A method and apparatus for spot-checking a visual inspection system are disclosed. The method includes: (210) obtaining a plurality of to-be-inspected images; (220) inspecting the plurality of to-be-inspected images to obtain defect types and / or parameters of a target object in the plurality of to-be-inspected images; and (230) confirming availability of the visual inspection system based on the defect types and / or parameters.

This utility model provides a high-efficiency bar inspection device, comprising: a feeding station and several inspection modules arranged sequentially; a feeding mechanism for sequentially feeding several bars into the feeding station; a discharging mechanism including several movable parts arranged parallel to several fixed parts and forming discharging stations between them, a qualified receiving device corresponding to each of the discharging stations, and several recycling receiving devices corresponding to the inspection modules; the discharging stations are arranged sequentially in a horizontal direction; the movable parts move to abut against the fixed parts to close the discharging station or space themselves from the fixed parts to open the discharging station; and several transfer mechanisms for sequentially moving the bars along the inspection modules and discharging stations. This ensures that the discharging station corresponding to the bar's serial number opens accurately, discharging the bar into the corresponding receiving device, thus achieving bar inspection and automatic sorting and discharging.
