Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a cylinder-balanced pneumatic motor lifting robotic arm. Background Technology

[0002] In automated production lines, robotic arms are core equipment for material handling and are widely used in operations such as workpiece gripping, lifting, and transporting. Among these, the lifting stability, load adaptability, and energy consumption level of lifting robotic arms directly affect production efficiency and operational accuracy. Existing lifting robotic arms have at least the following drawbacks: 1. Existing lifting robotic arms experience pauses during lifting when the load is large, especially when using individual lifting cylinders; 2. Existing lifting robotic arms require manual pulling for balancing individual cylinders, which is laborious. Therefore, we have introduced a new cylinder-balanced pneumatic motor lifting robotic arm.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A cylinder-balanced pneumatic motor lifting robot includes a lifting body 1. A fixed frame 5 is fixedly connected to the right end of the lifting body 1. A pneumatic motor 2 is fixedly connected to the lower rear end of the fixed frame 5. A control button 10 is provided on the outer surface of the pneumatic motor 2. A gear 3 is fixedly connected to the part of the output end of the pneumatic motor 2 that passes through the fixed frame 5. A rack 4 is provided on the inner side of the lifting body 1. A base 6 is fixedly connected to the lower end of the rack 4. A support frame 7 and a connecting frame 8 are fixedly connected to the left end of the base 6, and the connecting frame 8 is located on the upper side of the support frame 7. In this embodiment, the inner walls of the support frame 7 and the connecting frame 8 are jointly provided with a chain 9, and the chain 9 is sleeved with the lifting body 1. The middle of the left end and the middle of the right end of the lifting body 1 are both provided with strip grooves 15. The upper end of the lifting body 1 is fixedly connected to a top plate 11. The four corners of the upper end of the top plate 11 are all connected with No. 1 connecting screws 12. The outer surface of the gear 3 is meshed with a driven wheel 14, and the driven wheel 14 is connected to the lifting body 1. Several No. 2 positioning screws 13 are connected longitudinally at equal intervals on the right end of the fixing frame 5. The several No. 2 positioning screws 13 all pass through the fixing frame 5 and are connected to the lifting body 1. The four No. 1 connecting screws 12 all pass through the top plate 11 and are connected to the lifting body 1.

[0017] The above scheme allows the chain 9 to drive the lifting process of the lifting body 1. The support frame 7 and the connecting frame 8 together support and protect the chain 9 during use. The pneumatic motor 2 drives the gear 3 to rotate, which in turn drives the driven wheel 14 to rotate, thereby adjusting the height of the lifting body 1 and completing the lifting and lowering of the lifting body 1.

[0018] It should be noted that this utility model is a cylinder-balanced pneumatic motor lifting robot. During use, the top plate 11 is first positioned. Four No. 1 connecting screws 12 are evenly inserted through the top plate 11 and connected to the lifting body 1. This connection method acts like a stable bridge between the top plate 11 and the lifting body 1, firmly fixing the top plate 11 in the appropriate position, effectively improving the stability of the entire robot structure and providing a solid foundation for subsequent lifting operations. This ensures that the top plate 11 will not shake or shift during lifting. The control button 10 is the control switch for the entire robot operation. The operator sends a control signal to the pneumatic motor 2 by pressing or operating the control button 10. After receiving the signal, the pneumatic motor 2 starts running, converting the pressure energy of compressed air into mechanical energy, driving the connected gear 3 to rotate. The gear 3 acts as the power transmission hub of the robot, transmitting the power of the pneumatic motor 2 to provide power support for subsequent lifting actions. The driven wheels 14 are connected by a meshing mechanism. When the gear 3 rotates under the drive of the pneumatic motor 2, its teeth mesh with the teeth of the driven wheels 14, thereby driving the driven wheels 14 to rotate synchronously. The rotation of the driven wheels 14 is not isolated; it is closely connected to the height adjustment mechanism of the lifting body 1. Through the rotation of the driven wheels 14, the height of the lifting body 1 can be adjusted. For example, when the driven wheels 14 rotate clockwise, a series of mechanical structures may be used to raise the lifting body 1; conversely, counterclockwise rotation will raise the lifting body 1. The chain 9 descends to complete the lifting and lowering function of the entire cylinder. The chain 9 plays an important driving role in the lifting and lowering process of the lifting body 1. It is like a tough "transmission belt" connected to the lifting body 1. As the driven wheel 14 rotates, the chain 9 starts to move, thereby driving the lifting body 1 to rise and fall in the predetermined direction. At the same time, the support frame 7 and the connecting frame 8 together form the support and protection system of the chain 9. The support frame 7 provides a stable support point for the chain 9, ensuring that the chain 9 will not sag or loosen during the movement.The connecting frame 8 connects the support frame 7 to other components, forming a complete structure. This further enhances the support and protection for the chain 9, improving the stability of the entire lifting process. The balanced air path is crucial for the robot's smooth lifting. By designing the balanced air path, the lifting body 1 is adjusted to a floating state, ensuring balanced air pressure on both sides. Under heavy loads, the floating movement of the lifting body 1 requires significant pulling force. At this point, the pneumatic motor 2 plays a vital role, driving the gear 3 and rack 4 to work together. The rack 4 is connected to the lifting body 1; when the gear 3 rotates, it drives the rack 4 in a linear motion, thus lifting the lifting body 1. The speed and direction of the pneumatic motor 2 can be precisely controlled via a button, allowing for precise control of the gear 3 and rack 4, resulting in uniform lifting speed. This design effectively avoids sudden stops or inability to lift, further improving the robot's stability. It saves manpower and solves the problem of potential stops in traditional lifting methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
