Automotive & EV Manufacturing
Sub-millimeter weld verification and battery cell defect inspection
Vehicle and electric powertrain production lines require sub-millimeter visual precision. Toplens deploys on-premise neural models directly to line-side industrial PCs to verify weld seams, measure panel flushness, and scan prismatic battery cells without sending frames to the cloud.
Automotive production lines run at takt times as low as 45 seconds per vehicle. A single missed weld defect or misaligned battery tab can trigger a warranty recall costing tens of millions across an entire model year.
4 Common Operational Challenges
Real-world issues that standard manual monitoring and traditional security routines miss daily.
Undetected Robotic Weld Porosity & Spatter Defects
Spot welders produce microscopic porosity, burn-through, and undercut defects across hundreds of welds per chassis that are invisible to the naked eye.
EV Battery Cell Micro-Defects Escaping to Pack Assembly
Tab misalignment, foil wrinkles, and micro-scratches on prismatic cells go unnoticed before cells are sealed into battery packs.
Body-in-White Panel Gap & Flush Inconsistency
Door, hood, and trunk panel clearances drift outside tolerance across the shift, creating visible cosmetic inconsistency.
Assembly Worker Ergonomic & PPE Non-Compliance
High-cycle robotic assembly cell workers skip wrist protection and eyewear during repetitive fastening tasks.
4 Targeted Operational Solutions
How Toplens connects directly with existing facility streams to resolve each vulnerability.
Full-Coverage Robotic Weld Bead Classification
Cameras mounted on weld-cell gantries capture every spot weld post-formation, instantly flagging porosity or burn-through to the line PLC for rework routing.
High-Speed Line-Scan Battery Pouch Inspection
Line-scan cameras image every cell at formation speed, rejecting units with tab misalignment or foil wrinkles before pack integration.
Continuous Stereo-Vision Gap & Flush Verification
Stereo laser triangulation rigs measure every door and hood clearance in 3D coordinates on every vehicle, feeding drift data back to tooling control.
Automated Ergonomics & Wrist/Eyewear PPE Audit
Cell-side cameras verify wrist wraps and protective eyewear at every cycle, logging compliance data directly to the plant HSE dashboard.
4 Core Applications for Automotive & EV
Tailored capabilities engineered around standard operations across your key zones.
Robotic Weld Bead Inspection
Classifies porosity, spatter, burn-through, and undercut defects across spot welds per vehicle chassis.
EV Battery Pouch Surface Scan
High-speed line-scan detection of tab misalignment, micro-scratches, and foil wrinkles down to 25 microns.
Body-in-White Gap & Flush Analysis
Stereo-vision laser triangulation calculating door and hood clearance in 3D coordinates.
Assembly Ergonomics & PPE Check
Verifies wrist wraps, protective eyewear, and posture safety across robotic assembly cells.
Facility Leadership Feedback
How facility leadership and operations teams experience Toplens in active environments.
“We used to sample-check 3% of our spot welds. Toplens now inspects every single one of the 240 welds per chassis at full line speed, and our warranty claims tied to structural welds dropped to effectively zero.”
“Battery cell defects are non-negotiable in EV manufacturing. Toplens catches tab misalignment and foil wrinkles at our full 180 cells-per-minute formation speed, something no human inspector could sustain.”
“Panel gap drift used to be caught reactively during hourly checks, by which point hundreds of vehicles had already passed. Real-time stereo-vision flush measurement lets us correct tooling before a single defective panel ships.”
“Automated ergonomics tracking on our high-cycle fastening cells reduced reported wrist strain incidents by nearly half within the first quarter.”
