Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding device. Background Art

[0002] A quartz boat, also known as quartz glass, is mainly composed of silicon dioxide. Quartz glass has excellent properties such as high purity, high temperature resistance, low thermal expansion, and strong chemical stability. Therefore, in the production of photovoltaic wafers, the quartz boat is used as a carrier for photovoltaic wafers and is widely used in processes such as texturing, diffusion, and cleaning. Therefore, the quartz boat has high precision requirements to ensure that it can effectively carry photovoltaic wafers.

[0003] Please refer to Figures 1 to 2 As shown, a workpiece to be welded of a quartz boat 80 includes side plates 81, groove bars 82, and ring plates 83. Among them, there are two side plates 81, four groove bars 82, and several ring plates 83. The ends of the four groove bars 82 are distributed on the outer edge of the side plates 81 and are located in the middle and lower parts of the side plates 81. A plurality of grooves are provided on the edge of the groove bar 82. The plurality of grooves are spaced apart along the length direction of the groove bar 82. The edge of the ring plate 83 needs to be effectively welded in the corresponding groove.

[0004] In the prior art, the welding device of the quartz boat cannot meet the assembly and welding requirements of the ring plate and the groove bar. For example, if the ring plate is fixed by manually lifting the ring plate and the ring plate and the groove bar are welded, it takes a long time, has high technical requirements for operators, low precision, and low safety performance.

[0005] Therefore, it is difficult to fix the ring plate in the groove. The existing fixing device cannot meet the requirement of fixing the ring plate. When the fixing device or the operator separates from the ring plate after the seam between the ring plate and the groove bar is welded, the ring plate may be accidentally scratched, damaging the welding between the ring plate and the groove bar, and thus causing welding defects in the quartz boat. Summary of the Utility Model
