The aluminum frame is sealed and connected to the upper glass cover and the lower base plate by sealant, and the junction box is positioned on the upper glass cover by sealant.
[0003] When a photovoltaic module is damaged or needs to be repaired or recycled, in order to avoid the impact of arbitrary treatment on the environment, the frame and junction box of the photovoltaic module need to be removed. The existing method of removing the junction box is to first pre-treat the sealant between the junction box and the upper glass cover to make it soft and easy to remove, and then manually force the junction box to remove it. This type of removal method is inefficient.

[0039] Embodiment 1:
[0040] Example 1 Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a photovoltaic junction box disassembly device includes a walking mechanism 1, a disassembly mechanism 2, a support mechanism 3, a collection device and a control device, wherein the control device includes a controller and a positioning identification module;
[0041] The walking mechanism 1 is electrically connected to the controller. In the present embodiment, the walking mechanism 1 includes an X-axis moving unit and a Y-axis moving unit. The X-axis moving unit includes a bracket 101, a screw 102, and a screw motor 103; the screw motor 103 is connected to the screw 102, and the screw motor 103 and the screw 102 are both installed on the bracket 101; the Y-axis moving unit includes a bracket 2 104 and a transmission unit 105, and the transmission unit 105 is installed on the bracket 2 104. In the present embodiment, the bracket 2 104 is fixed on the bottom plate of the recycling and processing transfer vehicle or on the ground of the recycling and processing workshop. The transmission unit 105 includes a conveyor belt and a motor for driving the conveyor belt to move. The transmission unit 105 is located on the bracket 2 104, so that the photovoltaic module can be placed on the transmission unit 105 to achieve Y-axis movement.
[0042] Bracket 101 includes two fixed columns and a cross beam, the cross beam is fixed on the top of the fixed columns, and relative mounting holes are opened on the fixed columns. The screw rod 102 is fixed on the bracket 101 through the mounting holes. One end of the screw motor 103 is connected to the screw rod 102 and fixed on the fixed column. In this embodiment, the screw rod 102 adopts a ball screw rod 102, and a moving block capable of linear motion is provided on the ball screw rod 102.
[0043] The splitting mechanism 2 includes a connecting part 201 and a splitting part 202, which are integrally formed. The connecting part 201 is connected to the moving block on the screw rod 102, so that the connecting part 201 and the splitting part 202 can make a linear motion with the rotation of the screw rod 102. The splitting part 202 is a scraper in this embodiment. The controller first controls the Y-axis moving unit in the walking mechanism 1 to transfer the photovoltaic component to the specified position, and then controls the X-axis moving unit to control the movement of the splitting mechanism 2. Under the action of the screw rod 102 of the X-axis moving unit, the scraper removes the junction box on the photovoltaic component.
[0044] In this embodiment, the splitting part 202 includes a cutting unit 2021 and a buffer unit 2022. The cutting unit 2021 is tilted as a whole, one end of the cutting unit 2021 is blade-shaped, and the other end is integrally formed with the buffer unit 2022. The cutting unit 2021 has an inclination angle of 9°-11°, preferably 10° in this embodiment. The buffer unit 2022 is an inwardly curved surface, and the buffer unit 2022 is integrally formed with the connecting part 201. During use, the blade of the cutting unit 2021 is firstly The sharp edge splits the sealant at the connection between the junction box and the photovoltaic module. As the cutting unit 2021 is advanced, the inclined surface pushes the separated part of the junction box upward, so that the junction box can be disassembled more easily. When the cutting process reaches the buffer unit 2022, the curved surface of the buffer unit 2022 abuts against the junction box, which can give the junction box an oblique upward thrust. Compared with the planar buffer unit 2022, the thrust given to the junction box increases slowly. Therefore, the removal of the junction box will not cause a sudden change in force, thereby avoiding damage to the junction box during the removal process.
[0045] At the same time, in order to control the distance between the photovoltaic module and the splitting mechanism 2 to ensure a good splitting effect, a support mechanism 3 is also included, and a baffle is also arranged on the conveying unit 105, and the baffle can be controlled by a motor; the support mechanism 3 includes an upper hydraulic unit 301, a lower hydraulic unit 302 and a bracket three 303, and the upper hydraulic unit 301 is installed on the bracket three 303; the upper hydraulic unit 301 and the lower hydraulic unit 302 are electrically connected to the controller, and under the action of the controller, the photovoltaic module is transported on the conveying unit 105, and the photovoltaic module will be blocked by the baffle after reaching the position of the baffle. At this time, the controller controls the lower hydraulic unit 302 to lift the photovoltaic module and controls the upper hydraulic unit 301 to press down, so that the photovoltaic module is clamped and fixed. The distance between the photovoltaic module and the scraper in the splitting mechanism 2 can be achieved through the support mechanism 3. In the specific implementation process, the scraper fits the surface of the photovoltaic module so that the scraper can scrape off the junction box connected to the photovoltaic module by sealant.
[0046] The acquisition device includes a camera unit, which is electrically connected to a controller. The controller can control the camera unit to acquire image data of the photovoltaic component and transmit the image data to the positioning and identification module. In this embodiment, the acquisition device also includes a light source module. In this application, the light source module adopts a ring light, which is located at the upper part of the bracket 101 and is used to achieve the lighting function. The camera unit is also located at the upper part of the bracket 101.
[0047] The positioning and identification module is connected to the controller. Specifically, a network model is constructed in the positioning and identification module. The positioning and identification module receives the collected data transmitted by the collection device, inputs the collected data into the network model, outputs the junction box positioning data, and transmits it back to the controller. The controller controls the walking mechanism 1 to perform the action and controls the driving mechanism to drive the shearing mechanism to perform the shearing action according to the transmitted junction box positioning data.
[0048] In this embodiment, the positioning and identification module includes a data acquisition unit, a model building and training unit, a model processing unit and a data processing unit. Specifically, the data acquisition unit is used to obtain training sample data, junction box annotation data and junction box actual data. The training sample data represents the training samples used to train the network model for the location identification of the junction box. The source of the training sample can be obtained from the Internet or input by the user. The role of the training sample can make the identification of the network model targeted.
[0049] The model building and training unit is used to build a network model. In this embodiment, the network model adopts a YOLOv8 model. The model building and training unit is also used to receive training sample data and junction box annotation data, preprocess the training sample data, and combine the preprocessing result with the junction box annotation data to input the network model for training;
[0050] Specifically, the training sample data is preprocessed including rigid body transformation, random cropping, brightness processing and noise addition. The preprocessed training sample data is input into the YOLOv8 model, which can make the model have stronger generalization ability. Finally, normalization processing is performed to make the training of the model more convergent. In this embodiment, the junction box annotation data includes the size data of the junction box, the image data of the junction box and the positioning information of the junction box on the photovoltaic module.
[0051] The preprocessed training sample data and the junction box annotation data are then combined into a dataloder and input into the YOLOv8 model for training. The YOLOv8 model first extracts features through the backbone network. During this period, the C2f module is used to obtain rich gradient flow information while ensuring the lightweight of the network. The selected feature map is put into the detection head to locate the junction boxes of different sizes, so as to achieve the purpose of training the YOLOv8 model.
[0052] After the YOLOv8 model training is completed, the model processing unit is used to perform a channel pruning operation on the trained model, and the unpruned model is used as a teacher model to restore the accuracy of the pruned model through the knowledge distillation operation; in this embodiment, the model processing unit performs a channel pruning operation on the trained model specifically as follows:
[0053] Construct calculation formula 1, using the BN layer of the network model The parameters are used as scaling factors for network model pruning, and L1 regularization is introduced into the scaling factors for sparse training to generate calculation results;
[0054] A compression ratio is preset, for example, 5%, the scaling factors are sorted, and the channels where the scaling factors after the preset compression ratio are located are found and deleted;
[0055] The calculation formula 1 is specifically:
[0056]
[0057] in, represents the loss function after the introduction of L1 regularization, Represents the loss function of the normal training of the original network model, represents the regularization coefficient, represents the sum of the scaling factors of all channels. In this embodiment, calculation formula 1 is a loss function.
[0058] In the model processing unit, the unpruned model is used as the teacher model through the knowledge distillation operation to restore the accuracy of the pruned model. Specifically, calculation formula 2 is constructed to introduce the distillation temperature T in the softmax multi-classification layer of the network layer of the YOLOv8 model, as shown below:
[0059]
[0060] in, represents the output label probability distribution, , Represents the output label, T represents the distillation temperature, and the higher T is, the more information is obtained.
[0061] In the prior art, with the development of network models, the width and depth of network models continue to grow, which makes its memory usage, power consumption and calculation times increase sharply. Therefore, the processing of network models has been well developed, such as sparsification, channel pruning, etc. Among them, channel pruning is not related to the parameter accuracy of the model, and does not rely on proprietary hardware structure, so as to achieve better compression and acceleration. However, in the process of channel pruning, although the pruned part of the data has little significance, it is not completely redundant. Therefore, only channel pruning will cause the accuracy of the network model to decrease. For this reason, the present application also uses knowledge distillation operation to improve the accuracy of the network model after channel pruning, thereby improving the accuracy of positioning and recognition of the present application.
[0062] In specific implementation, after the photovoltaic component is fixed in place, it is illuminated by the light source module and photos are taken by the camera unit. When shooting, rulers are placed on both sides of the photo recognition area as reference objects. When taking pictures, the panel, junction box and ruler of the photovoltaic component are photographed together. The controller transmits the taken photos to the YOLOv8 model for inference to obtain the positioning information of the junction box.
[0063] The specific implementation process is as follows: the controller controls the conveying unit 105 to convey the photovoltaic components, and the acquisition device collects images. When a photovoltaic junction box appears in the image, it is identified and located through the positioning and recognition module. The controller controls the conveying unit 105 to convey the photovoltaic components to the bottom of the X-axis moving unit according to the positioning information. The controller then controls the splitting mechanism 2 to shovel the junction box on the photovoltaic component to complete the splitting of the photovoltaic junction box.
[0064] Embodiment 2:
[0065] like Figure 5 and Figure 6 As shown, the difference between the second embodiment and the first embodiment is that it further includes a driving mechanism, and the driving mechanism adopts an electric push rod 207.
[0066] In addition, the walking mechanism 1 includes an X-axis moving unit and a Y-axis moving unit, the X-axis moving unit includes a bracket 101 and a slide rail 106, the slide rail 106 is installed above the bracket 101, the Y-axis moving unit includes a bracket 204 and a transmission unit 105, and the transmission unit 105 is installed on the bracket 2 104; the splitting mechanism 2 includes a cutter frame 203, a left cutter 204 and a right cutter 205, the cutter frame 203 includes a fixed block 2031 and a sleeve 2032, the top of the fixed block 2031 is connected to the slide rail 106, a through hole is opened below the fixed block 2031, the sleeve 2032 is hollow inside and fixed on one side of the through hole, the electric push rod 207 is installed on the fixed block 2031 and is located on the other side of the sleeve 2032, and the push rod of the electric push rod 207 is located in the through hole, the left cutter 204 is installed on the sleeve 2032, and the right cutter 205 is installed on the push rod of the electric push rod 207.
[0067] The specific implementation process is as follows: by connecting the cutter frame 203 with the slide rail 106, the splitting mechanism 2 can move in the X direction. In the cutter frame 203 of the splitting mechanism 2, the setting of the fixed block 2031 and the sleeve 2032, combined with the use of the electric push rod 207, can achieve the fixation of the left cutter 204, and the right cutter 205 can split the junction box from the photovoltaic module as the electric push rod 207 moves in an extension and contraction manner.
[0068] In another embodiment of the present embodiment, both sides of the left cutter 204 and the right cutter 205 include side panels 206. When the right cutter 205 moves closer to the left cutter 204, an encirclement can be formed by the side panels 206, and the disassembled junction box is located in the encirclement. In addition, a recycling mechanism can be provided beside the conveying unit 105 and at the moving track of the X-axis moving unit. The disassembly mechanism 2 can transport the disassembled junction box to the recycling mechanism for recycling under the action of the slide rail 106.
