Abstract: The present disclosure relates to a 3D scanning and appearance inspection apparatus for a cylindrical secondary battery, capable of extracting points for 3D model creation and acquiring a surface image for appearance inspection simultaneously while rotating the cylindrical secondary battery. According to the present disclosure, a construction for 3D scanning and appearance inspection for a cylindrical secondary battery can be simplified, accurate 3D data can be acquired, and accurate appearance inspection is possible.

Abstract: Disclosed is an inspection device for an appearance of a pogo pin, including: a seating portion configured to seat the pogo pin thereon; a pogo pin posture adjuster configured to adjust a posture of the pogo pin based on magnetic force by adjusting a position of a magnet placed under the seating portion; a rotation unit configured to rotate the seating portion; a coaxial aligner configured to coaxially align a rotation center of the pogo pin with the rotation unit; and at least one vision module configured to acquire images of the pogo pin seated on the seating portion. According to the disclosure, the inspection device for the appearance of the pogo pins ensures the accuracy and speed in inspecting the appearance of the pogo pin.

Abstract: The appearance inspection apparatus for a secondary battery according to the disclosure can obtain an image corresponding to an area of not less than 180 degrees of a lateral surface of the secondary battery when the secondary battery is captured at a first posture, and obtain an image corresponding to the entire lateral surface of the secondary battery when the secondary battery is captured at a second posture, thereby having an effect on significantly improving inspection speed.

Abstract: Disclosed is an appearance inspection apparatus for a secondary battery, which simultaneously obtains laterals image by picking up a plurality of secondary batteries loaded in a tray, and then simultaneously obtains top and bottom images of the secondary batteries by returning the plurality of inspected secondary batteries back to the tray and transporting the tray.

Abstract: Disclosed is an apparatus for inspecting the appearance of a can for a secondary battery, which can obtain an image of the appearance of the can for the secondary battery and determine whether there is a defect. The apparatus for inspecting the appearance of a can for a secondary battery according to the disclosure obtains lateral images of a plurality of cans at once, and generates the lateral image for one can by extracting an area where each can is captured, thereby speeding up the inspection. Further, the lateral images of the can are obtained with light emitted in various combinations, thereby having an effect on improving the accuracy in defect diagnosis.

Abstract: Disclosed are an apparatus and method for inspecting appearance of secondary batteries, in which a plurality of secondary batteries arranged in a lateral direction are rotated at a time, a photographed image obtained by a camera according to rotated angles is divided into individual image sections where the secondary batteries are respectively photographed, and an inspection image is generated by combining the individual image sections according to the photographed images of one secondary battery.
