TECHNICAL FIELD

[0001] The present application relates to the technical field of DC terminal two-core wire processing equipment, and particularly relates to a full-automatic two-core wire and DC terminal welding and tin sticking machine. BACKGROUND

[0002] DC terminals are widely used in electronic products, and there are various types of DC terminals. Each type of DC terminal usually has two metal contact terminals, and the two metal contact terminals are isolated by a plastic part. Figure 12 As shown in the drawing, it is a common DC terminal two-core wire structure, which comprises a DC terminal 100 and two-core wires 200. The DC terminal 100 comprises a first metal contact terminal 101, a plastic part 102 and a second metal contact terminal 103. The plastic part 102 isolates the first metal contact terminal 101 and the second metal contact terminal 102. The wiring part 1011 of the first metal contact terminal 101 is located at the rear end of the DC terminal, and the wiring part 1021 of the second metal contact terminal 102 is located at the side of the DC terminal. The two-core wire 200 has a long wire head 201 and a short wire head 202. The long wire head 201 is welded to the wiring part 1021 of the second metal contact terminal 102, that is, to the metal connecting part on the side of the DC terminal. The short wire head 202 is welded to the wiring part 1011 of the first metal contact terminal 101, that is, to the metal connecting part at the rear end of the DC terminal. In addition, the end 203 of the DC terminal two-core wire 300 which is not welded to the DC terminal is stuck with tin.

[0003] In the prior art, the welding and tin sticking process of the DC terminal two-core wire is usually completed manually by workers, which is slow, low in efficiency and yield, and poor in consistency, and is more and more unsuitable for enterprise scale production. With the progress of technology, two-core wire and DC terminal welding machines have gradually appeared in the industry. However, the two-core wire and DC terminal welding machines in the prior art still need manual wire loading, wire arranging and wire cutting, and the two-core wire and DC terminal welding machines in the prior art can only weld two-core wires with the same length of wire heads. It is difficult to weld two-core wires with different lengths of wire heads as shown in the drawing. Figure 1
