Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging product assembly production, and in particular to a wireless charging product assembly welding carrier and a method thereof. Background Art

[0002] Wireless charging products such as Figure 1 As shown, it is composed of a circular connector 01 and a wire 02 welded together. The circular connector 01 is disc-shaped, and a conductor 021 and a shielding crimping wing 022 are provided at the end of the wire 02. The connector 01 and the wire 02 need to be precisely positioned so that the conductor 021 and the shielding crimping wing 022 are located in a predetermined welding area of ​​the connector 01. Currently, there is no integrated welding carrier for this product, and simplified operation and precise positioning cannot be achieved. In addition, the welding process between the connector and the wire includes: shielding crimping wing positioning, shielding crimping wing welding, conductor positioning, conductor welding and conductor soldering point UV sealing. The welding process is complicated. In the welding process of existing wireless charging products, the conductor is welded first, and then the shielding crimping wing is welded. During the welding process of the shielding crimping wing, a force is generated on the conductor soldering point, and the conductor soldering point is easily detached due to the force.

[0003] The Chinese patent with patent number CN210985000U discloses a connection structure between an aluminum cable and a terminal and a vehicle having the same. The specification of the Chinese patent states at end 0037 that "first place the terminal on the positioning block of the ultrasonic welding equipment, move the left and right welding fixtures to press on the terminal, and limit the size between the left and right welding fixtures to the size of the welding head. Place the wire core of the aluminum cable in the two welding fixtures, move the welding head vertically downward, and weld the exposed wire core of the aluminum cable to the terminal."
