Description
Technical field
The utility model relates to a kind of naked diamond fret saw production system, relates in particular to a kind of upper sand device for naked diamond fret saw production system.
Background technology
Electronics, new forms of energy and the fast development of optics industry, by monocrystalline silicon, sapphire, magnetic material, ceramic material, jade, the manufacturer that the materials such as noble metal cut into wafer constantly increases.Main flow multi-line cutting process on market is " naked steel wire+abrasive water ".The cutting mode of this employing free abrasive and inner circle saw blade in the past, cylindrical blade, band saw is compared, and has and can cut major diameter crystal bar and multi-thread cutting simultaneously, reduces the advantages such as line loss, but also exists following obviously not enough:
1, crystal bar and machining area fat base lapping liquid pollute;
2, slimy cutting fluid needs, through processing discharge, easily to cause environmental pollution after use, then in processing procedure, water discharge is very large, and environmental protection pressure is large.
3, the Material Removal Mechanism that cutting technique is free abrasive, stock-removing efficiency is low;
4, sapphire, GaAs, carborundum etc. second, three generations's semi-conducting material hardness are high, are difficult to cutting, and wafer surface roughness is high.
5, waste material is close with abrasive grain later in cutting, is difficult to recycling.
Diamond fret saw cutting technique, cutting speed is " naked steel wire+abrasive water " 3-5 times.In the time of cutting same material, the former only has the latter's 1% by needed abrasive particle line.Since use instead emulsified water cooling after, the wastewater flow rate of producing equal number product reduce in the past 2%, meet advocating that national energy-saving reduces discharging.
Electroplating diamond fret saw is that the diadust of high rigidity, high-wearing feature is cemented on wire.Apply to crystal-cut, cutting speed is fast, and wastewater flow rate is few, and wafer bending degree, angularity are little, and the depth of parallelism is good, and gross thickness tolerance discrete type is little, and edge of a knife cutting loss is little, and surface damage layer is shallow, and wafer surface roughness is little.Cut material covers various semi-conducting materials, as silicon, germanium, lithium tantalate, and GaAs, indium phosphide, the precision cutting of the materials such as synthetic cut stone, carborundum and quartz glass, alumina wafer.
The production system of producing at present electroplating diamond fret saw mainly has the following disadvantages:
1, current diamond electroplating diamond fret saw all adopts plating clothing diadust, uses and electroplates or chemical plating on diadust surface, and the modes such as Composite Coatings are first plated layer of metal, make micro mist surface conductance, then come into operation.Can make in this way diamond quick adsorption surface online, simultaneously because diamond surface has electric conductivity, in electrodeposition process, due to point effect, can make the coating of diamond surface become very thick, thickness of coating is greater than the thickness of coating on bare wire surface, affects the cutting power of line.
2, plating clothing diamond deposition is in bare wire surface, and itself,, due to the problem of conduction, is easy to plated with gold hard rock again, makes surface produce the phenomenon of reuniting or piling up, and affects cut quality.
3, the diamond wire production equipment of existing application is generally all single cabling, and production efficiency is lower.
Therefore seek that a kind of product cutting power is high, diamond dust plating evenly and can to realize the naked diamond fret saw production system that rapid batch produces particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of, diamond dust plating high for completed knocked down products cutting power evenly and can realize the upper sand device of the naked diamond fret saw production system that rapid batch produces.
The purpose of this utility model is achieved in that
Sand device in one, comprise upper sand launder in it, described upper sand launder comprises up and down on the upper strata of arranging sand launder in sand launder and lower floor, on upper strata, in sand launder and lower floor, the middle part of sand launder is provided with ring-shaped sand road, in lower floor, the leading portion of sand launder and back segment top are provided with sand guide roller, two upper sand pinch rollers arranging before and after top, Sha road, right side, ring-shaped sand road is provided with, the lower edge of upper sand pinch roller is positioned at ring-shaped sand road, two groups of transmission devices arranging before and after ring-shaped sand road comprises and transmission abrasive band, diamond dust is arranged in the transmission abrasive band in ring-shaped sand road, sand liquid is set in sand launder in sand launder and lower floor on upper strata, the liquid level of upper sand liquid is higher than the sand face of the diamond dust on transmission abrasive band.
Transmission device comprises driving gear, travelling gear and the supporting plate of coaxial connection, and the two ends in transmission abrasive band are set up on supporting plate, and the inner edge in transmission abrasive band engages with the outer rim of travelling gear.
The below of described upper sand launder is provided with sand liquid collecting tank.
Supporting plate is circular slab.
Compared with prior art, the beneficial effects of the utility model are:
1, diamond dust is naked diamond, in cutting process, need not put the first edge on a knife or a pair of scissors, and cutting power is strong.
2, naked diamond is non-conductive, there is no the phenomenon of accumulation, seldom reunites.
3, native system can be realized the cabling production simultaneously of many bare wires, enhances productivity, and realize rapid batch and produce, and the scroll saw of naked diamond production, finished product wire diameter, than the little 10-20 micron of conventional production wire diameter, reduces line loss, good in economic efficiency.
Therefore on the utility model, sand device has advantages of that product cutting power is high, diamond dust plating even and can realize rapid batch and produce for assembling naked diamond fret saw production system.
