Description

Technical Field

[0001] This utility model relates to the field of quartz boat support processing technology, and in particular to an automatic welding equipment for quartz boat supports. Background Technology

[0002] Quartz boat support, also known as a quartz boat, quartz carrier, or quartz basket, is a high-purity quartz glass product widely used in industries such as semiconductors, photovoltaics (solar energy), LEDs, and precision glass processing. It is primarily used to support and transport silicon wafers, solar cells, or other precision substrates during high-temperature processes (such as diffusion, oxidation, annealing, CVD, etc.).

[0003] During the manufacturing process of quartz boat supports, the side plates and grooved bars need to be welded together. After welding, the toothed grooves on the four grooved bars form a flat surface. The flame welding method for quartz boat supports mainly involves the use of flame brazing technology, a method that melts the solder by heating it with a flame, thereby achieving the connection between two or more workpieces. A flame welding torch is a welding torch that uses combustible gas to ignite and heat the workpiece. It generally consists of three parts: a hose, a handle, and a welding nozzle. The hose connects the gas cylinder to the welding torch, the handle is the part that the worker grips (usually with an airflow control valve), and the welding nozzle is the part that emits the flame (it may have an electronic ignition device).

[0004] Although some automated welding equipment is currently available on the market, it still has shortcomings in terms of adaptability, precision, and structural design. For example, existing equipment often struggles to meet the welding needs of various sizes of quartz boat supports, and insufficient positioning accuracy can easily lead to weld misalignment or incomplete welds, limiting its widespread application in actual production. Utility Model Content
