Nonlinear Acoustic Shear Wave Detection of Zero Gap Kissing Bonds in Encapsulated Packs
Nonlinear acoustic shear wave harmonic detection resolves zero gap kissing bonds in encapsulated battery packs by measuring contact acoustic nonlinearity.
Gantry Inspection
Meaning
Automated movement of sensors or cameras along a bridge-like structure enables the systematic scanning of large workpieces. Gantry inspection provides a stable platform for high-speed imaging or ultrasonic probes to verify the assembly of battery modules. The system governs the spatial accuracy of measurements taken across the entire surface of a pack.
Hardware Configuration
Linear motors drive the carriage along precision rails to achieve sub-millimeter positioning. During a gantry inspection, the system follows a pre-programmed path to ensure every cell junction is checked. Rigid construction minimizes the vibrations that would otherwise blur high-resolution images.
Scanning Throughput
The addition of artificial intelligence allows the system to identify weld defects or alignment errors in real time. Because gantry inspection covers wide areas without moving the part, it maintains the cycle time of a continuous manufacturing line. Sensors often include laser profilers and high-definition cameras.
The data collected during this process is usually stored as a digital twin of the battery pack, allowing for full traceability in the event of a field return. This mapping ensures that every single cell location is documented and verified against the original design specifications.
Calibration Requirement
Regular validation against a reference standard ensures the coordinate system remains accurate. Wear in the drive components can lead to positioning drift over time. Precise homing routines at the start of each shift maintain the integrity of the spatial data.
