Camera lens alignment training device

Abstract

The application provides a camera lens alignment training device, which comprises a first connecting ring and a second connecting ring for sleeving a camera lens. By arranging an adjusting mechanism, people can control the motor to drive the threaded rod to rotate under the transmission of the first gear and the second gear, and then drive the concave block and the second connecting ring to move, so as to adjust the position of the lens. When the electric push rod is controlled to extend or retract, the arc-shaped frame can move, the threaded rod does not rotate, and then the arc-shaped frame can only drive the second connecting ring to rotate and cannot drive the second connecting ring to move when moving. When the second connecting ring rotates, the second connecting ring can drive the lens to rotate, so as to adjust the focal length. In cooperation with the fixing mechanism, the camera can be damped, and the focal length of the camera and the position of the lens can also be adjusted by the adjusting mode, the distance of the picture can be adjusted, and the definition of the shooting picture can be improved.

Description

Technical Field

[0001] This invention relates to the field of drones, and more specifically, to a camera lens alignment and adjustment device. Background Technology

[0002] For the use of front-facing cameras on high-altitude drones, when installing a C-mount lens, the known distance (flange focal length) from the mounting reference plane to the CCD target surface is 17.5mm. If this distance is not equal to 17.5mm, the lens and camera cannot focus properly, resulting in a blurry image. Therefore, two adjustment methods are used during lens installation. The first method adjusts the tightness of the lens threads to adjust the distance to the CCD target surface, achieving focusing and image clarity. The second method uses a rear image adjustment ring, in which case the CCD target surface moves backward (forward) relative to the mounting reference plane, achieving focusing and image clarity. Furthermore, technical requirements stipulate that the image information acquired by each batch of front-facing cameras must match the target reference object in a fixed position and size, with an error within 5 pixels. This can easily lead to batch-specific image inconsistencies and, under vibration, lens loosening, causing image blurring.

[0003] For example, the Chinese invention patent / utility model patent (application number: CN202211375278.8) discloses "An intelligent photography system and method for reducing drone shaking". The specification states that when a drone shakes during flight, and the shaking amplitude is large, the shock absorption device of the above-mentioned technical solution fails to function, which will cause the camera lens to shake, resulting in blurry and difficult-to-view video. The above patent can corroborate the defects of the prior art.

[0004] Therefore, we made improvements by proposing a camera lens alignment and adjustment device. Summary of the Invention

[0005] The purpose of this invention is to address the current situation where lenses produce inconsistent images due to batch installation, and the resulting image blurring caused by lens loosening under vibration.

[0006] To achieve the above-mentioned objectives, the present invention provides a camera lens alignment and adjustment device to improve the aforementioned problems.

[0007] The application is as follows:

[0008] The system includes a first connecting ring and a second connecting ring for holding the camera lens. Adjustment mechanisms for adjusting the position of the second connecting ring are provided on both sides of the first connecting ring. Each adjustment mechanism includes two arc-shaped frames respectively located on both sides of the first connecting ring. A threaded rod and a concave block are located in the middle of each arc-shaped frame to drive the movement of the second connecting ring. By setting up the adjustment mechanism, a motor can be controlled to rotate the threaded rod under the transmission of a first gear and a second gear, thereby moving the concave block and the second connecting ring to adjust the position of the lens. When the electric push rod is extended or retracted, the arc-shaped frames can move, but the threaded rod does not rotate. Therefore, when the arc-shaped frames move, they can only rotate the second connecting ring, not move it. When the second connecting ring rotates, it can rotate the lens to adjust the focal length. Combined with the fixing mechanism, this can reduce camera vibration. Furthermore, this adjustment method can also adjust the camera's focal length and lens position, adjusting the image distance and improving the clarity of the captured image.

[0009] As a preferred technical solution of this application, the adjustment mechanism further includes a slide groove formed in the middle of the arc frame, one end of the threaded rod is connected to a bracket through a bearing, one end of the bracket is fixedly connected to the circumferential side of the first connecting ring, and the other end of the threaded rod passes through one side of the arc frame.

[0010] As a preferred technical solution of this application, the outside of the threaded rod is threadedly connected to one end of the concave block, and the inside of the concave block is slidably connected to the outside of the second connecting ring.

[0011] As a preferred technical solution of this application, the inner wall of the arc frame and the circumferential side of the second connecting ring are both provided with matching threads. Through the threads on the arc frame and the second connecting ring, the second connecting ring can rotate when the arc frame and the second connecting ring are relatively displaced, thereby driving the lens inside the second connecting ring to rotate and adjust the focal length.

[0012] As a preferred technical solution of this application, one end of the threaded rod is fixedly connected to a second gear, the second gear meshes with a first gear, a plug rod is fixedly connected to the middle of the first gear, and a motor for driving the plug rod to rotate is fixedly installed on one side of the first connecting ring. The end of the plug rod and the output shaft of the motor are both provided with matching teeth.

[0013] As a preferred technical solution of this application, a V-shaped rod is connected to the first gear via a rotating shaft. Both ends of the V-shaped rod are fixedly connected to one end of the arc-shaped frame via connecting shafts. Two electric push rods are fixedly connected to the V-shaped rod. A plurality of circular slots for installing the electric push rods are opened on one side of the first connecting ring. By setting the V-shaped rod and the electric push rods, the V-shaped rod can provide good support for the first gear when the first gear drives the second gear, so that the first gear can rotate stably. When the electric push rod extends, the first gear disengages from the second gear, and the V-shaped rod can drive the arc-shaped frame to move, thereby driving the second connecting ring to rotate, which has strong functionality.

[0014] As a preferred technical solution of this application, the second connecting ring is provided with a limiting mechanism for clamping the lens. The limiting mechanism includes a plurality of electromagnets evenly arranged inside the second connecting ring. A plurality of clamping blocks that cooperate with the electromagnets are evenly arranged on the inner side of the second connecting ring. By setting the limiting mechanism, when the clamping blocks are sucked into the interior of the second connecting ring under the action of the electromagnets, the movement of the second connecting ring can only drive the lens to move and adjust the image size. When the clamping blocks clamp the lens under the action of the spring, the rotation of the second connecting ring can drive the lens to rotate and adjust the focal length.

[0015] As a preferred technical solution of this application, a spring sheet is provided between the clamping block and the electromagnet.

[0016] As a preferred technical solution of this application, the first connecting ring is provided with a fixing mechanism. The fixing mechanism includes two arc-shaped grooves respectively opened at the top and bottom of the first connecting ring. A T-shaped rod is slidably connected inside the arc-shaped groove. Springs located inside the arc-shaped grooves are fixedly connected to the bottom of both sides of the T-shaped rod. By setting the fixing mechanism, the first connecting ring and the second connecting ring can be installed on the drone. When the drone shakes, the shaking amplitude of the cameras in the first connecting ring and the second connecting ring can be reduced, thereby improving the shooting quality. In addition, during the packaging and transportation process, the T-shaped rod can be moved to screw the bolt into the slot, thereby fixing the position of the arc-shaped frame. When the electric push rod is de-energized, the arc-shaped frame and the first connecting ring cannot be relatively displaced, which facilitates transportation and has strong functionality.

[0017] As a preferred technical solution of this application, both ends of the T-shaped rod are connected with bolts, and a slot for bolt insertion is provided at one end of the outer side of the arc-shaped frame. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] As described in the background section, the image is blurred due to batch-specific inconsistencies in lens installation and lens loosening under vibration.

[0032] To address this technical problem, the present invention provides a camera lens alignment and adjustment device, which is used to improve the quality of camera shooting.

[0033] For details, please refer to Figure 1 The camera lens alignment and adjustment device specifically includes:

[0034] The camera lens alignment and adjustment device includes a first connecting ring 1 and a second connecting ring 2 for holding the camera lens. Adjustment mechanisms 3 for adjusting the position of the second connecting ring 2 are provided on both sides of the first connecting ring 1. Each adjustment mechanism 3 includes two arc-shaped frames 312 respectively located on both sides of the first connecting ring 1. A threaded rod 302 and a concave block 303 for driving the movement of the second connecting ring 2 are located in the middle of each arc-shaped frame 312. By setting the adjustment mechanisms 3, a person can control a motor 308, which, under the transmission of a first gear 306 and a second gear 305, drives the threaded rod 302. The rotation causes the concave block 303 and the second connecting ring 2 to move, adjusting the position of the lens. When the electric push rod 311 is extended or retracted, the arc frame 312 can move, while the threaded rod 302 does not rotate. Thus, when the arc frame 312 moves, it can only rotate the second connecting ring 2 but cannot move it. When the second connecting ring 2 rotates, it can rotate the lens to adjust the focal length. In conjunction with the fixing mechanism 4, it can reduce the vibration of the camera. This adjustment method can also adjust the focal length and position of the camera lens, adjust the distance of the image, and improve the clarity of the captured image.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Based on the camera lens alignment adjustment device, the adjustment mechanism 3 also includes a slide groove 301 opened in the middle of the arc frame 312. One end of the threaded rod 302 is connected to the bracket 304 through the bearing. One end of the bracket 304 is fixedly connected to the circumferential side of the first connecting ring 1. The other end of the threaded rod 302 passes through one side of the arc frame 312, ensuring that the threaded rod 302 will not obstruct the arc frame 312 during the movement of the arc frame 312.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the camera lens alignment and adjustment device, the outside of the threaded rod 302 is threadedly connected to one end of the concave block 303, and the inside of the concave block 303 is slidably connected to the outside of the second connecting ring 2. By setting the concave block 303, the concave block 303 can drive the second connecting ring 2 to move smoothly during the movement.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the camera lens alignment and adjustment device, the inner wall of the arc frame 312 and the circumferential side of the second connecting ring 2 are provided with matching threads. Through the threads on the arc frame 312 and the second connecting ring 2, when the arc frame 312 and the second connecting ring 2 are relatively displaced, the second connecting ring 2 can rotate, thereby driving the lens inside the second connecting ring 2 to rotate and adjust the focal length.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the camera lens alignment and adjustment device, a second gear 305 is fixedly connected to one end of the threaded rod 302. The second gear 305 meshes with a first gear 306. A plug rod 307 is fixedly connected to the middle of the first gear 306. A motor 308 for driving the plug rod 307 to rotate is fixedly installed on one side of the first connecting ring 1. The end of the plug rod 307 and the output shaft of the motor 308 are both provided with matching teeth, which ensures that the output shaft of the motor 308 can drive the plug rod 307 to rotate when it rotates, and the plug rod 307 can disengage from the output shaft of the motor 308.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Based on the camera lens alignment and adjustment device, a V-shaped rod 309 is connected to the first gear 306 via a rotating shaft. Both ends of the V-shaped rod 309 are fixedly connected to one end of the arc frame 312 via connecting shafts. Two electric push rods 311 are fixedly connected to the V-shaped rod 309. Multiple circular slots 310 for installing the electric push rods 311 are opened on one side of the first connecting ring 1. By setting the V-shaped rod 309 and the electric push rods 311, the V-shaped rod 309 can provide good support for the first gear 306 when the first gear 306 drives the second gear 305, so that the first gear 306 can rotate stably. When the electric push rod 311 extends, the first gear 306 disengages from the second gear 305, and the V-shaped rod 309 can drive the arc frame 312 to move, thereby driving the second connecting ring 2 to rotate. It has strong functionality.

[0044] Example 2

[0045] The camera lens alignment and adjustment device provided in Example 1 is further optimized, specifically, as follows: Figure 1 and Figure 5 As shown, the second connecting ring 2 is provided with a limiting mechanism 5 for clamping the lens. The limiting mechanism 5 includes multiple electromagnets 501 evenly arranged inside the second connecting ring 2. Multiple clamping blocks 503 that cooperate with the electromagnets 501 are evenly arranged on the inner side of the second connecting ring 2. By setting the limiting mechanism 5, when the clamping blocks 503 are sucked into the interior of the second connecting ring 2 under the action of the electromagnets 501, the movement of the second connecting ring 2 can only drive the lens to move and adjust the image size. When the clamping blocks 503 clamp the lens under the action of the spring piece 502, the rotation of the second connecting ring 2 can drive the lens to rotate and adjust the focal length.

[0046] Furthermore, such as Figure 1 and Figure 5 As shown, a spring piece 502 is provided between the clamping block 503 and the electromagnet 501. By providing the spring piece 502, when the electromagnet 501 is de-energized, the clamping block 503 can move under the action of the spring piece 502, thereby clamping the lens inside the second connecting ring 2.

[0047] Example 3

[0048] The camera lens alignment and adjustment device provided in Embodiment 1 or 2 is further optimized, specifically, as follows: Figure 1 and Figure 6As shown, a fixing mechanism 4 is provided on the first connecting ring 1. The fixing mechanism 4 includes two arc-shaped grooves 401 respectively opened at the top and bottom of the first connecting ring 1. A T-shaped rod 402 is slidably connected inside the arc-shaped grooves 401. Springs 403 located inside the arc-shaped grooves 401 are fixedly connected to the bottom of both sides of the T-shaped rod 402. By setting the fixing mechanism 4, the first connecting ring 1 and the second connecting ring 2 can be installed on the drone. When the drone shakes, the shaking amplitude of the cameras in the first connecting ring 1 and the second connecting ring 2 can be reduced, thereby improving the shooting quality. During the packaging and transportation process, the T-shaped rod 402 can be moved to screw the bolt 404 into the slot 405, thereby fixing the position of the arc frame 312. When the electric push rod 311 is de-energized, the arc frame 312 and the first connecting ring 1 cannot be relatively displaced, which facilitates transportation and has strong functionality.

[0049] Furthermore, bolts 404 are inserted and connected to both ends of the T-shaped rod 402, and a slot 405 for inserting the bolts 404 is provided at one end of the outer side of the arc-shaped frame 312.

[0050] The usage process of the camera lens alignment and adjustment device provided by this invention is as follows:

[0051] The camera lens is placed between the first connecting ring 1 and the second connecting ring 2. The second connecting ring 2 is in contact with one end of the lens. When the position of the lens needs to be adjusted, the control motor 308 is activated. Under the transmission of the first gear 306, the second gear 305, and the threaded rod 302, the concave block 303 moves and drives the second connecting ring 2 to move. The second connecting ring 2 rotates and moves between the two arc-shaped frames 312. Since the clamping block 503 does not contact the lens, the second connecting ring 2 only drives the lens to move. When the focal length of the lens needs to be adjusted, the control electromagnet 501 is de-energized. Under the action of the spring 502, the clamping block 503 contacts the lens, and the control electric push rod 311 extends. The electric push rod 311 drives the V-shaped rod 309 to move. The V-shaped rod 309 drives the arc-shaped frame 312 to move, driving the second connecting ring 2 to rotate. Since the threaded rod 302 does not rotate, the second connecting ring 2 can only rotate and cannot move, thereby driving the lens to rotate and adjust the focal length.
