Wherein, the supporting member 200 is connected to the base 100, and the supporting member 200 is used for supporting the soaking plate. A heat source is located at the support 200 for heating the soaking plate located on the support 200. The upper pressing component 300 comprises an upper pressing piece 310, the upper pressing piece 310 comprises a first pressing part 311 and a second pressing part 312, a welding gap 313 is formed between the first pressing part 311 and the second pressing part 312, the upper pressing piece 310 is located above the supporting piece 200, the upper pressing piece 310 can move up and down relative to the supporting piece 200 to abut against the upper surface of the soaking plate located on the supporting piece 200, and laser can weld the soaking plate through the welding gap 313.
