Abstract

The invention provides a floating height detection method, a detection system and a device with a storage function. The floating height detection method comprises the following steps: obtaining a to-be-detected image of a circuit board; acquiring a sub-image corresponding to a to-be-detected component on the circuit board from the to-be-detected image; comparing the sub-image with a corresponding standard image; in response to an error in the comparison exceeding a threshold, the circuit board floats. Through the design mode, whether the component floats or not can be judged according to the skew degree of the component in the image. According to the floating height detection method, a precise measuring instrument does not need to be introduced, only an image acquisition device needs to be introduced on the transmission line, an original transmission line structure does not need to be changed, the whole detection method is mainly based on software, the hardware cost is low, and updating and upgrading are convenient.

Description

technical field [0001] The application belongs to the technical field of circuit boards, and in particular relates to a floating height detection method, a detection system and a device with a storage function. Background technique [0002] It is a very important process to detect the abnormality of the circuit board before the soldering operation. Usually, whether the components on the circuit board are floating or not can be detected by manual or automatic inspection by instruments. [0003] At present, the method of using instruments to automatically check the floating height generally requires complex structural design, and requires the combination of sophisticated testing instruments, which is not universal; and usually requires the overall structure of the transmission line to be transformed, which has a great impact on the production line and cannot be used in large areas. promotion. SUMMARY OF THE INVENTION [0004] The present application provides a floating heig...
