A multi-axis robotic arm with electric gripper

Abstract

The invention provides a multi-axis mechanical arm with electric grippers. The driving element is arranged on the platform at the bottom. The first arm and the second arm have no additional weight except their own weight and the weight of the supporting connecting rod, and have the advantages of It has the characteristics of fast movement of the end; the end of the second arm is equipped with a working end that can rotate and rotate, which has a greater degree of freedom of movement and can meet various operating requirements; the driving components for the rotation and rotation of the working end are also installed On the platform, the weight of the moving part is lighter than that of the existing mechanical arm module, especially suitable for the fast-moving operation of the working end; the driving part of the electric gripper is arranged outside the gripper body, which further reduces the load of the second arm; The claw body realizes clamping and screwing actions in a small volume, which has good practicability.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a multi-axis mechanical arm with electric grippers. Background technique [0002] Robots can be divided into parallel robots and serial robots. Among them, the common type of serial robots is articulated robots. In common articulated robots, the driving components of each arm are installed on the joints connected to the forearm. As the number of arms increases, the load on each arm will increase accordingly, resulting in an increase in the volume of the driving power components of the arm and an increase in the movement speed of the arm. Problems such as slowing down and reducing the accuracy of the arm are not conducive to the high-speed and miniaturization of joint robots. [0003] It is common to use robots for clamping operations in robot applications. Common clamping tools use air pressure as the driving force. When the clamping tool starts or stops, it will generate a large...

In common articulated robots, the driving components of each arm are installed on the joints connected to the forearm. As the number of arms increases, the load on each arm will increase accordingly, resulting in an increase in the volume of the driving power components of the arm and an increase in the movement speed of the arm. Problems such as slowing down and reducing the accuracy of the arm are not conducive to the high-speed and miniaturization of joint robots

[0003] It is common to use robots for clamping operations in robot applications. Common clamping tools use air pressure as the driving force. When the clamping tool starts or stops, it will generate a large impact force, which is easy to cause damage to high-speed robots with small loads. The impact makes its motion coordinates change, which is not conducive to the repeated positioning of the robot; some clamping tools are also driven by motors, but the motor and clamping tools are often integrated, and the weight is heavy, which is not conducive to the high-speed movement of the robot
