Background Art

[0002] Coating refers to the process of applying a polymer paste, molten polymer, or polymer solution to paper, cloth, or plastic film to create a composite material (film). For example, when coating lithium battery pole pieces, the primary goal is to evenly apply a slurry with good stability, viscosity, and fluidity to the positive and negative electrode fluids. Pole piece coating is crucial for the battery's capacity, consistency, and safety.

[0003] The coating process generally includes a coating effect detection step, which is an important part of the coating process. In the related art, the coating effect detection device includes: a main bracket and a roller bracket, a roller, a light source assembly, a camera bracket and a camera assembly assembled on the main bracket. The roller bracket is used to install the roller, the roller is used to transmit the material belt, and the light source assembly is used to illuminate the material belt. Camera assemblies are respectively assembled on both sides of the material belt to detect the effect of the material belt, and the camera assembly is mounted on the camera bracket. Each camera assembly generally includes two cameras, and the two cameras can detect the entire width of the material belt through debugging.

[0004] However, the on-site installation of this coating effect detection device is labor-intensive and requires a large number of on-site installers. Furthermore, the camera components need to be image debugged and calibrated, which is labor-intensive and requires high-level skills from the on-site installers.

[0005] Summary of the Invention

[0006] In view of the above problems, the embodiments of the present application provide a coating detection device and a coating system, which can at least solve the problems in the related art that the on-site installation of the coating effect detection device is heavy, a large number of on-site installation personnel are required, the debugging workload is heavy, and the skill requirements for on-site installation and debugging personnel are high.

[0007] On the one hand, an embodiment of the present application provides a coating detection device, comprising: a main bracket and two groups of detection components assembled on the main bracket, each group of detection components comprising: a macro camera and a roller, the roller being used to transmit the material strip, the two groups of detection components being used to detect the two opposite sides of the material strip, respectively, the macro camera in each group of detection components being arranged corresponding to the roller, and the width of the lens of the macro camera being greater than or equal to the width of the corresponding roller.

[0008] The coating detection device provided in the embodiment of the present application uses a macro camera to detect the material strip of the material to be detected. Since the macro camera needs to be close to the material strip, the macro camera can be directly mounted on the main bracket, which can save the installation of the camera bracket. At the same time, the installation of the light source component can also be saved, thereby reducing the layout of the wiring. In addition, since the detection components are compactly assembled, the space occupied by the coating detection device can also be reduced. The coating detection device includes two groups of detection components, each group of detection components includes a macro camera and a roller. The macro camera is set corresponding to the roller, and the width of the lens of the macro camera is greater than or equal to the width of the corresponding roller. It can be applied to the detection of material strips of various widths, and the adjustment and debugging of the macro camera can be reduced, thereby reducing the workload of on-site installation and the on-site installation personnel. It can also reduce the skill requirements of on-site installation and debugging personnel.

[0009] In one possible embodiment, adjustment mechanisms are provided at each end of the macro camera. These adjustment mechanisms are used to adjust the macro camera to have the same distance, height, and inclination from the corresponding rollers. This ensures that the entire macro camera has an ideal field of view of the material strip.

[0010] In a possible embodiment, the adjustment mechanism includes: a connecting component and a base, the connecting component is connected to the end face of the macro camera, the base is arranged on the main bracket, the connecting component is slidably arranged on the base, and the sliding direction of the connecting component is perpendicular to the axial direction of the roller corresponding to the macro camera, a first scale is provided on one of the base and the connecting component, and a first pointer is provided on the other of the base and the connecting component, the first pointer is arranged corresponding to the first scale, and the first pointer and the first scale are used to indicate the sliding distance of the connecting component on the base.

[0011] According to the first pointer and the first scale, the two ends of the macro camera can be adjusted to the same distance from the roller without any specific skill requirements so that the entire macro camera has the same distance from the roller, thereby ensuring the macro camera's optimal observation field of view of the material strip, which can further reduce the skill requirements for on-site installation personnel.

[0012] In a possible embodiment, the coating detection device also includes: a first bolt, a connecting seat is provided on the base, a first connecting hole is provided on the connecting seat, a second connecting hole is provided on the connecting assembly, a center connecting line between the first connecting hole and the second connecting hole is parallel to the sliding direction of the connecting assembly, and the first bolt connects the first connecting hole and the second connecting hole.

[0013] By turning the first bolt, the connecting assembly can move the macro camera closer to or farther from the roller, thereby easily adjusting the position of the macro camera. In addition, when the first bolt is not turned, the first bolt can also fix the connecting assembly and the base to ensure a fixed position between the connecting assembly and the base.

[0014] In a possible embodiment, a slide rail is provided on one of the base and the connecting assembly, and the extension direction of the slide rail is perpendicular to the axial direction of the roller corresponding to the macro camera. A slideway is provided on the other of the base and the connecting assembly, and the slide rail is arranged in coordination with the slideway.

[0015] The cooperation between the slide rail and the slideway can reduce the sliding friction of the connecting component on the base, preventing the connecting component from getting stuck during sliding. In addition, it can also enable the connecting component to drive the macro camera to move in a specific direction to ensure that the macro camera is adjusted to have the best observation angle for the material strip.

[0016] In a possible embodiment, the connecting assembly includes: a first connecting member and a second connecting member, the end face of the macro camera is rotatably connected to the first connecting member, the first connecting member is connected to the second connecting member, the second connecting member is slidably arranged on the base, a second scale is provided on the end face of the macro camera and one of the first connecting members, a second pointer is provided on the end face of the macro camera and the other of the first connecting members, the second pointer and the second scale are provided correspondingly, and the second pointer and the second scale are used to indicate the rotation angle of the macro camera relative to the first connecting member.

[0017] According to the second pointer and the second scale, the two ends of the macro camera can be adjusted to have the same inclination angle to the roller without any specific skill requirements so that the entire macro camera has the same inclination angle to the roller, thereby ensuring the macro camera's optimal observation field of view of the material strip, which can further reduce the skill requirements for on-site installation personnel.

[0018] In a possible embodiment, the coating detection device further includes: a second bolt, a fixing hole is formed on the first connecting member, and the second bolt passes through the fixing hole and is connected to the macro camera.

[0019] After the inclination angle of the macro camera to the roller is set, the second bolt can be inserted into the fixing hole and connected to the macro camera. The second bolt is tightened to create a sufficiently large friction force between the macro camera and the first connecting member to prevent the macro camera from rotating relative to the first connecting member, thereby fixing the first connecting member and the macro camera.

[0020] In a possible implementation manner, the fixing hole is arc-shaped, and the second bolt is slidably disposed in the fixing hole.

[0021] To adjust the macro camera's tilt angle, slightly loosen the second bolt and rotate the macro camera. The second bolt will slide in the curved fixing hole. Once the macro camera's tilt angle is set, tighten the second bolt to secure it to the first connector. This eliminates the need to remove the second bolt, preventing it from being lost.

[0022] In a possible embodiment, the first connecting member is slidably arranged on the second connecting member, and the sliding direction of the first connecting member on the second connecting member is perpendicular to the base. A third scale is provided on one of the first connecting member and the second connecting member, and a third pointer is provided on the other of the first connecting member and the second connecting member. The third pointer is arranged corresponding to the third scale, and the third pointer and the third scale are used to indicate the vertical movement distance of the macro camera relative to the base.

[0023] According to the third pointer and the third scale, the two ends of the macro camera can be adjusted to the same height of the roller without any specific skill requirements so that the entire macro camera has the same height relative to the roller, thereby ensuring the macro camera's optimal observation field of view of the material strip, which can further reduce the skill requirements for on-site installation personnel.

[0024] In a possible embodiment, the coating detection device also includes: a third bolt, a third connecting hole is provided on the first connecting member, a fourth connecting hole is provided on the second connecting member, a center line connecting the third connecting hole and the fourth connecting hole is perpendicular to the base, and the third bolt connects the third connecting hole and the fourth connecting hole.

[0025] Tightening the third bolt can achieve the adjustment of the macro camera in the height direction driven by the first connecting member. In addition, when the third bolt is not tightened, the third bolt can also fix the first connecting member and the second connecting member to ensure a fixed position between the first connecting member and the second connecting member.

[0026] In a possible embodiment, the main bracket has a first table top and a second table top that are parallel and stacked from bottom to top, the two groups of detection components are respectively arranged on the first table top and the second table top, the rollers in the two groups of detection components are staggered, and the vertical sections of the rollers in the two groups of detection components are on the same plumb plane.

[0027] The staggered placement of the two rollers facilitates the assembly of two macro cameras on opposite sides of the web. The vertical cross-sections of the two rollers lie on the same plumb line, preventing the web from interfering with the position of the macro cameras. This also makes the entire coating inspection device more compact, reducing its space requirements.

[0028] In a possible implementation manner, a relief opening is provided on the second table surface, and the relief opening is used to avoid the material strip.

[0029] In a possible implementation, the coating detection device further includes: an encoder component, wherein the encoder component is disposed on the main support, and the encoder component is used to provide a signal for triggering the macro camera to operate.

[0032] In a possible embodiment, the coating detection device further includes: a fixing foot, wherein the fixing foot is provided at the bottom of the main bracket, and the fixing foot is used to fix the main bracket on the target object.

[0033] When the coating detection device is working, vibration is inevitable. The fixing feet can fix the main bracket on the target object to reduce the shaking of the coating detection device and reduce vibration and abnormal noise.

[0034] On the other hand, an embodiment of the present application provides a coating system, characterized in that it includes: a coating device, an oven device, a material recovery device and the above-mentioned coating detection device, and the coating detection device is located between the coating device and the material recovery device.

[0035] The embodiment of the present application provides a coating system, wherein a coating detection device uses a macro camera to detect the material strip of the material to be detected. Since the macro camera needs to be close to the material strip, the macro camera can be directly mounted on the main bracket, which can save the installation of the camera bracket. At the same time, the installation of the light source component can also be saved, thereby reducing the layout of the wiring. In addition, since the detection component is compactly assembled, the space occupied by the coating detection device can also be reduced. The coating detection device includes two groups of detection components, each group of detection components includes a macro camera and a roller. The macro camera is set corresponding to the roller, and the width of the lens of the macro camera is greater than or equal to the width of the corresponding roller. It can be applied to the detection of material strips of various widths, and the adjustment and debugging of the macro camera can be reduced, thereby reducing the workload of on-site installation and the on-site installation personnel.

[0070] The coating process is a process based on the study of fluid properties, in which one or more layers of liquid are applied to a substrate, usually a flexible film or backing paper. The applied liquid coating is then passed through an oven or cured to form a film layer with special functions. The coating process is used in a variety of industries, such as printing, food packaging, medical treatment, and batteries. The coating detection device provided in the embodiments of this application can be applied to various industries related to the coating industry. The embodiments of this application are described in the context of the battery industry.

[0071] The primary purpose of coating lithium batteries is to evenly apply a slurry with good stability, viscosity, and fluidity to the positive and negative electrode fluids. Pole coating is crucial for the battery's capacity, consistency, and safety. The coating process generally includes a coating effectiveness testing step. As the name suggests, this testing step involves testing the effectiveness of the liquid coating applied to the substrate.

[0072] FIG1 is a schematic structural diagram of a lithium battery coating detection device 1 in a related art. Referring to FIG1 , in the related art, the lithium battery coating detection device 1 includes: a main bracket 2 and a roller bracket 3, a roller 4, a light source assembly 5, a camera bracket 6, and a camera assembly 7 mounted on the main bracket 2. The roller 4 is mounted on the roller bracket 3. The roller 4 is used to transmit the material strip 8 (the material to be inspected). The light source assembly 5 illuminates the material strip 8. Camera assemblies 7 are respectively mounted on both sides of the material strip to detect the effect of the material strip 8 after coating. The camera assembly 7 is mounted on the camera bracket 6. With the development of the battery industry, the battery electrodes are getting wider and wider. Each camera assembly 7 generally includes two or more cameras (the accompanying drawings take the camera assembly 7 including two cameras as an example for explanation). The two cameras detect the entire width of the material strip through debugging.

[0073] Because camera assembly 7 is relatively far from the material strip 8 being inspected, both cameras need to be calibrated and debugged. Figure 2 shows a schematic diagram of the debugging of camera assembly 7 in Figure 1. Referring to Figure 2, during calibration and debugging of camera assembly 7, the fields of view of both cameras need to be adjusted to cover the entire width of material strip 8, and the overlap area of ​​the two cameras' fields of view must not be too large. This requires high skills from the on-site installation and debugging personnel.

[0074] In addition, the above-mentioned lithium battery coating detection device requires the installation of a light source assembly 5 and a camera bracket 6, and also requires the arrangement of wiring of the light source assembly 5 and the camera assembly 7. The on-site installation workload is large and requires many on-site installation personnel.

[0075] In order to solve the above problems, the embodiments of the present application provide a coating detection device and a coating system, wherein the coating detection device applies a macro camera to detect the material strip of the material to be detected. Since the macro camera needs to be close to the material strip, the macro camera can be directly mounted on the main bracket, which can save the installation of the camera bracket. At the same time, the installation of the light source component can also be saved, thereby reducing the wiring layout. The coating detection device provided in the embodiments of the present application includes two groups of detection components, each group of detection components includes a macro camera and a roller. The macro camera is set corresponding to the roller, and the width of the lens of the macro camera is greater than or equal to the width of the corresponding roller. It can simplify the adjustment and debugging of the macro camera, thereby reducing the on-site installation workload and on-site installation personnel, and can reduce the skill requirements for on-site installation and debugging personnel.

[0076] The coating detection device and coating system provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and specific embodiments.

[0077] First, let's briefly explain macro cameras. A macro camera is a type of camera that uses a very small lens to capture small objects, such as bacteria and flowers, by reducing the lens's focal length to a very short distance. "Macro" refers to photography at a very close distance and with a high magnification. According to common industry standards, macro photography is defined as photography with an image ratio greater than 1:1.

[0078] Figure 3 is a structural schematic diagram of a coating detection device 100 provided in an embodiment of the present application, and Figure 4 is a side view of the coating detection device 100 in Figure 3. Referring to Figures 3 and 4, the coating detection device 100 provided in an embodiment of the present application includes: a main bracket 110 and two groups of detection components 120 assembled on the main bracket 110.

[0079] Specifically, each group of detection components 120 includes: a macro camera 121 and a roller 122, the roller 122 is used to transmit the material strip 130 of the material to be detected, and the two groups of detection components 120 are respectively used to detect the two opposite sides of the material strip 130. For example, as shown in Figure 4, the main bracket 110 has two layers, the upper and lower layers, and the two groups of detection components 120 are respectively arranged on the upper and lower layers. The two macro cameras 121 and the two rollers 122 are respectively staggered and oppositely arranged in the upper and lower layers, so that the macro camera 121 located on the lower layer of the main bracket 110 can detect the first side 1301 of the material strip 130, and the macro camera 121 located on the upper layer of the main bracket 110 can detect the second side 1302 of the material strip 130.

[0080] The macro camera 121 in each set of detection components 120 is provided corresponding to the roller 122, and the width of the lens of the macro camera 121 is greater than or equal to the width of the corresponding roller 122. The lens width of the macro camera 121 and the width of the roller 122 are defined in correspondence with the width of the material strip 130. It can be understood that the width direction of the lens of the macro camera 121 refers to the width direction of the conveyed material strip 130, and the width direction of the roller 122 also refers to the width direction of the conveyed material strip 130.

[0081] It can be understood that the coating detection device 100 provided in the embodiment of the present application uses the macro camera 121 to detect the material strip 130 of the material to be detected. Since the macro camera 121 needs to be close to the material strip 130, the macro camera 121 can be directly mounted on the main bracket 110, which can eliminate the need for installing the camera bracket. At the same time, the installation of the light source component can also be eliminated, thereby reducing the layout of the wiring. In addition, since the detection component 120 is compactly assembled, the space occupied by the coating detection device 100 can also be reduced. The coating detection device 100 includes two groups of detection components 120, each group of detection components 120 includes a macro camera 121 and a roller 122. The macro camera 121 is set corresponding to the roller 122, and the width of the lens of the macro camera 121 is greater than or equal to the width of the corresponding roller 122. It can be suitable for the detection of material strips 130 of various widths, and can reduce the adjustment and debugging of the macro camera 121, thereby reducing the on-site installation workload and on-site installation personnel, and can also reduce the skill requirements for on-site installation and debugging personnel.

[0082] Of course, the present application is not limited to this. Figure 5 is a top view of a coating detection device 100 provided in an embodiment of the present application. Referring to Figures 4 and 5, in some embodiments of the present application, adjustment mechanisms 140 may also be provided at both ends of the macro camera 121, that is, adjustment mechanisms 140 are respectively provided at both ends of a macro camera 121. The adjustment mechanisms 140 located at both ends of the macro camera 121 are used to adjust the two ends of the macro camera 121 to have the same distance, the same height and the same inclination angle from the corresponding roller 122.

[0083] When observing the material strip 130, the macro camera 121 needs to be adjusted to an ideal position to ensure that the macro camera 121 has an optimal inspection field of view of the material strip 130. Figure 6 is a schematic diagram of the ideal field of view and non-ideal field of view of the material strip 130 during coating inspection. Referring to Figure 6, the horizontal line 1303 in Figure 6 indicates the ideal field of view of the macro camera 121 with respect to the material strip 130, and the inclined line 1304 indicates the non-ideal field of view of the macro camera 121 with respect to the material strip 130. The macro camera 121 needs to be adjusted to an ideal position so that the macro camera 121 has an ideal field of view of the material strip 130, as indicated by the horizontal line 1303 in Figure 6.

[0084] In the embodiment of the present application, adjustment mechanisms 140 are respectively provided at both ends of the macro camera 121. The two adjustment mechanisms 140 at both ends of the macro camera 121 can adjust both ends of the macro camera 121 to the same distance from the corresponding roller 122, thereby ensuring that the entire macro camera 121 is at the same distance from the corresponding roller 122. The two adjustment mechanisms 140 at both ends of the macro camera 121 can adjust both ends of the macro camera 121 to the same height from the corresponding roller 122, thereby ensuring that the entire macro camera 121 is at the same height from the corresponding roller 122. The two adjustment mechanisms 140 at both ends of the macro camera 121 can adjust both ends of the macro camera 121 to the same inclination angle from the corresponding roller 122, thereby ensuring that the entire macro camera 121 is at the same inclination angle from the corresponding roller 122. Taken together, this ensures that the entire macro camera 121 has an ideal observation field of view of the material strip 130.

[0085] The adjustment mechanism 140 can be electronically adjusted or manually adjusted as described below. Compared with the electronic adjustment method, the manual adjustment method can save the manufacturing cost of the entire coating detection device 100.

[0086] Figure 7 is a structural schematic diagram of the adjustment mechanism 140 provided in an embodiment of the present application. Referring to Figure 7 and in combination with Figure 4, in some embodiments of the present application, the adjustment mechanism 140 may include: a connecting component 141 and a base 142. The connecting component 141 is connected to the end face of the macro camera 121. The connecting component 141 and the base 142 can serve as fixing devices for the macro camera 121.

[0087] Specifically, the base 142 is set on the main bracket 110, and the connecting component 141 is slidably set on the base 142. The sliding direction of the connecting component 141 is perpendicular to the axial direction of the roller 122 corresponding to the macro camera 121, that is, the end of the macro camera 121 can be moved closer to or away from the roller 122 with the help of the sliding of the connecting component 141 on the base 142.

[0088] A first scale 1421 is provided on one of the base 142 and the connecting assembly 141, and a first pointer 14121 is provided on the other of the base 142 and the connecting assembly 141. For example, in the embodiment of the present application, the first pointer 14121 is provided on the connecting assembly 141, and the first scale 1421 is provided on the base 142. The first pointer 14121 and the first scale 1421 are provided in a corresponding manner. It is understood that the first pointer 14121 and the first scale 1421, respectively located on the relatively movable connecting assembly 141 and the base 142, can indicate the sliding distance of the connecting assembly 141 on the base 142. Based on this sliding distance, the adjustment mechanism 140 at each end of the macro camera 121 can adjust both ends of the macro camera 121 to the same distance from the roller 122, ensuring that the entire macro camera 121 is at the same distance from the roller 122, thereby ensuring that the macro camera 121 has an optimal field of view of the material strip 130.

[0089] Continuing to refer to FIG. 7 and FIG. 8 , in some embodiments of the present application, a plurality of words are engraved on the first scale 1421 along the first preset direction.

[0090] For example, referring to FIG8 , the first preset direction is from left to right, and the first scale 1421 is marked with 20, 10, 0, 10, and 20, respectively, from left to right. Scale 0 represents the standard distance between the end of the macro camera 121 and the roller 122 under a certain operating condition. Moving 10 units to the left means the end of the macro camera 121 in FIG7 is ten units away from the roller 122. Moving 10 units to the right means the end of the macro camera 121 in FIG7 is ten units closer to the roller 122, and so on. Based on the first pointer 14121 and the first scale 1421, the ends of the macro camera 121 can be adjusted to the same distance from the roller 122 without requiring any specific skills, so that the entire macro camera 121 is at the same distance from the roller 122. This ensures that the macro camera 121 has an optimal field of view of the material strip 130, further reducing the skill requirements for on-site installation personnel.

[0091] It should be noted that the distance between the macro camera 121 and the roller 122 may not be a specific value and may be set according to specific working conditions.

[0092] 3 and 7 , in some embodiments of the present application, the coating detection device 100 may further include a first bolt 150. A connecting seat 1422 is provided on the base 142, a first connecting hole is provided on the connecting seat 1422, a second connecting hole is provided on the connecting assembly 141, a center connecting line between the first connecting hole and the second connecting hole is parallel to the sliding direction of the connecting assembly 141, and the first bolt 150 connects the first connecting hole and the second connecting hole.

[0093] It is understood that by tightening the first bolt 150, the connecting assembly 141 can drive the macro camera 121 toward or away from the roller 122, thereby easily adjusting the position of the macro camera 121. In addition, when the first bolt 150 is not tightened, the first bolt 150 can also fix the connecting assembly 141 and the base 142 to ensure a fixed position between the connecting assembly 141 and the base 142.

[0094] Continuing with reference to Figures 3 and 7 , in some embodiments of the present application, a slide rail may be provided on one of the base 142 and the connecting assembly 141, with the slide rail extending perpendicularly to the axial direction of the roller 122 corresponding to the macro camera 121. A slideway is provided on the other of the base 142 and the connecting assembly 141, with the slide rail and the slideway being provided in coordination. For example, as shown in Figures 4 and 7 , the slide rail 1423 is provided on the base 142, and the slideway is provided on the connecting assembly 141, and the slide rail 1423 is provided in coordination with the slideway.

[0095] It can be understood that the cooperation between the slide rail 1423 and the slideway can reduce the sliding friction of the connecting component 141 on the base 142, preventing the connecting component 141 from getting stuck during sliding. In addition, it can also enable the connecting component 141 to drive the macro camera 121 to move in a specific direction to ensure that the macro camera 121 is adjusted to have the best observation angle for the material strip 130.

[0096] Continuing with reference to Figures 3 and 7 , in some embodiments of the present application, the connection assembly 141 may include a first connection member 1411 and a second connection member 1412. Specifically, the end surface of the macro camera 121 is rotatably connected to the first connection member 1411. It can be understood that the macro camera 121 can rotate relative to the first connection member 1411 along its own axis. The first connection member 1411 is connected to the second connection member 1412, and the second connection member 1412 is slidably arranged on the base 142.

[0097] A second scale 1211 is provided on one of the end surface of the macro camera 121 and the first connecting member 1411, and a second pointer 14111 is provided on the other. For example, as shown in FIG7 , the second scale 1211 is provided on the end surface of the macro camera 121, and the second pointer 14111 is provided on the first connecting member 1411. The second pointer 14111 is provided corresponding to the second scale 1211. It is understood that the second pointer 14111 and the second scale 1211 on the macro camera 121 and the first connecting member 1411 can indicate the rotation angle of the macro camera 121 relative to the first connecting member 1411.

[0098] Continuing to refer to FIG. 7 and FIG. 9 , in some embodiments of the present application, a plurality of words are engraved on the second scale 1211 along the second preset direction.

[0099] Exemplarily, as shown in reference Figure 9, the second preset direction is from left to right, and the second scale 1211 is engraved with 15°, 10°, 0°, 10°, and 15° from left to right, and the words are arranged in an arc shape, with the 0 scale being the standard inclination angle of the end of the macro camera 121 to the roller 122 under a certain working condition. Taking the rotation direction of the macro camera 121 in Figure 7 as an example, when rotating counterclockwise by 10°, the second pointer 14111 indicates the words 10° to the right of 0°, and when rotating clockwise by 10°, the second pointer 14111 indicates the words 10° to the left of 0°, and so on. According to the second pointer 14111 and the second scale 1211, the two ends of the macro camera 121 can be adjusted to have the same inclination angle to the roller 122 without any specific skill requirements so that the entire macro camera 121 has the same inclination angle to the roller 122, thereby ensuring the best observation field of view of the macro camera 121 to the material strip 130, which can further reduce the skill requirements for on-site installation personnel.

[0100] It should be noted that the inclination angle of the macro camera 121 to the roller 122 may not be a specific value and may be set according to specific working conditions.

[0101] 7 , in some embodiments of the present application, the coating detection device 100 may further include a second bolt 160. A fixing hole 14112 is provided on the first connecting member 1411. The second bolt 160 is passed through the fixing hole 14112 and connected to the macro camera 121 to fix the first connecting member 1411 to the macro camera 121. Specifically, after the inclination angle of the macro camera 121 relative to the roller 122 is set, the second bolt 160 can be inserted into the fixing hole 14112 and connected to the macro camera 121. The second bolt 160 is tightened to create a sufficiently large friction force between the macro camera 121 and the first connecting member 1411 to prevent the macro camera 121 from rotating relative to the first connecting member 1411, thereby fixing the first connecting member 1411 to the macro camera 121.

[0102] In some embodiments of the present application, as shown in FIG7 , the fixing hole 14112 may be arc-shaped, with the arc conforming to the rotation direction of the macro camera 121, and the second bolt 160 slides in the arc-shaped fixing hole 14112. It will be appreciated that when the tilt angle of the macro camera 121 needs to be adjusted, the second bolt 160 can be slightly loosened and then rotated. At this point, the second bolt 160 can slide in the arc-shaped fixing hole 14112. Once the tilt angle of the macro camera 121 is adjusted, the second bolt 160 is tightened to secure the macro camera 121 to the first connecting member 1411. This eliminates the need to remove the second bolt 160, preventing loss of the second bolt 160.

[0103] To adjust the height of the macro camera 121, in some embodiments of the present application, the first connecting member 1411 can be slidably mounted on the second connecting member 1412, with the sliding direction being perpendicular to the base 142. The second connecting member 1412 is mounted on the base 142 and cannot move in the height direction. The first connecting member 1411 can be slidably mounted on the second connecting member 1412 in a direction perpendicular to the base 142, thereby enabling the macro camera 121 to be adjusted in the height direction.

[0104] 7 , a third scale mark 14122 is provided on one of the first connecting member 1411 and the second connecting member 1412, and a third pointer 14113 is provided on the other of the first connecting member 1411 and the second connecting member 1412. For example, as shown in FIG7 , the third pointer 14113 is provided on the first connecting member 1411, and the third scale mark 14122 is provided on the second connecting member 1412. The third pointer 14113 is provided corresponding to the third scale mark 14122. It can be understood that the third pointer 14113 and the third scale 14122 located on the first connecting member 1411 and the second connecting member 1412 that can move relative to each other can indicate the vertical movement distance of the macro camera 121 relative to the base 142. According to the movement distance, the adjustment mechanism 140 located at both ends of the macro camera 121 can adjust the two ends of the macro camera 121 to the same height from the roller 122 so that the entire macro camera 121 has the same height from the roller 122, thereby ensuring the optimal observation angle of the macro camera 121 to the material strip 130.

[0105] Continuing to refer to FIG. 7 and FIG. 10 , in some embodiments of the present application, a plurality of words are engraved on the third scale 14122 along the third preset direction.

[0106] Exemplarily, as shown in reference Figure 10, the third preset direction is from top to bottom, and the third scale 14122 is engraved with 20, 10, 0, 10, and 20 from top to bottom, respectively. The 0 scale is the standard height of the end of the macro camera 121 from the roller 122 under a certain working condition. The third pointer 14113 on the first connecting member 1411 moves upward by 10 units, that is, the macro camera 121 in Figure 7 is raised by 10 units relative to the roller 122; moves downward by 10 units, that is, the end of the macro camera 121 in Figure 7 is lowered by 10 units relative to the roller 122, and so on. According to the third pointer 14113 and the third scale 14122, the two ends of the macro camera 121 can be adjusted to the same height of the roller 122 without any specific skill requirements so that the entire macro camera 121 has the same height relative to the roller 122, thereby ensuring the macro camera 121's optimal observation field of view of the material strip 130, which can further reduce the skill requirements for on-site installation personnel.

[0107] It should be noted that the height of the macro camera 121 relative to the roller 122 may not be a specific value and may be set according to specific working conditions.

[0108] Continuing to refer to Figure 7, in some embodiments of the present application, the coating detection device 100 may further include a third bolt 170, a third connecting hole is provided on the first connecting member 1411, and a fourth connecting hole is provided on the second connecting member 1412. The center line between the third connecting hole and the fourth connecting hole is perpendicular to the base 142, and the third bolt 170 connects the third connecting hole and the fourth connecting hole.

[0109] It is understood that tightening the third bolt 170 allows the first connecting member 1411 to drive the macro camera 121 to adjust in the height direction. In addition, when the third bolt 170 is not tightened, the third bolt 170 can also fix the first connecting member 1411 and the second connecting member 1412 to ensure a fixed position between the first connecting member 1411 and the second connecting member 1412.

[0110] Of course, the present application is not limited to this. Continuing to refer to FIG3 and in combination with FIG4 , in some embodiments of the present application, the main bracket 110 has a first table 181 and a second table 182 that are stacked from top to bottom. The two groups of detection components 120 are respectively arranged on the first table 181 and the second table 182. The rollers 122 in the two groups of detection components 120 are staggered, and the vertical sections of the rollers 122 in the two groups of detection components 120 are on the same plumb plane. The staggered arrangement of the two rollers 122 facilitates the assembly of the two macro cameras 121 on both sides of the corresponding material strip 130. The vertical sections of the two rollers 122 are on the same plumb plane, which can prevent the material strip 130 from interfering with the position of the macro camera 121, and can also make the entire coating detection device 100 more compact, reducing the space occupied by the coating detection device 100.

[0111] 3 , a clearance opening 1811 is provided on the first table 181 , and the material belt 130 can pass through the clearance opening 1811 .

[0112] Continuing to refer to Figure 3, in some embodiments of the present application, the coating detection device 100 may also include an encoder assembly 183, which is assembled on the main bracket 110. The encoder assembly 183 is used to provide a signal to trigger the macro camera 121 to work. Its specific working principle can be referred to the existing technology and will not be repeated here.

[0113] Continuing to refer to Figure 3, in the present application, the coating detection device 100 may also include a roller bracket 1221, the roller bracket 1221 is arranged on the main bracket 110, and the roller 122 is arranged on the roller bracket 1221. The roller bracket 1221 can support and fix the roller 122 to ensure the stability of the roller 122 when working.

[0114] Continuing with reference to FIG. 3 and FIG. 4 , in some embodiments of the present application, the coating detection device 100 may further include a fixing foot 190 disposed at the bottom of the main support 110. The fixing foot 190 is used to fix the main support 110 to a target object (e.g., the ground, an object). When the coating detection device 100 is operating, vibration is inevitable. The fixing foot 190 can fix the main support 110 to the target object, reducing the shaking of the coating detection device 100 and reducing vibration and abnormal noise.

[0115] According to some embodiments of the present application, a coating detection device 100 is provided. The coating detection device 100 includes: a main bracket 110, two detection components 120 (a macro camera 121 and a roller 122), an adjustment mechanism 140 located at both ends of the macro camera 121, an encoder component 183 provided on the main bracket 110, a roller bracket 1221, and a fixed foot 190 located at the bottom of the main bracket 110. Among them, the macro camera 121 is mounted on the main bracket 110, which can eliminate the need for installing a camera bracket. At the same time, the need for installing a light source component can also be eliminated, thereby reducing the layout of the wiring. In addition, since the detection component 120 is compactly assembled, the space occupied by the coating detection device 100 can also be reduced. The coating detection device 100 includes two groups of detection components 120, each group of detection components 120 includes a macro camera 121 and a roller 122. The macro camera 121 is set corresponding to the roller 122, and the width of the lens of the macro camera 121 is greater than or equal to the width of the corresponding roller 122. It can be suitable for the detection of material strips 130 of various widths, and can reduce the adjustment and debugging of the macro camera 121, thereby reducing the on-site installation workload and on-site installation personnel, and can also reduce the skill requirements for on-site installation and debugging personnel.

[0116] An embodiment of the present application also provides a coating system 200. Figure 11 is a schematic diagram of the coating system 200 provided in an embodiment of the present application. Referring to Figure 11, the coating system 200 provided in an embodiment of the present application includes: a coating device 210, an oven device 220, a material recovery device 230 and a coating detection device 100 as shown above, wherein the coating detection device 100 is located between the coating device 210 and the material recovery device 230.

[0117] Specifically, in one embodiment, reference may be made to FIG11 , in which the direction of the arrow indicates the transmission direction of the material strip 130. When the material strip 130 passes through the first coating device 210, the coating device 210 coats the first side 1301 of the material strip 130, and then enters the oven device 220 for drying. The second coating device 210 then coats the second side 1302 of the material strip 130, and then enters the oven device 220 for drying. The material strip 130 is then transmitted to the coating detection device 100 to detect the effect of the coating on the material strip 130, and finally collected by the material recovery device 230.
