Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054]It should be noted that when a component is said to be "mounted on" another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "set on" another component, it can be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there ...

Abstract

The invention relates to a preparation method of a gecko-foot-imitating surface microstructure based on a femtosecond laser processing technology. The preparation method comprises the following steps that S1, a femtosecond laser processing platform is built; S2, a focal plane is determined; S3, working parameters of marking software are set, and primary marking is carried out. S4, the placement position of a sample is changed, secondary marking is carried out, and the gecko-foot-imitating microstructure surface with cilia is obtained. S5, working parameters of the marking software are adjusted, marking is carried out, and the gecko-foot-imitating layered microstructure surface with the cilia is obtained; and S6, the sample of the gecko-foot-imitating layered microstructure surface with the cilia is placed in the direction perpendicular to the second position, and marking is carried out to obtain the gecko-foot-imitating number sign-shaped microstructure surface with the cilia. According to the preparation method disclosed by the invention, the ablation and sputtering areas of femtosecond laser and substance action are relatively small, the thermal effect influence is small, the integrity of a material structure can be kept, the processing precision is high, the operability is strong, and the gecko-foot-imitating surface microstructure with good material structural integrity can be accurately and efficiently prepared.

Description

technical field [0001] The invention belongs to the technical field of bionic structure preparation in micro-nano processing, and in particular relates to a method for preparing a surface microstructure of imitation gecko feet based on femtosecond laser processing technology. Background technique [0002] In industrial production and daily life, the commonly used adsorption methods mainly include vacuum adsorption, mechanical clamping, electrostatic adsorption or magnetic adsorption. Due to the complex design of the mechanical clamping structure, electrostatic adsorption and magnetic adsorption have specific requirements for the adsorbed material. Therefore, vacuum adsorption is currently the most commonly used and most mature adsorption method. However, when vacuum adsorption is applied to adsorb precision devices, the surface of the device is often damaged to a certain extent due to excessive suction. Therefore, in order to solve how to achieve a large adhesion force unde...
