Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A real-time monitoring device suitable for powder-feed laser additive manufacturing, such as... Figures 1-7As shown, the device includes a cabinet 1, a connecting plate 101, a side plate 2, an electric slide rail 1 3, a mounting plate 4, a flexible robotic arm 5, a laser head assembly 6, a motor 7, a placement plate 8, a monitoring camera 9, an electric slide rail 2 901, a wiping cylinder 902, a supplementary light 10, a vacuum cleaner head 11, a guide rail 12, a cleaning rod 13, a guide rod 14, and a closed door 15. The cabinet 1 provides support and storage space for the entire device. The upper front of the cabinet 1 is connected to the side plate 2. The rear side of the cabinet 1 is symmetrically and vertically mounted with electric slide rail 1 3. Electric sliders are slidably mounted on each of the electric slide rail 1 3. A mounting plate 4 connects the two electric sliders. A flexible robotic arm 5 is mounted on the front of the mounting plate 4. The lower end of the flexible robotic arm 5 is mounted with... The system includes a laser head assembly 6 and an electric slide rail 3 that provides a vertical sliding track for the mounting plate 4, enabling vertical movement of the laser head assembly 6. A flexible robotic arm 5 allows for flexible posture adjustment, allowing the laser head assembly 6 to reach the appropriate position for processing. The laser head assembly 6 emits laser light, enabling powder-feeding laser additive manufacturing. A connecting plate 101 is horizontally connected to the bottom of the cabinet 1. A motor 7 is installed at the center of the bottom of the cabinet 1, and the output shaft of the motor 7 is connected to a placement plate 8. The placement plate 8 is used to place the workpiece to be processed and rotates with the drive of the motor 7. The placement plate 8 is located on top of the connecting plate 101. A monitoring camera 9 is rotatably mounted on the front top of the cabinet 1 via a connecting plate. The monitoring camera 9 is used for... To monitor the workpiece status and processing conditions in real time during laser additive manufacturing, electric slide rails 901 are horizontally mounted on both the front and rear sides of the monitoring camera 9. A wiping cylinder 902 is slidably connected between the electric slide rails 901 via an electric slider. Sliding the wiping cylinder 902 to the left wipes the surface of the monitoring camera 9, keeping it clean and ensuring monitoring effectiveness. A supplementary light 10 is installed at the top front of the cabinet 1, providing sufficient illumination for the monitoring camera 9 and improving the clarity of the monitoring image. A vacuum cleaner head 11 is embedded on both the lower left and right sides of the cabinet 1, with the suction port of the vacuum cleaner head 11 facing the top of the placement plate 8. The vacuum head 11 is used to absorb dust and waste generated during processing, keeping the inside of the cabinet 1 clean. Guide rails 12 are connected to the top left and right sides of the connecting plate 101. A cleaning rod 13 is slidably connected between the two guide rails 12. The cleaning rod 13 is located above the placement plate 8. Sliding the cleaning rod 13 back and forth can clean the surface of the placement plate 8 and remove residual powder and impurities. Guide rods 14 are vertically connected to the left and right sides of the front of the cabinet 1. A closing door 15 is slidably connected between the two guide rods 14. The guide rods 14 provide sliding tracks for the closing door 15, enabling the closing door 15 to move up and down. This is used to close the front of the cabinet 1, preventing dust and waste from leaking out during processing, and also providing safety protection.

[0024] When using real-time monitoring equipment for powder-feed laser additive manufacturing, first place the workpiece to be processed stably on the placement plate 8, ensuring its accurate position and preventing it from shifting or falling during rotation. Connect the equipment power supply and turn on the equipment control switch to put the equipment into standby mode. Control the movement of the electric slider on the electric slide rail 3, which drives the mounting plate 4 to move vertically, thereby adjusting the height of the flexible robotic arm 5 and the laser head assembly 6 to reach the appropriate processing position. At the same time, through the flexible adjustment of the flexible robotic arm 5, the laser head assembly 6 can be precisely aligned with the processing area of ​​the workpiece.

[0025] The laser head assembly 6 is activated to emit a laser beam, and the powder feeding device is simultaneously turned on to begin powder-feed laser additive manufacturing. Motor 7 drives the placement plate 8 to rotate, ensuring uniform heating and additive processing of the workpiece. During processing, monitoring camera 9 monitors the workpiece status and processing conditions in real time, transmitting the monitoring images to the equipment control panel or connected computer software for display. Operators can observe the monitoring images to understand the processing progress and quality. Supplemental lighting 10 provides sufficient illumination for monitoring camera 9, ensuring the clarity of the monitoring images. When dust or stains on the surface of monitoring camera 9 affect the monitoring effect, the electric slider on electric slide rail 901 is moved, causing the wiping cylinder 902 to slide and wipe the surface of monitoring camera 9, keeping it clean.

[0026] After processing is complete, sequentially shut down the powder feeding device, laser head assembly 6, and motor 7 to stop the processing. After the placement plate 8 stops rotating, turn on the vacuum head 11 to remove any remaining powder and impurities from the placement plate 8. After vacuuming, manually slide the cleaning rod 13 back and forth to move it on the guide rail 12 to clean the surface of the placement plate 8, removing any fine powder and impurities. After cleaning is complete, turn off the equipment control switch and disconnect the power supply to shut down the equipment.
