Groove rod grooving process of quartz long boat

Abstract

The invention discloses a groove rod grooving process of a quartz long boat. The process comprises the following steps that A, a quartz round rod is prepared into a square rod; B, the two ends of thesquare rod are cut, and the flatness, the length and the perpendicularity of the square rod are detected; C, and the multiple square rods are embedded into the upper surface of a graphite plate with the equal number of parallel V-shaped grooves, liquid wax is poured at the joints between the square rods and the V-shaped grooves, the liquid wax is solidified through water cooling, and the square rods are fixed; D, the graphite plate of the square rods fixed by the liquid wax is placed on the table surface of a numerical control machine tool; E, the angle of a blade shaft of the numerical control machine tool is adjusted, and a blade is installed; F, the square rods of the numerical control machine tool is called to carry out grooving processing; and G, conducting wax formation and cleaningare performed on the square rods after grooving is completed. The groove rod grooving process has the advantages that the positioning and fixing effect of the quartz square rods is good, the groovingprecision is high, the quartz square rods are not easy to damage in the grooving process, the multiple square rods can be opened at the same time, and the grooving efficiency is high.

Description

technical field [0001] The invention relates to the technical field of grooving processing of quartz grooved rods, in particular to a grooved rod grooving process for quartz long boats. Background technique [0002] Quartz boat is an essential tool for diffusion process. Whether it is the diffusion of semiconductor devices or the diffusion of solar energy technology, a large number of quartz devices are used as carriers. Quartz boats are resistant to high temperatures without deformation, do not pollute devices and can be reused, especially in recent Due to the rapid development of the solar energy industry in recent years, people use more and more styles of quartz boats, which play a huge role in the photovoltaic industry. In terms of structure, the quartz boat is composed of multiple grooved quartz square rods and a pair of quartz sides. The boat-like carrier formed by the combination of the cover can insert multiple solar cells into the slot for diffusion processing. Ther...

Problems solved by technology

[0003] Especially for quartz longboats, the length of the square rod is long. How to position and fix the square rod during slotting is a difficult point, which will directly affect the quality and accuracy of the square rod after slotting. At present, the square rod is Before the groove is processed, it is generally directly fixed on the worktable of the CNC machine tool with a 90° V-shaped groove. After the square rod is embedded in the V-shaped groove, stoppers are inserted at both ends of the V-shaped groove to prevent the square rod from moving left and right. In the actual processing process, it is found that, This fixing method causes the square rod to vibrate slightly up and down during the cutting process, which may make the slotting position uneven, or cause the square rod to break as a whole; in order to reduce the temperature at the cutting place during the slotting process, it is necessary to constantly Spray coolant to the cutting position. The main component of coolant is water. After the square bar is grooved, it is in a humid environment. The force between the water molecules will make the 90° V-shaped groove and the square bar embedded The two sides are tightly combined, too many hydrogen bonds are assembled, resulting in strong binding force, and it is difficult to take out the square rod directly
