The processing structure can fix the slice-shaped precious metal target conveniently and rapidly and causes no scratch and extrusion deformation to precious metal. The processing structure can serve as a high-precision processing device used for conventional machining. The processing structure is easy to use and low in cost, is made of material that can be purchased conveniently, requires no special fixtures, can be employed universally and can save a large amount of cost and time spent in precious metal processing.
Description
Technical field
The utility model belongs to target body processing unit (plant) scope, particularly a kind of processing structure of sheet type noble metal target in thin-film technique.
Technical field
Along with the development of science and technology, thin-film technique obtains a wide range of applications as making electronic device method commonly used, in semiconductor technology, and solar energy, magnetic recording, liquid crystal display, the high-tech areas such as optics and decoration have obtained large-scale application.And the target that is used for the making film has also obtained significant progress.Wherein the application of noble metal target material is very general.The noble metal cost is high, and processing loss is large, and metal is soft, reach comparatively difficulty of accurate size, and the target that the user often requires to make is thin type structure, the cost that takies to reduce it.The quantity that feeds intake that any one noble metal processing factory commercial city is thought to reduce as much as possible noble metal is to the shared fund cost of minimizing noble metal, but the deficiency that feeds intake is difficult to the output finished product.Will avoid as much as possible simultaneously loss in process in this, noble metal is softer, and for thinner workpiece, the clamping distortion often is difficult to avoid, and this often makes workpiece scrap; If the material that the method that employing is adhesively fixed can be selected is a lot.Reliable method commonly used is the indium weldering, is about to noble metal and retain support plate in welding more than the fusing point of indium, and then carries out machined.Can fix preferably foil and gripper shoe although adopt the method for brazing metal, but the noble metal wellability is good, scolder be easy to and noble metal between spread, thereby thin slice is easy to occur alloying pollutes noble metal target material, and be difficult to break away to fall scolder, even removed scolder, scolder easily scratches solder side
For the noble metal processing of traditional jewellery industry, Au, Ag, Pt, the production of Pd or its alloy adopts the mode of handwork to carry out machining mostly, for making length and width at 100-400mm, the processing of the noble metal of the sheet type of thickness 1-10mm, efficient is very low, and precision also almost is difficult to reach the needed requirement of present industry.And for the car that adopts present technique, mill, plane, pincers, often there is larger mechanical grip power in the techniques such as mill, as patent CN200620148447.4.Slim workpiece is easily distortion usually, the soft pure noble metal of matter especially, common clamping certainly distort, and residual adding hold vestige, for the high accuracy target, can not reach instructions for use.Modern mechanical processing often comes the workpiece of handling ease distortion by making special mold or fixture.This need to shift to an earlier date is be installed mold or the mould of the workpiece designing and making precision of given shape specially, takes time and effort, and cost is high, and is long in time limit.
The utility model content
The purpose of this utility model is softer for noble metal in prior art, for thinner workpiece, the clamping distortion often is difficult to avoid, the deficiency that workpiece is scrapped, and a kind of processing structure of sheet type noble metal target is proposed, it is characterized in that, apply one deck bonding agent 2 between target 1 and gripper shoe 3.
Described target is the simple substance noble metal target material, and the target size is at 100-400mm.Thickness is between 1-5mm, and Hv is at 5-30.
Described target is Au, Ag, Pt, Pd or its alloy
Described gripper shoe is for adopting iron plate or nickel plate etc. that the gripper shoe of good soft magnet performance is arranged, and its flatness is between 0.05-0.5, and surface smoothness is at 3.2-0.8um, and the length of side is 100-400mm, and thickness is 8-30mm.
Described bonding agent is 502 glue,
The beneficial effects of the utility model are that the material of the processing structure that adopts is common material, take conveniently, and cost is low.Common iron plate is in order to the support slice noble metal, can clamping iron plate when machined in order to fixing.When the grinding operation, fix noble metal target material it processed thereby can hold with the electromagnet of grinding machine iron plate, can be conveniently fixing sheet type noble metal target material, can any scuffing, crimp not arranged to noble metal in process.
Description of drawings
Fig. 1 is the processing structure schematic diagram of sheet type noble metal target.
The specific embodiment
The utility model proposes a kind of processing structure of sheet type noble metal target.Below in conjunction with drawings and Examples, the utility model is further described.
In the processing structure schematic diagram of sheet type noble metal target shown in Figure 1, apply one deck bonding agent 2 between target 1 and gripper shoe 3; This bonding agent adopts 502 glue; Because 502 glue are take ECA as main, add tackifier, stabilizing agent, flexibilizer, polymerization inhibitor etc., the one-component instantaneous solidification adhesive that synthesizes by vanguard technology.Its water white transparency good fluidity, nontoxic, non-combustible, volatile, meeting water is polymerizing curable.Curing rate is fast, easy to use, bonding force is strong, adhesives is extensive, can be used for iron and steel, non-ferrous metal, rubber, leather, plastics, pottery, glass, timber etc., be widely used in the industries such as electrical equipment, instrument, machinery, electronics, light instrument, medical treatment, light industry is civilian.Its adhesive shear strength can reach 20-30Mp, can satisfy the requirement of non-violent machining fully.Binder 502 glue be used for bonding noble metal and iron plate simple to operate, convenient, intensity can satisfy the requirement of processing.When complete bonding after, gripper shoe can be clamped and carry out line cutting, Vehicle Processing, the machining that grinding etc. are common owing to never touching the noble metal thin plate, therefore can not scratch precious metal surface, can be with its clamping distortion yet.
After machining, noble metal target material and gripper shoe are heated to 120-150 ℃ together, or it is immersed in acetone or isopropyl alcohol ultrasonic 3-10 minute, target and gripper shoe are also tear-away.502 glue be a kind of be a kind of instant glue, as long as with the dissolving organic solvent just can, can fast glue be dissolved in wherein with acetone or isopropyl alcohol, the target material surface that obtains like this is bright and clean, and is pollution-free, size is accurate; This processing structure is pollution-free to target, target is not damaged the threat of distortion, can save Precious Metals Resources.
Embodiment
1. preprepared magnetic conduction is good, and flatness is between 0.05-0.5, and surface smoothness is at 3.2-0.8um, and the length of side is 100-400mm, and thickness is that the gripper shoe of 8-30mm and size are at 100-400mm.The noble metal thin slice target of thickness between 1-5mm will both clean up, and 502 glue are spread in symmetrical evenly being coated with on gripper shoe, immediately the noble metal thin slice are pressed on gripper shoe with 2-10Mpa pressure, keep 2-5min to get final product.
2. retain support plate, carry out machined to noble metal.
3. completion of processing, noble metal target material and gripper shoe are heated to 120-150 ℃ together, or it is immersed in acetone or isopropyl alcohol ultrasonic 3-10 minute, target and gripper shoe are also tear-away, can totally remove thoroughly 502 glue with acetone or isopropyl alcohol solder side; Pollution-free to target, target is not damaged the threat of distortion.
