Description

Technical Field

[0001] The utility model relates to the field of quartz thermal processing, in particular to a rotary welding boss workstation. Background Art

[0002] Quartz has a series of properties such as high hardness, high purity, low thermal expansion coefficient, electrical insulation and chemical stability. It is an important carrier in the preparation of photovoltaic cells and semiconductor chip manufacturing processes, and its demand is growing.

[0003] Photovoltaic grade quartz products are indispensable raw materials in the photovoltaic field. In the production process of solar cells, wafers are the basic raw materials, and their diffusion, oxidation, etching and other links all require the consumption of a large number of quartz boats, quartz boat trailers and other quartz products. Diffusion requires that the carrier does not deform in a high temperature environment of 1100°; etching requires that the carrier does not undergo chemical reactions in a strong acid solution; therefore, the requirements for the carrier material are extremely high.

[0004] At present, in the production of quartz boats, bosses are often required on the side panels, and the two quartz materials usually need to be bonded by flame welding. The specific method is: fill in the wire first and then grind it flat. This method is not only cumbersome, but also takes a long time to prepare for welding. Before welding, workers need to use auxiliary tools such as graphite blocks to fix the quartz parts to be welded in advance, so that the bosses and the reserved holes on the side panels are positioned, and then fill in the reserved holes by filling in the wire, and finally grind the side panels flat. Filling in the wire welding takes a long time and the side panels need to be processed with holes in advance. The process is relatively backward, and the overall processing efficiency is low.
