Then the pulling plate translation module drives the sheet jig to translate, so that the sheet jig moves to the top of the end of the jig sliding bearing plate close to the welding mechanism, and the sheet jig is pulled. The shift spring is always in a compressed state. After the sheet jig reaches the welding station of the welding mechanism, the upper and lower welding needles of the welding mechanism can weld the coil and the sheet to be welded, so that the coil is connected to the sheet. After welding is completed, the pull plate translation module pulls the sheet jig back to its original position, so that the sheet jig moves to the top of the jig through hole of the jig sliding support plate. At this time, the spring returns to its normal state and pushes the sheet jig down to the second jig placement plate. Then the second jig placement plate descends, so that the sheet jig is placed back on the supporting wheel of the sheet conveying line. The sheet conveying line then conveys the sheet jig to the welding station of the laser welding mechanism. Among them, the size of the welding through hole of the jig sliding support plate is smaller than that of the sheet jig to ensure that the sheet jig will not fall into the welding through hole when it moves to the top of the welding through hole.

[0074] During operation, the sheet conveying line transports the sheet fixture to the bottom of the laser lens, and the laser lens welds the coil and the sheet together.

[0075] In this embodiment, the electric welding mechanism and the laser welding mechanism are provided simultaneously. The electric welding mechanism first welds the coil and the sheet together, and then the coil and sheet are transferred to the bottom of the laser lens. The laser lens can re-laser weld the sheet that was poorly welded in the electric welding station to ensure the yield rate. Of course, in other embodiments, the electric welding mechanism and the laser welding mechanism can also be provided separately, and this embodiment is not limited thereto. If the electric welding mechanism is not provided, the fixture shifting mechanism is also unnecessary.

[0076] In summary, the present invention has a simple, novel structure and reasonable design, and is provided with a sheet leveling mechanism for leveling the sheet, a sheet feeding driving mechanism for driving the sheet to advance and feed the sheet, a sheet cutting mechanism for cutting the sheet, a sheet transfer mechanism for receiving the cut sheet and transferring the sheet to the suction station of the suction transfer mechanism, a sheet pushing and aligning mechanism for pushing the sheet from the side of the sheet discharge plate of the sheet transfer mechanism so that the sheet is placed side by side in the sheet discharge trough of the sheet discharge plate, and a sheet aligning mechanism for sucking the sheet. The material suction and transfer mechanism is used to transfer the material to the material fixture, the material conveying line is used to drive the material fixture to move to realize the conveying of the material, the electric welding mechanism is used to weld the coil and the material together, and the laser welding mechanism is used to weld the coil and the material together by laser welding.
