一种应用于质构仪检测的样品盖板自动控制机构

Abstract

本实用新型公开了一种应用于质构仪检测的样品盖板自动控制机构，涉及质构仪技术领域，设有直线驱动器和导向机构；导向机构包括基座、立柱和滑块；立柱的底端与固定安装的基座固连，滑块与立柱滑动配合安装，两者之间形成垂直于载物台的盖板滑动副；滑块与盖板安装连接；直线驱动器的固定端安装固定，输出端与滑块安装连接，输出驱动滑块沿立柱滑动靠近或远离载物台的直线运动。本实用新型通过直线驱动器驱动滑块沿立柱向上或向下滑动，带动盖板上升或下降，进而实现了盖板对样品的自动下压固定及与盖板样品的自动抬升分离，减少了样品检测前的准备时间，提升了检测效率，并降低了工作人员的劳动强度。
