DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1-7 The present invention provides a method for welding a fireproof rolling shutter door guide rail assembly weldment, and the specific process is as follows: As an effective fireproof partition, the installation quality of the fireproof shutter door directly affects its fireproof performance. As an important component of the fireproof shutter door, the stability and firmness of the guide rail assembly are crucial. During the installation of the fireproof shutter door, a guide rail assembly welding device is required to ensure the stable connection of the guide rail. First, the guide rail assembly weldment to be welded is placed on the processing table 1, and then the welding point of the guide rail assembly weldment is moved to the middle position of the processing table 1. The top of the processing table 1 is fixedly connected with the mounting table 15, and the top of the mounting table 15 is fixedly installed with The mechanical arm 16 has a welding assembly 17 fixedly mounted on one end of the mechanical arm 16 away from the mounting platform 15, and the outer wall of the welding assembly 17 is rotatably connected to two protective covers 18, the bottom of the protective cover 18 corresponds to the top of the clamping plate 303, so that the welding part of the guide rail assembly is aligned with the lower position of the welding assembly 17. Although no vibration is generated during welding, in order to prevent vibration caused by thermal stress and deformation and to ensure the stability and accuracy of the welded parts, it is usually necessary to clamp and fix the welded parts, and then drive the motor 301 to output, so that The screw rod 302 of the output shaft is driven to rotate. Since the screw rod 302 is a bidirectional threaded rod, when the screw rod 302 rotates, the two clamping plates 303 are driven to move relative to each other, and then the side walls of the clamping plates 303 contact and squeeze the outer walls of the guide rail assembly weldment, thereby clamping the guide rail assembly weldment to prevent the workpiece from moving and deforming during the welding process. In the subsequent welding work, the welding assembly 17 is driven by the control robot arm 16 to align the welding position of the guide rail assembly weldment and move toward it. At the same time, the welding assembly 17 will The two protective covers 18 of the movable outer wall are moved. After the welding assembly 17 is moved, the ends of the two protective covers 18 that are farthest apart are engaged with the top of the clamping plate 303. Then, during the welding process, slag will continuously burst out from the welding position. The protective covers 18 can block the slag bursting upwards. At the same time, the clamping plates 303 on both sides can block the slag bursting to the sides. Then, the blocked slag will pass through the inside of the slot 2 and fall into the inside of the collecting box 4, thereby effectively cleaning the bursting slag and preventing the slag from bursting outwards. When the welding process is completed, the two clamping plates 303 are moved away from each other by driving the limiting mechanism 3, and the clamping plate 303 will drive the gear 305 to rotate through the first rack 304, and then the gear 305 will drive the second rack 306 to move in the opposite direction of the corresponding first rack 304, and a first slide groove 5 is opened through the side wall of the collection box 4, and the outer wall of the slide tube 307 is slidably connected to the inner wall of the first slide groove 5, and a second slide groove 6 is opened through the side wall of the collection box 4, and the outer wall of the slider 309 is slidably connected to the inner wall of the second slide groove 6, and the bottom of the slider 309 is slidably connected to the inside of the collection box 4, and the second rack 306 will slide along the inside of the first slide groove 5 through the slide tube 307, and the slide tube 307 will drive the slide through the connecting ring 308. The block 309 moves, and the two ends of the slider 309 slide in the second slide groove 6. At the same time, the slider 309 will slide downward along the inner wall of the connecting ring 308 during the movement. During the process, the bottom of the slider 309 will slide against the bottom of the collecting box 4, so that the slag falling into the collecting box 4 will be shoveled out and pushed to the top of the discharge port 7, and then it will pass through the inside of the discharge port 7 and fall above the push plate 11. The push plate 11 and the discharge port 7 are provided with inclined surfaces at the corresponding positions, so the slag will slide along the inclined surface of the push plate 11 to the inside of the storage box 10, so that the slag is effectively collected, and the comprehensive cleaning of the slag is achieved, and the ejected slag is prevented from adhering to the surface of the guide rail to cause damage, thereby improving the safety of the guide rail welding; When the slider 309 slides along the bottom of the inner wall of the collecting box 4, when it slides to a certain distance, the side wall of the slider 309 will contact the inclined surface of the stop block 904, and then the slider 309 will continue to squeeze the stop block 904 while sliding, and then the stop block 904 will slide toward the inside of the inner groove 8, and at the same time, it will drive the slide bar 903 to squeeze and compress the spring 905, and then the slide bar 903 will drive the other stop block 904 to move through the connecting plate 902, so that the other stop block 904 also slides toward the inside of the inner groove 8, and then the two stop blocks 904 will synchronously retract into the inside of the collecting box 4. At this time, the lower stop block 904 no longer limits the push plate 11, and then the push plate 11 will slide along the inner wall of the storage box 10 through the tension of the tension spring 14. The slag on both sides of the push plate 11 will be pushed and pushed to the corners of the storage box 10 on both sides, thereby effectively utilizing the internal space of the storage box 10 and avoiding all the slag to accumulate in one place, thereby wasting the storage space inside the storage box 10. Later, when the next welding work is carried out, the two clamping plates 303 will drive the slider 309 to slide upward during the mutual movement of each other, so that the upper stop block 904 is no longer limited, and then the two stop blocks 904 can be driven by the spring 905 to slide in the direction away from the inner groove 8, and then the handle 13 can be pushed to drive the push plate 11 to slide along the inside of the storage box 10, and then the side wall of the push plate 11 will be stuck by the stop block 904 below, thereby completing the reset, avoiding the accumulation of slag and the waste of space, and ensuring the continuous and effective use of the storage box 10.

As an important component of the fireproof shutter door, the stability and firmness of the guide rail assembly are of vital importance. During the installation of the fireproof shutter door, a guide rail assembly welding device is required to ensure the stable connection of the guide rail. First, the guide rail assembly weldment to be welded is placed on the processing table 1, and then the welding point of the guide rail assembly weldment is moved to the middle position of the processing table 1. The top of the processing table 1 is fixedly connected to the mounting table 15, and the top of the mounting table 15 is fixedly connected to the mounting table 15. A mechanical arm 16 is fixedly installed at the bottom, and a welding assembly 17 is fixedly installed at one end of the mechanical arm 16 away from the mounting platform 15, and the outer wall of the welding assembly 17 is rotatably connected to two protective covers 18, and the bottom of the protective cover 18 corresponds to the top of the clamping plate 303, so that the welding part of the guide rail assembly is aligned with the lower position of the welding assembly 17. Although no vibration is generated during welding, in order to prevent vibration caused by thermal stress and deformation and to ensure the stability and accuracy of the welded parts, it is usually necessary to clamp and fix the welded parts, and then drive the motor 301 to Output, thereby driving the screw 302 of the output shaft to rotate. Since the screw 302 is a bidirectional threaded rod, when the screw 302 rotates, it will drive the two clamping plates 303 to move relative to each other, and then the side walls of the clamping plates 303 will contact and squeeze the outer wall of the guide rail assembly weldment, thereby clamping the guide rail assembly weldment to prevent the workpiece from moving and deforming during the welding process. In the subsequent welding work, the welding assembly 17 is driven by the control robot arm 16 to align the welding position of the guide rail assembly weldment and move toward it, and at the same time, the welding assembly 1 7 will drive the two protective covers 18 of the outer wall to move. After the welding assembly 17 is moved, the ends of the two protective covers 18 that are farthest apart will be engaged with the top of the clamping plate 303. Then, during the welding process, slag will continuously burst out from the welding point. The protective cover 18 can block the slag bursting upward, and the clamping plates 303 on both sides can block the slag bursting to the side. Then the blocked slag will pass through the inside of the slot 2 and fall into the inside of the collecting box 4, thereby effectively cleaning the bursting slag and preventing the slag from bursting out.

[0025] As described above, before welding, the welding assembly 17 is directed to accurately align the welding part of the rail assembly by manipulating the robot arm 16, and slowly pushes toward it, while the welding assembly 17 pulls the two protective covers 18 installed on its outer wall to move synchronously. When the welding assembly 17 reaches the predetermined position and the two protective covers 18 are engaged at the top of the clamping plate 303, then during the welding process, the protective cover 18 effectively blocks the slag ejected upward, while the clamping plates 303 on both sides are responsible for blocking the slag ejected laterally, so that the slag falls downward and finally falls into the collection area collection box 4, achieving comprehensive cleaning of the slag, preventing the ejected slag from adhering to the surface of the rail and causing damage, thereby improving the safety of rail welding.

[0026] Embodiment 2: Based on the above embodiment, an opening and closing mechanism 9 is provided on the inner wall of the inner groove 8 .

[0027] Furthermore, the opening and closing mechanism 9 includes a rotating rod 901, and the outer wall of the rotating rod 901 is fixedly connected to a connecting plate 902, both ends of the connecting plate 902 are fixedly connected to sliding rods 903, and the outer wall of the sliding rod 903 is rotatably connected to a stop block 904, one outer wall of one sliding rod 903 is fixedly connected to a spring 905, and the end of the spring 905 away from the sliding rod 903 is fixedly connected to the inner wall of the inner groove 8, the bottom of the collection box 4 is fixedly connected to a storage box 10, and the inner wall of the storage box 10 is slidably connected to two push plates 11, the side of the two push plates 11 away from each other is fixedly connected to a connecting rod 12, and the end of the connecting rod 12 away from the push plate 11 is fixedly connected to a handle 13, the side wall of the push plate 11 is fixedly connected to a tension spring 14, and the end of the tension spring 14 away from the push plate 11 is fixedly connected to the side wall of the storage box 10.

[0028] More specifically, when the welding process is completed, the two clamping plates 303 are moved away from each other by driving the limiting mechanism 3, and at the same time, the clamping plate 303 will drive the gear 305 to rotate through the first rack 304, and then the gear 305 will drive the second rack 306 to move in the opposite direction of the corresponding first rack 304, and a first slide groove 5 is opened through the side wall of the collection box 4, and the outer wall of the slide tube 307 is slidably connected to the inner wall of the first slide groove 5, and a second slide groove 6 is opened through the side wall of the collection box 4, and the outer wall of the slide block 309 is slidably connected to the inner wall of the second slide groove 6, and the bottom of the slide block 309 is slidably connected to the inside of the collection box 4, and at the same time, the second rack 306 will pass through the slide tube 307 along the first slide The slider 309 will slide inside the groove 5, and the slide tube 307 will drive the slider 309 to move through the connecting ring 308. Since the two ends of the slider 309 slide in the second slide groove 6, the slider 309 will slide downward along the inner wall of the connecting ring 308 during the movement. During the process, the bottom of the slider 309 will slide against the bottom of the collecting box 4, thereby scraping off the slag that falls into the collecting box 4 and pushing it to the top of the discharge port 7. Then it will pass through the inside of the discharge port 7 and fall above the push plate 11. The push plate 11 and the corresponding position of the discharge port 7 are provided with inclined surfaces, so the slag will slide along the inclined surface of the push plate 11 to the inside of the storage box 10, thereby effectively collecting the slag.

[0029] In the process of collecting slag, when the slider 309 slides along the bottom of the inner wall of the collection box 4, when it slides to a certain distance, the side wall of the slider 309 will contact the inclined surface of the stop block 904, and then the slider 309 will continue to squeeze the stop block 904 while sliding, and then the stop block 904 will slide toward the inside of the inner groove 8, and at the same time, it will drive the slide bar 903 to squeeze and compress the spring 905, and then the slide bar 903 will drive the other stop block 904 to move through the connecting plate 902, so that the other stop block 904 also slides toward the inside of the inner groove 8, and then the two stop blocks 904 will synchronously retract into the inside of the collection box 4. At this time, the lower stop block 904 no longer limits the push plate 11, and then the push plate 11 will be pulled along by the tension of the tension spring 14 The slag on both sides of the push plate 11 will be pushed along the inner wall of the material storage box 10, and the slag will be pushed to the corners on both sides of the material storage box 10, thereby effectively utilizing the internal space of the material storage box 10 and avoiding all the slag from accumulating in one place, thereby wasting the storage space inside the material storage box 10. Later, when the next welding work is carried out, the two clamping plates 303 will drive the slider 309 to slide upward during the mutual movement of the two clamping plates 303, so that the upper stop block 904 is no longer limited, and then the two stop blocks 904 can be driven by the spring 905 to slide in the direction away from the inner groove 8, and then the handle 13 can be pushed to drive the push plate 11 to slide along the inside of the material storage box 10, and then the side wall of the push plate 11 will be stuck by the stop block 904 below, thereby completing the reset.

[0030] As described above, when the welding process is completed, the two clamping plates 303 are moved away from each other through the driving device. This movement drives the gear 305 to rotate by connecting the first rack 304. At the same time, the slide tube 307 slides along the first channel slot 5 opened on the side wall of the structural collection box 4, so that the two ends of the slider 309 slide in the second slot 6. At the same time, the bottom of the slider 309 fits the bottom of the structural collection box 4, and the slag falling into the collection box 4 is shoveled out and pushed to the discharge port 7 to fall into the storage box 10, thereby achieving effective collection of the slag. Moreover, through the synchronous retraction of the two stops 904 and the sliding of the push plate 11, the internal space of the storage box 10 is cleverly utilized, avoiding the accumulation of slag and the waste of space, thereby ensuring the continuous and effective use of the storage box 10.
