Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The invention provides an unsealing device for a sealed packaging container, comprising: a tooling flange 1, a positioning column 2, a shaft coupling 3, a positioner 4, a square column key 5, a movement shaft 6 and a controller;

[0029] Coupling 3 is a torque transmission part between tooling flange 1 and square column key 5, and square column key 5 cooperates with coupling 3 to complete the rotation and lifting of the lid of the sealed packaging container;

[0030] The motion axis 6 is used to apply the cover rotation moment when the sealed packaging container is unsealed, and provide the cover lifting force after unsealed;

[0031] Wherein, the shaft coupling 3 is a cylinder installed in the center of the tooling flange, and the height of the cylinder is at least three times the vertical height of the square column key 5; at the center of the sha...

Abstract

The invention discloses an unsealing device and method for a sealed packaging container. A moving shaft is controlled through a controller; a square column key mounted on the moving shaft is matched with a coupling; rotary location of the square column key is achieved through a locator and a locating column; fully-automatic vacuum unsealing can be achieved; and the problems that other impurities are mixed in the unsealing process, and samples from the moon are contaminated are avoided. According to the unsealing method for the sealed packaging container, in the process when a cover body is rotated to be opened, the rotation moment, namely the unsealing moment, of the sealed packaging container is obtained through measurement of rotation motion of the moving shaft; the sealing performance and the leak rate of the sealed packaging container are calculated through the unsealing moment; and performance evaluation of the sealed packaging container is achieved.

Description

technical field [0001] The invention relates to the field of unsealing technology, in particular to an unsealing device and method for a sealed packaging container. Background technique [0002] The Chang'e-5 probe is the first spacecraft developed by my country to implement unmanned lunar surface sampling and return. Among them, the sealed packaging container is one of the core devices of the Chang'e-5 probe. Its function is to undertake the lunar surface samples and deep drilling samples and automatically vacuum-package the samples. After the Chang'e-5 returner transports the lunar samples back to Earth, it needs to open the sealed container containing the lunar samples to analyze and study the lunar samples. The sealed packaging container is a cylindrical structure, including: a container body and a cover body. The opening end of the container body is provided with a knife-edge structure, and an alloy sealing ring is provided in the container cover body. When the cover b...
