You are here: Automatic Riveting on Energy-Storage Battery-Pack & PACK Lines: Trays, Brackets and Cabinets - BISUDI
Energy-storage industry expansion drives strong demand for structural-part manufacturing. From cell grouping and module PACK to battery trays and storage-cabinet frames, large amounts of aluminum profiles and thin steel/aluminum parts need reliable joining; these parts sit next to cells and are highly sensitive to heat and deformation, so riveting as a cold-joining process is rapidly gaining use on energy-storage lines.
I. Joining characteristics of energy-storage structural parts
Energy-storage products have three distinct joining characteristics: first, they areheat-sensitive- battery trays and PACK structures are close to cells, where welding heat input and spatter pose safety and quality risks, while cold riveting has no thermal deformation; second, there ismuch aluminum- trays generally use an aluminum-profile + aluminum-plate weld/rivet-built structure, and welding aluminum demands high worker skill with time-consuming deformation correction; third, there arelarge cabinets with many points- storage-cabinet and outdoor-cabinet frames and doors carry dense rivet points, where manual work is inefficient and prone to missed rivets.
II. Typical application areas
| Component | Joining Content | Recommended Process |
|---|---|---|
| Battery tray | Aluminum-profile frame, base plate, reinforcing beams, lifting-point brackets | Structural rivets + automatic riveting/robotic cell |
| PACK module structure | End plates, side plates, pressure plates, acquisition-part brackets | Auto-feed riveting, rivet nuts |
| Electrical mounting plate | Busbar brackets, internal-thread fixing of electrical components | Hexagonal/knurled rivet nuts |
| Storage cabinet | Frames, doors, shelves, lifting parts | Handheld auto-feed riveting, fixed special machines |
| Outdoor protection parts | Covers and waterproof areas requiring sealing | Blind nuts + sealing structure |
III. Process and quality-control points
First, choose fasteners by load: use structural rivets for main frame joints and rivet nuts where subsequent screw assembly is needed; for the type comparison seeWhat Types of Rivet Nuts Are There; second, strictly follow the spec table for pre-holes and plate thickness, and confirm back-side support at aluminum-profile cavities to prevent bulging deformation; third, perform pull-out and shear tests on key joining points and keep first-article and sampling records; fourth, enable the equipment's counting/miss-proof function so the rivet-point count per tray/cabinet matches the program setting, with automatic missed-rivet alarms; fifth, for large parts such as trays, robotic or gantry automatic cells are recommended, while cabinets and doors are more flexible with handheld auto-feed guns.
IV. Line-configuration advice
Energy-storage products have relatively concentrated models and large single batches, suiting a dedicated-line approach: tray lines center on fixed/robotic cells with fixtures to ensure point consistency; PACK and cabinet lines center on handheld auto-feed equipment with workers moving along stations, where one machine replaces about 3 workers' repetitive riveting labor; after-sales, rework and prototype areas keep pneumatic tools.

Energy-Storage Riveting FAQ
Energy-Storage Industry FAQ
Choosing structural rivets by spec, controlling hole diameter and plate thickness, and verifying with pull-out tests, riveting's anti-vibration and anti-loosening performance has long been proven in automotive and energy-storage scenarios.
Outdoor and humid environments call for electrochemical compatibility; aluminum or stainless rivets with matched surface treatment are options, recommended by the manufacturer per the use environment.
Cabinet lines center on handheld auto-feed guns - nails are fed through the tube to the gun head and workers operate around the cabinet without moving the workpiece.
Models with counting and error-proofing can tally rivets and flag missed ones; fixed/robotic solutions needing point-by-point traceability can specify this at customization.
Yes; the manufacturer can bring equipment to the factory to sample on tray or cabinet samples and measure cycle and pass rate.

V. How to ensure capacity flexibility during expansion
Energy-storage orders fluctuate markedly, and won projects often require concentrated short-term delivery. Line planning should use a "fixed + flexible" mix: core large parts such as trays use special machines or robotic cells to ensure cycle and consistency, while PACK, cabinets and accessories use handheld auto-feed equipment, which is not tied to a single product and can be redeployed to different stations as the order mix changes, avoiding idleness in low season. When introducing a new project, first have the equipment maker complete process verification and cycle calculation with samples, then decide the number of special machines to avoid excessive one-off investment. On the personnel side, automatic equipment simplifies the process to loading/unloading and gun-pulling, so new workers can take post after short training, effectively coping with expansion-phase hiring pressure; for training and onboarding time seeIs an Automatic Riveting Machine Hard to Operate。
