Problems solved by technology

However, the controllable external magnetic field is generally a manipulator holding a permanent magnet to move the magnetic field or a Helmholtz coil to generate a changing magnetic field. The magnetic field strength generated by the permanent magnet cannot be adjusted and the operation is complicated. Multiple Helmholtz coils can generate changing magnetic fields. Low utilization rate of magnetic field space and high cost

Embodiment Construction

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like figure 1 As shown, a four-electromagnetic coil magnetron magnetic droplet testing device includes a base, a test table 18 and a two-dimensional magnetron driving device mounted on the base. The height of the table top of the test bench can be adjusted. Specifically, the test table 18 includes a base, a column, a clamping block and a platen. Vertically arranged uprights are fixed on the base. The clamping block is provided with a connecting hole. The clamping block is slidably connected with the upright column through the connecting hole. The side part of the connection hole is provided with a locking seam. The locking seam separates two locking parts on the clamping block. The two locking parts are connected by locking bolts. By turning the locking bolt, the connecting hole can be clamped to the upright column, so that the platen and the test bench are...

Abstract

The invention discloses a four-electromagnetic coil magnetic control type magnetic liquid drop testing device. The invention includes a base, a test bench and a two-dimensional magnetic control driving device installed on the base. The two-dimensional magnetic control driving device is arranged directly under the platen of the test bench. The two-dimensional magnetically controlled driving device includes a two-axis slide table, two arc-shaped guide rails, two pairs of arc-shaped sliders and two pairs of electromagnetic coils. The guide rail bracket is installed on the two-axis slide table. The electromagnetic coil in the present invention can slide along the arc-shaped guide rail and can rotate itself, so that a variety of magnetic fields with different distribution forms can be formed on the test platform, so that the performance of the magnetic droplet can be fully tested. The present invention uses four electromagnetic coils to generate a vertically upward magnetic field in the working space, and the field strength is adjustable, so that the driven magnetic liquid droplet (micro robot) can float and generate a magnetic field along with the movement of the two-axis slide response.

Description

technical field [0001] The invention belongs to the technical field of magnetron micro-robot drive, in particular to electromagnetic coil magnetic field drive, and the main function is to generate vertical upward force through multiple sets of electromagnetic coils to suspend a magnetic micro-robot above the electromagnetic coils, and to adjust the position of the electromagnetic coil group. , which can realize the cableless motion of the two-dimensional plane of the micro-robot. Background technique [0002] Life activities and production technologies are inseparable from the control of liquids. Regulating the directional transport of droplets has important scientific research significance and extensive engineering application value in microfluidics, evaporative heat transfer, biomedicine, and water collection. Inspired by natural organisms such as cactus thorns for directional collection of water, the lip of Nepenthes pitcher to spontaneously form a lubricating layer, and ...
