AI Technical Summary

Technical Problem

In the existing technology, during the packaging and molding process of module wire harness isolation plates, the high-viscosity sealant injected into the narrow mold cavity causes fluid shear impact on the flexible wire harness, resulting in instability, displacement and bending of the flexible wire harness, thus reducing the packaging quality.

Method used

The device employs a combination of servo drive components, piezoelectric ceramic transducers, and miniature support pins. The servo motor drives the polymer sealing liquid, the piezoelectric ceramic transducer induces an acoustic flow effect to reduce the viscosity of the sealing liquid, and the miniature support pins provide adaptive mechanical support to control the fluid shear force during the sealing process.

Benefits of technology

It effectively reduces fluid shear impact, improves the stability of the sealing process and the molding qualification rate, and reduces the risk of displacement and breakage of flexible wire harnesses.

Abstract

本发明涉及模具成型与智能注胶设备技术领域,具体为一种模组线束隔离板的模具封胶装置及其方法;包含模具基座、伺服驱动组件、压电陶瓷换能器、微型支撑顶针及控制器等模块;装置将主注胶流道与顶针尾部的拮抗式液压室经微型毛细流道连通;其核心是利用流体压力变化被动同步控制顶针伸退,进胶升压时顶针自动伸出提供自适应支撑抵御流体冲刷,压力衰减时顶针微退以免影响包覆;本发明无需外部独立液压机构,显著降低了线束受冲刷弯曲或位移的风险,有效提升了封装结构的完整性。
