The utility model discloses a concrete working method as follows: solid-state capacitors are fed from a positive and negative detection station 9 on a vibration feeding tray 8, the solid-state capacitors can be screened at positive and negative detection stations, the capacitors are ensured to be fed into a detection turntable in a certain direction, and corresponding areas of a plurality of capacitor surfaces detected by the same detection station are consistent, specifically, the positive and negative detection stations are provided with a rotary clamping mechanism and a photoelectric switch because the positive and negative electrodes of a lead of the solid-state capacitors have different lengths, and the photoelectric switch distinguishes the long and short leads of the solid-state capacitors through detection so as to judge the positive and negative electrodes of the solid-state capacitors and sends corresponding commands to enable the rotary clamping mechanism to correspondingly rotate; then, the top part is rotated to a top vision detection station along with the turntable, and a vision camera 3 on the station images the top part of the solid capacitor 12 and transmits the image to a vision processing system; then, as the detection turntable 11 rotates, the solid-state capacitor 12 sequentially passes through 12 side visual detection stations, and when passing through one side visual detection station, the rotation angle of the cylindrical surface of the solid-state capacitor is 30 degrees, so that after passing through the 12 side visual detection stations, the whole cylindrical surface of the solid-state capacitor can be captured by the visual cameras of the side visual detection stations, and the images are transmitted to the visual processing system for analysis and comparison. As shown in the figure, the bottom end of the capacitor fixing seat 13 on the turntable is connected with a capacitor corner gear 14, and the capacitor corner gear 14 is meshed with a capacitor corner transmission gear 15; therefore, when the capacitor fixing seat 13 rotates along with the detection turntable 11, the capacitor fixing seat itself rotates relative to the detection turntable 11 due to the transmission between the capacitor corner gear 14 and the capacitor corner transmission gear 15, so that the capacitor fixing seat performs revolution along with the turntable and performs rotation simultaneously, and the actual rotating angle of the capacitor fixing seat 13 and the capacitor 12 is the superposed angle of the capacitor fixing seat and the capacitor; in this embodiment, the relationship between the transmission ratio of the two gears and the angle interval of each side visual detection station is designed, so that the rotation angle of the solid-state capacitor cylindrical surface is actually 30 degrees after each side visual detection station passes through one side visual detection station.
After the vision processing system receives the images input by the vision cameras of the stations, the images are compared and analyzed through an algorithm with a preset image, the surface area of the capacitor detected by each station is different and unchanged, so that each detection station has an independent image algorithm model, meanwhile, the whole vision processing system adopts a random forest method, any detection station is detected to be a defective product, the stations behind the product are not detected any more, and the system efficiency is improved; when a detection error-free signal is received, the PLC outputs an instruction to a visual camera corresponding to a next detection position of the detection station, the camera is in an awakening state after a period T, the B area of the solid capacitor is detected, and if the detection is still error-free, the other side can be analogized; and when a detection error occurs in a certain area, the capacitor can be judged to be unqualified directly, the PLC outputs an instruction to a defective product removing station, and the defective product removing station is instructed to remove the capacitor on the station after N periods T, wherein N is the number of periods required for the capacitor in the current visual detection station to rotate to the defective product removing station.
