Description

Technical Field

[0001] This invention belongs to the field of automatic welding equipment, specifically an automatic welding device for steel grating processing. Background Technology

[0002] Steel grating is formed by interlocking and welding grooved load-bearing steel plates and transverse round bars. It is widely used in municipal trench covers, platform walkways, chemical plant area protection and other scenarios. The interlocking precision, weld formation quality and grid spacing consistency of the product directly determine the overall load-bearing capacity and safety of the steel grating. At present, steel grating production and processing mostly adopt segmented equipment or semi-manual assembly and welding mode. There are many inherent technical defects in workpiece loading and reversing, steel plate and round bar interlocking positioning, bevel pretreatment and flexible adjustment of grid spacing. It is difficult to meet the needs of large-scale, multi-specification steel grating automated production. Therefore, there is an urgent need for a processing and production equipment that can automatically assemble and weld steel grating.

[0003] For example, Chinese Patent Publication No. CN220161631U discloses an automatic welding device for steel grating, including a robotic arm and a welding torch mounted on the robotic arm. It also includes: a welding base plate located on one side of the robotic arm; a side plate positioning device mounted on the welding base plate for positioning the side plates of the steel grating; several support plate positioning devices mounted on the welding base plate for positioning support plates; and several support rod pressing devices mounted on the welding base plate for pressing support rods onto the support plates. This automatic welding device for steel grating uses a robotic arm for automatic welding and achieves the positioning and clamping of the steel grating through the side plate positioning device, support plate positioning device, and support rod positioning device. This makes the positioning and clamping of the steel grating more convenient, shortens the workpiece clamping time, and aims to improve overall welding efficiency and reduce welding costs.

[0004] However, the above solution still has the following drawbacks: 1. The above-mentioned equipment has a low degree of automation integration. The arrangement and splicing of steel plates and round rods mostly rely on manual labor. In conventional production lines, steel plates are mostly fed vertically, which is difficult to directly connect with the horizontal discharge process of the previous leveling and shearing processes. During the transfer of workpieces, manual handling, flipping and straightening are required. Moreover, the alignment deviation between steel plates and round rods is large, which can easily lead to problems such as incomplete engagement and misalignment. After subsequent welding, the consistency of the products is poor, and it is difficult to improve production efficiency.

[0005] 2. After the steel plate is sheared and grooved, burrs and flash are easily generated on the edges of the steel plate and at the groove openings. Most existing welding equipment does not have an in-station online grinding and finishing mechanism. The burrs and flash after the steel plate is grooved are directly carried into the assembly and welding process. The burrs will interfere with the fit and engagement between the groove of the steel plate and the round rod, resulting in a large assembly gap. During welding, it is easy to produce welding defects such as incomplete welds and slag inclusions. At the same time, sharp burrs will also increase the risk of workpiece jamming during assembly and will also result in poor appearance quality of the finished steel grating. Subsequent manual grinding processes are required, increasing production time and manufacturing costs.

[0006] 3. Traditional steel grating welding fixtures mostly use fixed assembly structures for their round rod positioning jaws and steel plate positioning mechanisms. The spacing between the jaws is determined at the factory, which can only produce steel grating products with fixed grid spacing. Moreover, most existing mechanisms can only support the processing of uniformly spaced grids and cannot easily realize the grid arrangement of non-uniform spacing. The processing freedom is low, making it difficult to adapt to the production needs of customized and irregularly shaped steel gratings. The applicable scenarios of the equipment are greatly limited. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of automatically assembling and splicing round rods and steel plates using modular components. This, combined with mesh welding components, enables automated welding. The steel plates are fed horizontally and then flipped and erected, seamlessly connecting to previous workflows. This effectively saves manpower and significantly improves production efficiency while ensuring product quality and consistency. The adjustable lifting seat allows the clamping plate to be lowered from its normal welding position during the plate flipping process. Once the clamping plate and the abutment bar stably hold the erected steel plate, a lifting cylinder is controlled to raise the clamping plate, ensuring stable engagement between the grooves on the steel plate and the round rod. This further enhances the stability of the product processing. To ensure accuracy and precision, the grinding wheel allows for the grinding and finishing of the grooved edges of the steel plate during its transport by the second conveyor belt. This effectively removes burrs and flash from the edges and grooves, ensuring smooth subsequent processing and further improving product quality. Furthermore, the adjustable clamping jaws fixed to the slide rails, along with the adjustable displacement of the connecting block and connecting rod, allow for free adjustment of the spacing between the clamping jaws to regulate the actual spacing between the round rods. Additionally, adjusting the extension distance of the translation cylinder adjusts the actual spacing between the steel plates. Moreover, if specific requirements exist, the spacing can be adjusted to be non-uniform, significantly increasing processing freedom and making the product applicable to unrestricted scenarios.

[0012] Furthermore, the mesh welding component includes a first straight module, which is arranged on the first gantry along the length of the steel plate. A laser welding head is provided on the movable end of the first straight module. The working end of the laser welding head points towards and is close to the intersection of the round rod and the steel plate. A threading device is fixedly connected to the first upright plate at the corresponding position of each round rod. The end of each threading device near the transverse sliding seat is expanded in a trumpet shape, and each round rod passes through the center of the corresponding threading device.

[0013] Furthermore, an extension base is fixedly connected to one side of the lifting seat on the cabinet, and a second upright plate corresponding to the position of the first upright plate is fixedly connected to the extension base. A second conveyor belt assembly for conveying steel plates is provided on one side of the second upright plate, and a third motor is provided on the second upright plate. A third synchronous belt assembly is driven between the power output end of the third motor and the wheel axle of the second conveyor belt assembly. The grooved edge of the steel plate extends beyond the edge of the second conveyor belt assembly.

[0018] In summary, compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting up combined components, the round rod and steel plate are automatically combined and spliced, and the mesh welding components are used to realize automated welding work. The steel plate is selected to be conveyed horizontally in the feeding direction, and then the steel plate is flipped and erected, which can connect the previous workflow, effectively save manpower and greatly improve production and processing efficiency, while ensuring the processing quality and consistency of the product.

[0019] (2) By setting up a lifting seat that can be raised and lowered, when the clamping plate drives the steel plate to flip, the clamping plate is lower than the normal welding position, and the clamping plate performs the normal flipping and erection action. After the clamping plate and the abutment bar stably clamp the erected steel plate, the lifting cylinder is controlled to drive the clamping plate to rise so that the groove on the steel plate and the round rod stably engage, thereby improving the stability and accuracy of the product processing process.

[0020] (3) By setting up a grinding wheel, the edge of the steel plate with grooves can be ground and repaired during the process of the steel plate being transported by the second conveyor belt group, thereby effectively removing the burrs and flashes on the edge of the steel plate and the groove, ensuring the smooth progress of subsequent processing, and further improving product quality.

[0021] (4) By setting the fixed jaws to be adjustable and fixed on the slide rail, and the fixed connection displacement of the connecting block and the connecting rod can also be adjusted, the spacing between each fixed jaw can be freely adjusted according to actual needs to adjust the actual spacing between each round rod. At the same time, the actual spacing between each steel plate can be adjusted by adjusting the extension distance of the translation cylinder. Furthermore, if the product has special requirements, the spacing can also be adjusted to a non-uniform manner, which greatly improves the processing freedom and makes the applicable scenarios unrestricted.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1: like Figure 1-10As shown, an automatic welding device for steel grating processing includes a cabinet 10, a lifting seat 11 on the cabinet 10, a first upright plate 12 fixedly connected to the lifting seat 11, multiple sets of first conveyor belt groups 13 on one side of the first upright plate 12, a first motor 17 fixedly connected to one side of the first upright plate 12, a first synchronous belt group 18 drivingly connected between the power output end of the first motor 17 and the wheel axle of each set of first conveyor belt groups 13, a clamping plate 15 hinged to the surface of the first upright plate 12 at the interval between each set of first conveyor belt groups 13, a clamping plate cylinder 16 hinged between the bottom side of the clamping plate 15 and the lifting seat 11, the first conveyor belt group 13 is used to convey steel plate b for loading, and a vertical lifting cylinder 28 is provided on the cabinet 10 at the corresponding position of the lifting seat 11, the extended end of the lifting cylinder 28 is fixedly connected to the bottom of the lifting seat 11.

[0036] like Figure 1-10 As shown, a horizontal sliding seat 21 is slidably connected to the cabinet 10 on one side of the lifting seat 11. Each horizontal sliding seat 21 is provided with multiple sets of fixed grippers 23 and movable grippers 24 for conveying the round rod a. A translation cylinder 29 is provided on the cabinet 10 at the corresponding position of the horizontal sliding seat 21. The extended end of the translation cylinder 29 is fixedly connected to the horizontal sliding seat 21. The translation cylinder 29 can drive the horizontal sliding seat 21 to move closer to or away from the first vertical plate 12. A first linear module 35 is provided above the first vertical plate 12 along the length direction of the steel plate b. A laser welding head 36 is provided at the movable end of the first linear module 35. The working end of the laser welding head 36 points to the overlapping position of the round rod a and the steel plate b.

[0037] By setting up the first conveyor belt group 13, the steel plate b can be automatically conveyed to the designated position. Then, the flat steel plate b can be flipped upward and erected by the clamping plate 15. At the same time, the round rod a is conveyed by the fixed clamping claw 23 and the moving clamping claw 24, so that the round rod a and the steel plate b overlap and interweave. Then, the laser welding head 36 moves to each overlapping position of the round rod a and the steel plate b in sequence to weld and fix them. After the welding of the steel plate b is completed, the round rod a continues to move forward to make room for the next steel plate b and repeat the above actions. This can realize the automatic welding of the internal mesh of the mesh plate, effectively save manpower and greatly improve the production and processing efficiency, while ensuring the processing quality and consistency of the product.

[0038] The lifting cylinder 28 enables the lifting seat 11 and its components to move up and down within a controllable range. In actual production, grooves are provided on the steel plate b at the corresponding positions of each round rod a to accommodate the rod a. During the flipping of the steel plate b by the clamping plate 15, the grooves and the round rods a are difficult to effectively engage, or the position of the steel plate b may shift, affecting the processing effect. By setting the lifting seat 11 to be able to move up and down, when the clamping plate 15 drives the steel plate b to flip, the clamping plate 15 is lower than the normal welding position, and the clamping plate 15 performs the normal flipping and erecting action. After the clamping plate 15 and the abutment bar 30 stably clamp the erected steel plate b, the lifting cylinder 28 is controlled to drive the clamping plate 15 to rise, so that the grooves on the steel plate b and the round rods a stably engage, thereby improving the stability and accuracy of the product processing.

[0039] During the feeding process of steel plate b, since steel plate b is relatively flat, in actual production and processing, factories are accustomed to stacking steel plate b horizontally rather than directly vertically. In order to connect with the previous processing flow of the factory, this application selects to transport steel plate b horizontally in the feeding direction, and then flips and stands steel plate b vertically. This not only connects with the previous process flow, but also ensures the stability and accuracy of transporting steel plate b horizontally.

[0040] like Figure 1-10 As shown, auxiliary rollers 14 are rotatably mounted on the first vertical plate 12 at both sides of each clamping plate 15. The first conveyor belt group 13, the auxiliary rollers 14, and the upper surface of the clamping plate 15 are on the same plane. An abutment strip 30 is provided on one side of the first conveyor belt group 13 on the first vertical plate 12. A baffle 19 is fixedly connected to the first vertical plate 12 at the conveying end of the first conveyor belt group 13. A first motor 17 is fixedly mounted on the first vertical plate 12. The power output end of the first motor 17 and each group of the first conveyor belt group 13... A first synchronous belt group 18 is connected between the wheel and axle for transmission. A slide rail 22 perpendicular to the length direction of the round rod a is provided on the transverse shift seat 21. Each fixed gripper 23 is fixedly fixed on the slide rail 22 in an adjustable position. Each movable gripper 24 is slidably connected to the slide rail 22. A connecting block 25 is fixedly provided on one side of each movable gripper 24. A connecting rod 26 is fixedly connected between each connecting block 25. A gripper cylinder 27 is fixedly connected to one side of the transverse shift seat 21. The extended end of the gripper cylinder 27 is fixedly connected to one end of the connecting rod 26.

[0041] By setting up auxiliary roller 14 to fill the gap between the first conveyor belt group 13 and the clamping plate 15, it plays an auxiliary role in conveying the steel plate b, avoiding the problem that the steel plate b cannot smoothly transition to the surface of the clamping plate 15 during the process of the first conveyor belt group 13 conveying the steel plate b, which would cause difficulties in feeding. By setting up baffle 19, the final position of the steel plate b can be limited, avoiding the first conveyor belt group 13 from not conveying the steel plate b to the designated position or conveying it beyond the designated position, ensuring the accuracy of the welding processing position of the steel plate b, thereby improving the processing quality and efficiency.

[0042] In actual production, the mesh spacing of the grating needs to be adjusted according to product requirements. If the processing equipment can only meet the processing requirements of one size, it will result in poor applicability and make it difficult to be used in actual processing and production, causing indirect economic losses to the manufacturer.

[0043] By setting the fixed gripper 23 to be adjustablely fixed on the slide rail 22, and the fixed connection displacement of the connecting block 25 and the connecting rod 26 can also be adjusted, the distance between each fixed gripper 23 can be freely adjusted according to actual needs to adjust the actual distance between each round rod a. At the same time, the actual distance between each steel plate b can be adjusted by adjusting the extension distance of the translation cylinder 29. Furthermore, if the product has special requirements, the distance can also be adjusted to be uneven, which greatly improves the degree of processing freedom and makes the applicable scenarios unrestricted.

[0044] like Figure 1-10 As shown, a fixed cutter 31 is fixedly connected to the cabinet 10 between the lifting seat 11 and the horizontal moving seat 21. A first gantry 34 is set on the cabinet 10 at the corresponding position of the fixed cutter 31. A movable cutter 32 is vertically slidably connected to the first gantry 34. A set of cutting hydraulic cylinders 33 is set on the top of the first gantry 34. The extended end of the cutting hydraulic cylinder 33 is fixedly connected to the top of the movable cutter 32. A first linear module 35 is fixedly connected to the first gantry 34. A threader 20 is fixedly connected to the first vertical plate 12 at the corresponding position of each round rod a. The end of each threader 20 near the horizontal moving seat 21 is flared out, and each round rod a passes through the center of the corresponding threader 20.

[0045] By setting a fixed cutter 31 and a moving cutter 32, after the round rod a and the steel plate b are processed to form a grid of a certain length, the moving cutter 32 is driven by the splitting hydraulic cylinder 33 to cooperate with the fixed cutter 31 to cut the round rod a, thereby cutting the grid of a specified length to meet the size requirements of different steel gratings, and further improving the automation level of the equipment and the processing efficiency.

[0046] After the round rod a is cut, the end of the round rod a is no longer restricted. When the fixed gripper 23 and the moving gripper 24 continue to push the round rod a, the position of the round rod a is easily offset, making it difficult for the round rod a to be aligned with the groove on the steel plate b. Therefore, by setting the guide 20, the round rod a is guided and positioned at a rear position near the steel plate b, ensuring that the relative position between the round rod a and the steel plate b is always stable and accurate. At the same time, the end of the guide 20 is set in a trumpet shape to guide the end of the cut round rod a into the guide 20.

[0047] like Figure 1-10 As shown, a transfer platform 37 is provided on one side of the lifting seat 11 on the cabinet 10. Multiple toothed plates 38 perpendicular to the length direction of the steel plate b are slidably arranged in the transfer platform 37. Multiple bearing seats 40 are fixedly connected to the cabinet 10 below the transfer platform 37. A crankshaft 39 is rotatably arranged in each bearing seat 40. The eccentric end of each crankshaft 39 is hinged to the bottom of the corresponding toothed plate 38. A second synchronous belt group 41 is connected between two sets of parallel crankshafts 39. A second motor 42 is provided on the cabinet 10 at the position corresponding to one set of crankshafts 39. The power output end of the second motor 42 is connected to the end of the second vertical plate 49.

[0048] By setting up a transfer platform 37 to support and lift the already welded mesh portion, the finished mesh portion is prevented from sagging or swaying, which could cause the round rod a to bend and wobble, affecting the stability of subsequent welding processes. By setting up a toothed plate 38 and using a crankshaft 39 to drive the toothed plate 38 to creep, the teeth of the toothed plate 38 are used to restrict the bottom edge of the steel plate b and advance the mesh grid by grid. This achieves the cooperation of the fixed gripper 23 and the moving gripper 24 to transport the mesh forward, thereby sharing the resistance encountered by the fixed gripper 23 and the moving gripper 24 when pushing the round rod a. This avoids the problem of inaccurate pushing distance caused by slippage of the clamping position when the fixed gripper 23 and the moving gripper 24 push the round rod a, which would affect the processing dimensions and processing quality.

[0049] like Figure 1-10 As shown, an extension base 48 is fixedly connected to the cabinet 10 at one side of the lifting seat 11. A second upright plate 49 corresponding to the position of the first upright plate 12 is fixedly connected to the extension base 48. A second conveyor belt group 50 for conveying steel plate b is provided on one side of the second upright plate 49. A third motor 58 is provided on the second upright plate 49. A third synchronous belt group 57 is connected between the power output end of the third motor 58 and the wheel axle of the second conveyor belt group 50. The edge of the steel plate b with the groove extends beyond the edge of the second conveyor belt group 50. A grinding wheel seat 59 is provided on the extension base 48 at one side of the second conveyor belt group 50. A fourth motor 60 is provided on the grinding wheel seat 59. A grinding wheel 61 is connected to the power output end of the fourth motor 60. In this embodiment, the grinding wheel 61 is preferably a wire wheel.

[0050] By setting up a second conveyor belt group 50, the steel plate b to be welded can be pre-loaded during the process of conveying, flipping and waiting for welding of the steel plate b within the range of the first conveyor belt group 13.

[0051] In actual production, the pre-processing of steel plate b is mostly stamping and mechanical cutting, which easily leaves burrs and flash on its edges. In particular, the burrs remaining in the grooves of steel plate b can make it difficult for the round rod a to smoothly enter the grooves of steel plate b, negatively impacting the product processing and the quality of the final product. By setting up the grinding wheel 61, the grooved edge of the steel plate b can be ground and trimmed during the process of the steel plate b being conveyed by the second conveyor belt group 50, thereby effectively removing burrs and flash from the edge and groove of the steel plate b, ensuring the smooth progress of subsequent processing, and further improving product quality.

[0052] like Figure 1-10 As shown, two grooves 52 are provided on the second vertical plate 49 above the second conveyor belt group 50. A slider 53 is slidably connected in each groove 52. The two sliders 53 are provided with pressing belt groups 51 opposite to the second conveyor belt group 50. A fastener 56 is fixedly connected to the opening of each groove 52. A plug rod 54 is fixedly connected to each slider 53 and slidably connected. A spring 55 is provided between each fastener 56 and the slider 53 and surrounds the outside of the plug rod 54.

[0053] By setting up the pressing belt group 51, the elastic thrust of the spring 55 can be used in conjunction with the second conveyor belt group 50 to stably clamp the steel plate b, preventing the steel plate b from shifting off the second conveyor belt group 50 or even falling off during the grinding and trimming process of the grinding wheel 61.

[0054] like Figure 1-10 As shown, a straightening plate 43 is provided on the cabinet 10 at the position corresponding to each round rod a. A set of straightening wheels 44 are staggered on each straightening plate 43. A guide wheel 45 is rotatably provided on the straightening plate 43. A bracket 47 is provided inside the cabinet 10 at the position corresponding to the straightening plate 43. Multiple material wheels 46 for storing round rods a are rotatably provided on the bracket 47. The round rod a on each material wheel 46 passes around the corresponding guide wheel 45 and passes between the straightening wheels 44.

[0055] In actual production, the round rod a is usually stored in a coil. However, when the round rod a is released directly after being coiled, it is bent and deformed, making it difficult to use directly. Therefore, by setting a straightening wheel 44, the round rod a is straightened before welding, ensuring that the round rod a is in a straight state during welding, improving product quality, saving the processing steps of pre-processing the round rod a, and improving the degree of automation and processing efficiency.

[0056] In this application, initially, the operator connects the device to the power supply and control system, and at the same time connects the pre-processing and conveying device of steel plate b at the second conveyor belt group 50 to facilitate the automatic feeding of steel plate b. At the same time, the operator places the material wheel 46 on the bracket 47, pulls out each round rod a through the cabinet 10 and around the guide wheel 45, so that the round rod a passes between each group of straightening wheels 44 and through each group of fixed gripper 23 and moving gripper 24, and finally passes into the corresponding threader 20 to complete the preparation action.

[0057] During operation, the second conveyor belt group 50 pre-conveys the steel plate b to the first conveyor belt group 13. During the conveying process, the pressing belt group 51 presses down on the steel plate b and cooperates with the pressing belt group 51 to convey the steel plate b. At the same time, the fourth motor 60 drives the grinding wheel 61 to rotate at high speed to grind and trim the grooved edge of the steel plate b until the entire steel plate b has been ground by the grinding wheel 61. At this time, the steel plate b has entered the conveying range of the first conveyor belt group 13.

[0058] When steel plate b enters the conveying range of the first conveyor belt group 13, clamping plate 15 is in a horizontal state. The first motor 17 drives all the first conveyor belt groups 13 to operate through the first synchronous belt group 18. The first conveyor belt group 13 conveys steel plate b to baffle 19 until the end of clamping plate 15 abuts against baffle 19. At this time, the first motor 17 is turned off and clamping plate cylinder 16 is started, so that clamping plate 15 lifts steel plate b and flips it upward to stand upright. At this time, clamping plate 15 and abutting strip 30 together clamp the bottom of clamping plate 15.

[0059] Then, the control system controls the lifting cylinder 28 to extend outward, pushing each moving jaw 24 to cooperate with the fixed jaw 23 to stably clamp the round rod a. Then, the translation cylinder 29 pushes the round rod a forward until it reaches the specified distance and then stops conveying the round rod a. Subsequently, the lifting cylinder 28 works to push the lifting seat 11 upward, so the steel plate b gradually approaches the round rod a from the bottom until the round rod a enters the grooves on the steel plate b, so that the round rod a and the steel plate b are accurately combined.

[0060] Then, the control system controls the first linear module 35 to drive the laser welding head 36 to move to the overlapping and intersecting positions of the steel plate b and the round rod a to perform welding work, stably welding the steel plate b to each round rod a. After welding is completed, the control gripper cylinder 27 retracts, which controls the moving gripper 24 to open. The translation cylinder 29 drives the transverse seat 21 to retract a specified distance, and then controls the gripper cylinder 27 again to make the fixed gripper 23 and the moving gripper 24 clamp the round rod a. Then, the control plate 15 is reset to return to the horizontal state. At the same time, the translation cylinder 29 is pushed forward again, and the welded steel plate b will move forward with the round rod a and detach from the first conveyor belt group 13. Then, the lifting seat 11 falls down to make the first conveyor belt group 13 correspond to the second conveyor belt group 50, and continue the feeding action of the steel plate b, sending the new steel plate b onto the first conveyor belt group 13 to wait for processing.

[0061] Repeat the above steps to continuously process the steel grating until the internal grid structure is formed.

[0062] As the grid structure gradually forms, the grid enters the range of the support 47, and the second motor 42, in conjunction with the pushing action of the translation cylinder 29, drives the crankshaft 39 to rotate, thereby causing the extension base 48 to periodically undulate. The teeth of the extension base 48 bite and push the bottom edge of the steel plate b grid by grid until the grid plate accumulates a certain length on the support 47.

[0063] Then, when the product reaches the specified design length, the control system directly controls the slitting hydraulic cylinder 33 to push the moving cutter 32 down to cut the round rod a at the specified length. The mesh structure on the bracket 47 is then completed. After that, the moving cutter 32 resets, and the round rod a and steel plate b continue to be loaded, unloaded and assembled to continue subsequent processing and production, achieving continuous production.

[0064] Example 2: like Figure 11 As shown, a welding platform 64 is provided on one side of the transfer station 37 on the rack 10. A frame welding component is provided on the rack 10 at the corresponding position of the welding platform 64. A second gantry 62 is provided on the rack 10 at the corresponding position of the transfer station 37 and the welding platform 64. A handling module 63 is provided on the second gantry 62.

[0065] This application mainly addresses the automatic welding processing of the internal mesh structure of steel grating. Subsequently, by setting up a second gantry 62 and a transport module 63, the processed mesh can be directly transferred to the welding platform 64, and the mesh edges can be welded at the welding platform 64, further improving the expandability of the equipment and realizing the complete welding processing of steel grating.

[0066] The aforementioned laser welding head 36 and handling module 63 are mature existing technologies, and will not be described in detail here.
