Intelligent robot workstations, intelligent work islands, providing the entire process (cutting, assembly, welding, grinding, inspection, etc.) of intelligent applications for the non-standard metal structure manufacturing industry.

The biggest characteristic of the machinery industry is the wide variety of products and custom parts. This requires true flexible production, because every factory welds different products, and one product may be very different from another.

Traditional robot welding can be difficult to promote in this industry because welding paths usually cannot be reused, and there are often many different products to handle. For many manufacturers, programming and teaching are required for the whole process, which greatly increases the barrier to using robots.

Our solution is a robot smart welding factory based on 3D vision and an intelligent welding system. The vision system takes photos and scans the workpiece, generates a real-time point cloud model, and the intelligent system automatically extracts the weld path from the data. The operator only needs to place the workpiece in front of the robot and click start.

The system can recognize the component, generate the welding path, and complete the welding operation without importing a 3D model or performing complex teaching operations. It greatly lowers the barrier to using robotic welding and makes automation easier for factories producing many different kinds of workpieces.

This is especially suitable for high-mix, low-volume production, non-standard parts, and manufacturers that need flexible welding automation.
