Abstract

The present invention relates to one kind of laser machine and the laser marking machine has one optical imaging system comprising graphic output mirror, focusing lens and marked workpiece and has adjustable marking area. The machine has one heat exchange system comprising refrigerating compressor and other part to ensure the long-term continuous and stable operation of the laser. It utilizes pulsed laser to mark product and performs accumulation count.

Description

A kind of pulsed CO 2 laser marking machine with figure output
The present invention relates to a kind of laser instrument, be specially adapted to the laser marking machine use occasion.
Improving electro-optical efficiency or the laser output energy and the long stable operation of laser instrument, is the problem that people extremely pay close attention to.Laser marking machine is more outstanding to above-mentioned requirements, and the product that is marked is generally all wished mark greatly and clearly, and online with production line, to product mark one by one.Chinese patent ZL921043120 discloses a kind of " laserresonator that is used for laser marking machine ", its structure is that the resonator outgoing mirror is made up of required literal, figure, make the laser beam of output have the feature of literal, figure, directly beat on product, promptly obtain required mark, the energy of its laser output that is the energy of figure also all are utilized.Adopt outer mask to compare with routine, the energy that obtains figure by mask is for effectively utilizing energy, and the masked energy that blocks is the energy of loss, and the ratio of blocking is big more, loses also manyly more, and eye diagram is exported and improved laser and export energy utilization ratio.But the mark of every kind of product all has the requirement of its specific literal, pattern and area size, and the design of optical resonator and the coupling of parameter are brought many inconvenience.Even can't implement.
At the shortcoming that above-mentioned prior art exists, the purpose of this invention is to provide: the outgoing mirror of (1) optical resonator is the figure outgoing mirror, forms outer light path device by the condenser lens and the workpiece that is marked; (2) outgoing mirror of optical resonator is conventional outgoing mirror, is made of the CO 2 laser marking machine of outer light path device external graphics mask, condenser lens and the workpiece that is marked.They make the mark area adjustable within the specific limits, need not the round-the-clock continous-stable operation of cooling water and synchronous mark of production line and stored counts.
The present invention takes following technical measures:
Measure one, it is made up of electrode 2, optical resonator, heat-exchange system, housing 3, inflating and exhausting system 10, power supply 8, outer light path device and Light Electronic Control System 9 etc., in laser instrument, fill with mists such as carbon dioxide, nitrogen, helium to realize the operate as normal of laser instrument, the outgoing mirror of described optical resonator is the figure outgoing mirror, it is a combined lens, constituted by figure mirror 4 and conventional outgoing mirror 5, and formed optical resonator with total reflective mirror 1.And the figure outgoing mirror is formed optical imaging system with the condenser lens 6 and the workpiece 7 that is marked in the outer light path device.The refrigeration heat-exchange system that described heat-exchange system is made up of hermetically sealed compressor, the import of refrigeration compressor 11 is communicated with the port of export of heat exchanger 13, the outlet of compressor 11 is communicated with the entrance point of heat exchanger 13, and blower fan 12 places interchanger 13 1 sides.
Measure two, it is made up of electrode 2, optical resonator, heat-exchange system, housing 3, inflating and exhausting system 10, power supply 8, outer light path device and Light Electronic Control System 9 etc., in laser instrument, fill with mists such as carbon dioxide, nitrogen, helium to realize the operate as normal of laser instrument, the outgoing mirror of described optical resonator is conventional outgoing mirror 14, constitutes optical resonator by it and total reflective mirror 1.Form optical imaging system in this device by external graphics mask 15, condenser lens 6 and the workpiece 7 that is marked.The refrigeration heat-exchange system that described heat-exchange system is made up of hermetically sealed compressor, the import of hermetically sealed compressor 11 is communicated with the port of export of heat exchanger 13, the outlet of compressor 11 is communicated with the entrance point of heat exchanger 13, and blower fan 12 places interchanger 13 1 sides.
The area that the invention has the advantages that the mark machine is adjustable within the specific limits, and can reduce the input power use of laser instrument within the specific limits; Need not cooling water can move by round-the-clock continous-stable; Can with the synchronous mark of product and the stored counts of advancing on the production line; When resonator designed, the selection of parameter matching was more convenient.
