Problem of depalletizing with anarchic positioning

Context

Major player in the automotive battery industry facing a problem of depalletization by robot

• Problem of positioning of the batteries during palletization or displacement of the pallet which causes difficulties during the depalletization.
• This leads to a production line stoppage and requires the intervention of operators to restart the line.
• Several attempts and search for solutions without success on the part of the industrialist, to mitigate these untimely production stops.

Goal

• 80% reduction in robot downtime

Solution implemented

Implementation of the AX Vision software suite with 3D detection and vision functionalityD

• Compact computer device associated with 3 HD cameras and LED lighting
• AX Vision centralizes the flow of the 3 cameras to make a specific analysis combining standard methods and artificial intelligence.
• AX Vision supports communication with the robot via an industrial PLC

Our goal is to determine for each row of batteries

• vertical and horizontal inclination
• the height
• the position
• the number of batteries
• the status of depalletization
• the presence or absence of protective elements

Specific points

• Control performed in an industrial environment without the possibility of controlling natural lighting
• Control carried out on black and grey batteries of uniform color, generating reflections
