Description

Technical Field

[0001] This utility model relates to the technical field of scooter production or packaging lines, and in particular to a pneumatic handling robotic arm device for picking up and putting scooters into boxes. Background Technology

[0002] In the production, assembly, and packaging of scooters, the entire scooter needs to be picked up and placed smoothly into a box. Scooters are characterized by their irregular structure, unique center of gravity distribution, and easily damaged surfaces (such as pedals and handlebars), making robotic arms crucial. Currently, most robotic arms use motor drives combined with linkage mechanisms, or hydraulic systems as the power source. Motor-driven systems typically require intermediate transmission components such as reducers and gears to convert rotary motion into the required linear or articulated motion. These transmission chains often result in a multi-layered robotic arm structure, increasing overall weight and manufacturing costs. Furthermore, under frequent start-stop conditions, the inertia of moving parts can cause vibrations in the end effector. While hydraulic drives offer high output force, they suffer from higher energy consumption, stringent system sealing requirements, and highly specialized maintenance. For general material handling applications, their economy and ease of use sometimes fall short of ideal performance.

[0003] In operations requiring rapid vertical picking and placing or demanding protection of the scooter surface, the rigid transmission structure and fixed installation of the end effector in traditional robotic arms sometimes struggle to adapt quickly to minor unevenness or angular deviations on the scooter surface, potentially affecting the stability and reliability of the gripping action. Therefore, exploring a robotic arm structure that is more direct in its design, more flexible in its transmission, and particularly capable of enhancing the end effector's adaptability to the scooter surface and adapting to the internal space of the packaging box to achieve precise placement is of significant practical value. Utility Model Content

[0004] In view of this, the present invention provides a pneumatic handling robotic arm for picking up and putting scooters into a box. The robotic arm has its own structural layout features, which are designed to safely, efficiently and flexibly complete the picking up and putting of scooters into the box.

[0005] The objective of this utility model is achieved through the following technical solution: A pneumatic handling robot arm for picking up and placing scooters into a box includes a base, a column fixedly mounted on the base, a column rotation joint disposed on the top of the column, a primary swing arm with one end connected to the column rotation joint, an intermediate rotation joint disposed at the end of the primary swing arm away from the column rotation joint, a secondary swing arm with one end connected to the intermediate rotation joint, a cylinder with its cylinder body hinged to the secondary swing arm, a transmission mechanism, and a sponge suction cup clamp directly or indirectly mounted on the free end of the steel wire rope. The sponge suction cup clamp is used to adsorb scooters. The transmission mechanism includes a steel wire rope and a guide mechanism. The guide mechanism is disposed on the secondary swing arm. One end of the steel wire rope is connected to the piston rod of the cylinder, and the other end passes around the guide mechanism and is connected to the sponge suction cup clamp.

[0006] This solution describes a pneumatic handling robot arm with a unique structural layout for picking up and placing scooters into a container. Its core feature is the direct hinge of a cylinder to a secondary swing arm, using a wire rope transmission mechanism to directly transmit the linear motion of the cylinder piston rod to a sponge suction cup gripper mounted on the free end of the wire rope. This design brings the drive unit closer to the end effector, allowing the cylinder's movement to be directly and quickly converted into the vertical lifting and lowering motion of the sponge suction cup gripper relative to the secondary swing arm. This direct drive method reduces intermediate transmission links, contributing to improved end-effector response speed. Because the sponge suction cup gripper is suspended by a wire rope, it possesses a certain degree of floating adaptability. When the gripper contacts the scooter surface, the flexibility of the wire rope allows for slight adjustments to its posture, making it easier to achieve a good fit with uneven scooter surfaces, improving the success rate and stability of the suction. The entire system still uses pneumatics as the primary power source, maintaining the characteristics of a simple pneumatic system structure and convenient maintenance. The secondary swing arm is connected to the primary swing arm via an intermediate rotary joint, and the primary swing arm is connected to the column via a column rotary joint. This multi-joint structure preserves a large range of motion for the robotic arm in the horizontal plane. The layout of the cylinder fixed to the secondary swing arm allows the power source for lifting operations to move with the work point, resulting in a relatively short force flow path. In summary, this structural design provides a handling approach that emphasizes rapid vertical lifting at the end of the lifting process and adaptive centering.

[0007] Preferably, the adsorption surface of the sponge suction cup clamp is a rectangular plane.

[0008] The suction cup clamp's adsorption surface is designed as a rectangular plane, making it particularly suitable for handling scooters with large, flat surfaces, such as common boards and boxes. The rectangular adsorption surface provides a wider, continuous adsorption area than a circular adsorption surface of the same size, helping to increase the effective contact area with the scooter, thereby improving the adhesion and reducing the risk of the scooter slipping during transport. The rectangular edge shape also makes it easier for the operator to visually align the scooter's corners for more precise positioning. This shape is also well-suited for regularly shaped scooters.

[0009] Preferably, it also includes a pneumatic control box, which is mounted on the first-stage rocker arm and connected to the cylinder via an air pipe.

[0010] Placing the pneumatic control box on the primary swing arm is a solution for locating control components close to the system. This arrangement shortens the air pipe connection length between the control box and the cylinder mounted on the secondary swing arm, reducing pressure loss along the pipe and helping to ensure more efficient air pressure transmission to the cylinder. The shorter pipe layout also simplifies the piping routing, potentially reducing the risk of interference with other moving parts due to excessive pipe length. Centralized installation of the control box facilitates the integration of pneumatic components such as pressure regulators and reversing devices, making system maintenance and inspection more focused.

[0011] Preferably, the air circuit of the air control box is equipped with a pressure regulating water filter.

[0012] Integrating a pressure-regulating filter into the air circuit of the pneumatic control box plays a crucial role in maintaining the stable and reliable operation of the pneumatic system. The pressure-regulating filter removes moisture, oil mist, and small solid particles from the compressed air, providing the cylinder with cleaner, drier working gas. This helps reduce wear and corrosion caused by impurities on the cylinder's inner wall and seals, thereby extending the cylinder's service life. Its pressure-regulating function stabilizes the working pressure supplied to the cylinder, preventing fluctuations in air source pressure that could lead to unstable output force or uneven movement speed of the robotic arm, ensuring consistent handling actions.

[0013] Preferably, it also includes a control handle, which is connected to the sponge suction cup clamp.

[0014] The control handle, directly connected to the foam suction cup clamp, provides the operator with a direct way to control the end effector. The operator can fine-tune the position and orientation of the foam suction cup clamp using the handle, which is particularly useful when precise alignment between the clamp and the scooter surface is required. This direct manual intervention improves the intuitiveness of the operation and positioning accuracy. The handle also allows the operator to more directly perceive the contact between the clamp and the scooter, enhancing the controllability of the operation. This method is suitable for handling scenarios requiring manual positioning assistance.

[0015] Preferably, the guiding mechanism is a pulley.

[0016] Using pulleys as a guiding mechanism leverages their rolling friction to guide the wire rope in changing direction. The low coefficient of rolling friction between the pulley and the wire rope helps reduce frictional resistance caused by the rope's turning direction during transmission, allowing the cylinder's driving force to be transmitted more effectively to the end clamp, thus reducing energy loss. Lower friction also helps reduce wear on the wire rope surface, positively impacting its service life. As a standard component, the pulley is simple, reliable, and easy to install and maintain.

[0017] Preferably, a brake disc is provided at the rotating joint of the column.

[0018] A brake disc is installed at the rotating joint of the column, primarily to enhance the robotic arm's positioning and holding capabilities in the horizontal rotation direction. Once the robotic arm is adjusted to the predetermined working angle via the rotating joint, the brake disc is activated to generate braking torque, locking the rotating joint in its current position. This effectively prevents the cantilever portion of the robotic arm from unexpectedly rotating or drifting due to its own inertia or external disturbances, ensuring the positional stability of the entire boom system during the grasping, transporting, or placing of scooters, providing additional assurance for safe and accurate operation.

[0019] Preferably, the cylinder body is mounted on the secondary rocker arm via a mounting bracket.

[0020] The cylinder body is fixed to the secondary rocker arm using a specialized mounting bracket, providing structural flexibility and reliability. The mounting bracket can be independently designed according to the specific structure of the secondary rocker arm and the cylinder's mounting dimensions, achieving optimal force transmission path and spatial layout, avoiding the need to directly machine complex mounting interfaces onto the rocker arm body. This modular connection method makes the cylinder installation more stable and facilitates subsequent disassembly, maintenance, or replacement. The bracket design effectively distributes the reaction force of the cylinder during operation onto the secondary rocker arm.

[0021] Preferably, the free end of the wire rope is connected to a spring air tube, and the sponge suction cup clamp is connected to the spring air tube.

[0022] A spring-loaded air tube is connected between the free end of the steel wire rope and the sponge suction cup clamp. This design primarily serves the needs of the air circuit connection. The spring-loaded air tube itself has excellent extensibility and bending fatigue performance, enabling it to adapt to the lifting and lowering movement of the sponge suction cup clamp relative to the secondary swing arm under the traction of the steel wire rope. Its spiral structure can freely extend or retract with the lifting and lowering of the clamp, avoiding the bending, entanglement, or wear problems that easily occur in ordinary rigid air tubes or non-elastic hoses during repeated extension and retraction movements. This ensures that the air circuit to the sponge suction cup clamp is always unobstructed and reliable, thereby guaranteeing the stable realization of the adsorption function.

[0023] Preferably, the cylinder is an Airtac SC series cylinder.

[0024] Specifying Airtac SC series cylinders offers convenience and reliability. As common standardized pneumatic components, this series boasts relatively uniform and stable dimensional parameters, interface types, and performance indicators, facilitating both initial selection and subsequent procurement and stockpiling. Using mature standard parts helps ensure the cylinder's service life and operational reliability, reducing the risk of equipment downtime due to core drive component failures. Furthermore, standard cylinders offer good interchangeability; replacement procedures are relatively simple and quick, contributing to maintaining continuous production.

[0025] The advantages of this utility model compared to the prior art are: The pneumatic handling robotic arm for picking up and putting in a scooter from the box, as described in this utility model, exhibits some different technical characteristics through its specific component layout and transmission method.

[0026] A key feature of this robotic arm is the direct mounting of the drive cylinder onto the secondary swing arm, with steel cables transmitting the linear motion of the cylinder piston rod to the sponge suction cup gripper suspended at the end. This layout shortens the power transmission path between the drive and actuation components, allowing the cylinder's movement to more directly control the gripper's lifting and lowering motion. This directness contributes to improved end-effector response speed. Because the sponge suction cup gripper is suspended by flexible steel cables, rather than rigidly connected to the swing arm, it provides a certain amount of float when contacting the scooter surface. When the scooter surface has slight unevenness or the gripper angle is slightly off, this flexible connection allows the gripper to adaptively adjust its posture within a certain range, making it easier to achieve a full fit between the suction surface and the scooter surface. This is significant for ensuring reliable suction, effectively protecting the scooter's vulnerable surfaces, and adapting to uneven areas.

[0027] The use of pneumatic drive maintains the system's relatively simple power source and ease of maintenance. The multi-joint arm structure (including the column rotary joint, primary swing arm, intermediate rotary joint, and secondary swing arm) ensures the robotic arm has the necessary working range in the horizontal plane. Mounting the pneumatic control box on the primary swing arm brings the control unit closer to the drive cylinder, helping to optimize the air circuit layout and reduce pressure loss and response delay caused by long pipelines. The use of guiding mechanisms (such as pulleys) aims to ensure smooth wire rope steering while minimizing frictional resistance during transmission. A control handle allows for direct, precise manual control of the end effector. The introduction of a pressure-regulating filter helps improve air source quality, extending the lifespan and operational stability of pneumatic components. A brake disc provides a reliable locking function for the column rotary joint, enhancing the static stability of the robotic arm after positioning. The use of spring-loaded air hoses effectively solves the problem of adaptability to the expansion and contraction of the air circuit connection during lifting and lowering movements of the end effector.

[0028] Overall, this structural solution is specifically designed for scooter loading and unloading operations, providing a robotic arm solution that emphasizes directness, adaptability, and system simplicity at the end of the process, effectively improving the efficiency and safety of scooter packaging.

[0038] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0039] This embodiment provides a pneumatic handling robot arm for picking up and placing a scooter into a box, including a base 1, a column 2 fixedly installed on the base 1, a column rotation joint 3 set on the top of the column 2, a primary swing arm 4 with one end connected to the column rotation joint 3, an intermediate rotation joint 5 set on the end of the primary swing arm 4 away from the column rotation joint 3, a secondary swing arm 6 with one end connected to the intermediate rotation joint 5, a cylinder 7 whose cylinder body is hinged to the secondary swing arm 6, a transmission mechanism, and a sponge suction cup clamp 10 directly or indirectly installed on the free end of a steel wire rope 8. The sponge suction cup clamp 10 is used to adsorb the scooter 01. The transmission mechanism includes a steel wire rope and a guide mechanism. The guide mechanism is set on the secondary swing arm. One end of the steel wire rope is connected to the piston rod of the cylinder, and the other end passes around the guide mechanism and is connected to the sponge suction cup clamp 10.

[0040] This solution describes a pneumatic handling robot arm with a unique structural layout for picking up and placing scooters into a container. Its core feature is the direct hinge of a cylinder to a secondary swing arm, using a wire rope transmission mechanism to directly transmit the linear motion of the cylinder piston rod to a sponge suction cup gripper mounted on the free end of the wire rope. This design brings the drive unit closer to the end effector, allowing the cylinder's movement to be directly and quickly converted into the vertical lifting and lowering motion of the sponge suction cup gripper relative to the secondary swing arm. This direct drive method reduces intermediate transmission links, contributing to improved end-effector response speed. Because the sponge suction cup gripper is suspended by a wire rope, it possesses a certain degree of floating adaptability. When the gripper contacts the scooter surface, the flexibility of the wire rope allows for slight adjustments to its posture, making it easier to achieve a good fit with uneven scooter surfaces, improving the success rate and stability of the suction. The entire system still uses pneumatics as the primary power source, maintaining the characteristics of a simple pneumatic system structure and convenient maintenance. The secondary swing arm is connected to the primary swing arm via an intermediate rotary joint, and the primary swing arm is connected to the column via a column rotary joint. This multi-joint structure preserves a large range of motion for the robotic arm in the horizontal plane. The layout of the cylinder fixed to the secondary swing arm allows the power source for lifting operations to move with the work point, resulting in a relatively short force flow path. In summary, this structural design provides a handling approach that emphasizes rapid vertical lifting at the end of the lifting process and adaptive centering.

[0041] The cylinder body of cylinder 7 is hinged to one end of the near-central rotary joint 5 of the secondary rocker arm 6 via a mounting bracket.

[0042] In this embodiment, the adsorption surface of the sponge suction cup clamp is a rectangular plane.

[0043] The suction cup clamp's rectangular suction surface is particularly well-suited for transporting scooters, as it adheres well to scooter pedals and other components with large, flat surfaces. The rectangular suction surface provides a wider, continuous suction area than a circular suction surface of the same size, increasing the effective contact area with the scooter and thus improving the grip, reducing the risk of slippage during transport. The rectangular edge shape also makes it easier for the operator to visually align the scooter's corners for more precise positioning. This shape is also well-suited for regularly shaped scooters.

[0044] In this embodiment, a pneumatic control box 11 is also included. The pneumatic control box 11 is mounted on the first-stage swing arm and connected to the cylinder via an air pipe.

[0045] Placing the pneumatic control box on the primary swing arm is a solution for locating control components close to the system. This arrangement shortens the air pipe connection length between the control box and the cylinder mounted on the secondary swing arm, reducing pressure loss along the pipe and helping to ensure more efficient air pressure transmission to the cylinder. The shorter pipe layout also simplifies the piping routing, potentially reducing the risk of interference with other moving parts due to excessive pipe length. Centralized installation of the control box facilitates the integration of pneumatic components such as pressure regulators and reversing devices, making system maintenance and inspection more focused.

[0046] In this embodiment, a pressure regulating water filter 13 is provided in the air circuit of the air control box.

[0047] Integrating a pressure-regulating filter into the air circuit of the pneumatic control box plays a crucial role in maintaining the stable and reliable operation of the pneumatic system. The pressure-regulating filter removes impurities such as moisture, oil mist, and small solid particles carried in the compressed air, providing cleaner and drier working gas to the cylinder. This helps reduce wear and corrosion caused by impurities on the cylinder's inner wall and seals, thereby extending the cylinder's service life. Its pressure-regulating function stabilizes the working pressure supplied to the cylinder, preventing unstable output force or uneven movement speed of the robotic arm due to fluctuations in air source pressure, ensuring consistent handling actions. The pneumatic control box 11 is connected to an external air source via air pipes and provides power to the cylinder 7 and the sponge suction cup clamp 10.

[0048] In this embodiment, a control handle 12 is also included, which is connected to the sponge suction cup clamp.

[0049] The control handle, directly connected to the foam suction cup clamp, provides the operator with a direct way to control the end effector. The operator can fine-tune the position and orientation of the foam suction cup clamp using the handle, which is particularly useful when precise alignment between the clamp and the scooter surface is required. This direct manual intervention improves the intuitiveness of the operation and positioning accuracy. The handle also allows the operator to more directly perceive the contact between the clamp and the scooter, enhancing the controllability of the operation. This method is suitable for handling scenarios requiring manual positioning assistance.

[0050] In this embodiment, the guiding mechanism is a pulley.

[0051] Using pulleys as a guiding mechanism leverages their rolling friction to guide the wire rope in changing direction. The low coefficient of rolling friction between the pulley and the wire rope helps reduce frictional resistance caused by the rope's turning direction during transmission, allowing the cylinder's driving force to be transmitted more effectively to the end clamp, thus reducing energy loss. Lower friction also helps reduce wear on the wire rope surface, positively impacting its service life. As a standard component, the pulley is simple, reliable, and easy to install and maintain.

[0052] In this embodiment, a brake disc 14 is provided at the column rotation joint.

[0053] A brake disc is installed at the column rotation joint, primarily to enhance the robotic arm's positioning and holding capabilities in the horizontal rotation direction. Once the robotic arm is adjusted to the predetermined working angle via the rotation joint, the brake disc is activated to generate braking torque, locking the rotation joint in its current position. This effectively prevents the cantilever portion of the robotic arm from unexpectedly rotating or drifting due to its own inertia or external interference, ensuring the positional stability of the entire boom system during the grasping, transporting, or placing of scooters, providing additional assurance for safe and accurate operation. It should be noted that the column rotation joint 3 and the intermediate rotation joint 5 are manually operated joints, adjusted for horizontal position by the operator pushing the swing arm, and locked in place via the brake disc 14.

[0054] In this embodiment, the cylinder body is mounted on the secondary rocker arm via a mounting bracket.

[0055] The cylinder body is fixed to the secondary rocker arm using a specialized mounting bracket, providing structural flexibility and reliability. The mounting bracket can be independently designed according to the specific structure of the secondary rocker arm and the cylinder's mounting dimensions, achieving optimal force transmission path and spatial layout, avoiding the need to directly machine complex mounting interfaces onto the rocker arm body. This modular connection method makes the cylinder installation more stable and facilitates subsequent disassembly, maintenance, or replacement. The bracket design effectively distributes the reaction force of the cylinder during operation onto the secondary rocker arm.

[0056] In this embodiment, the free end of the wire rope is connected to a spring air tube 9, and the sponge suction cup clamp is connected to the spring air tube 9.

[0057] A spring-loaded air tube is connected between the free end of the steel wire rope and the sponge suction cup clamp. This design primarily serves the needs of the air circuit connection. The spring-loaded air tube itself has excellent extensibility and bending fatigue performance, enabling it to adapt to the lifting and lowering movement of the sponge suction cup clamp relative to the secondary swing arm under the traction of the steel wire rope. Its spiral structure can freely extend or retract with the lifting and lowering of the clamp, avoiding the bending, entanglement, or wear problems that easily occur in ordinary rigid air tubes or non-elastic hoses during repeated extension and retraction movements. This ensures that the air circuit to the sponge suction cup clamp is always unobstructed and reliable, thereby guaranteeing the stable realization of the adsorption function.

[0058] In this embodiment, the cylinder is an Airtac SC series cylinder.

[0059] Specifying Airtac SC series cylinders offers convenience and reliability. As common standardized pneumatic components, this series boasts relatively uniform and stable dimensional parameters, interface types, and performance indicators, facilitating both initial selection and subsequent procurement and stockpiling. Using mature standard parts helps ensure the cylinder's service life and operational reliability, reducing the risk of equipment downtime due to core drive component failures. Furthermore, standard cylinders offer good interchangeability; replacement procedures are relatively simple and quick, contributing to maintaining continuous production.
