Description

Full-automatic PCB circuit board bonding wire and network transformer bonding wire spot welding mechanism

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of welding of PVC circuit boards and welding wires of network transformers, in particular to a full-automatic spot welding mechanism for welding wires of PCB circuit boards and welding wires of network transformers.

[ background of the utility model ]

The traditional PVC circuit board adopts a manual welding mode, and the electric lead is welded on a pin (welding leg) of the PVC circuit board through an electric soldering iron. Manual welding is generally divided into five steps: step one, preparing welding: the left hand holds the welding wire and the right hand holds the soldering iron to enter a standby welding state. Step two, heating the weldment: the soldering iron head is leaned on the joint of the two welding parts to heat the whole welding part. Step three, feeding welding wires: when the soldering surface of the soldering element is heated to-a certain temperature, the solder wire contacts the soldering element from the opposite side of the soldering iron. Step four, removing the welding wire: immediately after the wire melted-quantified, the wire was removed to the upper left 45 degrees. Step five, removing the soldering iron: and after the soldering tin infiltrates the welding position of the welding pad and the welding part, moving the soldering iron to the upper right direction by 45 degrees, and finishing welding.

In the traditional network transformer welding wire, an enameled wire is dipped in tin and then a coating is removed manually, and then the enameled wire is wound on a terminal of a network transformer manually. Manual winding is generally divided into four steps: firstly, arranging a coil and placing the coil in a special tin immersion jig; manually immersing the jig into a tin furnace to remove the enamel on the surface of the enameled wire; winding the enameled wires with the enamel skins removed one by one on a terminal by using tweezers; and step four, taking the tweezers by hand to tear off the redundant wire tail.

The quality of manual welding and manual winding depends on the proficiency and concentration of workers, the labor intensity of the workers is very high, attention needs to be focused, fatigue is easy to occur, personal safety accidents such as scalding of an electric iron and scalding of a tin furnace are easy to occur, and working diseases such as smoke and waste gas generated by the electric iron during welding and tin immersion are easy to generate, and respiratory diseases are easy to cause.
