Description

Technical Field

[0001] The present disclosure specifically discloses a quartz crucible production technology field, and in particular relates to a quartz crucible surface bubble detection device. Background Art

[0002] Quartz glass crucibles are translucent quartz glassware melted using a high-temperature arc method. To ensure stability and heat preservation during crystal pulling, the quartz crucible needs to be designed with a bubble layer and a bubble clean layer. The quality assurance of these two layers is exactly opposite. The bubble layer is located on the outside of the crucible, requiring uniform and dense bubbles and ensuring bubble stability. The bubble clean layer is just the opposite. The cleaner the bubbles, the better for crystal pulling. Special process crucibles must have a certain number of bubbles in specific locations. The requirements for crucible bubbles are getting higher and higher, and so are the requirements for crucible detection equipment.

In addition, the existing detection device cannot adjust the detection lens and cannot detect different positions of the crucible, resulting in reduced detection effect. For this reason, we propose a quartz crucible surface bubble detection device. Summary of the Invention
