The invention relates to a positioning device for rotary lifting of a test box, a rotary lifting mechanism and an exposure device. The positioning device is mounted on a rotary lifting device of the test box. The positioning device comprises: a mounting base mounted on an action execution part of the rotary lifting device of the test box; a supporting rod, wherein one end of the supporting rod isarranged in the mounting base in an axial sliding mode through a spring, and the other end of the supporting rod is elastically supported on the supporting plate under the action of the spring; a plurality of rotary positioning parts arranged on the supporting plate, wherein the rotary positioning parts are respectively positioned around the rotary center of the test box rotary lifting device; a first microswitch mounted on the mounting base and located at the starting end of axial sliding of the supporting rod; and a second microswitch mounted on the mounting base and located at the tail endof the supporting rod sliding in the axial direction. In the lifting process of the mounting base along with the test box rotatry lifting device, the supporting rod slides along the mounting base under the action of the spring, and lifting positioning is achieved by triggering the first microswitch or the second microswitch. The positioning device can achieve accurate positioning of the rotary lifting device.

    本发明涉及一种试验箱旋转升降的定位装置、旋转升降机构以及暴露装置,定位装置安装在试验箱旋转升降装置上;包括:安装在试验箱旋转升降装置动作执行部上的安装座;支杆,一端通过弹簧可轴向滑动的设于安装座内,另一端在弹簧的作用下弹性支撑在支撑板上;支撑板上设有若干旋转定位部,若干旋转定位部分别位于试验箱旋转升降装置旋转中心四周;第一微动开关,安装于安装座上并位于支杆轴向滑动的起始端;第二微动开关,安装于安装座上并位于支杆轴向滑动的末端;其中,安装座随试验箱旋转升降装置升降过程中,支杆在弹簧作用下沿安装座滑动并通过触发第一微动开关或第二微动开关实现升降定位。本发明的定位装置,能实现旋转升降装置的精确定位。
