DETAILED DESCRIPTION

[0043] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can be varied in a wide range of embodiments, none of which depart from the scope of the present application, and that the description and drawings are to be considered as illustrative in nature, and not restrictive.

[0044] In the description of the present application, it should be understood that the indications of direction or position relationship (such as up, down, left, right, front and back, etc.) in the embodiments shown in the drawings are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated devices or elements must have a particular orientation, be constructed and operated in a particular orientation. When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indications of direction also change accordingly.

[0045] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered sequence. Thus, features referring to "first", "second" etc. can include one or more of the features, explicitly or implicitly. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise explicitly specified.

[0046] In the production and manufacture of large ships, bridges and other equipment, it is often necessary to weld long straight welds. For example, in the manufacture of large ships, bulb steel, T-shaped steel or I-shaped steel is often used as the skeleton of the ship, and the skeleton of the ship needs to be welded with the deck plate and the deck plate of the ship, etc. The long straight welds need to be welded between the skeleton and the plate. When welding long straight welds, track type collaborative welding robots are usually used for welding. Track type collaborative welding robots refer to automated equipment that moves along a predetermined track to perform welding tasks. They can cover a larger working range while maintaining stable welding, and can work collaboratively with workers, and in some cases can even directly replace manual high-precision welding operations. Using track type collaborative welding robots to weld long straight welds has at least the following advantages: 1. Improve work efficiency: automated processes reduce setup time and waiting time; 2. Improve welding quality: precise control of welding speed and other parameters helps achieve more consistent and high-quality welding results; 3. Reduce labor intensity: reduce the physical burden of workers, especially for repetitive work or work in difficult-to-reach locations; 4. Enhance safety: reduce the opportunity for workers to directly contact hazardous environments such as high temperatures, smoke, etc.

[0047] Referring to Figure 1 and Figure 10 , the existing track type collaborative welding robot has the problems of heavy track weight and troublesome connection with the device for fixing the track (i.e. the support structure 200 below), which makes it inconvenient to carry and lay the track of the existing portable track type collaborative welding robot. The present application provides a welding device 100, which includes a welding track 10 and a welding device 30, the welding track 10 is detachably connected with the support structure 200 (such as the ship skeleton described above), and the welding device 30 can move along the length direction of the welding track 10, so that the welding device 30 can move under the guidance of the welding track 10 and weld long straight welds, improving welding accuracy.

[0048] Referring to Figure 3 and Figures 5 to 9The welding rail 10 comprises the rail assembly 1 and the connecting assembly 2. The rail assembly 1 comprises a plurality of rail segments 11 which are sequentially arranged along the length direction and detachably spliced together to form a rail, so that the rail can be split into a plurality of rail segments 11, thereby making the weight of each rail segment 11 smaller and facilitating the workers to carry and disassemble.

[0049] The plurality of rail segments 11 are of the same structure, so that the rail segments 11 do not need to be arranged in a set order when spliced, i.e., the positions of the rail segments 11 can be exchanged, facilitating the splicing between the rail segments 11.

[0050] Each rail segment 11 has a U-shaped cross section, and slide rails 113 are formed on the inner walls of the two sides of the rail segment 11 for sliding connection with the welding equipment 30. The rail segment 11 comprises a first rail end 111 and a second rail end 112 along the length direction, and when the plurality of rail segments 11 are sequentially spliced, the second rail end 112 of a previous rail segment 11 is connected with the first rail end 111 of a subsequent rail segment 11, so that the plurality of rail segments 11 form a long strip-shaped rail, and the end portions of the slide rails 113 on the adjacent two rail segments 11 are just butt-jointed together.

[0051] The rail segment 11 is preferably of an aluminum structure or an aluminum alloy structure, which has the characteristic of light weight, further reducing the weight of each rail segment 11, making it more convenient for workers to carry, and also ensuring the stress strength of the rail segment 11 and the service life of the rail segment 11. In other embodiments, the rail segment 11 can also be of other metal material structures, such as a copper material rail or a steel material rail.

[0052] The first rail end 111 is provided with a positioning recess 13, and the opening of the positioning recess 13 faces outward from the end face of the first rail end 111. The second rail end 112 is provided with a positioning protrusion 14 which is arranged in cooperation with the positioning recess 13. The positioning protrusion 14 protrudes outward from the end face of the second rail end 112, and the position of the positioning protrusion 14 corresponds to the position of the positioning recess 13 of the adjacent rail segment 11. When the plurality of rail segments 11 are sequentially spliced together, the positioning protrusion 14 is inserted into the positioning recess 13 of the adjacent rail segment 11, achieving the alignment between the adjacent two rail segments 11, improving the precision of the spliced rail, so that the welding equipment 30 can smoothly move along the length direction of the rail, thereby improving the welding quality of the welding equipment 30 in the process of welding the weld joint.

[0053] The positioning groove 13 is directly formed on the first rail end 111 of the rail segment 11, or the positioning groove 13 is formed on the first rail end 111 of the rail segment 11 by fixing a positioning member with the positioning groove 13 on the first rail end 111 of the rail segment 11. Similarly, the positioning protrusion 14 can be an integral structure of the rail segment 11, or the positioning protrusion 14 is separately arranged from the rail segment 11, and the positioning protrusion 14 is formed on the second rail end 112 of the rail segment 11 by fixing a positioning member with the positioning protrusion 14 on the second rail end 112 of the rail segment 11. In other embodiments, the positions of the positioning groove 13 and the positioning protrusion 14 can be interchanged, that is, the positioning groove 13 is arranged on the second rail end 112 of the rail segment 11, and the positioning protrusion 14 is arranged on the first rail end 111 of the rail segment 11.

[0054] Preferably, the positioning protrusion 14 is provided with a guide inclined surface at an end away from the rail segment 11, so that the size of the positioning protrusion 14 gradually decreases from the end close to the rail segment 11 to the end away from the rail segment 11, thereby facilitating the insertion of the positioning protrusion 14 into the positioning groove 13.

[0055] The rail assembly 1 further comprises a buckle seat 15 and a buckle lock 16. The buckle seat 15 is arranged on the first rail end 111, and the buckle lock 16 is arranged on the second rail end 112. The position of the buckle lock 16 corresponds to the position of the buckle seat 15. When a plurality of rail segments 11 are connected in sequence, the buckle lock 16 is buckled with the buckle seat 15 of the adjacent rail segment 11, thereby achieving the fixed connection between the two adjacent rail segments 11, and further achieving the splicing of the entire rail assembly 1. The two adjacent rail segments 11 are connected through the buckle seat 15 and the buckle lock 16, so that the connection can be achieved only by pulling the buckle lock 16, which is convenient to operate.

[0056] The buckle seat 15 and the buckle lock 16 are arranged on the outer side of the rail segment 11 along the width direction thereof, so that the staff can conveniently operate the buckle lock 16 to buckle with the buckle seat 15, and the buckle seat 15 and the buckle lock 16 will not affect the movement of the welding equipment 30 on the slide rail 113. Figure 5 In the embodiment shown, the buckle seat 15 and the buckle lock 16 are arranged on both sides of each rail segment 11 along the width direction thereof, so that the two adjacent rail segments 11 can be connected through the buckle lock 16 and the buckle seat 15 on both sides in the width direction, thereby improving the connection stability between the two adjacent rail segments 11. Moreover, when the support structure 200 is a single T-shaped steel or a single I-shaped steel, and the rail of the welded rail 10 is laid along the length direction of the support structure 200, the buckle lock 16 and the buckle seat 15 will not affect the stability of the welded rail 10 after the welded rail 10 is connected to the support structure 200, thereby increasing the application scenarios of the welded rail 10.

[0057] Each track segment 11 is provided with a sliding groove 17 on both sides along the width direction of the track segment 11, the sliding groove 17 has a T-shaped cross section, and the length direction of the sliding groove 17 is consistent with the length direction of the track segment 11. The sliding groove 17 can be formed by opening a groove on both sides of the track segment 11 along the width direction, or the sliding groove 17 can be formed by fixing a linear guide rail on both sides of the track segment 11 along the width direction, and a guide groove on the guide rail forms the sliding groove 17. It should be noted that the cross section of the sliding groove 17 can also be other shapes, for example, the sliding groove 17 is a dovetail groove.

[0058] Referring to Figure 2 , Figure 3 and Figure 4 Each track segment 11 is provided with a connecting assembly 2 on both sides along the width direction of the track segment 11, the connecting assembly 2 includes a connecting piece 21 and a locking piece 22, the connecting piece 21 is in sliding connection with the sliding groove 17 on the track segment 11, and the connecting piece 21 can move along the length direction of the track segment 11 to adjust the relative position between the connecting piece 21 and the support structure 200. The locking piece 22 is connected with the connecting piece 21 and the track, and the locking piece 22 can lock the connecting piece 21 on the track.

[0059] When the track assembly 1 is disassembled to form a plurality of track segments 11, the connecting assembly 2 remains connected to the corresponding track segment 11, so that the connecting assembly 2 and the track segment 11 do not need to be reassembled next time, and the installation efficiency between the track segment 11 and the support structure 200 is improved. It should be noted that when the track assembly 1 is disassembled to form a plurality of track segments 11, the connecting assembly 2 can also be detached from the corresponding track segment 11 to reduce the weight of each track segment 11, so that the track segment 11 is further convenient to carry.

[0060] The connecting piece 21 includes a first sliding block 211 and a second sliding block 212. The shape of the first sliding block 211 is adapted to the shape of the sliding groove 17, and the first sliding block 211 is in sliding connection with the sliding groove 17. The width dimension of the second sliding block 212 is greater than the width of the opening of the sliding groove 17, the second sliding block 212 is arranged on the outer side of the track, and corresponds to the position of the first sliding block 211. The locking piece 22 is connected with the first sliding block 211 and the second sliding block 212, and can adjust the distance between the first sliding block 211 and the second sliding block 212, so that the first sliding block 211 and the second sliding block 212 are clamped on the edge of the sliding groove 17 of the track segment 11, and the connecting piece 21 is locked on the track segment 11 by the locking piece 22. When the first sliding block 211 and the second sliding block 212 are no longer clamped on the track segment 11 by adjusting the locking piece 22, the first sliding block 211 and the second sliding block 212 can move along the length direction of the sliding groove 17.

[0061] The connecting member 21 further comprises a connecting portion 213 fixed to the second sliding block 212, so that the connecting portion 213 moves together with the second sliding block 212 to adjust the relative position between the connecting portion 213 and the support structure 200. The welding rail 10 is detachably connected to the support structure 200 through the connecting portion 213 of the connecting member 21, so that the whole welding rail 10 is fixed to the support structure 200. Moreover, the relative position between the connecting member 21 and the support structure 200 is adjusted through the locking member 22, so that the connecting member 21 can be accurately connected to the support structure 200, which makes the connection more convenient and enables the welding rail 10 to be installed on support structures 200 of different specifications.

[0062] When the welding rail 10 is installed on the support structure 200, each rail segment 11 is first placed on the support structure 200, then the rail segments 11 are connected to each other, and then the position of the connecting portion 213 is adjusted so that the position of the connecting portion 213 corresponds to the connecting position of the support structure 200, and the connecting portion 213 is connected to the connecting position of the support structure 200, thereby fixing the welding rail 10 on the support structure 200.

[0063] The connecting portion 213 and the second sliding block 212 are preferably detachably connected, so that the type of the connecting portion 213 can be changed according to the specific structure of the support structure 200.

[0064] Referring to Figure 2 and Figure 4 In an embodiment, the connecting portion 213 comprises a quick clamp 2131 and a limiting block 2132 arranged at intervals, and the quick clamp 2131 and the limiting block 2132 are respectively connected to the second sliding block 212. The pressing head end of the quick clamp 2131 can move towards the limiting block 2132 to clamp the connecting portion 213 to the support structure 200, and the pressing head end of the quick clamp 2131 can also move away from the limiting block 2132 to release the support structure 200. When the connecting portion 213 is clamped to the support structure 200, the limiting block 2132 and the pressing head end of the quick clamp 2131 are respectively located on both sides of the support structure 200. In this embodiment, the connecting portion 213 is suitable for the case where the support structure 200 is formed by a plurality of T-shaped steel bars, I-shaped steel bars or bulb steel bars arranged at intervals along the length direction of the rail, and each T-shaped steel bar, I-shaped steel bar or bulb steel bar forms a position that can be clamped by the connecting portion 213.

[0065] In Figure 4In the shown embodiment, the first slider 211 and the second slider 212 of each connecting assembly 2 are provided with two pieces, and the positions of the two pieces of the second slider 212 correspond to the positions of the two pieces of the first slider 211 one by one. The second slider 212 and the first slider 211 corresponding in position are connected by at least one locking piece 22, so that the positions of the two pieces of the second slider 212 can be adjusted respectively to adjust the positions of the quick clamps 2131 and the limiting blocks 2132, and the distance between the quick clamps 2131 and the limiting blocks 2132 can be changed to adapt to support structures 200 of different sizes. It should be noted that the quick clamps 2131 and the limiting blocks 2132 can also be connected on the same second slider 212, so that the relative distance between the quick clamps 2131 and the limiting blocks 2132 is fixed, but the pressure head end on the quick clamps 2131 is movable, and thus by controlling the movement of the pressure head end of the quick clamps 2131, the connecting part 213 can be clamped on the support structure 200.

[0066] Referring to Figure 11 and Figure 12 In an embodiment, the connecting part 213 is a magnetic attraction piece, and the connecting part 213 can be magnetically attracted and fixed to the support structure 200, so that the connection between the welded track 10 and the support structure 200 is more convenient. The connecting part 213 in this embodiment is suitable for the case where the support structure 200 is a T-shaped steel, an I-shaped steel or a magnetically attractable metal plate. The top surface of the T-shaped steel, the I-shaped steel and the magnetically attractable metal plate is a plane, and when the welded track 10 is placed on the top surface of the support structure 200, the position of the connecting part 213 is moved to make the bottom surface of the connecting part 213 completely fit the top surface of the support structure 200, so as to ensure the contact area between the connecting part 213 and the support structure 200 and improve the stability of the connection. The support structure 200 can be formed by a plurality of T-shaped steels or I-shaped steels arranged at intervals along the length direction of the track; or the support structure 200 is a single T-shaped steel or a single I-shaped steel, the length direction of the support structure 200 is the same as the length direction of the track, and the width of the top surface of the support structure 200 is greater than or equal to the width of the welded track 10. When the welded track 10 is placed on the top surface of the support structure 200, the connecting part 213 of the welded track 10 can also be magnetically attracted and fixed to the top surface of the support structure 200.

[0067] Referring to Figure 12 and Figure 13In an embodiment, the locking member 22 is a quick-press screw structure. The locking member 22 comprises a connecting screw rod 224 and an eccentric handle 225. One end of the connecting screw rod 224 penetrates through the second sliding block 212 and is connected with the first sliding block 211. The eccentric handle 225 is rotationally connected at the end of the connecting screw rod 224 away from the first sliding block 211. The rotation axis of the eccentric handle 225 relative to the connecting screw rod 224 is perpendicular to the axis of the connecting screw rod 224. The eccentric handle 225 is provided with a handle limiting surface 226 at the end close to the connecting screw rod 224. When the eccentric handle 225 is rotated relative to the connecting screw rod 224 to the position where the handle limiting surface 226 abuts against the second sliding block 212, the first sliding block 211 and the second sliding block 212 are clamped to the edge of the sliding groove 17 of the track segment 11.

[0068] In detail, the eccentric handle 225 is provided with a cam structure at the outer surface of the end close to the connecting screw rod 224. The eccentric handle 225 is rotationally connected with the connecting screw rod 224 through the rotation axis. The handle limiting surface 226 is formed at the position where the distance between the outer surface of the end close to the connecting screw rod 224 of the eccentric handle 225 and the rotation axis is the largest. When the eccentric handle 225 is rotated relative to the connecting screw rod 224, the cam structure pushes the second sliding block 212 to move towards the first sliding block 211. When the eccentric handle 225 is rotated to the position where the handle limiting surface 226 abuts against the second sliding block 212, the distance between the first sliding block 211 and the second sliding block 212 is the smallest, and the first sliding block 211 and the second sliding block 212 are clamped to the edge of the sliding groove 17 of the track segment 11.

[0069] The connecting screw rod 224 is threadedly connected with the first sliding block 211, so that the connecting screw rod 224 can be rotated relative to the first sliding block 211 around the axis of the connecting screw rod 224 to adjust the fitting position between the connecting screw rod 224 and the first sliding block 211, thereby adjusting the distance between the handle limiting surface 226 and the first sliding block 211.

[0070] In an embodiment, a gasket 227 is sleeved on the connecting screw rod 224. The gasket 227 is arranged between the handle limiting surface 226 of the eccentric handle 225 and the second sliding block 212. The eccentric handle 225 pushes the second sliding block 212 to move towards the first sliding block 211 through the gasket 227. The gasket 227 can be a flexible structure or a rigid structure.

[0071] The end of the eccentric handle 225 away from the connecting screw rod 224 is a free end. The staff rotates the free end of the eccentric handle 225 to rotate the eccentric handle 225 around the rotation axis, thereby saving labor when rotating the eccentric handle 225 and not needing to use other tools, improving the convenience of operating the locking member 22, and thereby making the fixation of the welded track 10 more convenient.

[0072] Referring to Figure 4 and Figure 14In an embodiment, the locking member 22 is a handle screw structure. The locking member 22 comprises a screw 221 and a handle 222, the screw 221 comprises a first screw end 2211 and a second screw end 2212 connected along the length direction of the screw 221, the diameter of the second screw end 2212 is larger than that of the first screw end 2211, and a screw limiting surface 223 is formed between the first screw end 2211 and the second screw end 2212, so that the screw 221 forms a bolt structure. The first screw end 2211 penetrates through the second sliding block 212 and is threadedly connected with the first sliding block 211, by rotating the screw 221 around the axis of the screw 221, the screw limiting surface 223 is abutted against the second sliding block 212, and the second sliding block 212 is pushed to move towards the first sliding block 211, so that the first sliding block 211 and the second sliding block 212 are clamped on the edge of the sliding groove 17 of the track segment 11.

[0073] The handle 222 is fixed on the second screw end 2212, and the handle 222 and the screw 221 form an approximate L-shaped structure. The end of the handle 222 away from the screw 221 is a free end, and the staff pulls the free end of the handle 222 to rotate the screw 221 around the axis of the screw 221, so that it is more labor-saving to rotate the handle 222, and other tools are not needed, the convenience of operating the locking member 22 is improved, and the fixation of the welded track 10 is more convenient.

[0074] The handle 222 is preferably a ratchet handle with a direction switching switch, by adjusting the direction switching switch, when the direction switching switch is in a forward locking position, the ratchet handle can only twist the screw 221 in a forward direction; when the direction switching switch is in a reverse locking position, the ratchet handle can only twist the screw 221 in a reverse direction, thereby reducing the required space of the handle 222 when twisting the screw 221. It should be noted that the handle 222 can also be other ordinary handles, such as an L-shaped clamping handle, a key handle, etc.

[0075] Referring to Figure 1 and Figure 10 , the welding equipment 30 is detachably arranged on any track segment 11, that is, the welding equipment 30 can be detached from the track, so that the track segment 11 and the welding equipment 30 are transported respectively, the weight of the track segment 11 and the welding equipment 30 during transportation is reduced, and the transportation is more convenient.

[0076] Referring to Figure 15The welding equipment 30 includes a welding mechanism 3, a wire feeding mechanism 5, a drive mechanism 4, and a connector 6. The wire feeding mechanism 5 and the welding mechanism 3 are detachably connected to any track segment 11 and can move along the length of the track formed by splicing multiple track segments 11. The drive mechanism 4 is mounted on the welding mechanism 3 and connected to the track. The drive mechanism 4 drives the welding mechanism 3 to move along the length of the track and ensures the positional accuracy of the welding mechanism 3, thereby ensuring the welding accuracy of long straight welds. The connector 6 connects the welding mechanism 3 and the wire feeding mechanism 5, allowing the welding mechanism 3 to drive the wire feeding mechanism 5 to move together via the connector 6. It should be noted that the drive mechanism 4 can also be mounted on the wire feeding mechanism 5 and connected to the track, driving the wire feeding mechanism 5 to move along the length of the track, and the wire feeding mechanism 5 drives the welding mechanism 3 to move together via the connector 6.

[0077] The welding mechanism 3 includes a collaborative arm slide 31 and a welding robot 32. The collaborative arm slide 31 is detachably connected to the track, and the welding robot 32 is detachably connected to the collaborative arm slide 31. This allows the collaborative arm slide 31 and the welding robot 32 to be disassembled and assembled separately when the welding mechanism 3 is disassembled, reducing the weight of individual parts during disassembly and assembly, and making transportation more convenient.

[0078] See Figures 16 to 18 The collaborative arm slide 31 includes a mounting plate 311 and second bearings 312 spaced apart on the bottom surface of the mounting plate 311. At least three second bearings 312 are arranged, and they are divided into two groups along the width direction of the mounting plate 311, which is the same as the width direction of the track segment 11. Figure 17 In the illustrated embodiment, each set of second bearings 312 includes two second bearings 312. A second annular groove is formed on the circumferential outer surface of each second bearing 312. The second annular grooves of the two sets of second bearings 312 are respectively configured to engage with slide rails 113 on the inner walls of both sides of the track segment 11, so that after the cooperative arm slide 31 is installed on the track segment 11, it can only move along the length direction of the track segment 11. When it is necessary to remove the cooperative arm slide 31 from the track segment 11, the cooperative arm slide 31 can slide out from the end of the track segment 11 along its length direction to achieve separation.

[0079] exist Figure 17 In the embodiment shown, two sets of second bearings 312 are staggered along the length direction of the mounting plate 311. The length direction of the mounting plate 311 is the same as the length direction of the track segment 11. The distance between the two sets of second bearings 312 along the width direction of the mounting plate 311 is less than the diameter of the second bearings 312, which allows the width dimension of the mounting plate 311 to be reduced, thereby reducing the weight of the cooperative arm slide 31.

[0080] Preferably, at least one set of second bearings 312 are eccentric bearings, by adjusting the center position of the eccentric bearings, the fitting accuracy between the eccentric bearings and the sliding rails 113 on the track section 11 is adjusted, so that the collaborative arm sliding table 31 moves along the length direction of the track more stably.

[0081] Referring to Figure 18 , the mounting plate 311 includes a main body part 3111 and a magnetic attraction part 3112, the main body part 3111 is of aluminum material structure or aluminum alloy material structure, and the second bearings 312 are connected to the main body part 3111. The top surface of the main body part 3111 is provided with a groove, and the magnetic attraction part 3112 is fixed in the groove. The magnetic attraction part 3112 is of magnetic conductive material structure, for example, iron sheet, so that the magnetic attraction part 3112 can be connected with the welding robot 32 by magnetic attraction. Among them, the mounting plate 311 is divided into the main body part 3111 of aluminum material or aluminum alloy material and the magnetic attraction part 3112 of iron material, which is relatively iron material structure, so as to reduce the overall weight of the mounting plate 311. In other embodiments, the main body part 3111 can also be made of other light material materials, and the magnetic attraction part 3112 can be a magnet structure. It should be noted that the main body part 3111 can also not be provided with a groove, and the magnetic attraction part 3112 is fixed to the top surface of the main body part 3111.

[0082] The main body part 3111 is provided with a connecting structure 3113 for detachable connection with the connector 6 on the side close to the wire feeding mechanism 5. The connecting structure 3113 can be a buckle or a clamping groove. The connector 6 is buckled or clamped with the connecting structure 3113, so that the disassembly and assembly are convenient.

[0083] The top surface of the magnetic attraction part 3112 is provided with a first positioning part 31121 for positioning the welding robot 32 and improving the installation position accuracy of the welding robot 32.

[0084] Referring to Figure 16 , the collaborative arm sliding table 31 further includes a roller 313, which is arranged on the main body part 3111 of the mounting plate 311 and abuts against the top surface of the track section 11, thereby improving the position accuracy of the collaborative arm sliding table 31 when moving along the track, and further improving the welding accuracy of the welding robot 32. Among them, the roller 313 is arranged on the outer side of the second bearing 312 along the width direction of the mounting plate 311, so that the positions of the various support points of the mounting plate 311 on the track are closer to the edge of the mounting plate 311, which improves the stability of the mounting plate 311 compared with the structure in which the roller 313 and the second bearing 312 are concentrated in the middle of the mounting plate 311.

[0085] Referring to Figure 19The welding robot 32 comprises a magnetic base 321, a multi-axis robot 322 and a welding gun 323. The magnetic base 321 is a magnet or an electromagnetic structure, and is magnetically fixed to the magnetic part 3112 to achieve detachable connection between the welding robot 32 and the collaborative arm sliding table 31, and the detachable connection is convenient. The multi-axis robot 322 is fixed to the magnetic base 321, and the welding gun 323 is fixed to one end of the multi-axis robot 322 away from the magnetic base 321. The welding end of the welding gun 323 is moved to the welding seam by controlling the multi-axis robot 322, and the welding gun 323 is controlled to achieve welding of the welding seam. The multi-axis robot 322 can be a three-axis, four-axis, five-axis, six-axis or other robot. In other embodiments, the welding robot 32 does not have the magnetic base 321, the magnetic part 3112 is not provided on the mounting plate 311, and the bottom of the multi-axis robot 322 of the welding robot 32 is directly detachably connected to the main body part 3111, for example, clamped, so that the multi-axis robot 322 is fixed to the mounting plate 311.

[0086] The magnetic base 321 is provided with a second positioning part 3211, and the second positioning part 3211 is provided in cooperation with the first positioning part 31121. When the welding robot 32 is installed on the collaborative arm sliding table 31, the second positioning part 3211 cooperates with the first positioning part 31121 to achieve alignment between the welding robot 32 and the collaborative arm sliding table 31, and improve the position accuracy of the welding robot 32. Figure 18 and Figure 19 In the embodiments shown in FIGS. 11 and 12, the first positioning part 31121 protrudes from the top surface of the magnetic part 3112, and the second positioning part 3211 is recessed from the bottom surface of the magnetic base 321. When the magnetic base 321 is placed on the top surface of the magnetic part 3112, the first positioning part 31121 is inserted into the second positioning part 3211 to achieve positioning between the magnetic base 321 and the magnetic part 3112. In other embodiments, the positions of the first positioning part 31121 and the second positioning part 3211 can be interchanged, i.e., the first positioning part 31121 is recessed from the top surface of the magnetic part 3112, and the second positioning part 3211 protrudes from the bottom surface of the magnetic base 321.

[0087] In some embodiments, the welding robot 32 further comprises a camera 324, which is preferably an industrial camera. The camera 324 is arranged on the outside of the welding gun 323, and the camera 324 can identify the position and trajectory of the welding seam. The multi-axis robot 322 drives the welding gun 323 to move according to the position and trajectory of the welding seam obtained by the camera 324, so as to realize automatic welding. Moreover, for some special welding environment, such as welding in a small space, automatic welding by the welding robot 32 makes welding more convenient.

[0088] Referring to Figure 20The driving mechanism 4 comprises a driving motor 41, a gear 42 and a rack 43, the rack 43 is fixed on the track segment 11, and the length direction of the rack 43 is the same as the length direction of the track. The driving motor 41 is fixed on the mounting plate 311, the gear 42 is fixed on the output shaft of the driving motor 41 and is in meshing connection with the rack 43, so that when the driving motor 41 drives the gear 42 to rotate, the cooperative arm sliding table 31 can be driven to move along the length direction of the track. Wherein, the rack 43 is arranged on each track segment 11, when the adjacent two track segments 11 are spliced together, the racks 43 arranged on the adjacent two track segments 11 are also spliced together, so that the cooperative arm sliding table 31 can move along the length direction of the whole guide rail.

[0089] Referring to Figure 15 and Figure 21 The wire feeding mechanism 5 comprises a wire feeding sliding table 51 and a wire feeder 52, the wire feeding sliding table 51 is detachably connected with the track segment 11, so that the wire feeding sliding table 51 can be detached from the track segment 11. The wire feeder 52 is used for feeding welding wire to the welding gun 323, so that the welding gun 323 can continuously perform welding work. The wire feeder 52 is detachably connected with the wire feeding sliding table 51, so that the wire feeder 52 and the wire feeding sliding table 51 can be detached from the track segment 11 respectively. The wire feeder 52 and the wire feeding sliding table 51 can be fixedly connected, so that the wire feeder 52 and the wire feeding sliding table 51 are detached from the track segment 11 together.

[0090] The wire feeding sliding table 51 comprises a mounting bottom plate 511 and a first bearing 512 arranged on the bottom surface of the mounting bottom plate 511, the first bearing 512 is configured with at least three, and the first bearing 512 is divided into two groups along the width direction of the mounting bottom plate 511, the width direction of the mounting bottom plate 511 is the same as the width direction of the track. Figure 21 In the embodiment shown in the figure, each group of first bearings 512 contains two first bearings 512. The circumferential outer surface of the first bearing 512 is formed with a first circular groove, and the first circular grooves of the two groups of first bearings 512 are respectively matched with the sliding rails 113 on the inner walls of the two sides of the track segment 11, so that after the wire feeding sliding table 51 is mounted on the track segment 11, it can only move along the length direction of the track segment 11. When it is necessary to detach the wire feeding sliding table 51 from the track segment 11, the wire feeding sliding table 51 can slide out from the end of the length direction of the track segment 11 to realize separation.

[0091] The two groups of first bearings 512 are arranged in a staggered manner along the length direction of the mounting bottom plate 511, the length direction of the mounting bottom plate 511 is the same as the length direction of the track segment 11, and the distance between the two groups of first bearings 512 along the width direction of the mounting bottom plate 511 is less than the diameter of the first bearing 512, so that the width size of the mounting bottom plate 511 can be reduced, and the weight of the wire feeding sliding table 51 is further reduced.

[0092] Preferably, at least one set of first bearings 512 is an eccentric bearing, and the center position of the eccentric bearing is adjusted to adjust the fitting accuracy between the eccentric bearing and the slide rail 113 on the track section 11, so that the wire feeding slide table 51 is more stable when moving along the length direction of the track.

[0093] The mounting bottom plate 511 is an aluminum material structure or an aluminum alloy material structure, which has the advantage of light weight, so that the overall weight of the mounting bottom plate 511 is lighter, thereby facilitating the staff to carry the wire feeding mechanism 5.

[0094] In Figure 21 In the embodiment shown, the width dimension of the mounting bottom plate 511 is smaller than the width dimension of the wire feeder 52. The support rod 513 is fixed to the top surface of the mounting bottom plate 511, the length direction of the support rod 513 extends along the width direction of the mounting bottom plate 511, and the length direction of the support rod 513 is fixedly connected to the edge of the bottom surface of the wire feeder 52, so that the support points of the mounting bottom plate 511 supporting the wire feeder 52 are distributed at the edges of the wire feeder 52, improving the stability of the wire feeder 52, and the width dimension of the mounting bottom plate 511 can be reduced, reducing the weight of the wire feeding slide table 51.

[0095] Referring to Figure 15 , at least one of the connection between the connector 6 and the welding mechanism 3 and the connection between the connector 6 and the wire feeding mechanism 5 is detachable, so that the welding mechanism 3 and the wire feeding mechanism 5 can be separated to form independent structures, and can be detached from the track, reducing the weight of the individual components when the welding mechanism 3 and the wire feeding mechanism 5 are disassembled, making it easier to carry.

[0096] In Figure 15 the embodiment shown, the connector 6 is fixed to the mounting bottom plate 511, and the connector 6 is connected to the side of the mounting bottom plate 511 close to the welding mechanism 3, so that the distance between the connector 6 and the connecting structure 3113 on the mounting plate 311 is shorter, facilitating the quick connection between the connector 6 and the connecting structure 3113 on the mounting plate 311.

[0097] Referring to Figure 22 , in an embodiment, the connector 6 is a take-up device, the connector 6 includes a housing 61, a winding member 62, and a traction rope 63, the housing 61 is fixedly connected to the wire feeding mechanism 5, the winding member 62 is fixed in the housing 61, one end of the traction rope 63 is fixedly connected to the winding member 62, and the other end of the traction rope 63 extends out of the housing and is buckled to the welding mechanism 3. Therefore, the traction rope 63 and the welding mechanism 3 are connected by buckling, which can be detached and is convenient to disassemble.

[0098] The winding member 62 is a spring, one end of which is fixedly connected to the housing 61, and the other end is a free end, to which one end of the traction rope 63 is connected. When the traction rope 63 is separated from the welding mechanism 3, the traction rope 63 is wound in the housing 61 under the elastic action of the spring. When it is needed to connect the traction rope 63 with the welding mechanism 3, the end of the traction rope 63 away from the winding member 62 is pulled, so that the traction rope 63 extends out of the housing and can be buckled with the welding mechanism 3. After the traction rope 63 is connected with the welding mechanism 3, the winding member 62 is in an energy storage state.

[0099] Since the lengths of the traction rope 63 and the winding member 62 are set, the maximum length of the traction rope 63 extending out of the housing 61 is also fixed. When the driving mechanism 4 drives the welding mechanism 3 to move away from the wire feeding mechanism 5, the welding mechanism 3 pulls the traction rope 63 to extend out of the housing 61, and when the extension length reaches the maximum, the wire feeding mechanism 5 moves with the welding mechanism 3. When the driving mechanism 4 drives the welding mechanism 3 to move towards the wire feeding mechanism 5, the welding mechanism 3 moves to contact the outer surface of the wire feeding mechanism 5, and then pushes the wire feeding mechanism 5 to move together. Before the welding mechanism 3 moves towards the wire feeding mechanism 5 and contacts the outer surface of the wire feeding mechanism 5, the traction rope 63 is automatically wound in the housing 61 under the elastic action of the winding member 62, so as to avoid the traction rope 63 hanging outside the housing 61 and being easily hooked to other objects, thereby affecting the normal work of the welding device 100. In other embodiments, the winding member 62 can also be a motor, and the traction rope 63 is wound on the rotating shaft of the motor through the rotation of the motor.

[0100] In an embodiment, the connector 6 is a snap lock structure. That is, the connector 6 includes a buckle seat and a snap lock piece, one of which is fixed on the welding mechanism 3 and the other of which is fixed on the wire feeding mechanism 5. By buckling the snap lock piece with the buckle seat, the wire feeding mechanism 5 and the welding mechanism 3 are connected together, and the disassembly and assembly are convenient.

[0101] The welding device 100 of the present application comprises a welding track 10 and a welding equipment 30, the welding track 10 comprises a track assembly 1 and a connecting assembly 2, the track assembly 1 comprises a plurality of track segments 11, the plurality of track segments 11 are detachably connected in sequence along the length direction to form a track, so that the welding track 10 can be divided into a plurality of track segments 11, thereby the weight of each track segment 11 is smaller, which is convenient for users to carry. The connecting assembly 2 is arranged on each track segment 11, the connecting assembly 2 comprises a connecting piece 21 and a locking piece 22, the connecting piece 21 is connected to the track segment 11 and can move along the length direction of the track segment 11 to adjust the relative position between the connecting piece 21 and the support structure 200, the locking piece 22 is connected with the connecting piece 21 and the track, and can lock the connecting piece 21 on the track segment 11, the welding device 100 is detachably connected with the support structure 200 through the connecting piece 21, so that the welding device 100 is fixed on the support structure 200, the connection between the connecting assembly 2 and the support structure 200 is realized, and the relative position between the connecting piece 21 and the support structure 200 is adjusted by operating the locking piece 22, so that the connecting piece 21 can be accurately connected with the support structure 200, and the connection is more convenient. In this way, the welding device 100 can be quickly assembled.
