[0002] Laser cutting is an advanced manufacturing technology that uses a high-energy-density laser beam to cut materials. It is widely used in many industries such as metal processing, automobile manufacturing, aerospace, electronics, advertising, and handicraft production, and can handle the cutting needs of various metal and non-metal materials.

[0003] Existing laser cutting equipment usually uses robot cutting, and the workpiece is fixed on the workbench for cutting.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The present application discloses a multi-station robot 1 cutting device.

[0033] Reference Figure 1 A multi-station robot 1 cutting device comprises a robot 1, and a cutting device 11 is provided at the end of the robot 1. Several stations are arranged around the robot 1, and each station comprises a workbench 2. Such a design enables the device to cut multiple workpieces at the same time, thereby significantly improving production efficiency.

[0034] These several workstations can be workstations for processing workpieces of the same shape, workstations for processing workpieces of different shapes, or both. However, as many workstations as possible can be set around the robot 1 without affecting normal operation to further improve production efficiency. The drawings of this application only show three workstations for processing workpieces of different shapes. The other workstations refer to the technical solution of this application and are not shown in the drawings.

[0035] Example 1 This embodiment describes in detail the specific structure of the first workstation.

[0036] Reference Figure 2 and Figure 3 , each workbench 2 is equipped with a mold base 3 and a pressing device 4. The mold base 3 is composed of a bracket 31, a holder 32 and a base 33, and has a stable structure and is easy to adjust. The upper end of the bracket 31 is detachably connected to the holder 32 by bolts, and the base 33 is located below the bracket 31. This connection method not only ensures the stability of the structure, but also facilitates the replacement of the mold, thereby adapting to workpieces of different shapes and sizes. The shape of the holder 32 matches the shape of the workpiece to be cut, ensuring that the workpiece can be stably placed on the holder 32, reducing errors in the cutting process. The pressing device 4 is used to press the workpiece to be processed tightly on the mold base 3 to prevent the workpiece to be processed from moving during the cutting process, thereby improving the cutting accuracy.

[0037] Reference Figure 2 and Figure 4 The pressing device 4 specifically includes a pressing cylinder 41, a pressing plate 42 and a fixing plate 43 for connecting the pressing cylinder 41. When the pressing cylinder 41 works, it drives the pressing plate 42 to press down, thereby firmly pressing the workpiece to be processed on the die seat 3, ensuring the stability of cutting.

[0038] Reference Figure 2 and Figure 3In order to facilitate the robot 1 to perform all-round cutting of the irregular tubular workpiece to be processed, a clamping device 21 is provided on the workbench 2, and the clamping device includes a three-jaw chuck 211, a driving device and a chassis 212. The three-jaw chuck 211 is used to clamp the irregular tubular workpiece to be processed, and the driving device is installed in the chassis 212. The driving device is used to drive the three-jaw chuck 211 to clamp and fix the irregular tubular workpiece to be processed and rotate it to meet the all-round cutting requirements.

[0039] Reference Figure 2 and Figure 3 In order to facilitate the three-jaw chuck 211 to clamp the special-shaped tubular workpiece to be processed, a first sliding cylinder 22 is arranged on the workbench 2, and the output end of the first sliding cylinder 22 is fixedly connected to the chassis 212. The first sliding cylinder 22 pushes the clamping device 21 to move along the axis direction of the three-jaw chuck 211. Specifically, a slide rail extending along the axis direction of the three-jaw chuck 211 is arranged on the workbench 2, and a slider is arranged at the lower end of the chassis 212. The first sliding cylinder 22 pushes the chassis 212, and the slider slides on the slide rail, driving the three-jaw chuck 211 to move along the extension direction of the first sliding cylinder 22.

[0040] Reference Figure 2 Before the three-jaw chuck 211 clamps the special-shaped tubular workpiece to be processed, the clamping cylinder pushes the clamping plate to press the workpiece firmly on the clamping seat 32, thereby greatly reducing the possible movement of the workpiece to be processed during the clamping process and improving the clamping stability and cutting accuracy.

[0041] Reference Figure 4 The base 33 is fixedly connected with a lifting cylinder 311, and the output end of the lifting cylinder 311 is fixedly connected with the bracket 31. Through the operation of the lifting cylinder 311, the height of the irregular tubular workpiece to be processed can be adjusted so that the center of the irregular tubular workpiece to be processed corresponds to the axis of the three-jaw chuck 211. This not only facilitates the clamping of the workpiece by the three-jaw chuck 211, but also enables the equipment to adapt to the cutting requirements of different sizes, greatly enhancing the versatility of the equipment.

[0042] Reference Figure 3 and Figure 4 Two mold bases 3 are arranged around the three-jaw chuck 211. Both mold bases 3 move toward each other. The mold moves in the horizontal direction and is perpendicular to the axis direction of the three-jaw chuck 211. In order to drive the mold base 3 to move, a second sliding cylinder 23 is provided on the workbench 2, and the output end of the second sliding cylinder 23 is fixedly connected to the base 33. Specifically, a slide rail is provided on the workbench 2, and a slider is provided at the lower end of the base 33. The slider slides on the slide rail. The second cylinder pushes the base 33 to slide along the slide rail. The base 33 slides to drive the bracket 31 to move. The bracket 31 moves to drive the holder 32 to move. The holder 32 moves to transport the special-shaped tubular workpiece to be processed to the cutting position.

[0043] Reference Figure 3 and 4 The holders 32 on the two mold holders 3 correspond to the special-shaped tubular workpieces to be processed with different lengths and diameters. Two holders 32 are provided on the bracket 31 far away from the robot 1 for storing the slender special-shaped tubes 100 with smaller diameters and longer lengths; a holder 32 is provided on the bracket 31 close to the robot 1 for storing the thick and short special-shaped tubes 200 with larger diameters and shorter lengths.

[0044] Reference Figure 5 The lengths of the special-shaped tubular workpieces to be processed on the two mold seats 3 are different, resulting in different positions where the pressing cylinder 41 needs to be pressed. A third sliding cylinder 24 is arranged on the workbench 2, and the output end of the third sliding cylinder 24 is fixedly connected to the fixed plate 43. The third sliding cylinder 24 pushes the pressing cylinder 41 to move along the axis direction of the three-jaw chuck 211. Specifically, the fixed plate 43 is fixedly connected to the pressing cylinder 41, a slider is arranged at the lower end of the fixed plate 43, a column is arranged on the workbench 2, a slide rail is arranged on the column, the slide rail is located above the chuck 32, the slider slides on the slide rail, the third sliding cylinder 24 pushes the fixed plate 43 to slide along the slide rail, and the sliding of the fixed plate 43 drives the pressing cylinder 41 to move along the telescopic direction of the output end of the third sliding cylinder 24, thereby adjusting the position of the pressing device 4 to correspond to the position of the special-shaped tubular workpiece, thereby improving production efficiency.

[0045] Reference Figure 2 A material discharge port 25 is provided on the upper end surface of the workbench 2. A material discharge ramp 26 is provided at the material discharge port 25, and a material receiving box 27 is provided below the material discharge ramp 26. A handle 271 for taking the material receiving box 27 out of the workbench 2 is provided on the side of the material receiving box 27 away from the workbench 2. The waste materials and workpieces generated after cutting by the robot 1 fall onto the material discharge ramp 26, and fall into the material receiving box 27 along the material discharge ramp 26. When the material receiving box 27 is full or the materials of the workpieces to be processed are different, the operator pulls the handle 271 to pull the material receiving box 27 out of the workbench 2 and replace it with a new one. In order to save effort in pulling the material receiving box 27, moving wheels can be added below the material receiving box 27 or guide rails can be laid below.

[0046] Example 2 This embodiment is a specific structure of the second type of workstation.

[0047] The difference between this embodiment and the first embodiment is that the connection structure between the mold base 3 and the worktable 2 and the fixing and clamping method of the workpiece during cutting are different. The specific connection structure between the mold base 3 and the worktable 2 and the fixing and clamping method of the workpiece during cutting are shown below.

[0048] Reference Figure 6, a number of threaded holes are evenly arranged on the upper end surface of the workbench 2 along the direction of the workbench 2 toward the robot 1, and these threaded holes are symmetrically distributed on both sides of the workbench 2, and the lower end surface of the base 33 is abutted against the upper end of the workbench 2. The base 33 and the workbench 2 are detachably connected by bolts, and the threaded ends of the bolts pass through the base 33 and are inserted into the threaded holes. After the base 33 is moved to different positions on the workbench 2, the base 33 can be fixed to the workbench 2 with bolts, which realizes the flexible adjustment of the distance between the workpiece to be processed and the robot 1, and further improves the adaptability and flexibility of the equipment.

[0049] Reference Figure 7 and Figure 8 The design of the clamping seat 32 also fully considers the stability and cutting accuracy of the workpiece to be processed. The clamping seat 32 includes a stopper 321. When the pressing cylinder 41 pushes the pressing plate to press the workpiece to be processed, the stopper 321 is located on the side of the workpiece to be processed away from the pressing plate. The stopper 321 and the pressing plate clamp the workpiece to be processed together, ensuring the stability of the workpiece during the cutting process.

[0050] Reference Figure 7 The workpiece to be processed at the second station is a special-shaped part 300 with an opening at the bottom, and the holder 32 is a mold for the special-shaped part 300. The stopper 321 is located at the lower end surface of the holder 32. Two pressing devices 4 are provided on the base 33, and the workpiece to be processed is located between the two pressing devices 4. The fixed plate 43 is fixedly connected to the base 33, and the pressing cylinder 41 is fixedly connected to the fixed plate 43. The pressing cylinder 41 drives the pressing plate 42 to press on the workpiece to be processed, and presses the workpiece to be processed tightly.

[0051] Example 3 This embodiment is a specific structure of the third station. The difference between this embodiment and embodiment 2 is that the specific structures of the mold base 3 and the material pressing device 4 are different. The specific structures of the mold base 3 and the material pressing device 4 are shown below.

[0052] Reference Figure 8 , the workpiece to be processed in the third station is a square tube 400, and the holder 32 is a mold adapted to the square tube 400. The workpiece to be processed is placed on the upper end surface of the holder 32, and a limit plate 5 is set on the side of the bracket 31 away from the robot 1. The limit plate 5 is used to limit the maximum distance between the workpiece to be processed and the robot 1, which can assist in determining the cutting position and prevent the workpiece to be processed from moving during the cutting process. The end of the workpiece to be processed that abuts against the limit plate 5 can be an inclined surface, and a limit plate 5 is set to be rotatably connected to the bracket 31 to adapt to the inclined surface. The limit plate 5 also needs to be fixed while rotating. A limit cylinder 51 is set on the base 33, and the cylinder body of the limit cylinder 51 is rotatably connected to the base 33. The output end of the limit cylinder 51 is rotatably connected to the limit plate 5, and the rotation axis of the limit plate 5 is perpendicular to the rotation axis of the press plate 42. The output end of the limit cylinder 51 is telescopic to drive the limit plate 5 to rotate to abut the workpiece to be processed.

[0053] Reference Figure 8 The stopper 321 is located on the side of the upper end surface of the holder 32 close to the bolt. After the stopper plate 5 blocks one end of the workpiece to be processed, one side of the workpiece to be processed is abutted against the stopper 321, and the other side is pressed tightly using the press plate 42.

[0054] Reference Figure 8 The specific clamping method of the pressure plate 42 is as follows: the pressure plate 42 is rotatably connected to the bracket 31, the output end of the pressure cylinder 41 passes through the bracket 31 from under the clamping seat 32 and is rotatably connected to the pressure plate 42, the cylinder body of the pressure cylinder 41 is rotatably connected to the fixed plate 43, and the fixed plate 43 is fixedly connected to the base 33 on the side of the bracket 31 close to the stopper 321, and the output end of the pressure cylinder 41 is extended and retracted to drive the pressure plate 42 to rotate to clamp the workpiece to be processed.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
