[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] In a first aspect, an embodiment of the utility model provides a suction cup structure, Figure 2 This is a top view of a suction cup structure of an embodiment of the utility model. Figure 3 2 is a top view of another suction cup structure of an embodiment of the present utility model, as shown in FIG. Figure 1 , Figure 2 and Figure 3 As shown, the suction cup structure includes:

[0036] A suction cup body 1, a suction nozzle 2 arranged on the suction cup body 1, and an airway arranged in the inner cavity of the suction cup body 1, wherein the airway and the suction nozzle 2 are in communication;

[0037] The inner cavity of the suction cup body 1 includes a circumferential inner cavity 11, a transverse inner cavity 12 and a longitudinal inner cavity 13, and the air channel includes a circumferential air channel 3, a transverse air channel 4 and a longitudinal air channel 5. The transverse inner cavity 12 and the longitudinal inner cavity 13 are arranged at an intersection, the transverse air channel 4 is arranged in the transverse inner cavity 12, the longitudinal air channel 5 is arranged in the longitudinal inner cavity 13, and the circumferential air channel 3 is arranged in the circumferential inner cavity 11.

[0038] At least a portion of the circumferential inner cavity 11 intersects with the transverse inner cavity 12 and the longitudinal inner cavity 13 at the same time.

[0039] Suction nozzles 2 are provided on the suction cup body 1 corresponding to the circumferential inner cavity 11 , the transverse inner cavity 12 and the longitudinal inner cavity 13 .

[0040] It can be seen from the above embodiments that in the embodiments of the utility model, the transverse inner cavity 12 and the longitudinal inner cavity 13 are arranged to intersect, and at least part of the circumferential inner cavity 11 intersects with the transverse inner cavity 12 and the longitudinal inner cavity 13 at the same time, and the suction cup body 1 corresponding to the circumferential inner cavity 11, the transverse inner cavity 12 and the longitudinal inner cavity 13 is provided with a suction nozzle 2. In this way, the suction cup body 1 corresponding to the circumferential inner cavity 11 can provide a position for setting the suction nozzle 2, increase the suction points, and thus achieve the purpose of improving the suction force of the suction cup structure. At the same time, the suction cup body 1 of the circumferential inner cavity increases the installation area of ​​the suction nozzle 2, which is conducive to the uniform distribution of the suction nozzle 2, and provides conditions for the adsorbed object to obtain a uniformly distributed adsorption force.

[0041] It should be noted that the transverse inner cavity 12 and the longitudinal inner cavity 13 in the embodiment of the utility model are arranged to intersect, that is, a mesh structure is formed between the suction cup body 1 corresponding to the transverse inner cavity 12 and the suction cup body 1 corresponding to the longitudinal inner cavity 13. The angle at which the transverse inner cavity 12 and the longitudinal inner cavity 13 intersect can be an acute angle or a right angle, and the embodiment of the utility model does not limit this. The suction cup body 1 constituting the transverse inner cavity 12 and the longitudinal inner cavity 13 can include a plurality of hollow beam-like structures with rectangular cross-sections, and has a cross gas channel at the intersection of the transverse inner cavity 12 and the longitudinal inner cavity 13. The number of transverse inner cavities 12 and the number of longitudinal inner cavities 13 can be equal or unequal, such as the number of transverse inner cavities 12 is 4, the number of longitudinal inner cavities 13 is 4, the number of transverse inner cavities 12 is 4, the number of longitudinal inner cavities 13 is 5, the number of transverse inner cavities 12 is 5, and the number of longitudinal inner cavities 13 is 5, and the embodiment of the utility model does not limit this.

[0042] like Figure 4 and Figure 5 As shown, the transverse airway 4 can be understood as a tube or other shaped airway arranged in the transverse inner cavity 12 and extending in the transverse direction, that is, the flow direction of the airflow in the transverse airway 4 is transverse, and the longitudinal airway 5 can also be understood as a tube or other shaped airway arranged in the transverse inner cavity 12 and extending in the longitudinal direction, that is, the flow direction of the airflow in the longitudinal airway 5 is longitudinal. Figure 2 The direction shown by X in the figure is vertical. Figure 1In the direction shown by Y in FIG. In addition, it should be noted that the circumferential airway 3, the transverse airway 4 and the longitudinal airway 5 can be three independent airways, that is, the gas flow direction in the circumferential airway 3, the gas flow direction in the transverse airway 4 and the gas flow direction in the longitudinal airway 5 do not interfere with each other, or, the transverse airway 4 and the longitudinal airway 5 are intertwined airways, and the circumferential airway 3 is an independent airway, that is, the flow direction of the transverse airway 4 and the gas in the longitudinal airway 5 intersect and flow, the flow direction of the transverse airway 4 and the gas in the longitudinal airway 5 intersect and flow, and the gas in the circumferential airway 3 flows independently. The specific structural types of the circumferential airway 3, the transverse airway 4 and the longitudinal airway 5 are determined according to the processing technology of the airway, and the embodiments of the utility model do not limit this.

[0043] Based on the intersection of the transverse inner cavity 12 and the longitudinal inner cavity 13, there must be a blank area (an area where the suction cup body 1 is not set) between the transverse inner cavity 12 and the longitudinal inner cavity 13. Exemplarily, when the angle between the transverse inner cavity 12 and the longitudinal inner cavity 13 is a right angle, the blank area surrounded by the orthographic projection of the suction cup body 1 corresponding to the transverse inner cavity 12 and the orthographic projection of the suction cup body 1 corresponding to the longitudinal inner cavity 13 is a rectangular area. In this way, the suction nozzle 2 cannot be set in the blank area surrounded by the orthographic projection of the suction cup body 1 corresponding to the transverse inner cavity 12 and the orthographic projection of the suction cup body 1 corresponding to the longitudinal inner cavity 13, and there will be a position where the adsorbed part has no adsorption force, which is not conducive to the uniform distribution of the suction nozzle 2.

[0044] Based on this, in the embodiment of the utility model, in addition to the transverse inner cavity 12 and the longitudinal inner cavity 13, a circumferential inner cavity 11 is also provided. The structure of the suction cup body 1 corresponding to the circumferential inner cavity 11 can be a circular ring structure, or a diamond frame structure, or a rectangular frame structure, or other closed graphic structures, which is not limited in the embodiment of the utility model. The flow direction of the airflow in the circumferential airway 3 provided in the circumferential inner cavity 11 is the circumference of the suction cup body 1. At least part of the circumferential inner cavity 11 intersects with the transverse inner cavity 12 and the longitudinal inner cavity 13 at the same time, which will inevitably make part of the position of the circumferential inner cavity 11 neither located in the extension direction of the transverse inner cavity 12 nor located in the extension direction of the longitudinal inner cavity 13. That is, it is inevitable that part of the suction cup body 1 corresponding to the circumferential inner cavity 11 is located in the empty area surrounded by the positive projection of the suction cup body 1 corresponding to the transverse inner cavity 12 and the positive projection of the suction cup body 1 corresponding to the longitudinal inner cavity 13, and then the suction point can be increased by setting the suction nozzle 2 here to improve the suction force of the suction cup structure.

[0045] Next, the specific setting position of the suction nozzle 2 in the embodiment of the utility model and the structural composition of the circumferential inner cavity 11, the structural composition of the transverse inner cavity 12 and the structural composition of the longitudinal inner cavity 13 are specifically introduced as follows:

[0046] Regarding the specific setting position of the suction nozzle 2, in some embodiments, the suction nozzle 2 includes multiple first suction ports 21, multiple second suction ports 22 and multiple third suction ports 23; the position on the suction cup body 1 corresponding to the intersection of the transverse inner cavity 12 and the longitudinal inner cavity 13 is the first position, the position on the suction cup body 1 corresponding to the intersection of the transverse inner cavity 12, the longitudinal inner cavity 13 and the circumferential inner cavity 11 is the second position, and the suction cup body 1 corresponding to the orthographic projection of the suction cup body 1 corresponding to the blank area of ​​the suction cup body 1 corresponding to the transverse inner cavity 12 and the longitudinal inner cavity 13 and the orthographic projection of the circumferential inner cavity 11 is the third position; the first suction port 21 is set at the first position, the second suction port 22 is set at the second position, and the third suction port 23 is set at the third position.

[0047] It should be noted that, in this embodiment, since the first suction port 21 is set at the first position, on the corresponding suction cup body 1, the first suction port 21 is a common air port for the transverse inner cavity 12 and the longitudinal inner cavity 13. Since the second suction port 22 is set at the second position, the position on the suction cup body 1 corresponding to the intersection of the transverse inner cavity 12, the longitudinal inner cavity 13 and the circumferential inner cavity 11 is the second position, so the second suction port 22 is a common air port for the transverse inner cavity 12, the longitudinal inner cavity 13 and the circumferential inner cavity 11.

[0048] The three suction ports 23 are set at the third position, and the third position is on the suction cup body 1 corresponding to the overlap of the positive projection of the horizontal inner cavity 12 and the empty area of ​​the suction cup body 1 corresponding to the longitudinal inner cavity 13, and the positive projection of the circumferential inner cavity 11, so the third air port is the only air port of the circumferential inner cavity 11. Based on this, in the embodiment of the utility model, the adsorbed object can be adsorbed not only through the first suction port 21 and the second suction port 22, but also through the third suction port 23. In this way, since the third suction port 23 is set at the third position, the suction cup body 1 corresponding to the overlap of the orthographic projection of the empty area surrounded by the transverse inner cavity 12 and the longitudinal inner cavity 13 and the orthographic projection of the circumferential inner cavity 11 is the third position. Therefore, the area on the suction cup body 1 corresponding to the intersection of the circumferential inner cavity 11 and the transverse inner cavity 12 and the longitudinal inner cavity 13, that is, the empty area surrounded by the orthographic projection of the suction cup body 1 corresponding to the transverse inner cavity 12 and the orthographic projection of the suction cup body 1 corresponding to the longitudinal inner cavity 13, can also be installed with the suction nozzle 2 to adsorb the object to be adsorbed, thereby making the distribution of the suction nozzle 2 more uniform, which is further conducive to the uniform distribution of the suction nozzle 2. Among them, the first position is as Figure 2 As shown in W1 in the figure, the second position is as follows Figure 2 As shown in W2 in the figure, the second position is Figure 2 As shown in W3.

[0049] In addition, the first suction port 21, the second suction port 22 and the third suction port 23 can be vacuum suction cups of any shape such as round, rectangular, square, oval, flat, V-shaped, corrugated, etc. The material of the first suction port 21, the material of the second suction port 22 and the material of the third suction port 23 can be any material such as synthetic rubber, silicone, chloroprene rubber, polyurethane, rubber, polytetrafluoroethylene, glass, ceramic, metal, etc., and the embodiment of the utility model is not limited to this.

[0050] Regarding the size structure of the third suction port 23 in the above embodiment, in some embodiments, the first suction port 21, the second suction port 22 and the third suction port 23 are all disc-shaped suction ports, wherein the first suction port 21 is located away from the center of the suction cup body 1, and the third suction port 23 is located close to the center of the suction cup body 1, and the diameter of the third suction port 23 is smaller than the diameter of the first suction port 21.

[0051] It should be noted that, in vacuum suction, the larger the aperture, the smaller the suction, and the smaller the aperture, the greater the suction, that is, the suction of the suction port is inversely proportional to the diameter of the suction port. Therefore, when the first suction port 21 is located away from the center of the suction cup body 1, the third suction port 23 is located near the center of the suction cup body 1, and the diameter of the third suction port 23 is smaller than the diameter of the first suction port 21, the suction at the position away from the center of the suction cup body 1 can be smaller than the suction at the position near the center of the suction cup body 1, thereby making the suction of the suction cup structure more in line with the physical requirement of adsorption that the center requires greater adsorption force than the edge position, further improving the adsorption force of the suction cup structure. The diameter specifications of the first suction port 21, the diameter specifications of the second suction port 22, and the diameter specifications of the third suction port 23 can all be 0.6mm to 1mm, 1.2mm to 1.5mm, and 3mm to 3.6mm. For example, when the first suction port 21 is 3mm, the third suction port 23 can be 1.5mm, 1.3mm, 1.2mm, and 1mm.

[0052] Furthermore, the suction force of the third suction port 23 is greater than the suction force of the first suction port 21, and the difference between the suction force of the third suction port 23 and the suction force of the first suction port 21 is between 0.2 Pa and 0.5 Pa. In this way, since the first suction port 21 is located far away from the center of the suction cup body 1, and the third suction port 23 is located near the center of the suction cup body 1, it can be ensured that the suction force generated by the single first suction port 21 at a position far away from the center of the suction cup body 1 is smaller than the suction force of the single third suction port 23 at a position near the center of the suction cup body 1, ensuring that the suction force of the suction cup structure better meets the physical requirement of adsorption that the adsorption force required at the center is greater than that at the edge.

[0053] Regarding the structural composition of the transverse inner cavity 12 and the structural composition of the longitudinal inner cavity 13, in some embodiments, the spacing between every two adjacent transverse inner cavities 12 is equal, and the spacing between every two adjacent longitudinal inner cavities 13 is equal.

[0054] It should be noted that, since the spacing between each two adjacent transverse cavities 12 is equal, the distance between adjacent first suction ports 21 and second suction ports 22 is equal in the transverse direction. Since the spacing between each two adjacent longitudinal cavities 13 is equal, the distance between adjacent first suction ports 21 and second suction ports 22 is equal in the longitudinal direction, so that the spacing between the suction nozzles 2 corresponding to the two adjacent first suction ports 21 and second suction ports 22 arranged in the longitudinal direction is equal, that is, the suction nozzles 2 corresponding to the two adjacent first suction ports 21 and second suction ports 22 arranged in the longitudinal direction can be evenly distributed, so that the adsorption force on the adsorbed part in the longitudinal direction can be evenly distributed, so that the spacing between the suction nozzles 2 corresponding to the two adjacent first suction ports 21 and second suction ports 22 arranged in the transverse direction is equal, that is, the suction nozzles 2 corresponding to the two adjacent first suction ports 21 and second suction ports 22 arranged in the transverse direction can be evenly distributed, so that the adsorption force on the adsorbed part in the transverse direction can be evenly distributed. In addition, if the spacing between each two adjacent transverse inner cavities 12 is equal to the spacing between each two adjacent longitudinal inner cavities 13, the suction nozzles 2 corresponding to each two adjacent first suction ports 21 and the second suction ports 22 and the suction nozzles 2 corresponding to each two adjacent second suction ports 22 can be evenly distributed in the transverse and longitudinal directions, which is beneficial to the uniform distribution of the suction nozzles 2.

[0055] As for the structural composition of the circumferential inner cavity 11, the number of the circumferential inner cavity 11 is at least two, and the shape of the orthographic projection of at least two circumferential inner cavities 11 is a concentric ring. In this way, the diameters of two adjacent circumferential inner cavities 11 in the plurality of circumferential inner cavities 11 can be increased successively along the direction from the center of the suction cup body 1 to the edge of the suction cup body 1, so that the area of ​​the orthographic projection of the circumferential inner cavity 11 can also be increased successively along the direction from the center of the suction cup body 1 to the edge of the suction cup body 1, and thus the area of ​​the circumferential inner cavity 11 where the suction nozzle 2 can be installed can be increased successively, that is, the number of suction nozzles 2 that can be installed on the circumferential inner cavity 11 also increases successively, which is more conducive to the uniform distribution of the suction nozzles 2.

[0056] Optionally, along the direction from the center of the suction cup body 1 to the edge of the suction cup body 1, the difference in diameter between two adjacent circumferential inner cavities 11 among the plurality of circumferential inner cavities 11 is in an arithmetic progression or a geometric progression. In this way, in the same radial direction (in the direction from the center of the suction cup body 1 to the edge of the suction cup body 1), the spacing between each two adjacent third suction ports 23 is equal, so that the suction nozzles 2 in the empty area surrounded by the transverse inner cavity 12 and the longitudinal inner cavity 13 can also be evenly distributed, thereby making the distribution of the suction nozzles 2 more even.

[0057] Optionally, in some embodiments, the gas flow direction in the circumferential air channel 3 and the gas flow direction in the transverse air channel 4 do not interfere with each other, and the gas flow direction in the circumferential air channel 3 and the gas flow direction in the longitudinal air channel 5 do not interfere with each other.

[0058] In this embodiment, since the gas flow direction in the circumferential air channel 3 and the gas flow direction in the transverse air channel 4 do not interfere with each other, and the gas flow direction in the circumferential air channel 3 and the gas flow direction in the longitudinal air channel 5 do not interfere with each other, the air path in the circumferential air channel 3 and the air path in the transverse air channel 4 are independent of each other, and the air path in the circumferential air channel 3 and the air path in the longitudinal air channel 5 are independent of each other, thereby ensuring the adsorption effect of each suction nozzle 2 at the same time. Exemplarily, in some embodiments, the third suction port 23 can be adsorbed more than 200 milliseconds before the first suction port 21 and the second suction port 22, thereby ensuring that the gas flow direction in the circumferential air channel 3 and the gas flow direction in the transverse air channel 4 do not interfere with each other, and the gas flow direction in the circumferential air channel 3 and the gas flow direction in the longitudinal air channel 5 do not interfere with each other. Among them, the gas flow direction in the circumferential air channel 3 is as follows: Figure 4 The gas flow direction in the transverse airway 412 is as shown in C. Figure 4 The flow direction shown in A in FIG. 1 and the gas flow direction in the longitudinal airway 5 are as follows: Figure 4 The flow direction is shown in B.

[0059] Regarding the overall structure of the suction cup body 1 , in some feasible embodiments, the center of the orthographic projection of the maximum area enclosed by the transverse inner cavity 12 and the longitudinal inner cavity 13 coincides with the center of the orthographic projection of the circumferential inner cavity 11 .

[0060] In this embodiment, when the center of the orthographic projection of the largest area enclosed by the transverse inner cavity 12 and the longitudinal inner cavity 13 coincides with the center of the orthographic projection of the circumferential inner cavity 11, the overall structure of the suction cup body 1 is a relatively square block structure, so that at the same volume, the suction cup body 1 can have a larger surface area for installing the suction nozzle 2, and the suction cup body 1 can be easily processed and manufactured.

[0061] It can be seen from the above embodiments that in the embodiments of the utility model, the transverse inner cavity 12 and the longitudinal inner cavity 13 are arranged to intersect, and at least part of the circumferential inner cavity 11 intersects with the transverse inner cavity 12 and the longitudinal inner cavity 13 at the same time, and the suction cup body 1 corresponding to the circumferential inner cavity 11, the transverse inner cavity 12 and the longitudinal inner cavity 13 is provided with a suction nozzle 2. In this way, the suction cup body 1 corresponding to the circumferential inner cavity 11 can provide a position for setting the suction nozzle 2, increase the suction points, and thus achieve the purpose of improving the suction force of the suction cup structure. At the same time, the suction cup body 1 with the circumferential inner cavity distributed in concentric circles is conducive to the uniform distribution of the suction nozzle 2, providing conditions for the adsorbed object to obtain a uniformly distributed adsorption force.

[0062] In the second aspect, the embodiment of the utility model provides a photovoltaic manufacturing system, wherein the photovoltaic manufacturing system has the suction cup structure described in any of the above embodiments, and the photovoltaic manufacturing system is used to prepare photovoltaic photovoltaic cell sheets, and the photovoltaic photovoltaic cell sheets are adsorbed and connected to the suction cup structure. In this way, in the photovoltaic manufacturing system, when the photovoltaic cell sheet is adsorbed by the suction cup structure, since the suction cup body 1 corresponding to the circumferential inner cavity 11 can provide a position for setting the suction nozzle 2, the adsorption points are increased, thereby achieving the purpose of improving the adsorption force of the suction cup structure, and at the same time, the suction cup body 1 corresponding to the circumferential inner cavity 11 can provide a position for setting the suction nozzle 2, and the adsorption points are increased, thereby achieving the purpose of improving the adsorption force of the suction cup structure, in this way, in the process of adsorbing the photovoltaic cell sheet, the adsorption force on the photovoltaic cell sheet can be evenly distributed, thereby not causing deformation of the photovoltaic cell sheet due to insufficient or uneven distribution of adsorption force, thereby ensuring the accuracy of the photovoltaic cell sheet manufacturing process.

[0063] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] Although the preferred embodiments of the utility model embodiments have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the utility model embodiments.

[0065] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.
