Apparatus and method for counting the number of image-type boards

Abstract

The invention discloses an image board quantity counting device and method, and the image board quantity counting method connects an image capturing module, a distance measuring module and a display through a processor. The image capturing module captures first image information and second image information of at least one board to be measured respectively at close and far distances, the distance measuring module acquires the close and far distance information, a piece of thickness information of the second image information at the close distance is converted into another piece of thickness information at the far distance through the processor, and then thickness information of the first image information at the far distance and the thickness information of the second image information at the far distance are subjected to a proportional operation to generate a piece of quantity information which is displayed directly by the display. The real-time operation of the image and distance information quickly provides accurate quantity information, thereby improving the ease of use.

Description

technical field [0001] The invention relates to a counting device, in particular to an image-type board quantity counting device and method. Background technique [0002] The development of science and technology is changing with each passing day. In the existing technology, substrate manufacturers produce printed circuit boards, optical discs and chips, etc., which are usually produced in large quantities. Therefore, they need to count the quantity every time they enter and exit each work station, so as to facilitate the statistics of products. The loss rate generated in the production process is calculated one by one by manpower in the early way of counting the substrates, but this kind of counting method is not only time-consuming but also prone to errors due to human negligence. [0003] For example, No. I455046 "counting device and counting method" (hereinafter referred to as the previous case) of Taiwan's invention patent right in China, it includes a light source, a s...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above-mentioned prior art that the early method of counting the substrates by human eyes is prone to error and time-consuming, although the prior art can receive the optical signal (such as image signal) for the processing mechanism to perform counting processing, which can save manpower and time-consuming, but the result of counting only by the sensor picking up the signal is still susceptible to environmental influences and the influence of the position of the sensor or the board It is easy to produce errors, so for manufacturers, it is indeed necessary to further propose a solution
