Industrial robot motor band-type brake controller with safety monitoring device

Abstract

The invention provides an industrial robot motor band-type brake controller with a safety monitoring device. The controller comprises a system control module used for automatic system control, a manual control module used for manually releasing a band-type brake, a coil energy releasing module used for shortening the band-type brake reaction time and a safety detection module used for monitoring whether buttons have faults. The system control module is arranged in a control cabinet of a robot, the manual control module is arranged on the robot, and the system control module, the manual control module and the coil energy releasing module are connected with band-type brake coil interfaces of a motor of the robot correspondingly; the safety monitoring module is connected with the manual control module. According to the controller, a safety detecting device for manually releasing band-type brake control is added, so that industrial accidents caused by mistaken releasing of the band-type brake are avoided.

Description

technical field [0001] The invention relates to the field of mechanical controllers, in particular to an industrial robot motor brake controller with a safety monitoring device. Background technique [0002] In the industrial robot control system, the servo motors used in the joints of the robot body are usually motors with brakes, and the control of the opening and locking of the brake coils of the motors is usually given by the robot control cabinet; when the robot control cabinet When a fault occurs and the brake release signal cannot be given, the staff needs to manually open the motor brake of the industrial robot body to adjust the joints to a suitable position for maintenance. This part of the control function is usually controlled by the brake control device. button to achieve. The button for manual control of the brake may be aging and invalid due to long-term use. There are two possibilities for button failure: one failure is that the actual contact does not act ...

The button for manual control of the brake may be aging and invalid due to long-term use

There are two possibilities for button failure: one failure is that the actual contact does not act when the button is pressed, in this case the robot brake will not open, and there will be no danger; the other failure is that the button contact is stuck and will not bounce If the button contact used for manual control of the brake fails, when the power of the manual control brake is turned on, the motor brake of the industrial robot is always open, and there may be a danger of turning around, which may cause injury to the operator.
