Description

Technical Field

[0001] The present invention belongs to the technical field of welding robots, and specifically relates to a mobile welding robot. Background Art

[0002] Welding, also known as fusion welding, is a method of joining metals or other thermoplastic materials by heating, high temperature or high pressure. The energy sources used in welding include gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves, etc., and are widely used in various machining or engineering construction.

[0003] In the prior art, for a large number of repetitive welding operations, welding robots are mostly used for batch welding. The welding robots in the prior art can be generally divided into fixed types and mobile types. Among them, the fixed type mostly drives a welding torch through a robotic arm for welding, while the mobile type generally installs a track on the surface of the workpiece to be welded, and then the welding robot welds the surface of the workpiece along the track.

[0004] In the prior art, the welding robot needs to weld the workpiece along the track, and it is necessary to install a guide rail on the surface of the workpiece first. However, due to the different lengths of the workpieces, the required lengths of the guide rails are also different, and workers need to continuously add and remove the guide rails, which increases the work process and affects the welding efficiency.

[0005] Therefore, the present invention provides a mobile welding robot. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A mobile welding robot according to the present invention includes three guide plates; the three guide plates are arranged end to end in sequence; a pair of electromagnet blocks are fixedly connected to one side surface of the guide plate; a moving seat is slidably connected to the side surface of the guide plate far from the electromagnet block; a driving component is installed on the surface of the moving seat; the driving component is used to drive the moving seat to move on the surface of the guide plate; a mounting seat is fixedly connected to the side surface of the moving seat far from the guide plate; a chute is opened on the side surface of the mounting seat far from the moving seat; a connecting component is installed in the chute; a welding torch is installed at the end of the connecting component; the connecting component is used to connect the welding torch and the mounting seat; a support seat is installed on the side surface of the mounting seat far from the moving seat; a transfer component is installed on the side surface of the support seat far from the mounting seat; the transfer component is used to transfer the guide plate on one side of the moving seat to the other side of the moving seat, and a microcomputer is arranged inside the support seat, and this microcomputer is used to control each execution component in the present invention; during work, when the user needs to weld multiple workpieces on the same base, the embodiment of the present invention can be used. First, the user needs to turn on the electromagnet blocks, adsorb the three guide plates connected end to end in sequence on the surface of the workpiece, and align the welding torch with the joint between the base and the workpiece. Then, the driving component drives the moving seat, the mounting seat, the support seat and the welding torch to move along the guide plate, so that the welding torch smoothly passes through the joint, thereby completing the welding operation between the multiple workpieces and the base. When the moving seat moves to the middle position of the middle guide plate among the three guide plates, the transfer component on the surface of the support seat will transfer the guide plate far from the moving seat travel direction to the end close to the travel direction, so that the moving seat can continue to move forward along the guide plate, thereby avoiding the user from frequently disassembling and installing the guide plate, reducing the work process, improving the welding efficiency. At the same time, automatically extending the guide plate can also enable the embodiment of the present invention to cope with workpieces of different lengths, expanding the application range of the embodiment of the present invention.

[0008] Preferably, the transfer component includes a rotating column; the rotating column is rotatably connected to the support base, and the rotating column is driven by a servo motor inside the support base; a connecting plate is mounted on the surface of the rotating column; a connecting column is fixedly connected to one end of the connecting plate away from the rotating column; an electromagnet column is mounted at one end of the connecting column close to the guide plate; a metal sheet is fixedly connected to the surface of the guide plate at a position corresponding to the electromagnet column, and the metal sheet is made of a magnetizable metal material; a contact piece one is fixedly connected to the side surface of the electromagnet column close to the guide plate; a contact piece two is fixedly connected to the surface of the guide plate at a position corresponding to the contact piece one; the microcomputer can control the energization and de-energization of the electromagnet block through the contact of the contact piece one and the contact piece two; during operation, when it is necessary to transfer the guide plate, first, the moving seat, the mounting seat, and the support base will move to the middle guide plate, then the servo motor drives the rotating column to rotate, and then the rotating column drives the connecting plate to rotate, so that the connecting plate rotates to the side away from the traveling direction. Subsequently, the electromagnet column at the end of the connecting column will adsorb the metal sheet on the surface of the guide plate, and make the contact piece one on the surface of the electromagnet column contact the contact piece two on the surface of the guide plate, thereby completing the connection of the contact piece one and the contact piece two. The microcomputer at the support base controls the de-energization of the electromagnet block, so that the guide plate is separated from the adsorption on the surface of the workpiece. Subsequently, the rotating column drives the connecting plate and the connecting column to rotate 90 degrees, and then the moving seat drives the mounting seat, the support base, the rotating column, the connecting plate, the connecting column, the electromagnet column, and the guide plate adsorbed by the electromagnet column to move together. When moving to the middle of the last guide plate in the traveling direction, the rotating column drives the connecting plate, the connecting column, the electromagnet column, and the guide plate adsorbed by the electromagnet to rotate to the traveling direction of the moving seat. Subsequently, the microcomputer controls the activation of the electromagnet block, so that the guide plate is adsorbed to the surface of the workpiece again, and the three guide plates are connected end to end in sequence again. Then the electromagnet column is de-energized to release the adsorption on the metal sheet and the guide plate. By continuously cycling the above process, the guide plate can be continuously extended in the traveling direction of the moving seat, so that the moving seat moving on the guide plate can drive the welding torch to continuously weld the seam between the workpiece and the base. The microcomputer controls the de-energization of the electromagnet through the contact piece one and the contact piece two, so that when transferring the guide plate, the electromagnet column, the connecting column, the connecting plate, and the rotating column can be more relaxed and no longer need to resist the adsorption force between the electromagnet block and the workpiece, thereby reducing the pressure on the servo motor and prolonging its service life.

[0009] Preferably, a slide bar is slidably connected to one end of the rotating column away from the mounting seat; the slide bar is fixedly connected to the connecting plate; a support plate is fixedly connected to one side of the surface of the rotating column close to the support seat, and the support plate is slidably connected to the surface of the support seat; an electric push rod is fixedly connected to the surface of the support plate away from the support seat; the telescopic end of the electric push rod is fixedly connected to the connecting plate; during operation, when the electromagnet column adsorbs the metal sheet on the surface of the guide plate, the electric push rod on the surface of the support plate will lift the support plate, and the lifted support plate will also lift the connecting column, the electromagnet column and the guide plate adsorbed by the electromagnet column. When the guide plate adsorbed by the electromagnet column is transferred to the placement position, the electric push rod on the support plate contracts, so that the support plate drives the connecting plate, the connecting column and the electromagnet column to press the guide plate against the surface of the workpiece, so as to facilitate the electromagnet block on the surface of the guide plate to adsorb on the surface of the workpiece. By pulling the guide plate away from the surface of the workpiece during the transfer of the guide plate, it is possible to avoid collision between the guide plate and the guide plate still adsorbed on the surface of the workpiece during the process of driving the guide plate to rotate, resulting in the detachment of the guided plate.

[0010] Preferably, an arc plate is fixedly connected to one side surface of the support seat close to the rotating column and at the bottom position; rubber pads are fixedly connected to both sides of the arc plate; during operation, when the connecting plate rotates to be parallel to the guide plate, the surface of the connecting plate will contact the rubber pad. Through the support and limit of the arc plate and the rubber pad on the connecting plate, it is possible to prevent the connecting plate from rotating excessively, resulting in the connecting plate not rotating to be parallel to the guide plate, thereby ensuring that the electromagnet column can normally adsorb the metal sheet in the middle of the guide plate. At the same time, the rubber pad can also play a role in protecting the connecting plate and reducing the damage suffered by the connecting plate when it collides with the arc plate.

[0011] Preferably, a sleeve is fixedly connected to one end of the connecting plate away from the rotating column; the connecting column is rotatably connected to the inner wall of the sleeve; a mounting plate is slidably connected to one side surface of the arc plate away from the support seat; a main gear is fixedly connected to one side surface of the mounting plate close to the rotating column, and the main gear is rotatably connected to the end face of the rotating column; a pair of sub-gears are rotatably connected to one side surface of the connecting plate close to the main gear; the two sub-gears are meshed with each other, and one of the sub-gears is meshed with the main gear, and the other sub-gear is belt-driven with the connecting column; during operation, when the connecting plate rotates, since the main gear fixedly connected to the mounting plate does not rotate, the sub-gear will rotate on the surface of the main gear, and then the sub-gear meshed with the main gear will drive the other sub-gear to rotate, and then the sub-gear not meshed with the main gear will drive the connecting column to rotate in the sleeve through the belt, and then the connecting column will drive the electromagnet column and the guide plate adsorbed by the electromagnet to rotate together. Therefore, during the process of the connecting plate driving the guide plate to transfer, the guide plate can always remain horizontal, thereby reducing the rotation radius when the connecting plate drives the guide plate to rotate, and further reducing the probability of the guide plate colliding with other parts of the workpiece during the transfer process, and expanding the application range of the embodiment of the present invention.

[0012] Preferably, a baffle is fixedly connected to one end of the guide plate near the bottom; a docking groove is formed at a position near the bottom of the end of the guide plate away from the baffle; the baffle is adapted to the docking groove; during operation, when the guide plate is driven by the connecting plate and transferred to the end of another guide plate, the baffles and the connecting grooves at the ends of the two guide plates will be mutually adapted, that is, the baffle is snapped into the connecting groove, so that the guide plates can be kept on the same horizontal line, avoiding the skew of the guide plates and affecting the welding of the seam between the workpiece and the base by the welding torch.

[0013] Preferably, the connecting component includes a sliding plate; the sliding plate is arranged inside the sliding groove; one end of the sliding plate near the bottom is rotatably connected to the welding torch; during operation, when the user needs to align the welding torch with the seam between the workpiece and the base, the user can rotate the welding torch at the end of the sliding plate so that the welding torch forms an angle of 15-20 degrees with the seam to be welded, so as to ensure that the solder can be fully melted and fill the seam.

[0014] Preferably, a through groove is formed at the middle position of the surface of the sliding plate; a pair of symmetrically arranged knobs are rotatably connected to the bottom of the sliding groove, and the knobs are located in the through groove; a pair of symmetrically arranged wedge-shaped plates are fixedly connected to both sides of the knobs, and the wedge-shaped plates are located between the sliding plate and the bottom of the sliding groove; during operation, when the user needs to adjust the position of the welding torch, the user can directly move the sliding plate and the welding torch. After the welding torch slides to a suitable position, the user can rotate the knob, drive the wedge-shaped plate to rotate through the knob, and finally make the wedge-shaped plate enter the gap between the sliding plate and the sliding groove, so as to press the surface of the sliding plate against the surface of the support seat, thereby realizing the fixation of the positions of the sliding plate and the welding torch, and facilitating the adjustment of the user.

[0015] Preferably, a pair of elastic pieces are fixedly connected to both ends of the bottom of the sliding groove; the paired elastic pieces are symmetric about the through groove; one end of the elastic piece away from the bottom of the sliding groove is slidably connected to the sliding plate; during operation, when the wedge-shaped plate disengages from the gap between the sliding plate and the sliding groove, the elastic pieces at the bottom of the sliding groove will still push the sliding plate against the surface of the support seat, so that the sliding plate will not slide rapidly along the sliding groove, avoiding the user's hand slipping during the process of adjusting the position of the welding torch and causing the sliding plate and the welding torch to slide rapidly, resulting in a collision and damage to the welding torch.

[0016] Preferably, the driving assembly includes a pair of driving gears; the driving gears are rotatably connected to the moving seat; a plurality of uniformly arranged card slots are formed on the surface of the guide plate at positions corresponding to the two driving gears; the driving gears are meshed with the card slots; the two driving gears are synchronously driven by a bi-axial motor; during operation, when the moving seat needs to move along the guide plate, the bi-axial motor drives the driving gears at both ends to rotate, and then drives the moving seat to move along the guide plate through the rotation of the driving gears and their meshing with the card slots. Since the movement of the moving seat is realized through the meshing of the driving gears and the card slots, the probability of the moving seat slipping during movement is reduced, so that the moving seat is more stable when driving the welding torch to move, and the welding effect at the joint is guaranteed.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the mobile welding robot of the present invention, the guide plate far from the advancing direction of the moving seat is transferred to one end close to the advancing direction through the transfer assembly, so that the moving seat can continue to move forward along the guide plate, thus avoiding the user from frequently disassembling and installing the guide plate, reducing the work process, improving the welding efficiency. At the same time, the automatic extension of the guide plate also enables the embodiments of the present invention to cope with workpieces of different lengths, expanding the application scope of the embodiments of the present invention.

[0019] 2. For the mobile welding robot of the present invention, the power-off of the electromagnet is controlled by the microcomputer, the first contact piece and the second contact piece, so that when transferring the guide plate, the electromagnet column, the connecting column, the connecting plate and the rotating column can be more relaxed, and there is no need to resist the adsorption force between the electromagnet block and the workpiece, thereby reducing the pressure on the servo motor and extending its service life.

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0029] Such as Figures 1 to 2As shown in the figure, a mobile welding robot according to an embodiment of the present invention includes three guide plates 1; the three guide plates 1 are arranged end to end in sequence; a pair of electromagnet blocks 2 are fixedly connected to one side surface of the guide plate 1; a moving seat 3 is slidably connected to the side surface of the guide plate 1 away from the electromagnet block 2; a driving component is installed on the surface of the moving seat 3; the driving component is used to drive the moving seat 3 to move on the surface of the guide plate 1; an installation seat 4 is fixedly connected to the side surface of the moving seat 3 away from the guide plate 1; a chute 5 is opened on the side surface of the installation seat 4 away from the moving seat 3; a connecting component is installed in the chute 5; a welding torch 6 is installed at the end of the connecting component; the connecting component is used to connect the welding torch 6 and the installation seat 4; a support seat 7 is installed on the side surface of the installation seat 4 away from the moving seat 3; a transfer component is installed on the side surface of the support seat 7 away from the installation seat 4; the transfer component is used to transfer the guide plate 1 on one side of the moving seat 3 to the other side of the moving seat 3, and a microcomputer is arranged inside the support seat 7, and this microcomputer is used to control each execution component in the present invention; during work, when the user needs to weld multiple workpieces on the same base, the embodiment of the present invention can be used. First, the user needs to turn on the electromagnet block 2 and adsorb the three guide plates 1 connected end to end in sequence on the surface of the workpiece, and align the welding torch 6 with the joint between the base and the workpiece. Then, the driving component drives the moving seat 3, the installation seat 4, the support seat 7 and the welding torch 6 to move along the guide plate 1, so that the welding torch 6 smoothly passes through the joint, thereby completing the welding operation between the multiple workpieces and the base. When the moving seat 3 moves to the middle position of the middle guide plate among the three guide plates 1, the transfer component on the surface of the support seat 7 will transfer the guide plate 1 away from the advancing direction of the moving seat 3 to the end close to the advancing direction, so that the moving seat 3 can continue to move along the guide plate 1, thereby avoiding the user from frequently disassembling and installing the guide plate 1, reducing the work process, improving the welding efficiency. At the same time, automatically extending the guide plate 1 can also enable the embodiment of the present invention to cope with workpieces of different lengths, expanding the application range of the embodiment of the present invention.

[0030] As Figures 1 to 4As shown, the transfer component includes a rotating column 8; the rotating column 8 is rotatably connected to the support base 7, and the rotating column 8 is driven by a servo motor inside the support base 7; a connecting plate 9 is mounted on the surface of the rotating column 8; a connecting column 10 is fixedly connected to one end of the connecting plate 9 away from the rotating column 8; an electromagnet column 11 is mounted at one end of the connecting column 10 close to the guide plate 1; a metal sheet 12 is fixedly connected to the surface of the guide plate 1 at a position corresponding to the electromagnet column 11, and the metal sheet 12 is made of a magnetizable metal material; a contact piece one 13 is fixedly connected to the side surface of the electromagnet column 11 close to the guide plate 1; a contact piece two 14 is fixedly connected to the surface of the guide plate 1 at a position corresponding to the contact piece one 13; the microcomputer can control the energization and de-energization of the electromagnet block 2 through the contact of the contact piece one 13 and the contact piece two 14; during operation, when it is necessary to transfer the guide plate 1, first, the moving seat 3, the mounting seat 4, and the support base 7 will move to the middle guide plate 1, then the servo motor drives the rotating column 8 to rotate, and then the rotating column 8 drives the connecting plate 9 to rotate, so that the connecting plate 9 rotates to the side away from the traveling direction. Subsequently, the electromagnet column 11 at the end of the connecting column 10 will adsorb the metal sheet 12 on the surface of the guide plate 1, and make the contact piece one 13 on the surface of the electromagnet column 11 contact the contact piece two 14 on the surface of the guide plate 1, thereby completing the connection of the contact piece one 13 and the contact piece two 14. The microcomputer at the support base 7 controls the electromagnet block 2 to cut off the power, so that the guide plate 1 is separated from the adsorption on the surface of the workpiece. Subsequently, the rotating column 8 drives the connecting plate 9 and the connecting column 10 to rotate 90 degrees, and then the moving seat 3 drives the mounting seat 4, the support base 7, the rotating column 8, the connecting plate 9, the connecting column 10, the electromagnet column 11, and the guide plate 1 adsorbed by the electromagnet column 11 to move together. When moving to the middle of the last guide plate 1 in the traveling direction, the rotating column 8 drives the connecting plate 9, the connecting column 10, the electromagnet column 11, and the guide rotated by the electromagnet column 11 to the traveling direction of the moving seat 3. Subsequently, the microcomputer controls the electromagnet block 2 to start, so that the guide plate 1 is adsorbed to the surface of the workpiece again, so that the three guide plates 1 are connected end to end in sequence again. Then the electromagnet column 11 is powered off to release the adsorption on the metal sheet 12 and the guide plate 1. By continuously circulating the above process, the guide plate 1 can be continuously extended in the traveling direction of the moving seat 3, so that the moving seat 3 moving on the guide plate 1 can drive the welding torch 6 to continuously weld the seam between the workpiece and the base. The microcomputer controls the power-off of the electromagnet through the contact piece one 13 and the contact piece two 14, so that when transferring the guide plate 1, the electromagnet column 11, the connecting column 10, the connecting plate 9, and the rotating column 8 can be more relaxed and no longer need to resist the adsorption force between the electromagnet block 2 and the workpiece, thereby reducing the pressure on the servo motor and extending its service life.

[0031] As Figures 3 to 4As shown, a slide bar 15 is slidably connected to one end of the rotating column 8 away from the mounting base 4; the slide bar 15 is fixedly connected to the connecting plate 9; on one side of the surface of the rotating column 8 close to the support base 7, a support plate 16 is fixedly connected, and the support plate 16 is slidably connected to the surface of the support base 7; on the surface of the support plate 16 away from the support base 7, an electric push rod 17 is fixedly connected; the telescopic end of the electric push rod 17 is fixedly connected to the connecting plate 9; during operation, when the electromagnet column 11 adsorbs the metal sheet 12 on the surface of the guide plate 1, the electric push rod 17 on the surface of the support plate 16 will lift the support plate 16, and the lifted support plate 16 will also lift the connecting column 10, the electromagnet column 11 and the guide plate 1 adsorbed by the electromagnet column 11. When the guide plate 1 adsorbed by the electromagnet column 11 is transferred to the placement position, the electric push rod 17 on the support plate 16 contracts, so that the support plate 16 drives the connecting plate 9, the connecting column 10 and the electromagnet column 11 to press the guide plate 1 against the surface of the workpiece, so as to facilitate the electromagnet block 2 on the surface of the guide plate 1 to adsorb on the surface of the workpiece. By pulling the guide plate 1 away from the surface of the workpiece during the transfer of the guide plate 1, it is possible to avoid collision between the guide plate 1 and the guide plate 1 still adsorbed on the surface of the workpiece during the rotation of the guide plate 1, resulting in the detachment of the guide plate 1.

[0032] As Figure 3 shown, on one side surface of the support base 7 close to the rotating column 8 and at the bottom position, an arc-shaped plate 18 is fixedly connected; rubber pads 19 are fixedly connected to both sides of the arc-shaped plate 18; during operation, when the connecting plate 9 rotates to be parallel to the guide plate 1, the surface of the connecting plate 9 will contact the rubber pads 19. Through the support and limitation of the connecting plate 9 by the arc-shaped plate 18 and the rubber pads 19, it is possible to avoid excessive rotation of the connecting plate 9, resulting in the connecting plate 9 not being able to rotate to be parallel to the guide plate 1, thus ensuring that the electromagnet column 11 can normally adsorb the metal sheet 12 in the middle of the guide plate 1. At the same time, the rubber pads 19 can also play a role in protecting the connecting plate 9 and reducing the damage suffered by the connecting plate 9 when it collides with the arc-shaped plate 18.

[0033] As Figure 1 and Figure 3As shown in the figure, a sleeve 20 is fixedly connected to one end of the connecting plate 9 away from the rotating column 8; the connecting column 10 is rotatably connected to the inner wall of the sleeve 20; a mounting plate 21 is slidably connected to the surface of the arc-shaped plate 18 away from the support base 7; a main gear 22 is fixedly connected to the surface of the mounting plate 21 close to the rotating column 8, and the main gear 22 is rotatably connected to the end face of the rotating column 8; a pair of secondary gears 23 are rotatably connected to the surface of the connecting plate 9 close to the main gear 22; the two secondary gears 23 are meshed with each other, and one of the secondary gears 23 is meshed with the main gear 22, and the other secondary gear 23 is belt-driven with the connecting column 10; during operation, when the connecting plate 9 rotates, since the main gear 22 fixedly connected to the mounting plate 21 does not rotate, the secondary gear 23 will rotate on the surface of the main gear 22, and then the secondary gear 23 meshed with the main gear 22 will drive the other secondary gear 23 to rotate, and then the secondary gear 23 not meshed with the main gear 22 will drive the connecting column 10 to rotate in the sleeve 20 through a belt, and then the connecting column 10 will drive the electromagnet column 11 and the guide plate 1 adsorbed by the electromagnet to rotate together. Furthermore, when the connecting plate 9 drives the guide plate 1 to transfer, the guide plate 1 can always remain horizontal, thereby reducing the rotation radius when the connecting plate 9 drives the guide plate 1 to rotate, and further reducing the probability that the guide plate 1 collides with other parts of the workpiece during the transfer process, expanding the applicable range of the embodiment of the present invention.

[0034] As Figure 1 , Figure 2 and Figure 6 shown, a baffle 24 is fixedly connected to one end of the guide plate 1 and close to the bottom position; a docking groove 25 is formed at one end of the guide plate 1 away from the baffle 24 and close to the bottom position; the baffle 24 is adapted to the docking groove 25; during operation, when the guide plate 1 is driven by the connecting plate 9 and transferred to the end of another guide plate 1, the baffles 24 and the connecting grooves at the ends of the two guide plates 1 will be mutually adapted, that is, the baffle 24 is inserted into the connecting groove, so that the guide plates 1 can be kept on the same horizontal line, avoiding the guide plate 1 from being skewed and affecting the welding of the workpiece and the base joint by the welding torch 6.

[0035] As Figure 1 , Figure 3 and Figure 5 shown, the connecting component includes a sliding plate 26; the sliding plate 26 is arranged inside the sliding groove 5; one end of the sliding plate 26 close to the bottom is rotatably connected to the welding torch 6; during operation, when the user needs to align the welding torch 6 with the joint between the workpiece and the base, the user can rotate the welding torch 6 at the end of the sliding plate 26 so that the welding torch 6 forms an angle of 15-20 degrees with the joint to be welded, so as to ensure that the solder can be fully melted and fill the joint.

[0036] As Figure 5As shown, the connecting component includes a sliding plate 26; the sliding plate 26 is arranged inside the sliding groove 5; one end of the sliding plate 26 near the bottom is rotatably connected to the welding torch 6; during operation, when the user needs to align the welding torch 6 with the joint between the workpiece and the base, the user can rotate the welding torch 6 at the end of the sliding plate 26 so that the welding torch 6 forms an angle of 15 - 20 degrees with the joint to be welded, ensuring that the solder can be fully melted and fill the joint.

[0037] As Figure 5 shown, a pair of elastic pieces 30 are fixedly connected to the bottom of the sliding groove 5 at both ends; the paired elastic pieces 30 are symmetric about the through groove 27; one end of the elastic piece 30 away from the bottom of the sliding groove 5 is slidably connected to the sliding plate 26; during operation, when the wedge-shaped plate 29 disengages from the gap between the sliding plate 26 and the sliding groove 5, the elastic pieces 30 at the bottom of the sliding groove 5 still push the sliding plate 26 against the surface of the support seat 7, preventing the sliding plate 26 from quickly sliding down along the sliding groove 5 and avoiding the user from losing control during the process of adjusting the position of the welding torch 6, which may cause the sliding plate 26 and the welding torch 6 to quickly slide down and collide, resulting in damage to the welding torch 6.

[0038] As Figure 1 and Figure 6 shown, the driving component includes a pair of driving gears 31; the driving gears 31 are rotatably connected to the moving seat 3; a plurality of uniformly arranged card slots 32 are formed on the surface of the guiding plate 1 at positions corresponding to the two driving gears 31; the driving gears 31 are meshed with the card slots 32; the two driving gears 31 are synchronously driven by a double-shaft motor; during operation, when the moving seat 3 needs to move along the guiding plate 1, the double-shaft motor drives the driving gears 31 at both ends to rotate, and then drives the moving seat 3 to move along the guiding plate 1 through the rotation of the driving gears 31 and their meshing with the card slots 32. Since the movement of the moving seat 3 is realized through the meshing of the driving gears 31 and the card slots 32, the probability of the moving seat 3 slipping during movement is reduced, making the moving seat 3 move more smoothly when driving the welding torch 6, and thus ensuring the welding effect of the joint.

[0039] During operation, when the user needs to weld multiple workpieces onto the same base, the embodiment of the present invention can be used. First, the user needs to turn on the electromagnet block 2, and adsorb the three guide plates 1 connected end to end in sequence onto the surface of the workpiece, and align the welding torch 6 with the joint between the base and the workpiece. Then, the driving assembly drives the moving seat 3, the mounting seat 4, the support seat 7, and the welding torch 6 to move along the guide plate 1, so that the welding torch 6 smoothly passes through the joint, thereby completing the welding operation between the multiple workpieces and the base. When the moving seat 3 moves to the middle position of the middle one of the three guide plates 1, the transfer assembly on the surface of the support seat 7 will transfer the guide plate 1 away from the advancing direction of the moving seat 3 to the end close to the advancing direction, so that the moving seat 3 can continue to move forward along the guide plate 1, thus avoiding the user from frequently disassembling and installing the guide plate 1, reducing the work process, improving the welding efficiency. At the same time, automatically extending the guide plate 1 can also enable the embodiment of the present invention to cope with workpieces of different lengths, expanding the scope of application of the embodiment of the present invention.

[0040] When it is necessary to transfer the guiding plate 1, first, the moving seat 3, the mounting seat 4, and the supporting seat 7 will move to the middle guiding plate 1. Then, the servo motor drives the rotating column 8 to rotate, and the rotating column 8 drives the connecting plate 9 to rotate, so that the connecting plate 9 rotates to the side away from the traveling direction. Subsequently, the electromagnet column 11 at the end of the connecting column 10 will adsorb the metal sheet 12 on the surface of the guiding plate 1, and make the contact piece 13 on the surface of the electromagnet column 11 contact the contact piece 14 on the surface of the guiding plate 1, thereby completing the connection between the contact piece 13 and the contact piece 14. The microcomputer at the supporting seat 7 controls the electromagnet block 2 to cut off the power, so that the guiding plate 1 is detached from the adsorption on the workpiece surface. Subsequently, the rotating column 8 drives the connecting plate 9 and the connecting column 10 to rotate 90 degrees. Then, the moving seat 3 drives the mounting seat 4, the supporting seat 7, the rotating column 8, the connecting plate 9, the connecting column 10, the electromagnet column 11, and the guiding plate 1 adsorbed by the electromagnet column 11 to move together. When moving to the middle of the last guiding plate 1 in the advancing direction, the rotating column 8 drives the connecting plate 9, the connecting column 10, the electromagnet column 11, and the guiding plate adsorbed by the electromagnet column 11 to rotate to the advancing direction of the moving seat 3. Subsequently, the microcomputer controls the electromagnet block 2 to start, so that the guiding plate 1 is adsorbed to the workpiece surface again, making the three guiding plates 1 connected end to end in sequence again. Then, the electromagnet column 11 cuts off the power, releasing the adsorption on the metal sheet 12 and the guiding plate 1. By continuously circulating the above process, the guiding plate 1 can be continuously extended in the advancing direction of the moving seat 3, so that the moving seat 3 moving on the guiding plate 1 can drive the welding torch 6 to continuously weld the seam between the workpiece and the base. The microcomputer controls the power-off of the electromagnet through the contact piece 13 and the contact piece 14, so that when transferring the guiding plate 1, the electromagnet column 11, the connecting column 10, the connecting plate 9, and the rotating column 8 can be more relaxed, no longer need to resist the adsorption force between the electromagnet block 2 and the workpiece, thereby reducing the pressure on the servo motor and extending its service life.

[0041] After the electromagnet column 11 adsorbs the metal sheet 12 on the surface of the guiding plate 1, the electric push rod 17 on the surface of the support plate 16 will lift the support plate 16, and the lifted support plate 16 will also lift the connecting column 10, the electromagnet column 11, and the guiding plate 1 adsorbed by the electromagnet column 11. When the guiding plate 1 adsorbed by the electromagnet column 11 is transferred to the placement position, the electric push rod 17 on the support plate 16 contracts, so that the support plate 16 drives the connecting plate 9, the connecting column 10, and the electromagnet column 11 to press the guiding plate 1 against the workpiece surface, so as to facilitate the adsorption of the electromagnet block 2 on the surface of the guiding plate 1 on the workpiece surface. By pulling the guiding plate 1 away from the workpiece surface during the process of transferring the guiding plate 1, it is possible to avoid the collision between the guiding plate 1 and the guiding plate 1 still adsorbed on the workpiece surface during the process of driving the guiding plate 1 to rotate, resulting in the detachment of the guided plate 1.

[0042] When the connecting plate 9 rotates to be parallel to the guiding plate 1, the surface of the connecting plate 9 will come into contact with the rubber pad 19. Through the support and limitation of the arc-shaped plate 18 and the rubber pad 19 on the connecting plate 9, it can prevent the connecting plate 9 from rotating excessively, resulting in the connecting plate 9 not rotating to be parallel to the guiding plate 1. Furthermore, it can ensure that the electromagnet column 11 can normally adsorb the metal sheet 12 in the middle of the guiding plate 1. At the same time, the rubber pad 19 can also play a role in protecting the connecting plate 9 and reducing the damage suffered by the connecting plate 9 when it collides with the arc-shaped plate 18.

[0043] When the connecting plate 9 rotates, since the main gear 22 fixedly connected to the mounting plate 21 does not rotate, the secondary gear 23 will rotate on the surface of the main gear 22. Then, the secondary gear 23 meshing with the main gear 22 will drive another secondary gear 23 to rotate. Then, the secondary gear 23 not meshing with the main gear 22 will drive the connecting column 10 to rotate in the sleeve 20 through a belt. Then, the connecting column 10 will drive the electromagnet column 11 and the guiding plate 1 adsorbed by the electromagnet to rotate together. Furthermore, when the connecting plate 9 drives the guiding plate 1 to transfer, the guiding plate 1 can always remain horizontal, thereby reducing the rotation radius when the connecting plate 9 drives the guiding plate 1 to rotate, and further reducing the probability of the guiding plate 1 colliding with other parts of the workpiece during the transfer process, expanding the applicable range of the embodiment of the present invention.

[0044] When the guiding plate 1 is driven by the connecting plate 9 and transferred to the end of another guiding plate 1, the baffles 24 and the connecting grooves at the ends of the two guiding plates 1 will be mutually adapted, that is, the baffle 24 is snapped into the connecting groove, so that the guiding plates 1 can be kept on the same horizontal line, avoiding the guiding plate 1 from being skewed and affecting the welding of the workpiece and the base joint by the welding torch 6.

[0045] When the user needs to align the welding torch 6 with the joint between the workpiece and the base, the user can rotate the welding torch 6 at the end of the sliding plate 26 so that the welding torch 6 forms an angle of 15 - 20 degrees with the joint to be welded, so as to ensure that the solder can be fully melted and fill the joint.

[0046] When the user needs to adjust the position of the welding torch 6, the user can directly move the sliding plate 26 and the welding torch 6. After the welding torch 6 slides to a suitable position, the user can rotate the knob 28. By driving the wedge-shaped plate 29 to rotate through the knob 28 and making the wedge-shaped plate 29 finally enter the gap between the sliding plate 26 and the sliding groove 5, the surface of the sliding plate 26 can be pressed against the surface of the support seat 7, thereby realizing the fixation of the positions of the sliding plate 26 and the welding torch 6, and facilitating the adjustment of the user.

[0047] When the wedge plate 29 disengages from the gap between the sliding plate 26 and the chute 5, the elastic piece 30 at the bottom of the chute 5 still pushes the sliding plate 26 against the surface of the support seat 7, so that the sliding plate 26 will not slide rapidly along the chute 5, preventing the user from losing their grip during the process of adjusting the position of the welding torch 6, which may cause the sliding plate 26 and the welding torch 6 to slide rapidly and collide, resulting in damage to the welding torch 6.

[0048] When the moving seat 3 needs to move along the guide plate 1, the biaxial motor drives the driving gears 31 at both ends to rotate. Then, through the rotation of the driving gears 31 and their meshing with the card slots 32, the moving seat 3 is driven to move along the guide plate 1. Since the movement of the moving seat 3 is achieved through the meshing of the driving gears 31 and the card slots 32, the probability of the moving seat 3 slipping during movement is reduced, making the moving seat 3 move more smoothly when driving the welding torch 6, and thus ensuring the welding effect at the joint.
