| 摘要 |
The invention relates to a device (22) for evaluating an image (20), produced on a carrier material (8) by the spot welding of a weld spot (19) using an optical image detection unit (23), comprising a camera (24) consisting at least of a detection means (25) and a lens (26). To provide an evaluating device (22) with which the optical quality examination of spot welded joints can be improved, the image detection unit (23) has an illuminating means (27) with a diffuser (28) for the diffuse and homogeneous illumination of the image (20) of the spot weld on the carrier material (8). The invention also relates to a welding tool (1) for a spot welding unit, in particular a welding gun (2), having an evaluating device (22) for analyzing an image (20) of a spot weld (19) on a carrier material (8). |
