Abstract

The invention discloses a crucible bubble counting device and a counting method. The device includes a data processing controller and an image acquisition device. The image acquisition device includes a mechanical arm and an electronic magnifying glass installed on the mechanical arm. The electronic magnifying glass and the mechanical arm are all connected with the data processing controller; the method includes the following steps: 1. acquisition and transmission of the crucible image; 2. preprocessing of the magnified image of the bubbles on the inner wall of the quartz crucible; Judgment; 4. Acquisition of the number of bubbles. The invention is reasonable in design and low in cost. The bubble image of the transparent layer in the quartz crucible is acquired through an electronic magnifying glass, and the bubble image is processed to judge whether the crucible meets the standard, which can not only save manpower, material resources and financial resources, but also avoid errors caused by human factors. , It reduces the error rate in manual inspection and improves the automation of quartz crucible inspection.

Description

technical field [0001] The invention belongs to the technical field of crucible bubble detection, and in particular relates to a crucible bubble counting device and a counting method. Background technique [0002] Quartz crucible can be used below 1450 degrees, divided into transparent and opaque. The semi-transparent quartz crucible made by arc method is an indispensable basic tool for drawing large-diameter single crystal silicon and developing large-scale integrated circuits. With the rapid development of photovoltaic industry, the requirements for quartz crucible are getting higher and higher. The crucible only pulls the crystal once, and gradually changes to the secondary feeding during the crystal pulling process, which increases the use time of the crucible. Therefore, the requirements for the number of bubbles in the transparent layer of the quartz crucible and the distance between the bubble surface and the inner surface are becoming more and more stringent. When t...
