Abstract

The invention discloses an abnormality detection device and method for an electromagnetic brake, and relates to the technical field of electromechanical control. The abnormality detection device comprises a signal controller, an optical coupling input circuit, a switching control switch, a detection circuit, an optical coupling output circuit and a processor; the signal controller, the optical coupling input circuit, the switching control switch, an electromagnetic brake device, the detection circuit and the optical coupling output circuit are sequentially connected; the processor is connectedwith the signal controller and the optical coupling output circuit; the processor controls the signal controller to send a control signal; the optical coupling input circuit couples the control signal into the switching control circuit; the switching control circuit controls the electromagnetic brake device according to the control signal; the detection circuit detects the electromagnetic brake device and obtains a detection signal; the optical coupling output circuit couples the detection signal into the processor; and the processor judges whether the electromagnetic brake device is abnormalaccording to the control signal and the detection signal. According to the invention, whether a state of the electromagnetic brake is abnormal can be accurately judged according to the detection signal.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to an abnormal detection device and method for an electromagnetic brake. Background technique [0002] With the steady advancement of the "Made in China 2025" plan, industrial robots are being used on a large scale. Taking a six-joint industrial robot as an example, there is at least one joint that can perform work against gravity. When the motor in the joint does not work, or when the industrial robot is not powered, in order to ensure that the joint of the industrial robot does not sag, the motor with a brake is usually selected as the driving motor. In the industrial robot industry, the electromagnetic brake is generally used The motor of the gate is used as the driving motor of the industrial robot. [0003] However, in the prior art, only a control signal to open or close the electromagnetic brake of the motor can be issued, but it is impossible to determine...
