The invention discloses a multi-station vacuum air exhaust device for an infrared detector. The multi-station vacuum air exhaust device for the infrared detector comprises a main cavity body, a main cavity body sealing valve, a molecular pump, an inserting plate valve, a side drawing valve, a mechanical pump and a front-level pump. The main cavity body is a public vacuum chamber of the whole vacuum air exhaust device. A plurality of external connectors are distributed on the periphery of the main cavity body. The public chamber is divided into a plurality of air exhaust branches. Two air exhaust passages are arranged between the public vacuum chamber of the main cavity body and a pump unit. All the valves are ultrahigh vacuum pneumatic valves. The sealing form of the device is the metal sealing. The multi-station vacuum air exhaust device for the infrared detector is simple in structure and easy to dismantle and install. The number of the stations is many. High level of a vacuum degree can be achieved. Pressure difference of the main cavity body and the station is small. All the selected valves and the pump unit can be automatically controlled.
Description
technical field [0001] The invention relates to a vacuum device, in particular to a multi-station vacuum exhaust device for an infrared detector. Background technique [0002] The reliability requirements of infrared detectors for aerospace applications are high. During the production and development of detectors, some operations such as testing and testing are required for the products. In these processes, it is necessary to provide vacuum environments for infrared detectors. Generally, , the infrared detector is placed in the Dewar to obtain a vacuum environment, and the Dewar vacuum is obtained by an exhaust device. [0003] In the current exhausting devices used in infrared detectors, the exhausting table of single or several stations is mainly used for manual exhausting, the exhausting efficiency is low, the exhausting process between the stations affects each other, and the equipment is self-adaptive. poor ability. The invention provides a new type of multi-station e...
