[0032] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship of a unit or feature relative to another unit or feature as shown in the accompanying drawings for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive words used in this article are interpreted accordingly.

[0033] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The background technology of this application points out that the existing drying equipment usually has a large heat loss. Specifically, after the previous process is completed, the battery cell is moved through the interior of the drying equipment by a transmission mechanism, and the high temperature inside the drying equipment is used to evaporate the moisture on its surface, thereby achieving the drying effect. However, under this structure, the drying equipment will provide a certain space for the transmission mechanism and the battery cell to pass through, causing the high-temperature gas inside the drying equipment to flow into the air through this space, resulting in a high heat loss inside the drying equipment. It is necessary to maintain a certain temperature inside the drying equipment by increasing the heating time or heating temperature, etc., which reduces the processing efficiency and increases the processing cost; in addition, this space will also cause external impurities to enter the drying equipment during gas exchange, resulting in a decrease in the cleanliness inside the drying equipment, which is easy to cause impurities to adhere to the surface of the battery cell, affecting the subsequent processing of the battery cell.

[0035] Based on this, the present application provides a cell drying device. The cell drying device divides the drying assembly into a drying box and a transfer box. The top of the transfer box is provided with an openable and closable transfer opening, so that the drying device can enhance its sealing performance by closing the transfer opening during the period when the cell is not baked. Since the transmission device is arranged in the drying assembly, the exposed space of the drying device can be further reduced, thereby reducing heat loss, improving processing efficiency, improving the internal cleanliness of the drying device, and reducing costs; in addition, a cover plate is arranged on the top of the transfer box, which is convenient for loading the cell from above the drying device, so that the drying device can be applied to most cell processing requirements.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0037] See attached Figure 1 -Attached Figure 4 As shown, the present application provides a battery cell drying device, which at least includes a drying component 10 and a transmission mechanism 20, wherein the drying component 10 is used to dry the battery cells, and the transmission mechanism 20 is used to transmit the battery cells. Specifically, the drying component 10 includes a drying box 101 and a transfer box 102, wherein the transfer box 102 is arranged at the end of the drying box 101 and is connected to the inside thereof, and a transfer opening 1023 that can be opened and closed is arranged on the top of the transfer box 102, and the transmission mechanism 20 is arranged in the drying box 101, and penetrates the drying box 101, and has a transmission path, and the battery cells are transmitted from the transmission start end to the transmission end end.

[0038] Among the various pre-processes that require drying of the battery cells, most of the processes are wet processes, that is, liquid is required during processing. In order to avoid liquid leakage, when transferring the battery cells, the battery cells need to be lifted to the top of the processing tank containing the liquid, and then moved to the periphery of the drying equipment for loading. In other words, the battery cells need to be loaded from above the drying equipment. Therefore, in this embodiment, the transfer opening 1023 of the transfer box 102 is set at the top to facilitate loading of the drying equipment.

[0039] See attached Figure 5As shown, when the battery cells are transported to the top of the transfer box 102, the transfer opening 1023 is in an open state, so that the transfer box 102 is connected to the inside and the outside through the transfer opening 1023, that is, the transfer box 102 is in an open state, and the battery cells will move into the transfer box 102 and be placed on the transmission mechanism 20; when a batch of battery cells is dried, or when the drying equipment is not needed temporarily, the transfer opening 1023 is closed. At this time, the transfer box 102 is isolated from the outside, which can avoid the rapid drop in temperature inside the drying equipment. When the next batch of battery cells is processed, no extra time is required to warm up the inside of the drying equipment, thereby reducing costs. In addition, by isolating the transfer box 102 from the outside, external impurities no longer enter the transfer box 102, thereby improving the cleanliness of the drying component 10.

[0040] In practical applications, the structure of the drying equipment can be any of the following:

[0041] (1) The transfer box 102 has one and is disposed at the end of the drying box 101. The transmission start end of the transmission mechanism 20 is located in the transfer box 102, and the transmission end extends in a direction away from the drying assembly 10; see the attached Figure 2 As shown, under this structure, when the transfer opening 1023 is closed, one end of the drying box 101 can be isolated from the outside, and the battery cells will be loaded through the transfer opening 1023. After drying, the battery cells will be transferred to the next process through the transmission mechanism 20.

[0042] (2) There are two transfer boxes 102, which are respectively arranged at the two ends of the drying box 101. The transmission start and end of the transmission mechanism 20 are respectively located in the two transfer boxes 102; see the attached Figure 1 As shown, under this structure, when the transfer opening 1023 is closed, both ends of the drying box 101 can be isolated from the outside, and the battery cells can be loaded and unloaded through the transfer opening 1023.

[0043] (3) The drying box 101 is located in the transfer box 102. There is a certain distance between one end of the transfer box 102 and the end of the drying box 101, and a loading portion 107 is formed. The starting end of the transmission is located in the loading portion 107. The transfer opening 1023 is located at the top of the loading portion 107. The drying box 101 and the end of the transfer box 102 away from the loading portion 107 are flush, and a discharge opening is opened. The transmission end of the transmission mechanism 20 extends through the discharge opening in a direction away from the drying component 10; see the attached Figure 3As shown, under this structure, by setting the drying box 101 in the transfer box 102, the poor airtightness caused by the loose connection between the drying box 101 and the transfer box 102 can be avoided. One end of the drying box 101 is isolated from the outside, and the battery cells will be loaded through the transfer opening 1023. After drying, the battery cells will be transferred to the next process through the transmission mechanism 20.

[0044] (4) The drying box 101 is located in the transfer box 102. Both ends of the transfer box 102 are at a certain distance from the ends of the drying box 101, and form a loading part 107 and a unloading part 108 respectively. The transfer start and end are respectively located in the loading part 107 and the unloading part 108. The two transfer openings 1023 are respectively located at the top of the loading part 107 and the unloading part 108; see the attached Figure 4 As shown, under this structure, the drying box 101 is arranged in the transfer box 102, and both ends are isolated from the outside. The battery cells will be loaded and unloaded through the transfer opening 1023, so that the airtightness of the drying equipment can be further improved.

[0045] In one possible implementation, see the attached Figure 6 As shown, a handling device 30 is arranged adjacent to the cell drying device, and the handling device 30 is located around the transfer box 102, and the handling height is greater than the height of the transfer box 102. When the transmission start end is located in the transfer box 102 and the loading part 107, the handling device 30 first transports the cell to the top of the transfer box 102, and then moves into the transfer box 102, and places the cell at the transmission start end of the transmission mechanism 20, so that the cell can move along the transmission path and be dried; if the transmission end is located in the transfer box 102 and the unloading part 108, then after the cell is dried, the handling device 30 transports the cell from the transmission end of the transmission mechanism 20 to a place away from the drying device for the next process. If the transmission end passes through the drying box 101 and extends in a direction away from the drying assembly 10, the cell will be directly transported to the next station by the transmission mechanism 20 after drying for the next process. The handling equipment 30 may be a device with a mobile transportation function, such as a forklift, a suspended conveying equipment, and an automatic guided vehicle, etc., and this application does not limit this.

[0046] Further, see Appendix Figure 7As shown, when the transfer box 102 is arranged at the end of the drying box 101, a shelf 103 is arranged in the transfer box 102 at the end of the transmission, and the shelf 103 is located on one side of the transmission mechanism 20, and the upper surface of the shelf 103 is located at the same horizontal plane as the upper surface of the transmission mechanism 20. The battery cells at the end of the transmission will be moved toward the shelf 103 under the drive of the transmission mechanism 20, and part of the area or the whole area is placed on the shelf 103. The shelf 103 is located below the transfer opening 1023 of the transfer box 102, and the handling equipment 30 can enter the transfer opening 1023 and take the battery cells out of the transfer box 102 to complete the unloading. Correspondingly, when the drying box 101 is arranged in the transfer box 102, the shelf 103 is arranged in the unloading part 108.

[0047] In one possible implementation, see the attached Figure 8 As shown, the two ends of the inner cavity of the drying box 101 are drying openings 1011, and the drying openings 1011 are provided with heat insulation curtains 1012, which at least partially cover the drying openings 1011. In order to avoid the transmission mechanism 20 and the battery cells transmitted by it, the heat insulation curtains 1012 are provided with transmission openings. By providing the heat insulation curtains 1012, the drying box 101 can be further isolated from the outside. In the process of the battery cells entering the transfer box 102 through the handling equipment 30, the temperature in the drying component 10 will inevitably be lost, and the gas in the drying component 10 will be exchanged with the external air, resulting in the entry of impurities. Therefore, the heat insulation curtains 1012 can not only reduce the heat loss inside the drying box 101, but also improve the cleanliness inside the drying box 101.

[0048] In actual application, there is a certain distance between the top of the transmission mechanism 20 and the top of the drying component 10, and between the top of the transmission mechanism 20 and the transfer opening 1023, forming a transmission height, which is greater than the height of the flower basket, and the battery cells are installed on the flower basket. By installing the battery cells on the flower basket for processing, the fragmentation rate caused by direct contact between the battery cells and the transmission mechanism 20 can be reduced, and the battery cells can be processed in large quantities through the multiple installation positions set on the flower basket, thereby improving the processing efficiency of the battery cells. Accordingly, the height of the transmission opening opened on the heat insulation curtain 1012 is greater than the height of the transmission mechanism 20 plus the height of the flower basket.

[0049] In one possible implementation, see the attached Figure 5As shown, the drying equipment also includes a cover plate 1021, which is a reversible structure. The cover plate 1021 is connected to the first driving member 1022, and the first driving member 1022 drives the cover plate 1021 to cover or open the top of the transfer box 102, so that the transfer opening 1023 is in an open state or a closed state. Among them, the first driving member 1022 can be a cylinder, and the cylinder drives the cover plate 1021 to rotate by the extension and contraction of its piston rod. Preferably, the cover plate 1021 is flipped from the inside of the transfer box 102 to the outside, so that the cover plate 1021 can be prevented from flipping to the inside of the transfer box 102, causing too much air to enter the transfer box 102. In addition, a handle is also provided on the cover plate 1021, so that the operation and maintenance personnel can open and close the cover plate 1021 by the handle.

[0050] In one possible implementation, see the attached Figure 1 -Attached Fig. 9 As shown, the transmission mechanism 20 has a conveying member 201 and a second driving member 202, the conveying member 201 is connected to the second driving member 202, the second driving member 202 is step-by-step driven, and the conveying member 201 is step-by-step moving, forming a plurality of stop stations 105, and a plurality of heaters 104 are arranged on the drying box 101, and the heaters 104 are located above the conveying member 201, and at least one heater 104 is arranged on each stop station 105. Among them, the conveying member 201 can be a transmission tool such as a roller or a belt, and the conveying member 201 can be driven by the second driving member 202 to drive the flower basket thereon to move. In order to improve the stability of the flower basket during transmission, guide plates can also be arranged on both sides of the conveying member 201, by limiting the moving direction of the flower basket on the conveying member 201, thereby preventing it from falling. By setting the stop station 105, the battery cell can be continuously dried under the heater 104 for a period of time, thereby ensuring that the liquid on the surface of the battery cell can be completely evaporated.

[0051] Furthermore, the heater 104 adopts an electric heating method or a gas heating method. When the heater 104 adopts an electric heating method, the heater 104 includes an electric heating layer, a heat conducting layer arranged on a first surface of the electric heating layer, and a reflective layer arranged on a second surface of the electric heating layer. The first surface and the second surface of the electric heating layer are opposite to each other. The structure of the electric heating layer can be any one of the following:

[0052] (1) The electric heating layer is a unidirectional heat radiation electric heating film;

[0053] (2) The electric heating layer includes a conductive carrier and a unidirectional heat radiation coating coated on the conductive carrier;

[0054] (3) The electric heating layer includes a metal sheet.

[0055] The conductive carrier may include a metal sheet. After the electric heating layer is connected to a power source, it can generate heat radiation in the direction of one side of the heat conducting layer. After the heat radiation passes through the heat conducting layer, it irradiates the battery cell to heat the battery cell. Preferably, the electric heating film is a unidirectional heat radiation electric heating film.

[0056] When the heater 104 adopts gas heating, the heater 104 includes an air storage box, an air pipeline, a blower and the heater 104. The blower is connected to the heater 104 and blows air into the heater 104, so that the air passes evenly from the inside and outside of the spiral heating wire. The heat generated by the heating wire after being energized exchanges heat with the cold air passing through, thereby increasing the wind temperature at the air outlet. The air storage box is connected to the air outlet of the heater 104 to store the generated hot air, and is connected to the drying box 101 through the air pipeline to transport the hot air to the drying box 101.

[0057] Preferably, a filter and a one-way valve are provided on the gas supply pipeline. By providing the filter, impurities can be removed from the hot air formed from the air when it is transported to the drying box 101, thereby ensuring the cleanliness of the inside of the drying box 101. By providing the one-way valve, the movement space of the hot air in the drying box 101 can be reduced, thereby reducing the heat loss in the drying box 101.

[0058] Furthermore, in this manner, a high temperature resistant fan can be provided in the drying box 101, so that the hot air entering the drying box 101 through the air pipeline can be diffused, thereby increasing the heating rate inside the drying box 101 and further improving the processing efficiency of the battery cells.

[0059] Compared with electric heating, gas heating makes it easy for foreign matter to be blown onto the battery cells, causing damage to the battery cells, and easily causes the battery cells to shake, causing the battery cells to fall or wear. Preferably, the heater 104 in the drying equipment adopts electric heating.

[0060] In a feasible implementation, the drying box 101 is divided into at least three temperature zones along the length direction, the heater 104 of each temperature zone is at different heating degrees, and each stop station 105 has a corresponding temperature zone. Since the battery cells enter the drying equipment from the air, in order to avoid a large temperature difference between the inside and outside of the drying equipment, which may affect the processing quality and performance of the battery cells, the temperature of the temperature zone at the transmission start of the drying box 101 will be lower than that of other temperature zones. For example, there are three stop stations 105 in a drying box 101, and the temperatures of the three stop stations 105 increase successively along the transmission path, thus forming three temperature zones. Accordingly, the heaters 104 in different temperature zones will generate different degrees of heat.

[0061] In order to separately regulate the heating degree of multiple heaters 104, the battery cell drying equipment may also include a controller. There is a communication line (wired or wireless communication line) between the heater 104 and the controller. The controller can receive the signal sent by the heater 104, and then regulate the heat generated by the heater 104 so that the multiple stop stations 105 can reach the set temperature range, thereby forming multiple temperature zones in the drying box 101.

[0062] Furthermore, a plurality of temperature sensors may be provided in the drying box 101, the number of temperature sensors being greater than or equal to the number of the stop stations 105, and at least one temperature sensor is provided on each stop station 105, the temperature sensor is electrically connected to the controller, and the controller monitors the real-time temperature of the stop station 105 by receiving the signal sent by the temperature sensor. Since there is a certain distance between each stop station 105, which is the distance formed by the time period during which the second driving member 202 drives the conveying member 201 to rotate, there are differences in the temperature between the plurality of stop stations 105. By providing the temperature sensor, the temperature of the plurality of stop stations 105 may be monitored respectively, and the heater 104 of the stop station 105 may be regulated according to the temperature data. Of course, the optimal temperature range of each stop station 105 may also be pre-set, and when the temperature on the stop station 105 is outside the preset temperature range, the temperature sensor may be fed back to the controller via the above-mentioned communication line, and then the controller issues a reminder in the form of sound, light and electricity.

[0063] For further information, see Appendix Figure 1 -Attached Figure 4 As shown, the drying assembly 10 is also provided with a plurality of viewing windows, and both the transfer box 102 and the drying box 101 can be provided with viewing windows, and each stop station 105 and each transfer box 102 are provided with at least one viewing window. In this way, the processing conditions in the drying assembly 10 can be observed through the viewing windows, so as to adjust the position inside the equipment, improve the processing temperature, etc., so as to achieve better processing effects.

[0064] It can be seen that the battery cell drying equipment provided by the present application divides the drying component 10 into a connected drying box 101 and a transfer box 102. The transfer box 102 has an openable and closable transfer opening 1023, so that the drying equipment can enhance its sealing performance through this structure during the period when the battery cells are not dried, thereby reducing heat loss, improving processing efficiency, improving the internal cleanliness of the drying equipment and reducing costs; in addition, since the transmission device is arranged in the drying component 10, the exposed space of the drying equipment can be further reduced.

[0065] The above are only preferred embodiments of the present application and are not intended to limit the present application.
