摘要： A system for finding black spots in a separator includes a winder, a rewinder that takes out and winds a separator from a rechargeable battery cell and supplies a sample of the separator; a foreign material remover that removes a foreign material from the separator; an image measurer that obtains a first image where black spots are estimated in the separator passing through the foreign material remover with a first camera and records the position of the first image; a second image measurer that selects where black spots are estimated and acquires an image of black spots and foreign material other than black spots recorded by a second camera by using the first image for the separator passing through the measurer; and a black spot sorting unit displaying the position after secondarily selecting black spots by deep learning the first image and the second image with a deep learning software.

摘要： A method of finding black spots in a separator according to an embodiment includes taking out a separator from a rechargeable battery cell; removing a foreign material of the separator surface; obtaining a first image for a portion where black spots are estimated in the separator by using a first camera and recording a position of the first image; first selecting the part where black spots are estimated by using the first image, and acquiring a second image for black spots and a foreign material other than black spots in the separator by using a second camera for the recorded position; and secondary selecting black spots by deep learning the first image and the second image with a deep learning software and then displaying the position of the black spots after.
