 CO2 laser marking machine is applicable to materials and industrial applications CO2 laser printer standard machine-ray machine can engrave a variety of non-metallic materials. Used in garment accessories, pharmaceutical packaging, building ceramics, beverage packaging, fabric cutting, rubber, shell plate, craft gifts, electronic components, leather and other industries. The typical application cases, such as laser flying marking of the box body, paper, metal detonator shell code printing. 
 Laser marking machine principles 
 The laser marking is marked with a permanent marker in a variety of material surface with a laser beam. Marking effect of the evaporation of surface material to reveal the deep substance, or by light lead to the chemical and physical changes of the surface material and "carved" out of the traces, or is required to etch the pattern of light burned part of the material, showing the text. Recognized the principle of two types: thermal processing has a high energy density laser beam (which is a concentrated energy flow), the irradiation on the material surface, the surface absorption of laser energy, generate heat in the irradiated region excitation process, so that the material surface (or coating) temperature rise, resulting in abnormal, melting, ablation, evaporation phenomenon. "Cold" high load energy (UV) photons can interrupt the material (in particular, the chemical bonds within the organic material) or the surrounding medium, to make a material non-thermal process destroys. The cold laser marking processing has special significance because it is not thermal ablation, but does not produce side effects of thermal damage, interrupting the chemical bonds the cold peel, and thus the inner layer of the surface to be machined and the nearby area produce heat or thermal deformation effects. For example, the electronics industry using the excimer laser deposition of chemical substances on the base material film, out of the narrow slot in the semiconductor substrate. 
 CO2 laser marking machine common problems and solutions 
 The laser tube bright voltmeter instructions ① light unusual light guide joint fever is common in the joints loose and the laser tube of the light guide is not loaded is. Inspection methods: optical correction. Exclusion measures: the replacement or adjustment of the light guide festivals, correction optical path. ② laser power drop is common in the laser tube aging. Check: check with a multimeter voltage profile regulator, high-pressure table to check the laser tube operating voltage. Processing: the replacement of aging of the laser tube and replaces the defective component. The laser tube is not lit ① the voltmeter indicate common in the supply line open. And foot pedal or manual switch is bad. Check: measured with a multimeter. Treatment: repair or replacement. ② voltmeter indicates the common fuse off, or circuit open. Check with a multimeter measurements. Treatment: Replace the fuse or circuit connected. ③ Power indicator does not light the common fuse, the line is poor contact, poor indicator line or indicator has been bad. Check: Check the fuse, check the power line, check the indicator circuit. Processing: fuse replacement, repair wires and replace the light. ④ continuous burning fuse is common in the machine short-circuit, and the machine have a serious dirt. Check: step by step to check the line, mostly for high-pressure part of the short circuit. : Repair the short circuit, remove the dirt. The ⑤ machine discharge sound common arc light machine dust, too much water or air humidity and corrosive gases. Check: in the dark to observe the discharge point. Treatment: remove dust, water and other things, the replacement of the working environment. ⑥ laser output instability seen in poor contact between the CO2 laser marking machine, machine, there was a slight intermittent short-circuit point. Check: step by step to check the line. : Replacement wires, re-welding of a thread, and cleaning. 
 Operating CO2 laser marking machine Note 
 (1) CO2 laser marking machine is found to use the adjustment due to wet or there are other reasons for discharge should be immediately shut down for overhaul. (2) at low currents, the CO2 laser marking machine can continuously work for four hours, when the large current may, at their discretion, reduce the use of time. (3) chassis ground wire power cord for single-phase three-wire. (4) articulated arm of the light guide when not placed in the oven, to prevent the lens moldy. (5) maintenance of the first cut off the power and high voltage discharge to ensure safety.
