Brief Introduction


The introduction of automatic welding equipment specifically designed for centrifugal fan shells brings a transformative change to the industry. This equipment enables automated and unmanned fan manufacturing, significantly improving welding quality and efficiency while reducing the need for manual labor. The welded seams are firm and visually appealing, eliminating the need for manual polishing. This advancement allows customers to streamline their processes, addressing the labor-intensive and challenging nature of traditional centrifugal fan manufacturing.

Operating the equipment is user-friendly and does not require extensive training. The equipment incorporates a laser machine vision system for automatic seam-finding. All welding operations are contactless and free of jitter, ensuring the reliability and aesthetic appeal of the welding process. This technological advancement in automatic welding equipment for centrifugal fan shells revolutionizes the industry by enabling automated, efficient, and high-quality fan manufacturing.

Visual Laser Guidance System

The vision system incorporated in the machine represents cutting-edge technology in the field of control. In welding applications, this system adds intelligence and user-friendliness to automatic welding equipment.

Using laser technology, the vision system automatically detects and locates the weld seam’s position, including its front, rear, and height. Even in the presence of irregular Archimedean spiral lines or if the fan shell is unevenly positioned, the visual placement does not hinder the manipulator’s ability to accurately track the weld seam. This ensures precise and reliable welding, regardless of any irregularities or variations in the fan shell’s shape or positioning.

In the process of seam searching, laser light source is used to guide the seam. Refer to the following figure:
