[0030] See also Figure 1 , Figure 2 and Figure 3The intelligent self-adaptive multi-layer flexible material tray system 100 includes: a plurality of carrier lifting components 10, a plurality of tray conveying components 20, a plurality of push plate mechanism components 30 and a plurality of head components 40. Further, the intelligent self-adaptive multi-layer flexible material tray system 100 also includes: a housing 70 and an operating device 80.

[0031] Each carrier lifting assembly 10 is used to carry a basket assembly 50 , wherein the basket assembly 50 is used to accommodate a tray.

[0032] Each tray conveying assembly 20 is disposed on a first side of its corresponding basket assembly 50 .

[0033] Each push plate mechanism assembly 30 is arranged on the second side of its corresponding basket assembly 50, and is used to push the target pallet in the basket assembly 50 to the corresponding pallet conveying assembly 20; wherein, the pallet conveying assembly 20 is used to convey the target pallet to the material placement position, and the pallet conveying assembly 20 is configured to adjust the track width in the pallet conveying assembly according to the size of the target pallet to adapt to the target pallet.

[0034] Each head assembly 40 is used to absorb materials from the corresponding flexible vibration plate 60, and move to the material placement position to place the materials in the target pallet; wherein, after the materials are placed in the target pallet, the push plate unit in the pallet conveying assembly 20 pushes the target pallet into the basket assembly 50.

[0035] See also Figure 4 and Figure 5 The head assembly 40 is composed of a motor 45, a motor 43, a slide rail 47, a synchronous wheel 42, a synchronous belt 44, a visual component 41, and a suction nozzle 46.

The flexible vibration plate 60 vibrates the material, the visual component 41 (camera) detects the front of the material, and the head suction nozzle 46 sucks the material and puts it into the tray.

[0036] See also Figure 6 , Figure 7 and Figure 8 The carrier lifting assembly 10 is composed of a motor 11, a lead screw 14, a guide rail, a synchronous wheel 12, and a synchronous belt 13. When the basket assembly 50 is manually loaded, it is placed on the carrier lifting Z-axis station. At this time, the carrier lifting assembly 10 pushes the plate push mechanism assembly 30 to push the pallet into the pallet conveying assembly 20 and flows into the next station.

When the pallet flows into the conveying track formed by the synchronous wheel and the synchronous belt 25, the Z-axis lift 23 lifts the pallet, and the head assembly 40 takes the material and arranges the material on the plate. When the pallet is full, the Z-axis lift 23 lowers the pallet into the conveying track. The push plate unit 22 pushes the pallet into the basket assembly 50.

[0038] Exemplarily, the production process is as follows:

[0039] 1. Manually place the basket assembly 50 filled with empty pallets into the corresponding carrier lifting assembly 10.

[0040] 2. The carrier lifting assembly 10 docks with the plate pushing mechanism assembly 30 to push the pallet into the pallet conveying assembly 20 .

[0042] 4. The flexible vibration plate is loaded with materials. The camera detects the front and back of the materials, and the head assembly 40 sucks eight materials in turn and puts them on the tray.

[0043] 5. After the materials in the pallet are filled in sequence, the pallet conveying assembly 20 conveys the pallet to the basket assembly 50 on the carrier lifting assembly 10 .

[0044] 6. The push plate unit 22 of the tray conveying assembly 20 pushes the trays filled with materials into the basket assembly 50 in sequence. After the basket assembly 50 is full, it is taken away manually.

[0045] In some embodiments, the above-mentioned intelligent adaptive multi-layer flexible material tray system 100 further includes a first multispectral image acquisition component and a processing component. The first multispectral image acquisition component is used to acquire a multispectral image of a target pallet; wherein the multispectral image includes a visible light image, an infrared image, and an ultraviolet image. The processing component is coupled to the first multispectral image acquisition component, and is used to fuse the multispectral images, and identify the target pallet from the fused multispectral images, and control the pallet conveying component to adjust the track width in the pallet conveying component according to the identification result.

[0046] Among them, the processing component is also used to extract image features of visible light images, infrared images and ultraviolet images respectively, and fuse the image features to obtain multi-spectral fusion features, and use a low-rank metric model based on orthogonal learning to reduce the dimension and denoise the multi-spectral fusion features to obtain a low-rank feature representation, and identify the target pallet based on the low-rank feature representation.

[0047] The processing component is also used to compensate for the system error corresponding to the first multispectral image acquisition component according to a preset period.

[0048] Among them, the processing component is also used to perform multi-axis coordinated control of the motors in the carrier lifting component, the pallet conveying component, the push plate mechanism component and the head component.

[0049] That is, the intelligent adaptive multi-layer flexible material tray arrangement system 100 of the present application can realize adaptive tray processing, which is specifically realized by using a high-precision visual recognition system and an adaptive adjustment mechanism driven by a servo motor.

[0050] For example, multi-spectral vision fusion technology is used. In addition to visible light, infrared and ultraviolet spectra are added in this application to enhance the ability to recognize pallets of different materials and colors, reduce ambient light interference, and improve recognition robustness, especially for reflective pallets and transparent pallets.

[0051] The detailed scheme of multispectral vision fusion technology can adopt sensor fusion, feature fusion, adaptive multi-scale feature fusion, low-rank metric based on orthogonal learning, mixed loss function, and data enhancement technology.

[0052] Among them, sensor fusion is mainly reflected in the use of a multispectral camera (the first multispectral image acquisition component) to simultaneously collect visible light, infrared and ultraviolet images, and align these images to form a multispectral data set.

[0053] Among them, feature fusion is mainly reflected in the feature extraction stage, which extracts the features of visible light, infrared and ultraviolet images respectively, and then fuses these features. The fusion method can adopt channel splicing, weighted fusion or attention mechanism.

[0054] Among them, channel stitching can be reflected in directly stitching the feature maps of different spectra in the channel dimension as multi-spectral fusion features.

[0055] Among them, weighted fusion can be reflected in weighted fusion of feature maps according to the contribution of different spectra. For example, the infrared spectrum may have a higher weight at night or in low light conditions.

[0056] Among them, the attention mechanism can be reflected in using the attention mechanism to dynamically adjust the weights of different spectral features, thereby highlighting the features that are beneficial to recognition.

[0057] Among them, adaptive multi-scale feature fusion is mainly reflected in the fused multi-spectral features. The adaptive multi-scale feature fusion module is used to extract shallow features of different scales. This module can solve the recognition problem of pallets of different sizes and types, especially pallets with complex shapes or structures.

[0058] Among them, the low-rank metric based on orthogonal learning is mainly reflected in the use of a low-rank metric model based on orthogonal learning to reduce the dimension and denoise the fused multi-spectral features to obtain a low-rank feature representation. This step can improve the robustness of the model and reduce the impact of noise on the recognition results.

[0059] The hybrid loss function mainly uses the adaptive hybrid loss module to optimize the classification results and solve the problem of uneven distribution of pallet categories. It can also balance the learning capabilities of different categories and improve the classification accuracy of small categories through adaptive weights and multi-classification heads.

[0060] Among them, data enhancement is mainly reflected in the fact that since there are relatively few infrared and ultraviolet image data, data enhancement techniques such as rotation, scaling, translation, noise addition, etc. can be used to expand the training data set.

[0061] Data augmentation methods should be customized according to the characteristics of different spectra.

[0062] The algorithm flow is as follows:

[0063] Visible light images, infrared images and ultraviolet images are collected. Then multispectral image registration is performed to form a multispectral dataset. And the multispectral fusion features are extracted using an adaptive multiscale feature fusion module. And the features are reduced in dimension and denoised using a low-rank metric model of orthogonal learning. And the classification model is optimized using a mixed loss function. Finally, the pallet recognition result is output.

[0064] The technical effects of the above method are: improving recognition robustness, enabling more accurate pallet recognition, and having stronger anti-interference ability.

[0065] Improving recognition robustness is mainly reflected in the fact that multi-spectral visual fusion can effectively reduce the interference of ambient light and improve the robustness of the recognition system under different lighting conditions. The addition of infrared and ultraviolet spectra can enhance the system's recognition ability for different materials and color pallets.

[0066] More accurate pallet identification is mainly reflected in the fact that infrared spectroscopy can distinguish pallets with different thermal characteristics, while ultraviolet spectroscopy can identify pallets with special surface coatings, thereby improving the recognition accuracy of complex pallets. In particular, infrared and ultraviolet spectroscopy can help solve the problem of identifying reflective and transparent pallets.

[0067] Stronger anti-interference ability is mainly reflected in the low-rank metric and mixed loss function through data enhancement, orthogonal learning, which can further improve the system's anti-noise and interference ability.

[0068] Furthermore, the processing components can use self-calibration and compensation algorithms. For example, a self-calibration algorithm based on deep learning can be developed to regularly calibrate the visual system and automatically compensate for system errors caused by temperature changes, vibrations, etc., to ensure long-term stability and high accuracy.

[0069] Furthermore, the processing component can also upgrade the servo motor-driven linear adjustment to multi-axis coordinated adjustment, achieving fine adjustment of the pallet in the horizontal and vertical directions, enhancing adaptability to complex pallet shapes, and making the adjustment process smoother and more stable.

[0070] In some embodiments, the material strength of the carrier lifting assembly 10 is greater than a threshold value, and the material weight is less than a threshold value, wherein the carrier lifting assembly 10 is used to dynamically adjust the operating speed according to the weight of the basket assembly; and each carrier lifting assembly 10 is configured with an independent control unit.

[0072] For example, a lightweight modular Z-axis mechanism is used. This is mainly reflected in the use of high-strength lightweight materials and the optimization of the Z-axis structural design to reduce inertia, improve movement speed and response, and reduce energy consumption.

[0073] The use of a distributed multi-core control system is mainly reflected in the upgrading of the synchronization control algorithm to a distributed multi-core control system. Each Z-axis mechanism has an independent control unit, which can be processed in parallel, reducing the computing pressure of the main control unit, achieving more sophisticated collaborative control, and improving the real-time and reliability of the overall operation.

[0074] The use of dynamic load balancing algorithm is mainly reflected in the development of dynamic load balancing algorithm, which dynamically adjusts the running speed and acceleration of the Z axis according to the weight and quantity of materials on each layer of pallet, reduces equipment vibration, improves overall stability, and reduces equipment loss.

[0076] In some embodiments, the intelligent adaptive multi-layer flexible material tray system 100 of the present application can realize the grasping of flexible materials, which is specifically realized by using a flexible material suction nozzle, pressure feedback control, material posture recognition based on deep learning, and a force feedback sensor.

[0077] For example, the use of adaptive multi-cavity vacuum nozzle is mainly reflected in the design of flexible material nozzle into multiple independently controlled vacuum chambers. Each vacuum chamber can independently adjust the vacuum degree according to the shape and size of the material, thereby improving the flexibility and stability of grasping, especially for irregular and fragile materials.

[0093] Among them, data processing and fusion are mainly reflected in data registration, multimodal data fusion, and data enhancement.

[0094] Among them, data registration is mainly reflected in the registration of multispectral images and multimodal tactile sensor data to achieve synchronization in time and space.

[0095] Among them, multimodal data fusion is mainly reflected in early fusion, late fusion and dynamic fusion.

[0096] Among them, early fusion is mainly reflected in the fusion of multimodal data before feature extraction, such as channel splicing or weighted summation.

[0097] Among them, late fusion is mainly reflected in the extraction of multimodal features separately, and then the fusion is carried out using attention mechanism, gating network or decision fusion method.

[0098] Among them, dynamic fusion is mainly reflected in the dynamic adjustment of the weights of different modal information according to different tasks and scenarios.

[0099] Among them, data enhancement is mainly reflected in the use of data enhancement methods to increase the diversity of training data and improve the generalization ability of the model.

[0100] Among them, system integration is mainly reflected in hardware integration and software integration.

[0101] Hardware integration mainly consists of integrating a multispectral camera and a multimodal tactile sensing array into a compact sensing unit.

[0102] Software integration is mainly reflected in the development of a unified software framework to achieve the collection, processing, analysis, fusion and visualization of multimodal data.

[0103] The technical effects of the above method mainly include enhanced object recognition capabilities, safer grasping operations, higher grasping success rates, wider application scenarios, and the ability to recognize and safely grasp special materials.

[0104] The enhanced object recognition capability is mainly reflected in the improvement of the recognition accuracy of the object material, temperature and surface texture by fusing multimodal information. For example, it can distinguish between metal and plastic, high-temperature objects and normal-temperature objects, and surfaces with different textures.

[0105] Safer grasping operations mainly rely on the use of multimodal tactile feedback to achieve safe grasping of fragile objects, high-temperature objects, or objects with special surface textures.

[0106] The higher grasping success rate is mainly reflected in the fact that more comprehensive perception and control capabilities can improve the grasping success rate in complex scenarios.

[0107] The wider application scenarios are mainly reflected in the fact that the system can be applied to a wider range of fields, such as intelligent manufacturing, medical robots, home service robots and wearable electronic devices.

[0108] The recognition and safe grasping of special materials is mainly reflected in the fact that by combining multimodal tactile feedback, special materials can be recognized, such as high-temperature objects, fragile objects or objects with special surface textures, to ensure safe grasping.

[0114] Multi-task prediction mainly involves using deep learning models to identify material postures and simultaneously predict contact positions, force magnitudes, temperatures, surface textures, and material categories.

[0115] The output is mainly reflected in the output material's posture information, force feedback information, temperature information, surface texture information and material category.

[0116] In some embodiments, gesture recognition based on 3D point clouds may be used, which may specifically upgrade gesture recognition based on 2D images to gesture recognition based on 3D point clouds, so as to more accurately obtain the three-dimensional information of the material, reduce the recognition errors caused by factors such as lighting changes and occlusion, and make the grasping gesture more accurate.

[0117] 3D point cloud posture recognition mainly includes 3D Gaussian sputtering initialization, adaptive density control, posture estimation, etc.
