[0052] This laser cutting machine has a structure that enables automatic picking and palletizing of sheet metal products, while simultaneously removing waste material from the parts, thus achieving automatic intelligent palletizing and sorting of parts.

[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0054] Embodiment 1 of the laser cutting machine of this application

[0055] Reference Figures 1-17 The laser cutting machine of this application includes a laser cutting component and a sorting component;

[0056] like Figure 3 As shown, the laser cutting assembly includes a bed 8, an outer cover 6 on the outside of the bed 8, Z-axis 7 symmetrically arranged on both sides of the bed 8, a crossbeam 9 slidably arranged between the two Z-axis 7, and the crossbeam 9 can move along the Z-axis 7; a laser cutter 10 is arranged on the crossbeam 9, and the laser cutter 10 can move along the direction of the crossbeam 9.

[0057] like Figure 4 As shown, the sorting assembly includes a robot track 1, a robot 2, a pickup 3, and a cutting platform 4. The robot track 1 and the cutting platform 4 are arranged in parallel, and the robot 2 can be moved and positioned on the robot track 1. The pickup 3 is located at the end of the robot 2 and is used to pick up the cut products. One end of the cutting platform 4 is opposite to one end of the bed 8, and the bed 8 is equipped with drive motors 5 on both sides of the end of the bed 8 closest to the cutting platform 4. The drive motors 5 drive the exchange platform 402 on the cutting platform 4 to enter the bed 8 for material exchange and feeding via a chain.

[0058] like Figures 10-13 As shown, the cutting work platform 4 includes a fixed worktable 401, with an exchange platform 402 at the upper end of the fixed worktable 401. The bottom of the exchange platform 402 can move between the fixed worktable 401 and the bed 8 via rollers. The exchange platform 402 is provided with a clamping member 403 and a clamping plate assembly 404. The clamping member 403 is located on one side edge of the exchange platform 402, and the clamping plate assembly 404 is located at the upper end of the exchange platform 402. The clamping plate assembly 404 includes multiple horizontally arranged clamping plates 40 41 and multiple longitudinally arranged support bars 4042, the two ends of the card plate 4041 are installed at both ends of the exchange platform 402 by card plate fixing parts 4043, the support bars 4042 are located above the card plate 4041, the front and rear sides of the exchange platform 402 are provided with support bar pads 4044, the upper end of the support bar pads 4044 is provided with support bar pressure plates 4045, the two ends of the support bars 4042 are respectively located on the support bar pads 4044 on both sides, and are pressed and fixed by the support bar pressure plates 4045.

[0059] During material loading, the sheet metal is placed against the clamping member 403, and the position of the support bar 4042 is adjusted so that a hollow clearance hole is formed between adjacent support bars 4042. This ensures that the waste material on the part to be cut by the customer is hollowed out and has no support bar installed. Then the waste material falls through the hollow clearance hole, and some of the waste material has already fallen through this clearance hole during the cutting process.

[0060] like Figures 5-8 As shown, the robot track 1 includes a frame 101, a slide plate 102 is slidably mounted on the frame 101, a transmission system 104 is provided at the end of the frame 101, the transmission system 104 can drive the slide plate 102 to move along the direction of the frame 101, and a robot 2 is mounted on the upper surface of the slide plate 102.

[0061] The transmission system 104 includes an AC servo motor 1041 and a reducer 1042 mounted on the slide plate 102. The reducer 1042 is mounted on the output end of the AC servo motor 1041. The output end of the reducer 1042 is provided with a gear 1044, and the inner side of the frame 101 is provided with a rack 1043. The gear 1044 meshes with the rack 1043. When the AC servo motor 1041 works, it drives the gear 1044 to rotate, thereby driving the slide plate 102 and the robot 2 to move along the length direction of the frame 101; realizing robot movement, and the effective stroke meets the workpiece handling requirements.

[0062] The two ends of the frame 101 are also equipped with protective structures 103 to protect the robot track 1 from interference from external dust and iron filings and other foreign objects. The protective devices are stable, reliable and not easily damaged.

[0063] like Figures 14-16 As shown, the pickup 3 includes a fixed bracket 301. The upper end of the fixed bracket 301 is connected to the end of the robot 2 by bolts. Electro-permanent magnets 302 are connected to both sides of the lower end of the fixed bracket 301 by buffer mechanisms 303. The electro-permanent magnets 302 are used to adsorb sheet metal parts. Cylinders 305 are also symmetrically arranged on both sides of the fixed bracket 301. The movable end of the cylinder 305 is connected to a push rod mechanism 304 for removing waste materials adhering to the parts.

[0064] The pickup 3 uses an electro-permanent magnet 302 to attract parts. While picking up the parts, the waste pusher mechanism 304 uses a cylinder 305 with a pusher mechanism 304 to remove the waste. Since the workpiece cannot be kept parallel to the ground throughout the process of grabbing the workpiece, considering the problems of prying and tipping of the parts, a guide and spring buffer structure is added. The whole is connected by a fixed bracket 301 to form a complete pickup structure. An external protective cover 306 is added for protection, and finally it is connected to the robot.

[0065] The buffer mechanism 303 consists of a guide rod and a spring, with the spring sleeved on the outside of the guide rod.

[0066] The outer side of the fixed bracket 301 is provided with a protective cover 306, which serves a protective function.

[0067] Pickup 3 has a power failure protection function. When there is an abnormal power failure, the workpiece will be firmly attached to pickup 3 and will not fall off.

[0068] Embodiment 2 of the laser cutting machine of this application

[0069] The laser cutting machine of this application further includes a controller, which is connected to the robot 2, the laser cutter 10, and the drive motor 5, and is used to control their operation. Specifically, the controller controls the actions to guide and control the robot, drive components, and cutter, and completes the tasks of cutting, picking up, and placing parts.

[0070] This laser cutting machine improves production efficiency, reduces labor burden, and lowers production costs through automated control. It features high efficiency, low cost, and easy operation, and can enhance the construction of intelligent factories.

[0071] The working process of this utility model:

[0072] During loading, the product 11 (metal sheet) is placed against the clamping part 403 on the exchange platform 402 for initial positioning, and the clamping plate assembly 404 is adjusted so that the sheet can avoid the waste block.

[0073] Then, the exchange platform 402 is transported to the cutting area by the drive motor 5. The cutting machine is positioned by edge finding and the system nesting diagram is used. The laser cutter 10 is moved and cut by the controller.

[0074] After cutting, the parts are transported to the sorting station via the exchange platform 402. Robot 2 then automatically grabs and stacks the parts on the steel plate according to the cutting positioning and nesting diagram provided by the cutting machine. At the same time, the push rod mechanism 304 in the picker 3 pushes off the scrap blocks that have not fallen off in the product 11 in the clearance position to ensure the integrity of the product 11, thereby realizing automatic intelligent palletizing and sorting of parts.

[0075] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
