding sleeve 1714 slides towards the worktable 1, thereby providing installation space for the rivet.

[0074] A rivet feeding cylinder 1718 is fixedly connected to the workbench 1. The piston rod of the rivet feeding cylinder 1718 is fixedly connected to a feeding pressure block 1719. The rivet feeding cylinder 1718 is used to drive the feeding pressure block 1719 to press the snap-fit ​​plate 409 on the moving station part 4 located in the rivet feeding area. This causes the snap-fit ​​plate 409 to disengage from the spring clip and provides working space for the rivet unloading robot arm 1702.

[0075] Reference Figure 14 The lower support loading assembly includes a first lifting platform mechanism, a second lifting platform mechanism, a translation conveying mechanism 26, and multiple lower support placement boxes 27. The lower support placement boxes 27 are initially installed on the first lifting platform mechanism and are transported to the second lifting platform mechanism via the translation conveying mechanism 26. Each lower support placement box 27 contains multiple lower support bodies.

[0076] Reference Figure 14 , Figure 15 Both the first and second lifting platform mechanisms include a housing 18 fixedly connected to the worktable 1. The housing 18 is hollow, and a lifting drive motor 19 is fixedly connected to its top outer surface. The drive rod of the lifting drive motor 19 extends into the housing 18 and is fixedly connected to a threaded rod 20. The threaded rod 20 rotates within the cavity of the housing 18 under the action of the lifting drive motor 19.

[0077] A second guide groove 21 is provided on the side of the housing 18 opposite to the translation conveying mechanism 26. Simultaneously, guide grooves 22 are provided on the outer surfaces of opposite sides of the housing 18. Furthermore, a lifting sleeve 23 is fitted over the threaded rod 20, and the lifting sleeve 23 is threadedly connected to the threaded rod 20. A lifting plate 24 is fixedly connected to the surface of the lifting sleeve 23 via a connecting rod, wherein the connecting rod extends into the second guide groove 21, and the outer wall of the connecting rod abuts against the inner wall of the second guide groove 21. The lifting plate 24 abuts against the outer surface of the housing 18, and a lifting bracket 25 is fixedly connected to the side of the lifting plate 24 opposite to the translation conveying mechanism 26 via screws. The lifting bracket 25 extends into the translation conveying mechanism 26, and a lower support placement box 27 is installed within the lifting bracket 25.

[0078] The lifting bracket 25 includes a connecting support plate 2501, two guide support plates 2502, a mounting support plate 2503, and two bracket support plates 2504. The connecting support plate 2501 is fixedly connected to the connecting rod by screws. A guide support plate 2502 is fixedly connected to each side of the connecting support plate 2501, and a guide protrusion 2505 is integrally formed on each guide support plate 2502, extending into a guide groove 22. The ends of the two guide support plates 2502 are fixedly connected to the mounting support plate 2503. The surface of the mounting support plate 2503 facing away from the guide support plates 2502 is fixedly connected to the two bracket support plates 2504. The two bracket support plates 2504 are respectively installed on both sides below the mounting support plate 2503. A fourth limiting block 2506 is fixedly connected to the upper surface of the bracket support plate 2504. The fourth limiting block 2506 cooperates with the mounting support plate 2503 to fix the position of the lower bracket placement box 27.

[0079] The translational conveying mechanism 26 includes two crossbeams 2601 fixedly connected to the worktable 1. An opening in the worktable 1 between the two crossbeams 2601 is provided for placing the lower support placement box 27. A rotating frame 2602 is fixedly connected to both ends of each crossbeam 2601 and is fixed to the worktable 1 via the rotating frame 2602. Furthermore, a rotating roller 2603 is rotatably connected within each rotating frame 2602, and the two rotating rollers 2603 are connected by a transmission chain 2604. Additionally, a transmission rod 2605 is fixedly connected to one of the rotating rollers 2603 on one of the crossbeams 2601, and this transmission rod 2605 is fixed to a corresponding transmission roller on the other crossbeam 2601. Meanwhile, a translational rotation motor 2606 is fixedly connected to one of the crossbeam plates 2601. The drive rod of the translational rotation motor 2606 is fixed to one of the rotating rollers 2603 on the crossbeam plate 2601, so that the translational rotation motor 2606 can drive the transmission chains 2604 on the two crossbeam plates 2601 to rotate synchronously.

[0080] A translation slide rail is integrally formed on the crossbeam plate 2601. Two translation slide blocks 2607 are slidably connected to the translation slide rail, and the two translation slide blocks 2607 are fixed by a translation frame. A transmission block 2608 is fixedly connected to the side of the translation frame away from the lifting bracket 25. The transmission block 2608 has a transmission groove for the transmission chain 2604 to pass through. The inner wall of the transmission groove is provided with a rack 802 that meshes with the transmission chain 2604, so that the rotation of the transmission chain 2604 can drive the transmission block 2608 and the translation frame to slide.

[0081] Two docking electric telescopic motors 2609 are fixedly connected to the translation frame, and docking blocks 2610 are fixedly connected to the drive rods of the docking electric telescopic motors 2609. A docking groove is provided on the side of the lower support placement box 27 facing the translation frame. The docking electric telescopic motors 2609 can drive the docking blocks 2610 to insert into the docking groove, thereby disengaging the lower support placement box 27 from the lifting bracket 25, thus controlling the lower support placement box 27 to slide along the crossbeam plate 2601. This allows the lower support placement box 27 to move from the first lifting platform mechanism to the second lifting platform mechanism.

[0082] Reference Figure 16 The riveting assembly includes a spring assembly robotic arm 28, a lower support assembly robotic arm 31, a material unloading robotic arm 32, an assembly table 33, and a riveting mechanism 34, all mounted on a workbench 1.

[0083] The spring sheet assembly robot arm 28 is mounted on the worktable 1, and a spring sheet unloading cylinder 29 is fixedly connected to the worktable 1 below it. The piston rod end of the spring sheet unloading cylinder 29 is fixedly connected to the unloading pressure block 30. The spring sheet unloading cylinder 29 is used to drive the unloading pressure block 30 to press the snap-fit ​​plate 409 on the moving station component 4 located in the working area of ​​the spring sheet assembly robot arm 28. This causes the snap-fit ​​plate 409 to disengage from the spring sheet, so that the spring sheet assembly robot arm 28 can grab the spring sheet in the moving station component 4 in the area and put it into the lower support body in the assembly table 33.

[0084] Reference Figure 1 , Figure 16 The lower support assembly robotic arm 31 is installed above the lower support loading assembly. It is used to clamp the lower support body in the lower support placement box 27 and transfer the clamped lower support body to the assembly table 33.

[0085] Assembly table 33 includes a base 3301 and a platform rotation motor fixedly connected to the workbench 1. The drive rod of the platform rotation motor extends into the base 3301 and is connected to the rotating platform 3303. Meanwhile, the rotating platform 3303 is installed above the base 3301 and rotates relative to the base 3301. Furthermore, eight rotating stations are fixedly connected to the rotating platform 3303 by screws.

[0086] Reference Figure 16 , Figure 17 The rotating station includes a Z-shaped mounting plate 3304, one short plate of which is fixedly connected to the surface of the rotating platform 3303 by screws. A guide slide 3305 is fixedly connected to the long plate of the mounting plate 3304 by screws, and an L-shaped sliding plate 3306 is slidably connected to the guide slide 3305. One end of a buffer spring 3307 is fixedly connected to the bottom of the sliding plate 3306, and the other end of the buffer spring 3307 is fixedly connected to the other short plate of the mounting plate 3304. Furthermore, a fifth limiting block 3308 is integrally formed on the guide slide 3305, and a limiting groove is formed on the sliding plate 3306. The fifth limiting block 3308 extends into the limiting groove and, under the action of the buffer spring 3307, abuts against the inner wall of the limiting groove near the worktable 1.

[0087] Reference Figure 17 Four positioning blocks 3309 are integrally formed on the upper surface of the sliding plate 3306. The four positioning blocks 3309 cooperate with the surface of the sliding plate 3306 to form a docking area for installing the lower bracket body. Furthermore, the sliding plate 3306 has a riveting opening 3302 in the aforementioned docking area, so that after the lower bracket body is installed in the docking area, the part of the lower bracket body that needs to be riveted is located within the projection of the riveting opening 3302.

[0088] Reference Figure 16 , Figure 18The riveting mechanism 34 includes a riveting cylinder 3401 fixedly connected to the worktable 1 via a connecting column. A U-shaped upper riveting seat 3402 is fixedly connected to the piston rod of the riveting cylinder 3401, and an upper riveting block 3403 is fixedly connected to the center of the upper riveting seat 3402. Furthermore, a pressure head 34031 and a positioning head 34032 are integrally formed on the upper riveting block 3403, with the positioning head 34032 being longer than the pressure head 34031. The positioning head 34032 can extend into an opening in the lower support body and abuts against the inner wall of the opening to ensure the position of the lower support body. The pressure head 34031 is matched with the position of the rivet installed in the lower support body, allowing the pressure head 34031 to compress the rivet under the drive of the riveting cylinder 3401.

[0089] A U-shaped lower riveting seat 3404, matching the position of the upper riveting seat 3402, is fixedly connected to the worktable 1. This allows the riveting cylinder 3401 to drive the two ends of the upper riveting seat 3402 to abut against the two ends of the lower riveting seat 3404, thereby limiting the displacement length of the riveting cylinder 3401. A lower riveting block 3405 is fixedly connected inside the lower riveting seat 3404. The lower riveting block 3405 is slidably connected to the lower riveting head 3406 via a guide post, and a helical spring connects the lower riveting block 3405 and the lower riveting head 3406. The platform rotation motor drives the rotating platform 3303 to rotate the sliding plate 3306 above the lower riveting block 3405, positioning the lower riveting block 3405 below the rivet in the lower support body. This causes the riveting cylinder 3401 to drive the upper riveting head 34031 to slide closer to the lower riveting head 3406 and squeeze the rivet. Under the combined squeezing of the upper riveting head 34031 and the lower riveting head 3406, the rivet deforms, thereby fixing the spring piece to the lower bracket body.

[0090] Reference Figure 16 The workbench 1 is fixedly connected with multiple unloading slides 35. The unloading robot arm 32 can clamp the riveted lower support body from the rotating station and place it in different unloading slides 35 according to the model of the clamped lower support body.

[0091] The implementation principle of this application embodiment is as follows: the mobile workstation component 4 serves as the core carrier, and it circulates along a closed-loop path formed by the conveyor belt group 2 and three docking platforms connected in series. During operation, the unloaded mobile workstation component 4 enters the inlet slide 301 of the first docking platform from the end of the long conveyor belt 201. After the first photosensitive detector 602 detects that the workpiece is in place, it triggers the control sequence: the first feeding telescopic motor 305 drives the feeding pusher plate 308 to push the workpiece into the docking slide 302 and block the entrance; the first pushing cylinder 309 actuates, pushing a row of mobile station parts 4 in the docking slide 302 tightly against the side wall of the outlet slide 303, so that each workpiece slot 404 is precisely aligned with the station of the first unloading mechanism; after the flipping clamping part 8 of the first unloading mechanism receives the material from the vibratory plate and flips and straightens its posture, the spring-loaded robotic arm 9, while the mounting pressure block 16 presses down the corresponding snap-fit ​​plate 409 to open the workpiece slot 404, puts the first type of spring into the designated workpiece slot 404; then the first discharge telescopic motor 313 actuates, pushing the mobile station parts 4 that have completed loading to the short conveyor belt 202.

[0092] The mobile workstation component 4 is transported to the second docking platform via a short conveyor belt 202, where a similar inspection and positioning process is repeated, and a second type of spring is placed in by the second unloading mechanism. It then continues to flow into the third docking platform, where a third type of spring is placed in by the third unloading mechanism. Next, at a subsequent station on the same docking platform, the workpiece inspection mechanism 5 inspects the spring installation status of each workpiece slot 404. The rivet loading assembly 17 picks up rivets from the vibratory feeder via the docking table 1708, and after being lifted by the ejection mechanism, the rivet unloading robot arm 1702 grasps and inserts them into the positioning holes 407 of the mobile workstation component 4, which already contains springs.

[0093] The mobile workstation component 4, having completed all loading, continues its cycle. When it reaches the riveting assembly area, the spring piece assembly robot arm 28, assisted by the spring piece unloading cylinder 29, sequentially removes the spring pieces (pre-installed with rivets) from different workpiece slots 404 on the mobile workstation component 4. Simultaneously, the lower support assembly robot arm 31 removes the lower support body from the placement box on the second lifting platform mechanism. The two meet at the rotating station of the assembly table 33: the spring pieces are placed in the corresponding positions on the lower support body. Subsequently, the rotating platform 3303 rotates, sending the assembly to the riveting mechanism 34, where the upper riveting block 3403 and the lower riveting head 3406 cooperate to complete the riveting. Finally, the unloading robot arm 32 removes the finished product and guides it into different unloading slides 35 according to model, thus completing a fully automated assembly cycle for a lower support product. Throughout the process, the detection signals from each workstation coordinate and control the sequential actions of the cylinders, motors, and robot arms, ensuring smooth production rhythm and precise operation.
