[0002] This application is a divisional application of Chinese patent application No. 202211229012.2, filed on October 9, 2022, entitled “Device for measuring the mixing ratio of colloidal raw materials”. Technical Field

[0003] The present application relates to the field of colloid technology, and in particular to a device for measuring the mixing ratio of colloid raw materials. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0005] Multiple components on a battery can be bonded or sealed using colloids. The colloid is made by mixing multiple raw materials, and the mixing ratio of the raw materials has a crucial impact on the performance of the colloid. However, the measurement accuracy of the mixing ratio of the colloid raw materials in related technologies is low. Summary of the Invention

[0006] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present application is to provide a device for measuring the mixing ratio of colloid raw materials to solve the problem of low measurement accuracy of the mixing ratio of colloid raw materials.

[0007] An embodiment of the present application provides a device for measuring the mixing ratio of colloid raw materials, which includes a mixing unit, a photographing device, and a processor. The mixing unit includes a container and a stirring unit arranged in the container. The container is used to hold the raw materials that make up the colloid. The raw materials that make up the colloid have different colors. The stirring unit can move relative to the container so that all the raw materials are mixed into a mixed glue to be tested. The photographing device is used to obtain an image of the mixed glue to be tested. The processor is electrically connected to the photographing device. The processor determines the mixing ratio of each raw material based on the grayscale value of the pixel point in the image obtained by the photographing device. In addition, the device also includes a light source, and the light emitted by the light source can be projected onto the mixed glue to be tested.

[0008] The device for measuring the mixing ratio of colloidal raw materials in the technical scheme of the embodiment of the application obtains the colored mixed colloidal material to be measured, and determines the mixing ratio of the raw materials by obtaining the image of the mixed colloidal material to be measured. It can be seen that the measuring device is non-contact with the raw materials. Thus, even if the measuring device is operated for a period of time, it will not be abraded due to contact with the raw materials, thereby ensuring that the accuracy of measuring the mixing ratio of colloidal raw materials is high. In addition, the light emitted by the light source can be used to assist in illuminating the mixed colloidal material to be measured. Thus, the image captured by the camera device is clearer, the shooting effect is good, and the measurement accuracy of the mixing ratio of colloidal raw materials is improved.

[0009] In some embodiments, the camera device is configured to be rotatable about a horizontal axis. In this way, the camera device can rotate about the horizontal axis, greatly improving the camera range of the camera device. Thus, the position of the mixed colloidal material to be measured can be flexible, and the camera device can obtain images of the mixed colloidal material to be measured located at different positions by rotating, thereby having a wide range of application.

[0010] In some embodiments, the container is a colloidal storage pipe, at least a portion of the colloidal storage pipe is a transparent pipe body, and the transparent pipe body is located in the camera range of the camera device. By setting the container as a colloidal storage pipe and at least a portion of the colloidal storage pipe as a transparent pipe body, the camera device can directly aim at the transparent pipe body for shooting, without the need to move the mixed colloidal material to be measured to other components for shooting, thereby obtaining the image of the mixed colloidal material to be measured in the colloidal storage pipe.

[0011] In some embodiments, the colloidal storage pipe extends along a vertical direction. Thus, the mixed colloidal material to be measured can flow naturally to the bottom end of the colloidal storage pipe, thereby facilitating the camera device to obtain the mixed colloidal material to be measured.

[0012] In some embodiments, a test support plate for placing the mixed colloidal material to be measured is further included, and the test support plate is located below the camera device and in the camera range of the camera device. In this way, compared with shooting the mixed colloidal material to be measured in the colloidal storage pipe, there is less interference.

[0013] In some embodiments, the light source includes a ring-shaped lamp, the middle part of the ring-shaped lamp has a through hole, the orthographic projection of the surface of the ring-shaped lamp facing away from the horizontal plane is at least located in the through hole, and the mixed colloidal material to be measured is opposite to the through hole of the ring-shaped lamp. The projection direction of the light emitted by the ring-shaped lamp can be the same as the shooting direction of the camera device, and the ring-shaped lamp can also illuminate the surroundings of the camera device, thereby further facilitating the improvement of the shooting clarity and the shooting effect.

[0014] In some embodiments, the camera device is located in the through hole, and the ring-shaped lamp surrounds the outside of the camera device. By installing the camera device in the through hole, the utilization rate of the middle space of the ring-shaped lamp is greatly improved, and the possibility of the ring-shaped lamp interfering with the image of the mixed colloidal material to be measured is reduced.

[0015] In some embodiments, the photographing device is located upstream of the ring-shaped lamp along the projection direction of the light rays of the ring-shaped lamp, so as to avoid the photographing device from casting a shadow on the position of the mixed glue to be measured due to the imaging end facing away from the ring-shaped lamp, and to make the obtained image clearer.

[0016] In some embodiments, the light source further comprises a strip-shaped lamp, the strip-shaped lamp is opposite to the through hole, and a projection of the strip-shaped lamp on a side of the ring-shaped lamp facing away from the horizontal plane is staggered with a projection of the photographing device on the side of the ring-shaped lamp facing away from the horizontal plane. In this way, the light rays emitted by the strip-shaped lamp can irradiate the mixed glue to be measured without hindering the photographing device from obtaining the image of the mixed glue to be measured, the defect that the middle part of the ring-shaped lamp cannot illuminate the mixed glue to be measured is compensated, and the brightness of the light source is enhanced.

[0017] In some embodiments, a plurality of strip-shaped lamps are provided, and the plurality of strip-shaped lamps are arranged at intervals along a first direction, the first direction being parallel to the radial direction of the through hole. In this way, the number of strip-shaped lamps is increased, and the light intensity of the light source is thus increased, so that the obtained image is clearer, and the measurement accuracy of the mixing ratio is thus improved.

[0018] In some embodiments, a plurality of photographing devices are provided, and the plurality of photographing devices are arranged at intervals along a second direction, the second direction being parallel to the radial direction of the through hole and perpendicular to the first direction. In this embodiment, a plurality of photographing devices are provided, and the plurality of photographing devices are standby, so as to avoid the measurement device from being unable to operate due to the failure of one of the photographing devices.

[0019] In some embodiments, the photographing device is located upstream of the strip-shaped lamp along the projection direction of the light rays of the strip-shaped lamp, so as to avoid the photographing device from casting a shadow on the position of the mixed glue to be measured due to the imaging end facing away from the strip-shaped lamp, and to make the obtained image clearer.

[0020] In some embodiments, a light shield cover is further provided, the light shield cover has an opening, at least part of the light source is installed in the light shield cover, and the light rays emitted by the light source can be projected onto the mixed glue to be measured through the opening, the light shield cover can reflect part of the light rays emitted by the light source inside the light shield cover, so as to make the light rays concentrate on the mixed glue to be measured and be projected from the opening.

[0021] In some embodiments, a support is further provided, the light shield cover and at least part of the light source are installed on the support. The support provides a position for the installation of the light shield cover and at least part of the light source.

[0022] In some embodiments, the support comprises a vertical rod and a horizontal rod, the vertical rod is vertically erected along a vertical direction, one end of the horizontal rod is connected to the vertical rod, and the other end of the horizontal rod is a free end, and the light shield cover and at least part of the light source are installed on the horizontal rod. By providing that the support comprises the vertical rod and the horizontal rod, the light shield cover and at least part of the light source are installed at a certain height.

[0023] In some embodiments, the light shield is provided with a first opening and a second opening, the center line of the first opening and the center line of the second opening are arranged in line, and the crossbar passes through the first opening and the second opening in sequence. In this way, the connection between the light shield and the crossbar is reliable, and the crossbar of the support is at least partially located in the light shield. The portion of the crossbar passing through the light shield can provide a mounting position for the portion of the component mounted in the light shield.

[0024] In some embodiments, an opening is arranged at the bottom of the light shield, the ring-shaped lamp is connected to the bottom of the light shield and surrounds the opening, the shooting device and the strip-shaped lamp are arranged in the light shield, and the strip-shaped lamp is mounted on the crossbar.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components.

[0051] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0052] In related art, multiple battery components can be bonded or sealed using colloids. This means that colloids are often used during battery production. However, the inventors have noted that using colloids for bonding can lead to slow curing, resulting in low battery assembly efficiency, or low bonding strength, resulting in loose connections.

[0053] After careful research, the inventors discovered that the main cause of these issues is that the colloid is made from a mixture of multiple raw materials. Improper mixing of these raw materials can easily lead to slow or even no curing, or low bond strength. To address this issue, the inventors discovered that the mixing ratio of the raw materials can be measured during the colloid production process. Based on the measured results, the mixing ratio can be adjusted promptly to prevent imbalance in the mixing ratio of the produced colloid.

[0054] Figure 1 Schematic diagram of a device 100 for preparing colloid in the related art. Figure 1 As shown, a device 100 for producing a colloid in the related art includes two glue barrels 110, two feeding pipes 120, a dispensing valve 130, and a mixing pipe 140. The two glue barrels 110 are respectively used to contain different raw materials for the colloid. One end of each of the two feeding pipes 120 is connected to a different glue barrel 110, and the other end of each of the two feeding pipes 120 is connected to the inlet of the dispensing valve 130. The outlet of the dispensing valve 130 is connected to the mixing pipe 140. In this way, the feeding pipes 120 convey the raw materials to the dispensing valve 130, which in turn conveys the raw materials to the mixing pipe 140 for mixing to produce the colloid.

[0055] And, each feeding pipe 120 is provided with a flow meter 121 and a metering controller 122. The flow meter 121 can measure the flow of the raw material delivered to the glue outlet valve 130 within a certain period of time. Based on the flow values obtained by the two flow meters 121, the mixing ratio of the various raw materials can be calculated and analyzed. When the mixing ratio is out of balance, the amount of raw material delivered to the glue outlet valve 130 can be adjusted by adjusting the metering controller 122 to adjust the mixing ratio of the raw materials until the mixing ratio meets the preset range. The flow meter 121 can be a gear flow meter 121 or a screw flow meter 121. That is, the above-mentioned glue preparation device 100 uses a gear flow meter 121 or a screw flow meter 121 to detect the flow value of each raw material to calculate the mixing ratio of the raw materials.

[0056] However, the inventors found that using such a way to measure the mixing ratio of the raw materials of the glue, since the glue flows through the gear flow meter 121 or the screw flow meter 121, the flow meter 121 will wear out after the glue preparation device 100 has been running for a period of time, and the flow value detected by the flow meter 121 will not be accurate, which will further cause the measurement of the mixing ratio of the raw materials to be inaccurate.

[0057] In addition, the above-mentioned glue preparation device 100 is not suitable for preparing large or small amounts of glue. In other words, when the amount of glue required for the production of the battery is too large or too small, the mixing ratio of the raw materials of the glue prepared by the above-mentioned glue preparation device 100 often has the problem of imbalance. The reason mainly lies in that the working principle of the gear flow meter 121 and the screw flow meter 121 is similar. Taking the gear flow meter 121 as an example, the principle of detecting the flow value is that the raw material flowing through the gear flow meter 121 will drive the gear to rotate, and each tooth of the gear will generate a pulse, and a pulse signal proportional to the flow will be obtained, and then the flow value will be calculated. When the amount of glue prepared is too small, the raw material flowing through the flow meter 121 is correspondingly less, and the raw material is difficult to drive the gear to rotate, which will cause inaccurate measurement. When the amount of glue prepared is too large, the raw material flowing through the flow meter 121 is correspondingly more, and the rotation speed of the gear is difficult to match, which will cause inaccurate measurement.

[0058] To solve the above-mentioned problems, the inventors thought of changing the device for measuring the mixing ratio of the raw materials of the glue from measuring by contacting the raw materials to measuring without contacting the raw materials. In this way, the wear of the device caused by contact is avoided, and the problem of inaccurate measurement is solved, and the device can be used to prepare large or small amounts of glue. Under the inspiration of this technical concept, the inventors finally designed a device for measuring the mixing ratio of the raw materials of the glue. The measuring device mixes the colored raw materials constituting the glue into colored mixed glue to be measured by a glue mixing member, and uses a shooting device to obtain an image of the mixed glue to be measured. A processor determines the mixing ratio of the raw materials of the glue according to the gray value of the pixel points in the image.

[0059] The device for measuring the mixing ratio of colloid raw materials disclosed in the embodiments of the present application can be applied in the production process of batteries, and specifically can be used in the process of preparing colloid on batteries.

[0060] The battery can be used as a power source for mobile terminals, tablets, laptops, electric vehicles, electric toys, electric tools and other electric devices, and can provide power for the above-mentioned electric devices. The battery can specifically include a box body and a battery cell 200 (refer to Figure 2 As shown in FIG, a battery cell 200 is the smallest unit of a battery and can realize the conversion between electrical energy and chemical energy.

[0061] The battery cell 200 should be understood in a broad sense, that is, the battery cell 200 can be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 200 can be cylindrical, rectangular, or in other shapes. Figure 2 This is an exploded schematic diagram of a battery cell 200 having a colloid prepared by the device 300 for measuring the mixing ratio of colloid raw materials according to an embodiment of the present application. Figure 2 Taking a rectangular battery cell 200 as an example, the battery cell 200 may specifically include an end cap assembly 210, a housing 220, a cell assembly 230, and other functional components. The housing 220 is provided with an inlet. The end cap assembly 210 covers the inlet of the housing 220 and, together with the housing 220, forms a storage space isolated from the external environment. This storage space can accommodate the cell assembly 230, electrolyte, and other components. The end cap assembly 210 and the housing 220 can be bonded together using a colloid, which also acts as a seal, isolating the space enclosed by the end cap assembly 210 and the housing 220 from the exterior of the battery cell 200.

[0062] Figure 3 for Figure 2 A cross-sectional view of the end cap assembly 210 is shown in FIG. Figure 3As shown, in some embodiments, the end cover assembly 210 of the battery cell 200 can include an end cover 211 and a rupture disc 212, the end cover 211 is provided with an exhaust hole 2110, the rupture disc 212 is located above the exhaust hole 2110 and covers the exhaust hole 2110, the rupture disc 212 is configured to crack to open the exhaust hole 2110 when the internal pressure of the battery cell 200 reaches a preset threshold, so that the gas inside the battery cell 200 can be discharged to the outside, to ensure that the battery cell 200 has higher safety. Moreover, the battery also includes a sealing member 213, the sealing member 213 has two opposite surfaces, the two surfaces are respectively bonded to the top surface of the end cover 211 and the surface of the rupture disc 212 facing the inside of the battery cell 200 by the adhesive, so that the rupture disc 212 and the end cover 211 have higher sealing performance. According to the foregoing description, it can be known that the end cover assembly 210 of the battery and the housing 220, the sealing member 213 and the rupture disc 212, and the sealing member 213 and the end cover 211 can be bonded by the adhesive. Therefore, it can be understood that the adhesive is used to complete the assembly, sealing and other processes when producing the battery. In order to make the curing speed of the adhesive fast and the bonding strength high, the device provided in the embodiment can be used to measure the mixing ratio of the adhesive raw materials when preparing the adhesive, so as to avoid the mixing ratio of the adhesive raw materials being out of adjustment.

[0063] Figure 4 A schematic view of a device 300 for measuring the mixing ratio of adhesive raw materials according to some embodiments of the present application. Referring to Figure 4 The device 300 for measuring the mixing ratio of adhesive raw materials according to some embodiments of the present application includes an adhesive mixing member, a shooting device 320 and a processor 330. The adhesive mixing member includes a container 310 and a stirring part 340 arranged in the container 310, the container 310 is used to contain raw materials for forming adhesive, the raw materials for forming adhesive are different in color, and the stirring part 340 can move relative to the container 310 to mix the raw materials into a mixed adhesive 400 to be measured. The shooting device 320 is used to obtain an image of the mixed adhesive 400 to be measured. The processor 330 is electrically connected with the shooting device 320, and the processor 330 determines the mixing ratio of each raw material according to the gray value of the pixel points in the image obtained by the shooting device 320.

[0064] The container 310 can be a box, which can receive the raw materials delivered by the feeding pipe 120 of the measuring device 300, or the top of the box can also have an opening, and the staff can pour the raw materials for forming the glue into the box through the opening. The raw materials for forming the glue include multiple types, and the components of all the raw materials for forming the glue and the corresponding colors are known. Specifically, the multiple raw materials for forming the glue can at least include A glue and B glue. The A glue can be any one of bisphenol A type epoxy resin, linear phenolic epoxy resin, aliphatic glycidyl ether epoxy resin, etc., and the B glue can be any one of alicyclic amine curing agent, polyether amine curing agent, aliphatic amine curing agent, aromatic amine curing agent, etc.

[0065] For example, the raw materials for forming the glue can be A glue and B glue, and the colors of the A glue and the B glue are different. For another example, the raw materials for forming the glue can be more than three types, i.e., in addition to the A glue and the B glue, the raw materials for forming the glue can also include C glue, etc., and at least part of the raw materials have different colors, i.e., part of the raw materials have different colors, part of the raw materials have the same color, or the colors of the more than three types of raw materials can all be different.

[0066] The color of at least one of the raw materials for forming the glue can be a color, and the obtained to-be-tested mixed glue 400 can also have a color. For example, in the embodiment in which the raw materials for forming the glue include two types, the A glue and the B glue can be yellow and blue respectively, and the to-be-tested mixed glue 400 obtained by mixing the two types of raw materials can be green.

[0067] The stirring part 340 can stir the various raw materials into the to-be-tested mixed glue 400 by rotating. In the example, the stirring part 340 can specifically include a stirring shaft 341 and a stirring blade 342, the stirring blade 342 is sleeved on the stirring shaft 341 and rotates with the rotation of the stirring shaft 341. Alternatively, the stirring part 340 can also stir the various raw materials into the to-be-tested mixed glue 400 by moving. Compared with the stirring part 340 rotating to stir the raw materials, the stirring effect is better, so that the various raw materials can be more uniformly mixed. Of course, it can be understood that the measuring device 300 can also include a driving member for providing power for the stirring part 340.

[0068] The photographing device 320 is opposite to the to-be-measured mixed glue 400, so that the image photographed by the photographing device 320 contains the to-be-measured mixed glue 400. Here, the photographing device 320 obtaining the image of the to-be-measured mixed glue 400 should be understood in a broad sense, that is, the photographing device 320 can directly photograph the to-be-measured mixed glue 400 in the container 310 to obtain the image of the to-be-measured mixed glue 400, or can photograph the to-be-measured mixed glue 400 on other components to obtain the image of the to-be-measured mixed glue 400. The photographing device 320 can be a CCD camera or a CMOS camera. The photographing device 320 is not limited to a separate camera, but can also be a camera in a surveillance camera or a camera in a mobile terminal, which is not limited in the embodiment.

[0069] A pixel point is the smallest image unit, and an image can include a plurality of pixel points. The color of each pixel point is composed of three primary colors of red, green and blue, and the color value of the color of each pixel point is composed of three channels of red, green and blue, that is, RGB (red, green and blue). It can be understood that the color of each pixel point in the image corresponds to an RGB value.

[0070] The processor 330 determines the mixing ratio of each raw material according to the gray value of the pixel point in the image obtained by the photographing device 320. Specifically, the processor 330 decomposes the image photographed by the photographing device 320 to obtain three channel images of R channel image, G channel image and B channel image, selects at least one channel image as a target channel image, and determines the mixing ratio of each raw material from the preset mapping relationship between the corresponding channel gray value and the mixing ratio according to the gray value of the pixel point in the target channel image.

[0071] The measuring device 300 can further include a light source. The light emitted by the light source can be projected onto the to-be-measured mixed glue 400. When the photographing device 320 is a camera, the light source can be a flash on the camera. Alternatively, the light source can be independent of the camera, for example, the light source can be a laser light source or a light-emitting diode (LED).

[0072] The measuring device 300 for measuring the mixing ratio of the colloidal raw material provided in the embodiment can obtain the colored to-be-measured mixed glue 400, and determine the mixing ratio of the raw material by obtaining the image of the to-be-measured mixed glue 400. It can be seen that the measuring device 300 is non-contact with the raw material, so that the measuring device 300 will not be worn out due to contact with the raw material even after a period of operation, thereby ensuring high accuracy of measuring the mixing ratio of the colloidal raw material. Since the light emitted by the light source can be used to assist in illuminating the to-be-measured mixed glue 400, the image photographed by the photographing device 320 is clearer, thereby improving the photographing effect and further improving the measurement accuracy of the mixing ratio of the colloidal raw material.

[0073] Furthermore, compared to using a gear flowmeter 121 or a screw flowmeter 121 to detect the flow rate of the raw materials, the measuring device 300 of this embodiment is non-contact with the raw materials. Its measurement principle is independent of the raw material flow rate. Therefore, even if the amount of mixed raw materials is small, the mixing ratio can still be determined based on the grayscale values ​​of the pixels in the image of the mixed rubber 400 to be measured. This makes the measuring device 300 applicable when preparing large or small amounts of rubber.

[0074] It should also be noted that because the raw materials that make up the colloid have color, the colloid produced can also have color after the colloid raw material mixing ratio is adjusted to a preset range using the measuring device 300. This makes it easy to detect whether adhesively connected components (such as the end cap assembly 210 and the seal 213) are coated with colloid during the battery production process.

[0075] According to some embodiments of the present application, the camera 320 is configured to rotate about a horizontal axis. For example, the measuring device 300 may further include a pan-tilt assembly, on which the camera 320 is mounted, and which drives the camera 320 to rotate about the horizontal axis. For example, in an embodiment in which the container 310 is a box with an open top, the pan-tilt assembly may be mounted on a wall, and the camera end of the camera 320 mounted on the pan-tilt assembly may be aligned with the open top of the box to capture the mixed adhesive 400 to be tested contained within the box.

[0076] This design allows the camera 320 to rotate about a horizontal axis, significantly extending its imaging range. This allows for greater flexibility in the positioning of the test adhesive mixture 400. The camera 320 can rotate to capture images of the test adhesive mixture 400 at various locations, broadening its application range. For example, when using the camera 320 to capture images of the test adhesive mixture 400, the camera 320 can be suspended at a certain height. In this case, the camera 320 can rotate to capture images horizontally or downward.

[0077] Alternatively, when the position of the mixed adhesive 400 to be tested is fixed, such a design can reduce the limitation of the installation position of the photographing device 320, and the installation position of the photographing device 320 is more flexible.

[0078] Please refer to Figure 4 As shown, the container 310 may be a glue storage tube, at least a portion of which is a transparent tube body, and the transparent tube body is located within the imaging range of the imaging device 320 .

[0079] In the example, the measuring device 300 can include the glue bucket 110, the glue outlet valve 130, and the glue feeding pipe 120. The glue storage pipe can be in communication with the outlet of the glue outlet valve 130, and the inlet of the glue outlet valve 130 can be in communication with the glue bucket 110 through the glue feeding pipe 120. The glue bucket 110 is used to store raw materials for forming glue. In this way, the raw materials in the glue bucket 110 can be delivered to the glue storage pipe through the glue feeding pipe 120 and the glue outlet valve 130.

[0080] In the example, the entire glue storage pipe can be a transparent pipe body. In the example, the entire glue storage pipe can be made of glass or transparent plastic. When the glue storage pipe is made of transparent plastic, the material of the glue storage pipe can be polycarbonate (PC), acrylic, or polyethylene terephthalate (PET).

[0081] Alternatively, only part of the glue storage pipe can be a transparent pipe body. In one possibility, the glue storage pipe can be composed of multiple pipe bodies, at least one of which is a transparent pipe body located within the camera range of the shooting device 320, and the remaining pipe bodies are non-transparent pipe bodies. Alternatively, in another possibility, the glue storage pipe can be a one-piece, and the glue storage pipe is made of transparent material. Part of the glue storage pipe is covered with an opaque light-shielding film. The part not covered with the light-shielding film can be formed as a transparent pipe body. Compared with the entire glue storage pipe being a transparent pipe body, when only part of the glue storage pipe is a transparent pipe body, the images of the A glue and the B glue captured by the shooting device 320 can be as few as possible, so as to reduce the interference of the images of the A glue and the B glue on the image of the measured mixed glue 400, and to improve the measurement accuracy of the mixing ratio of the glue raw materials.

[0082] By setting the container 310 as the glue storage pipe, and at least part of the glue storage pipe as a transparent pipe body, the shooting device 320 can directly capture the transparent pipe body to obtain the image of the measured mixed glue 400 in the glue storage pipe. In this way, the shooting device 320 can capture the image of the measured mixed glue 400 by capturing the container 310, without the need to move the measured mixed glue 400 to other components for capturing, and the operation is simple.

[0083] Please continue to refer to Figure 4 As shown, the glue storage pipe can extend in the vertical direction. In Figure 4 In the example, the shooting device 320 can be adjusted to be aligned with the glue storage pipe in the horizontal direction to obtain the image of the measured mixed glue 400. When only part of the glue storage pipe is a transparent pipe body, the transparent pipe body can be located at the bottom end of the glue storage pipe.

[0084] By setting the glue storage pipe to extend in the vertical direction, the measured mixed glue 400 formed by mixing can flow naturally to the bottom end of the glue storage pipe, thereby facilitating the shooting device 320 to obtain the measured mixed glue 400.

[0085] According to the foregoing description, the photographing device 320 can also photograph the mixed glue 400 on other components. Figure 5 A schematic diagram of the device 300 for measuring the mixing ratio of glue raw materials according to another embodiment of the present application is applied to the scenario of measuring the mixed glue 400 on the test board 390, Figure 6 For Figure 5 A schematic diagram of the test board 390 coated with the mixed glue 400 is shown. Referring to Figure 5 And Figure 6 As shown in the figure, the other component can be, for example, the test board 390. That is, the measuring device 300 can also include the test board 390, which can be used to place the mixed glue 400 to be measured, and the test board 390 is located below the photographing device 320 and within the photographing range of the photographing device 320.

[0086] In this way, after the mixed glue 400 to be measured is prepared by mixing the glue components, the mixed glue 400 to be measured can be coated on the test board 390, and the test board 390 coated with the mixed glue 400 to be measured is placed below the photographing device 320. At this time, the photographing device 320 can be adjusted to rotate so that the photographing end is aligned downward to the test board 390 to photograph the mixed glue 400 to be measured on the test board 390.

[0087] In this way, after the mixed glue 400 to be measured is prepared by mixing the glue components, the mixed glue 400 to be measured can be coated on the test board 390, and the test board 390 coated with the mixed glue 400 to be measured is placed below the photographing device 320. At this time, the photographing device 320 can be adjusted to rotate so that the photographing end is aligned downward to the test board 390 to photograph the mixed glue 400 to be measured on the test board 390.

[0088] When the photographing device 320 directly photographs the container 310, the image of the container 310 and the image of the raw materials that have not been mixed can also be included in the photographed image, which can easily interfere with the image of the mixed glue 400 to be measured. By such an arrangement, the embodiment reduces the factors affecting the image of the mixed glue 400 to be measured, so as to improve the accuracy of measuring the mixing ratio of glue raw materials.

[0089] In this way, after the mixed glue 400 to be measured is prepared by mixing the glue components, the mixed glue 400 to be measured can be coated on the test board 390, and the test board 390 coated with the mixed glue 400 to be measured is placed below the photographing device 320. At this time, the photographing device 320 can be adjusted to rotate so that the photographing end is aligned downward to the test board 390 to photograph the mixed glue 400 to be measured on the test board 390. Figure 5 As shown in the figure, the light source 360 can specifically include a ring-shaped lamp 361, the middle part of the ring-shaped lamp 361 has a through hole, the photographing range of the photographing device 320 is at least located within the through hole in the orthographic projection of the side of the ring-shaped lamp 361 facing away from the horizontal plane, and the mixed glue 400 to be measured is opposite to the through hole of the ring-shaped lamp 361.

[0090] That is, the horizontal projection of the ring-shaped light 361 surrounds the horizontal projection of the photographing device 320, and the photographing range of the photographing device 320 covers the through hole directly opposite the mixed glue 400 to be tested, so as to ensure that the photographing device 320 can photograph the mixed glue 400 to be tested directly opposite the through hole. Figure 7 A schematic diagram of the ring-shaped light 361 in some embodiments of the present application is shown. Referring to FIG. 3B, the ring-shaped light 361 can specifically include a plurality of groups of light-emitting units 3610, which can be uniformly distributed around the center line of the through hole. Figure 7 As shown, the ring-shaped light 361 can specifically include a plurality of groups of light-emitting units 3610, which can be uniformly distributed around the center line of the through hole.

[0091] In addition, the ring-shaped light 361 can be in the shape of a truncated cone, and the cross-sectional area of the truncated cone-shaped ring-shaped light 361 along the radial direction of the through hole gradually decreases from one end close to the mixed glue 400 to be tested to one end away from the mixed glue 400 to be tested. In this way, the ring-shaped light 361 can to some extent play a role in concentrating the emitted light, so that the light is projected as close to the mixed glue 400 to be tested as possible, which is conducive to improving the shooting effect.

[0092] It should be pointed out that when the photographing device 320 can rotate around the horizontal axis, the ring-shaped light 361 can be configured to rotate around the horizontal axis synchronously with the photographing device 320. In this way, the photographing device 320 can obtain images of the mixed glue 400 to be tested at different positions by rotating, and the ring-shaped light 361 can change positions synchronously to illuminate the mixed glue 400 to be tested in time. Specifically, when the photographing device 320 is rotated to shoot the mixed glue 400 to be tested in the horizontal direction, the light emitted by the ring-shaped light 361 can also be projected on the mixed glue 400 to be tested in the horizontal direction. As shown in FIG. 3B, Figure 5 As shown in FIG. 3B, when the photographing device 320 is rotated to shoot the mixed glue 400 to be tested downward, the light emitted by the ring-shaped light 361 can also be projected downward on the mixed glue 400 to be tested.

[0093] By arranging the ring-shaped light 361 around the photographing device 320, on the one hand, the projection direction of the light emitted by the ring-shaped light 361 can be the same as the shooting direction of the photographing device 320, and the ring-shaped light 361 can also illuminate the surrounding of the photographing device 320, which is further conducive to improving the clarity of shooting and improving the shooting effect, and on the other hand, by arranging the ring-shaped light 361, the through hole can avoid the photographing device 320, so as to uniformly illuminate the mixed glue 400 to be tested without hindering the photographing device 320 to obtain images of the mixed glue 400 to be tested.

[0094] In one example, the camera 320 can be located within the through-hole, with the ring light 361 surrounding the outside of the camera 320. In other words, if the camera 320 is placed within the through-hole, the camera end of the camera 320 can extend to one side of the ring light 361. This way, the ring light 361 is outside the camera's range, preventing it from interfering with the image of the test adhesive mixture 400.

[0095] By installing the camera device 320 in the through hole, the utilization rate of the middle space of the ring light 361 is greatly improved, and the possibility of the ring light 361 interfering with the image of the mixed glue 400 to be tested is reduced.

[0096] In another example, the camera 320 can be located upstream of the ring light 361 in the direction of light projection from the ring light 361. In other words, the ring light 361 is located between the camera end of the camera 320 and the rubber mixture 400 to be tested. In this example, for the camera 320 shooting downward, the centerline of the through hole of the ring light 361 extends vertically, and the camera 320 can be located above the ring light 361.

[0097] Compared with the embodiment in which the photographing device 320 is arranged on the side of the ring light 361 facing the mixed glue 400 to be tested, the present embodiment is designed such that the photographing device 320 is located upstream of the ring light 361 along the projection direction of the light of the ring light 361, so as to avoid the photographing device 320 casting a shadow at the position where the mixed glue 400 to be tested is located due to the camera end facing away from the ring light 361, thereby making the captured image clearer.

[0098] Figure 8 Schematic diagram of the structure of the device 300 for measuring the mixing ratio of colloid raw materials in another embodiment of the present application at a second viewing angle, Figure 9 for Figure 8 A three-dimensional schematic diagram of part of the structure of the measuring device 300 is shown Figure 1 , Figure 10 for Figure 8 A three-dimensional schematic diagram of part of the structure of the measuring device 300 is shown Figure 2 Please refer to Figure 5 、 Figure 8 、 Figure 9 and Figure 10 As shown, in addition to the ring light 361, the light source 360 ​​can also specifically include a strip light 362, and the strip light 362 is opposite to the through hole, and the positive projection of the strip light 362 on the side of the ring light 361 facing away from the mixed glue 400 to be tested is staggered with the positive projection of the shooting device 320 on the side of the ring light 361 facing away from the mixed glue 400 to be tested.

[0099] Similarly to the ring-shaped lamp 361, the light emitted by the strip-shaped lamp 362 can also be projected onto the mixed glue 400 to be tested. The strip-shaped lamp 362 can be located on one side of the ring-shaped lamp 361 or on the other side of the ring-shaped lamp 361, as long as the strip-shaped lamp 362 does not block the camera range of the photographing device 320 and can assist in illuminating the mixed glue 400 to be tested.

[0100] It should be noted that when the photographing device 320 can rotate around the horizontal axis, similarly to the ring-shaped lamp 361, the strip-shaped lamp 362 can also be configured to rotate synchronously with the photographing device 320. In this way, the photographing device 320 can obtain images of the mixed glue 400 to be tested at different positions by rotating, and the strip-shaped lamp 362 can also change positions synchronously to illuminate the mixed glue 400 to be tested in time.

[0101] By arranging the strip-shaped lamp 362, the light source 360 is composed of the ring-shaped lamp 361 and the strip-shaped lamp 362, which enhances the brightness of the light source 360. Moreover, by designing the strip-shaped lamp 362 to face the through hole and be staggered with the photographing device 320, the light emitted by the strip-shaped lamp 362 can be irradiated on the mixed glue 400 to be tested without hindering the photographing device 320 from obtaining images of the mixed glue 400 to be tested, which makes up for the defect that the middle part of the ring-shaped lamp 361 cannot illuminate the mixed glue 400 to be tested. In this way, the mixed glue 400 to be tested can be illuminated around and aimed at, which is conducive to further improving the clarity of the photographing and achieving better photographing effect, and the measurement of the raw material mixing ratio based on the photographed images is more accurate.

[0102] Please continue to refer to Figure 5 and Figure 8 When the light source 360 includes the strip-shaped lamp 362, the strip-shaped lamp 362 is provided in plurality, and the plurality of strip-shaped lamps 362 are arranged at intervals along a first direction (indicated by the X direction in the figure). Figure 5 The first direction is parallel to the radial direction of the through hole. In this way, the number of strip-shaped lamps 362 is increased, which is conducive to improving the illumination intensity of the light source 360 and making the photographed images clearer, thereby improving the measurement accuracy of the mixing ratio.

[0103] Please continue to refer to Figure 5 and Figure 8 On the basis that the strip-shaped lamp 362 is provided in plurality and the plurality of strip-shaped lamps 362 are arranged at intervals along the first direction, the photographing device 320 can be provided in plurality, and the plurality of photographing devices 320 are arranged at intervals along a second direction (indicated by the Y direction in the figure). Figure 5 The second direction is parallel to the radial direction of the through hole and perpendicular to the first direction. It should be noted that in the figure, the thickness direction of the test plate 390 is parallel to the Z direction, and the X direction and the Y direction are perpendicular to the Z direction. Figure 5 two by two.

[0104] Since the first direction is perpendicular to the second direction, the plurality of photographing devices 320 and the plurality of strip-shaped lamps 362 are staggered, the photographing device 320 can normally photograph the mixed glue 400, and the light emitted by each strip-shaped lamp 362 can be projected onto the mixed glue 400, so as to improve the photographing effect of the photographing device 320.

[0105] Of course, in other feasible embodiments, the plurality of strip-shaped lamps 362 and the plurality of photographing devices 320 can be arranged on the same surface, the plurality of strip-shaped lamps 362 and the plurality of photographing devices 320 are uniformly distributed around the center line of the through hole, and each photographing device 320 can be arranged between two adjacent strip-shaped lamps 362.

[0106] In the embodiment, the plurality of photographing devices 320 are arranged, so that the plurality of photographing devices 320 are standby, and the failure of one photographing device 320 does not affect the operation of the measuring device 300. In the embodiment in which the measuring device 300 includes the plurality of photographing devices 320, the plurality of photographing devices 320 obtain a plurality of images, and the measuring device 300 can determine the mixing ratio of the raw materials of the mixed glue 400 according to the average value of the gray values of the pixels in the plurality of images. Alternatively, the measuring device 300 can determine the mixing ratio of each raw material according to the gray value of each pixel in each image, so that a plurality of mixing ratios are obtained. By comparing the plurality of mixing ratio values, it can be verified whether the measurement result is accurate, so as to improve the accuracy of the measurement.

[0107] In the embodiment in which the light source 360 includes the ring-shaped lamp 361 and the strip-shaped lamp 362, along the projection direction of the light of the strip-shaped lamp 362, the photographing device 320 is located upstream of the strip-shaped lamp 362. Thus, as shown in Figure 5 and Figure 8 , the strip-shaped lamp 362 can be located between the ring-shaped lamp 361 and the photographing device 320, or the ring-shaped lamp 361 can be located between the photographing device 320 and the strip-shaped lamp 362. In the example, for the photographing device 320 which photographs downward, the center line of the through hole of the ring-shaped lamp 361 extends in the vertical direction, and the photographing device 320 can be located above the ring-shaped lamp 361 and the strip-shaped lamp 362.

[0108] In this way, along the projection direction of the light of the strip-shaped lamp 362, the photographing device 320 is located upstream of the strip-shaped lamp 362, so as to avoid the photographing device 320 from generating a shadow at the position of the mixed glue 400 due to the camera end facing away from the strip-shaped lamp 362, and to make the photographed image clearer.

[0109] Please continue to refer to Figure 5 and Figure 8As shown, the measuring device 300 can further include a light shield 370 having an opening, and at least part of the light sources 360 are installed in the light shield 370 and the light emitted by the light sources 360 can be projected onto the mixed glue 400 to be measured through the opening.

[0110] Exemplarily, the light shield 370 can specifically have a box shape with an opening on one side. There are two possible cases for the installation of at least part of the light sources 360 in the light shield 370, the first case is that all the light sources 360 (for example, the ring-shaped lamp 361 and the strip-shaped lamp 362) are installed in the light shield 370, and the second case is that part of the light sources 360 are installed in the light shield 370.

[0111] It should be noted that in the embodiment in which the photographing device 320 can rotate around the horizontal axis, since the ring-shaped lamp 361 and the strip-shaped lamp 362 are configured to be able to rotate synchronously with the photographing device 320, the light shield 370 is also configured to be able to rotate synchronously with the photographing device 320, so that the light of the light sources 360 located inside the light shield 370 can always be projected onto the mixed glue 400 to be measured from the opening.

[0112] By providing the light shield 370, on the one hand, the light shield 370 can prevent the glare from interfering with the workers, and on the other hand, the light shield 370 can reflect part of the light emitted by the light sources 360 located inside the light shield 370, so as to promote the light to be concentrated and projected onto the mixed glue 400 to be measured from the opening.

[0113] The measuring device 300 described above can further include a support 350, and the light shield 370 and at least part of the light sources 360 are installed on the support 350. The support 350 is not limited to a columnar structure, but can also be a block structure, and the present embodiment does not limit this. By providing the support 350, the support 350 provides a mounting position for the light shield 370 and at least part of the light sources 360.

[0114] Exemplarily, as shown in Figure 5 , Figure 8 , Figure 9 and Figure 10 , the support 350 can include a vertical rod 351 and a horizontal rod 352, the vertical rod 351 is erected in the vertical direction, one end of the horizontal rod 352 is connected with the vertical rod 351, and the other end of the horizontal rod 352 is a free end, and the light shield 370 and at least part of the light sources 360 are installed on the horizontal rod 352.

[0115] In the embodiment, the horizontal rod 352 can extend in the horizontal direction, one end of the horizontal rod 352 can be connected with the top end of the vertical rod 351, and the horizontal rod 352 has a certain distance from the horizontal plane. In this way, the light shield 370 and the at least part of the light source 360 installed on the horizontal rod 352 also have a certain distance from the horizontal plane, that is, the light shield 370 and the at least part of the light source 360 can be regarded as being hung at a certain height position. By setting the support 350 including the vertical rod 351 and the horizontal rod 352, the light shield 370 and the at least part of the light source 360 are installed at a certain height position.

[0116] In the embodiment, the horizontal rod 352 is rotatably connected with the vertical rod 351, and the horizontal rod 352 can be configured to rotate around its axis to drive the light shield 370 and the part of the light source 360 installed on the horizontal rod 352 to rotate, thereby enabling the shooting device 320 to rotate. The horizontal rod 352 can move between at least a first position and a second position. When the horizontal rod 352 is at the first position, the shooting device 320 can shoot downward, and when the horizontal rod 352 is at the second position, the shooting device 320 can shoot in the horizontal direction.

[0117] As Figure 5 , Figure 8 , Figure 9 and Figure 10 , the light shield 370 can be provided with a first opening and a second opening, the center lines of the first opening and the second opening are arranged in the same line, and the horizontal rod 352 passes through the first opening and the second opening in sequence. That is, the light shield 370 is arranged on the horizontal rod 352. Of course, in some possible embodiments, the light shield 370 can be connected with the horizontal rod 352 by screwing, bonding or other methods.

[0118] In this way, the connection between the light shield 370 and the horizontal rod 352 is reliable, and the horizontal rod 352 of the support 350 has at least part located in the light shield 370. The part of the horizontal rod 352 arranged in the light shield 370 can provide a mounting position for the parts mounted in the light shield 370, so as to avoid the weight of the light shield 370 being too large.

[0119] For example, reference can be made to Figure 5 and Figure 8As shown, the strip light 362 can be installed within the light shield 370 and specifically on the crossbar 352. The opening of the light shield 370 can be specifically located at the bottom of the light shield 370. The ring light 361 is connected to the bottom of the light shield 370 and surrounds the opening. The camera 320 is installed within the light shield 370. The ring light 361 is located at the opening and does not block the opening. This allows light emitted by the strip light 362 within the light shield 370 to pass through the opening and project onto the mixed rubber 400 to be tested. In this way, the light shield 370 can provide a certain degree of protection for the camera 320.

[0120] The measuring device 300 of this embodiment may further include a fixing plate 380, which is located inside the light shield 370 and connected to the light shield 370, and the photographing device 320 is mounted on the fixing plate 380. Figure 9 As can be seen, the fixing plate 380 can be installed at the end away from the opening, so that the camera ends of the camera device 320 installed on the fixing plate 380 are both facing the ring light 361 and the strip light 362. By arranging the fixing plate 380 within the light shield 370, the fixing plate 380 provides a mounting position for the camera device 320 to be installed within the light shield 370.

[0121] Please combine Figure 5 、 Figure 8 、 Figure 9 and Figure 10 In a specific embodiment, the device 300 for measuring the mixing ratio of colloid raw materials may specifically include a glue mixing unit, a shooting device 320 and a processor 330. The glue mixing unit includes a glue storage tube and a stirring unit 340 disposed in the glue storage tube. The glue storage tube is used to hold the raw materials that make up the colloid. The raw materials that make up the colloid have different colors. The stirring unit 340 can move relative to the container 310 to mix the raw materials into a mixed glue 400 to be tested. The shooting device 320 is used to obtain an image of the mixed glue 400 to be tested. The processor 330 is electrically connected to the shooting device 320. The processor 330 determines the mixing ratio of each raw material based on the grayscale value of the pixel point in the image obtained by the shooting device 320.

[0122] according to Figure 5 、 Figure 9 and Figure 10 In the illustrated example, the measuring device 300 further includes a bracket 350, which comprises a vertically extending upright pole 351 and a horizontally extending horizontal rod 352. One end of the horizontal rod 352 is rotatably connected to the top of the upright pole 351, while the other end of the horizontal rod 352 is free. The measuring device 300 further includes a light shield 370, a ring light 361, and a strip light 362. The light shield 370 is disposed on the horizontal rod 352.

[0123] The crossbar 352 can rotate relative to the vertical bar 351 around the horizontal axis, so that the crossbar 352 can drive the strip light 362 connected thereto, the light shield 370 connected thereto, the ring light 361 connected to the light shield 370, and the camera 320 to rotate around the horizontal axis. Specifically, the crossbar 352 can rotate between at least a first position and a second position. When the crossbar 352 is in the first position, as shown in FIG. Figure 9 As shown, the camera end of the camera device 320 faces downward, and the light emitted by the ring light 361 and the strip light 362 is emitted downward; when the crossbar 352 is in the second position, as shown in FIG. Figure 10 As shown, the camera end of the camera device 320 can be directed toward the horizontal direction, and the light emitted by the ring light 361 and the strip light 362 are both emitted approximately in the horizontal direction.

[0124] In this way, when it is necessary to directly measure the raw material mixing ratio of the mixed glue 400 to be tested in the glue storage tube, Figure 4 and Figure 10 , the crossbar 352 can be rotated to the second position, and the shooting device 320 is aligned with the glue storage tube; when it is necessary to measure the raw material mixing ratio of the mixed glue 400 to be tested on the test pallet 390, combined with Figure 5 and Figure 9 , the crossbar 352 can be rotated to the first position, and the test tray 390 can be located below the shooting device 320.
