NEV & Auto-Part Automatic Riveting Machine · Battery Box / Seat / Structural-Component Riveting Solutions
The three-electric systems, lightweight bodies and interior/exterior trim of new-energy vehicles create heavy demand for joining thin sheets, aluminum profiles and dissimilar materials that traditional welding alone cannot fully cover, so automatic riveting machines, automatic rivet nut tools and robotic riveting stations are being adopted more and more on auto-part lines. Battery boxes and pack housings, battery trays, PACK brackets, seat frames, doors and impact beams, and charging-pile cabinets widely use blind rivets and rivet nuts, with strict demands on pull force, sealing, error-proofing and traceability. CHANRUI supplies robotic riveting stations, in-line counting riveting machines and rivet nut tools, with free on-site trials for auto-part enterprises nationwide.
Typical Workpieces & Selection
| Workpiece | Common Fasteners | Recommended Solution |
|---|---|---|
| Battery boxes, battery trays | M5-M10 rivet nuts, Ø4.8-6.4 rivets | Robotic / gantry riveting station |
| PACK brackets, module structural parts | Aluminum rivets, sealed rivets | In-line counting riveting machine |
| Seat frames, door impact beams | Ø4.0-4.8 rivets, rivet nuts | Dual-gun / fixed models |
| Charging-pile cabinets | Rivets + M5-M10 rivet nuts | Riveting machine + rivet nut tool |
Automotive-grade Joining Focus
| Focus Area | Details | CHANRUI Approach |
|---|---|---|
| Stable cycle time | Capacity planned backward from cycle time | Around 80/min, with consistent and repeatable parameters |
| Error-proofing & traceability | Missed rivets at key points affect safety | Count to target, incomplete alert, IO to MES |
| Sealing & waterproofing | Strict demands for battery parts | Sealed rivet + structural adhesive combination verified |
| Fast changeover | Many new models, tight validation timelines | Feed tracks, gun heads and programs change over fast |
Solution Highlights
For mass production, trays and battery boxes use robotic/gantry stations with sealing and pull-off verification; seat frames run in-line counting dual-gun models; charging-pile cabinets use a riveting machine plus rivet nut tool combination. We suggest bringing the equipment supplier in as early as the quotation stage of a new project, so hole positions, fastener specs and automation accessibility are designed into the process together.
After adopting robotic riveting stations and in-line counting dual-gun riveting machines, missed rivets at key points on battery boxes and seat frames fell to zero with traceable data, labor per line dropped by about half, and the plant passed the OEM system audit and won new orders.
FAQ
Yes. For auto-industry clusters nationwide, an engineer can bring a matched model to your factory to run samples with real parts and test cycle time and pull force on site; this is normally free of charge.
In-line and robotic models supply IO signals and counting data, and can interface with PLC/MES according to the customer's system to achieve error-proofing and traceability.
By combining sealed rivets, rivet nuts, structural adhesive and sealing rings; during the trial we run sealing and pull-off verification against the battery-box process.
