Laser projectors were developed as optical systems. This allows working without templates in many production processes.
It is projected directly onto the work piece and displays how the material must be positioned or mounted.
Thus employees are optically guided through the production process.
In General, a laser projector is built from a point laser source, a collimator lens and a deflection unit
consisting of two galvanometer motors with mirrors.
Figure 1 shows schematic of the structure:
The galvanometer motors are high-precision components, which have a repeatability of 8 micro radians
- which corresponds to a difference of just 8mm at a distance of 1,000,000mm.
Either a modulated red diode laser with 635nm or a modulated green DPSS laser with 532nm is used.
Factory calibration guarantees the highest accuracy
The laser projector production process consists of more other mechanical parts. To compensate the tolerances of the projector,
each individual Z-LASER projector has to pass through the "factory calibration" on our high-precision calibration wall:
this calibration wall has a total area of 6,000 x 6,000mm with a grid spacing of 100 mm in X and Y direction.
. The projector is mounted vertically with a fixed distance of 3,576 mm to the wall.
During the calibration process, each grid point is passed individually and the set and coordinate is compared to each other.
The individual correction values are stored in a matrix. This calibration ensures a faultless result as long as the process, as long as
the process is not performed for a too long period of time and the temperature remains constant.
The calibration grid is the basis for the coordinate system of the projector:
X-axis to the right
Y-axis to the left
Z-axis towards the projector
