Problems solved by technology

In the Chinese patent "Preparation and use method of a micron-scale magnetic tweezers" (CN111508706A), a magnetic field was used to deform the two microcolumns to achieve the effect of tweezers. However, in the above patent, the two microcolumns of the microtweezers are in Under the same magnetic field, the deformation can only occur in the same direction, and the micropillars cannot deform in different directions under the same magnetic field, which greatly limits the scope of application of microtweezers, and also limits this idea to only two tweezers

Embodiment 1

[0044] like Figure 1-5 and Figure 8-9 As shown, the method for preparing and using a micron-level microscopic intelligent robot in this embodiment includes the following steps:

[0045] Step 1: Fill the particles (the non-magnetic substance SiO 2 Encapsulated magnetic particles Fe 2 O 3 ) of the nanocomposite resin Bis-GMA / TEGDMA (filling particle mass fraction of 15%) was dropped onto the silicon template substrate (the diameter of the substrate cavity was 5 μm), and the resin was infiltrated into the column cavity of the silicon template substrate through a vacuum-assisted molding process. to form product I;

[0046] Step 2: Place two parallel magnets on the product I along the direction of the vector (-1, -1, -1), and two parallel magnets are placed at equal distances from both ends, so that the product I is subjected to the direction of the vector (-1, -1, -1). magnetic field, so that the magnetic particles are oriented along the current magnetic field direction in ...

Embodiment 2

[0061] Example 2 has the same steps as Example 1, except that: in step 1, the mass fraction of magnetic particles in the mixed solution is 10-30%.

Embodiment 3

[0063] The steps of embodiment 3 are identical with those of embodiment 1, and the difference is: in step 1, the magnetic particles are Fe, Fe 2 O 3 , Fe 3 O 4 , one or more of Co and Ni.

Abstract

The invention discloses a preparation and use method of a microscopic intelligent robot and a microscopic magnetic gripper. Drop the particle-filled composite resin onto a template with a micron-scale column cavity to allow the resin to penetrate into the column cavity of the template; apply a magnetic field from the origin of the spatial coordinate to any direction in the seventh quadrant to illuminate the resin outside the photomask Make it solidify; then rotate the magnetic field clockwise around the z-axis by 90°, 180°, and 270°, respectively, after each rotation, illuminate the resin outside the photomask to solidify it; cover the PET substrate on the resin, and the substrate and the After the resin is combined, it is peeled off from the template to obtain a microscopic intelligent robot; the microscopic intelligent robot made by the present invention can achieve different deformations in the four micro-columns by applying different magnetic fields, thereby generating horizontal movement, turning, and grasping the micro-particles. Movements such as take and release.

Description

technical field [0001] The invention relates to the technical field of preparation of functional composite materials, in particular to a preparation and use method of a microscopic intelligent robot and a microscopic magnetic gripper. Background technique [0002] Robot technology is a rapidly developing high-tech, which has been widely used in many fields and has an increasingly significant impact on human society. [0003] Micro robot refers to a small mobile mechanism that integrates tiny work tools and has general programming capabilities. Micro-robots are small in size, precise in devices, and can perform micro operations. They have the characteristics of small inertia, fast response, high resonant frequency, and high added value. However, micro-robots are not the miniaturization of ordinary robots in a simple sense. Micro-robots generally integrate sensing, control and execution units, and are the cross-integration of multi-disciplinary technologies such as mechanics,...
