[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0055] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0056] In some embodiments, see Figures 1 to 3The present application discloses a cell processing device 100, including a cell curing device 10, through which a carrier 13 carrying cells (not shown) is heated in sequence, so that the copper paste on the cell is processed to form a metal electrode of the cell.

[0057] In some embodiments, the carrier 13 is a part of the cell curing device 10 , or is a part of an external device.

[0058] In some embodiments, see Figures 1 to 3 The cell curing device 10 includes: a vacuum chamber 11, a conveying mechanism 12, a heating mechanism 14 and a cooling mechanism 15. The vacuum chamber 11 extends in the front-to-back direction, and a heating area 111 and a cooling area 112 are arranged in the vacuum chamber 11 from front to back. The conveying mechanism 12 is placed in the vacuum chamber 11, the heating mechanism 14 is arranged in the heating area 111, and the cooling mechanism 15 is arranged in the cooling area 112. The carrier 13 carrying the cell is conveyed from front to back through the heating area 111 and the cooling area 112 by the conveying mechanism 12, so that the heating mechanism 14 heats and cures the copper paste on the cell in a vacuum environment, so as to reduce the risk of the high-temperature copper paste being oxidized by contact with the air, and then the cooling mechanism 15 cools the cured copper paste, thereby achieving the effect of reducing the risk of the copper paste being oxidized in the air.

[0059] In other embodiments, the vacuum chamber 11 may extend in a straight line along other directions such as the left-right direction, or extend in a zigzag manner along other directions. The conveying mechanism 12 conveys the carrier 13 along the extending direction of the vacuum chamber 11 .

[0060] In some embodiments, see Figure 2 and Figure 3 The vacuum chamber 11 includes a plurality of hollow shells 110 connected end to end.

[0061] In some embodiments, before the cell curing device 10 is used for curing, the copper paste is attached to the cell by means of screen printing, painting, etc.

[0062] In some embodiments, there are multiple carriers 13 , and the carriers 13 are sequentially transported through the vacuum chamber 11 by the transport mechanism 12 , so that the heating mechanism 14 can sequentially heat and solidify the copper paste of the battery cells on different carriers 13 .

[0063] In some embodiments, see Figure 4The carrier 13 includes a carrier plate 131 and a flower basket 132. The carrier plate 131 is used to contact the conveying mechanism 12. The bottom of the flower basket 132 is connected to the top surface of the carrier plate 131. The flower basket 132 carries the battery cells, so that the carrier plate 131 drives the flower basket 132 and the battery cells on the flower basket 132 to transfer. The flower basket 132 is provided with a hollow structure 1321 around it. The setting of the hollow structure 1321 helps to improve the heat convection on the flower basket 132 and the battery cells, so that the heating mechanism 14 can fully heat the copper paste on the battery cells, and the cooling mechanism 15 can cool the copper paste on the battery cells, so as to achieve the purpose of improving the curing efficiency of the copper paste of the battery cells.

[0064] In some embodiments, see Figure 4 There are multiple flower baskets 132 on each carrier 13 , and the multiple flower baskets 132 are distributed in sequence along the front-to-back direction on the carrier 131 , so that one carrier 13 can carry more battery cells.

[0065] In some embodiments, when the inner diameter of the vacuum chamber 11 and the lengths of the heating area 111 and the cooling area 112 in the front-to-back direction are both specified as a first value, the size of the carrier 131 is specified as a second value according to the inner diameter of the vacuum chamber 11 and the lengths of the heating area 111 and the cooling area 112 in the front-to-back direction, and a plurality of flower baskets 132 are distributed in an array on the carrier 131. In the left-right direction, the flower baskets 132 on the carrier 131 are in two, three or more rows, thereby satisfying the effect of the carrier 131 of the second value size carrying more flower baskets 132.

[0066] In some embodiments, see Figure 4 The carrier 13 also includes an escape space 133, which is located between two adjacent columns of flower baskets 132. When the carrier 13 passes through the heating area 111 or the cooling area 112, a portion of the heating mechanism 14 or a portion of the cooling mechanism 15 extends into the escape space 133, so that the heating mechanism 14 or the cooling mechanism 15 can approach the battery cell inside the carrier 13, thereby satisfying the effect of the heating mechanism 14 and the cooling mechanism 15 to fully heat or cool the copper paste of the battery cell on the carrier 13.

[0067] In some embodiments, the avoidance space 133 extends in the front-to-back direction to reduce the risk of interference between the flower basket 132 and the heating mechanism 14 or the cooling mechanism 15 .

[0068] In some embodiments, see Figure 2 and Figure 3The conveying mechanism 12 is a conveying wheel 121 arranged in a front-to-back manner and disposed on the left and right sides of the vacuum chamber 11 respectively and relatively. The circumferential surface of the conveying wheel 121 contacts the bottom surface of the carrier 131. When an external force drives the conveying wheel 121 to rotate, the conveying wheel 121 can convey the carrier 131.

[0069] In some embodiments, the transfer wheel 121 is driven by a magnetic fluid or directly driven by a motor.

[0070] In some embodiments, grooves 1311 are respectively provided on the left and right sides of the carrier 131, and the transmission wheel 121 is located in the groove 1311 and contacts the top wall of the groove 1311, so that the transmission wheel 121 is limited by the groove 1311, which helps to reduce the risk of the carrier 131 falling off the transmission mechanism 12, thereby achieving the purpose of improving the stability of the transmission mechanism 12 in transmitting the carrier 13.

[0071] In other embodiments, the conveying mechanism 12 includes a conveying belt extending in the front-to-back direction or a plurality of conveying rollers arranged in the front-to-back direction, and the conveying belt and the conveying rollers are respectively used to contact the bottom surface of the carrier plate 131 .

[0072] In some embodiments, see Figure 2 The heating mechanism 14 includes a first heating assembly 141 disposed in the vacuum chamber 11, and the first heating assembly 141 includes a plurality of first heating elements 1411 disposed around the inner wall of the vacuum chamber 11. When the conveying mechanism 12 conveys the carrier 13 through the heating area 111 and through the first heating assembly 141, part of the conveying mechanism 12 is surrounded by the first heating assembly 141, and the plurality of first heating elements 1411 surround the outer side of the carrier 13, thereby helping to improve the uniformity of heating by the heating mechanism 14.

[0073] In some embodiments, the first heating element 1411 is a heating plate or a heating wire.

[0074] In some embodiments, the number of the first heating elements 1411 is four, and the four first heating elements 1411 are distributed on the left and right sides and the upper and lower sides of the vacuum chamber 11 .

[0075] In some embodiments, see Figure 2The heating mechanism 14 also includes a second heating component 142 disposed between the two inner walls of the vacuum chamber 11. The second heating component 142 extends from top to bottom in the vacuum chamber 11 and is located between the two first heating members 1411 on the left and right sides. When the conveying mechanism 12 conveys the carrier 13 through the heating area 111 and allows the carrier 13 to pass through the first heating component 141, the second heating component 142 is placed in the avoidance space 133 along the up and down direction to heat the interior of the carrier 13, thereby helping to improve the uniformity of heating performed by the heating mechanism 14.

[0076] In some embodiments, see Figure 2 In the up-down direction, there is a first gap (not marked) between the second heating assembly 142 and the first heating element 1411 located on one side of the vacuum chamber 11 , so that the carrier plate 131 can pass between the second heating assembly 142 and the first heating element 1411 .

[0077] In other embodiments, the number of the first heating elements 1411 is five or more, and at least one first heating element 1411 is disposed on each of the upper, lower, left, and right sides of the vacuum chamber 11 .

[0078] In some embodiments, the second heating element 142 is at least one heating plate or heating wire.

[0079] In some embodiments, there are multiple heating mechanisms 14 , and one heating mechanism 14 heats a battery cell on a carrier 13 . Multiple heating mechanisms 14 heat multiple carriers 13 at the same time, which helps to improve the heating and curing efficiency of the copper paste.

[0080] In some embodiments, see Figure 3 The cooling mechanism 15 includes a first cooling assembly 151 disposed around the vacuum chamber 11, and the first cooling assembly 151 includes a plurality of first cooling members 1511. When the conveying mechanism 12 conveys the carrier 13 through the cooling area 112 and through the first cooling assembly 151, a portion of the conveying mechanism 12 is surrounded by the first cooling assembly 151, and the first cooling assembly 151 surrounds the outer side of the carrier 13, thereby helping to improve the uniformity of cooling performed by the cooling mechanism 15.

[0081] In some embodiments, the first cooling member 1511 is a cooling pipeline having a first cooling medium flowing therethrough.

[0082] In other embodiments, the first cooling member 1511 is a plate-shaped component, and a cooling channel for the first cooling medium to flow through is provided on the first cooling member 1511 .

[0083] In some embodiments, the number of the first cooling members 1511 is four, and the four first cooling members 1511 are distributed on the left and right sides and the upper and lower sides of the vacuum chamber 11 .

[0084] In some embodiments, see Figure 3 The cooling mechanism 15 also includes a second cooling component 152 disposed between the two inner walls of the vacuum chamber 11. The second cooling component 152 extends from top to bottom in the vacuum chamber 11. The second cooling component 152 is between the two first cooling components 1511 on the left and right sides. When the conveying mechanism 12 conveys the carrier 13 through the cooling area 112 and passes through the first cooling component 151, a portion of the second cooling component 152 is placed in the avoidance space 133 to cool the interior of the carrier 13, thereby helping to improve the uniformity of cooling performed by the cooling mechanism 15.

[0085] In some embodiments, see Figure 3 In the up-down direction, there is a second gap (not marked) between the second cooling component 152 and the first cooling member 1511 located on the downward side of the vacuum chamber 11 , so that the carrier plate 131 can pass between the second cooling component 152 and the first cooling member 1511 .

[0086] In some embodiments, the second cooling assembly 152 includes at least one second cooling member (not labeled).

[0087] In some embodiments, the construction of the second cooling member is the same as the construction of the first cooling member 1511.

[0088] In other embodiments, the number of the first cooling members 1511 is five or more, and at least one first cooling member 1511 is disposed on each of the upper, lower, left, and right sides of the vacuum chamber 11 .

[0089] In some embodiments, a second cooling medium (not shown) is further provided in the cooling area 112. When the conveying mechanism 12 conveys the carrier 13 through the cooling area 112, the cooling mechanism 15 cools the battery cell while contacting the solidified copper paste on the battery cell through the second cooling medium, thereby cooling the copper paste, and wrapping the solidified copper paste with the second cooling medium, thereby reducing the risk of the copper paste coming into contact with the air.

[0090] In some embodiments, the second cooling medium is nitrogen flowing in the cooling area 112. The nitrogen flows through the hollow structure 1321 on the flower basket 132, so that the nitrogen contacts the battery cells and the solidified copper paste on the battery cells, so as to achieve the effect of fully and quickly cooling the battery cells and the solidified copper paste on the battery cells. At the same time, the copper paste is wrapped by the chemically stable nitrogen as a protective gas, thereby achieving the effect of reducing the risk of contact between the copper paste and the air.

[0091] In other embodiments, the second cooling medium is a gas medium such as argon.

[0092] In some embodiments, sealing mechanisms 1121 are provided in front and behind the cooling region 112 , and the cooling region 112 is formed into a closed space through the sealing mechanisms 1121 , which helps to reduce the risk of diffusion or leakage of the second cooling medium toward the heating region 111 .

[0093] In some embodiments, when the copper slurry is sufficiently cooled, the sealing mechanism 1121 behind the cooling area 112 is gradually opened to gradually connect the cooling area 112 with the outside, thereby reducing the risk of impact of the vacuum chamber 11 due to the internal and external pressure difference.

[0094] In some embodiments, the cell curing device 10 is provided with a vacuum generating device (not shown) for evacuating the cooling area 112. After the carrier 13 is transferred out of the cooling area 112, the sealing mechanism 1121 behind the cooling area 112 is closed to form a closed space in the cooling area 112, and the vacuum generating device evacuates the cooling area 112, thereby reducing the air in the vacuum chamber 11.

[0095] In some embodiments, the vacuum chamber 11 is provided with a first through hole (not shown) and a second through hole (not shown), the first through hole and the second through hole are respectively located at the front end and the rear end of the cooling region 112, the first through hole is connected to the vacuum generating device, and the second through hole is connected to the external second cooling medium source, when the second cooling medium flows from the second through hole to the first through hole in the front-to-back direction, the second cooling medium contacts the copper paste on the battery cell, thereby achieving the effect of cooling the copper paste on the battery cell. Preferably, the first through hole and the second through hole are located on opposite sides of the vacuum chamber 11, so that the second cooling medium can flow evenly through the cooling region 112.

[0096] For further information, see Figure 5 The first through hole (not shown) and the second through hole (not shown) are relatively arranged on the left and right sides of the vacuum chamber 11. The cooling mechanism 15 further includes an air-uniform structure 153, which is arranged on the side of the vacuum chamber 11 where the second through hole is arranged. When the second cooling medium flows from the second through hole to the first through hole, the second cooling medium is dispersed by the air-uniform structure 153, thereby facilitating the second cooling medium to flow uniformly through the cooling region 112 in the front-rear direction.

[0097] In some embodiments, the gas uniforming structure 153 is connected to the first cooling member 1511 .

[0098] In other embodiments, the air uniforming structure 153 and the first cooling member 1511 are spaced apart from each other.

[0099] In some embodiments, the gas uniforming structure 153 is a gas uniforming plate, and third through holes (not shown) for the second cooling medium to pass through are uniformly formed on the gas uniforming plate.

[0100] In some embodiments, the number of the first through hole and the number of the second through hole are both plural.

[0101] In some embodiments, the gas-uniform structure 153 is located on the side of the first cooling member 1511 close to or away from the second through hole, so that the second cooling medium passes through the gas-uniform structure 153 and the first cooling member 1511, and the second cooling medium is evenly dispersed and cooled, thereby helping to improve the cooling effect of the second cooling medium. The first cooling member 1511 is provided with a channel (not shown) for the second cooling medium to pass through.

[0102] When the first cooling member 1511 is a cooling pipeline, the channel is the gap between adjacent cooling pipelines. When the first cooling member 1511 is a plate-like structure, the channel is a plurality of through-hole structures provided on the first cooling member 1511. In some embodiments, the cooling mechanism 15 does not include the second cooling assembly 152.

[0103] In other embodiments, the second cooling component 152 of the cooling mechanism 15 is consistent with the first cooling component 1511, and both are provided with a channel for the second cooling medium to pass through.

[0104] In other embodiments, the second cooling medium is a liquid medium such as hydrofluoroether, mineral oil, silicone oil, etc. that is not easily volatile and not easy to react with copper slurry. An immersion cooling tank (not shown) is provided in the cooling area 112, and the conveying mechanism 12 passes through the immersion cooling tank to drive the carrier 13 to be immersed in the second cooling medium, so that the second cooling medium is in full contact with the battery cell and the solidified copper slurry on the battery cell, thereby achieving sufficient cooling of the copper slurry and reducing the risk of contact between the copper slurry and the air.

[0105] In some embodiments, see Figure 1 The vacuum chamber 11 further includes a buffer region 113, which is located in front of the heating region 111. Sealed structures 1131 are provided in front and rear of the buffer region 113. Before the photovoltaic material begins to enter the vacuum chamber 11, the sealed structure 1131 in the rear of the buffer region 113 is closed, and the sealed structure 1131 in front of the buffer region 113 is opened, so that the carrier 13 is conveyed into the buffer region 113.

[0106] When the carrier 13 completely enters the buffer area 113, the sealed structure 1131 in front of the buffer area 113 is closed, and the sealed structure 1131 behind the buffer area 113 is opened, so that the carrier 13 is transferred to the heating area 111. By sequentially opening and closing the sealed structures 1131 in front and behind the buffer area 113, when the carrier 13 enters the vacuum chamber 11, only the buffer area 113 in the vacuum chamber 11 is connected to the outside, that is, as long as the vacuum degree of the buffer area 113 is destroyed, it is helpful to reduce the change in the vacuum degree in the vacuum chamber 11, thereby achieving energy saving effect.

[0107] In some embodiments, the battery cell curing device 10 is provided with a vacuum generating device (not shown) for evacuating the buffer area 113. When the two sealed structures 1131 are closed to form a closed space in the buffer area 113, the vacuum generating device evacuates the buffer area 113, thereby reducing the air in the vacuum cavity 11.

[0108] In some embodiments, the sealing mechanism 1121 of the cooling area 112 and the sealing structure 1131 of the buffer area 113 are both sealing valves, sealing plates, sealing covers or sealing doors.

[0109] In some embodiments, see Figure 1 The battery cell processing equipment 100 also includes a loading mechanism 16 and a unloading mechanism 17. The loading mechanism 16 is arranged in front of the vacuum chamber 11 and is used to load the carrier 13 toward the conveying mechanism 12, so that the conveying mechanism 12 conveys the carrier 13 through the vacuum chamber 11. After the copper paste on the battery cell is cured, the unloading mechanism 17 arranged at the rear of the vacuum chamber 11 unloads the carrier 13 from the conveying mechanism 12, thereby achieving the effect of the battery cell curing device 10 automatically curing the copper paste on the battery cell, thereby improving the production efficiency of the battery cell.

[0110] In some embodiments, the loading mechanism 16 and the unloading mechanism 17 are both manipulators or robots.

[0111] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
