Embodiment Construction

[0056] figure 1 It is a figure which shows the schematic structure of the foreign object inspection apparatus 100 which concerns on one aspect of this invention. figure 2 is a plan view of the main surface 31 of the image sensor 3 .

[0057] The foreign object inspection device 100 detects a foreign object 13 adhering to the inspection object 1 . The inspection object 1 is a separator roll body in which a separator 12 for a non-aqueous electrolyte secondary battery is wound around a core body 11 . Wherein, the inspection object 1 may also be an object formed by winding a thin film around the core body 11 other than the separator 12 for a non-aqueous electrolyte secondary battery, or may not be an object formed by winding a thin film around the core body 11. thing. The foreign matter inspection device 100 includes an electromagnetic wave generator 2 , an image sensor 3 , and an image processing device 4 .

Abstract

Provided is a foreign object inspection device and a foreign object inspection method. The foreign object inspection device to increase the efficiency of inspection and reduce the risk of a failure todetect a foreign object is provided. The foreign object inspection device includes: a moving mechanism configured to translate an inspection target; an image sensor in the form of a TDI sensor; a storage section; a pixel value computing section configured to calculate the respective second pixel values of a plurality of pixels on the basis of first pixel values; and a pixel value integrating section configured to integrate the respective second pixel values of a group of pixels belonging in a particular continuous region.

Description

technical field [0001] The present invention relates to a foreign matter inspection device and a foreign matter inspection method. Background technique [0002] Nonaqueous electrolyte secondary batteries such as lithium ion secondary batteries are widely used as batteries for personal computers, mobile phones, portable information terminals, and the like. In particular, lithium-ion secondary batteries are used to reduce CO as compared to conventional secondary batteries. 2 Attention is paid to batteries that discharge less and help save energy. [0003] Conventionally, development of a separator wound body in which a separator for a non-aqueous electrolyte secondary battery is wound around a core body has been underway. In addition, studies are being made on foreign matter inspection for detecting foreign matter adhering to the separator wound body. [0004] As an example of an inspection that can be applied to the above-mentioned foreign object inspection, the technology...
