The application discloses a kind of electronic components appearance detection device, it is related to
visual inspection technical field, including: rack, it is set on the strip chain for conveying
diode;Driving mechanism, it includes variable frequency motor, first synchronous belt and driving spindle, driving spindle rotatably installed on rack, the output end of variable frequency motor is driven driving spindle rotation by first synchronous belt;Feeding mechanism, it is set with strip chain one end;Lead straight mechanism, it includes lead straight frame, lead straight wheel and second speed
reducer;Cylindrical surface detection mechanism, it is used to carry out
visual inspection to the cylindrical surface of
diode;End surface detection mechanism, it is used to carry out
visual inspection to the end surface of
diode;Discharging mechanism.The application compared with prior art, solve the problem that appearance detection mechanism and lead straight mechanism are not realized organic combination in existing diode appearance detection device, insufficient integration.
