Abstract: The present application discloses an appearance inspection device and an apparatus for manufacturing a battery cell. The appearance inspection device for inspecting a battery cell comprises: a first camera assembly comprising a first camera and a first light source, the first light source being configured to provide illumination to the first camera, and the first camera being configured to acquire images of a first surface of the battery cell when the first surface is covered by an insulating layer; and a second camera assembly comprising a second camera and a second light source, the second light source being configured to provide illumination to the second camera, and the second camera being configured to acquire images of the first surface when at least a partial region of the first surface is not covered by the insulating layer. According to the technical solutions provided by the present application, the versatility of the appearance inspection device can be improved, thereby improving the battery manufacturing efficiency.

Abstract: An optical detection device includes a detection workspace, a first image acquisition device, a second image acquisition device, a detection light source, and a conveyor. The detection workspace is configured to hold a target workpiece under detection. The first image acquisition device is configured to acquire an image of the target workpiece along a first direction. The second image acquisition device is configured to acquire an image of the target workpiece along a second direction different from the first direction. The detection light source is configured to provide detection light for the first image acquisition device and the second image acquisition device. The conveyor is configured to convey the target workpiece into or out of the detection workspace. An optical axis of at least a part of the detection light provided by the detection light source is coaxial with an optical axis of the first image acquisition device.
