Before adopting our automatic connection and disconnection device (auto connector, auto coupler, auto joint), it seems that dust and metal shavings accumulated in the connection part of the APC auto connector, leading to contamination and connection failures. Since our auto connector has a flat touch seal on the connection surface, it is free of irregularities, making it easy to remove dust and metal shavings, thus eliminating the deterioration of hydraulic oil and connection failures. Additionally, contamination and connection failures in the hydraulic piping have been eliminated.

■What is an ALL-PTFE Connector? An ALL-PTFE connector features an internal valve that is integrally molded from PTFE, ensuring that the sliding parts during the opening and closing of the internal valve are isolated from the wetted parts, preventing product contamination. It is particularly suitable for lines following sterilization processes where maintaining a sterile condition is crucial. This product pursues the functions required in manufacturing equipment in this field (safety, cleanability, durability) while also being compact and lightweight. Additionally, since all wetted parts, including the internal valve, are made of PTFE, there is no leaching of metal ions into the process fluids, making it suitable for equipment used with chemicals such as wafer cleaning solutions and substrate coatings in the semiconductor field. ■Features of Nabtesco Service's ALL-PTFE Connector High cleanability ⇒ The internal structure is very simple, with no areas for fluid retention. No need for localized SIP in the shaft ⇒ The internal valve opening and closing mechanism is completely isolated from the wetted parts. Elimination of contamination ⇒ A unique fixation method is employed that prevents bypassing around sealing components. Usable for fluids that are sensitive to metal ion leaching ⇒ Since all wetted parts are made of PTFE, there is no leaching of metal ions. Excellent maintainability ⇒ Achieved compactness and lightweight design compared to conventional valves of the same size.

• Semiconductor inspection/test equipment

【Case Study】 This is a device that allows for the automatic connection and disconnection of the cooling water needed during mold changes in a press machine. 【Before Implementation】 When changing molds, it took a long time to connect and disconnect the piping. Additionally, since the work was done around the press machine, it posed a danger to the workers. A few times a year, there were mistakes in connections or connection failures. 【After Implementation】 By adopting an auto connector, the connection and disconnection work has been automated. It also accommodates large diameter (cooling water) of 80A. The automatic connection and disconnection of air piping utilizing the stroke of the die lifter has reduced setup time and improved productivity.

• Other industrial robots

This is a manual mobile tank cart equipped with an automatic attachment and detachment device (auto connector, auto coupler, auto joint) for the tank bottom. The loading and unloading operations for the tank are automated. The movement of the tank is also made easier with a mobile cart installed under the tank. It can accommodate not only liquids but also powders and slurries. The risk of lot-out during the discharge from the tank is eliminated, freeing operators from heavy labor and hazardous tasks.

• Trolley

We automate the attachment and detachment of hydraulic, electrical, and pneumatic components on the inspection line using automatic attachment and detachment devices (auto connectors, auto couplers, auto joints). By arranging the necessary connectors on the panel, simultaneous automatic attachment and detachment is possible. A centering mechanism can be equipped to match the stopping position accuracy of the inspection pallet (platform). Various utilities such as steam, vacuum, air, electricity, hydraulic, and slurry can be attached and detached simultaneously. We design and manufacture custom solutions according to the customer's equipment situation. Please consider using this for factory automation and unmanned operations!
