Pulley type stacking mechanical arm

Abstract

The invention relates to the field of stacking machines, in particular to a pulley type stacking mechanical arm. The pulley type stacking mechanical arm comprises a base plate, a base, a support, a supporting column, a hydraulic arm, a movable arm, a pulley, a balance block and a pull rope. The base comprises a fixed base body arranged on the base plate and a rotary base body arranged on the fixed base body. The support is fixed to the base. The supporting column is vertically fixed to the rotary base body. The two ends of the hydraulic arm are hinged to the supporting column and the movable arm correspondingly. The pulley comprises an active rolling wheel and a fixed pulley body, the active rolling wheel and the fixed pulley body are arranged on the support, and the side face of the active rolling wheel is connected with a motor. One end of the pull rope is fixed to the other end of the movable arm, the middle portion of the pull rope winds across the fixed pulley body, and the other end of the pull rope is wound on the active rolling wheel by a plurality of circles. The balance block is connected with the other end of the pull rope and arranged in a suspended mode. According to the pulley type stacking mechanical arm, the rope and the pulley are used for force transmission, and the stress difference between the two ends of the rope is made smaller so that the output torque of the driving motor can be smaller when the mechanical arm moves, and the mechanical arm can save more energy.

Description

technical field [0001] The invention relates to the field of palletizing machinery, in particular to a pulley type palletizing mechanical arm. Background technique [0002] At present, in the field of industrial automation production, various special machines or mechanical arms are used to carry and stack materials to improve operating efficiency and overall productivity. According to the different conditions of the production line and the volume and weight of the material, these devices have different shapes. Compared with special-purpose machines, robotic arms have been widely used in the field of material handling and stacking due to their small footprint, simple structure, flexible operation, and flexible operations. The structural forms of the manipulator are more representative, such as the general-purpose articulated industrial manipulator, or the SCARA-shaped plane coordinate manipulator, etc. [0003] The above robotic arms have a common problem. Even when the rob...

Problems solved by technology

[0003] The above robotic arms have a common problem. Even when the robotic arm is empty, as long as the robotic arm moves, it still needs to consume a lot of energy for the movement of the robotic arm itself. Therefore, the smaller the mass of the cargo carried by the robotic arm, the more The less efficient the use of energy
