Description

Technical Field

[0001] This utility model relates to the field of lens barrel assembly technology, and in particular to a robotic arm. Background Technology

[0002] The telescope tube is a commonly used optical instrument, and its market demand in fields such as astronomy, security, and automobiles is increasing day by day. It is also an indispensable component in machine vision systems.

[0003] When assembling the lens barrel components with the glass lens, a robotic arm is needed to clamp and fix the lens barrel. However, because the outer wall of the lens barrel is curved, the lens barrel is prone to slipping between itself and the robotic arm, and the lens barrel is easy to slip off the robotic arm. As a result, the robotic arm has a poor clamping effect on the lens barrel. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the outer wall of the lens barrel is curved, making it easy for the lens barrel to slip between itself and the robotic arm, causing the lens barrel to easily slip off the robotic arm, and resulting in poor gripping effect of the robotic arm on the lens barrel. Therefore, this invention proposes a robotic arm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a robotic arm, including a mounting plate, wherein:

[0007] Both sides of the mounting plate are provided with through holes, and a rotating plate is rotatably connected to each of the through holes. A drive mechanism for rotating the rotating plate is connected to the mounting plate, and a clamping member is connected to the upper end of each rotating plate.

[0008] The clamping component includes a fixed base, which is connected to the rotating plate by a fixing bolt. A connecting block is fixedly connected to the fixed base, and a ball is connected to both sides of one end of the connecting block.

[0009] Preferably, the driving mechanism includes a movable plate with a threaded hole. A driving component is rotatably connected to the bottom end of the mounting plate, and the driving component cooperates with the threaded hole. Both ends of the movable plate are rotatably connected to connecting plates, and one end of each connecting plate is rotatably connected to a different rotating plate.

[0010] Preferably, the driving component is a threaded rod.

[0011] Preferably, the sphere is a plastic sphere.

[0012] Preferably, the sphere is fitted with an anti-slip sleeve.

[0013] The robotic arm proposed in this utility model has the following advantages:

[0014] The lens barrel is positioned between four spheres, all of which move towards the lens barrel. After contacting the lens barrel, the four spheres compress it. All four spheres make point-to-surface contact with the lens barrel, and they contact the lens barrel from different directions, thus compressing and fixing the lens barrel at four positions. Because of the point-to-surface contact with the lens barrel and the fact that different spheres contact the lens barrel from different directions, the lens barrel is less likely to fall off when it is clamped and fixed, thus improving the clamping effect of the lens barrel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 A robotic arm includes a mounting plate 1, wherein:

[0023] Both sides of the mounting plate 1 are provided with through holes 2, and a rotating plate 3 is rotatably connected to each through hole 2. The mounting plate 1 is connected with a drive mechanism 4 for driving the rotating plate 3 to rotate, and a clamping piece 5 is connected to the upper end of each rotating plate 3.

[0024] The clamping component 5 includes a fixed base 51, which is connected to the rotating plate 3 by a fixing bolt 52. A connecting block 53 is fixedly connected to the fixed base 51. A ball 54 is connected to both sides of one end of the connecting block 53. The ball 54 is a plastic ball and an anti-slip sleeve is fitted on the ball 54. The anti-slip sleeve is a rubber sleeve.

[0025] Working process: When clamping the lens barrel, the drive mechanism 4 pushes the two rotating plates 3 to rotate in opposite directions. Each rotating plate 3 drives the fixed seat 51 to rotate, each fixed seat 51 drives the connecting block 53 to rotate, and each connecting block 53 drives the two balls 54 to rotate. The balls 54 rotate towards the lens barrel, and the lens barrel is located between the four balls 54. The four balls 54 move towards the lens barrel and squeeze it after contacting it. The four balls 54 are in point-to-surface contact with the lens barrel. The four balls 54 contact the lens barrel from different directions, squeezing and fixing the lens barrel at four positions. Because of the point-to-surface contact with the lens barrel and the different balls 54 contacting the lens barrel from different directions, the lens barrel is less likely to fall off when clamping and fixing it, thus improving the clamping effect of the lens barrel.

[0026] Example 2

[0027] Reference Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the driving mechanism 4 includes a movable plate 41 with a threaded hole. The bottom end of the mounting plate 1 is rotatably connected to a driving member 42, which is a threaded rod that cooperates with the threaded hole. Both ends of the movable plate 41 are rotatably connected to connecting plates 43. One end of each connecting plate 43 is rotatably connected to a different rotating plate 3. When the rotating plate 3 is pushed to rotate and clamp the lens barrel, the driving member 42 is rotated. After the driving member 42 rotates, the movable plate 41 moves downward. After the movable plate 41 moves downward, it pulls the connecting plate 43. After the connecting plate 43 is pulled, it pushes the rotating plate 3 outward, causing the upper end of the rotating plate 3 to rotate towards the lens barrel.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
