Hot Press Welding Head, Wire Welding Device and Method

A wire welding device, comprising:

• a hot press welding head, including:
• a main body, having:
• a front side surface and a rear side surface opposite to each other in its transverse direction;
• a curved bottom surface between bottom edges of the front side surface and the rear side surface, the bottom edge of the front side surface is lower than the bottom edge of the rear side surface in a height direction of the main body;
• and
• a plurality of positioning slots formed on the curved bottom surface, and arranged in a row along a longitudinal direction of the main body for simultaneously positioning multiple welded wires, the positioning slots extending along the transverse direction of the main body between the front side surface and the rear side surface;
• and
• a moving device adapted to move the hot press welding head to position a row of wires into the row of positioning slots of the hot press welding head.

A wire welding method, comprising following steps of:

• S10:
• providing the hot press welding head, comprising:
