[0001] The present invention relates to the technical field of automatic optical inspection (AOI), and in particular to a surface inspection system for a foil-like object. Background Art

[0002] Aluminum foil is a multi-purpose electronic aluminum foil and has been widely used in the manufacture of various electronic components. For example, electronic aluminum foil is used to manufacture electrolytic capacitors.

[0003] It should be known that electrolytic capacitors are used to store electric charge, and electronic aluminum foil is used as the electrode material of electrolytic capacitors, and its surface area is directly related to the charge storage capacity of electrolytic capacitors. At present, the processes used to increase the surface area of ​​electronic aluminum foil include corrosion and formation, wherein the corrosion process is used to make high-purity aluminum foil receive electrochemical corrosion in a specific solution, thereby forming a microscopic rough structure containing a large number of microscopic holes on the surface of the aluminum foil. Afterwards, the formation process uses electrochemical treatment to form a dense aluminum oxide film on the surface of the aluminum foil with a microscopic rough structure, thereby forming aluminum formed foil (Formed Alfoil).

[0004] In the process of continuously and batch-wise mass production of aluminum foil (i.e., electronic aluminum foil) using automated production lines, raw materials, equipment status, environmental factors, etc. may cause the microscopic roughness structure to change in different forms, thereby affecting the specific surface area and specific volume of the final aluminum foil. Therefore, in the production and development of electronic aluminum foil, in order to analyze the reasons for the changes in specific surface area and / or specific volume, it is necessary to conduct online real-time observation of the microscopic morphology of the electronic aluminum foil.

[0005] In view of this, the inventor of the present invention has made great efforts to study and invent, and finally developed a surface inspection system for a foil-like object of the present invention. Summary of the invention

[0008] In addition, the first box and the second box are each provided with at least one insulating partition, and the internal metal parts near the top opening and / or the bottom opening are covered with an insulating protective layer.
