[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1-4 , a 3D printing product appearance detection device, including a ring component 1 and a positioning component 2. A rotating mechanism with the function of rotating the gear 5 is arranged on the ring component 1. The rotating mechanism includes a motor 4 and a gear ring 101. The rotating end of the motor 4 is fixedly connected with a gear 5, and the gear 5 meshes with the gear ring 101. An inclined connecting rod 3 is fixedly connected to the positioning component 2, and the other end of the connecting rod 3 is fixedly connected to the top of the linear module 6. A linear module 6 is vertically installed on the positioning component 2;

[0020] It further includes a 3D scanner 9. A picking and placing mechanism with the function of installing and disassembling the mounting component 8 is arranged on the 3D scanner 9. The picking and placing mechanism includes a first shaping part 80 and a second shaping part 82. A slide block 81 is fixedly connected to the first shaping part 80. A chute 83 is opened in the second shaping part 82. The slide block 81 is slidably connected to the second shaping part 82. Ears 84 are fixedly connected to the tops of the first shaping part 80 and the second shaping part 82, and bolts 85 are threadedly connected to the ears 84.

[0021] In this embodiment, the ring component 1 is composed of a solid disk 100, a gear ring 101 and a ring 102. A to-be-detected part is placed at the center position of the solid disk 100. A gear ring 101 is fixedly connected to the top surface of the solid disk 100, and a ring 102 is fixedly connected to the top surface of the gear ring 101.

[0022] In this embodiment, the positioning component 2 includes a placing plate 20 and rollers 21. Rollers 21 are installed at the bottom of the placing plate 20. The positioning components 2 are installed in a circular array on the ring 102, and the rollers 21 are rollingly connected to the ring 102.

[0023] In this embodiment, a motor 4 is vertically installed on the positioning component 2 at the bottom of the linear module 6, and a positioning block 7 is fixedly connected to the sliding end of the linear module 6.

[0024] In this embodiment, the positioning block 7 is fixedly connected to the connecting plate 800 on the first shaping member 80. A three-dimensional scanner 9 is installed in the cavity formed by the first shaping member 80 and the second shaping member 82. The motor 4, the linear module 6, and the three-dimensional scanner 9 are all externally connected to a power source.

[0025] The usage method and advantages of the present utility model: When the external shape of this 3D product is detected, the working process is as follows:

[0026] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the operator places the product to be detected at the central position of the solid disk 100, and then installs the three-dimensional scanner 9 in the installation component 8. The installation process is as follows:

[0027] The operator first loosens the bolt 85 so that the second shaping member 82 can slide to one side from the first shaping member 80. The operator places the three-dimensional scanner 9 in the first shaping member 80, and then pushes the second shaping member 82 closer to the first shaping member 80. At this time, the sliding groove 83 slides on the slider 81. After the first shaping member 80 and the second shaping member 82 are clamped together, the operator tightens the bolt 85 to connect the first shaping member 80 and the slider 81, so that the three-dimensional scanner 9 can be positioned in the installation component 8. Through the above description, the operator can quickly place and remove the three-dimensional scanner 9 in the installation component 8. At the same time, the three-dimensional scanner 9 is positioned in the installation component 8, which can also avoid the situation of shaking during its detection process;

[0028] After the three-dimensional scanner 9 is placed in the installation component 8, the operation steps for the operator to detect the external shape of the 3D product to be detected are as follows:

[0029] Turn on the switches of the positioning component 2, the linear module 6, and the three-dimensional scanner 9. The rotation of the motor 4 drives the gear 5 to rotate. The rotation of the gear 5 makes it rotate around the gear ring 101. The rotation of the gear 5 makes the placement plate 20 rotate, and at the same time makes the linear module 6, the installation component 8, and the three-dimensional scanner 9 rotate synchronously. At this time, the three-dimensional scanner 9 can detect the 3D product to be detected in a circle. At the same time, the operator can also make the position of the three-dimensional scanner 9 convenient for detecting the 3D product to be detected by raising and lowering the linear module 6 according to the height of the 3D product to be detected. Through the provided rotating mechanism, the three-dimensional scanner 9 can rotate and lift, so that the three-dimensional scanner 9 can accurately, continuously, and flexibly detect the 3D printed product. At the same time, the connecting rods 3 provided on two adjacent positioning components 2 are connected to the top of the linear module 6, which is mainly set to ensure the stability of the rotating mechanism during lifting and rotation.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
