[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] This utility model provides a laser welding device, aiming to solve the problem of low production efficiency caused by excessively long manual adjustment time when changing modules in traditional triaxial laser welding machines during the prototyping or small-batch production stages. Referring to Figures 1 and 2, an embodiment of the laser welding device of this utility model includes: a horizontal motion component 1; a vertical motion component 2 connected to the horizontal motion component 1, the vertical motion component 2 moving within a preset horizontal area, the vertical motion component 2 including a first vertical linear motion module 21 and a second vertical linear motion module 22; a welding galvanometer kit 3 connected to the second vertical linear motion module 22 and moving in the vertical direction; and an auxiliary welding component 4, the auxiliary welding component 4 including a mounting plate 41, a vision component 42, a ranging component 43, and a welding clamping component 44, the mounting plate 41 being connected to the first vertical linear motion module 21 and moving in the vertical direction, and the vision component 42, the ranging component 43, and the welding clamping component 44 all being connected to the mounting plate 41.

[0027] Taking Figure 1 as an example, the horizontal motion component 1 provides movement power in both directions on the horizontal plane, ensuring that the laser welding device can cover different welding positions within a preset horizontal area. The horizontal area refers to the combined area of ​​the movement range of the welding galvanometer kit 3 and the auxiliary welding component 4 when welding based on the designed workpiece dimensions of the laser welding device from a top-down perspective. The vertical motion component 2 is connected to the horizontal motion component 1 and is controlled by the horizontal motion component 1 to move within the preset horizontal area. The vertical motion component 2 includes two vertical linear motion modules, namely the first vertical linear motion module 21 and the second vertical linear motion module 22, which are used to control and drive the auxiliary welding component 4 and the welding galvanometer kit 3 to move in the vertical direction, respectively. During the operation of the laser welding device, the welding galvanometer kit 3 moves in the vertical direction to achieve precise positioning and adjustment of the beam during welding. The auxiliary welding component 4 includes a mounting plate 41, a vision component 42, a ranging component 43, and a welding clamping component 44. The mounting plate 41 is connected to the first vertical linear motion module 21 and moves in the vertical direction. The vision component 42, ranging component 43, and welding clamping component 44 are all connected to the mounting plate 41, and their height is adjusted with the movement of the mounting plate 41. The vision component 42, through the cooperation of camera 422, lens 421, and light source, captures and positions the welding location, ensuring the welding head is precisely aligned with the welding point. The ranging component 43 measures the height of the busbar, assisting the welding device in adjusting according to the slight height differences of different busbar poles, ensuring the welding head height is appropriate. The welding clamping component 44 uses a cylinder to push the clamping head, clamping the busbar to prevent incomplete welds during the welding process. The welding galvanometer kit 3, driven by the second vertical linear motion module 22, adjusts the laser focal length, achieving automatic compensation for busbars of different heights. By automatically adjusting the vertical height and visual positioning, changeover time is significantly reduced, making the laser welding device adaptable to the welding needs of various modules and more efficient. Simultaneously, the precise ranging and clamping components also improve welding quality and reduce incomplete welds.

[0028] Compared with the prior art, the laser welding device of this invention, by setting a vertical motion component 2 with a first vertical linear motion module 21 and a second vertical linear motion module 22 on the horizontal motion component 1, connects the welding galvanometer kit 3 and the auxiliary welding component 4 to the second vertical linear motion module 22 and the first vertical linear motion module 21 respectively, so that the welding galvanometer kit 3 and the auxiliary welding component 4 can move independently in the vertical direction. This allows the vision component 42, the ranging component 43 and the welding clamping component 44 mounted on the mounting plate 41 to be independently adjusted in the vertical position when changing modules during the prototyping or small-batch production stage, so as to meet the needs of rapid module changeover and thus improve production efficiency.

[0029] In one embodiment, referring to Figures 1 and 2, the vision component 42 includes a lens 421, a camera 422, a flange distance adjustment block 423, and a first-type bracket 424. The first-type bracket 424 is connected to the mounting plate 41, the lens 421 is connected to the first-type bracket 424, and the camera 422 is connected to the flange distance adjustment block 423. The flange distance adjustment block 423 is slidably disposed on the side of the first-type bracket 424 away from the mounting plate 41. The first-type bracket 424 is fixed to the mounting plate 41, serving as a support for the vision component 42 to ensure the camera 422 remains stable during adjustment, preventing image distortion caused by vibration or positional changes. The lens 421 transmits the busbar surface image to the camera 422 through an optical system. In specific use, the lens 421 is connected to a bracket via a threaded connection to achieve precise positioning, ensuring that the camera 422 captures a clear image. The camera 422 is connected to the bracket via the flange distance adjustment block 423. The camera 422 is used to capture images and perform image recognition of the welding area. Through a precise vision recognition system, it acquires the actual position of the busbar in real time and feeds this information back to the control system connected to the laser welding device for adjustment of the welding position. The flange distance adjustment block 423 is slidably mounted on the side of the first type bracket 424 away from the mounting plate 41, and has a fine-tuning function to ensure that the camera 422 can be precisely adjusted at any time during welding operations at different heights and angles. This adjustment capability allows the equipment to adapt to different modules and welding requirements, ensuring the efficient operation of the vision system. Specifically, the flange distance adjustment block 423 has two oblong holes along its left and right sides, which are countersunk holes. The long axis of the oblong holes is perpendicular. The first type bracket 424 has two threaded fixed holes aligned with the oblong holes. The user can use bolts to screw into the fixed holes through the oblong holes to press and fix the flange distance adjustment block 423 onto the first type bracket 424. When the operator needs to adjust the position of the flange distance adjustment block 423, the bolts are loosened to adjust the vertical position of the flange distance adjustment block 423. In actual welding processes, due to the height differences between different modules, the position of camera 422 needs precise adjustment. Through the sliding function of flange distance adjustment block 423, users can quickly adjust the focal length of camera 422 according to the different heights of the modules, ensuring accuracy during the welding process. The sliding of flange distance adjustment block 423 not only solves the problem of fine-tuning the position but also effectively avoids positioning errors caused by inaccurate manual adjustments during changeovers, improving the automation level of the equipment and reducing human error.

[0030] Further referring to Figures 1 and 2, the vision assembly 42 also includes a focus position monitoring element 425. The focus position monitoring element 425 is connected to the first type bracket 424, and the flange distance adjustment block 423 is slidably disposed within the monitoring range of the focus position monitoring element 425 in the vertical direction. The focus position monitoring element 425 is used to monitor the position of the flange distance adjustment block 423 in real time, and is connected to the first type bracket 424 and installed in the vision assembly 42. In specific use, the positional change of the flange distance adjustment block 423 in the vertical direction can be detected through technologies such as sensors, photoelectric devices, or encoders. Simultaneously, to facilitate intuitive observation and position recording of the flange distance adjustment block 423 by operators during use, a scale is also provided as a reference. The function of the focus position monitoring element 425 is to ensure that the camera 422 is always within the predetermined working range, avoiding positional deviation when the adjustment block slides, thereby ensuring accurate capture of the welding area by the camera 422. The focusing position monitoring element 425 covers the sliding trajectory of the flange distance adjusting block 423. Within this range, the monitoring element can accurately provide feedback on the position of the adjusting block, which is then processed by the control system. If the adjusting block moves out of the monitoring range, the system will issue a warning signal, prompting the operator to reset or correct it.

[0031] In one embodiment, referring to Figures 1 and 2, the mounting plate 41 has a first mounting area 411, with a plurality of first-type mounting holes 412 arranged in an array within the first mounting area 411. A first-type bracket 424 is connected to any of the first-type mounting holes 412 via a connector. During the manufacturing of the mounting plate 41, the first mounting area 411 is formed thereon. Within the first mounting area 411, the plurality of first-type mounting holes 412 are arranged in a specific array. These first-type mounting holes 412 are evenly distributed and precisely designed according to the intended application of the laser welding device, allowing for flexible installation of the first-type bracket 424 based on different expected processing requirements. The array arrangement design makes the installation and adjustment of the first-type bracket 424 more flexible and stable, adapting to different welding tasks and equipment configurations. The first-type bracket 424 is connected to the mounting plate 41 via a connector, which can be a bolt, snap-fit, or locking device, making the installation process of the first-type bracket 424 both simple and stable. The versatility and adjustability of the connectors allow users to quickly adjust the position and angle of the camera 422 during equipment debugging, maintenance, and replacement, thereby improving the flexibility and applicability of the equipment.

[0032] In one embodiment, referring to Figures 1 and 2, a working area bracket 46 is further provided between the ranging component 43, the welding clamping component 44, and the mounting plate 41. The ranging component 43 and the welding clamping component 44 are both located on the side of the working area bracket 46 away from the mounting plate 41. The mounting plate 41 has a second mounting area 413, which has a plurality of second-type mounting holes 414 arranged in an array. The working area bracket 46 is connected to any of the second-type mounting holes 414 via connectors. The working area bracket 46 is a support frame installed between the mounting plate 41 and the ranging component 43 and the welding clamping component 44. Its main function is to provide a stable support platform, allowing the welding clamping component 44 and the ranging component 43 to be moved away from the mounting plate 41 and held in the correct position for precise laser welding operations. The second mounting area 413 is provided on the mounting plate 41 during its manufacturing process. Within the second mounting area 413, multiple second-type mounting holes 414 are arranged in a specific array to secure the working area bracket 46. These second-type mounting holes 414 are evenly distributed and precisely engineered according to the intended application of the laser welding device, allowing for flexible installation of the working area bracket 46 based on different expected processing requirements. The working area bracket 46 is connected to the mounting plate 41 via connectors, with the specific connection method similar to that of the first-type bracket 424 described above, and therefore will not be repeated here. In particular, because the weight of the components mounted on the working bracket and the forces they experience during welding are much greater than those of the first-type bracket 424, the diameter of the second-type mounting holes 414 is larger than that of the first-type mounting holes 412. This results in a visually noticeable difference in the dimensions of the connectors used for the two types of mounting holes, facilitating the operator's differentiation between the connectors installed in the second-type mounting holes 414 and those in the first-type mounting holes 412 when disassembling or assembling them, thus avoiding installation errors caused by mixing parts.

[0033] In one embodiment, referring to Figures 1 and 2, the auxiliary welding assembly 4 further includes a dust removal assembly 45, which is connected to the working area support 46. During welding, when the laser beam irradiates the welding point, it generates a large amount of heat, causing the metal to melt and evaporate, releasing fumes. At this time, the dust removal assembly 45 needs to absorb the fumes from the welding area in real time through a suction system to prevent these harmful gases from interfering with the welding process. The fumes are purified, ensuring environmental cleanliness and welding quality. The dust removal assembly 45, installed on the working area support 46, ensures that the dust removal system is always maintained at an appropriate height and position within the working area, allowing for effective absorption and filtration of fumes. The design of the connectors makes the dust removal assembly 45 more stable, preventing loosening or displacement during operation.

[0034] In one embodiment, referring to Figures 1 and 2, the working area support 46 includes multiple sub-supports 461, the ranging component 43 includes multiple ranging units, the welding clamping component 44 includes multiple clamping units, and the dust removal component 45 includes multiple dust removal units. The ranging units, clamping units, and dust removal units are grouped and arranged in each sub-support 461. Each sub-support 461 is connected to any of the second-type mounting holes 414 via connectors, and an interval is provided between adjacent sub-supports 461. The working area support 46 is designed with multiple sub-supports 461, each sub-support 461 being connected to the second-type mounting holes 414 on the mounting plate 41 via connectors. This connection method ensures the stable installation of the sub-supports 461 and allows for quick adjustment or replacement of the sub-supports 461 as needed. The intervals between the multiple sub-supports 461 ensure that there is no interference between the components. Each sub-support 461 is equipped with a ranging unit, a welding clamping unit, and a dust removal unit. By using multiple sub-supports 461 to set up the ranging unit, welding clamping unit, and dust removal unit in groups, multiple weld points can be welded in a single clamping action, improving welding efficiency. At the same time, the multi-support design 461 also makes equipment changeover and maintenance more convenient, reduces maintenance downtime, and improves production efficiency.

[0035] In one embodiment, referring to Figures 1 and 2, the horizontal motion component 1 includes a first-axis linear motion module 11 and a second-axis linear motion module 12. The second-axis linear motion module 12 is connected to the first-axis linear motion module 11 and moves along the first axis. The vertical motion component 2 is connected to the second-axis linear motion module 12 and moves along the second axis. The first and second axes are perpendicular to each other on the same horizontal plane. The first-axis linear motion module 11 is mainly responsible for moving along the X-axis direction on the horizontal plane. The second-axis linear motion module 12 is mainly responsible for moving along the Y-axis direction on the horizontal plane. This module typically uses an electric slide drive system, which, through precision linear guides and servo motors, enables the laser welding head and other additional components to move precisely forward and backward or left and right along this axis. This design helps to achieve high-precision movement of the laser welding device in the X and Y axis directions. The first-axis linear motion module 11 and the second-axis linear motion module 12 are adjusted to work together through a linear drive system. The vertical motion component 2 is connected to the second-axis linear motion module 12 and is responsible for controlling the movement of the device in the Z-axis direction.

[0036] Further, referring to Figures 1 and 2, several height equalization blocks 13 are provided below the first axis linear motion module 11. These height equalization blocks 13 are used for connection to the welding machine. The number and arrangement of the height equalization blocks 13 below the first axis linear motion module 11 are determined according to the size and structure of the welding machine. The height equalization blocks 13 are securely connected to the welding machine using bolts or other connection methods, ensuring a smooth connection between the machine and the motion module. During the welding process, the precise movement of the first axis linear motion module 11 directly affects the welding quality. The presence of the height equalization blocks 13 ensures that the height between the first axis linear motion module 11 and the welding machine remains consistent, avoiding instability caused by imbalance or vibration. This provides strong support for precise control during the welding process.

[0037] This invention also provides a laser welding device equipped with the laser welding apparatus described in this embodiment. Compared to other laser welding devices in the prior art, this laser welding device can significantly reduce changeover time by automatically adjusting vertical height and visual positioning, adapting to the welding needs of various modules, thereby achieving higher work efficiency in prototyping or small-batch production stages.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
