[0035] The clamping mouth assembly 3 includes a closing ring 31 and a plurality of arc-shaped sheet bodies 32. The plurality of arc-shaped sheet bodies 32 are arranged in a circular array around the central axis of the cylinder 2. One end of the arc-shaped sheet body 32 is connected to the cylinder 2. The other end of the arc-shaped sheet body 32 extends away from the cylinder 2 along the central axis of the cylinder 2. The diameter formed by enclosing the plurality of arc-shaped sheet bodies 32 is larger than the radial specification of the cylinder 2. The closing ring 31 is movably connected to each arc-shaped sheet body 32;

[0036] The lens fixing member 5 is arranged on the base 1 and fixes an external lens.

[0037] Specifically, in this embodiment, the manipulator 1, the cylinder 2, the clamping component 3, and the base 4 are arranged in sequence from top to bottom. The base 4 is cylindrical. The central axes of the cylinder 2, the clamping component 3, the lens fixing member 5, and the light source 6 coincide. Preferably, the clamping component 3 includes three arc-shaped sheets 32. The three arc-shaped sheets 33 are arranged in a circular array around the central axis of the cylinder 2. One end of the arc-shaped sheet 32 is fixedly connected to the cylinder 2, and the other end of the arc-shaped sheet 32 is a free end extending away from the cylinder 2. The aperture formed by enclosing the free ends of the three arc-shaped sheets 32 is larger than the radial specification of the cylinder 2. This structure enables the free end of the arc-shaped sheet 32 to have a certain elasticity relative to the cylinder 2, facilitating the swing of the arc-shaped sheet 32 within a certain range. The outer surface of the arc-shaped sheet 32 is provided with an external thread, and the closing ring 31 is provided with an internal thread. The closing ring 31 is screwed onto the arc-shaped sheet 32. By rotating the closing ring 31, the closing ring 31 is fixed at different positions of the arc-shaped sheet 32, achieving the purpose of adjusting the aperture of different specifications formed by the open ends of the three arc-shaped sheets 32, meeting the purpose of clamping external retaining rings of different specifications. The working principle is as follows: Place the external lens barrel into the base 4, the lens fixing member 5 fixes the external lens, place the external lens into the lens barrel, the arc-shaped sheet 32 of the clamping component 3 clamps the external retaining ring and moves it to directly above the lens barrel, the manipulator 1 drives the cylinder 2 to move so that the clamping component 3 enters the lens barrel, the manipulator 1 drives the cylinder 2 to rotate, and the cylinder 2 synchronously drives the clamping component 3 to rotate, pressing the retaining ring against the lens barrel to complete the assembly of the lens and the lens barrel. Preferably, the clamping component 3 further includes a plurality of rods 34. The rods 34 are arranged inside the arc-shaped sheet 32, and the lower surface of the rod 34 is flush with the lower surface of the arc-shaped sheet 32. The arrangement of the rods 34 increases the contact area with the retaining ring, that is, increases the surface pressure and improves the controllability of the assembly quality. Preferably, the lens fixing member 5 includes a lens fixing driving source 51 and a plurality of clamping members 52. The plurality of clamping members 52 are arranged in a circular array. The lens fixing driving source 51 drives the clamping members 52 to move so that the clamping members 52 fix the external lens. The number of the clamping members 52 is six. The six clamping members 52 are arranged in a circular array. Each clamping member 52 inclines outward in a radial shape. When fixing the external lens barrel, place the external lens barrel into the space enclosed by the six clamping members 52. The lens fixing driving source 51 drives the six clamping members 52 to move synchronously until different apertures are formed at the intersections of the six clamping members 52 and the base 4 to clamp external lens barrels of different specifications. The light source 6 is arranged on the base 4 to assist in installing the lens. The central axis of the light source 6 coincides with the central axis formed by enclosing the plurality of clamping members 52.

[0038] By providing the manipulator 1, the cylinder 2, the clamping component 3, the base 4, the lens fixing member 5, and the light source 6, the clamping component 3 includes a closing ring 31 and a plurality of arc-shaped sheets 32. By rotating the closing ring 31, the aperture specification formed by enclosing the plurality of arc-shaped sheets 32 is adjusted to meet the purpose of clamping different retaining rings, achieving the purpose of multi-purpose use of one machine and cost reduction.

[0039] The lens fixing member 5 further includes a movable connecting member 53. The lens fixing driving source 51 drives the movable connecting member 53 to move. Each clamping member 52 is arranged on the movable connecting member 53. A plurality of clamping members 52 are arranged in a circular array. Each clamping member 52 is arranged at an angle with the movable connecting member 53. Preferably, one end of the clamping member 52 is connected to the movable connecting member 53. The lens fixing driving source 51 drives the movable connecting member 53 to move up and down, so as to drive a plurality of clamping members 52 to move up and down synchronously.

[0040] The base 4 includes an outer shell 41, a top plate 42 and a cavity 43. The top plate 42 is connected to the outer shell 41 and encloses the cavity 43. The top plate 42 is provided with an inclined hole 401. The inclined hole 401 penetrates the top plate 42 along the thickness direction of the top plate 42. The movable connecting member 53 is arranged in the cavity 43. Preferably, the outer shell 41 includes a bottom plate and side plates connected to the bottom plate. The top plate 42 is connected to the side plates. The top plate 42 and the bottom plate are spaced apart to form the cavity 43. The movable connecting member 53 is placed in the cavity 43, so as to hide the movable connecting member 53 and save space at the same time. A plurality of inclined holes 401 are processed on the top plate 42. One clamping member 53 passes through one inclined hole 401, so that the clamping member 53 slides along the inclined hole 401. The inclined hole 401 plays a guiding role for the clamping member 53 to ensure the stability of the direction of the clamping member 53 during the lifting process. The light source 6 is arranged on the top plate 42.

[0041] The manipulator 1 includes a lifting driving member 11, a rotating driving member 12 and a plurality of jaws 13. The lifting driving member 11 drives the rotating driving member 12 to move up and down. The rotating driving member 12 drives the jaws 13 to rotate. The lifting driving member 11 adopts a servo motor structure to drive the jaw driving member 12 to move up and down. The rotating driving member 12 drives the jaws 13 to rotate, so as to drive the cylinder body 2 to rotate synchronously, that is, to drive the clamping port assembly 3 to rotate.

[0042] The cylinder body 2 includes a body 21 and an annular groove 22. The annular groove 22 is recessed on the side surface of the body 21. The body 21 is a hollow cylindrical structure with upper and lower openings, which reduces the weight of the cylinder body 2. The jaws 13 protrude into the annular groove 22. The arrangement of the annular groove 22 facilitates the clamping of the cylinder body 2 by the jaws 13. Preferably, a rubber ring is installed in the annular groove 22 to increase the frictional resistance between the jaws 13 and the cylinder body 2 and achieve a sound insulation effect at the same time.

[0043] The cylinder body 2 further includes a plurality of receiving grooves 23. The annular groove 22 and the receiving grooves 23 are arranged in sequence along the height direction of the main body 21. The annular groove 22 and the receiving grooves 23 are spaced apart. The receiving grooves 23 start from the end face of the main body 21 and extend towards the other end face. One end of the arc-shaped sheet body 32 is fixed in the receiving groove 23, and the other end of the arc-shaped sheet body 32 extends out of the receiving groove 23 and extends away from the main body 21. The arrangement of the receiving grooves 23 enables the assembly of the arc-shaped sheet body 32 and the cylinder body 2 to be unified, improving the installation accuracy of the arc-shaped sheet body 32 and the cylinder body 2.

[0044] The clamping component 3 further includes an inner support member 33. The inner support member 33 is slidably connected to each arc-shaped sheet body 32. The inner support member 33 is in a ring structure. The inner support member 33 provides inner support for the plurality of arc-shaped sheet bodies 32, preventing the problem of deformation of the arc-shaped sheet bodies 32 during use, and at the same time ensuring the stability of the central axis formed by enclosing the plurality of arc-shaped sheet bodies 32, improving the use accuracy, that is, the stability of clamping the external retaining ring.

[0045] The arc-shaped sheet body 32 is provided with a limiting groove 321. The inner support member 33 is slidably connected to the limiting groove 321. The length of the limiting groove 321 is greater than the radial specification of the inner support member 33. When the closing ring 31 is rotated, the diameter formed by enclosing the plurality of arc-shaped sheet bodies 32 becomes larger or smaller, and the inner support member 33 moves up and down synchronously along the central axis of the arc-shaped sheet body 32. That is, when the diameter formed by enclosing the plurality of arc-shaped sheet bodies 32 becomes larger, the limiting groove 321 moves upward, and vice versa downward. The arrangement of the limiting groove 321 enables the swinging range of the arc-shaped sheet body 32 to be within a preset range.

[0046] Preferably, the inner support member 33 includes an outer ring body 331, an inner ring body 332 and a plurality of connecting blocks 333. The outer ring body 331 and the inner ring body 332 are spaced apart. The central axes of the outer ring body 331 and the inner ring body 332 coincide. The outer ring body 331 and the inner ring body 332 are connected by the connecting blocks 333. The arc-shaped sheet body 32 is located between the outer ring body 331 and the inner ring body 332. The arc-shaped sheet body 32 is located between two adjacent connecting blocks 332. The arrangement of the inner support member 33 further ensures the consistency of the central axis formed by enclosing the plurality of arc-shaped sheet bodies 32 during the assembly process.
