Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition, in particular to a data acquisition card for machine vision detection. Background Art

[0002] The visual system is to use machines to replace human eyes for measurement and judgment. The visual system refers to the use of machine vision products (i.e. image capture devices, divided into CMOS and CCD) to convert the captured target into image signals, transmit them to a dedicated image processing system, and convert them into digital signals based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the action of the equipment on site based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging. It has immeasurable value in the function of detecting defects and preventing defective products from being delivered to consumers;

[0003] However, in the existing technology, the visual circuit board cannot be cooled after it is installed, and the heat dissipation effect is poor after the circuit board is installed and fixed. It is easy to be damaged when working at a high temperature for a long time. Moreover, the visual circuit board is usually fixed on an external device. When the external device vibrates, the visual circuit board is easily damaged, thereby failing to achieve the best use effect. Utility Model Content
