Laser / Scanning Control Software
Fiber Laser Systems’ laser / scanning control software offers a robust and flexible solution to make your laser marking project a success. The control software is a fully featured, professional Windows based software package for laser marking, coding, perforating, and many other laser scanning applications. When combined with the 2 axis scan head and a laser, the laser processing possibilities are endless.
The software allows graphics job editing that enables you to assemble images, text, and barcodes and quickly arrange them into marking jobs. With a simple point and click, you can graphically edit marking objects, precisely control laser parameters, and build automation scripts within a single interface. You will be able to define and run jobs within a few minutes. This high performance, laser scanning control solution is designed specifically to run on Windows XP.
2 Axis Scan Head
The Fiber Laser Systems’ Scan Head offers higher performance in a small package. The Scan Head is the smallest and fastest 10 mm head in the industry. The scan head is designed to ease design-in and manufacturing issues by reducing the need for specialized tooling and highly skilled assemblers and features the following:
Packaged in a class IV enclosure, the scan head can operate in harsh industrial environments. The scan heads are run through a battery of tests and must pass an extensive burn-in process.
Scan Heads feature the fastest and most accurate galvanometers with exclusive ceramic rotor technology for superior performance. Scan heads also feature high quality ceramic ball bearings for long life operation. The laser scanning head operates on the basis of the following schematic:
The F-theta focusing lens then projects the laser beam to a focused spot on a flat plane that is the size of that lens’s scanning field. In this manner the computer servo controlled scan head dynamically vector projects the graphic image onto the work surface in that focal plane to mark or engrave the part placed in that field. The scanning mirrors are very light weight and low in inertia, and can move at very high speeds to laser mark parts at exceptional production rates. The computer control can turn the laser beam on and off, vary the power and pulse frequency, and perform the appropriate number of passes required to produce the highest quality mark, and all relative to the position of the scanner mirrors at any given time.
Work Station and Enclosure
The work station platform is 32” x 60” and provides adequate work platform room on either side of the CDRH Class I Operator Safety Enclosure for a container of unmarked parts on the right and a container to accept marked parts on the left. The safety enclosure is equipped with a protective safety flap that automatically actuates when the dial table is indexed to provide unencumbered operator access for loading and unloading parts. This feature will substantially increase the production throughput of the laser marking system. The laser scanning head is inside the safety enclosure and mounted to a horizontal motor driven mechanism to index the laser scanning head to pre-programmed positions as dictated by the parts marking program. Sequence of Operation
The sequence of operation for this fiber laser marking system is as follows:
1. Turn power switch on. 2. Download the marking file to be used by manual entry, or automatically by scanning a job ticket bar code with the optional bar code scanner. 3. Place the part in the proper position on the locating fixture of the dial table that is in the load position. 4. Activate and hold the palm buttons until the dial table indexes the unmarked part into the work enclosure and in position for marking (the marking will start automatically when the dial table finishes indexing). 5. While marking is taking place at station #1 of the index table, the operator unloads and reloads parts at station #2 of the dial index table which is now outside the work enclosure. 6. The operator activates the palm button again, and this process is repeated until all the parts in that lot have been marked. Load/UnLoad Station with Part on Small Rotary Table. This System is equipped with safety light curtains to inhibit indexing while the operators hands are in the loading area.
This is the marking station inside the work enclosure where the laser marking takes place. In this application the round part is rotated about the vertical axis and the laser beam is projected horizontally. The part is marked "On the Fly" around the periphery while it is being rotated by the servo drive.
