Abstract
Description
Technical Field
[0001] This utility model belongs to the field of milling cutter manufacturing technology, and relates to a rotating device for PCB milling cutter welding. Background Technology
[0002] Milling cutters are an essential tool in PCB manufacturing. By using the high-speed rotation of milling cutters to drill holes in PCBs, the production speed of PCBs can be increased and the processing difficulty of PCBs can be reduced. Generally, carbide rods and milling cutter rods are welded together to obtain a complete PCB drill bit.
[0003] In the production of existing PCB milling cutters, it is necessary to weld carbide shank stock and drill bit stock together. Before welding, the carbide shank stock and the milling cutter stock need to be butt-joined to make their end faces fit together. Existing welding equipment requires manual loading of materials once, followed by extrusion butt-joining by the equipment. After welding, manual unloading is required, resulting in poor welding efficiency. Therefore, we propose a rotary device for PCB milling cutter welding that can automatically butt-join and unload materials. Utility Model Content
