Description

Technical Field

[0001] This utility model relates to the field of twist needles, specifically a twist needle assembly straightening mechanism. Background Technology

[0002] In the production of twisted needles, the assembly of the twisted needle and its base is called a component. Some components have misaligned needle tips, thus requiring tools to straighten them. Currently, misaligned components are mainly straightened manually using straightening fixtures. Because the components are small and require full inspection, this method significantly increases the workload of operators. Furthermore, operator fatigue can easily lead to missed steps, severely impacting the overall product quality.

[0003] To facilitate operators in quickly identifying defective assemblies, assemblies that fail inspection are usually picked out first. After the entire batch is inspected, assemblies with misaligned needles are manually straightened, resulting in low production efficiency. Utility Model Content
