Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an automatic positioning and focusing detection device based on machine vision detection to solve the problem that the existing automatic positioning and focusing detection device for machine vision detection cannot be moved by a single motor-driven detection structure when it is in use. It is not possible to adjust the detection structure at an appropriate position according to the needs, and it is not convenient to use. In addition, when the existing automatic positioning and focusing detection device for machine vision detection is used, it usually uses a belt drive. After a long period of use, the belt is prone to slippage , which leads to the adjustment can not be synchronized, and after a long time of use, it is prone to loosening, and there is no problem with the structure that makes it continue to tighten the transmission
