Description

Technical Field

[0001] This application relates to the field of corrugated cardboard inspection technology, and in particular to an intelligent detection device for surface defects of corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet", "corrugated paper", "corrugated core", "corrugated base paper") and one layer of cardboard (also known as "boxboard"). It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and the cardboard, and the structure of the carton itself.

[0003] As a basic material in the packaging industry, the surface quality of corrugated cardboard directly affects the appearance and strength of the finished product. Currently, the industry generally uses manual sampling or traditional photoelectric sensor detection. Manual detection is inefficient and has a high rate of missed detection, while traditional photoelectric sensors can only identify obvious color difference defects and are not sensitive enough to fine structural defects (such as shallow indentations).

[0004] Manual inspection is highly subjective and inefficient, and traditional sensors cannot achieve simultaneous multi-dimensional defect detection, which needs further improvement.

[0005] Therefore, this application proposes an intelligent detection device for surface defects of corrugated cardboard. Utility Model Content

[0006] This application proposes an intelligent detection device for surface defects of corrugated cardboard to solve the problems mentioned in the background art. By setting up a conveying component, a detection component, a rejection component, and a collection component, a series of operations including conveying, detecting, and rejecting corrugated cardboard with defects are performed. Compared with manual inspection, this device solves the problems of low efficiency and high missed detection rate, as well as the problem that traditional photoelectric sensors can only identify obvious color difference defects and are not sensitive enough to fine structural defects (such as shallow indentations). This improves the detection efficiency and the accuracy of detecting defective products, greatly enhancing the practicality of the device.

[0007] To achieve the above objectives, this application adopts the following technical solution: A smart detection device for surface defects of corrugated cardboard includes a conveying component, a detection component, a rejection component, and a collection component. The detection component is arranged above the conveying component, the rejection components are arranged on both sides of the conveying component, and the collection component is arranged on one side of the conveying component. The detection component includes a fixed frame and a camera. The camera is fixedly connected to the fixed frame and electrically connected to an external control system.

[0008] In a preferred embodiment, the conveying assembly includes a conveyor frame and a conveyor belt, the conveyor belt being rotatably connected inside the conveyor frame, and the camera being located above the conveyor belt; By setting up a conveyor assembly, the conveyor frame is fixed to the ground, and a conveyor belt is installed inside the conveyor frame to transport corrugated cardboard, ensuring that the corrugated cardboard reaches below the camera, thereby improving the practicality of the device.

[0009] In a preferred embodiment, the rejection assembly includes a mounting frame, an electric cylinder, and a push plate. The mounting frame is fixedly connected to the outside of the conveyor frame, and the electric cylinder is fixedly connected to the mounting frame. The electric cylinder is electrically connected to an external control system. By activating the electric cylinder, the pusher plate is driven to push the corrugated cardboard on the conveyor belt, thus pushing the cardboard towards the movable plate, thereby improving the practicality of the device.

[0010] In a preferred embodiment, a push plate is slidably connected to the conveyor frame, and the telescopic end of the electric cylinder is fixedly connected to the push plate. By coordinating with the push plate, the electric cylinder will be activated immediately upon receiving a signal. The electric cylinder will then drive the push plate to push the defective corrugated cardboard out of the conveyor belt, thereby improving the practicality of the device.

[0011] In a preferred embodiment, the rejection assembly further includes a movable plate, connecting rods, and a torsion spring. Connecting rods are fixedly connected to both sides of the movable plate, and the movable plate is rotatably connected to the conveyor frame through the connecting rods. By pushing the push plate, the movable plate will rotate away from the push plate under the action of the thrust, so that the corrugated cardboard is pushed out of the conveyor belt, thereby improving the practicality of the device.

[0012] In a preferred embodiment, torsion springs are provided on the outside of both connecting rods, one end of each torsion spring is fixedly connected to the movable plate, and the other end is fixedly connected to the conveyor frame. By setting torsion springs on the connecting rods on both sides of the movable plate, the movable plate can rotate and automatically reset, improving its performance and thus enhancing the practicality of the device.

[0013] In a preferred embodiment, the collection assembly includes a collection box, a placement plate, and telescopic springs. The placement plate is slidably connected inside the collection box, and telescopic springs are provided around the bottom of the placement plate. The bottom end of each telescopic spring is fixedly connected to the bottom end of the collection box. By installing a placement plate inside the collection box and a telescopic spring between the placement plate and the collection box, the placement plate has a certain elasticity. As defective corrugated cardboard continues to accumulate, the placement plate slowly descends, ensuring that the corrugated cardboard does not experience a large drop when falling from the conveyor belt. This ensures that the corrugated cardboard falls stably into the collection box without tilting, thereby increasing the storage space of the collection box and improving the practicality of the device.

[0014] The beneficial effects of this application are: 1. This intelligent detection device for surface defects of corrugated cardboard, by setting up a conveying component, a detection component, a rejection component and a collection component, conveys, detects and rejects corrugated cardboard with defects through a series of operations. Compared with manual detection, it solves the problems of low efficiency and high missed detection rate, as well as the problem that traditional photoelectric sensors can only identify obvious color difference defects and are not sensitive enough to fine structural defects (such as shallow indentations). It improves detection efficiency and accuracy of detecting defective products, and greatly enhances the practicality of the device. 2. This intelligent detection device for surface defects of corrugated cardboard uses a placement plate with a telescopic spring between the placement plate and the collection box. This gives the placement plate a certain elasticity, allowing it to slowly descend as defective corrugated cardboard accumulates. This ensures that the corrugated cardboard does not fall too far from the conveyor belt, allowing it to fall stably into the collection box without tilting. This increases the storage space of the collection box and greatly enhances the practicality of the device. Attached Figure Description

[0018] Reference Figure 1-4 A smart detection device for surface defects of corrugated cardboard includes a conveying component 1, a detection component 2, a rejection component 3, and a collection component 4. The detection component 2 is arranged above the conveying component 1, the rejection components 3 are arranged on both sides of the conveying component 1, and the collection component 4 is arranged on one side of the conveying component 1. The detection component 2 includes a fixing frame 21 and a camera 22. The camera 22 is fixedly connected to the fixing frame 21 and is electrically connected to an external control system.

[0019] Reference Figure 1-3 The conveying assembly 1 includes a conveying frame 11 and a conveyor belt 12. The conveyor belt 12 is rotatably connected inside the conveying frame 11, and the camera 22 is located above the conveyor belt 12. By setting the conveying assembly 1, the conveying frame 11 is fixed on the ground, and the conveyor belt 12 is installed inside the conveying frame 11. The conveyor belt 12 is used to convey corrugated cardboard, ensuring that the corrugated cardboard reaches below the camera 22, thereby improving the practicality of the device.

[0020] Reference Figure 1-3 The rejection assembly 3 includes a mounting frame 31, an electric cylinder 32, and a push plate 33. The mounting frame 31 is fixedly connected to the outside of the conveyor frame 11, and the electric cylinder 32 is fixedly connected to the mounting frame 31. The electric cylinder 32 is electrically connected to an external control system. By activating the electric cylinder 32, the push plate 33 is driven to push the corrugated cardboard on the conveyor belt 12, pushing the corrugated cardboard towards the movable plate 34, thereby improving the practicality of the device.

[0021] Reference Figure 1-3 A push plate 33 is slidably connected to the conveyor frame 11, and the telescopic end of the electric cylinder 32 is fixedly connected to the push plate 33. By starting the electric cylinder 32, the push plate 33 is driven by the electric cylinder 32 to push the corrugated cardboard on the conveyor belt 12, and push the corrugated cardboard towards the movable plate 34, thereby improving the practicality of the device.

[0022] Reference Figure 1-3 The rejection assembly 3 also includes a movable plate 34, a connecting rod 35, and a torsion spring 36. The connecting rod 35 is fixedly connected to both sides of the movable plate 34, and the movable plate 34 is rotatably connected to the conveyor frame 11 through the connecting rod 35. By pushing the push plate 33, the movable plate 34 will rotate away from the push plate 33 under the action of the pushing force, so that the corrugated cardboard is pushed out of the conveyor belt 12, thereby improving the practicality of the device.

[0023] Reference Figure 1-3Both connecting rods 35 are equipped with torsion springs 36 on their exterior. One end of each torsion spring 36 is fixedly connected to the movable plate 34, and the other end is fixedly connected to the conveyor frame 11. By setting torsion springs 36 on the connecting rods 35 on both sides of the movable plate 34, the movable plate 34 can rotate and automatically reset, improving the performance and thus enhancing the practicality of the device.

[0024] Reference Figure 1 , 4 The collection component 4 includes a collection box 41, a placement plate 42, and telescopic springs 43. The placement plate 42 is slidably connected inside the collection box 41. Telescopic springs 43 are arranged around the bottom of the placement plate 42, and the bottom end of each telescopic spring 43 is fixedly connected to the bottom end of the collection box 41. By setting the placement plate 42 inside the collection box 41 and setting the telescopic springs 43 between the placement plate 42 and the collection box 41, the placement plate 42 has a certain elasticity. Under the continuous accumulation of defective corrugated cardboard, the placement plate 42 slowly descends, ensuring that the corrugated cardboard does not have a large drop when falling from the conveyor belt 12. This ensures that the corrugated cardboard can fall stably into the collection box 41 without tilting, thereby increasing the storage space of the collection box 41 and improving the practicality of the device.

[0025] Working principle: Corrugated cardboard is conveyed towards camera 22 via conveyor belt 12. When the cardboard reaches below camera 22, camera 22 performs a comprehensive inspection. When camera 22 detects a defective cardboard, it sends a signal to the external control system. Upon receiving the signal, the external control system activates electric cylinder 32, which drives push plate 33 to push the cardboard on conveyor belt 12 towards movable plate 34. Under the force of the push, movable plate 34 rotates away from push plate 33, causing the cardboard to exit conveyor belt 12 and fall onto placement plate 42 in collection box 41. This series of operations, including conveying, inspection, and rejection of defective cardboard, solves the problems of low efficiency and high missed detection rate compared to manual inspection. It also addresses the issue that traditional photoelectric sensors can only identify obvious color difference defects and are not sensitive enough to fine structural defects (such as shallow indentations), thus improving inspection efficiency and the accuracy of defective product detection.

[0026] By setting a placement plate 42 inside the collection box 41 and setting a telescopic spring 43 between the placement plate 42 and the collection box 41, the placement plate 42 has a certain elasticity. Under the continuous accumulation of defective corrugated cardboard, the placement plate 42 slowly descends, ensuring that the corrugated cardboard does not have a large drop when falling from the conveyor belt 12, ensuring that the corrugated cardboard can fall stably into the collection box 41, is not easy to tilt, and improves the storage space of the collection box 41.
