A precise and stable assembly process is crucial for ensuring the optical performance, image quality, and overall stability of the lens. A good auxiliary support can help operators perform lens assembly operations more conveniently and accurately, reducing human error and improving product quality.

[0003] The existing support frame mainly consists of a horizontal flat support platform. The frame is placed on the platform and held in position by friction. To secure the frame, simple clamps may be used, which are then tightened with screws to hold the frame edges in place.

[0004] However, this method relies solely on friction and simple clamps for fixation, making it impossible to accurately position frames of different sizes. During assembly, the frames are prone to shifting due to uneven force. Furthermore, this type of bracket has extremely poor adaptability to different frame sizes. Utility Model Content

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 5 As shown, an auxiliary support for lens assembly includes a base 1, a lifting mechanism, and a support assembly. The lifting mechanism is fixedly mounted on the base 1, and the support assembly is mounted on the lifting mechanism. The support assembly includes a support platform 2 and a clamping plate 3. The support platform 2 has a mounting groove 21 for placing a lens frame 7. The clamping plate 3 is provided on both sides of the inner wall of the mounting groove 21, and the clamping plate 3 is telescopically disposed inside the support platform 2.

[0026] The inner wall of the support platform 2 is provided with telescopic grooves 22 on both sides, and the bottom of the telescopic grooves 22 is provided with guide grooves 23. The clamping plate 3 is telescopically disposed in the telescopic grooves 22, and the bottom of the clamping plate 3 is provided with guide blocks 31. The guide blocks 31 are slidably engaged with the guide grooves 23. The bottom of the support platform 2 is provided with mounting plates 4 on both sides, and a first lead screw 42 is rotatably disposed between the mounting plates 4. The center of the first lead screw 42 is provided with a blocking ring 43, and the threads on both sides of the blocking ring 43 are in opposite directions. The guide blocks 31 pass through the guide grooves 23 and are disposed on the first lead screw 42. The side wall of the mounting plate 4 is provided with a first motor 41, and the output end of the first motor 41 is connected to the first lead screw 42.

[0027] After the first motor 41 starts, its output drives the first lead screw 42 to rotate. Since the threads on both sides of the blocking ring 43 are in opposite directions, the guide block 31 connected to the first lead screw 42 will move in opposite directions along the guide groove 23 as the lead screw rotates, thereby driving the clamping plate 3 to extend and retract within the telescopic groove 22, thus clamping or releasing the frame 7. It can precisely control the movement of the clamping plate 3, achieve stable clamping of frames 7 of different sizes, improve the versatility and practicality of the bracket, and the driving method is simple, reliable, and easy to maintain.

[0028] The lifting mechanism includes a lifting seat 5, a second motor 53, and a second lead screw 52. The bottom of the lifting seat 5 is fixedly mounted on the base 1. A lifting groove 51 is provided on the lifting seat 5. The second lead screw 52 is rotatably mounted in the lifting groove 51. The second motor 53 is mounted on the top of the lifting seat 5, and its output end is connected to the second lead screw 52. A slider 24 is provided on the side wall of the support platform 2. The slider 24 is mounted on the second lead screw 52.

[0029] The second motor 53 starts, driving the second lead screw 52 to rotate within the lifting groove 51. The slider 24 on the side wall of the support platform 2 cooperates with the second lead screw 52. As the lead screw rotates, the slider 24 drives the support platform 2 to move vertically within the lifting groove 51, thereby realizing the lifting and lowering of the bracket assembly. It provides a convenient height adjustment function, allowing operators to quickly adjust the height of the bracket according to actual assembly needs, improving work efficiency. Moreover, the lifting and lowering process is smooth, ensuring the stability of the frame 7 during the lifting and lowering process.

[0030] The bottom dimensions of the frame 7 are adapted to the mounting groove 21, allowing the frame 7 to be placed tightly within the mounting groove 21. The mounting groove 21 provides initial positioning for the frame 7, limiting its horizontal displacement. This ensures the frame 7 is accurately positioned, providing a good foundation for the subsequent clamping of the clamping plate 3, improving the accuracy and stability of the assembly, and reducing assembly errors caused by improper placement of the frame 7.

[0031] The inner arc of the clamping plate 3 is adapted to the inner ring of the mounting groove 21. When the clamping plate 3 clamps the frame 7, the inner ring of the clamping plate 3 can better fit the surface of the frame 7, so that the clamping force is evenly distributed on the frame 7; this enhances the clamping effect of the clamping plate 3 on the frame 7, avoids deformation or displacement of the frame 7 due to uneven clamping force, and further improves the stability of the frame 7 during the assembly process.

[0032] A guide rod 25 is provided within the guide groove 23, and the guide block 31 slides in engagement with the guide rod 25. The guide rod 25 within the groove provides guidance for the movement of the guide block 31. As the guide block 31 moves along the guide groove 23, its sliding engagement with the guide rod 25 restricts its direction of movement, ensuring it can only move along the direction of the guide rod 25. This guarantees the smoothness and accuracy of the guide block 31's movement, thereby ensuring the stability of the clamping plate 3's movement, preventing the clamping plate 3 from shifting during movement, and improving clamping accuracy.

[0033] An elastic layer 6 is provided on the inner ring of the clamping plate 3. This layer can undergo elastic deformation, filling the tiny gap between the clamping plate 3 and the frame 7, and buffering the clamping force of the clamping plate 3 on the frame 7; effectively protecting the surface of the frame 7 from scratches or damage by the clamping plate 3.

[0034] The guide block 31 is adapted to the size of the guide groove 23. The guide block 31 can slide smoothly in the guide groove 23, while the guide groove 23 constrains the guide block 31 to prevent it from shaking or falling out of the guide groove 23 during movement.

[0035] An anti-slip layer 61 is provided on the elastic layer 6. This increases the friction between the clamping plate 3 and the frame 7. When the frame 7 is placed between the clamping plates 3, the anti-slip particles embed into the tiny bumps and recesses on the surface of the frame 7, preventing the frame 7 from sliding. The lifting seat 5 is fixedly connected to the base 1 with screws.

[0036] The entire lens assembly auxiliary bracket uses base 1 as the basic support component, with the lifting mechanism fixed on base 1 and the bracket assembly mounted on the lifting mechanism. The support platform 2 in the bracket assembly has telescopic grooves 22 on both sides inside, and guide grooves 23 at the bottom of the telescopic grooves 22. The clamping plate 3 can extend and retract within the telescopic grooves 22, and the guide block 31 at the bottom of the clamping plate 3 slides in engagement with the guide groove 23. A first lead screw 42 is rotatably mounted between the mounting plates 4 on both sides of the bottom of the support platform 2. The first lead screw 42 has a blocking ring 43 at its center, with the threads on both sides of the blocking ring 43 facing opposite directions. The guide block 31 extends out of the guide groove 23 and is mounted on the first lead screw 42. The output end of the first motor 41 on the side wall of the mounting plate 4 is connected to the first lead screw 42. The lifting mechanism includes a lifting seat 5, a second motor 53, and a second lead screw 52. The bottom of the lifting seat 5 is fixed to the base 1. A lifting groove 51 is opened on the lifting seat 5. The second lead screw 52 is rotatably disposed in the lifting groove 51. The second motor 53 is installed on the top of the lifting seat 5, and its output end is connected to the second lead screw 52. The slider 24 on the side wall of the support platform 2 is disposed on the second lead screw 52. In addition, the inner ring of the clamping plate 3 is provided with an elastic layer 6, and the elastic layer 6 has an anti-slip layer 61. A guide rod 25 is slidably engaged with the guide block 31 in the guide groove 23. The bottom size of the frame 7 is adapted to the mounting groove 21. The curvature of the inner ring of the clamping plate 3 is adapted to the inner ring of the mounting groove 21. The size of the guide block 31 is adapted to the guide groove 23. The lifting seat 5 and the base 1 are fixedly connected by screws.

[0037] The working principle of this utility model is as follows: During lens assembly, the lens frame 7 is first placed in the mounting groove 21 of the support platform 2. The first motor 41 is started, driving the first lead screw 42 to rotate. Because the threads on both sides of the blocking ring 43 are in opposite directions, the two guide blocks 31 connected to the first lead screw 42 cause the clamping plates 3 to move in opposite directions, thereby stably clamping the lens frame 7 in the mounting groove 21. The elastic layer 6 and the anti-slip layer 61 increase the friction between the clamping plates 3 and the lens frame 7, preventing the lens frame 7 from sliding. Simultaneously, the elastic layer 6 prevents the clamping plates 3 from damaging the lens frame 7. If the height of the support assembly needs to be adjusted, the second motor 53 is started, driving the second lead screw 52 to rotate. The slider 24 connected to the second lead screw 52 causes the support platform 2 and the lens frame 7 to rise or fall within the lifting groove 51 to reach the required height position, thus meeting different lens assembly operation requirements.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
