The invention provides a soldering mechanism 100, wherein the soldering mechanism 100 comprises a welding gun 20 and a shaping assembly 10, the shaping assembly 10 is fixed on the welding gun 20, and a welding wire corresponds to the position of a soldering iron head of the welding gun 20. The shaping assembly 10 is configured to shape the bonding wire 30, that is, the straight bonding wire 30 is shaped into the curved bonding wire 30, and when the soldering iron tip of the welding gun 20, which is obliquely disposed, contacts with the bonding wire 30, the contact area between the bonding wire 30 and the soldering iron tip can be increased, so that the heating efficiency of the soldering iron tip on the bonding wire 30 is increased, more bonding wires 30 are changed into a melting state, so as to facilitate the welding of the bonding head and the multi-core wire, and further enhance the welding strength of the bonding head and the multi-core wire.

As shown in fig. 1 and 2, the shaping assembly 10 includes a holder 11 and a shaping head 12, the holder 11 is provided with a guide cylinder 13, and the guide cylinder 13 is used for accommodating the welding wire 30; the shaping head 12 is slidably disposed on the holder 11, the shaping head 12 includes a first shaping member 121, a second shaping member 122 and a torsion spring (not shown in the figure), the first shaping member 121 and the second shaping member 122 are respectively located at two opposite sides of the guide cylinder 13, one end of the first shaping member 121 and one end of the second shaping member 122 are rotatably connected, the torsion spring is disposed at the rotary connection position of the first shaping member 121 and the second shaping member 122, and is used for driving the other ends of the first shaping member 121 and the second shaping member 122 to approach each other; wherein, one end of the first shaping element 121 facing away from the torsion spring is extended away from the guide cylinder 13.

When the shaping head 12 is moved to the position of the guide cylinder 13, the force of the guide cylinder 13 on the first and second shaping members 121 and 122 may separate the ends of the first and second shaping members 121 and 122 so that the first and second shaping members 121 and 122 are located on opposite sides of the guide cylinder 13, respectively. When the shaping head 12 slides to the position of the bonding wire 30 relative to the holder 11, since the end of the first shaping member 121 extends away from the guide cylinder 13, the second shaping member 122 will abut against the bonding wire 30 and move toward the first shaping member 121, so that the shape of the bonding wire 30 is consistent with the shape of the surface of the first shaping member 121, that is, the shape of the bonding wire 30 will extend away from the guide cylinder 13 to form a curved end, thereby increasing the contact area between the obliquely arranged soldering iron head and the curved bonding wire 30.

Further, as shown in fig. 1 and 3, fig. 3 is an enlarged partial schematic view of the shaping assembly 10 and the soldering tip in accordance with an embodiment of the present invention.

The assembly holes 61 corresponding to the 4-head scale are uniformly arranged at intervals around the circumference of the mounting disc 60, and the central angle between the adjacent assembly holes 61 is 90 degrees. By processing the scale and the fitting hole 61 in the mounting plate 60 in advance, the fixing step of the welding unit can be simplified, and the assembling efficiency of the welding unit can be improved.

Further, as shown in fig. 5 and 6, fig. 5 is a schematic perspective view of a soldering mechanism 100 according to another embodiment of the present invention, and fig. 6 is a schematic partially enlarged view of fig. 5.

As shown in fig. 7 and 8, fig. 7 is a schematic perspective view of a wire feeding assembly 70 in an embodiment of the present invention, and fig. 8 is a schematic plan view of the wire feeding assembly 70 in fig. 7. The wire feeding assembly 70 includes a support block 71, a moving cylinder 72, a mounting head 73, and two clamping jaws 74.

Alternatively, the cross-sectional shapes of the guide groove 741 and the slider 711 may be dovetail-shaped, so that the two jaws 74 may be held on the support block 71 by the shapes of the slider 711 and the guide groove 741, and may be positioned by the slider 711 and the guide groove 741, to simplify the structure of the thread feeding assembly 70 and improve the assembling efficiency of the thread feeding assembly 70.

And a double-point connection structure is formed between the mounting plate 60 and the base 80, so that the lifting driving member 90 can be prevented from being damaged due to the rotation of the mounting plate 60 relative to the base 80.
