New Method for Surface Atomization of The Mold Cavity of The Mobile Lens

针对手机镜头中镜片模具模仁非有效径表面雾化颗粒度要求高的特征,提出一种加工手机塑胶镜片模仁非有效径表面雾化的新方法,即利用超声振动切削将模仁非有效径表面。研究内容包括:理论分析利用超声振动加工模仁非有效径雾化表面原理;实验验证利用超声振动加工模仁非有效径雾化表面可行性。研究结果表明,利用超声振动切削方法可以加工镜片模仁非有效径雾化表面,且此方法相较于电火花加工方法表面反光亮度低,表面纹理规则程度高,雾化效果好。

Because of the high requirement of atomizing particles on the non-effective diameter surface of the lens mould kernel in mobile lens,a new method for processing the non-effective diameter surface atomization of mobile phone plastic lens mould kernel is proposed. The non-effective diameter surface of the mold was machined by ultrasonic vibration. The research content includes:the principle of non-effective diameter atomizing surface of mold kernel by ultrasonic vibration is analyzed;the non effective diameter atomizing surface of mold kernel was processed by ultrasonic vibration. The results show that the non-effective diameter atomizing surface can be processed by ultrasonic vibration cutting.Compared with EDM,this method has low reflectance,high regularity of surface texture and good atomization effect.
