Four-joint robot

Abstract

The invention discloses a four-joint robot. The four-joint robot comprises a base, wherein a first-axis speed reducer and a first-axis motor are arranged at the upper end of the base, the first-axis speed reducer is connected with a first-axis joint, and a second-axis speed reducer is arranged at the upper end of the first-axis joint; a second-axis motor is arranged on one side of the second-axisspeed reducer, a two-joint mechanical arm is arranged at the upper end of the second-axis speed reducer, and a third-axis speed reducer is arranged at the upper end of the two-joint mechanical arm; athird-axis motor is arranged at one end of the third-axis speed reducer, a third-axis mechanical arm is arranged at the right end of the third-axis speed reducer, and a fourth-axis speed reducer is arranged at the right end of the third-axis mechanical arm; a fourth-axis joint is arranged at the upper end of the fourth-axis speed reducer, and a fourth-axis motor is arranged on one side of the fourth-axis speed reducer; and universal wheels are arranged at the lower end of the base, auxiliary rollers are arranged on two sides of the base, and a scanner is connected to the bottom end of the fourth-axis speed reducer. The universal wheels and the auxiliary rollers facilitate the automatic movement of the robot, the functional diversity of the robot is increased through the scanner, and the four-joint robot is suitable for the express industry and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a four-joint robot. Background technique [0002] With the popularization and application of industrial automation and the continuous rise of labor costs, robots have been widely used in various industrial environments, which greatly improved the quality of products while reducing the cost of enterprises. There are many types of robots, but six-axis robots occupy a large market share due to their superior versatility and flexibility. This is most obvious in the spraying and welding industries. With the support of local and national policies, more and more domestic enterprises have entered the robot industry. However, so far, most of the four-joint robots have heavy weight and insufficient rigidity of the mechanical arm, high torque and power of the motor, short service life of the motor, high energy consumption, and poor overall operation of the robot. So convenient and flexi...
