Multifunctional loading unit for objective table of microscope

Abstract

The invention relates to a multi-functional loading device for an object stage of microscopes, which comprises a force sensor, a fixing clamp splice, a moving clamp splice, a micrometer screw rod, and the like; the fixing clamp splice is provided with two long circular empty grooves; a screw goes through the empty grooves to connect the fixing clamp splice and a framework; two roll ball slideways are fixed in a frame slot by screws; the roll balls are installed in the grooves at both sides and are connected with the grooves in a sliding manner; the moving clamp splice is fixedly connected with the force sensor by the screws; a rotation / translation shifting block is fixed with the force sensor by the screws; the micrometer screw rod goes through the framework and is installed on the rotation / translation shifting block; the displacement loading information can be read from the scale on the micrometer screw rod and the force loading signal is sent out by a signal wire connected with the force sensor. The multi-functional loading device of the invention can be universally used in the object stages of Micro-Raman spectroscopy, X-ray diffractometer and various microscopes, the volume thickness is only 16mm and the observation of the microscopic appearance of samples, the collection of diffraction spectrum and the acquisition of stress / strain information are realized when tension and compression load are exerted on the samples.

Description

technical field [0001] The invention belongs to a mechanical device, in particular to a multifunctional loading device for displacement and force sensing for a microscope stage. Background technique [0002] As we all know, various microscopes, micro-Raman spectrometers, micro-infrared spectrometers, XRD diffractometers, etc. are widely used to observe the microscopic morphology of substances and identify material components and types. With the deepening of scientific research, people need to impose loads on the objects studied on the stages of various microscopic instruments to further explore the physical and mechanical properties and behaviors at the microscopic scale. Since the main function of the stage of various microscopic instruments is to place the sample, and it can perform three-dimensional high-precision movement (micron level), so as to observe the morphology of different positions of the sample under the microscope. However, the general characteristics of var...

Problems solved by technology

However, the general characteristics of various microscope stages at present are that the space volume is narrow and heavy objects cannot be placed, otherwise the accuracy of the three-dimensional movement of the stage will be affected.

If it is possible to conduct experiments such as stretching or compression on the sample while observing the microscopic state of the object, it cannot be carried out according to the current design structure of the microscope stage.
