Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a plate flipping device for laser cutting machines. Background Technology

[0002] Laser cutting technology, as a high-precision and high-efficiency material processing method, has been widely used in the cutting and engraving of various materials, including metals and non-metals. Its core principle lies in focusing a high-energy laser beam generated by a laser into a spot with extremely high power density through a precise optical path system, which then acts on the surface of the workpiece. When the laser energy absorbed in a localized area rapidly exceeds the melting or boiling point of the material, the material is melted, vaporized, or ablated, thereby achieving material separation or etching to form the desired cut or pattern.

[0003] Currently, mainstream industrial laser cutting equipment generally adopts a single-sided cutting mode. This mode is highly effective for processing single-layer homogeneous sheets (such as steel plates, acrylic sheets, etc.). However, when dealing with workpieces with complex internal structures, such as plates containing hollow cavities, or composite sheets composed of multiple layers of heterogeneous materials, the limitations of existing technology become apparent. Single-sided cutting can only operate on one surface of the sheet material: this means that:

[0004] 1. Unable to penetrate internal structures or layers: After cutting the surface, the laser beam cannot effectively process the internal structures (such as inner circuits, hollow cavity walls, bottom materials, etc.) that are blocked by the surface.

[0005] 2. Flipping operation required: In order to complete the cutting of the other side or internal structure, the workpiece must be removed from the worktable, flipped manually or with the help of a complex mechanism, and then repositioned for a second cutting.

[0006] 3. Increased Operational Complexity: The added flipping step significantly reduces processing efficiency and increases operational difficulty. Alignment and Calibration are Difficult: After flipping, accurately positioning the workpiece and ensuring precise alignment and centering of the second cutting path with the first cutting path in three-dimensional space (especially in the thickness direction and planar position) is extremely challenging. Even minor positioning errors can lead to misalignment of the cuts on both sides and inaccurate cutting of the internal structure, severely impacting product precision and quality.

[0007] Therefore, there is a need to design a device that facilitates the flipping of laser-cut sheet metal. Utility Model Content

[0008] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sheet metal flipping device for a laser cutting machine.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a plate flipping device for a laser cutting machine, comprising: a flipping base, a flipping worktable, a flipping drive assembly, and a clamping assembly;

[0010] The flipping worktable is equipped with a circular rolling frame, which is rotatably mounted on the flipping base; the flipping drive assembly is used to drive the circular rolling frame to rotate and to make the flipping worktable flip and move; the clamping assembly is provided on the flipping worktable and is used to clamp the plate of the flipping worktable.

[0011] Preferably, at least two circular tumbling frames are spaced apart.

[0012] Preferably, the flipping base is provided with a support platform; the support platform is provided with a tumbling support roller; and the circular tumbling frame is mounted above the tumbling support roller.

[0013] Preferably, the flipping worktable is provided with a plurality of rolling rollers, which are arranged in two layers, one above the other; a material conveying space is formed between the two layers of rolling rollers.

[0014] Preferably, the circular rolling frame has a material clearance groove; side support plates are provided on both sides of the material clearance groove; and the two ends of the rolling roller are rotatably mounted on the side support plates.

[0015] Preferably, the clamping assembly includes two clamping plates and a clamping drive; the two clamping plates are spaced apart on both sides of the plate conveying space; the clamping drive is used to move the two clamping plates toward each other and clamp the plate.

[0016] Preferably, the clamping components are provided in at least two sets at intervals.

[0017] Preferably, the circular tumbling frame is provided with an annular transmission groove; the tumbling drive assembly includes a tumbling drive motor, a first rotary transmission component, and a second rotary transmission component; the first rotary transmission component is installed at the output end of the tumbling drive motor, and the second rotary transmission component is embedded in the transmission groove and is not exposed outside the transmission groove; the tumbling drive motor is disposed on the tumbling base, and can drive the circular tumbling frame to rotate through the first and second rotary transmission components.

[0018] Preferably, the first rotary transmission component is a drive gear, and the second rotary transmission component is a gear ring, with the drive gear meshing with the gear ring for transmission.

[0019] Preferably, the first and second rotary transmission components are synchronous pulleys and rotate synchronously via a synchronous belt;

[0020] Alternatively, the first and second rotary transmission components are chain wheels, which rotate synchronously via a synchronous chain.

[0021] The beneficial effects of this invention are as follows: By driving a rotating worktable with a circular tumbling frame through a rotating drive assembly, the device can automatically complete a 180° rotation of the sheet material. This completely eliminates the traditional manual handling and rotation processes that require manual intervention or complex external mechanisms, significantly improving rotation efficiency and shortening the overall processing cycle for double-sided cutting of composite sheets.

[0032] Example

[0033] Reference Figure 1 and Figure 2 The present invention proposes a sheet metal flipping device for a laser cutting machine, comprising: a flipping base 10, a flipping worktable 20, a flipping drive assembly 30, and a clamping assembly 40;

[0034] The flipping worktable 20 is provided with a circular rolling frame 21, which is rotatably mounted on the flipping base 10; the flipping drive assembly 30 is used to drive the circular rolling frame 21 to rotate and make the flipping worktable 20 flip and move; the clamping assembly 40 is provided on the flipping worktable 20 and is used to clamp the plate of the flipping worktable 20.

[0035] In this invention, the flipping drive assembly 30 drives the flipping worktable 20 with a circular flipping frame 21 to perform precise rotational motion, which can automatically complete the 180° flipping of the board. This completely eliminates the traditional operation process that requires manual intervention or complex external mechanisms for manual loading, unloading, and flipping, greatly improving flipping efficiency and shortening the overall processing cycle of double-sided cutting of composite boards. This equipment is integrated into the laser cutting machine (or as a functional module), has a compact structure, and is easy to operate. Automated flipping reduces reliance on skilled operators and lowers the risk of human error. At the same time, it avoids the need for a large and complex independent flipping mechanism, reducing the overall complexity and manufacturing cost of the equipment.

[0036] In this embodiment, at least two circular tumbling frames 21 are spaced apart. Multiple support points distribute the load, preventing deformation or shaking when large-sized plates are flipped, thus enhancing stability.

[0037] In this embodiment, the flipping base 10 is provided with a support platform 11; the support platform 11 is provided with a tumbling support roller 12; and a circular tumbling frame 21 is mounted above the tumbling support roller 12. The support roller achieves rolling friction, reduces frictional resistance, reduces drive energy consumption, and extends equipment life. The support platform 11 provides rigid support to ensure a smooth flipping process for heavy plates.

[0038] In this embodiment, the tilting worktable 20 is equipped with a plurality of rolling rollers 22, which are arranged in two layers, forming a sheet material conveying space 50 between the two layers of rolling rollers 22. The double-layered rolling rollers 22 forming the sheet material conveying space 50 can directly connect to the conveying system of the laser cutting machine, realizing automatic sheet material loading / unloading and reducing manual intervention. This protects the sheet material surface, and the rolling conveying avoids scratching precision workpieces.

[0039] In this embodiment, the circular tumbling frame 21 has a material clearance groove 211; side support plates 23 are provided on both sides of the material clearance groove 211; the two ends of the rolling roller 22 are rotatably mounted on the side support plates 23. The material clearance groove provides movement space for the laser cutting head, supports direct cutting after flipping, and avoids structural interference. The side support plates 23 enhance the installation stability of the rolling roller 22, prevent the roller shaft from shifting during flipping, and optimize the rigid structure.

[0040] In this embodiment, the flipping worktable 20 is equipped with an active drive roller, which enables the sheet material to move forward independently on the flipping worktable 20.

[0041] In this embodiment, the clamping assembly 40 includes two clamping plates 41 and a clamping drive 42; the two clamping plates 41 are spaced apart on both sides of the plate conveying space 50; the clamping drive 42 is used to move the two clamping plates 41 toward each other and clamp the plate. Adaptive clamping force: The drive controls the clamping plates 41 to move toward each other, which can adapt to plates of different thicknesses. Anti-offset design: Vertical clamping prevents the plate from slipping during flipping, ensuring accurate internal structural cutting positions.

[0042] In this embodiment, at least two sets of clamping assemblies 40 are spaced apart. Multi-point clamping counteracts the torque during plate rotation, preventing deformation of thin plates. Even pressure distribution avoids localized stress concentration that could damage the workpiece.

[0043] In this embodiment, the circular tumbling frame 21 is provided with an annular transmission groove 212; the tumbling drive assembly 30 includes a tumbling drive motor, a first rotary transmission component (not shown in the figure), and a second rotary transmission component (not shown in the figure); the first rotary transmission component is installed at the output end of the tumbling drive motor, and the second rotary transmission component is embedded in the transmission groove 212 and is not exposed outside the transmission groove 212; the tumbling drive motor is disposed on the tumbling base 10, and can drive the circular tumbling frame 21 to rotate through the first and second rotary transmission components. To avoid safety risks, the second rotary transmission component is embedded in the tumbling frame, avoiding mechanical damage caused by exposure. To improve transmission accuracy, the closed groove structure reduces dust contamination, ensures gear meshing stability, and does not interfere with or damage the tumbling support roller 12 of the support platform 11.

[0044] In this embodiment, the flipping worktable 20 is equipped with an active drive roller, which enables the sheet material to move forward independently on the flipping worktable 20.

[0045] In some embodiments, the first rotary transmission component is a drive gear, and the second rotary transmission component is a gear ring, with the drive gear meshing with the gear ring for transmission. It features high torque transmission, is suitable for heavy-duty sheet metal flipping, and has strong instantaneous load capacity. It offers precise angle control and high gear indexing accuracy.

[0046] In some embodiments, the first and second rotary transmission components are synchronous pulleys that rotate synchronously via a synchronous belt; or, the first and second rotary transmission components are chain pulleys that rotate synchronously via a synchronous chain. Compared to gear transmission, this reduces noise, and the flexible transmission reduces mechanical impact, protecting precision workpieces.

[0047] The board flipping device is also equipped with sensors to detect the flipping angle or the position of the board.

[0048] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
