[0024] The carrier component 4 includes a support plate 12, with two positioning grooves 13 on its top. These grooves are located on opposite sides of the support plate 12 and communicate with its lower surface. Clamping wheels 9 are located inside the two positioning grooves 13. A bearing 14 is located at the axis of each clamping wheel 9; the inner ring of the bearing 14 is fixedly connected to the shaft of the clamping wheel 9, and the outer ring is fixedly connected to the inner wall of the positioning groove 13. This design allows the clamping wheels 9 to rotate freely within the positioning grooves 13 while maintaining a stable axial position. The positioning assembly 2 also includes two mounting brackets 15, which are fixedly connected to the bottom of the support plate 12. The clamping wheels 9 are rotatably connected to opposite sides of the two mounting brackets 15. The camera module 5 is bolted between the two mounting brackets 15. A buffer ring 16, made of rubber, is provided on the outer side of the clamping wheels 9 to effectively reduce friction between the clamping wheels 9 and the explosive fragments, ensuring smooth movement of the explosive fragments during transport. The top of the support plate 12 has a through hole 25, which is located between two positioning grooves 13. The diameter of the through hole 25 is larger than the lens diameter of the camera module 5, thereby ensuring that the camera module 5 can capture images of the surface of the explosive fragments without obstruction.

[0025] The visual recognition component 3 includes a camera module 5. Several light source modules 6 are fixedly mounted on the outer side of the camera module 5, and these modules are evenly distributed around it. Each light source module 6 has a light-transmitting sheet 7 on its end face, which optimizes the light propagation path and ensures that the camera module 5 can acquire clear images under different lighting conditions. An image acquisition unit 8 is located at the bottom of the camera module 5. This unit is used to acquire image data of the explosive fragment surface in real time and transmit the acquired images to a processing system for analysis and classification. The camera module 5 is bolted between two mounting brackets 15, positioned between two clamping wheels 9, enabling high-precision image acquisition of the explosive fragment surface.

[0026] The adjusting component 10 includes a guide frame 17, with a groove 18 inside the guide frame 17. The width of the groove 18 matches the thickness of the sliding connector 11. Baffles 19 are provided at both ends of the groove 18, and are fixedly connected to the ends of the guide frame 17 by screws to limit the movement range of the sliding connector 11.

The two ends of the elastic element 24 are fixedly connected to the slider 20 and the inner wall of the guide frame 17, respectively. The elastic element 24 is a compression spring, which provides a buffering effect when the slider 20 moves to avoid damage to the equipment due to mechanical impact.

[0027] In practical use, the explosive fragments are placed between two clamping wheels 9, which move the fragments smoothly by rolling. A buffer ring 16, made of rubber, is located on the outer side of each clamping wheel 9, effectively reducing friction between the clamping wheels 9 and the explosive fragments, ensuring the fragments are not damaged during transport. A camera module 5 is located between the two clamping wheels 9, with an image acquisition unit 8 at its bottom for real-time image data acquisition of the explosive fragment surface. The image acquisition unit 8 transmits the acquired images to a processing system for analysis and classification. Users can quickly determine the presence and type of defects on the explosive fragment surface using the detection results generated by the processing system. The combined use of the light source module 6 and the light-transmitting plate 7 ensures that the camera module 5 can acquire clear images under different lighting conditions, thereby improving detection accuracy.

[0028] When the equipment needs to be adjusted to accommodate explosive fragments of different specifications, adjustments can be made using the adjusting component 10 and the sliding connector 11. The specific operating steps are as follows: First, loosen the locking bolt 23 to allow the slider 20 to slide freely within the groove 18. Then, adjust the position of the slider 20 according to the specifications of the explosive fragments to ensure that the clamping wheel 9 can stably clamp the explosive fragments. After adjustment, tighten the locking bolt 23 to fix the slider 20 in its current position. During the movement of the slider 20, the elastic element 24 provides a buffering effect, preventing equipment damage due to mechanical impact and extending the equipment's service life.

[0029] The support plate 12 has a through hole 25 at its top, located between two positioning slots 13. The diameter of the through hole 25 is larger than the lens diameter of the camera module 5, ensuring that the camera module 5 can capture images of the explosive fragment surface without obstruction. The support plate 12 also has a connecting post 21 at its top, the top of which is fixedly connected to the slider 20, allowing the support plate 12 to adjust its position as the slider 20 moves. The bottom of the support plate 12 is fixedly connected to a mounting bracket 15, which provides stable support for the entire device, ensuring that the device does not shake or shift during operation.

[0030] This invention achieves stable clamping and conveying of explosive fragments during surface defect detection by using a positioning component 2 and a vision recognition component 3. Simultaneously, the vision recognition component 3 performs high-precision image acquisition of the explosive fragment surface. The image acquisition unit 8 transmits the acquired images to a processing system for analysis and classification. Users can quickly determine the presence and type of defects on the explosive fragment surface using the detection results generated by the processing system. The clamping wheel 9 in the positioning component 2 moves the explosive fragment smoothly by rolling, avoiding the complex transmission mechanism design of traditional equipment. Furthermore, the design of the buffer ring 16 reduces the friction between the clamping wheel 9 and the explosive fragment, further improving the stability of the equipment. The light source module 6 and the light-transmitting sheet 7 in the vision recognition component 3 work together to ensure that the camera module 5 can acquire clear images under different lighting conditions, thereby improving the accuracy of the detection. The design of the adjusting component 10 and the sliding connector 11 allows the equipment to adapt to explosive fragments of different specifications, enhancing its versatility. In addition, the elastic element 24 provides a buffering effect during the movement of the slider 20, avoiding equipment damage caused by mechanical impact and extending the service life of the equipment.

[0031] To enable those skilled in the art to better understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.

[0032] Before starting the equipment, the explosive fragments are first placed between the two clamping wheels 9. The clamping wheels 9 contact the explosive fragments via a buffer ring 16 on their outer side. The buffer ring 16 is made of rubber, which effectively reduces the force generated by friction, thus ensuring that the explosive fragments move smoothly during transport. At this time, a bearing 14 is provided at the axis of the clamping wheel 9. The inner ring of the bearing 14 is fixedly connected to the rotating shaft of the clamping wheel 9, and the outer ring is fixedly connected to the inner wall of the positioning groove 13. This design allows the clamping wheel 9 to rotate freely within the positioning groove 13 while maintaining a stable axial position, avoiding detection errors caused by vibration or displacement.

[0033] Once the explosive fragments are stably clamped, the clamping wheels 9 roll along the through-hole 25 of the support plate 12. The camera module 5 is positioned between the two clamping wheels 9, with its lens facing the through-hole 25. Because the diameter of the through-hole 25 is larger than the lens diameter of the camera module 5, the camera module 5 can capture images of the explosive fragment surface without obstruction. An image acquisition unit 8 is located at the bottom of the camera module 5, used to acquire image data of the explosive fragment surface in real time and transmit the acquired images to the processing system for analysis and classification. During this process, the light source module 6 and the light-transmitting sheet 7 work together. The light source module 6 is evenly distributed around the camera module 5, and the light-transmitting sheet 7 optimizes the light propagation path, ensuring that the camera module 5 can acquire clear images under different lighting conditions. This design significantly improves the accuracy and stability of image acquisition.

[0034] When the equipment needs to be adjusted to accommodate explosive fragments of different specifications, the operator can make adjustments using the adjusting component 10 and the sliding connector 11. Specifically, first, loosen the locking bolt 23 to allow the slider 20 to slide freely within the groove 18. The bottom of the slider 20 has a protrusion 22 that embeds into and slides within the groove 18, ensuring the slider 20 remains stable during movement. According to the specifications of the explosive fragments, the operator adjusts the position of the slider 20 until the clamping wheel 9 can stably clamp the explosive fragments. After adjustment, tighten the locking bolt 23 to fix the slider 20 in its current position. During the movement of the slider 20, the elastic element 24 provides a cushioning effect, preventing equipment damage due to mechanical impact and extending the equipment's service life.

[0035] In addition, a connecting column 21 is provided at the top of the support plate 12. The top end of the connecting column 21 is fixedly connected to the slider 20, so that the support plate 12 can adjust its position as the slider 20 moves. The bottom of the support plate 12 is fixedly connected to the mounting bracket 15, which provides stable support for the entire device, ensuring that the device will not shake or shift during operation. This design not only improves the stability of the device but also enhances its versatility, enabling it to adapt to explosive fragments of different specifications.

[0036] In actual operation, after the camera module 5 acquires image data of the explosive fragment surface through the image acquisition unit 8, it transmits the data to the processing system for analysis and classification. The processing system quickly determines whether there are defects on the surface of the explosive fragment and their type by identifying and comparing features in the image. This process achieves high-precision detection of defects on the surface of the explosive fragment, while simplifying the operation process and reducing the manufacturing cost of the equipment.

[0037] In summary, through the above steps and structural design, this utility model achieves efficient detection of surface defects in explosive fragments, solving the problems of complex equipment structure, high manufacturing cost, and cumbersome operation in the prior art.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
