Electric vehicle assembly line

This production line is a set of fully automatic, intelligent, flexible vehicle assembly equipment specially built for the new energy vehicle industry. Adopting a modular design concept and integrating advanced technologies such as industrial robots, intelligent conveying equipment, and digital management and control equipment, it can realize the whole-process automatic production from body welding, chassis assembly, power integration to vehicle off-line.The production tact is flexible and adjustable, supporting multi-vehicle collinear production, with an annual capacity of 100,000–150,000 units. It is a core equipment solution for new energy vehicle manufacturers.

Core Technical Features

1. Intelligent Suspension Conveying EquipmentThe core of the production line adopts overhead friction conveying equipment (EMS). The yellow gantry suspension mechanism lifts the body under the track to realize efficient transfer between stations.Compared with traditional ground conveying lines, this equipment has the advantages of small space occupation, flexible layout and low noise. The conveying speed can be adjusted steplessly according to process requirements, with positioning accuracy up to ±2mm, ensuring precise connection of assembly operations.

2. Multi-vehicle Flexible Mixed-line ProductionThrough the deep integration of programmable logic controller (PLC) and RFID identification equipment, the production line can automatically identify parameters of different vehicle models and adjust fixtures, robot tracks and process parameters in real time.It supports mixed-line production of multiple platform models such as cars, SUVs and micro electric vehicles. The model change time is shortened to less than 15 minutes, greatly improving equipment utilization.

3. Modular Process LayoutThe production line is divided into three functional modules: interior assembly line, chassis assembly line and final assembly line.

• Interior Assembly Area: Installation of internal parts such as instrument panels, seats and wire harnesses
• Chassis Assembly Area: Integration of battery packs, motors, electronic control equipment (three-electric equipment) and suspension assemblies
• Final Assembly Area: Tire installation, fluid filling, vehicle inspection and other final processes

All modules are seamlessly connected by intelligent AGV or suspension conveying equipment, supporting future capacity expansion and process upgrading.

1. Green Intelligent ManufacturingFollowing the concepts of Industry 4.0 and dual-carbon strategy, the production line is equipped with energy management equipment to monitor energy consumption data of each station in real time.Low-noise transmission parts and energy-saving motors are adopted, and workshop noise is controlled below 75 decibels. Paperless operation is realized in the assembly process. Electronic process instructions are pushed through MES equipment to reduce resource consumption.

Key Equipment Configuration

Digital Management and Control Equipment

The production line is equipped with manufacturing execution equipment (MES) to realize digital management of the whole production process:

• Real-time Monitoring: Display output, tact, equipment status and quality data through large-screen dashboards
• Quality Traceability: Automatic data collection at key processes, establishment of single-vehicle files, realizing full life cycle traceability
• Predictive Maintenance: Early warning of fault risks based on equipment operation data analysis, reducing downtime loss
• Intelligent Scheduling: Automatically optimize production plans according to order demands to improve delivery efficiency

Application Scenarios and Value

This production line is suitable for large-scale manufacturing of battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV), especially for the production of A00-class to B-class models.By introducing this production line, enterprises can achieve:

• Production efficiency increased by more than 30%, and single-vehicle manufacturing hours reduced to 15–20 hours
• Product defect rate reduced to below 0.5%, and quality consistency significantly improved
• Labor cost reduced by 40%, realizing the operation mode of Dark Factory
• Rapid response to market demand, and new product introduction cycle shortened by 50%
