Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and more specifically, to a system and method for batch laying solar cells on the wings of a solar fixed-wing unmanned aerial vehicle (UAV). Background Art

[0002] With the global emphasis on clean energy and the enhancement of environmental protection awareness, solar energy, as a pollution-free and renewable energy source, has been continuously expanded in various fields. The rapid development of UAV technology has made it possible to combine solar energy with UAVs to meet the needs of people for long-duration, long-distance, and low-cost flight operations, while reducing the dependence on traditional fossil fuels and reducing carbon emissions during the operation of UAVs. Solar UAVs can utilize solar energy for power supply, meet the energy consumption required for flight, and charge their own batteries, enabling continuous flight in the absence / weak light environment. The continuous flight condition poses high requirements on the wing performance of UAVs.

[0003] In the field of solar fixed-wing UAVs, for the wings with solar cells, their composition structures are either that the transparent wing skin is laid with solar cells on the internal support, or an integrated wing, where the solar cells are used as one layer of the skin for multi-layer laying to form a composite skin, or there are other methods. Generally speaking, for the integrated wing, it has great advantages in terms of strength and weight, but the production efficiency and quality yield are still very backward. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a system and method for batch laying solar cells on the wings of a solar fixed-wing UAV.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The present invention discloses a system for batch laying solar cells on the wings of a solar fixed-wing UAV, including a mold and a profiling tooling. An installation surface one and an installation surface two are connected on the upper part of the mold. The installation surface two is inclined, and the end of the installation surface two connected to the installation surface one is higher than the end of the installation surface two away from the installation surface one. The profiling tooling includes an operation surface one and an operation surface two. The operation surface one has the same shape as the installation surface one, and the operation surface two has the same shape as the installation surface two; a transfer tooling is further included, and the transfer tooling includes an installation rod, and a plurality of adsorption mechanisms are installed on the installation rod.

[0007] Further, the adsorption mechanism includes an installation block, the installation block is installed on the installation rod, a suction cup is installed under the installation block, and a pipeline is connected to the suction cup and passes through the installation block.

[0008] Further, a fixing block is connected to the upper part of the installation block. A fixing hole is provided on the fixing block. An installation groove is provided on one side of the installation rod facing the fixing block. The installation groove is arranged along the length direction of the installation rod. A bolt is connected between the fixing block and the installation rod. The bolt passes through the fixing hole and is screwed into the installation groove.

[0009] Further, positioning members are installed at both ends of the installation rod. An installation opening is provided on the positioning member. The end of the installation rod is inserted into the installation opening. A plurality of positioning feet are connected to the lower part of the positioning member.

[0010] Further, a second positioning seat is connected to the upper part of one end of the second operation surface away from the first operation surface. A positioning groove matching with the positioning feet is provided on the second positioning seat. A slot is provided on the upper part of one end of the first operation surface away from the second operation surface.

[0011] Further, a positioning frame is further included. The positioning frame is arranged along the outer periphery of the mold. At least one side on the outer side of the mold is connected to the positioning frame. First positioning seats are provided on both sides of the positioning frame. A plurality of positioning grooves matching with the positioning feet are provided on the first positioning seat.

[0012] A method for batch laying solar cells on the wing of a solar fixed-wing unmanned aerial vehicle includes the following steps:

[0013] Based on the first installation surface and the second installation surface on the mold, a profiling tooling is made. The shapes of the first operation surface and the second operation surface on the profiling tooling are respectively the same as those of the first installation surface and the second installation surface. Solar cells are placed at preset positions on the first operation surface and the second operation surface. Welding tapes are welded between adjacent solar cells to connect a plurality of single solar cells into a battery cell group.

[0014] The transfer tooling moves above the profiling tooling. The solar cells are adsorbed by the adsorption mechanism on the transfer tooling. The transfer tooling is moved from the profiling tooling to the mold. The solar cells are placed on the first installation surface and the second installation surface of the mold.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 - 7 shown, a detection device for the production of a circular knitting machine cylinder includes a mold 1 and a profiling tooling. The upper part of the mold 1 is provided with a connected first mounting surface 2 and a second mounting surface 3. The second mounting surface 3 is inclined. One end of the second mounting surface 3 connected to the first mounting surface 2 is higher than the end of the second mounting surface 3 away from the first mounting surface 2. The profiling tooling includes a first operation surface 7 and a second operation surface 8. The first operation surface 7 has the same shape as the first mounting surface 2, and the second operation surface 8 has the same shape as the second mounting surface 3.

[0028] Moreover, the inclination angle of the operating surface II 8 is the same as that of the mounting surface II 3. The operating surface I 7 and the operating surface II 8 are exact or approximate replicas of the mounting surface I 2 and the mounting surface II 3. Placing the solar cell 20 on the operating surface I 7 and the operating surface II 8 of the profiling tooling for welding is equivalent to placing the solar cell 20 on the mounting surface I 2 and the mounting surface II 3 of the mold 1 for welding, ensuring the consistency and accuracy of the position of the solar cell 20.

[0029] A support base 9 is provided at the lower part of the profiling tooling. It further includes a transfer tooling, and the transfer tooling includes a mounting rod 12, and a number of adsorption mechanisms 6 are mounted on the mounting rod 12.

[0030] After the welding between the solar cells 20 is completed on the profiling tooling, the battery cell group is adsorbed and transferred to the mold 1 through the transfer tooling, which can avoid damaging the surface of the high-precision mold 1 during welding.

[0031] The solar cells 20 are neatly arranged in a predetermined position on the profiling tooling. It can be achieved by making marks on the operating surface I 7 and the operating surface II 8 according to the preset positions of the solar cells, or by numerically controlled automatic alignment.

[0032] Furthermore, the adsorption mechanism 6 includes a mounting block 15, the mounting block 15 is mounted on the mounting rod 12, a suction cup 18 is mounted at the lower part of the mounting block 15, and the axis of the suction cup 18 is perpendicular to the upper end surface of the solar cell 20 to be adsorbed, so as to ensure that the suction cup 18 can fully contact the upper end surface of the solar cell 20 and can better perform adsorption. A pipeline 19 is connected to the suction cup 18, the pipeline 19 is arranged through the mounting block 15, and a vacuum pump can be connected to the pipeline 19. The vacuum pump can generate negative pressure at the suction cup 18 to adsorb the solar cell 20.

[0033] Furthermore, a fixing block 16 is connected to the upper part of the mounting block 15, a fixing hole 17 is provided on the fixing block 16, a mounting groove 14 is provided on one side of the mounting rod 12 facing the fixing block 16, the mounting groove 14 is arranged along the length direction of the mounting rod 12, and a bolt is connected between the fixing block 16 and the mounting rod 12, and the bolt passes through the fixing hole 17 and is screwed into the mounting groove 14. The position of the fixing block 16 mounted on the mounting rod 12 can be adjusted so that the suction cup 18 can be adapted to the position of the corresponding solar cell 20.

[0034] Further, positioning members 13 are installed at both ends of the installation rod 12. An installation opening 21 is formed in the positioning member 13. The end of the installation rod 12 is inserted into the installation opening 21. A plurality of positioning feet 22 are connected to the lower part of the positioning member 13. The upper part of one end of the operation surface two 8 away from the operation surface one 7 is connected with a second positioning seat 11. A positioning groove matching with the positioning feet 22 is formed in the second positioning seat 11. A slot 23 is formed in the upper part of one end of the operation surface one 7 away from the operation surface two 8. The positioning member 13 can be matched with the second positioning seat 11 and the slot 23 on the profiling tooling for positioning.

[0035] It further includes a positioning frame 4. The positioning frame 4 is arranged along the outer periphery of the mold 1. At least one side on the outer side of the mold 1 is connected with the positioning frame 4. First positioning seats 5 are arranged on both sides of the positioning frame 4. A plurality of positioning grooves matching with the positioning feet 22 are arranged on the first positioning seats 5. The positions of the first positioning seats 5 on the positioning frame 4 correspond to the positions of the second positioning seat 11 and the slot 23 on the profiling tooling, so that after the transfer tooling is moved from the profiling tooling to the mold, the placement positions are the same, thereby ensuring that the placement positions of the solar cells 20 on the profiling tooling and the mold are the same.

[0036] The profiling tooling is made of aluminum profiles. The connection part of the operation surface one 7 and the operation surface two 8, that is, the connection part of two aluminum profiles, uses a connection seat 10 to fix the segmented aluminum profiles below this connection part.

[0037] The mold 1 is a surface female mold based on the skin. The profiling tooling is made based on the first installation surface 2 and the second installation surface 3 on the mold 1. The shapes of the operation surface one 7 and the operation surface two 8 on the profiling tooling are respectively consistent with those of the first installation surface 2 and the second installation surface 3. The solar cells 20 are placed at preset positions on the operation surface one 7 and the operation surface two 8. Welding tapes are welded between adjacent solar cells 20 to connect a plurality of single solar cells 20 into a battery cell group. Welding can use a mature automatic welding machine. Using a numerical control computer, the welding tapes can be accurately welded to the electrodes of the solar cells, thus eliminating the manual welding link.

[0038] The transfer tooling can be moved above the profiling tooling manually or by a robotic arm. The solar cells 20 are adsorbed by the adsorption mechanism 6 on the transfer tooling. Each solar cell 20 has a corresponding adsorption mechanism 6 for adsorption. The transfer tooling is moved from the profiling tooling to the mold 1. The solar cells 20 are placed on the first installation surface 2 and the second installation surface 3 of the mold 1. The adsorption of the adsorption mechanism on the adsorption mechanism 6 stops, and the solar cells 20 fall on the mold 1 to complete the laying.

[0039] The transfer tooling is moved to the profiling tooling, and one end is positioned by the cooperation of the positioning part 13 and the second positioning seat 11, and the other end is positioned by the cooperation of the positioning part 13 and the slot 23. The transfer tooling is moved to the mold, and positioning is formed by the cooperation of the positioning parts 13 at both ends and the two first positioning seats 5. The transfer tooling is positioned and installed on the profiling tooling or the mold 1, so that the installation position of the solar cell 20 on the mold 1 can be consistent with that on the profiling tooling.

[0040] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
