[0004] With the advancement of science, breakthroughs have been continuously achieved in the development of new energy sources. Solar cells, represented by perovskite and organic thin-film batteries, have made disruptive progress. These solar cells, due to their high efficiency and low cost, have been widely used in aerospace, industry, commerce, agriculture, and communications. Perovskite solar cells are devices that convert solar energy into electrical energy using the photoelectric conversion mechanism of perovskite crystalline materials. They are currently the third generation of solar cells, possessing advantages such as high photoelectric conversion efficiency, simple manufacturing process, and low production cost, and have been extensively studied in recent years.

[0005] In the development of solar cell technology, how to improve the reliability of solar cells is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This application provides a battery manufacturing apparatus designed to improve the reliability of solar cells to a certain extent.

[0007] In a first aspect, this application proposes a battery production equipment, which includes a support, a conveying mechanism, and a heat exchange component; the conveying mechanism is disposed on the support and is used to receive and convey the substrate; the heat exchange component is disposed on the support and is located on the conveying path of the substrate, and is used to exchange heat with the substrate.

[0008] The battery production equipment provided in this application, by incorporating heat exchange components along the substrate transport path, achieves both normal substrate transport and cooling, reducing the impact of thermal stress on the next process and shortening or eliminating substrate placement time before entering the next process. Furthermore, the substrate transported by the conveying mechanism exhibits a reduced water droplet angle and improved wettability, thereby enhancing the stability of the perovskite layer formation and ultimately improving the reliability of the perovskite solar cell.

[0009] According to one embodiment of this application, heat exchange components are at least disposed on both sides of the conveying mechanism along a first direction, wherein the first direction, the conveying direction of the substrate, and the vertical direction of the support are perpendicular to each other.

[0010] In these alternative embodiments, this configuration increases the area of ​​the heat exchange component and the corresponding region of the substrate, thereby improving heat exchange efficiency.

[0011] According to one embodiment of this application, the conveying mechanism includes a plurality of conveyor belts spaced apart along a first direction, and a heat exchange assembly is further disposed between two adjacent conveyor belts.

[0012] In these alternative embodiments, this configuration increases the density of heat exchange components in the area opposite the substrate, allowing the heat released from the substrate to be quickly transferred to the heat exchange components, resulting in higher heat transfer efficiency and thus improved cooling efficiency.

[0013] According to one embodiment of this application, the heat exchange assembly has a heat exchange plane on its upper side, and the heat exchange plane is configured to adhere to the substrate.

[0014] In these alternative embodiments, the heat exchange component has a heat exchange plane on its upper side, which allows the heat exchange component to have a larger contact area with the substrate, thereby improving heat transfer efficiency.

[0015] According to one embodiment of this application, the heat exchange assembly includes a heat exchange plate, and the heat exchange plate has a flow channel for guiding the flow of the heat exchange medium.

[0016] In these alternative embodiments, the flow channel can guide the flow of the heat exchange medium, which can quickly remove the heat from the substrate and also achieve continuous cooling of the substrate.

[0017] According to one embodiment of this application, the heat exchange plate is made of aluminum or an aluminum alloy.

[0018] In these alternative embodiments, aluminum or aluminum alloys are used as thermally conductive materials, which have good thermal conductivity and facilitate rapid heat dissipation and cooling of the substrate.

[0019] According to one embodiment of this application, the battery production equipment further includes an adsorption element configured to be located on the side of the heat exchange assembly facing the substrate. The adsorption element is connected to the heat exchange assembly and is used to adsorb the substrate.

[0020] In these alternative embodiments, the adsorption element is provided to facilitate stable contact between the heat exchange component and the substrate, and to reduce the gap between the heat exchange component and the substrate, thereby improving the cooling effect. Furthermore, the adsorption element provides a buffering effect, improving direct contact between the substrate and the extremely cold heat exchange component, and providing a buffer for the substrate's cooling process.

[0021] According to one embodiment of this application, the battery production equipment further includes a vacuuming component, which is connected to an adsorption component.

[0022] In these alternative embodiments, an air extraction element is provided to facilitate control of the adsorption or release of the substrate by the adsorbent element.

[0023] According to one embodiment of this application, the adsorption element at least partially protrudes from the heat exchange assembly.

[0024] In these alternative embodiments, the adsorption element protruding from the heat exchange component creates a smaller gap between the substrate and the heat exchange component, thereby improving the effect of the substrate suddenly coming into contact with the extremely cold heat exchange component while achieving a cooling effect, so that the substrate can gradually and stably cool down.

[0025] According to one embodiment of this application, the heat exchange assembly includes a heat exchange plate, and the surface of the heat exchange plate facing the substrate has an inwardly recessed portion, and a portion of the adsorption element is disposed within the recess.

[0026] In these alternative embodiments, a portion of the adsorption element is disposed within the recess, which can further reduce the gap between the heat exchange plate and the substrate, thereby improving heat exchange efficiency and enhancing the cooling effect on the substrate.

[0027] According to one embodiment of this application, the adsorption element is made of polytetrafluoroethylene.

[0028] In these alternative embodiments, the polytetrafluoroethylene (PTFE) adsorbent can effectively reduce the damage to the adsorbent caused by the high-temperature substrate. At the same time, PTFE has hydrophobic and oleophobic properties, which can effectively reduce oil contamination of the substrate.

[0029] According to one embodiment of this application, the battery production equipment further includes a drive unit connected to a heat exchange assembly, which drives the heat exchange assembly to move up and down.

[0030] According to one embodiment of this application, the battery production equipment further includes a temperature detection element disposed on a support, the temperature detection element being used to detect the temperature of the substrate.

[0031] In these alternative embodiments, by providing a driving component, the heat exchange assembly can be raised and lowered, and the heat exchange assembly and the conveying mechanism can operate independently of each other, reducing the interference of the heat exchange assembly on the normal conveying of the substrate on the conveying mechanism.

[0032] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0045] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone.

[0048] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0049] In this application, "multiple" means two or more (including two).

[0050] In perovskite solar cell technologies, a substrate is used as the base, a hole transport layer is formed on the substrate, and after laser processing of the hole transport layer, a perovskite layer is formed on top of the hole transport layer. Typically, the hole transport layer is formed on the substrate using a coating apparatus. After being unloaded from the coating apparatus, the substrate needs to be transported by a conveyor mechanism before laser processing in a laser scribing apparatus. However, the substrate temperature is too high after unloading from the coating apparatus. Due to thermal stress, some lines after laser scribing are bent, thus increasing the dead area. Although the substrate can be naturally cooled after unloading, the cleaning effect after laser scribing is deteriorated, which is not conducive to the formation of the perovskite layer and reduces the reliability of the perovskite solar cell. The above statements are only for providing background information related to this application and do not necessarily constitute prior art.

[0051] In view of the above problems, the battery production equipment provided in this application, by setting up heat exchange components and integrating heat exchange components on the substrate transport path, achieves both normal substrate transport and substrate cooling, reducing the impact of thermal stress on the next process, and shortening or eliminating the substrate placement time before entering the next process. Furthermore, the substrate transported by the conveying mechanism exhibits a reduced water droplet angle and improved wettability, thereby enhancing the stability of the perovskite layer formation and ultimately improving the reliability of the perovskite solar cell.

[0052] This application discloses a battery manufacturing apparatus that can be used to manufacture solar cells, which may be, but are not limited to, perovskite solar cells. Furthermore, the battery disclosed in this application can be used in electrical devices such as vehicles, ships, or aircraft. A power system incorporating the battery disclosed in this application can be used to construct such an electrical device.

[0053] Referring to Figure 1, Figure 1 is a schematic diagram of a structure provided in an embodiment of this application.

[0054] As shown in Figure 1, this application proposes a battery production equipment 100, which includes a support 10, a conveying mechanism 20, and a heat exchange assembly 30. The conveying mechanism 20 is disposed on the support 10 and is used to receive and convey the substrate 1. The heat exchange assembly 30 is disposed on the support 10 and located on the conveying path of the substrate 1, and is used to exchange heat with the substrate 1.

[0055] To ensure that the solar cell has a certain structural strength, the solar cell uses substrate 1 as the base, and other layers, such as the transport layer, are disposed on substrate 1.

[0056] The substrate 1 can also be called a substrate. The material of the substrate 1 can be, but is not limited to, glass, tempered glass, quartz, organic flexible materials, etc.; of course, it can also be transparent conductive glass, stainless steel conductive flexible substrate, polyethylene terephthalate (PET) conductive flexible substrate, etc.

[0057] Specifically, the battery production equipment 100 also includes a coating device, and the substrate 1 is placed in the conveying mechanism 20 for transfer to the next process after being unloaded from the coating device.

[0058] The support 10 serves as a basic component of the battery production equipment 100, used to install and support other components, such as the conveying mechanism 20 and the heat exchange assembly 30. The support 10 can have various shapes, including regular shapes such as cuboids, cubes, and cylinders, as well as other irregular shapes. The shape of the support 10 should not affect the normal conveying function of the conveying mechanism 20 or the cooling of the substrate 1 by the heat exchange assembly 30. This application does not limit the specific shape of the support 10. The support 10 can also be made of various materials, such as steel, aluminum alloy, or other composite materials.

[0059] The conveying mechanism 20 is used to receive the substrate 1 and convey the substrate 1 to the downstream device.

[0060] In the embodiments of this application, the conveying mechanism 20 may include one or more conveying channels. In the case of multiple conveying channels, the conveying paths of each conveying channel may be the same or different, so as to realize the synchronous conveying of multiple substrates 1 and speed up the conveying of multiple substrates 1.

[0061] For example, the conveying mechanism 20 may include gear drive, chain drive, belt drive, shaft drive, etc.

[0062] The heat exchange component 30 is used to exchange heat with the substrate 1 in order to regulate the temperature.

[0063] Specifically, the heat exchange component 30 is located on the transport path of the substrate 1 and performs heat exchange on the substrate 1 on the transport mechanism 20. The heat exchange component 30 can be fixed to the support 10 to cool the substrate 1 passing through it; or, the heat exchange component 30 can be movably disposed on the support 10 to move along the transport path of the substrate 1, thereby continuously cooling the substrate 1 on the transport mechanism 20; or, the heat exchange component 30 can be temporarily attached to the surface of the substrate 1 to cool it, in which case the substrate 1 can be temporarily stationary or in motion.

[0064] For example, the heat exchange assembly 30 uses a heat exchange pipeline to guide the flow of the heat exchange medium. The heat exchange medium flowing in the heat exchange pipeline can quickly remove heat.

[0065] For example, the heat exchange assembly 30 employs a surface cooler.

[0066] The battery production equipment 100 provided in this application, by setting up a heat exchange component 30 and integrating the heat exchange component 30 on the transport path of the substrate 1, achieves both normal transport of the substrate 1 and cooling of the substrate 1, reducing the impact of thermal stress on the next process, and shortening or eliminating the placement time of the substrate 1 before entering the next process. Moreover, after being transported by the transport mechanism 20, the water droplet angle of the substrate 1 is reduced, and the wettability of the substrate 1 is improved, thereby improving the stability of the perovskite layer formation and thus improving the reliability of the perovskite solar cell.

[0067] Referring to Figures 2 and 3, Figure 2 is a structural schematic diagram of a battery production equipment provided in an embodiment of this application; Figure 3 is a front view of a battery production equipment provided in an embodiment of this application.

[0068] According to one embodiment of this application, as shown in Figures 2 and 3, the heat exchange assembly 30 is disposed on at least two sides of the conveying mechanism 20 along the first direction x, wherein the first direction x, the conveying direction y of the substrate 1, and the vertical direction z of the support 10 are perpendicular to each other.

[0069] In an embodiment of this application, the battery production equipment 100 includes at least two heat exchange components 30, which are respectively disposed on both sides of the conveying mechanism 20 along the first direction x.

[0070] Specifically, the projection of the conveying mechanism 20 along the vertical direction z of the support 10 falls into the substrate 1. This can be understood as the area of ​​the conveying mechanism 20 being smaller than the area of ​​the substrate 1, in order to increase the contact area or overlap area between the heat exchange component 30 and the substrate 1, thereby increasing the heat exchange area.

[0071] Optionally, along the vertical z-direction of the support 10, the heat exchange assembly 30 at least partially overlaps with the substrate 1.

[0072] In these alternative embodiments, this configuration increases the area of ​​the heat exchange component 30 corresponding to the substrate 1, thereby improving heat exchange efficiency.

[0073] According to one embodiment of this application, the conveying mechanism 20 includes a plurality of conveyor belts 21 spaced apart along a first direction x, and a heat exchange assembly 30 is also disposed between two adjacent conveyor belts 21.

[0074] Specifically, the conveying mechanism 20 includes N conveyor belts 21 spaced apart along the first direction x. The battery production equipment 100 includes N+1 conveying mechanisms 20. Each conveyor belt 21 has a conveying mechanism 20 on both sides along the first direction x. This can be understood as the conveyor belts 21 and the heat exchange assembly 30 being staggered along the first direction x. Each conveyor belt 21 can individually convey one substrate 1, or multiple conveyor belts 21 can jointly convey one substrate 1.

[0075] For example, the conveying mechanism 20 includes a first conveyor belt and a second conveyor belt spaced apart along a first direction x, and the substrate 1 is configured to be conveyed on the first conveyor belt and the second conveyor belt. The conveying mechanism 20 also includes a first heat exchange component, a second heat exchange component, and a third heat exchange component spaced apart along the first direction x, the first heat exchange component and the second heat exchange component being disposed on both sides of the first conveyor belt along the first direction x, and the second heat exchange component and the third heat exchange component being disposed on both sides of the second conveyor belt along the first direction x.

[0076] Optionally, the conveying mechanism 20 extends along the conveying direction y of the substrate 1.

[0077] In these alternative embodiments, this configuration increases the density of the heat exchange components 30 in the region opposite to the substrate 1, allowing the heat released from the substrate 1 to be quickly transferred to the heat exchange components 30, resulting in higher heat transfer efficiency and thus improved cooling efficiency.

[0078] According to one embodiment of this application, as shown in Figures 2 and 3, the heat exchange assembly 30 has a heat exchange plane 31 on its upper side, and the heat exchange plane 31 is configured to adhere to the substrate 1.

[0079] In the embodiments of this application, the heat exchange component 30 has a heat exchange plane 31 on its upper side, which can be attached to the substrate 1 to increase the contact area between the heat exchange component 30 and the substrate 1. Optionally, during the process of attaching the heat exchange plane 31 of the heat exchange component 30 to the substrate 1, the substrate 1 can be paused in its transport. After the temperature of the substrate 1 drops to a preset temperature, the heat exchange component 30 separates from the substrate 1, and the transport mechanism 20 continues to transport the substrate 1.

[0080] Optionally, the substrate 1 has a first surface and a second surface opposite each other along the thickness direction, the second surface is located on the lower side and is planar, and the heat exchange plane 31 on the upper side of the heat exchange assembly 30 is attached to the second surface.

[0081] In these alternative embodiments, the heat exchange component 30 has a heat exchange plane 31 on its upper side, so that the heat exchange component 30 and the substrate 1 have a large contact area, thereby improving the heat transfer efficiency.

[0082] According to one embodiment of this application, the heat exchange assembly 30 includes a heat exchange plate 32, and the heat exchange plate 32 is provided with a flow channel 321 for guiding the flow of the heat exchange medium.

[0083] The heat exchange plate 32 has a flow channel 321 inside, which is used to guide the flow of the heat exchange medium. The heat exchange medium flowing in the flow channel 321 can quickly remove the heat from the substrate 1. The heat exchange medium is a fluid medium, such as water, ethanol, oil and Freon. The heat exchange medium can absorb the heat from the substrate 1, or the flowing heat exchange medium can carry the heat from the substrate 1 to the external environment to achieve the purpose of cooling.

[0084] For example, the heat exchange plate 32 includes a first plate body and a second plate body, which are stacked along the thickness direction of the heat exchange plate 32. The first plate body is provided with a flow guide groove, and the second plate body has a first surface and a second surface disposed opposite to each other along the thickness direction. The first surface is used to contact the substrate 1, and the second surface is connected to the first plate body and covers the flow guide groove to form a flow channel 321. With this configuration, the flow guide groove can be directly processed and manufactured on the semi-finished first plate body, simplifying the structure of the flow channel 321.

[0085] In some embodiments, the flow channel 321 may be wavy, toothed, S-shaped, etc.

[0086] Optionally, the heat exchange assembly 30 includes a heat exchange plate 32, the surface of which facing the substrate 1 is planar.

[0087] In these alternative embodiments, the flow channel 321 can guide the flow of the heat exchange medium, which can quickly remove the heat from the substrate 1 and also achieve continuous cooling of the substrate 1.

[0088] According to one embodiment of this application, the heat exchange assembly 30 further includes a connector disposed on the heat exchange plate 32 and communicating with the flow channel 321.

[0089] In this embodiment, the heat exchange assembly 30 includes a heat exchange plate 32 and a connector. The heat exchange plate 32 is provided with a flow channel 321. The connector is disposed on the heat exchange plate 32 and communicates with the flow channel 321. The flowing heat exchange medium flows into or out of the flow channel 321 through the connector. The heat exchange medium flows in the flow channel 321 and absorbs a portion of the heat through heat exchange, thereby achieving cooling of the substrate 1.

[0090] For example, the heat exchange assembly 30 includes a connector through which heat exchange medium can be introduced into the flow channel 321, and through which heat exchange medium can be exported from the flow channel 321.

[0091] For example, the heat exchange assembly 30 includes a plurality of connectors, at least one of which is used to guide the heat exchange medium into the flow channel 321, and at least one connector is used to discharge the heat exchange medium in the flow channel 321. The plurality of connectors may be disposed at one end of the heat exchange plate 32, or the plurality of connectors may be disposed at both ends of the heat exchange plate 32 respectively.

[0092] In these alternative embodiments, the connector is attached to the heat exchange plate 32, facilitating its installation and removal with minimal alteration to the overall structure of the heat exchange plate 32. Furthermore, the connector allows for continuous flow of the heat exchange medium, thus enabling sustained heat dissipation.

[0093] According to one embodiment of this application, the heat exchange plate 32 is made of aluminum or an aluminum alloy.

[0094] In these alternative embodiments, aluminum or aluminum alloy is used as a thermally conductive material, which has good thermal conductivity and is beneficial for the rapid heat dissipation and cooling of the substrate 1.

[0095] Referring to Figures 4 and 5, Figure 4 is a structural schematic diagram of a battery production equipment provided in another embodiment of this application; Figure 5 is a structural schematic diagram of a heat exchange component of a battery production equipment provided in an embodiment of this application.

[0096] According to one embodiment of this application, as shown in Figures 4 and 5, the battery production equipment 100 further includes an adsorption member 40, which is configured to be located on the side of the heat exchange assembly 30 facing the substrate 1. The adsorption member 40 is connected to the heat exchange assembly 30 and is used to adsorb the substrate 1.

[0097] In embodiments of this application, the battery production equipment 100 further includes an adsorption member 40, which is disposed on the side of the heat exchange assembly 30 facing the substrate 1. The adsorption member 40 adsorbs the substrate 1, allowing the heat exchange assembly 30 to connect with the substrate 1 and cool the substrate 1 via the adsorption member 40. When the substrate 1 is transported to a predetermined position on the conveying mechanism 20 or when the substrate 1 is disposed on the conveying mechanism 20, the heat exchange assembly 30 adheres to the substrate 1 via the adsorption member 40 to cool the substrate 1. After the substrate 1 is cooled to a preset temperature, the adsorption of the adsorption member 40 is released, separating the heat exchange assembly 30 from the substrate 1.

[0098] Optionally, the adsorption component 40 can be adsorbed onto the substrate 1 using a suction cup, tape, or electrostatic component.

[0099] The battery manufacturing equipment 100 includes one or more adsorption elements 40. When the battery manufacturing equipment 100 includes multiple adsorption elements 40, the multiple adsorption elements 40 are spaced apart along the transport direction y on the heat exchange assembly 30, so that the substrate 1 and the heat exchange assembly 30 are in closer contact.

[0100] In these alternative embodiments, the adsorption member 40 is provided to facilitate stable contact between the heat exchange component 30 and the substrate 1, and to reduce the gap between the heat exchange component 30 and the substrate 1, thereby improving the cooling effect. In addition, the adsorption member 40 has a certain buffering effect, which can improve the direct contact between the substrate 1 and the extremely cold heat exchange component 30, and provide a certain buffer for the cooling of the substrate 1.

[0101] According to one embodiment of this application, the battery production equipment 100 further includes a vacuum member 50, which is connected to the adsorption member 40.

[0102] In these alternative embodiments, as shown in FIG4, the suction element 50 is provided to facilitate control of the adsorption element 40 adsorbing or releasing the substrate 1.

[0103] According to one embodiment of this application, the adsorption member 40 protrudes at least partially from the heat exchange assembly 30.

[0104] In the embodiments of this application, the adsorption member 40 is disposed on the side of the heat exchange component 30 facing the substrate 1, and the adsorption member 40 protrudes at least partially from the heat exchange component 30, so that the adsorption member 40 first adsorbs onto the lower surface of the substrate 1. The adsorption member 40 protruding from the heat exchange component 30 makes the substrate 1 and the heat exchange component 30 have a small gap, thereby improving the situation where the substrate 1 suddenly comes into contact with the extremely cold heat exchange component 30 while achieving the cooling effect, so that the substrate 1 can gradually and stably cool down.

[0105] Optionally, the adsorption element 40 is a suction cup.

[0106] According to one embodiment of this application, as shown in Figures 4 and 5, the heat exchange assembly 30 includes a heat exchange plate 32. The surface of the heat exchange plate 32 facing the substrate 1 is provided with an inwardly recessed portion 322, and a portion of the adsorption member 40 is disposed in the recess 322.

[0107] Specifically, the heat exchange assembly 30 includes a heat exchange plate 32, which has a first surface and a second surface along the thickness direction. The first surface faces the substrate 1 and has an inwardly recessed portion 322. A portion of the adsorption member 40 is disposed in the recess 322 and another portion protrudes from the first surface.

[0108] In these alternative embodiments, a portion of the adsorption member 40 is disposed within the recess 322, which can further reduce the gap between the heat exchange plate 32 and the substrate 1, thereby improving the heat exchange efficiency and the cooling effect on the substrate 1.

[0109] According to one embodiment of this application, the absorbent element 40 is made of polytetrafluoroethylene.

[0110] In these alternative embodiments, the polytetrafluoroethylene (PTFE) adsorbent 40 can effectively reduce the damage to the adsorbent 40 caused by the high temperature of the substrate 1. At the same time, PTFE has hydrophobic and oleophobic properties, which can effectively reduce oil contamination of the substrate 1.

[0111] According to one embodiment of this application, as shown in Figures 4 and 5, the battery production equipment 100 further includes a drive member 60, which is connected to the heat exchange assembly 30 and drives the heat exchange assembly 30 to move up and down.

[0112] In the embodiments of this application, the battery production equipment 100 further includes a driving component 60, which can be disposed on the support 10 and move up and down relative to the support 10. The driving component 60 is connected to the heat exchange assembly 30 to drive the heat exchange assembly 30 to rise and fall, thereby controlling the heat exchange assembly 30 to achieve the bonding and separation of the heat exchange assembly 30 from the substrate 1.

[0113] Specifically, after the conveying mechanism 20 receives the substrate 1 or after the substrate 1 is conveyed to a predetermined position, the driving member 60 drives the heat exchange assembly 30 to rise, so that the heat exchange assembly 30 is in contact with the substrate 1 to exchange heat with the substrate 1. After the substrate 1 drops to a preset temperature, the driving member 60 drives the heat exchange assembly 30 to descend, and the conveying mechanism 20 conveys the substrate 1 to the next process.

[0114] The drive unit 60 uses servo electrodes, cylinders, hydraulic cylinders, etc.

[0115] Optionally, the drive unit 60 is a lifting cylinder.

[0116] In these alternative embodiments, by providing a drive member 60, the heat exchange assembly 30 is raised and lowered, and the heat exchange assembly 30 and the conveying mechanism 20 operate independently of each other, reducing the interference of the heat exchange assembly 30 on the normal conveying of the substrate 1 on the conveying mechanism 20.

[0117] According to one embodiment of this application, as shown in FIG2, the battery production equipment 100 further includes a temperature detection element 70 disposed on the support 10, and the temperature detection element 70 is used to detect the temperature of the substrate 1.

[0118] Optionally, the temperature sensing element 70 includes a temperature sensor.

[0119] In these alternative embodiments, by setting a temperature detection element 70, the cooling effect of the heat exchange component 30 can be detected in real time, reducing the problem of cooling failure of the substrate 1 caused by abnormality of the heat exchange component 30.

[0120] A battery production apparatus includes a support frame, a conveying mechanism, a heat exchange assembly, an adsorption component, a vacuum component, a drive component, and a temperature detection component. The apparatus also includes a coating unit, with the support frame located downstream of the coating unit.

[0121] A conveying mechanism is mounted on a support and is used to receive and transport the substrate. The conveying mechanism includes two conveyor belts spaced apart along a first direction. A heat exchange assembly is disposed on both sides of the conveying mechanism along the first direction, and the heat exchange assembly is also disposed between two adjacent conveyor belts. The first direction, the substrate transport direction, and the vertical direction of the support are perpendicular to each other.

[0122] The heat exchange assembly is movably mounted on the support and located on the transport path of the substrate. The heat exchange assembly is used for heat exchange with the substrate. The heat exchange assembly includes a heat exchange plate with flow channels within it to guide the flow of the heat exchange medium. The surface of the heat exchange plate facing the substrate has an inwardly recessed portion. The heat exchange plate is made of aluminum alloy.

[0123] The adsorbent is configured to be located on the side of the heat exchange assembly facing the substrate, with a portion of the adsorbent disposed within a recess and another portion protruding from the heat exchange assembly. The adsorbent is connected to the heat exchange assembly and is used to adsorb the lower surface of the substrate. The adsorbent is made of polytetrafluoroethylene (PTFE).

[0124] The extraction component is connected to the adsorption component.

[0125] The drive unit is connected to the heat exchange assembly, and drives the heat exchange assembly to rise and fall.

[0126] A temperature sensor is mounted on the support and is used to detect the temperature of the substrate.

[0127] Temperature and water droplet angle tests are performed on the substrates after they have passed through the battery production equipment. Temperature testing uses an infrared thermometer to measure the temperature of the upper and lower surfaces of the substrate at regular intervals. Water droplet angle testing uses a water droplet angle meter to measure the water droplet angle of the substrate; the size of the water droplet angle reflects the wettability of the substrate.

[0128] The test results are shown in Figures 6 and 7. In Figure 6, the upper curve represents the cooling curve of the upper surface of the substrate, and the lower curve represents the cooling curve of the lower surface of the substrate. As shown in Figure 6, after the high-temperature substrate treated by the coating device is cooled by the heat exchange component, the temperature of both the upper and lower surfaces of the substrate reaches room temperature after 150 seconds of heat exchange component operation, with the lower surface cooling down more significantly. In Figure 7, the upper curve represents the water droplet angle curve of the substrate without heat exchange component treatment, and the lower curve represents the water droplet angle curve of the substrate after 90 seconds of heat exchange component treatment. As shown in Figure 7, the water droplet angle values ​​of the lower surface of the substrate are reduced in both the substrate treated with the heat exchange component for 90 seconds and the substrate without heat exchange component treatment. Furthermore, the overall change in the water droplet angle value of the lower surface of the substrate is small with the extension of the resting time, thus improving the wettability.
