Problems solved by technology
[0003] The magnetic force generated by the electromagnetic coil in the existing brake is controlled by a fixed duty ratio signal. When the robot is under heavy load and accelerates, the power supply voltage is pulled down. At this time, the PWM waveform of the fixed duty ratio signal makes the brake The available friction is reduced, with the result that there is a risk that the brake will not have enough friction to hold

The control device comprises a signal input interface, a power supply input interface, a processor, an acquisition module, a first energystorage module, a second energy storage module, a power supply output interface, a follow current module and a first filtering module. The processor is electrically connected with the power input interface and the signal input interface. one input end of the power supply output interface is connected with the power supply input interface through the acquisition module, the other input end of thepower supply output interface is connected with the processor through the first energy storage module, and the second energy storage module is electrically connected with the two output ends of the power supply output interface. Two ends of the follow current module are electrically connected with the acquisition module and the processor respectively, and the first filtering module is electricallyconnected with the processor and is grounded. The working stability of the band-type brake can be improved. In addition, the invention further discloses a band-type brake.
Description
technical field [0001] The invention relates to the technical field of brakes, in particular to a brake and a control device thereof. Background technique [0002] The brakes in existing robots are divided into striker-type brakes and electromagnetic brakes, wherein both the striker-type brakes and electromagnetic brakes are locked by a spring mechanism in a power-off state to close the brakes, and in the case of power-on, they are locked by a spring mechanism. The magnetic force generated by the electromagnetic coil pushes the spring mechanism to move to open the brake, and the electromagnetic coil and the motor are energized and stopped synchronously. [0003] The magnetic force generated by the electromagnetic coil in the existing brake is controlled by a fixed duty ratio signal. When the robot is under heavy load and accelerates, the power supply voltage is pulled down. At this time, the PWM waveform of the fixed duty ratio signal makes the brake The available friction ...
