[0025] By arranging a rotating motor inside the processing table box 1, the processing table box 1 drives the material turntable 4 to rotate, and at the same time, a plurality of material trays 5 are arranged on the top surface of the material turntable 4, so that when the staff places the insulating film on the material tray 5 through the loading device 2, by rotating the material turntable 4, the material turntable 4 moves an insulating film to the identification device 3 for detection and identification, and at the same time, the material turntable 4 moves another material tray 5 to the loading device 2 for loading, and at the same time, the identification device 3 after the detection and identification is completed is moved to the adsorption head 7 for welding, which solves the problem that the traditional welding device usually has only one workstation, and the insulating film needs to complete the working procedures such as loading, detection, thickness identification, etc. before welding, and the welding efficiency is low, which is difficult to meet the needs of mass production.

[0026] Specifically, the conveying device includes a slide bar 13, which is fixedly connected to the second gantry 12. A first cylinder 14 is fixed at one end of the slide bar 13.
