You are here: Automatic Riveting Applied to Energy-Storage Battery-Pack & PACK Lines: Trays, Brackets and Cabinet Enclosures - CHANRUI
The expansion of the energy-storage industry drives strong demand for structural-part manufacturing. From cell grouping and module PACK to battery trays and storage-cabinet frames, large volumes of aluminum profiles and thin steel/aluminum parts require reliable joining; these parts sit beside cells and are highly sensitive to heat and deformation, so riveting as a cold-joining process is rapidly gaining ground on energy-storage lines.
I. Joining characteristics of energy-storage structural components
Energy-storage products show three distinct joining characteristics: first, they areheat-sensitive- battery trays and PACK structures sit close to cells, where welding heat input and spatter pose safety and quality risks, while cold riveting causes no thermal deformation; second, there isa lot of aluminum- trays usually use an aluminum-profile + aluminum-plate weld/rivet-built structure, and welding aluminum calls for high worker skill with time-consuming deformation correction; third, there arebig cabinets with dense points- storage-cabinet and outdoor-cabinet frames and doors carry dense rivet points, where manual labor is inefficient and prone to missed rivets.
II. Typical application fields
| Part | Joining details | Suggested process |
|---|---|---|
| Battery trays | Aluminum-profile frame, base plate, reinforcing beams and lifting-point brackets | Structural rivets + automatic riveting / robotic cell |
| PACK module assembly | End plates, side plates, pressure plates and acquisition-part brackets | Auto-feed riveting and rivet nuts |
| Electrical mounting plates | Busbar brackets and internal-thread fixing of electrical components | Hexagonal or knurled rivet nuts |
| Storage cabinets | Frames, doors, shelves and lifting parts | Handheld auto-feed riveting and fixed special machines |
| Outdoor protective parts | Covers and waterproof zones that require sealing | Blind nuts + sealing structures |
III. Process and quality-control key points
First, choose fasteners according to load: use structural rivets for main frame joints and rivet nuts where later 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, run 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 that 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 recommendations
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 from station to station, where one machine replaces about 3 workers' repetitive riveting labor; after-sales, rework and prototype areas continue to use pneumatic tools.

Energy Storage Riveting FAQ
FAQ on the Energy-Storage Industry
When structural rivets are chosen by spec, hole diameter and plate thickness are controlled, and pull-out tests are carried out, riveting's anti-vibration and anti-loosening performance has long been proven in automotive and energy-storage settings.
Outdoor and humid environments require electrochemical compatibility; aluminum or stainless rivets with matched surface treatment are options, recommended by the manufacturer according to 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 the missed ones; fixed/robotic solutions that need point-by-point traceability can specify this at customization.
Yes; the manufacturer can bring equipment to the factory to sample on tray or cabinet specimens and measure the cycle and pass rate.

V. How to ensure capacity flexibility when expanding
Energy-storage orders fluctuate markedly, and won projects often require concentrated short-term delivery. Line planning should adopt 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 the low season. When introducing a new project, first have the equipment maker complete process verification and cycle calculation with samples, then decide how many special machines to buy so as 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 hiring pressure during the expansion phase; for training and onboarding time seeIs an Automatic Riveting Machine Hard to Operate。
