PVC Seam Inspection

Paintshop PVC Seam inspection

Reliable PVC seams are essential to ensure high-quality results in vehicle production. RTVision is a flexible solution that can be perfectly tailored to different requirements. The system is particularly suitable for paint applications with large coverage areas. In these applications, RTVision reliably detects all PVC seam interruptions and deviations in width and position. The result is 100% quality throughout the production process. It achieves excellent contrast ratios even at long working distances and in stationary solutions.

Car Position Measurement


Robots in the production can only complete their task accurately with a reliable detection of the car body position in the cell.

The ISRA VISION Car Position Measurement (CAPMES) System is the industry standard on the market: it is easy to set up and ensures reliable, precise 3D recognition of the body position and orientation in stop & go operation or line tracking in the cell based on a combination of multiple cameras directed at certain features of the car body (e.g. holes, edges, corners) from various directions.

The 3D position of the body detected by the system is used to provide the off-set data to guide robots accurately in a downstream processing step. As a result, car body tolerances and mechanical position deviations can be compensated perfectly and a wide range of car body types can be accommodated on a single line.

Cosmetic Sealing & Tool Inspection Box

Different car models and complex parts geometries produced on the same line require precise robot guidance for high-quality application of beads. The accuracy of the robot applying the bead significantly increases the quality of the time-consuming sealing process for roofs, doors, hoods and flaps. 

The robot-mounted Q-GAGE3D sensor system determines the position and orientation of part contours for the application of fine and visible seams. The position deviations detected are used to accurately guide robots in the seam application. An additional gap check can be integrated prior to applicating the seam to further ensure the precise process. The Tool Inspection Box (TIB) automatically checks the nozzle for damage after each application to avoid scrap and damage to the car body.

The result is consistent quality, especially for all relevant visible seams.

Paint Inspection

Paint Inspection

The CarPaintVision (CPV) surface inspection system detects and classifies all relevant paint defects on car body surfaces in a cycle-time-neutral manner – on-the-fly or stop & go. With modern hybrid-technology, almost all car paint defects are detected at a rate of well over 98.5%. Inspection data is evaluated in the process cycle using proven algorithms and classified according to individual customer specifications. Defect information is immediately available for continuous optimization of the production process. Optionally, the detected defects can be automatically marked for rework in a downstream station.

Foam Insertion

Foam Insertion

Automotive manufacturers use PU foam to dampen the sound inside a vehicle’s cab and prevent road, wind, and engine noise from entering the vehicle interior. These foams are dispensed  into vehicle pillars inside the car body, doors, fenders, and other cavities with special application systems.

Mobile robot guidance systems enable the fast and accurate application of PU foams by detecting cavity openings unique to each car model. The STEREO3D sensor system determines the position and orientation of objects using identifiable features such as holes. The position deviations it detects are used to guide robots accurately in downstream processing steps. As a result, mechanical position deviations can be compensated perfectly. Furthermore, a wide range of product types on a single line can be accommodated. Depending on the application, multiple sensors can be combined as necessary.

Production Analytics


Ensure that your quality standards are met: With comprehensive visualization, analysis, reporting, and alerting tools, IQ-VIS enables live monitoring of ongoing production. The database system collects, consolidates, aggregates, and analyzes all results from the various measurement systems throughout a production facility.

IQ-VIS is an intelligent toolbox for a wide range of users, such as maintenance, operations, and management. The client-server architecture allows data to be accessed both locally and across plants.

This makes production more transparent and allows emerging trends to be visualized in the shortest possible time. Negative influences on product quality can be addressed immediately before quality problems cause additional costs.
