Leading Manufacturer in the Coding & Marking Industry since 2011.
1. The role of the thermal lens of the laser marking machine: it is mainly composed of a driving board, a servo motor and an X-Y optical mirror. When the reflectivity of the mirror is low, there are impurities in the medium and the surface is contaminated. When the laser beam is irradiated, the mirror is thermally deformed. Finally, after passing through the mirror, the spot becomes smaller and the depth becomes shorter. 2. Electrode part of laser marking machine: The laser of laser marking machine generally adopts cylindrical cold cathode, and the cathode material is laser. The field lens is mainly composed of a meniscus lens.
3. Ordinary mirror resonator cavity of laser marking machine: usually based on optical glass, the surface is coated with gold film. In the vicinity of 10.6um, the reflectivity of the gold-coated mirror is greater than 98%. The output mirror of the resonator is usually made of the infrared material germanium and emits radiation at 10.6 microns.
4. Optical delay: the delay time of the laser when the laser marking machine starts marking. The 'match head' at the beginning of the marker can be eliminated by setting the appropriate On Delay parameter, but if the On Delay parameter is set too large, the pen at the beginning will be lost. It can fire numerical and negative lasers to mark time ahead. 5. Lights out delay: The delay time to turn off the laser at the end of the mark. Setting the appropriate ignition delay parameters can eliminate the non-closing phenomenon at the completion of the mark. However, if the ignition delay is set too much, the 'match head' will appear at the end. Cannot be negative. #Laser Marking Machine# 6. Point judgment: press and hold the Enter key, do not place continuous marks. Observe the brightness of the laser beam on the bench and listen for the marking sound as the main beam rises and falls. Spot-flat spot is the strongest and loudest spot. After focusing, turn off the start switch and fix the high beams.There are many issues that affect expiry date printing machine, which has led to the need of getting specialists trained in certain areas so as to handle all issues that may arise as well as cij printer products that can solve date coding machine problems.
