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.
本发明涉及一种材料舱外暴露装置,安装在在轨航天器的外侧平台上,包括底座、载荷中心框架、安装支架、若干实验箱和四自由度巡检机械臂,底座的一边缘上预留有一缺口;载荷中心框架垂直固定安装在底座的中心位置;安装支架上对应底座的每条边分别设有至少一个装配口;若干实验箱分别可拆卸的安装在装配口内;四自由度巡检机械臂的一端转动连接在载荷中心框架顶端,另一端活动的位于缺口内;四自由度巡检机械臂上滑动安装有图像采集装置;其中,四自由度巡检机械臂的另一端移出缺口后,实验箱打开,实验箱的暴露面垂直于底座并与对应的底座的边平行;四自由度巡检机械臂带动图像采集装置绕载荷中心框架转动,并依次对若干实验箱的暴露面进行巡检。
