The auxiliary structure 14 is arranged on the side of the sliding seat structure 12; and a dust suction device 2, which includes an eddy current suction nozzle 21, a fixing plate 22, a covering plate 23, and a main unit 24. The fixing plate 22 is fixedly arranged on the sliding seat structure 12. The eddy current suction nozzle 21 is fixedly arranged at one end of the fixing plate 22. The main unit 24 is arranged on one side of the fixing plate 22. The covering plate 23 is buckled on the main unit 24 and fixedly connected to the fixing plate 22. The main unit 24 is used to control the eddy current suction nozzle 21.

[0024] In the above embodiment, for the mobile device 1 part, the fixed base 11 is firmly installed on the machine tool and serves as the support foundation of the entire system. The slide structure 12 can slide along the direction set by the fixed base 11. The linear motor 13 serves as the power source and directly drives the slide structure 12 to perform linear movement. The auxiliary structure 14 is installed on the side of the slide structure 12, which not only enhances the linear guiding accuracy of the slide during movement but also effectively compensates for the vibration that may occur during high-speed movement or operation of the slide through its structural characteristics, ensuring smooth movement. For the dust suction device 2, the fixing plate 22 is connected to the slide structure 12 and moves together with the slide to achieve flexible adjustment of the dust suction position. The eddy current suction nozzle 21 is fixedly installed at the front end of the fixing plate 22 and uses the eddy current principle to efficiently adsorb the dust generated during the welding process. The main unit 24 is integrated at the rear side of the fixing plate 22 and is firmly encapsulated by the cover plate 23, which not only protects the internal components but also facilitates overall installation and maintenance. The control system is integrated inside the main unit 24 and is responsible for regulating the working state of the eddy current suction nozzle 21 to ensure the synchronization of the dust suction efficiency and the welding operation. The overall structure is designed compactly with clear functions, achieving efficient dust removal during the laser welding process.

[0025] Please refer to Figures 1 to 6 , in another embodiment, chutes 111 are provided on both sides of the fixed base 11. The slide structure 12 includes a sliding bottom plate 121, a connecting plate 122, a retaining plate 123, and a support member 124. The sliding bottom plate 121 is provided with sliders 125 that match the chutes 111. The connecting plate 122 is vertically arranged at both ends of the sliding bottom plate 121. The retaining plate 123 is fixedly connected to the connecting plate 122. The linear motor 13 is located between the retaining plate 123 and the connecting plate 122. The retaining plate 123 and the connecting plate 122 are arranged in alignment. The support member 124 is fixedly arranged at both ends of the retaining plate 123.

[0026] In the above embodiment, the slider structure 12 is composed of a sliding bottom plate 121, a connecting plate 122, a retaining plate 123 and a support member 124, forming a stable and flexible motion unit. The slider 125 installed at the bottom of the sliding bottom plate 121 is in close fit with the sliding groove 111 of the fixed seat 11, ensuring the smooth sliding of the slider structure 12 in the horizontal direction. The connecting plates 122 are vertically installed at both ends of the sliding bottom plate 121, enhancing the overall rigidity of the slider structure 12 and serving as the installation base for the retaining plate 123 and the support member 124. The retaining plate 123 is arranged opposite to the connecting plate 122, and the linear motor 13 is located between the retaining plate 123 and the connecting plate 122. A pulley is provided on the slider 125, and the linear motor 13 drives the pulley to achieve the precise linear movement of the slider structure 12. At the same time, the linear motor 13 is fixedly arranged on the sliding bottom plate 121, and the sliding bottom plate 121 is directly connected to the fixed seat 11, with a relatively stable center of gravity, which can effectively reduce the vibration generated by the linear motor 13. The support members 124 are fixed at both ends of the retaining plate 123, providing additional support force for the entire slider structure 12 and enhancing its stability under high-speed or heavy-load conditions. This structural design principle ensures that the slider structure 12 can achieve efficient and precise linear sliding under the guidance of the fixed seat 11, meeting the requirement of flexible adjustment of the position of the dust suction nozzle during the laser welding process.

[0027] Please refer to Figures 1 to 6 , in another embodiment, the support member 124 is provided in an axe shape, and a square through hole is provided on the axe surface of the support member 124.

[0028] In the above embodiment, the overall weight of the support member 124 is reduced, which is beneficial to reducing the inertial force during the movement process and improving the accuracy of movement.

[0029] Please refer to Figures 1 to 6 , in another embodiment, the auxiliary structure 14 includes a drag chain 141 and a limit slider 142. The drag chain 141 is slidably arranged on the limit slider 142. The drag chain 141 is connected to the side surface of the support member 124 through a reinforcing rib, and the limit slider 142 is fixedly arranged on the machine tool.

[0030] In the above embodiment, the drag chain 141, as a flexible connecting member, can accommodate and protect auxiliary components such as cables and air pipes inside, preventing them from being pulled or damaged during the movement of the sliding seat. The drag chain 141 is slidably arranged on the limiting sliding member 142, and the latter is firmly fixed on the machine tool, providing a clear sliding path and limiting boundary for the drag chain 141. By using the reinforcing ribs to firmly connect the drag chain 141 with the side surface of the support member 124, not only is it ensured that the drag chain 141 moves synchronously with the sliding seat structure 12, but also the flexible characteristics of the drag chain 141 are utilized to absorb and buffer the vibrations that may occur during the movement of the sliding seat structure 12 to a certain extent. At the same time, the limiting sliding member 142 precisely guides the sliding of the drag chain 141 to prevent it from deviating from the predetermined path, thereby ensuring the accuracy and stability of the linear sliding of the sliding seat structure 12.

[0031] Please refer to Figures 1 to 6 , in another embodiment, two eddy current suction nozzles 21 are provided, and the two eddy current suction nozzles 21 are arranged in series linearly.

[0032] In the above embodiment, the dust suction range and efficiency are expanded by increasing the dust suction points. The eddy current suction nozzles 21 arranged in series can act on both sides or front and back of the welding area simultaneously, forming a wider dust suction coverage area, and effectively capturing the dust and spatter generated during the welding process.

[0033] Please refer to Figures 1 to 6 , in another embodiment, a retaining member 25 is further included, the retaining member 25 is fixedly arranged on the fixing plate 22, and the handle of the eddy current suction nozzle 21 is clamped to the retaining member 25.

[0034] In the above embodiment, the shape of the handle part of the eddy current suction nozzle 21 matches the card slot or buckle of the retaining member 25, and it is firmly connected to the retaining member 25 by directly inserting or rotating and engaging, thereby realizing the fixed installation of the eddy current suction nozzle 21 on the fixing plate 22. This structure ensures the stability and detachability of the eddy current suction nozzle 21 during use, facilitating maintenance and replacement.
