In pipeline systems, explosion-proof disk welding technology is a crucial process that is directly related to the safety and stability of the system.

[0003] With the continuous advancement of welding technology, explosion-proof disk welding technology has also been significantly developed. At present, commonly used welding methods include manual welding, automatic welding and laser welding. Manual welding is suitable for some small and simple devices, which requires operators to perform manually and has certain requirements on the skills and experience of operators; automatic welding is an automated welding method with high efficiency and good consistency. It is suitable for the production line of small and medium-sized explosion-proof disks. Automatic welding requires the use of special equipment and robots, and requires pre-programming and debugging; laser welding is a high-precision and high-efficiency welding method suitable for high-end explosion-proof disk products. Laser welding can accurately control the welding position and parameters, avoid secondary pollution, and improve welding quality and safety.

[0004] Currently, during laser welding, it is necessary to drive the explosion-proof plate to rotate through a rotating base, and at the same time use a laser welder to weld the gaps around the explosion-proof plate and the pipe mounting plate. During welding, in order to prevent the position of the explosion-proof plate from shifting, the explosion-proof plate and the pipe mounting plate need to be clamped to improve the welding quality.

Start the suction pump inside the suction head to absorb gas, the gas will enter the connecting pipe, the gas in the connecting pipe will enter the connecting hose, and the gas in the connecting hose will enter the buffer bin; S2. Use external force to lift the rubber clamping plate, which will push the reset spring to generate elastic force, and then place the pipe mounting plate on the placement plate, and place the explosion-proof plate on the pipe mounting plate. After placement, release the external force restriction, and the reset spring will push the rubber clamping plate to squeeze the explosion-proof plate, so as to facilitate stable positioning and placement of the explosion-proof plate; S3. When the explosion-proof disk is firmly placed, start the servo motor, which will drive the screw to rotate. The rotation of the screw will facilitate the moving part to move in a directional manner using the guide rod. When the moving part moves to the point where the hollow tube is located above the fixed disk, the fixed disk blocks the air outlet end of the hollow tube. As the suction head continues to inhale, the air pressure in the buffer bin will push the connecting plate down. The descent of the connecting plate will drive the air outlet of the pressure relief valve to move out of the buffer bin, reducing the pressure in the buffer bin. When the hollow tube moves to the position of the air inlet, it will stay for a certain period of time. Under the action of the air pressure, the hollow tube will open the self-locking component and inject gas into the hollow plate. The gas will expand the rubber clamping plate, thereby further clamping the explosion-proof disk. When the rubber clamping plate expands to the target size, the air pressure in the buffer bin drops, the hollow tube retracts, and the self-locking component automatically closes.

After the spot welding is completed, the servo motor is used to drive the moving part to move continuously. When the moving part moves to the fixed frame position, the fixed rod will open the moving block, and the suction head will use the extension pipe to absorb the gas inside the rubber clamping plate; S6. When the gas inside the rubber clamping plate is exhausted, the servo motor uses the screw rod to drive the moving part away from the fixed frame, and at the same time starts the adjustment mechanism, laser welder and rotating base. The laser welder welds the gaps around the explosion-proof plate and the pipeline installation plate, and the welding is firm and stable. S7. After the industrial large-scale explosion-proof plates are welded, the suction head will absorb a large amount of hot air generated by the laser welder into the buffer chamber, which will reduce the large amount of high temperature accumulated in the welding place of the laser welder and prevent defects such as pores, cracks, and unfusion in the weld. At the same time, the heat in the buffer chamber is convenient for the preliminary preheating of the explosion-proof plates to improve the welding quality.

[0017] Compared with the prior art, the invention has the following beneficial effects: when the explosion-proof disc production welding device welds the explosion-proof disc to the pipeline mounting plate, it is convenient to clamp and fix the explosion-proof disc and the pipeline mounting plate, thereby improving the welding quality. The specific contents are as follows; 1. The explosion-proof disk production welding device, when in use, utilizes telescopic rods, reset springs and rubber clamping plates to facilitate stable positioning and placement of the explosion-proof disk. When the explosion-proof disk is firmly placed, the conveying mechanism is utilized to drive the movable part to move in a directional manner. When the movable part moves to the point where the hollow tube is located above the fixed disk, the fixed disk blocks the air outlet end of the hollow tube. As the suction head continues to inhale air, the air pressure in the buffer bin will push the connecting plate down. The descent of the connecting plate will drive the air outlet of the pressure relief valve to move out of the buffer bin, thereby reducing the pressure in the buffer bin. When the hollow tube moves to the position of the air inlet and stays there for a certain period of time, under the action of the air pressure, the hollow tube will open the self-locking component and inject gas into the hollow plate. The gas will cause the rubber clamping plate to expand, thereby further clamping the explosion-proof disk. When the rubber After the rubber clamping plate expands to the target size, the air pressure in the buffer bin drops, the hollow tube retracts, the self-locking component automatically closes, and the conveying mechanism continues to be started. When the moving part moves away from the buffer bin and does not reach the fixed frame position, the laser welder and the adjustment mechanism are used to spot weld the connection gap between the explosion-proof disk and the pipeline connecting plate. After the spot welding is completed, when the moving part moves to the fixed frame position, the fixed rod will open the moving block, and the suction head will use the extension pipe to absorb the gas inside the rubber clamping plate. When the gas inside the rubber clamping plate is discharged, the servo motor uses the screw rod to drive the moving part away from the fixed frame, and starts the adjustment mechanism, laser welder and rotating base at the same time. The laser welder will weld the gaps around the explosion-proof disk and the pipeline mounting plate. The welding is firm and stable.

[0018] 2. When using the explosion-proof disk production welding device, start the suction pump inside the suction head to absorb gas, the gas will enter the connecting pipe, the gas in the connecting pipe will enter the connecting hose, and the gas in the connecting hose will enter the buffer bin. After the industrial large-scale explosion-proof disks are welded, the suction head will absorb a large amount of hot air generated by the laser welder into the buffer bin, which will reduce the large amount of high temperature accumulated at the welding point of the laser welder and prevent defects such as pores, cracks, and unfusion from occurring in the weld. At the same time, the heat in the buffer bin is convenient for preliminary preheating of the explosion-proof disk and improves the welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

When the rubber clamping plate 642 expands to the target size, the gas pressure in the buffer chamber 40 drops, the hollow tube 42 retracts, and the self-locking component 8 automatically closes.

After the spot welding is completed, the servo motor 50 is used to drive the moving member 60 to continue to move. When the moving member 60 moves to the position of the fixed frame 70, the fixed rod 71 will open the moving block 646, and the suction head 30 will use the extension pipe 72 to absorb the gas inside the rubber clamping plate 642; S6. After the gas inside the rubber clamping plate 642 is exhausted, the servo motor 50 drives the moving part 60 away from the fixed frame 70 by means of the screw rod 51, and simultaneously starts the adjustment mechanism 2, the laser welder 11 and the rotating base 62.

After the industrialized large-scale explosion-proof plates are welded, the suction head 30 will absorb a large amount of hot air generated by the laser welder 11 into the buffer chamber 40, which will reduce the large amount of high temperature accumulated at the welding point of the laser welder 11 and prevent defects such as pores, cracks, and unfusion from occurring in the weld. At the same time, the heat in the buffer chamber 40 is convenient for preliminary preheating of the explosion-proof plates to improve the welding quality.

10. A method for using a welding device for producing explosion-proof disks according to claims 1-9, characterized in that: The specific steps are: S1, starting the suction pump inside the suction head (30) to suck gas, the gas will enter the connecting pipe (31), the gas in the connecting pipe (31) will enter the connecting hose (32), and the gas in the connecting hose (32) will enter the buffer chamber (40); S2. Use external force to lift the rubber clamping plate (642), the rubber clamping plate (642) will push the reset spring (643) to generate elastic force, then place the pipeline installation plate on the placement plate (63), and place the explosion-proof plate on the pipeline installation plate. After placement, release the external force restriction, the reset spring (643) will push the rubber clamping plate (642) to squeeze the explosion-proof plate, so as to facilitate stable positioning and placement of the explosion-proof plate; S3. After the explosion-proof disk is firmly placed, the servo motor (50) is started. The servo motor (50) drives the screw rod (51) to rotate. The rotation of the screw rod (51) facilitates the movable member (60) to move in a directional manner using the guide rod (54). When the movable member (60) moves to the point where the hollow tube (42) is located above the fixed plate (640), the fixed plate (640) blocks the air outlet end of the hollow tube (42). As the air suction head (30) continues to suck air, the air pressure in the buffer chamber (40) pushes the connecting plate (43) down. The downward movement of the connecting plate (43) drives the pressure relief valve ( The gas outlet of the hollow tube (44) moves out of the buffer chamber (40), reducing the pressure in the buffer chamber (40). When the hollow tube (42) moves to the position of the gas inlet (644), it stays for a certain period of time. Under the action of the gas pressure, the hollow tube (42) will open the self-locking component (8) and inject gas into the hollow plate (64). The gas will cause the rubber clamping plate (642) to expand, thereby further clamping the explosion-proof plate. When the rubber clamping plate (642) expands to the target size, the gas pressure in the buffer chamber (40) decreases, the hollow tube (42) retracts, and the self-locking component (8) automatically closes. S4, using the servo motor (50) to drive the moving part (60) to move continuously, and when the moving part (60) moves to a position away from the buffer bin (40) but not reaching the fixed frame (70), using the laser welder (11) and the adjustment mechanism (2) to spot weld the connection gap between the explosion-proof disk and the pipeline connection plate (43); S5. After the spot welding is completed, the servo motor (50) is used to drive the moving member (60) to continue to move. When the moving member (60) moves to the position of the fixed frame (70), the fixed rod (71) will open the moving block (646), and at the same time, the suction head (30) will use the extension pipe (72) to absorb the gas inside the rubber clamping plate (642); S6. When the gas inside the rubber clamping plate (642) is exhausted, the servo motor (50) drives the moving part (60) away from the fixed frame (70) by means of the screw rod (51), and simultaneously starts the adjustment mechanism (2), the laser welder (11) and the rotating base (62). The laser welder (11) welds the gaps around the explosion-proof plate and the pipe mounting plate, and the welding is firm and stable. S7. After industrial large-scale welding of explosion-proof disks, the suction head (30) will absorb a large amount of hot air generated by the laser welder (11) into the buffer chamber (40), which will reduce the large amount of high temperature accumulated at the welding point of the laser welder (11) and prevent defects such as pores, cracks, and lack of fusion from occurring in the weld. At the same time, the heat in the buffer chamber (40) facilitates the preliminary preheating of the explosion-proof disk and improves the welding quality.
