At present, the manufacturing process of steel bar cages mostly adopts manual operation, with low work efficiency. In the actual construction process, the demand for steel bar cages is large, and it is difficult to ensure the on-site supply of steel bar cages by manual production; due to manual operation, there are large human factors and the processing quality is unstable.

[0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies of the prior art. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and the present invention provides an automatic processing method for rectangular beam-column steel bar cages.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions: An automatic processing method for rectangular beam-column steel bar cages, comprising the following steps: Step S1, cutting and processing the longitudinal bars and stirrups according to the dimensions of the steel bar cage; Step S2, placing the fixture system on the stirrup feeding device by an AGV cart, and using the feeding robot to sequentially place the stirrups above the fixture system, so that the stirrups of the steel bar cage are positioned according to preset parameters; Step S3, sequentially placing the longitudinal bars on the single longitudinal bar conveying device through a hoist. The single longitudinal bar conveying device faces the synchronous conveying device. The single longitudinal bar conveying device conveys the single longitudinal bar monomer to the synchronous conveying device. There are corresponding multiple positioning rollers on the pusher of the synchronous conveying device to support the longitudinal bars, so that the longitudinal bars are distributed according to the preset parameters of the steel bar cage; Step S4, transporting the fixture system to the transverse movement mechanism by an AGV cart. The multiple pushers of the assembly and welding device adjust their positions along the ground rail to make way for the transverse movement of the fixture system. After the transverse movement mechanism transversely moves the fixture system above the ground rail, the fixture system is supported by multiple brackets arranged in the middle of the ground rail, and then the multiple pushers of the assembly and welding device are reset to nest on the outer periphery of the fixture system; Step S5, the synchronous conveying device drives the longitudinal bars to be synchronously conveyed to the assembly and welding device close to the pusher of the assembly and welding device. Through the reciprocating transportation of the pusher close to the assembly and welding device until all the longitudinal bars are conveyed to the assembly and welding device, the stirrups and longitudinal bars are assembled into a steel bar cage by the support of the assembly and welding device; Step S6: Weld the stirrups and longitudinal bars between the first and second pusher cars of the assembly and welding device away from the synchronous conveying device by a welding robot. The first pusher car in the direction away from the synchronous conveying device of the assembly and welding device drives the longitudinal bars and the fixture system to move forward synchronously, so as to complete the welding of the steel cage through the welding robot.

[0011] Preferably, the pusher car of the synchronous conveying device close to the assembly and welding device moves back and forth to synchronously push the longitudinal bars to the assembly and welding device. During the forward pushing of the longitudinal bars, the pusher car of the synchronous conveying device clamps the longitudinal bars, and the pusher car of the assembly and welding device releases the longitudinal bars; during the backward movement of the pusher car of the synchronous conveying device close to the assembly and welding device, the pusher car of the synchronous conveying device releases the longitudinal bars, and the pusher car of the assembly and welding device clamps the longitudinal bars, and reciprocates until the pushing of the longitudinal bars is completed.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0021] In view of the problems in the production of steel bar cages in the prior art, the present application provides an automated processing method for rectangular beam-column steel bar cages for manufacturing rectangular steel bar cages. As Figure 1-17 shown, it includes the following steps: Step S1: Cut and process the longitudinal bars 9 and stirrups according to the dimensions of the steel bar cage; Step S2: The production line used for processing the steel bar cage includes a stirrup placing device 1, a single longitudinal bar conveying device 2, a synchronous conveying device 3, and an assembly and welding device 5. The fixture system is placed on the stirrup placing device 1 by an AGV cart. The stirrup placing device 1 is used for placing stirrups. The placing robot is used to sequentially place the stirrups above the fixture system and fix the stirrups at preset intervals and quantities, so that the stirrups of the steel bar cage are positioned according to preset parameters; Step S3: The longitudinal bars 9 are sequentially placed on the single longitudinal bar conveying device 2 by a lifting tool. The single longitudinal bar conveying device 2, the synchronous conveying device 3, and the assembly and welding device 5 are linearly distributed. The single longitudinal bar conveying device 2 faces the synchronous conveying device 3. The synchronous conveying device 3 and the assembly and welding device 5 are slidably assembled on the same ground rail 7. The single longitudinal bar conveying device 2 conveys the longitudinal bar monomers to the synchronous conveying device 3. The pusher cart of the synchronous conveying device 3 is provided with a corresponding plurality of positioning rollers 310 to support the longitudinal bars 9, so that the longitudinal bars 9 are distributed according to the preset parameters of the steel bar cage, so that the synchronous conveying device 3 can push the longitudinal bars 9 to the assembly and welding device 5.

[0022] Step S4: The fixture system is transported to the transverse movement mechanism 8 by an AGV cart. The transverse movement mechanism 8 is located outside the ground rail 7. There are corresponding groups of transverse movement mechanisms 8 for the fixture system outside the ground rail 7. A plurality of transverse movement mechanisms 8 are arranged at different positions corresponding to the assembly and welding device 5. The transverse movement track 801 with telescopic function is provided on the transverse movement mechanism 8. The transverse movement track 801 is driven by a stepping motor or a pneumatic rod. The lower part of the transverse movement track 801 slides with the transverse movement mechanism 8 through a dovetail groove to ensure the supporting ability after extension. The transverse movement track 801 extends into or withdraws from above the ground rail 7 to perform the transverse movement of the fixture system. The pusher carts of the assembly and welding device 5 adjust their positions along the ground rail 7 to make way for the transverse movement of the fixture system. After the transverse movement mechanism 8 transverses the fixture system above the ground rail 7, the fixture system is supported by a plurality of brackets 501 arranged in the middle of the ground rail 7, and then the pusher carts of the assembly and welding device 5 are reset to nest around the fixture system.

[0023] Step S5. The synchronous conveying device 3 includes a pusher cart and a longitudinal bar spacing adjustment mechanism. The pusher cart of the synchronous conveying device 3 close to the assembly and welding device 5 drives the longitudinal bars 9 to be synchronously conveyed to the assembly and welding device 5. Through the reciprocating transportation of the pusher cart close to the assembly and welding device 5 until all the longitudinal bars 9 are conveyed to the assembly and welding device 5, and through the support of the assembly and welding device 5, the stirrups and longitudinal bars 9 are assembled into a steel reinforcement cage.

[0024] Step S6. The welding robot 6 welds the stirrups and longitudinal bars 9 between the first and second pusher carts of the assembly and welding device 5 far from the synchronous conveying device 3; the first pusher cart in the direction where the assembly and welding device 5 is far from the synchronous conveying device 3 drives the longitudinal bars 9 and the fixture system to move forward synchronously. Through external force traction, the fixture system and the longitudinal bars 9 are driven to pass through the welding robot 6 synchronously, and the welding robot 6 is used for welding. A plurality of brackets 501 are evenly distributed at the position of the ground rail 7 corresponding to the assembly and welding device 5 to ensure the displacement of the fixture system during the traction process. The plurality of brackets 501 are evenly distributed in the length direction of the ground rail 7, and thus the steel reinforcement cage welding is completed through the welding robot 6.

[0025] In an alternative embodiment, Step S2 and Step S3 are carried out synchronously.

[0026] In Step S3, the pusher cart includes a bottom frame 305, an upper frame 303, a left frame 304 and a right frame 301, which are respectively used to install four longitudinal bar spacing adjustment mechanisms. Among them, adjustment rails 306 corresponding to the left frame 304 and the right frame 301 are provided on the bottom frame 305 and the upper frame 303, so that the left frame 304 and the right frame 301 can adjust the spacing between the bottom frame 305 and the upper frame 303. Specifically, the left frame 304 and the right frame 301 are independently adjusted by a seventh driver, and the seventh driver can be any one of a stepper motor, an electric lead screw or a cylinder.

[0027] Furthermore, an adjustment plate 307 is provided on the upper frame 303. The adjustment plate 307 is slidably assembled longitudinally on the upper frame 303, and its lower end is correspondingly connected to the corresponding longitudinal bar spacing adjustment mechanism. A rack is provided at the edge of the adjustment plate 307, and the adjustment plate 307 is driven by a stepper motor and a gear provided on the upper frame 303 to adjust the longitudinal bar spacing adjustment mechanism, so as to be applicable to steel reinforcement cages of different models.

[0028] In this embodiment, the number of pusher carts in the synchronous conveying device 3 is 4, and the number of pusher carts in the assembly and welding device 5 is 4 or 5, and one pusher cart far from the synchronous conveying device 3 is used to traction the steel reinforcement cage.

[0029] The assembly and welding device 5 includes a pusher cart, brackets 501, a stirrup alignment mechanism and a welding robot 6. The pusher cart in the assembly and welding device 5 has the same structure as the pusher cart of the synchronous conveying device 3, and longitudinal bar spacing adjustment mechanisms are correspondingly provided.

[0030] Similarly, multiple pushing workshops are distributed at intervals on the ground rail 7. The ground rail 7 is a straight rail. The longitudinal bar spacing adjustment mechanism on the pusher of the assembly and welding device 5 is adjusted to be the same as the spacing of the longitudinal bars 9 of the synchronous conveying device 3, so that the longitudinal bars 9 conveyed by the synchronous conveying device 3 can be received smoothly. Multiple brackets 501 are evenly distributed at the position of the ground rail 7 corresponding to the assembly and welding device 5. The multiple brackets 501 are evenly distributed in the length direction of the ground rail 7. A lifting mechanism is provided below the bracket 501. The lifting mechanism can be the eighth driver 509, specifically a cylinder or a hydraulic cylinder, to lift the fixture system to position the stirrups. Two rollers 508 corresponding to the fixture system are provided on the bracket 501. Specifically, during the process of placing the fixture system, the pusher moves away to make way. After the fixture system moves horizontally, the pusher resets in sequence. During the reset process, when the pusher passes by the bracket 501, the bracket 501 retracts, and the fixture system continues to remain stable under the support of other brackets 501. For positioning, a position sensor corresponding to the pusher is provided on the ground rail 7 to automatically control the lifting of the bracket 501.

[0031] Then, the longitudinal bars 9 are pushed in place by the pusher. During the pushing process, the pusher close to the assembly and welding device 5 moves back and forth until the longitudinal bars 9 are pushed. At this time, the longitudinal bars 9 and the stirrups form a reinforcement cage under the support of the positioning rollers 310 for subsequent welding. A welding robot 6 is provided on one side of the ground rail 7. First, the reinforcement cage between the first and second pushers far from the synchronous conveying device 3 is welded to initially connect the stirrups and the longitudinal bars 9. Then, the pushers far from the synchronous conveying device 3 pull the reinforcement cage through the welding robot 6 for welding.

[0032] In this embodiment, a clamping mechanism 311 corresponding to the longitudinal bars 9 is provided on the positioning rollers 310 to meet the requirements of pushing or pulling. During the pulling process, the fixture system moves synchronously to ensure the relative positions of the longitudinal bars 9 and the stirrups.

[0033] The single longitudinal bar conveying device 2 includes a wire threading frame 201, a conveying rail 202 and conveying wheels 205. The two wire threading frames 201 are distributed oppositely. The height of the wire threading frame 201 is adapted to the height of the synchronous conveying device 3. The two wire threading frames 201 can be slidably assembled along the transverse direction of the steel reinforcement cage respectively, so that the position of the wire threading frame 201 can be adjusted to convey the longitudinal bars 9 at different transverse positions. In order to convey the longitudinal bars 9 in the longitudinal direction, the conveying rail 202 points to the synchronous conveying device 3 and is slidably assembled longitudinally inside the wire threading frame 201, so that the position can be adjusted transversely and longitudinally. Further, the conveying wheels 205 are distributed at intervals in the conveying rail 202. The conveying rail 202 can be a V-shaped groove. At least the conveying wheels 205 are arranged at one end of the conveying rail 202 away from the synchronous conveying device 3 to drive the longitudinal bars 9 to be conveyed to the synchronous conveying device 3. The number of the conveying wheels 205 can be multiple, and the multiple conveying wheels 205 are evenly distributed in the conveying rail 202.

[0034] In an alternative embodiment, the pushing cart is a square truss welded by square steel and has an internal space adapted to the shape of the steel reinforcement cage. A plurality of pushing carts are slidably assembled on the ground rail 7. The pushing carts slide along the ground rail 7. Specifically, traveling wheels are provided at the bottom of the pushing carts, and the traveling wheels are correspondingly connected with driving motors, so that the distance or position can be moved according to actual needs, and multiple longitudinal bars 9 are driven to be synchronously conveyed to the assembling and welding device 5. In this embodiment, the driving motor can be directly connected to the traveling wheels, or a rack is provided on the ground rail 7, the driving motor is arranged at the bottom of the pushing cart, and the pushing cart is driven by the gear meshing with the rack.

[0035] Four longitudinal bar spacing adjusting mechanisms are provided around the pushing cart. The four longitudinal bar spacing adjusting mechanisms respectively correspond to the four sides of the steel reinforcement cage to support the longitudinal bars 9 on each side of the steel reinforcement cage. A plurality of positioning rollers 310 are slidably assembled on the rail plate 302 of the longitudinal bar spacing adjusting mechanism. The positioning rollers 310 are used to support the longitudinal bars 9. The spacing of the longitudinal bars 9 of the steel reinforcement cage can be adjusted according to actual needs by sliding the positioning rollers 310, so as to be applicable to steel reinforcement cages of different models. Adjust the adjusting member 312 on the longitudinal bar spacing adjusting mechanism, and drive the positioning rollers 310 to adjust the spacing of the longitudinal bars 9 through the adjusting member 312.

[0036] In an alternative embodiment, during the pushing process of the longitudinal bars 9, in order to maintain the stability of the stirrups, a stirrup straightening mechanism is provided on the pushing cart. The stirrup straightening mechanism is arranged above the steel reinforcement cage. A plurality of clamps are provided on the stirrup straightening mechanism for clamping and straightening the stirrups to ensure the stability of the stirrups.

When the pushing of the longitudinal bars 9 is completed, the stirrups are loosened for traction.

[0037] In an alternative embodiment, the longitudinal bar spacing adjustment mechanism includes a rail plate 302, an adjusting member 312, a scissor adjuster, and a first driver 309. The rail plate 302 is a rectangular plate, which is fixedly arranged on the pusher cart correspondingly. The rail plates 302 at the bottom can be horizontally distributed to minimize the bottom gap as much as possible and improve the stability of the pusher cart. A plurality of adjusting members 312 are slidably assembled on the rail plate 302. The adjusting member 312 is a strip-shaped plate, and tracks corresponding to the adjusting members 312 are arranged on the rail plate 302. The length of the adjusting member 312 is adapted to the width of the rail plate 302. Positioning rollers 310 are correspondingly connected to the side of the rail plate 302 corresponding to the steel reinforcement cage to support the longitudinal bars 9 of the steel reinforcement cage. The longitudinal bar spacing adjustment mechanism located on the bottom frame 305 can connect the adjusting member 312 and the positioning roller 310 through a support plate, and a V-shaped clamping member is arranged on the micro-push rod located on the bottom frame 305, and the V-shaped clamping member extends above the corresponding positioning roller 310. Two scissor adjusters are distributed in parallel along the length direction of the rail plate 302. Each scissor adjuster includes a plurality of scissor adjustment units 308 hinged to each other. The scissor adjustment unit 308 includes two shear plates in a scissor cross shape. The scissor adjustment units 308 of the two scissor adjusters divide the plurality of adjusting members 312 into a single array group and a double array group in a spaced connection form respectively. Specifically, the adjusting members 312 in the single array group are correspondingly connected to the scissor adjustment units 308 at the relative positions of one scissor adjuster, and the adjusting members 312 in the double array group are correspondingly connected to the scissor adjustment units 308 at the relative positions of the other scissor adjuster. One hinge shaft of the scissor adjustment unit 308 is correspondingly hinged to the adjusting member 312, so that the space can be fully utilized and the length of the hinge rod of the scissor adjustment unit 308 can be reduced.

[0038] The two first drivers 309 can be stepping motors. One end of the scissor adjuster, where the scissor adjustment unit 308 is hinged to the rail plate 302. A rack is connected to one of the hinge shafts of any two adjacent scissor adjustment units 308.

The two first drivers 309 drive the two scissor adjusters respectively to adjust the positions of the adjusting members 312 in the single array group and the double array group respectively. The scissor adjuster is used to adjust the spacing to adapt to the distribution of the longitudinal bars 9 with different spacings.

[0039] In an alternative embodiment, in step S2, centering plates 107 driven by a driving frame 102 are arranged on both sides of the fixture system. The stirrups on the fixture system are aligned with each other by squeezing on both sides through the centering plates 107 and centered relative to the fixture system.

[0040] The stirrup arranging device 1 includes a fixture system and a lateral centering tooling. The lower part of the fixture system is a square truss, whose shape is adapted to the steel reinforcement cage. A plurality of stirrup clamping mechanisms 311 are arranged at intervals on both sides of the fixture system.

Driven by the springs, the lower ends of the clamping plates 109 have a tendency to clamp each other, so as to squeeze both sides of the stirrup through deformation after the stirrup is loaded, thereby maintaining the stability of the stirrup.

[0044] In this embodiment, the length of the clamping plate 109 is adapted to the length of the fixed plate 108. The upper end of the clamping plate 109 extends upward from the fixed plate 108, and an inclined surface is provided on the inner side of the part where the upper end of the clamping plate 109 extends out of the fixed plate 108 to form a V-shaped guiding inlet corresponding to the stirrup, which is convenient for putting in the stirrup. The distance between the two clamping plates 109 in the parallel state is adapted to the thickness of the stirrup. In response to the stirrup being placed in the strip-shaped notch, the two clamping plates 109 are driven to be in a parallel state and clamp the stirrup. In order to reduce the volume of the stirrup clamping mechanism 311, stepped platforms with reduced thickness are provided on the adjacent sides of the lower half of the two clamping plates 109, so that after the stirrup is taken out, the two clamping plates 109 cross in a scissor shape through the stepped platforms, thereby fully maintaining the angle of the upper V-shaped guiding inlet and ensuring the smooth insertion of the stirrup. Preferably, the fixed plate 108 can support more than 3 limbs of the stirrup.

[0045] In an alternative embodiment, the fixture system includes a main beam 105 and a cross beam 104. The main beam 105 is a square steel. The two main beams 105 are parallelly distributed for installing the stirrup clamping mechanism 311. A plurality of cross beams 104 are evenly distributed between the two main beams 105, forming a square planar truss therefrom. The cross beam 104 includes two mutually sleeved sleeves. Locking bolts are correspondingly provided on the outer sleeve, so that the width of the fixture system can be adjusted according to actual needs to be applicable to different models of square steel cages.

[0046] In an alternative embodiment, bases 101 are respectively provided on both sides of the fixture system. The bases 101 are trusses welded by square steels. A plurality of evenly distributed third slide rails 106 pointing to the fixture system are provided on the bases 101. The driving frame 102 is slidably assembled on the third slide rails 106 and is driven by a fifth driver. The fifth driver can be an electromagnetic push rod, a cylinder or a hydraulic cylinder, which is specifically selected according to actual situations; a guide roller is provided on one side of the base 101 close to the fixture system. The guide rollers respectively support the stirrup to prevent the stirrup from losing stability during the centering process. A longitudinally extending limiting groove corresponding to the stirrup is provided on the centering plate 107. Two centering plates 107 on the same side can be provided.

[0047] In an alternative embodiment, the stirrup straightening mechanism is disposed between two adjacent pusher cars of the assembly welding device 5, and includes a support beam 502 and clamping jaws 504. One end of the support beam 502 is connected above one of the pusher cars and extends along the center line of the pusher car. Two sets of clamping jaws 504 are respectively located on the assembly plate 503 by sliding assembly through the main shafts 505. The assembly plate 503 is assembled below the support beam 502 through a lifting mechanism. The lifting mechanism includes at least two sixth drivers 507. The sixth driver 507 can be an electromagnetic push rod or a cylinder and can be selected according to actual requirements to achieve longitudinal adjustment of the stirrup straightening mechanism. After the longitudinal bars 9 are pushed, the stirrup straightening mechanism releases the stirrups. The number and spacing of the clamping jaws 504 are adapted to the stirrups at the corresponding positions. The clamping jaws 504 on the two main shafts 505 are staggered. The two main shafts 505 are respectively driven by two pull rods 506 to clamp the stirrups. The pull rod 506 can be a cylinder or an electromagnetic push rod. Mounting plates corresponding to the two main shafts 505 are provided on the assembly plate 503, and the main shafts 505 are slidably assembled on the mounting plates.

[0048] Furthermore, the two sets of clamping jaws 504 are linearly distributed, and the first main shaft and the second main shaft are parallelly distributed. Among them, the odd-numbered clamping jaws 504 are slidably assembled on the first main shaft and are correspondingly connected and driven through the first main shaft; the even-numbered clamping jaws 504 are slidably assembled on the second main shaft and are correspondingly connected and driven through the second main shaft, so that the odd-numbered clamping jaws 504 and the even-numbered clamping jaws 504 are independently driven by the two main shafts 505 respectively, and they move relatively to clamp the stirrups.

[0049] In order to push the longitudinal bars 9, a clamping mechanism 311 corresponding to the longitudinal bars 9 is provided on the longitudinal bar spacing adjusting mechanism. The clamping mechanism 311 can be a micro push rod provided on the adjusting member 312. The micro push rod can be any one of an electromagnetic push rod, a pneumatic rod, and an oil cylinder. The driving end of the micro push rod points to the positioning roller 310, so that the longitudinal bars 9 of the steel reinforcement cage can be clamped together with the positioning roller 310.

[0050] Furthermore, the longitudinal bars 9 can be pushed in the following manner. First, the four pusher cars move towards the assembly welding device 5 as a whole until they overlap in front of the assembly welding device 5. Then, the pusher cars of the assembly welding device 5 clamp the longitudinal bars 9. The synchronous conveying device 3 retracts and continuously pushes the longitudinal bars 9 through the reciprocating movement of the pusher car close to the assembly welding device 5. During the clamping and pushing process of the synchronous conveying device 3, the assembly welding device 5 releases the clamping of the longitudinal bars 9. During the process that the pusher car of the synchronous conveying device 3 releases the longitudinal bars 9 and retracts, the assembly welding device 5 clamps the longitudinal bars 9 until the synchronous conveying device 3 resets after the longitudinal bars 9 are completely pushed. At this time, the assembly welding device 5 clamps the longitudinal bars 9 for welding and integrally pulls the fixture system and the longitudinal bars 9 under the clamping of the pusher car.

[0051] Alternatively, the synchronous conveying device 3 reciprocates near the pusher car of the assembly and welding device 5 to synchronously push the longitudinal bars 9 to the assembly and welding device 5. During the forward pushing process of the longitudinal bars 9, the pusher car of the synchronous conveying device 3 clamps the longitudinal bars 9, and the pusher car of the assembly and welding device 5 releases the longitudinal bars 9; during the backward movement of the pusher car of the synchronous conveying device 3 near the assembly and welding device 5, the pusher car of the synchronous conveying device 3 releases the longitudinal bars 9, and the pusher car of the assembly and welding device 5 clamps the longitudinal bars 9, and this reciprocating movement continues until the pushing of the longitudinal bars 9 is completed.

[0052] In an alternative embodiment, a plurality of brackets 501 are evenly distributed in the length direction of the ground rail 7. A lifting mechanism is provided below the brackets 501, and position sensors corresponding to each bracket 501 are provided on the ground rail 7 to sense the position of the pusher car during the reset process, so as to lower and make way through the lifting mechanism when the pusher car passes by.

[0053] In an alternative embodiment, after the steel cage is welded, the pusher car traction fixture system moves along the position of the ground rail 7 to the lifting station. At this time, the steel cage is transferred by the lifting tool, and the transverse movement mechanism 8 transfers the fixture system to the AGV cart. The AGV cart transports the fixture system to the stirrup feeding device 1 for the production of the next steel cage. A gap corresponding to the AGV cart is provided between the two bases 101 of the stirrup feeding device 1, and a ejector rod corresponding to the fixture system is provided on the AGV cart, so that the fixture system is placed at the designated position by lifting or lowering. A plurality of stirrup buffer zone brackets 4 are provided between the stirrup feeding device 1 and the ground rail 7 for supporting the fixture system after the stirrups are installed.

[0054] In an alternative embodiment, two welding robots 6 are provided on each surface of the steel cage. The two welding robots 6 on the same surface respectively perform the welding of the corresponding half of the steel bar joints. The traveling route of the welding robot 6 is in an S shape, and the welding joints are welded at intervals.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of the claims of the present invention awaiting approval.
