Description

Technical Field

[0002] With the rapid development of industries such as automotive and shipbuilding, the cutting of special-shaped sheet metal in these industries is showing a trend towards large-scale, diversified, and high-precision production.

Preferably, multiple laser cutting robots 4 are provided on both sides of the workbench 1. Each laser cutting robot can perform a specific laser cutting process. In this way, the material 9 is subjected to multiple laser cutting processes in the workbench, achieving high-precision cutting of the material 9.

[0053] The discharge track 3 is connected to the worktable 1. The discharge track 3 is equipped with a robot arm, which is used to transfer the material 9 from the worktable 1 to the discharge track 3. When the material 9 has completed all laser cutting processes on the worktable, and the material 9 is transported to the position connected to the discharge track 3 in the worktable 1, the robot arm transfers the material 9 from the worktable 1 to the discharge track 3, thereby realizing the discharge and transportation of the material 9.

[0054] A visual recognition device is installed in the area where the discharge track 3 connects with the workbench 1. The visual recognition device is used to visually transfer the weld of the material 9 on the discharge track 3.

[0055] At least one laser cutting robot 4 is provided on one side of the discharge track 3. The laser cutting robot 4 is used to perform laser cutting on the material 9 according to the weld seam of the material 9. In order to improve the laser cutting accuracy of the material 9, the weld seam of the material 9 transferred to the discharge track 3 is identified by a vision recognition device, so that the laser cutting robot matched with the discharge track 3 can perform more precise laser cutting on the material 9 and improve the accuracy of laser cutting of the material.

[0056] Preferably, the feeding track 2 includes a plurality of first legs 21 arranged at intervals along a straight line; each first leg 21 is provided with a first track 22, and the first track 22 is provided with a first conveyor belt 23, which is used to transport the material 9 on the first track 22.

[0060] The rotating base 41 is capable of rotating 360° in the horizontal direction;

[0061] The multi-degree-of-freedom robotic arm 42, mounted on the rotating base 41, is capable of moving in three mutually perpendicular directions and rotating in the pitch, yaw, and roll directions.

[0062] A binocular machine vision device 43 and a laser cutting device 44 are installed at the free end of the multi-degree-of-freedom robotic arm 42.

[0063] The rotating base 41 of the laser cutting robot 4 can drive the multi-degree-of-freedom robotic arm 41 to rotate 360° in the horizontal direction, allowing the multi-degree-of-freedom robotic arm 41 to switch between entering and exiting states relative to the worktable 1. Furthermore, the multi-degree-of-freedom robotic arm 42 can move freely along the X, Y, and Z axes in three-dimensional space, and rotate independently in the pitch, yaw, and roll directions, thereby driving the six-degree-of-freedom motion of the binocular machine vision device 43 and the laser cutting device 44. This ensures that the binocular machine vision device 43 and the laser cutting device 44 aim at specific positions on the material 9 for imaging and cutting, improving the accuracy of laser cutting.

[0064] Preferably, the binocular machine vision device 43 includes two cameras; the imaging optical axes of the two cameras form an angle, ranging from 60° to 150°; the laser cutting device 44 includes a pulsed laser. The binocular machine vision device 43 enables binocular imaging and recognition of the material 9, obtaining the three-dimensional shape features of the material 9's surface, thus improving the accuracy of laser cutting.

[0065] Preferably, please refer to Figure 3The laser cutting robot 4 also includes a slider 45 and a ground rail 46; the ground rail 46 is parallel to the worktable 1; a rotating base 41 is mounted on the slider 45; the slider 45 engages with the ground rail 46, and the slider 45 can slide back and forth along the ground rail 46. In order to expand the range of motion of the laser cutting robot 4, the slider 45 and the ground rail 46 work together to drive the laser cutting robot 4 to slide back and forth along the ground rail 46, so that the laser cutting robot 4 can perform laser cutting on a larger area of ​​material 9 on the worktable 1.

The anti-arc light enclosures 5 can be made of polycarbonate. The semi-enclosed space 7 formed by the anti-arc light enclosures 5 provides a relatively safe and isolated working environment for the workstation, preventing the arc light generated by the laser cutting robots 4 during operation from leaking into the external environment, thus improving the operational safety of the workstation.

[0067] Preferably, it also includes several cooling fans 7; all cooling fans 7 are respectively arranged in different positions inside the semi-enclosed space. By distributing multiple cooling fans 7 inside the semi-enclosed space 7, the cooling airflow output by the multiple cooling fans 7 forms a convection circulation inside the semi-enclosed space 7, effectively dissipating the heat generated by the laser cutting robot 4 during operation, so that the material 9 is cooled down quickly after being laser cut.
