Description

Technical Field

[0001] The utility model relates to the technical field of round seed crystals, in particular to a round seed crystal processing device. Background Art

[0002] Seed crystal is a small crystal with the same crystal orientation as the desired product. It is the seed for growing single crystal. Using seed crystals with different crystal orientations as seeds will obtain single crystals with different crystal orientations. Round seed crystal is a type of seed crystal. Seed crystal silicon carbide is a commonly used material for seed crystals. It has attracted widespread attention due to its excellent semi-insulating properties. Silicon carbide needs an annular barrier band at the surface processing during processing.

However, in actual use, the carving knife is easily damaged on the surface of the round seed crystal due to its fixed height and angle, affecting the processing quality of the round seed crystal. In addition, the sliding rail cannot flexibly adjust the processing position of the round seed crystal, affecting actual use. Utility Model Content

[0019] The outer side of the driven gear 5 is meshed with the driving gear 9, the output end of the motor 8 extends to the bottom of the support plate 3 and is welded and fixed to the driving gear 9, a slide groove is provided on the top of the moving block 10, and the moving block 10 is slidably connected to the outer side of the slide rail 7 through the slide groove, and the moving block 10 can be moved through the slide rail 7, so as to move the horizontal position of the engraving knife 20 and expand the processing area of ​​the engraving knife 20. The driving gear 9 drives the driven gear 5 to rotate through the motor 8, and further rotates the rotating plate 6 and cooperates with the engraving knife 20 to process annular barrier belts of different radii.

[0020] The inside of the electromagnetic sleeve 11 is slidably connected with the magnetic block 15, and the bottom of the electromagnetic sleeve 11 is slidably connected with the connecting rod 12 through a circular through hole.

The bottom of the connecting rod 12 extends to the outside of the electromagnetic sleeve 11 and is welded and fixed to the mounting bracket 17. When the engraving knife 20 rotates to process the annular barrier band on the surface of the round seed crystal, it needs to be gradually deepened circle by circle until the annular barrier band is formed.

As the processing depth of the engraving knife 20 increases, the engraving knife 20 needs to be further extended, and the current of the electromagnetic sleeve 11 is increased so that the magnetic block 15 pushes the connecting rod 12 downward, and the pressure sensor 14 is used to detect the pressure between the engraving knife 20 and the round seed crystal to avoid damage to the round seed crystal due to excessive pressure during processing by the engraving knife 20. The engraving knife 20 can be adjusted more accurately through the electromagnetic sleeve 11 and the pressure sensor 14.
