Description

Technical Field

[0001] This invention belongs to the field of irradiation breeding device production technology, specifically relating to an automated welding system and method for a uniform irradiation processing cylinder. Background Technology

[0002] Radiation-induced mutation breeding is an important technique in modern agricultural breeding. By irradiating seeds with radiation to induce gene mutations, it is possible to quickly obtain superior mutant germplasm. It has the advantages of short breeding cycles and a rich variety of mutations, and is widely used in the improvement of various crop varieties such as grains, vegetables, and flowers. The irradiation processing cylinder is the equipment that carries the seed irradiation treatment, and its irradiation uniformity directly determines the overall effect of seed mutation breeding.

[0003] Currently, most commercially available seed irradiation processing cylinders are fixed cylinder structures, with seeds statically piled inside. During irradiation, the angle and distance of radiation are fixed, easily leading to problems such as excessively high irradiation doses in the central area, insufficient irradiation doses in the peripheral areas, and almost no irradiation at the bottom, resulting in significant differences in radiation doses between individual seeds within a batch. This uneven irradiation problem causes several breeding drawbacks: First, the seed mutation rate is uneven; some seeds undergoing excessive irradiation develop lethal or malformed mutations, while others, due to insufficient irradiation, fail to produce effective mutations, significantly increasing the workload and difficulty of subsequent germplasm screening. Second, superior mutant germplasm is easily lost; some seeds with high mutation potential fail to undergo effective mutations due to insufficient irradiation doses, or lose activity due to localized over-irradiation, and are mistakenly eliminated during manual screening, resulting in a waste of high-quality germplasm resources. Third, breeding experiments have poor repeatability; inconsistent seed irradiation states between batches lead to significant deviations in breeding experimental data, seriously affecting the scientific rigor and accuracy of radiation breeding research.

[0004] Current irradiation equipment cannot achieve uniform irradiation of seeds from all directions without blind spots, and the shaking process easily causes seed accumulation and displacement, leaving irradiation blind zones. This fails to fundamentally solve the problem of uneven seed irradiation and cannot meet the needs of large-scale production and research in seed mutation breeding. To address this, our company has designed a combined irradiation uniformity processing cylinder, mainly composed of an inner cylinder component, a spiral pusher blade, an outer cylinder component, an outer support frame, an irradiation rotary actuator, inner support rods, and a support plate. Through a double-layer cylinder combined with a spiral pusher structure, it achieves dynamic flipping irradiation of a single layer of seeds, completely eliminating irradiation blind zones and ensuring excellent irradiation uniformity. However, existing technologies lack an automated welding system capable of meeting the welding and assembly requirements of this combined irradiation processing cylinder.

[0005] In view of this, the inventors aim to provide an automated welding system and method for irradiation uniform processing cylinders, to realize automated welding of combined processing cylinders, and to ensure the assembly accuracy and operational stability of the equipment. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and to provide an automated welding system and method for a uniform irradiation processing cylinder.

[0007] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: This invention provides an automated welding system for a uniform irradiation processing cylinder, comprising a docking drive assembly, an internal welding assembly, and an external welding assembly, wherein the internal welding assembly is disposed in the area between the docking drive assembly and the external welding assembly; The combined irradiation processing cylinder to be processed consists of an inner cylinder component, a spiral pusher blade, an outer cylinder component, an outer support frame, an irradiation rotary drive, inner support rods, and a support plate. The spiral pusher blade is snapped onto the outer side of the inner cylinder component. The outer cylinder component is sleeved on the outer side of both the inner cylinder component and the spiral pusher blade. The outer support frame is symmetrically installed on the outer side of the outer cylinder component. One of the outer support frames is equipped with an irradiation rotary drive for driving the rotation of the inner cylinder component. Several sets of interlocking inner support rods are installed on the inner sides of the two outer support frames. The support plate is sleeved on the outer side of the inner support rod. The docking drive assembly can drive the two outer supports to move horizontally towards each other. The internal welding assembly can weld the docking seams of the inner cylinder component itself, the docking seams of the inner cylinder component and the irradiation rotary drive, the docking seams of the inner support rods in the same group, and the connecting seams between the inner support rods and the support plate. The external welding assembly can weld the docking seams of the outer cylinder component itself and the connecting seams between the outer cylinder component and the outer support frame.

[0008] Furthermore, in the above-mentioned automated welding system for uniform irradiation processing cylinders, the inner cylinder component is formed by joining two half-inner cylinders together. The half-inner cylinder includes an inner cylinder tube, and several radial protrusions are evenly distributed on the outer side of the inner cylinder tube. One end of the inner cylinder tube is connected to a second annular plate via a first annular plate and a first axial tube, and the other end of the inner cylinder tube is connected to a second axial tube via a third annular plate.

[0009] Furthermore, in the aforementioned automated welding system for uniform irradiation processing cylinders, the outer cylinder component is formed by joining two half-outer cylinders. Each half-outer cylinder includes an outer cylinder tube. One end of the outer cylinder tube is connected to a third axial tube via a fourth annular plate, and the other end of the outer cylinder tube is connected to a fourth axial tube via a fifth annular plate. A radiation source mounting tube is provided in the upper middle part of the outer cylinder tube, a feed pipe is provided in the upper front part of the outer cylinder tube, and a discharge pipe is provided in the lower rear part of the outer cylinder tube. The third axial tube is located inside the first axial tube, and the fourth axial tube is located inside the second axial tube.

[0010] Furthermore, in the above-mentioned automated welding system for uniform irradiation processing cylinders, the width of the spiral pusher blade is matched with the difference in inner diameter between the inner and outer cylinders, and the inner side of the spiral pusher blade is evenly distributed with several snap-fit ​​grooves that cooperate with the radial protrusions.

[0011] Furthermore, in the above-mentioned automated welding system for uniform irradiation processing cylinders, the outer support frame is an L-shaped frame composed of vertical support plates and horizontal plates, and the vertical support plates have welding windows that facilitate the passage of internal welding components. Of the two inner support rods in the same group, one has a stepped locking groove with a wider inner surface and a narrower outer surface on the mating surface, and the other has a locking hook on the mating surface.

[0012] Furthermore, in the above-mentioned automated welding system for uniform irradiation processing cylinders, the support plate includes a plate body, the plate body having a central through hole and several through holes that cooperate with the inner support rod, and several support rollers for supporting the inner cylinder components are installed on the outer periphery of the plate body.

[0013] Furthermore, in the above-mentioned automated welding system for uniform irradiation processing cylinders, the docking drive assembly includes a first slide rail, on which two first sliders are mounted, each forming a linear guide pair with the first slide rail. Each first slider has a vacuum suction cup that matches the specifications of the horizontal plate mounted on its upper side.

[0014] Furthermore, in the aforementioned automated welding system for uniform irradiation processing cylinders, the internal welding components include a vertical plate, a screw lifting mechanism, a rotary drive, a connecting plate, a horizontal support, a first drive motor, a rotating arm, and a first welding head. A screw lifting mechanism for vertical displacement is installed on one side of the vertical plate, and a connecting plate is installed on the other side of the vertical plate via the rotary drive. A horizontal support is fixed at the center of the outer side of the connecting plate. A rotating arm driven by the first drive motor is movably supported in the horizontal support. The horizontal support has a storage cavity for accommodating the rotating arm, and first welding heads facing opposite directions are installed at both ends of the rotating arm.

[0015] Furthermore, in the aforementioned automated welding system for uniform irradiation processing cylinders, the external welding assembly includes a second slide rail, a second slider, a lifting push rod, a grooved plate seat, a support shaft, a second welding head, a second drive motor, and a belt drive component. A second slider, forming a linear guide pair, is mounted on the lower side of the second slide rail. The grooved plate seat is supported on the lower side of the second slider via the lifting push rod. The second welding head is supported on both sides of the grooved plate seat via the support shaft. A second drive motor is installed inside the grooved plate seat, and the output shaft of the second drive motor is connected to the support shaft via the belt drive component.

[0016] This invention also provides an automated welding method for a uniformly irradiated processing cylinder, based on the aforementioned automated welding system for a uniformly irradiated processing cylinder, comprising the following steps: S1. Place the two sets of external support frames on the two vacuum suction cups of the docking drive assembly respectively, start the vacuum suction cups to complete the adsorption and fixation of the external support frames, and pre-install and position the assembled half inner cylinder, half outer cylinder, spiral pusher blade, inner support rod and support plate in sequence, so that the spiral pusher blade is engaged with the radial protrusion on the outside of the inner cylinder tube through the snap-fit ​​groove, and the locking hook of the inner support rod in the same group is engaged with the stepped locking groove. The support plate is fitted on the outside of the corresponding inner support rod through the perforation, and the initial alignment and assembly of each component is completed. S2. Start the docking drive assembly. The first slider slides synchronously along the first slide rail, driving the two sets of outer supports to move horizontally towards each other, thereby clamping the two half-outer cylinders. Start the internal welding assembly. The screw lifting mechanism drives the vertical plate to move vertically, extending the rotating arm and the first welding heads at both ends into the interior of the inner cylinder component through the welding window of the outer support. The angle of the horizontal support is adjusted by the rotating drive, so that the first welding head is aligned with the docking seam between the inner cylinder component and the irradiation rotating drive, the docking seam between the inner support rods in the same group, the connection seam between the inner support rod and the support plate, and the docking seam of the inner cylinder component itself in sequence. Spot welding is performed using the first welding head. S3. Start the external welding assembly, adjust the horizontal position of the second welding head by sliding the second slider along the second slide rail, and drive the groove plate seat to rise and fall vertically with the lifting push rod to adjust the welding height of the second welding head. Start the second drive motor, drive the support shaft and the second welding head to rotate through the belt drive component, so that the second welding head successively fits the butt joint of the outer cylinder component itself and the connection joint between the outer cylinder component and the outer support frame, and uses the second welding head to perform spot welding along the weld line.

[0017] The beneficial effects of this invention are: 1. This invention features a docking drive assembly. Through a sliding rail and slider combined with a vacuum suction cup, it achieves the facing alignment and controllable gap fit of the two sets of outer supports and inner and outer cylinder components. This ensures a smooth and even fit between the inner and outer cylinder mating surfaces, and uniform gaps between the mating seams of all components, avoiding the problems of large alignment deviations and uneven joint gaps associated with traditional manual welding. Precise welding and assembly accuracy effectively guarantees the coaxiality and fit accuracy of the double-layer cylinder and the spiral pusher blades, ensuring stable dynamic flipping irradiation of the single-layer seed during subsequent operation, thus guaranteeing irradiation uniformity from the production and processing end.

[0018] 2. This invention adopts a dual-welding component partitioned operation structure. The internal welding component can penetrate into the interior of the inner cylinder component through the welding window of the outer support frame via a rotating arm structure. The first welding head is sequentially aligned with the butt joint between the inner cylinder component and the irradiation rotary drive, the butt joint between the inner support rods in the same group, the connection joint between the inner support rod and the support plate, and the butt joint of the inner cylinder component itself, and spot welding is performed using the first welding head. The second welding head of the external welding component can fit into the butt joint of the outer cylinder component itself and the connection joint between the outer cylinder component and the outer support frame, and spot welding is performed using the second welding head along the weld line.

[0019] 3. The combined irradiation processing cylinder of this invention features a reasonable design. Through automated, zoned welding, the overall structural strength and assembly stability of the processing cylinder are significantly improved. Simultaneous welding of inner and outer seams eliminates defects such as incomplete or false welds, effectively preventing weld cracking and component loosening during long-term irradiation operations and cylinder rotation. Furthermore, the standardized automated welding mode enables homogeneous production of batch processing cylinders, ensuring high consistency in structural parameters and assembly precision for each unit. This completely resolves the individual differences caused by traditional manual welding, guaranteeing the stability and data accuracy of subsequent irradiation breeding experiments. It is suitable for large-scale, standardized seed irradiation breeding production and research scenarios, significantly reducing subsequent maintenance costs and extending equipment lifespan.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, this embodiment provides an automated welding system for a uniform irradiation processing cylinder, including a docking drive assembly 1, an internal welding assembly 2, and an external welding assembly 3. The internal welding assembly 2 is located in the area between the docking drive assembly 1 and the external welding assembly 3. The three work together to complete the automated operations of workpiece alignment, internal concealed weld welding, and external exposed weld welding, respectively, adapting to the welding requirements of the split structure of the combined irradiation processing cylinder 4.

[0025] like Figures 2-3 As shown, the combined irradiation processing cylinder 4 to be processed consists of an inner cylinder component 41, a spiral pusher blade 42, an outer cylinder component 43, an outer support frame 44, an irradiation rotary actuator 45, inner support rods 46, and a support plate 47. The spiral pusher blade 42 is snapped onto the outer side of the inner cylinder component 41. The outer cylinder component 43 is fitted together on the outer sides of the inner cylinder component 41 and the spiral pusher blade 42. The outer support frame 44 is symmetrically installed on the outer side of the outer cylinder component 43. One of the outer support frames 44 is equipped with an irradiation rotary actuator 45 for driving the rotation of the inner cylinder component 41. Several sets of interlocking inner support rods 46 are installed on the inner sides of the two outer support frames 44. The support plate 47 is fitted on the outer side of the inner support rods 46. The combined irradiation processing cylinder 4 is a split-type combined structure. The components work together to achieve the function of dynamic and uniform seed irradiation. At the same time, the split structure is adapted to the step-by-step welding process of this automated welding system.

[0026] like Figures 4-5As shown, the inner cylinder component 41 is formed by joining two half-inner cylinders. Each half-inner cylinder includes an inner cylinder tube 411. Several radial protrusions 412 are evenly distributed on the outer side of the inner cylinder tube 411. One end of the inner cylinder tube 411 is connected to a second annular plate 415 via a first annular plate 413 and a first axial tube 414. The other end of the inner cylinder tube 411 is connected to a second axial tube 417 via a third annular plate 416. The inner cylinder component 41 serves as the inner support layer of the cylinder body and is formed by joining two half-inner cylinders. The inner cylinder tube 411 is the carrier of the seed irradiation cavity. The radial protrusions 412 evenly distributed on the outer side are used to engage and position with the spiral pusher blade 42, limiting the circumferential and axial displacement of the blade and ensuring assembly accuracy. The annular plates and axial tube structures at both ends achieve coaxial nesting assembly of the inner and outer cylinders, improving the overall structural sealing and stability. The spiral pusher blade 42 is a dynamic seed-turning component. The inner snap-fit ​​groove 421 and the radial protrusion 412 snap together to achieve pre-installation positioning without bolt fixation. With the gap space of the double-layer cylinder, it can drive the seeds to continuously turn and spread out when the cylinder rotates, eliminating the irradiation blind zone and ensuring that the seeds are irradiated evenly in all directions. The blade width is adapted to the difference in the inner diameter of the inner and outer cylinders, which can separate the irradiation chamber and avoid seed accumulation.

[0027] like Figure 8 As shown, the outer cylinder component 43 is formed by connecting two half-outer cylinders. The half-outer cylinder includes an outer cylinder tube 431. One end of the outer cylinder tube 431 is connected to a third axial tube 433 via a fourth annular plate 432. The other end of the outer cylinder tube 431 is connected to a fourth axial tube 435 via a fifth annular plate 434. A radiation source mounting tube 436 is provided in the middle of the upper side of the outer cylinder tube 431. A feed pipe 437 is provided in the front of the upper side of the outer cylinder tube 431. A discharge pipe 438 is provided in the rear of the lower side of the outer cylinder tube 431. The third axial tube 433 is located inside the first axial tube 414, and the fourth axial tube 435 is located inside the second axial tube 417. The outer cylinder component 43 serves as an integrated carrier for outer protection and irradiation. After the two half-outer cylinders are joined together, they form a double-layer hollow irradiation cavity with the inner cylinder component 41. The radiation source installation pipe 436 is used to install the irradiation ray generating device. The feed pipe 437 and discharge pipe 438 realize the automatic feeding and discharging of seeds, respectively, and realize the automation of irradiation operation. The annular pipe structure at both ends is nested with the axial pipe of the inner cylinder to ensure the coaxiality of the double-layer cylinder and avoid jamming or displacement during rotation.

[0028] like Figures 6-7 As shown, the width of the spiral pusher blade 42 is matched with the difference in inner diameter between the inner tube 411 and the outer tube 431. The inner side of the spiral pusher blade 42 is evenly distributed with several snap-fit ​​grooves 421 that match the radial protrusions 412.

[0029] like Figure 9As shown, the outer support frame 44 is an L-shaped frame composed of a vertical support plate 441 and a horizontal plate 442. The vertical support plate 441 has a welding window 443 to facilitate the passage of the internal welding assembly 2. The outer support frame 44 is the supporting and fixing structure of the entire equipment. The L-shaped structure has both load-bearing and positioning functions. The horizontal plate 442 is used to dock and fix with the docking drive assembly 1. The welding window 443 of the vertical support plate 441 provides a working channel for the internal welding assembly 2, allowing the welding head to be smoothly inserted into the cylinder for operation, without affecting the overall support strength.

[0030] like Figure 10 As shown, of the two inner support rods 46 in the same group, one has a stepped locking groove 461 with a wider inner surface and a narrower outer surface on the mating surface, and the other has a locking hook 462 on the mating surface that can extend into the stepped locking groove 461.

[0031] like Figure 11 As shown, the support plate 47 includes a plate body 471, which has a central through hole 472 and several through holes 473 that cooperate with the inner support rod 46. Several support rollers 474 for supporting the inner cylinder component 41 are installed on the outer periphery of the plate body 471.

[0032] The inner support rod 46 and the support plate 47 constitute an internal auxiliary support and positioning structure. The inner support rod 46 in the same group interlocks with the locking hook 462 through the stepped locking groove 461 to achieve a gapless connection and improve the stability of the internal support. The support plate 47 is fitted to the outside of the inner support rod 46 through the through hole 473. The outer peripheral support roller 474 can provide rolling support for the inner cylinder component 41, reduce the frictional resistance during the rotation of the cylinder, ensure the smooth rotation of the cylinder, and avoid problems such as seed accumulation and uneven irradiation caused by eccentric shaking. The central through hole 472 is used to avoid the central irradiation beam path and does not affect the normal irradiation operation of the beam.

[0033] The irradiation rotary drive 45 is a cylinder rotation power component, welded and fixed to the inner side of the outer support frame 44. It can drive the inner cylinder component 41 and the spiral pusher blade 42 to rotate at a uniform speed, realizing dynamic flipping irradiation of seeds. It is a power structure that ensures the uniformity of irradiation of the equipment.

[0034] The docking drive assembly 1 can drive the two outer support frames 44 to move horizontally towards each other. The internal welding assembly 2 can weld the docking seam of the inner cylinder component 41 itself, the docking seam between the inner cylinder component 41 and the irradiation rotary drive 45, the docking seam of the inner support rod 46 in the same group, and the connection seam between the inner support rod 46 and the support plate 47. The external welding assembly 3 can weld the docking seam of the outer cylinder component 43 itself and the connection seam between the outer cylinder component 43 and the outer support frame 44.

[0035] like Figure 12As shown, the docking drive assembly 1 includes a first slide rail 11, on which two first sliders 12 are installed, each forming a linear guide pair with the first slide rail 11. Each first slider 12 has a vacuum suction cup 13 that matches the specifications of the horizontal plate 442 installed on its upper side, and the outer support frame 44 is fixed by the principle of vacuum negative pressure adsorption.

[0036] like Figures 13-14 As shown, the internal welding assembly 2 includes a vertical plate 21, a screw lifting mechanism 22, a tilting and rotating drive 23, a connecting plate 24, a horizontal support frame 25, a first drive motor 26, a rotating arm 27, and a first welding head 28. A screw lifting mechanism 22 for driving its vertical displacement is installed on one side of the vertical plate 21. A connecting plate 24 is installed on the other side of the vertical plate 21 via the tilting and rotating drive 23. A horizontal support frame 25 is fixed at the center of the outer side of the connecting plate 24. A rotating arm 27 driven by the first drive motor 26 is movably supported in the horizontal support frame 25. A storage cavity for storing the rotating arm 27 is provided in the horizontal support frame 25. First welding heads 28 facing opposite directions are installed at both ends of the rotating arm 27.

[0037] Internal welding assembly 2 is a welding mechanism for concealed welds inside the equipment. It is designed for welding operations inside the cylinder, on support rods, and in connections to the actuators—areas inaccessible from the outside. It features multi-dimensional adjustment capabilities including lifting, tilting, and rotation, making it suitable for welding in confined internal spaces. Its principle involves using a multi-degree-of-freedom adjustment structure to extend dual welding heads into the workpiece, aligning them with various internal weld seams to complete spot welding. Among them, the screw lifting mechanism 22 is the vertical adjustment power source, which converts the rotational motion into linear lifting motion through the screw nut transmission principle, controls the vertical height of the vertical plate 21, and realizes the adjustment of the welding head insertion depth; the flipping rotary driver 23 adopts a servo rotary drive structure, which can drive the connecting plate 24 and subsequent components to flip the overall angle, realize the all-round adjustment of the welding angle, and adapt to butt welds of different angles; the horizontal support 25 is the bearing base, which is used to support the rotating arm 27 and the first drive motor 26, and also has a built-in storage cavity to store the rotating arm 27 when not in operation, avoiding workpiece clamping interference; the first drive motor 26 is the rotating arm rotation power source, which can drive the rotating arm 27 to rotate horizontally, causing the first welding head 28 with opposite ends to flip outward.

[0038] like Figure 15 As shown, the external welding assembly 3 includes a second slide rail 31, a second slider 32, a lifting push rod 33, a slotted plate seat 34, a support shaft 35, a second welding head 36, a second drive motor 37, and a belt drive component 38. The second slider 32, which forms a linear guide pair with the second slide rail 31, is installed on the lower side of the second slide rail 31. The slotted plate seat 34 is supported on the lower side of the second slider 32 by the lifting push rod 33. The second welding head 36 is supported on the two side plates of the slotted plate seat 34 by the support shaft 35. The second drive motor 37 is installed inside the slotted plate seat 34. The output shaft of the second drive motor 37 is connected to the support shaft 35 via the belt drive component 38.

[0039] The external welding assembly 3 is used for automated welding of exposed weld seams on the exterior of the workpiece. The second slide rail 31 and the second slider 32 constitute a horizontal linear motion mechanism to adjust the horizontal position of the second welding head 36 and adapt to external weld seams of different lengths. The lifting push rod 33 is a vertical telescopic drive mechanism that uses the electric push rod transmission principle to adjust the vertical height of the slotted plate seat 34 and the second welding head 36 to match welding points of different heights. The slotted plate seat 34 is the component bearing base, providing a stable installation reference for the transmission structure and the welding head. The second drive motor 37 is a rotational power source that transmits power to the support shaft 35 through the belt drive component 38, driving the second welding head 36 to rotate at a uniform speed, so that the welding head can stably move along the arc-shaped or linear external weld seam trajectory.

[0040] This embodiment also provides an automated welding method for a uniformly irradiated irradiation processing cylinder, the specific steps of which are as follows: S1. Place the two sets of outer support frames 44 on the surfaces of the two vacuum suction cups 13 of the docking drive assembly 1, respectively. Activate the vacuum suction cups 13 to firmly fix the outer support frames 44 using the negative pressure adsorption principle, preventing displacement during operation. Then, complete the pre-assembly and alignment of the semi-inner cylinder, semi-outer cylinder, spiral pusher blade 42, inner support rod 46, and support plate 47 in sequence. Precisely engage the snap-fit ​​groove 421 of the spiral pusher blade 42 with the radial protrusion 412 on the outer side of the inner cylinder tube 411 to achieve rapid positioning and installation of the blade. Snap the locking hook 462 of the inner support rod 46 into the stepped locking groove 461 to achieve interlocking docking of the rods. Fit the support plate 47 onto the outer side of the corresponding inner support rod 46 through the through hole 473 to complete the preliminary pre-assembly and alignment of all components, ensuring that each docking gap has a uniform welding allowance.

[0041] S2. Start the docking drive assembly 1, control the two first sliders 12 to slide synchronously towards each other along the first slide rail 11, drive the two sets of outer support frames 44 to smoothly approach each other, clamp the two half-outer cylinders for precise docking, and lock the cylinder assembly position. Then start the internal welding assembly 2, drive the vertical plate 21 to rise and fall vertically through the screw lifting mechanism 22, precisely adjust the working height, and pass the rotating arm 27 and the first welding heads 28 at both ends through the welding window 443 of the outer support frame 44, and smoothly extend into the working area inside the inner cylinder component 41. Adjust the overall angle of the horizontal support frame 25 by flipping the rotary drive 23, and drive the rotating arm 27 to rotate in conjunction with the first drive motor 26, drive the first welding head 28 to accurately align, and sequentially complete the automated spot welding operations of the inner cylinder component 41's own docking seam, the inner cylinder component 41 and the irradiation rotary drive 45 docking seam, the inner support rod 46 of the same group docking seam, and the inner support rod 46 and the support plate 47 connection seam.
