The shovel body includes a connected blade portion and a cutting edge portion. The heating component is configured to be connected at least to the cutting edge portion of the shovel body, thereby transferring heat to the cutting edge portion of the shovel body.

Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a lead wire lifting tool and a lead wire lifting device. Background Technology

[0002] The photovoltaic (PV) industry chain begins with upstream silicon raw materials, proceeding through metallic silicon refining, polycrystalline silicon preparation, silicon rod pulling, and silicon wafer cutting, before reaching the midstream production of solar cells and PV modules, and finally integrating downstream into PV power plant systems. In this process, although individual solar cells possess the basic function of converting solar energy into electrical energy, their inherent fragility and sensitivity to aging environments prevent them from being directly used as a stable and reliable power source. Therefore, the design and manufacturing of PV modules is the core of the solar power generation system, its core role being to efficiently and stably convert captured solar energy into electrical energy.

[0003] As a core component of a solar power generation system, the encapsulated photovoltaic module can be flexibly applied to various scenarios: in off-grid systems, it can store the converted electrical energy in batteries for emergencies or to power independent loads; while in grid-connected systems, it can directly connect the electrical energy to the grid, realizing the widespread supply and utilization of clean energy.

[0004] The production process of photovoltaic modules involves a series of complex procedures, including string welding, layout, stacking, lamination, glass bonding, EL visual inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, and junction box welding. To facilitate lamination, the busbar leads are bent to fit tightly against the glass surface before lamination. Before welding the junction box, the leads need to be straightened to facilitate their passage through the lead holes in the junction box, and then welding is completed.

[0005] To prevent air bubbles from forming in the center holes of photovoltaic modules, spacers (adhesive films) are added at the center holes. However, this can also lead to excessive adhesive overflow in the center holes, which can cause the leads to stick and result in a low success rate for lead picking machines, as well as problems such as lead pressing and lead bending.

[0006] Therefore, it is necessary to provide a wire-picking shovel and a wire-picking device to address the aforementioned technical problems.

[0015] The heating unit is configured as a heating wire.

[0016] In one embodiment, a plurality of the unit fitting cavities are arranged along a linear trajectory in at least one of the blade body portion and the blade edge portion.

[0021] A visual positioning component, which is mounted on the device frame.

[0022] In one embodiment, the number of displacement components is configured to be at least one, and the number of lead wire picks is configured to be at least two, with each displacement component connected to two lead wire picks.

[0023] In one embodiment, the displacement component includes:

The number of the second telescopic components is configured to be two, and the two second telescopic components are movably mounted on the linear guide component along the straight guide trajectory. Each telescopic end of the second telescopic component is equipped with a lead wire shovel.

[0027] In one embodiment, the displacement component includes:

[0028] An intermediate baffle is disposed on the linear guide member and is located between the two second telescopic members.

[0029] In the aforementioned wire-picking shovel and wire-picking device, when the blade of the shovel body performs the wire-picking operation, a heating component can transfer heat to the shovel body, causing it to raise its temperature—at least significantly increasing the temperature of the blade. Therefore, when the shovel body is used for wire picking, the higher temperature softens the silicone, making the wire picking process smoother and effectively improving the success rate.

[0048] See Figure 1 and Figure 2 As shown, this application provides a wire-picking scraper, which includes a scraper body 1000 and a heating component 2000. The scraper body 1000 can be made of a material with thermal conductivity, such as a metal. Figure 1 and Figure 2 From the two perspectives, it can be seen that the shovel body 1000 includes a connected blade part 1100 and a blade part 1200. The blade part 1100 and the blade part 1200 can be integrally molded or can be assembled together after being made separately. Those skilled in the art can choose the material and structural manufacturing method of the shovel body 1000 according to their needs, and no limitation is made here.

[0049] Continue reading Figure 1 and Figure 2As shown, in order to improve the success rate of wire picking, the wire picking scraper of this application integrates a heating component 2000 in the scraper body 1000, which has the ability to heat. Therefore, the heating component 2000 can be configured to be connected to at least the blade portion 1200 of the scraper body 1000, thereby transferring heat to at least the blade portion 1200. For example, in one embodiment, the heating component 2000 can be configured to be connected only to the blade portion 1200 of the scraper body 1000, thereby transferring heat only to the blade portion 1200; or the heating component 2000 can be configured to be connected to both the blade body portion 1100 and the blade portion 1200 of the scraper body 1000 simultaneously, thereby transferring heat to both the blade body portion 1100 and the blade portion 1200 simultaneously.

[0050] The connection between the heating component 2000 and the scraper body 1000 can be achieved through contact, adhesive, snap-fit, threaded connection, or plug-in connection. For example, in one embodiment, the scraper body 1000 may have a fitting cavity 3000, wherein the fitting cavity 3000 is at least located in the blade portion 1200, that is, the fitting cavity 3000 may be located only in the blade portion 1200, or the fitting cavity 3000 may be located simultaneously in the blade body portion 1100 and the blade portion 1200, so that the heating component 2000 can be assembled in the fitting cavity 3000 as needed to achieve heat transfer assembly between the heating component 2000 and the scraper body 1000.

[0051] The heating component 2000 can be selected from a variety of heating types, such as heating rod, heating wire (heating resistance wire), heating plate, heating block, etc. For example, in one embodiment, the heating component 2000 may include a plurality of heating unit components 2100, which are connected to each other, thereby enabling synchronous heating among the plurality of heating unit components 2100. Several heating units 2100 can be connected to different positions of at least one of the blade body 1100 and the blade edge 1200 as needed. That is, when several heating units 2100 are only connected to the blade body 1100, several heating units 2100 can be distributed at different positions of the blade body 1100; or when several heating units 2100 are only connected to the blade edge 1200, several heating units 2100 can be distributed at different positions of the blade edge 1200; or when several heating units 2100 are connected to both the blade body 1100 and the blade edge 1200, several heating units 2100 can be simultaneously distributed at different positions of the blade body 1100 and the blade edge 1200.

[0052] Therefore, by distributing the heating units 2100, they can be configured to transfer heat to different locations of at least one of the blade body 1100 and the cutting edge 1200, thereby achieving uniform heat transfer in a specific area of ​​the shovel body 1000 and ensuring uniform heating of the shovel body 1000. For example, when the heating units 2100 are only connected to the blade body 1100, they can be configured to transfer heat to different locations of the blade body 1100; or when the heating units 2100 are only connected to the cutting edge 1200, they can be configured to transfer heat to different locations of the cutting edge 1200; or when the heating units 2100 are connected to both the blade body 1100 and the cutting edge 1200, they can be configured to transfer heat to different locations of both the blade body 1100 and the cutting edge 1200 simultaneously.

[0053] Regarding the assembly of the aforementioned heating unit components 2100, in one embodiment, the aforementioned fitting cavity 3000 may include a plurality of unit fitting cavities 3100. Therefore, the aforementioned scraper body 1000 may have a plurality of unit fitting cavities 3100 as needed. These unit fitting cavities 3100 may be located in at least one of the blade body portion 1100 and the blade edge portion 1200. Specifically, the plurality of unit fitting cavities 3100 may be located only in the blade body portion 1100, or only in the blade edge portion 1200, or simultaneously in both the blade body portion 1100 and the blade edge portion 1200. Therefore, the plurality of heating unit components 2100 may be assembled into different unit fitting cavities 3100 as needed, thus flexibly arranged in the blade body portion 1100 or the blade edge portion 1200 of the scraper body 1000.

[0054] In one embodiment, a plurality of unit fitting cavities 3100 are arranged along a linear trajectory in at least one of the blade body portion 1100 and the blade edge portion 1200. This linear trajectory can be a straight line, a curved line, or a continuous or discontinuous trajectory. The design of the linear trajectory determines the distribution of the plurality of unit fitting cavities 3100, and consequently the distribution of the plurality of heating unit components 2100, affecting the heating effect of the heating assembly 2000 on the scraper body 1000. Those skilled in the art can design this according to actual needs, and no limitation is made here.

[0055] With the aforementioned structural design, when the blade 1200 of the scraper body 1000 performs the wire-picking operation, the heating component 2000 can transfer heat to the scraper body 1000, causing the scraper body 1000 to receive heat and raise its own temperature. This requires a significant increase in the temperature of the blade 1200. Therefore, when the scraper body 1000 is used for wire picking, the higher temperature can soften the silicone, making the wire picking process smoother and effectively improving the success rate.

[0056] See Figures 3 to 5 As shown, this application provides a wire-picking device, which includes a device frame 100, a displacement component 200, a wire-picking shovel, and a vision positioning component 300. The displacement component 200 is mounted on the device frame 100 and connected to the wire-picking shovel. The displacement component 200 is configured to control the movement of the wire-picking shovel relative to the device frame 100. This movement can be planar movement in two-dimensional space or three-dimensional movement in three-dimensional space. Those skilled in the art can design the displacement control capability of the displacement component 200 according to actual needs, thereby determining the spatial movement capability of the wire-picking shovel, which is not limited here.

[0057] Continue reading Figures 3 to 5 As shown, in one embodiment, the number of displacement components 200 can be configured to be at least one, and the number of lead wire pickers can be configured to be at least two, with each displacement component 200 connected to two lead wire pickers. Therefore, each displacement component 200 can be combined with two lead wire pickers to form a mechanism, which can be one or more, for example, see [reference needed]. Figure 4 As shown, the number of displacement components 200 can be configured to be three, and the number of lead wire pickers can be configured to be six. Each displacement component 200 is connected to two lead wire pickers, and the three displacement components 200 can be combined with the six lead wire pickers to form three sets of mechanisms. Those skilled in the art can design according to actual needs, and no limitation is made here.

[0058] Continue reading Figure 5As shown, the visual positioning component 300 can be mounted on the device frame 100. The visual positioning component 300 can utilize visual recognition capabilities to determine the specific situation during the lead-in lifting process. For example, the visual positioning component 300 can use cameras or webcams to acquire data such as photos and videos, and based on the acquired data, determine the visual positioning before lead-in lifting and whether the quality is acceptable after lead-in lifting. Depending on the requirements, one or more visual positioning components 300 can be set. These components can visually recognize the lead-in lifting process of one or more lead-in lifting blades according to design requirements, helping to monitor the quality of the lead-in lifting. Therefore, through the visual positioning and AI judgment of the visual positioning component 300, automated inspection can be achieved, improving production efficiency and accuracy, reducing the occurrence of defects, and lowering production costs and the workload of manual review.

[0059] In one embodiment, the displacement assembly 200 may include a first telescopic component 210, a linear guide component 220, and a second telescopic component 230. The first telescopic component 210 and the second telescopic component 230 may be mechanical claw telescopic rods, electrically controlled telescopic rods, hydraulic telescopic rods, pneumatic telescopic rods, etc. The first telescopic component 210 extends and retracts along a first straight line trajectory, which may be defined as extension and retraction in the Z-axis direction (height direction).

[0060] The linear guide component 220 is connected to the telescopic end of the first telescopic component 210. The linear guide component 220 has a linear guide trajectory. For example, the linear guide component 220 can be provided with a linear groove, linear slide rail, etc. to form the above-mentioned linear guide trajectory. The linear guide trajectory is perpendicular to the first linear trajectory, which can limit the linear guide trajectory to lateral horizontal movement in the X-axis or Y-axis direction (horizontal direction).

[0061] The second telescopic component 230 extends and retracts along the second straight track, which is parallel to the first straight track. The number of the second telescopic components 230 is configured to be two. The two second telescopic components 230 are movably assembled on the linear guide component 220 along the straight guide track. Each telescopic end of the second telescopic component 230 is equipped with a wire-picking shovel. For example, each telescopic end of the second telescopic component 230 can be equipped with a wire-picking shovel through a structure such as a gripper.

[0062] In one embodiment, the displacement component 200 may further include an intermediate baffle 240, which is disposed on the linear guide component 220 and located between the two second telescopic components 230. The intermediate baffle 240 may also extend along the second linear trajectory of the second telescopic component 230 to match the movement state of the second telescopic component 230 extending and retracting along the second linear trajectory.

[0063] When the photovoltaic module moves to the area under the lead wire picker, the visual positioning component 300 first performs visual positioning. After confirming OK, the first telescopic component 210 extends downward along the first straight trajectory, and the heating component 2000 begins to heat the lead wire body 1000. Then, the two second telescopic components 230 move laterally along the straight guide trajectory, bringing their respective lead wire bodies 1000 closer together until the lead wire is picked onto the intermediate baffle 240. Afterward, the second telescopic components 230 move upward along the second straight trajectory, thereby causing the two lead wire bodies 1000 to move upward synchronously, straightening the lead wire along the intermediate baffle 240 during this process. This completes the lead wire picking operation.

[0064] The first telescopic component 210, the second telescopic component 230, and the linear guide component 220 return to their original positions. The heating component 2000 stops heating, and the visual positioning component 300 takes another picture to perform AI judgment on whether the lead wire picking was successful. If OK, the component proceeds to the next stage; if NG, an alarm is triggered, prompting manual review.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
