Detailed Implementation

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] During the production of photovoltaic modules, the process of tearing off the sealing tape can cause EVA (Ethylene-Vinyl Acetate Copolymer) particles to splash and adhere to the surface of the photovoltaic module. Because EVA particles are sticky and difficult to fall off naturally, they may be misjudged as internal foreign objects by automatic optical inspection equipment, resulting in unqualified photovoltaic modules and reduced production efficiency.

[0023] Please see Figure 1To address the aforementioned issues, this application provides a foreign matter handling device 100, comprising a detection mechanism 1 and a processing mechanism 2. The detection mechanism 1 detects foreign matter on the surface of a photovoltaic module. The processing mechanism 2 includes a motion component 21 and an adhesion component 22. The motion component 21 is electrically connected to the detection mechanism 1 and drives the adhesion component 22 to move. The adhesion component 22 has an adhesive working surface for contacting the photovoltaic module surface. When the detection mechanism 1 detects foreign matter on the photovoltaic module surface, it causes the motion component 21 to move the adhesion component 22 to contact the photovoltaic module surface to adhere the foreign matter, thereby removing the foreign matter from the photovoltaic module surface, preventing the foreign matter from affecting the photovoltaic module's yield rate, and improving production efficiency.

[0024] In an optional implementation, the detection mechanism 1 can detect foreign objects using methods such as infrared light, laser, or imaging. Please refer to [link / reference]. Figure 1 In some embodiments, the detection mechanism 1 includes a camera component 11, which is electrically connected to the motion component 21. The camera component 11 is used to capture images of foreign objects on the surface of the photovoltaic module. By capturing images of the photovoltaic module surface, the camera component 11 can intuitively obtain detailed information such as the shape, size, and location of the foreign objects. For foreign objects such as EVA particles that are sticky and irregularly shaped, the camera component 11 can clearly identify their boundaries and adhesion state, reducing detection errors. The images captured by the camera component 11 can be directly converted into coordinate signals and transmitted to the control system. After receiving the coordinate signals, the control system controls the motion component 21 to move, driving the adhesion component 22 to adhere to the area where the foreign object is located.

[0025] In an optional implementation, the motion component 21 may be a robotic arm or a linear module, etc.

[0026] In this embodiment of the application, the first direction is as follows: Figure 1 As shown in the X direction, the height direction of the support frame 211 is as follows: Figure 1 Y direction shown.

[0027] Please see Figure 1 In some embodiments, the motion component 21 includes a support frame 211 and a first linear module 212. The first linear module 212 is connected to the support frame 211 and is driven to the adhesion component 22. The first linear module 212 is used to drive the adhesion component 22 to move along a first direction, which intersects with the height direction of the support frame 211. The support frame 211 can support the first linear module 212 and the adhesion component 22, enabling the first linear module 212 to drive the adhesion component 22 to move stably. The first linear module 212 has high motion precision and strong motion controllability, and can drive the adhesion component 22 to accurately remove foreign objects from the surface of the photovoltaic module.

[0028] In an optional implementation, the first linear module 212 may be a ball screw linear module, a synchronous belt and pulley linear module, a gear and rack linear module, etc.

[0029] For example, taking the first linear module 212 as a ball screw linear module, the first linear module 212 includes a drive motor, a guide rail, a lead screw, and a sliding seat. The guide rail extends along a first direction. The main body of the drive motor is fixed on the guide rail. One end of the lead screw along its own length is connected to the output end of the drive motor, and the other end is rotatably connected to the guide rail. The sliding seat is drivenly connected to the lead screw and also connected to the adhesion component 22, and the sliding seat is slidably connected to the slide rail of the guide rail. The drive motor drives the lead screw to rotate, so that the sliding seat moves along the lead screw, thereby driving the adhesion component 22 to move along the first direction.

[0030] Please see Figure 1 In some embodiments, the motion component 21 further includes a second linear module 213, which is connected to the drive end of the first linear module 212. The drive end of the second linear module 213 is connected to the adhesion component 22, and the second linear module 213 is used to drive the adhesion component 22 to move along the height direction of the support frame 211. The second linear module 213 allows for adjustment of the height of the adhesion component 22, thereby adapting to photovoltaic modules of different thicknesses and adjusting the distance between the adhesion component 22 and the surface of the photovoltaic module to avoid damaging the photovoltaic module.

[0031] In optional embodiments, the second linear module 213 can be a ball screw linear module, a synchronous belt and pulley linear module, a gear and rack linear module, etc. The working principle of the second module is similar to that of the first linear module 212, and will not be described again here.

[0032] Please see Figure 1 In some embodiments, the support frame 211 includes support legs 2111 and support beams 2112. The support beams 2112 are located at the top of the support legs 2111 along their own height direction and are connected to the first linear module 212. The support frame 211, including the support legs 2111 and the support beams 2112, can distribute the load and improve the structural strength. The support legs 2111 and the support beams 2112 provide movement space for the adhesion component 22, adapting to different positions of the photovoltaic module and making the movement of the adhesion component 22 above the photovoltaic module surface more flexible.

[0033] Please see Figure 1In some embodiments, the support beam 2112 includes two first support members 2112a and a second support member 2112b. The two first support members 2112a are arranged opposite each other along a first direction. The two ends of the second support members 2112b along the first direction are respectively connected to the middle of one of the first support members 2112a. Both ends of each first support member 2112a are connected to the top of the support leg 2111. The two ends of the first linear module 212 along the first direction are respectively connected to one of the first support members 2112a. The second support members 2112b of the support beam 2112 are cross-connected to the first support members 2112a, which can strengthen and limit the first support members 2112a. It can be understood that the first linear module 212 and the second support member 2112b are arranged in parallel. The load of the first linear module 212 is transferred to the support leg 2111 through the two first support members 2112a, which can distribute the load and improve the support stability of the support frame 211.

[0034] In optional embodiments, the adhesive component may be a flat adhesive plate, a multi-directional adhesive wheel, an adhesive roller, an adhesive roller 222, an adhesive shaft, etc.

[0035] Please see Figure 1 In some embodiments, the adhesion component 22 includes a roller support 221 and an adhesive roller 222. The adhesive roller 222 has an adhesive working surface and is rotatably connected to the roller support 221 about its own axis. The roller support 221 is connected to the motion component 21. By rotating about its own axis, the adhesive roller 222 can continuously contact the surface of the photovoltaic module during movement, forming a continuous adhesion action. Compared with fixed adhesive plates, it does not require frequent stops or resets, making it suitable for assembly line operations or scenarios requiring large-area, high-frequency adhesion, significantly improving work efficiency. The cylindrical structure of the adhesive roller 222 allows its adhesive working surface to uniformly cover an area of ​​a certain width, and it can apply adhesion force more evenly during rolling, avoiding excessively strong or weak local adhesion force and ensuring consistent adhesion effect. Rolling friction is much less than sliding friction. When the adhesive roller 222 rotates and contacts the object during operation, it can reduce the frictional resistance with the contact surface, reduce the energy consumption of the motion component 21, and reduce wear on the roller surface, extending its service life. The roller support 221 distributes the weight of the adhesive roller 222 and the force during operation to the moving component 21, avoiding structural deformation or damage caused by single-point force.

[0036] In an optional embodiment, the adhesive roller 222 can be a disposable roller, meaning that a new adhesive roller 222 is replaced after each use. Alternatively, the adhesive roller 222 can have multiple adhesive working surfaces, allowing for reuse of an adhesive roller 222 by peeling off the used adhesive working surfaces to expose the unused adhesive working surfaces.

[0037] In an optional embodiment, the roller support 221 is connected to the drive end of the second linear module 213.

[0038] Please see Figure 1 In some embodiments, the roller support 221 includes a first segment 2211 and a second segment 2212 that are bent and connected. The first segment 2211 intersects the axis of the adhesive roller 222, and the second segment 2212 is parallel to the axis of the adhesive roller 222. One end of the first segment 2211 is connected to the motion component 21, and the other end is connected to one end of the second segment 2212. The other end of the second segment 2212 is connected to one end of the adhesive roller 222 along its own axial direction. The rolling element, including the bent and connected first segment 2211 and second segment 2212, can provide movement space for the rolling of the adhesive roller 222 and reduce the impact on the rolling of the adhesive roller 222.

[0039] In an optional embodiment, the adhesive roller 222 is provided with a first section 2211 and a second section 2212 at both ends along its own axis, which can improve the support stability of the roller support 221 and reduce its swaying during the rolling process.

[0040] Please see Figure 1 In some embodiments, the roller support 221 further includes a third segment 2213, which is parallel to the axis of the adhesive roller 222. One end of the third segment 2213 along its length is connected to the moving component 21, and the other end is connected to the end of the first segment 2211 away from the second segment 2212. In other words, the third segment 2213 is arranged parallel to the second segment 2212. The third segment 2213, being parallel to the roller axis, can directly bear the axial force of the adhesive roller 222, and at the same time, together with the first segment 2211 and the second segment 2212, resists torque, preventing the support from twisting due to torque and ensuring the offset of the roller's rotational position.

[0041] Please see Figure 1In some embodiments, the roller support 221 further includes a fourth segment 2214, which intersects the axis of the adhesive roller 222. One end of the fourth segment 2214 along its own length is connected to the moving component 21, and the other end is connected to the end of the third segment 2213 away from the first segment 2211. In other words, the fourth segment 2214 is parallel to the first segment 2211. Adding the fourth segment 2214 can evenly distribute the force on the adhesive roller 222 to the first segment 2211, the second segment 2212, the third segment 2213, and the fourth segment 2214, avoiding structural distortion caused by unilateral force. The fourth segment 2214 intersects the roller axis (i.e., is parallel to the first segment 2211), and its extension direction is consistent with the direction of the roller's radial force. When the roller is subjected to pressure perpendicular to the axis, the fourth segment 2214 can resist radial deformation together with the first segment 2211, while the third segment 2213 and the second segment 2212 resist axial deformation, thereby forming multi-directional constraints in three-dimensional space and reducing the skewness of the roller support 221.

[0042] Please see Figure 1 In an optional embodiment, the fourth segment 2214 of the roller support 221 is connected to the drive end of the second linear module 213 of the motion component 21.

[0043] Please see Figure 1 The working principle of the foreign object handling device 100 of this application will be described below with specific embodiments: After the camera component 11 of the detection mechanism 1 captures the foreign object on the surface of the photovoltaic module, the first linear module 212 of the motion component 21 of the control mechanism 2 drives the second linear module 213 and the adhesion component 22 to move along the first direction. At the same time, the second linear module 213 drives the roller support 221 of the adhesion component 22 to descend, so that the adhesive roller 222 connected to the roller support 221 contacts the foreign object and adheres to it, thereby completing the removal of the foreign object.

[0047] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
