[0036] In the process of manufacturing solar cell pieces, it is necessary to sinter the cell pieces by using a sintering device (such as a ceramic sintering furnace or a chain sintering furnace). After sintering is completed, a conveying device conveys the cell pieces to the next process. When the cell pieces are conveyed by the conveying device, a cooling device is used to blow air on the cell pieces to reduce the temperature of the cell pieces, so as to avoid that the cell pieces are burned when conveyed to the next process due to the excessively high temperature.

[0037] In the prior art, an eddy gas pipe is generally used as a cooling device to reduce the temperature of the cell pieces by using a direct blowing method. However, in the actual operation process, the air outlet range of the eddy gas pipe is extremely limited, and the cell pieces cannot be uniformly cooled on the whole surface, and the cooling effect is greatly reduced. In addition, in the blowing process, the air force received by each part of the cell pieces is difficult to balance, and the cell pieces are easily blown to pieces due to the unbalanced force. The above situation seriously reduces the production efficiency, and also causes the risk of jamming and fragments in the production process.

[0038] Please refer to Figure 1 andFigure 2 , Figure 1 Figure 1 is a structural schematic diagram of a battery piece manufacturing production line 1 according to an embodiment of the present application, in which Figure 1 the top plate 214 covers the opening between the first side plate 212 and the second side plate 213, Figure 2 Figure 2 is a sectional view of the battery piece manufacturing production line 1 along the A-A direction according to an embodiment of the present application, in which Figure 2 the top plate 214 is flipped and opens the opening between the first side plate 212 and the second side plate 213.

[0039] In order to alleviate the above problems, the applicant has designed a battery piece manufacturing production line 1 after in-depth research, which comprises a sintering device 10, a conveying device 20 and a cooling device 30. The conveying device 20 comprises a conveying body 21 and a conveying roller set 22, the conveying roller set 22 is arranged on the conveying body 21, and the conveying roller set 22 is used to receive and transmit the battery piece sintered by the sintering device 10. The cooling device 30 comprises an air knife 31, the air knife 31 is installed on the conveying body 21 and has an air outlet 311, the air outlet 311 is arranged towards the conveying roller set 22 and extends along the direction in which the battery piece is transmitted by the conveying roller set 22.

[0040] Specifically, the conveying roller set 22 comprises a plurality of conveying rollers 221, all the conveying rollers 221 are arranged in sequence and at intervals along a preset direction X, all the conveying rollers 221 cooperate and are used to receive the battery piece sent by the sintering device 10, and then drive the battery piece to convey along the preset direction X to the device for executing the next process. The preset direction X is the direction in which the battery piece is transmitted by the conveying roller set 22.

[0041] The cooling device 30 comprises the air knife 31 and a fan, the air knife 31 has an air cavity and an air outlet 311 communicating with the air cavity, the air outlet 311 is arranged towards the conveying roller set 22 and extends along the direction in which the battery piece is transmitted by the conveying roller set 22, that is, the air outlet 311 extends along the preset direction X. The fan inputs airflow into the air cavity by operation and blows the airflow from the air outlet 311 of the air knife 31 towards the battery piece.

[0042] By arranging the air outlet 311 of the air knife 31 to extend along the direction in which the battery piece is transmitted by the conveying roller set 22, the air knife 31 can blow air to the battery piece more uniformly in the conveying direction of the battery piece during the conveying process of the battery piece, so that the whole surface of the battery piece can be cooled more uniformly, and the cooling effect is good. In addition, during the air blowing process, the wind force on each part of the battery piece in its conveying direction is more balanced, and the battery piece is less likely to be blown to pieces due to uneven force, thereby improving the production efficiency, and the risk of jamming and fragmentation is less likely to occur, and the safety is high.

[0043] In some embodiments, the sintering device 10 comprises a sintering body 11 having a sintering channel 111 and a conveying roller set 12 arranged in the sintering channel 111 and used for conveying the battery sheet; the conveying body 21 has a conveying channel 211 communicating with the sintering channel 111, and the conveying roller set 22 and the air knife 31 are arranged in the conveying channel 211.

[0044] For example, the sintering body 11 is connected with the conveying body 21, so that the sintering device 10 and the conveying device 20 are connected to form an integral whole, facilitating the installation of the two on the battery sheet manufacturing production line 1. Preferably, the sintering body 11 and the conveying body 21 are integrally arranged to facilitate molding.

[0045] The sintering body 11 has a sintering channel 111, and the conveying body 21 has a conveying channel 211, both of which extend along a predetermined direction X.

[0046] The conveying roller set 12 comprises a plurality of conveying rollers 121, all of which are arranged in sequence and at intervals along the predetermined direction X. All the conveying rollers 121 are cooperatively used to convey the battery sheet through the sintering channel 111, so that the battery sheet can be sintered in the sintering channel 111. All the conveying rollers 221 are cooperatively used to receive and convey the battery sheet sent by the conveying roller set 12.

[0047] Among them, the conveying roller 121 and the conveying roller 221 are conventional technical means in the art, so they will not be described here.

[0048] In this application, the conveying roller set 22 and the air knife 31 are arranged in the conveying channel 211, which can reduce the interference of the outside on the conveying roller set 22 and the air knife 31, so that the conveying roller set 22 can stably convey the battery sheet, and the airflow blown by the air knife 31 can also fully contact the battery sheet in the conveying channel 211, with good cooling effect.

[0049] In some embodiments, the conveying body 21 comprises a first side plate 212, a second side plate 213 and a top plate 214, the first side plate 212 and the second side plate 213 are oppositely arranged, the top plate 214 is connected between the first side plate 212 and the second side plate 213, and the top plate 214 and the first side plate 212 and the second side plate 213 define the conveying channel 211, and the air knife 31 is installed on the top plate 214.

[0050] Specifically, the first side plate 212 and the second side plate 213 are arranged at intervals, the top plate 214 is connected between the first side plate 212 and the second side plate 213, and the air knife 31 is installed on the top plate 214 to blow air downward to the battery sheet.

[0051] In the embodiment, the conveying roller set 22 is located below the battery piece, and the battery piece is conveyed by the conveying roller set 22, and the air knife 31 is located above the battery piece and blows air to the battery piece. In this design, the air blowing of the air knife 31 is not interfered by the conveying roller set 22, and the air flow formed by the air blowing of the air knife 31 directly contacts the battery piece, thereby having a better cooling effect.

[0052] Of course, the installation mode of the air knife 31 is not limited to the above, and in other embodiments, the air knife 31 can also be installed below the conveying roller set 22 and blows air from bottom to top.

[0053] In some embodiments, the top plate 214 is reversibly installed on the first side plate 212 or the second side plate 213.

[0054] For example, the top plate 214 is reversibly installed on the first side plate 212, and when the top plate 214 covers the opening between the first side plate 212 and the second side plate 213, the end of the top plate 214 away from the first side plate 212 overlaps the top surface of the second side plate 213. Of course, in other embodiments, the top plate 214 can also be reversibly installed on the second side plate 213, and when the top plate 214 covers the opening between the first side plate 212 and the second side plate 213, the end of the top plate 214 away from the second side plate 213 overlaps the top surface of the first side plate 212.

[0055] When an abnormal situation occurs, such as a piece blockage, the top plate 214 is flipped to open the opening between the first side plate 212 and the second side plate 213, so that the operator can conveniently handle the abnormal situation, greatly improving the convenience and work efficiency of operation, and providing a strong guarantee for stable and efficient operation of production.

[0056] In some embodiments, the top plate 214 is hingedly connected to the first side plate 212 or the second side plate 213. For example, the top plate 214 is reversibly connected to the first side plate 212 through a hinge. The hinge is used to reversibly install the top plate 214, which is simple and reliable, and facilitates the reduction of manufacturing cost of the conveying device 20.

[0057] In some embodiments, the surface of the top plate 214 away from the conveying channel 211 is also provided with a handle 23 for flipping the top plate 214. When an abnormal situation occurs, the handle 23 is used to conveniently flip the top plate 214 for subsequent handling of the abnormal situation.

[0058] For example, one end of the top plate 214 is reversibly connected to the first side plate 212, and the handle 23 is arranged at the end of the top plate 214 away from the first side plate 212.

[0059] In some embodiments, the top plate 214 comprises a plate frame 214a having a hollow region and a transparent plate 214b mounted on the plate frame 214a and covering the central region of the plate frame 214a, and the air knives 31 are mounted on the transparent plate 214b and / or the plate frame 214a. By providing the transparent plate 214b, the conveying of the battery sheet in the conveying channel 211 can be observed through the transparent plate 214b, so that the conveying of the battery sheet can be found in time and handled when the conveying of the battery sheet is abnormal.

[0060] For example, the transparent plate 214b is an acrylic plate. The acrylic plate has the characteristics of high temperature resistance and corrosion resistance, can reduce the influence of high temperature and water vapor in the air, and has a long service life.

[0061] In some embodiments, the air knives 31 are arranged in the width direction Y of the conveying channel 211. In this way, all the air knives 31 can uniformly blow air to the battery sheet passing through the conveying channel 211 in the width direction Y of the conveying channel 211, and the battery sheet can be uniformly cooled, and the cooling effect is good, and the air force on each part of the battery sheet is balanced, and the battery sheet is not easy to be blown apart due to uneven force.

[0062] The above battery sheet manufacturing production line 1, the air outlet 311 of the air knife 31 is arranged along the direction in which the battery sheet is conveyed by the conveying roller set 22, so that the air knife 31 can uniformly blow air to the battery sheet in the conveying direction of the battery sheet during the conveying of the battery sheet, thereby uniformly cooling the whole surface of the battery sheet, and the cooling effect is good. In addition, during the blowing process, the air force on each part of the battery sheet in the conveying direction of the battery sheet is balanced, and the battery sheet is not easy to be blown apart due to uneven force, thereby improving the production efficiency, and the risk of jamming and fragmentation is reduced, and the safety is high.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
