Quadratic element optical measuring device capable of continuously conveying objects to be measured

Abstract

The invention discloses a quadratic element optical measuring device capable of continuously conveying objects to be measured, which can be used for continuously measuring a plurality of conveyed objects to be measured. The quadratic element optical measuring device comprises two image scanners, at least two conveyers, one steering transport mechanism and an image processor. The two image scanners are fixed at positions through which conveying belts of the at least two conveyors pass respectively, and retrieve images respectively along two approximately mutually vertical size directions on each object to be measured. The steering conveying transport mechanism steers the plurality of the objects to be measured respectively, and continuously conveys the objects to be measured between the at least two conveyers. The image processor receives image data of the two image scanners, and synthesizes the image data to obtain a two-dimensional image of each object to be measured so as to execute a geometric dimension measurement, thereby obtaining the effects of reduced cost, high unit time output and accurate measurement.

Description

technical field [0001] The present invention relates to a secondary optical measuring device capable of continuously conveying objects to be measured, in particular to a secondary optical measuring device capable of continuously conveying and measuring objects to be measured. Background technique [0002] Printed circuit boards are the main components of electronics, computers, and communications products. In order to adapt to the light, thin, short, and small product characteristics in the consumer market, and under the catalysis of high-density and high-reliability requirements, advanced printed circuit boards In the current development trend, blind hole (via) and buried hole technologies are mostly used. This kind of printed circuit board with blind holes and buried holes uses blind holes to connect the wiring boards of the inner layers to the wiring on the surface. It does not need to penetrate the entire board and waste the layout space of other layers of wiring boards....

AI Technical Summary

Problems solved by technology

[0006] The biggest problem with the aforementioned optical measurement device 10 is that the objects to be measured 80 need to be fixed on the carrying fixed platform 14 one by one, and then removed from the carrying fixed platform 14 one by one after measurement, so the time for waiting for measurement or preparation operations will be delayed. long, other conventional optical measurement devices suffer from similar difficulties

In addition, if the automatic retractable board system is used, the required volume of the equipment is relatively large and the design is complicated

Obviously, the traditional optical measurement device 10 cannot meet the requirement of high output per unit time, and even cause a bottleneck for rapid mass production detection

Secondly, it needs to rely on high-precision three-axis (X, Y, Z) movement, and its cost is relatively high
