Embodiment
[0025] Example: The micro suction cup of the present invention includes an suction surface 1 on which a plurality of fine hollow suction cups 2 are arranged; the suction surface 1 may be a plane or a flexible curved surface.
[0026] Specific adsorption methods such as figure 1 As shown: contact the suction surface 1 of the micro suction cup with the suctioned surface 3, turn on the vacuum suction system 4, and perform vacuum suction on the hollow suction cup, thereby bonding the two surfaces under negative pressure. A load 5 can be suspended on the adsorbed surface 3 to check the load capacity between the adsorbed surface 1 and the adsorbed surface 3 .
[0027] A preparation method of the micro suction cup of the present invention, such as figure 2 shown, including the following steps:
[0028] (1) Apply photoresist 22 on the cleaned substrate 21 and dry;
[0029] (2) The outer hole pattern of the suction cup is made into a mask plate 23, and the mask plate 23 and the p...

The present invention discloses a micro suction disk preparation method, which comprises: (1) coating a photoresist on a cleaned substrate, and drying; (2) preparing the outer hole pattern of the suction disk into a mask plate, and carrying out ultraviolet exposure on the mask plate and the photoresist on the substrate; (3) carrying out developing and blow-drying on the photoresist on the substrate to obtain a suction disk outer hole array; (4) preparing the inner hole pattern of the suction disk into a mask plate, and carrying out secondary ultraviolet exposure on the mask plate and the photoresist on the substrate; (5) carrying out secondary developing and blow-drying on the photoresist on the substrate to obtain a suction disk inner hole array; and (6) peeling the substrate to obtain the micro suction disk. According to the present invention, the micro suction disk is prepared by using the micro-manufacturing and the bionics principle and can form the foot of the climbing robot so as to achieve adsorption with any states under the effects of the mechanism and the micro-vacuum suction system; and the micro suction disk can be suitable for contacting in any states, and the adsorption effect can be improved by using the bristle adsorption mechanism.
Description
technical field [0001] The invention relates to a preparation method of a micro sucker and a special mold, which are mainly used in many fields such as micro manufacturing, micro mechanical system design, micro mechanics and the like. Background technique [0002] At present, there are many comparative studies on various robots applied to bionic geckos, and the research on the development of devices based on compound adhesion has also been vigorously developed. All these studies consider the interaction between gecko feet and planes mainly based on the principles of van der Waals' adhesion and adhesives. At the same time, different research teams at home and abroad have also obtained some preliminary results. But from a bionics point of view, why can't a dead gecko stick to a flat surface? Obviously, this issue needs to be reconsidered from the perspective of bionics. The inventors believe that the bristles on the surface of the gecko have microscopic sucker structures th...
