[0002] As a crucial component of clean energy, wind power generation relies heavily on its tower, a key structural element supporting the wind turbine. The welding quality of the cable fixing brackets inside the tower directly impacts the stability of the cable arrangement and the overall reliability of the tower. Traditional welding methods, primarily manual, have the following drawbacks:

[0003] Difficulty in precision control: Manual welding is easily affected by operating techniques and fatigue, resulting in poor precision in the welding position of various components of the support frame and poor consistency in weld quality. This may lead to insecure cable fixation and affect the operational stability of wind power generation equipment.

It has extremely high practical value and broad application prospects, and will strongly promote the technological progress and development of the wind power tower cable fixing bracket manufacturing industry.

[0043] In this embodiment, the pick-up welding device 5 includes a frame 51, a lifting mechanism 52, a lateral translation mechanism 53, a rotating mechanism 54, a pick-up component 55, a longitudinal translation mechanism 56, and a telescopic welding mechanism 57. The frame 51 is erected on both sides of the conveying device 1. The lifting mechanism 52 is mounted on the frame 51. The lateral translation mechanism 53 is mounted on the lifting mechanism 52, and the lifting mechanism 52 drives the lateral translation mechanism 53 to move up and down. The rotating mechanism 54 is mounted on the lateral translation mechanism 53, and the lateral translation mechanism 53 drives the rotating mechanism 54 to move closer to or further away from the positioning device 3 from both sides of the conveying device 1. The pick-up component 55 is mounted on the rotating mechanism 54, and the rotating mechanism 54 drives the pick-up component 55 to rotate the upright plate 20 picked up by the pick-up component 55 by 90 degrees, so as to rotate the upright plate 20 from a horizontal state to a vertical state. The longitudinal translation mechanism 56 is mounted on the lifting mechanism 52, and the lifting mechanism 52 drives the longitudinal translation mechanism 56 to move up and down. The telescopic welding mechanism 57 is installed on the longitudinal translation mechanism 56, and is driven by the longitudinal translation mechanism 56 to move along the welding line between the connecting plate 10 and the vertical plate 20. The telescopic welding mechanism 57 performs welding by telescopically moving and contacting the welding line.

[0044] The pick-up and welding device 5 of this invention, through the organic combination and precise linkage of multiple components such as the frame 51, lifting mechanism 52, and lateral translation mechanism 53, achieves efficient pick-up, precise positioning, and high-quality welding of the upright plate 20. It demonstrates significant advantages in improving welding automation, efficiency, and accuracy, providing key technical support for the efficient operation of automatic welding machines for wind power tower cable fixing brackets. Specific beneficial effects are as follows:

[0045] I. Achieving Precise and Efficient Operation: The frame 51 is erected on both sides of the conveying device 1, providing stable support for the entire picking and welding device 5 and ensuring the stability of subsequent mechanisms. The lifting mechanism 52, in conjunction with the lateral translation mechanism 53, can drive the rotating mechanism 54 to achieve precise lifting and lateral movement, allowing it to accurately approach or move away from the connecting plate 10 and the upright plate 20 at the positioning device 3. Driven by the rotating mechanism 54, the picking component 55 can accurately pick up the upright plate 20 and rotate it 90 degrees from a horizontal position to a vertical position. This process is precise in positioning and rapid in action. Compared with traditional manual picking and flipping, it greatly improves the processing efficiency and accuracy of the upright plate 20 and reduces errors and time losses caused by manual operation.

[0046] II. Ensuring High-Quality Welding: The longitudinal translation mechanism 56 and the lifting mechanism 52 work together to achieve lifting movement, driving the telescopic welding mechanism 57 to adjust its height. Simultaneously, driven by the longitudinal translation mechanism 56, the telescopic welding mechanism 57 can precisely move along the welding line between the connecting plate 10 and the upright plate 20. Welding is performed by telescopically contacting the welding line, allowing flexible control of the welding position and depth according to welding requirements. This ensures that the welding torch and welding line are in close contact during the welding process, effectively reducing welding defects such as incomplete welds and missed welds. This guarantees the strength and uniformity of the weld between the upright plate 20 and the connecting plate 10, significantly improving welding quality and effectively ensuring the structural strength of the fixed bracket.

[0047] III. Enhancing Equipment Operational Stability: Through precise mechanical connections and transmission design, the various mechanisms work closely together during operation, ensuring smooth power transmission. For example, the linkage control between the lateral translation mechanism 53 and the rotation mechanism 54, and between the longitudinal translation mechanism 56 and the telescopic welding mechanism 57, ensures smooth overall operation of the device during a series of actions such as picking, rotating, positioning, and welding. This reduces the risk of vibration and malfunction caused by improper coordination between components, extends the service life of the equipment, and guarantees the continuity and stability of the production process.

[0048] In summary, the pick-up welding device 5 of this invention, with its scientific structural design and precise coordinated operation of various mechanisms, effectively overcomes the shortcomings of traditional welding methods in terms of efficiency, precision, and versatility, significantly improving the overall performance of the automatic welding machine for wind power tower cable fixing brackets. This pick-up welding device 5 enables automated, high-quality welding production, possesses extremely high practical value and promising market prospects, and will bring positive technological innovation and economic benefits to the wind power equipment manufacturing industry.

[0049] Please see Figures 5 to 7 In this embodiment, the lifting mechanism 52 includes a lifting drive component 521, a push plate 522, guide shafts 523, and a lifting plate 524. The lifting drive component 521 is mounted on the frame 51, and the push plate 522 is installed at the lifting end of the lifting drive component 521. Two guide shafts 523 are slidably mounted on the frame 51, with the top ends of the two guide shafts 523 connected to the push plate 522 and the bottom ends of the two guide shafts 523 fixed to the lifting plate 524. A lateral translation mechanism 53 is mounted on the lifting plate 524. The lifting drive component 521 can be a cylinder, an electric cylinder, or the like. The lifting mechanism 52 of the present invention drives the push plate 522 through the lifting drive component 521 to drive the two guide shafts 523 to slide up and down on the frame 51, thereby enabling the lifting plate 524 fixed at the bottom of the guide shafts 523 to stably support the transverse translation mechanism 53 to achieve precise lifting and lowering movements. Its structural design ensures the stability and accuracy of the lifting process through the guiding effect of the guide shafts 523, providing reliable vertical movement support for the overall precise operation of the picking welding device.

[0050] In this embodiment, the lateral translation mechanism 53 includes a translation rack 531, a translation gear 532, and a translation motor 533. Two parallel translation racks 531 are reciprocally slidably mounted on the lifting plate 524. The translation gear 532 meshes between the two translation racks 531. The translation motor 533 is mounted on the lifting plate 524, and its output shaft is connected to the translation gear 532. A rotation mechanism 54 is mounted on each translation rack 531. The translation motor 533 drives the translation gear 532 to rotate, thereby causing the two translation racks 531 to slide in opposite directions. The lateral translation mechanism 53 of the present invention drives the translation gear 532 to rotate via the translation motor 533, which in turn drives two parallel translation racks 531 that mesh with each other on both sides of the translation gear 532 to slide in opposite directions. This enables the rotation mechanism 54 mounted on the translation racks 531 to move laterally in a synchronous and symmetrical manner, so that the two picked-up upright plates 20 are clamped on both sides of the connecting plate 10. The transmission structure of the gear rack not only ensures the consistency and accuracy of the movement of the rotation mechanism 54 on both sides, but also achieves smooth and shock-free reciprocating sliding through the motor drive. This provides reliable lateral positioning support for the upright plate picking and welding process, effectively improving the overall motion accuracy and collaborative operation efficiency of the device.

[0051] In this embodiment, the rotating mechanism 54 includes a rotating plate 541 and a rotating drive component 542. The rotating plate 541 is hinged to one end of the translation rack 531, and one end of the rotating drive component 542 is hinged to the translation rack 531, while the other end is hinged to the rotating plate 541 to drive the rotating plate 541 to reciprocate 90 degrees. The pickup component 55 is mounted on the rotating plate 541. The rotating drive component 542 can be a cylinder, electric cylinder, etc. The rotating mechanism 54 of the present invention, through the rotating drive component 542 being hinged to the translation rack 531 and the rotating plate 541 at both ends respectively, drives the rotating plate 541, which is hinged to one end of the translation rack 531, to achieve a reciprocating 90-degree rotation. Its hinged drive structure not only ensures the accurate flipping of the upright plate from a horizontal to a vertical state after pickup, but also ensures the reliability and repeatability of the rotation action through the stable output of the rotating drive component 542, providing accurate angular positioning for the vertical welding of the upright plate and the connecting plate, effectively improving the automation accuracy and work efficiency of the welding process.

[0052] In this embodiment, the pickup component 55 can use a physical suction cup or an electromagnetic adsorption component to pick up the upright plate 20. The pickup component 55 of the present invention uses a vacuum suction cup or an electromagnetic adsorption component to pick up the upright plate 20. This adsorption method can firmly adsorb the upright plate, and at the same time, it ensures a stable grip when it is rotated 90 degrees in conjunction with the rotating mechanism. Compared with traditional mechanical grippers, it not only significantly improves the versatility of working conditions, but also effectively enhances the level of automation and operational safety of upright plate picking.

[0053] In this embodiment, the longitudinal translation mechanism 56 includes a fixed base 561, a lead screw 562, a guide rail, a sliding block 564, and a welding motor 565. The fixed base 561 is mounted on the bottom of the lifting plate 524. The lead screw 562 is rotatably mounted on the fixed base 561 and extends axially along the conveying direction of the conveying device 1. The guide rail is mounted on the fixed base 561 and arranged parallel to the lead screw 562. The sliding block 564 is screwed onto the lead screw 562 and slidably mounted on the guide rail. The welding motor 565 is mounted on one end of the fixed base 561 and connected to one end of the lead screw 562. The telescopic welding mechanism 57 is mounted on the sliding block 564. The longitudinal translation mechanism 56 of the present invention drives the lead screw 562 to rotate via the welding motor 565, so that the sliding block 564, which is screwed to the lead screw 562 and slides along the guide rail, achieves stable linear motion along the conveying direction of the conveying device 1. This drives the telescopic welding mechanism 57, which is mounted on the sliding block 564, to move precisely along the welding line between the connecting plate 10 and the vertical plate 20. The transmission structure of the lead screw and guide rail not only ensures the high precision and low friction of the telescopic welding mechanism 57, but also enables flexible adjustment of the welding position through the precise control of the welding motor 565, effectively improving the automation level of the welding operation and the stability of the weld quality.

[0054] In this embodiment, the telescopic welding mechanism 57 includes a welding torch 571, a telescopic rack 572, a synchronizing gear 573, a lifting rack 574, and a telescopic drive component 575. Two welding torches 571 and two telescopic racks 572 are provided, each welding torch 571 being elastically and telescopically mounted on one end of the corresponding telescopic rack 572. The two telescopic racks 572 are symmetrically arranged in a figure-eight shape and are reciprocally slidably mounted on a sliding block 564. Two synchronizing gears 573 are respectively meshed between the two telescopic racks 572. The lifting rack 574 is meshed between the two synchronizing gears 573. The telescopic drive component 575 is mounted on the sliding block 564 and connected to the lifting rack 574 to drive its lifting and sliding motion. The telescopic drive component 575 can be a cylinder, an electric cylinder, or the like. The lifting rack 574 drives two synchronous gears 573 to rotate, thereby causing the welding torches 571 at one end of the two telescopic racks 572 to tilt downwards and move closer to or away from the welding line between the connecting plate 10 and the upright plate 20. The telescopic welding mechanism 57 of this invention, through the linkage design of two symmetrically arranged telescopic racks 572 in a figure-eight shape with synchronous gears 573 and lifting racks 574, achieves synchronous tilting and telescopic movement of the two welding torches 571. This structure not only precisely controls the welding torches 571 to approach the welding line at the optimal angle, effectively avoiding visual obstruction and spatter interference during the welding process, but also adaptively compensates for minor unevenness on the surface of the weldment through its elastic telescopic design, ensuring welding stability. Simultaneously, the symmetrical arrangement of the two welding torches 571 allows for simultaneous welding of the upright plates 20 on both sides of the connecting plate 10, improving welding efficiency while ensuring uniform welding stress distribution and significantly reducing weldment deformation. Compared to the traditional single welding torch structure, this significantly improves welding quality and production efficiency, while reducing equipment energy consumption and maintenance costs.

[0055] Please see Figures 1 to 3 In this embodiment, the conveying device 1 includes a conveying frame 11 and two conveyor belts 12 arranged at intervals. Each conveyor belt 12 is wound around two drive wheels 13 on each side of the conveying frame 11. A slide rail for sliding support of the conveyor belt 12 is installed on the conveying frame 11. The conveyor belt 12 is driven to rotate by driving the drive wheels 13. The positioning device 3 is located between the two conveyor belts 12. The conveying device 1 of the present invention adopts a structural design in which the conveying frame 11 cooperates with two conveyor belts 12 arranged at intervals, and the conveyor belts 12 are driven to rotate by the drive wheels 13. This design not only stably carries and conveys the connecting plate 10, but the symmetrical layout of the two conveyor belts 12 can also effectively prevent the connecting plate 10 from shifting during the conveying process, ensuring transmission stability. At the same time, the positioning device 3 is set between the two conveyor belts 12. When the connecting plate 10 is conveyed to the position, it can quickly block and lift the connecting plate 10 by utilizing the gap between the conveyor belts. This cleverly achieves a seamless connection between the conveying and positioning processes, reduces intermediate transfer links, improves production efficiency, reduces equipment space occupation, and enhances the integration and coordination of the entire automatic welding machine.

[0056] In this embodiment, the connecting plate feeding device 2 includes a feeding box 21, a support plate, and a release drive 23. Two optical shafts 24 extending along the height direction are installed on each side wall of the feeding box 21. The eight optical shafts 24 cooperate to form a positioning space adapted to the connecting plates 10, such that the four corners of the stacked connecting plates 10 inside the feeding box 21 are spaced apart from the inner wall of the feeding box 21. The feeding box 21 has openings at both ends, and the height between the bottom of the feeding box 21 and the conveyor belt 12 is approximately equal to the thickness of the connecting plates 10, allowing one connecting plate 10 to pass through at a time. The support plate is vertically mounted at the bottom opening of the feeding box 21. The release drive 23 is mounted on the conveyor frame 11 and connected to the support plate to drive the support plate to move up and down. When it is necessary to release the connecting plate 10, the release drive 23 drives the support plate to descend below the conveyor belt 12. The connecting plate 10 on the support plate falls onto the conveyor belt 12 and is conveyed out by the conveyor belt 12. When the connecting plate 10 has not completely left the connecting plate 10 supported above it, the release drive 23 drives the support plate to rise and block the bottom opening of the feed box 21 to support the remaining connecting plates 10, thereby ensuring that one connecting plate 10 is released at a time. The release drive 23 can be a cylinder, electric cylinder, etc. The connecting plate feeding device 2 of the present invention forms a positioning space adapted to the connecting plate 10 through eight optical shafts 24 on the inner wall of the feeding box 21, so that the four corners of the connecting plate 10 are spaced from the inner wall of the box, effectively avoiding the problems of plate scratches and jamming caused by direct contact in traditional feeding boxes; in conjunction with the liftable support plate and release drive 23, by precisely controlling the lifting height of the support plate, only one connecting plate 10 is released to the conveyor belt 12 at a time, which not only ensures the continuity of feeding, but also ensures the consistency and smoothness of the falling posture of the connecting plate 10 through the guiding effect of the optical shafts 24, significantly improving the accuracy of subsequent positioning and welding processes; this structure can also adapt to connecting plates 10 of different thicknesses by adjusting the stroke of the release drive 23, enhancing the versatility of the equipment, reducing manual intervention, reducing labor intensity and feeding error rate, and providing a reliable guarantee for the efficient and stable operation of automated welding production lines.

[0057] In this embodiment, the positioning device 3 includes a blocking drive 31, a positioning plate 32, and a lifting drive 33. The blocking drive 31 is mounted on the conveyor frame 11, and its telescopic rod extends to block the notch of the connecting plate 10. At this time, the conveying device 1 stops conveying. The positioning plate 32 is mounted on the lifting end of the lifting drive 33 and is used to lift the connecting plate 10 off the conveyor belt 12. The lifting drive 33 is mounted on the conveyor frame 11 to drive the positioning plate 32 to rise and fall. The blocking drive 31 and the lifting drive 33 can be cylinders, electric cylinders, etc. The positioning device 3 of the present invention precisely extends the telescopic rod to the notch of the connecting plate 10 through the blocking drive component 31, thereby achieving rapid positioning and interception of the connecting plate 10 during conveying. Combined with the synchronous stop control of the conveying device 1, it effectively avoids the positional deviation caused by the sliding of the plate in the traditional positioning method. The lifting drive component 33 drives the positioning plate 32 to smoothly lift the connecting plate 10 away from the conveyor belt 12, so that the plate is freed from the interference of the conveying power source and is in a suspended state. This not only provides stable support for the subsequent welding process, but also ensures the positional accuracy of the connecting plate 10 in three-dimensional space through the coordinated design of notch positioning and lifting action, significantly improving the welding alignment between the upright plate 20 and the connecting plate 10.

[0058] In this embodiment, the vertical plate feeding device 4 includes a storage bin 41, an electric push rod 42, and a position detection element. Each side wall of the storage bin 41 is equipped with two sliding shafts extending along the height direction. The eight sliding shafts cooperate to form a positioning space adapted to the vertical plate 20, ensuring that the four corners of the stacked vertical plates 20 within the storage bin 41 are spaced apart from the inner wall of the storage bin 41. The storage bin 41 has openings at both ends, and a lifting plate for pushing the vertical plates 20 is installed at the bottom of the storage bin 41. The electric push rod 42 is connected to the lifting plate. The position detection element is installed at the material-retrieving position at the top of the storage bin 41. The position detection element accurately obtains the height position of the vertical plate 20, and the control system, based on the material-retrieving feedback, controls the electric push rod 42 to raise the lifting plate a specified distance, ensuring a constant material-retrieving position. The vertical plate feeding device 4 of this invention constructs a positioning space adapted to the vertical plate 20 within the storage box 41 through eight sliding shafts, avoiding contact and friction between the four corners of the vertical plate 20 and the inner wall of the box, effectively preventing surface damage and stacking jamming. Combined with the electric push rod 42 driving the lifting plate to adjust the stacking height of the vertical plates 20 in real time, and with the top position detection element to accurately monitor the height of the vertical plate 20, the material picking position is dynamically constant, ensuring that the picking and welding device 5 can stably pick up materials at the same position every time, without the need for frequent manual calibration, significantly improving material picking efficiency and accuracy. This structure, through automated closed-loop control, reduces the cost of manual intervention, provides a continuous and stable supply of vertical plates for the automated welding of wind power tower cable fixing brackets, and improves the reliability and stability of production.

[0060] 1. Material feeding and conveying: Within the optical axis positioning space of the connecting plate feeding device 2, the support plate descends under the action of the release drive 23, releasing a single connecting plate 10 to the double conveyor belt 12 of the conveying device 1, which is then driven by the transmission wheel 13 for conveying; the storage box 41 of the vertical plate feeding device 4 uses a sliding shaft to position the vertical plate 20, and the electric push rod 42 keeps the vertical plate 20 in a fixed material picking position according to the feedback from the position detection element.

[0061] 2. Precise positioning: The connecting plate 10 is conveyed to the positioning device 3, the blocking drive component 31 is inserted into the notch for positioning, the conveying device 1 stops, and the lifting drive component 33 drives the positioning plate 32 to lift it away from the conveyor belt 12.

[0062] III. Plate Processing and Welding: The lifting mechanism 52 of the picking and welding device 5 drives the horizontal translation mechanism 3 to descend, the picking part 55 picks up the plate 20, and after being rotated 90 degrees by the rotating mechanism 54, it is moved to the two sides of the connecting plate 10 for positioning; the double welding gun 571 tilts and approaches under the linkage of gear and rack, elastically extending and retracting to adapt to the welding part, and the longitudinal translation mechanism 56 drives the double welding gun 571 to move along the welding line, and symmetrical welding is completed.

[0063] IV. Cyclic Production: After welding, the positioning device 3 lowers the connecting plate 10 and outputs it through the conveyor belt 12. All devices are reset, and a new round of welding cycle is started. The timing is controlled by the PLC system.
