FFTmetrology CheckThrough Material defect detection with our transmitted light system
The transmitted light system is used for precise image processing to detect the smallest material defects such as cracks, the finest perforations and material tapering. The concept is based on stable and reproducible inspection conditions.
During the inspection, the component to be inspected is held flat and aligned as precisely as possible to ensure consistently high inspection quality. Illumination is provided by a homogeneous surface light from below, allowing even the smallest irregularities in the material to be visualised.
The entire test takes place inside a light tunnel. This controlled environment minimises external interferences such as extraneous light and ensures constant recording conditions. One or two commercially available industrial cameras are used to take the images, allowing perforations to be recognised quickly and reliably.
The system has already been extensively tested under laboratory conditions and a corresponding test setup is available. Wide-area lighting and a flexibly configurable enclosure for the test centre ensure outstanding stability and enable adaptation to different requirements.
FFTmetrology CheckThrough Process sequence of the transmitted light system
1. infiltration and measurement
The test specimen is transported to the transmitted light test via an automatic conveyor line. The test specimen is placed in the transmitted light unit by means of an automatic drawer. The transmitted light illumination is activated and the image is captured.
2. quality visualisation
Perforations and cracks are displayed on the screen. Even the smallest defect is clearly displayed in colour.
3. link with PLC
The results (IO, NiO) are sent to the PLC and stored in a database.
4. quality report
The software can be used to analyse the recorded results using various statistical methods.

FFTtesting eFlexMobile
Mobile test unit
With the FFTtesting eFlexMobile, modules or battery packs can be tested directly on the production line. The system enables a variety of electrical and functional tests (e.g. high voltage, insulation, load) and impresses with its modular design and high measurement accuracy.
FFTmetrology CheckThrough
Transmitted light testing
A transmitted light inspection is used to check whether components and features are correctly present and correctly assembled in order to detect faults at an early stage and prevent damage. The system uses 2D and 2.5D sensor technology to ensure a reliable quality inspection.
FFTmetrology ShapeScan
Quality control through optical 3D detection
Fast and precise recording of geometries and surfaces using laser scanners to control quality and processes. Examples include BeadControl and HemQC.
FFTmetrology Sensors
Image processing sensors
Our triangulation sensors and our double-head sensor measure gap and transition. Our surface sensor is used to measure round holes and rectangular holes. Our linear sensor is a stable and simple solution for distance measurement. Everything is connected with our hub.

FFTmetrology RGS
Robot Guiding System
The FFTmetrology RGS system is used to guide the robot to a calculated ideal position rather than to a teached position. For this purpose, 2D or 2.5D images are first captured and calculated.
FFTmetrology iPS
intelligent positioning system
It is determined the deviations of the vehicle bodies in just one station. The result can then be used for optimization in the following stations. The condition is that the body positioning in each station is the same and stable.
FFTmetrology BeadControl
Intelligent Adhesive layering control
The FFTmetrology Bead Control scans the adhesive bead and precisely measures its position, width and height. The measurement takes place while the adhesive is being applied, thus avoiding a loss of cycle time.
FFTmetrology VisionCheckup
Completeness check system
This system can be used to reliably check the placement of add-on elements and features, e.g. welding studs, holes, embossing, etc., so that missing or incorrectly placed parts are recognised immediately. It can be designed for 2D and 2.5D.
FFTmetrology Gap & Flush
Measurement of gap and flush values
FFTmetrology Gap & Flush is an automatic robot-based solution for stable measurement of gap and flush values.
For this application, the FFT VG DH (laser triangulation using a dual-head sensor) is ideal.
FFTmetrology HemQC
3D detection of the seam quality
FFTmetrology HemQC inspects the quality of the folded edge during the roll folding process. This is a scanning procedure in which the width and height of the fold or the excess adhesive is measured.
