Laser direction guiding assembly and laser processing device having the same

A laser processing device configured to process a to-be-processed object through laser;

• the laser processing device comprising:
• a laser emitter emitting a laser beam;
• a laser direction guiding assembly receiving the laser beam from the laser emitter;
• the laser direction guiding assembly controlled by the laser processing device and configured to adjust a route direction of the laser beam emitted into the laser direction guiding assembly to adjust a coordinate location, in a first direction and in a second direction, of the laser beam on the to-be-processed object when the laser beam is emitted to the to-be-processed object, the first direction and the second direction being perpendicular to each other;
• the laser direction guiding assembly comprising
• an offsetting mirror set comprising
• an offsetting reflection mirror;
• and
• an offsetting-mirror-pivoting motor connected to the offsetting reflection mirror and controlled to drive the offsetting reflection mirror to pivot axially;
• a first-axis mirror set comprising
• a first-axis reflection mirror;
• and
• a first-axis-mirror-pivoting motor connected to the first-axis reflection mirror and controlled to drive the offsetting reflection mirror to pivot axially;
• a pivoting axis of the offsetting reflection mirror and a pivoting axis of the first-axis reflection mirror being parallel to each other;
• a second-axis mirror set comprising
• a second-axis reflection mirror;
• and
• a second-axis-mirror-pivoting motor connected to the second-axis reflection mirror and controlled to drive the second-axis reflection mirror to pivot axially;
• the pivoting axis of the first-axis reflection mirror and a pivoting axis of the second-axis reflection mirror being non-parallel;
• a concentrating lens set disposed adjacent to the laser direction guiding assembly and receiving the laser beam reflected by the laser direction guiding assembly to make the laser beam focus;
• and
• a moving platform disposed under the concentrating lens set and controlled to move along the first direction and the second direction;
• wherein the to-be-processed object is loaded on the moving platform;
• the laser emitter emits the laser beam to the laser direction guiding assembly;
• the laser beam is emitted to the offsetting reflection mirror to be reflected along an offsetting angle to the first-axis reflection mirror, then the laser beam is reflected by the first-axis reflection mirror to be deflected along a first angle, which is different from the offsetting angle, to adjust a coordinate along the first direction of the laser beam when the laser beam is emitted to the to-be-processed object;
• the laser beam is reflected to the second-axis reflection mirror to adjust a coordinate along the second direction of the laser beam when the laser beam is emitted to the to-be-processed object, and to be reflected to the concentrating lens set;
• the laser beam passes the concentrating lens set and is focused on the to-be-processed object on the moving platform.
