[0021] Usage process:

[0022] When the present utility model is in use, first, the solder reel 52 wound with the solder wire is assembled on the support shaft 51. Then, a solder wire with an appropriate thickness is selected according to the terminal welding requirement. The solder wire is passed through the wire guiding hole 49 on the support frame, then passes between the guiding wheel 44 and the driving wheel 47, and passes out through the first guiding tube 421 on the support plate 42. Then, the solder wire passes through the second guiding tube 75 on the support beam 73 until the end of the solder wire extends above the support block 61. Then, according to the thickness of the solder wire, the distance between the driving wheel 47 and the guiding wheel 44 is adjusted. The two adjusting nuts 46 are rotated respectively, and the support frame 43 rotates around the adjusting bolt 431, so as to adjust the position of the guiding wheel 44 on the support frame 43. When the guiding wheel 44 and the driving wheel 47 tightly hold the solder wire, the motor 48 is started. The motor 48 drives the driving wheel 47 to rotate. Under the combined action of the driving wheel 47 and the guiding wheel 44, the solder wire is continuously conveyed above the support block 61. Under the action of the manipulator 3, the soldering iron 31 melts the solder wire and welds the terminals placed on the support block 61.
