[0028] In the description of the present invention, "plurality" means two or more.

[0029] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0030] The suction cup 1 for a photovoltaic cell sheet according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 4 As shown, the suction cup 1 for a photovoltaic cell according to an embodiment of the utility model comprises: an adsorption body 100 and a valve core 200 .

[0032] The adsorption body 100 is configured with a main adsorption port 101 connected to a gas source and an attachment surface 102 for attaching a photovoltaic cell. The attachment surface 102 is formed with an adsorption flow channel 103 extending radially from the center to the outside. The gas flowing along the adsorption flow channel 103 is suitable for adsorbing the photovoltaic cell 10. The valve core 200 is installed at the center of the adsorption body 100. The valve core 200 is configured with a valve channel 201, which is connected to the main adsorption port 101 and the adsorption flow channel 103.

[0033] For example, the suction cup 1 is specifically a Bernoulli suction cup, and the main suction port 101 is used to supply air to the adsorption channel 103, so that the airflow flows along the adsorption channel 103. Using the Bernoulli principle, the greater the airflow velocity, the smaller the pressure, and the photovoltaic cell 10 is adsorbed on the attachment surface 102. Among them, the attachment surface 102 of the suction cup 1 is configured as a rectangle or a square, and the photovoltaic cell 10 is adapted to the shape of the attachment surface 102. The main suction port 101 is located at the center of the suction cup 1. The main suction port 101 faces the top of the suction cup 1, and the main suction port 101 is connected to the attachment surface 102 at the bottom of the adsorption body 100 through the valve core 200. The valve core 200 is installed at the center of the inside or bottom of the adsorption body 100, and the radially extending adsorption channel 103 is connected to the valve channel 201 in the central area, so that the gas released from the main suction port 101 flows from the center of the attachment surface 102 along the adsorption channel 103 to the outside of the attachment surface 102. For example, the adsorption channel 103 forms a “M” shape, and the adsorption channel 103 extends from the main adsorption port 101 to each side and each corner of the attachment surface 102 .

[0034] According to the suction cup 1 for photovoltaic cells of the embodiment of the utility model, the suction flow channel 103 extending radially from the center to the outside is constructed by the suction body 100, and multiple radial line suction areas or even surface suction areas are formed on the attachment surface 102. Compared with the suction cup of "point suction", the suction force can be more evenly distributed in various areas of the suction cup 1, increasing the suction area, and the suction area is more dispersed, the photovoltaic cell 10 can be stressed as a whole, and the stress on the four corners of the photovoltaic cell 10 is reduced. Furthermore, by increasing the suction area of ​​the suction flow channel 103, not only can the photovoltaic cell 10 be prevented from being damaged, but also the adsorption stability of the photovoltaic cell 10 can be improved, and the photovoltaic cell 10 can be kept in an accurate adsorption position with the attachment surface 102 to prevent the photovoltaic cell 10 from shifting or falling.

[0035] Moreover, the radially extending adsorption channel 103 can guide the airflow, and the width of the adsorption channel 103 is relatively narrow, so that the airflow passes quickly in the adsorption channel 103, thereby further increasing the speed of the airflow, improving the utilization rate of the gas, and reducing the gas consumption. In addition, by forming a linear adsorption area or a surface adsorption area, the contact area between the attachment surface 102 of the suction cup body and the photovoltaic cell 10 is reduced, thereby reducing the probability of static electricity.

[0036] Therefore, the suction cup 1 for the photovoltaic cell sheet according to the embodiment of the utility model has the advantages of uniform and stable adsorption force, low gas consumption, good protection for the photovoltaic cell sheet 10, etc.

[0037] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the adsorption channel 103 includes: a transverse channel 11 and a longitudinal channel 12, a first diagonal channel 13 and a second diagonal channel 14. The transverse channel 11 and the longitudinal channel 12 extend perpendicularly to each other, and the two ends of the transverse channel 11 extend to two opposite sides of the adsorption body 100, and the two ends of the longitudinal channel 12 extend to the other two opposite sides of the adsorption body 100. The two ends of the first diagonal channel 13 extend to the two opposite corners of the adsorption body 100, and the two ends of the second diagonal channel 14 extend to the other two opposite corners of the adsorption body 100.

[0038] The attachment surface 102 is configured in a rectangular or square shape, the transverse flow channel 11, the longitudinal flow channel 12, the first diagonal flow channel 13 and the second diagonal flow channel 14 are all connected to each other, the gas flowing out of the valve channel 201 flows outward along the transverse flow channel 11, the longitudinal flow channel 12, the first diagonal flow channel 13 and the second diagonal flow channel 14 respectively, the shape of the photovoltaic cell 10 matches the shape of the attachment surface 102, the middle and edge of the photovoltaic cell 10 are all airflow passing through, and the four sides and four corners of the photovoltaic cell 10 are also airflow passing through, so that the suction cup 1 has a uniform adsorption effect on the photovoltaic cell 10. In addition, the adsorption flow channel 103 forms a radial line adsorption or surface adsorption area, and the adsorption force will not be concentrated on the four corners of the photovoltaic cell 10, thereby reducing the possibility of damage to the four corners.

[0039] Furthermore, if Figure 2 As shown, the adsorption channel 103 also includes an annular channel 15, which surrounds the valve core 200, the valve channel 201 is connected to the annular channel 15, and the transverse channel 11, the longitudinal channel 12, the first diagonal channel 13 and the second diagonal channel 14 are all connected to the annular channel 15.

[0040] The adsorption channel 103 forms an annular channel 15 to better guide the flow of air from the suction cup 1. The airflow flowing out of the valve core 200 from the valve channel 201 can be more easily dispersed to the lateral channel 11, the longitudinal channel 12, the first diagonal channel 13 and the second diagonal channel 14 through the annular channel 15. The airflow flows more smoothly, and the airflow velocity flowing to the lateral channel 11, the longitudinal channel 12, the first diagonal channel 13 and the second diagonal channel 14 is faster, thereby reducing gas consumption while ensuring strong adsorption force.

[0041] Furthermore, if Figure 4 As shown, the adsorption body 100 is constructed with a receiving groove 104 connected to the main adsorption port 101 at the center of the side facing the attachment surface 102, the valve core 200 covers the receiving groove 104, and the radial outer side of the receiving groove 104 is connected to an annular groove, which forms an annular flow channel 15.

[0042] The valve core 200 covers the notch of the receiving groove 104 to form a relatively closed cavity, which can accommodate more gas. The airflow is more easily dispersed to the annular flow channel 15 along the edge of the receiving groove 104, and then further flows to the transverse flow channel 11, the longitudinal flow channel 12, the first diagonal flow channel 13 and the second diagonal flow channel 14.

[0043] Furthermore, if Figure 4As shown, the bottom surface of the valve core 200 is flush with the attachment surface 102. As a result, the bottom surface of the entire suction cup 1 is in the same plane, and the photovoltaic cell 10 is supported by the bottom surface of the valve core 200 and the bottom surface of the adsorption body 100. The force at each position of the photovoltaic cell 10 is kept consistent, preventing the photovoltaic cell 10 from being damaged during adsorption.

[0044] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the suction cup 1 also includes a gasket 300, for example, the gasket 300 is specifically a silicone pad. The gasket 300 is attached to the attachment surface 102 and the bottom surface of the valve core 200. The gasket 300 is separated by a spacer, and the spacer extends radially from the center to the outside. The spacer defines the adsorption flow channel 103 on the attachment surface 102. In this way, the attachment surface 102 is relatively flat, and the supporting effect on the photovoltaic cell 10 is better.

[0045] In some embodiments, the attachment surface 102 forms a plane, and the spacer formed by the gasket 300 has a certain thickness. The gasket 300 defines the adsorption flow channel 103 on the attachment surface 102. When the gasket 300 is attached to the photovoltaic cell 10, a certain gap is formed between the photovoltaic cell 10 and the attachment surface 102 at the spacer, so that the airflow flows through the adsorption flow channel 103 formed by the spacer between the gaskets 300. The gasket 300 is a flexible member, which can play a certain buffering and protective role on the photovoltaic cell 10 to prevent the photovoltaic cell 10 from being damaged by bumps, and the gasket 300 is soft in texture, and has a better bonding effect when the suction cup 1 adsorbs the photovoltaic cell 10.

[0046] Furthermore, in some other embodiments, a radial groove structure may be constructed on the attachment surface 102 to form an adsorption channel 103 , which can also allow air flow to pass through, thereby adsorbing the photovoltaic cell 10 .

[0047] Furthermore, if Figure 2 As shown, the bottom surface of the gasket 300 is constructed with a protruding wire mesh structure. When the suction cup 1 is adsorbed, the wire mesh structure fits with the photovoltaic cell 10, and the bottom surface of the gasket 300 does not need to be completely in contact with the photovoltaic cell 10, which reduces the contact area between the gasket 300 and the photovoltaic cell 10. Compared with a smooth surface, the wire mesh structure has a reduced contact area with the cell, which can be reduced by about 25%. In addition, the wire mesh structure can be easily compressed and deformed, and has a good vibration absorption effect.

[0048] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, the valve channel 201 includes: a transverse valve channel 202 and a longitudinal valve channel 203. The transverse valve channel 202 penetrates the valve core 200 in the radial direction, and the two ends of the transverse valve channel 202 correspond to the positions of the transverse flow channel 11. The longitudinal valve channel 203 penetrates the valve core 200 in the radial direction, and the two ends of the longitudinal valve channel 203 correspond to the positions of the longitudinal flow channel 12.

[0049] For example, the valve core 200 is configured as a thin cylindrical structure, and the valve core 200 is configured with a bottom wall and a surrounding portion, and the surrounding portion is formed with a notch to form a transverse valve channel 202 and a longitudinal valve channel 203. The central area of ​​the valve core 200 is connected to the receiving groove 104, and the gas first flows into the receiving groove 104 from the main adsorption port 101, and then flows out of the valve core 200 through the transverse valve channel 202 and the longitudinal valve channel 203 after passing through the central area of ​​the valve core 200. A part of the gas flowing out of the valve core 200 flows along the transverse flow channel 11 and the longitudinal flow channel 12, and the other part flows along the annular flow channel 15 to the first diagonal flow channel 13 and the second diagonal flow channel 14.

[0050] Thus, the gas flowing in the transverse flow channel 11 and the longitudinal flow channel 12 can provide a greater adsorption force to form a "cross"-shaped main adsorption area, and the gas flowing in the annular flow channel 15, the first diagonal flow channel 13, and the second diagonal flow channel 14 can provide auxiliary adsorption force to form an "X"-shaped auxiliary adsorption area. The main adsorption area and the auxiliary adsorption area are combined to form a more uniform adsorption area, which greatly disperses the area where the photovoltaic cell 10 is subjected to force and reduces the risk of damage to the photovoltaic cell 10.

[0051] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the adsorption body 100 is configured with a plurality of weight-reducing holes 105 penetrating along the thickness direction thereof, and the plurality of weight-reducing holes 105 are alternately arranged along the circumferential direction with the adsorption flow channels 103 extending radially.

[0052] For example, the weight-reducing holes 105 are configured in an oblong shape, and a plurality of weight-reducing holes 105 surround the adsorption body 100 and are located on both sides of the adsorption channel 103. The weight-reducing holes 105 are evenly distributed on the adsorption body 100. The suction cup body and the valve core 200 can both be aluminum alloy parts, and the weight distribution of the adsorption body 100 is more uniform.

[0053] The photovoltaic production equipment 2 according to the embodiment of the present utility model is described below.

[0054] like Figure 1 As shown, the photovoltaic production equipment 2 according to the embodiment of the utility model comprises: the suction cup 1 for photovoltaic cells according to the above embodiment of the utility model.
