Abstract

PURPOSE:To accurately detect the coating condition of a seal material and enable judgement as to acceptance or rejection thereof by providing an image pickup means, an arithmetic means and a judgement means. CONSTITUTION:A TV camera 3 picks up the crown part of a cell 1 as a seal material coated surface, and the video signal thereof is inputted to an image processing part 5 wherein an image is processed. The image processing part 5 comprises an arithmetic part 9 for dissolving the video signal into a plurality of picture elements for the division thereof into bright and dark field portions, and operating the ratio of the division, a data setting part 10 for storing a ratio of brightness to darkness in the standard cell 1, a comparison part 11 for comparing the operation result of the arithmetic part 9 with the data in the setting part 10 for making judgement as to whether the comparison result is within a set range, and a monitor TV 12, respectively. Furthermore, when the comparison part 11 judges heat the result is unacceptable, the judgement output therefrom actuates a discharge mechanism 7 and in other cases, the cell 1 is carried on a line 2 to a next process.

Table (Effects of the Invention) As explained in detail through the embodiments above, in the sealing material application determination device for a battery according to the present invention,
By using a different color scheme for the sealant applied to the other parts, it is possible to contrast the brightness and darkness with the other parts as the background.The battery surface is imaged, and the area of the obtained image data relative to the background can be compared. This is because it is possible to determine whether the area of the detection part, that is, the area of the sealing material, is within the upper and lower limits of the application area for standard batteries by calculating ε and comparing it with that of standard data. , the reliability of discrimination has increased compared to any of the conventional inspection methods, and since it is only necessary to install a small-scale device on the existing line, there is no significant increase in equipment costs, and the inspection itself can be automated. .
