Description

TECHNICAL FIELD

[0002] Before welding, the PCB needs to be shaped to the integrated circuit pin to be welded, and the pin forming process is crucial to the reliability of the product. There are currently two ways to form the pin manually and by equipment. The manually formed pin has poor consistency, uncontrollable process, poor size control, and the pin is prone to skew. The free expansion of the pin between the two constraints cannot be guaranteed, and the device pin cannot be guaranteed to be welded to the pad of the relative hole of the PCB. The current equipment for forming the pin has the disadvantages of high equipment cost or low forming efficiency.

[0003] In related technologies, a patent with authorization announcement number CN219052725U discloses an IGBT corner forming tool. The lower die assembly is fixedly connected with the base. The lower die assembly has a sliding groove, and one side of the sliding groove is open. The forming sliding part can slide in the sliding groove. One side of the forming sliding part has a lower pressing edge. The lower pressing edge extends out of the opening. The lower pressing edge has a long foot boss above it. The upper die is fixed below the pressing rod connecting piece. The upper die has an upper pressing edge. The shape of the upper pressing edge matches the lower pressing edge and has at least one long foot groove. The pressing rod connecting piece drives the upper die to move up and down, close to and away from the lower die assembly. Its advantages are that the pins of the same IGBT tube are formed at one time, multiple pins can be formed at the same time, the efficiency is high, the consistency of the component pin forming is strong, and it is suitable for pneumatic and semi-automatic pressing table, and has strong universality.

[0004] For the related technologies in the above, when the pin is pressed and formed, the electronic component needs to be assembled to the forming sliding part first, then the forming sliding part is inserted into the lower die, then the upper die and the lower die are closed to press and form the pin, and finally the electronic component is taken out. This method needs to perform more actions, which reduces the pin forming efficiency. Utility model content
