Description

Technical Field

[0001] The utility model belongs to the technical field of measurement, and in particular relates to an outer diameter measuring device for changing a soft knife. Background Art

[0002] At present, common dicing machine blades are mainly divided into two types: soft blades and hard blades. Generally speaking, a circular thin-sheet grinding wheel is called a soft blade, and a grinding wheel that combines a grinding wheel with an aluminum alloy tool holder is called a hard blade. Among them, soft blades can be used for dicing and cutting various semiconductor packaging materials such as ceramics, glass, sapphire, ferrite, lithium niobate single crystal, etc., and their common specifications are mostly divided by dimensions such as outer diameter, inner diameter or thickness. When the soft blade is trimmed and cut, it is often necessary to measure the outer diameter of the trimmed soft blade to ensure that it meets the requirements. However, most of the existing measuring tools such as outside diameter micrometers or vernier calipers are used for manual measurement, and the measurement results are greatly affected by the skill level of the operator. Not only is the labor intensity high, but it is also prone to human errors, resulting in inconsistent measurement results before and after, which needs to be improved. Utility Model Content
