Description

Technical Field

[0001] This utility model relates to the field of fireworks testing equipment technology, and in particular to a device for testing the filling effect of bright bead powder in the inner tube of fireworks. Background Technology

[0002] Fireworks, as a form of entertainment that produces sound, light, and color, are widely used in grand festivals, ceremonies, and performances. With the continuous improvement of people's living standards, the use of combination fireworks has also entered countless households. In the production process of combination fireworks, all procedures are operated and inspected manually. However, with increasing emphasis on production safety and improved production efficiency, current combination fireworks production has generally achieved semi-automated assembly line production, using a combination of human and machine methods for production and inspection.

[0003] One crucial step is inspecting the filling effect of the bright powder in the fireworks' inner tube. Traditionally, this is done by directly using a camera.

[0004] However, the filling site for the bright beads and powder in the fireworks' inner tube is often filled with dust (mainly containing powders containing easily explosive bright beads). This dust accumulates on the camera's surface, creating a vulnerable environment around the camera during operation. Short circuits or overheating during use increase the risk of explosion. Furthermore, to prevent dust residue from causing flammable and explosive situations, the equipment is thoroughly rinsed with water after each shift. This results in high humidity, which can cause fogging on the camera's lens, making testing impossible. The rinsing process can also lead to water ingress into the camera, affecting its lifespan.

[0026] Please see Figure 1 and Figure 2 The preferred embodiment of the firework inner tube bright bead powder filling effect detection device 100 includes a frame 110, a protective shell 120 and a detection camera 130.

[0027] The protective housing 120 is mounted on the frame 110. The sidewalls of the protective housing 120 have at least a portion of transparent windows 121. The protective housing 120 can be a fully transparent housing structure or a structure where only a portion is transparent and the rest is opaque.

[0028] An inspection camera 130 is installed inside the protective housing 120. The inspection lens of the inspection camera 130 is positioned facing the transparent window 121. The inspection camera 130 is used to inspect the filling effect of the bright bead powder in the inner tube of the fireworks located outside the protective housing 120. That is, the inspection lens of the inspection camera 130 is aligned with at least a portion of the transparent window 121.

[0029] The inner tube of the fireworks located outside the protective shell 120 can be located on the frame 110 at a position that can be detected by the detection camera 120, or it can be located at other positions independent of the fireworks inner tube bright bead powder filling effect detection device 100, such as other production lines or independent belt conveyor mechanisms at a position that can be detected by the detection camera 130, or on the ground or other objects that can be detected by the detection camera.

[0030] The aforementioned fireworks inner tube bright bead powder filling effect detection device 100 houses a detection camera 130 within a protective casing 120. The camera 130 can inspect the fireworks inner tube located outside the protective casing 120 through a transparent viewing window 121. The protective casing 120 prevents dust from the surrounding environment from spreading to the camera 130, reducing the probability of on-site combustion or explosion caused by short circuits or overheating during camera 130 use, thus improving detection safety. Furthermore, due to the protective function of the casing 120, water is prevented from entering the camera 130 during the overall equipment rinsing after each shift, effectively ensuring the lifespan of the camera 130. Furthermore, the high humidity at the site caused by rinsing the equipment is a significant concern. The protective casing 120 prevents moisture from the surrounding environment from entering the detection camera 130 and avoids fogging on the lens of the detection camera 130. Even if fog forms on the transparent window 121, a simple wiping action is sufficient to ensure that the detection camera 130 can accurately detect the inner tube of the fireworks located outside the protective casing 120, thus improving the reliability of the detection work. Therefore, the aforementioned fireworks inner tube bright bead powder filling effect detection device 100 not only improves the safety and reliability of the detection work but also extends the service life of the detection camera 130.

[0031] In one embodiment of this utility model, the protective shell 120 includes a metal shell 122 and a transparent plate (not shown) serving as a transparent viewing window 121. A detection window 1221 is provided on the side wall of the metal shell 122. The transparent plate is fixed to the metal shell 122 and covers and seals the detection window 1221. Thus, by configuring the protective shell 120 with a metal shell 122 and a transparent plate, the protective shell 120 can ensure high structural strength while also ensuring that the detection camera 130 inside the protective shell 120 can accurately detect the inner tube of the fireworks outside the protective shell 120.

[0032] In another embodiment of this utility model, the protective shell 120 is composed of multiple glass plates spliced ​​together. Therefore, the protective shell 120 has a completely transparent structure. Not only can the detection camera 130 inside the protective shell 120 directly inspect the inner tube of the fireworks located outside the protective shell 120 through the glass plates, but also personnel can quickly observe the situation inside the protective shell 120 without opening it. This facilitates quick identification of the cause of any malfunctions, such as short circuits in the detection camera 130.

[0033] In some embodiments, the protective housing 120 includes an upper housing 1222 with one open end and a lower housing 1223 with one open end. The open end of the upper housing 1222 is overhanged onto the open end of the lower housing 1223, and the two are detachably connected. The upper housing 1222 is detachably mounted on the frame 110. The sidewall of the lower housing 1223 has at least a portion of a transparent window 121. By configuring the protective housing 120 into an upper housing 1222 and a lower housing 1223, and detachably connecting the two, during the assembly of the fireworks inner tube bright bead powder filling effect detection device 100, the upper housing 1222 can be installed on the frame 110 first, and then the detection camera 130 can be installed inside the upper housing 1222 or the lower housing 1223, and then the lower housing 1223 can be installed on the upper housing 1222. Compared with the method of first installing the camera inside the protective housing 120 and then installing the entire protective housing 120 onto the frame 110, the assembly difficulty is greatly reduced. Moreover, configuring the protective housing 120 into a detachably connected upper housing 1222 and lower housing 1223 facilitates the disassembly, assembly, and maintenance of structures such as the detection camera 130 inside the protective housing 120.

[0034] Specifically, when the protective shell 120 includes a metal shell 122 and a transparent plate, the metal shell 122 includes an upper shell 1222 and a lower shell 1223. The bottom of the lower shell 1223 has a detection window 1221 that penetrates the side wall. The transparent plate is installed on the lower shell 1223 and covers and seals the transparent window.

[0035] In some embodiments, the frame 110 has a mounting rod 111. A mounting base 140 is detachably mounted on the mounting rod 111. The mounting base 140 is operably slidable along the mounting rod 111. A protective housing 120 is detachably mounted on the mounting base 140. The mounting rod 111 is horizontally positioned on the frame 110, or slightly inclined relative to the horizontal plane. In practical applications, the axial mounting position of the detection camera 130 on the mounting rod 111 is adjusted by sliding the mounting base 140 on the mounting rod 111 and tightening it after it has slid into place.

[0036] During equipment debugging, based on the specific location of the inner tube of the fireworks during testing, the position of the mounting base 140 on the mounting rod 111 is adjusted to achieve axial adjustment of the detection camera 130 on the mounting rod 111. This ensures that the detection camera 130 can accurately and comprehensively detect the inner tube of the entire fireworks sphere 10, further improving the reliability of the detection of the filling effect of the bright bead powder in the inner tube of the fireworks.

[0037] Furthermore, in some embodiments, there are multiple mounting rods 111. The multiple mounting rods 111 are arranged parallel to each other and spaced apart in a direction perpendicular to the mounting rods 111. The mounting base 140 can be selectively mounted on one of the multiple mounting rods 111.

[0038] When the fireworks inner tube bright bead powder filling effect detection device 100 is located on a horizontal plane, the axial direction of the mounting rod 111 and the spacing direction of the multiple mounting rods 111 are two mutually perpendicular horizontal directions. Thus, by selecting a method to mount the detection camera 130 on different mounting rods 111, the installation position of the detection camera 130 in the spacing direction of the multiple mounting rods 111 can be adjusted. This further ensures that the detection lens of the detection camera 130 is directly facing the fireworks sphere 10 located outside the protective shell 120, further ensuring that the detection camera 130 can perform comprehensive and accurate detection of the fireworks sphere 10 located outside the protective shell 120, and further improving the reliability of the fireworks inner tube bright bead powder filling effect detection.

[0039] In some embodiments, a mounting bracket 150 is provided inside the protective housing 120. The detection camera 130 is suspended and mounted on the mounting bracket 150. Suspending the detection camera 130 inside the protective housing 120 avoids direct contact between the lens of the detection camera 130 and the transparent window 121, thereby preventing frequent collisions between the detection camera 130 and the transparent window 121 due to vibration of the entire device, which could scratch the transparent window 121 or damage the lens of the detection camera 130. This further extends the service life of the fireworks inner tube bright bead powder filling effect detection device 100.

[0040] Furthermore, in some embodiments, the mounting bracket 150 includes a plurality of support rods 151, a connecting plate 152, and a mounting vertical plate 153. One end of each of the support rods 151 is fixed to the bottom inside the protective housing 120, and the other end is connected to the connecting plate 152. The mounting vertical plate 153 is fixed to the side of the connecting plate 152 facing the support rods 151. The detection camera 130 is detachably mounted on the mounting vertical plate 153.

[0041] Thus, the mounting bracket 150 is configured with multiple support rods 151, connecting plates 152 and mounting vertical plates 153 to ensure that the mounting bracket 150 is fixed to the bottom inside the protective shell 120 and to ensure the structural stability of the mounting bracket 150. At the same time, the mounting vertical plate 153 is set below the connecting plate 152 to ensure that the detection camera 130 can be suspended inside the protective shell 120 near the transparent window 121.

[0042] When the protective housing 120 includes an upper housing 1222 and a lower housing 1223, one end of the support rod 151 is fixed to the bottom inside the lower housing 1223, thereby fixing the mounting bracket 150 inside the lower housing 1223. This allows the installation of the inspection camera 130 inside the lower housing 1223 to be completed on the ground, further reducing the assembly difficulty.

[0043] Furthermore, in some embodiments, the fireworks inner tube bright bead powder filling effect detection device 100 also includes a connector (not shown). An elongated through hole 1531 is provided on the mounting vertical plate 153 along the direction from the connecting plate 152 to the mounting vertical plate 153. One end of the mounting vertical plate 153 passes through the elongated through hole 1531, and the other end is detachably connected to the detection camera 130, so that the detection camera 130 is detachably connected to the mounting vertical plate 153. The elongated through hole 1531 and the connector allow for vertical adjustment of the installation position of the detection camera 130, further improving the detection accuracy of the detection camera 130 in detecting the fireworks inner tube located outside the protective shell 120.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
