Description

Technical Field

[0001] This application belongs to the field of welding wire splicing technology, specifically relating to an automatic splicing device for solid welding wire. Background Technology

[0002] During the actual drawing process, the diameter of the welding wire decreases from thick to thin. Since the large shaft does not affect the speed of continuous production, the welding wire is wound onto a large shaft after continuous up-and-down drawing. Because the welding wire is wound onto a large shaft, its volume, height, and weight are all large, making subsequent manual handling difficult. Moreover, the welding wire wound on the large shaft is only initially sorted. To achieve standardized production, it is necessary to further refine the division, evenly outputting the welding wire wound on the large shaft to multiple parallel small shafts.

[0003] However, there's a problem. For example, if each small shaft is required to have a 20kg spool of welding wire wound around it, the spool on the last small shaft might weigh less than 20kg. Therefore, to ensure each spool weighs exactly 20kg to meet factory requirements, the welding wire from the next large shaft needs to be butt-joined with the wire on the spool on the current small shaft to compensate for the weight and reach the set 20kg. However, traditional welding wire butt-joining usually involves manual alignment. Since the diameter of commonly used welding wire is around 0.8mm, the very small diameter makes subtle changes difficult to observe with the naked eye, making manual alignment extremely difficult. If the welding wires are not properly butt-joined, precise winding cannot be achieved.

[0004] Furthermore, while existing wire butt welding devices exist, they still require manual alignment of the wire clamps, leading to alignment deviations during the butt welding process. Secondly, existing devices typically involve inserting electrodes into the wires on both sides, followed by processing with a welding machine and a grinder. Specifically, to create current between the wires, the welding ends are manually squeezed before welding. This manual alignment results in inaccurate results, leading to deviations in the butt welding. Secondly, the squeezing of the welding ends before welding creates large, lumpy weld nodules at the joint. Moreover, the thin wires melt quickly after energizing, further contributing to the problem. The welding wires were not precisely aligned, only roughly aligned, causing large lumps to form quickly at the welding joint. The traditional method of using a butt welding machine compensates for this lack of precise alignment. The machine first connects the two wires, and any large lumps formed during this process are then ground down using an additional grinding machine. Therefore, the existing wire butt welding device not only requires the butt welding machine to compensate for the misalignment but also necessitates the use of a grinding machine to remove the lumps. This grinding machine is used to trim the joint area, ensuring the diameter at the joint matches the diameters of the two wires. If the wire diameter is very thin, such as 0.8mm, the grinding machine needs to grind the lumps down to 0.8mm. This grinding process requires manual operation, holding the wire at the joint and rotating it along a grinding blade, which reduces the grinding precision and further affects the welding accuracy at the joint. Furthermore, after welding and grinding, the joint of the welding wire is prone to cracking. Metal dust and particles generated during grinding easily remain at the wire tip, and these non-metallic impurities can be carried into the molten pool during subsequent welding, forming slag inclusions. Simultaneously, the dust may absorb moisture or oil, leading to gas generation during welding and the formation of pores, severely reducing the weld's density and mechanical properties, and posing a potential crack initiation point. Therefore, existing welding wire butt welding devices not only increase the structural complexity of the device but also further reduce welding efficiency and quality. Utility Model Content

[0005] This application provides an automatic solid welding wire splicing device to solve the problem that in existing welding wire butt welding devices, in order to facilitate the smooth energization between welding wires, the ends of the welding wires need to be squeezed before welding with a welding machine. This not only leads to large lumps of welding nodules at the welding wire joint, but also requires additional grinding equipment for grinding, which not only increases the structural complexity, but also further reduces the welding efficiency and welding quality of the welding wires.

[0006] The technical solution adopted in this application is as follows:

[0007] An automatic connector for solid welding wire includes a base and a central focusing seat, a first moving platform, and a second moving platform connected above the base.

[0008] The first moving platform is slidably connected to one side of the center focusing mount, and the second moving platform is slidably connected to the other side of the center focusing mount;

[0009] The center focusing seat has a docking receiving groove for accommodating welding wire, and a first hole communicating with the docking receiving groove is opened in the center focusing seat. A laser head capable of emitting a laser beam toward the center of the docking receiving groove is connected to the center of the first hole, so that the center of the docking receiving groove forms the focal point for welding wire docking. A first moving platform is connected to a first clamping assembly for clamping welding wire, and a second moving platform is connected to a second clamping assembly for clamping welding wire. The first moving platform and the second moving platform can move relative to the center focusing seat so that the welding wire moves to the focal position of the docking receiving groove to achieve welding head alignment.

[0010] This application employs a central focusing base with a docking groove within it to accommodate welding wires. A first moving platform is positioned on one side of the central focusing base, and a second moving platform is positioned on the other side. One welding wire is held in the first moving platform, and the other welding wire to be docked is held in the second moving platform. The welding wires move relative to the central focusing base via the first and second moving platforms. Because the laser beam from the laser head irradiates the center of the docking groove, the center position of the docking groove becomes the focal point of the laser beam, thus ensuring proper welding wire docking on both sides. The wires are aligned with the laser beam by focusing on the center of the docking groove. Note that the laser beam does not emit laser light during the wire docking process. Instead, it begins to irradiate the wires after they are aligned. Since the wires are aligned with the laser beam's focal point, when the laser beam begins to irradiate the center of the docking groove, the focal point of the laser beam is directly opposite the joint of the two wires. This allows for welding after the two wires are aligned. The laser beam can melt a small portion of the joint of the two wires, thus facilitating the docking of the two wires using a 1000W fiber laser.

[0011] Secondly, traditional welding wire alignment requires manual clamping, alignment, and compression. This application avoids the butt joint deviation caused by manual alignment of the welding wires on both sides, which leads to skewed or bent welding wires after butt joint, affecting the use of the welding wires. Furthermore, traditional methods require fusion butt welding after manual alignment, energizing both welding wires before welding. To ensure current flow, the ends of the two welding wires are compressed before welding, resulting in large lumps at the weld joint. In traditional methods, the welding wires are manually aligned, resulting in only approximate alignment. The welding machine then completes the alignment by melting and welding to correct any misalignment. Because the welding wires are not perfectly aligned before welding, butt joint deviations exist, leading to weld nodules at the weld joint when the welding machine welds the two wires. For weld nodules that appear, additional grinding equipment is required for professional grinding to ensure that the diameter of the butt weld joint is the same as the diameter of the welding wires on both sides. This not only increases the complexity of the equipment structure but also leads to a decrease in precision during the welding wire processing. After welding and grinding, the joint of the welding wire is prone to cracking, as the metal dust and particles generated during grinding are easily retained at the tip of the welding wire. During welding, these non-metallic impurities are carried into the molten pool, forming slag inclusions. At the same time, the dust may absorb moisture or oil, causing gas to be generated during welding, forming pores, which seriously reduces the density and mechanical properties (such as strength and toughness) of the weld and is a potential crack initiation point.

[0012] In a preferred embodiment, the docking receiving groove extends through the center focusing seat along the width direction of the center focusing seat, so that the welding wire can be inserted into the docking receiving groove from both sides to complete the docking; one side of the docking receiving groove extends through the center focusing seat along the top, so that the welding wire can be taken out from the top of the docking receiving groove for welding wire wiring.

[0013] The mating receiving groove of this application extends through the width of the center focusing seat. Its purpose is to accommodate the welding wires on both sides to complete the mating within the mating receiving groove, providing a precise mating position for the welding wires on both sides. It also facilitates the laser beam to irradiate the center position of the mating receiving groove to achieve precise mating of the welding wires on both sides. Furthermore, the purpose of extending the top of the mating receiving groove through the center focusing seat is to make the top of the mating receiving groove have an upward-facing opening, which makes it easier to remove the welding wire for wiring in the next step.

[0014] In a preferred embodiment, the center focusing seat has a first hole, a second hole, and a third hole on one side along its length that communicate with the docking receiving groove; a first camera is connected to the first hole, a first lighting lamp is connected to the second hole, and a second camera is connected to the third hole.

[0015] The center focusing base of this application has a first hole, a second hole, and a third hole on one side for mounting a first camera, a first lighting lamp, and a second camera, respectively. The first camera and the second camera are used to capture images of the welding wires on both sides and upload the image information to the controller in real time. The controller can determine the position of the welding wire based on the image information and control the corresponding first and second moving platforms to move the welding wire to the center of the docking receiving groove, i.e., the focal position of the laser beam. The first lighting lamp is set to provide a light source for the first camera and the second camera to capture high-definition image information.

[0016] In a preferred embodiment, the first camera includes a first camera body and a first protective sleeve; the first camera body is sleeved and connected inside the first protective sleeve, an internal thread is provided in the first hole, an external thread is provided on the outside of the first protective sleeve, and the first protective sleeve and the first hole are connected by threads, so that the first camera can move along the first hole.

[0017] In order to enable the position of the first camera to be adjustable along the axis of the first hole, this application provides an internal thread inside the first hole and an external thread on the outside of the first protective sleeve. The threaded connection also enables the positioning of the first camera, facilitating the adjustment of the position relative to the welding wire during practical applications.

[0018] In a preferred embodiment, the center focusing mount has a fourth hole, a fifth hole, and a sixth hole on the other side along its length; the fourth hole is symmetrically arranged with the first hole and a second lighting lamp is connected inside the fourth hole; the fifth hole is symmetrically arranged with the second hole and a laser head is connected inside the fifth hole; the sixth hole is symmetrically arranged with the third hole and a third lighting lamp is connected inside the sixth hole.

[0019] The purpose of having a fourth, fifth, and sixth hole on the other side of the center focusing base is to install the second illumination lamp, the laser head, and the third illumination lamp, respectively. The laser head is positioned on the opposite side of the camera to separate it from the first and second cameras. If the first camera, the second camera, and the laser head were all on the same side, the lens diameter would be directly facing the extremely strong laser beam. This would cause severe overexposure of the laser line area in the camera image, turning it into a white bright spot without any detail. It would be impossible to see the welding wire connection position, let alone clearly observe the weld bevel and working surface condition of the welding wire connection on both sides. Therefore, separating the laser head from the first and second cameras on both sides of the calibration base avoids the strong direct laser beam, forming a clear field of view without interference or overexposure within the connection receiving groove.

[0020] In a preferred embodiment, the second lighting lamp includes a second lighting lamp body and a first positioning sleeve; the second lighting lamp body is sleeved and connected inside the first positioning sleeve, the outer side of the first positioning sleeve is provided with external threads, and the fourth hole is provided with internal threads, and the first positioning sleeve is threadedly connected to the fourth hole so that the second lighting lamp is movably connected to the fourth hole.

[0021] In order to enable the position of the first positioning sleeve to be adjustable along the axial direction of the fourth hole, the fourth hole is provided with an internal thread and the outer side of the first positioning sleeve is provided with an external thread. The position of the first positioning sleeve can also be positioned through the threaded connection, which facilitates the adjustment of the position relative to the welding wire in actual application.

[0022] In a preferred embodiment, the first clamping assembly includes a first cylinder and a first gripper assembly. The first cylinder is slidably connected to a first slider and a second slider that move relative to each other. The first gripper assembly includes a first gripper and a second gripper. The first gripper is connected to the first slider, and the second gripper is connected to the second slider.

[0023] This application provides a first clamping assembly on a first mobile platform. The first clamping assembly includes a first gripper and a second gripper that move relative to each other. The first gripper and the second gripper have a finger-like structure that allows them to move crosswise, thereby clamping welding wires of different diameters. This not only enables circumferential clamping of welding wires of different diameters and stable welding wire docking, but also prevents over-clamping of the welding wires from causing them to deflect, thereby further improving the efficiency and accuracy of welding wire docking.

[0024] In a preferred embodiment, the second clamping assembly includes a second cylinder and a second gripper assembly. The second cylinder is slidably connected to a third slider and a fourth slider that move relative to each other. The second gripper assembly includes a third gripper and a fourth gripper. The third gripper is connected to the third slider, and the fourth gripper is connected to the fourth slider.

[0025] This application provides a second clamping assembly on a second mobile platform. The second clamping assembly includes a third and a fourth gripper that move relative to each other. The third and fourth grippers have a finger-like structure that allows them to move crosswise, thereby clamping welding wires of different diameters. This not only enables circumferential clamping of welding wires of different diameters and stable welding wire but also prevents over-clamping of the welding wires from causing them to deflect, thus further improving the efficiency and accuracy of welding wire welding.

[0026] In a preferred embodiment, the first mobile platform includes a base plate, a partition plate, and a top plate; the base plate is slidably connected to the base along the length direction of the base, the partition plate is slidably connected above the base plate along the width direction of the base, and the top plate is slidably connected above the partition plate along the vertical direction.

[0027] The base plate of the first moving platform of this application can move along the X-axis of the base, allowing the welding wire to move along the X-axis and align with the focal point in the receiving groove. The partition plate can move along the Y-axis of the base plate, allowing the welding wire to move along the Y-axis and align with the focal point in the receiving groove. The top plate is slidably connected above the partition plate, allowing the welding wire to move along the Z-axis and align with the focal point in the receiving groove. After the six-axis robot picks up the welding wire and transports it to the first moving platform, the first moving platform enables the welding wire to be precisely moved into the receiving groove and aligned with the focal point of the laser beam, facilitating precise alignment with the welding wire of the second moving platform in the receiving groove later.

[0028] In a preferred embodiment, the second mobile platform includes a base, a partition, and a top platform; the base is slidably connected to the base along the length direction of the base, the partition is slidably connected above the base along the width direction of the base, and the top platform is slidably connected above the partition in a vertical direction.

[0029] The base of the second moving platform of this application can move along the X-axis of the base, so that the welding wire can move along the X-axis and align the welding wire with the focal point in the receiving groove along the X-axis; the partition can move along the Y-axis of the base, so that the welding wire can move along the Y-axis and align the welding wire with the focal point in the receiving groove along the Y-axis; the top platform is slidably connected above the partition, so that the welding wire can move along the Z-axis and align the welding wire with the focal point of the laser beam in the receiving groove along the Z-axis, thereby achieving precise alignment of the welding wire of the second moving platform and the welding wire of the first moving platform in the receiving groove.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0031] 1. This application establishes a central focusing base with a docking groove within it for accommodating welding wires. A first moving platform is positioned on one side of the central focusing base, and a second moving platform is positioned on the other side. One welding wire is held in the first moving platform, and another welding wire to be docked is held in the second moving platform. The welding wires move relative to the central focusing base via the first and second moving platforms. Because the laser beam from the laser head irradiates the center of the docking groove, the center position of the docking groove becomes the focal point of the laser beam. The welding wires on both sides can be aligned with the laser beam focal point by focusing on the center of the docking receiving groove. It is important to note that the laser beam does not emit laser light during the welding wire docking process. Instead, it begins to irradiate the welding wires after they are aligned. Since the welding wires are aligned with the focal point of the laser beam, when the laser beam begins to irradiate the center of the docking receiving groove, the focal point of the laser beam is directly opposite the joint of the welding wires on both sides. This enables welding after the welding wires on both sides are aligned. The laser beam can melt a small amount at the joint of the welding wires on both sides, which facilitates the docking of the welding wires on both sides by the fiber laser.

[0032] Secondly, traditional welding wires require manual clamping, alignment, and compression during the alignment process. This application avoids the butt joint deviation caused by the traditional manual alignment of the welding heads of the two welding wires, which leads to the welding wires being skewed and bent after the welding wires are joined, affecting the use of the welding wires.

[0033] Furthermore, traditional methods, after manual alignment, require a welding machine to fuse the welding wires on both sides. To ensure current flow between the two wires, the ends need to be squeezed before welding, resulting in large lumps at the joint. Manual alignment only requires approximate alignment, with the welding machine used to further align the wires and fill any misalignments. Because the wires are not perfectly aligned before welding, misalignment can occur, leading to weld nodules at the weld joint. These nodules require specialized grinding to ensure the weld joint diameter matches the diameter of the two wires. This increases equipment complexity and reduces wire processing precision. After welding and grinding, the joint is prone to cracking, as metal dust and particles from grinding easily remain at the wire ends. During welding, these non-metallic impurities are carried into the molten pool, forming slag inclusions. Meanwhile, dust may absorb moisture or oil, causing gas to be generated during welding, forming pores, which severely reduces the density and mechanical properties (such as strength and toughness) of the weld, and is a potential source of cracks.

[0034] The welding wire of this application can achieve high-precision alignment during butt welding, avoiding large lumps of welding nodules that may appear during the later welding melting process. Therefore, it also eliminates the need for additional grinding machines for finishing, thereby not only improving the quality of butt welding, but also further reducing structural complexity and the use of additional equipment, reducing the floor space and improving production efficiency.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0048] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0049] This application relates to an automatic splicing device for solid welding wire, such as... Figure 1-6 As shown, it includes a base 1 and a center focusing base 2, a first moving platform 3 and a second moving platform 4 connected above the base 1;

[0050] The first moving platform 3 is slidably connected to one side of the center focusing seat 2, and the second moving platform 4 is slidably connected to the other side of the center focusing seat 2. The center focusing seat 2 has a docking receiving groove 20 for accommodating the welding wire 19, and a first hole 7 is opened in the center focusing seat 2 to communicate with the docking receiving groove 20. A laser head 17 that can emit a laser beam toward the center of the docking receiving groove 20 is connected to the center of the first hole 7, so that the center of the docking receiving groove 20 forms the focal point for the welding wire 19 to dock. The first moving platform 3 is connected to a first clamping assembly 5 for clamping the welding wire 19, and the second moving platform 4 is connected to a second clamping assembly 6 for clamping the welding wire 19. The first moving platform 3 and the second moving platform 4 can move relative to the center focusing seat 2 so that the welding wire 19 moves to the focal position of the docking receiving groove 20 to achieve welding head alignment.

[0051] This application establishes a central focusing base 2, within which is a docking receiving groove 20 for accommodating welding wires 19. A first moving platform 3 is located on one side of the central focusing base 2, and a second moving platform 4 is located on the other side. One welding wire 19 is held in the first moving platform 3, and another welding wire 19 to be docked is held in the second moving platform 4. The welding wires 19 move relative to the central focusing base 2 via the first moving platform 3 and the second moving platform 4. Because the laser beam from the laser head 17 irradiates the docking receiving groove 20, the center position of the docking receiving groove 20 forms the focal point of the laser head 17. By aligning the welding wires 19 on both sides with the center of the docking receiving groove 20, the laser beam can be focused. Note that the laser beam does not emit laser light during the welding wires 19 docking process. Instead, the laser beam begins to irradiate the welding wires 19 after they are aligned. Since the welding wires 19 are aligned with the focal point of the laser beam, when the laser beam begins to irradiate the docking receiving groove 20, the focal point of the laser beam is directly opposite the joint of the welding wires 19 on both sides, thus achieving welding after the welding wires 19 on both sides are aligned. The laser beam can melt a small amount at the joint of the welding wires 19 on both sides, which is conducive to the docking of the welding wires 19 on both sides by the 1000W fiber laser.

[0052] Traditionally, both welding wires 19 need to be energized, and to ensure current flow between them, the ends of the two wires 19 need to be squeezed together before welding, resulting in large lumps at the joint. Secondly, traditional alignment of the welding wires 19 requires manual clamping, alignment, and squeezing. This application avoids the butt joint deviations caused by manual alignment of the welding heads of the two welding wires 19, which leads to skewed or bent welding wires after welding, affecting their usability. Furthermore, traditional methods require fusion welding after manual alignment, while manual alignment only needs approximate alignment. The welding process further aligns the wires, filling in any misalignments. Since the welding wires 19 are not precisely aligned before welding, this method avoids these issues. The presence of misalignment can also cause large, lumpy weld nodules to appear at the weld joint where the welding wires 19 on both sides meet. These weld nodules require specialized grinding with additional equipment such as grinders to ensure the diameter of the weld joint is the same as the diameter of the two welding wires 19. This not only increases the complexity of the equipment structure but also reduces the precision of the welding wires 19 during processing. After welding and grinding, the joint of the welding wires 19 is prone to cracking, as the metal dust and particles generated during grinding easily remain at the ends of the welding wires 19. During welding, these non-metallic impurities are carried into the molten pool, forming slag inclusions. Simultaneously, the dust may absorb moisture or oil, leading to gas generation during welding and the formation of pores, severely reducing the density and mechanical properties of the weld, such as strength and toughness, and acting as a potential source of cracks. The welding wire 19 of this application can achieve high-precision alignment during butt welding, avoiding large lumps of welding nodules that appear during the later welding melting process. Therefore, it can further avoid the need to use a grinding machine for finishing, thereby not only improving the quality of butt welding, but also further reducing structural complexity and the use of additional equipment, reducing the floor space and improving production efficiency.

[0053] In a preferred embodiment, the docking receiving groove 20 extends through the center focusing seat 2 along the width direction of the center focusing seat 2, so that the welding wire 19 can be inserted into the docking receiving groove 20 from both sides to complete the docking; one side of the docking receiving groove 20 extends through the center focusing seat 2 along the top, so that the welding wire 19 can be taken out from the top of the docking receiving groove 20 for welding wire 19 wiring.

[0054] The docking receiving groove 20 of this application extends through the width of the center focusing seat 2. Its purpose is to accommodate the welding wires 19 on both sides to complete the docking within the docking receiving groove 20, providing a precise docking position for the welding wires 19 on both sides. It also facilitates the laser beam to irradiate the center position of the docking receiving groove 20 to achieve precise docking of the welding wires 19 on both sides. Furthermore, the purpose of extending the top of the docking receiving groove 20 through the center focusing seat 2 is to make the top of the docking receiving groove 20 have an upward-facing opening, which makes it easier to remove the welding wires 19 for wiring in the next step.

[0055] In a preferred embodiment, the center focusing base 2 has a first hole 7, a second hole 8 and a third hole 9 connected to the docking receiving groove 20 on one side along the length direction; a first camera 10 is connected in the first hole 7, a first lighting lamp 11 is connected in the second hole 8 and a second camera 12 is connected in the third hole 9.

[0056] The center focusing base 2 of this application has a first hole 7, a second hole 8, and a third hole 9 on one side for mounting a first camera 10, a first lighting lamp 11, and a second camera 12, respectively. The first camera 10 and the second camera 12 are used to capture images of the welding wires 19 on both sides and upload the image information to the controller in real time. The controller can determine the position of the welding wires 19 based on the image information and control the corresponding first moving platform 3 and the second moving platform 4 to move the welding wires 19 to the center of the docking receiving groove 20, that is, the focal position of the laser beam. The first lighting lamp 11 is set to provide a light source for the first camera 10 and the second camera 12 to capture high-definition image information.

[0057] In a preferred embodiment, the first camera 10 includes a first camera 10 body and a first protective sleeve; the first camera 10 body is sleeved and connected inside the first protective sleeve, the first hole 7 has an internal thread, the first protective sleeve has an external thread, and the first protective sleeve and the first hole 7 are connected by threads, so that the first camera 10 can move along the first hole 7.

[0058] In order to enable the position of the first camera 10 to be adjustable along the axis of the first hole 7, the first hole 7 is provided with an internal thread and the outer side of the first protective sleeve is provided with an external thread. The position of the first camera 10 can also be positioned through the threaded connection, which facilitates the adjustment of the position relative to the welding wire 19 in actual application.

[0059] In a preferred embodiment, a fourth hole 13, a fifth hole 14, and a sixth hole 15 are provided on the other side along the length direction of the center focusing base 2; the fourth hole 13 is symmetrically arranged with the first hole 7, and a second lighting lamp 16 is connected inside the fourth hole 13; the fifth hole 14 is symmetrically arranged with the second hole 8, and a laser head 17 is connected inside the fifth hole 14; the sixth hole 15 is symmetrically arranged with the third hole 9, and a third lighting lamp 18 is connected inside the sixth hole 15.

[0060] The purpose of having a fourth hole 13, a fifth hole 14, and a sixth hole 15 on the other side of the center focusing base 2 is to install the second illumination lamp 16, the laser head 17, and the third illumination lamp 18, respectively. The purpose of setting the laser head 17 on the opposite side of the camera is to separate it from the first camera 10 and the second camera 12. If the first camera 10, the second camera 12, and the laser head 17 are set on the same side, the lens will be directly facing the extremely strong laser beam. This will cause the laser line area in the camera image to be severely overexposed, turning into a white bright spot without any details. It will be impossible to see the docking position of the welding wire 19, let alone clearly observe the weld bevel and working surface of the welding wires 19 on both sides. Therefore, the laser head 17 is separated from the first camera 10 and the second camera 12 on both sides of the calibration base 1, avoiding the strong direct laser beam and forming a clear field of view without interference or overexposure within the docking receiving groove 20.

[0061] In a preferred embodiment, the second lighting lamp 16 includes a second lighting lamp 16 body and a first positioning sleeve; the second lighting lamp 16 body is sleeved and connected to the first positioning sleeve, the outer side of the first positioning sleeve is provided with external thread, and the fourth hole 13 is provided with internal thread, and the first positioning sleeve is threadedly connected to the fourth hole 13 so that the second lighting lamp 16 is movably connected to the fourth hole 13.

[0062] In order to enable the position of the first positioning sleeve to be adjustable along the axial direction of the fourth hole 13, the fourth hole 13 is provided with an internal thread and the first positioning sleeve is provided with an external thread. The position of the first positioning sleeve can also be positioned through the threaded connection, which facilitates the adjustment of the position relative to the welding wire 19 in actual application.

[0063] In a preferred embodiment, the first clamping assembly 5 includes a first cylinder 51 and a first gripper assembly 52. ​​The first cylinder 51 is slidably connected to a first slider 511 and a second slider 512 that move relative to each other. The first gripper assembly 52 includes a first gripper 521 and a second gripper 522. The first gripper 521 is connected to the first slider 511, and the second gripper 522 is connected to the second slider 512.

[0064] This application provides a first clamping assembly 5 on a first mobile platform 3. The first clamping assembly 5 includes a first gripper 521 and a second gripper 522 that move relative to each other. The first gripper 521 and the second gripper 522 have a finger-like structure that allows them to move crosswise, thereby clamping welding wires 19 of different diameters. This not only enables circumferential clamping of welding wires 19 of different diameters and stable docking of the welding wires 19, but also prevents over-clamping of the welding wires 19 from causing them to deflect, thereby further improving the efficiency and accuracy of welding wire docking.

[0065] In a preferred embodiment, the second clamping assembly 6 includes a second cylinder 61 and a second gripper assembly 62. The second cylinder 61 is slidably connected to a third slider and a fourth slider that move relative to each other. The second gripper assembly 62 includes a third gripper and a fourth gripper. The third gripper is connected to the third slider, and the fourth gripper is connected to the fourth slider.

[0066] This application provides a second clamping assembly 6 on a second moving platform 4. The second clamping assembly 6 is equipped with a third gripper and a fourth gripper that move relative to each other. The third gripper and the fourth gripper have a finger-like structure that allows them to move crosswise, thereby clamping welding wires 19 of different diameters. This not only enables circumferential clamping of welding wires 19 of different diameters and stable docking of the welding wires 19, but also prevents over-clamping of the welding wires 19 from causing them to deflect, thereby further improving the efficiency and accuracy of welding wire docking.

[0067] In a preferred embodiment, the first mobile platform 3 includes a base plate 31, a partition plate 32, and a top plate 33; the base plate 31 is slidably connected to the base 1 along the length direction of the base 1, the partition plate 32 is slidably connected above the base plate 31 along the width direction of the base 1, and the top plate 33 is slidably connected above the partition plate 32 along the vertical direction.

[0068] The base plate 31 of the first moving platform 3 of this application can move along the X-axis direction of the base 1, allowing the welding wire 19 to move along the X-axis direction so that the welding wire 19 is aligned with the focal point in the receiving groove along the X-axis direction; the partition plate 32 can move along the Y-axis direction of the base plate 31, allowing the welding wire 19 to move along the Y-axis direction so that the welding wire 19 is aligned with the focal point in the receiving groove 20 along the Y-axis direction; the top plate 33 is slidably connected above the partition plate 32 so that the welding wire 19 can move along the Z-axis direction so that the welding wire 19 is aligned with the focal point of the laser beam in the receiving groove 20 along the Z-axis direction. After the six-axis robot picks up the welding wire 19 and transports it to the first moving platform 3, the welding wire 19 can be accurately moved to the receiving groove 20 and aligned with the focal point of the laser beam by setting the first moving platform 3, which facilitates the subsequent accurate alignment of the welding wire 19 with the welding wire 19 of the second moving platform 4 in the receiving groove 20. Figure 5As shown in Figure C, this represents the butt weld position. After the two welding wires are precisely aligned at the focal point of the butt groove, the laser head is activated so that the laser beam irradiates the focal point, which corresponds precisely to the butt weld position. This causes a point of melting at the welding ends of the two welding wires, allowing for precise butt welding. The resulting butt weld does not produce large lumps, avoiding the large lumps that occur in traditional methods where the welding wires are energized and their ends are pressed together. Traditional methods also require grinding, which not only demands high precision and increases operational difficulty but also reduces welding quality, hindering future wire use. This application avoids these problems, creating a butt weld with the same diameter as the welding wires immediately after welding, eliminating the need for grinding.

[0069] In a preferred embodiment, the second mobile platform 4 includes a base 41, a partition 42, and a top platform 43; the base 41 is slidably connected to the base 1 along the length direction of the base 1, the partition 42 is slidably connected above the base 41 along the width direction of the base 1, and the top platform 43 is slidably connected above the partition 42 along the vertical direction.

[0070] The base 41 of the second moving platform 4 of this application can move along the X-axis direction of the base 1, so that the welding wire 19 can move along the X-axis direction and align the welding wire 19 with the focal point in the receiving groove along the X-axis direction; the partition 42 can move along the Y-axis direction of the base 41, so that the welding wire 19 can move along the Y-axis direction and align the welding wire 19 with the focal point in the receiving groove 20 along the Y-axis direction; the top platform 43 is slidably connected above the partition 42, so that the welding wire 19 can move along the Z-axis direction and align the welding wire 19 with the focal point of the laser beam in the receiving groove 20 along the Z-axis direction, thereby achieving precise alignment of the welding wire 19 of the second moving platform 4 and the welding wire 19 of the first moving platform 3 in the receiving groove 20.
