  • Patent number: 11478976
    Abstract: A flat-pressing manufacturing method of a bionic adhesive structure based on a micro through-hole nickel-based mold is disclosed. The method includes the following steps: preparing a nickel-based mold with a micro through-hole array; placing the nickel-based mold on an elastic pad in a magnetic mold closing system; coating a liquid prepolymer uniformly on a backing, and placing a side of the backing coated with the liquid prepolymer on the nickel-based mold, covering a sealing diaphragm on the backing to separate a cavity into an upper chamber and a lower chamber, and performing a vacuum treatment on the lower chamber and an inflation treatment on the upper chamber to apply a uniform pressure on the backing layer and achieve a full filling of prepolymers with different viscosities; and after the filling is completed, curing and demolding to obtain the bionic adhesive structure.

  • Patent number: 11254566
    Abstract: A preparation method of a bionic adhesive material with a tip-expanded microstructural array includes the following steps: machining through-holes on a metal sheet; modifying morphology of a through-hole by electroplating, using the metal sheet in step 1 as an electroplating cathode, and arranging the electroplating cathode and an electroplating anode in parallel to prepare a hyperboloid-like through-hole array assembly, fitting a lower surface of the hyperboloid-like through-hole array assembly tightly to an upper surface of a substrate assembly to prepare a through-hole assembly of a mold; and filling the mold assembly with a polymer, curing, and demolding to obtain the adhesive material with the tip-expanded microstructural array.

  • Patent number: 10401245
    Abstract: A novel six-dimensional force and torque sensor includes a central boss, a cylindrical housing arranged outside the central boss, and twelve elastic beams for connecting the central boss with the cylindrical housing. The twelve elastic beams are respectively provided with strain gauges as needed, and a bottom of the central boss is provided with a mounting hole for mounting a signal processing module. The present invention has the characteristics of self-decoupling, high rigidity, high natural frequency, desirable linearity, ideal repeatability and perfect hysteresis, and ability to measure a large torque (50 N·m). In addition, the sensor can be designed to have different measuring ranges and sensitivities by changing the dimensions of each of the elastic beams.
