AI Technical Summary
The existing ultrasonic welding equipment for cross-flow fan blades is a single-station system with a long welding cycle, resulting in low welding efficiency, high labor costs, and a serious impact on production efficiency.
The design incorporates a dual-station ultrasonic automatic welding equipment for cross-flow fan blades. It employs a dual-station rotary product positioning unit and an ultrasonic welding unit to separate the welding process from the workpiece material handling process, allowing them to be completed in parallel. The equipment combines a vision camera and a light source to identify the workpiece angle, and a cylinder-driven system removes defective products, enabling automatic sorting.
It greatly shortens production time, saves equipment and labor costs, and improves product qualification rate, enabling real-time correction before welding and automatic sorting after welding.
