Surround view cameras which are installed in the front and rear of our cars as well as in the exterior mirrors are the first step towards autonomous driving. An increase in the number of automobiles produced as well as upcoming guidelines regarding energy efficiency and safety will result in a multiplied demand of control units and sensors. With our fully automatic assembly and testing machines for surround view cameras we are optimally equipped for the future demands of the market.
Today all kinds of pressure sensors are used in most of the systems in our cars, e.g. in the intake system or the brake system. Our calibration systems subject these sensors to various quality tests both under room temperature as well as after heating them under high temperature before calibrating them. Calibration is done in several stations where the components are electrically and pneumatically contacted and where the sensors are subjected to a controlled pressure.
This process is monitored by complex measuring systems. Once the calibration has been successfully completed, a marking laser applies a DMC to the component and it will be discharged as good part.
Ceramic sensor elements are integrated in lambda probes used for vehicles. Our conditioning and testing machines can be used to subject the workpieces to various testing processes during which electric function variables are measured at the sensor element. Voltages in a range of mV - µA are measured and evaluated during various multiple tests carried out one after the other. Additional tests are carried out under preset atmospheric conditions at operating temperature. After discharging from the testing stations the sensor elements pass through an electrolyte impregnation unit as well as a conveyor belt furnace. The lines feature a modular design thus allowing a step-by-step capacity extension.
For many automobile manufacturers the future lies with electric drive systems. In the years to come the internal combustion engine will nevertheless play an important role, even though it will be combined with an electric motor in form of a hybrid powertrain. This is why automobile manufacturers will continue to invest in production lines for internal combustion engines. The lambda probe is one of the key components of the gas engine. For many years our customers have been relying on our assembly and testing machines with pre- and final assembly for lambda probes. Changeover is carried out automatically thanks to a connection of the machine to the master computer. The individual components are fed to the machine and sorted automatically; they are then assembled in pressing and joining stations with process monitoring. Consumption data measuring and recording, semi-automatic measuring and testing routines as well as a fully automatic final inspection are additional highlights of our machines.
