Description

Technical Field

[0002] The mobile single-arm laser welding machine is an industrial device that integrates high-precision laser welding technology with a flexible robotic arm structure. Its core consists of a laser generator, fiber optic transmission system, multi-joint robotic arm, and CNC module. A movable base allows for rapid adjustment of the working area. The equipment adopts a single cantilever design, ensuring a wide welding range while also considering spatial adaptability and ease of deployment. It is particularly suitable for in-situ welding of large and medium-sized workpieces in fields such as automotive manufacturing and aerospace.

[0003] Currently, during the welding process, the frequent movement of the robotic arm can cause the power cord, air hose, and signal line connected to the welding torch to become tangled, twisted, or even worn, thus limiting the range of motion or affecting signal transmission.

[0029] Example 1 Reference Figures 1-7 As a first embodiment of the present invention, a movable single-arm laser welding machine is provided, the device comprising: The support mechanism 100 includes a control box 110 and casters 120 fixedly installed at the bottom of the control box 110; The support management mechanism 200 includes a fixed base 210 fixedly installed on the outside of the control box 110, a support column 220 hinged to the top of the fixed base 210, an elastic buffer assembly 230 disposed at the top of the support column 220, and a connecting rod 240 hinged to the outside of the elastic buffer assembly 230. And, a welding mechanism 300 is installed on top of the control box 110.

[0030] The supporting mechanism 100 adopts a modular design, and the control box 110 integrates the control system, power unit, and cooling system into one unit. This compact layout improves space utilization. The casters 120 adopt a dual braking system design, which ensures both flexibility during movement and quick locking of position.

[0036] Among them, the ring 261 adopts a split structure, which facilitates quick maintenance and replacement. The ball 263 inside the groove block 262 is made of ceramic material, which ensures the smoothness of the sliding process. The precise fit between the threaded seat 264 and the threaded rod 265 achieves micron-level precision in height adjustment. The elastic inner lining design of the support ring 266 protects the air tube 370 and ensures reliable fixation, thereby improving work efficiency.

[0037] Furthermore, the support mechanism 100 also includes anti-tipping outriggers 130 fixedly installed at the bottom of the control box 110, and a worktable 140 fixedly installed at the top of the control box 110.

[0038] Among them, the improved design of the bearing mechanism 100 enhances the overall performance of the equipment; the anti-tipping outriggers 130 adopt a hydraulic locking system, which can quickly achieve stable support for the equipment; the anti-slip surface treatment of the worktable 140 ensures the stability of workpiece placement; and the optimized human-machine interface design of the control box 110 improves the ease of operation, enabling the equipment to maintain excellent stability under complex working conditions. At the same time, it provides operators with a more convenient and comfortable working environment, improving the overall efficiency and quality of welding operations.

[0039] When using, In summary, the load-bearing mechanism 100 adopts a combination design of control box 110 and casters 120 to ensure both the flexibility of equipment movement and operational stability. The support management mechanism 200 effectively absorbs mechanical vibration and optimizes pipeline layout through the synergistic effect of elastic buffer component 230 and hanging component 260. The welding mechanism 300 uses a multi-joint robotic arm 330 in conjunction with anti-splash component 340 and air-blowing cleaning component 360 to expand the working range while ensuring welding quality and equipment maintenance convenience. The addition of anti-tipping outriggers 130 and worktable 140 further enhances the safety and ease of operation of the equipment, improves welding accuracy, work efficiency and equipment reliability, and solves the problems of inconvenient movement, large vibration and difficult maintenance of traditional welding equipment.

[0040] Example 2 Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it provides a welding mechanism 300 that integrates high-precision robotic arm movement, dynamic spatter protection and air blowing cleaning, thereby optimizing equipment stability and work efficiency.

[0041] Furthermore, the welding mechanism 300 includes a positioning seat 310 fixedly mounted on the top of the control box 110, a transverse guide rail 320 hinged to the top of the positioning seat 310, a multi-joint robotic arm 330 hinged to the outside of the transverse guide rail 320, and a splash guard assembly 340 disposed on the outside of the multi-joint robotic arm 330.

[0042] Among them, the positioning seat 310 ensures the reference stability of the movement of the multi-joint robotic arm 330, the linear guiding system of the transverse guide rail 320 enables backlash-free movement and ensures the accuracy of the welding path, the optimized design of the multi-joint robotic arm 330 enables it to achieve a larger working range while maintaining rigidity, and the adjustable design of the splash guard 340 protects the core components of the equipment without obstructing the operator's line of sight.

[0043] Furthermore, the welding mechanism 300 also includes a laser welding gun 350 fixedly installed at the end of the multi-joint robotic arm 330, an air blowing cleaning assembly 360 disposed on the outside of the laser welding gun 350, an air pipe 370 fixedly installed on the outside of the air blowing cleaning assembly 360, and a filter 380 fixedly installed in the inner cavity of the control box 110. One end of the air pipe 370 is fixedly connected to the outside of the filter 380 and they are interconnected. The air pipe 370 is movably sleeved in the inner cavity of the support ring 266.

[0044] Among them, the multi-point airflow control system of the air blowing cleaning component 360 can accurately remove contaminants in the welding area, the filter 380 ensures the cleanliness of the air source, the flexible connection design of the air tube 370 ensures smooth airflow without restricting the movement of the multi-joint robotic arm 330, and the guiding effect of the support ring 266 makes the pipeline layout more standardized, effectively solving the problem of spatter accumulation during laser welding, protecting optical components, ensuring the stability of welding quality, and reducing the frequency of equipment maintenance.

[0045] Furthermore, the splash-proof assembly 340 includes a limiting groove 341 fixedly installed on the outside of the multi-joint robotic arm 330, a locking strip 342 movably locked in the inner cavity of the limiting groove 341, a protective shell 343 fixedly installed on the outside of the locking strip 342, and a splash-proof baffle 345 fixedly installed on the outside of the protective shell 343.

[0046] Among them, the design of the anti-splash component 340 reflects the balance between functionality and practicality. The precision machining of the limiting groove 341 ensures the movement accuracy of the sliding parts. The quick locking mechanism of the locking strip 342 facilitates the quick positioning of the protective shell 343. The protective shell 343 is made of high-temperature resistant transparent material, taking into account both the protective effect and the operational observation requirements. The angle adjustable design of the anti-splash baffle 345 allows it to adapt to the protection requirements of different welding positions, effectively solving the problem of traditional welding machine protective devices affecting the operator's line of sight. While ensuring the protective effect, it greatly improves the ease of operation.

[0047] Furthermore, the air blowing cleaning assembly 360 includes a support shell 361 fixedly installed on the outside of the laser welding gun 350, a connecting pipe 362 fixedly installed in the inner cavity of the support shell 361, a slot 363 fixedly installed on the bottom of the support shell 361, an air nozzle 364 movably engaged in the inner cavity of the slot 363, a slot 365 opened on the outside of the air nozzle 364, a clamping sleeve 366 movably engaged in the bottom of the slot 363, and a magnetic suction block 367 fixedly installed on the inner side of the clamping sleeve 366, the magnetic suction block 367 being movably engaged in the inner cavity of the slot 365.

[0048] Among them, the design of the air-blowing cleaning component 360 represents a major technological breakthrough. The streamlined design of the support shell 361 optimizes the airflow path, and the unique structure of the connecting pipe 362 achieves balanced airflow distribution. The quick-connect mechanism between the slot sleeve 363 and the air nozzle 364 makes replacement operations more convenient. The cooperative design of the slot 365 and the magnetic card block 367 ensures reliable connection while facilitating disassembly. The elastic structure of the clamping sleeve 366 provides appropriate clamping force, solving the problem of cumbersome air nozzle replacement in traditional welding machines, making maintenance work more efficient, and ensuring the continuous and stable operation of the equipment.

[0049] During use, the robotic arm 330 adjusts the welding position via the transverse guide rail 320, the anti-spatter component 340 adjusts the protection range synchronously, and when the laser welding gun 350 is operating, the air blowing cleaning component 360 continuously blows away the spatter, the filter 380 ensures a clean air source, and the pipeline moves freely with the robotic arm under the guidance of the support ring 266. The protective shell 343 and the anti-spatter baffle 345 dynamically protect key components, achieving efficient welding and automatic cleaning in one.

[0050] In summary, the precise cooperation between the positioning seat 310 and the transverse guide rail 320 ensures the baseline stability of the robotic arm's movement. The adjustable design of the anti-splash component 340 effectively blocks splashes and maintains a clear operating view. The air-blowing cleaning component 360, combined with the filter 380, removes contaminants in real time. The pipelines are arranged in a standardized manner through the support ring 266 to avoid tangling. The overall structure improves welding accuracy, equipment reliability, and ease of maintenance, and solves the problem of limited movement caused by splash accumulation and cable interference in traditional welding machines.

S2: Adjust the angle between the support column 220 and the connecting rod 240 so that the multi-joint robotic arm 330 is in the optimal working range. Use the elastic buffer component 230 to absorb the vibration during the movement of the robotic arm and extend the lateral movement stroke of the robotic arm through the transverse guide rail 320. S3: Start the laser welding gun 350, adjust the anti-spatter baffle 345 of the anti-spatter component 340 to the weld point shielding position. During the welding process, the air blowing cleaning component 360 sprays air through the air nozzle 364 to remove spatter around the welding gun. If the air nozzle 364 needs to be replaced, press the clamping sleeve 366 to make the magnetic card block 367 disengage from the slot 365 for quick disassembly and assembly. S4: After welding is completed, reset the robotic arm to the initial position, retract the anti-tipping outriggers 130, check the elasticity of the reset spring 233 and the buffer baffle 236, clean the spatter accumulated inside the protective shell 343, disassemble the air pipe 370 and store it in the ring 261 of the hanging component 260 to avoid cable mess.

The movable single-arm laser welding machine according to claim 8, characterized in that: The support mechanism (100) also includes an anti-tipping outrigger (130) fixedly installed at the bottom of the control box (110) and a worktable (140) fixedly installed at the top of the control box (110).

10. A method of use, characterized in that: The movable single-arm laser welding machine, including any one of claims 1 to 9, comprises the following steps: S1: Move the welding machine to the target work position using the casters (120), unfold the anti-tipping outriggers (130) and adjust them to be level to ensure the stability of the load-bearing mechanism (100), and fix the air pipe (370) with the support ring (266) to avoid pipeline dragging and interference; S2: Adjust the angle between the support column (220) and the connecting rod (240) to put the multi-joint robotic arm (330) in the optimal working range, use the elastic buffer component (230) to absorb the vibration during the movement of the robotic arm, and extend the lateral movement stroke of the robotic arm through the transverse guide rail (320). S3: Start the laser welding gun (350), adjust the anti-spatter baffle (345) of the anti-spatter assembly (340) to the welding point shielding position. During the welding process, the air blowing cleaning assembly (360) sprays air through the air nozzle (364) to remove the spatter around the welding gun. If the air nozzle (364) needs to be replaced, press the clamping sleeve (366) to make the magnetic card block (367) disengage from the card slot (365) for quick disassembly and assembly. S4: After welding is completed, reset the robotic arm to the initial position, retract the anti-tipping outriggers (130), check the elasticity of the reset spring (233) and the buffer plate (236), clean the spatter accumulated in the protective shell (343), disassemble the air pipe (370) and store it in the ring (261) of the hanging component (260) to avoid cable mess.
