Embodiment Construction

[0017] figure 1 A schematic configuration of a robot system including the robot control device 10 of the present invention is shown. The robot control device 10 has a control unit 20 for controlling the robot 1 , and the control unit 20 has a CPU 22 , a ROM 24 connected to the CPU 22 , a RAM 26 , and a servo control circuit 28 . The control unit 20 also has a communication unit 30 for wirelessly communicating with a mobile operation unit 60 described later. The servo control circuit 28 may be provided on each axis of the robot 1, and supplies power to servo motors for each axis of the robot 1 (not shown) through the servo amplifier 32, respectively. The servo amplifier 32 is connected to the power source 2 for power through an electromagnetic contactor 34 installed in a line that supplies power to the servo amplifier 32 .

[0018] In addition, the control device 10 has an operation motor selection switch 36 for specifying the operation motor of the robot and a cycle start bu...

Abstract

A robot controller for avoiding an emergency stop of a robot due to shortage of the amount of charge of a secondary battery of a portable operating part during automatic operation of the robot. The robot controller includes a portable operating part having a secondary battery, a robot control part capable of communicating with the portable operating part and having a means for bringing the robot to an emergency stop when communication between the robot control part and the portable operating part is interrupted, a charging circuit for charging the secondary battery, and a cable for electrically connecting the charging circuit to the control part during automatic operation of the robot.

Description

technical field [0001] The present invention relates to a robot control device, in particular to a robot control device that wirelessly communicates with a mobile operation unit having an emergency stop button and a built-in secondary battery. Background technique [0002] The main application of the mobile operation unit is the teaching of the robot. When performing teaching, the operator often enters the safety fence surrounding the robot with the mobile operation unit in his hand, and performs teaching close to the robot. Therefore, in order to ensure the safety of the operator, an emergency stop button for urgently stopping the robot in an emergency is provided in the mobile operation unit. When the emergency stop button is pressed, the robot control device cuts off the power supply to the robot drive motor to immediately stop the robot. [0003] The mobile operating unit is generally connected to the control unit of the stationary robot controller via electrical cable...
