Description

Technical Field

[0001] This invention relates to the field of pyrotechnic assembly technology, and more specifically to an automated pyrotechnic assembly system. Background Technology

[0002] Pyrotechnics refer to a general term for disposable components and devices containing gunpowder or explosives that, upon external stimulation, will burn or explode to ignite the gunpowder, detonate the explosive, or perform mechanical work. Currently, the production and assembly of pyrotechnics suffers from low automation, relying primarily on manual, discrete assembly. This results in low efficiency, weak production control in the workshop, and significant challenges in ensuring production consistency and quality. Furthermore, the assembly process involves numerous steps, making operations complex and inefficient, ultimately leading to low overall production line efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automated assembly system for pyrotechnic products to solve the aforementioned technical problems.

[0004] This invention provides an automated assembly system for pyrotechnic devices, including an automatic feeding and conveying device, a gas generator assembly device, and a gas cylinder assembly device. The automatic feeding and conveying device is used to store parts to be assembled in a temporary storage area or to send parts from the temporary storage area to the gas generator assembly device and the gas cylinder assembly device. The gas generator assembly device is used to assemble various parts to be assembled to form a piston rod assembly and a gas generator body. The gas cylinder assembly device is used to assemble various parts to be assembled, the piston rod assembly, and the gas generator body to form a pyrotechnic device power unit. The gas generator assembly device includes a gripping and tightening combined assembly and an assembly displacement assembly. The assembly and positioning assembly includes a first assembly base and a second assembly base. The multi-axis linkage robot is positioned to the side of the first assembly base, and a gripping and tightening joint assembly is mounted above the second assembly base. The gripping and tightening joint assembly is used to assemble the gas generator body on the second assembly base, and the multi-axis linkage robot is used to assemble the piston rod assembly on the first assembly base. The assembly and positioning assembly also includes a loading and rotating mechanism mounted on the first assembly base. The loading and rotating mechanism is used to clamp the piston rod assembly and the gas generator body, and drive the piston rod assembly to rotate around its centerline. The pyrotechnic power unit mainly consists of a gas cylinder assembly, a piston rod assembly, and a gas generator body. The assembly process of the piston rod assembly and the gas generator body, as well as the assembly process between them, are completed by the gas generator assembly device. Then, the gas cylinder assembly device assembles the gas cylinder assembly and combines it with the above structures to form the pyrotechnic power unit.

[0005] Preferably, the loading and rotating mechanism includes a fixed support structure, a rotating clamping structure, and a power structure connecting the rotating clamping structure, all disposed on a first assembly base. The piston rod assembly is mounted on the rotating clamping structure, and the rotating clamping structure is supported on the fixed support structure. The power structure drives the rotating clamping structure to slide along the fixed support structure, causing the piston rod assembly to rotate around its centerline. When driven by the power structure, the rotating clamping structure enables the piston rod assembly mounted within it to complete the assembly process, i.e., to rotate around its centerline. The fixed support structure provides space for the rotating clamping structure, ensuring its structural strength during rotation and thus guaranteeing its operational reliability.

[0006] Preferably, the fixed support structure includes a mounting bracket disposed on the first assembly base. A first support ring bracket and a second support ring bracket, respectively, are fixed to the left and right sides of the top surface of the mounting bracket. A plurality of first rolling elements are evenly arranged circumferentially on the end face of the first support ring bracket, and a plurality of second rolling elements are evenly arranged circumferentially on the end face of the second support ring bracket. The first and second rolling elements are engaged within the rotating clamping structure. The arrangement of the first and second support ring brackets provides, on the one hand, a mounting area for the evenly arranged first and second rolling elements along the circumferential direction, ensuring that the rotating clamping structure can slide on the plurality of first and second rolling elements, achieving stable and reliable rotation. On the other hand, it allows the long, strip-shaped piston rod assembly to pass through the first and second support ring brackets, thereby facilitating assembly operations and improving assembly efficiency.

[0007] Preferably, the rotating clamping structure includes a first rotating ring and a second rotating ring, with a connecting frame fixed between the first rotating ring and the second rotating ring. At least two clamping seats are fixed on the top surface of the connecting frame, and the piston rod assembly passes through the two clamping seats. The first rotating ring has a first annular track on its sidewall, in which the first rolling element is clamped. The second rotating ring has a second annular track on its sidewall, in which the second rolling element is clamped. The centerline of the piston rod assembly, the centerline of the first rotating ring, and the centerline of the second rotating ring are collinear. The power structure is used to drive the first rotating ring and the second rotating ring to rotate around their centerlines. A connecting frame is provided between the first and second rotating rings to ensure they are connected as a single unit and can move together. It also provides a sufficiently large mounting surface for mounting the clamping seat, reliably loading and clamping the piston rod assembly. This ensures that the center lines of the piston rod assembly, the first rotating ring, and the second rotating ring are collinear. When the first and second rotating rings are driven to rotate by the power structure, the piston rod assembly will also rotate around its center line. Furthermore, a first annular track and a second annular track are provided on the first and second rotating rings, allowing the first and second rolling elements to engage. The first annular track contacts multiple first rolling elements, and the second annular track contacts multiple second rolling elements, achieving multi-point rolling friction. In summary, this structure ensures the rotational stability and trajectory uniqueness of the first and second rotating rings, thereby guaranteeing the rotational accuracy of the piston rod assembly. Simultaneously, the entire rotating clamping structure is compact, the piston rod assembly is subjected to uniform force, and assembly reliability is significantly improved.

[0008] Preferably, the outer wall of the first or second rotating ring has a toothed groove, and the power structure includes a power unit and a gear body connected to the power unit, the gear body meshing with the toothed groove. Through the meshing of the gear body and the toothed groove, the power unit drives the gear body to rotate, which in turn drives the first and second rotating rings to rotate.

[0009] Preferably, a support seat is provided between the two clamping seats, and the piston rod assembly is mounted on the support seat. The support seat can provide a certain degree of support for the piston rod assembly, ensuring its rotational stability and reducing the impact of gravity on the rotational assembly process.

[0010] Preferably, the top of the first support ring frame, the first rotating ring, the second rotating ring, and the second support ring frame are provided with notches. The notches facilitate the entry of a multi-axis linkage robot or other strip-shaped parts into the center of the first support ring frame, the first rotating ring, the second rotating ring, and the second support ring frame.

[0011] Preferably, the automatic feeding and conveying device includes an input tooling plate, an automated shelf, and a transfer machine. The input tooling plate is mainly used to place all the parts to be used, and then the parts are transported to the automated shelf by high-precision conveying, and then temporarily stored on the automated shelf. When assembly operations are required, the transfer machine removes multiple parts from the automated shelf and sends them to the gas generator assembly device, gas cylinder assembly device, or other processes.

[0012] Preferably, it also includes a test module, which is used to perform push-pull tests and electrical performance tests on the power device of the pyrotechnic device.

[0013] Preferably, it also includes a remote monitoring module, which includes a field video acquisition module, a monitoring backend module, a storage module, and a remote monitoring terminal module.

[0014] Compared with the prior art, the automated assembly system for pyrotechnic products of this application has at least the following advantages:

[0015] In this invention, the entire gas generator assembly device consists of a gripping and tightening joint assembly, an assembly positioning assembly, and a multi-axis linkage robot. The gripping and tightening joint assembly sequentially clamps and feeds each component (igniter, sealing ring, adapter, pressure ring, rectifier, and plug) into a chuck above the second assembly base of the assembly positioning assembly. A dedicated tightening structure inside completes the tightening assembly operation. Combined with adhesive and oiling tools, the gas generator body is ultimately formed. The entire process is automated, resulting in high production efficiency and precision. It is controlled by a dedicated control system. Simultaneously, a loading and rotating mechanism is installed on the first assembly base. With the assistance of the multi-axis linkage robot, the piston rod assembly is assembled, aligning the assembled gas generator body with the piston rod assembly. The loading and rotating mechanism then rotates itself to drive the piston rod assembly to rotate around its centerline, allowing the threads on the piston rod assembly to engage with the threads inside the gas generator body. This quickly and reliably completes the assembly. After assembly, the multi-axis linkage robot extracts the components and transfers them to the next process. The entire process is automated, further improving production efficiency and precision. Attached Figure Description

Therefore, they should not be construed as limiting the present invention.

[0028] like Figures 1 to 5 As shown, this invention provides an automated assembly system for pyrotechnic devices, including an automatic feeding and conveying device, a gas generator assembly device, and a gas cylinder assembly device. The automatic feeding and conveying device is used to store parts to be assembled in a temporary storage area or to send parts in the temporary storage area to the gas generator assembly device and the gas cylinder assembly device. The gas generator assembly device is used to assemble various parts to be assembled to form a piston rod assembly 4 and a gas generator body. The gas cylinder assembly device is used to assemble various parts to be assembled, the piston rod assembly 4, and the gas generator body to form a pyrotechnic device power unit. The gas generator assembly device includes a gripping and tightening combined assembly 1, an assembly displacement assembly 2, and multiple... The multi-axis linkage robot 3 and the assembly displacement assembly 2 include a first assembly base 21 and a second assembly base 22. The multi-axis linkage robot 3 is located on the side of the first assembly base 21, and the gripping and tightening joint assembly 1 is mounted above the second assembly base 22. The gripping and tightening joint assembly 1 is used to assemble the gas generator body on the second assembly base 22, and the multi-axis linkage robot 3 is used to assemble the piston rod assembly 4 on the first assembly base 21. The assembly displacement assembly 2 also includes a loading and rotating mechanism 23 located on the first assembly base 21. The loading and rotating mechanism 23 is used to clamp the piston rod assembly 4 and the gas generator body, and drive the piston rod assembly 4 to rotate around its center line.

[0029] In this embodiment, it should be noted that the pyrotechnic power unit mainly consists of a gas cylinder assembly, a piston rod assembly 4, and a gas generator body. The assembly processes of the piston rod assembly 4 and the gas generator body, as well as the assembly processes between them, are all completed by the gas generator assembly device. Then, the gas cylinder assembly device assembles the gas cylinder assembly and combines it with the aforementioned structure to form the pyrotechnic power unit. The entire gas generator assembly device consists of a gripping and tightening joint assembly 1, an assembly displacement assembly 2, and a multi-axis linkage robot 3. The gripping and tightening joint assembly 1 sequentially clamps and feeds each component (igniter, sealing ring, adapter, pressure ring, rectifier, plug) into the chuck above the second assembly base 22 of the assembly displacement assembly 2, and completes the tightening assembly operation through its internal dedicated tightening structure. Combined with adhesive and oiling tools, the gas generator body is finally formed. The entire process is automated, with high production efficiency and high production precision, and is automatically controlled by a dedicated control system. At this time, a loading and rotating mechanism 23 is set on the first assembly base 21. With the cooperation of the multi-axis linkage robot 3, the piston rod assembly 4 is assembled and the assembled gas generator body is aligned with the piston rod assembly 4. At this time, the loading and rotating mechanism 23 uses its own rotation to drive the piston rod assembly 4 to rotate around its center line, so that the thread on the piston rod assembly 4 is screwed into the thread in the gas generator body, and the assembly operation is completed quickly and reliably. After the assembly is completed, the multi-axis linkage robot 3 pulls it out and transfers it to the next process. The whole process is automated, which further improves production efficiency and production accuracy.

[0030] Specifically, the loading and rotating mechanism 23 includes a fixed support structure 231, a rotating clamping structure 232, and a power structure 233 connected to the rotating clamping structure 232, all mounted on the first assembly base 21. The rotating clamping structure 232 is mounted on the piston rod assembly 4, the rotating clamping structure 232 is mounted on the fixed support structure 231, and the power structure 233 is used to drive the rotating clamping structure 232 to slide along the fixed support structure 231 so that the piston rod assembly 4 rotates around its centerline.

[0031] In this embodiment, it should be noted that after the rotating clamping structure 232 is driven by the power structure 233, it enables the piston rod assembly 4 installed inside it to complete the assembly operation, that is, to make the piston rod assembly 4 rotate around its center line; the fixed support structure 231 provides the mounting space for the rotating clamping structure 232, ensuring the structural strength of the rotating clamping structure 232 during the rotation process, thereby ensuring its motion reliability.

[0032] Specifically, the fixed support structure 231 includes a mounting frame 2311 disposed on the first assembly base 21. A first support ring frame 2312 and a second support ring frame 2313 in annular shape are fixed on the left and right sides of the top surface of the mounting frame 2311, respectively. A plurality of first rolling elements 2314 are evenly disposed on the end face of the first support ring frame 2312 in a circumferential direction. A plurality of second rolling elements 2315 are evenly disposed on the end face of the second support ring frame 2313 in a circumferential direction. The first rolling elements 2314 and the second rolling elements 2315 are engaged in the rotating clamping structure 232.

[0033] In this embodiment, it should be noted that the arrangement of the first support ring 2312 and the second support ring 2313 provides, on the one hand, an installation area for the first rolling elements 2314 and the second rolling elements 2315 that are evenly arranged along the circumferential direction, ensuring that the rotating clamping structure 232 can slide on the multiple first rolling elements 2314 and the multiple second rolling elements 2315 to complete a stable and reliable rotation. On the other hand, it allows the long strip-shaped piston rod assembly 4 to pass through the first support ring 2312 and the second support ring 2313, thereby facilitating assembly operations and improving assembly efficiency.

[0034] Specifically, the rotating clamping structure 232 includes a first rotating ring 2321 and a second rotating ring 2322. A connecting frame 2323 is fixed between the first rotating ring 2321 and the second rotating ring 2322. At least two clamping seats 2324 are fixed on the top surface of the connecting frame 2323. A piston rod assembly 4 passes through the two clamping seats 2324. The first rotating ring 2321 has a first annular track on its side wall, and a first rolling element 2314 is clamped in the first annular track. The second rotating ring 2322 has a second annular track on its side wall, and a second rolling element 2315 is clamped in the second annular track. The center line of the piston rod assembly 4, the center line of the first rotating ring 2321, and the center line of the second rotating ring 2322 are collinear. The power structure 233 is used to drive the first rotating ring 2321 and the second rotating ring 2322 to rotate around their center lines.

[0035] In this embodiment, it should be noted that a connecting frame 2323 is provided between the first rotating ring 2321 and the second rotating ring 2322 to ensure that the two are connected as one and can move together. It also provides a sufficiently large mounting surface for mounting the clamping seat 2324 to reliably load and clamp the piston rod assembly 4, ensuring that the center line of the piston rod assembly 4, the center line of the first rotating ring 2321, and the center line of the second rotating ring 2322 are collinear. After the first rotating ring 2321 and the second rotating ring 2322 are driven to rotate by the power structure 233, the piston rod assembly 4 will also rotate around its center line. Furthermore, the first rotating ring 2321... A first annular track and a second annular track are provided on the first rotating ring 2321 and the second rotating ring 2322, allowing the first rolling element 2314 and the second rolling element 2315 to be respectively engaged. The first annular track contacts multiple first rolling elements 2314, and the second annular track contacts multiple second rolling elements 2315, realizing multi-point rolling friction. In summary, the above structure can ensure the rotational stability and trajectory uniqueness of the first rotating ring 2321 and the second rotating ring 2322, thereby ensuring the rotational accuracy of the piston rod assembly 4. At the same time, the entire rotating clamping structure 232 is compact, the piston rod assembly 4 is subjected to uniform force, and the assembly reliability is greatly improved.

[0036] Specifically, the outer wall of the first rotating ring 2321 or the second rotating ring 2322 is provided with tooth grooves, and the power structure 233 includes a power unit 2331 and a gear body 2332 connected to the power unit 2331, with the gear body 2332 meshing with the tooth grooves.

[0037] In this embodiment, it should be noted that, through the meshing of the gear body 2332 and the tooth groove, after the power unit 2331 drives the gear body 2332 to rotate, it can drive the first rotating ring 2321 and the second rotating ring 2322 to rotate.

[0038] Specifically, a support seat 2325 is provided between the two clamping seats 2324, and a piston rod assembly 4 is mounted on the support seat 2325.

[0039] In this embodiment, it should be noted that the support base 2325 can provide a certain degree of support for the piston rod assembly 4, ensuring its rotational stability and reducing the impact of gravity on the rotational assembly process.

[0040] Specifically, the first support ring 2312, the first rotating ring 2321, the second rotating ring 2322, and the second support ring 2313 have notches at their tops.

[0041] In this embodiment, it should be noted that the notch facilitates the entry of the multi-axis linkage robot 3 or other strip-shaped parts into the center of the first support ring 2312, the first rotating ring 2321, the second rotating ring 2322, and the second support ring 2313.

[0042] Specifically, the automated feeding and conveying system includes input tooling plates, automated racks, and transfer machines.

[0043] In this embodiment, it should be noted that the input tooling plate is mainly used to place all the parts to be used, and then the parts are transported to the automated shelf through high-precision conveying, and then temporarily stored on the automated shelf. When assembly is required, the transfer machine removes multiple parts from the automated shelf and sends them to the gas generator assembly device, gas cylinder assembly device or other processes.

[0044] Specifically, it also includes test modules, which are used to perform push-pull tests and electrical performance tests on the power devices of pyrotechnics.

[0045] Specifically, it also includes a remote monitoring module, which comprises a field video acquisition module, a monitoring backend module, a storage module, and a remote monitoring terminal module.
