Abstract

The invention discloses a quartz crucible bubble layered counting device and method, the device comprises a data processing controller, a miniature projector and an image acquisition device, the imageacquisition device comprises a mechanical arm and an electronic magnifying lens, and the light projected by the miniature projector is blue-violet light; The method comprises the following steps: 1,collecting and transmitting a quartz crucible image; 2, denoising and balancing the amplified image of the quartz crucible; 3, layering bubble images of the quartz crucible; And 4, acquiring the bubble contour of the bubble layering image of the quartz crucible. The device is reasonable in design, the bubble image of the transparent layer in the quartz crucible is obtained through the electronic magnifying lens, and the bubble image is subjected to layering processing, so that whether the quartz crucible production process reaches the standard or not is judged, manpower, material resources andfinancial resources are saved, and the automation degree of quartz crucible inspection is improved.

Description

technical field [0001] The invention belongs to the technical field of bubble detection in a quartz crucible, and in particular relates to a layered counting device and method for bubbles in a quartz crucible. Background technique [0002] Quartz crucibles are widely used in many important fields, especially in single crystal silicon for manufacturing semiconductor electronic components, quartz crucibles are the main equipment, and the bubbles in the transparent layer of quartz crucibles greatly affect the crystal pulling results, so It is extremely important to select an experimental quartz crucible with a small number of bubbles. The cross-section of the quartz crucible usually has a double-layer structure: the inner layer is colorless, called the transparent layer, characterized by transparency, less bubble content, spherical and evenly distributed bubbles; the outer layer is white, called the opaque layer, characterized by It is opaque and contains a lot of bubbles, and...
