Grooving process of grooved rods for quartz long boats

Abstract

The invention discloses a grooved bar slotting process for a long quartz boat, comprising the following steps: A. making a quartz round bar into a square bar; B. cutting both ends of the square bar to check the flatness, length and verticality of the square bar C. Embed several square rods on the upper surface of the graphite plate with equal number of parallel "V"-shaped grooves, pour the connection between the square rods and the "V"-shaped grooves with liquid wax, and cool the liquid wax to solidify the liquid wax. Complete the fixing of the square bar; D. Put the graphite plate on which the square bar is fixed with wax on the table of the CNC machine tool; E. Adjust the angle of the blade axis of the CNC machine tool and install the blade; F. Call the program of the CNC machine tool to open the square bar Grooving; G. After the grooving is completed, the bar is waxed and cleaned. The invention has the advantages of good positioning and fixing effect of the quartz square bar, high slotting precision, less damage during slotting, easy removal of the bar after slotting, simultaneous slotting of multiple square bars, and high slotting efficiency.

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
