The assembly line is a fully automated assembly system designed specifically for optical modules. It consists of stations for automatic loading and unloading, dispensing, assembly, screw tightening, and inspection, and new stations can be customized according to customer requirements. All equipment can be arranged and combined according to process requirements to seamlessly integrate with other equipment, enabling unmanned operation of the entire production line. Carriers for different models can be quickly switched, and model changes can be accomplished with a single button press to synchronize the entire line. The intelligent calibration and data management system enables the equipment to track and manage production processes while making operation more convenient.
