Glass workpiece sealing packaging box

Abstract

The invention relates to a glass workpiece sealing packaging box. The glass workpiece sealing packaging box comprises a packaging box body, a workpiece protection block, nitrogen filling valve cores, a silica gel sealing strip and an organic glass cover plate, wherein the packaging box body is formed at a time from a whole piece of PE or POM material by adopting a numerical control machining method; the inner space of the box body is designed according to the actual shape of a glass workpiece stored in the box body; pick-and-place openings are formed in the periphery of a placement platform of the glass workpiece, so that a packaging worker can conveniently reach out the hands when picking and placing the glass workpiece; the workpiece protection block is used for fixing the glass workpiece and preventing the glass workpiece from being damaged due to movement in the packaging box body during packaging; a sealing groove is formed in the upper surface of the box body; the gap between the cover plate and the box body is eliminated by using the silica gel sealing strip during packaging; as the cover plate is made from an organic glass material, the internal situation of the packaging box body can be checked conveniently; and besides, as the valve cores are arranged on the two sides of the packaging box body separately, the packaging box body can be filled with nitrogen to protect the glass workpiece. The glass workpiece sealing packaging box has the advantages as follows: the universality is strong, the precision is high, the sealing property is good, the cost is low, and both processing and disassembling are convenient.

Description

technical field [0001] The invention relates to a sealed packaging box, in particular to a sealed packaging box for glass workpieces. Background technique [0002] The high-precision processing of optical components puts forward high requirements on the packaging of glass components. In order not to damage the optical accuracy and coating layer of the glass workpiece surface, the packaging box used is required to be well sealed and have dust-proof and moisture-proof functions. [0003] One of the existing packaging methods for glass workpieces is to use blister packaging boxes. This method needs to make molds in advance according to the shape of the workpiece to be packaged and then process a blister packaging box of the corresponding shape. Therefore, this packaging box fits closely with the packaging. , Good fixing effect. However, the manufacturing cost of this kind of mold is quite expensive. Sometimes there are only one or two components of a certain size, but it costs...
