Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery processing device. Background Art

[0002] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0003] During the battery processing, it is often necessary to conduct tests to confirm whether the entire processing meets the requirements. In addition, the test data can be used to adjust various process parameters, which helps to optimize the processing quality. Therefore, how to effectively improve the detection effect during the battery processing is a technical issue that needs to be continuously improved in battery technology. Utility Model Content

[0004] In view of the above problems, the present application provides a battery processing device that can effectively improve the detection effect during the battery processing.

[0005] The embodiment of the present application provides a battery processing device, which includes a housing, a detection component and a processor. The housing has a receiving cavity, and the receiving cavity is used to receive a film to be processed. The detection component is connected to the housing, and the detection component includes a light source and a receiving component. The light source is used to emit light to the first surface of the film to be processed to excite the film to be processed to produce fluorescence, and the output light path of the light source is approximately perpendicular to the first surface. The receiving component is used to receive the fluorescence, and the receiving component is configured to receive the fluorescence emitted approximately perpendicular to the first surface. The processor is connected to the receiving component and is used to generate processing information according to the fluorescence received by the receiving component.

[0006] The light path of the light source of the above technical solution is roughly perpendicular to the first surface, so that the energy of the light is more concentrated, the penetration depth and the absorption process are more uniform, and the uniform and deep excitation helps to form a larger and more stable excitation volume inside the film to be processed, which can increase the duration of the fluorescence peak. In this way, the receiving element can obtain stable and reliable fluorescence for a longer time, so as to more accurately reflect the relevant state data of the film to be processed during the processing process, thereby effectively improving the detection effect during the battery processing process.

[0007] In some embodiments, the detection component further includes a base, the base is connected to the box, and the light source and the receiving element are both connected to the base.

[0008] The above technical solution introduces a base and simultaneously connects and fixes the light source and the receiver, which not only improves the stability of the light source and the receiver, but also integrates the light source and the receiver into one. The light source and the receiver can be quickly installed or replaced through the connection points on the base, thereby reducing assembly time and maintenance costs.

[0009] In some embodiments, the light source and the receiving element are disposed on the same side of the film to be processed.

[0010] By placing the light source and the receiver on the same side, the light propagation path is shortened and the signal loss is reduced, thereby improving the detection sensitivity and accuracy of the signal. In addition, the light source and the receiver are placed on the same side, which makes the assembly and alignment operations easier and reduces the complexity of adjusting optical components in different directions.

[0011] In some embodiments, there are multiple detection components, and the light sources of the multiple detection components are configured to emit light of different wavelengths.

[0012] The above technical solution introduces multiple detection components, and the light source of each detection component can emit light of different wavelengths, so as to detect relevant status data of different depths of the membrane to be processed, thereby effectively improving the detection accuracy and breadth during the battery processing process.

[0013] In some embodiments, the detection component is configured to be movable relative to the housing.

[0014] The above technical solution can cover the entire detection area of ​​the membrane to be processed by the mobile configuration of the detection component, thereby improving the comprehensiveness of the detection. Moreover, for membranes of different specifications, the detection component can be adapted by adjusting the position without reinstalling or replacing new detection components, thereby improving the versatility and adaptability of the battery processing device. In addition, since the detection component can flexibly adjust the position and angle, the irradiation area of ​​the light source and the fluorescence collection range of the receiver can be more accurately controlled, which helps to reduce errors and improve detection accuracy.

[0015] In some embodiments, the battery processing device further includes a driving component, which is connected to the detection component and is used to drive the detection component to move.

[0016] The above technical solution can reduce manual intervention in adjusting the position of the detection equipment and improve the degree of automation of the battery processing device by introducing a driving component.

[0017] In some embodiments, the box includes a first wall, a first channel is formed on the first wall, and the first channel penetrates the first wall along the thickness direction of the first wall. The detection component is arranged outside the box and is configured to be arranged opposite to the first channel along the thickness direction. The battery processing device also includes a light-transmitting component, which is sealed and connected to the first wall and covers the first channel.

[0018] The above technical solution can not only reduce the impact of the detection component on the processing environment inside the box by arranging the detection component outside the box, but also facilitate the installation and maintenance of the detection component. In addition, this design makes the detection component relatively independent from the box structure, facilitates modular design, and improves the compatibility and scalability of the equipment.

[0019] In some embodiments, there are multiple first channels, and the multiple first channels are spaced apart along a direction perpendicular to the thickness direction.

[0020] The above technical solution realizes multi-point detection by opening a plurality of first channels at different positions of the box body, thereby being able to obtain more comprehensive detection data and improve the stability and accuracy of the detection.

[0021] In some embodiments, there are multiple light-transmitting components, and the multiple light-transmitting components are arranged in one-to-one correspondence with the multiple first channels, which can improve the material utilization rate of the light-transmitting components, reduce the volume of a single light-transmitting component, facilitate installation and removal, and help reduce costs.

[0022] In some embodiments, the light-transmitting component is detachably connected to the first wall, so that maintenance personnel can conveniently disassemble and replace the light-transmitting component, thereby improving the convenience of using the battery processing device.

[0023] In some embodiments, the battery processing device further includes a first heating component, the first heating component is used to heat the film to be processed, the first heating component is arranged in the accommodating cavity, and is located between the first wall and the film to be processed. A second channel is opened on the first heating component, the second channel passes through the first heating component along the thickness direction, and the second channel at least partially overlaps with the first channel along the thickness direction.

[0024] The above technical solution helps to improve the processing quality of the film to be processed by introducing the first heating component. In addition, by opening a second channel on the first heating component and aligning it with the first channel, the light path can smoothly pass through the heating component, reducing the influence of the heating component on the detection, and improving the accuracy of the detection data.

[0025] In some embodiments, the battery processing device further includes a second heating component, which is disposed on a side of the film to be processed that is away from the first heating component, and is used to support and heat the film to be processed.

[0026] The above technical solution further introduces a second heating component to achieve double-sided heating, so that the film to be processed can be heated more evenly, thereby helping to improve processing quality and production efficiency. In addition, the second heating component can also serve as a carrier for the film to be processed, which helps to reduce the overall structural complexity of the battery processing device.

[0027] In some embodiments, the battery processing device further includes a moving mechanism, which is disposed on the side of the first wall facing away from the accommodating cavity. The moving mechanism includes a connecting member and a first moving member, the connecting member is fixed to the first wall, the first moving member is movably connected to the connecting member, and is configured to be able to move in a first direction relative to the connecting member. The detection component is movably connected to the first moving member, and is configured to be able to move in a second direction relative to the first moving member, and the first direction, the second direction, and the thickness direction are perpendicular to each other.

[0028] The above technical solution realizes the mobile setting of the detection component by introducing a moving mechanism, has a simple structure, is easy to maintain, and helps to reduce costs.

[0029] In some embodiments, the moving mechanism further comprises a second moving member, the second moving member is movably connected to the first moving member and is configured to be able to move along the second direction relative to the first moving member. The detection component is movably connected to the second moving member and is configured to be able to move along the thickness direction relative to the second moving member.

[0030] The above technical scheme can conveniently realize the movement setting of the detection component in three-dimensional space by further introducing a second movable part. At the same time, without changing the detection component, the movement of the detection component along the thickness direction can be used to adjust the size of the light spot emitted by the light source to the first surface, thereby changing the light intensity per unit area to reduce the risk of damaging the membrane to be processed due to excessive light.

[0031] In some embodiments, the moving mechanism also includes a first locking member, which is connected between the connecting member and the first moving member, and is used to lock or unlock the first moving member; and / or, the moving mechanism also includes a second locking member, which is connected between the first moving member and the second moving member, and is used to lock or unlock the second moving member; and / or, the moving mechanism also includes a third locking member, which is connected between the second moving member and the detection component, and is used to lock or unlock the detection component.

[0032] The above technical solution can reduce the risk of vibration or shaking of the detection component during the detection process, thereby improving the detection stability.

[0033] In some embodiments, the battery processing device further includes a vacuum pump, which is connected to the receiving chamber and is used to evacuate the receiving chamber to improve the processing quality.

[0057] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0058] For example, solar cells represented by perovskite and organic thin-film batteries have made disruptive progress, and these solar cells have been widely used in aerospace, industry, commerce, agriculture, and communications due to their advantages of high efficiency and low cost. Among them, perovskite solar cells are devices that convert solar energy into electrical energy using the photoelectric conversion mechanism of perovskite-type crystal materials. They are the current third-generation solar cells, which have many advantages such as high photoelectric conversion efficiency, simple manufacturing process, and low production cost, and have been extensively studied in recent years.

[0059] During the battery processing, it is often necessary to conduct tests to confirm whether the entire processing meets the requirements. In addition, the test data can be used to adjust various process parameters, which helps to optimize the processing quality. Therefore, how to effectively improve the detection effect during the battery processing is a technical issue that needs to be continuously improved in battery technology.

[0060] For example, in the production process of perovskite solar cells, after the substrate has been coated, a layer of perovskite wet film will be formed on the surface of the substrate, and then the substrate will be sent to the crystallization device to promote the rapid crystallization and drying of the perovskite. If there is no effective monitoring method for the crystallization process of perovskite, it will be difficult to find out the useful information contained in the crystallization process of perovskite, and it will be impossible to study the crystallization mechanism and improve the crystallization process.

[0061] In the related art, the fluorescence in-situ technique is used to detect perovskite thin films, but generally the fluorescence peak duration is short, resulting in poor detection effect. The above statements are only used to provide background information related to the present application, and do not necessarily constitute prior art.

[0062] In view of this, an embodiment of the present application provides a battery processing device, which includes a housing, a detection component and a processor, wherein the housing has a receiving cavity, and the receiving cavity is used to receive a film to be processed. The detection component is connected to the housing, and the detection component includes a light source and a receiving component, wherein the light source is used to emit light to the first surface of the film to be processed to excite the film to be processed to generate fluorescence, and the light path of the light source is substantially perpendicular to the first surface, and the receiving component is used to receive the fluorescence. The processor is connected to the receiving component, and is used to generate processing information according to the fluorescence received by the receiving component.

[0063] The light path of the light source is roughly perpendicular to the first surface, so that the energy of the light is more concentrated, the penetration depth and the absorption process are more uniform, and the uniform and deep excitation helps to form a larger and more stable excitation volume inside the film to be processed, which can increase the duration of the fluorescence peak. In this way, the receiving element can obtain stable and reliable fluorescence for a longer time, so as to more accurately reflect the relevant state data of the film to be processed during the processing process, thereby effectively improving the detection effect during the battery processing process.

Figure 2 A schematic cross-sectional structure diagram of a battery processing device provided in some embodiments of the present application.

[0065] Continue to refer Figure 1 to Figure 2 The embodiment of the present application provides a battery processing device, which includes a housing 10, a detection component 20 and a processor 30. The housing 10 has a receiving cavity 11, and the receiving cavity 11 is used to receive a film to be processed 100. The detection component 20 is connected to the housing 10, and the detection component 20 includes a light source 21 and a receiving component 22. The light source 21 is used to emit light to the first surface 110 of the film to be processed 100 to stimulate the film to be processed 100 to generate fluorescence, and the outgoing light path of the light source 21 is substantially perpendicular to the first surface 110, and the receiving component 22 is used to receive the fluorescence. The processor 30 is connected to the receiving component 22, and is used to generate processing information according to the fluorescence received by the receiving component 22.

[0066] An embodiment of the present application provides a battery processing device, which can be used to process relevant components in a battery.

[0067] As an example, the battery processing device can be used to crystallize the perovskite film in the perovskite solar cell. Specifically, in the production process of the perovskite film, it is necessary to first provide a substrate, and then coat the substrate surface to form a layer of perovskite wet film on the substrate surface, and then send the substrate to the battery processing device to promote the rapid crystallization and drying of the perovskite. The detection component 20 and the processor 30 can detect the crystallization process of the perovskite to explore the useful information contained in the perovskite crystallization process, facilitate the study of the crystallization mechanism and improve the crystallization process.

[0068] As another example, the cell processing apparatus may also be used to crystallize an organic thin film film in an organic thin film solar cell, wherein the organic thin film may be, but is not limited to, a direct bandgap semiconductor material including cadmium telluride or copper indium gallium selenide.

[0069] It is understandable that for the sake of simplicity, the embodiments of the present application only use the example of using a battery processing device to crystallize a perovskite film in a perovskite solar cell, but it should be understood that the present application is not limited to this, and can also be applied to other occasions where the relevant status data of the film 100 to be processed during the processing process can be detected by photoluminescence technology, and protection can be provided.

[0070] The box 10 is used to provide a processing environment for the to-be-processed membrane 100. As an example, the box 10 has a sealed accommodating cavity 11, which is convenient for adjusting to form a specific processing environment.

[0071] Optionally, the housing 10 may be made of, but is not limited to, stainless steel.

[0072] In some examples, the battery processing device further includes a carrier, which is disposed in the accommodating cavity 11 and connected to the box body 10 , and is used to carry the membrane 100 to be processed.

[0073] The detection component 20 can be detachably connected to the box body 10, or can be integrally arranged on the box body 10. The detection component 20 can be directly connected to the box body 10, or can be restricted on the box body 10 by other components.

[0074] The detection component 20 may be fixedly connected to the box body 10 , or movably connected to the box body 10 .

[0075] The detection component 20 may be disposed in the accommodating cavity 11 or outside the box body 10 .

[0076] The light source 21 and the receiving element 22 may be arranged separately or integrated into one. For example, the light source 21 and the receiving element 22 are arranged separately, which means that the light source 21 and the receiving element 22 are two independent components that are not connected to each other; the light source 21 and the receiving element 22 are integrated into one, which means that the light source 21 and the receiving element 22 are directly or indirectly connected.

[0077] Optionally, the light source 21 may be a light emitting diode, a laser generator, a xenon lamp, etc.

[0078] As an example, a light emitting diode is used as the light source 21 . The light emitting diode has the characteristics of high efficiency, long life and low heat release.

[0079] The receiving element 22 is responsible for receiving the fluorescence generated by the film 100 to be processed, and converting it into an electrical signal to transmit to the processor 30. Optionally, the receiving element 22 can be, but is not limited to, a photodiode, a photomultiplier tube, an optical fiber probe combined with a photodetector, etc., which can quickly respond to the fluorescence generated on the film 100 to be processed and accurately transmit it to the processor 30.

[0080] Exemplarily, the angle between the outgoing light path of the light source 21 and the first surface 110 will affect the duration of the fluorescence peak of the fluorescence generated by the film to be processed 100. The outgoing light path of the light source 21 is roughly perpendicular to the first surface 110, so that the energy of the light is more concentrated, the penetration depth and the absorption process are more uniform, and the uniform and deep excitation helps to form a larger and more stable excitation volume inside the film to be processed 100, which can increase the duration of the fluorescence peak. When the outgoing light path of the light source 21 is obliquely incident on the film to be processed 100, the path of the light beam propagating in the film to be processed 100 becomes longer, which can easily make the excited fluorescence area become uneven, and part of the energy of the fluorescence may be weakened due to reflection, scattering or interface loss, resulting in a smaller or unstable excitation volume, thereby shortening the duration of the fluorescence peak.

[0081] In addition, when the output light path of the light source 21 is approximately perpendicular to the first surface 110, the excited fluorescent area is relatively uniform, and the competition of the non-radiative channel is relatively weak, so that the duration of the fluorescence peak is relatively long; when the output light path of the light source 21 is obliquely incident on the film 100 to be processed, the unevenness of the excited fluorescent area will enhance the non-radiative recombination, causing the fluorescence decay to accelerate.

[0082] It should be noted that the fact that the outgoing light path of the light source 21 is approximately perpendicular to the first surface 110 means that the angle between the outgoing light path of the light source 21 and the first surface 110 is not limited to a strict 90° relationship, and the angle between the outgoing light path of the light source 21 and the first surface 110 is within the approximately perpendicular limit range of the present application in the range of 80°-100°.

[0083] The processor 30 is responsible for converting the fluorescence received by the receiving element 22 into processing information that can be used for analysis. The processor 30 may include a high-speed computing module and a data processing module, and generates state data about the film 100 to be processed, i.e., the above-mentioned processing information, by analyzing the intensity and spectrum of the fluorescence.

[0084] As an example, in the case where the battery processing device is used to crystallize the perovskite film in the perovskite solar cell, the perovskite material has specific fluorescence characteristics during the crystallization process. The uncrystallized or low-crystallization perovskite film usually emits a weak fluorescence signal, and its emission wavelength and intensity are unstable. When the crystallization process is in progress, as the crystal grows and the structure improves, the fluorescence characteristics of the material will change significantly: the intensity of the fluorescence will usually increase, and may be accompanied by changes in the fluorescence peak position. This is because during the crystallization process, the crystal structure is gradually formed, and the lattice defects are reduced, resulting in changes in the recombination pathway of the photoexcited state, thereby affecting the emission characteristics of the fluorescence.

[0085] During the crystallization process of the perovskite film, the crystallinity of the material increases, the grains gradually grow, the defects inside the crystal decrease, the chances of electron recombination increase, and more electrons and holes can effectively combine and emit fluorescence, thereby enhancing the intensity of fluorescence. As the crystallinity increases, the energy band structure of the crystal may change, thereby changing the peak wavelength of fluorescence.

[0086] By monitoring the crystallization process by real-time detection of the fluorescent signal emitted by the perovskite membrane by the detection component 20, dynamic crystallization process information can be provided, including the growth rate, crystallization quality and uniformity of the crystal, that is, the above-mentioned processing information. By monitoring the changes in the fluorescent signal during the crystallization process, the crystallinity, grain size and uniformity of the perovskite membrane can be analyzed in real time. Parameters such as the duration, intensity, and peak wavelength of the fluorescent signal can reflect the crystallization state of the perovskite membrane. And through the relationship with process parameters (such as temperature, solvent evaporation rate, etc.), the preparation process of the perovskite membrane can be further optimized to improve the crystallization quality.

[0087] Alternatively, the processor 30 may be a spectrum analyzer.

[0088] The outgoing light path of the light source 21 of the above technical solution is substantially perpendicular to the first surface 110, so that the energy of the light is relatively concentrated, the penetration depth and the absorption process are relatively uniform, and the uniform and deep excitation helps to form a larger and more stable excitation volume inside the film to be processed 100, which can increase the duration of the fluorescence peak. In this way, the receiving element 22 can obtain stable and reliable fluorescence for a longer time, so as to more accurately reflect the relevant state data of the film to be processed 100 during the processing process, thereby effectively improving the detection effect during the battery processing process.

[0089] In some embodiments, the receiving member 22 is configured to receive the emitted fluorescent light substantially perpendicular to the first surface 110 .

[0090] For example, in general, the fluorescence characteristics of materials such as perovskite during the crystallization process conform to the Lambertian distribution, that is, the radiation intensity of the fluorescence within a unit solid angle is proportional to the cosine value of the exit angle, so the exit light intensity in the direction perpendicular to the first surface 110 will also be relatively large.

[0091] Therefore, the receiving element 22 is configured to receive the emitted fluorescence substantially perpendicular to the first surface 110, so that the collected fluorescence is more concentrated, stable, and decays more slowly. If the receiving angle of the receiving element 22 deviates from the direction perpendicular to the first surface 110, the fluorescence may be dispersed due to factors such as light scattering, refraction, or reflection, resulting in a shorter duration and lower intensity of the received signal.

[0092] The position and angle of the receiving element 22 may be pre-designed and adjusted so that the receiving element 22 can receive the emitted fluorescence that is substantially perpendicular to the first surface 110 .

[0093] As an example, the receiving member 22 can be mounted on an adjustable bracket or supporting structure so that the position and angle of the receiving member 22 can be adjusted according to the size, shape and configuration of the film 100 to be processed and the light source 21, so that the receiving member 22 can adapt to different types of film 100 to be processed and different light source 21 conditions, thereby further improving the detection accuracy.

[0094] The above technical solution can further improve the intensity and reliability of the fluorescence received by the receiving element 22, thereby further improving the detection effect during the battery processing.

[0095] In some embodiments, the detection component 20 further includes a base 23 , the base 23 is connected to the box 10 , and the light source 21 and the receiving element 22 are both connected to the base 23 .

[0096] The light source 21 may be detachably connected to the base 23, or may be integrally arranged on the base 23. The light source 21 may be directly connected to the base 23, or may be restricted on the base 23 by other components.

[0097] The receiving member 22 may be detachably connected to the base 23, or may be integrally arranged on the base 23. The receiving member 22 may be directly connected to the base 23, or may be restricted on the base 23 by other components.

[0098] The above technical solution not only improves the stability of the light source 21 and the receiving component 22 by introducing the base 23 and connecting and fixing the light source 21 and the receiving component 22 at the same time, but also integrates the light source 21 and the receiving component 22 into one. The light source 21 and the receiving component 22 can be quickly installed or replaced through the connection points on the base 23, thereby reducing assembly time and maintenance costs.

[0099] In some embodiments, the light source 21 and the receiving element 22 are disposed on the same side of the film 100 to be processed.

[0100] Exemplarily, the light source 21 and the receiving element 22 are both located on one side of the first surface 110 of the film 100 to be processed. The light source 21 emits light to the first surface 110 of the film 100 to be processed to stimulate the first surface 110 side of the film 100 to produce fluorescence, and the receiving element 22 receives the fluorescence emitted from the first surface 110 side.

[0101] In some examples, the battery processing device further includes a carrier, which is disposed in the accommodating cavity 11 and connected to the box body 10, and is used to support the film 100 to be processed. The light source 21 and the receiving element 22 are disposed on the same side of the carrier.

[0102] By arranging the light source 21 and the receiving element 22 on the same side, the light propagation path is shortened and the signal loss is reduced, thereby improving the detection sensitivity and accuracy of the signal. In addition, the light source 21 and the receiving element 22 are arranged on the same side, which makes the assembly and alignment operations easier and reduces the complexity of adjusting the optical elements in different directions.

[0103] In some embodiments, there are multiple detection components 20, and the light sources 21 of the multiple detection components 20 are configured to emit light of different wavelengths.

[0104] In this embodiment, each detection component 20 includes a light source 21 and a receiving component 22. Each detection component 20 emits light of a specific wavelength through its own light source 21 to excite the film 100 to be processed to generate different fluorescence.

[0105] The term "plurality" in the present application refers to two or more than two, for example, two, three, four, five, etc.

[0106] It is understandable that light of different wavelengths has different penetration depths into the film to be processed 100. For example, light of short wavelength (e.g., 320nm and 380nm) is absorbed faster by the material and has a relatively shallow penetration depth, while light of long wavelength (e.g., 500nm and 600nm) interacts weakly with the material and has a relatively greater penetration depth.

[0107] The above technical solution introduces multiple detection components 20, and the light source 21 of each detection component 20 can emit light of different wavelengths, so as to detect relevant status data of different depths of the membrane 100 to be processed, thereby effectively improving the detection accuracy and breadth during the battery processing.

[0108] In some embodiments, the detection component 20 is configured to be movable relative to the box 10 .

[0109] Exemplarily, the detection component 20 may be mounted on an adjustable guide rail, a sliding mechanism or a mechanical arm, so that the detection component 20 can be moved relative to the box 10 .

[0110] The movable configuration of the detection component 20 allows the detection component 20 to flexibly adjust its detection range during the processing. For example, when processing a larger size of the film 100 to be processed, the detection component 20 can be moved along the first surface 110 of the film 100 to be processed to achieve comprehensive detection; while for a small film 100 to be processed, the detection component 20 can be fixed at a specific position for local high-precision detection.

[0111] As an example, the detection component 20 may move linearly along a fixed track or rail.

[0112] As an example, the detection component 20 can also rotate or swing around a fixed axis to change the detection angle or adapt to diaphragms of different shapes. For example, the detection component 20 can be mounted on a rotating arm so that it can detect around a specific area of ​​the diaphragm.

[0113] As an example, a multi-degree-of-freedom robotic arm may also be used to enable the detection component 20 to move flexibly in multiple directions to meet different detection requirements.

[0114] As an example, an operator manually drives the detection component 20 to move.

[0115] As an example, the detection unit may be driven by a stepping motor or a servo motor.

[0116] As an example, a pneumatic cylinder or a hydraulic cylinder may be used to drive the detection component 20 to move.

[0117] The above technical solution can cover the entire detection area of ​​the film 100 to be processed by the mobile configuration of the detection component 20, thereby improving the comprehensiveness of the detection. In addition, for films of different specifications, the detection component 20 can be adapted by adjusting the position without reinstalling or replacing a new detection component 20, thereby improving the versatility and adaptability of the battery processing device. In addition, since the detection component 20 can flexibly adjust the position and angle, the irradiation area of ​​the light source 21 and the fluorescence collection range of the receiving component 22 can be more accurately controlled, which helps to reduce errors and improve detection accuracy.

[0118] In some embodiments, there are multiple detection components 20 , and each of the multiple detection components 20 is configured to be movable relative to the box body 10 .

[0119] Exemplarily, the plurality of detection components 20 may move independently of each other or may move synchronously in a linked manner.

[0120] In some embodiments, the battery processing device further includes a driving component, which is connected to the detection component 20 and is used to drive the detection component 20 to move.

[0121] Exemplarily, the driving component may be, but is not limited to, a stepper motor, a servo motor, a cylinder, a hydraulic cylinder, or a robotic arm.

[0122] The detection component 20 can be detachably connected to the driving component, or can be integrally arranged on the driving component. The receiving component 22 can be directly connected to the driving component, or can be restricted on the driving component through other components.

[0123] The above technical solution can reduce manual intervention in adjusting the position of the detection equipment and improve the degree of automation of the battery processing device by introducing a driving component.

[0124] In some embodiments, the battery processing device further includes a control component, which is connected to the driving component and is used to control the driving component to start and stop.

[0125] For example, the control component may include, but is not limited to, a programmable logic controller, an embedded controller, a computer control system, or a wireless control module.

[0126] The operator can input operating instructions through the control component to control the position adjustment of the detection component 20, which helps to further improve the ease of use of the battery processing device.

[0127] In some embodiments, the box body 10 includes a first wall 12, and a first channel 121 is formed on the first wall 12, and the first channel 121 penetrates the first wall 12 along the thickness direction Z of the first wall 12. The detection component 20 is disposed outside the box body 10 and is configured to be arranged opposite to the first channel 121 along the thickness direction Z. The battery processing device also includes a light-transmitting component 40, which is sealed and connected to the first wall 12 and covers the first channel 121.

[0128] The detection component 20 is configured to be able to be set relative to the first channel 121 along the thickness direction Z. As an example, the detection component 20 may be fixedly set on the box body 10 and opposite to the first channel 121 along the thickness direction Z; as another example, the detection component 20 may be movably set, and the detection component 20 can reach a position opposite to the first channel 121 along the thickness direction Z by its own movement.

[0129] Exemplarily, the light emitted by the light source 21 passes through the transparent component 40 and the first channel 121 to irradiate the first surface 110 of the film 100 to be processed, and the fluorescence generated by the film 100 to be processed passes through the first channel 121 and the transparent component 40 to be received by the receiving element 22.

[0130] The light-transmitting component 40 is sealed to the first wall 12 to reduce external interference to the environment inside the box 10, such as dust, humidity or air flow, so that the light-transmitting component 40 can maintain smooth transmission of optical signals while maintaining the sealing of the box 10.

[0131] As an example, the light-transmitting component 40 may be made of a material with high light transmittance, such as quartz glass, sapphire glass, polycarbonate, etc., to maximize the transmission of optical signals while reducing light scattering and reflection losses.

[0132] As an example, the light-transmitting component 40 and the first wall 12 may be connected by threaded fixing, adhesive sealing or O-ring sealing.

[0133] Optionally, the projection shape of the first channel 121 along the thickness direction Z may be, but is not limited to, a circle, a rectangle, a triangle, an ellipse, or the like.

[0134] The above technical solution can not only reduce the impact of the detection component 20 on the internal processing environment of the box 10 by arranging the detection component 20 outside the box 10, but also facilitate the installation and maintenance of the detection component 20. In addition, this design makes the detection component 20 relatively independent from the box 10 structure, facilitates modular design, and improves the compatibility and scalability of the equipment.

[0135] In some embodiments, there are multiple first channels 121 , and the multiple first channels 121 are spaced apart along a direction perpendicular to the thickness direction Z.

[0136] For example, the plurality of first channels 121 may be arranged at intervals along the first direction X, or may be arranged at intervals along the second direction Y, or may be arranged in an array with some being arranged at intervals along the first direction X and others being arranged at intervals along the second direction Y. The first direction X, the second direction Y and the thickness direction Z are perpendicular to each other.

[0137] The above technical solution realizes multi-point detection by opening a plurality of first channels 121 at different positions of the box body 10, thereby being able to obtain more comprehensive detection data and improving the stability and accuracy of the detection.

[0138] In some embodiments, there are multiple detection components 20 , and the number of detection components 20 may be the same as or different from the number of first channels 121 .

[0139] As an example, the number of the detection components 20 is two, and the number of the first channels 121 is nine.

[0140] In some embodiments, the number of the light-transmitting component 40 may be one, and the light-transmitting component 40 as a whole covers a plurality of first channels 121 in the thickness direction Z.

[0141] In some embodiments, there are multiple light-transmitting components 40, and the multiple light-transmitting components 40 are arranged one-to-one with the multiple first channels 121. This can improve the material utilization of the light-transmitting components 40, reduce the volume of a single light-transmitting component 40, facilitate installation and removal, and help reduce costs.

[0142] In some embodiments, the light-transmitting component 40 is detachably connected to the first wall 12. For example, a snap-on or screw-in installation can be adopted, so that maintenance personnel can easily remove and replace the light-transmitting component 40, thereby improving the convenience of use of the battery processing device.

[0143] In some embodiments, the battery processing device further includes a first heating component 50, which is used to heat the film to be processed 100. The first heating component 50 is disposed in the accommodating cavity 11 and is located between the first wall 12 and the film to be processed 100. A second channel 51 is provided on the first heating component 50, and the second channel 51 penetrates the first heating component 50 along the thickness direction Z, and the second channel 51 at least partially overlaps with the first channel 121 along the thickness direction Z.

[0144] The main function of the first heating component 50 is to controllably heat the film 100 to be processed to meet specific processing requirements. For example, in the crystallization process of the perovskite film, appropriate heating can accelerate the formation of crystals.

[0145] As an example, the first heating component 50 is connected to the housing 10. The first heating component 50 may be detachably connected to the housing 10, or may be integrally provided on the housing 10. The first heating component 50 may be directly connected to the housing 10, or may be restricted on the housing 10 by other components.

[0146] Optionally, the first heating component 50 may adopt, but is not limited to, resistance heating, infrared heating, hot air circulation or other heating methods.

[0147] The second channel 51 and the first channel 121 may partially overlap along the thickness direction Z, or the second channel 51 and the first channel 121 may overlap along the thickness direction Z.

[0148] Exemplarily, the light emitted by the light source 21 passes through the light-transmitting component 40, the first channel 121 and the second channel 51 successively to irradiate the first surface 110 of the film 100 to be processed, and the fluorescence generated by the film 100 to be processed passes through the second channel 51, the first channel 121 and the light-transmitting component 40 successively to be received by the receiving element 22.

[0149] Optionally, the projection shape of the second channel 51 along the thickness direction Z may be, but is not limited to, a circle, a rectangle, a triangle, an ellipse, or the like.

[0150] As an example, the projection shape of the second channel 51 along the thickness direction Z is the same as the projection shape of the first channel 121 along the thickness direction Z.

[0151] The above technical solution helps to improve the processing quality of the film 100 to be processed by introducing the first heating component 50. In addition, by opening the second channel 51 on the first heating component 50 and aligning it with the first channel 121, the light path can smoothly pass through the heating component, reducing the influence of the heating component on the detection, and improving the accuracy of the detection data.

[0152] In some embodiments, the battery processing device further includes a second heating component 60 , which is disposed on a side of the film 100 to be processed that faces away from the first heating component 50 , and is used to support and heat the film 100 to be processed.

[0153] The second heating component 60 is mainly used to cooperate with the first heating component 50 to controllably heat the film 100 to be processed, so as to improve the uniformity of heating.

[0154] As an example, the second heating component 60 is connected to the housing 10. The second heating component 60 may be detachably connected to the housing 10, or may be integrally provided on the housing 10. The second heating component 60 may be directly connected to the housing 10, or may be restricted on the housing 10 by other components.

[0155] Optionally, the second heating component 60 may adopt, but is not limited to, resistance heating, infrared heating, hot air circulation or other heating methods.

[0156] The second heating component 60 can carry the film 100 to be processed. That is, the second heating component 60 can be used to heat the film 100 to be processed and reused as a carrier to carry the film 100 to be processed.

[0157] The above technical solution further introduces the second heating component 60 to achieve double-sided heating, so that the film 100 to be processed can be heated more evenly, thereby helping to improve processing quality and production efficiency. In addition, the second heating component 60 can also serve as a carrier for the film 100 to be processed, which helps to reduce the overall structural complexity of the battery processing device.

[0158] In some embodiments, the battery processing device further includes a moving mechanism 70, which is disposed on the side of the first wall 12 facing away from the accommodating cavity 11. The moving mechanism 70 includes a connecting member 71 and a first moving member 72, the connecting member 71 is fixed to the first wall 12, and the first moving member 72 is movably connected to the connecting member 71 and configured to be able to move relative to the connecting member 71 along a first direction X. The detection component 20 is movably connected to the first moving member 72 and configured to be able to move relative to the first moving member 72 along a second direction Y, and the first direction X, the second direction Y and the thickness direction Z are perpendicular to each other.

[0159] The connecting member 71 is fixedly mounted on the first wall 12 as a supporting structure of the entire moving mechanism 70. The connecting member 71 can be made of high-strength metal material (such as aluminum alloy, stainless steel) or high-rigidity engineering plastic to improve the reliability of the kicking mechanism as a whole.

[0160] The first moving member 72 is movably connected to the connecting member 71 and can move along the first direction X to adjust the position of the detection component 20. The first moving member 72 can be moved by, but is not limited to, a slide rail, a guide rail, or a ball screw.

[0161] The detection component 20 is movably connected to the connection member 71 and can move along the second direction Y to adjust its position. The movement of the detection component 20 can be but is not limited to using a slide rail, a guide rail or a ball screw.

[0162] The connecting member 71 may be detachably connected to the first wall 12, or may be integrally provided on the first wall 12. The connecting member 71 may be directly connected to the first wall 12, or may be restricted on the first wall 12 by other components.

[0163] The first moving member 72 may be detachably connected to the connecting member 71, or may be integrally provided on the connecting member 71. The first moving member 72 may be directly connected to the connecting member 71, or may be restricted on the connecting member 71 by other components.

[0164] The detection component 20 may be detachably connected to the first moving member 72, or may be integrally provided on the first moving member 72. The detection component 20 may be directly connected to the first moving member 72, or may be restricted on the first moving member 72 by other components.

[0165] The above technical solution realizes the mobile setting of the detection component 20 by introducing the moving mechanism 70, which has a simple structure, is easy to maintain, and helps to reduce costs.

[0166] In some embodiments, the moving mechanism 70 further includes a second moving member 73, which is movably connected to the first moving member 72 and configured to be movable relative to the first moving member 72 along the second direction Y. The detection component 20 is movably connected to the second moving member 73 and configured to be movable relative to the second moving member 73 along the thickness direction Z.

[0167] The second moving member 73 is movably connected to the first moving member 72 and can move along the second direction Y to adjust the position of the detection component 20. The second moving member 73 can be moved by, but is not limited to, a slide rail, a guide rail, or a ball screw.

[0168] The second moving member 73 may be detachably connected to the first moving member 72, or may be integrally provided on the first moving member 72. The second moving member 73 may be directly connected to the first moving member 72, or may be restricted on the first moving member 72 by other components.

[0169] The above technical solution can conveniently realize the movement setting of the detection component 20 in three-dimensional space by further introducing the second movable member 73. At the same time, without changing the detection component 20, the movement of the detection component 20 along the thickness direction Z can be used to adjust the size of the light spot emitted by the light source 21 to the first surface 110, thereby changing the light intensity per unit area to reduce the risk of damaging the membrane 100 to be processed due to excessive light.

[0170] In some embodiments, the moving mechanism 70 further includes a first locking member, which is connected between the connecting member 71 and the first moving member 72 , and is used to lock or unlock the first moving member 72 .

[0171] For example, after the position adjustment of the detection component 20 is completed, the first locking member is first used to lock the first movable member 72 to fix the detection component 20 to maintain the stability and reliability of the subsequent detection process. After the detection is completed, the first movable member 72 is unlocked to realize the movable setting of the detection component 20.

[0172] As an example, the first locking member may be mechanically locked, such as by using a bolt, buckle or ratchet structure, and by tightening or snapping into a fixed point, the first moving member 72 is locked. This method is simple in structure and low in cost.

[0173] As an example, the first locking member may also adopt an electromagnetic locking method, for example, releasing the lock when power is on, and locking the first movable member 72 when power is off, which helps to improve operational efficiency.

[0174] The above technical solution introduces the first locking member to fix the detection component 20 after the detection component 20 is adjusted in position, which can reduce the risk of vibration or shaking of the detection component 20 during the detection process, thereby improving the detection stability.

[0175] In some embodiments, the moving mechanism 70 further includes a second locking member, which is connected between the first moving member 72 and the second moving member 73 , and is used to lock or unlock the second moving member 73 .

[0176] In some embodiments, the moving mechanism 70 further includes a third locking member, which is connected between the second moving member 73 and the detection component 20 , and is used to lock or unlock the detection component 20 .

[0177] It should be noted that the second locking member and the third locking member may have the same structure as the first locking member. The specific structural details of the second locking member and the third locking member can refer to the relevant content of the above-mentioned first locking member, which will not be repeated here.

[0178] In some embodiments, the battery processing device further includes a vacuum pump 80 , which is connected to the receiving chamber 11 and is used to evacuate the receiving chamber 11 .

[0179] For example, during the processing of the battery, some processes (such as drying, coating, plating or gas replacement) need to be carried out in a low-pressure environment to reduce the impact of impurities in the air and improve the processing quality. For example, during the crystallization of the perovskite membrane, the vacuum environment can accelerate the volatilization of the solvent and improve the crystallization efficiency.

[0180] As an example, the vacuum pump 80 may be connected to the accommodating chamber 11 via a pipeline or a vacuum interface, so that a low-pressure environment can be quickly established.

[0181] Optionally, a vacuum valve may be provided between the vacuum pump 80 and the accommodating chamber 11 to control the vacuuming speed and pressure level.

[0182] Optionally, the vacuum pump 80 may be, but is not limited to, a rotary vane vacuum pump 80 , a dry screw vacuum pump 80 , a scroll vacuum pump 80 , a Roots vacuum pump 80 , a molecular pump, an ion pump, or the like.

[0183] If not otherwise specified, all implementations and optional implementations of the present application can be combined with each other to form a new technical solution. All technical features and optional technical features of the present application can be combined with each other to form a new technical solution.

[0184] In order to better understand the battery processing device provided in the embodiment of the present application, based on the same inventive concept, an embodiment of the above-mentioned battery processing device in actual application is provided here for illustration.

[0185] The embodiment of the present application provides a battery processing device, which includes a box 10, a detection component 20, a processor 30, a light-transmitting component 40, a first heating component 50 and a second heating component 60. The box 10 has a housing 11, and the housing 11 is used to accommodate the perovskite membrane. The box 10 includes a first wall 12, and a first channel 121 is opened on the first wall 12. The first channel 121 passes through the first wall 12 along the thickness direction Z of the first wall 12. The detection component 20 is arranged outside the box 10 and is configured to be arranged relative to the first channel 121 along the thickness direction Z. The battery processing device also includes a light-transmitting component 40, which is sealed and connected to the first wall 12 and covers the first channel 121. The number of the first channels 121 is multiple, and the multiple first channels 121 are arranged at intervals in a direction perpendicular to the thickness direction Z. The number of the light-transmitting components 40 is multiple, and the multiple light-transmitting components 40 are arranged one-to-one with the multiple first channels 121.

[0186] The detection component 20 is connected to the housing 10, and is configured to be movable relative to the housing 10. The detection component 20 includes a light source 21 and a receiver 22, which are arranged on the same side of the perovskite membrane. The light source 21 is used to emit light to the first surface 110 of the perovskite membrane to excite the perovskite membrane to generate fluorescence, and the outgoing light path of the light source 21 is substantially perpendicular to the first surface 110. The receiver 22 is used to receive the fluorescence, and the receiver 22 is configured to receive the emitted fluorescence substantially perpendicular to the first surface 110. The processor 30 is connected to the receiver 22, and is used to generate processing information according to the fluorescence received by the receiver 22.

[0187] There are multiple detection components 20, and the light sources 21 of the multiple detection components 20 are configured to emit light with different wavelengths.

[0188] The first heating component 50 is used to heat the perovskite membrane. The first heating component 50 is arranged in the accommodating cavity 11 and is located between the first wall 12 and the perovskite membrane. A second channel 51 is provided on the first heating component 50. The second channel 51 penetrates the first heating component 50 along the thickness direction Z. The second channel 51 at least partially overlaps with the first channel 121 along the thickness direction Z. The second heating component 60 is arranged on the side of the perovskite membrane facing away from the first heating component. The second heating component is used to carry and heat the perovskite membrane.

[0189] The outgoing light path of the light source 21 of the above technical solution is substantially perpendicular to the first surface 110, so that the energy of the light is relatively concentrated, the penetration depth and the absorption process are relatively uniform, and the uniform and deep excitation helps to form a larger and more stable excitation volume inside the perovskite membrane, which can increase the duration of the fluorescence peak. In this way, the receiving element 22 can obtain stable and reliable fluorescence for a longer time, so as to more accurately reflect the relevant state data of the perovskite membrane during the processing process, thereby effectively improving the detection effect during the battery processing process.

[0190] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0191] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
