Vacuum storage cabinet

Abstract

The invention discloses a vacuum storage cabinet. The vacuum storage cabinet comprises multiple storage chambers, microcontrollers, a vacuum pump, a vacuum pipeline, vent valves, deflation valves and vacuum measurement devices, wherein the storage chambers are further provided with vacuum chamber door sensors used for generating vacuum chamber door opening and closing signals and outputting the vacuum chamber door opening and closing signals to the microcontrollers; and the microcontrollers control the vacuum pump to carry out vacuum exhausting on the storage chambers according to the opening and closing signals. The vacuum storage cabinet can automatically keep the interiors of the storage chambers vacuum, vacuum exhausting and illumination inside the storage chambers can be conducted automatically when storage chamber doors are opened and closed, operation is convenient, efficiency is high, labor and energy are saved, dependence on operators is reduced, and damage to objects stored in the vacuum storage cabinet caused by wrong operations of the operators is prevented.

Description

technical field [0001] The invention relates to a vacuum device, in particular to a vacuum storage device. Background technique [0002] Vacuum storage cabinets include vacuum drying cabinets, vacuum storage cabinets, and vacuum storage cabinets. The vacuum storage cabinets make the inside of the cabinets in a vacuum state for item storage. Because the storage environment is in a vacuum state, high cleanliness (class 1000) and low humidity (relative humidity < 1%) in the storage room are guaranteed. Vacuum storage cabinets are mainly used to store optical parts, semiconductor components, metal materials, precision machinery, electronic parts, chemical products, chemical raw materials, rare earth materials, blue film, anaerobic materials, easily oxidized materials, etc., and can also be used for electronic instruments , Dehumidification treatment of components and components. Vacuum storage cabinets can ensure that the stored products are protected from oxidation, discol...

Problems solved by technology

[0008] However, the current common practice of vacuum storage cabinets is to manually control the start and stop of the vacuum pump by the operator. The operator checks the vacuum index on the spot and finds that the vacuum index is lower than the design index. After the index is reached, the vacuum pump is manually turned off to maintain the vacuum pressure, and so on. This operation mode requires on-site personnel to be on duty, and all manual operations are time-consuming and labor-intensive, and the efficiency is not high; and this operation also has the following disadvantages: the operator will store After the items are placed in the storage room, close the door of the storage room, and then manually control the vacuum pump to vacuum the storage room. This operation requires two steps for the operator to complete the storage of the items. Sometimes, the operator will forget Turn on the vacuum pump, in severe cases, it will cause damage to the stored items
