Abstract

The invention relates to a material outboard exposure device which is installed on an outer side platform of an on-orbit spacecraft. The device comprises a base, a load center frame, an installation support, a plurality of experiment boxes and a four-degree-of-freedom inspection mechanical arm, and a notch is reserved in one edge of the base; the load center frame is vertically and fixedly installed in the center of the base; at least one assembling opening is formed in each side, corresponding to the base, of the installation support; the plurality of experiment boxes are respectively and detachably arranged in the at least one assembling opening; one end of the four-degree-of-freedom inspection mechanical arm is rotationally connected to the top end of the load center frame, and the other end is movably located in the notch; an image acquisition device is mounted on the four-degree-of-freedom inspection mechanical arm in a sliding manner; after the other end of the four-degree-of-freedom inspection mechanical arm is moved out of the notch, the experiment boxes are opened, and the exposed surfaces of the experiment boxes are perpendicular to the base and is parallel to the corresponding side of the base; and the four-degree-of-freedom inspection mechanical arm drives the image acquisition device to rotate around the load center frame and inspects the exposed surfaces of the plurality of experiment boxes in sequence.

Description

Technical field [0001] The present invention relates to the related field of material exposure outside a space station, in particular to a material outside exposure device. Background technique [0002] In order to face the needs of future deep space exploration, it is of far-reaching significance to study the in-orbit behavior of materials and the characteristics and changes of materials in basic disciplines. During the missions of the former Soviet Union and the International Space Station, several in-orbit exposure tests of metals and non-metals have been verified, and significant scientific research results have been achieved. my country’s space material exposure is still in its infancy. In order to meet the task requirements of material space exposure, it is urgent to involve a trial of the materials to be exposed that can be repeatedly installed, can be re-locked and released as a whole on rail, and automatically unfolded and closed. / Experiment box. The in-situ on-orbit i...
