Description

[0026] Example
[0027] like Figure 1 , 2 As shown in Figure 3, the food specific volume analyzer based on 3D scanning in this embodiment includes a chassis 1. A transparent detection stage 2 is provided in the middle of the chassis 1. An upper support 3 and a lower support 4 are provided above and below the detection stage 2, respectively. An automatic rotary drive assembly is provided inside the chassis 1. An upper scanning component and a lower scanning component are rotatably mounted on the side of the upper support 3 and the lower support 4 that are close to each other. The automatic rotary drive assembly is connected to the upper scanning component and the lower scanning component, respectively, and is used to drive the upper scanning component and the lower scanning component to rotate in the horizontal plane.
[0028] The usage process of the food specific volume analyzer based on 3D scanning in this embodiment is as follows:
[0029] The object to be tested, D (such as steamed buns or bread), is placed in the middle area of the upper part of the testing platform 2. Then, the automated rotary drive assembly drives the upper and lower scanning components to rotate synchronously. The upper scanning component performs a rotational scanning image of the upper half of the object, while the lower scanning component performs a rotational scanning image of the lower half. The images are then compiled and a 3D model is created to obtain the object's dimensions and calculate its volume. Combined with the object's weight data, the specific volume information is calculated. The overall structure is simple and reasonable, enabling efficient and comprehensive analysis of food volume, significantly improving work efficiency, and meeting the requirements of testing and storage laboratories in the food processing industry, including for steamed buns and pastries.
[0030] In a preferred embodiment, a host 5 with a display screen is mounted on one side wall of the chassis 1, and the automated rotary drive assembly, the upper scanning assembly and the lower scanning assembly are respectively connected to the host 5.
[0031] In the above implementation scheme, the host 5 can control the operation of the automated rotary drive assembly and aggregate the image information acquired by the upper and lower scanning components. Then, it uses the 3D modeling software (existing software) pre-installed in the host 5 to create a model and obtain relevant volume information. Finally, it calculates the specific volume information of the object being tested based on its weight. The host 5 achieves fully automated operation of driving, acquisition, and modeling.
[0032] In this embodiment, light sources 6 are respectively provided around the top and bottom of the detection platform 2, and the light sources 6 are connected to the host 5. The host 5 controls the operation of the light sources 6 to provide supplementary lighting for the object being tested, ensuring that the acquired image information is clear. The light source 6 above the detection platform 2 can be mounted on the lower end of the upper bracket 3 or below the top wall of the chassis 1, and the light source 6 below can be mounted on the lower end of the detection platform 2 or on the side wall of the chassis 1.
[0033] In this embodiment, the light source 6 can be a commercially available textured light of a compatible model.
[0034] Generally, both the upper bracket 3 and the lower bracket 4 are rectangular plate-shaped brackets, and the light source 6 is installed at both ends of the upper bracket 3 and the lower bracket 4 on the side closest to each other.
[0035] In this embodiment, a door 21 that can be opened or closed is provided on any side wall of the chassis 1 at a position corresponding to the detection table 2. This facilitates opening the door 21 to insert or remove the object to be tested.

[0037] In the above implementation scheme, the automated rotary drive assembly can drive the upper cross mounting bracket 71 to rotate. The first camera 72 will take a picture at the initial position of rotation and when it rotates to 30 degrees and 60 degrees. That is, the upper scanning component takes a total of three sets of 12 pictures, which are combined with the image information collected by the lower scanning component to perform accurate 3D modeling.
[0038] In a preferred embodiment, the lower scanning assembly includes a lower cross mount 81 and four second cameras 82. The lower center of the lower cross mount 81 is rotatably connected to the center of the lower support 4 via a second shaft. The automated rotary drive assembly is connected to the second shaft. The four second cameras 82 are respectively mounted on the upper part of the four ends of the lower cross mount 81, and the second cameras 82 are respectively connected to the host 5.
[0039] In the above implementation scheme, the automated rotary drive assembly can drive the lower cross mounting bracket 81 to rotate. The second camera 82 will take a picture at the initial position of rotation and at 30 degrees and 60 degrees. That is, the lower scanning component takes a total of three sets of 12 pictures, which are combined with the image information collected by the upper scanning component to perform accurate 3D modeling.
[0040] In a preferred embodiment, the aforementioned automated rotary drive assembly includes a first main pulley 91, a first auxiliary pulley 92, a first synchronous belt 93, a first coupling 94, a second main pulley 95, a second auxiliary pulley 96, a second synchronous belt 97, and an electrically controlled rotary drive mechanism 98.

The first auxiliary pulley 92 is coaxially mounted on the upper end of the first connecting shaft 94, and the second auxiliary pulley 96 is coaxially mounted on the lower end of the first connecting shaft 94. The first synchronous belt 93 surrounds the first main pulley 91 and the first auxiliary pulley 92, and the second synchronous belt 97 surrounds the second main pulley 95 and the second auxiliary pulley 96. The electrically controlled rotary drive mechanism 98 is connected to the lower end of the first connecting shaft 94 and is connected to the main unit 5.
[0041] In the above implementation scheme, the electrically controlled rotary drive mechanism 98 drives the first coupling shaft 94 to rotate, which in turn drives the first auxiliary pulley 92 and the second auxiliary pulley 96 to rotate synchronously. This, in turn, drives the first main pulley 91 and the second main pulley 95 to rotate via the first synchronous belt 93 and the second synchronous belt 97, respectively. Ultimately, this achieves the rotation of the upper scanning component and the lower scanning component, and the two sets of scanning components are linked together. The driving method is cleverly designed.
[0042] In this embodiment, the electrically controlled rotary drive mechanism 98 is a servo motor.

The support feet are made of rubber, which provides a certain degree of anti-slip and shock absorption.
