1) Industry and assembly characteristics: why battery manufacturing relies heavily on “tightening + feeding”

New energy battery-related products (such as battery systems) represent critical high-end assembly scenarios, typically featuring dense fastening points, demanding takt time requirements, and stringent expectations for consistent quality. Leetx solutions are widely applied in high-end manufacturing sectors including NEV three-electric systems. Built on a unified technology platform, Leetx products support fast iteration and deep customization, enabling richer product choices and more agile process response for advanced assembly.

In battery manufacturing and battery system assembly, bolts and screws are widely used for structural fixation, housing/cover assembly, brackets, and accessory installation. Any missing fastener, wrong fastener, or nonconforming tightening result may lead to rework and quality risk. As a result, manufacturers typically focus on:

Stable takt time: reducing non-value-added manual actions such as searching, picking, and aligning fasteners, and shifting takt-time variability from operators to the system.

Consistent quality: delivering stable and controllable tightening results throughout long-run mass production, minimizing human-induced variation.

Process traceability: ensuring that process records for critical joints can be retained and analyzed for quality audits and closed-loop problem solving.

Leetx builds assembly units around tightening systems and automatic screw feeding systems, and supports an approach that links assembly data acquisition, quality traceability, and process optimization—well aligned with the strong requirements for mass-production consistency and traceability in the battery industry.

2) Typical stations and how Leetx is applied (tightening + feeding synergy)

A) Battery system structural joints: housings / covers / frames with multiple fastening points (tightening-centric)

These stations commonly involve multiple bolts/screws per unit, repetitive cycles, and high consistency requirements—typical applications for tightening systems.

How Leetx is applied (tightening first):

Manual, semi-automatic, and fully automatic tightening solutions: matching the customer’s automation level and rollout strategy, supporting phased deployment from pilot builds to mass production.

Station-level modular delivery concept: a production-ready tightening station can be structured around the tightening controller and tightening tool, with necessary station accessories to support stable operation in mass production.

Multi-point coordination (optional): where simultaneous multi-point tightening or higher consistency is required, multi-spindle or synchronized concepts can be adopted to improve efficiency and reduce operator-driven variability.

B) High-frequency small screw stations: brackets, covers, accessories, and fixation points (feeding impact is highest)

Battery system assembly and peripheral stations often feature low-torque, high-frequency fastening with multiple screw variants. Manual handling consumes takt time and increases the risk of wrong screws, missing fasteners, and mixed parts.

How Leetx is applied (feeding + tightening integration):

Automatic screw feeding to reduce non-value-added work: systematizing screw delivery and presentation reduces dependence on operator skill, stabilizes takt time, and lowers the risk of missing/wrong fasteners.

Modular tightening and pick-up concepts for different fixtures and space constraints: module options can include vacuum-type tightening modules, Pick & Place tightening modules, and quick-change Pick & Place modules to adapt to posture, space, and tooling conditions.

Configurable feeding mechanisms and accessories to stabilize feeding: solutions may combine bowl feeders, step feeders, and hoppers, along with accessories such as distribution, cleaning, screw presentation, and screw brakes to improve feeding stability and takt performance. Final selection is recommended to be validated through feedability analysis based on screw characteristics and tooling constraints.
