[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figures 1-6As shown, the metal 3D printed product quality monitoring device includes a housing 1, a guide rail 2 fixedly installed inside the housing 1, a movable plate 3 slidably installed on the guide rail 2, a placement seat 4 fixedly connected to the movable plate 3, a servo motor 5 inside the placement seat 4, a drive gear 6 rotatably connected to the placement seat 4 on the lower side of the servo motor 5, the output shaft of the servo motor 5 fixedly connected to the drive gear 6, four sets of transmission gears 7 meshing on the drive gear 6, the transmission gears 7 rotatably mounted in the placement seat 4 via a rotating shaft 9, a sprocket 8 fixedly connected to the rotating shaft 9 on the upper side of the transmission gears 7, and a transmission chain 10 meshing on the sprocket 8. One end of the transmission chain 10 is engaged with a sprocket 11. A lifting assembly 12 is connected to the sprocket 11. The lifting assembly 12 includes a threaded rod 1203 fixedly connected to the sprocket 11. A lifting frame 1201 fixedly connected to the placement seat 4 is provided on the outside of the threaded rod 1203. The threaded rod 1203 is rotatably installed in the lifting frame 1201. A moving block 1205 is threadedly connected to the threaded rod 1203. A slide rod 1204 slidably connected to the moving block 1205 is provided on one side of the threaded rod 1203. An angle adjustment mechanism 13 is fixedly installed on the moving block 1205. A monitoring camera 14 is provided on the angle adjustment mechanism 13. When printing, the servo motor 5 starts, driving the drive gear 6 to rotate. The drive gear 6 then drives the four sets of transmission gears 7 meshing on the outside to rotate synchronously. The transmission gears 7 then drive the upper sprocket 8 to rotate via the rotating shaft 9. The sprocket 8 then drives the transmission chain 10 to rotate the sprocket 11, causing the sprocket 11 to rotate. This causes the threaded rod 1203 in the lifting mechanism 12 to rotate. When the threaded rod 1203 rotates, it engages with the slide rod 1204, driving the moving block 1205 on its surface to move up and down, thereby enabling the four sets of lifting components 12 to move. Synchronous lifting and lowering allows the monitoring camera 14 to move upwards layer by layer as the printing height increases, tracking the printing status of each layer in real time. This avoids blind spots caused by height changes and eliminates the risk of missed detection that is common with traditional fixed-height monitoring cameras 14. During the lifting and lowering process, the angle adjustment mechanism 13 can adjust the elevation and depression angles of the monitoring camera 14, allowing it to tilt and observe suspended structures, inclined surface structures, or complex support areas. By taking pictures of the product from different angles, errors in the accuracy of the printed product are avoided due to the shooting angle.

[0024] Specifically, in this embodiment, a mounting bracket 501 is fixedly connected to the outer side of the servo motor 5, and the upper end of the mounting bracket 501 is fixedly connected to the inner wall of the placement base 4. The mounting bracket 501 allows the servo motor 5 to be stably installed inside the placement base 4.

[0025] Specifically, in this embodiment, the placement seat 4 is provided with four sets of fixing slots 401 for cooperating with the transmission chain 10, and the four sets of fixing slots 401 correspond to the four sets of transmission chains 10.

[0026] Specifically, in this embodiment, a partition 1202 is fixedly connected to the inner wall of the lifting frame 1201. The partition 1202 is rotatably connected to the threaded rod 1203. A sprocket 11 is disposed on the lower side of the partition 1202, and a slide rod 1204 is disposed on the upper side of the partition 1202. Both ends of the slide rod 1204 are fixedly connected to the inner wall of the lifting frame 1201 and the upper end of the partition 1202, respectively. The slide rod 1204 can limit the movement of the moving block 1205, allowing it to move up and down along the surface of the threaded rod 1203.

[0027] Specifically, in this embodiment, the angle adjustment mechanism 13 includes an adjustment box 1301 fixedly connected to the moving block 1205. A cylinder 1302 is fixedly installed inside the adjustment box 1301. An adjustment block 1303 is fixedly connected to the output shaft of the cylinder 1302. A connecting rod 1304 is fixedly connected to both ends of the adjustment block 1303. An adjustment rod 1305 is rotatably installed on the connecting rod 1304. A crank rod 1306 is rotatably installed on the upper side of the adjustment rod 1305 and mounted on the adjustment box 1301. The upper end of the adjustment rod 1305 is rotatably connected to the lower end of the crank rod 1306. A mounting plate 1307 is fixedly connected to the upper ends of both crank rods 1306. A monitoring camera 14 is fixedly installed on the mounting plate 1307. The angle adjustment mechanism 13 is driven by the cylinder 1301, which causes the cylinder 1301 to move the adjusting block 1302 up and down. When the adjusting block 1302 moves upward, it causes the connecting rod 1304 to move upward. During the upward movement of the connecting rod 1304, the adjusting rod 1305 drives the crank rod 1306 connected to it to rotate, causing the other end of the crank rod 1306 to drive the mounting plate 1307 to rotate downward, thus driving the monitoring camera 14 to rotate downward. Conversely, it drives the monitoring camera 14 to rotate upward, thereby adjusting the angle of the monitoring camera 14.

[0028] Specifically, in this embodiment, guide grooves 1308 are provided on both sides of the upper end of the adjustment box 1301. The guide grooves 1308 are generally arranged in the shape of a quarter circle. Guide rods that are adapted to the guide grooves 1308 are fixedly connected to the two crank rods 1306. Through grooves 1309 for sliding of the connecting rod 1304 are provided on both sides of the lower end of the adjustment box 1301. Through the cooperation of the guide grooves 1308 and the guide rods, the rotation range of the crank rods 1306 can be limited, thereby limiting the maximum adjustment angle of the monitoring camera 14.

[0029] The working principle of this utility model is as follows: When printing, the servo motor 5 starts, and the servo motor 5 drives the active gear 6 to rotate. The rotation of the active gear 6 drives the four sets of transmission gears 7 meshing on the outside to rotate synchronously. The transmission gears 7 then drive the upper sprocket 8 to rotate through the rotating shaft 9. The sprocket 8 then drives the transmission chain 10 to drive the sprocket 11 to rotate, so that the sprocket 11 drives the threaded rod 1203 in the lifting mechanism 12 to rotate. When the threaded rod 1203 rotates, it cooperates with the slide rod 1204, which can drive the moving block 1205 on its surface to move up and down. This enables the four sets of lifting components 12 to move up and down synchronously, so that the monitoring camera 14 can move up layer by layer as the printing layer height increases, and track the printing status of each layer in real time. This avoids blind spots caused by height changes and avoids the risk of missed detection that is common in traditional fixed-height monitoring cameras 14.

[0030] Meanwhile, during the lifting and lowering process, the angle adjustment mechanism 13 is driven by the cylinder 1301, which causes the cylinder 1301 to move the adjusting block 1302 up and down. When the adjusting block 1302 moves upward, it in turn drives the connecting rod 1304 to move upward. During the upward movement of the connecting rod 1304, it drives the crank rod 1306 connected to it to rotate through the adjusting rod 1305. This causes the other end of the crank rod 1306 to drive the mounting plate 1307 to rotate downward, thus driving the monitoring camera 14 to rotate downward. Conversely, it drives the monitoring camera 14 to rotate upward, thereby adjusting the angle of the monitoring camera 14. The angle adjustment mechanism 13 can adjust the elevation and depression angles of the monitoring camera 14, allowing the monitoring camera 14 to tilt and observe the suspended structure, inclined surface structure, or complex support area. By shooting the product from different angles, errors in the accuracy of the printed product due to the shooting angle can be avoided.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
