Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, specifically a robotic arm for industrial loading and unloading. Background Technology

[0002] Robotic arms are industrial robots used to pick up, move, and place materials on industrial production lines, enabling material loading and unloading. They can replace manual labor in repetitive and high-intensity material handling tasks, improving efficiency and safety. They are widely used in machine tools, warehousing, injection molding, stamping, and other scenarios. In the process of loading and unloading sheet metal, existing robotic arms usually use negative pressure adsorption to fix the sheet metal workpiece. However, when double-sided processing or inspection of the sheet metal is required, and the sheet metal is placed directly flat on the worktable, it is difficult for the robotic arm to adsorb the sheet metal from below to achieve the flipping operation. Often, multiple robotic arms need to work together. Summary of the Invention

[0003] The purpose of this invention is to provide a robotic arm for industrial loading and unloading, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A robotic arm for industrial loading and unloading includes a robotic arm body, an adjustment module, and several suction modules. The adjustment module includes a drive mechanism and an adjustment box. The suction modules include connecting frames and several suction cups located on opposite sides of two connecting frames. The adjustment box has several connecting rod 1 and several connecting rod 2, located on opposite sides of the adjustment box. Two connecting rod 1 and two connecting rod 2 are staggered. The top of connecting rod 1 is rotatably connected to a positioning shaft 1 rotatably connected to an adjacent connecting frame, and the bottom of connecting rod 2 is rotatably connected to a positioning shaft 2 rotatably connected to an adjacent connecting frame. The two connecting frames are located at the top and bottom of the adjustment box, respectively.

[0006] The adjusting box is rotatably connected by a connecting shaft one and a connecting shaft two. The connecting shaft one is fixedly connected to a connecting rod one, and the connecting shaft two is fixedly connected to the top of a connecting rod two. The connecting rod two is rotatably connected to the adjusting box through the connecting shaft two.

[0007] Furthermore, the drive mechanism includes a fixed frame, a rotating disk, and a positioning seat;

[0008] The fixed frame is set on the output end of the robotic arm body, and the fixed frame is fixedly connected to the robotic arm body by a flange.

[0009] The rotating disk is rotatably connected inside the fixed frame;

[0010] The positioning seat is fixedly connected to the rotating disk, the adjusting box is fixedly connected to the positioning seat, and the top of another connecting rod is rotatably connected to the positioning seat.

[0011] Furthermore, the drive mechanism also includes a drive motor and a drive shaft;

[0012] The drive motor is fixedly connected inside the fixed frame;

[0013] The drive shaft is rotatably connected inside the fixed frame, the output end of the drive motor is connected to the drive shaft for transmission, and the drive shaft is fixedly connected to the rotating disk.

[0014] Preferably, the adjusting box is fixedly connected to a partition, and both connecting shaft one and connecting shaft two are rotatably connected to the partition. Inside the adjusting box, rotating shaft one and rotating shaft two are rotatably connected to the partition. Rotating shaft one is fixedly sleeved with missing gear one, missing gear two and missing gear three. Rotating shaft two is fixedly sleeved with a transmission gear. Connecting shaft one is fixedly sleeved with connecting gear one, and connecting shaft two is fixedly sleeved with connecting gear two. Connecting gear two meshes with the transmission gear for transmission. Connecting gear one meshes with missing gear one for transmission. Connecting gear two 261 corresponds only to missing gear two 226, and transmission gear 229 corresponds only to missing gear three 227.

[0015] Furthermore, an adjustment motor is fixedly connected inside the adjustment box, and a drive shaft is connected to the output end of the adjustment motor. Both the drive shaft and the rotating shaft are fixedly sleeved with bevel gears, and the two bevel gears mesh for transmission.

[0016] Preferably, both connecting rod one and connecting rod two are provided with circular grooves, and several fixed cylinders are fixedly connected inside the positioning seat and the adjusting box. A sliding block is slidably connected inside the fixed cylinder, and a circular block that abuts against the adjacent circular groove is fixedly connected to the sliding block. A return spring one that is fixedly connected to the inside of the fixed cylinder is fixedly connected to the sliding block.

[0017] Furthermore, the connecting frame is fixedly connected to several positioning rods, the positioning rods are rotatably connected to limit seats, the limit seats are slidably connected to sliding rods, the sliding rods are fixedly connected to fixed seats, the fixed seats are slidably connected to sliding seats, and the suction cup is fixedly connected to adjacent sliding seats.

[0018] Furthermore, a return spring 2, which is fixedly connected to the sliding seat, is fixedly connected inside the fixed seat.

[0020] Furthermore, several positioning rods are fixedly connected to baffles that are rotatably connected to the adjusting screw.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The system features two connecting rods, one from the adjusting box and the other from the connecting rod. The robotic arm moves the adsorption module onto the sheet metal, where it is adsorbed by the bottom adsorption module. The angle of the adjusting box can be adjusted via a drive mechanism, thereby adjusting the positions of the two adsorption modules. The adsorption and transfer of materials using these two modules improves loading and unloading efficiency. After processing one side of the sheet metal, when adsorbing the top surface using one adsorption module, connecting rods one and two can be rotated. Connecting rod one rotates downwards, while connecting rod two rotates upwards, aligning the suction cups of the two adsorption modules. At this point, connecting rods one and two can rotate towards each other, causing the bottom surface of the sheet metal to adhere to the other adsorption module. After separating one adsorption module from the sheet metal, connecting rods one and two can be rotated back to their original positions to flip the sheet metal. This allows for flipping operations on a single robotic arm, eliminating the need for multiple robotic arms and reducing costs.

[0023] 2. The positioning rod is connected to the limiting seat by rotation. The limiting seat can be rotated according to the shape of the plate, and the sliding rod can slide along the inside of the limiting seat to adjust the position of the suction cup. Then, the sliding rod can be pressed down by the pressure plate to position the suction cup. This is conducive to adjusting the position of the suction cup according to the shape of the plate and adapting to the adsorption of plates of different shapes. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] Please see Figure 1-4 In this embodiment of the invention, a robotic arm for industrial loading and unloading includes a robotic arm body 100, an adjustment module 200, and a plurality of suction modules 300. The adjustment module 200 includes a drive mechanism 210 and an adjustment box 220. The suction modules 300 include a connecting frame 310 and a plurality of suction cups 320. The suction cups 320 are located on opposite sides of two connecting frames 310. A fixing tube is provided on the side of the suction cups 320, and a flexible hose can be provided on the fixing tube. The flexible hose is arranged along the side of the connecting frame 310 outside the adjustment box 220 and connected to a negative pressure generator. At the same time, the negative pressure generator is connected to an air source, and the connection between the air source and the negative pressure generator is controlled by a valve.

[0037] The adjustment box 220 is provided with several connecting rods 1 230 and several connecting rods 240. The connecting rods 1 230 and 240 are located on both sides of the adjustment box 220. The two connecting rods 1 230 are staggered, and the two connecting rods 240 are also staggered. The top of the connecting rod 1 230 is rotatably connected to a positioning shaft 1 231 that is rotatably connected to the adjacent connecting frame 310. The bottom of the connecting rod 240 is rotatably connected to a positioning shaft 241 that is rotatably connected to the adjacent connecting frame 310. The two connecting frames 310 are located at the top and bottom of the adjustment box 220, respectively. The two connecting rods 1 230 are parallel to each other and have the same length, and the two connecting rods 240 are parallel to each other and have the same length. The adjustment box 220, the two connecting rods 1 230 and the top connecting frame 310 can form a parallelogram, and the adjustment box 220, the two connecting rods 240 and the bottom connecting frame 310 can also form a parallelogram.

[0038] The adjusting box 220 is rotatably connected to a first connecting shaft 250 and a second connecting shaft 260. The first connecting shaft 250 is fixedly connected to a first connecting rod 230, and the second connecting shaft 260 is fixedly connected to the top end of a second connecting rod 240. The bottom end of the first connecting rod 230 is rotatably connected to the adjusting box 220 through the first connecting shaft 250, while the bottom end of the other first connecting rod 230 is rotatably connected to the adjusting box 220 through a shaft. The second connecting rod 240 is rotatably connected to the adjusting box 220 through the second connecting shaft 260.

[0039] Specifically, the bottom adsorption module 300 can be moved onto the sheet material by moving the adjustment module 200 and adsorption module 300 of the robotic arm body 100. The air source is connected to the corresponding negative pressure generator by controlling the valve. The negative pressure generator generates negative pressure inside the suction cup 320, so that the sheet material can be adsorbed by the suction cup 320 of the adsorption module 300. Then, the sheet material can be transferred to the processing or inspection position by moving the adjustment module 200 and adsorption module 300 of the robotic arm body 100. After the sheet material is released by the suction cup 320, the sheet material is loaded. After processing or inspection, the sheet material can be adsorbed again by the suction cup 320 of the adsorption module 300 to unload the sheet material.

[0040] When processing or inspecting one side of the sheet metal is complete, and processing or inspection of the other side is required, connecting rod 230 can be rotated downwards and connecting rod 240 upwards. Since both connecting rods 230 and 240 are parallel and of equal length, the connecting frame 310 will maintain a constant angle during their rotation. After one adsorption module 300 rotates to the top of the adjusting box 220 and the other adsorption module 300 rotates to the bottom of the adjusting box 220, the suction cups 320 of the two adsorption modules 300 will be arranged opposite each other, positioned between the two connecting frames 310, thus allowing the other adsorption module to... The suction cup 320 of the attached module 300 corresponds to the bottom of the sheet metal. At this time, the connecting rod 1 230 and the connecting rod 240 can be rotated in opposite directions, so that the connecting rod 1 230 and the connecting rod 240 rotate towards each other, causing the two connecting frames 310 to gradually close. The suction cup 320 of the other adsorption module 300 is gradually attached to the bottom surface of the sheet metal. The sheet metal is held by the suction cup 320 of one adsorption module 300, and the sheet metal is released by the suction cup 320 of the other adsorption module 300. Then, the connecting rod 1 230 and the connecting rod 240 can be rotated back to their original positions. This allows the bottom surface of the sheet metal to face upwards, and the flipping operation can be performed on a single robot arm without the need for multiple robot arms to work together, which helps to reduce costs.

[0041] Example 1

[0042] like Figure 2 As shown, in this embodiment, the drive mechanism 210 includes a fixed frame 211, a rotating disk 212, a positioning seat 213, a drive motor 214, and a drive shaft 215;

[0043] A fixed frame 211 is set on the output end of the robotic arm body 100. The fixed frame 211 is fixedly connected to the robotic arm body 100 via a flange. A rotating disk 212 is rotatably connected inside the fixed frame 211. A positioning seat 213 is fixedly connected to the rotating disk 212. An adjustment box 220 is fixedly connected to the positioning seat 213. The adjustment box 220 can be connected to the fixed frame 211 via the rotating disk 212 and the positioning seat 213, thereby setting the adjustment box 220 on the output end of the robotic arm body 100. The top of another connecting rod 240 is rotatably connected to the positioning seat 213. The top of the other connecting rod 240 is rotatably connected to the positioning seat 213 via a shaft, so that the two connecting rods 240 are staggered. A drive motor 214 is fixedly connected inside the fixed frame 211. A drive shaft 215 is rotatably connected inside the fixed frame 211. The output end of the drive motor 214 is connected to the drive shaft 215. The drive shaft 215 is fixedly connected to the rotating disk 212.

[0044] In specific implementation, when the board material is moved to the processing or inspection position by the robotic arm body 100 during loading, the drive shaft 215 can be rotated by the drive motor 214. The drive shaft 215 can drive the rotating disk 212 to rotate within the fixed frame 211. The rotating disk 212 can drive the adjustment box 220 to rotate through the positioning seat 213. The adjustment box 220 can rotate through the connecting rod 1 230 and the connecting rod 240, thereby rotating the adjustment box 220 and the two adsorption modules 300 as a whole, adjusting the position of the two adsorption modules 300 so that one adsorption module 300 rotates to the top of the adjustment box 220 and the other adsorption module 300 rotates to the bottom of the adjustment box 220. At this time, the processed board material can be adsorbed by the other adsorption module 300.

[0045] After the processed sheet material is moved upward by the robotic arm body 100, the drive shaft 215 can be rotated in the opposite direction by the drive motor 214, so that one adsorption module 300 is rotated back to the bottom of the adjustment box 220. Then, the adjustment module 200 and the adsorption module 300 can be moved by the robotic arm body 100 to move the unprocessed sheet material on the adsorption module 300 to the processing position. After the unprocessed sheet material on the adsorption module 300 is released, the adjustment module 200 and the adsorption module 300 can be moved by the robotic arm body 100 to move the processed sheet material to the conveyor belt. Then, the adjustment module 200 and the adsorption module 300 can be moved by the robotic arm body 100 to adsorb the next sheet material. The loading and unloading can continue. The adsorption and transfer of materials by the two adsorption modules 300 can help improve the efficiency of loading and unloading.

[0046] like Figure 6 and Figure 7As shown, in this embodiment, the adjusting box 220 is fixedly connected to a partition 221. Connecting shaft 1 250 and connecting shaft 260 are both rotatably connected to the partition 221. Inside the adjusting box 220, rotating shaft 1 224 and rotating shaft 228 are rotatably connected to the partition 221. Rotating shaft 1 224 is fixedly sleeved with missing gear 1 225, missing gear 226, and missing gear 3 227. Rotating shaft 228 is fixedly sleeved with a transmission gear 229. Connecting shaft 1 250 is fixedly sleeved with connecting gear 1 251, and connecting shaft 260 is fixedly sleeved with connecting gear 261. Connecting gear 261 and the transmission gear... 229 meshing transmission, connecting gear 1 251 meshes with missing gear 1 225, connecting gear 2 261 corresponds only to missing gear 2 226, and transmission gear 229 corresponds only to missing gear 3 227. An adjustment motor 222 is fixedly connected inside the adjustment box 220. The output end of the adjustment motor 222 is connected to the transmission shaft 2221. The partition 221 can support and position the transmission shaft 2221, rotating shaft 1 224, rotating shaft 2 228, connecting shaft 1 250, and connecting shaft 2 260. Both the transmission shaft 2221 and rotating shaft 1 224 are fixedly sleeved with bevel gears 223, and the two bevel gears 223 mesh and transmit power.

[0047] In practice, when it is necessary to flip the sheet metal, the drive shaft 2221 can be rotated by adjusting the motor 222. The drive shaft 2221 can drive the rotating shaft 224 to rotate via the bevel gear 223. The rotating shaft 224 can drive the missing gears 225, 226, and 227 to rotate in the forward direction. The missing gear 225 can drive the connecting gear 251 to rotate, causing the connecting gear 251 to drive the connecting shaft 250 to rotate in the reverse direction. When the missing gears 226 and 227 rotate in the forward direction, the missing gear 226 can drive the connecting gear 261 to rotate. Since the missing gear 227 is disengaged from the drive gear 229 at this time, the connecting gear 261 can rotate smoothly. The movement causes the connecting gear 261 to drive the connecting shaft 260 to rotate in the opposite direction, thereby causing both the connecting shaft 250 and the connecting shaft 260 to rotate in the same direction. The connecting shaft 250 can drive a connecting rod 230 to rotate, while the connecting shaft 260 can drive a connecting rod 240 to rotate, thereby causing the connecting rod 230 to rotate downward and the connecting rod 240 to rotate upward, causing one adsorption module 300 to rotate to the top of the adjustment box 220 and the other adsorption module 300 to rotate to the bottom of the adjustment box 220. The suction cups 320 of the two adsorption modules 300 are arranged opposite to each other, so that the suction cup 320 of the other adsorption module 300 corresponds to the bottom of the board.

[0048] When rotating shaft 224 continues to drive the missing gears 225, 226, and 227 to rotate in the forward direction, the teeth on missing gear 225 will disengage from connecting gear 251, and the teeth on missing gear 226 will disengage from connecting gear 261. After rotating a certain angle, the teeth on missing gear 225 will re-mesh with connecting gear 251, while the missing teeth on missing gear 226 will remain on the corresponding connecting gear 261, and the teeth on missing gear 227 will mesh with transmission gear 229. At this time, rotating shaft 224 will continue to drive connecting shaft 250 to rotate in the reverse direction through missing gear 225 and connecting gear 251, while rotating shaft 224 will mesh with transmission gear 229 through missing gear 227. Gear 229 drives rotating shaft 228 to rotate, and rotating shaft 228 can drive connecting shaft 260 to rotate in the forward direction through transmission gear 229 and connecting gear 261. This causes connecting shaft 250 and connecting shaft 260 to rotate in opposite directions, so that the two connecting frames 310 can move closer to each other and transfer the board material from one adsorption module 300 to the other adsorption module 300. Then, by adjusting motor 222 to drive transmission shaft 2221 to rotate in the reverse direction, first connecting shaft 250 and connecting shaft 260 to rotate in opposite directions, and then to rotate in the same direction, connecting rod 230 and connecting rod 240 to rotate back to their original positions, and move the two adsorption modules 300 to their original positions. This makes it relatively simple to flip the board material.

[0049] like Figure 8-10 As shown, in this embodiment, the connecting frame 310 is fixedly connected with a plurality of positioning rods 311. The positioning rods 311 are rotatably connected to the limiting seat 340. The limiting seat 340 can be rotatably set inside the connecting frame 310 by the positioning rods 311. The limiting seat 340 is slidably connected to a sliding rod 341. The sliding rod 341 is fixedly connected to a fixed seat 350. The fixed seat 350 is slidably connected to a sliding seat 351. The suction cup 320 is fixedly connected to the adjacent sliding seat 351. The fixed seat 350 is fixedly connected to a second return spring 352 that is fixedly connected to the sliding seat 351. The second return spring 352 can support the sliding seat 351, thereby supporting the suction cup 320.

[0050] In practice, the limiting seat 340 can be rotated according to the shape of the plate, and the sliding rod 341 can slide along the inside of the limiting seat 340. This can adjust the position of the fixed seat 350. The fixed seat 350 can drive the suction cup 320 to move through the second return spring 352, and then adjust the position of the suction cup 320 as needed. This is beneficial to adjust the position of the suction cup 320 according to the shape of the plate, so as to adapt to the adsorption of plates of different shapes. When the two connecting frames 310 are closed, the suction cup 320 is pressed against the plate, and the sliding seat 351 can slide inside the fixed seat 350, so that the suction cup 320 can successfully adsorb the plate.

[0051] Example 2

[0052] Based on Example 1, such as Figure 5 As shown, in this embodiment, both connecting rod 1 230 and connecting rod 240 are provided with circular grooves 280. The positioning seat 213 and the adjusting box 220 are both fixedly connected with a number of fixed cylinders 270. A sliding block 271 is slidably connected inside the fixed cylinder 270. A circular block 272 that abuts against the adjacent circular groove 280 is fixedly connected to the sliding block 271. A return spring 273 that is fixedly connected to the inside of the fixed cylinder 270 is fixedly connected to the sliding block 271. Each connecting rod 1 230 and connecting rod 240 is provided with two fixed cylinders 270.

[0053] In specific implementation, when connecting rod 1 230 and connecting rod 240 rotate to the side of fixed cylinder 270, the edges of connecting rod 1 230 and connecting rod 240 can press against circular block 272, causing circular block 272 and sliding block 271 to move into fixed cylinder 270. When connecting rod 1 230 and connecting rod 240 rotate to a vertical position, circular groove 280 will correspond to adjacent circular block 272. Under the action of return spring 1 273, circular block 272 can be pressed against the inside of circular groove 280, thereby limiting connecting rod 1 230 and connecting rod 240 and maintaining the angle of connecting rod 1 230 and connecting rod 240. In this way, in case of a shortage... When the teeth on gear 1 225 disengage from connecting gear 1 251, the teeth on missing gear 2 226 disengage from connecting gear 2 261, and the teeth on missing gear 3 227 disengage from transmission gear 229, the angle between connecting rod 1 230 and connecting rod 2 240 can be maintained by the circular block 272, thereby maintaining the position of connecting frame 310. When connecting rod 1 230 and connecting rod 2 240 rotate, the circular groove 280 can squeeze the circular block 272, causing the circular block 272 and sliding block 271 to move into the fixed cylinder 270, so that the circular grooves 280 on connecting rod 1 230 and connecting rod 2 240 can be smoothly separated from the corresponding circular blocks 272.

[0054] like Figure 8 and Figure 9 As shown, in this embodiment, a pressure plate 330 is slidably connected inside the connecting frame 310, and an adjusting screw 313 is rotatably connected to the connecting frame 310 and screwed into the pressure plate 330. The pressure plate 330 can be positioned by adjusting the screw 313. Both the pressure plate 330 and the end of the sliding rod 341 are provided with rough surfaces. Several positioning rods 311 are fixedly connected to baffles 312 that are rotatably connected to the adjusting screw 313. The positioning rods 311 can position the baffles 312, and the baffles 312 can position the end of the adjusting screw 313. The positioning rods 311 pass through the inside of the pressure plate 330.

[0055] In practice, rotating the adjusting screw 313 allows the pressure plate 330 to slide along the inside of the connecting frame 310, thereby adjusting the position of the pressure plate 330 so that it presses against the sliding rod 341, making the rough surfaces of the pressure plate 330 and the sliding rod 341 tightly adhere to each other, thus positioning the sliding rod 341 and the suction cup 320. The rough surface helps to improve the positioning effect of the pressure plate 330 on the sliding rod 341. The adjusting screw 313 can be rotated in the opposite direction to allow the pressure plate 330 to slide in the opposite direction along the inside of the connecting frame 310, separating the pressure plate 330 from the sliding rod 341. At this time, the positions of the sliding rod 341 and the suction cup 320 can be adjusted as needed.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
