Specifically, in the photo recognition step, a template image comparison method is adopted to detect the metal area photo, a deep learning method is adopted to detect the plastic area photo, the size of the position detection photo is detected, whether the photo is defective or not is comprehensively judged by combining a template comparison result and a deep learning judgment result, and a result signal is sent to a control system after the result is obtained. More specifically, the method for identifying whether the defect exists in the collected photo can refer to the detection method in the prior art, such as the application of the chinese utility model with the application number of CN201910044517.3 and the name of "system and method for detecting physical defect of lithium battery pole piece in die cutting machine, electronic device and storage medium", which discloses how to adopt devices such as linear scanning CCD, area array CCD, industrial personal computer, encoder, etc. to automatically detect the physical defect on the surface of the lithium battery pole piece and the size of the pole piece. From this, combine the detection method that prior art disclosed, the utility model discloses a connector defect detection method can realize the automatic identification defect.

To sum up, the utility model discloses set up the defect detection station, realize on a station alright with the completion to shooing in connector metal area and plastics district, and need not put and go the operation on two stations. The utility model provides a method has realized the automatic identification defect, and has overcome the mode that current detection method leaned on human eye discernment. Therefore, the connector can be subjected to integrated visual detection, the automation degree is favorably improved, and the working efficiency and the detection precision are higher.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
