LASER MARKING SYSTEM
First Claim
Patent Images
1. A laser marking system for marking a part, comprising:
- a laser;
a marking chamber through which the light of said laser passes wherein at least a portion of at least one surface of a part to be marked forms one side of said marking chamber;
a sealing head which includes a vacuum chamber surrounding said marking chamber, said vacuum chamber adapted to form a vacuum seal with the part to be marked with said laser, wherein at least a portion of at least one surface of the part to be marked forms one side of said vacuum chamber;
a vacuum generation device adapted to provide a vacuum within said vacuum chamber when said surface of said part has formed said side of said vacuum chamber thereby sealing said vacuum chamber to said part;
a vacuum sensor associated with said vacuum chamber to measure the vacuum within said vacuum chamber;
a control mechanism, said control mechanism activating said vacuum generation device and confirming a desired level of vacuum via input from said vacuum sensor and thereupon activating said laser to mark said part.

15. A method of marking a part using a laser marking system, comprising the steps of:
-
providing a part;
sealingly engaging the part with an enclosure;
drawing a vacuum between the part and the enclosure; and
activating a laser to mark the part.

16. A laser marking system for marking a part, comprising:
-
a laser assembly configured to selectively mark a part;
a pressure regulating assembly;
an enclosure having an opening, wherein the laser assembly is configured to selectively mark a part through the enclosure; and
an opening seal surrounding the opening, wherein the opening seal is configured to sealingly engage the part and to form a chamber with said part, whereupon the pressure regulating assembly provides a pressure differential in said chamber before activating the laser assembly to mark the part
