Description

Precise measuring device capable of quickly holding tiny items

The present invention relates to a measuring device, in particular to a precision measuring device capable of quickly holding small objects, which eliminates the conventional complicated detection steps and greatly improves the detection efficiency.

With the development and advancement of science and technology, the requirements for precise component surface contour and size calculation are becoming more and more urgent. With the improvement of process technology, component processing has more stringent requirements on surface flatness, line width spacing, and tolerances. , Because the surface roughness of some fine micro-elements is sufficient to influence the signal quality, or the error in the processing depth and width will affect the performance of the diffraction element. The surface measurement can be divided into two-dimensional size and three-dimensional contour measurement. Among them, the three-dimensional contour measurement is the most complicated and difficult. The measurement of three-dimensional profile in various industries is like the measurement of the shape, surface roughness, curvature and scratches of optical components, or the measurement of fiber end faces, or the measurement of the surface profile of wafers, or circuits Measurement of the thickness of the tin on the board, or the surface roughness of the components.

At present, for the measurement of precision machining parts in the industry, if the production capacity is large, it must rely on the optical quick screening machine to measure. However, due to the fast speed of the optical quick screening machine, the measurement accuracy is not high, and only preliminary The screening of good products after screening must also rely on manual sampling. The measurement of general precision-processed parts using manual sampling must use a variety of measurement tools, such as optical projectors, image two-dimensional measuring instruments, calipers, etc. The full-scale measurement of the workpiece can only be completed with traditional measurement tools. This not only consumes a lot of time, equipment and labor costs, but also has relatively poor measurement efficiency.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide a precision measuring device that can quickly hold small objects without the complicated detection steps in the prior art.

The secondary objective of the present invention is to provide a precise measuring device capable of quickly holding small objects that can greatly improve the detection efficiency.
