Description

Technical Field

[0001] This utility model relates to the field of quartz boat production technology, and in particular to a quartz boat forming auxiliary device for silicon wafer diffusion in solar cells. Background Technology

[0002] Silicon wafer diffusion is a crucial step in solar cell manufacturing. It involves diffusing dopants onto the silicon wafer surface to form a PN junction, thereby endowing the wafer with photoelectric conversion capabilities. During diffusion, the silicon wafer needs to be heated uniformly within the diffusion furnace to ensure even diffusion of the dopants to the wafer surface. Quartz boats, with their excellent thermal conductivity, ensure uniform temperature distribution across the silicon wafer throughout the diffusion process, preventing overheating or excessive temperature differences. Quartz boat forming auxiliary equipment, through high-temperature control technology, helps manufacture quartz boat products that meet specifications.

[0003] In the production of quartz boats, the surface of the quartz boat is first cleaned to remove oil, dust and impurities to ensure welding quality. The quartz boat to be welded is placed on an auxiliary device, and a clamp is used to ensure that the quartz boat does not shift during the welding process and to keep the welding of the quartz boat stable. The quartz boat is welded by heating. After welding, the welded parts are inspected to ensure that the welded parts are flat and smooth.

[0004] However, in the existing technology, some quartz boat forming auxiliary devices can only fix quartz boat side plates of the same size when using clamps to fix quartz boat side plates, and cannot fix quartz boats of different sizes, resulting in low practicality of the device. To solve the above problem, a quartz boat forming auxiliary device for silicon wafer diffusion in solar cells is proposed. Utility Model Content

[0015] As a further description of the above technical solution:

[0016] The bottom of the second rotating shaft is fixedly connected to the top of the base, and the outside of the rotating block is rotatably connected to the second rotating rod, which is rotatably connected to the outside of the first bracket.

Releasing the pressure rod causes the spring to return to its original deformation, causing the limiting block to press the support column tightly, so that the position of the support column will not shift during the welding process of the quartz boat, resulting in a better welding effect for the quartz boat.
