Abstract

The invention relates to a low-cost modularized SCARA robot and aims at providing a robot having the advantages of being simple in structure, low in cost and modularized. According to the technical scheme, the low-cost modularized SCARA robot comprises a machine base, a motor set, a big arm, a small arm, a tail end shaft and a transmission mechanism, wherein the motor set is arranged inside the machine base, the big arm is capable of rotating around a vertical axis and is located on the machine base, the small arm is capable of rotating around the vertical axis and is located at the front end of the big arm, the tail end shaft is capable of rotating around the vertical axis and is located at the front end of the small arm, and the transmission mechanism is used for transmitting power of the motor set for driving the big arm, the small arm and the tail end shaft to move; the robot is characterized in that the machine base, the big arm and the small arm are assembled into a machine base module, a big arm module and a small arm module through multiple assembling units respectively, and the whole machine of the low-cost modularized SCARA robot can be assembled through the machine base module, the big arm module and the small arm module which are connected through screws.

Description

technical field [0001] The invention relates to the technical field of SCARA robots, in particular to a low-cost, modularized SCARA robot. Background technique [0002] The SCARA robot is a cylindrical coordinate industrial robot with high work efficiency and reliable operation, and is widely used in the assembly industry. However, the price remains high. Traditional SCARA robots are equipped with three sets of servo motors and reducers on the upper arm and the lower arm. Therefore, the mass of the moving part is large, and the mechanical and control systems of the robot are very demanding when realizing high-speed and high-precision movement. , resulting in high machine cost and maintenance cost. Therefore, reducing the mass of moving parts and modularizing the whole machine are effective ways to reduce the overall cost of SCARA robots. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the above-mentioned backgrou...
