The invention relates to the technical field of glove boxes, and discloses a gas replacement device and a replacement method and control method thereof. The gas replacement device comprises a first chamber and a second chamber which are communicated with each other; the air duct system comprises an air inlet module and an air outlet module which are arranged on the inner wall of the first cavity, the air inlet module and the air outlet module are oppositely arranged, and an air duct used for gas replacement is formed between the air inlet module and the air outlet module; the door lock module comprises an inner door and an outer door, the second cavity communicates with the first cavity through the inner door, and the first cavity communicates with the exterior of the shell through the outer door; the control module comprises a gas replacement program used for controlling the air duct system, a door lock program used for controlling the door lock module and an information processing program used for processing information; the air duct system is started and stopped and the inner door and the outer door are opened and closed automatically, manual operation is not needed, the replacement efficiency in the first cavity is improved, and the gas environment in the second cavity is guaranteed.
Description
technical field [0001] The invention relates to the technical field of glove boxes, in particular to a gas replacement device, a replacement method and a control method thereof. Background technique [0002] The gas replacement device in the glove box is a transition device when transferring items to or from the operating device. In order to prevent the external environment from destroying the operating space environment during the transfer of items, a gas with gas replacement function is generally required. Replacement device and a good sealing environment to achieve the purpose of purifying the transfer space. At present, the air inlet and exhaust port of the gas replacement device are generally directly set on the shell, and the air inlet and the exhaust port are manually controlled, so it is difficult to control and open and close the gas replacement device in real time, so that the replacement efficiency during gas replacement The opening and closing efficiency of the ...
