Task
In order to increase the safety of car drivers further, nowadays sensors are used in tyres to measure the tyre pressure. They serve different purposes; for instance, reduced wear and tear due to optimum tyre pressures is mentioned.
The tyre pressure sensor itself consists of both mechanical and electronic components. We inspect and check several requirements within the same process. First of all, we assist with the sensor assembly; to do so, we support the robot that is responsible for inserting the energy components. After the memory has been inserted, its exact position is transmitted to the laser procedure system for laser welding. A matrix code has been applied to the sensor board, which is read for identification and verification purposes and stored in a central database. The traceability of batches is guaranteed.
Customer Benefit
- The sensor board is correctly assembled.
- Flawless welding is guaranteed
- Quick type change thanks to flexible handling, robot and image processing.

For the solution, we rely on a flexible handling system, consisting of a robot and machine vision technology. Whilst the image processing unit ensures that the energy component in the blister pack is picked at the precise position, a further image processing station transmits the correct positions of the inserted memory elements in the sensor for laser welding. At the end of the production process, the assembled tyre pressure sensor is sealed. We check this seal to ensure it is complete.
