Abstract
A joining apparatus for panel sheets and a joining method for panel sheets using the same are provided. The joining apparatus includes an element punching device which stores and supplies elements according to a specification of a panel sheet and inserts the element into a first panel sheet among different types of panel sheets. Additionally, a welding device resistively welds a part of the first panel sheet into which the element is inserted by the element punching device.
Claims3
A joining method of panel sheets, comprising:
- locating, by a controller, a supply block configured to supply an element in a position that corresponds to a joining portion of different types of panel sheets loaded on a die;
- inserting, by the controller, the element into a first panel sheet among the different types of panel sheets through a punch operated by a punch cylinder to a supply aperture formed in the supply block;
- pressurizing, by the controller, upper and lower electrodes while locating upper and lower electrodes of a welding device that corresponds to upper and lower sides of the joining portion of different types of panel sheets;
- and
- resistively welding, by the controller, the edge of the element to a second panel sheet among the different types of panel sheets through the upper and lower electrodes by supplying power to the welding device.
