Description

Technical Field

[0001] The present invention relates to the technical field of multispectral detection, and in particular to a multispectral infrared imaging non-destructive grading detection device and method for beef cattle carcasses. Background Art

[0002] Accurately assessing the quality and grade of beef carcasses can provide a scientific basis for the pricing, processing, and sales of beef products. This test often uses multispectral infrared imaging technology, employing a spectrometer, a detection integration, and a conveyor device for beef carcasses. The conveyor belt of the conveyor device drives the beef carcasses to be tested through the underside of the spectrometer and the detection integration for testing. However, the sizes and shapes of the multiple beef carcasses to be tested placed on the conveyor belt are unlikely to be exactly the same. It is difficult to ensure that the light source height is consistent with the sample surface position during each spectral analysis, which affects the accuracy of the test results. In addition, the detection position for the same beef carcass is relatively single, reducing the accuracy of the test results. Summary of the Invention

[0014] Preferably, the water removal assembly includes a second telescopic rod fixed to the inner top wall of the light shield, a guide plate arranged on the lower side of the second telescopic rod, a winding rod arranged at both ends of the guide plate, and a water-absorbing cloth arranged between the two winding rods.

[0018] The present invention also discloses a method for non-destructive grading and detection of beef cattle carcasses using multi-spectral infrared imaging, which is performed by using a non-destructive grading and detection device for beef cattle carcasses using multi-spectral infrared imaging, and further includes the following steps:

[0019] S1: Place the beef cattle carcass to be inspected on the conveyor belt, start the belt conveyor and water supply equipment, and the beef cattle carcass moves along the conveyor belt to the inspection area inside the light shield. During this process, the nozzle of the flushing mechanism sprays water at an inclined angle to flush away the minced meat and impurities on the surface of the beef cattle carcass;

[0020] S2: After the beef cattle carcass enters the light shield, it first presses against the second inclined surface of the guide plate. The guide plate is forced upward, the second telescopic rod contracts, and the reel motor drives the reel rods to rotate. One reel rod releases the absorbent cloth while the other reel reels it. This drives the absorbent cloth to dynamically absorb the remaining water droplets on the beef cattle carcass. The tension rod maintains constant tension in the absorbent cloth through the elastic telescopic plate.

[0021] S3: When the reeling rod rotates, the crankshaft is driven to rotate via the second synchronous wheel and the second synchronous belt. When the crankshaft rotates, the lifting rod is driven to move up and down via the swing rod. When the lifting rod moves, the elastic telescopic rod and the pressure rod are driven to move up and down, so that the pressure rod presses down the absorbent cloth. The absorbent cloth can be in close contact with the surface of the beef cattle, so that the absorbent cloth can fully absorb the moisture on the surface of the beef cattle;

[0022] S4: After the water droplets are removed, the carcass of the beef cattle is moved to the guide frame. The first inclined surface of the guide frame is forced upward, causing the detection integrated on the guide frame to automatically adjust its height to adapt to the height difference of the beef cattle carcass surface. The incident light source is split by the filter and illuminates the carcass. The diffuse reflection optical fiber collects the reflected spectrum signal. The spectrometer collects data at a frequency of 10 times per second.

[0023] S5: When the belt conveyor is working, one of the conveying rollers drives the reciprocating screw to rotate through the first synchronous wheel and the first synchronous belt, and the sleeve drives the guide frame to move back and forth along the axial direction of the reciprocating screw through the first telescopic rod, so that the detection integration can detect different positions of the same beef cattle carcass. After detection, the beef cattle carcass is removed from the outlet of the light shield and enters the next processing step.

[0024] Compared with the existing technology, the present invention provides a multi-spectral infrared imaging non-destructive grading and detection device and method for beef cattle carcasses, which has the following beneficial effects:

[0025] 1. This multispectral infrared imaging nondestructive grading and inspection equipment and method for beef cattle carcasses uses a first inclined surface design on the guide frame to achieve adaptive adjustment of the detection integration height, tracking the carcass curved surface in real time. The reciprocating screw of the displacement assembly is mechanically linked to the conveyor roller via a first synchronous wheel, allowing inspection at multiple locations on the same carcass. This eliminates optical path errors caused by differences in carcass morphology, avoids excessive spectral signal attenuation errors, and ensures the accuracy of inspection results.

[0026] 2. This multispectral infrared imaging non-destructive grading and testing equipment and method for beef cattle carcasses uses a flushing mechanism to spray high-pressure water at a 30-degree angle to remove meat scraps. The absorbent cloth of the water removal component is dynamically pressed against the carcass surface by a pressure rod, increasing its water absorption rate and preventing abnormal fluctuations in spectral reflectance caused by residual meat scraps and moisture, further improving the accuracy of test results.

[0027] 3. The multi-spectral infrared imaging non-destructive grading and detection equipment and method for beef cattle carcasses improve the anti-interference ability of the detection equipment through a two-stage pretreatment of flushing and water absorption and light-shielding environment control.

[0028] 4. This multi-spectral infrared imaging non-destructive grading and inspection equipment and method for beef cattle carcasses uses synchronous belt drive to reduce drive power consumption and self-circulating absorbent cloth to reel in and absorb water, thereby improving the continuity of beef cattle carcass inspection work and enhancing inspection efficiency.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figures 1 to 3As shown, this embodiment proposes a multispectral infrared imaging non-destructive grading and inspection device for beef cattle carcasses, comprising a frame 1, and further comprising: a belt conveyor 2 for conveying beef cattle carcasses, a flushing mechanism for flushing minced meat on the surface of the beef cattle carcasses, and a light shield 3. The belt conveyor 2 is arranged on the frame 1, the flushing mechanism is arranged on the frame 1 and is placed at the front end of the belt conveyor 2, the light shield 3 is fixed to the frame 1, and the front and rear sides of the light shield 3 are both provided with openings, and light shielding curtains 301 are provided at the openings. The light shield 3 contains an infrared detection component for detecting the quality of the beef cattle carcasses, a displacement component for driving the displacement of the infrared detection component, and a water removal component for removing residual water droplets after the flushing mechanism flushes the beef cattle carcasses. The water removal component is arranged at the front end of the infrared detection component.

[0043] The beef cattle carcass to be inspected is placed on the belt conveyor 2, and the beef cattle carcass moves along the belt conveyor 2 to the inspection area in the light shield 3. During this process, the water flow sprayed by the flushing mechanism sprays water at an inclined angle to flush the minced meat and impurities on the surface of the beef cattle carcass. The flushed minced meat and impurities fall from the front end of the belt conveyor 2. After the beef cattle carcass enters the light shield 3, it will pass through the dewatering component and the infrared detection component in sequence. The light shield 3 blocks the external ambient light, and the dewatering component removes moisture from the surface of the beef cattle carcass. Then the infrared detection component detects the beef cattle carcass with a clean surface. The infrared detection component can adapt to the surface height differences of carcasses of different sizes, solves the optical path error caused by differences in carcass morphology, avoids excessive spectral signal attenuation error, and ensures the accuracy of the detection results.

[0044] like Figure 1 and Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, the belt conveyor 2 further includes a plurality of conveyor rollers 201 rotatably connected to the frame 1, a conveyor belt 202 slidingly connected to the plurality of conveyor rollers 201, and a conveying motor connected to the frame 1 and used to drive one of the conveyor rollers 201 to rotate; the belt conveyor 2 is a prior art. When the belt conveyor 2 is started, the conveying motor is controlled to run, so that the conveying motor drives one of the conveyor rollers 201 to rotate, and the remaining conveyor rollers 201 rotate together with the conveyor belt 202, so that the conveyor belt 202 conveys and inspects the beef carcass.

[0045] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, as a preferred embodiment, on the basis of the above method, further, the infrared detection component includes a spectrometer 4 fixed on the top of the light shield 3 and a detection integration 5 connected to the spectrometer 4 through a wire, and the detection integration 5 includes an incident light source, a diffuse reflection optical fiber and a filter; the incident light source of the detection integration 5 is split by the filter and then illuminates the carcass on the lower conveyor belt 202, the diffuse reflection optical fiber collects the reflected spectrum signal, the spectrometer 4 collects data at a frequency of 10 times per second, and the spectrometer 4 and the detection integration 5 adopt the existing conventional multi-spectral infrared imaging detection component.

[0046] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the displacement assembly includes a reciprocating screw 6 rotatably connected to the light shield 3, a sleeve 601 threadedly connected to the reciprocating screw 6, a first telescopic rod 602 connected to the sleeve 601, and a guide frame 603 arranged on the lower side of the first telescopic rod 602, and both sides of the guide frame 603 near the front end of the belt conveyor 2 are set as first inclined surfaces, and the detection integration 5 is arranged on the upper side of the guide frame 603;

[0047] The beef cattle carcass moves along the conveyor belt 202 to the detection area in the light shield 3, and the beef cattle carcass moves to the guide frame 603. The first inclined surface of the guide frame 603 is forced to move upward, so that the detection integration 5 on the guide frame 603 automatically adjusts the height to adapt to the height difference of the beef cattle carcass surface, solves the optical path error caused by the difference in carcass morphology, avoids excessive error in spectral signal attenuation, and ensures the accuracy of the detection result. When the displacement component is working, the reciprocating screw 6 rotates, and the sleeve 601 drives the guide frame 603 to reciprocate along the axial direction of the reciprocating screw 6 through the first telescopic rod 602. The reciprocating screw 6 is movably provided with a sliding member that slides with the top of the light shield 3. The connected auxiliary block 6011 is used to limit the movement direction of the sleeve 601 while improving the stability of the sleeve 601's support for the guide frame 603. This allows the detection system 5 to inspect different locations on the same beef cattle carcass, further improving the accuracy of the carcass inspection results. The side surface 6031 of the guide frame 603 on the first inclined surface should be designed as a curved or inclined surface to reduce the resistance between the guide frame 603 and the beef cattle carcass during axial movement along the reciprocating screw 6. The reciprocating screw 6 has two reciprocating threads, and the sleeve 601 has two reciprocating threads. Each sleeve 601 is engaged with a reciprocating thread, ensuring smoother movement of the guide frame 603. The auxiliary block 601 is fixed to one of the sleeves 601.

[0048] It should be noted that in order to reduce driving power consumption and driving cost, the reciprocating screw 6 and one of the conveying rollers 201 of the belt conveyor 2 placed in the light shield 3 are both provided with a first synchronous wheel 7, and a first synchronous belt is provided between the two first synchronous wheels 7. When the conveying roller 201 rotates, the reciprocating screw 6 is driven to rotate through the first synchronous wheel 7 and the first synchronous belt, so that the displacement component is activated.

[0049] like Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the water removal assembly includes a second telescopic rod 8 fixedly mounted on the inner top wall of the light shield 3, a guide plate 9 arranged on the lower side of the second telescopic rod 8, a winding rod 901 arranged at both ends of the guide plate 9, and a water-absorbing cloth 902 arranged between the two winding rods 901, and the side of the guide plate 9 close to the front end of the belt conveyor 2 is set as a second inclined surface, and a winding motor for driving the winding rod 901 to rotate is provided in the guide plate 9;

[0050] The beef cattle carcass moves toward the detection area inside the light shield 3 along with the conveyor belt 202. After entering the interior of the light shield 3, the beef cattle carcass will first squeeze the second inclined surface of the guide plate 9. The guide plate 9 is forced to move upward, and the second telescopic rod 8 contracts. The winding motor drives the winding rod 901 to rotate. One of the winding rods 901 releases the absorbent cloth 902, and the other winding rod 901 winds up the absorbent cloth 902, driving the absorbent cloth 902 to dynamically absorb the water droplets remaining on the beef cattle carcass, ensuring the continuous water absorption performance of the absorbent cloth 902 on the water droplets on the surface of the beef cattle carcass. It should be noted that the guide plate 9 is configured as a V-shaped plate, and the winding rod 901 is rotatably set in the working groove opened on its bottom plate.

[0051] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 9 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, support plates 10 are fixedly provided at both ends of the guide plate 9, a crank shaft 11 is rotatably connected to the support plate 10, a second synchronous wheel 12 is provided on the crank shaft 11 and the winding rod 901, a second synchronous belt is provided between the two second synchronous wheels 12, a swing rod 13 is movably connected to the crank shaft 11, and an end of the swing rod 13 away from the crank shaft 11 is movably connected to a lifting rod 14, and a plurality of elastic telescopic rods 141 are provided on the lifting rod 14, and a pressure rod 142 is provided at the bottom of each elastic telescopic rod 141 for movably resisting the top of the absorbent cloth 902;

[0052] Furthermore, an elastic expansion plate 15 is fixedly provided on the guide plate 9, and a tensioning rod 151 is movably connected to the elastic expansion plate 15 and movably abuts against the bottom of the absorbent cloth 902;

[0053] When the reeling rod 901 rotates, the crankshaft 11 is driven to rotate via the second synchronous wheel 12 and the second synchronous belt. When the crankshaft 11 rotates, the lifting rod 14 is driven to move up and down reciprocatingly via the swing rod 13. When the lifting rod 14 moves, it drives the elastic telescopic rod 141 and the pressure rod 142 to move up and down, so that the pressure rod 142 presses down the absorbent cloth 902. The absorbent cloth 902 can be in close contact with the surface of the beef cattle, so that the absorbent cloth 902 can fully absorb the moisture on the surface of the beef cattle, thereby improving the water absorption rate of the absorbent cloth 902, avoiding abnormal fluctuations in spectral reflectance caused by residual minced meat and moisture, and further improving the accuracy of the detection results; the tensioning rod 151 maintains a constant tension in the absorbent cloth 902 through the elastic telescopic plate 15;

[0054] Furthermore, U-shaped plates 17 are fixed to both ends of the guide plate 9, and electric push rods 171 are provided at both ends of the U-shaped plate 17. An arc-shaped pressure plate 172 is provided at the end of each electric push rod 171 away from the U-shaped plate 17. The winding rod 901 is placed between the two arc-shaped pressure plates 172 of the same U-shaped plate 17, and a filter hole is opened on the lower arc-shaped pressure plate 172.

[0055] After a roll of absorbent cloth 902 is wound up, the staff controls the electric push rod 171 on the U-shaped plate 17 to operate, so that the two arc-shaped pressure plates 172 on the same U-shaped plate 17 approach each other, and squeezes water out of the roll of absorbent cloth 902 wound on the winding rod 901 to ensure the water absorption performance of the absorbent cloth 902. Then, the winding motor is controlled to reverse to enable the absorbent cloth 902 to absorb the moisture on the ketone body again. There is no need to manually stop the machine to disassemble and replace the roll of absorbent cloth 902, which reduces the workload of the staff and enables the ketone body detection of beef cattle to be carried out continuously, thereby improving the ketone body detection efficiency of beef cattle. It should be noted that a water collection trough or drainage hole should be provided on the side of the light shield 3 on the conveyor belt 202 to facilitate the treatment of the water discharged by the absorbent cloth 902.

[0056] like Figure 1 and Figure 2 As shown, as a preferred embodiment, on the basis of the above method, the flushing mechanism further includes a mounting frame 16 fixed on the frame 1, a drain pipe 161 arranged on the mounting frame 16, a nozzle 162 equidistantly and obliquely arranged on the drain pipe 161, and a water pipe 163 connected to the drain pipe 161, and the end of the water pipe 163 away from the drain pipe 161 is connected to a water supply device; the water supply device is a prior art and will not be described in detail here. The water supply device inputs water into the drain pipe 161 through the water pipe 163, and the nozzle 162 on the drain pipe 161 sprays water at an inclined angle to flush the minced meat and impurities on the surface of the beef carcass. The flushed minced meat and impurities fall from the front end of the belt conveyor 2 to avoid entering the light shield 3 with the conveyor belt 202.

[0057] The present invention also discloses a method for non-destructive grading and detection of beef cattle carcasses using multi-spectral infrared imaging, which is performed by using a non-destructive grading and detection device for beef cattle carcasses using multi-spectral infrared imaging, and further includes the following steps:

[0058] S1: The beef cattle carcass to be inspected is placed on the conveyor belt 202, and the belt conveyor 2 and the water supply device are started. The beef cattle carcass moves along the conveyor belt 202 toward the inspection area within the light shield 3. During this process, the nozzle 162 of the flushing mechanism sprays water at an inclined angle to flush away the minced meat and impurities on the surface of the beef cattle carcass;

[0059] S2: After the beef cattle carcass enters the light shield 3, it first presses against the second inclined surface of the guide plate 9. The guide plate 9 is forced upward, the second telescopic rod 8 contracts, and the winding motor drives the winding rods 901 to rotate. One winding rod 901 releases the absorbent cloth 902, while the other winding rod 901 rewinds the absorbent cloth 902. This drives the absorbent cloth 902 to dynamically absorb the water droplets remaining on the beef cattle carcass. The tensioning rod 151 maintains a constant tension on the absorbent cloth 902 through the elastic telescopic plate 15.

[0060] S3: When the reeling rod 901 rotates, the crank shaft 11 is driven to rotate via the second synchronous wheel 12 and the second synchronous belt. When the crank shaft 11 rotates, the lifting rod 14 is driven to move back and forth up and down via the swing rod 13. When the lifting rod 14 moves, it drives the elastic telescopic rod 141 and the pressing rod 142 to move up and down, so that the pressing rod 142 presses the absorbent cloth 902 downward, so that the absorbent cloth 902 can be in close contact with the surface of the beef cattle, so that the absorbent cloth 902 can fully absorb the moisture on the surface of the beef cattle;

[0061] S4: After the water droplets are removed, the carcass of the beef cattle moves to the guide frame 603. The first inclined surface of the guide frame 603 is forced upward, causing the detection integration 5 on the guide frame 603 to automatically adjust its height to adapt to the height difference of the beef cattle carcass surface. The incident light source is split by the filter and illuminates the carcass. The diffuse reflection optical fiber collects the reflected spectrum signal. The spectrometer 4 collects data at a frequency of 10 times per second.

[0062] S5: When the belt conveyor 2 is working, one of the conveying rollers 201 drives the reciprocating screw 6 to rotate through the first synchronous wheel 7 and the first synchronous belt, and the sleeve 601 drives the guide frame 603 to reciprocate along the axial direction of the reciprocating screw 6 through the first telescopic rod 602, so that the detection integration 5 can detect different positions of the same beef cattle carcass. After detection, the beef cattle carcass is moved out from the outlet of the light shield 3 and enters the next processing step.

10. A method for non-destructive grading and testing of beef cattle carcasses using multi-spectral infrared imaging, comprising: performing testing using the non-destructive grading and testing device for beef cattle carcasses using multi-spectral infrared imaging according to claim 9, wherein: The following steps are also included: S1: placing a beef cattle carcass to be inspected on a conveyor belt (202), starting the belt conveyor (2) and the water supply equipment, and the beef cattle carcass moves along the conveyor belt (202) toward the inspection area within the light shield (3). During this process, the nozzle (162) of the flushing mechanism sprays water at an inclined angle to flush away the minced meat and impurities on the surface of the beef cattle carcass; S2: After the beef cattle carcass enters the interior of the light shield (3), it will first squeeze the second inclined surface of the guide plate (9), the guide plate (9) is forced to move upward, the second telescopic rod (8) contracts, and the reeling motor drives the reeling rod (901) to rotate, one reeling rod (901) releases the absorbent cloth (902), and the other reeling rod (901) reels the absorbent cloth (902), driving the absorbent cloth (902) to dynamically absorb the water droplets remaining on the beef cattle carcass, and the tensioning rod (151) keeps the tension of the absorbent cloth (902) constant through the elastic telescopic plate (15); S3: When the reeling rod (901) rotates, the crank shaft (11) is driven to rotate through the second synchronous wheel (12) and the second synchronous belt. When the crank shaft (11) rotates, the lifting rod (14) is driven to move up and down through the swing rod (13). When the lifting rod (14) moves, the elastic telescopic rod (141) and the pressure rod (142) are driven to move up and down, so that the pressure rod (142) presses the absorbent cloth (902) downward, and the absorbent cloth (902) can be in close contact with the surface of the beef cattle, so that the absorbent cloth (902) can fully absorb the moisture on the surface of the beef cattle; S4: After the water droplets are removed, the carcass of the beef cattle moves to the guide frame (603). The first inclined surface of the guide frame (603) is forced to move upward, so that the detection integration (5) on the guide frame (603) automatically adjusts its height to adapt to the height difference of the beef cattle carcass surface. The incident light source is split by the filter and then illuminates the carcass. The diffuse reflection optical fiber collects the reflected spectrum signal. The spectrometer (4) collects data at a frequency of 10 times per second. S5: When the belt conveyor (2) is working, one of the conveying rollers (201) drives the reciprocating screw (6) to rotate through the first synchronous wheel (7) and the first synchronous belt, and the sleeve (601) drives the guide frame (603) to move back and forth along the axial direction of the reciprocating screw (6) through the first telescopic rod (602), so that the detection integration (5) can detect different positions of the same beef cattle carcass. After the detection, the beef cattle carcass is removed from the outlet of the light shield (3) and enters the next processing step.
