Complete safeguarding of the production line
To be able to start all robot programmes on a production line from a single point, work objects and tools need to be measured as accurately as possible.
WIEST advantages
Customer benefits
The customer has the possibility to calculate the paths of his robots as far as it is possible. The prerequisite for this is the precise measurement of work pieces and tools with LaserLAB.
In addition, the entire production line is protected against downtime by re-teaching. If the line is moved later, not a single robot has to be reteached.
Integration on the second line without reteaching
Increase availability
Prevention of downtime
Shortening the commissioning
Case
Cell description
The customer is setting up an engine assembly line for a car manufacturer. A total of 26 high-precision ABB IRB 4400 and IRB 6640 robots are used, distributed over 15 stations and performing different tasks. These range from handling tasks to the application of adhesives or sealants, assembly and leak testing.
Task
The end customer wants the robot programmes to contain as few points as possible. Ideally, programmes should have a single starting point from which all other points are calculated. To enable this calculation, the work objects and tools must be defined as accurately as possible.
In addition, the plant must be protected against possible production stoppages.
Implementation
Using Wiest technology, the hardware of each station on the production line is digitally stored. This makes it possible to immediately restore the reference between the hardware and the robot programmes in the event of a crash or after replacing parts on the robot or tool.

Spot welding in body-in-white
A large car manufacturer operates several welding lines for car bodies. Kuka KR125 robots and Comau H4 with spot-welding guns are used.
The special feature of the production line is that a large number of different models are produced on the same lines, and new models need to be introduced with as little interruption to the running line as possible.
To make matters worse, re-teaching had to be done for all models. However, these were not available at the time of the work. The model may not have appeared until the next shift. If you forgot to stop the line and adjust the robot programmes, the crash happened again.
In addition, the task was to ensure that the Comau robots could be exchanged for new ones. There is no repeatable and reproducible mastering procedure for this type of robot.
