Automotive: test bench and production control

Eddy current sensors from Micro-Epsilon are considered as proven measuring instruments in the test bench of combustion engines. In towing mode as well as in the firing mode, the sensors detect different quantities which contribute to the…

The MultiAir cylinder procedure patented by FIAT / Schaeffler controls individual valves independently of the camshaft. An electro-hydraulic control system provides fully variable valve control.Therefore, the stroke and the opening/closing times…

When processing car brake discs, the correct brake disc must be chosen before each stage of production in order to assign them to the manufacturer's different models. Laser scanners are used to recognise and classify the brake discs. The…

In modern production lines, scanCONTROL laser scanners are used to reliably inspect the gap sizes of the car body quickly and consistently. Thanks to surface compensation, measurements are possible on a wide variety of body paintworks. …

In aluminum die casting, liquid aluminum is poured into molds under high pressure and at high speeds. The high pressure acts on the closed mold and pushes it apart, which is why splinters and burrs might occur during casting. In order to measure…

Before a car emerges from a bodyshell, it passes through numerous stations within the production, in which fully automatic processing steps are carried out. In order to enables the processing robots to recognize the exact position of the car…

High quality standards and the visual appearance of products are crucial factors in every industry sector. Visible parts presenting unwanted flaws suggest low quality. Particularly in the automotive industry, optical sensors are used which…

With the surfaceCONTROL2500 3D sensor from Micro-Epsilon, diffuse reflecting surfaces can be inspected on a non-contact basis using 3D data. This allows local surface deviations to be identified clearly and automatically. Finally, an objective…

As well as the visual requirements, instrumentation panels also have to fulfill functional and security requirements. Often the passenger airbag has a predetermined breaking line which is generated using a laser. This "weak point" ensures the…

During the road test, powerful laser profile scanners and miniaturized laser sensors record lowfrequency vibrations and the movement of components within an assembly space. They test, for example, how assemblies move while driving or how the…

With the capaNCDT DTV, Micro-Epsilon has developed a product range that is specifically used for non-contact detection of the Disc Thickness Variation. Thickness measurements of brake discs can be carried out in test benches, in road tests or in…

Fully or semi-automatic assembly of cockpit modules in the automotive industry requires the gripper tool to precisely position the assembly parts. As the laser scanners take over the measurement and positioning tasks, each cockpit module is…

The car body must stop at exactly the intended position. This is the only way to ensure smooth installation via the robot, which must guide the cockpit between the A and B pillars into the vehicle. The correct position at which the car body…

The temperature behavior of brakes plays a major role in vehicle development. In particular, the duration of heating and cooling of the brake discs provides information about the efficiency of the brake system. In test bench and road tests,…

In the automotive industry, testing the chassis is a prerequisite for driving safety. Here, sensors are required which can also withstand the high demands of road tests. For example, draw-wire sensors are mounted in parallel to the shock…

In the assembly line of a well-known German car manufacturer, similar car interior parts must be differentiated from each other based on the respective seam color. Previously, professional testers have visually checked the seams. In order to…

colorSENSOR CFO sensors from Micro-Epsilon are ideally suited to this kind of precise color comparison measurement as they reliably recognize different colors while enabling 100% quality control. The sensors are calibrated once to the prevailing…

Color and intensity of vehicle lights must be reliably inspected prior to assembly and delivery. Homogenous distribution of light should also be ensured with fluctuating LED batches. The colorCONTROL MFA is a special LED test system designed to…

Before installing front aprons, Micro-Epsilon color sensors check if the color of the attachment matches the body color. Different color groups can be defined to cover all coatings.

Car attachments such as parking sensors are painted separately. However, during assembly there must be no difference in colour between the parking sensor and the bumper, which means the two colours must be identical. The colorSENSOR from…

After the oil has been filled by a dispenser machine, an ILD1420-200 measures the level. If this is less than 4 mm or if the sensor was not filled at all due to production errors, it is evaluated as NOK and sorted from the production line. Since…

In order to avoid corrosion, continuous and error-free corrosion protection is a critical factor in the painting process. As the thickness of the applied painting on burrs can only be determined under challenging limitations, it is a decisive…

For fully automatic defect detection on car bodies and attachments, the reflectCONTROL inspection system is used. The system projects a striped pattern onto the surface. Deviations caused by defect are recorded with two cameras and evaluated via software.
