Multi-functional safety soldering fixture for double chip and copper wire

Abstract

The invention relates to a multifunctional safe welding jig for a bimorph and a copper wire. The multifunctional safe welding jig comprises a welding seat; a lower fixed electrode is arranged in the center of the welding seat, and an upper movable electrode is arranged above the lower fixed electrode; a first fixed seat and a second fixed seat are arranged on the welding seat and on the two sides of the lower fixed electrode, a locating block and a locating frame are arranged on the upper end face of the first fixed seat, and an upper blocking column is arranged on the lateral side of the locating block; a lower blocking column which is staggered from the upper blocking column is arranged on the lateral side of the first fixed seat and below the upper blocking column; the bimorph is arranged between the upper blocking column and the lower blocking column, the square tube end of the copper wire is arranged between the bimorph and the upper blocking column, and the other end of the copper wire abuts against the upper end of the locating frame; a locating column and a locating calibrating frame which are used for limiting a supporting plate are further arranged on the lateral side of the first fixed seat; an end limiting frame is arranged on the second fixed seat, and the end of the end limiting frame is arranged on the upper end face of the lower fixed electrode and abuts against the bimorph, the welding end of a horizontal plate and the end face of the square tube end; and a photoelectric inductive switch is arranged on the end limiting frame.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding jig for double wafers. Background technique [0002] Such as Figure 7 As shown, the workpieces to be welded include a double chip 2, a copper wire 1 and a support plate 3, the copper wire 1 is curved, and its welding end is a square pipe end 101, and the support plate 3 is a multi-bend structure with an upper horizontal The welding end 301 of the plate, the middle bending part 302 in the middle and the lower bending part 303 in the lower part, the bending directions of the middle bending part 302 and the lower bending part 303 are opposite. At present, due to the lack of special welding fixtures, the three parts can only be welded separately by hand, the welding efficiency is low, and the welding quality is difficult to control; moreover, due to the multi-bending structure of the support plate 3, it needs to be calibrated and tested after processing. , At present, an...
