Description

Technical Field

[0001] This application relates to the field of robotic arm technology, and more specifically, to a robotic arm for a smart fastener production line. Background Technology

[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They are used in a broad range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics. Various types of fasteners can be found on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies. They are among the most widely used basic mechanical components. During the production process, fasteners need to be sorted and inspected to identify defective products and prevent them from entering the market. Therefore, robotic arms are typically used to move fasteners between two points, transporting them to a sorting area for further sorting.

[0003] A search revealed that Chinese patent CN206645515U discloses an intelligent robotic handling device, comprising a frame, a horizontal linear sliding mechanism, a linear lifting mechanism, and a robotic arm mechanism. The frame includes a support column and a crossbeam; the support column is vertically positioned, and the crossbeam is horizontally mounted on the support column. The horizontal linear sliding mechanism is horizontally and linearly slidable on the crossbeam. The linear lifting mechanism is linearly and vertically mounted on the horizontal linear sliding mechanism. The robotic arm mechanism is mounted on the lower end of the linear lifting mechanism. Therefore, this intelligent robotic handling device can automatically transport objects from one location to a destination, thereby reducing labor intensity and improving production efficiency. Furthermore, this intelligent robotic handling device also possesses advantages such as simple structure, novel design, high degree of automation, low cost, small size, minimal space occupation, flexible layout, precise gripping and conveying, fast response speed, stable operation, simple operation, convenient installation and maintenance, and ease of promotion.

[0004] Regarding the aforementioned technologies, the applicant believes that while the current robotic arms can transport fasteners to designated locations for sorting and operate back and forth between these two points, their overall workflow, which involves the separate coordination of multiple cylinders and motors to achieve movement, lifting, and gripping actions, significantly increases the overall cost of the robotic arms and requires a large footprint, thus hindering their widespread adoption. Therefore, we propose a robotic arm for intelligent fastener production lines. Summary of the Invention

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] Please see Figure 1-8 A robotic arm for a smart fastener production line includes a main body module 100 and a robotic gripper module 200. The main body module 100 includes a support frame 110, a conveying device 120 on one side of the support frame 110, a sorting table 130 on the other side of the support frame 110, and a translation component 140 at the bottom of the support frame 110. The robotic gripper module 200 includes two swing arm assemblies 210, each mounted on the support frame 110. A linkage belt 220 drives the outer surfaces of the two swing arm assemblies 210 together. A hollow plate 230 is movably connected between one end of the two swing arm assemblies 210. The hollow plate 230 contains a... The lifting assembly 240 and the hollow plate 230 are both equipped with clamping assemblies 250. Both clamping assemblies 250 are close to the bottom of the hollow plate 230 and are connected to the lifting assembly 240. The rear end face of the support frame 110 is equipped with a magnetic self-locking assembly 260, which is movably connected to the hollow plate 230 and is compatible with the lifting assembly 240. An L-shaped stop bar 270 is fixedly connected to the side of the support frame 110 near the conveying device 120. The lower part of the support frame 110 is equipped with a drive assembly 280, which is connected to one of the swing arm assemblies 210.

[0032] During operation, the operator activates the drive assembly 280, which drives one of the swing arm assemblies 210. Through the linkage belt 220, both swing arm assemblies 210 swing simultaneously, causing the hollow plate 230 to swing. This causes the magnetic self-locking assembly 260 to engage with the inner wall of the lifting assembly 240. Then, as the hollow plate 230 gradually swings above the conveyor 120, the lifting assembly 240 contacts the L-shaped stop bar 270. As the hollow plate 230 descends, the lifting assembly 240 pulls the clamping assembly 250, bringing the two clamping assemblies 250 closer together. The clamping action is completed when the two clamping assemblies 250 descend to the fastener position above the conveyor 120. The magnetic self-locking component 260 will lock the state of the lifting component 240, thereby locking the gripping action of the two clamping components 250. After the gripping is completed, the two swing arm components 210 will swing to drive the hollow plate 230 to reset. When the hollow plate 230 is above the sorting table 130, the magnetic self-locking component 260 will withdraw the lifting component 240, causing the lifting component 240 to reset and drive the two clamping components 250 to open, so that the fasteners are placed above the sorting table 130 for sorting. The hollow plate 230 will repeat this step, thereby completing the repeated operation between the two workstations. This robot is driven by only a single drive component 280, which has a low overall cost and a small footprint, making it easy to use.

[0033] The lifting assembly 240 includes a sliding rod 241 movably connected inside the hollow plate 230. A first spring 242 is fixedly connected between the top of the sliding rod 241 and the top of the inner wall of the hollow plate 230. Both sides of the hollow plate 230 have slotted sections. A lifting rod 243 adapted to an L-shaped stop bar 270 is fixedly connected to one side of the sliding rod 241. The lifting rod 243 extends to the outside of the hollow plate 230 through one of the slotted sections. Two linkage rods 244 are hinged to the lower part of the outer surface of the sliding rod 241. The clamping assembly 250 includes a movable rod fixedly connected to the lower part of one side of the hollow plate 230. A fitting block 251 is slidably fitted onto the outer surface of the movable rod. The top of the fitting block 251 is hinged to one end of one of the linkage rods 244. A moving block 252 is fixedly connected to the bottom of the fitting block 251. A threaded rod 253 is threadedly connected to the inside of the moving block 252. One end of the sliding rod 241 is rotatably connected to a clamping plate 254. The top of the clamping plate 254 is slidably connected to the bottom of the movable rod. Multiple anti-slip grooves 255 are provided on one side of the clamping plate 254. The magnetic self-locking assembly 260 includes a ratchet groove 261 provided on the rear end face of the sliding rod 241. A ratchet rack 262 is movably connected to the rear end face of the hollow plate 230. One end of the ratchet rack 262 is adapted to the inner wall of the ratchet groove 261. The other end of the ratchet rack 262 is fixedly connected to a first magnetic block 263. A second spring 264 is fixedly connected between the first magnetic block 263 and the rear end face of the hollow plate 230. The second spring 264 is located outside the ratchet rack 262. The magnetic self-locking assembly 260 also includes a mounting plate fixedly connected to the rear end face of the support frame 110. A second magnetic block 265 is fixedly connected to the front end face of the mounting plate away from the support frame 110. The second magnetic block 265 is magnetically connected to the first magnetic block 263.

[0034] The hollow plate 230 is swung by the telescopic arm 213, causing the first magnetic block 263 to disengage from the second magnetic block 265. The second spring 264 contracts, causing the ratchet 262 to slide into the ratchet groove 261. As the hollow plate 230 gradually swings above the conveyor 120, the lifting assembly 240 will contact the L-shaped stop bar 270. As the hollow plate 230 gradually descends, the lifting rod 243 will pull the sliding rod 241. At the same time, the first spring 242 contracts, preventing the sliding rod 241 from changing position. The sliding rod 241 pulls the two clamping assemblies 250 through the two linkage rods 244, causing the sleeve block 251 to slide and move the clamping plate 254, bringing the two clamping plates 254 closer together. The clamping action is completed when the two clamping plates 254 descend to the fastener position above the conveyor 120. 262 will slide inside the ratchet groove 261. When the gripping action is completed, the ratchet 262 and the ratchet groove 261 lock the position of the sliding rod 241, thereby locking the gripping action of the two clamping plates 254. After the gripping is completed, the two swing arm assemblies 210 will swing to drive the hollow plate 230 to reset. When the hollow plate 230 is above the sorting table 130, the first magnetic block 263 will be attracted by the second magnetic block 265, thereby releasing the lock on the sliding rod 241, so that the first spring 242 pushes the sliding rod 241 to reset, thereby driving the two clamping plates 254 to open, and then the fastener is placed above the sorting table 130 for sorting. The hollow plate 230 repeats this step, thereby completing the repeated operation between the two workstations. This robot is driven by only a single motor, with low overall cost and small footprint.

[0035] The drive assembly 280 includes a semi-circular gear 281 rotatably connected to the rear end face of the support frame 110. A connecting gear 282 is fixedly connected to one of the swing arm assemblies 210, and the connecting gear 282 meshes with the semi-circular gear 281. A swing rod 283 is fixedly connected to the lower part of the outer surface of the semi-circular gear 281. A drive groove is formed on the inner wall of the swing rod 283. The drive assembly 280 also includes a motor fixedly connected to the front end face of the support frame 110. The output shaft of the motor extends to the rear end face of the support frame 110 and is fixedly connected to a turntable 284. A drive shaft 285 is fixedly connected to the rear end face of the turntable 284, and the drive shaft 285 is slidably connected inside the drive groove. When the motor is turned on, it will drive the turntable 284 to rotate the drive shaft 285. The drive shaft 285 will swing inside the drive groove and drive the half-circle gear 281 to swing back and forth through the swing rod 283. The half-circle gear 281 will drive the connecting gear 282 to roll back and forth. The connecting gear 282 drives the rotating shaft to rotate through the transmission roller 211. At the same time, the linkage belt 220 causes the two swing arm assemblies 210 to swing simultaneously.

[0036] The swing arm assembly 210 includes a rotating shaft rotatably connected inside the support frame 110. A transmission roller 211 is fixedly connected to the rear end of the rotating shaft. The rear end face of the transmission roller 211 is fixedly connected to a connecting gear 282. The outer surface of the transmission roller 211 is connected to a driving belt 220. A swing arm 212 is fixedly connected to the front end of the rotating shaft. A telescopic arm 213 is movably connected inside the swing arm 212. One end of the telescopic arm 213 extends to the outside of the swing arm 212 and is rotatably connected to the hollow plate 230. The swing arm assembly 210 also includes multiple locking holes equidistantly spaced in a straight line inside the telescopic arm 213. A threaded pin 214 is movably inserted into one of the locking holes. Both ends of the threaded pin 214 are threaded with fixing nuts 215. The translation component 140 includes two slide rails 141. A sliding table 142 is slidably connected between the outer surfaces of the two slide rails 141. The bottom of the support frame 110 is fixedly connected to the top of the sliding table 142. The tops of the two slide rails 141 are provided with multiple fixing holes 143 at equal intervals in a straight line. The top of the sliding table 142 is threaded with two fixing bolts 144. The bottom ends of the two fixing bolts 144 extend into the interior of two of the fixing holes 143.

[0037] The telescopic arm 213 can slide inside the swing arm 212 to extend and retract, thereby adjusting the lever arm length. Then, the lever arm length can be locked by inserting the threaded pin 214 into the locking hole and installing the fixing nut 215. The sliding table 142 can slide on the slide rail 141 to adjust the position of the support frame 110. Then, the position of the sliding table 142 can be locked by turning the fixing bolt 144 into the corresponding fixing hole 143, so that the clamping distance can be adjusted as needed, making it convenient to clamp fasteners at different distances.

[0038] The implementation principle of this application embodiment is as follows: During use, when the operator turns on the motor, the motor will drive the turntable 284 to rotate the drive shaft 285. The drive shaft 285 will swing inside the drive groove and drive the half-circle gear 281 to swing back and forth through the swing rod 283. The half-circle gear 281 will drive the connecting gear 282 to roll back and forth. The connecting gear 282 drives the rotating shaft to rotate through the transmission roller 211. At the same time, the linkage of the linkage belt 220 causes the two swing arm assemblies 210 to swing simultaneously. The rotating shaft drives the telescopic arm 213 to swing through the swing arm 212. The telescopic arm 213 drives the hollow plate 230 to swing, causing the first magnetic block 263 to disengage from the second magnetic block 265. The second spring 264 retracts and drives the ratchet rack 262 to slide into place. The rack 240 enters the ratchet groove 261. As the hollow plate 230 gradually swings above the conveyor 120, the lifting component 240 will contact the L-shaped stop bar 270. As the hollow plate 230 gradually descends, the lifting rod 243 will pull the sliding rod 241, while the first spring 242 contracts, preventing the sliding rod 241 from changing position. This causes the sliding rod 241 to pull the two clamping components 250 via the two linkage rods 244, causing the sleeve block 251 to slide and move the clamping plate 254, bringing the two clamping plates 254 closer together. The clamping action is completed when the two clamping plates 254 descend to the fastener position above the conveyor 120. The ratchet 262 will slide inside the ratchet groove 261. When the clamping action is completed, the ratchet 262... The 62 mechanism, in conjunction with the ratchet 261, locks the position of the sliding rod 241, thus locking the gripping action of the two clamping plates 254. After gripping, the two swing arm assemblies 210 will swing, causing the hollow plate 230 to reset. When the hollow plate 230 is above the sorting table 130, the first magnetic block 263 will be attracted by the second magnetic block 265, thereby releasing the lock on the sliding rod 241. This allows the first spring 242 to push the sliding rod 241 back to its original position, causing the two clamping plates 254 to open, allowing the fasteners to be placed above the sorting table 130 for sorting. The hollow plate 230 then repeats this process, thus completing repeated operations between the two workstations. This robotic arm is driven by only a single motor, resulting in low overall cost and minimal footprint. With a small footprint, it is easy to use. The telescopic arm 213 can slide and extend inside the swing arm 212 to adjust the lever arm length. Then, the lever arm length can be locked by inserting the threaded pin 214 into the locking hole and installing the fixing nut 215. The sliding table 142 can slide on the slide rail 141 to adjust the position of the support frame 110. Then, the position of the sliding table 142 is locked by turning the fixing bolt 144 into the corresponding fixing hole 143, so that the clamping distance can be adjusted as needed to clamp fasteners at different distances. At the same time, rotating the threaded rod 253 can drive the clamping plate 254 to move, so that the initial position of the clamping plate 254 can be adjusted according to the size of the fastener.This allows the robotic arm to grip fasteners of varying widths.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
