Description

Technical Field

[0001] This application relates to the technical field of image acquisition, and particularly to a multi-faceted image acquisition device. Background Art

[0002] In the process of product promotion, sales, and applying for design patents, it is crucial to clearly and standardly display the appearance of the product. This usually requires providing the standard six views of the product (front view, rear view, left view, right view, top view, bottom view) and at least one perspective view. These views not only need to truly reflect the appearance design of the product, but also require strict proportional relationships and dimensional consistency among the views to ensure that the design features are accurately presented and understood. Currently, there are two main methods to obtain the standard views of a product: One is to use an ordinary digital camera or mobile phone to take pictures. This is the most convenient and economical way. However, this method has significant drawbacks: it is difficult to precisely control the size and proportion. Ordinary camera lenses have distortion (such as barrel distortion and pincushion distortion), which is particularly obvious at the wide-angle end or when shooting at close range, resulting in curved lines at the edges of the image and distorted product shapes. More importantly, it is very difficult for the photographer to precisely ensure that the optical axis of the camera lens is absolutely perpendicular to the surface of the product being photographed (for the front view) or maintain precise equal angles (for the perspective view). A slight angle deviation will lead to incorrect projection relationships and disproportionate sizes between the views. For example, the side lengths that should be equal will show visible differences in adjacent views. This makes the photographed views difficult to meet the strict requirements for view standardization and proportional consistency in the review of design patents, and also affects the professionalism of promotional materials. Moreover, manually adjusting the position of the product and the angle of the camera to take six front views and one perspective view makes it very difficult to ensure that the absolute position reference of the product is the same in each view, increasing the difficulty of subsequent alignment and comparison.

[0003] The other is to use professional photography studio equipment or a coordinate measuring machine with a photography system. Professional photography studios usually come with large still-life tables, multi-axis precision-positioning gimbals, professional lighting systems, etc., which can better control the angle and distortion, and equipment such as coordinate measuring machines has higher precision. However, such professional equipment generally has the problems of being bulky, complex in structure, and expensive, and is usually fixedly installed in specific locations (such as photography studios, inspection rooms). They are extremely inconvenient to carry and cannot meet the needs of designers to quickly and flexibly take product pictures in offices, exhibition halls, factory workshops, customer sites, or on business trips. And the installation and debugging of the equipment are often time-consuming and laborious.

[0004] Therefore, in the prior art, on the one hand, convenient shooting means cannot guarantee the dimensional ratio accuracy and angle standardization of views, making it difficult to meet professional requirements; on the other hand, professional equipment that can ensure accuracy is too bulky, expensive and lacks portability, and cannot adapt to flexible and fast on-site shooting scenarios. This situation severely restricts the ability of designers, marketers and intellectual property workers to efficiently and accurately obtain product standard views that meet requirements, especially in scenarios that require quick response or mobile office. The market urgently needs a solution that can effectively solve the problems of proportional distortion and angle deviation caused by ordinary camera shooting, and also has good portability, simple operation and controllable cost, so as to improve the efficiency and quality of product view shooting and meet diversified professional needs such as publicity, sales and patent application. Summary of the Invention

[0005] In order to overcome the problems existing in the prior art, the present application provides a multi-faceted image acquisition device.

[0006] The multi-faceted image acquisition device provided by the present application adopts the following technical solutions: A multi-faceted image acquisition device includes a carrying mechanism, which includes a base and a loading platform that is liftably installed on the base. The loading platform includes a frame and a rotating platform that is rotatably installed within the frame. The rotating platform is used to place the product, and a spirit level is embedded at the center of the top surface of the rotating platform. An axis calibration mechanism for calibrating the position of the product is liftably installed within the frame; a shooting mechanism for shooting the product placed on the carrying mechanism, which includes a bracket and a camera that is slidably installed on the bracket. The bottom of the bracket is slidably installed on the base through a seat body. The bracket is a split semi-circular structure and includes several groups of arc-shaped frames. Adjacent frames are connected by a linking mechanism. A positioning groove for fixing the frame is provided on the seat body; a background cloth mechanism for serving as the background of the product placed on the carrying mechanism, which includes a folding board and a bottom lining board and a top lining board connected to the inner side of the folding board. The folding board is fixedly installed on the side of the carrying mechanism away from the shooting mechanism. The bottom lining board is rotatably installed at the center of the inner side of the folding board, and the top lining board is located at the top of the folding board.

[0007] By adopting the above technical solution, first, the lifting platform is adjusted to the corresponding height according to the size of the product, so that the top of the product is located below the top of the bracket. The spirit level embedded in the center of the top surface of the rotating table is used to ensure that the rotating table is in a horizontal state. The product is placed on the top surface of the rotating table. At the same time, the lifting cylinder in the frame drives the axis calibration mechanism to rise above the frame to calibrate the position of the product to ensure that the axis of the product is consistent with the axis of the rotating table. Then, the position of the seat body is adjusted through the sliding structure on the base. The sliding mechanism is driven by a motor to cooperate with the screw sleeve at the bottom of the seat body for transmission, and the seat body is controlled to move on the slide rail on the base, so that when the camera is located at the top and bottom of the bracket, the optical axis of the camera lens is perpendicular to the surface of the rotating table and the optical axis of the lens is on the same straight line as the axis of the rotating table, and the camera on the bracket is moved to a suitable shooting position. The bracket is a split semi-circular structure, which is composed of several groups of arc-shaped frames connected by a linking mechanism. The frames are assembled into a semi-circular structure through the linking mechanism during use to realize the sliding adjustment of the camera on the bracket. When storing, the bracket is disassembled into several frames and fixed to the positioning grooves on the seat body to reduce the overall space occupied by the bracket and facilitate storage. Then, the background cloth mechanism is unfolded. The folding board is fixedly installed on one side of the bearing mechanism away from the shooting mechanism. The bottom lining board is rotatably installed at the center of the inner side of the folding board, and the top lining board is located at the top of the folding board to form the background for product shooting. Among them, the appropriate background color is selected according to the color of the product to be photographed in the background cloth mechanism. After that, the height of the product is adjusted by the lifting platform installed on the base, and the horizontal position of the camera on the bracket is adjusted to make the optical axis of the camera lens perpendicular to the front of the product, so that the camera is adjusted to a suitable position in front of the product. The rotating table is rotated to make different faces of the product face the camera in turn, and the front view, rear view, left view, and right view are respectively photographed. Then, the camera is moved to the top and bottom of the bracket to photograph the top view and bottom view respectively. When photographing the top view, the bottom lining board is used as the background. When photographing the bottom view, the upper half of the bracket is disassembled and the top lining board is used as the background. Then, the position of the camera on the bracket is adjusted and the rotating table is rotated to obtain different angles of the product to photograph the three-dimensional view. During the photographing process, the precise structure control of the bearing mechanism and the shooting mechanism is used to ensure the proportional relationship and dimensional consistency between the views, solve the distortion and angle deviation problems of ordinary camera shooting, and at the same time, the portable structure of the device meets the on-site rapid shooting requirements.

[0008] Preferably, the rotating table includes a supporting part at the top and a transmission part at the bottom. The diameter of the supporting part is smaller than that of the transmission part and the two are integrally formed. An annular protrusion adapted to the annular limiting groove inside the frame is provided around the supporting part. The transmission part is circumferentially arrayed with teeth around, and the teeth on the transmission part are meshed and transmitted with the driving gear at the edge of the frame. The driving gear is driven by a servo motor.

[0009] Preferably, a strip-shaped perforation penetrating through the photographing mechanism to the background part mechanism is horizontally provided on the frame. The rotating table is made of a transparent plate body. The width of the strip-shaped perforation is greater than that of the rotating table and is located at the bottom of the rotating table, and the strip-shaped perforation is used for installing a bottom lining plate.

[0010] By adopting the above technical solution, first place the product on the supporting part of the rotating table. The annular protrusions around the supporting part are adapted to the annular limiting grooves on the inner side of the frame to ensure the stable rotation of the rotating table within the frame. When it is necessary to rotate and adjust the rotating table, start the servo motor. The driving gear at the output end thereof meshes with the circumferentially arranged teeth around the transmission part to drive the rotating table to rotate smoothly, so as to sequentially rotate different faces of the product to appropriate photographing angles. The strip-shaped perforation horizontally provided on the frame penetrates through the photographing mechanism to the background cloth mechanism. Below the transparent rotating plate, the strip-shaped perforation with a width greater than that of the rotating plate is used for installing a bottom lining plate. When taking a top view, the bottom lining plate can be used as the background. When taking a bottom view, the bottom lining plate can be pulled out from the strip-shaped perforation, and a top lining plate is used as the background for product photographing. When the camera takes left view, right view, front view and rear view from the front and the camera slides on the bracket to adjust the position to take a three-dimensional view, the main board and the sub-board are used as the background. The photographing mechanism takes multi-angle photographs of the product on the rotating table to obtain standard six views and a three-dimensional view.

[0011] Preferably, the axis calibration mechanism includes calibration blocks annularly distributed around the rotating table and a driving mechanism for driving the calibration blocks to synchronously move along the center of the rotating table. The driving mechanism includes an annular frame body. The opening of the annular frame body faces inward. A number of groups of power mechanisms are arrayed in the annular frame body. The power mechanism includes symmetrically distributed sliders and driving cylinders for driving the sliders to move. The sliders move along the chutes distributed in the length direction of the annular frame body. A driving rod is rotatably installed on the sliders. The free ends of the symmetrically distributed driving rods are rotatably connected to the back of the calibration blocks and move along the diameter direction of the rotating table under the action of the movement of the sliders. Two sets of through holes distributed vertically are opened on one side of the sliders away from the opening of the annular frame body. Driving belts penetrate through both sets of through holes, and the driving belts are distributed along the annular frame body. Guide rollers for guiding the driving belts are provided between adjacent power mechanisms on the inner side of the annular frame body. The two sliders in a single set of power mechanisms are respectively fixed to a single driving belt.

[0012] By adopting the above technical solution, after placing the product on the turntable, start the axis calibration mechanism, the driving cylinder starts to work, and pushes the slider to move along the chute in the length direction of the annular frame. Since the driving rod rotatably installed on the slider is rotatably connected to the back surface of the calibration block, under the action of the movement of the slider, the driving rod drives the calibration block to move along the diameter direction of the turntable. The two sliders in the same set of power mechanisms are respectively fixed to a single driving belt, and the driving belts passing through the two through holes are distributed along the annular frame. Under the guiding action of the guiding rollers, when the slider of one set of power mechanisms moves, it drives the sliders of other power mechanisms to move synchronously through the driving belt, so that the calibration blocks annularly distributed around the turntable synchronously move towards the center of the turntable, pushing the product to the center position of the turntable, realizing the calibration of the product position, ensuring that the axis of the product is consistent with the axis of the turntable, so that the subsequent photographing mechanism can accurately photograph each view of the product that meets the proportion and specifications. When calibrating the axis of an irregular product, the axis calibration of the product can be carried out in cooperation with the turntable driving the product to rotate.

[0013] Preferably, the linking mechanism includes a length-adjustable link rod between two adjacent frames. The two ends of the link rod are rotatably connected to the mounting rods of the frames, and the mounting rods slide along the sliding grooves in the frames. The link rod includes two sliding rods and a sleeve rod that slide relative to each other. Clips are provided on both side surfaces of the end of the sliding rod, and clamping grooves adapted to the clips are provided on the inner side wall of the sleeve rod, which are respectively used for connection in the two states of disassembled storage and assembly of the split bracket.

[0014] Preferably, the clip on the sliding rod is rotatably installed in the groove on the side surface of the sliding rod, and a spring for driving the clip to rotate out is also installed in the groove. The clamping grooves on both sides in the sleeve rod penetrate through the sleeve rod, and an unlocking rod for ejecting the clip out of the groove is provided in the clamping groove. The unlocking rod penetrates through the sliding sleeve, and a handle is provided at one end of the unlocking rod, and a limiting block is provided at the other end.

[0015] Preferably, a limiting groove is opened along the length direction on the inner side of the frame. The camera is slidably installed in the limiting groove through a base, and a locking bolt for locking the camera in the limiting groove is installed on the base. An angle scale is correspondingly arranged on one side of the frame close to the limiting groove, and an arrow pointing to the angle scale value is opened at the center of the side surface of the base.

[0016] Preferably, extension sections are provided at both the top and bottom of the bracket. The extension section at the top includes a head detachably connected to the frame, and the extension end at the bottom is located on the top surface of the seat body. The limiting grooves on the bracket extend to the heads and the seat body at both ends, and the optical axis of the camera lens is perpendicular to the loading platform when the camera is located at the top and bottom of the bracket.

[0017] By adopting the above technical solution, first assemble the bracket. Pull the handle of the unlocking rod to move the unlocking rod in the card slot. An inclined surface is provided inside the unlocking rod, which can gradually squeeze the clip on the sliding rod back into the slot body. Then, when the outer diameter of the unlocking rod is the same as the outer diameter of the through hole on the sleeve rod, the sliding rod can be separated from the sleeve rod, and the limiting block at the other end of the unlocking rod can prevent the unlocking rod from falling off the sleeve rod. Thus, the clip is pushed back into the slot body by the unlocking rod, and the sliding rod can be pulled out or further inserted into the sleeve rod to adjust the length of the link rod. When adjusted to the appropriate length, the spring drives the clip to rotate out and engage with the card slot of the sleeve rod, realizing the adjustment of the link rod length and meeting the stable connection of adjacent frames during use or storage. Slide the camera through the base and install it in the limiting slot of the frame. According to the shooting requirements, slide the base to the appropriate position and lock the camera in the limiting slot through the locking bolt. The arrow on the side of the base points to the corresponding scale on the angle scale, and the shooting angle of the camera can be accurately adjusted. Extension sections are provided at both the top and bottom of the bracket. The end of the top extension section is detachably connected to the frame, and the bottom extension end is located on the top surface of the seat body. The limiting slot extends to the ends of both ends and the seat body. When the camera is located at the top or bottom of the bracket, the optical axis of the camera lens is perpendicular to the loading platform, and the top view or bottom view of the product can be photographed. During the shooting process, the rotating table drives the product to rotate, and the camera slides on the bracket and adjusts the angle to realize the shooting of the front view, rear view, left view, right view, top view, bottom view, and three-dimensional view of the product, ensuring the proportional relationship and dimensional consistency between the views. After the shooting is completed, pull the unlocking rod to disengage the clip from the card slot, shorten the length of the link rod, disassemble and store the bracket, which is convenient for carrying and storage.

[0018] Preferably, the folding plate includes a main board and auxiliary boards on both sides. A fixing plate is installed at the center of the main board. The inner side of the fixing plate is rotatably connected to a bottom lining board and is connected to the side of the frame body through a fixing bolt. A handle is provided outside the fixing plate. Folding struts are rotatably installed on the fixing plate around the handle. Receiving buckles corresponding to the folding struts are provided on the main board on both sides of the fixing plate. A supporting buckle is installed at the vertex of the auxiliary board far from the main board, and a card slot for engaging with the receiving buckle and the supporting buckle is provided at the free end of the folding strut.

[0019] Preferably, a locking mechanism for fixing the top lining board is rotatably installed on the outer side of the main board above the fixing plate, including a placement groove and a positioning plate rotatably installed in the placement groove. The positioning plate is rotatably connected to the top of the placement groove, and a plane for limiting the rotation angle of the positioning plate is provided at the top of the placement groove. A locking groove corresponding to the positioning plate is also provided on the top lining board, and the positioning plate, the placement groove, and the locking groove are all engaged and connected.

[0020] By adopting the above technical solution, when using the background cloth mechanism, first unfold the folding plate, hold the handle on the outside of the fixed plate, install the fixed plate on the side of the frame away from the bracket through the fixing bolts, rotate the auxiliary plates on both sides of the main plate to unfold them on the same plane as the main plate, and rotate and unfold the folding strut from the fixed plate. When the folding plate is fully unfolded, snap the free end card slot of the folding strut with the support buckle at the top corner of the auxiliary plate to stably support the auxiliary plates on both sides of the main plate. When the bottom lining plate needs to be used, insert the bottom lining plate inside the main plate into the strip-shaped perforations of the frame. When the top lining plate needs to be used, rotate the top lining plate from the back of the main plate to the horizontal position, and snap the positioning plate in the placement groove on the outside of the main plate into the locking groove of the top lining plate. At the same time, use the plane at the top of the placement groove to limit the rotation angle of the positioning plate to complete the fixation of the top lining plate. When the bottom lining plate and the top lining plate are not needed, rotate them downward to fit against the inside of the main plate, thereby forming a complete background according to the shooting requirements and providing a standard background for shooting products on the loading mechanism. After use, loosen the fixing bolts, rotate the top lining plate, the bottom lining plate, and the auxiliary plates respectively to fit against the inside of the main plate, and then fold the main plates on both sides of the fixed plate in half to achieve the storage of the background cloth mechanism, which is convenient for carrying and storing.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the spirit level and the axis calibration mechanism in the loading mechanism, the present application ensures that the horizontal state of the product during placement is consistent with the central reference, solving the problem of inconsistent position references in ordinary shooting. 2. The split semi-circular bracket of the shooting mechanism in the present application can be quickly assembled and stored through the linking mechanism. With the design of the angle scale, the limit slot, and the extension section on the bracket, it realizes the precise vertical positioning and angle adjustment of the camera optical axis and the loading platform. Combined with the rotation of the turntable driven by the servo motor, it effectively eliminates lens distortion and angle deviation, ensuring the proportional relationship and dimensional consistency between views. 3.

Detailed implementation manners

[0024] The following further elaborates on this application Figures 1-9 with reference to the attached

[0025] This application embodiment discloses a multi-faceted image acquisition device.

[0026] Refer to Figures 1-9, A multi-faceted image acquisition device, comprising a carrying mechanism 1, including a base 2 and a stage 3 that is liftably mounted on the base 2. The stage 3 includes a frame 31 and a rotating table 32 that is rotatably mounted within the frame 31. Among them, the rotating table 32 is used to place the product, and a spirit level 321 is embedded in the center of the top surface of the rotating table 32. An axis calibration mechanism 4 for calibrating the position of the product is liftably mounted within the frame 31; a photographing mechanism 5, which is used to photograph the product placed on the carrying mechanism 1, including a bracket 6 and a camera 7 that is slidably mounted on the bracket 6. The bottom of the bracket 6 is slidably mounted on the base 2 through a seat body 62. The bracket 6 is a split semi-circular structure, including four groups of arc-shaped frames 61. Adjacent two frames 61 are connected by a linking mechanism 8. Among them, a positioning groove 621 for fixing the frame 61 is provided on the seat body 62; a background cloth mechanism 9, which is used as the background for the product placed on the carrying mechanism 1, including a folding board 91 and a bottom lining board 92 and a top lining board 93 that are connected to the inner side of the folding board 91. The folding board 91 is fixedly mounted on the side of the carrying mechanism 1 away from the photographing mechanism 5. The bottom lining board 92 is rotatably mounted at the center of the inner side of the folding board 91, and the top lining board 93 is located at the top of the folding board 91. First, the stage 3 is liftably adjusted to the corresponding height according to the size of the product, so that the top of the product is located below the top of the bracket 6. The spirit level 321 embedded in the center of the top surface of the rotating table 32 is used to ensure that the rotating table 32 is in a horizontal state. The product is placed on the top surface of the rotating table 32. At the same time, the axis calibration mechanism 4 is driven by a lifting cylinder within the frame to rise above the frame to calibrate the position of the product, so as to ensure that the axis of the product is consistent with the axis of the rotating table 32. Then, the position of the seat body 62 is adjusted through the sliding structure on the base 2. The sliding mechanism is driven by a motor to cooperate with the lead screw and the lead screw sleeve at the bottom of the seat body 62 for transmission, controlling the movement of the seat body 62 on the slide rail of the base 2, so that when the camera 7 is located at the top and bottom of the bracket 6, the optical axis of the camera 7 lens is perpendicular to the surface of the rotating table 32 and the optical axis of the lens is on the same straight line as the axis of the rotating table 32, moving the camera 7 on the bracket 6 to a suitable photographing position. Among them, the bracket 6 is a split semi-circular structure, and the four groups of arc-shaped frames 61 are connected by a linking mechanism 8. The frames 61 are assembled into a semi-circular structure through the linking mechanism 8 during use to realize the sliding adjustment of the camera 7 on the bracket 6. When storing, the bracket 6 is disassembled into four frames 61 and fixed to the frame 61 by the positioning groove 621 on the seat body 62, reducing the overall space occupied by the bracket 6 and facilitating storage. Then, the background cloth mechanism 9 is unfolded. The folding board 91 is fixedly mounted on the side of the carrying mechanism 1 away from the photographing mechanism 5. The bottom lining board 92 is rotatably mounted at the center of the inner side of the folding board 91, and the top lining board 93 is located at the top of the folding board 91, forming the background for product photographing. Among them, the appropriate background color is selected according to the color of the photographed product in the background cloth mechanism 9.Afterwards, adjust the height of the product by raising and lowering the stage 3 mounted on the base 2, and adjust the horizontal position of the camera 7 on the bracket 6 so that the optical axis of the camera 7 lens is perpendicular to the front of the product, making the camera 7 adjusted to a suitable position in front of the product. Rotate the turntable 32 to make different faces of the product face the camera 7 in turn, and respectively take the front view, rear view, left view, and right view. Then move the camera 7 on the bracket 6 to the top and bottom to take the top view and bottom view respectively. When taking the top view, use the bottom lining plate 92 as the background, and when taking the bottom view, disassemble the upper part of the bracket 61 and use the top lining plate 93 as the background. Then adjust the position of the camera 7 on the bracket 6 and rotate to obtain different angles of the product to take the three-dimensional view. During the shooting process, utilize the precise structure control of the loading mechanism 1 and the shooting mechanism 5 to ensure the proportional relationship and dimensional consistency between the views, solve the distortion and angle deviation problems of the ordinary camera 7 during shooting, and at the same time, the portable structure of the device meets the on-site rapid shooting requirements.

[0027] Refer to Figures 1-9, the rotating table 32 includes a support portion 322 at the top and a transmission portion 323 at the bottom. The diameter of the support portion 322 is smaller than that of the transmission portion 323, and the two are integrally formed. An annular protrusion 3221 adapted to the inner annular limiting groove 613 of the frame 31 is provided around the support portion 322. A plurality of teeth 3231 are circumferentially arranged around the transmission portion 323, and the teeth 3231 on the transmission portion 323 are meshed with the driving gear 311 at the edge of the frame 31 for transmission, wherein the driving gear 311 is driven by a servo motor 312. A strip-shaped through hole 313 penetrating the photographing mechanism 5 to the background portion mechanism is horizontally formed on the frame 31. The rotating table 32 is made of a transparent plate body. The width of the strip-shaped through hole 313 is larger than that of the rotating table 32 and is located at the bottom of the rotating table 32, and the strip-shaped through hole 313 is used to install the bottom lining plate 92. First, place the product on the support portion 322 of the rotating table 32. The annular protrusion 3221 around the support portion 322 is adapted to the inner annular limiting groove 613 of the frame 31 to ensure stable rotation of the rotating table 32 within the frame 31. When it is necessary to rotate and adjust the rotating table 32, start the servo motor 312. The driving gear 311 at its output end is meshed with the teeth 3231 circumferentially arranged around the transmission portion 323 to make the rotating table 32 rotate smoothly, so as to sequentially rotate different surfaces of the product to appropriate photographing angles. The strip-shaped through hole 313 horizontally formed on the frame 31 penetrates the photographing mechanism 5 to the background cloth mechanism 9. Below the transparent rotating plate, the strip-shaped through hole 313 with a width larger than that of the rotating plate is used to install the bottom lining plate 92. When taking a top view, the bottom lining plate 92 can be used as the background. When taking a bottom view, the bottom lining plate 92 can be pulled out from the strip-shaped through hole 313, and the top lining plate 93 is used as the background for product photographing. When the camera 7 takes left, right, front, and rear views from the front and slides on the bracket 6 to adjust the position to take a three-dimensional view, the main board 911 and the sub-board 912 are used as the background, and the product on the rotating table 32 is photographed from multiple angles through the photographing mechanism 5 to obtain standard six views and a three-dimensional view.

[0028] Refer to Figures 1-9, the axis calibration mechanism 4 includes calibration blocks 41 annularly distributed around the turntable 32 and a driving mechanism 42 for driving the calibration blocks 41 to synchronously move along the center of the turntable 32. The driving mechanism 42 includes an annular frame 421, where the opening of the annular frame 421 faces inward. Four groups of power mechanisms 43 are arrayed inside the annular frame 421. The power mechanism 43 includes symmetrically distributed sliders 431 and driving cylinders 432 for driving the sliders 431 to move. The sliders 431 move along the sliding grooves 422 distributed in the length direction of the annular frame 421, and a driving rod 433 is rotatably installed on the sliders 431. The free ends of the symmetrically distributed driving rods 433 are rotatably connected to the back of the calibration blocks 41 and move along the diameter direction of the turntable 32 under the action of the movement of the sliders 431. Two sets of through holes 4311 distributed vertically are formed on one side of the sliders 431 away from the opening of the annular frame 421. Two driving belts 44 penetrate through the two sets of through holes 4311, and the driving belts 44 are distributed along the annular frame 421. Guide rollers 45 for guiding the driving belts 44 are arranged between adjacent power mechanisms 43 on the inner side of the annular frame 421. The two sliders 431 in a single group of power mechanisms 43 are respectively fixed to a single driving belt 44. After placing the product on the turntable 32, start the axis calibration mechanism 4, and the driving cylinders 432 start to work, pushing the sliders 431 to move along the sliding grooves 422 distributed in the length direction of the annular frame 421. Since the driving rods 433 rotatably installed on the sliders 431 are rotatably connected to the back of the calibration blocks 41, under the action of the movement of the sliders 431, the driving rods 433 drive the calibration blocks 41 to move along the diameter direction of the turntable 32. The two sliders 431 in the same group of power mechanisms 43 are respectively fixed to a single driving belt 44, and the driving belts 44 penetrating through the two sets of through holes 4311 are distributed along the annular frame 421. Under the guiding action of the guide rollers 45, when the sliders 431 of a group of power mechanisms 43 move, the sliders 431 of other power mechanisms 43 are driven to move synchronously through the driving belts 44, so that the calibration blocks 41 annularly distributed around the turntable 32 synchronously move along the center of the turntable 32, pushing the product to the center position of the turntable 32, realizing the calibration of the product position, ensuring that the axis of the product is consistent with the axis of the turntable 32, so that the subsequent photographing mechanism 5 can accurately photograph each view of the product that meets the proportion and specifications. When calibrating the axis of an irregular product, the rotation of the turntable 32 can be coordinated to drive the product to rotate for axis calibration of the product.

[0029] Refer to Figures 1-9, the linkage mechanism 8 includes a link rod 81 with adjustable length between two adjacent frames 61.

The inclined surface provided in the unlocking rod 83 can gradually squeeze the clip 8111 on the sliding rod 811 back into the groove body. Then, when the outer diameter of the unlocking rod 83 is the same as the outer diameter of the through hole 4311 on the sleeve rod 812, the sliding rod 811 can be separated from the sleeve rod 812, and the limiting block 832 at the other end of the unlocking rod 83 can prevent the unlocking rod 83 from falling out of the sleeve rod 812. Thus, the clip 8111 can be pushed back into the groove body by the unlocking rod 83, and the sliding rod 811 can be pulled out of or further inserted into the sleeve rod 812 to adjust the length of the link rod 81. When adjusted to the appropriate length, the spring drives the clip 8111 to rotate out and snap into the card slot 8121 of the sleeve rod 812, realizing the adjustment of the length of the link rod 81 to meet the stable connection of adjacent frames 61 during use or storage. Slide the camera 7 through the base 71 into the limiting groove 613 of the frame 61. According to the shooting requirements, slide the base 71 to the appropriate position, and lock the camera 7 in the limiting groove 613 through the locking bolt 72.
