Description

Technical Field

[0001] The present invention relates to the technical field of optical detection equipment, and specifically relates to an optical detection device for ham food safety. Background Art

[0002] As a traditional meat product deeply loved by consumers, optical detection technology has the advantages of non-contact, rapidity, non-destruction, etc. in the field of food detection. It can effectively detect various quality and safety indicators in ham, such as impurities, color, microbial contamination, etc., to ensure the quality of ham and the health of consumers.

[0003] During the processing of ham food, in order to avoid the presence of microorganisms on the surface of ham food affecting other ham foods, since existing disinfection means will affect the components of food, it is necessary to conduct optical detection on a large number of ham foods, so as to ensure the health and safety of ham food and reduce the damage of microorganisms to ham food. Ham food is usually irradiated by infrared light emitted by a near-infrared spectrometer onto the surface of the ham. The light interacts with the molecules in the ham. Part of the light is absorbed, and the rest of the light is reflected back. The detector of the spectrometer receives the reflected light and converts it into an electrical signal, recording the absorbance at different wavelengths, thereby obtaining the near-infrared absorption spectrum of the ham. Whether the ham is infected by microorganisms can be known through the near-infrared absorption spectrum.

[0004] In order to conduct comprehensive detection, existing optical detection devices usually perform optical detection on the back of the object to be detected, thus ensuring the comprehensiveness of the detection. The existing optical detection device for ham food safety needs to perform optical detection on both sides of the ham food in two separate operations. The Chinese invention discloses an intelligent optical detection device and an optical detection method with the application number CN202111636068.5. By setting a first driving device and a second driving device, the camera can be driven to move within a plane, enabling the taking of pictures at various positions of the workpiece. Then, the picture data is transmitted to the terminal, and the optical detection of the workpiece is completed by observing and detecting the pictures. The detection efficiency is high, the speed is fast, and it is more comprehensive. By setting a clamping device, the workpiece can be clamped and rotated, enabling the workpiece to be turned over, making the detection more convenient, providing a solution for detecting two sides or even multiple sides. However, ham food is generally flat in shape and varies in size. Compared with the regular shape of the workpiece, the operability of clamping and turning over ham food is relatively low, and the operation efficiency is slow, lacking feasibility in the detection of a large number of ham foods. Moreover, due to some areas of ham food being curved surfaces, the existing optical detection device cannot display the entire surface of the ham food on the detection surface of the optical detection device, and it is very easy to miss the detection of some areas of the ham food during the detection process, resulting in the spread of microorganisms in the ham food, thereby reducing the detection accuracy of the optical detection device for ham food safety. Therefore, an optical detection device for ham food safety is designed. Summary of the Invention

The three groups of first ultraviolet germicidal lamps 16 disinfect the conveying areas on the conveyor belt 1, the detection belt 11, and the sorting belt 12 respectively, and do not disinfect the ham food, ensuring the nutritional components of the ham food. On the surface of the detection belt 11, there is a detection mechanism. The detection mechanism includes a support frame 2. There are two groups of support frames 2. One group of support frames 2 is fixedly connected to the surface of the detection belt 11, and the other group of support frames 2 is slidably connected to the surface of the detection belt 11. On the surface of the support frame 2, there is a first motor 21 fixedly connected. On the output shaft of the first motor 21, there is a first lead screw 22 fixedly connected. On the surface of the first lead screw 22, there is a lifting block 23 threadedly connected. On the surface of the lifting block 23, there is a first cylinder 24 fixedly connected.

On the surface of the turntable 26, there is a turntable 26. On the surface of the turntable 26, there is a guide rod 28 slidably connected. On the surface of the guide rod 28, there is a pressing plate 29 fixedly connected. On the surface of the turntable 26, there is a fixing nut 210 fixedly connected. On the surface of the fixing nut 210, there is a limiting screw 211 threadedly connected. On the surface of the support frame 2, there is a telescopic plate 3 fixedly connected. The telescopic plate 3 is fixedly connected to the surface of the support frame 2. At the bottom of the telescopic plate 3, there is an infrared spectrum emitter 31 fixedly installed. At the bottom of the telescopic plate 3, there is an infrared spectrum receiver 32 fixedly installed. On the surface of the telescopic plate 3, there is a second cylinder 33 fixedly connected. The piston end of the second cylinder 33 is fixedly connected to a connecting plate 34. The connecting plate 34 is fixedly connected to the telescopic end of the telescopic plate 3. On one side of the support frame 2, there is a second motor 35 fixedly connected. On the output shaft of the second motor 35, there is a second lead screw 36 fixedly connected. The second lead screw 36 is rotatably connected to the bottom of the telescopic plate 3. On the surface of the second lead screw 36, there is a connecting bracket 37 threadedly connected. At the bottom of the connecting bracket 37, there is a second ultraviolet germicidal lamp 38 fixedly installed. On one side of the support frame 2, there is a support rod 4 fixedly connected. At the bottom of the support rod 4, there is a third cylinder 41 rotatably connected. At the bottom of the support frame 2, there is a fourth cylinder 42 rotatably connected. The piston rod of the infrared spectrum emitter 31 is rotatably connected to the surface of the fourth cylinder 42.A limit block 43 is fixedly connected to the piston rod of the fourth cylinder 42, a fifth cylinder 44 is rotatably connected to the surface of the detection belt conveyor 11, an extrusion rod 45 is rotatably connected to the piston rod of the fifth cylinder 44, a connecting cross bar 46 is fixedly connected to the surface of the fifth cylinder 44, a sixth cylinder 47 is rotatably connected to the surface of the detection belt conveyor 11, a connecting ring 48 is fixedly connected to the piston rod of the sixth cylinder 47, and the connecting ring 48 is movably connected to the surface of the connecting cross bar 46. The detection mechanism performs optical detection of microorganisms on the surface of the ham food on the detection belt conveyor 11, and the detection mechanism can quickly adjust the angle of the ham food without using a clamping scheme, and then perform optical detection of the ham food, thereby ensuring the efficiency of the optical detection of the ham food and avoiding the phenomenon of missing the optical detection of the ham food, thereby avoiding the phenomenon of microorganisms spreading in the ham food, and improving the detection accuracy of the ham food safety optical detection device.

[0034] Furthermore, guide holes are provided on both sides of the support frame 2. The first motor 21 drives the first screw rod 22 to rotate on the guide hole of the support frame 2 through the output shaft. The first screw rod 22 drives the lifting block 23 to slide and lift on the guide hole of the support frame 2 through rotation. The lifting block 23 is in an "h" shape as a whole. The lifting block 23 drives the first cylinder 24 and the polyvinyl chloride sheet 27 to rise and fall synchronously on the surface of the support frame 2. The lifting block 23 is provided with four groups. The height of the polyvinyl chloride sheet 27 can be lowered at the same time by four groups of lifting blocks 23. The processable polyvinyl chloride sheet 27 can be lowered to the surface of the detection belt conveyor 11. At this time, the conveyor belt of the detection belt conveyor 11 can transfer the ham food to the surface of the polyvinyl chloride sheet 27, so as to facilitate the polyvinyl chloride sheet 27 to adjust the angle of the ham food. The four groups of lifting blocks 23 are lifted and lowered separately, and the angle of the polyvinyl chloride sheet 27 can be adjusted, thereby adjusting the angle of the ham food.

[0035] Furthermore, four groups of first cylinders 24 are provided, and are respectively provided on two groups of support frames 2. The first cylinder 24 drives the connecting disc 25 and the turntable 26 to move horizontally on the support frame 2 through the piston rod. During the movement, the turntable 26 drives the polyvinyl chloride sheet 27 to deform directly above the detection belt conveyor 11. Four groups of turntables 26 are provided. The polyvinyl chloride sheet 27 rotates on the connecting disc 25 through four groups of turntables 26, so as to facilitate the adjustment of the angle of the first screw rod 22. During the movement, the turntable 26 changes the curvature of the polyvinyl chloride sheet 27 itself. The curvature of the polyvinyl chloride sheet 27, combined with the change in the height of both sides of the polyvinyl chloride sheet 27 and the inclination of the angle of the polyvinyl chloride sheet 27, can flip the ham food on the polyvinyl chloride sheet 27, and can display various angles of the ham food to the infrared spectrum emitter 31 at the bottom of the telescopic plate 3.

[0036] Furthermore, a card slot is provided on the surface of the turntable 26, and a guide groove and a circular hole are provided above the card slot of the turntable 26. The guide rod 28 slides on the guide groove of the turntable 26, and the pressing plate 29 slides on the card slot of the turntable 26 through the guide rod 28. The limit screw rod 211 passes through the circular hole of the turntable 26 through the fixing nut 210, and the limit screw rod 211 presses and limits the polyvinyl chloride sheet 27 on the card slot of the turntable 26 through the pressing plate 29. The fixing nut 210 restricts one end of the polyvinyl chloride sheet 27 on the card slot of the turntable 26, thereby realizing the limit of one side of the polyvinyl chloride sheet 27. The polyvinyl chloride sheet 27 can be disassembled on the card slot of the turntable 26, thus facilitating the replacement task of the polyvinyl chloride sheet 27 on the turntable 26.

[0037] Furthermore, the telescopic end of the telescopic plate 3 is fixedly connected to a set of movable support frames 2. The second air cylinder 33 drives the connecting plate 34 to move through the piston rod. The connecting plate 34 drives the support frame 2 to slide on the surface of the inspection belt conveyor 11 through the piston end of the telescopic plate 3. During the process of the angular rotation of the polyvinyl chloride sheet 27, since the polyvinyl chloride sheet 27 rotates on the connecting disc 25 through the turntable 26, it is necessary to adjust the positions of the two sets of support frames 2, so as to ensure that the rotated polyvinyl chloride sheet 27 can still rotate on the connecting disc 25 through the turntable 26. It is necessary to adjust the distance between the two sets of support frames 2. The connecting plate 34 cooperates with the second air cylinder 33 to move one set of support frames 2, thereby changing the positions between the two sets of support frames 2. The positions of the infrared spectrum emitter 31 and the infrared spectrum receiver 32 at the bottom of the telescopic plate 3 remain unchanged, and the infrared spectrum emitter 31 and the infrared spectrum receiver 32 at the bottom of the telescopic plate 3 cooperate to perform optical detection on the ham food on the polyvinyl chloride sheet 27. The infrared spectrum emitter 31 and the infrared spectrum receiver 32 are prior art. The light emitted by the infrared spectrum emitter 31 interacts with the molecules in the ham, part of the light is absorbed, and the rest of the light is reflected back. The infrared spectrum receiver 32 receives the reflected light and converts it into an electrical signal.

[0038] Further, the second motor 35 drives the second lead screw 36 to rotate at the bottom of the telescopic plate 3 through an output shaft. The second lead screw 36 drives the connecting bracket 37 to slide at the bottom of the telescopic plate 3 through rotation. The connecting bracket 37 is misaligned with the infrared spectrum emitter 31 and the infrared spectrum receiver 32. The connecting bracket 37 is in an overall "L" shape. The connecting bracket 37 drives the second ultraviolet germicidal lamp 38 to slide at the bottom of the telescopic plate 3. The second ultraviolet germicidal lamp 38 disinfects and sterilizes the ham food on the polyvinyl chloride sheet 27. The second ultraviolet germicidal lamp 38 can disinfect and sterilize the entire polyvinyl chloride sheet 27 by moving. Before the polyvinyl chloride sheet 27 is disinfected and sterilized, the polyvinyl chloride sheet 27 needs to be pulled into a flat surface and moved to the bottom of the second ultraviolet germicidal lamp 38 to ensure the disinfection and sterilization effect.

[0039] Further, the fourth cylinder 42 drives the limit block 43 to move up and down through a piston rod. The third cylinder 41 drives the fourth cylinder 42 to rotate at the bottom of the support frame 2 through a piston rod. The fourth cylinder 42 drives the limit block 43 to rotate synchronously on the support frame 2. There are two groups of limit blocks 43. The limit block 43 moves to one side of the polyvinyl chloride sheet 27 through rotation for limiting. In the case where the polyvinyl chloride sheet 27 is inclined at an angle, in order to prevent the ham food on the polyvinyl chloride sheet 27 from falling off, the limit block 43 can support the polyvinyl chloride sheet 27 on one side, so as to ensure that the ham food at different angles on the polyvinyl chloride sheet 27 can continue to be optically detected.

[0040] Further, the fifth cylinder 44 drives the extrusion rod 45 to move through a piston rod. The extrusion rod 45 moves to the bottom of the polyvinyl chloride sheet 27 through the piston rod of the fifth cylinder 44. The extrusion rod 45 pushes the polyvinyl chloride sheet 27 to deform during the moving process. The length of the extrusion rod 45 is the same as the length of the polyvinyl chloride sheet 27. And there are two groups of fifth cylinders 44 rotated on each group. The two ends of the connecting cross bar 46 are fixedly connected to the surface of the fifth cylinder 44. Since the ham food is flat, it is easy to appear unstable during the process of turning over the ham food. The extrusion rod 45 can be at the bottom of the polyvinyl chloride sheet 27 and deform the polyvinyl chloride sheet 27 by pushing, so as to limit the position of any turning angle of the ham food on the polyvinyl chloride sheet 27, which is convenient for optically detecting different sides of the ham food on the polyvinyl chloride sheet 27.

[0041] Further, the sixth cylinder 47 drives the connecting ring 48 to move through the piston rod. During the movement of the connecting ring 48, the connecting cross bar 46 rotates on the connecting ring 48, and the sixth cylinder 47 itself rotates on the detection belt conveyor 11. During the rotation of the sixth cylinder 47, the fifth cylinder 44 is driven to rotate through the connecting cross bar 46 and the connecting ring 48. During the rotation of the fifth cylinder 44, the pushing position of the extrusion rod 45 at the bottom of the polyvinyl chloride sheet 27 is changed. By changing the pushing position of the extrusion rod 45, the turning angle of the ham food on the polyvinyl chloride sheet 27 can be limited in more directions, and the extrusion rod 45 can limit different ham foods, improving the adaptability of the extrusion rod 45 to push.

[0042] Further, there are three groups of the first ultraviolet germicidal lamps 16, and the first ultraviolet germicidal lamps 16 on the detection belt conveyor 11 are arranged below. The first ultraviolet germicidal lamps 16 disinfect the conveying areas of the conveying belt conveyor 1, the detection belt conveyor 11 and the sorting belt conveyor 12 respectively, avoiding cross-infection of microorganisms of ham food. The feeding device 14 pushes the unqualified ham food on the sorting belt conveyor 12 onto the material cylinder 15. The infrared spectrum receiver 32 inputs the electrical signal to the computer console 17. The computer console 17 calculates the electrical signal input by the infrared spectrum receiver 32, and the computer console 17 controls the entire detection mechanism on the detection belt conveyor 11. The computer console 17 will detect the ham food with excessive microorganisms and push the unqualified ham food to the material cylinder 15 through the feeding device 14 for unified treatment.

[0043] Working principle: The output shaft of the first motor 21 drives the first lead screw 22 to rotate. During the rotation process, the lifting block 23 is driven to slide on the support frame 2. The lifting block 23 drives the polyvinyl chloride sheet 27 to descend through the first cylinder 24, so that the polyvinyl chloride sheet 27 descends to the surface of the detection conveyor belt 11. The detection conveyor belt 11 conveys the ham food to the surface of the polyvinyl chloride sheet 27, and the polyvinyl chloride sheet 27 then lifts the ham food. At this time, the four groups of lifting blocks 23 can respectively lift the four directions of the polyvinyl chloride sheet 27, and the angle of the polyvinyl chloride sheet 27 on the support frame 2 can be changed. At the same time, the four groups of first cylinders 24 can also change the bending rate of the polyvinyl chloride sheet 27 through the piston rods from four positions. Through the bending of the polyvinyl chloride sheet 27 and the inclination of the angle of the polyvinyl chloride sheet 27, the polyvinyl chloride sheet 27 can drive the ham food to turn over at multiple angles, so that the infrared spectrum emitter 31 and the infrared spectrum receiver 32 perform optical detection on the ham food at multiple angles. And all sides of the ham food can be shown to the infrared spectrum emitter 31 and the infrared spectrum receiver 32 for optical detection by the polyvinyl chloride sheet 27, avoiding omissions in optical detection. At the same time, the fifth cylinder 44 pushes the driving second motor 35 at the bottom of both sides of the polyvinyl chloride sheet 27 through the piston rod. At the same time, the sixth cylinder 47 changes the angle of the fifth cylinder 44 through the piston rod and the sixth cylinder 47 sliding into the connecting ring 48, so as to cover the position where the extrusion rod 45 pushes at the bottom of the polyvinyl chloride sheet 27. With the cooperation of the extrusion rod 45 pushing, the stability of the position after the polyvinyl chloride sheet 27 is pushed up and flipped can be guaranteed, and then the stability of the optical detection of the ham food is guaranteed. And the third cylinder 41 drives the fourth cylinder 42 to rotate at the bottom of the support frame 2 through the piston rod. The fourth cylinder 42 drives the limit block 43 to rotate synchronously on the support frame 2. The limit block 43 can rotate to one end of the polyvinyl chloride sheet 27 to limit the ham food on the polyvinyl chloride sheet 27, avoiding the phenomenon that the ham food on the polyvinyl chloride sheet 27 falls. Without using the clamping scheme, the angle of the ham food is quickly adjusted, and then the optical detection of the ham food is carried out. While ensuring the optical detection efficiency of the ham food, the phenomenon of omission in the optical detection of the ham food is avoided, and then the phenomenon of microbial diffusion in the ham food is avoided, improving the detection accuracy of the optical detection device for ham food safety.

Rotate the limit screw 211 on the surface of the fixing nut 210 so that the limit screw 211 passes through the circular hole of the turntable 26. Squeeze the pressing plate 29 on the card slot of the turntable 26. Under the guidance of the two groups of guide rods 28, the pressing plate 29 vertically presses the polyvinyl chloride sheet 27 on the card slot of the turntable 26, so as to realize the limit of the polyvinyl chloride sheet 27 on the card slot of the turntable 26, which is convenient for the installation and disassembly of the polyvinyl chloride sheet 27 on the turntable 26.

[0045] The output shaft of the second motor 35 drives the second lead screw 36 to rotate at the bottom of the telescopic plate 3. The second lead screw 36 drives the connecting bracket 37 to slide at the bottom of the telescopic plate 3 through rotation. During the sliding process, the connecting bracket 37 drives the second ultraviolet germicidal lamp 38 to move. The second ultraviolet germicidal lamp 38 can comprehensively disinfect the entire surface of the polyvinyl chloride sheet 27 during the movement. Moreover, the first ultraviolet germicidal lamp 16 can also disinfect the conveying areas of the conveyor belt 1, the inspection belt 11, and the sorting belt 12, avoiding cross-infection of microorganisms on the ham food by the optical detection device.
