Diamond machining equipment

Abstract

The invention relates to the technical field of diamonds, in particular to diamond machining equipment which includes a vapor deposition furnace and a hot wire mechanism arranged in the vapor deposition furnace, wherein the hot wire mechanism includes a bearing frame and a plurality of hot wires arranged on the bearing frame; the bearing frame includes a first mounting beam and a second mounting beam which are arranged in parallel, the first mounting beam is provided with a plurality of clamps around which the hot wires are wound, wherein the clamps are slidably mounted on the first mounting beam in a direction perpendicular to the length direction of the first mounting beam; an elastic element is arranged between the first mounting beam and each of the clamps, and the clamps always keep a trend of sliding towards the outer side of the first mounting beam through the elastic element; and the hot wire mechanism further includes a detection element arranged on the first mounting beam or the clamps, and when the elastic element restores to an initial position, the detection element is triggered to feed back signals to a control center. According to the invention, a reminding effect can be achieved when the hot wires are fused.

Description

technical field [0001] The present invention relates to the field of diamond technology, in particular, to a diamond processing equipment. Background technique [0002] The diamond film is mainly prepared by vapor deposition in a vapor deposition furnace. The main principle is that the mixed gas composed of carbon source and hydrogen passes through the metal hot wire, and methyl and hydrogen atoms are decomposed in the high temperature field formed by the hot wire, and, Under a certain pressure in the cavity, a large number of methyl groups interact with the substrate surface at a suitable temperature and the recombination reaction between the methyl groups makes hybrid hydrocarbon groups generated in the high temperature field, and these hydrocarbon groups are on the substrate. surface deposition to form a diamond film on the substrate surface. [0003] However, in the existing vapor deposition furnaces, the hot wires are generally arranged therein, and during operation, t...

Problems solved by technology

[0003] However, in the existing vapor deposition furnaces, the hot wires are generally arranged therein, and during operation, the entire vapor deposition furnace is in a closed state. At this time, if one or several hot wires are fused, it is difficult to be found. If you continue to process and manufacture, because the hot wire is fused, the temperature at the place will be affected, which will affect the quality of the final diamond film, so it needs to be improved.
