Case Study | 3D vision-guided automotive three-way catalytic converter loading solution
In order to achieve exhaust gas purification, almost all vehicles are equipped with three-way catalytic converters. It is the most important purification device installed in the exhaust system of automobiles,which can convert harmful gasessuch as CO,HC and NOx emitted by automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation andreduction. The threeway catalytic converter is generally installed in the bulge of the front section of the exhaust pipe, most of which are cylindrical in the form of cylinders, containing a large number of raremetals inside, and are very expensive.
A three-way catalytic converter of a certainform and specification
Due to the high cost of the threeway catalytic converter, the variety of sizes, and thedifferent incoming methods, the user adopts ALSONTECH 3Dvision system to cooperate with the robot for loadingto realize the automatic production of the whole production line.
Project Challenges
oThe workpieces are transportted by the conveyorbelt, although the speed is not fast, but the positioning accuracy requirementfor the vision system is extremely high, the grabbing rate must be 100%;
oWrong gripping or collision errors are not allowedto avoid damage to the catalytic converter and cause losses;
oAccording to the production requirements, theworkpiece will come one by one or multi-pieces comes together, requiring 3Dvision to obtain and feedback the graspingcoordinates of all workpieces to the robot at one scan;
oAccording to the design requirements of the productionline, it is necessary to be able to realize multiple modes of dynamic graspingand static grasping of conveyor belts to complete the positioning of workpiecesat various speeds.
The project adopts ALSONTECH AT S1000 02B 3Dvision system , which is fixed installed above the conveyor belt. The laserline imaging solution has good environmentaladaptability, and easily meets the requirements of millimeter-level positioningaccuracy on site. The application has been replicated at different sites.
