Technical Field

[0001] This utility model applies to the field of aluminum foil detection technology for the inner frame of small boxes, and particularly relates to a visual imaging detection device for aluminum foil in the inner frame of small boxes. Background Technology

[0002] With the development of automated packaging technology for products such as cigarettes and pharmaceuticals, the aluminum foil inner frame of small boxes, as a key component of the packaging structure, directly affects the product's sealing performance, appearance quality, and consumer experience. In actual production, defects such as missing parts, wrinkles, and misalignments in the inner frame aluminum foil often occur due to mechanical conveying deviations, material deformation, or inaccurate positioning. Traditional inspection methods mainly rely on manual visual inspection, which suffers from low efficiency, high missed detection rates, and strong subjectivity, making it difficult to meet the real-time and accuracy requirements of high-speed automated production lines. Therefore, there is an urgent need for a visual imaging inspection device that can achieve rapid, accurate, and non-contact inspection to improve product quality control.

[0003] In order to solve the above-mentioned technical problems, this utility model designs a visual imaging detection device for aluminum paper inside a small box. Utility Model Content

[0004] This utility model provides a visual imaging detection device for aluminum foil in the inner frame of a small box, aiming to solve the problems of low efficiency, high missed detection rate, and strong subjectivity in traditional manual inspection of aluminum foil defects in the inner frame of small boxes. The technical solution is as follows: A visual imaging detection device for aluminum foil inner frame of a small box includes a conveying mechanism for conveying the small box and a visual imaging system. The visual imaging system includes a mounting column, a reversing mirror, a light source bracket, and a camera. The mounting column is fixedly connected to the inside of the outer shell, and a rotating plate is rotatably connected to the mounting column. The rotating plate has a rotating groove, and the reversing mirror is connected to the rotating plate. An adjustment plate is also fixedly connected to the mounting column. The adjustment plate has an adjustment groove, and the light source bracket is installed through the adjustment groove. The light source is installed on the light source bracket. The camera is installed on the adjustment plate.

[0005] Based on the above technical solution, the conveying mechanism is a turntable conveying assembly, including a turntable and a driving element. The turntable is provided with a station for placing small boxes, and a driving element is provided below the turntable for driving the turntable to rotate.

[0006] Preferably, the adjustment groove on the adjustment plate is elongated or arc-shaped, and the adjustment groove is arranged along the length direction of the adjustment plate. The light source bracket is fixed in the adjustment groove by fasteners, and the width of the adjustment groove matches the diameter of the fasteners.

[0007] Preferably, the rotating groove on the rotating plate has an arc-shaped structure, and the rotating plate is installed in the mounting column via a rotating shaft and the angle of the rotating plate can be adjusted around the rotating shaft.

[0008] Preferably, the assembly also includes a rejection component, comprising a rejection bracket and a rejection head. The rejection bracket is fixed to the bottom of the turntable by bolts. A rejection hole is provided on the workstation. The rejection head is connected to a rejection drive element for driving. The rejection drive element is a cylinder or an electric push rod.

[0009] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are: 1. By employing an adjustable visual imaging system (including angle-adjustable reversing mirrors and position-adjustable light sources) and a symmetrically arranged dual-camera design, the observation angle and illumination mode can be flexibly adjusted to achieve multi-angle imaging of the aluminum foil inside the small box. This effectively overcomes the blind spots of single-view detection, enabling more comprehensive and accurate identification of various defects such as missing aluminum foil, wrinkles, and misalignments, significantly reducing the false negative and false positive rates.

[0016] like Figure 1 As shown, a visual imaging detection device for aluminum paper inside a small box includes a conveying mechanism 1 for conveying the small box 13 and a visual imaging system 2.

[0017] like Figures 2 to 5 As shown, the visual imaging system 2 includes a mounting post 22, a reversing mirror 26, a light source bracket 251, and a camera 23. The mounting post 22 is fixedly connected to the inside of the housing 21. A rotating plate 27 is rotatably connected to the mounting post 22. The rotating plate 27 has a rotating groove 271. The reversing mirror 26 is connected to the rotating plate 27. By rotating the rotating plate 27, the angle of the reversing mirror 26 can be adjusted.

[0018] By adjusting the angle of the reversing lens 26, the reflection direction of the light path of the camera 23 can be changed, thereby flexibly adjusting the observation angle of the aluminum foil inside the small box. This allows for the acquisition of more comprehensive visual information for capturing defects in different directions, such as side wrinkles or bottom offsets. Adjusting the optical path eliminates the need to move the camera or product, ensuring a non-contact inspection process and preventing damage to the product.

[0019] The rotating groove 271 on the rotating plate 27 has an arc-shaped structure. The rotating plate 27 is mounted in the mounting column 22 via a rotating shaft and its angle can be adjusted around the rotating shaft. The reversing mirror 26 is fixed to the rotating plate 27, and the angle adjustment range of the reversing mirror 26 is from zero to thirty degrees. The rotating groove 271 is also provided with locking screws or knobs. After adjustment, tighten the fasteners to lock the rotating plate 27 in place through friction.

[0020] The arc-shaped rotating groove 271 provides precise guidance and a stable motion trajectory for the rotating plate 27 to rotate around the rotating axis.

[0021] An adjustment plate 24 is also fixedly connected to the mounting column 22. An adjustment groove 241 is provided on the adjustment plate 24. The light source bracket 251 is installed through the adjustment groove 241. The light source bracket 251 slides in the adjustment groove 241. The light source 25 is installed on the light source bracket 251. The adjustment groove 241 on the adjustment plate 24 is elongated or arc-shaped. When it is elongated, the adjustment groove 241 is arranged along the length of the adjustment plate 24. The light source bracket 251 is fixed in the adjustment groove 241 by fasteners. The width of the adjustment groove 241 matches the diameter of the fasteners.

[0022] The light source bracket 251 has a linear or arc-shaped movement path. By loosening the fasteners, the light source bracket 251 can be slid along the adjustment groove 241, which can change the distance between the light source and the detection box 13 to obtain optimal illumination intensity and uniform light source.

[0023] The camera 23 is mounted on the adjustment plate 24. Two cameras 23, two adjustment plates 24, two rotating plates 27, and two reversing mirrors 26 are configured, with the two cameras 23 arranged symmetrically. By setting up two symmetrical camera systems, and with their respective reversing mirrors 26, the same small box can be imaged simultaneously from two different angles, and two different small boxes 13 can be detected simultaneously, improving detection efficiency.

[0024] like Figure 8 As shown, the conveying mechanism 1 is a turntable conveying assembly, including a turntable 11 and a driving element 14. The turntable 11 is provided with a station 12 for placing small boxes 13, and the driving element 14 is provided below the turntable 11 for driving the turntable 11 to rotate.

[0025] The turntable conveyor assembly can employ intermittent motion, for example, controlled by a servo motor. Driven by the drive element 14, the turntable rotates by one station angle and then stops precisely, bringing a small box 13 to a stable stop directly below the vision imaging system 2.

[0026] like Figure 9 As shown, it also includes a rejection assembly, comprising a rejection bracket 31 and a rejection head 32. The rejection bracket 31 is fixed to the bottom of the turntable 11 by bolts, and a rejection hole is provided on the workstation 12. The rejection head 32 is connected to a rejection drive element for driving, which is a cylinder or an electric push rod. A rejection assembly is provided below each workstation 12.

[0027] Preferably, the rejection bracket 31 is provided with a guide groove, and the rejection head 32 is mounted in the guide groove by a slider and can reciprocate in the guide groove. This ensures the accuracy and stability of the movement trajectory.

[0028] The rejection bracket 31 is securely fixed to the bottom of the turntable 11 with bolts, forming an integral moving unit with the turntable 11. This ensures that the installation position of the rejection mechanism is absolutely fixed relative to the station 12 on the turntable and will not shift due to vibration or operation.

[0029] In one embodiment, the rejection bracket 31 is mounted on a fixed base below the turntable 11, keeping its position fixed, while the turntable 11 rotates with the station 12. When the station with the rejection hole moves directly above the fixed rejection component, the rejection head 32 then moves to perform rejection.

[0030] The end of the rejection head 32 is provided with an elastic buffer pad, which is made of silicone or rubber. The diameter of the rejection hole is larger than the maximum outer diameter of the rejection head 32, and the position of the rejection hole is aligned with the moving path of the rejection head 32.

[0031] Elastic cushioning pads made of silicone or rubber have good elasticity and toughness, and can absorb and disperse most of the impact energy at the moment of contact.

[0032] It also includes a position sensor 4, which is a photoelectric sensor. The transmitting end and receiving end of the photoelectric sensor are respectively installed on both sides of the turntable, and the detection beam of the photoelectric sensor is parallel to the rotation plane of the turntable.

[0033] The position sensor can accurately detect the moment when each workstation 12 arrives directly below the vision imaging system 2 and sends a signal to the control system, thereby triggering the camera 23 to take a picture and acquire an image. This ensures that each imaging is completed in the optimal position and in a stationary state, avoiding motion blur.

[0034] When the rejection assembly is fixed, after the vision system determines that a small box 13 is a defective product, the system needs to know when this defective product will move to the position of the rejection assembly. The position sensor continuously monitors the rotation of the turntable, accurately calculates the time when the defective product arrives at the fixed rejection assembly, and issues a command at the appropriate time to drive the rejection head 32 to move.

[0035] like Figure 6 and Figure 7 As shown, a mounting bracket 5 is provided at the bottom of the mounting post 22. The mounting bracket 5 extends to the back of the housing 21 and has a cable management hole 51. The cable management hole 51 provides a centralized and protected passage for cables, power lines, signal lines, and communication lines connecting various components inside the visual imaging system, such as cameras, light sources, and position sensors. The mounting bracket 5 can be fixed to other working devices, such as the overall housing of a conveying mechanism.

[0036] The light source 25 can be an LED lamp or a halogen lamp. LED lamps are suitable for high-precision detection, with stable brightness and low heat generation; halogen lamps are suitable for scenarios where the reflectivity of aluminum paper is required to be high.

[0037] It should be noted that the control system, camera, and light source in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0038] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
