Title:
AUTOMATIC APPARATUS FOR RESISTANCE WELDING UNDERWATER MICRO-WELDING, AND RESISTANCE WELDING UNDERWATER WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/107320
Kind Code:
A1
Abstract:
An automatic apparatus for resistance welding underwater micro-welding, comprising a resistance welding apparatus, an automatically-controlled drive device, a workpiece water tank (107), a welding electrode (110), water, an X-axis sliding stand (103), a Y-axis sliding stand (104), a Z-axis sliding stand (105), and a micro-optical support. The resistance welding apparatus comprises a welding power source (101) and a spot welding head (102); the spot welding head (102) is provided with an electrode clamp (109) on which a welding electrode (110) is mounted; the welding power source (101) is electrically connected to the electrode clamp (109) of the spot welding head (102) by means of an output cable. The workpiece water tank (107) and the Y-axis sliding stand (104) are mounted on a workbench (108) underneath the spot welding head (102), the X-axis sliding stand (103) is mounted on the Y-axis sliding stand (104), the spot welding head (102) is mounted on the Z-axis sliding stand (105) to form an integrated movable automatic spot welding head, and water is added in the workpiece water tank (107). The micro-optical support is mounted at front outside of the spot welding head (102). The automatically-controlled drive device is electrically connected to the X-axis sliding stand (103), the Y-axis sliding stand (104), and the Z-axis sliding stand (105) of the integrated movable automatic spot welding head (102), separately. Also disclosed is a method for resistance welding underwater welding of welded workpieces immersed by water in a workpiece water tank. By adding water in the workpiece water tank to immerse welded workpieces, automatic welding of the welded workpieces positioned in the workpiece water tank is achieved by the movement of the integrated movable automatic spot welding head, the present invention not only provides a new automatic welding apparatus for manufacturing electronic components and parts, but also develop resistance welding from air environment welding to resistance welding underwater welding, thereby solving the technical problem of heat dissipation of resistance welding.
