Description

Technical Field

[0001] The invention belongs to the technical field of food detection, and in particular relates to food non-destructive detection equipment based on optical detection. Background Art

[0002] The food processing industry packages processed food for the purpose of preserving and selling it, including meat products such as pork. Packaged food needs to undergo strict testing to eliminate products with poor packaging problems. The testing process generally involves aspects such as packaging printing quality, sealing performance and weight. Efficient and convenient food packaging testing equipment can monitor various defects and damage problems that occur during food packaging, thereby ensuring that food maintains good preservation effects and food safety during transportation and storage, and completely eliminating the occurrence of unqualified products.

[0003] In the Chinese patent with publication number CN217981232U, a rapid testing device for food testing is mentioned. The rotating placement structure adopted in this case can rotate and place the samples to be tested. The staff only needs to place the samples one by one on the upper end of the rotating disk. The servo motor can drive the samples to rotate step by step. The downward pressure detection structure is set to collect and test the samples multiple times, and the unloading rod is set to automatically unload the samples after the test is completed, which reduces the participation steps of the staff, increases the detection efficiency of the samples, and ensures the detection effect of the samples; However, when using the device for food testing, its detection range is relatively limited. This limitation makes it difficult for the device to comprehensively and deeply evaluate the internal and external characteristics of the food. Whether it is the internal structure, ingredient distribution, or external morphology and surface characteristics of the food, they may not be fully revealed and evaluated due to the limitation of the detection range. This not only affects our accurate judgment of the overall quality of the food, but also increases the difficulty and uncertainty of food safety assessment. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0019] See also Figures 1 to 8 As shown, the food non-destructive testing equipment based on optical detection includes: Detection rack 1; Two detection racks 1 are provided, and a detection mechanism 2 is installed at the top of each of the two detection racks 1, and a flip mechanism 3 is installed between the opposite surfaces of the two detection racks 1, a rotating mechanism 4 is installed at the middle of the top of the flip mechanism 3, and a control panel 5 is installed at the middle of the outer wall of the flip mechanism 3; The detection mechanism 2 includes an X-ray machine 21, a support frame 22, a near-infrared spectrometer 23, a probe connecting line 24, a spectrometer probe 25 and a visible light camera 26. The X-ray machine 21 is installed at the top of the detection frame 1, the support frame 22 is installed at one end of the X-ray machine 21, the near-infrared spectrometer 23 is installed at the top of the support frame 22, and three probe connecting lines 24, spectrometer probes 25 and visible light cameras 26 are each provided. The three probe connecting lines 24 are all installed at the other end of the near-infrared spectrometer 23, and the three spectrometer probes 25 are respectively installed at the other ends of the three probe connecting lines 24, and the three spectrometer probes 25 are respectively installed on one side of the three inner walls of the support frame 22, and the three visible light cameras 26 are respectively installed on the other side of the three inner walls of the support frame 22.

[0020] Depend on Figures 1 to 4 It can be seen that a supporting base frame 6 is installed at the bottom end of the two detection racks 1, a conveyor belt 7 is installed between the inner walls on both sides of the two detection racks 1, a waste box 8 is installed on one side of the outer wall of the two detection racks 1, and a feed port 9 is opened on the upper part of the outer wall of the two waste boxes 8, and a motor 10 is installed on the other side of the outer wall of the two detection racks 1; A display screen 27 is installed in the middle of the outer wall of the X-ray machine 21, a support plate 28 is installed at the lower part of one end of the X-ray machine 21, an electric push rod 29 is installed in the middle of the outer wall of the support plate 28, and the output end of the electric push rod 29 passes through the outer wall of the support plate 28 and is installed with a push plate 210.

[0021] As can be seen from the above, when the food to be inspected is transmitted to the inspection mechanism 2 on the left side through the conveyor belt 7, first, the surface features of the three sides of the food can be observed through the three visible light cameras 26 to quickly identify defects and contamination. Subsequently, the three spectrometer probes 25 connected to the near-infrared spectrometer 23 can be used to analyze the chemical composition and temperature distribution of the food, so as to judge its freshness and maturity. Then, the food enters the X-ray machine 21 for perspective inspection. The perspective function of the X-ray machine 21 can penetrate the surface of the food, which is particularly critical for foreign body detection. These technologies jointly use optical principles to perform non-contact inspection of food, avoiding physical damage or contamination to the food while maintaining the integrity of the food. The comprehensive application of these technologies realizes the accurate identification of tiny defects and foreign bodies in food, as well as the comprehensive and efficient evaluation of the internal and external characteristics of food. When inspecting pork, the visible light camera 26 is used to capture the appearance image of pork. Observe its color, texture and other macroscopic features. The near-infrared spectrometer 23 cooperates with the spectrometer probe 25 to determine the content of chemical components such as water, fat, and protein in pork. The X-ray machine 21 can be used to check whether there are foreign objects or structural abnormalities in pork. In this way, multi-dimensional detection of pork can be achieved. In addition, the setting of the two detection mechanisms 2 makes the detection range of the detection device wider, so that the overall quality of the food can be judged more accurately. In this way, the quality, composition and safety of the food can be evaluated more accurately. The three detection devices can transmit the detection data to the display screen 27 for display. When it is identified that the food packaging is damaged or there are foreign objects inside the food, the conveyor belt 7 first transports the food to the vicinity of the push plate 210, and then the control panel 5 controls the electric push rod 29 to start, and the electric push rod 29 extends to push the push plate 210 to push the food, so that the food enters the waste box 8 through the feed port 9 to achieve offline processing of defective products.

[0022] Specifically, refer to Figures 1 to 4 As shown, the electric push rod 29, the display screen 27, the near-infrared spectrometer 23, the X-ray machine 21 and the motor 10 are all electrically connected to the control panel 5, the bottom end surface of the push plate 210 is higher than the top end surface of the conveyor belt 7, and the bottom wall of the feed port 9 is flush with the top end surface of the conveyor belt 7.

[0023] As can be seen from the above, it is ensured that these devices can be operated and controlled through the control panel 5 to realize the automation and intelligent management of the equipment, ensure that the pushing plate 210 does not produce unnecessary friction or interference with the conveyor belt 7 when pushing food, and at the same time ensure that the food can be pushed to the specified position smoothly, ensure that the food can smoothly pass through the feed port 9 from the conveyor belt 7 and fall into the waste box 8, and avoid food jamming during the pushing process. Example

[0024] refer to Figures 5 to 7As shown, the flip mechanism 3 includes a fixed frame 31, a limiting frame 32, a flip frame 33, a flip plate 34 and a storage slot 35. The fixed frame 31 is installed between the opposite surfaces of the two detection frames 1. Two limiting frames 32 are provided, and the two limiting frames 32 are respectively installed on the inner walls of both sides of the fixed frame 31. The flip frame 33 is installed between the inner walls of both sides of the fixed frame 31. The flip plate 34 is installed in the middle of the outer surface of the flip frame 33. The storage slot 35 is opened at the top of the flip plate 34. The flip frame 33 includes a flip shaft 331, a driver 332 and a limit rod 333. The flip shaft 331 is installed between the inner walls on both sides of the fixed frame 31 through a bearing. The driver 332 is installed at one end of the flip shaft 331. Two limit rods 333 are provided, and the two limit rods 333 are respectively installed on both sides of the outer surface of the flip shaft 331.

[0025] As can be seen from the above, when the food that has passed the initial inspection is transferred to the flip plate 34, the operator can control the start of the rotating mechanism 4 and the driver 332 in sequence through the control panel 5. The rotating mechanism 4 first works to clamp the food and rotate it. Then, the driver 332 starts to drive the flip shaft 331 to rotate, thereby causing the flip plate 34 and the food fixed on the rotating disk 41 to flip significantly. In this process, the limit rod 333 slides on the limit frame 32, which plays a role in stabilizing the flipping action and limiting the flipping range. When the food is flipped to the predetermined position, the control panel 5 issues an instruction again to control the rotating mechanism 4 to cancel the clamping of the food. At this time, the food is stably flipped and placed on the conveyor belt 7 on the right, thereby realizing the re-inspection of the bottom and side of the food. This design not only significantly enhances the detection effect, improves the accuracy and comprehensiveness of the detection, but also speeds up the detection speed through automated processes, thereby perfectly meeting the needs of large-scale production lines for efficient detection.

[0026] Preferably, reference Figures 5 to 7 As shown, the driver 332 is electrically connected to the control panel 5, the limit rod 333 is slidably connected to the limit frame 32, and the limit rod 333 is set to an L-shaped structure, the limit frame 32 is set to an arc structure, the top surface of the flip plate 34 is flush with the top surface of the conveyor belt 7, and one end surface of the flip plate 34 is set to an arc structure.

[0027] As can be seen from the above, it is ensured that the driver 332 can receive the instructions of the control panel 5 and drive the relevant mechanical parts to move. The movement range of the relevant mechanical parts is limited by the sliding of the limit rod 333 on the limit frame 32, ensuring that the mechanical parts move within the predetermined track. The L-shaped limit rod 333 provides additional stability and support force. The arc-shaped limit frame 32 can better adapt to the specific mechanical movement trajectory and provide a smooth sliding path for the limit rod 333, ensuring that the food on the conveyor belt 7 can be smoothly moved to the flip plate 34. The end face of the arc structure prevents the flip plate 34 from contacting the conveyor belt 7, which is also conducive to the smooth transmission of food. Example

[0028] refer to Figure 8 As shown, the rotating mechanism 4 includes a rotating disk 41, a driving motor 42, a fixed block 43, an electric telescopic rod 44 and a fixed splint 45. The rotating disk 41 is mounted on the bottom inner wall of the storage groove 35 through a bearing, the driving motor 42 is mounted in the middle of the bottom end of the rotating disk 41, and two fixed blocks 43, electric telescopic rods 44 and fixed splints 45 are provided. The two fixed blocks 43 are respectively mounted on both sides of the top of the rotating disk 41, and the two electric telescopic rods 44 are respectively mounted on the opposite sides of the two fixed blocks 43. The two fixed splints 45 are respectively mounted on the output ends of the two electric telescopic rods 44.

[0029] As can be seen from the above, when the food is successfully transported to the rotating disk 41 in the flip plate 34 through the conveyor belt 7 on the left, the staff can easily control the start of the electric telescopic rod 44 through the control panel 5. As the electric telescopic rod 44 extends, it will push the fixed clamping plate 45 to move to the middle until the two fixed clamping plates 45 are tightly matched to clamp the food on the rotating disk 41. Then, through the control panel 5 again, the operator can control the start of the drive motor 42. The drive motor 42 starts to drive the rotating disk 41 to rotate, thereby rotating the food on the rotating disk 41 by ninety degrees, and flipping the food through the flipping mechanism 3 to transport it to the conveyor belt 7 on the right. This design cleverly enables the detection mechanism 2 on the right to re-detect the food, especially for the other two sides of the food, which greatly improves the flexibility and coverage of the detection. Through such a design, it is not only conducive to comprehensive detection of all sides of the food, but also can effectively improve the accuracy and reliability of the detection, thereby further improving the comprehensiveness and quality of food detection.

[0030] Preferably, reference Figure 8 As shown, the top end surface of the rotating disk 41 is flush with the top end surface of the flip plate 34 , the driving motor 42 and the electric telescopic rod 44 are both electrically connected to the control panel 5 , and the bottom end surface of the fixing clamp 45 is in contact with the top end surface of the rotating disk 41 .

[0031] As can be seen from the above, to ensure that the food on the flip plate 34 can be smoothly moved to the rotating disk 41 for rotation adjustment, the contact between the fixed clamping plate 45 and the rotating disk 41 can limit the fixed clamping plate 45 and improve the stability of the fixed clamping plate 45.

[0032] Application examples: This design is widely used in many key links such as food processing, quality control, logistics warehousing and retail, especially in the following specific scenarios, it shows its indispensable importance and significant advantages: on food processing production lines (such as meat, fruit and vegetable, dairy products, etc.), the equipment can quickly and non-contactly detect multiple quality indicators of products, including but not limited to freshness, maturity, foreign matter (such as metal fragments, plastic pieces, etc.), moisture content and fat content, so as to ensure that the products strictly meet safety and quality standards, effectively reduce the defective rate, and greatly improve production efficiency; The essence of this design is to cleverly integrate different optical bands (visible light, infrared, X-ray) for non-destructive testing. Specifically: visible light is mainly used to directly observe the surface morphology, color changes and other characteristics of food, which helps to quickly identify surface defects, contamination or maturity. Infrared spectroscopy technology accurately measures the absorption or reflection characteristics of food to infrared light of different wavelengths, and deeply analyzes the key chemical components of food such as moisture content, sugar, protein, and temperature distribution, which is crucial for accurately judging the freshness and maturity of food. X-ray perspective detection can penetrate the surface of food and intuitively display the internal structure, such as bones, foreign matter, bubbles, etc., which is particularly critical for foreign matter detection in meat, fruits and vegetables; In the above application scenario, the design uses a variety of optical detection technologies in combination, and the detection mechanism 2 realizes a comprehensive and in-depth evaluation of food from appearance to internal structure, from chemical composition to physical properties, significantly improving the detection efficiency and accuracy. It can not only quickly identify unqualified products, effectively reduce the subjectivity and misjudgment rate of manual inspection, but also complete the detection task without damaging the food itself, avoiding the waste of resources that may be caused by traditional destructive detection methods. Specifically, the detection mechanism 2 combines the visible light camera 26, the near-infrared spectrometer 23, the spectrometer probe 25 and the X-ray machine 21 to realize multi-dimensional detection of pork. Among them, the visible light camera 26 is used to observe the appearance characteristics of pork, the near-infrared spectrometer 23 cooperates with the spectrometer probe 25 to determine the chemical composition of pork, which is particularly helpful for detecting key nutritional indicators such as n-3 PUFA (polyunsaturated fatty acids), and the X-ray machine 21 is used to check the structural abnormalities and foreign matter of pork. In addition, the design of the flip mechanism 3 and the rotating mechanism 4 ensures that all sides of the food can be evenly and carefully detected, further enhancing the comprehensiveness and reliability of the detection, and providing solid and powerful technical support for food safety and quality control.
