[0030] An embodiment of the present application provides a visual inspection device for jewelry craftsmanship, comprising:

[0031] A support platform, wherein a clamp is rotatably connected to the support platform, the clamp rotates around a first rotation axis, and the jewelry is fixed on the clamp;

[0032] a first camera mechanism, slidably connected to the support platform, and configured to capture the jewelry along a first direction parallel to the length of the first rotation axis;

[0033] A second camera mechanism is slidably connected to the support platform, and the second camera mechanism photographs the jewelry along a second direction perpendicular to the first direction. The visual inspection device for jewelry craftsmanship provided above drives the jewelry to rotate through the clamp, and uses the first camera mechanism and the second camera mechanism to photograph the rotating jewelry from two mutually perpendicular directions to obtain photos of the jewelry at different positions. The jewelry is visually inspected by analyzing the structure of the jewelry in the photos.

[0034] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0035] See also Figure 1-Figure 5 An embodiment of the present application provides a visual inspection device 100 for jewelry craftsmanship, including a support platform 1, a first camera mechanism 2, and a second camera mechanism 3. A clamp 11 is rotatably connected to the support platform 1, and the clamp 11 rotates around a first rotation axis a. The jewelry is fixed on the clamp 11. The first camera mechanism 2 is slidably connected to the support platform 1, and the first camera mechanism 2 shoots the jewelry along a first direction b parallel to the length direction of the first rotation axis a. The second camera mechanism 3 is slidably connected to the support platform 1, and the second camera mechanism 3 shoots the jewelry along a second direction perpendicular to the first direction b.

[0036] Specifically, the support table 1 provides a stable platform for placing and fixing the fixture 11 and the jewelry to be inspected. The fixture 11 rotates around the first rotation axis a, allowing the jewelry to rotate 360 ​​degrees, so that the camera can observe the jewelry in all directions. This design ensures the stability and consistency of the jewelry during the inspection process, thereby making the visual inspection more accurate and reliable. The rotation of the fixture 11 is usually achieved by an electric drive device. This drive device can be various types of motors, such as a stepper motor, a DC motor, or an AC motor. The first camera mechanism 2 shoots the jewelry along a first direction b parallel to the length direction of the first rotation axis a, while the second camera mechanism 3 shoots the jewelry along a second direction perpendicular to the first direction b. This setting ensures that the jewelry can be fully observed at different angles and directions. The combination of the first camera mechanism 2 and the second camera mechanism 3 makes it possible to obtain all-round images of the jewelry, which helps to detect and analyze surface defects, size, shape and other features of the jewelry.

[0037] Furthermore, in actual operation, the jewelry is first fixed to the clamp 11, and then the clamp 11 rotates relative to the support 1, thereby driving the jewelry to rotate 360 ​​degrees. At this time, the first camera 2 and the second camera 3 are fixed to the support frame to capture the jewelry, thereby obtaining photos of the jewelry from various angles.

[0038] In a specific example, the fixture 11 includes a rotating platform 111 and a plurality of fixed blocks 112 . The rotating platform 111 is rotatably connected to the support platform 1 . The plurality of fixed blocks 112 are fixedly connected to the rotating platform 111 around the first rotation axis a.

[0039] Specifically, the rotating table 111 is the main component of the fixture 11. It is a platform or disc-shaped component used to support jewelry. A plurality of fixing blocks 112 are accessories to the fixture 11. These fixing blocks 112 are arranged along a circular trajectory and are primarily used to secure jewelry to the fixing blocks 112 by abutting against the inner wall of the ring-shaped jewelry. These fixing blocks 112 are small blocks fixed to the rotating table 111 to prevent the jewelry from moving during rotation.

[0040] In a specific example, the fixture 11 further includes a fixing member 113 , which passes through the fixing block 112 and is detachably connected to the rotating platform 111 .

[0041] Specifically, the fixing part 113 is an important component of the clamp 11, and its main function is to connect the fixed block 112 and the rotating table 111 and ensure a firm connection between them. It plays the role of fixing and supporting the fixed block 112 in the clamp 11 to ensure the overall stability and reliability of the clamp 11. This part describes the connection method between the fixing part 113 and the fixed block 112 and the rotating table 111. The fixing part 113 passes through the fixed block 112 and is connected to the rotating table 111, and this connection is detachable, which means that the components of the clamp 11 can be easily replaced or adjusted by disassembling the fixing part 113. Generally, a thread is designed on the fixing part 113, and a threaded connection is used to connect the fixing part 113 to the support table 1. This detachable connection design makes the assembly and maintenance of the clamp 11 more convenient. When the clamp 11 needs to be replaced or repaired, the fixing part 113 can be simply disassembled without the need for large-scale disassembly of the entire clamp 11, thereby saving time and labor costs. In addition, the detachable connection also makes the components of the clamp 11 easier to clean and maintain, helping to maintain the cleanliness and stability of the clamp 11.

[0042] In a specific example, a sliding groove 1121 is formed on the fixing block 112 , and the fixing member 113 passes through the fixing block 112 through the sliding groove 1121 . The fixing member 113 is slidably connected to the sliding groove 1121 .

[0043] Specifically, the sliding groove 1121 is a groove or groove structure on the fixed block 112. In this design, the fixed groove extends through the fixture 11, typically located on the surface or edge of the fixed block 112. These sliding grooves 1121 may be provided along a straight line along the fixed block 112, or they may be designed as a curve. The specific shape and size depend on the design requirements of the fixture 11. The fixed member 113 is the component that connects the fixed block 112 and the rotating table 111. It is designed to pass through the sliding groove 1121 on the fixed block 112. This means that the shape and size of the fixed member 113 must match the sliding groove 1121 to ensure that the fixed member 113 can pass through the sliding groove 1121 smoothly. Once the fixed member 113 passes through the sliding groove 1121 on the fixed block 112, it forms a sliding connection with the sliding groove 1121. This connection allows the fixed member 113 to slide freely within the sliding groove 1121, thereby achieving relative movement between the components of the fixture 11. Such a design can make the assembly and adjustment of the clamp 11 more flexible while maintaining a stable connection between the fixing member 113 and the fixing block 112 .

[0044] In a specific example, the support platform 1 includes a base 12 and a sliding platform 13 slidably connected to the base 12, and the first camera mechanism 2 and the second camera mechanism 3 are both slidably connected to the sliding platform 13. The support platform 1 includes a base 12 and a sliding platform 13 slidably connected to the base 12, and the first camera mechanism 2 and the second camera mechanism 3 are both slidably connected to the sliding platform 13.

[0045] Specifically, the base 12 is the main component of the support platform 1. It is a stable platform or base that supports the weight of the entire detection device and provides stability. The sliding platform 13 is a movable component on the base 12 that can slide along the base 12 in a specific direction. The sliding platform 13 is connected to the base 12 by a sliding connection, which allows the sliding platform 13 to slide along the base 12 in a specific direction. This design makes the entire support platform 1 adjustable to accommodate jewelry of different sizes or shapes. The first camera mechanism 2 and the second camera mechanism 3 are two camera systems used to capture images of jewelry. They are respectively connected to the sliding platform 13 and fixed to the sliding platform 13 by a sliding connection. This design allows the camera to adjust its position as the sliding platform 13 moves to meet the needs of shooting at different angles and positions.

[0046] In a specific example, a slide rail 121 is provided on the base 12, and the sliding platform 13 is slidingly connected to the slide rail 121. A first electric roller 122 is provided on the base 12, and the first electric roller 122 is transmission-connected to the sliding platform 13. The first electric roller 122 pushes the sliding platform 13 to move along the slide rail 121.

[0047] Specifically, the slide rail 121 is a linear guide structure, usually located on the surface of the base 12. The function of the slide rail 121 is to provide guidance and support for the movement of the sliding table 13, so that the sliding table 13 can slide smoothly along a specific direction. The sliding table 13 is slidably connected through the slide rail 121, which means that a corresponding slide groove is installed on the sliding table 13, and the slide groove is tightly matched with the slide rail 121, so that the sliding table 13 can slide smoothly along the slide rail 121. The first electric roller 122 is an electric transmission device, which is installed on the base 12. It is usually connected to the pulley or gear on the sliding table 13 to achieve the movement of the sliding table 13. This electric roller is usually driven by a motor and can provide sufficient power to push the sliding table 13 to move along the slide rail 121. Through the rotation of the electric roller, its transmission device will transmit power to the pulley or gear on the sliding table 13, thereby pushing the sliding table 13 to move along the slide rail 121. Such a design makes the movement of the sliding platform 13 more stable and controllable, and can ensure that the camera maintains a stable movement state during the shooting process.

[0048] In a specific example, the sliding platform 13 has a transmission part 131 , and the transmission part 131 is in transmission connection with the first motorized roller 122 .

[0049] Specifically, the transmission unit 131 and the first motorized roller 122 are connected via a transmission mechanism to achieve power transmission. This transmission mechanism can be a gear drive, belt drive, chain drive, or other transmission device. Through this transmission connection, the power generated by the first motorized roller 122 can be effectively transmitted to the transmission unit 131.

[0050] In a specific example, two second motorized rollers 132 are provided on the sliding platform 13 , and the two second motorized rollers 132 respectively drive the first camera mechanism 2 and the second camera mechanism 3 to move along the first direction b.

[0051] Specifically, the second motorized roller 132 is a roller assembly mounted on the sliding platform 13, typically supported by bearings and freely rotatable. These motorized rollers provide power for the first and second camera mechanisms 2 and 3 to slide along the first direction b. The second motorized roller 132 is connected to the first and second camera mechanisms 2 and 3 via some type of transmission structure. This transmission structure can be a pulley, chain, belt, or the like, which converts the motion of the motorized roller into motion of the first and second camera mechanisms 2 and 3. Thus, when the sliding platform 13 moves, the first and second camera mechanisms 2 and 3 will correspondingly move along the first direction b.

[0052] In a specific example, the support platform 1 has a rotation driving device 4, and the rotation driving device 4 drives the clamp 11 to rotate around the first rotation axis a.

[0053] Specifically, the rotation drive 4 is a mechanical device mounted on the support 1. Its function is to provide power and mechanical rotation mechanism to drive the clamp 11 to rotate about a specified axis. This rotation axis is usually perpendicular to the base of the clamp 11 or the axis of the support 1, and is used to control the horizontal rotation of the clamp 11 and the jewelry therein.

[0054] Furthermore, the rotation drive device 4 has many different types and designs, and its selection depends on the specific application needs, budget and technical requirements. Among them, electric devices, pneumatic devices and manual devices are more common. The electric drive device is powered by an electric motor and can achieve efficient and precise rotation control. The electric drive device usually includes a motor, a reducer, a drive shaft and a control system. By controlling the speed and direction of the motor, the rotation speed and direction of the clamp 11 can be accurately controlled. The pneumatic drive device is powered by compressed air and is usually used in applications that require a higher speed and a larger torque. The advantages of the pneumatic drive device are adjustable speed and fast response, which are suitable for some occasions that require fast operation. The manual drive device usually adopts a manual operating device such as a handle, a crank or a handwheel to achieve rotation through manual operation. Although the speed and accuracy may not be as good as the electric or pneumatic drive device, the manual drive device is usually less expensive and suitable for some simple operations or low-frequency use.

[0055] In a specific example, the first imaging mechanism 2 includes a first camera 21 and a plurality of first light sources 22 , and the second imaging mechanism 3 includes a plurality of second light sources 32 and a second camera 31 ;

[0056] A plurality of first light sources 22 are disposed around the first camera 21 , and a plurality of second light sources 32 are disposed around the second camera 31 .

[0057] Specifically, the first imaging mechanism 2 consists of a first camera 21 and a plurality of first light sources 22. The first camera 21 is a camera device used to capture images of jewelry, responsible for capturing the appearance features and details of the jewelry. The plurality of first light sources 22 are used to provide lighting to ensure that the camera can capture clear images under appropriate lighting. Similarly, the second imaging mechanism 3 consists of a second camera 31 and a plurality of second light sources 32. The second camera 31 is also a camera device used to capture images of jewelry, and its functions are similar to those of the first camera 21. The plurality of second light sources 32 provide appropriate lighting conditions to ensure that the second camera 31 can capture clear images. The first light source 22 and the second light source 32 are arranged to surround their respective cameras. This arrangement is intended to provide uniform and sufficient lighting to ensure that the camera can capture the true appearance and details of the jewelry during the shooting process. The surround setting of the light source can reduce the appearance of shadows and light spots, thereby improving the quality and clarity of the captured images.

[0058] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
