advintec 6D laser measurement
Cost savings with BizLink unracking solutions
The challenge:
In modern production plants it is often necessary to extract parts (body side panels, roofs, hoods and similar parts) that are then delivered in bins for further processing in a fully automated fashion. To this end, industrial robots are mostly used. If the part is not exactly located where expected, the robot cannot continue its operating cycle.
The solution:
- Guidance of the robot via an electronic part-calibration system
- 6D calibration of the part position (translation and rotation) by means of laser or infrared sensors integrated within the gripper – direct connection with robot controller via field bus
- Automated adjustment of pick position – online
Your benefit:
- Cost saving in comparison to conventional mechanical systems
- Easy maintenance and ease of use
- Robot guidance independent of lighting conditions or part variations
- Minimization of training costs for users and maintenance staff
- Compact, light, robust and integrated directly into the gripper, the system can be retrofitted to the production line without time-consuming modifications
Correction takes place directly and automatically in the ongoing production process. During setup the correct part position is learned automatically.
Easy to understand – short instruction time and ease of use.

Cost savings with BizLink gripper measurement solutions
Task:
To measure grippers or gripped parts for precision handling, e. g. for power-train applications, such as engine and transmission parts.
Solution:
- 6D laser measurement of grippers / gripped parts using stationary sensors.
- Changes in the gripper / part position are detected early and corrected online. This avoids collisions and optimises precision positioning.
Your benefit:
- High precision 6D laser measurement
– No calibration tools or reference parts required (high cost savings) - Robot program corrections take place directly and automatically within the ongoing production process
– No failures caused by positioning factors
– Avoids collisions - Eliminates manual program corrections
- Simple to integrate and use
- Simple commissioning via supplied robot program
- High tolerance to ambient light
- Measurement time < 20 s (dependent on configuration and application)
- Cost savings compared to conventional mechanical systems
- Protection class IP67
- Suitable for harsh environments
- Use of different laser sensors – appropriate to application
