Terminal manufacturing apparatus and welding apparatus

A terminal manufacturing apparatus comprising:

• a pressing device adapted to form, on a continuously supplied plate-shaped workpiece, a butted portion between respective ends of a plate material bent to have a hollow cross-section and a lapped portion in which one end of the plate material is overlapped in planar form;
• a welding device adapted to join the butted portion and the lapped portion by welding;
• and
• a welding inspection device adapted to measure a bead width of the welded butted portion and lapped portion.

A terminal manufacturing apparatus comprising:

• a pressing device adapted to form a chained terminal including a crimp portion by bending a continuously supplied plate-shaped workpiece into a hollow shape, the crimp portion being crimpable with a conductor part of a coated conductor accommodated therein;
• a welding device adapted to bring two edge portions of the crimp portion in proximity to each other and join the two edge portions by welding;
• a position detection sensor adapted to detect a sag amount of the chained terminal, the position detection sensor being provided on a conveyance path of the chained terminal between the pressing device and the welding device;
• a positioning time adjusting unit adapted to adjust conveying/positioning time of the welding device in accordance with the sag amount;
• and
• a conveying/positioning mechanism adapted to position the chained terminal in a welding machining position within the welding device in accordance with the conveying/positioning time.
