[0002] The sun visor is composed of two groups of sun visor bodies and a supporting frame, and a rotating shaft is arranged between the two groups of sun visor bodies. In the existing sun visor processing process, most of the heating plates are directly in contact with the product to heat the hot-melt ribs on the product, which is easy to cause problems such as wire drawing and overflow in the process. After the product is processed, the product needs to be manually reworked and trimmed. In addition, the heat is easily uneven during the processing, which affects the hot-melt effect of the ribs and causes the welding to be weak. Moreover, the sun visor body is mostly foamed, and the incoming material may be uneven in thickness. The traditional method of contact hot pressing is likely to cause uneven edge wrapping and uneven thickness of the product, which seriously affects the welding quality of the product. Therefore, the existing sun visor processing needs to be improved. Summary of the invention
