With the explosive growth of the global new energy vehicle (NEV) industry, accelerated model iteration, multi-model line production, and the application of lightweight materials have become mainstream trends in the sector, placing new demands on the customization, flexibility, and mass-production adaptability of welding equipment. Core NEV components such as battery boxes, chassis, frames, and body structural parts are mostly made of lightweight materials including aluminum alloys and high-strength steel. Featuring complex welding processes and high precision requirements, traditional standardized welding equipment can hardly meet the mass-production needs of multi-model and multi-specification components. Jiangsu EUNICE Robotics Technology Co., Ltd. has deeply rooted itself in the NEV welding sector. Relying on its core independently developed technologies and full-process service capabilities, the company creates customized intelligent welding workstations that precisely satisfy the core demands of NEV manufacturers for multi-model mixed-line production, high-efficiency mass production, and high-quality welding, making itself a core partner for the intelligent upgrading of NEV enterprises.

The NEV welding sector faces three core challenges. First, model diversification: structural components of passenger vehicles, SUVs, MPVs, crossover vehicles and other models vary greatly in size and shape, which traditional fixed tooling cannot quickly adapt to. Second, material lightweighting: welding of dissimilar aluminum-steel materials and aluminum plates is prone to defects such as deformation, cracks and pores, imposing stringent requirements on welding processes. Third, high-efficiency mass production: as NEV production capacity continues to rise, production lines must feature high takt time, fast changeover and high stability, while ensuring consistent product quality. Traditional welding workstations are mostly standardized with insufficient flexibility, slow changeover and poor process adaptability, failing to meet the "multi-model, small-batch, high-efficiency" production model of NEVs and becoming a key bottleneck restricting the capacity release and quality improvement of automakers.

EUNICE Robotics has accurately insighted into the needs of the NEV industry, focusing on "customized design, flexible production, intelligent control" to build exclusive welding workstations tailored for NEV manufacturers. Backed by a professional team of more than 70 members (70% R&D personnel and over 72.5% holding bachelor’s degrees or above), the company has joined hands with top domestic universities to build an industry-university-research innovation platform, equipped with full-dimensional R&D capabilities covering machinery, electronics, computing and software. It can provide full-process customized services from solution design, equipment R&D and manufacturing to installation, commissioning and after-sales maintenance according to customers’ requirements on model specifications, component materials, production takt and workshop layout, completely solving the welding adaptation challenges in multi-model mass production.

Targeting the welding demands of core NEV components, EUNICE customized welding workstations have achieved three core breakthroughs. First, flexible tooling with quick changeover: adopting modular fixtures and standardized interfaces combined with robot automatic model switching technology, it shortens model changeover from traditional hours to within 15 minutes, supports co-line production of components for 8–12 models, and perfectly fits multi-model mixed-line mass production. Second, exclusive processes for lightweight materials: relying on the independent patent "An Automated Production Line for Welding Aluminum Plates for Battery Boxes", it innovatively adopts a mode of fixed welding robots plus movable workpieces for bilateral welding, accurately addressing industry bottlenecks of large deformation and difficult penetration control in aluminum plate welding. The weld strength and air tightness reach 100% compliance, meeting the safety requirements of key NEV components such as battery boxes and chassis. Third, intelligent mass-production control: integrated with AI visual positioning, adaptive process parameters, production data monitoring and other functions, it realizes fully automatic and unmanned welding processes, increases single-station productivity by more than 40%, and ensures highly consistent welding quality for every product.

The core advantages of EUNICE customized welding workstations lie in their full-dimensional fit with NEV mass-production demands. In terms of production efficiency, the workstations adopt high-rigid frames and high-precision transmission systems with optimized welding paths, greatly shortening the single-component welding cycle to meet automakers’ high-takt mass-production requirements. In terms of quality assurance, the company has passed ISO 9001 quality management system certification; each set of equipment undergoes strict performance tests and aging tests to ensure 24-hour continuous and stable operation, with the welding defect rate reduced to below 0.3%. In terms of adaptability and expansion, the modular design supports subsequent model iteration and process upgrading without replacing the entire equipment, significantly reducing customers’ technical transformation costs. In terms of service support, the localized service teams built by offices in Suzhou and Shanghai can quickly respond to customer needs and provide 7×24-hour technical support to ensure sustained and efficient operation of production lines.

After years of deep cultivation in the industry, EUNICE customized welding workstations have been widely used in core scenarios such as NEV battery boxes, frames, body structural parts and chassis components, successfully helping many NEV manufacturers realize multi-model co-line mass production. Its products have been exported to Indonesia, the Czech Republic, Russia and other countries, winning recognition and trust from the international market. From small NEV passenger vehicles to large electric commercial vehicles, from aluminum battery trays to steel-aluminum hybrid frames, EUNICE always takes customer needs as the core, continuously optimizes customized solutions, helps customers improve production efficiency by more than 30% and reduce production costs by more than 20%, while achieving comprehensive upgrading of product quality, providing solid support for the lightweight and intelligent production of new energy vehicles.

Facing the broad future of the NEV industry, EUNICE will continue to deepen its presence in the new energy welding sector, and further enhance the flexibility, intelligence and digitalization of customized welding workstations relying on cutting-edge technologies such as industrial large models and AI intelligent algorithms. Adhering to the philosophy of "Innovation-driven, Quality First, Customer-centric", the company will continuously deepen industry-university-research collaborative innovation, break through core technical barriers, improve its product portfolio, provide more competitive customized welding solutions for global NEV enterprises, boost the efficient and high-quality development of the NEV industry, and become a leading enterprise in the field of new energy vehicle welding.
