Adhesive Application and Sealing Solution

Detailed Documentation

Background and Issues: Global competition in the automotive manufacturing industry continues to intensify, and requirements for sealing and corrosion protection in coating processes are constantly increasing. As the coating process is the环节 with the highest sealing requirements among the four major processes of stamping, welding, coating, and assembly, its quality directly relates to the durability and reliability of the entire vehicle. However, many enterprises still focus on the functional realization of adhesive application, with obvious shortcomings in automation and process consistency. Many production lines still rely on traditional manual or semi-automatic adhesive application methods, restricting further improvement of production efficiency and quality.

Core Solution and Principle: This system takes 6-axis industrial robots as the core, integrating external linear axes and high-precision adhesive application process equipment (including glue guns, metering cylinders, and pressure regulators) to achieve fully automatic adhesive application in areas such as the vehicle underbody, weld seams, and cavities. The robot is responsible for trajectory movement, while the process system precisely controls the glue dispensing action. Real-time communication with the main controller enables coordinated control of glue gun start/stop, flow rate, and trajectory.

Core Innovation Points/Advantages:

 Based on years of technical accumulation, HIRUN has established its own automated adhesive application process standards and product system, launching a full range of domestically produced core components, including 3D glue guns, metering cylinders, pressure control systems, and hose packages;

 Achieved full-cycle closed-loop capabilities from R&D testing, equipment manufacturing to project delivery and operation maintenance services, significantly enhancing customers response speed and customization level in adhesive automation.

Application Scenarios and Value:

The solution is widely applied to various sealing processes in complete vehicles, including underbody sealing (UBS), cabin sealing (UBC), interior weld seam sealing (ISS), vibration damping (FAD), and water-based sound insulation (LASD) adhesive application scenarios. It helps customers reduce per-unit material consumption by 10%–20% and save per-unit costs by 10–20 yuan.
