[0002] Waste electrical appliances primarily include substandard products and their components from the production process, scrapped products and discarded parts from the repair process, and various electronic and electrical equipment and components that have lost their original functionality after use by consumers, or that retain their original functionality but need to be replaced and replaced. Electronic products contain a large amount of rare metals, valuable metals, and polymer materials. Recycling and disassembly can effectively extract and reuse these resources, extending their service life and reducing demand on natural resources.

[0003] After searching, the Chinese invention patent number CN218283142U discloses a disassembly device for recycling and processing waste electrical appliances;

[0004] Compared with the existing technology, this invention patent with Chinese patent number CN218283142U can drive the first extrusion block, the U-shaped moving plate and the rotating mechanism to move through a hydraulic cylinder, so that the first extrusion block and the second extrusion block can clamp the electrical appliance, and flip the electrical appliance under the action of the rotating mechanism, thereby improving the disassembly efficiency.

The capacity calculation unit receives the volume data sent by the part volume calculation unit and calculates the percentage occupancy or remaining space of the recycling box.

[0031] The present invention has the following beneficial effects:

[0032] 1. In the present invention, the height of the waste electrical appliances can be quickly and easily adjusted by raising and lowering the rotating plate to a position most suitable for workers to operate, thereby improving the efficiency of recycling and disassembly.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figures 1-8 As shown, the present invention proposes a disassembly device for recycling waste electrical appliances, comprising a workbench 1, a conveying device 2, and a cutting device 35 symmetrically fixed on the top of the workbench 1. An L-shaped frame 36 is installed on the top of the workbench 1, a square plate 37 is installed on the side of the workbench 1 away from the conveying device 2, and multiple sorting robots 3 are installed on the outer side of the conveying device 2. The L-shaped frame 36 is movably connected to the rotating plate 13 on the side close to the cutting device 35, and an adjustment component for the rotating plate 13 is provided on the L-shaped frame 36. The adjustment component is used to adjust the rotation The movable plate 13 is in position, and a plurality of telescopic rods 14 are installed on the top surface of the rotating plate 13. A plurality of tooth grooves 15 are opened on the outer side of the rotating plate 13. A side of the square plate 37 close to the cutting device 35 is slidably connected to the circular plate 23, and the inner side of the circular plate 23 is rotatably connected to a plurality of rotating rods 24. The upper part of the circular plate 23 is movably connected to a baffle 25 for protecting waste electrical appliances.

The outer side surface of the transmission device 2 is installed with a plurality of box bodies 5, and the upper part of the box body 5 is movably connected to a movable block 7;

[0047] The transmission device 2 and the sorting robot 3 are both equipped with an intelligent sorting system, which includes:

[0048] Image acquisition module 28, used to obtain images of disassembled parts;

[0049] The image preprocessing module 29 is used to perform preprocessing operations on the part image collected by the image acquisition module 28;

[0050] A feature extraction module 30 is used to extract key features from the part image processed by the image preprocessing module 29;

[0051] an intelligent recognition module 31 for identifying parts based on the extracted key features;

[0052] The automatic classification module 32 is used to automatically control the sorting robot 3 to sort parts according to the recognition results of the intelligent recognition module 31;

[0053] A capacity monitoring module 34 is used to monitor the capacity of the recycling box 4 in real time;

[0054] The user interface and interaction module 33 provides a user interface to display classification data and capacity data;

[0055] A support frame 9 is installed on one side of the L-shaped frame 36 close to the cutting device 35, and a third servo motor 27 is installed on the top of the support frame 9. The output shaft end of the third servo motor 27 extends to one end inside the support frame 9 and is installed with a first threaded rod 10, and the first threaded rod 10 is rotatably connected to the support frame 9. A first sliding block 11 is slidingly provided on the inner side of the support frame 9, and the first sliding block 11 is threadedly connected to the first threaded rod 10. A support plate 12 is installed on one end of the first sliding block 11 close to the rotating plate 13, and the rotating plate 13 is rotatably connected to the top of the support plate 12. A plurality of tooth grooves 15 are evenly distributed on the outer side of the rotating plate 13. An adjustment component is provided on the top of the first sliding block 11, and the adjustment component includes a worm gear 18 rotatably connected to the top of the first sliding block 11, and the worm gear 18 is meshed with the tooth groove 15. A first servo motor 16 is installed on the top of the first sliding block 11, and a worm 17 is installed on the end of the output shaft of the first servo motor 16, and the worm 17 is meshed with the worm wheel 18;

[0056] The recycling box 4 is movably connected to the box body 5, and a spring 6 is installed on the inner side of the box body 5. The top of the spring 6 is fixedly connected to the movable block 7. A sliding plate 8 is installed on the side of the movable block 7 away from the transmission device 2. A sliding groove 19 is provided on the side of the square plate 37 close to the cutting device 35. A second sliding block 20 is slidingly provided inside the sliding groove 19. A second servo motor 22 is installed on the top of the workbench 1. The output shaft end of the second servo motor 22 extends to one end inside the sliding groove 19 and is equipped with a second threaded rod 21, and the second threaded rod 21 is rotatably connected to the sliding groove 19. The second threaded rod 21 is threadedly connected to the second sliding block 20. The side of the second sliding block 20 away from the second threaded rod 21 is fixedly connected to the circular plate 23. The side of the baffle 25 away from the second threaded rod 21 is rotatably connected to the third threaded rod 26, and the circular plate 23 is threadedly connected to the third threaded rod 26.

[0057] When the second servo motor 22 is started, the second threaded rod 21 is driven by the second servo motor 22 to rotate. Since the second threaded rod 21 is threadedly connected to the second sliding block 20, the second sliding block 20 can be driven to move along the sliding groove 19 by the rotation of the second threaded rod 21, and the electrical appliance on the circular plate 23 is lifted up. When the circular plate 23 rises to be parallel to the rotating plate 13, the lifting is stopped. Then, the baffle 25 is driven to move by the force generated by the rotation of the third threaded rod 26 until the baffle 25 is parallel to the circular plate 23 and no longer protects the electrical appliance. Then the electrical appliance is moved and the rotating rod 24 is rotated to facilitate the movement of the electrical appliance. Then, the electrical appliance is moved to the rotating plate 13, which saves physical effort in carrying the electrical appliance and improves the safety of the recycling and disassembly process.

[0058] Since the rotating plate 13 is provided with a plurality of retractable tooth grooves 15, when the electrical appliance moves onto the rotating plate 13, the retractable tooth grooves 15 around the electrical appliance can limit the electrical appliance, ensuring that the electrical appliance will not move accidentally during the recycling and disassembly process, reducing the safety risks caused by the movement of the electrical appliance, and then the third servo motor 27 can be started, and the first threaded rod 10 can be driven to rotate by the third servo motor 27. Since the first threaded rod 10 is threadedly connected to the first sliding block 11, the first sliding block 11 can be driven to rise by the force generated by the rotation of the first threaded rod 10, so that the electrical appliance reaches the most suitable position for work. The operator uses the cutting device 35 to cut the operating position, thereby improving the efficiency of recycling and disassembly. During the recycling and disassembly process, the first servo motor 16 can be started, and the worm 17 can be driven to rotate by the first servo motor 16. Since the worm wheel 18 and the worm 17 are engaged with the tooth groove 15, when the worm 17 rotates, the rotating plate 13 can be driven to rotate through the worm wheel 18 and the tooth groove 15. The direction of the electrical appliance can be changed by rotating the rotating plate 13, which facilitates access to various parts of the electrical appliance and enhances the flexibility of operation. Then, the waste electrical appliance can be cut by the cutting device 35 and disassembled into recyclable metal parts and plastic parts.

[0059] Example 2

[0060] like Figures 1-8 As shown, based on the first embodiment, the feature extraction module 30 performs feature extraction through a convolutional neural network, and the feature extraction process is as follows:

[0061] Input layer: receives the preprocessed part image as input;

[0062] Convolutional layer: Performs convolution operations on the input part image. Each convolution kernel represents a specific feature detector. By stacking multiple convolutional layers, different levels of features from low-level to high-level can be extracted.

[0063] Activation function: The activation function maps the output of the convolutional layer to a new nonlinear range, enabling the model to learn more complex feature representations;

[0064] Pooling layer: downsamples the part image, max pooling selects the maximum value within each pooling window as the output, and average pooling calculates the average of all values ​​within the window;

[0065] Feature output: After processing through multiple convolutional layers, activation functions, and pooling layers, one or more feature vectors are output. The feature vectors contain key information extracted from the input image.

[0066] The intelligent recognition module 31 includes a recognition unit and a recognition result output unit. The recognition unit recognizes the part through a classification algorithm. The recognition result output unit outputs the recognition result of the part and passes the recognition result to the automatic classification module 32. The classification algorithm is SVW, which is in the form of:

[0067] f(x)=sign(ω·x+b)

[0068] Wherein x represents the eigenvector of the input sample, ω represents the normal vector of the hyperplane, b represents the intercept of the hyperplane, f(x) represents the predicted value of the sample, which is determined by the sign function sign(·), mapping the input value to +1 or -1, and is used for classification problems. The capacity monitoring module 34 includes a laser ranging unit, a part volume calculation unit and a capacity calculation unit. The laser ranging unit is responsible for emitting a laser beam to the top of the part in the recycling box 4 and receiving the reflected laser beam, and measuring the time from the emission to the reception of the laser beam, and converting the measured time data into distance data. The part volume calculation unit calculates the capacity or volume of the current part based on the distance data of the laser ranging unit and the known size of the recycling box 4. The capacity calculation unit receives the volume data sent by the part volume calculation unit and calculates the percentage occupancy or remaining space of the recycling box 4.

[0069] In this embodiment, after the parts of the electrical appliance are disassembled, the parts can be directly placed on the transmission device 2 and transmitted through the transmission device 2. At this time, the image of the parts on the transmission device 2 can be obtained through the image acquisition module 28, and then the image preprocessing module 29 performs denoising and contrast enhancement preprocessing operations on the image collected by the image acquisition module 28 to improve the image quality. The feature extraction module 30 extracts relevant features from the processed part image, the intelligent recognition module 31 recognizes the part image, and the automatic classification module 32 classifies the parts according to the recognition results. Then, the classification data is displayed on the sorting robot 3, and the classification information is transmitted to the sorting robot 3. The sorting machine Person 3 will clamp the corresponding parts into the recycling box 4 at the corresponding position, thereby realizing efficient automatic classification and recycling. This automation method can greatly improve the classification and recycling speed of metal parts and plastic parts of waste electrical appliances, while reducing human errors and improving the accuracy of classification and recycling. At the same time, the capacity of the recycling box 4 can be monitored by the capacity monitoring module 34, and then the relevant data can be displayed on the user interface and interaction module 33. When the parts in the recycling box 4 are full, the staff can be reminded to replace them. At this time, the sliding plate 8 can be pulled to retract the movable block 7 into the box body 5. At this time, the spring 6 contracts, and then the recycling box 4 can be separated from the box body 5, and the parts in the recycling box 4 can be transported to the designated location.

[0070] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
