After the material is transported to the preset welding position, the rotation driving piece 231 stops rotating, the lifting driving mechanism 24 drives the transmission roller mounting frame 21 to descend, and the transmission roller 22 is separated from the material, so that the material is stably placed on the welding platform 11, and the welding machine 100 is convenient for accurately welding the material. Compared with manual material handling, the material conveying device 20 of the application can improve the working efficiency and meet the requirement of mass production.
