[0015] A production line control method for an automated flange pipeline welding production line comprises the following steps: 1. Place multiple pipes that need to be welded with flanges on the unloading rack. Since the unloading rack has a slope, the pipes will automatically roll slowly and be arranged above the baffle on the unloading rack after unloading. When the equipment is started, the turning mechanisms on both sides will move at the same time, turning the pipe in contact with the baffle down to the waiting area, waiting for the next operation; 2. After the pipeline is turned over to the waiting area, the alignment mechanisms on the left and right sides are activated to align the pipeline in the middle to ensure that the initial position of the pipeline is fixed and in the middle, in preparation for the subsequent flange docking, and the flanges on both sides are placed in the clamping claw structure and clamped; 3. In the initial state, the movable rods of the third electric cylinder and the fourth electric cylinder are in a retracted state, the translation slide is on the side close to the material unloading rack, and the pipe supports on both sides are in a falling state; when the pipeline needs to be moved, the movable rods of the fourth electric cylinders on both sides are controlled to lift up, and the pipe supports on the side close to the material unloading rack hold up the pipeline in the waiting area (during the first operation, the top of the pipe support on the side away from the material unloading rack is empty, because the top of the pipe support on this side corresponds to the pipe rotating mechanism, and there is no pipe above it for the first time; if it is not the first time, the finished product welded on the pipe rotating mechanism will be held up), and then the translation slide is driven by the third electric cylinder to move to the side of the material receiving rack. After it is in place, the pipe support on the side close to the material unloading rack faces the clamping claw structure, and the pipe support on the side close to the material receiving rack faces the material receiving rack; Fourth, the movable rod of the fourth electric cylinder is kept in the jacking state, and the lateral sliding structures on both sides are controlled to approach each other, so that the clamping claw structure drives the flange to dock into the pipe above the pipe rotating mechanism; then the robot welding module is controlled to spot weld the flange, spot weld the flange and the pipe together, and then the movable rod of the fourth electric cylinder is controlled to fall, and the semi-finished pipe on the pipe rotating mechanism will fall onto the pipe rotating mechanism, and the finished product (if there is material) on the pipe bracket corresponding to the receiving rack will fall onto the receiving rack, so as to realize automatic material receiving; 5. After falling into place, the third electric cylinder controls the translation slide to return to the initial position and wait for the next material transfer; 6. When the semi-finished pipe is placed on the pipe rotating mechanism, the control power mechanism drives the rotating roller to rotate through the transmission shaft, and the rotating roller drives the semi-finished pipe above it to rotate. During the rotation, the robot welding module fully welds the flange and the pipe connection. After completion, the pipe rotating mechanism stops rotating, and the robot welding module returns to the initial position, completing a pipe flange welding; 7. The second pipeline translation starts, and the action process of the pipeline translation mechanism is repeated, namely: the fourth electric cylinder movable rod body on both sides is controlled to lift up, the pipeline support close to the side of the material placing rack holds up the pipeline in the waiting area, and the pipeline support close to the side of the material receiving rack holds up the finished pipeline that has been welded on the pipeline rotating mechanism, and then the third electric cylinder is used to drive the translation slide to move to the side of the material receiving rack. After it is in place, the lateral sliding structures on both sides are controlled to approach each other, so that the clamping claw structure drives the flange to dock into the pipeline above the pipeline rotating mechanism; then the robot welding module is controlled to spot weld the flange, spot weld the flange and the pipeline together, and then the fourth electric cylinder movable rod body is controlled to fall, the semi-finished pipeline on the pipeline rotating mechanism will fall onto the pipeline rotating mechanism, and the finished pipeline on the pipeline support corresponding to the material receiving rack will fall onto the material receiving rack, so as to realize automatic material receiving; after falling into place, the third electric cylinder is used to control the translation slide to return to the initial position, waiting for the next material shifting; 8. Repeat step 7 and continue pipe welding.

[0016] The above technical solution has the following beneficial effects: The automated flange and pipe welding production line consists of a complete automated production line consisting of a feeding module, an alignment module, a welding support module, a robot welding module, a receiving module and an electrical control module. It only requires manual placement of the flange and no longer requires manual participation. It can fully mechanize the transfer, welding and continuous feeding of flange pipes, automatically weld the flanges and pipes and arrange them neatly. The production line can accurately position the pipes and improve the accuracy of flange welding. The overall automated production line can greatly improve the degree of automation of flange and pipe welding, improve production efficiency, reduce manual labor intensity, and thus reduce the risk factor, meet the production needs of enterprises, create good economic and social benefits for customers, and is more conducive to the use of flange and pipe welding.

The baffle 10 can limit the pipes placed on the unloading rack 1 to prevent all the pipes from piling up in the waiting area and affecting the operation of the pipe translation mechanism 5. There are two unloading racks 1 and two turning mechanisms 2, and the two unloading racks 1 are arranged parallel to each other. The two unloading racks 1 are arranged on the same side of the pipe rotating mechanism 7 and are symmetrically arranged with the vertical midline of the pipe rotating mechanism 7 as the symmetry axis. The two unloading racks 1 are supported at both ends of the pipe to ensure that the pipe is placed stably.

[0021] The alignment module is composed of a support frame 3 and an alignment mechanism 4, which is arranged on the upper surface of the support frame 3. The alignment mechanism 4 includes a second electric cylinder 401 and an alignment push plate 402. The fixed cylinder body part of the second electric cylinder 401 is fixedly installed on the upper surface of the support frame 3. The alignment push plate 402 is fixedly connected to the end of the movable rod body of the second electric cylinder 401 and can abut against the end of the pipe on the unloading rack 1 that is closest to the pipe rotating mechanism 7. Alignment modules are arranged on both sides of the unloading rack 1 and the alignment push plates 402 in the two alignment modules can abut against the two ends of the pipe respectively. When the turning mechanism 2 turns the pipe to the waiting area, the movable rod bodies of the second electric cylinder 401 on both sides are controlled to extend at the same time, so that the alignment push plates 402 on both sides can be pushed to the two ends of the pipe and push the pipe to the middle part, so that it is aligned with the middle part of the pipe rotating mechanism 7, which can ensure that after the pipe translation mechanism 5 moves the pipe to the top of the pipe rotating mechanism 7, the flange installation mechanisms 6 on both sides can accurately correspond the flanges 604 to the two sides of the pipe to prevent the flanges 604 from being installed in place.

[0022] It also includes a welding support module for flange welding on both sides of the pipeline and a robot welding module for welding. The welding support module is composed of a pipeline translation mechanism 5, a flange mounting mechanism 6 and a pipeline rotation mechanism 7. Both sides of the pipeline rotation mechanism 7 are provided with a pipeline translation mechanism 5, a flange mounting mechanism 6 and a robot welding module. The bottoms of the pipeline translation mechanism 5, the flange mounting mechanism 6 and the pipeline rotation mechanism 7 are fixedly installed with the same base. There are two robot welding modules and the two robot welding modules are respectively arranged on the same side of the two flange mounting mechanisms 6. The robot welding module is a welding robot in the prior art and is a relatively mature automated welding technology, so it will not be elaborated on here. The robot welding module can weld the flange 604 to the end of the pipeline.

[0023] The pipeline translation mechanism 5 includes a translation frame 501, a slide rail 502, a translation slide 503 and a third electric cylinder 504. The translation frame 501 is fixedly installed above the base and the slide rail 502 is fixedly connected to the side of the translation frame 501. The translation slide 503 is slidably connected to the outside of the slide rail 502. The cylinder body of the third electric cylinder 504 is horizontally fixedly installed in the middle of the side of the translation frame 501 and the end of the movable rod body is fixedly connected to the translation slide 503. The movable rod body of the third electric cylinder 504 extends outward or retracts inward, which can drive the translation slide 503 to move horizontally, thereby driving the top pipeline to translate horizontally.

[0024] The pipeline translation mechanism 5 also includes a fourth electric cylinder 505 and a pipeline support 506. The cylinder body of the fourth electric cylinder 505 is vertically fixedly installed on the side of the translation slide 503 and the pipeline support 506 is fixedly installed on the top of the movable rod body of the fourth electric cylinder 505. The fourth electric cylinder 505 is fixedly installed on both ends of the side of the translation slide 503. The pipeline translation mechanism 5 on both sides of the pipeline rotation mechanism 7 is symmetrically arranged. The movable rod body parts of the fourth electric cylinders 505 on both sides are synchronously extended and retracted, which can lift up or put down the pipeline.

[0025] The flange mounting mechanism 6 includes a frame 601, a transverse sliding structure 602, a clamping structure 603 and a flange 604. The frame 601 is fixedly mounted on the upper surface of the base and the flange 604 is stacked on the side of the upper surface of the frame 601 away from the pipeline rotating mechanism 7. Multiple flanges 604 are stacked on each other. When they are needed, the top flange 604 is taken and placed in the clamping structure 603. The transverse sliding structure 602 is set on the upper surface of the frame 601 and the clamping structure 603 is set on the top of the transverse sliding structure 602. The sliding structure 602 and the clamping structure 603 are existing well-known technologies, so they will not be elaborated on here. The lateral sliding structure 602 can drive the clamping structure 603 to move horizontally. The two flange mounting mechanisms 6 are symmetrically arranged with the vertical center line of the pipeline rotating mechanism 7 as the symmetry axis, and the axis center of the two clamping structures 603 can correspond horizontally to the axis center of the pipeline placed on the pipeline rotating mechanism 7. The clamping structure 603 can clamp the flange 604, so that the flange 604 can be matched to the two ends of the pipeline, which is convenient for precise welding.

[0026] The pipeline rotating mechanism 7 includes a rotating frame 701, a power mechanism 702, a transmission shaft 703 and a rotating roller 704. The rotating frame 701 is fixedly installed in the middle of the base and the power mechanism 702 is arranged in the middle of the rotating frame 701. The transmission shaft 703 is transmission-connected to the output end of the power mechanism 702 and there are two of them. Both ends of the two transmission shafts 703 are rotationally connected to the top of the rotating frame 701 through bearings and rotating rollers 704 are fixedly installed at both ends and the middle. The two transmission shafts 703 are arranged parallel to each other and are in the same horizontal plane. The power mechanism 702 drives the two transmission shafts 703 to rotate synchronously, which can drive the semi-finished pipeline placed above to rotate, thereby facilitating the robot welding module to weld the flanges 604 at both ends as a whole, and all the contact parts of the flanges 604 and the pipeline are tightly welded together.

[0027] It also includes a material receiving module for placing flange pipes after welding and an electrical control module for controlling the entire production line. The material receiving module is specifically a material receiving rack 8, which is arranged on the side of the pipe rotating mechanism 7 away from the material discharging rack 1. The structure of the material receiving rack 8 is the same as that of the material discharging rack 1 and corresponds to the position of the material discharging rack 1. There are two material receiving racks 8 and the two material receiving racks 8 correspond to the two material discharging racks 1 respectively. The higher side of the two material receiving racks 8 is close to the pipe rotating mechanism 7. The material receiving rack 8 has the same structure as the material discharging rack 1. There is no turning mechanism inside the material receiving rack 8. After the finished pipe is placed on the material receiving rack 8, it will slowly roll to the tail and be placed side by side and flush; the electrical control module is specifically an electrical control box 9, which is electrically connected to the material discharging module, the alignment module, the welding support module and the robot welding module in the form of electrical signals, and is internally provided with an intelligent control unit that can control the various modules to cooperate with each other to form an automated production line.

[0028] A production line control method for an automated flange pipe welding production line, the specific operation steps are as follows: 1. Place multiple pipes that need to be welded with flanges on the unloading rack 1. Since the unloading rack 1 has a slope, the pipes will automatically roll slowly after unloading and be arranged above the baffle 10 on the unloading rack 1. When the equipment is started, the turning mechanisms 2 on both sides will move at the same time, turning a pipe in contact with the baffle 10 downward to the waiting area, waiting for the next operation; 2. After the pipeline is turned over to the waiting area, the alignment mechanisms 4 on the left and right sides are activated to align the pipeline in the middle, ensuring that the initial position of the pipeline is fixed and in the middle, preparing for the subsequent flange docking, and placing the flanges 604 on both sides into the clamping claw structure 603 and clamping it; 3.

After it is in place, the pipe support 506 on the side close to the material discharging rack 1 faces the clamping claw structure 603, and the pipe support 506 on the side close to the material receiving rack 8 faces the material receiving rack 8; Fourth, the movable rod of the fourth electric cylinder 505 is kept in the jacking state, and the lateral sliding structures 602 on both sides are controlled to approach each other, so that the clamping claw structure 603 drives the flange 604 to dock into the pipeline above the pipeline rotating mechanism 7; then the robot welding module is controlled to spot weld the flange 604, and the flange 604 and the pipeline are spot welded together, and then the movable rod of the fourth electric cylinder 505 is controlled to fall, and the semi-finished pipeline on the pipeline rotating mechanism 7 will fall onto the pipeline rotating mechanism 7, and the finished product (if there is material) on the pipeline support 506 corresponding to the material receiving rack 8 will fall onto the material receiving rack 8, so as to realize automatic material receiving; 5. After falling into place, the third electric cylinder 504 controls the translation slide 503 to return to the initial position and wait for the next material transfer; 6. After the semi-finished pipe is placed on the pipe rotating mechanism 7, the power mechanism 702 is controlled to rotate the rotating roller 704 through the transmission shaft 703, and the rotating roller 704 drives the semi-finished pipe above it to rotate. During the rotation, the robot welding module fully welds the flange 604 and the pipe connection. After completion, the pipe rotating mechanism 7 stops rotating, and the robot welding module returns to the initial position, completing a pipe flange welding; 7. The second pipeline translation begins, and the action process of the pipeline translation mechanism 5 is repeated, that is: the movable rods of the fourth electric cylinders 505 on both sides are controlled to lift up, and the pipeline support 506 on the side close to the material placing rack 1 holds up the pipeline in the waiting area, and the pipeline support 506 on the side close to the material receiving rack 8 holds up the finished pipeline that has been welded on the pipeline rotating mechanism 7, and then the translation slide 503 is driven by the third electric cylinder 504 to move to the side of the material receiving rack 8. After it is in place, the lateral sliding structures 602 on both sides are controlled to approach each other, so that the clamping claw structure 603 drives the flange 6 04 is docked into the pipeline above the pipeline rotating mechanism 7; then the robot welding module is controlled to spot weld the flange 604, and the flange 604 is spot welded to the pipeline, and then the movable rod of the fourth electric cylinder 505 is controlled to fall, and the semi-finished pipeline on the pipeline rotating mechanism 7 will fall onto the pipeline rotating mechanism 7, and the finished pipeline on the pipeline support 506 corresponding to the material receiving rack 8 will fall onto the material receiving rack 8, so as to realize automatic material receiving; after falling into place, the translation slide 503 is controlled by the third electric cylinder 504 to return to the initial position and wait for the next material transfer; 8.

10. A production line control method implemented by an automated flange pipe welding production line according to any one of claims 1 to 9, characterized in that: The following steps are involved:

1. Place multiple pipes that need to be welded with flanges on the unloading rack (1). Since the unloading rack (1) has a slope, the pipes will automatically roll slowly and be arranged on the unloading rack (1) after unloading. When the equipment is started, the turning mechanisms (2) on both sides will move simultaneously to turn the bottom pipe downward to the waiting area to wait for the next operation; 2. After the pipeline is turned over to the waiting area, the alignment mechanisms (4) on the left and right sides are started to align the pipeline in the middle, ensuring that the initial position of the pipeline is fixed and in the middle, preparing for the subsequent flange docking, and the flange installation mechanism (6) is prepared to ensure that the flanges on both sides can be installed on both sides of the pipeline under the action of the flange installation mechanism (6); 3. In the initial state, the pipeline translation mechanism (5) is on the side close to the material placing rack (1) and is in a retracted state as a whole; when the pipeline needs to be moved, the pipeline translation mechanism (5) is controlled to lift the pipeline in the material waiting area so that it drives the pipeline to move to the side of the material receiving rack (8); 4. After the pipe is in place, the pipe translation mechanism (5) is kept fixed, and the flange installation mechanisms (6) on both sides are operated to connect the flanges on both sides into the pipe above the pipe rotation mechanism (7). Then, the robot welding module is controlled to spot weld the connection parts to spot weld the flange and the pipe together. Then, the pipe translation mechanism (5) is controlled to drop the spot-welded semi-finished pipe onto the pipe rotation mechanism (7). After the semi-finished pipe is dropped into place, the pipe translation mechanism (5) is returned to the initial position to wait for the next material transfer.

5. After the semi-finished pipe is placed on the pipe rotating mechanism (7), the pipe rotating mechanism (7) is controlled to move so as to drive the semi-finished pipe above it to rotate. During the rotation, the robot welding module fully welds the connection between the flange and the pipe. After completion, the pipe rotating mechanism (7) stops rotating, and the robot welding module returns to the initial position, completing the welding of a pipe flange; Sixth, the second pipeline translation begins, the preparation work of the flange installation mechanism (6) is completed again, and the action process of the pipeline translation mechanism (5) is repeated, that is: the side of the pipeline translation mechanism (5) close to the material placing rack (1) is controlled to lift the pipeline in the waiting area and move it to the side of the material receiving rack (8); the side of the pipeline translation mechanism (5) close to the material receiving rack (8) lifts the finished pipeline that has been welded on the pipeline rotating mechanism (7) and moves it to the side of the material receiving rack (8); after it is in place, the flange installation mechanisms (6) on both sides are controlled to dock the flange into the pipeline above the pipeline rotating mechanism (7); then the robot welding module is controlled to perform spot welding, and then the pipeline translation mechanism (5) is controlled to fall, and the corresponding semi-finished pipeline on the pipeline rotating mechanism (7) will fall onto the pipeline rotating mechanism (7), and the corresponding finished pipeline on the material receiving rack (8) will fall onto the material receiving rack (8), so as to realize automatic material receiving; after falling into place, the pipeline translation mechanism (5) is controlled to return to the initial position and wait for the next material movement; 7. Repeat step 6 and continue pipe welding.
