Description

Technical Field

[0001] This utility model relates to the field of core wire coating machine technology, and in particular to a high-precision automatic core wire sorting and coating machine. Background Technology

[0002] In the modern electronics, communications, and electrical equipment manufacturing industry, the core wire, as a key component for transmitting electrical signals or energy, directly affects the performance of the end product due to its processing quality. Currently, traditional core wire sorting and coating equipment suffers from several technical bottlenecks: First, the lack of an effective tension adjustment mechanism during core wire transport easily leads to slack or excessive tightness, resulting in unstable core wire transport and positional deviations. This causes uneven coating thickness and missed coatings during the coating process, making it difficult to meet high-precision coating requirements. Second, in terms of the coating process, the coating liquid spraying uniformity is poor, requiring significant manual intervention and exhibiting low automation, making it difficult to meet the needs of large-scale production. Third, in the post-coating drying stage, most equipment uses natural drying or inefficient drying methods, resulting in long drying times and uneven heating, which easily leads to quality defects such as coating layer cracking and blistering. This severely affects the insulation and wear resistance properties of the core wire, resulting in insufficient stability and reliability when used in complex environments. Therefore, we propose a high-precision automatic core wire sorting and coating machine to solve this problem. Utility Model Content

[0009] Preferably, multiple heating plates are fixedly installed inside the heating box, the heating box is fixedly installed on the top of the drying box, and the box plate is fixedly installed on the inner walls of both sides of the drying box.

[0010] Preferably, multiple sets of wire-threading grooves are provided inside both sides of the coating box.

[0011] In this invention, a high-precision automatic core wire sorting and coating machine is provided, comprising a tensioning component and a coating component.

Stable tension ensures that the core wire is transported smoothly when entering the coating box, providing a stable substrate for subsequent coating processes. This helps to improve the uniformity and consistency of coating and avoids problems such as uneven coating thickness caused by core wire shaking or positional deviation. It can stably and evenly spray the coating liquid onto the core wire, ensuring that all parts of the core wire surface can be uniformly coated, meeting the requirements of high-precision coating and greatly improving coating efficiency.

Inside the drying chamber, a blower sends air into a heating chamber. Multiple heating plates within the heating chamber heat the air. The hot air enters a tray through an air outlet pipe and is then blown out through multiple exhaust pipes at the bottom of the tray. The multiple heating plates rapidly heat the air, providing sufficient heat to the core wire coating liquid, accelerating solvent evaporation and the curing reaction, significantly shortening the drying time. The even distribution of hot air ensures relatively uniform heating of all parts of the core wire, preventing quality defects such as cracking, blistering, and uneven curing caused by localized overheating or undercooling. This ensures a smooth coating appearance and consistent performance, improving the stability and reliability of the core wires used in different environments. Attached Figure Description
