[0002] With the development of the manufacturing industry, the production scale and complexity of products are constantly increasing. In laser cutting, the traditional manual feeding method is inefficient, lacks precision, and cannot meet the requirements of large-scale, high-quality production. For example, in industries such as automobile manufacturing and electronic equipment production, a large number of metal sheets and pipes need to be laser cut with high precision. Manual feeding cannot guarantee the speed and accuracy of feeding, thus affecting the efficiency of the entire production process and the quality of products.

[0003] Existing automatic feeding mechanisms for laser cutting lack an adaptive adjustment structure, making it difficult to accurately position the clamping device according to the material width. The material is prone to shifting or tilting during feeding, resulting in a large deviation between the laser cutting trajectory and the design drawings, leading to a high scrap rate. This is especially true for narrow or irregularly shaped materials, where the positioning error is more pronounced. Therefore, improvements are needed to address these issues. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses an automatic laser cutting feeding mechanism, comprising a frame 1 and a controller 2 installed on one side of the rear end of the frame 1. A support platform 3 is installed at the front end inside the frame 1, and a positioning frame 4 is horizontally installed inside the frame 1. Support platforms 17 are slidably connected to both ends of the top surface of the frame 1. A first sliding seat 18 is slidably connected laterally to the upper end of the support platform 17, and a second sliding seat 19 is slidably connected vertically to the first sliding seat 18. A laser cutting device is installed at the lower end of the second sliding seat 19. A positioning component is installed inside the positioning frame 4. The frame 1 provides overall rigid support, ensuring the structural stability of the equipment. The controller 2 facilitates automated control, coordinating precise cooperation among various moving parts. The support platform 3 supports the front end of the material to be cut, reducing material deformation due to suspension. The positioning frame 4 serves as the subsequent positioning component. The system provides an installation reference to ensure positioning accuracy; the longitudinal processing range of the laser cutting equipment is expanded by the longitudinal sliding of the support platform 17 along the top surface of the frame 1; the three-dimensional spatial positioning of the laser cutting equipment is achieved by the lateral sliding of the first sliding seat 18 and the vertical sliding of the second sliding seat 19, adapting to the needs of complex cutting paths; the positioning components include front and rear positioning shafts 5 horizontally installed inside the positioning frame 4, with electric push cylinders installed at both ends of the positioning shafts 5, and an electric slide table 6 longitudinally installed at the output end of the electric push cylinder on the same side. The electric slide table 6 is slidably connected to the front and rear positioning shafts 5, and a moving clamp 7 is slidably connected to the electric slide table 6; the electric slide table 6 facilitates the lateral movement of the moving clamp 7 to achieve precise positioning and clamping of the material; the moving clamp 7 facilitates the provision of stable clamping force to prevent material displacement during cutting and improve cutting accuracy.

[0020] In this invention, a support frame 9 is horizontally installed inside the positioning frame 4, positioned between two electric slides 6. Multiple equidistant support plates 10 are horizontally installed inside the support frame 9, and multiple equidistant support components are horizontally arranged inside the support frame 9, with each support component positioned between adjacent support plates 10. A positioning shaft 5 provides a guide rail for the longitudinal sliding of the electric slides 6, ensuring movement accuracy. An electric cylinder drives the electric slides 6 to move along the positioning shaft 5, automatically adjusting the spacing of the moving clamps 7 according to the material width, improving versatility. The support frame 9 facilitates the installation of the support plates 10. The support plates 10 facilitate the provision of a continuous support surface, reducing bending deformation of the material due to its own weight. The support components include a connecting frame 11 installed inside the support frame 9. A cylinder 12 is installed on the front end face of the connecting frame 11. The upper end of the output shaft of the cylinder 12 is connected to a U-shaped seat 13, and a roller 14 is rotatably connected to the U-shaped seat 13. A baffle 15 is hinged to the internal rear end face. The baffle 15 has an L-shaped cross-section, and a roller 16 is installed at the hinge point between the baffle 15 and the connecting frame 11. The roller 16 is located at the lower end of the U-shaped seat 13. The cylinder 12 facilitates the lifting and lowering of the U-shaped seat 13, thereby adjusting the height of the roller 14 to accommodate materials of different thicknesses. The roller 14 facilitates the rolling support of materials, reduces feeding friction, and improves feeding smoothness. The baffle 15 and roller 16 facilitate the shielding of the roller 14. The connecting frame 11 facilitates the installation of the cylinder 12 and the baffle 15. Guide rails are installed on both sides of the top surface of the support platform 3, and fixing clamps 8 are installed on both sides of the rear end of the top surface of the support platform 3. An installation groove is opened in the middle of the rear end of the top surface of the support platform 3, and the roller 14 is rotatably connected in the installation groove. The fixing clamps 8 facilitate the fixing of the rear end of the material, and work in conjunction with the moving clamps 7 to achieve reliable clamping of the material throughout its entire stroke. The roller 14 facilitates the auxiliary feeding of the rear end of the material, reduces frictional resistance, and improves feeding stability.

[0021] Working Principle: In the use of this utility model, firstly, connect all electrical equipment with wires and power it on. Then, place the workpiece on the support platform 3. Next, adjust the distance between the two electric slides 6 at both ends using an electric push cylinder. Adjust the distance between the two electric slides 6 according to the width of the workpiece. Then, clamp the two ends of the workpiece with the moving clamps 7. Then, start the electric slides 6 to control the two moving clamps 7 to move to the rear end, thereby controlling the workpiece to move into the device. When the workpiece moves inward, start the cylinder 12 to control the roller 14 to move upward, thereby hitting the baffle 15 and exposing the roller 14 to support the workpiece. When the workpiece moves to the designated position, start the cylinder 12 to control the roller 14 to descend. At this time, the U-shaped seat 13 hits the roller 16, thereby blocking the roller 14 with the baffle 15. At this time, the support plate 10 supports the workpiece. Then, start the linear motor installed inside the support platform 17, the first sliding seat 18 and the second sliding seat 19 to control the laser cutting equipment to move and cut the workpiece. After the cutting is completed, turn off the power to all electrical equipment.
