AI Technical Summary
Existing wire drawing machines are prone to breakage during the drawing process due to electrostatic effects and humid air in cleanroom environments, especially for sensitive materials such as silver alloy wires, where electrostatic adsorption of microparticles and oxidation damage are severe.
High-purity dry nitrogen is used as the dust removal medium. Through the design of spiral guide vanes and spiral guide grooves with forward and reverse swirl, microparticles on the surface of the wire are stripped off and filtered by filter plates to form a stable airflow field, avoiding electrostatic adsorption and oxidation damage.
It effectively prevents the bonding wire from breaking during the drawing process, improves the surface cleanliness and integrity of the wire, enhances the grain boundary strength, and avoids wire breakage problems caused by static electricity and oxidation.
