Embodiment Construction

[0036] The micro gripper with biomimetic superhydrophobic structure and the manufacturing method of the jaw end face thereof of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0037] The micro-gripper with bionic super-hydrophobic structure of the present invention imitates the microstructure of the surface of animals and plants, and uses laser to perform bionic microstructure processing on the end face of the clamp end of the micro-gripper, so that the surface has special wettability, reaching Super-hydrophobic, so as to improve the coefficient of friction at the end of the micro-gripper clamp, reduce adhesion, and have self-cleaning, anti-corrosion, anti-icing, anti-frost and other properties.

[0038] like figure 1 As shown, the micro-gripper with bionic superhydrophobic structure of the present invention includes a base 1 and a clamp 2 connected to the base 1, and the clamp 2 is composed of a left cla...

Abstract

A micro-gripper with a bionic superhydrophobic structure and a method for making the end faces of its jaws. The micro-gripper includes a substrate and a clamp connected to the substrate. The clamp is composed of a left clamp body and a right clamp with the same structure. The body is composed of a piece body, and the left clamping piece and the right clamping piece are symmetrically fixed on the base body by screws. The method includes: grinding and cleaning the end face of the jaw of the jaw head to reduce the roughness Ra of the end face of the jaw to less than 1.5, and then using an ultrasonic cleaner to wash in acetone, ethanol and water for ten minutes each; using a picosecond laser to simulate The micro-nano composite structure on the surface of the lotus leaf is subjected to secondary structure processing on the end face of the jaw; the surface energy of the end face of the jaw of the micro-gripper is reduced. The tongs of the present invention are detachable, and the corresponding tongs are assembled according to different working conditions. The end face of the clamp has a large friction coefficient, low adhesion, self-cleaning, anti-corrosion, anti-icing, anti-frost and other characteristics to improve the performance of the micro gripper.

Description

technical field [0001] The invention relates to a micro gripper. In particular, it relates to a micro-gripper with a bionic superhydrophobic structure and a method for manufacturing the end face of its jaws. Background technique [0002] In recent years, micro-grippers have been used more and more widely. At present, most micro-grippers are processed in one piece, and the end of the jaw cannot be processed, that is, the end face of the clamp cannot be further processed. This design limitation The flexibility of the micro-gripper is compromised. At the same time, the end of the micro-gripper needs to be opened and closed frequently during the working process. The clamps are easy to wear, and once damaged, the entire micro-gripper will be scrapped, wasting manpower and resources. At the same time, the end face of the clamp end of the traditional micro-gripper is easy to absorb impurities, and it is easy to frost or freeze in a low-temperature environment and cannot work norma...
