Global OEMs and Tier-1 PACK assembly contract manufacturers face severe cost, quality, and cycle-time constraints when scaling light electric vehicle (LEV) battery lines. Manual steps and outdated resistance welders cause high internal scrap rates and safety recalls.
Manual application of positive terminal highland barley insulation paper is labor-intensive, error-prone, and severely restricts line throughput (maximum 800-1,200 pcs/hour per worker), causing severe bottlenecks ahead of automated welding stations.
High-frequency contact causes electrode pin carbonization, oxidation, and mushrooming tip deformation. Inconsistent contact resistance directly triggers cold welds, burn-throughs, micro-short circuits, or thermal runaway risks in E-Bike battery modules.
Batches of un-sorted cylindrical cells with varying open-circuit voltages (OCV) and internal resistance (ACIR) lead to uneven heat dissipation, uneven tab nugget depth, and accelerated module degradation under intense AGV/E-Scooter vibration cycles.
A seamlessly synchronized production flow integrating cell sorting, insulation pasting, high-speed pneumatic handling, and closed-loop inverter spot/laser welding for 36V, 48V, 60V, and 72V light electric mobility battery packs.
High-accuracy 5-channel to 10-channel automatic sorting systems. Equipped with precision internal resistance meters (accuracy ±0.1% ACIR) and OCV testing (±0.05mV) to bin 4,500-6,000 cells/hour, guaranteeing cell consistency before tab attachment.
Roll-fed positive terminal insulation sticker pasting with integrated visual inspection for concentricity and adhesive coverage. Delivers up to 5,000 pcs/hour with zero cell jacket damage, fully replacing 3-4 manual assembly operators per shift.
Servo-driven dual-head spot welding with gantry XY motion or dual-sided rotary indexing. Features real-time constant current/voltage switching, pneumatic independent floating heads, and zero-spatter copper-nickel tab bonding.
Closed-loop Z-axis stroke tracking automatically offsets electrode mechanical wear, maintaining identical contact pressure (0.1N precision) across 50,000 continuous weld cycles.
Dynamic monitoring of discharge impedance and voltage waveforms. Automatically halts production and alerts technicians when electrode tip burn limits are reached, completely eliminating cold weld defects.
Instantaneous multi-parameter energy profile presets allow continuous welding of mixed nickel-plated steel tabs, pure nickel strips, and copper-nickel composite busbars in a single setup.
Designed specifically for Tier-1 contract manufacturers demanding relentless 24/7 uptime, uncompromising safety compliance, and low cost of ownership.
