Description

Technical Field

[0001] This utility model belongs to the technical field of appearance inspection devices, specifically, it relates to a visual inspection device for the appearance of corn wafer tubes. Background Technology

[0002] Corn wafer cones are cylindrical with an opening on the left and a conical surface on the right. They are made of brittle and fragile wafer sheets and are designed to resemble corn. They are often used in the production of corn-flavored ice cream. However, due to issues such as mold mismatch or impacts during the production process, the appearance is often damaged. To ensure product quality, it is necessary to conduct appearance inspections on the corn wafer cones after production and before packaging and sales to remove defective products. Currently, factories mostly rely on manual inspection for appearance checks, which is slow, time-consuming, and labor-intensive. There is an urgent need to design a device to automate the visual inspection process, prevent defective products from leaving the factory, reduce manpower, and maintain brand reputation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a new technical solution:

[0004] A visual inspection device for the appearance of corn wafers includes a transport component, a front inspection mechanism, a back inspection mechanism, an internal inspection mechanism, a controller, and a rejection component.

[0005] The transport components include conveyor one, a tipping device, and conveyor two. Both conveyor one and conveyor two are push-plate type conveyors. The push-plate type conveyors have several grooved transport tracks parallel to the transport direction. Conveyor one is inclined upwards, and conveyor two is horizontally positioned to the right of conveyor one. The right end of conveyor one is higher than the left end of conveyor two. The tipping device supports the right end of conveyor one and the left end of conveyor two.

[0006] The tipping device includes a connecting plate, several cylinders, and a detection plate. The connecting plate has several grooved tracks that match the transport tracks. The connecting plate supports conveyor one and conveyor two. After the material is transported out of the transport track of conveyor one, it falls into the grooved tracks and slides into the transport track of conveyor two. The fixed end of cylinder one is fixedly connected to the bottom surface of the connecting plate, and the moving end of cylinder one is connected to the detection plate. The detection plate is set perpendicular to the connecting plate. The bottom of the grooved track in the middle of the connecting plate has an opening that matches the detection plate. Cylinder one controls the detection plate to pass through or out of the opening by telescopic control.

[0007] The front detection mechanism is located on the upper left side of conveyor one and includes several image acquisition devices and a support. The image acquisition devices correspond to the transport track and are fixedly mounted on the upper side of conveyor one via the support. The back detection mechanism is located on the lower right side of conveyor one and includes several image acquisition devices and a support. The image acquisition devices correspond to the transport track and are fixedly mounted on the lower side of conveyor one via the support. The transport track above the image acquisition devices is made of transparent material. The internal detection mechanism is located on the upper side of the connecting plate and includes several image acquisition devices and a support. The image acquisition devices correspond to the groove track and are fixedly mounted on the upper side of the connecting plate via the support. The image acquisition devices observe the interior of the corn wafer tube through the rear opening of the corn wafer tube.

[0008] The middle section of the conveyor is provided with a gap in the transport track. The rejection component is set in the gap in the transport track and includes several cylinders and movable parts. The movable parts are matched with the transport track and are correspondingly set in the gap in the transport track. The left end of the movable part is hinged to the left side of the transport track of the conveyor. The fixed end of the cylinder is hinged to the bottom of the left side of the transport track of the conveyor. The moving end of the cylinder is hinged to the bottom of the movable part. The retraction of the cylinder controls the movable part to rotate downward around the left side of the movable part, so that the corn wafer can on the movable part falls to the bottom of the transport track of the conveyor.

[0009] Cylinder 1, Cylinder 2, Image Acquisition Unit 1, Image Acquisition Unit 2, Image Acquisition Unit 3, Conveyor 1 and Conveyor 2 are all electrically connected to the controller.

[0010] Furthermore, conveyor one is equipped with sensor one inside the truss located below the support, conveyor one is equipped with sensor two inside the truss located above the support, conveyor one is equipped with sensor three inside the right truss of conveyor one, and conveyor two is equipped with sensor four inside the truss located in the empty section of the transport track.

[0011] Furthermore, sensor 1, sensor 2, sensor 3, and sensor 4 are all electrically connected to the controller.

[0012] Sensors 1, 2, 3, and 4 work in conjunction with conveyors 1 and 2 and the detection plate. When the corn wafer cans are transported to the corresponding positions of image collectors 1 and 2, they are triggered, sending signals to the controller. The controller then stops conveyors 1 and 2 until the image collectors 1 and 2 have completed their data collection and analysis. After that, the controller resumes the transport. When the corn wafer cans reach sensor 3, the controller extends the detection plate out of its opening. The bottom of the corn wafer cans contacts the detection plate and stops sliding on the connecting plate. After image collector 3 completes its data collection and analysis, the detection plate exits its opening, and the corn wafer cans continue sliding on the connecting plate and fall onto conveyor 2. Sensor 4 detects that there are no corn wafer cans on the connecting plate and extends its opening to perform the next detection.

[0013] This utility model also includes other devices or components that enable the visual inspection equipment for the appearance of corn wafer tubes to function properly, all of which are conventional technical means in the field. Furthermore, the controller and pusher-type conveyor not specified in this utility model also employ conventional technical means in the field.

[0014] The working principle of this utility model is as follows: In the front-end material management mechanism, the corn wafer tubes are sorted and conveyed onto a pusher conveyor, which then transports them to the inspection station. They first enter the first process, the front inspection mechanism, and then, upon entering the field of view of the image acquisition device, the image acquisition device is triggered to capture an image. The captured image is analyzed and processed to determine if there are any defects, and information on non-conforming products is recorded. The material is then conveyed to the second process, the back inspection mechanism, where images are triggered and captured. The captured images are analyzed and processed to determine if there are any defects, and information on non-conforming products is recorded. When the corn wafer tubes enter the third vision process, the internal inspection mechanism, the material is positioned by the inspection plate, the camera is triggered to take a picture, and information on defective products is recorded. Finally, the defective product information from the three processes is integrated, and the corn wafer tubes that do not meet the appearance requirements are rejected by the rejection component.

[0015] The beneficial effects of this utility model are that, compared with manual inspection, this device is more accurate, faster, and more convenient; the equipment is simple to operate, improves process management, and reduces missed inspections; it prevents defective products from flowing out, reduces manpower, and maintains brand reputation.

Conveyor 1 is inclined upwards, and conveyor 2 is horizontally positioned to the right of conveyor 1, with the right end of conveyor 1 higher than the left end of conveyor 2. The tipping device supports the right end of conveyor 1 and the left end of conveyor 2.

[0029] The tipping device includes a connecting plate 3, six cylinders 4, and a detection plate 5. The connecting plate 3 has six grooved tracks that match the transport tracks. The connecting plate 3 supports conveyor 1 and conveyor 2. After the material is transported out of the transport track of conveyor 1, it falls into the grooved tracks and slides into the transport track of conveyor 2. The fixed end of cylinder 4 is fixedly connected to the bottom surface of the connecting plate 3, and the moving end of cylinder 4 is connected to the detection plate 5. The detection plate 5 is set perpendicular to the connecting plate 3. The bottom of the grooved track in the middle of the connecting plate 3 has an opening 6 that matches the detection plate 3. The cylinders 4 control the detection plate 5 to pass through or out of the opening 6 by telescopic control.

[0030] The front detection mechanism is located on the upper left side of conveyor 1 and includes six image acquisition devices 7 and a bracket 8. The image acquisition devices 7 correspond to the transport track and are fixedly mounted on the upper side of conveyor 1 via the bracket 8. The back detection mechanism is located on the lower right side of conveyor 1 and includes six image acquisition devices 9 and a bracket 10. The image acquisition devices 9 correspond to the transport track and are fixedly mounted on the lower side of conveyor 1 via the bracket 10. The transport track above the image acquisition devices 9 is made of transparent material. The internal detection mechanism is located on the upper side of connecting plate 3 and includes six image acquisition devices 11 and a bracket 12. The image acquisition devices 11 correspond to the groove track and are fixedly mounted on the upper side of connecting plate 3 via the bracket 12. The image acquisition devices 11 observe the interior of the corn wafer tube through the rear opening of the corn wafer tube.

[0031] The middle section of the conveyor 2 has a gap in the transport track. The rejection component is set in the gap in the transport track and includes six cylinders 13 and a movable part 14. The movable part 14 matches the transport track and is set in the gap in the transport track. The left end of the movable part 14 is hinged to the left side of the transport track of the conveyor 2. The fixed end of the cylinder 13 is hinged to the bottom of the left side of the transport track of the conveyor 2. The moving end of the cylinder 13 is hinged to the bottom of the movable part 14. The retraction of the cylinder 13 controls the movable part 14 to rotate downward around the left side of the movable part 14, so that the corn wafer can on the movable part 14 falls to the bottom of the transport track of the conveyor 2.

[0032] Cylinder 1 (4), Cylinder 2 (13), Image Acquisition Unit 1 (7), Image Acquisition Unit 2 (9), Image Acquisition Unit 3 (11), Conveyor 1 (1), and Conveyor 2 (2) are all electrically connected to the controller.

When the corn wafer cans are transported to the corresponding positions of image collectors 7 and 9, sensors 15 and 16 are triggered, sending signals to the controller. The controller then stops conveyors 11 and 22 until image collectors 7 and 29 have completed their data collection and analysis. After this, the controller resumes the transport. When the corn wafer cans reach sensor 317, the controller extends the detection plate 5 out of the opening 6. The bottom of the corn wafer can contacts the detection plate 5 and stops sliding on the connecting plate 5. After image collector 311 completes its data collection and analysis, the detection plate 5 exits the opening 6, and the corn wafer can continues to slide on the connecting plate 5, falling onto conveyor 22. Sensor 418 detects the corn wafer cans on the empty section of the transport track, and the controller controls certain moving parts 14 to rotate, thus removing defective products.

[0035] The working principle of this utility model is as follows: In the front-end material handling mechanism, the corn wafer tubes are sorted and conveyed to the pusher conveyor, which then transports them to the inspection station. They first enter the first process, the front inspection mechanism, and then, upon entering the field of view of the image acquisition device 7, the image acquisition device is triggered to capture an image. The captured image is analyzed and processed to determine if there are any defects, and information on non-conforming products is recorded. The material is then conveyed to the second process, the back inspection mechanism, where images are triggered and captured. The captured images are analyzed and processed to determine if there are any defects, and information on non-conforming products is recorded. When the corn wafer tubes enter the third process, the internal inspection mechanism, the material is positioned by the inspection plate, the camera is triggered to take a picture, and information on defective products is recorded. Finally, the defective product information from the three processes is integrated, and the corn wafer tubes that do not meet the appearance requirements are rejected by the rejection component.
