Multi-cutter mechanism and using method of high-efficiency precise cutting micro-structure and using method

Abstract

The invention belongs to the technical field of precision cutting processing, and discloses a multi-cutter mechanism and a using method of a high-efficiency precise cutting micro-structure. The multi-cutter mechanism comprises a cutter assembly and a workpiece assembly, wherein the cutter assembly comprises a first cutter holder, cutter mounting bases and cutting cutter heads fixed on the cutter mounting bases, the first cutter holder is fixed on a cutter feeding guide rail of an engraving machine tool, and two cutter mounting bases are arranged; the workpiece assembly comprises a workpiece driving device and a workpiece clamping seat arranged on the workpiece driving device; and the workpiece driving device comprises a linear driving device and a rotary driving device. According to the multi-cutter mechanism and the using method, the row-by-row multi-cutter structure is adopted, so that simultaneous cutting of a plurality of cutter heads is effectively realized, and therefore the purpose of improving the cutting efficiency is achieved; compared with a traditional single-head cutting, the mechanism can be suitable for larger workpieces or modules in the cutting process, so that theeffect of reducing the number of splicing times of workpieces or modules is achieved, and the quality of final finished products is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of precision cutting, and in particular relates to a multi-knife mechanism for high-efficiency and precise cutting of microstructures and a method of use thereof. Background technique [0002] The so-called precision machining refers to the processing technology with extremely high machining accuracy and surface quality. The most mature precision machining in the existing technology is lithography technology. However, the high price of lithography equipment leads to relatively high processing costs for corresponding workpieces. high. [0003] Taking the precision machining of microprism reflective arrays as an example, the existing processing methods mainly include pin clustering method, lamination method, and V-shaped groove cutting method; (1) pin clustering method: take a triangular prism whose two ends are equilateral triangles, Triangular pyramids are cut at the front end of the triangular prism, and t...

Problems solved by technology

[0005] However, the existing fly-cutting and planing methods all use a single tool, and the tool is easy to wear due to the microstructure size and cutting method, and the tool wear cannot be detected in time during the processing, which will cause waste products; Another problem caused by wear and tear is that it is impossible to cut large molds, while small molds will increase the splicing times of molds in subsequent work, which will greatly affect product quality; therefore, in order to reduce the scrap rate of mold processing and improve the final Product quality, the ability to cut large pieces of the original mold without changing the tool, is crucial for precision micro-cutting
