Description

Technical Field

[0001] This invention relates to the field of fire extinguishing device manufacturing technology, and more specifically, to a fire extinguishing device manufacturing system and its operating method. Background Technology

[0002] Fire extinguishing systems are commonly used firefighting equipment, and the sealing performance of their tanks and covers directly affects the product's reliability and safety. Mainstream products include various types such as cabinet-type heptafluoropropane systems, suspended ultrafine dry powder systems, and portable aerosol systems, all featuring automatic detection, rapid response, and high-efficiency fire extinguishing capabilities. Gaseous systems achieve oxygen isolation through total flooding spraying, dry powder systems utilize free radical blocking mechanisms, and aerosol systems combine particle coverage and cooling functions.

[0003] Currently, the manufacturing process of fire extinguishing devices largely relies on manual labor or semi-automatic equipment, which has several shortcomings. First, manual assembly is inefficient and makes it difficult to ensure the assembly precision of the tank and the lid, resulting in loose sealing and potential leaks later on. Second, the welding of the lid is mostly done manually, leading to inconsistent welding quality and a tendency for incomplete or missed welds. Third, production lines generally lack online inspection, and weld quality depends on manual visual inspection, making it difficult to detect micron-level cracks and pores, and thus failing to effectively remove defective products, posing serious safety hazards. Furthermore, existing equipment has poor adaptability to different product specifications, making changeovers difficult. Summary of the Invention

Its turntable is driven by the first servo motor. The limiting groove carries the tank and moves cyclically along the guide groove. The barrel feeding mechanism controls the three-jaw chuck to grab the tank from the support table through the first transverse electric rail and the first longitudinal cylinder and accurately place it on the turntable. The cover feeding mechanism sorts the covers through the feeding guide rail and the transfer table and moves them to the top of the tank by the first transporting claw.

The eddy current testing mechanism scans the weld seam. The second and third transverse electric rails drive the eddy current flaw detection head to move along the weld seam. Defects such as microcracks or pores are identified by electromagnetic induction. The sixth longitudinal cylinder adjusts the probe distance in real time to ensure the detection accuracy. Finally, the second transport gripper of the unloading mechanism picks up the finished product, and the second servo motor drives it to move to the unloading conveyor belt via the transmission belt, completing the production closed loop.

[0015] Beneficial effects: Compared with the prior art, the advantages of this invention are: (1) The present invention realizes multi-station flow through turntable mechanism, barrel feeding mechanism and lid feeding mechanism accurately position materials, pressing mechanism flexibly presses, welding mechanism laser seals, unloading mechanism automatically sorts, improves overall efficiency, at the same time, eddy current detection mechanism scans weld seam online to eliminate leakage risks, welding mechanism laser welding depth is controllable to ensure that the pressure resistance of fire extinguishing device meets national standards.

[0016] (2) The present invention adapts to different tank sizes through a three-jaw chuck and an adjustable pressing mechanism. The turntable limit groove can quickly switch product types. This solution replaces manual operation, reduces assembly damage, and the air guide hood ensures a clean welding environment and extends equipment life.

[0017] In summary, the advantages of this invention lie in its efficient multi-station workflow achieved through a turntable mechanism, integrating automatic feeding, laser welding, and online inspection functions to form a highly automated production system. Particularly noteworthy is its unique mechanical linkage design for the pressing mechanism, which transforms the vertical pressing action into a horizontal clamping action. A single power source can simultaneously complete the pressing of the top cover and the centering clamping of the tank body. This not only results in a compact structure and simple control but also ensures the precision and stability of the assembly process, avoids rigid impacts, and significantly improves the sealing quality of the product. Combined with the controllable depth of laser welding and online non-destructive testing using eddy current detection, this system fundamentally solves the problems of low efficiency, unstable quality, and safety hazards inherent in traditional production processes.

[0021] Example:

[0022] Please see Figure 1-9A manufacturing system for a fire extinguishing device and its operating method are disclosed, comprising: a processing table 1, a turntable mechanism 2 fixedly connected to the processing table 1, a barrel feeding mechanism 3 for feeding a tank body fixedly connected to the processing table 1, a cover feeding mechanism 4 for feeding a cover fixedly connected to the other side of the turntable mechanism 2, a pressing mechanism 5 adapted to the cover feeding mechanism 4 fixedly connected to the processing table 1, a welding mechanism 6 fixedly connected to one side of the turntable mechanism 2, an eddy current detection mechanism 7 fixedly connected to the welding mechanism 6, and a unloading mechanism 8 fixedly connected to one side of the welding mechanism 6.

[0023] Preferably, a cover feeding mechanism 4 for feeding the cover is fixedly connected to the processing table 1, and the cover feeding mechanism 4 is arranged around the turntable mechanism 2.

[0024] In a specific embodiment of the present invention, a turntable mechanism 2 enables multi-station flow, a barrel feeding mechanism 3 and a lid feeding mechanism 4 precisely position materials, a pressing mechanism 5 flexibly presses, a welding mechanism 6 performs laser sealing, and a discharging mechanism 8 automatically sorts materials, improving overall efficiency. An eddy current detection mechanism 7 scans welds online to eliminate potential leakage hazards. The laser welding depth of the welding mechanism 6 is controllable, ensuring that the pressure resistance of the fire extinguishing device meets national standards. The three-jaw chuck 306 and the adjustable pressing mechanism 5 are adapted to different tank sizes, and the turntable limiting groove 203 allows for quick switching of product types. This solution replaces manual operation, reduces assembly damage, and the air guide hood 609 removes dust to ensure a clean welding environment and extend equipment life.

[0025] Specifically, the turntable mechanism 2 includes a protective disk 201 fixedly connected to the upper surface of the processing table 1, a rotating disk 202 rotatably connected to the protective disk 201, a plurality of limiting grooves 203 arranged in a ring array on the rotating disk 202, a guide groove 204 on the protective disk 201, a first servo motor 205 fixedly connected to the protective disk 201, and the output shaft of the first servo motor 205 fixedly connected to the rotating disk 202.

[0026] In a specific embodiment of the present invention, the first servo motor 205 drives the rotating disk 202 to rotate on the protective disk 201, the limiting groove 203 fixes the tank, the guide groove 204 ensures accurate positioning of the workstation, the multi-workstation synchronous flow shortens the process interval, the protective disk 201 prevents external interference and improves the stability of the production line.

[0027] Preferably, the multiple limiting grooves 203 on the rotating disk 202 are used to accommodate and fix the tank, so that it rotates with the rotating disk 202; the guide groove 204 opened on the protective disk 201 cooperates with the positioning device (not shown in the figure) on the station to ensure that when the rotating disk 202 stops, the tank in the limiting groove 203 is precisely aligned with each processing station.

[0028] Specifically, the barrel feeding mechanism 3 includes a first feeding rack 301 fixedly connected to the processing table 1. A first transverse electric rail 302 for transverse adjustment is fixedly connected to the first feeding rack 301. A first transverse slide 303 is fixedly connected to the moving part of the first transverse electric rail 302. A first longitudinal slide 305 is slidably connected to the first transverse slide 303. A three-jaw chuck 306 is fixedly connected to the first longitudinal slide 305. A first longitudinal cylinder 304 is fixedly connected to the first transverse slide 303, and the piston rod of the first longitudinal cylinder 304 is fixedly connected to the first longitudinal slide 305. A support platform 307 is fixedly connected to the first feeding rack 301. A second longitudinal cylinder 308 for longitudinal adjustment is fixedly connected to the support platform 307. A first feeding plate 309 is fixedly connected to the piston rod of the second longitudinal cylinder 308.

[0029] In a specific embodiment of the present invention, the first transverse electric rail 302 and the first longitudinal cylinder 304 drive the three-jaw chuck 306 to grab the canister, and the second longitudinal cylinder 308 is positioned by the first feeding plate 309. The two cylinders work together to achieve three-dimensional precise feeding, and the support platform 307 avoids wear on the canister and is compatible with different specifications of fire extinguisher canisters.

[0030] Specifically, the loading mechanism 4 includes a feeding tray 401 and a second loading rack 403 fixedly connected to the processing table 1. A feeding guide rail 402 is fixedly connected to the feeding tray 401. A transfer table 404 is fixedly connected to the second loading rack 403. A first longitudinal electric rail 405 for longitudinal adjustment is fixedly connected to the second loading rack 403. A first transverse cylinder 406 is fixedly connected to the moving part of the first longitudinal electric rail 405. A first transport gripper 407 is fixedly connected to the piston rod of the first transverse cylinder 406.

[0031] In a specific embodiment of the present invention, the feeding guide rail 402 transports the top cover to the transfer table 404, and the first longitudinal electric rail 405 and the first transverse cylinder 406 drive the first transport gripper 407 to grab the top cover and transfer it to the tank, thereby reducing the risk of sealing failure caused by assembly deviation.

[0032] Specifically, the pressing mechanism 5 includes a pressing table 501 fixedly connected to the upper surface of the processing table 1. Two guide cylinders 502 are fixedly connected to the pressing table 501. A sliding seat 503 is slidably connected to the guide cylinder 502. An electromagnetic chuck 504 is rotatably connected to the sliding seat 503. In practice, a vacuum chuck can also be used instead of the electromagnetic chuck 504, which is also feasible.

[0033] An adjusting cylinder 505 is rotatably connected to the sliding seat 503, and the piston rod of the adjusting cylinder 505 is rotatably connected to the electromagnetic chuck 504. A mounting bracket 506 is fixedly connected to the pressing table 501, and a rotating component 507 is rotatably connected to the mounting bracket 506. An adjusting protrusion 508 is rotatably connected to the rotating component 507, and a connecting component 511 is rotatably connected to the adjusting protrusion 508. A guide plate 509 is fixedly connected to the sliding seat 503, and a curved groove 510 is provided on the guide plate 509. The adjusting protrusion 508 is slidably connected to the curved groove 510. Two horizontally extending first transverse guide rails are provided on the pressing table 501. 512, a second transverse slide block 513 is slidably connected to the first transverse guide rail 512, and a connecting piece 511 is rotatably connected to the second transverse slide block 513. Two second transverse cylinders 514 are fixedly connected to the pressing table 501. A spring telescopic rod 515 is fixedly connected to the inner end of the second transverse cylinder 514. A reinforcing plate 516 is fixedly connected to the spring telescopic rod 515. A third longitudinal cylinder 517 for longitudinal adjustment is fixedly connected to the bottom of the pressing table 501. A connecting horizontal plate 518 is fixedly connected to the piston rod of the third longitudinal cylinder 517, and both guide cylinders 502 are fixedly connected to the connecting horizontal plate 518.

[0034] In a specific embodiment of the present invention, the third longitudinal cylinder 517 serves as the initial power source, pushing the connecting horizontal plate 518 up and down via its piston rod, thereby causing the two guide cylinders 502 fixed thereon to rise and fall as a whole. Subsequently, the sliding seat 503 slides along the guide cylinder 502, and the electromagnetic chuck 504 on it generates magnetic force to attract the workpiece after being energized. The attraction angle can be dynamically adjusted by the adjusting cylinder 505. Since the piston rod of the adjusting cylinder 505 is rotatably connected to the electromagnetic chuck 504, its extension and retraction can drive the electromagnetic chuck 504 to rotate around the hinge point on the sliding seat 503 to adapt to uneven workpiece surfaces or specific tilt angle requirements. Secondly, the fine adjustment of the lateral position is achieved by a unique curved groove 510 and adjusting protrusion 508 linkage mechanism. When the rotating part 507 rotates, it drives the adjusting protrusion 508 on it to move. Since the adjusting protrusion 508 is slidably connected to the guide plate 509, Within the curved groove 510, the oblique trajectory of the curved groove 510 will convert the compound motion of the adjusting protrusion 508 into lateral displacement. The adjusting protrusion 508 pushes the second lateral slide block 513 to slide along the first lateral guide rail 512 through the connecting piece 511, thereby driving the entire slide block 503 and the electromagnetic chuck 504 to move laterally, so as to achieve precise centering of the workpiece position.

[0035] Specifically, when the third longitudinal cylinder 517 drives the sliding seat 503 to press down, the guide plate 509 fixed on the sliding seat 503 moves downward accordingly. Since the adjusting protrusion 508 is embedded in the curved groove 510 of the guide plate 509, the specific trajectory of the curved groove 510 forces the adjusting protrusion 508 to generate lateral displacement while moving downward, thereby driving the rotating component 507 to rotate around the mounting bracket 506. This rotation ultimately pushes the second transverse sliding seat 513 and the reinforcing plate 516 inward through the connecting component 511, thereby clamping the tank.

[0036] Preferably, the third longitudinal cylinder 517 serves as the initial power source. Its piston rod extends, pushing the connecting horizontal plate 518 downward, which in turn causes the two guide cylinders 502, which are fixedly connected to the connecting horizontal plate 518, to descend as a whole. Since the sliding seat 503 is slidably connected to the guide cylinder 502, the sliding seat 503 also descends synchronously with the guide cylinder 502, causing the electromagnetic chuck 504 on it to approach and eventually contact the top cover placed on the can. After the electromagnetic chuck 504 is energized and attracts the top cover, the third longitudinal cylinder 517 continues to apply pressure, pressing the top cover tightly against the can opening.

A gas guide seat 608 is fixedly connected to the bottom of the welding seat 602. A gas guide cover 609 is fixedly connected to the gas guide seat 608.

[0038] In a specific embodiment of the present invention, the fourth longitudinal cylinder 601 adjusts the height of the welding seat 602, the fifth longitudinal cylinder 605 controls the position of the laser emitting head 607, the air guide 609 blows away the welding fumes, the laser welding achieves high-precision sealing, the air guide 609 ensures the cleanliness of the weld and meets the pressure resistance requirements of the fire extinguishing device.

[0039] Specifically, the eddy current testing mechanism 7 includes a testing seat 701 fixedly connected to the surface of the welding seat 602. A second transverse electric rail 702 for transverse adjustment is fixedly connected to the testing seat 701. A third transverse slide 703 is fixedly connected to the moving part of the second transverse electric rail 702. A third transverse electric rail 704 is fixedly connected to the third transverse slide 703.

A second longitudinal slide 706 is longitudinally slidably connected to the fourth transverse slide 705. An eddy current flaw detection head 707 is fixedly connected to the bottom of the second longitudinal slide 706. A sixth longitudinal cylinder 708 is fixedly connected to the fourth transverse slide 705, and the piston rod of the sixth longitudinal cylinder 708 is fixedly connected to the second longitudinal slide 706.

[0040] In a specific embodiment of the present invention, the second transverse electric rail 702 and the third transverse electric rail 704 drive the eddy current flaw detection head 707 to scan the weld, and the sixth longitudinal cylinder 708 adjusts the detection distance to perform online non-destructive testing of weld defects, avoid fire extinguishing agent leakage, and replace manual quality inspection.

A seventh longitudinal cylinder 806 is fixedly connected to the fifth transverse slide 803, and the piston rod of the seventh longitudinal cylinder 806 is fixedly connected to the third longitudinal slide 804. Two pulleys 807 are rotatably connected to the unloading frame 801. The two pulleys 807 are connected by a transmission belt 808. The fifth transverse slide 803 is fixedly connected to the pulleys 807. A second servo motor 809 is fixedly connected to the rear side of the unloading frame 801, and the output shaft of the second servo motor 809 is fixedly connected to one of the pulleys 807.

[0042] In a specific embodiment of the present invention, the second servo motor 809 drives the pulley 807 to drive the third longitudinal slide 804, the second transport gripper 805 grabs the finished product to the unloading conveyor belt 810, the second servo motor 809 controls the unloading rhythm, seamlessly connects to the packaging process, and reduces the risk of finished product collision.

The turntable mechanism 2 is the central hub of the production line. Its turntable 202 is driven by the first servo motor 205. The limiting groove 203 carries the tank and moves cyclically along the guide groove 204. The barrel loading mechanism 3 controls the three-jaw chuck 306 to grab the tank from the support 307 through the first transverse electric rail 302 and the first longitudinal cylinder 304 and accurately place it on the turntable 202. The cover loading mechanism 4 sorts the covers through the feeding guide rail 402 and the transfer table 404 and moves them to the top of the tank by the first transporting claw 407. When the electromagnetic chuck 504 is energized, it adsorbs the top cover. The third longitudinal cylinder 517 pushes the sliding seat 503 down along the guide cylinder 502, so that the top cover fits the can opening. The adjusting protrusion 508 slides along the curved groove 510 of the guide plate 509. The spring telescopic rod 515 provides buffer pressure to avoid rigid impact damage to the can body. The second transverse cylinder 514 stabilizes the pressing process through the reinforcing plate 516 to ensure that the sealing surface is evenly stressed. The welding mechanism 6 uses laser welding technology.
