Description

Technical Field

[0001] This utility model belongs to the technical field of fireworks production equipment, specifically relating to a visual inspection device for emitted fireworks. Background Technology

[0002] Fireworks, as a product with ornamental value and cultural significance, rely heavily on the uniformity of the proportion and particle distribution of the firing powder in traditional fireworks manufacturing processes, which directly affect the product's launch height and stability. Currently, the industry commonly uses manual sampling or simple mechanical sieving, which suffers from low detection efficiency and insufficient accuracy. Traditional detection methods require highly skilled operators and pose safety hazards during the process. Existing detection equipment is mostly based on weighing or vibrating screen principles, making it difficult to accurately identify the particle shape and distribution uniformity of the firing powder, and it cannot achieve real-time online detection during the production process. Some optical detection solutions are complex and costly, making them unsuitable for large-scale industrial production. Therefore, there is an urgent need for a visual inspection device for firing powder to solve these problems. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a visual inspection device for emission of nitrous oxide.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: A visual inspection device for firing nitrous oxide includes a frame, a visual inspection mechanism is mounted on the top of the frame, a conveyor lifting line is mounted on the lower inner side of the frame, and a work tray is slidably mounted on the conveyor lifting line. The visual inspection mechanism includes a mounting plate mounted on top of a frame. A telescopic screw is mounted at the center of the top of the mounting plate. A servo motor is mounted at the top input end of the telescopic screw, and a push rod is connected to the bottom power output end of the telescopic screw. The bottom of the push rod passes through the mounting plate and extends to its lower side. A camera mounting plate is mounted at the bottom of the push rod. The camera mounting plate has four sets of pre-drilled holes. A visual camera is mounted at the corresponding four sets of pre-drilled holes on the camera mounting plate. A light source plate is mounted at the bottom of the camera mounting plate. Guide posts are mounted on the four sides of the top of the camera mounting plate, and the tops of the guide posts pass through the mounting plate and extend to its upper side.

[0005] Furthermore, a camera mounting bracket is mounted on the surface of the camera mounting plate, and the vision camera is fixedly mounted on the camera mounting bracket. This structural design facilitates the installation, removal, and maintenance of the vision camera.

[0006] Furthermore, the mounting plate has a guide seat installed at the through-hole of the guide post, the guide post is slidably disposed within the guide seat, and limit frames are installed on the top of the four guide posts. This structural design further improves the guiding and sliding effect and also has a limiting effect.

[0007] Further specifying, the working tray includes a tooling plate, which is slidably disposed on the conveyor lifting line. A limit tray is installed on the top of the tooling plate, and a plurality of cartridge cases are installed within the limit tray. This structural design facilitates the installation and conveying of cartridge cases.

[0008] Furthermore, the conveyor lifting line includes a conveyor line located inside the lower side of the frame, with a lifting device installed directly below the vision inspection mechanism, and a blocking device installed on one side of the lifting device. This structural design facilitates the limiting, blocking, and lifting of the work tray.

[0009] The beneficial effects of this utility model are as follows: By setting up a visual inspection mechanism, this utility model significantly improves the quality inspection level of fireworks and firecrackers. By analyzing the particle morphology and distribution uniformity in real time, it overcomes the limitations of traditional manual sampling and mechanical sieving. The detection accuracy is much higher than that of traditional manual inspection methods. At the same time, it avoids the high cost of existing optical inspection solutions. The online inspection design realizes real-time quality control of the production process, greatly improves the inspection efficiency, avoids the risk of human contact with hazardous materials, significantly improves operational safety, and achieves efficient, accurate, and low-cost automated inspection, thereby improving production safety and quality control levels.

[0011] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Example 1, such as Figure 1 and Figure 2 As shown, a visual inspection device for firing nitrous oxide has a visual inspection mechanism 1 installed on the top of the frame 4, a conveyor lifting line 3 installed on the lower inside of the frame 4, and a work tray 2 slidably mounted on the conveyor lifting line 3. The visual inspection mechanism 1 includes a mounting plate 13, which is mounted on the top of the frame 4. A telescopic screw 12 is mounted at the top center of the mounting plate 13. A servo motor 11 is mounted at the top input end of the telescopic screw 12. A push rod 18 is connected to the bottom power output end of the telescopic screw 12. The bottom of the push rod 18 passes through the mounting plate 13 and extends to its lower side. A camera mounting plate 16 is mounted at the bottom of the push rod 18. The camera mounting plate 16 has four sets of reserved holes 19. A visual camera 14 is mounted at the corresponding four sets of reserved holes 19 on the camera mounting plate 16. A light source plate 15 is mounted at the bottom of the camera mounting plate 16. Guide posts 17 are mounted on the four sides of the top of the camera mounting plate 16. The top of the guide posts 17 passes through the mounting plate 13 and extends to its upper side.

[0013] In this embodiment, during use, the conveyor lifting line 3 moves the work tray 2 to below the vision inspection mechanism 1. The conveyor lifting line 3 then lifts the work tray 2 upwards to perform the firing detection process. Simultaneously, the vision inspection mechanism 1 starts working, and the servo motor 11 drives the telescopic screw 12, causing the telescopic screw 12 to extend and retract the push rod 18. This causes the push rod 18 to move the camera mounting plate 16 up and down. During the movement, the camera mounting plate 16 causes the guide column 17 to slide on the mounting plate 13, thus ensuring the verticality of the movement. The moving camera mounting plate 16 causes the vision camera 14 and the light source plate 15 to adjust their height, thereby allowing the vision camera 14 to adapt to the height of different types of products. At the same time, the light source plate 15 provides supplementary lighting. Through the four vision cameras 14, the entire contents of the cartridge 21 can be accurately and completely detected, improving the detection effect. After the detection is completed, the conveyor lifting line 3 lowers the work tray 2 and transports it to the subsequent work station along the conveyor lifting line 3.

[0014] Example 2, as Figure 2As shown, this embodiment adds the following structure to the embodiment 1: a camera mounting bracket 110 is mounted on the surface of the camera mounting plate 16, and the vision camera 14 is fixedly mounted on the camera mounting bracket 110.

[0015] In this embodiment, the vision camera 14 can be quickly and easily installed using the camera mounting bracket 110, and can be easily disassembled for subsequent maintenance.

[0016] Example 3, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the mounting plate 13 is equipped with a guide seat 111 at the through-hole of the guide post 17, the guide post 17 is slidably disposed in the guide seat 111, and a limit frame 112 is installed on the top of the four guide posts 17.

[0017] In this embodiment, during use, the camera mounting plate 16 will drive the guide column 17 as it moves. The guide column 17 slides vertically along the guide seat 111 and simultaneously drives the limiting frame 112. While ensuring the effect of vertical movement, the limiting frame 112 can also play a limiting role.

[0018] Example 4, as Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the working tray 2 includes a tooling plate 23, which is slidably disposed on the conveying lifting line 3. A limiting tray 22 is installed on the top of the tooling plate 23, and a plurality of cartridges 21 are installed inside the limiting tray 22.

[0019] In this embodiment, during installation, several cartridge cases 21 are vertically placed above the limiting tray 22, the limiting tray 22 is installed on the tooling plate 43, and the tooling plate 43 moves along the conveying lifting line 3.

[0020] The tooling plate 43 has pin holes around its perimeter for positioning.

[0021] Example 5, as Figure 4 As shown, this embodiment adds the following structure to embodiment 1: the conveyor lifting line 3 includes a conveyor line 31 located inside the lower side of the frame 4, a lifting device 33 installed directly below the vision inspection mechanism 1 on the conveyor line 31, and a blocking device 32 installed on one side of the lifting device 33 on the conveyor line 31. This structural design facilitates the limiting, blocking, and lifting of the work tray 2.

[0022] In this embodiment, during use, the tooling plate 43 carries the cartridge 21 and moves along the conveyor line 31. When the tooling plate 43 moves along the conveyor line 31 to the area directly below the vision inspection mechanism 1, the blocking device 32 extends and limits the tooling plate 43 to the area directly below the vision inspection mechanism 1. Then, the lifting device 33 is activated to lift the tooling plate 43 to perform the firing detection process. After completion, the lifting device 33 descends, the blocking device 32 retracts, and the tooling plate 43 carrying the cartridge 21 is transported along the conveyor line 31 to the subsequent work station.

[0023] The lifting device 33 has pins at the pin holes around the corresponding tooling plate 43 to achieve a fit and ensure the stability of the lifting operation.

[0024] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
