AI Technical Summary
Technical Problem
Traditional processing techniques cannot meet the requirement of not chamfering the edges of high-precision optical guide rod parts, resulting in frequent edge chipping and affecting product yield.
Method used
The method of using photopolymer adhesive is adopted. The edges of the light guide rod are protected by the first and second mounting plates. The side and end faces are processed first, then the coating is applied, and finally the mounting plates are removed to avoid edge chipping.
Benefits of technology
It significantly reduces the risk of edge chipping of optical guide rods, improves product yield and vertical accuracy, and protects the processed surface.

Abstract
The application relates to the technical field of optical part processing, and provides a light guide rod processing method based on optical cement, which comprises the following steps: processing a first side surface and a second side surface to a first surface shape parameter, and cementing a first distribution disc on the first side surface and the second side surface; cementing the first distribution disc to a body, processing a third side surface, a fourth side surface and the first distribution disc to the first surface shape parameter and flush with the first distribution disc, and cementing a second distribution disc on the third side surface and the fourth side surface; processing a first end surface, a second end surface, the first distribution disc and the second distribution disc, processing the first end surface and the second end surface to a second surface shape parameter and flush with the first distribution disc and the second distribution disc, and coating films on the first end surface and the second end surface; removing the second distribution disc and the first distribution disc, and obtaining a light guide rod. The first distribution disc and the second distribution disc can participate in subsequent sanding and polishing, the risk of edge collapse of the edges of the side surfaces and the edges of the end surfaces can be greatly reduced, the vertical precision of the light guide rod at the edge position is improved, and the product yield is greatly improved.
