Depalletizing and Hanging of Automotive Battery Covers

SIDASA Engineering specializes in the design and manufacturing of surface treatment and coating systems across various sectors, notably in industry, automotive, and aerospace. The company offers solutions such as painting lines, metal and plastic treatments, as well as dip-spin coating and electroplating. SIDASA emphasizes innovation and quality, providing customized solutions to its clients worldwide. It is within this approach that SIDASA contacted INNODURA.

The project involves developing an innovative localization and hanging unit for the surface treatment of car battery covers. This unit integrates two parallel lines for managing the covers, offering the possibility to handle multiple different treatments. The uniqueness lies in the localization of the covers and their automatic hanging on a dedicated gantry before immersing them in the treatment bath. The robot performs these operations with high precision, thanks to an onboard Zivid camera that scans the pickup and drop-off zones, along with the innovative technological solution developed by Innodura, INNOROBOT.
‍
The first function of the INNOPICK module is to localize these covers in 3D on their gantry.INNOROBOT then transmits the pickup vector to the PLC.
‍
The second function is to calculate the feasibility of hooking, as well as the associated transformation. This process presents several significant challenges:

            ·       The size of the objects, spanning several meters, compared to hooks of only a few millimeters
            ·       Low hanging tolerance (<1 mm).
            ·       A large number of hanging conditions
‍
To successfully achieve this complex automatic hanging, INNOROBOT combines several perception and guidance functions:

            ·       Localization of specific features on a part
            ·       Spatial calibration
            ·       3D measurement of the hanging support
            ·       Segmentation and re-localization of the support
            ·       Trajectory correction functions in space
            ·       Communication with the robot
