The main shaft box and the tail shaft box are oppositely arranged at the upper ends of the machine base along the horizontal direction. A driving shaft, a first motor and a first telescopic assembly are arranged in the main shaft box. Compared with the current layer winding device for welding wire production, the application is provided with a transfer mechanism. In the feeding and discharging link, the transfer mechanism can complete the rapid positioning of the winding reel without accurate alignment. In cooperation with the flexible clamping of the fastening assembly, the winding reel of different specifications can be adapted, and the winding reel can be effectively prevented from being laterally displaced or falling off during the transfer process. In addition, the coincidence degree of the axes of the driving shaft and the driven shaft can be detected in advance before winding through the cooperation of the first clamping assembly and the second clamping assembly, so that the quality problems, such as winding deviation and welding wire arrangement disorder, caused by the axis deviation can be eliminated from the source.

Description

Technical Field

[0001] This invention relates to the field of welding wire layer winding technology, specifically a layer winding device for welding wire production with automatic loading and unloading capabilities. Background Technology

[0002] In the welding wire production process, the layer winding device is a key piece of equipment to achieve orderly winding of welding wire and ensure product quality. Its core function is to evenly wind the produced welding wire onto the winding spool according to the preset arrangement, forming a finished coil that is easy to store, transport and use. Its performance directly affects production efficiency and finished product quality.

[0003] For example, patents "CN219469273U A Welding Wire Layer Winding Device" and "CN222729179U A Welding Wire Layer Winding Device" both disclose a technical solution for welding wire layer winding. However, existing welding wire layer winding devices generally rely on manual precise alignment or special tooling assistance in the loading and unloading process. The positioning and fixing of the winding reel is cumbersome, which not only consumes a lot of manpower and time, but also easily leads to subsequent operations being hindered due to alignment deviations. At the same time, existing welding wire layer winding devices lack an effective pre-inspection and correction mechanism for axis coincidence. The axis deviation between the driving shaft and the driven shaft is difficult to detect in time, which can easily lead to welding wire deviation, disordered arrangement, and problems such as accumulation, overlap, or loosening during the winding process. Finally, most current layer winding devices adopt a single power source design. Once the power source fails, it is necessary to stop the machine for repair or replacement, which leads to the interruption of the entire production process. The fault handling process is cumbersome and the downtime is long, which not only causes a lot of production losses, but also affects the normal progress of subsequent processes, making it difficult to ensure the continuity and stability of production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic loading and unloading device for producing welding wire in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a layer winding device for welding wire production with automatic loading and unloading, comprising a base, a main spindle box, and a tail spindle box. The main spindle box and the tail spindle box are arranged opposite each other at the upper ends of the base in a horizontal direction. The main spindle box contains a drive shaft, a first motor, and a first telescopic assembly. The tail spindle box contains a driven shaft and a second telescopic assembly. The base serves as the supporting foundation for the entire device. The first motor drives the drive shaft to rotate around its own axis, and the first telescopic assembly drives the drive shaft to reciprocate in a horizontal direction along its own axis. The driven shaft is driven to reciprocate horizontally along its own axis via a second telescopic component. The machine base houses a lead screw drive and a transfer mechanism. The transfer mechanism is connected to the working end of the lead screw drive via a mounting bracket. A first clamping component and a second clamping component are respectively located at the ends of the driving and driven shafts that are close to each other. Before operation, the first and second clamping components can be used to pre-check the alignment of the axes of the driving and driven shafts, ensuring precise alignment before starting subsequent operations, thus preventing axis deviation from the source. To address issues such as winding misalignment and disordered welding wire arrangement, after pre-inspection, the winding reel is placed onto the transfer mechanism using a robotic arm or manually. The transfer mechanism is then driven upwards by a lead screw until the axis of the winding reel is aligned with the axes of the drive and driven shafts. At this point, the first and second telescopic components are activated, driving the drive and driven shafts closer together. The winding reel is then secured using the first and second clamping components. After the winding reel is secured, the transfer mechanism is driven downwards by the lead screw. The first motor is activated to continuously wind the welding wire onto the winding reel. When the winding reel reaches the preset amount of welding wire, the first motor is turned off. Then, the transfer mechanism is driven to rise via the lead screw drive until it supports the winding reel after the wire is wound. Subsequently, the first and second telescopic components release the fixing constraints of the first and second clamping components on the winding reel. The transfer mechanism is then driven to descend to a suitable height via the lead screw drive so that the winding reel carrying the finished welding wire can be accurately transported to the designated storage area by a robotic arm or manual operation.

[0006] Furthermore, the transfer mechanism includes a transfer seat, the upper end of which is provided with two arc-shaped grooves, and each arc-shaped groove has a fastening component on its side. The lower end of the transfer seat is provided with a second air pump, which is connected to the two fastening components through a diversion channel. The second air pump controls the opening and closing of the two fastening components. The winding reel in this invention has an I-shaped structure. During the movement of the winding reel, the two side plates of the winding reel are respectively located in the two arc-shaped grooves. Through the fastening components provided on the side of each arc-shaped groove, the winding reel can be limited and fixed from the side, preventing it from shifting or falling off due to inertia during movement. In addition, the width of the arc-shaped groove in this invention is greater than the width of the side plate of the winding reel, so that the side plate of the winding reel can be easily placed into the arc-shaped groove, and the initial positioning can be completed without precise alignment, thereby improving the loading and unloading efficiency.

[0007] Furthermore, the fastening assembly includes fastening blocks, a first telescopic groove, and a second telescopic groove. The first and second telescopic grooves are respectively located on both sides of the arc-shaped groove. Both the first and second telescopic grooves are connected to the diversion channel. This design allows the second air pump to deliver compressed air into the first and second telescopic grooves at any time. Two fastening blocks are provided, positioned opposite each other at both ends inside the arc-shaped groove. One fastening block is connected to the first telescopic groove via a first T-shaped bracket and a first compression spring, while the other fastening block is connected to the second telescopic groove via a second T-shaped bracket and a second compression spring. When the transfer mechanism is not carrying the winding reel, both the first and second compression springs are in a naturally extended state. Two fastening blocks are located at the two ends of the inner arc-shaped groove to facilitate the smooth placement of the winding reel into the groove. When the transfer mechanism carries the winding reel (i.e., the side plate of the winding reel is located in the arc-shaped groove), the second air pump is activated, supplying compressed air to the first and second telescopic grooves. Under the action of air pressure, the first and second T-shaped frames drive the two fastening blocks to move closer to each other, clamping the side plate of the winding reel with the two fastening blocks, so that the winding reel is stably fixed in the arc-shaped groove. Compared with the loading and unloading methods used in current layer winding devices, this invention eliminates the need for precise positioning and can reliably clamp winding reels of different specifications, greatly improving the safety and stability of the winding reel loading and unloading transfer process.

[0008] Furthermore, a first sleeve is provided on the outer side of one end of the drive shaft located inside the spindle box. The first sleeve is connected to the drive shaft by a key. Through the above technical solution, on the one hand, it is ensured that the first sleeve and the drive shaft can rotate synchronously, and on the other hand, the drive shaft has the ability to move axially. The first motor is connected to the first sleeve through a first clutch and a first gear assembly. The first gear assembly plays the role of adjusting the speed and transmitting torque, so that the power of the first motor is adapted and converted and transmitted to the first sleeve, thereby driving the drive shaft to rotate. The first telescopic component includes a first cylinder and a first slider. The first slider is slidably installed on the end of the drive shaft away from the first clamping component. The working end of the first cylinder is connected to the first slider. Through the joint action of the first cylinder and the first slider, the drive shaft is controlled to move axially to realize the telescopic action, thereby facilitating the transfer mechanism to accurately transport the winding reel to the designated position.

[0009] Furthermore, the first clamping assembly includes a first clamping plate, and the second clamping assembly includes a second clamping plate. A mounting base is provided at the end of the first clamping plate away from the drive shaft, and a plurality of positioning holes are provided at the end of the mounting base away from the first clamping plate. A plurality of positioning rods are provided at the end of the second clamping plate away from the driven shaft. The positioning rods cooperate with the positioning holes. When the transfer mechanism transports the winding reel to a designated position between the drive shaft and the driven shaft, the first and second telescopic components drive the first and second clamping plates to approach each other. During the process of gradually fitting towards both ends of the winding reel, the positioning rods on the second clamping plate will insert into the positioning holes. Through the combined action of the positioning rods and the positioning holes, the drive shaft and the driven shaft are connected together, ensuring that they rotate at the same speed and avoiding uneven force on the winding reel caused by the difference in their rotational speeds.

[0010] Furthermore, a photoelectric element is provided in the positioning hole, and a laser emitter is provided at the end of the positioning rod away from the second clamping plate. Before the winding operation, the operator can turn on the laser emitter and the first motor, which drives the drive shaft to rotate. If the alignment of the axes of the drive shaft and the driven shaft meets the standard, the positioning hole on the mounting base will align with the positioning rod on the second clamping plate after the drive shaft rotates to a certain angle. The photoelectric element in the positioning hole will receive a laser signal that meets the standard. If there is a deviation between the axes of the drive shaft and the driven shaft, the positioning hole on the mounting base will not be accurately aligned with the positioning rod on the second clamping plate. In this case, the photoelectric element in the positioning hole will not receive a laser signal that meets the standard. Through the above technical solution, the operator can easily judge whether the alignment of the axes of the drive shaft and the driven shaft meets the standard before the operation, avoiding the disorder of the welding wire during the winding process. Finally, the diameter of the first clamping plate and the second clamping plate in this invention is smaller than the diameter of the winding reel side plate, so that when the winding reel reaches the preset welding wire winding amount, the transfer mechanism can smoothly lift and fix the winding reel.

[0011] Furthermore, the mounting base is provided with three storage slots, each containing a correction frame. One end of the correction frame is located within the storage slot and wound with a third compression spring, while the other end extends out of the storage slot and has an arc-shaped structure. A first air pump is installed inside the spindle box, and an air guide pipe is installed inside the drive shaft. One end of the air guide pipe is connected to the three storage slots, and the other end is connected to the first air pump via a sealed connecting pipe. Before the winding operation begins, the arc-shaped ends of the three correction frames are in contact with the outer wall of the mounting base. In the initial stage of the winding operation, when the first telescopic component and the second telescopic component drive the drive shaft and the driven shaft to approach each other, and the first clamping plate and the second... After the clamping disc and the two ends of the winding disc are in contact, the operator can turn on the first air pump to deliver compressed air into the three receiving slots through the first air pump and the air guide pipe. This ensures that the three calibration frames extend to the same length. Under the force of the three calibration frames, the winding disc is pressed tightly to ensure that the winding disc does not shake during the winding process. On the other hand, the three calibration frames can correct the position of the winding disc to ensure that the axis of the winding disc coincides with the axis of the drive shaft and the driven shaft. This prevents the accuracy of the lead screw drive from decreasing after long-term operation, which could lead to errors in the height at which the lead screw drive drives the transfer mechanism to rise, making it difficult for the axis of the subsequent winding disc to completely coincide with the axis of the drive shaft and the driven shaft.

[0012] Furthermore, the second telescopic component includes a second cylinder and a second slider. The second slider is slidably mounted on the end of the driven shaft away from the second clamping component. The working end of the second cylinder is connected to the second slider. The driven shaft is controlled to reciprocate along its own axis in the horizontal direction by the second cylinder and the second slider, so as to realize the flexible adjustment of the distance between the driven shaft and the driving shaft.

[0013] Furthermore, a second motor is also provided inside the tail shaft box. A second sleeve is provided on the outer side of one end of the driven shaft located inside the tail shaft box. The second sleeve is connected to the driven shaft by a key. The second motor is connected to the second sleeve through a second clutch and a second gear assembly. During normal operation, the second motor is in a non-working state, and the second motor is disconnected from the second gear assembly through the second clutch. The first motor serves as the power source of the invention, driving the drive shaft, winding disc, and driven shaft to rotate. When the first motor fails, the operator can disconnect the first motor from the first gear assembly through the first clutch and connect the second motor to the second gear assembly through the second clutch. At this time, the second motor can drive the drive shaft, winding disc, and driven shaft to rotate. Through the above technical solution, the invention overcomes the phenomenon of work interruption that may be caused by a single power source. When the main power source fails, the backup power source can be quickly switched and intervened, and the operation can be restored without complicated operations, greatly reducing downtime and avoiding production losses and efficiency reductions caused by downtime, thus significantly enhancing the operational reliability of the entire layer winding device.

[0014] Furthermore, the winding device also includes a wire laying mechanism, which is located on the side of the machine base. The guide wire end of the wire laying mechanism faces the winding reel. During the winding operation, the welding wire is led out through the guide wire end of the wire laying mechanism. The wire laying mechanism can guide the welding wire to be evenly distributed along the axial direction of the winding reel, avoiding the welding wire from piling up, overlapping or becoming loose during the winding process.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with the current layer winding device for welding wire production, the present invention is equipped with a transfer mechanism. In the loading and unloading process, the transfer mechanism can quickly position the winding reel without precise alignment. With the flexible clamping of the fastening components, it can not only adapt to different specifications of winding reels, but also effectively prevent the winding reel from shifting or falling off during the transfer process, greatly improving the safety and stability of loading and unloading. In addition, the present invention can detect the overlap of the axes of the driving shaft and the driven shaft in advance before winding through the cooperation of the first clamping component and the second clamping component, eliminating quality problems such as winding deviation and disordered welding wire arrangement caused by axis deviation from the root. The three correction frames in the first clamping component can correct the winding... The winding reel is fixed a second time. On the other hand, by correcting the position of the winding reel, the accuracy of the lead screw drive component is prevented from decreasing after long-term operation. This prevents errors in the height at which the lead screw drive component drives the transfer mechanism, making it difficult for the axis of the subsequent winding reel to be completely aligned with the axes of the drive shaft and the driven shaft. Finally, the invention also has the ability to quickly switch between dual power sources, breaking the predicament of existing technologies where a single power source easily leads to work interruption. When the main power source suddenly fails, the backup power source can be started without complicated operations to quickly restore work, greatly reducing downtime and avoiding production losses caused by downtime. This significantly enhances the ability to ensure continuous operation of the device, making the overall production process more stable and smooth, and reducing operational risks.

[0027] 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.

[0028] Example: Figures 1-10As shown, the present invention provides a technical solution: an automatic loading and unloading welding wire production layer winding device, comprising a base 1, a main spindle box 2, and a tail spindle box 4. The main spindle box 2 and the tail spindle box 4 are arranged horizontally opposite each other at the upper ends of the base 1. The main spindle box 2 is equipped with a drive shaft 23, a first motor 21, and a first telescopic assembly. The tail spindle box 4 is equipped with a driven shaft 43 and a second telescopic assembly. The base 1 serves as the supporting foundation for the entire device. The first motor 21 drives the drive shaft 23 to rotate around its own axis, and the first telescopic assembly drives the drive shaft 23 to reciprocate horizontally along its own axis. The second telescopic assembly drives the drive shaft 23 to reciprocate horizontally. The driven shaft 43 reciprocates horizontally along its own axis. A lead screw drive 11 and a transfer mechanism 6 are installed inside the machine base 1. The transfer mechanism 6 is connected to the working end of the lead screw drive 11 via a mounting bracket. A first clamping assembly 231 and a second clamping assembly 431 are respectively installed at the ends of the driven shaft 23 and the driven shaft 43 that are close to each other. Before operation, the first clamping assembly 231 and the second clamping assembly 431 can be used to pre-check the alignment of the axes of the driven shaft 23 and the driven shaft 43, ensuring precise alignment before starting subsequent operations. This fundamentally avoids winding deviation caused by axis misalignment. To address issues such as disordered welding wire arrangement, after pre-inspection, the winding reel 3 is placed onto the transfer mechanism 6 using a robotic arm or manually. Then, the transfer mechanism 6 is driven upwards by the lead screw drive 11 until the axis of the winding reel 3 is aligned with the axes of the drive shaft 23 and the driven shaft 43. At this point, the first and second telescopic components are activated, driving the drive shaft 23 and the driven shaft 43 closer together. The winding reel 3 is then fixed by the first clamping component 231 and the second clamping component 431. After the winding reel 3 is fixed, the transfer mechanism 6 is driven downwards by the lead screw drive 11. The first motor 21 is turned on so that the welding wire continues to be wound on the winding reel 3. When the winding reel 3 reaches the preset amount of welding wire, the first motor 21 is turned off. Then, the transfer mechanism 6 is driven to rise by the lead screw drive 11 until the transfer mechanism 6 supports the winding reel 3 after the wire is wound. Subsequently, the first clamping component 231 and the second clamping component 431 are released from the fixed constraint of the winding reel 3 by the first telescopic component and the second telescopic component. The transfer mechanism 6 is driven to fall to a suitable height by the lead screw drive 11 so that the winding reel 3 carrying the finished welding wire can be accurately transported to the designated storage area by a robot or manual operation.

[0029] like Figures 3-5As shown, the transfer mechanism 6 includes a transfer seat 61. The upper end of the transfer seat 61 is provided with two arc-shaped grooves 66. Each arc-shaped groove 66 has a fastening component on its side. The lower end of the transfer seat 61 is provided with a second air pump 62. The second air pump 62 is connected to the two fastening components through a diversion channel 63. The second air pump 62 controls the opening and closing of the two fastening components. The winding reel 3 in this invention has an I-shaped structure. During the movement of the winding reel 3, the two side plates of the winding reel 3 are respectively located in the two arc-shaped grooves 66. Through the fastening components provided on the side of each arc-shaped groove 66, the winding reel 3 can be limited and fixed from the side, preventing it from shifting or falling off due to inertia during the movement. In addition, the width of the arc-shaped groove 66 in this invention is greater than the width of the side plate of the winding reel 3, so that the side plate of the winding reel 3 can be easily placed into the arc-shaped groove 66, and the initial positioning can be completed without precise alignment, thereby improving the loading and unloading efficiency.

[0030] like Figure 5 As shown, the fastening assembly includes a fastening block 64, a first telescopic groove 65, and a second telescopic groove 67. The first telescopic groove 65 and the second telescopic groove 67 are respectively located on both sides of the arc-shaped groove 66. Both the first telescopic groove 65 and the second telescopic groove 67 are connected to the diversion channel 63. This design allows the second air pump 62 to deliver compressed air into the first telescopic groove 65 and the second telescopic groove 67 at any time. Two fastening blocks 64 are provided, which are arranged opposite each other at both ends inside the arc-shaped groove 66. One fastening block 64 is connected to the first telescopic groove 65 through a first T-shaped bracket and a first compression spring, and the other fastening block 64 is connected to the second telescopic groove 67 through a second T-shaped bracket and a second compression spring. When the transfer mechanism 6 is not carrying the winding reel 3, both the first compression spring and the second compression spring are in a naturally extended state. Two fastening blocks 64 are located at the two ends of the inner arc-shaped groove 66, so that the winding reel 3 can be smoothly placed into the arc-shaped groove 66. When the transfer mechanism 6 carries the winding reel 3 (that is, the side plate of the winding reel 3 is located in the arc-shaped groove 66), the second air pump 62 is started. The second air pump 62 delivers compressed air to the first telescopic groove 65 and the second telescopic groove 67. Under the action of air pressure, the first T-shaped frame and the second T-shaped frame will drive the two fastening blocks 64 to move closer to each other. The two fastening blocks 64 clamp the side plate of the winding reel 3 so that the winding reel 3 is stably fixed in the arc-shaped groove 66. Compared with the loading and unloading method used in the current layer winding device, the present invention does not require precise positioning and can reliably clamp winding reels 3 of different specifications, which greatly improves the safety and stability of the loading and unloading transfer process of the winding reel 3.

[0031] like Figure 3 , Figures 6-7As shown, a first sleeve 24 is provided on the outer side of one end of the drive shaft 23 located inside the spindle box 2. The first sleeve 24 is connected to the drive shaft 23 by a key. Through the above technical solution, on the one hand, it is ensured that the first sleeve 24 and the drive shaft 23 can rotate synchronously, and on the other hand, the drive shaft 23 has the ability to move axially. The first motor 21 is connected to the first sleeve 24 through the first clutch 211 and the first gear assembly 22. The first gear assembly 22 plays the role of adjusting the speed and transmitting torque, so that the power of the first motor 21 is adapted and converted and transmitted to the first sleeve 24, thereby driving the drive shaft 23 to rotate. The first telescopic assembly includes a first cylinder 25 and a first slider 232. The first slider 232 is slidably installed on the end of the drive shaft 23 away from the first clamping assembly 231. The working end of the first cylinder 25 is connected to the first slider 232. Through the joint action of the first cylinder 25 and the first slider 232, the drive shaft 23 is controlled to move axially, so as to realize the telescopic action, thereby facilitating the transfer mechanism 6 to accurately transport the winding reel 3 to the designated position.

[0032] like Figures 8-10 As shown, the first clamping assembly 231 includes a first clamping disk 2311, and the second clamping assembly 431 includes a second clamping disk 4311. A mounting base 2314 is provided at the end of the first clamping disk 2311 away from the drive shaft 23. A plurality of positioning holes 2313 are provided at the end of the mounting base 2314 away from the first clamping disk 2311. A plurality of positioning rods 4312 are provided at the end of the second clamping disk 4311 away from the driven shaft 43. The plurality of positioning rods 4312 cooperate with the plurality of positioning holes 2313. When the transfer mechanism 6 transports the winding disk 3 to the drive shaft 23 and the driven shaft 4311... After the designated position between the moving shafts 43, the first and second telescopic components drive the first clamping plate 2311 and the second clamping plate 4311 to move closer to each other. As they gradually come into contact with the two ends of the winding disc 3, several positioning rods 4312 on the second clamping plate 4311 will be inserted into several positioning holes 2313. Through the combined action of several positioning rods 4312 and several positioning holes 2313, the driving shaft 23 and the driven shaft 43 are connected together, ensuring that they rotate at the same speed and avoiding the problem of uneven force on the winding disc 3 caused by the difference in their rotation speeds.

[0033] like Figure 8 , Figure 10As shown, a photoelectric element is installed inside the positioning hole 2313, and a laser emitter is installed at the end of the positioning rod 4312 away from the second clamping plate 4311. Before the winding operation, the operator can turn on the laser emitter and the first motor 21, which drives the drive shaft 23 to rotate. If the alignment of the axes of the drive shaft 23 and the driven shaft 43 meets the standard, the positioning hole 2313 on the mounting base 2314 will be aligned with the positioning rod 4312 on the second clamping plate 4311 after the drive shaft 23 rotates to a certain angle. The photoelectric element inside the positioning hole 2313 will receive a laser signal that meets the standard. If there is a deviation between the axes of the drive shaft 23 and the driven shaft 43, If the positioning hole 2313 on the mounting base 2314 cannot be precisely aligned with the positioning rod 4312 on the second clamping plate 4311, the photoelectric element in the positioning hole 2313 will not receive a standard laser signal. Through the above technical solution, it is convenient for the staff to judge in time whether the axis coincidence of the active shaft 23 and the driven shaft 43 meets the standard before work, so as to avoid the subsequent welding wire from becoming disordered during the winding process. Finally, the diameter of the first clamping plate 2311 and the second clamping plate 4311 in this invention is smaller than the diameter of the side plate of the winding plate 3, so that when the winding plate 3 reaches the preset welding wire winding amount, the transfer mechanism 6 can smoothly lift and fix the winding plate 3.

[0034] like Figures 7-9As shown, the mounting base 2314 has three storage slots 2315, each containing a correction frame 2312. One end of the correction frame 2312 is located within the storage slot 2315 and wound with a third compression spring, while the other end extends out of the storage slot 2315 and has an arc-shaped structure. A first air pump 26 is installed inside the spindle box 2, and an air guide pipe 233 is installed inside the drive shaft 23. One end of the air guide pipe 233 is connected to the three storage slots 2315, and the other end is connected to the first air pump 26 via a sealed connecting pipe 27. Before the winding operation begins, the arc-shaped ends of the three correction frames 2312 are in contact with the outer wall of the mounting base 2314. At the initial stage of the winding operation, when the first telescopic assembly and the second telescopic assembly drive the drive shaft 23 and the driven shaft 43 to approach each other, and the first clamping plate 231... After the first and second clamping plates 4311 are in contact with the two end faces of the winding disc 3, the operator can turn on the first air pump 26 to deliver compressed air into the three receiving slots 2315 through the first air pump 26 and the air guide pipe 233, so that the three correction frames 2312 extend to the same length. Under the force of the three correction frames 2312, on the one hand, the winding disc 3 is pressed tightly to ensure that the winding disc 3 will not shake during the winding of the welding wire. On the other hand, the position of the winding disc 3 can be corrected by the three correction frames 2312 to ensure that the axis of the winding disc 3 coincides with the axis of the drive shaft 23 and the driven shaft 43. This avoids the accuracy of the lead screw drive 11 decreasing after long-term operation, so that there is an error in the height at which the lead screw drive 11 drives the transfer mechanism 6 to rise, which would make it difficult for the axis of the winding disc 3 to completely coincide with the axis of the drive shaft 23 and the driven shaft 43.

[0035] like Figure 10 As shown, the second telescopic component includes a second cylinder 45 and a second slider 432. The second slider 432 is slidably mounted on the end of the driven shaft 43 away from the second clamping component 431. The working end of the second cylinder 45 is connected to the second slider 432. The driven shaft 43 is controlled to reciprocate along its own axis in the horizontal direction by the second cylinder 45 and the second slider 432, so as to realize the flexible adjustment of the distance between the driven shaft 43 and the driving shaft 23.

[0036] like Figure 10As shown, a second motor 41 is also provided inside the tail shaft housing 4. A second sleeve 44 is provided on the outer side of one end of the driven shaft 43 located inside the tail shaft housing 4. The second sleeve 44 is connected to the driven shaft 43 by a key. The second motor 41 is connected to the second sleeve 44 through a second clutch 411 and a second gear assembly 42. During normal operation, the second motor 41 is in a non-working state, and the second clutch 411 keeps the second motor 41 disconnected from the second gear assembly 42. The first motor 21 serves as the power source of the invention, driving the drive shaft 23, the winding disc 3, and the driven shaft 43 to rotate. When the first motor 21 fails... The operator can disconnect the first motor 21 from the first gear assembly 22 via the first clutch 211, and connect the second motor 41 to the second gear assembly 42 via the second clutch 411. At this time, the second motor 41 can drive the drive shaft 23, the winding disc 3, and the driven shaft 43 to rotate. Through the above technical solution, the present invention breaks the phenomenon of operation interruption that may be caused by a single power source. When the main power source fails, the backup power source can be quickly switched and intervened. The operation can be restored without complicated operation, which greatly reduces the downtime of failure and avoids production losses and efficiency reduction caused by downtime, and significantly enhances the operational reliability of the entire layer winding device.

[0037] like Figure 2 As shown, the layer winding device also includes a wire laying mechanism 5, which is located on the side of the machine base 1. The guide wire end of the wire laying mechanism 5 faces the winding reel 3. During the winding operation, the welding wire is led out through the guide wire end of the wire laying mechanism 5. The wire laying mechanism 5 can guide the welding wire to be evenly distributed along the axial direction of the winding reel 3, so as to avoid the welding wire from piling up, overlapping or becoming loose during the winding process.

[0038] The working principle of this invention is as follows: Before the winding operation, the operator can turn on the laser emitter and the first motor 21 on the second clamping assembly 431. The first motor 21 drives the drive shaft 23 to rotate. By detecting the laser signal received by the photoelectric element on the first clamping assembly 231, the operator indirectly determines whether the alignment of the axes of the drive shaft 23 and the driven shaft 43 meets the standard, thus avoiding problems such as winding offset and disordered welding wire arrangement caused by axis deviation. After the detection is completed, the winding reel 3 is placed on the transfer mechanism 6 by a robot or manually. Then, the transfer mechanism 6 is driven to rise by the lead screw drive 11 until the axis of the winding reel 3 is aligned with the axes of the drive shaft 23 and the driven shaft 43. The drive shaft 23 and the driven shaft 43 are then driven to move closer to each other by the first telescopic assembly and the second telescopic assembly. The winding reel 3 is fixed by the first clamping component 231 and the second clamping component 431. After the winding reel 3 is fixed, the transfer mechanism 6 is driven to move down by the lead screw drive component 11 and the first motor 21 is turned on so that the welding wire continues to be wound on the winding reel 3. When the winding reel 3 reaches the preset amount of welding wire, the first motor 21 is turned off. Then, the transfer mechanism 6 is driven to rise by the lead screw drive component 11 until the transfer mechanism 6 supports the winding reel 3 after the wire is wound. Subsequently, the first telescopic component and the second telescopic component release the fixing constraint of the first clamping component 231 and the second clamping component 431 on the winding reel 3. The transfer mechanism 6 is driven to descend to a suitable height by the lead screw drive component 11 so that the winding reel 3 carrying the finished welding wire can be accurately transported to the designated storage area by a robot or manual operation.
