Problems solved by technology
However, the 2D image information of the welding part of the welding product can only reflect information such as the shape and size of the two-dimensional projected contour of the welding part of the welding product, and cannot reflect information such as the three-dimensional shape and size of the welding part of the welding product. Therefore, this technical scheme of judging whether the welding quality is qualified or not based on 2D image information is still prone to misjudgment, which reduces the accuracy of judgment

The invention discloses a welding quality inspection platform, comprising: a 2D image acquisition device, adapted to acquire a 2D image of a welding part of a welded product to be inspected; a 3D image acquisition device, adapted to obtain the welded part of a welded product to be inspected 3D image; and a judging device adapted to judge whether the welding quality is qualified or not according to the obtained 2D image and 3D image of the welding part of the welding product. In each embodiment of the present invention, whether the welding quality of the welding product is qualified is judged according to the 2D image information and the 3D image information of the welding part of the welding product, thereby improving the accuracy of judgment.
Description
technical field [0001] The invention relates to a welding quality detection platform. Background technique [0002] In the prior art, human eyes are generally used to judge whether the welding quality of the welding product is qualified or not. However, the error probability of human judgment is very high, and the efficiency is also very low. Therefore, in recent years, a technical solution for judging whether the welding quality of welding products is qualified by machine vision has been proposed. In the prior art, a 2D (two-dimensional) camera is generally used to take a 2D image of the welded part (solder spot) of the welded product to be detected, and then the computer judges the welding position according to the 2D image information of the welded part of the welded product captured. Whether the quality is qualified. However, the 2D image information of the welding part of the welding product can only reflect information such as the shape and size of the two-dimension...
