Description

Technical Field

[0001] This invention relates to the field of meat product testing, and more specifically, to a testing device and method for meat products. Background Technology

[0002] As people's living standards improve, their requirements for food safety and quality are becoming increasingly stringent, especially for meat products. During the processing of meat products, the color of the meat and internal foreign objects (such as metal and bone fragments) are important factors affecting their quality and safety.

[0003] When problematic meat pieces are detected, manual identification and sorting are often required. This not only increases labor costs but also easily causes process interruptions on the production line, reducing overall production efficiency. Furthermore, existing marking methods may suffer from problems such as unclear markings, easy detachment, or secondary contamination of the meat pieces. For example, simple inkjet markings may be washed away, or the marking position may be inaccurate. Therefore, we propose a detection device and method for meat products. Summary of the Invention

[0004] This invention provides a detection device and method for meat products, solving the technical problems of marking methods in related technologies, such as unclear marking, easy detachment, or secondary contamination of meat.

[0005] The first aspect of the present invention provides a testing device for meat products, comprising: a testing chamber, wherein a high-intensity camera, an X-ray detector and a labeling mechanism are sequentially arranged inside the testing chamber along the direction in which meat blocks are transported by a conveyor belt;

[0006] The tag insertion mechanism includes a tag insertion robotic arm, a tag insertion tube, a tag storage box, and a tag pushing component. The tag insertion tube is located at the end of the tag insertion robotic arm. Multiple tag storage boxes are fixedly installed on the outer wall of the tag insertion tube. Each tag storage box is filled with several javelins. The javelins in the same tag storage box are of the same color. The tag pushing component is located inside the tag insertion tube.

[0007] The high-brightness camera is used to capture the color of the meat surface, and the X-ray inspection machine is used to detect the precise location of metal and bone fragments in the meat. The inspection room is also equipped with a system processing unit, which is used to calculate and process the detection data from the high-brightness camera and the X-ray inspection machine.

[0008] The meat chunks pass sequentially on the conveyor belt through a high-intensity camera, an X-ray inspection machine, and a labeling robotic arm. The system processing unit calculates and processes the detection data, controls the labeling robotic arm to align the labeling tube with and approach the position on the meat chunk that needs to be marked, and then the label pushing component retrieves the required color of the label from the corresponding label storage box into the labeling tube. The label pushing component then precisely inserts the label into the position that needs to be marked, thus achieving automatic detection and marking of the meat chunks.

[0009] Furthermore, the labeling robotic arm is fixed at the material discharge end inside the testing chamber. The high-intensity camera, X-ray inspection machine, and labeling robotic arm are all interconnected with the testing chamber's system and controlled by the system.

[0010] Furthermore, the label pushing assembly includes a label pressing plate, on the lower wall of which a rotating component and an electromagnetic telescopic column are fixedly installed. The rotating component is located at the center of the label pressing plate, and the electromagnetic telescopic column is located on one side of the rotating component. The diameter of the label pressing plate is the same as the inner diameter of the label insertion tube, and the label pressing plate is rotatably located inside the label insertion tube.

[0011] Furthermore, a limit block is fixedly provided at the rotation output end of the rotating component, and an adjustment plate is rotatably provided on the lower wall of the limit block. The position of the adjustment plate and the rotation axis of the limit block is located at the lower right corner of the limit block. The rotation of the adjustment plate constitutes a rotation from top to bottom, with a rotation angle of 0 to 90°.

[0012] Furthermore, a pull plate screw is fixedly installed at one end of the adjusting plate near the lower right corner of the limit block pivot, and several rope clips are fixedly installed on the side of the rotating part near the electromagnetic telescopic column. The end of the pull plate screw away from the adjusting plate passes around several rope clips and is fixedly connected to the telescopic arm of the electromagnetic telescopic column, which is used to pull the adjusting plate counterclockwise when the telescopic arm retracts.

[0013] Furthermore, an electromagnet is rotatably mounted on one end of the adjusting plate near the inner wall of the pitch tube, and the distance between the magnetic attraction surface of the electromagnet and the inner wall of the pitch tube is greater than the diameter of the javelin. The electromagnet and the adjusting plate rotate clockwise, and an elastic rope is fixedly mounted on the rotating end of the adjusting plate and the electromagnet. A counterweight ball is suspended below the electromagnet, and multiple pull plates are connected between the adjusting plate and the limiting block. These are used to control the electromagnet with the javelin to rotate counterclockwise while the adjusting plate rotates, thus controlling the javelin to move closer to the center of the pitch tube.

[0014] Furthermore, a kinetic energy box is fixedly installed on the upper wall of the label insertion tube, and an electric push rod is fixedly installed inside the kinetic energy box. The telescopic end of the electric push rod passes through the label insertion tube and is fixedly connected to the label pressing plate. It is used to drive the label pressing plate to press down and push the javelin out from the bottom of the label insertion tube to pierce the meat.

[0015] Furthermore, several sling boxes have sling outlets on one side close to the sling tube, and the width of the sling outlets matches the diameter of the javelins. The sling boxes have annular channels inside, and the annular channels are spiral-shaped like mosquito coils. Multiple sling-pushing springs are installed in the annular channels, and the javelins are also loaded in the annular channels to push the javelins out sequentially from the center of the annular channels to the sling outlets.

[0016] Furthermore, the javelin includes a main shaft, with an air storage bag inside the bottom end of the main shaft. Below the air storage bag is a retractable column that is slidably connected to the main shaft. A pointed cone is fixedly installed at the bottom end of the retractable column. An expansion ball that communicates with the air storage bag is fixedly installed at the top end of the main shaft. The expansion ball is colored and is used so that when the javelin pierces the flesh, the gas in the air storage bag is squeezed into the expansion ball through the retractable column, causing it to expand.

[0017] A second aspect of the present invention provides a detection method for a meat product detection device, comprising the following steps:

[0018] S1. The meat block passes through a high-brightness camera and an X-ray inspection machine in sequence via a conveyor belt. The high-brightness camera captures the color image of the surface of the meat block, and the X-ray inspection machine scans the precise location of metal and bone fragments inside the meat block.

[0019] S2. The system processing unit analyzes and calculates the collected color and X-ray data to determine the location and type of marking required for the meat pieces, and distinguishes them using different colored jewels.

[0020] S3. The system controls the movement of the labeling robotic arm, driving the labeling cylinder to align with and approach the position of the meat piece that needs to be marked.

[0021] S4. According to the system instructions, the sling pusher takes out a sling from the sling box of the corresponding color, and introduces and positions it inside the sling insert tube by electromagnet attraction and adjustment plate rotation.

[0022] S5. The electric push rod pushes the pressure plate down, pushing the javelin out from the bottom of the insertion tube and piercing the meat.

[0023] When the javelin pierces the target, its retracting column squeezes the gas storage bag, causing gas to enter the expansion sphere and expand to display color, thus completing the automatic marking.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention achieves a fully automated process from meat detection to labeling by linking a high-brightness camera, an X-ray inspection machine, and a labeling mechanism, which greatly improves production efficiency, reduces manual intervention and errors, and lowers production costs.

[0026] The system processing unit comprehensively processes the data from the high-intensity camera and X-ray detection, which can accurately identify areas of abnormal color in the meat and the precise location of foreign objects inside. It also uses a tagging robotic arm to drive the tagging tube to accurately position the tag, ensuring that the tweezers are accurately pierced into the meat.

[0027] The storage boxes contain javelins of different colors, allowing the system to color-code and mark the samples based on the detection results (such as the type of foreign object, color grade, and severity of defects). This facilitates the rapid sorting, classification, and traceability of different types of problematic meat pieces, improving processing efficiency and accuracy. Attached Figure Description

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0039] Example 1

[0040] like Figure 1 - Figure 9 As shown, a meat product testing device includes: a testing chamber 11, wherein a high-brightness camera 13, an X-ray detector 12 and a labeling mechanism 2 are sequentially arranged inside the testing chamber 11 along the direction of the conveyor belt transporting meat blocks;

[0041] The tag insertion mechanism 2 includes a tag insertion robotic arm 21, a tag insertion cylinder 23, a tag storage box 31, and a tag pushing assembly. The tag insertion cylinder 23 is located at the end of the tag insertion robotic arm 21. Multiple tag storage boxes 31 are fixedly installed on the outer wall of the tag insertion cylinder 23. Each tag storage box 31 is filled with several javelins 41. The javelins 41 in the same tag storage box 31 are of the same color. The tag pushing assembly is located inside the tag insertion cylinder 23.

[0042] The high-brightness camera 13 is used to capture the color of the meat surface, and the X-ray inspection machine 12 is used to detect the precise location of metal and bone fragments in the meat. The inspection chamber 11 is also equipped with a system processing unit, which is used to calculate and process the detection data of the high-brightness camera 13 and the X-ray inspection machine 12.

[0043] The meat chunks pass sequentially on the conveyor belt through the high-intensity camera 13, the X-ray inspection machine 12, and the labeling robotic arm 21. The system processing unit calculates and processes the detection data, controls the labeling robotic arm 21 to drive the labeling cylinder 23 to align with and approach the position on the meat chunk that needs to be marked, and then the label pushing component takes the label 41 of the required color from the corresponding label storage box 31 into the labeling cylinder 23. The label pushing component then precisely inserts the label 41 into the position that needs to be marked, thus realizing the automatic detection and marking of the meat chunks.

[0044] The labeling robotic arm 21 is fixed inside the inspection chamber 11 at the material discharge end. The high-brightness camera 13, the X-ray inspection machine 12, and the labeling robotic arm 21 are all interconnected with the system in the inspection chamber 11 and are controlled by the system.

[0045] The label pushing assembly includes a label pressing plate 25. A rotating component 26 and an electromagnetic telescopic column 27 are fixedly installed on the lower wall of the label pressing plate 25. The rotating component 26 is located at the center of the label pressing plate 25, and the electromagnetic telescopic column 27 is located on one side of the rotating component 26. The diameter of the label pressing plate 25 is the same as the internal diameter of the label insertion cylinder 23, and the label pressing plate 25 is rotatably installed inside the label insertion cylinder 23.

[0046] A limiting block 28 is fixedly installed at the rotation output end of the rotating component 26. An adjusting plate 29 is rotatably installed on the lower wall of the limiting block 28. The position of the adjusting plate 29 and the rotation axis of the limiting block 28 is located at the lower right corner of the limiting block 28. The rotating plate 29 rotates from top to bottom, and the rotation angle is 0 to 90°.

[0047] A pull plate wire 204 is fixedly installed at one end of the adjusting plate 29 near the lower right corner of the pivot of the limiting block 28. Several rope clips 203 are also fixedly installed on the side of the rotating part 26 near the electromagnetic telescopic column 27. The end of the pull plate wire 204 away from the adjusting plate 29 passes around several rope clips 203 and is fixedly connected to the telescopic arm 202 of the electromagnetic telescopic column 27, so as to pull the adjusting plate 29 to rotate counterclockwise when the telescopic arm 202 retracts.

[0048] An electromagnet 205 is rotatably mounted on one end of the adjusting plate 29 near the inner wall of the pitch tube 23. The distance between the magnetic surface of the electromagnet 205 and the inner wall of the pitch tube 23 is greater than the diameter of the javelin 41. The electromagnet 205 and the adjusting plate 29 rotate clockwise. An elastic rope 201 is fixedly mounted on the rotating end of the adjusting plate 29 and the electromagnet 205. A counterweight ball 206 is suspended below the electromagnet 205. Multiple pull plates 207 are also connected between the adjusting plate 29 and the limiting block 28. The electromagnet 205 with the javelin 41 rotates counterclockwise while the adjusting plate 29 rotates, controlling the javelin 41 to move closer to the center of the pitch tube 23.

[0049] A kinetic energy box 22 is fixedly installed on the upper wall of the label insertion tube 23. An electric push rod 24 is fixedly installed inside the kinetic energy box 22. The telescopic end of the electric push rod 24 passes through the label insertion tube 23 and is fixedly connected to the label pressing plate 25. It is used to drive the label pressing plate 25 to press down and push the javelin 41 out from the bottom of the label insertion tube 23 to pierce the meat.

[0050] Several marker boxes 31 have marker outlets 34 on one side close to the marker tube 23, and the width of the marker outlets 34 matches the diameter of the javelins 41. The interior of the marker box 31 is provided with an annular channel 33, which is spiral-shaped like a mosquito coil. Multiple marker pushing springs 35 are provided in the annular channel 33, and the javelins 41 are also loaded in the annular channel 33 for sequentially pushing the javelins 41 from the center of the annular channel 33 toward the marker outlets 34.

[0051] The javelin 41 includes a main shaft 44. An air storage bag 45 is provided inside the bottom end of the main shaft 44. A retraction column 43, which is slidably connected to the main shaft 44, is provided below the air storage bag 45. A pointed cone 42 is fixedly provided at the bottom end of the retraction column 43. An expansion ball 46, which is connected to the air storage bag 45, is fixedly provided at the top end of the main shaft 44. The expansion ball 46 is colored and is used to compress the gas in the air storage bag 45 into the expansion ball 46 through the retraction column 43 when the javelin 41 pierces the meat, causing it to expand.

[0052] Testing phase:

[0053] The meat chunks pass sequentially through a high-intensity light camera 13 and an X-ray inspection machine 12 via a conveyor belt. The high-intensity light camera 13 captures color images of the surface of the meat chunks to identify areas with uneven color, spoilage, or contamination. The X-ray inspection machine 12 scans the meat chunks to detect the precise location of foreign objects such as metal and bone fragments inside. The system processing unit processes the detection data from the high-intensity light camera 13 and the X-ray inspection machine 12 in real time, calculates the locations and types of markings that need to be made, and distinguishes them using different colored tweezers 41.

[0054] Marking stage:

[0055] The system processing unit controls the movement of the label-inserting robotic arm 21, causing the label-inserting cylinder 23 to align with and approach the location on the meat piece that needs to be marked. According to system instructions, the label-pushing assembly retrieves a jewel 41 from the corresponding color label storage box 31 and introduces it into the label-inserting cylinder 23. The label-pressing plate 25 in the label-pushing assembly is pressed down by the electric push rod 24, pushing the jewel 41 out from the bottom of the label-inserting cylinder 23 and precisely inserting it into the designated location on the meat piece.

[0056] When the javelin 41 pierces the meat, its pointed tip 42 contacts the meat, and the retracting column 43 slides upward, squeezing the gas storage bag 45 and allowing gas to enter the expansion ball 46. The expansion ball 46 expands and displays color, thus forming a clear mark on the surface of the meat, facilitating subsequent manual or automated processing.

[0057] Detailed workflow of the pusher component:

[0058] When it is necessary to pick up the tag, the tag pressing plate 25 drives the electromagnet 205 to rotate to the position of the tag storage box 31 of the specified color through the rotating part 26. Then, the electromagnet 205 is controlled to work to pick up the dart 41 located at the tag outlet 34 and fix it tightly to the adsorption surface of the electromagnet 205.

[0059] Then the telescopic arm 202 of the electromagnetic telescopic column 27 retracts, and the adjusting plate 29 is pulled counterclockwise by the pull plate wire 204 around the rope buckle 203. At the same time, it rotates under the gravity of the counterweight ball 206 and the tension of the elastic rope 201, so that the electromagnet 205 on the adjusting plate 29 is aligned with the mark outlet hole of the mark box 31.

[0060] Finally, the electric push rod 24 pushes the pressure plate 25 down, pushing the javelin 41 out of the tassel insertion tube 23 and into the meat. At this time, the javelin 41 has not completely detached from the electromagnet 205, but has already pierced into the meat. At this time, the electromagnet 205 stops working, releasing the javelin 41. The tassel insertion robotic arm 21 rises and moves, and the javelin 41 completely detaches from the tassel insertion tube 23.

[0061] Then the electromagnetic telescopic column 27 extends, and the adjustment plate 29 is reset under the action of the pull plate belt 207.

[0062] The bidding mechanism of the bidding box 31:

[0063] The storage box 31 has an annular channel 33 inside, in which the javelins 41 are loaded. The javelins 41 are continuously pushed by the javelin spring 35, which moves the javelins 41 from the center to the javelin outlet 34, ensuring a continuous supply of javelins 41. The side of the storage box 31 is also provided with a javelin box door 32 for loading the javelins 41.

[0064] High efficiency and automation: Through the linkage of high-brightness camera 13, X-ray inspection machine 12 and labeling mechanism 2, a fully automated process from meat block detection to labeling is realized, which greatly improves production efficiency and reduces manual intervention and errors.

[0065] Precise positioning: The system processing unit comprehensively processes color and X-ray data, which can accurately identify the problem area and drive the labeling cylinder 23 to accurately position it through the labeling robotic arm 21, ensuring the accurate marking position.

[0066] Multi-color marking: The label box 31 contains different colored javelins 41, which can be color-coded according to the test results, such as the type of foreign object and the color grade, to facilitate subsequent sorting or processing.

[0067] Flexible label picking: Multiple label storage boxes 31 are set on the outer wall of the label tube 23, and the label pushing component can flexibly pick up different colored labels 41 through electromagnet 205 to adapt to various marking needs.

[0068] Stable javelin ejection: The javelin ejection assembly uses a combination of a pressure plate 25 and an electric push rod 24 to ensure that the javelin 41 is ejected smoothly and powerfully, avoiding marking failure or deviation.

[0069] Clear marking: After the javelin 41 pierces the meat, the expansion ball 46 expands and displays color, forming a conspicuous mark that is easy to identify with the naked eye or captured by machine vision.

[0070] Reduced damage: The design of the pointed cone 42 and the retractable column 43 ensures that the force is evenly distributed when the javelin 41 penetrates, and the air reservoir 45 is compressed and then expanded to avoid excessive damage to the meat.

[0071] Example 2

[0072] A detection method for a meat product detection device includes the following steps:

[0073] S1. The meat block passes through the high-brightness camera 13 and the X-ray inspection machine 12 in sequence via the conveyor belt. The high-brightness camera 13 captures the color image of the surface of the meat block, and the X-ray inspection machine 12 scans the precise location of metal and bone fragments inside the meat block.

[0074] S2. The system processing unit analyzes and calculates the collected color and X-ray data to determine the location and type of marking required for the meat pieces, and distinguishes them using different colored jewels 41.

[0075] S3. The system controls the labeling robotic arm 21 to move, driving the labeling cylinder 23 to align with and approach the position of the meat piece that needs to be marked.

[0076] S4. According to the system instructions, the pusher component takes out a javelin 41 from the corresponding color storage box 31, and introduces and positions it inside the insert tube 23 by the attraction of the electromagnet 205 and the rotation of the adjustment plate 29.

[0077] S5, the electric push rod 24 pushes the pressure plate 25 down, pushing the javelin 41 out from the bottom of the insertion tube 23 and piercing the meat;

[0078] When the javelin 41 pierces the air, its retracting column 43 squeezes the gas storage bag 45, causing the gas to enter the expansion ball 46 and expand to display color, thus completing the automatic marking.

[0079] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.

Multiple tag pushing springs (35) are provided in the annular channel (33), and the dart (41) is also loaded in the annular channel (33) for sequentially pushing the dart (41) from the center of the annular channel (33) to the tag outlet (34).

7. The detection device for meat products according to claim 6, characterized in that, The javelin (41) includes a main shaft (44), with an air storage bag (45) inside the bottom end of the main shaft (44). Below the air storage bag (45) is a retractable column (43) that is slidably connected to the main shaft (44). A pointed cone (42) is fixedly provided at the bottom end of the retractable column (43). An expansion ball (46) that communicates with the air storage bag (45) is fixedly provided at the top end of the main shaft (44). The expansion ball (46) is colored and is used to squeeze the gas in the air storage bag (45) into the expansion ball (46) through the retractable column (43) when the javelin (41) pierces the meat, causing it to expand.

8. A detection method using the detection device for meat products as described in claim 7, characterized in that, Includes the following steps: S1. The meat block passes through a high-brightness camera (13) and an X-ray inspection machine (12) in sequence via a conveyor belt. The high-brightness camera (13) captures the color image of the surface of the meat block, and the X-ray inspection machine (12) scans the precise location of metal and bone fragments inside the meat block. S2. The system processing unit analyzes and calculates the collected color and X-ray data to determine the location and type of marking required for the meat pieces, and distinguishes them using different colored jewels (41). S3. The system controls the movement of the labeling robotic arm (21), which drives the labeling cylinder (23) to align with and approach the position of the meat piece that needs to be marked. S4. According to the system instructions, the trolley component takes out a trolley (41) from the corresponding color trolley box (31), and introduces and positions it inside the trolley tube (23) by the attraction of the electromagnet (205) and the rotation of the adjustment plate (29). S5. The electric push rod (24) pushes the pressure plate (25) down, pushing the javelin (41) out from the bottom of the insertion tube (23) and piercing the meat. When the javelin (41) pierces the air, its retracting column (43) squeezes the gas storage bag (45), causing the gas to enter the expansion ball (46) and expand to display color, thus completing the automatic marking.
