What is the working principle of the automatic lift transfer window?
What is the working principle of the automatic lift transfer window?The working principle of the automatic lifting transfer window is mainly realized through the coordination of the three core modules of the drive system, intelligent control, and sealing and purification, as follows:First, drive system: mechanical transmission to achieve smooth lifting Power source Two-axis servo motors (such as the Hennessy 60 servo motor system) or DC motors provide precise driving force. Transmission methods include rack and pinion drive (low noise) or screw drive (significant thrust), to ensure that the sash lifting speed is stable (0.1-0.3m/s). Executive mechanism The rotation of the motor is converted into vertical motion through a connecting rod mechanism or a synchronous belt, which drives the sash to slide along the track. For example, the electric transfer window can be opened and closed in 3 seconds, and the operating noise is less than 65 decibels. Second, intelligent control system: the core of safety and automation Sensors and logic control Infrared anti-pinch hand sensing: obstacle identification accuracy ≤5mm, the object immediately stops moving when detected. Rain sensing: Automatically close the window through the rain sensor (threshold can be set). Environmental monitoring: Integrated temperature and humidity sensor, real-time feedback, and clean room parameters. Interlock mechanism Electronic interlock (magnetic lock pull ≥ 60) or mechanical interlock, to ensure that both sides of the door can not be opened at the same time, in line with GMP double-door linkage standards. Some high-end models support face recognition or fingerprint verification to achieve permission control. Remote control Support Wi-Fi/Bluetooth connection, remote operation through mobile APP or central control system, response time ≤0.5 seconds. Third, sealing and purification: maintain a high cleanliness environment Physical seal The food-grade silicone seal (IP54 protection class) is tightly fitted to the door frame to prevent contaminants from entering. Laminar flow design (wind speed 0.38-0.57m/s) with H14 high-efficiency filter to ensure the cleanliness of class B or higher. Purification function Built-in UV germicidal lamp (wavelength 253.7nm), irradiance ≥45μW/cm², can be regularly sterilized (15-30 minutes). Optional air shower module (wind speed 25m/s), before transfer to the surface of the goods to blow dust. 4. Workflow example Trigger signal: Personnel sends open instructions through buttons, sensors, or mobile apps. Motor start: A servo motor drives the sash up or down at a preset speed. Safety detection: Infrared sensors continuously monitor obstacles and immediately stop when obstructed. Interlock protection: When one side door is opened, the other side is locked by an electromagnetic lock. Completion of transmission: After the door is closed, the ultraviolet lamp automatically starts disinfection, or the air shower system works. 5. Optimization design in application scenarios Medical field: Rapid delivery of sterile instruments (for example, a hospital in Guangzhou delivers 200 + times a day, increasing efficiency by 40%). Pharmaceutical industry: Laminar flow transfer window combined with H14 filter ensures zero contamination in Class A clean area. Electronic Manufacturing: Explosion-proof transfer window is ATEX certified for use in flammable gas environments. Through the integration of the above technologies, the automatic lifting transfer window strictly controls the pollution risk of the clean room while realizing the efficient delivery of goods, and has become a key equipment in medical, pharmaceutical, electronics, and other industries. |
