Description

Technical Field

[0001] This utility model relates to the field of 3D vision sensor installation technology, specifically a line-scan laser 3D vision sensor installation structure. Background Technology

[0002] Line-scan laser 3D vision sensors employ laser triangulation, projecting a laser beam onto an object's surface to form a spot. A camera captures the reflected light and calculates the distance. Their accuracy depends on the laser wavelength, optical system design, and algorithm processing. Line-scan laser sensors are characterized by high precision and strong anti-interference capabilities, making them ideal for applications such as automotive weld inspection and machining monitoring, achieving micron-level accuracy. However, most line-scan laser 3D vision sensors are mounted using brackets, which often suffer from instability and limited adjustability, hindering their usability.

[0003] For example, a binocular line-scanning laser 3D vision sensor mounting structure described in patent CN218441476U includes a binocular line-scanning laser 3D vision sensor body and a mounting frame, and a height adjustment mechanism and an angle adjustment mechanism for adjusting the height and rotation angle of the binocular line-scanning laser 3D vision sensor body, respectively. The height adjustment mechanism adjusts the height of the binocular line-scanning laser 3D vision sensor body, and the angle adjustment mechanism adjusts the rotation angle of the binocular line-scanning laser 3D vision sensor body. However, during the adjustment process, springs are required for limiting the movement, but the springs are not restricted. This causes the springs to vibrate when the device is subjected to vibration, resulting in significant impact on the binocular line-scanning laser 3D vision sensor body, causing continuous vibration until the springs stop vibrating. Furthermore, during the adjustment process, the tilt angle of the binocular line-scanning laser 3D vision sensor body cannot be adjusted; it can only be viewed at eye level, reducing the practicality of the device.

[0004] Based on this, a line-scanning laser 3D vision sensor mounting structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-3 As shown, a line-scan laser 3D vision sensor mounting structure includes a mounting frame 1, a support plate 11 fixedly connected to the bottom end of the mounting frame 1, an adjustment mechanism 2 provided at the top of the mounting frame 1, a rotation mechanism 3 provided at the bottom end of the adjustment mechanism 2, and a tilting mechanism 4 provided at the bottom end of the rotation mechanism 3.

[0026] In this embodiment, the position of the visual sensor body 5 in the horizontal direction can be adjusted by the adjustment mechanism 2, the visual sensor body 5 can be rotated by the rotation mechanism 3 to change the orientation of the visual sensor body 5, and the tilting mechanism 4 can change the tilt angle of the visual sensor body 5, so that the visual sensor body 5 can scan a larger range.

[0027] In an optional embodiment, the adjustment mechanism 2 includes a threaded rod 21, the outer wall of which is rotatably connected to the inner wall of the mounting frame 1. A mounting block 22 is threadedly connected to the outer wall of the threaded rod 21, and the outer wall of the mounting block 22 is slidably connected to the inner wall of the mounting frame 1. By rotating the threaded rod 21, the mounting block 22 moves on the outer wall of the threaded rod 21. The mounting block 22 drives the rotation mechanism 3 and the tilting mechanism 4 to move, thereby driving the vision sensor body 5 to move synchronously and changing the horizontal position of the vision sensor body 5.

[0028] In an optional embodiment, the mounting block 22 is rectangular in shape, and the inner wall of the mounting bracket 1 is provided with a groove that matches the shape of the mounting block 22. The cooperation between the mounting block 22 and the groove ensures that when the threaded rod 21 rotates, it will not drive the mounting block 22 to rotate, but will instead cause the mounting block 22 to translate.

[0029] In an optional embodiment, the rotating mechanism 3 includes a fixed block 31, the top end of which is fixedly connected to the bottom end of the mounting block 22. A fixed frame 33 is fixedly connected to the outer wall of the fixed block 31, and a rotating rod 34 is rotatably connected to the inner wall of the fixed frame 33. A worm gear 35 is fixedly connected to the outer wall of the rotating rod 34, and a worm wheel 36 meshes with the outer wall of the worm gear 35. A first rotating shaft 37 is fixedly connected to the axis of the worm wheel 36. The outer wall of the first rotating shaft 37 is rotatably connected to the inner wall of the fixed block 31, and a mounting plate 38 is fixedly connected to the bottom end of the first rotating shaft 37. By rotating the rotating rod 34, the worm gear 35 is driven to rotate, which in turn drives the worm wheel 36 to rotate. The worm wheel 36 drives the first rotating shaft 37 to rotate synchronously, which in turn drives the mounting plate 38 and the connecting plate 41 to rotate, thereby driving the vision sensor body 5 to rotate synchronously and changing the orientation of the vision sensor body 5.

[0030] In an optional embodiment, a limiting ring 32 is fixedly connected to the bottom end of the fixing block 31. The outer wall of the limiting ring 32 is slidably connected to a groove opened on the outer wall of the mounting plate 38. The limiting ring 32 is T-shaped, and the groove opened on the outer wall of the mounting plate 38 is adapted to the shape of the limiting ring 32. When the mounting plate 38 rotates, the limiting ring 32 slides in the groove opened on the outer wall of the mounting plate 38. The limiting ring 32 supports and limits the mounting plate 38, preventing the mounting plate 38 from jamming due to excessive friction caused by gravity when rotating.

[0031] In an optional embodiment, the tilting mechanism 4 includes a connecting plate 41, the top end of which is fixedly connected to the bottom end of the mounting plate 38. A second rotating shaft 43 is rotatably connected to the inner wall of the connecting plate 41. A connecting block 42 is fixedly connected to the outer wall of the second rotating shaft 43. A vision sensor body 5 is fixedly connected to the bottom end of the connecting block 42. A gear 44 is fixedly connected to the outer wall of the second rotating shaft 43. An arc-shaped locking tooth 45 meshes with the outer wall of the gear 44. A pull rod 46 is fixedly connected to the top end of the arc-shaped locking tooth 45. The outer wall of the pull rod 46 slides through a guide hole provided on the connecting plate 41. Pulling the pull rod 46 causes the arc-shaped locking tooth 45 to move upward, so that the teeth of the arc-shaped locking tooth 45 no longer mesh with the teeth of the gear 44. Then, the vision sensor body 5 can be rotated, causing the connecting block 42 and the second rotating shaft 43 to rotate, and the vision sensor body 5 is rotated to a suitable angle.

[0032] In an optional embodiment, a slider 47 is fixedly connected to the outer wall of the arc-shaped locking tooth 45. The outer wall of the slider 47 is slidably connected to the inner wall of the connecting plate 41. A guide rod 48 is sleeved on the inner wall of the slider 47. The end of the guide rod 48 is fixedly connected to the inner wall of the connecting plate 41. A spring 49 is sleeved on the outer wall of the guide rod 48. One end of the spring 49 is fixedly connected to the inner wall of the connecting plate 41, and the other end is fixedly connected to the outer wall of the slider 47. When the arc-shaped locking tooth 45 moves with the pull rod 46, it drives the slider 47 to slide on the outer wall of the guide rod 48, causing the spring 49 to contract. Subsequently, the pull rod 46 is released. Under the action of the spring 49, the teeth of the arc-shaped locking tooth 45 mesh with the teeth of the gear 44 again, thereby restricting the second rotating shaft 43 so that the second rotating shaft 43 can no longer rotate, keeping the visual sensor body 5 at a specified tilt angle, which facilitates its scanning and recording of objects.

[0033] The above embodiment discloses a line-scan laser 3D vision sensor mounting structure. By rotating the threaded rod 21, the mounting block 22 moves on the outer wall of the threaded rod 21. The mounting block 22 drives the rotating mechanism 3 and the tilting mechanism 4 to move, thereby causing the vision sensor body 5 to move synchronously, changing the horizontal position of the vision sensor body 5. Then, by rotating the rotating rod 34, the worm gear 35 rotates, causing the worm gear 35 to drive the worm wheel 36 to rotate. The worm wheel 36 drives the first rotating shaft 37 to rotate synchronously, causing the first rotating shaft 37 to drive the mounting plate 38 and the connecting plate 41 to rotate, thereby causing the vision sensor body 5 to rotate synchronously, changing the orientation of the vision sensor body 5. Furthermore, when the scene requires adjustment of the tilt angle of the vision sensor body 5, pulling the pull rod 46 causes the arc-shaped locking teeth 45 to move upwards, causing the arc-shaped locking teeth 45 to... The sliding block 47 slides on the outer wall of the guide rod 48, causing the spring 49 to contract and the teeth of the arc-shaped locking teeth 45 to no longer mesh with the teeth of the gear 44. Then, the vision sensor body 5 can be rotated, driving the connecting block 42 and the second rotating shaft 43 to rotate. When it reaches a suitable angle, rotation stops, and the pull rod 46 is released. Under the action of the spring 49, the teeth of the arc-shaped locking teeth 45 re-engage with the teeth of the gear 44, thus restricting the second rotating shaft 43 and preventing it from rotating further. This keeps the vision sensor body 5 at a specified tilt angle, facilitating its scanning and recording of objects. In summary, the adjustment mechanism 2 allows for horizontal translation of the vision sensor body 5; the rotation mechanism 3 allows for rotation of the vision sensor body 5 to change its orientation; and the tilt mechanism 4 allows for adjustment of the pitch angle of the vision sensor body 5. These combined adjustment functions significantly expand the effective scanning range of the vision sensor body 5.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
