The invention relates to the technical field of plastic detection, in particular to an automatic plastic appearance detection device. The automatic plastic appearance detection device comprises a shell, a machine table, a product discharging disc, a feeding disc placing mechanism, a product carrying mechanism, a CCD appearance detection module and a qualified product placing mechanism, the machinetable is fixedly arranged in the shell, the shell is arranged on the machine table in a sleeving mode, the CCD appearance detection module is fixedly installed on the machine table, a first product transfer shaft is fixedly installed on the machine table on one side of the upstream of the CCD appearance detection module, a second product transfer shaft is fixedly installed on the machine table onone side of the downstream of the CCD appearance detection module, and the product carrying mechanism is arranged on the machine table between the first product transfer shaft and the second producttransfer shaft. By means of the structure, automatic plastic product detection is achieved, the product appearance is detected through automatic equipment, the turnover space is reduced, the turnovertime is shortened, the detection efficiency is further improved, the detection accuracy is improved and the production cost is reduced.
