Embodiment Construction

[0012] The electronic component inspection system and inspection method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Please refer to figure 1 In a preferred embodiment of the present invention, the electronic component inspection system 100 is used to check whether the polarity of the electronic component in the circuit board is reversed. The electronic component inspection system 100 includes a setting module 10, a storage module 20, an image acquisition module 30, a comparison module 40, and a processing module 50.

[0014] The setting module 10 is used to receive a sample picture of a circuit board uploaded by a user through an input unit, where the sample picture of the circuit board includes a coordinate axis, and each electronic component on the circuit board corresponds to a coordinate value. The setting module 10 is also used to set the electronic component selected by the user as an electronic co...

Abstract

The invention provides an electronic component inspection system which comprises a setting module used for a user to set an electronic component of which the polarity needs to be inspected in a reference sample picture, an image acquisition module used for acquiring an image of a to-be-inspected circuit board of an electronic component of which the polarity is to be inspected, a comparison module used for carrying out comparison to see whether the pixel color value of the electronic component in the reference sample picture is the same with the pixel color value of an electronic component in the same position in the image of the to-be-inspected circuit board, and a processing module used for generating prompting information for prompting wrong installation of the electronic component in terms of polarity when the comparison module determines that the two pixel color values are different. The invention further provides an electronic component inspection method. According to the electronic component inspection system and the electronic component inspection method of the invention, whether an electronic component is correctly installed in terms of polarity is automatically judged through an image comparison method, no manual inspection is needed, and a lot of time and manpower are saved.

Description

Technical field [0001] The invention relates to an electronic component inspection system and an inspection method for checking whether electronic components are installed correctly when producing circuit boards. Background technique [0002] In the production of motherboards or other circuit boards of electronic devices, many electronic components used are polarized, such as electrolytic capacitors, diodes, etc. Once these electronic components are reversed during soldering to the circuit board, the entire circuit will be affected. The board has a serious impact, so it is necessary to manually check whether the polarity of these electronic components is reversed during the production of the circuit board. However, the manual inspection method requires a lot of time and manpower. Summary of the invention [0003] In view of this, it is necessary to provide an electronic component inspection system and inspection method for checking whether the polarity of the electronic component...
