Description

Technical Field

[0001] This invention relates to the field of photographic equipment technology, specifically to a multifunctional photographic device and its usage method. Background Technology

[0002] Jewelry is usually made of high-value materials such as precious metals, gemstones, and jade. With its unique texture, exquisite cutting techniques and rich design, it has extremely high ornamental and collectible value.

[0003] In order to showcase jewelry on e-commerce platforms, promote it in catalogs, and create digital archives, high-definition image capture is required. Due to the small size and complex surface structure of jewelry, its internal clarity, cut details, and refracted light at different angles all need to be accurately reproduced through precise multi-angle macro photography. High-quality objective image capture is not only the core of facilitating online transactions, but also an important basis for subsequent product appraisal and evaluation.

[0004] Current jewelry photography often involves manually setting up a tripod and using a softbox for manual focusing. This method is inefficient and makes it difficult to ensure that the shooting angle and lighting are consistent for each shot. To address this shortcoming, automatic shooting devices with rotating trays are now commonly used to work with cameras for continuous automatic shooting. However, existing automatic shooting devices usually fix the camera at a certain height or only support single vertical sliding. When dealing with complex jewelry, the camera cannot flexibly change its spatial pitch shooting position. Even if some devices can change the camera's spatial coordinates by swinging the tripod, the camera lens will tilt with the swing of the tripod, failing to automatically compensate and always keep it vertically aligned with the jewelry below. This results in partial defocusing or perspective deviation in the captured image, making it difficult to meet the requirements for automated image acquisition of jewelry from multiple positions, without blind spots, and always maintaining a vertical perspective. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multifunctional photography device and its usage method, which solves the problem that existing camera lenses tilt as the bracket swings, cannot automatically compensate and always remain vertically aligned with the jewelry below, resulting in partial defocusing or perspective deviation in the captured image.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional photographing device, comprising a housing, a bracket fixedly connected to the inner center of the housing, a movable frame provided on the inner rear side of the bracket, a sliding seat provided on the inner side of the movable frame, a support rod rotatably connected to the inner side of the sliding seat, a camera fixedly connected to the front end of the support rod, a control mechanism provided on the outer side of the movable frame, and a rotating mechanism provided at the bottom of the bracket.

[0007] Preferably, the control mechanism includes a fixed frame and a synchronous belt. The fixed frame is fixedly connected to the top rear side of the support. A servo motor is fixedly connected to the rear side of the fixed frame. The output end of the servo motor passes through the rear side of the fixed frame and the movable frame in sequence and is fixedly connected to a connecting block. The outer side of the connecting block is fixedly connected to the interior of the movable frame. Pulleys are rotatably connected to the upper and lower sides of the interior of the movable frame. The two pulleys are connected by the synchronous belt. The outer side of the synchronous belt is fixedly connected to a sliding seat. A second servo motor is fixedly connected to the lower rear wall of the movable frame. The output end of the second servo motor passes through the rear side of the movable frame and is fixedly connected to the lower pulley.

[0008] Preferably, the rotating mechanism includes a servo motor four, which is fixedly connected to the bottom left side of the bracket. The output end of the servo motor four is fixedly connected to a gear one through the bottom of the bracket. A transmission shaft is rotatably connected to the bottom left side of the bracket. A gear two is fixedly connected to the outside of the transmission shaft. The gear two meshes with the gear one. A tray is fixedly connected to the top of the transmission shaft.

[0009] Preferably, the control mechanism further includes a proximity switch, which is fixedly connected to the top of the mounting bracket.

[0010] Preferably, the control mechanism further includes two guide rails, which are fixedly connected to the left and right rear ends of the movable frame, respectively, and the rear ends of the guide rails are slidably connected to the sliding seat.

[0011] Preferably, the rotating mechanism further includes an angle sensor, which is fixedly connected to the bottom of the bracket, and the bottom end of the drive shaft passes through the bracket.

[0012] Preferably, the control mechanism further includes a servo motor three, which is fixedly connected to the rear side of the sliding seat, and the output end of the servo motor three is fixedly connected to the support rod.

[0013] Preferably, an upper light box is fixedly connected to the top of the outer casing, and an auxiliary fill light box is fixedly connected to the right side of the outer casing.

[0014] Preferably, a controller is fixedly connected to the upper right side of the front wall of the housing, and the controller is electrically connected to servo motor one, servo motor two, servo motor three and servo motor four respectively.

[0015] A method for using a multi-functional photography device includes the following steps:

[0016] S1: Place the jewelry to be photographed on the tray at the bottom of the bracket, and turn on the upper light box on the top of the casing and the auxiliary fill light box on the right to illuminate the jewelry on the tray.

[0017] S2: The controller starts servo motor two, which drives the pulley on the lower side to rotate. The sliding seat moves up and down along the guide rail via the synchronous belt, thereby adjusting the shooting height of the camera. When the sliding seat moves to the proximity switch sensing area at the top of the fixed frame, the proximity switch sends a signal and the controller cuts off the power of servo motor two to prevent excessive movement and collision.

[0018] S3: The controller starts the servo motor to drive the connecting block to rotate, which causes the movable frame to swing to change the spatial shooting position of the camera. When the movable frame swings, the controller simultaneously starts the servo motor to drive the support rod to rotate. The support rod drives the camera to perform a compensating rotation of the same angle, so that the camera remains vertically downward and aimed at the jewelry on the tray after it is offset by the swing of the movable frame.

[0019] S4: The camera captures images of the jewelry. After a single capture is completed, the controller starts the servo motor four to drive gear one to rotate. Gear one will then drive gear two to rotate. Gear two will drive the transmission shaft to rotate, causing the tray to move in a circle, thereby changing the position of the jewelry. When the transmission shaft rotates, the angle sensor monitors the rotation angle in real time and feeds it back to the controller. Based on this, the controller controls the servo motor four to stop at the next shooting position, repeating the camera capture action until multi-position image capture is completed.

[0020] This invention provides a multifunctional photographic device and its usage method. It has the following beneficial effects:

[0021] 1. This invention uses a second servo motor to drive the lower pulley to rotate. The pulley pulls the sliding seat up and down along the guide rail via a synchronous belt, thereby moving the camera to adjust its height. A first servo motor drives the connecting block to rotate, causing the entire movable frame to swing to change the camera's spatial shooting position. When the movable frame swings, a third servo motor is activated to synchronously drive the support rod to rotate, causing the camera to perform a corresponding compensating rotation. This ensures that the camera can be vertically aligned with the jewelry below after swinging with the movable frame, avoiding local defocusing and viewing angle deviation caused by the camera lens tilting due to the change in spatial shooting position.

[0022] 2. This invention starts a servo motor to drive gear one to rotate. Gear one then drives gear two, which meshes with it, to rotate. When gear two rotates, it drives the tray to rotate through the transmission shaft, changing the orientation of the jewelry placed on the tray. During the rotation of the transmission shaft, an angle sensor penetrating the bottom of the bracket monitors and provides data feedback on the rotation angle of the transmission shaft in real time. This allows the controller to precisely control the operation and start / stop of servo motor four, ensuring that the tray stays at the preset shooting position after each rotation. No manual intervention is required to rotate the jewelry, thus improving the accuracy and continuity of the automated shooting process. Attached Figure Description

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Reference Figure 6 , Figure 7 and Figure 8This invention provides a multifunctional photographing device, including a housing 1. A bracket 4 is fixedly connected to the middle of the inner side of the housing 1. A movable frame 5 is provided on the rear side of the inner side of the bracket 4. A sliding seat 6 is provided on the inner side of the movable frame 5. A support rod 7 is rotatably connected to the inner side of the sliding seat 6. A camera 8 is fixedly connected to the front end of the support rod 7. A control mechanism 2 is provided on the outer side of the movable frame 5. A rotating mechanism 3 is provided at the bottom of the bracket 4. The control mechanism 2 includes a fixed frame 21 and a synchronous belt 25. The fixed frame 21 is fixedly connected to the rear top of the bracket 4. A servo motor 22 is fixedly connected to the rear side of the fixed frame 21. The output end of the servo motor 22 passes through the rear side of the fixed frame 21 and the movable frame 5 and is fixedly connected to a connecting block 23. The outer side of the connecting block 23 is fixedly connected to the interior of the movable frame 5. When the servo motor 22 is started, it can drive the movable frame 5 to rotate through the connecting block 23. The upper and lower sides of the interior of the movable frame 5 rotate. The movable frame 5 is connected by a pulley 24, which is connected by a synchronous belt 25. The outer side of the synchronous belt 25 is fixedly connected to the sliding seat 6. A servo motor 26 is fixedly connected to the lower side of the rear wall of the movable frame 5. The output end of the servo motor 26 passes through the rear side of the movable frame 5 and is fixedly connected to the lower pulley 24. The servo motor 26 drives the lower pulley 24 to rotate, which in turn drives the synchronous belt 25 to rotate and drives the sliding seat 6 to move. The control mechanism 2 also includes two guide rails 28, which are fixedly connected to the left and right ends of the rear side of the movable frame 5 respectively. The rear side of the guide rails 28 is slidably connected to the sliding seat 6. The guide rails 28 are used to guide the movement of the sliding seat 6. The control mechanism 2 also includes a servo motor 27, which is fixedly connected to the rear side of the sliding seat 6. The output end of the servo motor 27 is fixedly connected to the support rod 7. The servo motor 27 drives the camera 8 to rotate through the support rod 7.

[0035] Specifically, servo motor 26 is started to drive the lower pulley 24 to rotate. The lower pulley 24 drives the upper pulley 24 to rotate via synchronous belt 25. When synchronous belt 25 rotates, it pulls the sliding seat 6 to move up and down along guide rail 28, thereby adjusting the shooting height of camera 8. Servo motor 22 drives connecting block 23 to rotate. Connecting block 23 drives movable frame 5 to swing, thereby changing the position of camera 8. When movable frame 5 swings, servo motor 27 is started simultaneously to drive support rod 7 to rotate. Support rod 7 drives camera 8 to perform a compensating rotation of the same angle, so that camera 8 can always remain vertically facing downward and aligned with tray 36 after it swings and shifts with movable frame 5.

[0036] Reference Figure 2 , Figure 4 and Figure 5The rotating mechanism 3 includes a servo motor 31, which is fixedly connected to the bottom left side of the bracket 4. The output end of the servo motor 31 passes through the bottom of the bracket 4 and is fixedly connected to a gear 32. The servo motor 31 can drive the gear 32 to rotate. The bottom left side of the bracket 4 is rotatably connected to a transmission shaft 33. The outside of the transmission shaft 33 is fixedly connected to a gear 35, which meshes with the gear 32. The top of the transmission shaft 33 is fixedly connected to a tray 36. When the gear 32 rotates, it can drive the gear 35 to rotate through the meshing of the gear 35. The rotating mechanism 3 also includes an angle sensor 34, which is fixedly connected to the bottom of the bracket 4. The bottom end of the transmission shaft 33 passes through the bracket 4. The angle sensor 34 can monitor the rotation of the transmission shaft 33.

[0037] Specifically, servo motor 4 31 is started to drive gear 1 32 to rotate. The rotation of gear 1 32 will drive the meshing gear 2 35 to rotate. Gear 2 35 drives the transmission shaft 33 to rotate. When the transmission shaft 33 rotates, it drives the tray 36 at the top to rotate, thereby changing the position of the jewelry placed on the tray 36. During the rotation of the transmission shaft 33, the angle sensor 34 at the bottom collects and provides feedback on the rotation angle data of the transmission shaft 33 in real time. With the start and stop of servo motor 4 31, the tray 36 is accurately stopped at the preset shooting position after each rotation.

[0038] Reference Figure 3 and Figure 6 The control mechanism 2 also includes a proximity switch 29, which is fixedly connected to the top of the mounting bracket 21;

[0039] Specifically, during the process of adjusting the height of the sliding seat 6 by pulling it along the guide rail 28 using the synchronous belt 25, the proximity switch 29 on the top of the fixed frame 21 senses the extreme position of the sliding seat 6 moving upward. When the sliding seat 6 moves to the sensing area of ​​the proximity switch 29, the proximity switch 29 sends an arrival feedback signal and cuts off the operating power of the servo motor 26 to prevent the sliding seat 6 from moving too downward, causing collision and hardware damage.

[0040] Reference Figure 1 and Figure 2 The top of the outer shell 1 is fixedly connected to the upper light box 10, and the right side of the outer shell 1 is fixedly connected to the auxiliary light box 9.

[0041] Specifically, when the camera 8 is capturing images, the main lighting source is provided by the downward light from the upper light box 10, and the auxiliary fill light box 9 on the right side of the housing 1 provides side lighting for the jewelry on the tray 36. This compensates for the blind spots in side lighting caused by a single light source, eliminates the shadows cast by the concave and convex surfaces and sides of the jewelry, and ensures the brightness and detail clarity of each surface of the jewelry when shooting from multiple angles.

[0042] Reference Figure 1 and Figure 2 A controller 11 is fixedly connected to the upper right side of the front wall of the outer casing 1. The controller 11 is electrically connected to servo motor 1 22, servo motor 26, servo motor 3 27 and servo motor 4 31 respectively.

[0043] Specifically, the controller 11 sends signal commands down through the circuit to coordinate the swing arm angle of servo motor 1 22, the lifting stroke of servo motor 26, the compensation rotation angle of servo motor 3 27, and the station flow sequence of servo motor 4 31, so that the operation of each motor forms an automatic linkage shooting operation process, avoiding manual adjustment of each axis one by one.

[0044] Example 2:

[0045] A method for using a multi-functional photography device includes the following steps:

[0046] S1: Place the jewelry to be photographed on the tray 36 at the bottom of the bracket 4, and turn on the upper light box 10 on the top of the outer casing 1 and the auxiliary fill light box 9 on the right to illuminate the jewelry on the tray 36.

[0047] S2: Controller 11 starts servo motor 26, which drives the pulley 24 on the lower side to rotate. Through the synchronous belt 25, the sliding seat 6 moves up and down along the guide rail 28, thereby adjusting the shooting height of the camera 8. When the sliding seat 6 moves to the sensing area of ​​the proximity switch 29 at the top of the fixed frame 21, the proximity switch 29 sends a signal and the controller 11 cuts off the power of servo motor 26 to prevent excessive movement and collision.

[0048] S3: Controller 11 starts servo motor 22 to drive connecting block 23 to rotate, causing movable frame 5 to swing to change the spatial shooting position of camera 8. When movable frame 5 swings, controller 11 simultaneously starts servo motor 27 to drive support rod 7 to rotate. Support rod 7 drives camera 8 to perform the same angle of compensation rotation, so that camera 8 remains vertically facing down and aligned with the jewelry on tray 36 after it swings and shifts with movable frame 5.

[0049] S4: Camera 8 acquires images of the jewelry. After a single acquisition is completed, controller 11 starts servo motor 4 31 to drive gear 1 32 to rotate. Gear 1 32 will then drive gear 2 35 to rotate. Gear 2 35 drives transmission shaft 33 to rotate, causing tray 36 to move in a circle, thereby changing the position of the jewelry. When transmission shaft 33 rotates, angle sensor 34 monitors the rotation angle in real time and feeds it back to controller 11. Controller 11 then controls servo motor 4 31 to stop at the next shooting position and repeats the acquisition action of camera 8 until multi-position image acquisition is completed.

[0050] Working principle:

[0051] When taking multi-position, multi-angle photographs of the jewelry, servo motor 26 is activated. Activation of servo motor 26 drives the lower pulley 24 to rotate. The rotation of the lower pulley 24 drives the upper pulley 24 to rotate via synchronous belt 25. Since the outer side of synchronous belt 25 is fixedly connected to the sliding seat 6, the rotation of synchronous belt 25 pulls the sliding seat 6 up and down along the guide rail 28. The movement of the sliding seat 6, in turn, drives the camera 8 to adjust its height via support rod 7. Furthermore, servo motor 22 drives the connecting block 23 to rotate. Since the outer side of the connecting block 23 is fixed to the inside of the movable frame 5, the rotation of the connecting block 23... When the camera moves, it will cause the movable frame 5 to swing, thereby moving the camera 8 to different shooting positions. At this time, in order to keep the camera 8 vertical, the servo motor 27 is activated. The activation of the servo motor 27 will drive the support rod 7 to rotate. When the support rod 7 rotates, it will cause the camera 8 to rotate to compensate, so that the camera 8 can always remain vertically aligned with the jewelry below after it swings and shifts with the movable frame 5. Through the coordinated operation of the servo motor 26, servo motor 12 and servo motor 27, the spatial shooting position of the camera 8 can be adjusted and kept vertical without disassembly, avoiding the problem of incomplete image acquisition caused by blind spots.

[0052] Furthermore, during panoramic or different workstation capture with camera 8, the servo motor 31 at the bottom of bracket 4 is activated. The servo motor 31 drives gear 32 to rotate. Since gear 2 35 is meshed with gear 32, the rotation of gear 1 32 drives gear 2 35 to rotate. The rotation of gear 2 35 drives the transmission shaft 33 to rotate, which in turn drives the tray 36 to rotate. This causes the jewelry placed on the tray 36 to change its orientation. During the rotation of the transmission shaft 33, the angle sensor 34, which runs through the bottom of bracket 4, can monitor and provide feedback on the rotation angle of the transmission shaft 33 in real time. This allows the controller 11 to control the start and stop of the servo motor 31, ensuring that the tray 36 can accurately stop at the preset shooting position after each rotation. The entire standardized shooting process can be completed automatically with camera 8 without manual intervention to rotate the jewelry, improving the stability of the automated image acquisition process.
