DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0036] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0037] The present application provides a fireworks filling detection device for detecting the military gunpowder filling of combination fireworks during the fireworks production process.

[0038] refer to Figures 1-6 The fireworks loading inspection device includes a frame 10, an inspection platform 20, an image acquisition component 30, an image processing component, a loading mechanism 50, a first pushing mechanism 60, and a second pushing mechanism 70. The image acquisition component 30 is used to capture a single-tube image of the combined fireworks positioned on the inspection platform 20. The image processing component is connected to the image acquisition component 30 via a data transmission line. The image acquisition component 30 may be equipped with one or more image acquisition elements (cameras), each of which captures a single-tube image of the combined fireworks. Multiple image acquisition elements can simultaneously capture multiple single-tube images of the combined fireworks. After capturing a single-tube image, each image acquisition element in the image acquisition component 30 transmits the captured image to the image processing component via the data transmission line. The image processing component processes and identifies the image to determine if the fireworks have been properly loaded. The image processing component is a computer device with image processing capabilities, comprising a memory chip and an image processing chip. Furthermore, the image processing component is a PLC or industrial computer.

[0039] The detection platform 20 is tilted along the first direction; the two sides of the detection platform 20 along the second direction are respectively the first side and the second side; the first direction and the second direction are perpendicular to each other. Figure 2 The first direction x and the second direction y are perpendicular to each other. During testing, the combined fireworks W enter the testing platform 20 from the first side and exit from the second side of the testing platform 20, moving along the second direction y. The testing platform 20 is tilted in the first direction x, which is perpendicular to the direction of entry and exit of the combined fireworks.

[0040] The loading mechanism 50 is used to load fireworks onto the testing platform 20. A loading plate 51 is located at a first side of the testing platform 20. The loading plate 51 transfers fireworks combinations onto the testing platform 20 by switching between a first angular position and a second angular position. Specifically, the loading mechanism 50 includes the loading plate 51 and a first drive source 52. The loading plate 51 is located at a first side of the testing platform 20. The first drive source 52 is capable of driving the loading plate 51 between the first angular position and the second angular position. When the loading plate 51 is in the second angular position, the loading plate 51 aligns with the angular position of the testing platform 20. A first pushing mechanism 60 pushes fireworks combinations onto the loading plate 51 when the loading plate 51 is in the first angular position. A second pushing mechanism 70 pushes fireworks combinations onto the loading plate 51 when the loading plate 51 is in the second angular position.

[0041] In a specific embodiment, the first angular position is a horizontal position. When the first driving source 52 drives the loading plate 51 to rotate to the horizontal position, the first pushing mechanism 60 can push the assembled fireworks on the conveyor line onto the loading plate 51. When the loading plate 51 is at the second angular position, the loading plate 51 and the detection platform 20 are aligned at the same inclination angle. At this time, the second pushing mechanism 70 can push the assembled fireworks on the loading plate 51 onto the detection platform 20. Figure 1 In the structure shown, the loading plate 51 is in the second angular position, and along the first direction, the inclination angle and inclination direction are consistent with the detection platform 20, that is, the angular position of the loading plate 51 and the detection platform 20 are aligned. At this time, the combined fireworks on the loading plate 51 can be smoothly pushed onto the detection platform 20.

[0042] exist Figure 6 In the structure shown, the loading plate 51 is hinged on the frame 10, and the first driving source 52 is a cylinder, which is arranged at the bottom of the loading plate 51. As the first driving source 52 extends and retracts, the loading plate 51 rotates around the hinge axis to a first angle position and a second angle position.

[0043] In one embodiment of the present application, the first drive source 52 can also drive the loading plate 51 to vibrate back and forth. Furthermore, a limiting assembly 53 is provided on the loading plate 51; the limiting assembly 53 includes a fixed member 531, a movable member 532, and a fourth drive source 533. The fourth drive source 533 can drive the movable member 532 to clamp or release the assembled fireworks between the fixed member 531 and the movable member 532.

[0044] Specifically, after the first pushing mechanism 60 pushes the combination firework onto the loading plate 51, the first drive source 52 can drive the loading plate 51 to vibrate back and forth several times to adjust the distribution of the military gunpowder within the firework tube, facilitating subsequent testing. Furthermore, a limiting assembly 53 is provided on the loading plate 51. This limiting assembly 53 is used to limit the position of the combination firework placed on the loading plate 51, preventing the combination firework from changing position or detaching from the loading plate during the shaking process. Specifically, the combination firework is located between the fixed member 531 and the movable member 532. The fourth drive source 533 can drive the movable member 532 to clamp or release the combination firework. When the fourth drive source 533 drives the movable member 532 to clamp the combination firework, the combination firework is confined to the loading plate, allowing the combination firework to vibrate synchronously with the loading plate 51.

[0045] During operation, first, the first driving source 52 drives the loading plate 51 to rotate to the first angular position (horizontal position). At this time, the first pushing mechanism 60 pushes the combined fireworks onto the loading plate 51. After the first pushing mechanism 60 pushes the combined fireworks onto the loading plate 51, the fourth driving source 533 drives the movable member 532 to clamp the combined fireworks. Then, the first driving source 52 drives the loading plate 51 to vibrate back and forth several times. After the vibration is completed, the first driving source 52 drives the loading plate 51 to rotate to the second angular position. Moreover, the fourth driving source 533 drives the movable member 532 to release the combined fireworks. At this time, the second pushing mechanism 70 pushes the combined fireworks on the loading plate 51 onto the detection platform 20, where the combined fireworks are detected in a tilted state.

[0046] In one embodiment of the present application, the fireworks loading and detection device further includes a discharge platform 80; the discharge platform 80 is located on the second side of the detection platform 20, is tilted, and is aligned with the angular position of the detection platform 20, and is capable of receiving the combined fireworks pushed out from the detection platform 20. In this structural setting, the angular position of the discharge platform 80 is aligned with the detection platform 20, so that the combined fireworks on the detection platform 20 can be smoothly pushed onto the discharge platform 80 after completing the detection. In addition, the discharge platform 80 is tilted, and there will be a misalignment with the horizontal plane, with a height difference. When the combined fireworks are pushed out of the discharge platform 80 and re-enter the horizontal plane, there will be a certain amount of shaking, which can adjust the distribution of military gunpowder in the fireworks tube so that it is more evenly distributed in the fireworks tube. In addition, it should be noted that the discharge platform is mounted on the frame and is tilted. During operation, the angle of the discharge platform remains unchanged.

[0047] The fireworks loading and detection device further includes a third pushing mechanism 90 and a material platform 100. The material platform 100 is arranged horizontally and has a height difference with the discharge platform 80. The third pushing mechanism 90 is used to push the assembled fireworks on the discharge platform 80 onto the material platform 100. Here, the discharge platform 80 is arranged at an angle and has a height difference with the material platform 100. When the assembled fireworks are pushed out of the discharge platform 80 and onto the material platform 100, they will vibrate slightly, which can adjust the distribution of the military gunpowder within the fireworks tube, making it more evenly distributed.

[0048] Furthermore, the fireworks loading inspection device also includes a fourth pushing mechanism 110; this mechanism is used to push out combination fireworks identified as qualified by the image processing component from the material platform 100. Here, the fourth pushing mechanism 110 is linked to the image processing component. When the combination fireworks are identified as qualified by the image processing component, the fourth pushing mechanism 110 pushes the combination fireworks out of the material platform 100.

[0049] In one embodiment of the present application, the second pushing mechanism 70 simultaneously pushes the fireworks assembly on the loading plate 51 onto the testing platform 20 and onto the discharge platform 80. Each time a test is performed, the second pushing mechanism 70 pushes the fireworks assembly on the testing platform 20 that has been tested out of the testing platform 20, while simultaneously pushing the fireworks assembly on the loading plate 51 that has not been tested onto the testing platform 20.

[0050] In one embodiment of the present application, the second pushing mechanism 70 includes: a guide rail 71, a sliding seat 72, a pushing member 73, a second driving source 74, and a third driving source 75; the guide rail 71 is arranged on the frame 10; the sliding seat 72 is slidably mounted on the guide rail 71; the second driving source 74 is used to drive the sliding seat 72 to move along the guide rail 71; the third driving source 75 is mounted on the sliding seat 72 and connected to the pushing member 73; the pushing member 73 is provided with a first pushing portion 731 and a second pushing portion 732. When the second driving source 74 drives the sliding seat 72 to move along the guide rail 71, the first pushing portion 731 is used to push the combined fireworks on the loading plate 51 onto the detection platform 20, and the second pushing portion 732 is used to push the combined fireworks on the detection platform 20 onto the discharging platform 80; the third driving source 75 can drive the pushing member 73 to move the first pushing portion 731 and the second pushing portion 732 thereon to extend into or out of the lateral position of the combined fireworks.

[0051] Specifically, the third drive source 75 is mounted on the sliding seat 72 and connected to the push member 73. When the second drive source 74 drives the sliding seat 72 to move along the guide rail 71, the third drive source 75 and the push member 73 move synchronously. Before the push member 73 begins pushing materials, the third drive source 75 drives the push member 73 to move its first push portion 731 and second push portion 732 into position to the side of the combined fireworks. After completing a push and before retracting, the third drive source 75 drives the push member 73 to move its first push portion 731 and second push portion 732 out of position to the side of the combined fireworks to avoid conflict with the combined fireworks. Furthermore, when the push member 73 moves with the sliding seat 72, the first push portion 731 is used to push the combined fireworks on the loading plate 51 onto the inspection platform 20, while the second push portion 732 is used to push the combined fireworks on the inspection platform 20 onto the discharge platform 80.

[0052] In one embodiment of the present application, the detection platform 20 and the image acquisition component 30 are configured to be angle-adjustable and can be adjusted to a horizontal state. In some usage scenarios, the detection platform 20 and the image acquisition component 30 can be adjusted to a horizontal state for use, and the actions of other components can also be adapted accordingly to accommodate the horizontal state of the detection platform 20. In addition, it should be understood that under this setting, the detection platform 20 and the image acquisition component 30 can be adjusted to a horizontal state for use, or to an inclined state for use. The technical features described in the previous section correspond to the case where the detection platform 20 is tilted along the first direction.

[0053] In the embodiment of the present application, each pushing mechanism, including the first pushing mechanism, the second pushing mechanism, the third pushing mechanism, and the fourth pushing mechanism, can use a cylinder as a driving element to push the combined fireworks through the extension and contraction of the cylinder.

[0054] The embodiment of the present application further provides a fireworks production line, comprising the fireworks filling detection device provided in the previous section. The fireworks filling detection device is used to detect the filling status of the combined fireworks after the combined fireworks are filled with military-grade nitrate.

[0055] It should also be noted that the fireworks production line includes equipment for loading gunpowder, paper babas, and effect inner tubes.
