An adjustable planar robotic arm with electric grippers

Abstract

The invention provides an adjustable planar mechanical arm with an electric clamping jaw. The adjustable planar mechanical arm with the electric clamping jaw has the advantages that driving componentsare arranged on a bottom platform, and a first arm and a second arm are free of extra weights except for the weights of the first arm and the second arm and the weights of matched connecting rods; the lengths of the first arm and the second arm can be adjusted, and accordingly the adjustable planar mechanical arm is excellent in adaptability for different working conditions; a driving component of the electric clamping jaw is arranged outside a clamping jaw body, and accordingly load on the second arm is light; the clamping jaw is driven by a motor and is low in impact force and free of influence on movement of the adjustable planar mechanical arm; the adjustable planar mechanical arm is high in tail-end movement speed and repeat positioning accuracy, excellent effects can be realized forquick operation on robots, and the like.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an adjustable planar 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. On the other hand, the arm length of most articulated robots is not adjustable, which is not conducive to making changes to the working environment. [0003] It is common to use robots for clamping o...

Problems solved by technology

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

On the other hand, the arm length of most multi-joint robots is not adjustable, which is not conducive to making changes to the working environment

[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
