Principle

Tuning refers to a scan system’s dynamics configuration. It’s a fine adjustment of the

digital servo control that determines the scan system’s dynamic reactions while driven with a scan pattern.

Digital systems with iDRIVE technology – such as the intelliSCAN – can store up to three tunings in memory. Switching between those tunings is possible even during marking.

Always the ideal tuning

Special tunings can optimize scan systems to meet diverse requirements, such as for

vectors, jumps or micro-machining.

Application-specific tunings bring increased speed and positioning accuracy. The digitally implemented output stages reduce heat generation, leading to improved temperature stability.

What kinds of tunings are available?

Most tunings are characterized by tracking error and maximum speed.

Low tracking error facilitates spatiallysmall/intricate marking, but accompanied by limited maximum speed. In contrast, elevating speed will also increase tracking error.

Jump tuning is a special case where jump times are minimized for long jumps, resulting in complete elimination of constant tracking error. Jump tuning is particularly well-suited for drilling applications.

Scanlab Collimation Module

fiber connection for scan heads

Collimation Module

Fiber optic connection for scanning heads

The Collimation Module allows direct connection of fiber-coupled lasers to the scanning head. Typical apertures are 30 mm.

The module provides a robust mechanical coupling and optically collimates the laser radiation to match the aperture of the scanning head.

The optics used are suitable for multi-kW laser powers and can accommodate a wide range of beam qualities.

Unique features of the collimation modules

Ruggedized housing (water-cooled entrance aperture; stainless steel)

Manually adjustable collimating optics, including scale ring

Available with or without camera port (90°/180° models)

Pyrometer, vision and OCT connectable in 90° configuration

Additional beam splitter and camera adapter with C connector available as add-ons (for 90° configuration)

Flexible mounting options

Replaceable protection window in front of collimating optics

Good transmission to red-guided lasers

Optics for laser powers of several kilowatts

Typical Applications:

•  Welding, micro-welding

•  Cutting

•  Rapid prototyping, additive manufacturing

Typical Industries:

•  Automotive

•  Mechanical engineering and metalworking

Layout and Principle of Operation

The solidly designed Collimation Module includes an adapter for mounting the www.abb-drive.com module and scan system to a machine.

Installation is possible from four sides, providing a high level of integration flexibility.

Various fiber adapters are offered for laser coupling. The water-cooled, stainless-steel beam entrance aperture is corrosion-free even when using DI water.

A scale ring facilitates manual adjustment of the movable collimation optic.

This allows precisely setting the focus position to the scan system’s nominal working distance, as well as compensating for tolerances.

Housing

The Collimation Module‘s robust housing is dust and splash proof – particularly at the junction to the scan head.

A replaceable protective window in front of the collimation optic additionally protects the lens unit from dust infiltration when changing fibers.

This guarantees a long service life in industrial environments.

Optional Camera Port

The Collimation Module can be optionally equipped with a camera adapter for process control or workpiece position detection.

The light arriving from the workpiece is coupled out of the laser beam path by an integrated beam splitter and directed to an observation port.

The laser light itself, however, is nearly fully reflected by the beam splitter to establish a 90° angle between fiber-in and beam-out.

Scanlab Camera Adapters

Camera Adapters

The camera adapter allows process observation of the working plane of the galvanometer scanning head by means of a camera. This makes it suitable for process control during laser processing or for inspection of workpiece position and orientation.

Its mechanical interface can be mounted directly between the scanning head and the laser flange. Four camera placement positions are available for setting up the objective unit, ensuring easy integration into existing or new systems.

In order to observe the working plane, the light from there is decoupled in the camera adapter via a beam splitter and imaged onto the sensor via the camera objective. In contrast, laser radiation is transmitted almost unimpeded on its way to the scanning system.

vision for scan heads

The camera adapter enables camera-based observation of a galvanometer scan head’s working field. Typical applications include process monitoring or determination of a workpiece’s orientation during laser processing.

The camera adapter ensures easy integration into new as well as existing systems. The adapter’s mechanical interfaces enable straight forward mounting between the scan head and laser flange. The system allows 4 alternative orientations of the objective with camera.

To facilitate monitoring of work surfaces, light arriving from the workpiece is decoupled via the adapter’s beam splitter and directed through the camera’s objective onto its imaging chip. The laser beam on the other hand passes practically unattenuated through the beam splitter to the scan system. Optical configurations are available for various wavelengths. Customers can freely select a camera suitable for their requirements and attach it via a C-mount.

The camera adapter is specifically designed for maximum observation field size and its integrated iris diaphragm can be adjusted for optimal imaging quality. In addition,color or interference filters can be installed.

Installation

The camera adapter is mounted between the scan head’s beam entrance and the laser flange (see drawing). The bore holes at the camera adapter’s beam entrance and exit side are compatible with the mounting holes of the scan heads from SCANLAB.

The beam splitter housing can be adjusted so that the camera and objective unit are oriented either up, down or sideways (see drawing).

Principle of Operation

The camera adapter enables camera-based observation of a www.abb-drive.com scan head’s working field.

Therefore, a dichroitic beam splitter inside the beam splitter housing decouples light reflected from the illuminated workpiece and arriving the scan head’s beam entrancevia the scan objective and the scan mirrors.

The light is decoupled from the beam path and then directed to the camera. The laserbam on the other hand passes through the beam splitter practically unattenuated.

The decoupled light is directed through the camera objective onto the active imaging

surface of the camera (e.g. CCD chip Threaded in the beam splitter housing, the objective unit contains the camera objective, an iris diaphragm and provisions at the

beam entrance side for mounting a color filter. Camera image sharpness is achieved by manually adjusting the objective unit’s focus ring.

Customers can select an illumination wavelength compatible with the optical specifications of the beam splitter, scan mirrors and other system optics. Observation Field and Resolution The size of the observation field depends on the focal lengths of the scan objective and camera objective and on the camera chip’s size. A scan objective focal length of 163 mm typically produces a camera image field size of approx. 7.5 mm x 10 mm and a maximum optical resolution of around 10 µm (see table). This can be further increased by a 2-fold or 4-fold camera attachment, depending on the pixel resolution of the camera.
