Adhesive application is a core process in new energy manufacturing that integrates both functional and structural purposes. By applying adhesives, sealants, thermal gels, and other compounds along predefined paths on workpieces, it delivers five core values: sealing and waterproofing, bonding and fixing, shock absorption and cushioning, corrosion resistance and insulation, and thermal conductivity and heat dissipation. Different compounds are used for different scenarios: polyurethane sealant for waterproof sealing of battery packs and body welds; epoxy structural adhesive for high-strength bonding of battery cells and components; thermal gel for heat dissipation and cushioning of battery cells; and damping adhesive for vibration and noise reduction in the vehicle body. The precision and consistency of adhesive application directly determine the sealing performance, structural strength, and service life of new energy vehicles, making it an irreplaceable key process in new energy manufacturing.

In the new energy vehicle sector, Eunice’s intelligent adhesive application system covers full-scenario applications and forms a complete process solution.

• Full-process adhesive application for power batteries: thermal conductive bonding between cells, fixed sealing of module frames, waterproof sealing of battery pack housings, and sealing protection of PACK interfaces. It fully ensures the IP67/IP68 sealing rating of battery packs, prevents short circuits caused by rain or dust ingress, cushions the impact of vehicle vibration on cells, and extends battery service life.

• Body adhesive application: sealing of body welds, door frames, sunroofs, as well as glass bonding. It effectively improves body sealing, corrosion resistance and NVH performance, reduces interior noise and prolongs vehicle body service life.

• Other core scenarios: sealing of motor housings, waterproof adhesive application for electronic control units, and bonding of interior components. It covers the full-chain adhesive application needs of new energy vehicle manufacturing.

High-precision automation is the core feature of Eunice’s adhesive application system, which thoroughly solves the precision and efficiency pain points of traditional manual gluing. Centered on 6-axis robots, the system integrates a 3D visual positioning system and a high-precision flow control unit to realize intelligent and precise control over the entire adhesive application process. The visual positioning system collects workpiece profile data in real time, automatically corrects the application path, and compensates for machining and assembly deviations, with a path repeat positioning accuracy of ±0.02 mm to ensure the adhesive bead perfectly aligns with the path. The flow control unit adopts a servo screw pump to achieve precise adhesive volume control with a dispensing accuracy of ±1%, delivering uniform and continuous beads without breaks, overflow or accumulation. The system supports adhesive application on complex curved surfaces and irregular paths, adapting to irregular workpieces such as battery packs and vehicle bodies. It also features real-time bead detection with automatic abnormality alarms, ensuring 100% qualified application quality.

Eunice’s pursuit of precision is reflected in three core dimensions: technology integration, full-process service and quality supremacy.

• Technology integration and innovation: It deeply integrates artificial intelligence, machine vision and industrial large-model technologies to realize intelligent path planning for complex curved surfaces, real-time bead detection and defect identification. It also supports CAD path import and offline programming, quickly adapting to the adhesive application needs of different products and enhancing production flexibility.

• Full-process customized service: The company provides end-to-end support from adhesive selection, process development and equipment customization to installation, commissioning and after-sales maintenance. It tailors exclusive adhesive application solutions based on customers’ application scenarios, compound types and precision requirements, solving all-round problems such as compound compatibility, path optimization and efficiency improvement.

• Quality supremacy: Guided by the ISO9001 quality management system, it strictly controls equipment production and process commissioning quality. Each adhesive application system undergoes long-term aging tests to ensure stable continuous operation, so that every adhesive seam meets the long-term reliability requirements of new energy vehicles and eliminates quality risks such as sealing failure and bonding detachment.

Excellence is measured in millimeters, and comprehensive sealing safeguards safety. With its core advantages of high precision, intelligence and full-scenario adaptability, Eunice’s intelligent adhesive application system has become the preferred solution for adhesive application in new energy vehicles. From the precision sealing of power batteries to the all-round protection of vehicle bodies, Eunice guarantees application precision through technological innovation, strengthens product reliability with quality commitment, and helps customers reduce costs and improve efficiency via full-process services. In the future, the company will continue to iterate adhesive application technology, integrate more intelligent algorithms and sensing technologies, and provide more precise, efficient and intelligent adhesive application solutions for new energy vehicle manufacturing, guarding every point of safety and reliability for new energy vehicles with millimeter-level craftsmanship.
