Description

A kind of automatic grinding device of metallic film sample

Technical field

The utility model relates to a kind of preparation facilities of sample, and particularly a kind of automatic grinding device of metallic film sample, this device and Ginding process are applicable to the grinding and the polishing of sheet metal sample too.

Background technology

Transmission electron microscope sees through the thin district of sample through high-velocity electrons and penetrates imaging; Material is very strong to the scattering of electronics; The penetration depth of electronics in material is limited; As the sample required thickness of transmission electron microscope observing at 500 dust to 2000 dusts, cleaning surfaces, it is big and unmannedly be the thin district of defective (electron beam clear area) to have an area.The success or not that film sample is made is directly connected to the observations of transmission electron microscope.Make the attenuate that desirable transmission electron microscope sample will pass through multiple working procedure, wherein machinery in advance attenuate be the step of the most basic most critical of sample preparation.It requires sample is ground to about 30 μ m from about 0.5mm.

Machinery at present commonly used thining method in advance is that thin slice with well cutting sticks with glue on derby or rubber, and hand-held derby or rubber grind on sand paper.Dynamics size and the center of effort that grinds sample is by on hand dynamics with the force decision.Because sample is very thin, artificial firmly inequality can directly cause the sample mill partially, makes the sample uneven distribution, and the interfere with layer that sample produces is also uneven, and next step attenuate is impacted.Mainly there are two problems in method fixing sample with pasting, and the first, difficulty is installed and taken off to sample.To wait several hours during the sample installed or even could cement sample in 20 hours.Need peptization be separated with organic solvent when taking off sample, specimen surface has residual glue, the cleaning difficulty.The second, because the lay time is long, sample can't take off sample measurement thickness at any time in process of lapping, so thickness is difficult to control.If take off sample after grinding, measure sample thickness and do not reach requirement, also need paste sample again, will make the sample preparation time lengthening.

The preparatory thining method of the machinery of transmission electron microscope metallic film sample all can't be avoided artificial factor at present, can not reach the requirement of making desirable film sample.

The utility model content

The purpose of the utility model is for making transmission electron microscope metallic film sample a kind of automatic grinding device to be provided, and this device loading and unloading sample is convenient, fast, and ability automatic grinding sample can be eliminated human factor influence to the sample preparation effect in the mechanical reduction process.

The purpose of the utility model is achieved in that it comprises: objective table and lapping device, objective table comprise base, slideway, slide block, pillar; The objective table below is a base, and base and slideway connect as one, and slide block is connected in the slideway, is equipped with pillar on the slide block, and lapping device comprises abrading block and connecting rod, and abrading block and connecting rod are fixed, and connecting rod is enclosed within on the pillar at two ends, and motor is connected on the slideway of a side.

The concrete structure of the utility model has, and wearing layer is housed on the base, is fixed by register pin; The centre bit of base and wearing layer is equipped with a pair of groove of answering, built-in sample slipmat, and sample is placed on the slipmat; Slipmat and wearing layer have the difference in height of 30 μ m, can prevent that sample from skidding off slipmat.

The structure of the utility model also has, and sand paper sticks on the abrading block bottom, and there is cavity at the abrading block center, and counterweight is housed in the cavity, and counterweight weight can be changed as required.

The both sides cylindrical sleeve of the utility model connecting rod and pillar wringing fit, cylindrical sleeve drive abrading block and can slide up and down along pillar, in order to put, to materials and to adjust the distance of abrading block and sample.

The utility model adopts the motor-driven slide block, on slideway, moves, thereby makes pillar drive the abrading block to-and-fro movement, realizes the grinding to sample.

The advantage and the effect of the utility model are:

1, the weight of abrading block and counterweight can apply downward grinding pressure to sample, compares uniform force application with former hand-ground, and sample can not grind partially, and the sample preparation success ratio is high.2, slide block to-and-fro movement under the driving of motor drives the abrading block to-and-fro movement and grinds sample, and easy to operate, sample preparation efficient is high, compare with former manual polishing save time, laborsaving.3, abrading block and connecting rod link together, and can move up and down along pillar, and only with hand is mentioned abrading block and just can sample be taken out, and sample is easy to loading and unloading, can take off the sample measurement sample thickness at any time.4, the utility model does not have interference from human factor in the grind away process, sample preparation conditional stability, the repeatable height of sample preparation effect.
