Problems solved by technology

[0008] The technical problem to be solved by the present invention is: the tip of the carbon rod used for vapor deposition in the prior art wears quickly, and the size of the tip of the carbon rod is not easy to control, so that the thickness of the carbon film produced by spraying is not uniform, and the spraying efficiency is reduced. Low, not conducive to the development of batch sample spraying work

Abstract

The invention provides a carbon rod cutting device and a film coating instrument evaporation assembly provided with the same. The carbon rod cutting device comprises a carbon rod propelling portion, acarbon rod cutting portion, a carbon rod containing portion and an electric control portion. The carbon rod propelling portion comprises an elastic component, a fixed end and a movable end, wherein the fixed end is provided with a first through hole, and the movable end is provided with a second through hole. The two ends of the elastic component are connected with the fixed end and the movable end. After penetrating the first through hole and the second through hole, the output end of each carbon rod synchronously moves together with the movable end. The carbon rod cutting portion comprisesan inlet limiting component, a tool and an outlet limiting component. The tool is arranged to be used for receiving the carbon rods moved by the carbon rod propelling portion, cutting the output endsof the carbon rods and only allowing parts of the cut carbon rods with the diameters being within the preset range to pass through. In this way, the sizes of the sharp ends of the output ends of the carbon rods for evaporation can be effectively controlled; the sizes can be uniform and meet the spraying requirement all the time; and thus, the good foundation is laid for achieving continuous multi-batch spraying operation.

Description

technical field [0001] The invention relates to the technical field of mineral testing, in particular to a carbon rod cutting device and an evaporation assembly of a coating instrument with the carbon rod cutting device. Background technique [0002] At present, most of the samples tested by electronic probes are non-conductive rock and mineral samples. Before the sample analysis and testing, it is generally necessary to coat the thin slice samples of the electronic probe to prevent the discharge phenomenon on the surface of the samples. In actual operation, due to the disadvantages of high cost and strong signal absorption of the gold film, most samples are conductively treated by evaporative carbon plating. However, due to the influence of the vacuum requirements of the spraying environment and the diffusion range of carbon vapor, the efficiency of spraying is low. Generally, a complete coating process takes about 3-4 hours. [0003] Through the analysis of the carbon spr...
