A welding head

Abstract

The utility model relates to photovoltaic module production technical field, concretely relates to a welding head, it includes: mounting panel, electromagnetic heating spare and first elevating gear and first suction accessory, the electromagnetic heating spare is fixed in the bottom of mounting panel, first suction accessory is located the both sides of electromagnetic heating spare and with the elevating end connection of first elevating gear, first elevating gear sets up on mounting panel or electromagnetic heating spare. First suction accessory is used for adsorbing the cell piece in the battery string group, can lift the cell piece and the bus bar on the cell piece under the action of first elevating gear, when electromagnetic heating spare heats the bus bar, the cell piece below the bus bar separates with EVA film, waits to complete the welding, the cell piece temperature drops, and first elevating gear places the cell piece on EVA film again, and EVA film will not melt.
