Know-how Universal hemming inspection for maximum data acquisition

A scanning system for optical 3D acquisition is used to ensure the highest quality standards in roll hemming processes. A laser light section sensor is used to measure hemming geometries and adhesive seals precisely and without contact. The system reliably records the position, height, width and any adhesive leakage.

In addition to geometric analysis, this fold control also enables the detection of critical quality characteristics such as gaps in the seal, insufficient adhesive volume or incorrectly positioned sealing adhesive. Precise 3D capture enables continuous inline monitoring, which detects errors at an early stage and thus ensures stable, reproducible production quality.

The measurement data from the hemming inspection forms the basis for efficient process control and documented quality assurance – tailored to different types of roll hemming and adhesive technologies.

Installation of the FFTmetrology HemQC Equipment

  • Can be used for any shape

Stable quality control

  • Detection of gaps, insufficient volume or incorrect position of the sealing adhesive on the components

Quality documentation

  • Quality data can be made available for further processing
  • Use for further car bodies

Installation of the FFTmetrology HemQC Simple implementation in 4 steps

Roller fold production

First, the fold is produced in three passes (folding speed 100 mm/sec.). The roller hemming measurement then takes place in the third pass.

Measuring rate and quality visualization

Recording of one image per millimeter. The fold quality is then visualized using red, yellow and green markings.

Link with PLC

These visualized results are sent to the software under the following identifiers and saved as a database:

  • IO - OK
  • NiO - not OK
  • Incorrect measurement

 

Final quality report

The software can be used to evaluate the recorded measurements using various statistical methods.

Professional calibration of servo-pneumatic and servo-motorised robot welding guns, including determination of the deflection of the electrode arm geometry using 3D measuring systems and logging.

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.
