LIGENT Robotics has successfully developed a high-precision, high-efficiency intelligent spray coating production line leveraging its leading vision-guided technology and automation solutions. The implementation of this project will empower door manufacturers to achieve automated and intelligent transformation of their coating processes, significantly enhancing production efficiency and product quality while establishing a new benchmark for smart manufacturing in the door manufacturing sector.

In this project, LIGENT Robotics delivered a turnkey solution encompassing the manufacturing, installation, and commissioning of vision-guided spray robots and supporting equipment, alongside comprehensive services including operator training and after-sales maintenance. Tailored for composite panel door spraying, the system accommodates door panels up to 2200mm × 1100mm in size and 50mm in thickness, fully aligning with industry specifications.

Compared to traditional manual spraying methods, the core advantage of this intelligent production line lies in its high-precision vision-guided system. The transfer platform is equipped with a 3D line laser sensor that captures a full-image scan of the door panel, precisely calculating Z-axis height differences and XY-axis displacement variations. This achieves guidance accuracy of up to 2mm and surface inspection precision of 20μm during spraying. The vision system transmits data to the robot via Ethernet communication, guiding it to plan the optimal spraying path for uniform and precise coating of door panels. After spraying, the transfer equipment also inspects surface quality and flatness to ensure consistent product quality.

In terms of production efficiency, the line employs a streamlined process design. Operations including door panel loading/positioning, visual scanning, and conveying/spraying are tightly integrated. The theoretical production cycle for a single door panel is only 14-17 seconds, representing a significant efficiency boost over traditional methods. This effectively meets the large-scale production demands of door manufacturers. Equipment hardware configuration is equally meticulously refined, with core components such as servo motors, harmonic reducers, and sensors sourced from internationally renowned brands to guarantee long-term stable operation.

To ensure smooth project delivery and post-commissioning maintenance, LIGENT Robotics has established a comprehensive acceptance and service system. Project acceptance is divided into two phases: preliminary and final acceptance, strictly adhering to technical agreement standards to ensure equipment performance compliance. Additionally, LIGENT Robotics provides a three-day professional training program for enterprise technicians, covering robot teaching programming, fault handling, and system operation. Regarding after-sales service, the equipment comes with a 12-month warranty period, offering free repairs and spare parts replacement during this time to comprehensively safeguard stable production line operation.

The implementation of this intelligent spraying production line marks another successful application of LIGENT Robotics in the door manufacturing industry. Moving forward, LIGENT Robotics will continue to uphold its philosophy of “Intelligent Manufacturing, Making a Difference,” deepening its understanding of industry needs while continuously innovating technologies and products. The company aims to deliver high-quality automation solutions to more manufacturing enterprises, driving the transformation of traditional manufacturing toward intelligent and green development.
