[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are presented in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be realized even without these technical details and based on various changes and modifications of the following embodiments. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific embodiments of the present application, and the embodiments can be combined and referenced with each other without contradiction.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application; the description and claims of this application as well as the above abstract are intended to cover any and all adaptations or variations of well known methods, articles, materials, compositions, and

[0025] In the description of the embodiments of the present application, unless otherwise explicitly defined and limited, the technical terms "mounting", "connection", "connecting" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through an intermediate medium, can be internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0026] With the continuous increase of the installed capacity of photovoltaic modules, the production efficiency of photovoltaic modules also needs to be continuously improved. Photovoltaic modules will go through different process operation processes in the production process, including the process of pasting bar code. Because the manual tearing and pasting of bar code consumes a long time, it is not conducive to improving the production efficiency of photovoltaic modules. Moreover, the attachment position of the bar code deviates greatly, affecting the overall appearance of the photovoltaic module.

[0027] At present, the assembly process of photovoltaic modules has realized automatic assembly line production. The assembly process includes laying the back plate. When laying the back plate, the lead wire on the photovoltaic module needs to pass through the lead wire hole on the back plate and be led out, and the lead wire is in an upright state. After the back plate is laid, lamination operation is performed, and the lead wire needs to be bent and flattened during lamination operation. After the lead wire is bent, the bar code pasting process is often accompanied. In order to facilitate the traceability of product production information, according to the process requirements, a bar code will be pasted on the back plate and the busbar of the photovoltaic module. The bar code on the busbar is pasted before the back plate is laid. In order to save the configuration of bar code printing equipment, two same bar codes will be printed at the busbar bar code attachment station, and the bar code to be attached on the back plate will be attached on the lower surface edge side of the photovoltaic module. With the movement of the photovoltaic module to the subsequent station, the bar code is attached on the back plate after the back plate is laid. In this process, an automatic device capable of tearing and pasting bar codes is needed to tear and paste the bar code on the photovoltaic module to the back plate.

[0028] However, existing adsorption mechanisms suffer from significant positional errors after barcode tearing, and the barcodes may protrude, leading to wrinkles and unstable positioning. This is because the adsorption mechanism uses a single vacuum channel, and the action of the pressing cylinder and the vacuum opening time after barcode tearing are fixed. The barcodes themselves are soft and have varying adhesive properties, resulting in uneven barcodes after tearing. Furthermore, the tearing process itself introduces uncertain and difficult-to-eliminate errors. The barcodes are soft, and vibrations during photovoltaic module positioning can cause positioning errors. Additionally, the varying adhesive properties of each barcode contribute to the unpredictable errors in tearing barcodes from the photovoltaic module. These two issues reduce the success rate of tearing barcodes from the back of the photovoltaic module and subsequent barcode application, increasing maintenance costs.

[0029] To improve the success rate of barcode tearing and the stability of barcode affixing during photovoltaic module production, and to reduce manual processing time, some embodiments of this application provide a suction device. The suction device features a dual-vacuum channel adsorption mechanism, which solves the problem of uneven barcode protrusion during the tearing process, ensuring the barcode is flat and free of wrinkles or protrusions, thus making barcode affixation more stable.

[0030] The following is combined with Figures 1 to 6 The structure of the suction device provided in some embodiments of this application is described. The suction device is used to pick up barcodes and attach them to photovoltaic modules.

[0031] like Figures 1 to 6 As shown, some embodiments of this application provide an adsorption device including a base 11, a clamping member 12, and an adsorption mechanism 13. The base 11 can be changed between a first position and a second position. The clamping member 12 is positioned along a first direction perpendicular to the plane of the photovoltaic module 20. Figure 1 The adsorption mechanism 13 is movably disposed on the base 11 in the direction indicated by the middle arrow X. The adsorption mechanism 13 is movably disposed on the base 11 along a first direction. The adsorption mechanism 13 includes a second direction (parallel to the plane of the photovoltaic module 20)... Figure 1 The adsorption member 131 (in the direction indicated by the middle arrow Y) rotates. The adsorption member 131 is provided with a first adsorption channel 1311 and a second adsorption channel 1312 spaced apart from each other, and a first adsorption port 1313 and a second adsorption port 1314 located on the same plane. The first adsorption port 1313 communicates with the first adsorption channel 1311, and the second adsorption port 1314 communicates with the second adsorption channel 1312. When the base 11 is in the first position, the first adsorption port 1313 adsorbs the barcode 21 after the pressing member 12 presses against it, and the second adsorption port 1314 adsorbs the barcode 21 after the pressing member 12 leaves it. After adsorbing the barcode 21, the adsorption mechanism 13 moves away from the photovoltaic module 20, tearing the barcode 21 off the edge of the photovoltaic module 20. When the base 11 is in the second position, the adsorption mechanism 13 moves towards the photovoltaic module 20, attaching the barcode 21 to the photovoltaic module 20.

[0032] The base 11 can form a mounting base for other components, so that the device body can be transformed between the first position of tearing the strip code 21 and the second position of attaching the strip code 21. The base 11 can be connected with a mechanical hand or a multi-axis transfer module 101 mounted on the support 10, so as to realize position transformation under the driving of the mechanical hand or the multi-axis transfer module 101. The base 11 is mounted on the flow conveying line of the photovoltaic assembly 20. The photovoltaic assembly 20 is in a position-fixed state when reaching the strip code 21 station, and can be aligned by positioning. The base 11 is at a distance from the photovoltaic assembly 20, and can be transformed above the photovoltaic assembly 20, so as to realize the actions of tearing the strip code 21 and attaching the strip code 21 by the suction device.

[0033] The pressing member 12 serves to apply pressure to the strip code 21, so as to avoid the swing deformation of the strip code 21 in the process of suction due to lack of fixation. After the base 11 reaches the first position of tearing the strip code 21, the pressing member 12 can move towards the photovoltaic assembly 20 relative to the base 11, and stop pressing on the strip code 21. The strip code 21 can be flattened.

[0034] The suction mechanism 13 is a part for suctioning the strip code 21. The suction mechanism 13 can perform the suction action of the strip code 21, so as to fix the strip code 21. Thus, the actions of tearing the strip code 21 and attaching the strip code 21 are performed. The suction mechanism 13 can move along a first direction perpendicular to the plane where the photovoltaic assembly 20 is located relative to the base 11, so as to approach the strip code 21. Meanwhile, the suction member 131 of the suction mechanism 13 can rotate relative to the base 11 around a second direction parallel to the plane where the photovoltaic assembly 20 is located, so as to adjust the direction relative to the strip code 21. For the strip code 21 attached to the lower surface of the photovoltaic assembly 20, the suction member 131 can be adjusted to face the strip code 21 by rotation. And when attaching the strip code 21, the suction member 131 is adjusted to face the upper surface of the photovoltaic assembly 20. The suction member 131 has different suction channels, and different suction channels are connected with corresponding suction ports, so as to be suctioned at different positions of the strip code 21. And the different suction ports adopt a separate suction form, that is, the first suction port 1313 is pre-suctioned on the strip code 21, and the second suction port 1314 is suctioned on the strip code 21 after the pressing member 12 leaves the strip code 21 and the strip code 21 is flattened due to its own elasticity. Thus, the flatness of the strip code 21 is ensured.

[0035] The adsorption device provided in some embodiments of this application fixes the barcode 21 through the adsorption action of the adsorption mechanism 13. The adsorption member 131 of the adsorption mechanism 13 is provided with different adsorption channels and corresponding connected adsorption ports. The different adsorption channels can adsorb in a step-by-step manner, thereby cooperating with the pressing member 12 to provide a basis for flattening the barcode 21. During the adsorption process of the barcode 21, wrinkles and unevenness of the barcode 21 can be avoided, which would affect the adhesion effect. This ensures the adhesion effect of the barcode 21.

[0036] In some embodiments, there may be multiple first adsorption ports 1313 and multiple second adsorption ports 1314, and the multiple first adsorption ports 1313 and multiple second adsorption ports 1314 are arranged in the same direction.

[0037] Different adsorption ports can be arranged along a straight line and used for separate adsorption along the same line. Each adsorption port is formed at the end of its corresponding adsorption channel, and each adsorption channel can be configured into a vacuum environment by a vacuum source, so that different adsorption ports can adsorb different areas of the barcode 21. By increasing the number of adsorption ports, the adsorption stability of the barcode 21 by different adsorption ports can be ensured, while ensuring the adsorption range of the barcode 21. This prevents the barcode 21 from easily slipping or falling off during the adsorption process.

[0038] In addition, the multiple first adsorption ports 1313 and the multiple second adsorption ports 1314 can be arranged in an array.

[0039] In other words, the first suction port 1313 and the second suction port 1314, which perform the suction action, can be arranged in multiple rows and columns. This effectively increases the suction range and ensures the overall fixation of the barcode 21.

[0040] like Figure 3 As shown, the adsorption ports can be arranged in a two-row, multi-column configuration to accommodate the elongated shape of barcode 21, thus achieving a stable adsorption effect on barcode 21.

[0041] In some embodiments, the adsorption mechanism 13 may further include a driving member 132 and a connecting seat 133. The driving member 132 is movably disposed on the base 11 along a first direction, the connecting seat 133 is connected to the output end of the driving member 132, and the adsorption member 131 is connected to the connecting seat 133.

[0042] The driving member 132 is movably arranged on the base 11 in the first direction as a driving source for driving the suction accessory 131 to rotate. The output end of the driving member 132 is connected with a connecting seat 133, and the suction accessory 131 is connected with the connecting seat 133. The connecting seat 133 can provide a mounting basis for the suction accessory 131, so that the suction accessory 131 can be in a suitable mounting position and can be sucked to the bar code 21 without interference. The connecting seat 133 can form an assembly platform 134 and a fixing hole 135. The suction accessory 131 can be provided with a mounting hole 1319, and when the suction accessory 131 is matched with the assembly platform 134, a fastener can be connected through the mounting hole 1319 and the fixing hole 135, so as to facilitate the installation of the suction accessory 131. The connecting seat 133 is driven to rotate by the driving member 132, so as to adjust the suction direction of the suction accessory 131. In order to drive the suction accessory 131 to change between the direction towards the lower surface of the photovoltaic module 20 and the direction towards the upper surface of the photovoltaic module 20. When the suction accessory 131 is towards the lower surface of the photovoltaic module 20, the bar code 21 attached to the edge of the lower surface of the photovoltaic module 20 can be sucked, so as to tear the bar code 21 from the edge of the lower surface of the photovoltaic module 20. When the suction accessory 131 is towards the upper surface of the photovoltaic module 20, the suctioned bar code 21 can be attached to the middle of the upper surface of the photovoltaic module 20.

[0043] As shown in Figure 3 The suction accessory 131 can include oppositely arranged first and second surfaces 1315 and 1316. The first and second suction ports 1313 and 1314 are located on the first surface 1315, and the second surface 1316 is attached to the connecting seat 133.

[0044] The first and second surfaces 1315 and 1316 are two surfaces with larger areas of the suction accessory 131. The suction port is located on the first surface 1315 for attaching the bar code 21 to the bar code 21. The second surface 1316 cooperates with the connecting seat 133 to ensure the stability of the suction accessory 131 when connected with the connecting seat 133. By keeping the surface of the suction accessory 131 provided with the suction port and the cooperating surface of the other components in a relative relationship, a vacuum channel can be formed at the component cooperation position to connect the vacuum source. Moreover, the interference on the suction port can be reduced.

[0045] In some embodiments, the suction accessory 131 can be provided with first and second inner cavities 1301 and 1302, the first inner cavity 1301 being in communication with the first suction channel 1311, and the second inner cavity 1302 being in communication with the second suction channel 1312.

[0046] The inner cavities arranged in the suction accessory 131 can provide a larger communication space. Different inner cavities can be in communication with different suction channels, so as to facilitate the connection of the vacuum source through the inner cavities and the simultaneous communication of multiple suction channels.

[0047] In addition, the first inner cavity 1301 and the second inner cavity 1302 can extend to the surface of the connecting seat 133, and the connecting seat 133 is provided with a first vacuum passage 1331 and a second vacuum passage 1332, one end of the first vacuum passage 1331 being in communication with the first inner cavity 1301, and one end of the second vacuum passage 1332 being in communication with the second inner cavity 1302.

[0048] That is, the inner cavities of the suction accessory 131 are in a hollow shape on the surface of the connecting seat 133. Through the connection and cooperation between the suction accessory 131 and the connecting seat 133, a closed effect is formed on the inner cavities of the suction accessory 131. At the same time, the connecting seat 133 is provided with different vacuum passages, and the different vacuum passages are in communication with the corresponding inner cavities. By arranging the vacuum passages in the connecting seat 133, the pipeline can be connected to the vacuum source, so as to realize the suction control of the suction passages in the suction accessory 131.

[0049] As shown in Figure 3 The first surface 1315 can be provided with a first suction area 1317 and a second suction area 1318, the first suction area 1317 and the second suction area 1318 being arranged at intervals, the first suction port 1313 being located in the first suction area 1317, and the second suction port 1314 being located in the second suction area 1318.

[0050] That is, different suction ports are distributed in different areas on the surface of the suction accessory 131. In addition, the different suction areas are spaced apart, so that the different suction ports are spaced apart by a certain distance. The stretching of the bar code 21 can be provided. In addition, the mutual influence between the different suction ports can be avoided, and the suction effect of the suction ports located in different suction areas on the bar code 21 can be ensured.

[0051] In actual cases, the first suction port 1313 and the second suction port 1314 can be symmetrically arranged on the first surface 1315. By keeping the different suction ports symmetrically arranged, the manufacturing form of the suction accessory can be simplified, and the suction force of the different suction ports on the bar code can be ensured, and the stability during suction of the bar code 21 can be improved.

[0052] In some embodiments, the first suction port 1313 and / or the second suction port 1314 can be any one of a circle, a square, a rectangle, and an ellipse.

[0053] Each suction port can be arranged in a required shape according to actual conditions. By arranging the suction port in a regular shape such as a circle or a square, the manufacturing difficulty of the suction accessory 131 can be reduced, and the manufacturing of the suction passage can be simplified.

[0054] As shown in Figure 3As shown, each suction port is arranged in a circular shape. Meanwhile, the diameters of the plurality of first suction ports 1313 can be the same, and the diameters of the plurality of second suction ports 1314 can be the same. By keeping the diameters of the suction ports the same, the suction force of different suction ports on the bar code 21 can be kept consistent, and the stability of the suction of the bar code 21 can be ensured.

[0055] As shown in the drawings, the suction device can further include a detection camera 14 arranged on the base 11, and the detection camera 14 is used to detect the attachment position of the bar code 21. Figure 1

[0056] The detection camera 14 can detect the position of the bar code 21 sucked by the suction member 131, and further detect the attachment position of the bar code 21. In the process of attaching the bar code 21, whether the attachment position of the bar code 21 is appropriate can be determined by the detection of the detection camera 14. The accuracy of the attachment position of the bar code 21 can be improved, and the attachment effect of the bar code 21 can be ensured.

[0057] In some embodiments, the suction device can further include a visual detection mechanism 14 used to detect the position of the bar code 21 on the photovoltaic module 20.

[0058] As shown in the drawings, the visual detection mechanism 14 can be arranged adjacent to the support 10. The visual detection mechanism 14 can include a support frame, a light source, a camera, and corresponding visual operation software to achieve the required functions. After the photovoltaic module 20 is in place, the visual detection mechanism 14 can detect whether the bar code 21 is attached at the edge of the photovoltaic module 20 and the attachment position of the bar code 21. Thus, whether the suction mechanism 13 performs the action of tearing the bar code 21 and where the action of tearing the bar code 21 is performed can be controlled. Figure 6 The visual detection mechanism 14 can calibrate the bar code 21 in advance and teach the position. After the action of tearing the bar code 21 is completed, the bar code 21 can be photographed by the camera to correct the position of tearing the bar code 21, so that the attachment position of the bar code 21 can be accurate each time, thereby eliminating the error of the bar code 21 in the process of tearing and suction. That is, the visual detection mechanism 14 can play a visual compensation function, correct the position after tearing the bar code 21 each time, eliminate the error of tearing the bar code 21, make the attachment position of the bar code 21 more accurate, and make the attachment quality of the bar code 21 more stable.

[0059] The suction device provided by some embodiments of the present application adopts a bar code suction mechanism with double vacuum channels to realize the flat suction of the bar code 21. Moreover, the bar code 21 can be detected at both the position of tearing the bar code 21 and the position of attaching the bar code 21, so as to eliminate the error of tearing the bar code 21, make the position of attaching the bar code 21 more accurate, and improve the attachment quality of the bar code 21.

[0060]

[0061] ​​In actual situation, the bar code 21 is attached to the lower surface of the photovoltaic module 20 and has a section of overhanging extending from the side edge of the photovoltaic module 20. The double-vacuum-channel bar code suction mechanism includes equal number of equidistant small holes in different suction areas, and is equipped with two vacuum generators with adjustable pressure values to adjust the suction pressure in real time. During the tearing of the bar code 21, the base 11 moves to the first position for tearing the bar code 21. The suction mechanism 13 is close to the position of the bar code 21 at the edge of the photovoltaic module 20 and is also close to the position of the visual detection mechanism 14. Through the position information of the bar code 21 fed back by the visual detection mechanism 14, the suction mechanism 13 moves to the position of the bar code 21. At the same time, the driving member 132 drives the suction member 131 to rotate, so that the first surface 1315 of the suction member 131 faces upward, i.e., toward the lower surface of the photovoltaic module 20. The suction member 131 suctions the light surface of the bar code 21 from below.

[0062] During the suction process, the lower pressing cylinder drives the pressing member 12 to lower, the first suction channel 1311 is opened to suction the bar code 21. The lower pressing cylinder drives the pressing member 12 to lift, the second suction channel 1312 is opened to suction the bar code 21, so as to complete the whole suction process. When the lower pressing cylinder drives the pressing member 12 to lift, if the bar code 21 is convex, it will be straightened due to its elasticity. At this time, the second suction channel 1312 is opened, and the bar code 21 is suctioned flat on the suction mechanism 13. The pressing member 12 is lowered to ensure that the bar code 21 is suctioned flat and stably on the first surface 1315 of the suction member 131. The suction mechanism 13 is lowered to tear the bar code 21 from the edge of the photovoltaic module 20.

[0063] After the tearing of the bar code 21 is completed, the driving member 132 drives the suction member 131 to rotate by 180°, so that the first surface 1315 of the suction member 131 faces downward. Thus, the adhesive surface of the bar code 21 faces downward, which is convenient for subsequent attachment of the bar code 21. Through the information fed back by the detection camera 14, the base 11 moves to the second position for attaching the bar code 21, and the suction mechanism 13 is lowered to complete the attaching of the bar code 21.

[0064] The suction device provided by some embodiments of the present application is designed as a double-channel mechanism for the original single-vacuum-channel bar code suction mechanism, is equipped with two vacuum generators with adjustable pressure values, solves the situation that the bar code 21 is convex after being torn, reduces the wrinkle phenomenon during the attachment of the bar code 21, improves the flatness during the attachment of the bar code 21, and makes the attachment quality of the bar code 21 more stable.
