Problems solved by technology

At present, most suction cups need to be adsorbed on the surface of the substrate by extrusion. It is inevitable that the adsorption strength of the suction cup will be controlled by direct contact during use, which is not conducive to the use in the medical field, and once adsorbed, it cannot be easily removed.
[0003] In addition, some suction cups carry air pumps, through which the air in the suction cups is drawn to generate negative pressure, so that the suction cups are adsorbed on the surface of the substrate, and then the suction cups are desorbed through the deflation of the air pump. Higher sealing requirements

preparation example Construction

[0054] More specifically, the preparation method of the hard magnetic floppy disk comprises the following steps:

[0055] a) Take two-component silica gel and hard magnetic particles and mix them to obtain a mixed solution;

[0056] b) Pour the above mixed solution into a circular petri dish, then place the round petri dish in a vacuum drying oven, vacuumize it, and let it stand to obtain a hard magnetic floppy disk after curing;

[0057] c) Magnetizing the hard-magnetic floppy disk, applying a high-intensity parallel magnetic field along the thickness direction of the hard-magnetic floppy disk to obtain a magnetized hard-magnetic floppy disk.

[0058] Further, in step a), the mixing is stirring in a mixer, the stirring speed is 600-700rpm, and the stirring time is 5 minutes;

[0059] In step b), the vacuuming time is 5 to 20 minutes, and the standing time is 1 to 6 hours;

[0060] In step c), the intensity of the magnetic field is 1-2T, and the magnetization time is 5-10 mi...

Embodiment 1

[0072] Example 1 A method of using magnetically controlled chuck for adsorption

[0073] The magnetically controlled chuck comprises: a disc-shaped hard magnetic floppy disk, a cylindrical magnet (NdFeB permanent magnet), and a rope, wherein the hard magnetic floppy disk 1, the magnet piece, and the rope are coaxially arranged.

[0074] Specific adsorption methods include:

[0075] The magnet and the hard magnetic floppy disk are approached in the same way with the same magnetic poles, and the distance between the magnet and the hard magnetic floppy disk is adjusted to 22mm to control the adsorption strength of the hard magnetic floppy disk to the adsorbed substance, so as to realize the hard magnetic floppy disk for the adsorbed substance. adsorption;

[0076] When the hard magnetic floppy disk needs to be desorbed from the substance to be adsorbed, the rope is pulled to realize desorption.

Embodiment 2～8

[0078] Same as embodiment 1, the difference is that the distances between the magnet parts and the hard magnetic floppy disk are 20mm, 18mm, 16mm, 14mm, 12mm, 10mm, 8mm respectively.

Abstract

The invention provides a magnetically controlled chuck device and a using method thereof, which relate to the technical field of chucks. The magnetic control chuck device includes: a hard magnetic floppy disk, used to absorb the substance to be adsorbed; a magnet piece, used to provide a magnetic field effect for the hard magnetic floppy disk, and the magnet piece and the substance to be adsorbed are respectively located on both sides of the hard magnetic floppy disk; , for pulling hard magnetic floppy disks. The magnetically controlled sucker device can be used in the field of medical equipment, and has a simple structure, novel design, controllable adsorption strength, low maintenance cost, safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of chucks, in particular to a magnetically controlled chuck device and a method for using the same. Background technique [0002] A suction cup is a tool that uses the pressure difference between the inside and outside of the atmosphere to absorb or grab objects. At present, most suction cups need to be adsorbed on the surface of the substrate by extrusion. It is inevitable that the suction strength of the suction cup will be controlled by direct contact during use, which is not conducive to the use in the medical field, and once adsorbed, it cannot be easily removed. [0003] In addition, some suction cups carry air pumps, through which the air in the suction cups is drawn to generate negative pressure, so that the suction cups are adsorbed on the surface of the substrate, and then the suction cups are desorbed through the deflation of the air pump. Higher sealing requirements. Contents of the invention ...
