Micro-lens array grinding device and micro-lens array grinding method

Abstract

The invention discloses a micro-lens array grinding device and a micro-lens array grinding method and relates to the technical field of grinding. A horizontal moving device in the micro-lens array grinding device is installed on a base in a slidable manner, a lifting device is installed on the horizontal moving device in a slidable manner, an elastic body working platform is fixedly installed on the lifting device, ascending and descending directions of the lifting device, a sliding direction of the horizontal moving device and a sliding direction of the lifting device are vertical to each other, a supporting device and the base are fixedly connected, a grinding head is fixed on the supporting device, and a grinding end face of the grinding head is opposite to a to-be-processed work piece,a power device is connected to the grinding head, and a vibration generating device is fixedly connected to the elastic body working platform. When the micro-lens array grinding device is used for grinding, the vibration generating device applies vibration on the elastic body working platform so that a micro-lens array has high processing efficiency. In addition, the lifting device and the horizontal moving device accurately adjust the location and processing depth of the to-be-processed work piece, thus the micro-lens array has good processing consistency and high processing accuracy.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a microlens array grinding device and method. Background technique [0002] At present, the processing methods of microlens mainly include grinding, milling, molding, injection molding, ball grinding and so on. Grinding removes excess material through a large number of high-speed abrasive particles; milling removes excess material through cutting edges; ball grinding removes excess material through the movement of balls to drive free abrasive movement; both injection molding and molding use materials to melt and fill in the mold. Form microlenses. The above-mentioned microlens processing method is only applicable to the processing of a single microlens. When the microlens array is processed, the consistency between the microlenses cannot be guaranteed. The consistency between the microlenses is poor, the processing accuracy is low, and the processing takes a long time. low eff...
