Description

Technical Field

[0001] The present invention relates to the technical field of mechanical arms, and in particular to a mechanical arm with an anti-falling component. Background Art

[0002] A robotic arm with an anti-fall component is an automated device that adds a specially designed anti-fall component to a traditional robotic arm. It is usually composed of multiple joints and connecting rods, and can imitate the movement of human arms to achieve various complex grasping, carrying, operating and other tasks. The anti-fall component is a specific structure or device designed to ensure that the robotic arm can effectively prevent objects from accidentally falling off when grasping them.

[0003] When a robotic arm with an anti-fall component is working, it slowly approaches the target object to ensure that it can accurately align with the center of the object before grasping it. The end effector of the robotic arm (such as a gripper or suction cup) performs the grasping action. At this time, the anti-fall component ensures that the object will not accidentally slip during clamping. After the grasping is completed, the robotic arm will confirm whether the object is successfully clamped through sensors and check whether the anti-fall component is working properly. After confirming that the grasping is stable, the robotic arm can move to the designated position to complete the handling or other tasks. After completing the target position, the robotic arm will execute the release action, while ensuring that the anti-fall component will not cause damage to the object during the release process.

[0004] However, the shape, material and structure of the robotic arm clamp may not be suitable for a specific object. Improper design will lead to uneven clamping or failure to effectively adapt to the shape of the object, making it difficult to ensure uniform distribution of clamping force, causing the object to be subjected to unbalanced force when clamped. The movement of the T-plate is also difficult to stabilize, and may shake or deviate, making it difficult to ensure that the clamp block and rubber pad can accurately approach the object and achieve reliable clamping. Therefore, a robotic arm with an anti-fall-off component is proposed to solve these problems. Summary of the invention

[0016] Working principle and working process of the present invention: In the initial state, each component is in a non-working position, the power telescopic rod is in a retracted state, the clamping block of the clamping mechanism does not clamp the object, and the fixing hook of the locking mechanism is not connected to the fixing column; When it is necessary to clamp an object, the power telescopic rod is started to retract, and the power telescopic rod pushes the transmission gear plate to slide in the fixed frame. The movement of the transmission gear plate drives the rotating gears on both sides to rotate, and the rotating gears drive the T-plate to move through the connecting rod. The T-plate pushes the clamping block and the rubber pad to approach the object to achieve clamping of the object; When the power telescopic rod moves, the limit sleeve moves in a direction away from the fixed frame. When the limit sleeve moves to a certain position, the first rack plate drives the rotating gear to rotate, and the rotating gear drives the second rack plate to move, so that the fixed hook approaches the fixed column. When the fixed hook contacts the fixed column, the fixed hook tightly hooks the fixed column under the action of the spring, thereby locking the power telescopic rod and maintaining the clamping state. When the object needs to be rotated, the driver drives the transmission rod to rotate, the transmission rod drives the rotating column to rotate, the rotating column cooperates with the base to rotate the object, and at the same time, the driving motor drives the second gear to rotate, and the second gear drives the first gear to rotate, thereby further adjusting the rotation angle of the object.

[0017] Beneficial effects of the present invention: The present invention provides a clamping mechanism and a transmission tooth plate and other structures to cooperate so that the clamping process of the mechanical arm is stable and reliable. When it is necessary to clamp an object, the power telescopic rod is started to contract, and the power telescopic rod pushes the transmission tooth plate to slide in the fixed frame. The movement of the transmission tooth plate drives the rotating gears on both sides to rotate, and the rotating gear drives the T-plate to move through the connecting rod. The T-plate pushes the clamping block and the rubber pad to approach the object to achieve clamping of the object, and the transmission tooth plate slides in the fixed frame, providing a stable guide for the entire clamping process, and the rotating gears on both sides rotate at the same time to ensure uniform distribution of the clamping force, so that the object is subjected to a more balanced force when being clamped, and the movement of the T-plate is also more stable without shaking or deviation, thereby ensuring that the clamping block and the rubber pad can accurately approach the object and achieve reliable clamping. This stable and reliable clamping process can greatly improve work efficiency and safety, and reduce accidents and work errors caused by unstable clamping.

[0018] The present invention is provided with structures such as a limit sleeve and a locking mechanism. When the power telescopic rod moves, the limit sleeve moves in a direction away from the fixed frame. When the limit sleeve moves to a certain position, the first rack plate drives the rotating gear to rotate, and the rotating gear drives the second rack plate to move, so that the fixing hook is close to the fixing column. When the fixing hook contacts the fixing column, under the action of the spring, the fixing hook tightly hooks the fixing column to achieve locking of the power telescopic rod and maintain the clamping state. After the power telescopic rod pushes the transmission tooth plate to achieve clamping, the power telescopic rod is locked by the linkage of the limit sleeve, the first rack plate, the rotating gear, the second rack plate and the fixing hook, which can effectively prevent the power telescopic rod from loosening or retracting due to external force interference during operation, thereby ensuring the long-term stability of the clamping state. The entire locking process is automatically triggered with the movement of the power telescopic rod, and no additional manual operation is required. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] A mechanical arm with an anti-falling component, comprising a guide plate 1 and a fixing frame 2, and further comprising: A power telescopic rod 3, which is located inside the guide plate 1; A transmission gear plate 4, which is fixedly mounted on one end of the power telescopic rod 3; The clamping mechanism 5 is provided with two groups, and the two groups of clamping mechanisms 5 are respectively located on both sides of the transmission gear plate 4; A limiting sleeve 6, the limiting sleeve 6 is fixedly connected to one end of the power telescopic rod 3 close to the transmission gear plate 4; A locking mechanism 7, which is arranged on one side of the limiting sleeve 6; A bracket 8, two sides of which are connected to the outer surfaces of two sides of the guide plate 1; A rotating block 9, one end of which is connected to the inside of the bracket 8; The clamping mechanism 5 includes a rotating gear 51, a connecting rod 52, a T-shaped plate 53, a clamping block 54 and a rubber pad 55. The rotating gear 51 is fixedly connected to one end of the connecting rod 52, the other end of the connecting rod 52 is rotatably connected to the T-shaped plate 53 through a rotating sheet, one side of the T-shaped plate 53 is connected to one side of the clamping block 54, and the other side of the clamping block 54 is fixedly connected to the rubber pad 55. The locking mechanism 7 includes a first rack plate 71 fixedly connected to one side of the limiting sleeve 6, a rotating gear 72 meshing with the first rack plate 71, a second rack plate 73 meshing with the rotating gear 72, and a fixing hook 74 fixedly connected to one end of the second rack plate 73.

[0023] The above scheme is adopted: the guide plate 1 and the fixed frame 2 provide stable support for the bracket 8, so that the bracket 8 can be firmly fixed on the guide plate 1, thereby ensuring the stable operation of the rotating block 9. The guide plate 1 is relatively connected to the fixed frame 2 to form an integral structure, which improves the stability and strength of the entire device. At the same time, this connection method also provides a basis for the installation of other components. The transmission gear plate 4 is pushed to move in the fixed frame 2 through telescopic movement. When the power telescopic rod 3 is extended, the power can be transmitted to the transmission gear plate 4, so that the transmission gear plate 4 moves in the direction of the clamping mechanism 5, thereby driving the clamping mechanism 5 to clamp the object. The telescopic length can be adjusted according to the size and clamping requirements of different objects to achieve clamping operations on different objects. It has adjustability and can adapt to different working scenes. By setting the coordination of structures such as the clamping mechanism 5 and the transmission gear plate 4, the clamping process of the robot arm is stable and reliable. When it is necessary to clamp an object, the power telescopic rod 3 is started to contract, and the power telescopic rod 3 pushes the transmission toothed plate 4 to slide in the fixed frame 2. The movement of the transmission toothed plate 4 drives the rotating gears 51 on both sides to rotate, and the rotating gears 51 drive the T-plate 53 to move through the connecting rod 52. The T-plate 53 pushes the clamping block 54 and the rubber pad 55 to approach the object to achieve clamping of the object. The transmission toothed plate 4 slides in the fixed frame 2, providing a stable guide for the entire clamping process. The rotating gears 51 on both sides rotate at the same time, ensuring the uniform distribution of the clamping force, so that the object is subjected to a more balanced force when being clamped, and the movement of the T-plate 53 is also more stable without shaking or offset, thereby ensuring that the clamping block 54 and the rubber pad 55 can accurately approach the object and achieve reliable clamping. This stable and reliable clamping process can greatly improve work efficiency and safety, and reduce accidents and work errors caused by unstable clamping.

[0024] like Figures 1 to 8As shown, the guide plate 1 and the fixed frame 2 are connected to each other on opposite sides, the top of the guide plate 1 is fixedly connected with a connecting plate, and the connecting plate is arc-shaped, the bottom surface of one end of the connecting plate is connected to the top surface of the rotating block 9, the bottom surface of the fixed frame 2 is provided with a groove, and the size of the groove is adapted to the limit sleeve 6, the end of the guide plate 1 close to the bracket 8 is fixedly connected with a short plate 101, the side of the short plate 101 facing the clamping mechanism 5 is fixedly connected to the other end of the power telescopic rod 3, and one end of the power telescopic rod 3 is connected to the transmission tooth plate 4 through a gasket, and the transmission tooth plate 4 is located inside the fixed frame 2. The top and bottom of the rotating gear 51 are both rotatably connected to the inner wall of the fixed frame 2 through a rotating shaft. One end of the T-plate 53 is rotatably connected to a toggle rod 56. The top and bottom of the toggle rod 56 are also rotatably connected to the inner wall of the fixed frame 2 through a rotating shaft. The distance between the toggle rod 56 and the transmission tooth plate 4 is greater than the distance between the connecting rod 52 and the transmission tooth plate 4. The limiting sleeve 6 passes through the guide plate 1 and is connected to one end of the first rack plate 71. The top of the rotating gear 72 is fixedly connected to a rotating rod, and one end of the rotating rod is rotatably connected to the bottom of the rotating block 9.

[0025] The above scheme is adopted: the transmission tooth plate 4 plays a key transmission role in the device, is fixedly connected with the power telescopic rod 3, and transmits the power of the power telescopic rod 3 to the clamping mechanism 5. When the power telescopic rod 3 pushes the transmission tooth plate 4 to move, the teeth on the transmission tooth plate 4 mesh with the rotating gear 51, driving the rotating gear 51 to rotate. By meshing with the rotating gear 51, the linear motion of the power telescopic rod 3 is converted into the rotational motion of the rotating gear 51, thereby realizing the clamping and releasing operations of the clamping mechanism 5. It is located inside the fixed frame 2 and is slidably connected to the fixed frame 2. This design ensures the stability and accuracy of the transmission tooth plate 4 during movement, and avoids shaking or deviation from the track. Through the arrangement of structures such as the limit sleeve 6 and the locking mechanism 7, when the power telescopic rod 3 moves, the limit sleeve 6 moves in the direction away from the fixed frame 2. When the limit sleeve 6 moves, the limit sleeve 6 moves in the direction away from the fixed frame 2.

[0026] like Figures 1 to 8As shown, the other end of the second rack plate 73 is fixedly connected to a spring 731, one end of the spring 731 is fixedly connected to a stabilizing block, and the top surface of the stabilizing block is connected to the bottom surface of the guide plate 1, the bottom of the rotating block 9 is also fixedly connected to a fixing column 91, the fixing column 91 is adapted to the fixing hook 74, and the bottom end of the fixing column 91 is fixedly connected to a stopper, the top of the rotating block 9 is fixedly connected to a support frame 92 through a mounting plate, the bottom surface of one end of the support frame 92 is fixedly connected to a short arm through an inclined block, and one end of the short arm is connected to the other end of the rotating block 9, and a vertical plate 93 is installed at the other end of the short arm, and a base 94 is fixedly installed at the bottom of the vertical plate 93, and the surface of the base 94 is rotatably connected to A card plate 95, a driver is fixedly installed on the back of the card plate 95, the output end of the driver is splined with a transmission rod, and one end of the transmission rod is fixedly connected to a rotating column, the outer rings at both ends of the rotating column are rotatably connected to the card plate 95 through bearings, and the surface of the rotating column is connected to the base 94, the bottom surface of the card plate 95 is rotatably connected to the first gear 951 through a rotating shaft, and the first gear 951 is meshed with the second gear 952, a driving motor 953 is fixedly installed on one side of the card plate 95 through a stabilizing plate, the output end of the driving motor 953 is connected to the second gear 952, and the bottoms of the first gear 951 and the second gear 952 are rotatably connected to a mounting base plate 954 through a rotating shaft.

[0027] The above scheme is adopted: the rotating gear 51 is one of the core components of the clamping mechanism 5, the rotating gear 51 is engaged with the transmission gear plate 4, the linear motion of the transmission gear plate 4 is converted into its own rotational motion, and the rotating gear 51 and the T-plate 53 are connected to play the role of transmitting power. When the rotating gear 51 rotates, the connecting rod 52 drives the T-plate 53 to move, so that the clamping block 54 and the rubber pad 55 clamp or release the object.

When the fixing hook 74 contacts the fixing column 91, under the action of the spring 731, the fixing hook 74 tightly hooks the fixing column 91, thereby locking the power telescopic rod 3 and maintaining the clamping state. When the object needs to be rotated, the driver drives the transmission rod to rotate, the transmission rod drives the rotating column to rotate, the rotating column cooperates with the base 94 to rotate the object, and at the same time, the driving motor 953 drives the second gear 952 to rotate, and the second gear 952 drives the first gear 951 to rotate, thereby further adjusting the rotation angle of the object.
