Description

Technical Field

[0001] This invention belongs to the field of food processing quality inspection technology, and specifically discloses a food processing defect detection device based on artificial intelligence recognition. Background Technology

[0002] In recent years, with the rapid development of artificial intelligence technology, machine vision-based food processing defect detection equipment has been widely used in the food industry. This type of equipment uses deep learning algorithms to analyze the food surface in real time, and can efficiently identify various defects such as foreign objects, color differences, and deformations, greatly improving the automation level and consistency of food quality control. Especially in the field of new material testing, the demand for quality testing of new food raw materials, functional foods, and special packaging materials is increasing. Accurate identification of the optical properties of different materials through multispectral imaging, hyperspectral analysis, and other technologies has become a key technology direction for improving detection accuracy and expanding the detection range. However, existing technologies mostly focus on the detection of finished products after demolding or before packaging, and there is relatively little research on the detection of semi-finished products that are still in the process of processing.

[0003] In industrial cake production, baked cakes are usually placed in molds to cool, and then demolded by flipping them over. However, the surface quality of multiple cakes in the same mold often varies, and some cakes may have defects such as surface collapse or local burning. Furthermore, when the cake is demolded, it flips over with the mold, and the upper surface that was originally to be inspected becomes the lower surface and comes into direct contact with the conveyor belt. This makes it difficult to effectively image and inspect the original upper surface after demolding. At the same time, defective cakes are very easy to break during demolding, which further increases the difficulty of tracing the source of defects. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a food processing defect detection device based on artificial intelligence recognition.

[0012] Preferably, there are two pallets, with the lower ends of the two pallets contacting the upper end of the base box, and the two pallets located on one side of the two connecting plates respectively.

[0013] Preferably, the upright plate is arranged in an inverted U-shape, and transverse slide rails are evenly connected between the two upright plates.

[0014] Preferably, the gas supply mechanism includes a vacuum generator, the lower end of which is connected to one side of the upper end of the lifting plate. The output end of the vacuum generator is connected to a connecting pipe, and one end of the connecting pipe is connected to a horizontal pipe. The horizontal pipe is fixed above the lifting plate by a mounting block. The lower end of the horizontal pipe is connected to a gas supply pipe at each of the three adsorption mechanisms. The lower ends of the three gas supply pipes extend through to the lower part of the lifting plate and are respectively connected to the upper ends of the three suction cups. The middle part of the gas supply pipe is set as a flexible tube. A protective frame is connected to the lower end of the lifting plate at the gas supply pipe. The middle part of the gas supply pipe is located inside the protective frame. A groove is opened in the middle of the lower end of the protective frame.

A discharge pipe is connected to the middle of one side of the cleaning box, and the discharge pipe is inclined.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention places the visual inspection mechanism before the cake flipping and demolding process, performing surface defect detection while the cake is still in its fixed position within the mold. At this time, the upper surface of the cake is fully exposed and unobstructed, providing superior imaging conditions and accurately identifying surface collapse and burnt defects. This effectively avoids the problem in traditional processes where the upper surface of the cake flips to the lower surface after demolding, making direct imaging impossible. It also reduces the risk of secondary breakage of defective cakes due to vibration or pressure during demolding. The selection mechanism employs three independently controlled suction mechanisms, which can flexibly adjust the suction cup position according to the defect coordinates. When there is no defective cake in the area corresponding to a certain suction mechanism, the suction cup moves to the far side to avoid the normal cake area, preventing indentation or contamination of the perfect cake. When a defective cake is present, the suction cup is precisely moved to directly above the defective cake, and a buffer spring absorbs excess downward pressure to achieve flexible contact, reducing surface damage caused by hard impacts.

[0019] This invention employs a dual cleaning mechanism combining positive pressure blowing and rotary scraping to effectively clean the lower surface of the suction cup. A moving mechanism moves the suction cup into the cleaning box, where a flexible scraper rotates to remove residual cake crumbs and grease from the suction cup surface. Simultaneously, positive pressure airflow assists in the removal process. Waste is then discharged through a guide block and discharge pipe, which helps reduce the contamination of subsequent cakes by residues on the suction cup surface and meets the hygiene requirements of food processing equipment.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-8 The food processing defect detection device based on artificial intelligence recognition shown includes a base box 1. A conveying mechanism is connected to the middle of the upper end of the base box 1. The conveying mechanism is used to convey the mold. A centering mechanism is connected to one side above the conveying mechanism. A detection mechanism is connected to the upper end of the base box 1 corresponding to the side above the conveying mechanism. The detection mechanism is used to detect the surface of the cake inside the mold. A selection mechanism is connected to the middle of the base box 1. The selection mechanism is used to select out the cakes with defects in the mold.

[0032] The selection mechanism includes a tray 11, a moving mechanism connected to one side of the upper end of the two trays 11, a lifting plate 17 connected below the moving mechanism, an adsorption mechanism connected to the lower end of each lifting plate 17, and three sets of adsorption mechanisms. A gas delivery mechanism is connected to one side of the upper end of the lifting plate 17.

[0033] The adsorption mechanism includes an adjusting slide rail 18, a movable block 19 slidably connected to one side of the adjusting slide rail 18, a sliding plate 20 slidably connected to one side of the movable block 19, a suction cup 23 connected to one end of the sliding plate 20, and a filter block connected to the pipe on the inner wall of the suction cup 23 to prevent cake crumbs from entering the gas delivery mechanism.

[0034] One of the trays 11 is connected to a waste bin 29 on one side of its upper end, and the other tray 11 is connected to a cleaning mechanism on its upper end. The cleaning mechanism is used to clean the suction cup 23.

[0035] The conveying mechanism is used to transport the mold tray containing cakes. The centering mechanism centers the mold tray to ensure that it enters the inspection station in a precise position. The inspection mechanism is used to perform optical imaging on the surface of each cake in the mold tray. Through the built-in artificial intelligence recognition algorithm, it analyzes whether the cake has surface collapse or burning defects and outputs the precise coordinates of the defective cake in the mold tray. The sorting mechanism removes the defective cake from the mold tray according to the inspection results.

[0036] Each of the three adsorption mechanisms is used to pick up a defective cake. The air supply mechanism provides negative pressure suction or positive pressure blowing to the suction cup 23. The suction cup 23 can float vertically. The waste bin 29 is used to collect defective cakes. The cleaning mechanism is located above another tray 11 and is used to clean the surface of the suction cup 23 to prevent cross-contamination. The adjusting slide rail 18 and the transverse slide rail 13 are both electrically controlled slide rails.

[0037] like Figure 1 and Figure 5 As shown: The conveying mechanism includes two connecting plates 2. Each connecting plate 2 is rotatably connected to a roller. The outer walls of the two rollers are connected to a conveyor belt 3. One of the rollers is connected to a drive motor on one side.

[0038] Two connecting plates 2 are set parallel to each other on the upper end of the bottom box 1 to form the frame of the conveying mechanism. The conveyor belt 3 is sleeved on the outer wall of the two rotating rollers. During operation, the drive motor drives the rotating rollers to rotate and drives the conveyor belt 3 to circulate. The mold plate is placed on the upper surface of the conveyor belt 3 and passes through the centering mechanism, the detection mechanism and the sorting mechanism in sequence.

[0039] like Figure 1 and Figure 5 As shown: The centering mechanism includes two support plates 4. The lower ends of the two support plates 4 are in contact with the upper ends of the two connecting plates 2 respectively. Pushing cylinders 5 are connected to the middle of one side of the two support plates 4. One end of the two pushing cylinders 5 extends through to one side of the two support plates 4 respectively. One end of the two pushing cylinders 5 is connected to an adjusting plate 6. The two adjusting plates 6 slide above the conveyor belt 3, and the two adjusting plates 6 ensure that the mold is in the middle of the upper part of the conveyor belt 3.

[0040] When the mold plate moves to the centering mechanism position, the two push cylinders 5 extend synchronously, pushing the adjustment plate 6 to gently push the mold plate from both sides, so that it is centered in the width direction of the conveyor belt 3. After the positioning is completed, the push cylinders 5 retract and the mold plate continues to be conveyed forward. The centering mechanism ensures that the center line of the mold plate is aligned with the optical center line of the detection mechanism, avoiding detection blind spots or coordinate errors.

[0041] like Figure 1 and Figure 5As shown: The inspection mechanism includes a gantry 7, which is located on one side above the conveying mechanism. Lifting cylinders 8 are evenly connected to the upper end of the gantry 7. The lower ends of the two lifting cylinders 8 extend through to the lower end of the gantry 7. The lower ends of the two lifting cylinders 8 are connected to a moving plate 9. Visual inspection equipment 10 is evenly connected to one side of the moving plate 9.

[0042] The gantry frame 7 is positioned above the conveyor belt 3. When the mold tray is transported to the inspection station and stops, the lifting cylinder 8 extends, driving the vision inspection device 10 to descend to the preset shooting height, triggering the capture of images of the top surfaces of all cakes in the mold tray. The images are transmitted to the industrial control computer, where the built-in deep learning model distinguishes between collapses and foreign objects based on morphological and color features, determines the degree of baking, and outputs the coordinates of defective cakes. After the shooting is completed, the lifting cylinder 8 drives the vision inspection device 10 to rise and reset.

[0043] There are two pallets 11. The lower ends of the two pallets 11 are in contact with the upper end of the base box 1. The two pallets 11 are located on one side of the two connecting plates 2 respectively.

[0044] Two pallets 11 are symmetrically arranged on both sides of the width direction of the conveyor belt 3, with sufficient space between the two pallets 11 for the conveyor belt 3 and the mold plate to pass through. The height of their upper surfaces matches the upper surface of the conveyor belt 3, ensuring that the suction cup 23 can move freely above the conveyor belt 3 and above the pallets 11.

[0045] like Figure 2 and Figure 6 As shown: The upright plate 12 is arranged in an inverted U-shape. Horizontal slide rails 13 are evenly connected between the two upright plates 12. Sliding sliders 14 are slidably connected to one side of the two horizontal slide rails 13. Connecting blocks 15 are connected to the lower part of one side of the two sliding sliders 14. Electric telescopic rods 16 are connected to the middle of the upper end of the two connecting blocks 15. The lower ends of the two electric telescopic rods 16 extend through to the bottom of the two connecting blocks 15. The lower ends of the two electric telescopic rods 16 are connected to the upper sides of the lifting plate 17.

[0046] Two horizontal slide rails 13 are set in parallel, and the slider 14 can move back and forth along the horizontal slide rails 13. The slider 14 and the horizontal slide rails 13 can realize the horizontal positioning of the lifting plate 17. The electric telescopic rod 16 drives the lifting plate 17 to rise and fall vertically. This moving mechanism cooperates with the longitudinal movement of the conveyor belt 3 to cover all cake coordinates in the mold tray.

[0047] like Figures 3-4As shown: The gas supply mechanism includes a vacuum generator 27. The lower end of the vacuum generator 27 is connected to one side of the upper end of the lifting plate 17. The output end of the vacuum generator 27 is connected to a connecting pipe 28. One end of the connecting pipe 28 is connected to a horizontal pipe 24. The horizontal pipe 24 is fixed above the lifting plate 17 by a mounting block. The lower end of the horizontal pipe 24 is connected to a gas supply pipe 25 corresponding to the three adsorption mechanisms. The lower ends of the three gas supply pipes 25 extend through to the lower part of the lifting plate 17 and are respectively connected to the upper ends of the three suction cups 23. A protective frame 26 is connected to the lower end of the lifting plate 17 corresponding to the gas supply pipe 25. The middle part of the gas supply pipe 25 is located inside the protective frame 26. A groove is opened in the middle of the lower end of the protective frame 26. The lower end of the gas supply pipe 25 extends to the lower part of the protective frame 26 through the groove. The protective frame 26 is used to protect the gas supply pipe 25. The section of the gas supply pipe 25 inside the protective frame 26 is a flexible hose, and the section from the lower part of the protective frame 26 to the suction cup 23 is a rigid gas pipe.

[0048] The vacuum generator 27 integrates a dual-function solenoid valve. Its air inlet is connected to an external compressed air source, and its output end is connected to the horizontal pipe 24 through the connecting pipe 28. The lower end of the horizontal pipe 24 has three air passage interfaces, which are connected to the upper end of the corresponding suction cup 23 through the air supply pipe 25. The middle part of the air supply pipe 25 is made of flexible hose to adapt to the bending deformation when the suction cup 23 moves horizontally. The protective frame 26 is located at the lower end of the lifting plate 17 and accommodates the middle part of the air supply pipe 25. The lower end has a sliding groove for the air supply pipe 25 to extend out, which serves as a protection function. During operation, the vacuum generator 27 switches to negative pressure mode during the adsorption stage, and the suction cup 23 adsorbs the cake. During the release stage, it switches to positive pressure mode to blow the cake into the waste box 29 and the surface of the suction cup 23 can be cleaned by positive pressure.

[0049] like Figure 4 As shown: The movable block 19 is arranged in an inverted L-shape. A stabilizing block is connected to the upper part of one side of the movable block 19. A sliding rod 21 is connected to the upper side of the stabilizing block. The lower end of the sliding rod 21 extends through to the lower end of the stabilizing block. The lower end of the sliding rod 21 is connected to the upper side of the sliding plate 20. A buffer spring 22 is connected to the lower part of the outer wall of the sliding rod 21. The lower end of the buffer spring 22 contacts the upper side of the sliding plate 20. The upper end of the buffer spring 22 is connected to the lower end of the stabilizing block.

[0050] When the suction cup 23 descends and contacts the cake, if the descent stroke is slightly excessive, the buffer spring 22 is compressed to absorb the excess downward pressure, so that the suction cup 23 makes flexible contact with the cake, avoiding hard impact that could cause indentations or breakage on the cake surface, while ensuring that the suction cup 23 adheres well to the cake surface.

[0051] During operation, the control system determines whether there is a defective cake in the corresponding area of ​​each adsorption mechanism based on the defect coordinates. If there is no defect, the moving block 19 moves to the sidemost side along the adjusting slide rail 18, so that the suction cup 23 completely avoids the normal cake area. When the lifting plate 17 descends, the suction cup 23 is suspended outside the mold plate to avoid damaging the normal cake. If there is a defect, the moving block 19 moves the suction cup 23 directly above the defective cake. The lifting plate 17 descends so that the suction cup 23 contacts the cake surface. When the descent stroke slightly exceeds the limit, the buffer spring 22 is compressed to absorb the excess downward pressure, achieving flexible contact and avoiding hard impact that could cause cake indentation or breakage. At the same time, it ensures that the suction cup 23 fits well with the cake surface.

[0052] like Figures 7-8 As shown: The cleaning mechanism includes a cleaning box 30, the lower end of which is connected to the upper end of the corresponding pallet 11. A guide block 31 is connected to the lower end of the inner wall of the cleaning box 30. The guide block 31 is inclined. A rotating shaft 34 is rotatably connected to the lower end of the cleaning box 30. The upper ends of multiple rotating shafts 34 pass through the cleaning box 30 and the guide block 31 in sequence and extend above the guide block 31. A rotating rod 32 is connected to the upper end of multiple rotating shafts 34. A scraper 33 is connected to the upper end of multiple rotating rods 32. The scraper 33 is made of flexible material and its shape is adapted to the shape of the suction cup 23. A transmission gear 35 is connected to the outer wall of each of the three rotating shafts 34. The three transmission gears 35 are connected by a transmission belt 36. A cleaning motor 39 is connected to the lower end of one of the rotating shafts 34. Inclined blocks 37 are connected to both sides of the upper end of the guide block 31. A discharge pipe 38 is connected to the middle of one side of the cleaning box 30. The discharge pipe 38 is inclined.

[0053] The inclined guide block 31 is used to guide waste. During operation, the moving mechanism moves the suction cup 23 above the cleaning box 30 and moves the suction cup 23 to the center of the transverse slide rail 13 to ensure that the suction cup 23 and the scraper 33 are precisely aligned and in contact. Then the suction cup 23 moves above the cleaning box 30 and descends to contact the scraper 33. The cleaning motor 39 drives the scraper 33 to rotate, scraping off the cake crumbs and grease remaining on the surface of the suction cup 23. The waste is discharged through the guide block 31 and the discharge pipe 38.

[0054] It should be noted that the drive motor, electric telescopic rod 16, transverse slide rail 13, adjusting slide rail 18, vision inspection device 10, vacuum generator 27, cleaning motor 39, push cylinder 5, lifting cylinder 8 and other actuators and control elements involved in the embodiments of the present invention, as well as the specific circuit connection, control logic and programming method of the control system, are all conventional technical means in the field and belong to the scope of prior art. Those skilled in the art can select appropriate models and perform conventional circuit design and program development according to actual needs. The specific working principle will not be described in detail here.

[0055] Working principle: After the equipment is started, the mold tray containing the cake is placed on the upper surface of the conveyor belt 3. The drive motor drives the rotating roller to rotate, which drives the conveyor belt 3 to circulate and transport the mold tray forward. When the mold tray moves to the centering mechanism position, the two push cylinders 5 extend synchronously and push the adjustment plate 6 to gently push the mold tray from both sides to center it in the width direction of the conveyor belt 3. After the positioning is completed, the push cylinders 5 retract, the adjustment plate 6 resets, and the mold tray continues to be transported forward to the inspection station.

[0056] Once the mold tray is transported to the inspection station and stops, the vision inspection device 10 triggers a photo capture to obtain images of the top surfaces of all cakes in the mold tray, analyzes whether the cakes have surface collapse or burnt defects, and outputs the precise coordinates of the defective cakes in the mold tray.

[0057] After the mold tray stops at the selection station, the control system determines whether there are defective cakes in the corresponding areas of each adsorption mechanism based on the defect coordinates output by the vision inspection mechanism. The slider 14 moves along the horizontal slide rail 13, driving the lifting plate 17 to be horizontally positioned to the corresponding position. If there are no defective cakes in the row or column corresponding to a certain adsorption mechanism, the moving block 19 moves along the adjusting slide rail 18 to the side, so that the suction cup 23 completely avoids the normal cake area. If there are defective cakes, the moving block 19 drives the suction cup 23 to move directly above the defective cake. After positioning, the electric telescopic rod 16 extends, driving the lifting plate 17 to descend, so that the suction cup 23 contacts the cake surface. When the suction cup 23 descends and contacts the cake, if the descent stroke slightly exceeds the limit, the buffer spring 22 is compressed to absorb the excess downward pressure, achieving flexible contact and avoiding damage to the cake surface caused by hard impact.

[0058] After the suction cup 23 contacts the cake surface, the vacuum generator 27 switches to negative pressure mode, generating negative pressure. This negative pressure is transmitted to the suction cup 23 through the connecting pipe 28, horizontal pipe 24, and air supply pipe 25, adsorbing and lifting the defective cake. Then, the electric telescopic rod 16 retracts, causing the suction cup 23 to rise and remove the defective cake from the mold. The slider 14 moves along the horizontal slide rail 13, moving the suction cup 23 above the waste bin 29. The vacuum generator 27 switches to positive pressure mode, blowing positive pressure airflow through the air supply pipe 25 to the suction cup 23, blowing the cake into the waste bin 29. At the same time, the positive pressure airflow performs preliminary cleaning on the surface of the suction cup 23.

[0059] After the defective cake is released, the slider 14 moves the suction cup 23 above the cleaning box 30 and positions it at the center of the transverse slide rail 13, ensuring precise alignment between the suction cup 23 and the scraper 33. The electric telescopic rod 16 extends, driving the suction cup 23 to descend and contact the scraper 33. The cleaning motor 39 starts, driving the three rotating shafts 34 to rotate synchronously via the transmission gear 35 and the transmission belt 36, which in turn rotates the rotating rod 32 and the scraper 33. The flexible scraper 33 generates relative friction with the surface of the suction cup 23. The process involves scraping away residual cake crumbs and grease. Simultaneously, the vacuum generator 27 switches to positive pressure mode, blowing positive pressure airflow into the suction cup 23 through the air supply pipe 25. This airflow, combined with the rotating scraping action of the scraper 33, blows the loosened crumbs away from the surface of the suction cup 23. The scraped waste falls into the guide block 31, slides along its inclined surface to the discharge pipe 38, and is discharged into the cleaning box 30 for collection. After cleaning is completed, the electric telescopic rod 16 retracts, and the suction cup 23 rises to its reset position, ready for the next suction operation.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
