Abstract
A marking device for the creation of an optical mark onto an object has a laser connected to a power supply unit to create a laser beam and a speed acquisition device for determining a positioning speed at which the laser beam follows a repetitive pattern upon the object. The power supply unit has a controlling unit connected to the speed acquisition device which controls the intensity of the laser beam based upon the positioning speed. When the positioning speed decreases the lower predetermined value, the laser beam power is reduced and, if the positioning speed decreases below a minimum positioning speed, the laser beam is switched off.
Claims13
A marking device for the creation of an optical mark onto an object, wherein the device is comprised of:
- a) a laser connected to a power supply unit to create a laser beam;
- b) a positioning device for positioning the laser beam upon the object;
- c) a position control device for controlling the positioning device to project the laser beam in a repeating pattern upon the object at a scanning frequency;
- d) a speed acquisition device for determining a positioning speed at which the laser beam follows the repeating pattern;
- and
- e) a controlling unit for the power supply unit, wherein the controlling unit is connected to the speed acquisition device and wherein the controlling unit controls the intensity of the laser beam based upon the positioning speed.
