[0037] like Figure 1-Figure 3As shown, in this embodiment, a sample measuring device includes a fixed frame 1, an industrial camera 2, a positioning member 3, a clamping assembly 4, and a transmission assembly 5. The industrial camera 2 is arranged on the fixed frame 1, the positioning member 3 is located below the industrial camera 2, and the positioning member 3 is slidably arranged on the fixed frame 1. The positioning member 3 is used to place a truffle sample. The clamping assembly 4 is located between the industrial camera 2 and the positioning member 3, and the clamping assembly 4 is rotatably arranged on the fixed frame 1. The clamping assembly 4 is used to clamp or release the truffle sample on the positioning member 3. The transmission assembly 5 includes a driving mechanism 51, a turntable 52, and a connecting rod 53. The driving mechanism 51 is arranged on the fixed frame 1 and is in transmission connection with the turntable 52. The turntable 52 is connected to the clamping assembly 4. One end of the connecting rod 53 is connected to the turntable 52, and the other end of the connecting rod 53 is connected to the clamping assembly 4. The clamping assembly 4 can rotate relative to the fixed frame 1 under the action of the driving mechanism 51, and the positioning member 3 can slide relative to the fixed frame 1 in the vertical direction. Specifically, an industrial camera 2 is installed on the top of the fixed frame 1, and the industrial camera 2 is used to measure the quality of the appearance of the truffle sample. Along the vertical direction of the fixed frame 1, a clamping assembly 4 and a positioning member 3 are sequentially arranged below the industrial camera 2. The positioning member 3 can slide with the fixed frame 1 in the vertical direction and is used to place the truffle sample. The clamping assembly 4 can rotate relative to the fixed frame 1, and the clamping assembly 4 can clamp the truffle sample on the positioning member 3 and flip it. The fixed end of the driving mechanism 51 is installed on the fixed frame 1, and the output end of the driving mechanism 51 is in transmission connection with the turntable 52. The rotating end of the clamping assembly 4 is connected to the center position of the turntable 52. One end of the connecting rod 53 is arranged at an eccentric position of the turntable 52, and the other end is connected to the clamping assembly 4.

[0038] The sample measurement device operates as follows: a truffle sample is placed on the positioning member 3. The clamping assembly 4 clamps the truffle sample on the positioning member 3 so that the truffle sample is centered on the positioning member 3, making it convenient for the industrial camera 2 to measure it. The clamping assembly 4 then releases the truffle sample, and the industrial camera 2 photographs and measures the truffle sample. After the first stage of measurement is completed, the clamping assembly 4 clamps the truffle sample again, and the drive mechanism 51 is activated. The turntable 52 rotates relative to the fixed frame 1 under the driving action of the drive mechanism 51. The turntable 52 drives the clamping assembly 4 to rotate synchronously, that is, the clamping assembly 4 flips the truffle sample. At the same time, the turntable 52 drives the connecting rod 53 to swing, causing the connecting rod 53 to drive the positioning member 3 to slide vertically relative to the fixed frame 1. As the turntable 52 rotates one revolution, the positioning member 3 slides vertically, first downward and then upward. Simultaneously, the truffle sample flips 180 degrees within the grip of the clamping assembly 4. The clamping assembly 4 then releases the truffle sample, which is then photographed and measured again using the industrial camera 2. After the measurement is complete, the truffle sample is removed from the positioning member 3. This allows for a comprehensive measurement of the truffle sample's appearance without manual intervention, ensuring that the truffle's appearance and quality are not affected. Furthermore, during the flipping process, the positioning member 3, driven by the transmission assembly 5, perfectly avoids collisions with the clamping assembly 4, preventing collisions.

[0039] Further, continue to refer to Figure 1-Figure 3 The turntable 52 includes a turntable body 521, a first gear portion 522, and a second gear portion 523. The diameter of the first gear portion 522 is larger than the diameter of the second gear portion 523. The first gear portion 522 is arranged on the clamping assembly 4, and the second gear portion 523 is arranged on the turntable body 521. The second gear portion 523 is rotatably arranged with the first gear portion 522, and the second gear portion 523 and the first gear portion 522 are both connected to the driving mechanism 51 in a transmission manner. Specifically, the first gear portion 522 and the second gear portion 523 are rotatably matched through bearings. The first gear portion 522 is a large gear, and the second gear portion 523 is a small gear. When the large gear drives the clamping assembly 4 to rotate 180 degrees, it is ensured that the small gear can drive the positioning member 3 to slide downward and then upward in the vertical direction through the connecting rod 53. During the flipping process of the truffle sample, the positioning member 3 perfectly avoids the clamping assembly 4 under the action of the turntable 52 to prevent collision.

[0040] Further, continue to refer to Figure 1-Figure 3The driving mechanism 51 includes a first driving source 511, a first rack 512, and a second rack 513. The first driving source 511 is disposed on the fixed frame 1. The first rack 512 and the second rack 513 are both disposed at the driving end of the first driving source 511. The first rack 512 is meshedly connected to the first gear portion 522, and the second rack 513 is meshedly connected to the second gear portion 523. Specifically, the first driving source 511 is an electric drive. The first rack 512 and the second rack 513 are disposed in parallel. When the first driving source 511 is started, the output end of the first driving source 511 drives the first rack 512 and the second rack 513 to move linearly along the length direction. The first rack 512 drives the first gear portion 522 to rotate, and at the same time, the second rack 513 drives the second gear portion 523 to rotate. The first gear portion 522 drives the clamping assembly 4 to flip the truffle sample. At the same time, the second gear portion 523 drives the turntable 52 to rotate. Under the action of the connecting rod 53, the turntable 52 drives the positioning member 3 to slide in the vertical direction, so that the truffle sample can be flipped and measured in all directions. At the same time, by adopting the engagement of the gear rack and the eccentric setting of the connecting rod 53 and the turntable 52, the positioning member 3 and the clamping assembly 4 can be perfectly avoided to prevent collision.

[0041] Further, continue to refer to Figure 1-Figure 3 The rotation center line of the clamping assembly 4 coincides with the rotation center line of the turntable body 521 , and the rotation center line of the connecting rod 53 at one end of the turntable body 521 is parallel to the rotation center line of the turntable body 521 and does not coincide with it. Specifically, the rotating shaft 42 of the clamping assembly 4 is connected to the center of the turntable 52, and one end of the connecting rod 53 is rotatably connected to the eccentric position or edge of the turntable 52. The first gear portion 522 rotates under the meshing action of the first rack 512, driving the clamping assembly 4 to rotate synchronously, thereby realizing the flipping of the truffle sample. At the same time, the second gear portion 523 rotates under the meshing action of the second rack 513, driving the turntable 52 to rotate synchronously, so that the turntable 52 can drive the connecting rod 53 to swing, and the connecting rod 53 drives the positioning member 3 to slide in the vertical direction, so that when the clamping assembly 4 is flipped to the vertical direction, the positioning member 3 moves downward in the vertical direction to the bottom, and when the clamping assembly 4 continues to flip to the horizontal direction, the positioning member 3 moves upward in the vertical direction to the top to avoid collision.

[0042] Further, continue to refer to Figure 1-Figure 3The sample assay device further includes a guide rod 6. The fixed frame 1 defines a through hole 11 extending vertically. The guide rod 6 is disposed within the through hole 11, and the positioning member 3 is slidably disposed on the guide rod 6. Specifically, the guide rod 6 serves as a guide. The positioning member 3 includes a positioning portion 31 and a sliding portion 32. The sliding portion 32 is connected to the positioning portion 31 and is sleeved on the guide rod 6 and can slide along the length of the guide rod 6, allowing the positioning portion 31 to move up and down in the vertical direction, ensuring that the clamping assembly 4 can be seamlessly replaced on the positioning portion 31 after flipping the clamped truffle assembly.

[0043] Further, continue to refer to Figure 1-Figure 3 The clamping assembly 4 includes a ring 41, a rotating shaft 42, and a clamping member 43. One end of the rotating shaft 42 is connected to the turntable 52, and the other end of the rotating shaft 42 is connected to the ring 41. The clamping member 43 is slidably arranged in the ring 41. There are multiple clamping members 43, and multiple clamping members 43 are spaced apart along the circumferential direction of the ring 41. Multiple clamping members 43 can clamp the truffle sample. Specifically, the clamping member 43 includes a second driving source 431, a push rod 432, and a clamping head 433. The second driving source 431 is arranged on the ring 41. The output end of the second driving source 431 is connected to the push rod 432, and the clamping head 433 is connected to the push rod 432, and the push rod 432 can be pressed against the outer surface of the truffle sample. The second drive source 431 is an electric drive. When the second drive source 431 is started, the push rod 432 is extended, and the push rod 432 drives the clamping head 433 to be pressed against the outer surface of the truffle sample. That is, multiple clamping members 43 clamp the truffle sample in the circumferential direction. Then, the turntable 52 rotates and drives the rotating shaft 42 to rotate synchronously. The rotating shaft 42 drives the ring 41 to flip, thereby achieving the truffle sample clamped by the multiple clamping members 43 provided on the ring 41 to flip, achieving a full measurement of the truffle sample appearance, without manual operation, ensuring that the appearance quality of the truffle is not affected. Similarly, the second drive source 431 is started, and the push rod 432 is shortened. The push rod 432 drives the clamping head 433 to separate from the truffle sample, that is, multiple clamping members 43 release the truffle sample, so that the truffle sample is placed on the positioning member 3, which is convenient for the industrial camera 2 to measure it.

[0044] Further, continue to refer to Figure 1-Figure 3 The clamping member 43 also includes a buffer portion, which is provided on the clamping head 433. Specifically, the buffer portion is made of sponge material and is fixed to the clamping head 433 by bonding. When the clamping member 43 clamps the truffle sample, the buffer portion acts as a buffer and protects the surface of the truffle sample, avoiding damage to the truffle sample, thereby ensuring that the appearance quality of the truffle is not affected.

[0045] Further, continue to refer to Figure 1-Figure 3The sample measuring device further includes a computer, which is electrically connected to the first driving source 511, the second driving source 431, and the industrial camera 2. Specifically, an operator controls the computer, which sends signals to the first driving source 511, the second driving source 431, and the industrial camera 2. The computer controls the start and stop of the first driving source 511 to control the rotation of the turntable 52, thereby achieving the sliding of the positioning member 3 in the vertical direction and the flipping of the clamping assembly 4. At the same time, the computer controls the start and stop of the second driving source 431 to control the clamping head 433 to clamp or separate the truffle sample on the positioning member 3, and the computer controls the industrial camera 2 to photograph and measure the truffle sample.
