[0030] The working principle of this utility model:

[0031] Welding position positioning: The jig 13 loaded with the workpiece 14 is fixedly placed on the slide 12, and the slide 12 slides to the processing position on the workpiece guide rail 11. The visual inspection device 22 slides along the first slide rail 21, shoots the workpiece on the slide 13, and locates the position of the lead to be welded on the workpiece 14, and transmits the shooting results to the external control mechanism. The external control mechanism controls the soldering mechanism 4 to move in the horizontal and vertical directions, and aligns the end of the soldering iron 44 with the position of the lead to be welded.

[0032] Automatic tin supply and tin breaking: The tin breaking and tin supply component 5 transmits the welding wire 45 after the pressing hole is tin-broken to the soldering mechanism 4. First, the welding wire I-shaped wheel is put on the feeding wheel 52. After the welding wire 45 is tensioned downward through the two tensioning wheels 511, the wire is fed downward from the wire feeding groove 5331 of the wire feeding wheel 533; the action of breaking the tin of the welding wire is controlled by the operating lever 561. The operating lever 561 is rotated to make the cam 56 push the driven shaft 541 close to the rotating shaft 531, and the driven gear 542 is engaged with the driving wheel 532. At the same time, the teeth of the tin-breaking cutter wheel 543 penetrate the welding wire 45 and rotate simultaneously with the downward transmission of the welding wire 45. The welding wire 45 transmitted downward through the wire feeding groove 5331 completes the tin-breaking operation. The welding wire after tin breaking has good meltability and fluidity, and tin is not easy to explode and splash during the welding process.

[0033] Automatic welding: The soldering wire 45 after tinning is continuously fed to the end of the electric soldering iron 44 through the wire feeding sleeve 433. Before welding, the installation position and welding angle of the electric soldering iron 44 are pre-adjusted through the arc-shaped adjustment long hole 421. The Z-axis slide rail 32 slides on the second slide rail 31 to adjust the position. The slide plate 33 slides downward along the Z-axis slide rail 32 to align the electric soldering iron 44 with the workpiece 14. During welding, the combustion-supporting agent gas pipe 431 blows the combustion-supporting agent to the welding outlet, so that welding can be carried out automatically and accurately and efficiently.

[0034] Cleaning solder slag after welding: After welding is completed, clean the residual tin slag at the end of the electric soldering iron 44. The electric soldering iron 44 is moved to the top of the tin slag box, and the cylinder 41 extends the electric soldering iron 44 downward into the tin slag box 61. The air blowing head 63 blows high-pressure gas to the end of the electric soldering iron 44 to blow the tin slag into the tin slag box 61 for collection. The electric soldering iron 44 can be used for the next welding only after cleaning.

[0035] During the automatic welding process, the exhaust pipe 7 extracts the welding area throughout the entire process to ensure that there is no smoke or dust in the welding area.

[0036] The above descriptions are merely some preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes and substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
