Description

Technical Field

[0001] The present invention relates to the technical field of machine vision detection, and in particular to a biscuit detection device based on machine vision. Background Art

[0002] Low-glycemic biscuits are specially designed for people who want to control their blood sugar or pay attention to healthy eating. This type of biscuit has a lower glycemic index by selecting specific ingredients and recipes, so that the blood sugar level rises more slowly and steadily after consumption. Low-glycemic foods are very suitable for diabetics, dieters, and people who pay attention to healthy eating. After the production of low-glycemic biscuits, it is usually necessary to inspect their size, damage, and whether they are burnt. The above inspection of biscuits is usually achieved using machine vision inspection devices.

[0003] The protection performance of common machine vision inspection devices on the market is poor. In the biscuit production workshop, the hot air and steam after the biscuits are baked can easily come into contact with the machine vision camera, which can easily cause damage to the camera or contamination of the lens, thus affecting the accuracy of the inspection. In addition, the existing machine vision inspection devices are very likely to be interfered by other color blocks (additives in the biscuits, pores in the biscuits, conveyor belt color, etc.) when identifying whether the biscuits are burnt, resulting in detection errors.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a biscuit detection device based on machine vision is proposed. Summary of the invention

[0007] Furthermore, the clamping assembly includes a first support seat, a first electric push rod and a clamping block, the first support seat is provided with the first electric push rod at the outer end, and the output end of the first electric push rod is connected to the clamping block.

[0008] Furthermore, the first support seat is arranged at both ends of the outside of the conveyor belt, and the first electric push rod pushes the clamping block to clamp the positioning block.

[0009] Furthermore, the inner contour of the positioning block matches the outer contour of the flexible pad, and a through opening matching the shape of the detection slot is provided on the surface of the flexible pad.

[0010] Furthermore, the second electric push rod drives the sliding plate and the color block plate to move, and the outer surface of the color block plate fits with the inner surface of the flexible pad.

[0011] Furthermore, the visual inspection component includes a second support seat, an inspection box, light-transmitting glass, an electric-controlled screw rod, a sliding seat, a visual inspection camera, a first slide groove, a connecting block, a synchronous seat, a cleaning brush and a second slide groove, the outer end of the second support seat is connected to the inspection box, and the light-transmitting glass is arranged on the inner bottom of the inspection box, the electric-controlled screw rod is arranged on both sides of the interior of the inspection box, and the outer end of the electric-controlled screw rod is arranged on the sliding seat, and the outer end of the sliding seat is connected to the visual inspection camera, the interior of the inspection box is provided with a first slide groove, and the bottom end of the inspection box is provided with a second slide groove, the outer end of the sliding seat is connected to the connecting block, and the connecting block is connected to the synchronous seat on the side away from the sliding seat, and the bottom end of the synchronous seat is connected to the cleaning brush.

[0012] Furthermore, the visual inspection camera and the positioning block are distributed vertically, and the positioning block and the conveyor belt surface are distributed parallelly.

[0013] Furthermore, the electric control screw drives the sliding seat and the visual detection camera to move, and the sliding seat is fixed to the synchronous seat through the connecting block.

[0014] Furthermore, the connecting block slides and moves inside the first sliding groove, and the connecting block drives the synchronous seat to move inside the second sliding groove.

[0015] Furthermore, the synchronous seat is fixedly connected to the cleaning brush, and the cleaning brush is in contact with the light-transmitting glass.

[0016] The present invention provides a biscuit detection device based on machine vision, which has the following beneficial effects:

[0017] 1. There is a height difference between the visual inspection camera and the positioning block of the present invention. After the perspective of the visual inspection camera, the size of the inspection slot will be equal to the size of the biscuit. After the biscuit moves to the bottom of the positioning block, the visual inspection camera shoots the biscuit through the inspection slot. Because the size of the inspection slot after perspective is consistent with the size of the biscuit, the visual inspection camera can clearly judge whether the size of the biscuit is qualified through reference and comparison of the inspection slot. In addition, during the demolding process of the baked biscuits, if the biscuits are damaged, the damaged parts will be separated from the body, and the inspection slot can also be clearly judged whether the biscuits are damaged. The positioning block pushes the clamping block to position and clamp and fix it through the first electric push rod. Through this design, the staff can replace the corresponding positioning blocks when producing different types of biscuits to achieve visual assisted detection, which makes the use of the equipment flexible. In addition, the clamping block can clamp three groups of positioning blocks. When the equipment produces biscuits of multiple different specifications at one time, the sliding seat is driven by the electric control screw rod to move, so that the visual inspection camera can be moved to the bottom of different positioning blocks for visual inspection, which makes the equipment adaptable to the visual inspection of biscuits of different specifications.

[0018] 2. The color block plate of the present invention is arranged inside the positioning block, so that the visual inspection camera shoots the biscuits through the color block plate. The color block plate is arranged alternately in transparent, bright yellow and bright red. When the visual inspection camera shoots the size and regularity of the biscuits, the color block plate is in the transparent color block in the inspection slot. After the biscuit size and regularity are qualified, the second electric push rod works to enable the sliding plate to drive the color block plate to move. After the color block plate moves, the transparent color block can be changed to a bright yellow color block, and the visual inspection camera can then After the first shot is completed, the color block plate shifts again, causing the bright yellow block to become a bright red block. After the visual inspection camera completes the third shot, it will compare the colors of the three groups of color blocks. When dark brown is interlaced with bright yellow, it will appear olive green, and when dark brown is interlaced with bright red, it will appear brick red. Through this feature, when the biscuits appear burnt, by comparing multiple groups of color blocks, the device can accurately determine whether the biscuits are burnt, which can effectively avoid misjudgment of a single group of color judgments, which can greatly improve the detection accuracy of biscuits.

[0019] 3. Translucent glass is arranged at the bottom of the detection box of the present invention. The translucent glass can effectively isolate the relevant components of the visual detection camera and the biscuits, which can prevent the visual detection camera from contaminating the biscuits during the detection process. The multi-layer partition of the positioning block, the color block plate and the translucent glass can also effectively prevent the high-temperature biscuits after baking from affecting the normal operation of the visual detection camera. In addition, during the displacement of the color block plate, its surface can be in contact with the flexible pad. The flexible pad is made of sponge material. By wiping with the flexible pad, the water vapor and oil stains adhered to the surface of the color block plate can be effectively wiped off, which can prevent the water vapor and oil stains adhered to the surface of the color block plate from affecting its light transmittance and changing its original color, thereby affecting visual detection. During the displacement of the visual detection camera, the synchronous seat can be driven to move through the connecting block. During the displacement of the synchronous seat, the cleaning brush can be driven to slide on the surface of the translucent glass, which enables the cleaning brush to clean the translucent glass to avoid affecting the normal operation of the visual detection camera. Through this design, the equipment can automatically complete cleaning during normal operation to avoid affecting its detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific operation is as follows: the color block plate 9 is placed inside the positioning block 4, so that the visual inspection camera 1006 shoots the biscuits through the color block plate 9. The color block plate 9 is arranged alternately in transparent, bright yellow and bright red. When the visual inspection camera 1006 shoots the size and regularity of the biscuits, the color block plate 9 is in the transparent color block in the inspection slot 5. After the biscuit size and regularity are qualified, the second electric push rod 7 works to enable the sliding plate 8 to drive the color block plate 9 to move. After the color block plate 9 is moved, the transparent color block can be changed to a bright yellow color block, and the visual inspection camera 1006 can detect the size and regularity of the biscuits. After the detection camera 1006 completes shooting again, the color block plate 9 moves again, which will change the bright yellow color block into a bright red color block. After the visual detection camera 1006 completes the third shooting, it will compare the colors of the three groups of color blocks. When dark brown is interlaced with bright yellow, it will appear olive green, and when dark brown is interlaced with bright red, it will appear brick red. Through this feature, when the biscuits appear burnt, by comparing multiple groups of color blocks, the device can accurately determine whether the biscuits are burnt, which can effectively avoid the occurrence of misjudgment in the discrimination of a single group of colors, which can greatly improve the detection accuracy of biscuits.

[0029] See also Figures 1 to 3The clamping assembly 3 includes a first support seat 301, a first electric push rod 302 and a clamping block 303.

The inner contour of the positioning block 4 matches the outer contour of the flexible pad 6, and the surface of the flexible pad 6 is provided with a through hole matching the shape of the detection slot 5. The second electric push rod 7 drives the sliding plate 8 and the color block plate 9 to move, and the outer surface of the color block plate 9 fits the inner surface of the flexible pad 6.

[0030] The specific operation is as follows: the baking machine 2 moves the baked biscuits to the surface of the conveyor belt 1, and the conveyor belt 1 drives the baked biscuits to move, so that the biscuits can move to the bottom of the positioning block 4. After the biscuits move to the bottom of the positioning block 4, the conveyor belt 1 stops working. There is a height difference between the visual inspection camera 1006 and the positioning block 4. After the perspective of the visual inspection camera 1006, the size of the inspection slot 5 is equal to the size of the biscuits. After the biscuits move to the bottom of the positioning block 4, the visual inspection camera 1006 shoots the biscuits through the inspection slot 5. The size of the biscuits is consistent with that of the biscuits. Through the reference comparison of the detection slot 5, the visual detection camera 1006 can clearly judge whether the size of the biscuits is qualified. In addition, during the demoulding process of the baked biscuits, if the biscuits are damaged, the damaged parts will be separated from the body, and through the detection slot 5, it can also be clearly judged whether the biscuits are damaged. The positioning block 4 pushes the clamping block 303 to position and clamp and fix through the first electric push rod 302. Through this design, the staff can replace the corresponding positioning block 4 when producing different types of biscuits to achieve visual auxiliary detection, which makes the use of the equipment flexible.

[0031] See also Figures 4 to 6The visual inspection component 10 includes a second support seat 1001, an inspection box 1002, a light-transmitting glass 1003, an electric-controlled screw rod 1004, a sliding seat 1005, a visual inspection camera 1006, a first slide groove 1007, a connecting block 1008, a synchronous seat 1009, a cleaning brush 1010 and a second slide groove 1011. The outer end of the second support seat 1001 is connected with the inspection box 1002, and the light-transmitting glass 1003 is arranged on the inner bottom of the inspection box 1002. The electric-controlled screw rod 1004 is arranged on both sides of the interior of the inspection box 1002, and the outer end of the electric-controlled screw rod 1004 is arranged with a sliding seat 1005, and the outer end of the sliding seat 1005 is connected with the visual inspection camera 1006, the interior of the inspection box 1002 is provided with a first slide groove 1007, and the bottom of the inspection box 1002 is provided with a second slide groove 1 011, the outer end of the sliding seat 1005 is connected with a connecting block 1008, and the connecting block 1008 is connected with a synchronous seat 1009 on the side away from the sliding seat 1005, and the bottom end of the synchronous seat 1009 is connected with a cleaning brush 1010, the visual inspection camera 1006 and the positioning block 4 are vertically distributed, and the positioning block 4 and the surface of the conveyor belt 1 are parallelly distributed, the electric control screw 1004 drives the sliding seat 1005 and the visual inspection camera 1006 to move, and the sliding seat 1005 is fixed to the synchronous seat 1009 through the connecting block 1008, the connecting block 1008 slides and moves inside the first slide groove 1007, and the connecting block 1008 drives the synchronous seat 1009 to move inside the second slide groove 1011, the synchronous seat 1009 is fixedly connected to the cleaning brush 1010, and the cleaning brush 1010 fits with the light-transmitting glass 1003;

[0032] The specific operation is as follows: the clamping block 303 can hold three groups of positioning blocks 4 inside. When the equipment produces multiple biscuits of different specifications at one time (children's biscuits), the sliding seat 1005 is driven to move by the electric control screw rod 1004, so that the visual inspection camera 1006 can be moved to the bottom of different positioning blocks 4 for visual inspection, which enables the equipment to adapt to the visual inspection of biscuits of different specifications; the bottom of the inspection box 1002 is provided with a light-transmitting glass 1003, which can effectively isolate the relevant components of the visual inspection camera 1006 and biscuits, which can prevent the visual inspection camera 1006 from causing contamination to the biscuits during the inspection process, and the multi-layer partition of the positioning block 4, the color block plate 9 and the light-transmitting glass 1003 can also effectively prevent the high-temperature biscuits after baking from affecting the normal operation of the visual inspection camera 1006. In addition, the color block During the displacement of plate 9, its surface can come into contact with flexible pad 6. Flexible pad 6 is made of sponge material. By wiping with flexible pad 6, water vapor and oil stains adhered to the surface of color block plate 9 can be effectively wiped off, which can prevent water vapor and oil stains adhered to the surface of color block plate 9 from affecting its light transmittance and changing its original color, thereby affecting visual detection. During the displacement of visual detection camera 1006, it can drive synchronization seat 1009 to displace through connecting block 1008. During the displacement of synchronization seat 1009, it can drive cleaning brush 1010 to slide on the surface of light-transmitting glass 1003, which enables cleaning brush 1010 to clean light-transmitting glass 1003 to avoid affecting the normal operation of visual detection camera 1006. Through this design, the equipment can automatically complete cleaning during normal operation to avoid affecting its detection accuracy.

[0033] In summary, when the biscuit detection device based on machine vision is used, first, the baking machine 2 works to move the baked biscuits to the surface of the conveyor belt 1, and the conveyor belt 1 works to drive the baked biscuits to move, so that the biscuits can move to the bottom of the positioning block 4. After the biscuits move to the bottom of the positioning block 4, the conveyor belt 1 stops working. There is a height difference between the visual detection camera 1006 and the positioning block 4. After the perspective of the visual detection camera 1006, the size of the detection slot 5 is equal to the size of the biscuits. After the biscuits move to the bottom of the positioning block 4, the visual detection camera 1006 shoots the biscuits through the detection slot 5. Because the size of the perspective detection slot 5 is consistent with the size of the biscuits, the visual detection camera 1006 can clearly judge whether the size of the biscuits is qualified through the reference comparison of the detection slot 5. In addition, during the demoulding process of the baked biscuits, if the biscuits are damaged, the damaged part will be separated from the body, and the detection slot 5 can also clearly judge whether the biscuits are damaged.

[0034] Then, the positioning block 4 pushes the clamping block 303 to position and clamp it through the first electric push rod 302. With this design, the staff can replace the corresponding positioning block 4 when producing different types of biscuits to achieve visual assisted inspection, and the clamping block 303 can clamp three groups of positioning blocks 4 inside. When the equipment produces biscuits of multiple different specifications at one time, the sliding seat 1005 is driven to move by the electric control screw rod 1004, so that the visual inspection camera 1006 can be moved to the bottom of different positioning blocks 4 for visual inspection, so that the equipment can adapt to the visual inspection of biscuits of different specifications;

[0035] Then, when the visual inspection camera 1006 is shooting the biscuit size and regularity, the color block plate 9 is in the transparent color block in the inspection slot 5. After the biscuit size and regularity are qualified, the second electric push rod 7 works to enable the sliding plate 8 to drive the color block plate 9 to move. After the color block plate 9 moves, the transparent color block can be changed into a bright yellow color block. After the visual inspection camera 1006 completes the shooting again, the color block plate 9 moves again, which will change the bright yellow color block into a bright red color block. After the visual inspection camera 1006 completes the third shooting, it will compare the colors of the three groups of color blocks. When dark brown is interlaced with bright yellow, it will appear olive green, and when dark brown is interlaced with bright red, it will appear brick red. Through this feature, when the biscuits are burnt, the device can accurately judge whether the biscuits are burnt by comparing multiple groups of color blocks.

[0036] Finally, the light-transmitting glass 1003 inside the inspection box 1002 can effectively isolate the relevant parts of the visual inspection camera 1006 and the biscuits, which can prevent the visual inspection camera 1006 from contaminating the biscuits during the inspection process. The multi-layer partitions of the positioning block 4, the color block plate 9 and the light-transmitting glass 1003 can also effectively prevent the high-temperature biscuits after baking from affecting the normal operation of the visual inspection camera 1006. In addition, during the displacement process of the color block plate 9, its surface can be in contact with the flexible pad 6. The flexible pad 6 is made of sponge material. By wiping the flexible pad 6, it can effectively Wipe off the water vapor and oil stains adhering to the surface of the color block plate 9. This can prevent the water vapor and oil stains adhering to the surface of the color block plate 9 from affecting its light transmittance and changing its original color, thereby affecting visual detection. During the displacement of the visual detection camera 1006, it can drive the synchronization seat 1009 to displace through the connecting block 1008. During the displacement of the synchronization seat 1009, it can drive the cleaning brush 1010 to slide on the surface of the light-transmitting glass 1003, so that the cleaning brush 1010 can clean the light-transmitting glass 1003 to avoid affecting the normal operation of the visual detection camera 1006.
