Detailed implementation mode

[0033] The following are specific embodiments of the present application. In combination with the accompanying drawings, the technical solutions of the present application will be further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help comprehensively understand the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present application. In addition, descriptions of known functions and structures are omitted for clarity and conciseness.

[0034] It should be noted that, without conflict, the implementation modes in the present application and the features in the implementation modes can be combined with each other.

[0035] The present application provides a fireworks detection device for detecting each single tube on a combined fireworks after the loading process. During detection, the moving detection path can be adjusted as needed to adapt to different single tube arrangements. The fireworks detection device provided by the present application can be applied after the loading of gunpowder, the loading of paper baba, and the loading of the effect inner tube to detect the corresponding loaded materials to confirm whether the loading is qualified.

[0036] Reference Figures 1-6 , the fireworks detection device includes a fixed frame 10, a moving detection component 40, a first driving source 50a and a second driving source 50b, and an image processing component 60. Among them, the moving detection component 40 includes a first moving frame 41 and a plurality of image acquisition units 42 arranged on the first moving frame 41; the image acquisition unit 42 is used to acquire the single tube image of the combined fireworks. The first driving source 50a can drive the first moving frame 41 to move along the first direction x; the second driving source 50b can drive the first moving frame 41 to move along the second direction y; the first direction x and the second direction y are perpendicular directions in the horizontal plane; the first driving source 50a is a servo motor or a stepper motor; the second driving source 50b is a servo motor or a stepper motor. The image processing component 60 is connected to the image acquisition unit 42 through a data transmission line.

[0037] The image acquisition unit 42 arranged on the first moving frame 41 is used to acquire the single tube image of the combined fireworks. One or more image acquisition units 42 are arranged on the first moving frame 41. In an implementation mode of the present application, a plurality of image acquisition units 42 are arranged on the first moving frame 41, and the plurality of image acquisition units 42 can simultaneously acquire the single tube images of a plurality of combined fireworks. When a plurality of image acquisition units 42 are arranged on the first moving frame 41, when the first moving frame 41 moves to each acquisition position, the plurality of image acquisition units 42 can simultaneously perform image acquisition and respectively acquire the images of a plurality of different single tubes. Reference Figure 1, in a specific embodiment, three image acquisition units 42 are arranged on the first moving frame 41, and the three image acquisition units 42 can simultaneously acquire images of three different single cylinders. The image acquisition unit 42 is specifically a camera.

[0038] Reference Figure 5 , the image processing component 60 is connected to the image acquisition unit 42 through a data transmission line. After the image acquisition unit 42 acquires the image of the single cylinder, the image is transmitted to the image processing component 60 through the data transmission line. The image processing component processes and identifies the image to determine whether the loading is qualified. The image processing component is a computer device with image processing functions, having a storage chip and an image processing chip. In one embodiment, the image processing component is a PLC or an industrial control computer. In Figure 5 In the shown structure, multiple image acquisition units 42 are connected to the image processing component 60 through data transmission lines. As the first moving frame 41 moves to multiple different acquisition positions, the multiple image acquisition units 42 continuously upload the acquired images to the image processing component for identification until all the single cylinders on the combined fireworks are covered.

[0039] The movement detection component 40 includes a first moving frame 41 and an image acquisition unit 42. Driven by the first driving source 50a, the movement detection component 40 can move in the first direction x. Driven by the second driving source 50b, the movement detection component 40 can move in the second direction y. Reference Figure 6 , in a specific embodiment, the controller controls the first driving source 50a and the second driving source 50b to drive the first moving frame 41. Since the first driving source 50a is a servo motor or a stepper motor and the second driving source 50b is a servo motor or a stepper motor, the controller can control the image acquisition unit 42 to move precisely in the first direction x and the second direction y, so as to acquire images of all the single cylinders on the combined fireworks.

[0040] Specifically, in the first embodiment, both the first driving source 50a and the second driving source 50b are servo motors. In the second embodiment, both the first driving source 50a and the second driving source 50b are stepper motors. In the third embodiment, the first driving source 50a is a servo motor and the second driving source 50b is a stepper motor. In the fourth embodiment, the first driving source 50a is a stepper motor and the second driving source 50b is a servo motor.

[0041] It should be understood that the first direction x and the second direction y are perpendicular to each other in the horizontal plane. The first driving source 50a drives the first moving frame 41 to move along the first direction x, and the second driving source 50b drives the first moving frame 41 to move along the second direction y. Driven by the first driving source 50a and the second driving source 50b, the moving detection component 40 can move along different paths in the horizontal plane, so as to adapt to detecting combined fireworks with different single-tube arrangement modes. In addition, the first driving source 50a can drive the moving detection component to move to three different precise positions in the first direction x for single-tube image acquisition. At the same time, the second driving source 50b can drive the moving detection component to move to three different precise positions in the second direction y for single-tube image acquisition.

[0042] In an embodiment of the present application, the first driving source 50a can drive the first moving frame 41 to move to at least three different detection coordinate positions x in the first direction x i ; at different detection coordinate positions x i , the image acquisition unit 42 is aligned with single tubes in different rows on the combined fireworks. The second driving source 50b can drive the first moving frame 41 to move to at least three different detection coordinate positions y in the second direction y i ; at different detection coordinate positions y i , the image acquisition unit 42 is aligned with single tubes in different columns on the combined fireworks.

[0043] In a schematic working process, the first driving source 50a first drives the first moving frame 41 to the first detection coordinate position x1 in the first direction x. At the first detection coordinate position x1, the image acquisition unit is aligned with three or more single tubes on the combined fireworks along the second direction y. At this time, the second driving source 50b drives the first moving frame 41 to move to three or more detection coordinate positions y i (including detection coordinate position y1,..., detection coordinate position y n , n≥3) for loading detection respectively. Then, the first driving source 50a continues to drive the first moving frame 41 to the second detection coordinate position x2 in the first direction x. At the second detection coordinate position x1, the image acquisition unit is aligned with three or more single tubes on the combined fireworks along the second direction y. At this time, the second driving source 50b drives the first moving frame 41 to move to three or more detection coordinate positions y i (including detection coordinate position y1,..., detection coordinate position y n , n≥3) for loading detection respectively. In this way, the first driving source 50a drives the first moving frame 41 to the i-th detection coordinate position x in the first direction x i , at the i-th detection coordinate position x iAbove, the image acquisition unit aligns with three or more single barrels on the combined fireworks in the second direction y, and the second drive source 50b drives the first moving frame 41 to move to three or more detection coordinate positions y in the second direction y. i Loading detection is performed separately. Through the above moving paths in the first direction x and the second direction y, the image acquisition unit can cover and acquire images of all single barrels on the combined fireworks.

[0044] In an embodiment of the present application, a second moving frame 70 is further provided between the first moving frame 41 and the fixed frame 10. The fixed frame 10 is provided with a first slide rail 11 extending in the first direction x. The second moving frame 70 is slidably mounted on the first slide rail 11 and can be guided by the first slide rail 11 to move in the first direction x. The second moving frame 70 is provided with a second slide rail 71 extending in the second direction y. The first moving frame 41 is slidably mounted on the second slide rail 71 and can be guided by the second slide rail 71 to move in the second direction y.

[0045] Specifically, the first moving frame 41 can slide along the second direction y on the second slide rail 71, enabling the image acquisition unit to move in the second direction y. The second slide rail 71 is arranged on the second moving frame 70. When the second moving frame 70 moves in the first direction x on the first slide rail 11, the first moving frame 41 follows the second moving frame 70 to move in the first direction x, thereby enabling the image acquisition unit to move in the first direction x.

[0046] In an embodiment of the present application, a first slide rail 11 is arranged at each of the two side positions of the second moving frame 70, and the second moving frame 70 has a sliding fit with the first slide rails 11 on its two sides. Arranging a first slide rail 11 on both sides of the second moving frame 70 can make the movement of the second moving frame 70 more stable and smooth.

[0047] Furthermore, the fixed frame 10 is provided with a first belt mechanism 20 on at least one side of the second moving frame 70. The first belt mechanism 20 includes first pulleys 21 located at both ends of itself and a first belt 22 wound around the first pulleys 21, and the first belt 22 extends in the same direction as the first slide rail 11; the first belt 22 is a toothed belt. The second moving frame 70 is connected to the first belt 22; the first drive source 50a can drive the first pulley 21 to rotate, enabling the second moving frame 70 to move in the first direction x following the first belt 22.

[0048] Specifically, a first pulley 21 is provided at each end of the first belt mechanism 20, and the first belt 22 is wound around the first pulleys 21 at both ends. When the first driving source 50a drives the first pulley 21 to rotate, the first belt 22 operates accordingly. Since the second moving frame 70 is connected to the first belt 22, the first belt 22 drives the second moving frame 70 to move in the first direction x. Further, the first belt 22 is a toothed belt, and the first belt 22 meshes with the first pulley 21, which can avoid slippage and inaccurate positioning.

[0049] For further reference Figure 2 , the fixing frame 10 arranges a first belt mechanism 20 on both sides of the second moving frame 70; the first pulleys 21 of the first belt mechanisms 20 on both sides are connected by a synchronous shaft 30, so as to synchronously drive the second moving frame 70 to move. A synchronous shaft 30 is arranged between the first pulleys 21 on both sides for connection, which can enable the first belt mechanisms 20 on both sides to operate synchronously, so as to synchronously drive both ends of the second moving frame 70 to move, and the operation is more stable.

[0050] In an embodiment of the present application, a second belt mechanism 80 is arranged on the second moving frame 70; the second belt mechanism 80 includes second pulleys 81 located at both ends of itself and a second belt 82 wound around the second pulleys 81, and the second belt 82 extends in the same direction as the second slide rail 71; the second belt 82 is a toothed belt. The first moving frame 41 is connected to the second belt 82; the second driving source 50b can drive the second pulley 81 to rotate, so that the first moving frame 41 moves in the second direction y following the second belt 82.

[0051] Specifically, a second pulley 81 is provided at each end of the second belt mechanism 80, and the second belt 82 is wound around the second pulleys 81 at both ends. When the second driving source 50b drives the second pulley 81 to rotate, the second belt 82 operates accordingly. Since the first moving frame 41 is connected to the second belt 82, the second belt 82 drives the first moving frame 41 to move in the second direction y. Further, the second belt 82 is a toothed belt, and the second belt 82 meshes with the second pulley 81, which can avoid slippage and inaccurate positioning.

[0052] In an embodiment of the present application, a first initial position sensor and a first end position sensor are arranged on the fixing frame 10, which are used to respectively sense and locate the starting position and the end position of the second moving frame 70 on the first slide rail 11. A second initial position sensor and a second end position sensor are arranged on the second moving frame 70, which are used to respectively sense and locate the starting position and the end position of the first moving frame 41 on the second slide rail 71.

[0053] Specifically, the first initial position sensor is used to sense the starting position of the second moving frame on the first slide rail, so that the controller can control the first drive source to drive the second moving frame to move based on the initial position calibrated by the first initial position sensor. The second initial position sensor is used for the starting position of the first moving frame on the second slide rail, so that the controller can control the second drive source to drive the first moving frame to move based on the initial position calibrated by the second initial position sensor.

[0054] In summary, the movement detection component is driven by the first drive source and the second drive source, and can move along the first direction and the second direction perpendicular to each other. The first drive source is a servo motor or a stepper motor, and the second drive source is a servo motor or a stepper motor. In the first direction and the second direction, the detection position of the movement detection component can be flexibly adjusted. Therefore, the movement detection path of the movement detection component can be adjusted as needed to adapt to different single-tube arrangement methods.
