Description

Technical Field

[0001] This utility model relates to the field of detection and positioning mechanism technology, and in particular to a 3D vision detection and positioning mechanism. Background Technology

[0002] 3D vision inspection can perform non-contact, high-precision measurement and analysis of the size, shape, and surface defects of objects. However, the position of its inspection head is mostly fixed, which has certain limitations when the object to be inspected is large. Furthermore, adjusting the position of the inspection head is inconvenient, thus affecting the positioning effect of 3D vision inspection. To address this, the authorized public account CN219776775U discloses "a 3D vision inspection positioning adjustment mechanism". This solution involves contacting the mounting base with the inspection plate, then releasing the pressure plate to make the clamping plate engage with the clamping slot, thereby quickly mounting the inspection head on the inspection plate and adjusting the lateral position of the inspection head, which facilitates the inspection of larger items.

[0003] However, in this scheme, the detection head can only scan the upper surface of the object and cannot adjust the scanning angle of the detection head to scan the oblique side of the object, which affects the scanning detection data. Therefore, a 3D vision detection and positioning mechanism is proposed. Utility Model Content
