Bearing Laser Printer Machine&aker
|Lamp-pumping (YAG) laser marker takes Kr Lamp as pumping source, radiating Nd: YAG crystal to produce a great deal of contra-rotating particle, which release then 1,064 mm great impulse laser through the modulation of acoustooptical switch; And, the laser, running across the F-Q lens, focuses on the workpiece' S surface and gets it oxidized and gasified instantly by dozens of Watt laser energy within few square microns; Thus, the laser burned mark is forever kept. |
1) Fast and accurate positioning with good designs
2) Special multi-layers and indexes setting makes fake grey scale possible to be marked.
3) Available multi-text flexible order consecutive marking gets large work pieces easily marked.
4) The effective 1:1 design presents drafting is marking.
5) The automatic random number-jumped design is helpful for monitoring logistics.
6) The strong 2 P cooling system guarantees 24h continuous processing available.
1. Computer: Lenovo A6T mainboard,128M memory,20Gharddisk
2. Monitor: SAMSUNG 15"color monitor
3. Laser power supply: PWM with Germany IGBT
The laser power supply utilizes PWM control and single closed feedback loop; And the output current goes through IGPT produced by EUPEC Gmbh. The high-voltage ignition circuit could transmit thousands of volt. Upon capacitance storage and transformer stepup. There're three protection items for the laser power source:
1) overload:25A,32A two levels
2) overheat: Power off upon 800C
3) underpressure and overheat: LED by the pum or trough
And cooling system which fail to work
4. Laser bar: Dia 4*120mm, USCO.
5. Q system: Less than 50KHz, US NOES CO.
Q switch modulates the consecutive beam into high frequency impulse laser in the cavity(200-50KHZ). As the peak value of pulse laser is much higher than it of average laser radiation, it improves marking efficiency greatly.
Energy to laser. After being absorbed by media and producing laser, the rest energy changes into thermal energy flooding the small pump cavity, which needs to be discharged in time, or blows down the Kr Lamp, crystal, glass tube, cavity, and so on. The cooling system is composed of tank, pump, refrigerator, pressure and temp. Transducer, control system and etc.
