Description

Technical Field

[0001] This application claims priority based on Korean Patent Application No. 10-2021-0122600, filed on September 14, 2021, and Korean Patent Application No. 10-2022-0111370, filed on September 2, 2022, the entire contents of which are incorporated herein by reference.

[0002] This invention relates to an automatic detection device for two-component resins, an automatic detection system for two-component resins including the automatic detection device, and an automatic detection method for two-component resins. Background Technology

[0003] Currently commercially available rechargeable batteries include nickel-cadmium (NiCd) batteries, nickel-metal hydride (NiMH) batteries, nickel-zinc (NiZn) batteries, and lithium-ion batteries. Among these, lithium-ion batteries exhibit almost no memory effect compared to nickel-cadmium (NiCd) batteries, and are therefore attracting attention due to their free charge / discharge capacity, extremely low self-discharge rate, and high energy density.

[0004] Typically, such lithium-ion secondary batteries use lithium-based oxides as the positive electrode active material and carbon materials as the negative electrode active material. A lithium-ion secondary battery includes: an electrode assembly containing a positive electrode plate coated with a positive electrode active material and a negative electrode plate coated with a negative electrode active material, with a separator inserted between the positive and negative electrode plates; and a coating material used to seal the electrode assembly and electrolyte together. Depending on the shape of the coating material, lithium-ion secondary batteries can be classified as can-type or pouch-type secondary batteries. Such a single secondary battery can be referred to as a battery cell.

[0005] Recently, rechargeable batteries have been widely used not only in small devices (e.g., portable electronic devices) but also in medium and large devices (e.g., vehicles and power storage devices). When using rechargeable batteries in such medium-sized devices, capacity and output can be increased by using battery modules or battery packs with a large number of battery cells electrically connected to each other.

[0006] In one method of configuring this type of battery module or battery pack, multiple battery cells are fixed inside the battery module using an adhesive material (resin or resin composition). In this case, the adhesive material can be injected into the battery module through injection holes formed on the surface of the battery module.

[0007] Specifically, the adhesive material can be a two-component resin including a main resin, a curing agent, etc., and the two-component resin filling the battery module as described above can appropriately absorb the heat generated inside the battery, thereby preventing drastic temperature changes and allowing heat to dissipate to the outside. For the two-component resin to dissipate heat and cure, the mixing state of the main resin and the curing agent constituting the two-component resin is important.

[0008] Reference Figure 1 and Figure 2 Describes a resin injection apparatus for injecting two-component resin into a battery module. Figure 1 This is a front view of a resin injection device based on related technology. Figure 2 yes Figure 1 An enlarged view of the interior of part A.

[0009] Reference Figure 1 and Figure 2 The resin injection device 10 includes a main resin supplier 11, a curing agent supplier 12, a mixing unit 13, an injector 14, and a pressure sensor 15.

[0010] The main resin supplier 11 supplies main resin to the mixing unit 13, and the curing agent supplier 12 supplies curing agent to the mixing unit 13. The main resin supplier 11 and the curing agent supplier 12 supply main resin and curing agent to the mixing unit 13 through separate valves V1 and V2, respectively.

[0011] The mixing unit 13 includes a mixer that mixes the main resin and curing agent supplied through the main resin supplier 11 and the curing agent supplier 12 to obtain a two-component resin. The injector 14 injects the two-component resin into the battery module.

[0012] Pressure sensor 15 measures the pressure generated in the valve during the supply of the main resin and curing agent. The pressure value measured during the mixing of the main resin and curing agent is used to determine whether the two-component resin is normal or defective. Subsequently, after the two-component resin has cured, the operator can visually inspect the color of the two-component resin to determine whether it is normal or defective.

[0013] The drawback of the aforementioned related technologies is that the problem cannot be quickly addressed when the measured pressure value is inaccurate due to contamination / malfunction of the pressure sensor 15. Furthermore, there is always the possibility that when an operator manually inspects the color of the two-component resin with the naked eye, the operator may misjudge the color based on factors such as prolonged inspection or poorly lit working environments.

[0042] This invention can be embodied in many different forms and implemented in multiple embodiments. Therefore, specific embodiments are illustrated in the accompanying drawings and described in detail herein. However, it should be understood that the invention is not limited to the specific embodiments and includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

[0043] The terminology used herein is for describing particular embodiments only and is not intended to limit the invention. As used herein, singular expressions are intended to include plural forms as well, unless the context clearly specifies otherwise. It should be understood that the terms “comprising” and / or “including”, as used herein, specify the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, but do not exclude the presence or addition of one or more features, integers, steps, operations, elements, components, or combinations thereof. Hereinafter, an automatic detection apparatus for two-component resins according to embodiments of the present invention, an automatic detection system for two-component resins including the automatic detection apparatus, and an automatic detection method for two-component resins will be described with reference to the accompanying drawings.

[0044] Figure 3 This is a perspective view of an automatic two-component resin detection device according to an embodiment of the present invention. Figure 4 This is an internal view of the housing of an automatic two-component resin detection device according to an embodiment of the present invention. Figure 5 This is a bottom view of an automatic two-component resin detection device according to an embodiment of the present invention.

[0045] like Figures 3 to 5 As shown, the automatic two-component resin detection device 100 according to an embodiment of the present invention includes a housing 110, an illumination unit 120, a camera unit 130, and a determiner 140. Optionally, the automatic two-component resin detection device 100 may further include a support member 150.

[0046] The housing 110 blocks external light, allowing the brightness of the light emitted from the lighting unit 120 to remain constant. The housing 110 can have one of various shapes, such as a polyhedral or cylindrical shape. An example of a rectangular parallelepiped shape is illustrated in the accompanying drawings. The lower part of the housing 110 is open, allowing the lighting unit 120 to emit light of a certain brightness towards the battery module B below the housing 110, and allowing the camera unit 130 to capture images of the two-component resin R injected into the battery module B. The two-component resin R is injected into the battery module B via a resin injection device positioned in front of the two-component resin automatic detection device 100. The housing 110 can be supported at a certain angle by the support member 150, depending on the workplace facilities.

[0047] The lighting unit 120 emits light toward the open lower part of the housing 110. When it can emit light of a certain brightness toward the lower part of the housing 110, the installation position of the lighting unit 120 is not limited, but... Figure 4 and Figure 5 As shown, multiple light-emitting diodes (LEDs) are preferably evenly mounted on both sides of the upper surface of the housing 110. The type of lighting unit 120 is not limited, as long as it can emit light, and is not limited to LEDs.

[0048] Camera unit 130 acquires images of the two-component resin R injected into battery module B by photographing the resin. The installation location and number of camera units 130 are not limited, but... Figure 4 and Figure 5 As shown, camera unit 130 can be mounted between illumination units 120. Battery module B is located below the open lower part of housing 110 by being moved via a movable unit (e.g., a conveyor belt) between the resin injection device and the two-component resin automatic detection device 100, which is mounted in front of the two-component resin automatic detection device 100. The image of the resin obtained by camera unit 130 can be transmitted to determinant 140.

[0049] Determiner 140 determines the mixing state of the two-component resin in real time based on the color information of the resin image. For example, the color information can be specified by at least one selected from a group consisting of a Hue / Saturation / Lightness (HSV) model, an RGB model, and an L*a*b* model. The HSV model specifies color information using coordinates of hue, saturation, and lightness (luminance value), and compared to the RGB model described below, it more easily represents gradual changes in color gradient. When using the HSV model, changes in shading and chromaticity can be easily represented by fixing two of the three parameters and changing only one. The RGB model specifies color information using three colors (e.g., red, green, and blue), while the L*a*b* model specifies color information using L* (luminance), a* (how close the color is to red or green), and b* (how close the color is to yellow or blue).

[0050] For example, the automatic detection device for two-component resins of the present invention may further include a database unit for storing color information based on the mixing ratio of the two-component resins. Figure 10 This is a graph showing the color information of the mixing ratio of the two-component resin stored in the database unit according to an embodiment of the present invention.

[0051] Reference Figure 10 The color information can vary depending on the mixing ratio between the main resin and the curing agent, so the mixing ratio between the main resin and the curing agent can be estimated based on the color information of the two-component resin.

[0052] exist Figure 10 In the graph, the x-axis represents the mixing ratio of the main resin and the curing agent, and the y-axis represents the color information. Here, 0% mixing ratio information represents the optimal mixing ratio, -5% mixing ratio information represents 5% less curing agent than the optimal mixing ratio, and 5% mixing ratio information represents 5% more curing agent than the optimal mixing ratio.

[0053] Figure 10 The data shown can be collected through the following process.

[0054] First, a two-component resin is prepared by mixing a main resin and a curing agent in a certain ratio, and then an image of the resin is acquired by a camera unit 130. Furthermore, the color information of the image is digitized using at least one method selected from the group consisting of HSV, RGB, and L*a*b* models, and the color information is stored in a database unit.

[0055] Two-component resins are prepared by varying the mixing ratios, and the above process is repeated for the two-component resins prepared with different mixing ratios. In this case, to increase reliability, a large number of samples can be prepared with a single mixing ratio, and the average or median value of the sample color information can be set as a representative value and stored in a database unit. In this case, the number of samples can be in the range of 2 to 50 or 5 to 50.

[0056] For example, the determiner 140 stores a range (hereinafter referred to as the normal range) of color information extracted from an image of a two-component resin in a normal state, extracts color information from an image of the resin transmitted from the camera unit 130, and determines that the mixing state is normal when the extracted color information falls within the stored normal range. When the extracted color information does not fall within the stored normal range, the mixing state is determined to be poor. The normal range can be determined statistically from a large number of images of defect-free two-component resins. For example, referring to... Figure 10 The data shows that when the color information extracted from the image of the target two-component resin falls within ±5% (68.4 or 64.1) of the color information range, the determiner can determine that the target two-component resin is normal.

[0057] As another example, it can be determined that polyurethane resin is normal when its luminance, based on L* corresponding to the color coordinates, falls within the range of 120 to 150, and is defective when it does not fall within that range.

[0058] Meanwhile, when camera unit 130 is configured as a machine vision camera, determiner 140 can be configured as an image processor, software, etc., implemented in the machine vision camera. The machine vision camera includes a high-performance camera, image processor, software, etc. After acquiring an image, the image processor or software processes and analyzes the image according to the purpose of a specific task and provides judgments for performing that task.

[0059] For example, a two-component resin can be a room-temperature curable resin. A room-temperature curable resin is a composition having a system that exhibits a certain level of adhesive ability through a curing reaction at room temperature, and can be, for example, a two-component resin comprising a main resin and a curing agent. Silicone resins, polyol resins, epoxy resins, or acrylic resins can be used as the main resin. Simultaneously, a known curing agent suitable for the main resin can be used as the curing agent. For example, when the main resin is a silicone resin, a siloxane compound can be used as the curing agent; when the main resin is a polyol resin, an isocyanate compound can be used as the curing agent; when the main resin is an epoxy resin, an amine compound can be used as the curing agent; and when the main resin is an acrylic resin, an isocyanate compound can be used as the curing agent.

[0060] For example, a two-component resin can be a two-component polyurethane composition. When using a two-component polyurethane composition, it can contain the components described below. A main resin containing a polyol or the like and a curing agent containing an isocyanate or the like can react and cure together at room temperature. The curing reaction can be accelerated with the help of a catalyst such as dibutyltin dilaurate (DBTDL). Therefore, a two-component polyurethane composition can include a physical mixture of a main resin component (polyol) and a curing agent component (isocyanate) and / or a reaction product (cured product) of the main resin component and the curing agent component.

[0061] According to the present invention, based on the fact that the color of a two-component resin varies according to the mixing ratio between the main resin component and the curing agent component, an image of the two-component resin can be obtained by a camera unit, color information can be obtained from the image, and a determiner can determine in real time whether the mixing ratio between the main component and the curing agent component and its mixing state are poor, and the two-component resin can be detected before curing, thereby preventing the occurrence of a large number of defects.

[0062] For example, a battery module includes a module housing and individual battery cells. The individual battery cells can be housed within the module housing. One or more individual battery cells can be housed within the module housing, or multiple individual battery cells can be housed within the module housing. There is no particular limitation on the number of individual battery cells housed within the module housing, and it can be adjusted according to the application, etc. The individual battery cells housed within the module housing can be electrically connected to each other.

[0063] The module housing may include at least sidewalls and a lower plate forming an internal space for accommodating individual battery cells. The module housing may further include an upper plate for sealing the internal space. The sidewalls, lower plate, and upper plate may be integrally formed with each other. The shape and size of the module housing are not particularly limited and can be appropriately selected according to the application and the shape and number of battery cells to be accommodated in the internal space.

[0064] Next, we will refer to Figure 6An automatic detection system for two-component resins according to an embodiment of the present invention is described. Figure 6 This is a conceptual diagram illustrating an automatic detection system for two-component resins according to an embodiment of the present invention.

[0065] like Figure 6 As shown, the automatic detection system for two-component resin according to an embodiment of the present invention includes a resin injection device 20, an automatic detection device for two-component resin 100, and a moving unit 12.

[0066] The resin injection device 20 is generally similar to the reference device. Figure 1 and Figure 2 The resin injection device 10 described in the related art is the same. However, in this invention, the determiner 140 of the two-component resin automatic detection device 100 determines the mixing state of the two-component resin in real time based on the color information of the resin image, thus eliminating the need for the pressure sensor 15 in the resin injection device 10 of the related art. This is because the function of the pressure sensor 15 in detecting whether the mixing state is normal or defective during the mixing process is redundant. Therefore, the manufacturing cost of the resin injection device 20 can be reduced.

[0067] An automatic two-component resin inspection device 100 is installed behind the resin injection device 20. The automatic two-component resin inspection device 100 obtains an image of the two-component resin R injected into the battery module B by photographing the resin, and determines in real time whether the two-component resin R injected into the battery module B has defects based on the color information of the resin image. (See above for reference.) Figures 3 to 5 The automatic detection device 100 for two-component resins has been described, so it will not be described again here.

[0068] However, when the resin injection device 20 includes a pressure sensor 15, the determiner 140 of the two-component resin automatic detection device 100 can further determine whether the mixing state during the mixing process is normal or defective based on the pressure value obtained by the pressure sensor 15. The determiner 140 can store the range of pressure values ​​that fall within the normal range determined by a statistical method through repeated experiments. When the obtained pressure value falls within the normal range, the determiner 140 can determine that the mixing state is normal. When the pressure value does not fall within the normal range, the determiner determines that the mixing state is defective.

[0069] When the result of determining whether the mixing state is normal based on the pressure value matches the result of determining whether the mixing state is normal based on the color information of the resin image, the determiner 140 determines that the mixing state is normal.

[0070] When the result of determining whether the mixing state is normal based on the pressure value does not match the result of determining whether the mixing state is normal based on the color information of the resin image, the determiner 140 can determine that at least one of the pressure sensor 15 of the resin injection device 20 and the illumination unit 120 and camera unit 130 of the two-component resin automatic detection device 100 has experienced an abnormality, such as contamination or malfunction, and generate an alarm message. The alarm can be issued using at least one of visual, auditory, and tactile means. The alarm message can be generated using at least one of visual, auditory, and tactile means. The operator who recognizes the alarm message can quickly take necessary measures.

[0071] A moving unit CB is installed between the resin injection device 20 and the two-component resin automatic detection device 100. The moving unit CB can be, for example, a conveyor belt. Alternatively, the moving unit CB can be installed in front of the resin injection device 20 and behind the two-component resin automatic detection system 100 to continuously perform pretreatment for injecting two-component resin and posttreatment for detecting two-component resin. The moving unit CB can periodically stop temporarily according to the shooting time of the camera unit 130 of the two-component resin automatic detection device 100 and move after a certain period of time.

[0072] Next, we will refer to Figure 7 An automatic detection method for two-component resins according to an embodiment of the present invention is described. Figure 7 This is a flowchart of an automatic detection method for two-component resins according to an embodiment of the present invention.

[0073] Reference Figure 7 The automatic detection method for two-component resin according to an embodiment of the present invention includes the following steps: injecting two-component resin (S110), obtaining an image of the resin (S120), and determining whether the mixing state is normal (S130).

[0074] In the step of injecting the two-component resin (S110), the resin injection device 20 injects the two-component resin R, prepared by mixing the main resin and the curing agent, into the gaps (spaces between the cylindrical secondary cells) of the battery module B. The battery module B, with the two-component resin R injected, is moved by the moving unit to be located below the open lower part of the housing 110 of the automatic two-component resin detection device 100.

[0075] In the step of obtaining an image of the resin (S120), the camera unit 130 of the two-component resin automatic detection device 100 obtains an image of the resin by photographing the two-component resin injected into the battery module B.

[0076] In the step of determining whether the mixing state is normal (S130), the determiner 140 of the two-component resin automatic detection device 100 identifies the mixing state of the two-component resin in real time based on the color information (brightness, saturation, RGB values, etc.) of the resin image. The determiner 140 extracts color information from the resin image transmitted by the camera unit 130, and determines that the mixing state is normal when the extracted color information falls within the stored normal range.

[0077] Next, we will refer to Figure 8 An automatic detection method for two-component resins according to another embodiment of the present invention is described. Figure 8 This is a flowchart of an automatic detection method for two-component resins according to another embodiment of the present invention. This embodiment can be applied when the resin injection device 20 includes a pressure sensor 15.

[0078] Reference Figure 8 According to another embodiment of the present invention, the automatic detection method for two-component resin includes the following steps: injecting two-component resin (S210), obtaining a pressure value (S220), obtaining an image of the resin (S230), determining whether the mixing state is normal (S240), and generating an alarm message (S250).

[0079] In the step of injecting two-component resin (S210), the resin injection device 20 injects the two-component resin prepared by mixing the main resin and the curing agent into the gaps (spaces between cylindrical secondary cells) of the battery module B.

[0080] In the step of obtaining the pressure value (S220), the pressure sensor 15 of the resin injection device 20 measures and obtains the pressure value generated in the valve during the supply of the main resin and curing agent. The measured pressure value can be transmitted to the determiner 140. In this case, the resin injection device 20 may include a communication module for transmitting the pressure value.

[0081] In the step of obtaining an image of the resin (S230), the camera unit 130 of the two-component resin automatic detection device 100 obtains an image of the resin by photographing the two-component resin injected into the battery module B.

[0082] In the step of determining whether the mixing state is normal (S240), the determiner 140 of the two-component resin automatic detection device 100 identifies the mixing state of the two-component resin in real time based on the color information (brightness, saturation, RGB values, etc.) of the resin image. The determiner 140 extracts color information from the resin image transmitted by the camera unit 130, and determines that the mixing state is normal when the extracted color information falls within the stored normal range.
