Abstract

The invention discloses a hanging fixture for micro magnet electrophoresis and a use method of the hanging fixture. The micro magnet electrophoresis hanging fixture is used for hanging micro magnets (3) with the inner hole diameter smaller than 1mm for electrophoresis and comprises at least one hanging layer; each hanging layer is composed of an outer framework (1) and at least one placing bar (2); two ends of the placing bar (2) are respectively arranged on the outer framework (1); each placing bar (2) is arranged inside the outer framework (1) in parallel; the placing bar (2) is of a spring shape; each micro magnet (3) is respectively hung on the placing bar (2); and adjacent micro magnets (3) are isolated by a spiral. The hanging fixture provided by the invention has advantages as follows: the placing bar for the electrophoresis is made of a stainless steel wire with the diameter about 0.3mm and is wound to form a spiral shape; cathode electrophoresis of the micro magnet with the inner hole diameter smaller than 1mm can be realized; antioxidant and anticorrosive properties of the micro magnets are guaranteed; and besides, the micro magnets are not sticky to one another in an electrophoresis process; and the electrophoresis operation is simple. and the effect is good.

Description

A kind of tiny magnets electrophoresis hanger and method of use thereof

Technical field

The present invention relates to a kind of tiny magnets electrophoresis hanger and method of use thereof.

Background technology

Neodymium iron boron binding magnet because of its magnetic good uniformity, freedom shape is big, dimensional precision is high, meets the developing direction of hyundai electronics components and parts " light, thin, short, little ", is described as " pacemaker " of 21 century information industry.Yet, because the chemical property of neodymium iron boron is extremely active, in malaria, be easy to oxidizedly, and also very easily be corroded with acid generation strong reaction.

The antirust treatment technology of neodymium iron boron binding magnet ability cathode electrophoresis has solved the matter of great urgency of neodymium iron boron binding magnet producer; Widened the Application Areas of neodymium iron boron binding magnet; Improve the product quality and the output of magnet generation producer, directly improved the economic benefit of producer; And, for material surface protection engineering science the case of research mechanism is provided also, the protection against corrosion research of other analogous materials there is reference function.

Along with design of electronic products with make constantly to the microminiaturization development, the required magnet size of a lot of micromachines is more and more littler, requires increasingly high.When magnet internal diameter very little (diameter of bore is less than 1mm); Some traditional electrophoretic painting hangers are no longer suitable, have no alternative but to change the application mode into, like paint spraying etc.; But because the magnet internal diameter is very little; Paint also can not apply up often effectively, causes the resistance of oxidation of magnet to descend, and Corrosion Protection does not reach requirement of client.

Summary of the invention

The objective of the invention is to solve the deficiency of prior art; Providing a kind of electrophoresis to put bar turns to spiral helicine by thin Stainless Steel Wire; Can realize the ability cathode electrophoresis of tiny magnets, ensure that tiny magnets is anti-oxidant, the tiny magnets electrophoresis hanger and the method for use thereof of corrosion resistance.

The objective of the invention is to realize: a kind of tiny magnets electrophoresis hanger through following technical scheme; Be used to mount diameter of bore and carry out electrophoresis less than the tiny magnets of 1mm; It comprises that at least one mounts layer; Each mounts layer and is put bar and constituted by outside framework and at least one, and the two ends of putting bar are installed in respectively on the outside framework, respectively put bar and are set in parallel in the outside framework; The described bar of putting is spring-like, and each tiny magnets is mounted on respectively puts on the bar, separates through spiral between the adjacent tiny magnets.

The bar of putting of the present invention is that the Stainless Steel Wire coiling of 0.3mm forms by diameter.

Of the present invention mounting also is provided with at least one supporting traverse on the layer, supporting traverse is supported on the below of putting bar, and its two ends are fixedly mounted on the outside framework.

Of the present invention mounting between the layer links to each other through union lever.

A kind of method of use of tiny magnets electrophoresis hanger, it may further comprise the steps:

S1: an end of spring-like being put bar is fixedly mounted on the outside framework, treats that electrophoretic tiny magnets is enclosed within through the other end string of putting bar respectively to put on the bar, separates through spiral between the adjacent tiny magnets, does not contact mutually;

S2: after putting on the bar string and having overlapped the tiny magnets of specified quantity, the end in order to string cover tiny magnets also is fixed on the outside framework on the bar with putting;

S3: repeating step S1～S2, until respectively putting the tiny magnets that has all mounted specified quantity on the bar, and the two ends of respectively putting bar all are fixedly mounted on the outside framework;

S4: whole electrophoresis hanger is immersed in the tiselius apparatus, tiny magnets is carried out electrophoresis.

The invention has the beneficial effects as follows: electrophoresis is put bar and is turned to spirrillum by the Stainless Steel Wire of the about 0.3mm of diameter, can realize the ability cathode electrophoresis of diameter of bore less than the tiny magnets of 1mm, has ensured anti-oxidant, the corrosion resistance nature of tiny magnets; And, in the electrophoresis process, not sticking together between the tiny magnets, electrophoresis is simple to operate, respond well; In addition, this electrophoresis hanger also has making processes and simply reaches characteristics such as cost of manufacture is low.
