Laser adjusting device

Abstract

The invention discloses a laser adjusting device. The laser adjusting device comprises a support seat, a Y-direction fine adjustment mechanism, a Z-direction fine adjustment mechanism, an X-directionfine adjustment mechanism and an installation seat, wherein the Y-direction fine adjustment mechanism, the Z-direction fine adjustment mechanism and the X-direction fine adjustment mechanism are sequentially arranged; the Y-direction fine adjustment mechanism comprises a first fixing seat, a first sliding block, a first differential head, a first elastic element and a first locking structure; thefirst fixing seat is mounted on the support seat; the first sliding block is mounted on the first fixing seat; a screw rod of the first differential head abuts against the first sliding block, and thescrew rod of the first differential head pushes the first sliding block to move in a first direction when extending out; the first elastic element is used for providing elastic stress which can causethe first sliding block to move in a second direction; the first direction and the second direction are opposite and are both parallel to a Y direction; the first locking structure is used for fixingthe first sliding block on the first fixing seat; and the installation seat is used for install a laser. According to the laser adjusting device, position change values of the laser in X, Y and Z directions are directly obtained so that design of multiple 3D cameras can be achieved.

Description

technical field [0001] The invention relates to an adjustment device, in particular to a laser adjustment device. Background technique [0002] At present, in the application of domestic industrial 3D vision technology, 3D cameras are used to obtain three-dimensional images of objects. When in use, the 3D camera forms a triangular relationship with the measured object through its internal plane camera and internal laser. After that, the laser irradiates structured light On the object to be detected, the planar camera receives the structured light reflected by the object to be detected to obtain a 3D image; the quality of the 3D image is determined by the positional relationship between the laser and the planar camera, and the position between the laser and the planar camera After the relationship is fixed, it can only obtain a clear 3D image of one item. [0003] Currently, when designing a 3D camera, an adjustment device is required, which can fix the laser and the plane c...

Problems solved by technology

[0003] Currently, when designing a 3D camera, an adjustment device is required, which can fix the laser and the plane camera, and adjust the positions of the fixed laser and the camera, so as to simulate the laser and the laser inside the various 3D cameras for different items. The positional relationship between the plane cameras, that is, to build a 3D analog camera; however, when detecting different items, after replacing the camera and the laser, the position of the camera and the laser needs to be readjusted. However, the existing adjustment device is in After adjusting the position of the laser, it is impossible to directly confirm how the current position after adjustment changes from the position before adjustment, so that the position of the laser after adjustment cannot be directly obtained, so that it is impossible to design a variety of 3D cameras
