Abstract
The utility model discloses a laser marking device which comprises a controlling part, an optical pump, a laser, a driving part, a scanning galvanometer and a workbench. The laser marking device is characterized by further comprising an optical sensor and a comparing part. The controlling part outputs an electronic signal to the optical pump and outputs a signal 1 to the comparing part, the optical pump sends out an optical signal to the laser, and the laser emits a laser beam. The head of the laser or the workbench is provided with the optical sensor. The optical sensor transmits a signal 2 to the comparing part after detecting the laser beam. The comparing part transmits a signal 3 back to the controlling part after the comparing part works out the delay time according to the signal 1 and the signal 2. The controlling part controls the driving part to drive the scanning galvanometer according to the delay time. The laser marking device has the advantages of being simple in structure and capable of marking continuously, and the phenomenon of incomplete marking is avoided.
Description
Technical field
