Description

Technical Field

[0001] This utility model relates to the field of industrial manufacturing, specifically to an intelligent robot for industrial manufacturing. Background Technology

[0002] In the rapid development of modern manufacturing, the demands for automation and intelligence in industrial production continue to rise. Industrial robots, as a key carrier of advanced manufacturing technology, have become an important means of improving production efficiency, ensuring product quality, and freeing up manpower.

[0003] While traditional industrial robots can perform basic tasks such as handling, welding, and assembly, their limitations are becoming increasingly apparent as production scenarios become more complex. For example, when faced with workpieces of irregular shape and unpredictable position, traditional robots lack sufficient grasping precision and flexibility, making it difficult to meet the demands of high-precision operations. Furthermore, in multi-variety, small-batch production models, the programming and debugging process for traditional robots is cumbersome, making it difficult to quickly adapt to frequent product changes, resulting in low production efficiency.

[0004] Pressure sensors, as key components for robots to sense external forces, suffer from poor sensing accuracy and slow response speed in traditional industrial robots. This makes it difficult to accurately monitor subtle changes in gripping force in real time, easily leading to workpiece slippage or damage during the gripping process. The application of lidar sensors in industrial robots is not yet widespread, and some existing systems suffer from limited scanning range and low resolution, failing to provide robots with comprehensive and accurate information about the operating environment and severely restricting their adaptability to complex scenarios.

[0005] To overcome these challenges, the industry is constantly exploring and innovating, and is committed to developing more intelligent, high-precision, and highly adaptable industrial manufacturing intelligent robots. It is hoped that by introducing advanced sensor technology, optimizing mechanical structure design, and innovating control algorithms, the operational capabilities and efficiency of industrial robots in complex environments can be greatly improved. This is also the important background for the research and development of this industrial manufacturing intelligent robot. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0039] like Figures 1 to 6 As shown, this utility model discloses an intelligent robot for industrial manufacturing, including a first adjustment mechanism 2, a second adjustment mechanism 3, a connector 1, a gripping component 5, and a laser radar sensor 4.

[0040] The first adjustment mechanism 2 is connected to the connector 1 via the second adjustment mechanism 3. The first adjustment mechanism 2 includes a housing 201, a first motor 202, and a top plate 203. The housing 201 can be a hollow cuboid structure with an opening at the top. The top plate 203 is rotatably connected to the opening at the top of the housing 201 via bearings. The inner ring of the bearing is interference-fitted with the top plate 203, and the outer ring is interference-fitted with the inner wall of the housing 201. This ensures both flexible rotation of the top plate 203 relative to the housing 201 and stable connection between the two. The first motor 202 is bolted to the bottom surface of the housing 201. The first motor 202 can be a servo motor, and its output end is connected to the center of the bottom of the top plate 203 via a coupling. When the first motor 202 operates, it drives the top plate 203 to rotate 360 ​​degrees around its own axis in a horizontal plane, thereby driving the second adjustment mechanism 3 connected to the top plate 203 to achieve horizontal rotation adjustment.

[0041] The second adjustment mechanism 3 is connected to the top plate 203 and includes a base 302, a second motor 301, a first support arm 303, a third motor 304, a second support arm 305, a third support arm 306, and a fourth motor 307. The base 302 is fixedly connected to the upper surface of the top plate 203 by bolts. One side of the base 302 is rotatably connected to one end of the first support arm 303 via a pin, allowing the first support arm 303 to rotate around the pin in a vertical plane. The second motor 301 is fixedly connected to the base 302 by bolts, and its output end is connected to the first support arm 303. When the second motor 301 is working, it can drive the first support arm 303 to rotate around the pin.

[0042] The other end of the first arm 303 is rotatably connected to one end of the second arm 305 via a pin. The third motor 304 is bolted to the first arm 303, and its output end is also connected to the second arm 305 to drive the second arm 305 to rotate in a vertical plane around the pin connected to the first arm 303. The other end of the second arm 305 is rotatably connected to one end of the third arm 306 via a pin. The fourth motor 307 is bolted to the second arm 305, and its output end is connected to the third arm 306 to drive the third arm 306 to rotate in a vertical plane around the pin connected to the second arm 305. The other end of the third arm 306 is rotatably connected to the connector 1 via a pin, and a corresponding motor can be installed at this connection point to drive the connector 1 to rotate around the pin, thereby achieving multi-position adjustment of the connector 1.

[0043] The first adjustment mechanism 2 and the second adjustment mechanism 3 cooperate with each other. The first adjustment mechanism 2 drives the second adjustment mechanism 3 to rotate horizontally as a whole. The second adjustment mechanism 3 realizes the adjustment of the connector 1 at different heights and horizontal positions through the rotation of each arm. It works together to drive the connector 1 to achieve precise translation and rotation adjustment in three-dimensional space, thereby ensuring that the gripping component 5 can flexibly reach any position within the working range.

[0044] The end of the connector 1 is rigidly connected to the gripping component 5. This rigid connection can be achieved by bolting. By machining threaded holes at corresponding positions on the end of the connector 1 and the gripping component 5, the two are fastened with bolts to ensure that the gripping component 5 will not loosen or shift relative to the connector 1 during operation, thus ensuring the stability and accuracy of the gripping action.

[0045] The gripping assembly 5 includes a drive unit, three grippers 503, and nine pressure sensors 504. The three grippers 503 are arranged in a ring with equal spacing. This distribution allows the grippers to apply force more evenly when gripping the workpiece, thus improving gripping stability.

[0046] Each gripper 503 has three pressure sensors 504 on its clamping surface, which are equidistantly distributed along the length of the gripper 503. The sensing surface of the pressure sensor 504 protrudes 0.5-1mm from the clamping surface of the gripper 503. This design ensures that the pressure sensor 504 can preferentially contact the workpiece, accurately sensing pressure changes during clamping and avoiding inaccurate pressure monitoring due to the gripper body contacting the workpiece first. The pressure sensor 504 can be a strain gauge type pressure sensor, which has high measurement accuracy and stability and can monitor the pressure value when the gripper contacts the workpiece in real time.

[0047] The driving components include a base plate 501, a driving ring 505, a connecting plate 507, a crossbeam 508, an electric push rod 509, and a groove 510 corresponding to the number of grippers 503, a first connecting block 506, and a second connecting block 502.

[0048] The electric actuator 509 is fixedly connected to the connector 1 by bolts. The output end of the electric actuator 509 is connected to the crossbeam 508 via a coupling to ensure stable power transmission. The crossbeam 508 is fixedly connected to the connecting plate 507 by welding. The connecting plate 507 is also welded to the drive ring 505, making these components a whole that move synchronously under the drive of the electric actuator 509.

[0049] The groove 510 is machined on the drive ring 505. The shape of the groove 510 is adapted to the first connecting block 506. The first connecting block 506 extends into the groove 510 and is rotatably connected to the drive ring 505 via a pin, allowing the first connecting block 506 to rotate flexibly around the pin within the groove 510. The end of the first connecting block 506 away from the drive ring 505 is rotatably connected to the gripper 503 via a pin. The middle part of the gripper 503 is also rotatably connected to the second connecting block 502 via a pin. The second connecting block 502 is fixedly connected to the base plate 501 by bolts. The base plate 501 is connected to the connector 1 by bolts.

[0050] When the output end of the electric push rod 509 extends, driving the drive ring 505 to move closer to the base plate 501, the drive ring 505 drives the first connecting block 506 to move through the groove 510. Since the second connecting block 502 is fixed on the base plate 501 and the grippers 503 are rotatably connected to the second connecting block 502, under the pushing action of the first connecting block 506, the three grippers 503 will rotate around the connection point with the second connecting block 502 as the fulcrum, thereby achieving a mutual closing action to clamp the workpiece. When the output end of the electric push rod 509 retracts, driving the drive ring 505 to move away from the base plate 501, under the pulling action of the first connecting block 506, the three grippers 503 will separate from each other, releasing the clamped workpiece.

[0051] The lidar sensor 4 is fixed to the side of the connector 1 near the gripping assembly 5 via a bracket, with its detection direction facing the working area of ​​the gripping assembly 5. The lidar sensor 4 can perform a three-dimensional scan of the workpiece within the working area of ​​the gripping assembly 5, acquiring information such as the workpiece's spatial position, shape, size, and orientation. This provides a basis for the first adjustment mechanism 2 and the second adjustment mechanism 3 to adjust the position and orientation of the connector 1, enabling the gripping assembly 5 to accurately approach and grip the workpiece. Simultaneously, during the gripping process, the lidar sensor 4 can also monitor the workpiece's status in real time, working in conjunction with the pressure sensor 504 to ensure the safety and stability of the gripping action.

[0052] The detailed workflow of the lidar sensor 4 and pressure sensor 504 is as follows: Before the gripping operation begins, the lidar sensor 4 is activated and scans the work area, transmitting the acquired 3D data of the workpiece to the robot's control system. The control system plans the motion path of the gripping component 5 based on this data, controlling the first adjustment mechanism 2 and the second adjustment mechanism 3 to drive the connecting head 1 and the gripping component 5 to a suitable gripping position. When the gripping component 5 approaches the workpiece, the lidar sensor 4 continuously monitors the workpiece position, assisting the control system in fine-tuning the posture of the gripping component 5. When the gripper 503 begins to close and contact the workpiece, the pressure sensor 504 is activated. The system triggers and transmits the detected pressure data to the control system in real time. The control system determines whether the clamping force is appropriate based on the pressure data. If the pressure is too low, the electric push rod 509 is extended further to increase the clamping force. If the pressure is too high, the electric push rod 509 is retracted appropriately to reduce the clamping force. At the same time, the system combines the workpiece status monitored by the lidar sensor 4 to ensure that the workpiece is clamped stably and safely. During the movement after gripping, the pressure sensor 504 continuously monitors the pressure changes. If abnormal pressure fluctuations occur, the control system combines the monitoring data from the lidar sensor 4 to determine whether the workpiece has slipped or shifted its position, and makes timely adjustments.

[0053] This invention enables flexible adjustment of the connector in three-dimensional space through a first adjustment mechanism and a second adjustment mechanism. The gripping component can stably and reliably grip the workpiece, the pressure sensor can monitor the clamping pressure in real time, and the lidar sensor can provide accurate environmental information for the gripping operation. The coordinated work of all components improves the operation accuracy and reliability of the intelligent robot in industrial manufacturing and is suitable for various industrial manufacturing scenarios.

[0054] It should be noted that the data acquisition and transmission of the lidar sensor 4, the pressure detection and signal transmission of the pressure sensor 504, and the conventional logical judgment and motion control performed by the robot control system based on the sensor data all adopt existing known sensor working principles and robot control technology. The improvement of this utility model lies in combining the lidar sensor 4 and the pressure sensor 504 with a specific mechanical structure to form a collaborative whole, rather than improving these known working processes themselves.

[0055] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
