DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0035] Please refer to Figure 1 and 2 The present application provides a multi-axis adjusting device for a visual module, which comprises a visual module 100, a first adjusting assembly 200, a rotating mechanism 210 and a linear mechanism 220. The rotating mechanism 210 and the linear mechanism 220 are respectively used for adjusting the position of the visual module 100 in a first direction (F1 in the drawing) and a second direction (F2 in the drawing). One end of the rotating mechanism 210 is connected with the visual module 100, and the other end is connected with the linear mechanism 220.

[0036] The second adjusting assembly 300 is in an annular structure, and the linear mechanism 220 is arranged on the second adjusting assembly 300 and can move along a third direction (F3 in the drawing) on the second adjusting assembly 300.

[0037] The third adjusting assembly 400 is arranged outside the second adjusting assembly 300 and connected with the second adjusting assembly 300. The second adjusting assembly 300 can move in a fourth direction (i.e. the F4 direction shown in the figure) along the third adjusting assembly 400.

[0038] The first adjusting assembly 200, the second adjusting assembly 300 and the third adjusting assembly 400 can completely cover the object to be detected, realize the omnibearing image feature collection of the object to be detected, and collect the image features of the specified position of the object to be detected along the specified path according to the requirement. The image feature collection work of the object to be detected with different shapes can be realized in a single station, and the efficiency is greatly improved.

[0039] Specifically, when the object to be detected is a regular object, the feature collection can be realized by the cooperation of the first adjusting assembly 200 and the second adjusting assembly 300. When the object to be detected is an irregular object, the visual module 100 needs to be in the posture of directly facing the irregular part to collect the features, so that the complete image features can be obtained. When the distance between the visual module 100 and the object to be detected needs to be adjusted, the visual module 100 can be quickly adjusted by pushing the visual module 100 to move in the second direction through the linear mechanism 220. When the features of the object to be detected along the third direction need to be collected, the visual module 100 can be quickly adjusted by driving the visual module 100 to move along the third direction through the second adjusting assembly 300. When the features of the object to be detected along the fourth direction need to be collected, the visual module 100 can be quickly adjusted by driving the visual module 100 to move along the fourth direction through the third adjusting assembly 400, so as to realize the omnibearing image feature collection of the object to be detected.
