Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a conveying detection device and method for processing aluminum alloy plates. Background Art

[0002] With the rapid development of the aerospace, automobile manufacturing and electronics industries, the demand for high-precision aluminum alloy materials is increasing. Aviation-grade aluminum alloys are widely used in aircraft skins, aviation parts, automobile bodies, and electronic equipment housings due to their excellent properties such as high strength, light weight, and corrosion resistance. The manufacturing and processing requirements for this type of aluminum alloy sheet are extremely strict, especially in terms of surface quality and dimensional accuracy. Any tiny flaws or defects may affect its final performance. Therefore, in order to ensure product quality, aluminum alloy sheets must be precisely tested during the production process to meet the industry's high standards for materials.

[0003] However, the existing technology usually uses visual inspection to inspect the quality of aluminum alloy plates. This traditional inspection method often relies on two sets of cameras to shoot and analyze the surface of the plate. However, due to the high reflective properties of the aluminum alloy surface, light is easily reflected to the camera during the inspection process, resulting in reflective spots in the image, which in turn interferes with the inspection accuracy. In addition, the camera shooting angle is relatively fixed and single, making it difficult to fully cover all surface areas of the aluminum alloy plate. In particular, for the inspection of tiny dents or small scratches on the surface, the existing technology has the problem of false detection and missed detection, and the accuracy of the inspection results is low and the error is large.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0056] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0057] Embodiment 1:

[0058] Combination Figures 1 to 8 As shown, an embodiment of the present invention provides a conveying and detecting device for processing aluminum alloy plates, including a conveying and loading mechanism 100 and a unloading mechanism 400, and a detecting mechanism 200 disposed between the conveying and loading mechanism 100 and the unloading mechanism 400, and a clamping mechanism 300 for transporting aluminum alloy plates is disposed on one side of the detecting mechanism 200. The conveying and detecting device for processing aluminum alloy plates can realize the automated process from loading to detection and then to unloading of aluminum alloy plates by arranging the conveying and loading mechanism 100 and the unloading mechanism 400, thereby improving the efficiency of the production line. The clamping mechanism 300 disposed on one side of the detecting mechanism 200 can stably and accurately convey the aluminum alloy plates from loading to the detecting platform 210.

[0059] The detection mechanism 200 includes a detection platform 210 for placing an aluminum alloy plate, a first imaging component 220 is arranged on one side of the detection platform 210, and the first imaging component 220 includes two first cameras 221 arranged in parallel in a horizontal direction, and a first planar light source plate 222 is arranged opposite to the first camera 221. Through the parallel dual-camera design, the system can simultaneously collect images of the side of the plate from multiple angles, thereby effectively avoiding the problem of incomplete image information caused by shooting at a single angle, and improving the comprehensiveness and accuracy of the detection.

[0060] A second imaging component 230 is disposed above the detection platform 210. The second imaging component 230 includes a second camera 231 disposed vertically downward, and an annular light source plate 232 is disposed below the second camera 231. The annular light source plate 232 is equipped to provide 360-degree uniform illumination for the upper surface of the plate, avoiding detection blind spots or reflection interference caused by uneven light sources, and ensuring accurate detection of upper surface defects and dimensions. This design is particularly suitable for detection scenarios of aluminum alloy plates with strong surface reflections.

[0061] The detection platform 210 is provided with a detection hole 211, and a third imaging component 240 is arranged below the detection platform 210. The third imaging component 240 includes a second plane light source plate 241 arranged below the detection hole 211, and a surface camera 242 is arranged on one side of the second plane light source plate 241; wherein, the second plane light source plate 241 is provided with a first linear module 243 for driving its movement, the surface camera 242 is rotatably connected to the camera bracket 244, and one side of the surface camera 242 is connected to an angle adjustment member 245.

[0062] It should be noted that since the light brightness below the detection platform 210 is relatively low, it is less affected by ambient light. Therefore, it is necessary to consider whether the shooting angle of the tilted surface camera 242 will produce a reflective area when shooting. Therefore, the light and shadow effects are balanced by using a second planar light source panel 241 and a surface camera 242 that can be moved and adjusted.

[0063] Through this multi-level, multi-angle visual inspection design, the entire device can achieve all-round inspection of aluminum alloy plates, avoiding missed detection and false detection caused by problems such as surface reflection and single angle in traditional inspection, improving the efficiency and accuracy of inspection, and is particularly suitable for aluminum alloy plate inspection scenarios with high precision requirements.

[0064] The working principle of the present invention is as follows: when working, starting from the conveying and loading mechanism 100, the aluminum alloy plate is conveyed to the detection mechanism 200, and the clamping mechanism 300 transfers the aluminum alloy plate to the detection platform 210, and the two parallel first cameras 221 cooperate with the first plane light source plate 222 facing it to shoot the side image of the plate; at the same time, the second camera 231 of the second imaging component 230 shoots the front of the plate vertically downward from the top, and cooperates with the annular light source plate 232 to achieve comprehensive surface detection; in addition, the second plane light source plate 241 supplies light to the lower surface of the aluminum alloy plate through the detection hole 211, and the surface camera 242 shoots and images the bottom surface of the plate, and the second plane light source plate 241 is driven by the first linear module 243 to achieve its position at different positions. Move, thereby ensuring that the all-round light source evenly illuminates the plate, and the angle of the surface camera 242 is flexibly adjusted through the angle adjustment member 245 to obtain the best detection angle; the device realizes all-round precision detection of aluminum alloy plates through multiple groups of cameras and multi-angle light source layout, the first camera 221 and the flat light source plate are arranged horizontally, and the annular light source corresponding to the second camera 231 forms diffuse light, which reduces the formation of high-intensity light and reduces the interference of ambient light sources, effectively avoiding detection interference caused by surface reflection, and combined with the adjustable third imaging component 240 to realize comprehensive detection of the bottom surface of the aluminum alloy plate, the flexibility of the overall device and the multi-angle detection design improve the accuracy and coverage of detection, and is suitable for aluminum alloy plate detection with high precision requirements.

[0065] In this embodiment, it is specifically described that the conveying and loading mechanism 100 includes two side plates 110 arranged at intervals, a chain assembly 120 is arranged between the two side plates 110, each link of the chain assembly 120 is connected to a chain plate 121, and a first driving motor 130 is arranged on one side of the chain assembly 120, and the first driving motor 130 is used to drive the chain assembly 120 to rotate.

[0066] It should be noted that each link of the chain assembly 120 is connected to a chain plate 121, and the surface of the entire conveying mechanism is composed of continuous chain plates 121, which can better support and convey the aluminum alloy plate and prevent the plate from vibrating or tilting during the conveying process. The first drive motor 130 is responsible for driving the rotation of the chain assembly 120, so that the aluminum alloy plate can move smoothly along the conveying line. This chain drive design is suitable for large-scale conveying of aluminum alloy plates on industrial assembly lines, providing higher transmission efficiency and durability.

[0067] In the present embodiment, it is further explained that a protective plate 140 is arranged above the side panel 110, and the protective plate 140 is installed on the side panel 110 through a connecting assembly 150; the connecting assembly 150 includes a first connecting plate 151 connected to the side panel 110, and a first support rod 152 is arranged on the first connecting plate 151 along the vertical direction, and a connecting hole 153 is provided at a preset position of the first support rod 152, and a second support rod 154 is transversely arranged through the connecting hole 153, and the second support rod 154 is movably connected to the connecting hole 153; an adjustment hole is provided at the upper end of the first support rod 152, and a locking piece 155 is threadedly connected to the adjusting hole, and one end of the locking piece 155 extends into the connecting hole 153 and abuts against the second support rod 154.

[0068] It should be noted that the structural design of the connection assembly 150 is relatively flexible, especially in the part where the second support rod 154 is movably connected through the connection hole 153, so that the height and position of the protective plate 140 can be adjusted as needed, which is convenient for flexible setting in different production environments. At the same time, the design of the adjustment hole and the locking member 155 on the first support rod 152 makes it possible to fix or adjust the position of the second support rod 154 by tightening or loosening the locking member 155, thereby achieving stability and flexible adjustment of the protective plate 140.

[0069] In this embodiment, the clamping mechanism 300 includes a first linear guide rail 310 arranged along the conveying direction of the conveying and feeding mechanism 100, and two groups of clamping jaw assemblies 320 are slidably connected to the first linear guide rail 310; the clamping jaw assembly 320 includes a main body plate 321, and the main body plate 321 is connected to a clamping jaw body 322 for clamping the workpiece.

[0070] When working, the two sides of the aluminum alloy plate are clamped by the clamping bodies 322 of the two sets of clamping jaw assemblies 320, and the clamping mechanism 300 allows the clamping jaw assemblies 320 to slide along the conveying direction through the first linear guide rail 310 provided on the conveying and feeding mechanism 100. This design allows the clamping mechanism 300 to flexibly adjust the position of the clamping jaws according to the position of the plate, ensuring accurate grasping and positioning of the aluminum alloy plate.

[0071] In this embodiment, a sliding groove is provided at one end of the main plate 321, and the first clamp block 323 and the second clamp block 324 are slidably connected in the sliding groove, and a connecting groove 325 is provided on a wall surface where the first clamp block 323 and the second clamp block 324 are close to each other, and a toothed portion 326 is provided on a wall surface where the two connecting grooves 325 are away from each other, and a connecting gear 327 is provided between the two connecting grooves 325, and the connecting gear 327 is meshed and connected with the toothed portions 326 of the first clamp block 323 and the second clamp block 324, respectively; wherein the first clamp block 323 is connected to a pushing cylinder 328, and the pushing cylinder 328 is used to push the first clamp block 323 to move linearly relative to the second clamp block 324.

[0072] It should be noted that two clamping blocks that move relative to each other are provided, namely, the first clamping block 323 and the second clamping block 324. The two clamping blocks mesh with each other through the connecting gear 327 and the toothed portion 326 thereon, ensuring that the two clamping blocks can move synchronously. The design of the connecting gear 327 ensures that the two clamping blocks always move in parallel, and the plate will not be damaged due to uneven force. The first clamping block 323 is driven by the push cylinder 328 to push the first clamping block 323 to move linearly relative to the second clamping block 324, thereby achieving clamping or releasing of the plate. The entire design enables the clamping mechanism to achieve stable and reliable clamping, and has the ability to respond quickly.

[0073] In this embodiment, it is specifically described that the first imaging component 220 includes a second linear guide rail 223, and two groups of base components 224 are slidably connected to the second linear guide rail 223, and the two first cameras 221 are respectively arranged on the corresponding base components 224; a second driving member 225 is arranged on one side of the second linear guide rail 223, and a screw rod 226 is arranged at the driving end of the second driving member 225, and the screw rod 226 is provided with a positive thread portion and a negative thread portion, and the two groups of base components 224 are respectively threadedly connected to the positive thread portion and the negative thread portion, and the second driving member 225 operates to drive the two first cameras 221 to move toward each other.

[0074] It should be noted that when the second driving member 225 is running, the screw drives the base assembly 224 to move toward each other. This design enables the two cameras to automatically adjust the distance as needed to adapt to aluminum alloy plates of different widths, thereby achieving more flexible and efficient side image acquisition. This precise design of moving toward each other effectively improves the detection accuracy of the system, especially when processing plates with large width variations.

[0075] In this embodiment, the second imaging component 230 includes a mounting plate 233, the second camera 231 is arranged on the mounting plate 233, the lower end surface of the mounting plate 233 is provided with a first mounting ring 234, and a second mounting ring 235 is provided below the first mounting ring 234. The diameter of the first mounting ring 234 is smaller than the diameter of the second mounting ring 235. The first mounting ring 234 and the second mounting ring 235 are connected by a conical panel 236, and the lower end surface of the conical panel 236 is provided with a light-absorbing coating 237; wherein, the lower end surface of the first mounting ring 234 is provided with a photosensitive element, and the annular light source plate 232 is provided on the second mounting ring 235.

[0076] The purpose of this design is to reduce the interference of light reflection when the camera is shooting, and to improve the contrast and clarity of the image.

[0077] Embodiment 2:

[0078] The present invention further provides a conveying detection method for processing aluminum alloy plates, which is implemented by using the conveying detection device for processing aluminum alloy plates as in the first embodiment. The conveying detection method comprises:

[0079] S1 , the conveying and loading mechanism 100 conveys the aluminum alloy plate to a preset position, and fixes the aluminum alloy plate on the detection platform 210 of the detection mechanism 200 through the clamping mechanism 300 .

[0080] S2, capturing a first image of the side surface of the plate by using two first cameras 221 arranged in parallel in a horizontal direction and a first planar light source plate 222 facing the first camera;

[0081] The first planar light source plate 222 provides uniform illumination to avoid image distortion caused by uneven light or reflection interference. The parallel setting of the dual cameras increases the coverage of the side image, ensuring that all kinds of detailed features on the side of the plate can be fully captured. The purpose of this step is to detect possible minor defects such as scratches and dents on the side through the side image.

[0082] S3, using the second camera 231 of the second imaging component 230 to shoot the front side of the plate downwards, combined with the annular light source plate 232, to shoot a second image of the upper surface of the plate; wherein the intelligent light source adjustment system dynamically adjusts the brightness of the annular light source plate 232 based on the reflection feedback from the second image.

[0083] S4, through the detection hole 211, the second plane light source plate 241 of the third imaging component 240 provides a bottom light source, and the surface camera 242 captures a third image of the upper surface of the plate; wherein the intelligent light source adjustment system drives the first linear module 243 to operate based on the reflection feedback of the third image to adjust the position of the second plane light source plate 241, and adjusts the shooting angle of the surface camera 242 through the angle adjustment member 245.

[0084] S5, integrating the first image, the second image and the third image, performing image processing and analysis, and identifying surface quality defects of the plate.

[0085] It should be noted that the system can conduct comprehensive inspections on the sides, top and bottom of the plate to identify surface defects, scratches, dents and other potential quality issues. Through multi-view and multi-angle image fusion analysis, the inspection results are more comprehensive and accurate to meet the quality control needs of high-precision aluminum alloy plates.

[0086] In this embodiment, the intelligent light source adjustment system dynamically adjusts the brightness of the annular light source plate 232 based on the reflection of the second image feedback, specifically including:

[0087] S301, detecting the brightness distribution in the second image through an image processing module, identifying whether there is an overexposed area caused by a high reflective area on the surface of the aluminum alloy plate, so as to obtain a reflective recognition result, and identifying the size and intensity of the reflective area in the image;

[0088] S302, determining, according to the reflection recognition result, a reflection area whose brightness needs to be reduced and a dark area whose brightness needs to be increased, so as to generate a light source adjustment strategy;

[0089] S303, dividing the annular light source plate 232 into a plurality of independently controllable areas, and controlling the brightness of each independent area through a circuit;

[0090] S304, dynamically adjusting the brightness of each independent area according to the light source adjustment strategy, reducing the light intensity of the reflective area, and increasing the light intensity of the dark area, so as to achieve uniform image brightness.

[0091] In this embodiment, the intelligent light source adjustment system drives the first linear module 243 to operate based on the reflection of the third image feedback to adjust the position of the second planar light source plate 241, and adjusts the shooting angle of the area camera 242 through the angle adjustment member 245, specifically including:

[0092] S401, the intelligent light source adjustment system analyzes the acquired third image in real time, identifies the reflective area and the part with uneven light in the third image, and generates a reflective detection signal; the signal is used to describe the specific reflective area and reflective intensity of the bottom surface of the plate.

[0093] S402, based on the reflection detection signal, the intelligent light source adjustment system calculates the optimal adjustment direction and position of the illumination angle of the second planar light source plate 241, and generates a light source position adjustment signal and an angle adjustment signal; the system generates a corresponding light source position adjustment signal based on the geometric shape of the plate, the light reflection angle and the required uniform illumination, and transmits it to the control unit of the first linear module 243.

[0094] S403, after receiving the light source position adjustment signal, the first linear module 243 drives the second planar light source plate 241 to move along a preset track to change the irradiation angle or distance of the light source; by adjusting the position of the light source plate, the system ensures that the light can irradiate the bottom surface of the aluminum alloy plate at the optimal angle, thereby reducing reflection interference and improving image clarity.

[0095] S404, the intelligent light source adjustment system determines the best shooting angle of the area camera 242 by analyzing the position of the reflective area in the third image, and transmits an angle adjustment signal to the control unit of the angle adjustment member 245 if the best shooting angle of the area camera 242 is within the reflective area;

[0096] S405, after receiving the angle adjustment signal, the angle adjustment member 245 adjusts the shooting angle of the surface camera 242 in real time. By adjusting the pitch or rotation angle of the surface camera 242, the reflective area is avoided to ensure that the surface camera 242 can capture a complete image of the bottom surface of the plate from the best angle. This dynamic adjustment process is coordinated with the position adjustment of the light source board to ensure that the captured image is free of reflection interference, and the clarity and detail presentation meet the expected standards.
