Abstract
Description
Technical Field
[0001] The present invention relates to the field of nanoindentation testing, and particularly to a stage. Background Art
[0002] Microarray structures on the material surface have received extensive attention from researchers at home and abroad because they can effectively improve the optical properties, wear resistance, wettability, and biocompatibility of materials. At present, a variety of technical methods for preparing microarray structures on the material surface have been proposed, such as nanoimprinting technology, electron etching technology, and laser processing technology. It can be found that although these processing methods can prepare indentation microarray structures, they either require expensive high-precision machine tools, or have low processing efficiency and are difficult to form large-scale and multi-quantity processing, or cannot accurately control the indentation depth.
[0003] During the nanoindentation test, the indentation morphology is often asymmetric. The generation of these asymmetric morphologies is largely due to the non-perpendicularity between the indenter and the specimen. Therefore, the non-perpendicularity phenomenon may have a certain impact on the results. Summary of the Invention

[0020] The following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.
[0021] As Figures 1 - 3 shown, a multi-functional stage for a nano-indentation instrument includes a circular stage 1, a bridge-shaped connecting rod 2 for pulling the stage to tilt, and a bottom power device 3 for tilting the stage in three degrees of freedom. There are three connecting shafts on the circumference of the circular stage 1. The two ends of the bridge-shaped connecting rod 2 are respectively provided with a connecting hole and a connecting shaft. The connecting hole of the bridge-shaped connecting rod 2 is rotationally matched with the connecting shaft of the circular stage 1. The bottom power device 3 is provided with an L-shaped connecting rod 33. One end of the L-shaped connecting rod 33 is provided with a connecting hole. The connecting shaft of the bridge-shaped connecting rod 2 is rotationally matched with the connecting hole of the L-shaped connecting rod 33. The circular stage 1 and the bottom power device 3 are rotationally linked through the connecting hole and the connecting shaft on the bridge-shaped connecting rod 2.
[0022] In this embodiment: As Figure 2 shown, the circular stage 1 includes a bearing plane 10, a connecting slider 11, a guide rail 12, a rocker 13, a first gear 14, a second gear 15, a small connecting rod 16, and a slide rail 17. The two ends of the rocker 13 are respectively provided with a connecting hole and a connecting shaft. The connecting hole of the rocker 13 is rotationally matched with the connecting shaft of the circular stage 1 located at the center of the circle. The connecting shaft of the rocker 13 is rotationally matched with the first gear 14. The first gear 14 meshes with the second gear 15. The connecting shaft of the rocker 13 is rotationally matched with the connecting hole of the small connecting rod 16. The bottom connecting rod of the connecting slider 11 is rotationally matched with the connecting hole at the other end of the small connecting rod 16. The connecting slider 11 is slidably matched with the slide rail 17. The slide rail 17 is slidably matched with the guide rail 12.
[0023] In this embodiment: As Figure 3 shown, the bottom power device 3 includes a bottom central gear 30, a middle central gear 31, a third gear 32, an L-shaped connecting rod 33, an upper central gear 34, and a power device base 35; the bottom central gear 30 is rotationally fitted with a connecting shaft at the center of the power device base 35; one of the L-shaped connecting rods 33 is fixedly connected to the bottom central gear 30 through the through holes of the middle central gear 31 and the upper central gear 34; the middle central gear 31 is rotationally fitted with a connecting shaft at the center of the power device base 35; one of the L-shaped connecting rods 33 is fixedly connected to the middle central gear 31 through the through hole of the upper central gear 34; the upper central gear 34 is rotationally fitted with a connecting shaft at the center of the power device base 35; one of the L-shaped connecting rods 33 is fixedly connected to the upper central gear 34.
[0024] Working principle: First, the microarray structure on the surface of the preparation material is realized through the circular loading platform 1. When the rocker 13 drives the first gear 14 to make a circular motion around the second gear 15, the connecting slider 11 drives the bearing platform 10 to move together. Due to the combined action of the guide rail 12, the small connecting rod 16, and the slide rail 17, the connecting slider 11 moves along a rectangle that is tangent to the inside of the second gear 15, thereby realizing the array indentation of a partial area of the material. Secondly, the three-degree-of-freedom angle adjustment of the loading platform is realized through the power device 3. By rotating the three third gears 32, the bottom central gear 30, the middle central gear 31, and the upper central gear 34 rotate, thereby driving the three L-shaped connecting rods 33 respectively fixedly connected to the bottom central gear 30, the middle central gear 31, and the upper central gear 34 to pull the bridge-shaped connecting rod 2, so that the circular loading platform 1 tilts along three different new axes of the orchard, thereby achieving the purpose of angle adjustment.
