Application of industrial manipulator in automatic production line
The industrial manipulator can complete various expected tasks through programming,and has the advantages of both human and machine in structure and performance,especially reflecting human intelligence and adaptability.The accuracy of manipulator operation and the ability to complete the operation in various environments have broad prospects for development in various areas of the national economy.
Electric drive is one of the most widely used driving methods for manipulators.It is characterized by convenient power supply,fast response,large driving force(the weight of joint type has reached 400kg),convenient signal detection,transmission and processing,and can adopt a variety of flexible control schemes.Stepping motor is generally used as the driving motor,and DC servo motor(AC)is the main driving mode.Due to the high speed of the motor,the reduction mechanism(such as harmonic drive,RV cycloidal pin wheel drive,gear drive,screw drive and multi bar mechanism)must be used.Some manipulators have begun to use high torque,low speed motors without reduction mechanisms for direct drive(DD),which can simplify the mechanism and improve the control accuracy.
Manipulator is a new device developed in the process of mechanization and automation.In the modern production process,the manipulator is widely used in the automatic production line.The development and production of robot has become a new technology rapidly developed in the high-tech field.It has further promoted the development of the manipulator,enabling it to better realize the organic combination with mechanization and automation.Although the manipulator is not as flexible as the human hand,it has the characteristics of being able to repeatedly work and work,not knowing fatigue,not afraid of danger,and more powerful than the human hand in lifting heavy objects.Therefore,the manipulator has been attached importance to by many departments,and has been more and more widely used.
