Industrial robot

Abstract

The invention relates to an industrial robot. The industrial robot structurally comprises a mechanical arm and a handheld programmer. The mechanical arm is provided with six rotating shafts, a series structure is adopted, and each rotating shaft is composed of a stepping motor, a precision speed reducer and a precision bearing. An electromagnetic chuck connector is arranged at the front end of the mechanical arm, and therefore automatic replacement of various end execution mechanisms can be achieved. A motion controller is composed of an embedded processor, rotating shaft motion, linear motion, arc motion and the like can be achieved, external shafts are supported, and the repeated locating precision is smaller than 0.1 mm. The motion controller and a motor power drive circuit can be completely embedded into the mechanical arm, and no external control cabinet is needed. Wiring of the mechanical arm and the handheld programmer is simple, and only a power line and a serial data bus are needed. Power supply at the low voltage ranging from 12 V to 24 V is achieved, and the industrial robot is especially suitable for being mounted on field mobile equipment or used in the underwater work environment.

Description

technical field [0001] The invention relates to an industrial robot. Background technique [0002] Industrial robots are widely used in the manufacturing industry, and their working performance exceeds that of humans in all aspects. They have become an indispensable tool for industrial production. However, there are still some problems in the current industrial robots that limit its wider application. For example, the use of servo motors requires 200V high voltage, which is not safe for outdoor operation, and is not suitable for battery power supply; the servo control system is complex and expensive, difficult to miniaturize, and difficult to embed in In the robotic arm; the learning, programming, operation process is complex, etc. These are the extra burdens caused by excessive pursuit of the perfect performance of the servo motor, thus limiting the application field and scope of general-purpose industrial robots. For example, the movement of the mechanical arm equipped o...

However, there are still some problems in the current industrial robots that limit its wider application. For example, the use of servo motors requires 200V high voltage, which is not safe for outdoor operation, and is not suitable for battery power supply; the servo control system is complex and expensive, difficult to miniaturize, and difficult to embed in In the robotic arm; the learning, programming, operation process is complex, etc.

These are the extra burdens caused by too much pursuit of the perfect performance of servo motors, thus limiting the application fields and scope of general-purpose industrial robots

For example, the movement of the mechanical arm equipped on the battery-powered field mobile robot can only be simple and clumsy, while the dexterous and high-performance industrial robot is difficult to install because of high voltage, can not withstand rain and humidity, consumes a lot of power and cannot last for a long time.
