[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.

[0043] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] See also Figures 1 to 7 As shown, a cell drying device includes a drying assembly 1, which has multiple groups of drying assemblies 1, and all groups of drying assemblies 1 are arranged at intervals from each other along a first direction, and each group of drying assemblies 1 includes multiple drainage tubes 11 arranged in sequence along a second direction, and each drainage tube 11 is provided with multiple drainage holes 11a distributed at intervals along a third direction, and the drainage holes 11a are connected to the lumen of the drainage tube 11, and a transmission channel 5 is formed between two adjacent groups of drying assemblies 1, through which the cell 9 can pass. The transmission channel 5 is a long and narrow channel, and when the cell 9 penetrates into the transmission channel 5, the thickness direction of the cell 9 extends along the first direction.

[0045] The first direction, the second direction and the third direction are perpendicular to each other, and when the battery cell 9 passes through the transmission channel 5, at least one side of the surface of the battery cell 9 faces the drainage hole 11a. When the surface of the battery cell 9 is dried, the battery cell 9 enters the transmission channel 5, and the drying gas is injected into the lumen of the drainage tube 11. The drying gas acts on the surface of the battery cell 9 through the plurality of drainage holes 11a, thereby blowing off or evaporating the liquid on the battery cell 9, thereby achieving the purpose of drying the surface of the battery cell 9.

[0046] As a preferred method, Figures 1 to 7 As shown, the second direction extends in the horizontal direction and the third direction extends in the vertical direction, that is, the length extension direction of the drainage tube 11 is the vertical direction, all the drainage tubes 11 in the same group of drying components 1 are arranged at intervals in the horizontal direction, and the above-mentioned second direction is perpendicular to the first direction in the horizontal direction.

[0047] In other embodiments, the second direction may extend in the vertical direction and the third direction may extend in the horizontal direction, that is, the drainage tube 11 is set to extend in the horizontal direction, and all the drainage tubes 11 in the same group of drying components 1 are arranged at intervals in the vertical direction, and a transmission channel 5 for the battery cell 9 to penetrate can also be formed between two adjacent groups of drying components 1.

[0048] The battery cell 9 may enter the transmission channel 5 for drying treatment by moving in the vertical direction and exit from the transmission channel 5 after drying treatment, or may enter the transmission channel 5 for drying treatment by moving in the horizontal direction and exit from the transmission channel 5 after drying treatment.

[0049] As a preferred embodiment, the length extension direction of the transmission channel 5 extends in the horizontal direction and is perpendicular to the above-mentioned first direction. The transmission channel 5 has an inlet (not shown in the figure) for the battery cell 9 to pass in, and an outlet (not shown in the figure) for the battery cell 9 to pass out. The inlet and outlet are arranged at different ends of the length direction of the transmission channel 5. The battery cell 9 can move in the horizontal direction and enter the transmission channel 5 from the inlet, and then be passed out of the transmission channel 5 from the outlet.

[0050] In this embodiment, the upper portion of the transmission channel 5 is open, so that a plurality of battery cells 9 can move horizontally from above the drying device and pass into the transmission channel 5. When the battery cells 9 enter the transmission channel 5, the two side surfaces of the battery cells 9 face the drainage tubes 11 on both sides, so that the gas can flow to the surface of the battery cells 9.

[0051] As shown in the drawings, the drying component 1 further includes a support frame 12, and the drainage tube 11 is fixedly arranged on the support frame 12. Preferably, the drainage tube 11 is rotatably arranged on the support frame 12 around its own axis to fix the position of the drainage tube 11. Multiple drainage tubes 11 belonging to the same drying component 1 are arranged on one support frame 12. In order to facilitate the installation of all drying components 1, the drying device further includes a base, and all drying components 1 are installed on the base through the support frame 12 to fix the position of the drying component 1.

[0052] In this embodiment, an indicating assembly 7 for indicating the angular position of the drainage tube 11 is further provided between the support frame 12 and the drainage tube 11. When the indicating assembly 7 indicates the angular position of the drainage tube 11, the position of the drainage hole 11a on the drainage tube 11 is indicated accordingly. Specifically, the indicating assembly 7 includes a pointer 71, which is fixedly provided on the drainage tube 11 and can rotate synchronously with the rotation of the drainage tube 11, so that the tip position of the pointer 71 can change and always remain consistent with the position of the drainage hole 11a in the circumferential direction of the drainage tube 11.

[0053] Furthermore, the indicator assembly 7 also includes an indicator scale line, which is arranged on the support frame 12, and the pointer 71 is located above the indicator scale line. When the drainage tube 11 drives the pointer 71 to rotate, the rotation angle of the drainage tube 11 can be obtained by observing the indicator scale line. In practical applications, the rotation angle of the drainage tube 11 can be pre-adjusted. If the drainage tube 11 is at a specific angle, the contact area between the transported gas and the battery cell 9 is the largest, or the drying effect is the best, then the position of the indicator scale line pointed by the pointer 71 can be recorded, and before the drying device is used, part or all of the drainage tubes 11 are adjusted to the specific angle.

[0054] In some embodiments, the multiple drainage holes 11a extending along the same length direction on the drainage tube 11 are called drainage hole groups. Two groups of drainage hole groups are provided on the same drainage tube 11. The two groups of drainage hole groups are distributed 180° apart along the circumferential direction so as to be able to dry different surfaces of the battery cells 9 in two adjacent transmission channels 5. Since the relative positions of the two groups of drainage hole groups are fixed, the indicating component 7 can simultaneously indicate the positions of the two groups of drainage hole groups. Referring to the drawings, the drying device also includes a guide component 2, which is disposed on the base and is used to provide guidance for the battery cell 9 when passing through the transmission channel 5 along the length extension direction of the transmission channel 5. During the specific guidance, the guide component 2 cooperates with the battery cell 9 or a carrier that carries the battery cell 9.

[0055] The guide assembly 2 includes at least two guide wheels 21 arranged at intervals along the first direction, the axis lines of the plurality of guide wheels 21 are parallel to each other and perpendicular to the length extension direction of the transmission channel 5, or in other words, perpendicular to the transmission direction of the battery cell 9 when passing through the transmission channel 5, and a guide gap is formed between two adjacent guide wheels 21 along the first direction, and the guide gap is located in the transmission channel 5, that is, the width of the guide gap is not greater than the width of the transmission channel 5, and part of the outer peripheral edge of the guide wheel 21 is located on the inner side of the transmission channel 5. When the battery cell 9 is in the transmission channel 5, the two side surfaces of the battery cell 9 can maintain a certain distance from the drainage tube 11 along the first direction, which can avoid damage to the surface of the battery cell 9 on the one hand, and on the other hand, can also enable the gas ejected through the drainage hole 11a to act better on the surface of the battery cell 9, thereby improving the drying effect.

[0056] As shown in the drawings, in order to avoid the guide wheel 21 from directly contacting the surface of the battery cell 9 and damaging the battery cell 9, and to block the surface of the battery cell 9 and affect the drying effect, the guide assembly 2 also includes a guide rod 22, which extends along the first direction, and a plurality of guide wheels 21 are arranged at intervals along the length extension direction of the guide rod 22, and a guide gap is formed between two adjacent guide wheels 21, and the number and position of the guide gap are consistent with the number and position of the transmission channel 5. By installing the guide wheel 21 on the guide rod 22, the height of the guide wheel 21 can be adjusted so that the guide wheel 21 can accurately contact the carrier. In practical applications, in each group of guide assemblies 2, the number of guide wheels 21 is the same as the number of groups of drying assemblies 1, so that a guide gap is formed between any two adjacent guide wheels 21, so that each battery cell 9 or carrier moving through the transmission channel 5 can contact the guide wheel 21, thereby achieving its guidance.

[0057] In this embodiment, as shown in the accompanying drawings, the guide assembly 2 is arranged at the lower part of the transmission channel 5. When the battery cell 9 or the carrier moves horizontally along the second direction from above the drying device as a whole, the lower part of the carrier moves in the guide gap during the process of being transmitted from one side of the transmission channel 5 to the other side, and cooperates with the two guide wheels 21 to avoid deviation in the moving direction.

[0058] In some other embodiments, the guide assembly 2 may also be disposed at the upper portion of the transmission channel 5, for example, the cell carrier 8 is configured to move horizontally from the bottom of the drying device to transport the cell 9; in some other embodiments, the guide assembly 2 may also be disposed at both the upper and lower portions of the transmission channel 5 to achieve good guidance of the cell carrier mechanism 81.

[0059] As shown in the drawings, in this embodiment, the transmission channel 5 extends in the horizontal direction and the drainage tubes 11 extend in the vertical direction. In the direction of the length extension of the transmission channel 5, every two drainage tubes 11 form a group, and there is a certain distance between two adjacent groups of drainage tubes 11 to form a mounting portion. A plurality of mounting portions connected along the first direction together form an mounting space, and the mounting space can be used for the installation of one of the guide components 2. Specifically, all the drainage tubes 11 in all the drying components 1 are arranged in a square array, that is, the number of drainage tubes in multiple groups of drying components is equal, and the positions of the drainage tubes 11 in multiple groups of drying components along the first direction correspond. All the drainage tubes 11 in the same group of drying components 1 are called drainage tube rows, and all the drainage tubes 11 at the same position along the first direction are called drainage tube columns 10. There is one or more guide components 2 between any two adjacent drainage tube columns 10. More preferably, guide components 2 are provided on both sides of the drainage tube 11 along the length extension direction of the transmission channel 5, so that the transmission operation can be more stable when the battery cell 9 passes through the two drainage tubes 11 of two adjacent groups of drying components 1.

[0060] Among them, the two drainage tubes 11 in a group are set in opposite directions, and the drainage tubes of two adjacent drying components along the first direction are positioned relative or oppositely. The two sides of a transmission channel 5 are two adjacent drying components. When the battery cell 9 passes through the transmission channel 5, the two opposite drainage tubes 11 will transport gas to its surface.

[0061] The drying device further comprises a gas supply device for outputting drying gas, so as to supply drying gas into the draft tube 11 of each drying component 1 .

[0062] In some embodiments, Figures 5 to 7 As shown, each drainage tube 11 is connected to the gas supply device via an air supply pipe 6. By means of valves arranged on each air supply pipe 6, the flow rate and flow velocity of the gas entering into the lumen of each drainage tube 11 can be accurately controlled as needed.

[0063] In other embodiments, Figures 1 to 4 As shown, the drying device also includes a flow equalizing component 4 having an air storage cavity, and the flow equalizing component 4 is connected to the air supply device and the plurality of drainage tubes 11. The drying gas first enters the air storage cavity of the flow equalizing component 4, and then is transmitted to the plurality of drainage tubes 11 respectively, so that the type, flow rate, flow rate, etc. of the gas entering the plurality of drainage tubes 11 are consistent. Specifically, see Figure 4 As shown, the flow equalizing component 4 includes multiple flow equalizing tubes 41, which extend along a first direction. All the flow equalizing tubes 41 are spaced apart along the length extension direction of the transmission channel 5 and are installed on a base. One flow equalizing tube 41 is connected to all the drainage tubes 11 in the same drainage tube column 10, or all the drainage tubes 11 in the same drainage tube row, or all the drainage tubes 11 in the drying component 1. Here, each equalizing flow tube 41 is provided with a plurality of outlets 43 facing upward and at least one inlet 42 facing downward at intervals along the length direction. The inlet 42 is connected to the gas supply device to receive the drying gas. The lower parts of the plurality of drainage tubes 11 are inserted into the plurality of outlets 43 one by one. In order to enable the gas in the equalizing flow tube 41 to enter the plurality of drainage tubes 11 as simultaneously and equally as possible, when one inlet 42 is provided, the inlet 42 is provided in the middle of the equalizing flow tube 41. When more than one inlet 42 is provided, the plurality of inlets 42 are evenly distributed on the equalizing flow tube 41. In the working state, when the gas supply device transports gas to the equalizing flow tube 41, the gas enters the equalizing flow tube 41 from the inlet 42, and first diffuses along the length direction of the equalizing flow tube 41. Since the end of the equalizing flow tube 41 is in a closed state, the gas will rise evenly and enter the plurality of drainage tubes 11 at the same time.

[0064] All the flow equalizing tubes 41 can be interconnected so that the dry gas received by the battery cell 9 during the horizontal movement along the transmission channel 5 is consistent; in some embodiments, each flow equalizing tube 41 can also be connected to the gas supply device through a gas supply pipe, so that the battery cell 9 can receive dry gases of different types and / or flow rates and / or flow rates during the horizontal movement along the transmission channel 5.

[0065] The gas supply device can deliver high-temperature gas or normal-temperature gas to the flow equalizing tube 41. In order to avoid moisture in the gas flowing onto the battery cell 9, which causes the surface of the battery cell 9 to become wet, only high-temperature gas and normal-temperature gas are selected to dry the battery cell 9. Specifically, when delivering high-temperature gas, the high-temperature gas flows to the surface of the battery cell 9 through the drainage holes 11a, so that after the high-temperature gas contacts the surface of the battery cell 9, the liquid remaining on the surface of the battery cell 9 evaporates, thereby drying the battery cell 9; when delivering normal-temperature gas, the normal-temperature gas flows to the battery cell 9 through the drainage holes 11a to blow off the liquid remaining on the battery cell 9. By delivering gases of different temperatures, different drying effects can be produced on the battery cell 9. That is to say, in practical applications, the delivery method of the gas supply device can be selected according to different drying effects. Specifically, after the processing of the battery cell 9 is completed, a certain amount of liquid will remain on its surface. At this time, if the gas supply device transports 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 transporting normal temperature gas to it, the droplets can be blown away to facilitate their falling. Therefore, two drying devices can be set at the same time. The two drying devices are parallel and the transmission channels 5 correspond to each other, so that the battery cell 9 can move through the two drying devices in sequence. The two drying devices arranged in sequence transport normal temperature gas and high temperature gas respectively. In this way, after the processing of the battery cell 9 is completed, the droplets remaining on its surface can be blown away by normal temperature gas, so that the small liquid beads 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. In addition, due to the high price of electroplating liquid, a device for recovering liquid can also be set below the drying component. At this time, the base can only not be set with a bottom, and only retain the side wall, and the drying device can be installed in the electroplating equipment or other equipment through the side wall.

[0066] In the working state, the battery cell 9 first enters the transmission channel 5 that moves through the first drying device, and the normal temperature gas blown out from the drainage holes 11a of the drainage tube 11 will blow off the liquid droplets remaining on the surface of the battery cell 9, or blow away the liquid droplets. The battery cell 9 then moves through the transmission channel 5 of the second drying device, and the high temperature gas blown out from the drainage holes 11a of the drainage tube 11 is blown out from the drainage holes 11a of the drainage tube 11, so that a relatively high temperature environment is formed in the drying device, and the liquid on the surface of the battery cell 9 that moves into the environment can evaporate quickly.

[0067] 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 drainage pipe 11; after the gas passes through the dryer to remove the moisture therein, it can effectively prevent the surface of the battery cell 9 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 9, 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 9. Since the purpose of conveying normal temperature gas is to reduce droplets, it is necessary to convey gas of different strengths to the battery cells 9 at different moving positions. For example, the gas volume at the inlet and outlet of the transmission channel 5 can be reduced to prevent the droplets from being blown too far and unable to be recovered. That is to say, when the gas supply device is transporting gas at room temperature, the drainage pipes 11 are connected to the gas supply device through their own gas supply pipes. An exhaust valve and a pressure regulating valve can be set on each gas supply pipe, so that the flow rate and flow velocity of the gas flowing through the drainage pipe 11 can be accurately regulated.

[0068] When the gas supply device is conveying high-temperature gas, the gas supply device includes a fan, a heater, a filter, and a diverter. After the high-temperature gas is simultaneously output by the drainage pipe 11, the heat released by the high-temperature gas will be superimposed on each other, resulting in a temperature-increasing environment in the drying device. Therefore, when the gas supply device is conveying high-temperature gas, there is no need to regulate the gas flow rate and flow rate output by each drainage pipe 11. All the drainage pipes 11 in the same drainage pipe column 10 or drainage pipe row or drying component 1 can be uniformly supplied with gas. In addition, since the high-temperature gas needs to be heated by a heater, its cost is relatively high. A device for recovering the high-temperature gas can be added above the drying device so that the high-temperature gas can be recycled. At this time, the gas supply device also includes a gas storage tank. Although not shown in the figure, the utility model also provides an electroplating device, which includes a drying device as described above, and a cell carrier 8. Through the cooperation between the cell carrier 8 and the drying device, the cell 9 can be dried online without removing the cell 9 from the cell carrier 8. After the drying, the cell 9 can be directly transferred to the next process, which greatly improves the processing efficiency and reduces the risk of cell fragmentation.

[0069] Specifically, the cell carrier 8 includes a cell carrier for carrying a single cell, and the cell carrier has a plurality of cells arranged at intervals along a first direction, and the spacing between two adjacent cell carriers is consistent with the spacing between two adjacent transmission channels; the electroplating equipment also includes a driving device, which is connected to the cell carrier and drives the cell carrier to move along a second direction, and in a working state, the cell carrier passes through the transmission channel. When the cell carrier passes through the transmission channel, the drainage tube 11 transports the gas to the surface of the cell 9 through the drainage hole 11a.

[0070] The electroplating equipment also includes an electroplating tank, and the electroplating tank and the drying device are both located on the moving path of the cell carrier, and the electroplating tank and the drying device, or the electroplating tank, the drying device and the electroplating tank are sequentially arranged on the moving path. When the electroplating tank and the drying device are sequentially arranged on the moving path, the drying device is used to dry the cell 9 that has been electroplated. When the electroplating tank, the drying device and the electroplating tank are sequentially arranged on the moving path, the drying device is used to dry the cell 9 that has been electroplated only once in multiple electroplatings, so as to avoid mixing of the chemical solutions in different electroplating tanks.

[0071] The electroplating equipment also includes a recovery device, which is arranged below the drying device and communicated with the adjacent electroplating tank to collect the liquid dripping from the drying device and transport it to the electroplating tank.
