Description

Technical Field

[0001] The utility model relates to the technical field of bonding wire production, in particular to a drawing tool for bonding wire production equipment. Background Art

[0002] Drawing tooling plays a vital role in bond wire production equipment. The following explains its role in detail: First, the drawing tooling, particularly the drawing die, is a key component in bond wire production equipment. It is used to stretch and deform materials, such as aluminum wire, to produce bond wires that meet specific requirements. Through a precise drawing process, the size, shape, and surface quality of the bond wires are guaranteed to meet predetermined standards. Second, the drawing tooling helps improve the physical properties of the bond wires. During the drawing process, the material undergoes a certain amount of stretching and deformation, which not only increases the bond wire's strength and hardness, but also improves its durability and load-bearing capacity. This is crucial for ensuring the stability and reliability of the bond wires during subsequent use. Furthermore, the drawing tooling offers high flexibility. Because the drawing die can be replaced and adjusted as needed, bond wires of varying sizes and specifications can be easily produced. This flexibility enables bond wire production equipment to adapt to a variety of application scenarios and needs. Finally, the drawing tooling helps improve production efficiency. Through precise drawing control and efficient tooling design, production cycle times can be significantly shortened and production efficiency improved. At the same time, since the drawing tool can ensure the quality and specification uniformity of the bonding wire, it can also reduce the scrap rate and rework rate, further reducing production costs.

[0003] Traditional drawing fixtures used in bonding wire production equipment have shortcomings. First, they fail to adequately lubricate the wire during the drawing process, making it prone to breakage. Second, they fail to promptly remove metal debris generated during the lubrication process, which can easily cause scratches on the wire surface. Therefore, optimization and improvement are needed.
