In this embodiment, through the coordinated work of the support column 18, the first motor 25, the helical rack 24, the linear guide rail 26, the linear module 19, and the aluminum profile assembly 21, the position recognition component 4 can achieve precise movement and positioning of the 3D camera 20 in space. This design not only enhances the flexibility and coverage of the 3D camera 20, enabling it to scan and identify materials from different angles and positions, but also ensures the stability and repeatability of camera movement through high-precision motion control via the linear guide 26 and linear module 19. Furthermore, the transmission design of the first motor 25 and the helical rack 24 provides reliable driving force and precise speed control, further improving the accuracy and efficiency of position recognition. This structural design significantly enhances the accuracy and reliability of the welding system's material position recognition, providing strong support for achieving high-precision automated welding.

[0040] Specifically, when the first motor 25 rotates, it drives the linear module 19 to perform precise linear motion along the linear guide 26 in the transverse section through the meshing transmission of the gear 36 and the helical rack 24. An aluminum profile assembly 21 is mounted on the linear module 19, and the 3D camera 20 is fixed to the aluminum profile assembly 21. Therefore, when the linear module 19 moves, the 3D camera 20 also moves, enabling scanning and position recognition of the material from different positions and angles. This structural design allows the 3D camera 20 to flexibly adjust its position within a set area, achieving high-precision positioning and tracking of the material, providing accurate coordinate information for subsequent welding operations, and ensuring the accuracy and reliability of the welding process.

By setting the lubricator in the vertical section, centralized management of the lubrication system of the entire position recognition component 4 can be achieved, ensuring that the lubricant can be evenly and continuously distributed to each moving part. This design not only improves the maintenance efficiency of the system and reduces maintenance costs, but also enhances the reliability and operational stability of the system, thus providing a strong guarantee for high-precision position recognition.

[0042] In one embodiment, the first lubricator 22 can be an automatic lubrication device, which includes an oil reservoir and a precision metering pump. This device can automatically and accurately deliver lubricating oil to key moving parts on the support column 18, such as the linear guide 26, helical rack 24, and gear 36, according to preset time intervals or movement frequencies. This automatic lubrication system not only improves lubrication efficiency and reduces the frequency and cost of manual maintenance, but also ensures uniform distribution of lubricating oil, effectively reducing friction between components and wear, thereby extending the service life of the equipment and improving the operational stability of the system. Furthermore, the automatic lubricator can also be equipped with an oil level sensor and an alarm system to monitor the remaining amount of lubricating oil in real time, ensuring the normal operation of the lubrication system.

[0043] In one embodiment, such as Figure 4 As shown, the position recognition component 4 also includes a bellows cover 23, which is disposed on the transverse section of the supporting column 18 and covers the linear guide rail 26. In this embodiment, the bellows cover 23 can effectively protect the linear guide rail 26 from contamination and damage caused by dust, welding slag, oil, and other impurities. The linear guide rail 26 is a key moving component in the position recognition component 4, and its accuracy and performance directly affect the positioning accuracy of the 3D camera 20. The flexible design of the bellows cover 23 allows it to extend and retract freely when the linear guide rail 26 moves, while providing reliable protection to ensure that the guide rail is always clean and in good working condition. This protective measure not only extends the service life of the linear guide rail 26, but also reduces system failures caused by guide rail wear or jamming, improves the reliability and stability of the entire position recognition component 4, and thus provides a strong guarantee for high-precision welding positioning.

In this embodiment, the drive assembly 30 encloses the motor and other transmission components through the protective cover 33, effectively preventing dust, welding slag, and other impurities from entering, extending the service life of the components, and improving the reliability of the system. The second motor 34 transmits power to the limit switch 31 through the coupling 38, transmission shaft 37, gear 36, and chain 35, achieving precise control of the movement of the lower material cart 28. This transmission method not only provides stable power output but also achieves large torque transmission through the meshing of the chain 35 and gear 36, ensuring that the lower material cart 28 can move smoothly and accurately. In addition, this design facilitates maintenance and component replacement, further improving the system's stability and maintainability.

[0048] Specifically, the second motor 34 is installed inside the protective cover 33 and connected to the drive shaft 37 via a coupling 38. When the second motor 34 starts, its power is transmitted to the drive shaft 37 through the coupling 38, thereby driving the gear 36 mounted on the drive shaft 37 to rotate. The rotation of the gear 36 transmits power through the chain 35 meshing with it, and the other end of the chain 35 is connected to the limit switch 31. When the chain 35 moves, the limit switch 31 controls the movement of the lower material cart 28 according to a preset position signal, causing it to move along a predetermined trajectory and position on the guide assembly 29. This transmission method ensures precise movement control of the lower material cart 28, while the presence of the protective cover 33 effectively prevents external impurities from interfering with the transmission components, improving the stability and reliability of the system.

[0049] In one embodiment, such as Figure 1As shown, the laser intelligent welding system for anti-collision beams used in electric vehicle production also includes a waste collection box 5 for collecting waste during the laser welding process, which is located on the main frame. In this embodiment, the waste collection box 5 is used to collect waste generated during laser welding, a design that offers several advantages. First, it effectively keeps the work area clean, preventing safety hazards and equipment damage caused by scattered waste. Second, centralized waste collection facilitates subsequent unified processing, reducing the frequency and labor intensity of manual cleaning and improving production efficiency. Furthermore, the waste collection box 5 helps maintain the stable operation of the welding system, reducing welding quality problems that may be caused by waste accumulation, thereby ensuring the smooth progress of the welding process and the reliability of the welding quality.
