Technical Field

[0001] This utility model relates to the field of robot vision sensor technology, and in particular to an angle adjustment mechanism for a robot vision sensor. Background Technology

[0002] In robot vision systems, the angle adjustment of vision sensors is crucial, as it directly affects the accuracy and comprehensiveness of the robot's acquisition of information about its surrounding environment.

[0003] However, most existing robot vision sensor angle adjustment mechanisms are complex in structure and cumbersome in adjustment process. Some adjustment mechanisms use multiple motors and transmission components to achieve angle adjustment, which not only increases the cost of the equipment, but also results in poor overall structural compactness. Transmission errors are prone to occur during operation, affecting the adjustment accuracy. At the same time, these complex structures are also extremely inconvenient to install and maintain, requiring professionals to spend a lot of time and effort to operate them.

[0004] Therefore, we provide an angle adjustment mechanism for a robot vision sensor. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an angle adjustment mechanism for a robot vision sensor, thus solving the problems of complex structure and inconvenient adjustment in existing robot vision sensor angle adjustment mechanisms.

[0006] In view of this, the present invention provides an angle adjustment mechanism for a robot vision sensor, including a support base, wherein a first support frame, a second support frame, a vision sensor, and a vertical adjustment component are provided on the support base;

[0007] The vertical adjustment assembly includes a rotating shaft, and the second support frame is movably mounted on the first support frame via the rotating shaft. Fixing teeth at both ends of the rotating shaft pass through both ends of the first support frame.

[0008] The vertical adjustment assembly also includes a U-shaped plate with toothed plates at both ends. The toothed plates at both ends respectively mesh with the fixed teeth at both ends of the rotating shaft. The U-shaped plate is connected to the output end of the telescopic cylinder installed on the support base.

[0010] Preferably, the vertical adjustment assembly further includes two guide pillars, which are mounted on the support base and are connected through the two ends of the horizontal transverse portion of the U-shaped plate.

[0011] Preferably, the bottom of the two guide posts is provided with a threaded structure, and the two guide posts are installed on the support base in a spiral manner.

[0013] Preferably, the upper end of the movable shaft is provided with a toothed cavity, which meshes with the transmission teeth at the output end of the drive motor.

[0014] Preferably, the connecting end of the fixing frame has a positioning hole.

[0015] Compared with the prior art, this utility model provides an angle adjustment mechanism for a robot vision sensor, which has the following advantages:

[0016] 1. Compared with existing adjustment mechanisms that use multiple motors and complex transmission components, this application achieves vertical angle adjustment of the vision sensor only through the meshing transmission of telescopic cylinder, U-shaped plate, toothed plate, rotating shaft and fixed teeth, which reduces the number of parts, simplifies the overall structural layout, and effectively reduces equipment manufacturing costs and energy consumption.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1 - Figure 4 The robot vision sensor angle adjustment mechanism in this embodiment includes: a support base 1, on which a first support frame 2, a second support frame 3, a vision sensor 4, and a vertical adjustment component 5 are provided; the vertical adjustment component 5 includes a rotating shaft 51, the second support frame 3 is movably mounted on the first support frame 2 via the rotating shaft 51, and the fixing teeth 52 at both ends of the rotating shaft 51 pass through both ends of the first support frame 2; the vertical adjustment component 5 also includes a U-shaped plate 53, the U-shaped plate 53 has toothed plates 531 at both ends, the toothed plates 531 at both ends respectively mesh with the fixing teeth 52 at both ends of the rotating shaft 51, and the U-shaped plate 53 is connected to the output end of a telescopic cylinder 54 mounted on the support base 1.

[0028] The vertical angle adjustment of the vision sensor 4 can be achieved through the meshing transmission of the telescopic cylinder 54, U-shaped plate 53, toothed plate 531, rotating shaft 51, and fixed tooth 52. Compared with the traditional adjustment mechanism with multiple motors and complex transmission components, the number of parts is reduced, and the equipment manufacturing cost and energy consumption are reduced.

[0029] In this system, by controlling the telescopic cylinder 54 to extend and retract, the U-shaped plate 53 moves. Through the meshing of the toothed plate 531 with the fixed tooth 52, the linear motion of the telescopic cylinder 54 can be converted into the stable rotation of the rotating shaft 51, thereby realizing the rapid adjustment of the vertical angle of the vision sensor 4. The operation does not require complex multi-motor coordination, thus improving the adjustment efficiency.

[0030] The first support frame 2 is provided with a mounting hole for the rotating shaft 51 to pass through, and the size of the mounting hole is adapted to the outer diameter of the rotating shaft 51.

[0031] The vertical adjustment component 5 also includes two guide posts 55, which are mounted on the support base 1 and are connected through to both ends of the horizontal part of the U-shaped plate 53.

[0032] Two guide posts 55 pass through both ends of the horizontal transverse part of the U-shaped plate 53, providing a stable guiding structure for the movement of the U-shaped plate 53. During the movement of the U-shaped plate 53 driven by the telescopic cylinder 54, the guide posts 55 can effectively limit the offset and sway of the U-shaped plate 53, avoid its displacement in the horizontal direction, and ensure that the U-shaped plate 53 moves smoothly along a fixed trajectory, thereby making the entire vertical adjustment assembly 5 operate more stably.

[0033] Among them, the bottom of the two guide posts 55 is provided with a threaded structure, and the two guide posts 55 are installed on the support base 1 in a spiral manner. The threaded structure at the bottom of the guide posts 55 facilitates their installation and removal on the support base 1.

[0034] One end of the second support frame 3 is integrally formed with an annular groove structure. A movable shaft 31 is assembled at the center of the annular groove structure. The movable shaft 31 is connected to the output end of the drive motor 6 above. The vision sensor 4 is installed at the lower end of the movable shaft 31. The drive motor 6 is installed on the side wall of the second support frame 3 through a fixing bracket 7.

[0035] The upper end of the movable shaft 31 is provided with a toothed cavity 311, which meshes with the transmission teeth at the output end of the drive motor 6.

[0036] The horizontal angle adjustment of the vision sensor 4 can be conveniently achieved by the transmission teeth at the output end of the drive motor 6 meshing with the tooth cavity 311 of the movable shaft 31.

[0037] The fixing bracket 7 has a positioning hole reserved at the connecting end.

[0038] The working principle of the above embodiments is as follows:

[0039] In use, the telescopic cylinder 54 drives the U-shaped plate 53 to move vertically on the support base 1. The toothed plates 531 at both ends of the U-shaped plate 53 move accordingly, meshing with the fixed teeth 52 at both ends of the rotating shaft 51. The movement of the toothed plates 531 causes the rotating shaft 51 to rotate. Since the second support frame 3 is movably mounted on the first support frame 2 via the rotating shaft 51, and the vision sensor 4 is mounted on the second support frame 3, the rotation of the rotating shaft 51 drives the second support frame 3 and the vision sensor 4 to achieve vertical angle adjustment until the target angle is reached, at which point the telescopic cylinder 54 stops. When the horizontal angle of the vision sensor 4 needs to be adjusted, the drive motor 6 is started. The transmission teeth at the output end of the drive motor 6 mesh with the tooth cavity 311 at the upper end of the movable shaft 31, transmitting the rotational motion of the drive motor 6 to the movable shaft 31. The movable shaft 31 rotates. Since the movable shaft 31 is mounted at the center of the annular groove structure at one end of the second support frame 3, and the vision sensor 4 is installed at the lower end of the movable shaft 31, the rotation of the movable shaft 31 drives the vision sensor 4 to adjust its horizontal angle until the target angle is reached, at which point the drive motor 6 stops running.

[0040] In this application, the telescopic cylinder 54 and the drive motor 6 are both driven by a controller. Although the controller is not shown in the accompanying drawings, its control function can be realized through PLC programming technology. Based on the actual working conditions, the user can write specific program logic in the PLC to precisely control the telescopic stroke of the telescopic cylinder 54 and the speed and direction of the drive motor 6, thereby realizing the automated and intelligent adjustment of the vertical and horizontal angles of the vision sensor 4.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
