Description

Bonding wire fixed establishment

Technical Field

The utility model relates to a PCB board field of making has especially related to a bonding wire fixed establishment.

Background

When the PCB and the external connection control plate are welded by a wiring soldering machine, the welding wires need to be sorted, positioned, clamped and spot-welded on the soldering machine. In the traditional manual wire welding mode, a welding wire head is accurately inserted into a welding point hole corresponding to a PCB by hands, a welding gun is held in a certain posture for welding, only one wire head can be welded and then penetrates through another welding point hole for welding, and the cycle is repeated. The manual welding wire utilizes the dexterity of hands and the visibility of eyes to judge that the welding wire with the corresponding color is inserted into the corresponding welding hole, so that the manual welding wire has low efficiency. However, after the pure manual mode is changed into automatic welding by a soldering machine, due to the soft and zigzag characteristic of the welding wire, the welding wire head can not be ensured to penetrate through the welding hole of the PCB to complete accurate alignment welding every time, so that the mass production efficiency and the yield are low. In addition, after the semi-automation is changed, welding wires with different colors need to be sorted quickly and inserted into corresponding welding holes quickly, and due to the fact that the hole positions are not distributed uniformly, it is required to guarantee that each wire harness can keep the installation state of being inserted into the welding holes, and all point positions are completed on a soldering machine through one-time spot welding, so that the situations that wire harness positioning is not prepared and welding positions are wrong can be caused.
