[0002] Laser cutting technology, as a high-precision and high-efficiency modern processing method, has been widely used in the field of sheet metal manufacturing, such as the production of sheet metal components like air conditioner housings. When a laser cutting machine is working, the sheet-like workpiece to be processed needs to be precisely placed on its worktable. Therefore, the performance of the automated loading mechanism directly affects the production efficiency, processing accuracy, and automation level of the entire laser cutting unit. Currently, common laser cutting machine loading mechanisms mostly use Cartesian coordinate robots or articulated robots in conjunction with suction cup devices to achieve workpiece handling. Specifically, it typically includes a conveyor mechanism located adjacent to the worktable, and a handling mechanism for transferring the workpiece from the conveyor mechanism to the worktable.
[0003] In the process of developing this utility model, the inventors discovered that the existing technology has at least the following major problems and defects: insufficient motion flexibility and limited adaptability, lack of positioning accuracy and correction capability, and a single structural function that makes it difficult to achieve fine adjustment. Therefore, there is an urgent need in the field for a new type of laser cutting machine feeding mechanism that can overcome the above-mentioned defects of the existing technology, possess higher motion flexibility, stronger environmental adaptability, and more accurate positioning and correction functions, so as to meet the needs of modern smart factories for flexible manufacturing and high-precision processing. Utility Model Content
[0004] Therefore, it is necessary to provide a new type of laser cutting machine feeding mechanism to address the technical problem of insufficient flexibility in existing laser cutting machine feeding mechanisms.
[0005] A laser cutting machine feeding mechanism includes a worktable, a conveying mechanism, and a suction mechanism. The worktable serves as a material support structure for the laser cutting machine to hold the plate-shaped workpiece to be cut. The conveying mechanism is located on the adjacent side of the worktable, and the suction mechanism is located between the worktable and the conveying mechanism.
[0006] The material suction mechanism includes a first drive assembly, a second drive assembly, a third drive assembly, a fourth drive assembly, and a material suction assembly; the first drive assembly is slidably mounted on the side edge of the worktable; the second drive assembly is movably mounted on the output end of the first drive assembly; the third drive assembly is movably mounted on the output end of the second drive assembly; the fourth drive assembly is movably mounted on the output end of the third drive assembly; and the material suction assembly is mounted on the output end of the fourth drive assembly.
[0007] The material suction mechanism also includes a rotary drive unit, which is disposed between the first drive assembly and the second drive assembly. The rotary drive unit is installed at the output end of the first drive assembly, and the second drive assembly is movably installed at the output end of the rotary drive unit.
[0008] In one embodiment, the first drive assembly described above extends along the length of the worktable and is mounted on the side surface of the worktable facing the conveying mechanism.
[0009] In one embodiment, the first drive component described above uses a ball screw module combined with a servo motor to form a linear slide module, thereby meeting the long stroke positioning requirements.
[0010] In one embodiment, the aforementioned rotary drive unit uses a hollow rotary platform in conjunction with a servo motor to form a rotary drive mechanism.
[0011] In one embodiment, the bottom surface of the rotary drive unit is connected to the top surface of the output end of the first drive assembly, and the output end of the rotary drive unit is positioned facing the top side.
[0012] In one embodiment, the second drive component described above is disposed parallel to the top side surface of the worktable at the output end of the rotary drive unit.
[0013] In one embodiment, the second drive component described above uses a lightweight aluminum alloy ball screw module combined with a servo motor to form a linear slide module.
[0014] In one embodiment, the top surface of the vertical stage of the third drive component is disposed at the output end of the second drive component.
[0015] In one embodiment, the aforementioned third drive component employs a servo electric cylinder with a brake.
[0016] In one embodiment, the fourth drive component is disposed parallel to the top side surface of the worktable at the output end of the third drive component.

[0023] In one embodiment, a material guiding mechanism is provided at each end of the workbench.
[0024] The aforementioned laser cutting machine's feeding mechanism, through the close spatial connection of the conveying mechanism, suction mechanism, and worktable, forms a continuous material flow. After the workpiece is conveyed to the fixed feeding point, the suction mechanism immediately intervenes, eliminating the need for manual transfer and reducing waiting time between processes. By transporting the workpiece to the target point on the worktable surface in a preset posture, it ensures that the position and angle of each feeding are highly consistent, laying a solid foundation for the accuracy of subsequent laser cutting and eliminating processing errors caused by manual placement deviations. In addition, the introduction of the rotary drive unit allows the second drive assembly and all subsequent components to rotate as a whole relative to the first drive assembly.

Combining linear movement and rotational motion, the effective working range of the suction mechanism forms a more complex and flexibly covered area, enabling material to be picked up and placed from more diverse directions.

[0032] Please see Figures 1 to 2This utility model discloses a laser cutting machine loading mechanism 1, which includes a worktable 10, a conveying mechanism 20, and a suction mechanism 30. The worktable 10 serves as the material support structure of the laser cutting machine for holding the plate-shaped workpiece to be cut. Accordingly, the conveying mechanism 20 is located on the adjacent side of the worktable 10, and the suction mechanism 30 is located between the worktable 10 and the conveying mechanism 20. Thus, when the workpiece is conveyed to the loading point by the conveying mechanism 20, the suction mechanism 30 picks up the workpiece at the loading point of the conveying mechanism 20 and then transports the workpiece to the target point on the surface of the worktable 10 in a preset posture, thereby completing the loading process. Specifically, the material suction mechanism 30 includes a first drive assembly 31, a second drive assembly 32, a third drive assembly 33, a fourth drive assembly 34, and a material suction assembly 36; the first drive assembly 31 is slidably mounted on the side edge of the worktable 10; the second drive assembly 32 is movably mounted on the output end of the first drive assembly 31; the third drive assembly 33 is movably mounted on the output end of the second drive assembly 32; the fourth drive assembly 34 is movably mounted on the output end of the third drive assembly 33; and the material suction assembly 36 is mounted on the output end of the fourth drive assembly 34, thereby realizing multi-axis drive of the material suction assembly 36. More specifically, the material suction mechanism 30 also includes a rotary drive unit 35, which is disposed between the first drive assembly 31 and the second drive assembly 32. That is, the rotary drive unit 35 is installed at the output end of the first drive assembly 31, and the second drive assembly 32 is movably installed at the output end of the rotary drive unit 35. Thus, the second drive assembly 32 can move along a preset direction under the drive of the first drive assembly 31, and can also rotate relative to the first drive assembly 31 under the drive of the rotary drive unit 35. This greatly enhances the flexibility of the material suction assembly 36 relative to the worktable 10 and the conveying mechanism 20, and strengthens its applicability to various material feeding conditions.Based on the above configuration, the laser cutting loading mechanism of this solution is spatially closely connected through the conveying mechanism 20, the suction mechanism 30, and the worktable 10, forming a continuous material flow. After the workpiece is conveyed to the fixed loading point, the suction mechanism 30 immediately intervenes, eliminating the need for manual transfer and reducing waiting time between processes. By transporting the workpiece to the target position on the surface of the worktable 10 in a preset posture, the position and angle of each loading are highly consistent, laying a solid foundation for the accuracy of subsequent laser cutting and eliminating processing errors caused by manual placement deviations. In addition, the introduction of the rotary drive unit 35 allows the second drive assembly 32 and all subsequent components to rotate as a whole relative to the first drive assembly 31. The suction assembly 36 can approach or leave the workpiece and the worktable 10 from an inclined angle, effectively avoiding mechanical obstacles in the path. It can rotate the workpiece in the plane during transportation or before placement, making it more compatible with the target posture on the worktable 10. Combining linear movement and rotational motion, the effective working range of the suction mechanism 30 forms a more complex and flexibly covered area, enabling material to be picked up and placed from more diverse directions.
[0033] Specifically, in one embodiment, the first drive component 31 extends along the length of the worktable 10 and is installed on the side surface of the worktable 10 facing the conveying mechanism 20, so that the output end of the first drive component 31 can drive the load to reciprocate along the length of the worktable 10; in another embodiment, the first drive component 31 adopts a ball screw module and a servo motor to form a linear slide module to meet the long stroke positioning requirements.
[0034] Specifically, in one embodiment, the rotary drive unit 35 adopts a hollow rotary platform in conjunction with a servo motor to form a rotary drive mechanism, thereby ensuring high rigidity and high rotational accuracy; in another embodiment, the bottom surface of the rotary drive unit 35 is connected to the top surface of the output end of the first drive component 31, and the output end of the rotary drive unit 35 is set facing the top side so that the second drive component 32 can be mounted on the top side of the worktable 10, thereby facilitating workpiece handling.
[0035] Specifically, in one embodiment, the second drive assembly 32 is disposed parallel to the top side surface of the worktable 10 at the output end of the rotary drive unit 35, enabling the second drive assembly 32 to drive its load to reciprocate in a direction parallel to the worktable 10; in another embodiment, the second drive assembly 32 adopts a lightweight aluminum alloy ball screw module in conjunction with a servo motor to form a linear slide module, so as to reduce the weight of the moving parts and improve the response speed and overall stability.
[0036] Specifically, in one embodiment, the top surface of the third drive component 33 is disposed on the output end of the second drive component 32, enabling the third drive component 33 to drive the load to reciprocate up and down in a direction perpendicular to the worktable 10; in another embodiment, the third drive component 33 adopts a servo electric cylinder with brake to achieve precise control of lifting and lowering, stable placement of the plate, and the braking function can ensure the safety of loading.
[0037] Specifically, in one embodiment, the fourth drive component 34 is disposed parallel to the top side surface of the worktable 10 at the output end of the third drive component 33, enabling the fourth drive component 34 to drive the suction component 36 to perform horizontal fine-tuning; in another embodiment, the fourth drive component 34 adopts a compact single-axis electric slide module to ensure the reliability of the fourth drive component 34.
[0038] Furthermore, the output end of the third drive assembly 33 is provided with a sliding plate 331 for mounting the fourth drive assembly 34. Specifically, the third drive assembly 33 is also provided with an edge finder 332 for precise positioning of the feeding plate.
[0039] Furthermore, the suction assembly 36 includes a plurality of suction cups 361, which are connected to the output end of the fourth drive assembly 34 via a mounting bracket 362, thereby forming an array of suction cups 361 to stably pick up plate-shaped workpieces.
[0040] Specifically, in one embodiment, the conveying mechanism 20 adopts a conveyor belt and is disposed on the bottom side of one end of the second drive component 32, so that the moving range of the suction component 36 can cover the conveying mechanism 20, and the plate-shaped workpiece can be conveyed to the loading point by the conveyor belt so that a plurality of suction cups 361 can pick up the plate-shaped workpiece.
[0041] Furthermore, a mounting base 11 is provided on the bottom side of the workbench 10. The mounting base 11 is located adjacent to the conveying mechanism 20 and provides stable support for the workbench 10.
[0042] Furthermore, guide mechanisms 12 are respectively provided at both ends of the worktable 10 for conveying and guiding the plate-shaped workpieces at both ends of the worktable 10.
[0043] In summary, the laser cutting machine feeding mechanism disclosed in this utility model forms a continuous material flow through the close spatial connection of the conveying mechanism, the suction mechanism, and the worktable. After the workpiece is conveyed to the fixed feeding point, the suction mechanism immediately intervenes, eliminating the need for manual transfer and reducing waiting time between processes. By transporting the workpiece to the target point on the worktable surface in a preset posture, the position and angle of each feeding are highly consistent, laying a solid foundation for the accuracy of subsequent laser cutting and eliminating processing errors caused by manual placement deviations. In addition, the introduction of the rotary drive unit allows the second drive assembly and all subsequent components to rotate as a whole relative to the first drive assembly. The suction assembly can approach or leave the workpiece and worktable from an inclined angle, effectively avoiding mechanical obstacles in the path. It can rotate the workpiece in the plane during transportation or before placement, making its matching degree with the target posture on the worktable higher. Combining linear movement and rotational motion, the effective working range of the suction mechanism forms a more complex and flexibly covered area, enabling material to be picked up and placed from more diverse directions.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
