Description

Technical Field

[0001] The utility model relates to the field of solar cell manufacturing, in particular to a cell cell drying carrier and surface treatment equipment. Background Art

[0002] During the manufacturing process of solar cells, some processes require multiple drying treatments on the surface of the cell. For example, in the electroplating process, when the cell is electroplated, chemicals with different components are loaded into different electroplating tanks. To avoid the influence of each other, the cell needs to be dried every time it completes electroplating in a plating tank to remove the liquid on its surface and prevent the cell from carrying liquid into the next electroplating tank.

[0003] In the prior art, when drying battery cells, the battery cells need to be placed individually in a battery cell drying device for drying. However, the battery cells are usually carried by a carrier during processing. Therefore, after the battery cells are processed, they need to be removed from the carrier and placed in a drying device for drying, and then placed back on the carrier for processing, and this cycle repeats, resulting in low processing efficiency and increasing the risk of battery cell damage.

[0056] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0057] See also Figures 1 to 13 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0058] In order to facilitate the description and understanding of the specific structure of the cell drying carrier 100 and the cell surface treatment equipment, an XYZ three-dimensional coordinate system is constructed in the embodiment of the utility model, wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, the first direction X and the second direction Y extend in the horizontal direction respectively, and the third direction Z extends in the vertical direction.

[0059] Embodiment 1

[0060] like Figure 1 As shown, the present embodiment provides a cell drying carrier 100, which includes: a carrier 10, a bearing seat 20 and a first drying assembly 30; the bearing seat 20 is configured to carry a single vertically placed cell, and a plurality of bearing seats 20 are provided, which are spaced apart at the lower end of the carrier 10 along the first direction X, that is, the plurality of carried cell sheets are spaced apart along the first direction X; the first drying assembly 30 is configured to dry the cell, and a plurality of first drying assemblies 30 are provided, and all groups of first drying assemblies 30 are spaced apart at the lower end of the carrier 10 along the first direction X, and the first drying assemblies 30 and the bearing seat 20 are alternately spaced apart in sequence, and each group of first drying assemblies 30 includes a plurality of drying components 31 sequentially arranged along the second direction Y, and the drying components 31 are configured to provide drying gas along the third direction through a working end, and the working end of the drying component 31 is at least higher than the lower edge of the cell.

[0061] The battery cell drying carrier 100 in this embodiment can directly dry the battery cells carried on the carrier 20 online through the first drying component 30, that is, the battery cell drying carrier 100 can directly dry the battery cells when it is stationary or moving, and there is no need to disassemble the battery cells for additional drying treatment, which reduces the risk of battery cell fragments. After the drying treatment, the battery cells can be directly transferred to the next process on the carrier, which greatly improves the processing efficiency.

[0062] When the battery cell needs to be dried, the battery cell can be carried by the support seat 20 in a stationary state or in a moving state, and the drying gas provided by the working end of the drying component 31 along the third direction Z acts on the surface of the battery cell, so that the liquid on the battery cell is blown off quickly, or directly blown off, or evaporated, thereby achieving the purpose of drying the surface of the battery cell. In a preferred example, the working end of the drying component 31 is slightly lower than the upper edge of the battery cell and much higher than the lower edge of the battery cell, so that the drying gas provided by the working end of the drying component 31 acts on the surface of the battery cell with the largest area. Because the drying component 31 provides the drying gas along the third direction through the working end, under this structure, after the gas flows out through the working end, it gradually flows from the upper edge of the battery cell to the lower edge of the battery cell, that is, the surface of the battery cell is within the flow range of the gas, thereby achieving the drying of the entire surface of the battery cell and accelerating the blowing off or drying of the liquid on the surface of the battery cell.

[0063] To speed up the blowing off or drying of the liquid on the surface of the battery, Figures 2 to 5 As shown, in a specific implementable example, the drying component 31 includes: a first drainage tube 311 and a second drainage tube 312, the tube openings of the first drainage tube 311 and the second drainage tube 312 provide drying gas along a third direction Z; a plurality of drainage holes 50 are arranged on the circumference of the first drainage tube 311 and are distributed at intervals along the third direction Z, the drainage holes 50 are connected to the tube cavity of the first drainage tube 311, and at least some of the drainage holes 50 are facing the supporting seat 20. The cross-sectional aperture of the first drainage tube 311 is larger than the cross-sectional aperture of the tube opening of the second drainage tube 312, the length of the first drainage tube 311 in the third direction Z is larger than the length of the second drainage tube 312, and the tube opening position of the second drainage tube 312 in the third direction Z is higher than the position of some of the drainage holes 50 on the first drainage tube 311.

[0064] It should be noted that a plurality of drainage holes 50 can be arranged at random intervals on the circumference of the first drainage tube 311. Since a drying component 31 needs to dry two opposite surfaces of two adjacent battery cells, preferably, the plurality of drainage holes 50 on the first drainage tube 311 are directly opposite to the opposite surfaces of two adjacent battery cells, that is, the drainage holes 50 arranged along the third direction Z on the first drainage tube 311 can be divided into two groups, one group of drainage holes 50 faces one surface of the previous battery cell, and the other group of drainage holes 50 faces the opposite surface of the next battery cell. The drying gas provided by the working ends, that is, the nozzles, of the first drainage tube 311 and the second drainage tube 312 can act on the battery cells. Preferably, the nozzle position of the second drainage tube 312 is higher than the position of the drainage holes 50 on the first drainage tube 311, that is, the second drainage tube 312 does not cover the drainage holes 50 on the first drainage tube 311. In the working state, the gas in the first drainage tube 311 flows out through the drainage hole 50 and / or the tube mouth of its working end, and the gas in the second drainage tube 312 flows out through the tube mouth of its working end. That is to say, the gas in the first drainage tube 311 can flow to the relative surface of the battery cell adjacent to the first drainage tube 311 through the drainage hole 50, and can also flow to the relative surface of the adjacent battery cell through the tube mouth of the working end of the first drainage tube 311. The gas in the second drainage tube 312 flows to the relative surface of the adjacent battery cell through the tube mouth of the working end of the first drainage tube 311.

[0065] Furthermore, if Figures 2 to 3 As shown, the first drainage tube 311 and the second drainage tube 312 are alternately arranged along the second direction; or, as shown Figures 4 to 5 As shown, the second drainage pipe 312 is disposed around the first drainage pipe 311. The pipe openings of the first drainage pipe 311 and the second drainage pipe 312 both provide drying gas, and multiple channels provide drying gas to accelerate the drying process of the battery cell.

[0066] In one example, the flow rate and flow velocity of the drying gas provided by the first drainage tube 311 are the same as or different from the flow rate and flow velocity of the drying gas provided by the second drainage tube 312; in a preferred example, the flow rate and flow velocity of the drying gas provided by the first drainage tube 311 are greater than the flow rate and flow velocity of the drying gas provided by the second drainage tube 312. At this time, the drainage holes 50 on the first drainage tube 311 can also provide drying gas to the periphery of the first drainage tube 311. The liquid on the upper end of the battery cell can drip downward by itself under the action of gravity. Under the action of gravity, increasing the drying gas with a small flow rate and a small flow rate can accelerate the dripping of the liquid on the upper end of the battery cell surface for drying. The liquid on the lower end of the battery cell surface includes not only the liquid remaining before the drying process, but also the liquid dripping from the upper end of the battery cell surface. The amount of liquid is large. The stepped working ends of the first drainage tube 311 and the second drainage tube 312 can simultaneously meet the drying process of the liquid at different positions on the upper and lower ends of the battery cell surface. The liquid on the upper end of the battery cell surface is mainly dried by the drying gas provided by the second drainage tube 312. The liquid on the lower end of the battery cell surface passes through the first drainage tube 311, the circumferential drainage holes 50 of the first drainage tube 311, and the drying gas provided by the second drainage tube 312 to dry the battery cell together. The effective area and force of the drying gas at the lower end of the battery cell surface are increased, further accelerating the drying process of the battery cell.

[0067] The specific drying gas includes any one of inert gases such as nitrogen or air, as long as it can dry the surface of the battery cell and does not react with the surface of the battery cell. It can be selected according to actual conditions and is not limited here.

[0068] In this embodiment, the first drying component 30 is added to the conventional cell carrier. The conventional cell carrier is configured to transport the cells. The cell drying carrier 100 in this embodiment is configured to directly dry the cells placed on the carrier. Whether to add the first drying component 30 can also be considered according to the different functions of the carrier. To facilitate the use of the carrier, the first drying component 30 can be detachably set on the conventional cell carrier. When the first drying component 30 needs to be set, multiple groups of the first drying components 30 are directly installed at the lower end of the carrier 10; when the first drying component 30 is not needed, multiple groups of the first drying components 30 are directly removed from the carrier 10.

[0069] In a specific example that can be implemented, multiple groups of first drying components 30 can be installed on the lower end of the carrier 10 by screws respectively. This installation method requires the carrier to be disassembled from the device, and the carrier is turned over to install and disassemble the first drying component 30. In order to solve the problem of cumbersome installation and disassembly process, in a preferred example that can be implemented, the first drying component 30 also includes a first plug-in 32, and multiple drying components 31 are arranged on the first plug-in 32 in sequence along the second direction Y, and the cross section of the first plug-in 32 is an inverted trapezoid; the lower end of the carrier 10 is provided with a first socket 11, the first socket 11 extends along the second direction Y, and the track cross section of the first socket 11 is an inverted trapezoid; the inverted trapezoidal cross section of the track of the first socket 11 matches the inverted trapezoidal cross section of the first plug-in 32, at least the upper bottom side of the inverted trapezoid of the first plug-in 32 is larger than the lower bottom side of the inverted trapezoid of the first socket 11, and the sizes of the first socket 11 and the first plug-in 32 match, so that the first plug-in 32 can be inserted into the first socket 11 along the second direction Y. In this manner, the operator only needs to stand beside the equipment to install or remove the first socket 11 on the carrier 10 through the first slide groove on the first drying component 30, which is convenient for operation.

[0070] In one example, the carrier 10 located above the first socket 11 is provided with through holes at intervals, and other components of the first drying component 30, such as a gas supply device for outputting drying gas to the drying component 31, are arranged above the carrier 10, and the gas pipe of the gas supply device can pass through the through hole to communicate with the working end of the drying component 31. This way of installing other components of the first drying component 30 occupies a large space, and the gas pipes are arranged in a disorderly manner, which is easy to cause inconvenience to the process before the battery cell is dried. Figure 6 As shown, in a preferred example, there is a gap between the top surface of the first plug-in 32 and the bottom surface of the first socket 11, and other components of the first drying assembly 30 can be arranged in the gap, which will not affect the drying function of the battery cell drying carrier 100 itself, nor will it affect the process before the battery cell is dried. For example, one end of the air pipe is connected to the air supply device, and the other end passes through the first socket 11 to enter the gap, penetrates the first plug-in 32 and is connected to the working end of the drying component 31, or one end of the air pipe is connected to the air supply device, and the other end passes through the first socket 11 to be connected to the gap, the non-working end of the drying component 31 is installed on the first plug-in 32, and a cavity connected to the gap is opened in the first plug-in 32.

[0071] In a specific example that can be implemented, the first drying assembly 30 further includes a gas supply device for outputting drying gas, so as to supply drying gas to each drying component 31 .

[0072] In one example, each drying component 31 is connected to the gas supply device through an air pipe, and the flow rate and flow velocity of the gas entering each drying component 31 can be accurately controlled as needed by the valves arranged on each air pipe. When the flow rate and flow velocity of the drying gas provided to the first drainage pipe 311 and the second drainage pipe 312 are required to be the same, the first drainage pipe 311 and the second drainage pipe 312 can be connected in sequence through the same air pipe, and the same valve can be arranged. For example, a cavity whose bottom is connected to the first drainage pipe 311 and the second drainage pipe 312 at the same time is arranged on the first plug-in 32, and the top of the cavity is connected to an air pipe, or the air pipe is connected to the interval, the cavity is connected to the interval, or an air pipe is arranged in the interval along the second direction, and the first drainage pipe 311 and the second drainage pipe 312 directly penetrate the first plug-in 32 and are connected to the same air pipe, and the ends of the air pipes penetrate the first socket 11 or an extension pipe is arranged to be connected to the first socket 11. The first drainage tube 311 and the second drainage tube 312 are connected to the gas supply device; when the flow rate and flow velocity requirements of the drying gas provided to the first drainage tube 311 and the second drainage tube 312 are different, the first drainage tube 311 and the second drainage tube 312 can be connected respectively through different air pipes, and different valves can be set. For example, a cavity whose bottom is connected to the first drainage tube 311 and the second drainage tube 312 respectively is set on the first plug-in 32, and the top of the cavity is connected to the two air pipes, or two air pipes are set in the interval along the second direction, the first drainage tube 311 and the second drainage tube 312 directly penetrate the first plug-in 32 and are respectively connected to the two air pipes, and the ends of the air pipes penetrate the first socket 11 or are separately provided with extension pipes to be connected to the gas supply device.

[0073] In another example, the first drying component 30 also includes a first flow equalizing component having an air storage cavity, the first flow equalizing component is connected to the air supply device and multiple drying components 31, the drying gas first enters the air storage cavity of the first flow equalizing component, and then is transmitted to the multiple drying components 31 respectively, so that the type, flow rate, flow rate, etc. of the gas entering each of the multiple drying components 31 are consistent. Specifically, the first flow equalizing component includes multiple first flow equalizing tubes, the first flow equalizing tubes are arranged along the second direction Y, the number of drying components 31 of multiple groups of first drying components 30 is equal and corresponds along the first direction X, one first flow equalizing tube is connected to at least one drying component 31 in each group of first drying components 30, and the first flow equalizing tube is connected to the air supply device through an air pipe. Among them, the first flow equalizing tube is arranged in the first plug-in 32, that is, forming the cavity in the above example.

[0074] Here, each first flow equalizing tube is provided with a plurality of outlets 433 facing downwards and at least one inlet 432 facing upwards at intervals along the length direction, i.e., the second direction Y. The inlet 432 is connected to the gas supply device to receive the drying gas, and the upper parts of the plurality of drying components 31 are inserted into the plurality of outlets 433 one by one. In order to enable the gas in the first flow equalizing tube to enter the plurality of drying components 31 as simultaneously and equally as possible, when one inlet 432 is provided, the inlet 432 is provided in the middle of the first flow equalizing tube. When more than one inlet 432 is provided, the plurality of inlets 432 are evenly distributed on the first flow equalizing tube. In the working state, when the gas supply device transports gas to the first flow equalizing tube, the gas enters the first flow equalizing tube from the inlet 432, and first diffuses along the length direction of the first flow equalizing tube. Since the end of the first flow equalizing tube is in a closed state, the gas will descend evenly and enter the plurality of drying components 31 at the same time.

[0075] When the flow rate and flow velocity of the drying gas that needs to enter the first drainage tube 311 are the same as the flow rate and flow velocity of the drying gas that enters the second drainage tube 312, the first drainage tube 311 and the second drainage tube 312 on the same drying component 31 share the same first flow equalizing tube; when the flow rate and flow velocity of the drying gas that needs to enter the first drainage tube 311 are different from the flow rate and flow velocity of the drying gas that enters the second drainage tube 312, the first drainage tube 311 and the second drainage tube 312 on the same drying component 31 use two different first flow equalizing tubes at the same time, and the two first flow equalizing tubes are connected to the first drainage tube 311 and the second drainage tube 312 through air pipes, respectively. In other words, the two first flow equalizing tubes are both arranged in the first plug-in 32, and the first drainage tube 311 and the second drainage tube 312 are connected to the first flow equalizing tube by plugging, or are connected to the first flow equalizing tube by pipeline transportation.

[0076] The gas supply device can deliver high-temperature gas or normal-temperature gas to the first equalizing flow tube. In order to avoid moisture in the gas flowing to the battery cell, which causes the surface of the battery cell to become wet, only high-temperature gas and normal-temperature gas are selected to dry the battery cell. Specifically, when delivering high-temperature gas, the high-temperature gas flows to the surface of the battery cell through the drainage hole 50, so that after the high-temperature gas contacts the surface of the battery cell, the liquid remaining on the surface of the battery cell evaporates, thereby drying the battery cell; when delivering normal-temperature gas, the normal-temperature gas flows to the battery cell through the drainage hole 50 to blow off the liquid remaining on the battery cell. By delivering gases of different temperatures, different drying effects can be produced on the battery cell. That is to say, in actual applications, the delivery method of the gas supply device can be selected according to different drying effects.

[0077] Specifically, after the battery cell is processed, a certain amount of liquid will remain on its surface. At this time, if the gas supply device delivers high-temperature gas, it is difficult to ensure that all the liquid can evaporate. At the same time, due to the surface tension of the liquid and the molecular force between the solid and the liquid, the droplets may not fall. By delivering normal-temperature gas to it, the droplets can be blown away to facilitate their falling. Therefore, two drying components 31 can be arranged in sequence along the first direction X at the same time, and the two drying components 31 deliver normal-temperature gas and high-temperature gas respectively, that is, there are two drying components 31 between two battery cells, or one drying component 31 delivers normal-temperature gas and high-temperature gas in sequence. In this way, after the battery cell is processed, the droplets remaining on its surface can be blown away by normal-temperature gas, so that the small liquid droplets or other forms of liquid remaining on its surface can evaporate quickly when passing through the high-temperature gas, thereby completing the drying of the battery cell.

[0078] When the above-mentioned gas supply device is conveying normal temperature gas, the gas supply device includes a fan, a dryer, a gas tank, an exhaust valve, a pressure regulating valve and a filter. After the fan generates gas, the gas will pass through the dryer, the gas tank, the exhaust valve, the pressure regulating valve and the filter in sequence and flow into the drying component 31; after the gas passes through the dryer to remove moisture therein, it can effectively prevent the surface of the battery cell from becoming more moist after being blown by the normal temperature gas. The dried gas will be stored in the gas tank to avoid insufficient supply of normal temperature gas. When drying the battery cell, the exhaust valve is opened to allow the gas in the gas tank to flow out, and after flowing through the pressure regulating valve, it is filtered in the filter to prevent impurities from being conveyed to the battery cell. Since the purpose of conveying normal temperature gas is to reduce droplets, it is necessary to convey gas of different intensities to battery cells at different moving positions. When the gas supply device conveys normal temperature gas, the first drainage pipe 311 adopts a method of connecting the gas supply device through a respective gas pipe. An exhaust valve and a pressure regulating valve can be set on each gas pipe, so as to accurately regulate the flow rate and flow velocity of the gas flowing through the first drainage pipe 311.

[0079] When the air supply device is conveying high-temperature gas, the air supply device includes a fan, a heater, a filter, and a diverter. After the high-temperature gas is simultaneously output by the first drainage pipe 311, the heat released by the high-temperature gas will be superimposed on each other, resulting in a temperature-increasing environment formed in the drying device. Therefore, when the air supply device is conveying high-temperature gas, there is no need to regulate the gas flow rate and flow rate output by each first drainage pipe 311, and all first drainage pipes 311 can be uniformly supplied with gas.

[0080] In order to enable the cell drying carrier 100 to dry the cell online, in a specific example, the cell drying carrier 100 further includes a driving device, which drives the cell to move in the horizontal direction and the vertical direction.

[0081] Embodiment 2

[0082] This embodiment also provides a surface treatment device, which includes: the cell drying carrier 100 and the second drying component 40 described in any one of the above-mentioned embodiments; Figures 7 to 9As shown, the second drying components 40 are provided with multiple groups, and all groups of second drying components 40 are arranged at intervals from each other along the first direction X. Each group of second drying components 40 includes multiple third drainage tubes 41 arranged in sequence along the second direction Y. The third drainage tubes 41 are provided with multiple drainage holes 50 distributed at intervals along the third direction Z. The drainage holes 50 are connected to the tube cavity of the third drainage tubes 41. A transmission channel 44 for the battery cells to pass through is formed between two adjacent groups of second drying components 40. At least part of the drainage holes 50 face the transmission channel 44. The spacing between two adjacent transmission channels 44 is consistent with the spacing between two adjacent bearing seats 20. The transmission channel 44 is a long and narrow channel. When the battery cells are inserted into the transmission channel 44, the thickness direction of the battery cells extends along the first direction X. In the working state, the gas flows out through the drainage holes 50 of the third drainage tube 41 and / or the nozzles at the working end thereof, that is, the gas in the third drainage tube 41 can flow to the relative surface of the battery cell adjacent to the third drainage tube 41 through the drainage holes 50, and can also flow to the relative surface of the adjacent battery cell through the nozzles at the working end of the third drainage tube 41. In addition to the above-mentioned battery cell drying carrier 100, the surface treatment equipment of this embodiment is additionally provided with an independent second drying component 40. The first drying component 30 is installed on the carrier for drying when the carrier is stationary and moving. The second drying component 40 is installed in the surface treatment equipment for drying the battery cell moved therein, further improving the drying efficiency of the battery cell, thereby completing the surface treatment of the battery cell. The battery cell surface treatment equipment includes two states when working. The first working state is that the single battery cell carried by the support seat 20 is inserted into or leaves the transmission channel 44 along the third direction Z, that is, the battery cell moves in the vertical direction to enter the transmission channel 44 for drying treatment and moves out of the transmission channel 44 along the vertical direction after drying treatment; the second working state is that the single battery cell carried by the support seat 20 passes through the transmission channel 44 along the second direction Y, that is, the battery cell moves in the horizontal direction to enter the transmission channel 44 for drying treatment and moves out of the transmission channel 44 along the horizontal direction after drying treatment; in addition, it also includes a third working state, which is a combination of the first working state and the second working state, the single battery cell carried by the support seat 20 is first inserted into the transmission channel 44 along the third direction Z, and then the battery cell passes through part of the transmission channel 44 along the second direction Y, and finally the battery cell leaves the transmission channel 44 along the third direction Z, that is, the battery cell moves into the transmission channel 44 along the vertical direction, passes through part of the transmission channel 44 along the horizontal direction, and finally moves out of the transmission channel 44 along the vertical direction. The working end of the drying component 31 and the tube opening of the third drainage tube 41 are arranged at corresponding intervals, so as to avoid mutual influence between the drying component 31 and the third drainage tube 41 .When the battery cell is located in the transmission channel 44, the third drainage pipe 41 is located below the drying component 31, and the drying component 31 can also continuously transport gas, which is equivalent to the first drying component 30 and the second drying component 40 drying the battery cell at the same time.

[0083] When the battery cells need to pass directly through the transmission channel 44, the transmission channel 44 has an entrance (not shown in the figure) for the battery cells to enter, and an exit (not shown in the figure) for the battery cells to exit. The entrance and exit are arranged at different ends of the length direction of the transmission channel 44. The battery cells can move in the horizontal direction and enter the transmission channel 44 from the entrance, and then be transmitted out of the transmission channel 44 from the exit.

[0084] In this example, the upper part of the transmission channel 44 is openly arranged, and when the battery cell only needs to be inserted into the transmission channel 44, the battery cell can be directly inserted from the top of the transmission channel 44 along the third direction Z, so that a plurality of battery cells can be horizontally moved from the top of the drying device and penetrate into the transmission channel 44. When the battery cell enters the transmission channel 44, the two side surfaces of the battery cell face the third drainage tubes 41 on both sides, so that the gas can flow to the surface of the battery cell.

[0085] The first drying component 30 first performs the first drying process on the upper surface of the battery cell, and the second drying component 40 performs the second drying process on the entire surface of the battery cell. The two drying processes can speed up the drying process time of the battery cell surface, thereby quickly achieving the purpose of drying the entire surface of the battery cell, thereby improving the drying efficiency and drying effect of the battery cell.

[0086] In order to achieve two drying treatments on the surface of the battery cell, such as Figure 1 and Figure 7 As shown, in a specific example that can be implemented, a second plug-in 12 is provided at both ends of the carrier 10 along the first direction X, and the second drying component 40 also includes a mounting seat 42, and the mounting seat 42 is configured to carry a plurality of third drainage tubes 41. A second socket 421 is provided on the mounting seat 42, and the second socket 421 extends along the second direction Y. In the first working state, the second plug-in 12 is inserted into the second socket 421; in the second working state, the second plug-in 12 and the second socket 421 are slidably connected along the second direction Y; in the third working state, the second plug-in 12 is first inserted into the second socket 421, the second plug-in 12 is slidable in the second socket 421, and finally the second plug-in 12 leaves the second socket 421.

[0087] In a specific example, the second drying assembly 40 further includes a combined gas supply and exhaust device for conveying drying gas and absorption gas, so as to supply drying gas to each third drainage pipe 41 or absorb gas through each third drainage pipe 41 .

[0088] In one example, each third drainage tube 41 is individually connected to the gas supply and exhaust combination device through an air pipe. By means of valves arranged on each air pipe, the flow rate and flow velocity of the gas entering each third drainage tube 41 or the flow rate and flow velocity of the gas extracted into each third drainage tube 41 can be precisely controlled as needed.

[0089] like Fig.10 As shown, in another example, the second drying component 40 also includes a second flow equalizing tube 431 component having an air storage cavity. The second flow equalizing tube 431 component is connected to the air supply and exhaust device and multiple third drainage tubes 41. When it is necessary to provide drying gas through the third drainage tubes 41, the drying gas first enters the air storage cavity of the second flow equalizing component 43, and then is transmitted to the multiple third drainage tubes 41 respectively, so that the type, flow rate, flow rate, etc. of the gas entering each of the multiple third drainage tubes 41 are consistent; when it is necessary to exhaust gas through the third drainage tube 41, the gas first enters the cavity of the third drainage tube 41 through the drainage hole 50 on the third drainage tube 41, and then is transmitted to the air storage cavity of the second drainage component. Specifically, the second flow equalizing component 43 includes multiple second flow equalizing tubes 431, which are arranged along the second direction Y. The number of third drainage tubes 41 of multiple groups of second drying components 40 is equal and corresponds to each other along the first direction X. One second flow equalizing tube 431 is connected to at least one third drainage tube 41 in each group of second drying components 40, and the second flow equalizing tube 431 is connected to the air supply and exhaust device through an air pipe.

[0090] Here, each second flow balancing tube 431 is provided with a plurality of inlets and outlets facing upwards and at least one inlet and outlet facing downwards at intervals along the length direction, i.e., the second direction Y. The inlet and outlet facing downwards are connected to the gas supply and extraction device to receive the drying gas or the extracted gas, and the lower portions of the plurality of third flow guide tubes 41 are inserted into the plurality of inlets and outlets facing upwards in a one-to-one correspondence. When there is one inlet and outlet facing downwards, the inlet and outlet is provided in the middle of the second flow balancing tube 431, and when there is more than one inlet and outlet facing downwards, the plurality of inlets and outlets facing downwards are evenly distributed on the second flow balancing tube 431. In the working state, when the gas supply and exhaust device transports gas to the second flow equalizing tube 431, the gas enters the second flow equalizing tube 431 from the downward inlet and outlet, and first diffuses along the length direction of the second flow equalizing tube 431. Since the end of the second flow equalizing tube 431 is in a closed state, the gas will rise evenly and enter multiple third drainage tubes 41 at the same time; when the gas supply and exhaust device extracts gas through the third drainage tubes 41, the gas enters the second flow equalizing tube 431 from the upward inlet and outlet, and first diffuses along the length direction of the second flow equalizing tube 431. Since the end of the second flow equalizing tube 431 is in a closed state, the gas will descend evenly and enter the gas supply and exhaust device through the downward inlet and outlet.

[0091] When the gas supply and exhaust assembly delivers gas, it delivers high-temperature gas or normal-temperature gas; when delivering high-temperature gas, the high-temperature gas flows to the battery cell through the drainage holes 50 of the third drainage tube 41 to dry the battery cell; when delivering normal-temperature gas, the normal-temperature gas flows to the battery cell through the drainage holes 50 of the third drainage tube 41 to blow off the liquid on the battery cell. When the gas supply and exhaust assembly extracts gas, the liquid on the surface of the battery cell follows the surrounding gas and leaves the surface of the battery cell through the drainage holes 50 of the third drainage tube 41 to dry the liquid on the battery cell; further, the tube mouth of the third drainage tube 41 is uncovered and flows upward along the third direction Z, and gas can also be supplied and exhausted through the gas supply and exhaust assembly. The cross-sectional aperture of the working end of the drying component 31 is smaller than the cross-sectional aperture of the tube mouth of the third drainage tube 41. The third drainage tube 41 cooperates with the drying gas provided downward by the absorbing drying component 31. The gas flows in the same direction, which can take away the attached liquid on the battery cell and accelerate the drying speed.

[0092] The internal structure of the gas supply device in the gas supply and exhaust assembly in this example is the same as the internal structure of the gas supply device on the cell drying carrier 100, and will not be repeated here. It should be noted here that when the first drying component 30 and the second drying component 40 simultaneously transport high-temperature gas, since the high-temperature gas needs to be heated by a heater, its cost is relatively high. A device for recovering high-temperature gas can be added above the cell surface treatment equipment so that the high-temperature gas can be recycled. When the gas supply and exhaust assembly extracts gas, the exhaust device in the gas supply and exhaust assembly includes a vacuum pump, a gas storage tank, a dryer, an exhaust valve, a pressure regulating valve and a filter. After the vacuum pump is started, the gas will pass through the filter, the pressure regulating valve, the exhaust valve, the dryer and enter the gas storage tank in sequence. When the gas passes through the filter, the impurities in the liquid on the surface of the cell are directly removed. The gas passes through the dryer to remove the liquid following the gas, effectively absorbs the liquid on the surface of the cell and dries it, and releases the absorbed liquid to other places at the outlet of the dryer. The flow rate and flow rate of the absorbed gas can be accurately regulated by the exhaust valve and the pressure regulating valve.

[0093] like Figures 11 to 13 As shown, in a specific example that can be implemented, the second drying component 40 further includes a support frame 45, and the third drainage tube 41 is fixedly arranged on the support frame 45. Preferably, the third drainage tube 41 is rotatably arranged on the support frame 45 around its own axis to fix the position of the third drainage tube 41. Multiple third drainage tubes 41 belonging to the same second drying component 40 are arranged on one support frame 45. In order to facilitate the installation of all second drying components 40, the second drying device further includes a base, and all second drying components 40 are installed on the base through the support frame 45 to fix the position of the second drying components.

[0094] like Figure 11 to Figure 12As shown, in a specific example that can be implemented, an indicating assembly 46 for indicating the angular position of the drainage tube is further provided between the support frame 45 and the third drainage tube 41. When the indicating assembly 46 indicates the angular position of the third drainage tube 41, the position of the drainage hole 50 on the third drainage tube 41 is indicated accordingly. Specifically, the indicating assembly 46 includes a pointer 461, which is fixedly provided on the third drainage tube 41 and can rotate synchronously with the rotation of the third drainage tube 41, so that the tip position of the pointer 461 can change and always remain consistent with the position of the drainage hole 50 in the circumferential direction of the third drainage tube 41.

[0095] Furthermore, the indicator assembly 46 also includes an indicator scale line, which is arranged on the support frame 45, and the pointer 461 is located above the indicator scale line. When the third drainage tube 41 drives the pointer 461 to rotate, the rotation angle of the third drainage tube 41 can be obtained by observing the indicator scale line. In practical applications, the rotation angle of the drainage tube can be adjusted in advance. When the third drainage tube 41 is at a specific angle, the contact area between the transported or extracted gas and the battery cell is the largest, or the drying effect is the best, then the position of the indicator scale line pointed by the pointer 461 can be recorded, and before the drying device is used, part or all of the third drainage tubes 41 are adjusted to the specific angle.

[0096] In one example, the plurality of drainage holes 50 extending along the same length direction on the third drainage tube 41 is referred to as a drainage hole 50 group. Two drainage holes 50 groups are provided on the same third drainage tube 41. The two drainage holes 50 groups are distributed 180° apart along the circumferential direction, so that the relative surfaces of two adjacent battery cells can be dried simultaneously. Since the relative positions of the two drainage holes 50 groups are fixed, the indicating assembly 46 can simultaneously indicate the positions of the two drainage holes 50 groups.

[0097] As shown in the accompanying drawings, in a specific example that can be implemented, the second drying device also includes a guide component 47, which is arranged on the base and is used to provide guidance for the battery cell when it passes through the transmission channel 44 along the second direction Y. During the specific guidance, the guide component 47 cooperates with the battery cell or the supporting seat 20 that supports a single battery cell.

[0098] Specifically, the guide assembly 47 includes at least two guide wheels 471 arranged at intervals along the first direction X, the axis lines of the plurality of guide wheels 471 are parallel to each other and perpendicular to the length extension direction of the transmission channel 44, and a guide gap is formed between two adjacent guide wheels 471 along the first direction X, and the guide gap is located in the transmission channel 44, that is, the width of the guide gap is not greater than the width of the transmission channel 44, and part of the outer peripheral edge of the guide wheel 471 is located on the inner side of the transmission channel 44. When the battery cell is in the transmission channel 44, both sides of the battery cell can maintain a certain distance from the third drainage tube 41 along the first direction X, which can avoid damage to the surface of the battery cell on the one hand, and on the other hand, can also enable the gas ejected through the drainage hole 50 to act better on the surface of the battery cell, thereby improving the drying efficiency.

[0099] In order to avoid the guide wheel 471 from directly contacting the surface of the battery cell and damaging the battery cell, and to avoid the surface of the battery cell being blocked and affecting the drying effect, as shown in the drawings, in a specific example that can be implemented, the second drying assembly 40 also includes a guide rod 272, which extends along the first direction X, and a plurality of guide wheels 471 are arranged at intervals along the length extension direction of the guide rod 272, and a guide gap is formed between two adjacent guide wheels 471, and the number and position of the guide gaps are consistent with the number and position of the transmission channels 44. By installing the guide wheel 471 on the guide rod 272, the height of the guide wheel 471 can be adjusted so that the guide wheel 471 can accurately contact the battery cell drying carrier 100. In actual applications, in each group of guide components 47, the number of guide wheels 471 is the same as the number of groups of the second drying components 40. In this way, a guide gap is formed between any two adjacent guide wheels 471, so that each battery cell moving through the transmission channel 44 or the supporting seat 20 carrying a single battery cell can contact the guide wheel 471, thereby achieving guidance thereof.

[0100] Specifically, in one example, the guide assembly 47 is disposed at the lower portion of the transmission channel 44. When the battery cell drying carrier 100 moves horizontally along the second direction Y from above the second drying assembly 40 as a whole, the lower portion of the battery cell drying carrier 100 moves in the guide gap during the process of being transmitted from one side of the transmission channel 44 to the other side, and cooperates with the two guide wheels 471 to avoid deviation in the moving direction. In another example, the guide assembly 47 may also be disposed at the upper portion of the transmission channel 44, for example, the battery cell drying carrier 100 is configured to move horizontally from below the second drying assembly 40 to transmit the battery cells. In some other examples, the guide assembly 47 may also be disposed at both the upper and lower portions of the transmission channel 44 to achieve good guidance of the battery cell drying carrier 100.

[0101] In a specific example that can be implemented, the battery cell surface treatment equipment also includes a recovery device, which is located below the second drying component 40 and is configured to collect liquid dripping from the battery cell and can recover the dripping liquid; the battery cell surface treatment equipment also includes a surface treatment tank, which is configured to store or contains liquid for surface treatment of a single battery cell carried on the carrier 20, specifically, the surface treatment tank is an electroplating tank; the surface treatment tanks and the recovery device are alternately arranged in sequence below the battery cell drying carrier 100, and the recovery device is interconnected with adjacent surface treatment tanks to transport the liquid recovered by the recovery device to the surface treatment tank.

[0102] Specifically, the cell drying carrier 100 carries the cell and is driven by the driving device to enter the surface treatment tank for surface treatment. After the surface treatment is completed, the cell leaves the liquid in the surface treatment tank. At this time, the cell drying component is located above the surface treatment tank. The first drying component 30 first performs the first drying on the surface of the cell to drip a large amount of residual liquid on the cell into the surface treatment tank. The driving device drives the cell drying carrier 100 to enter the second drying component 40 for a second drying to blow off or dry a small amount of liquid on the cell. At this time, the recovery device can collect and recycle the dripping liquid, and the cell surface treatment is completed.

[0103] In summary, the embodiment of the utility model provides a battery cell drying carrier 100 and a surface treatment device. The battery cell drying carrier 100 includes a carrier 10 and a bearing seat 20. The bearing seat 20 is configured to carry a single vertically placed battery cell. A plurality of bearing seats 20 are provided, which are arranged at intervals along the first direction X at the lower end of the carrier 10. The battery cell drying carrier 100 also includes: a first drying component 30, which is configured to dry the battery cells. The first drying components 30 are provided in multiple groups. All groups of first drying components 30 are arranged at intervals along the first direction X at the lower end of the carrier 10. The first drying components 30 and the bearing seat 20 are arranged alternately in sequence. Each group of first drying components 30 includes a plurality of drying components 31 arranged in sequence along the second direction Y. The drying components 31 are configured to provide drying gas along the third direction Z through a working end, and the working end of the drying component 31 is higher than the lower edge of the battery cell. The cell drying carrier 100 in the embodiment of the utility model can directly dry the cell online through the first drying component 30, and there is no need to disassemble the cell for additional drying treatment, which reduces the risk of cell fragmentation. After the drying treatment, the cell can be directly transferred to the next process on the carrier, which greatly improves the processing efficiency; the cell surface treatment equipment in the embodiment of the utility model can directly dry the cell after the cell surface treatment, and the drying efficiency and drying effect of the cell can be improved through the second drying component 40. Therefore, the cell drying carrier 100 and the surface treatment equipment in the embodiment of the utility model effectively overcome some shortcomings in the prior art and have high industrial utilization value.
