[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0030] like Figures 1 to 6As shown, an angle adjustment device for a laser sensor 8 includes a base 1, the base 1 is provided with a rotating component 2, the rotating component 2 is provided with a first angle adjustment component 3, which can drive the first angle adjustment component 3 to rotate horizontally, the second angle adjustment component 4 is provided on the first angle adjustment component, the first angle adjustment component 3 can drive the second angle adjustment component 4 to rotate, the rotating surface of the second angle adjustment component 4 is perpendicular to the rotating surface of the first angle adjustment component 3, the second angle adjustment component 4 is provided with a mounting seat 5 for mounting the laser sensor 8, the second angle adjustment component can drive the mounting seat 5 to rotate, the base 1 is provided with a spirit level 6, and the four corners of the base 1 are provided with vertically movable and adjustable support members 7.

[0031] Specifically, when the laser sensor 8 is installed on the mounting seat 5 and the angle of the laser sensor 8 needs to be adjusted, the laser sensor 8 on the mounting seat 5 can be driven to rotate horizontally by controlling the rotation component 2 to adjust the sensing direction of the laser sensor 8. The first angle adjustment component 3 can be controlled to drive the mounting seat 5 to rotate with the first angle adjustment component 3 as the axis, and the second angle adjustment component 4 can drive the mounting seat 5 to rotate. The rotatable direction of the mounting seat 5 driven by the second angle adjustment component 4 is the same as the rotatable direction of the second angle adjustment component 4 driven by the first angle adjustment component 3. By controlling the operation of the first angle adjustment component 3 and the second angle adjustment component 4, the sensing angle of the laser sensor 8 on the mounting seat 5 can be adjusted for a second time, thereby improving the adjustment freedom and flexibility of the sensing angle of the laser sensor 8. In addition, the state of the level 6 on the base 1 can be observed to determine the horizontality of the base 1. According to the horizontality of the base 1 reflected by the level 6, the support members at the corresponding positions can be manipulated to adjust the heights of the four corners of the base 1, and the base 1 can be adjusted to a horizontal state, thereby further ensuring the accuracy of the sensing angle of the laser sensor 8 and preventing one side of the base 1 from tilting and affecting the operation of the laser sensor 8.

[0032] In some embodiments of the present application, the support member 7 includes a threaded rod 71 and a support block 73. The threaded rod 71 is vertical and threadedly connected to the base 1. The threaded rod 71 has a nut portion 72, and the side of the nut is surrounded and evenly spaced with a number of protrusions. The support block 73 is installed at the lower end of the threaded rod 71. The threaded rod 71 can be rotated to adjust the distance between the support block 73 and the base 1 by screwing the nut portion 72. Specifically, when the level 6 shows that one side of the base 1 is tilted, the threaded rod 71 on that side can be screwed. Since the threaded rod 71 is threadedly matched with the base 1, the rotation of the threaded rod 71 drives the support block 73 to move up and down. By adjusting the distance between the support block 73 and the bottom of the base 1, the height of the position of the base 1 on that side is adjusted, so that the base 1 is adjusted to a horizontal state, ensuring the installation flexibility of the laser sensor 8.

[0033] In some embodiments of the present application, two level gauges 6 are provided, which are arranged on two adjacent sides of the base 1, and the two level gauges 6 are perpendicular to each other. Specifically, the two level gauges 6 are arranged on the right side and the rear side of the top of the base 1. Since the two level gauges 6 are perpendicular to each other, the overall levelness of the four sides of the base 1 can be detected, and the direction of the deflection of the base 1 can be clearly obtained, which is more convenient for the staff to adjust.

[0034] In some embodiments of the present application, the rotating assembly 2 includes a rotating disk 21, a connecting seat 22 and a driver 27. The rotating disk 21 is arranged on the base 1, and the connecting seat 22 can be rotatably installed on the rotating disk 21. An annular guide rail 24 coaxial with the connecting seat 22 is arranged on the top of the rotating disk 21. A plurality of teeth are arranged around the side of the annular guide rail 24 and evenly spaced to form an annular rack 25. A first gear 26 meshing with the annular rack 25 can be rotatably installed on the connecting seat 22. The driver 27 is connected to the first gear 26 and can drive the first gear 26 to rotate.

[0035] Specifically, the annular guide rail 24 is slidably connected to the connecting seat 22, and is used to guide and support the rotation of the connecting seat 22. The driver 27 is a small motor; the connecting seat 22 is also provided with a first housing 23, the first housing 23 covers the lower part of the connecting seat 22 and the annular guide rail 24, and the driver 27 is connected to the first housing 23. When it is necessary to adjust the sensing direction of the laser sensor 8, the driver 27 is first controlled to operate to drive the first gear 26 to rotate. Since the first gear 26 meshing with the annular rack 25 is installed on the connecting seat 22, and the annular rack 25 is fixedly connected, it can drive the connecting seat 22 to rotate, and then drive the laser sensor 8 on the mounting seat 5 to rotate, so as to achieve the purpose of adjusting the sensing direction of the laser sensor 8. In addition, the circumference of the first gear 26 is one-fifth of the circumference of the annular rack 25, which reduces the rotation speed of the connecting seat 22, drives the laser sensor 8 to rotate slowly, and is more convenient for the laser sensor 8 to be aligned with the preset sensing direction.

[0036] In some embodiments of the present application, the first angle adjustment assembly 3 includes a first rotating shaft 31, a second gear 32 and a first knob 35. The first rotating shaft 31 is rotatably installed on the connecting base 22, the second gear 32 is installed at one end of the first rotating shaft 31, the connecting base 22 is rotatably provided with a first adjusting rod 33, the first adjusting rod 33 is provided with a first adjusting gear 34 meshing with the second gear 32, and the first knob 35 is provided at the end of the first adjusting rod 33.

[0037] Specifically, when the sensing angle of the laser sensor 8 needs to be adjusted, the first adjustment rod 33 is rotated by the first knob 35. Since the first adjustment gear 34 and the second gear 32 are meshed, the first shaft 31 is driven to rotate, and then the laser sensor 8 on the mounting seat 5 is driven to rotate around the first shaft 31 as the axis, so as to achieve the purpose of adjusting the sensing angle of the laser sensor 8. In addition, the first adjustment gear 34 is smaller than the second gear 32, and the circumference of the first adjustment gear 34 is one sixth of the circumference of the second gear 32, which reduces the rotation speed of the laser sensor 8. When the second knob 46 is rotated, the laser sensor 8 can be driven to rotate slowly, which makes it easier for the laser sensor 8 to rotate to the preset sensing angle, thereby improving the adjustment accuracy.

[0038] In some embodiments of the present application, the second angle adjustment assembly 4 includes a rotating seat 41, a second rotating shaft 42, a third gear 43, a second adjusting rod 44, a second adjusting gear 45 and a second knob 46. The rotating seat 41 is installed on the first rotating shaft 31. The second rotating shaft 42 is installed on both sides of the rotating seat 41. The mounting seat 5 is connected to the second rotating shafts 42 on both sides. The rotating shaft on one side is provided with a third gear 43. The rotating seat 41 is rotatably provided with a second adjusting rod 44. The second adjusting rod 44 is provided with a second adjusting gear 45 meshing with the third gear 43. The second knob 46 is provided at the end of the second adjusting rod 44. Specifically, the second knob 46 is controlled to drive the second adjusting rod 44 to rotate, and the second adjusting gear 45 and the second knob 46 are meshed to drive the mounting seat 5 to rotate, thereby achieving the purpose of driving the laser sensor 8 on the mounting seat 5 to adjust multiple degrees of freedom. The position and sensing angle of the laser sensor 8 are changed by the first angle adjustment component 3, and then the second angle adjustment component is controlled to drive the laser sensor 8 to rotate around the second rotating shaft 42 to adjust its sensing angle, thereby improving the flexibility and freedom of angle adjustment of the laser sensor 8.

[0039] It should be noted that a second shell 47 is provided on both the rotating seat 41 and the connecting seat 22. The second shell 47 of the rotating seat 41 covers the third gear 43 and the second adjusting gear 45; the second shell 47 on the connecting seat 22 covers the second gear 32 and the second adjusting gear 45, thereby improving the aesthetics of the device and providing a certain protective effect.

[0040] In some embodiments of the present application, the mounting seat 5 is U-shaped, and a U-shaped groove 51 for accommodating the laser sensor 8 is formed on the inner side. The four corners of the U-shaped groove 51 are provided with convex strips 52, and the convex strips 52 are used to limit the laser sensor 8. Specifically, when installing the laser sensor 8, the laser sensor 8 is placed in the U-shaped groove 51. The U-shaped groove 51 limits the left and right sides and the lower side of the laser sensor 8, and the convex strips 52 limit the front and rear sides of the laser sensor 8 to prevent the laser sensor 8 from shifting during the installation process. The mounting seat 5 has four mounting holes on both sides for bolts to pass through and connect with the laser sensor 8 in the U-shaped groove 51. The bolts pass through the mounting holes to connect with the laser sensor 8, and the laser sensor 8 is fixed to the mounting seat 5 to complete the installation of the laser sensor 8.

[0041] In some embodiments of the present application, the top of the convex strips 52 is formed with an inclined surface 53 inclined inwardly. Specifically, the top of the convex strips 52 is provided with an inclined surface 53 inclined inwardly and downwardly. When the laser sensor 8 is placed in the U-shaped groove 51, the four sides of the laser sensor 8 first contact the inclined surface 53, and the inclined surface 53 is used for guidance to drive the laser sensor 8 to be placed between the four side convex strips 52, which makes it easier for the staff to install the laser sensor 8 and improves the installation efficiency.

[0042] In some embodiments of the present application, the support block 73 is detachably connected to the threaded rod 71. Specifically, when the support block 73 is worn or damaged, the support block 73 can be removed and replaced to increase the service life of the device. A threaded hole is formed at the bottom end of the threaded rod 71, and a threaded portion that cooperates with the threaded hole is formed at the top of the support block 73. The support block 73 is detachably connected to the threaded rod 71 through the cooperation of the threaded portion and the threaded hole.

[0043] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model.
