Abstract

The invention relates to a galvanometer control detection device, and relates to the technical field of motor control detection. The galvanometer control detection device comprises a regulator, an amplifier, a swing type motor, a driving current detection module and a temperature detection module. The output end of the regulator is connected with the first input end of the amplifier, the output end of the amplifier is connected with the input end of the swing type motor, the first output end of the swing type motor is connected with the input end of the temperature detection module, and the output end of the temperature detection module is connected with the first input end of the regulator; the input end of the driving current detection module is connected with the output end of the amplifier, and the output end of the driving current detection module is connected with the second input end of the regulator. The galvanometer control detection device is used for solving the problem that only feedback protection is carried out on the swing type motor at present, and protection for a drive control circuit of the swing type motor is lacked.

Description

technical field [0001] The present application relates to the technical field of motor control detection, in particular to a vibrating mirror control detection device. Background technique [0002] Galvanometer applications include laser marking, 3D printing, laser drilling, laser welding, laser cutting, laser cleaning, laser medical, biomedical and ophthalmic imaging. The galvanometer is the core component of the laser system. The galvanometer can deflect and reflect the laser. The rotation of the oscillating motor makes the mirror deflect to reflect the laser deflection angle. The oscillating motor is controlled by the circuit and detected for movement and self-inspection. [0003] The galvanometer control system includes a closed-loop feedback control system, a detection system, a power amplification system, a compensation system, a signal conditioning system and an angle sensor. The existing galvanometer control system has weak self-inspection ability, and the current, ...
