[0047] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. In the description of the present utility model, it should be understood that unless otherwise specified, the meaning of "a plurality of" is two or more.

[0048] A clamping mechanism for a lens barrel 3 in a specific embodiment of the present utility model. This clamping mechanism for the lens barrel 3 is adapted to carry the lens barrel 3 through a carrier 1 and can control the carrier 1 to drive the lens barrel 3 to perform pose conversion according to the required assembly position during operation, so as to adapt to the installation position requirements of lenses with different shapes and structures to be assembled on the lens barrel 3.

[0049] See Figure 1 and Figure 2 , the clamping mechanism for the lens barrel 3 includes a carrier 1 and a rotary adjustment link mechanism 2. The carrier 1 is arranged on the rotary adjustment link mechanism 2 for carrying the lens barrel 3. Since the lens barrel 3 has a special-shaped structure with multiple lens mounting positions, and each lens mounting position is located in a different orientation, during the assembly process, it is necessary to adjust the position of the lens barrel 3 according to different types of lenses to be installed to ensure that the lenses can be smoothly installed on the lens barrel 3. In addition, in order to ensure that the lenses can be stably carried by the carrier 1, a positioning structure 11 is provided on the carrier 1, and a positioning hole 32 is correspondingly opened on the lens barrel 3. The positioning structure 11 opened on the carrier 1 is inserted into the positioning hole 32 to achieve precise positioning of the carrier 1 for the lens barrel 3.

[0050] See Figure 1 and Figure 2 , a base 7 is further provided at the bottom of the rotary adjustment mechanism 2, and an angular displacement measuring table 6 capable of achieving angle adjustment is provided at the bottom of the base 7. The angular displacement measuring table 6 can achieve rotational adjustment in the X and Y directions. It should be noted that the adjustment surfaces of the angular displacement measuring table 6 in the X and Y directions are arc-shaped. Therefore, when performing adjustment movement in the X and Y directions, it should also move along the arc-shaped adjustment surface to directly adjust the positions of the rotary adjustment mechanism 2, the carrier 1, and the lens barrel 3.

[0051] The rotary adjustment link mechanism 2 is connected to the carrier 1, and the rotary adjustment link mechanism 2 has a rotary adjustment stroke in the clockwise and counterclockwise directions. In this embodiment. Therefore, the rotation of the rotary adjustment link mechanism 2 can drive the carrier 1 to rotate synchronously to adjust the deflection angle of the carrier 1 and the lens barrel 3 carried thereon.

[0052] See Figure 3, the rotation adjustment link mechanism 2 includes a first adjustment component 21. The first adjustment component 21 includes a first adjustment cylinder 211, a carrier seat fixing member 212, and a rotation conversion component 213. The first adjustment cylinder 211 has a linear movement stroke in the vertical direction. The fixing members of the carrier seat 1 are respectively arranged at both ends of the carrier seat 1. The rotation conversion component 213 is connected to both the first adjustment cylinder and the carrier seat fixing member 212 at one end. Thus, when the first adjustment cylinder 211 moves in the vertical direction, the rotation conversion component 213 can convert the linear motion generated by the first adjustment cylinder 211 into a rotational motion, so as to drive the carrier seat 1 to rotate through the first adjustment cylinder 211. And according to the linear movement stroke of the first adjustment cylinder 211, the carrier seat 1 can be driven to rotate by 0° to 90°, so as to realize the pose adjustment of the lens barrel 3 arranged on the carrier seat 1 within the 0° to 90° rotation range.

[0053] See Figure 6 , the rotation conversion component 213 includes a first conversion member 2131 and a second conversion member 2132. The first conversion member 2131 is connected to the output end of the first adjustment cylinder 211. One end of the second conversion member 2132 is connected to the first conversion member 2131 via a first rotation connecting member 2134. The other end of the second conversion member 2132 is fixedly connected to the carrier seat 1 at one end via a second rotation connecting member 2135. Thus, when the first adjustment cylinder 211 extends or retracts a set stroke, the first conversion member 2131 drives one end of the second conversion member 2132 to lift or lower via the first rotation connecting member 2134. At the same time, the other end of the second conversion member 2132 drives the carrier seat fixing member 212 to rotate clockwise or counterclockwise by a set angle via the second rotation connecting member 2135, and the deflection angle of the carrier seat 1 is controlled according to the stroke of the first adjustment cylinder 211 extending or retracting.

[0054] Specifically, one end of the second conversion member 2132 connected to the second rotating connection member 2135 is provided with a first adjustment slot hole 2136. One end of the first rotating connection member 2134 extends a fitting portion along its radial direction, and this fitting portion is adapted to move within the range defined by the first adjustment slot hole 2136. A third conversion member 2133 is further provided between the second conversion member 2132 and the carrier seat fixing member 212. A rotation limiting hole 2137 is provided on the third conversion member 2133. The second rotating connection member 2135 is adapted to pass through the rotation limiting hole 2137 and is connected to the carrier seat fixing member 212. Thus, the second rotating connection member 2135 can be restricted from moving radially through the rotation limiting hole 2137 and can only perform a rotational movement within the rotation limiting hole 2137. Therefore, through the restriction of the first rotating connection member 2134 and the second rotating connection member 2135 by the second conversion member 2132 and the third conversion member 2133, it is ensured that during the conversion process of linear motion to rotational motion, the carrier seat 1 will not have a position offset in the horizontal direction and can only generate a position deflection. Furthermore, the position accuracy during the lens assembly process is ensured, effectively guaranteeing the assembly precision.

[0055] See Figure 4 , the rotation adjustment link mechanism 2 further includes a second adjustment assembly 22. Compared with the first adjustment assembly 21, the second adjustment assembly 22 only differs in the rotatable angle of the carrier seat 1. The first adjustment assembly 21 can control the carrier seat 1 to generate a rotatable angle of 0° to 90°, while the second adjustment assembly 22 can only control the carrier seat 1 to generate a rotatable angle of 0° to 45°. And the rotatable angle of the carrier seat 1 is controlled by the cylinder stroke. Therefore, the stroke of the second adjustment cylinder 221 included in the second adjustment assembly 22 is smaller than the stroke of the first adjustment cylinder 211. The structures and connection relationships of the carrier seat fixing member 212 and the rotation conversion assembly 213 used to convert the linear motion of the second adjustment cylinder 221 into rotational motion are the same as those in the first adjustment assembly 21, so they will not be described in detail here.

[0056] In addition, in order to further fix the lens barrel 3 in the position to be assembled to prevent the lens barrel 3 from having a position offset during the dispensing and lens assembly processes, a clamping mechanism 4 needs to be provided to further fix the position of the lens barrel 3.

[0057] See Figure 3 and Figure 4, the clamping mechanism 4 includes a clamping cylinder 41 and a clamping plate 42, and the clamping cylinder 41 is connected to the clamping plate 42. An abutting portion 421 adapted to abut against the lens barrel 3 is provided on one side of the clamping plate relative to the lens barrel 3. Therefore, the telescopic movement of the clamping cylinder 41 can adjust the clamping plate 42 to approach or move away from the lens barrel 3. When it is necessary to clamp the lens barrel 3, the clamping cylinder 41 can be retracted so that the clamping plate 42 approaches the lens barrel 3 until the abutting portion 421 of the clamping plate 42 abuts against the lens barrel 3, thus realizing the clamping and fixing of the position of the lens barrel 3. After the lens barrel 3 is clamped and fixed, other functional structural components perform operations such as dispensing and mounting on the lens barrel 3. After the operation is completed, the clamping cylinder 41 extends, and at the same time, the clamping plate 42 is controlled to move away from the lens barrel 3, thereby realizing the loosening of the lens barrel 3, so as to facilitate the lens barrel 3 to flow to the next working station for subsequent operation processes.

[0058] See Figure 5 , the clamping mechanism 4 needs to be structurally adjusted according to different adjustment components. Among them, when the bearing seat 1 can rotate 0 to 90°, at this time, the clamping cylinder 41 is located at the bottom of the bearing seat 1, and the clamping plate 42 is arranged parallel to the bearing seat 1. This setting method enables the clamping cylinder 41 to retract, and no matter what angle the bearing seat 1 rotates to, the clamping plate 42 can abut against the lens barrel 3 and cooperate with the bearing seat 1 to press the lens barrel 3 on the bearing seat 1, ensuring the stable position of the lens barrel 3 on the bearing seat 1. And when the bearing seat 1 rotates to 90°, in order to prevent the lens barrel 3 arranged on the bearing seat 1 from slipping, a limiting member 44 can be provided on the clamping plate 42, and a limiting hole 31 is opened on the lens barrel 3. When the clamping plate 42 presses the lens barrel 3, the limiting member 44 is adapted to be inserted into the limiting hole 31, so as to complete the positioning and fixing of the lens barrel 3 and prevent the lens barrel 3 from slipping off the bearing seat 1 when it is at 90°.

[0059] When the bearing seat 1 can only rotate 0 to 45°, an installation block 43 is further provided at the bottom of the clamping cylinder 41, and the inclination angle of the installation block 43 is 45°. The clamping cylinder 41 is arranged on the inclined surface of the installation block 43. At this time, the clamping cylinder 41 forms an angle of 45° with the horizontal plane in the initial state. After the bearing seat 1 rotates 45°, the clamping plate 42 connected to the clamping cylinder 41 is parallel to the bearing seat 1. At this time, when the clamping cylinder 41 retracts, the clamping plate 42 can move relative to the bearing seat 1 to jointly clamp the lens barrel 3 with the bearing seat 1, ensuring that the lens barrel 3 can be stably fixed on the bearing seat 1.

[0060] See Figure 1 and Figure 2, in addition, after the clamping mechanism 4 completes the clamping operation on the lens barrel 3, a dispensing operation needs to be performed at a set position on the lens barrel 3. After the dispensing is completed, the component is placed on the lens barrel so that the component is completely attached to the lens barrel. Then, the curing mechanism 5 provided on the base 7 cures the glue between the component and the lens barrel. The curing mechanism 6 can perform a rotational movement or a linear movement in the vertical direction during curing to ensure that the glue between the component and the lens barrel can be completely cured.
