Description

Technical Field

[0001] The present application belongs to the field of electronic manufacturing technology, and in particular relates to a lighting module and a glue coating detection device. Background Art

[0002] In industrial testing, it is often encountered that UV glue and other types of glue are applied in the same area at the same time. At this time, part of the UV glue will be mixed with other glues. Therefore, in industrial testing, it is required to extract the glue path of the UV glue mixed with other glues.

[0003] Since UV glue itself has fluorescent properties and is a type of adhesive that must be cured by ultraviolet light, the currently commonly used lighting modules can illuminate the area to be inspected with ultraviolet light. However, when a camera or other image sensor is used to photograph the surface of the area to be inspected, the contrast between the image of the UV glue coating and the images of other glues is not high, resulting in poor accuracy in segmenting the UV glue using image processing algorithms, and inability to accurately obtain information on the complete glue path of the UV glue.

[0043] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0044] Reference below Figure 1-Figure 3 The lighting module and the glue coating detection device according to the embodiments of the present application are described.

[0045] Reference Figures 1 to 3 The lighting module 100 includes a barrel 110 , a first light source 120 and a second light source 130 .

[0046] The barrel 110 has a light outlet, and the barrel 110 has a first installation area and a second installation area arranged toward the light outlet. Thus, the arrangement of the first installation area and the second installation area makes the installation and arrangement of the light source more reasonable and compact. This design can effectively utilize the space inside the barrel 110, and improve the energy efficiency and lighting effect of the entire lighting module 100. The arrangement of the light outlet allows the light emitted by the first light source 120 and the second light source 130 to be emitted from the light outlet, and the propagation direction and range of the light can be better controlled. This design can reduce the waste and loss of light and improve lighting efficiency.

[0047] The first light source 120 is installed in the first installation area. The first light source 120 is used to emit ultraviolet light, and the brightness of the first light source 120 is L1. In this way, the UV glue will undergo a curing reaction under the irradiation of ultraviolet light. By using the first light source 120 with a brightness of L1 to emit ultraviolet light, the UV glue can be effectively activated and quickly cured, thereby improving production efficiency. UV glue usually emits bright fluorescence under ultraviolet light, forming a high contrast with the background. This high contrast allows the inspector to clearly see the coating of the glue, including the uniformity of the coating, whether there are bubbles or defects, etc. Ultraviolet light has a certain stimulating effect on the human eye. By accurately controlling the brightness of the light source to L1, it can be ensured that the brightness of the light source meets the detection requirements and does not cause excessive stimulation to the operator's eyes, thereby protecting the operator's health. Using a dedicated ultraviolet light source and accurately controlling its brightness to L1 helps to ensure the stability and reliability of the detection system. This can reduce false detection or missed detection caused by fluctuations or instability of the light source.

[0048] The second light source 130 is installed in the second installation area. The second light source 130 is used to emit other colored light except ultraviolet light and blue light, and the brightness of the second light source 130 is L2, where 1≤L1 / L2≤10. In this way, UV glue will emit bright fluorescence under ultraviolet light, while other glues may not have this characteristic. By emitting other colored light except ultraviolet light and blue light by the second light source 130, other glues can be visually distinguished from UV glue, which is convenient for identifying the mixed area of ​​UV glue and other glues. There is a large color difference between the colored light emitted by the second light source 130 and the ultraviolet light emitted by UV glue, which helps to improve the contrast between the coating of UV glue and other glues, and accurately segment and extract the glue paths of UV glue and other glues. Since the second light source 130 emits colored light except ultraviolet light and blue light, it will not interfere with the activation and detection of UV glue by the ultraviolet light emitted by the first light source 120. At the same time, the first light source 120 will not interfere with the colored light emitted by the second light source 130, thereby ensuring the independence and accuracy of their respective functions.

[0049] By setting the condition 1≤L1 / L2≤10, it is possible to ensure that the brightness between the two light sources reaches a certain balance. Such a brightness balance not only ensures that the UV glue can be fully activated and detected, but also enables other glues to be clearly identified and distinguished under the irradiation of colored light, making it easy to separate and extract the glue paths of UV glue and other glues from the mixed glue path. According to different detection needs and scenarios, the brightness ratio of the first light source 120 and the second light source 130 can be adjusted to meet actual requirements. This flexibility enables the lighting module 100 to adapt to a variety of mixed coating detection scenarios and improve detection efficiency and accuracy.

[0050] According to the lighting module 100 of the present application, the first light source 120 and the second light source 130 are set, and by setting the condition 1≤L1 / L2≤10, it can be ensured that the brightness between the two light sources reaches a certain balance. Such a brightness balance not only ensures that the UV glue can be fully activated and detected, but also enables other glues to be clearly identified and distinguished under the irradiation of colored light, which facilitates the segmentation and extraction of the glue paths of UV glue and other glues from the mixed glue path. According to different detection needs and scenarios, the actual requirements can be met by adjusting the brightness ratio of the first light source 120 and the second light source 130. This flexibility enables the lighting module 100 to adapt to a variety of mixed coating detection scenarios and improve detection efficiency and accuracy.

[0051] Reference Figure 1 and Figure 2 In one embodiment, the first installation area is arranged in a ring shape and extends circumferentially along the cylinder 110. In this way, the first installation area arranged in a ring shape can ensure that the ultraviolet light source is evenly distributed along the circumference of the cylinder 110, thereby providing uniform ultraviolet light illumination. This is very important for application scenarios that require uniform lighting, such as UV glue coating detection, and can ensure that the entire coating area is evenly illuminated, thereby improving the accuracy and consistency of detection. The ring-shaped design can make full use of the space inside the cylinder 110, making the installation and arrangement of the light source more compact and efficient. This design helps to reduce the volume and weight of the lighting module 100, making it more suitable for various application scenarios, especially in environments with limited space. The first installation area arranged in a ring shape helps to improve the stability of the lighting module 100.

[0052] It should be noted that the annular first installation area can be a continuous annular structure or a discontinuous annular structure along the circumference of the cylinder 110. Specifically, the present application does not limit this.

[0053] Reference Figure 1 and Figure 2 In one embodiment, the second mounting area is arranged in a ring shape and extends circumferentially along the barrel 110. In this way, the second mounting area arranged in a ring shape can ensure that other colored light sources are evenly distributed circumferentially along the barrel 110. This means that in the entire coating area, whether it is UV glue or other glue, it will be illuminated by uniform colored light. This helps to improve the accuracy and consistency of detection, especially when different types of glue need to be distinguished. The annular design once again makes full use of the space inside the barrel 110, making the installation and arrangement of the second light source 130 more compact. This not only helps to reduce the overall size of the lighting module 100, but also makes the module lighter and easier to integrate. The second mounting area arranged in a ring shape helps to improve the stability of the lighting module 100.

[0054] It should be noted that the annular second installation area may be a continuous annular structure or a discontinuous annular structure along the circumference of the cylinder 110 . Specifically, the present application does not limit this.

[0055] In addition, in the above embodiment, at least one of the first installation area and the second installation area may be arranged in a ring shape. Of course, in other embodiments, at least one of the first installation area and the second installation area may also be arranged in a strip shape or a square shape, etc. Specifically, this application does not limit this.

[0056] Reference Figure 2 In one embodiment, the first installation area and the second installation area are arranged at intervals in the radial direction of the barrel 110. In this way, by arranging the first installation area and the second installation area at intervals in the radial direction of the barrel 110, it can be ensured that the light emitted by the first light source 120 and the second light source 130 will not interfere with each other. This ensures that the light emitted by each light source can clearly illuminate the glue coating area, thereby improving the accuracy and reliability of glue path detection when UV glue and other glues are mixed and coated. The radial spacing setting allows the first light source 120 and the second light source 130 to be independently controlled and adjusted. The brightness, color temperature and other parameters of each light source can be adjusted individually according to actual needs to meet different lighting needs. This independent control design provides greater flexibility and convenience. When the light source is working, a certain amount of heat will be generated. By arranging the first installation area and the second installation area at intervals in the radial direction, the heat dissipation effect can be optimized. This helps to reduce the risk of performance degradation or damage of the light source due to overheating and improve the service life and stability of the light source. The radial spacing setting also helps to improve the structural stability of the lighting module 100. By properly allocating space and reducing the mutual compression between light sources, the risk of deformation or damage of the module during use can be reduced, ensuring that the module can operate stably for a long time. The radial spacing arrangement makes the assembly and maintenance of the first light source 120 and the second light source 130 easier, thereby reducing maintenance costs and time.

[0057] Reference Figure 1 and Figure 2In one embodiment, the first mounting area and the second mounting area are staggered along the axial direction of the cylinder 110. Thus, by staggering the first mounting area and the second mounting area in the axial direction of the cylinder 110, the spatial overlap between the two can be effectively reduced, thereby saving space inside the cylinder 110. This is particularly important for the lighting module 100 that requires a compact design, especially in application scenarios where space is limited. The axial staggered setting can further reduce the direct interference between the first light source 120 and the second light source 130. Even if the two work at the same time, due to their axial staggered position, the light they emit will not directly intersect, thereby avoiding mutual interference and conflict between the light. The axial staggered design provides greater flexibility for the lighting module 100. The axial staggered setting makes the operation simple when maintaining or replacing the light source, which can greatly reduce the difficulty and cost of maintenance.

[0058] Reference Figure 1 In one embodiment, the first light source 120 includes a plurality of ultraviolet lamp beads 121, and the plurality of ultraviolet lamp beads 121 are arranged at intervals. Thus, by arranging the plurality of ultraviolet lamp beads 121 at intervals, it can be ensured that the UV glue coating area is uniformly illuminated. The ultraviolet light emitted by each lamp bead can complement each other, reduce the blind area of ​​illumination, and thus improve the accuracy and consistency of coating detection. The combined use of a plurality of ultraviolet lamp beads 121 can provide higher brightness, so that the UV glue can be cured more quickly during the coating process. High-brightness ultraviolet light also helps to improve the contrast of the coating, making the boundary between the UV glue and other materials clearer. Due to the use of a plurality of ultraviolet lamp beads 121, when one or more lamp beads fail, the other lamp beads can still continue to work, ensuring the overall reliability of the lighting module 100. The plurality of ultraviolet lamp beads 121 arranged at intervals can dissipate heat more easily. The interval space helps air circulation, reduces the heat accumulation between the lamp beads, and thus reduces the risk of overheating of the ultraviolet lamp beads 121. Effective heat dissipation can extend the service life of the ultraviolet lamp beads 121 and improve the stability of the lighting module 100. The interval arrangement of the plurality of ultraviolet lamp beads 121 makes it more convenient to maintain or replace the lamp beads. The staff can easily access each ultraviolet lamp bead 121 and perform maintenance operations without removing the entire lighting module 100. This design reduces maintenance costs and time.

[0059] Reference Figure 2In one embodiment, the barrel 110 further has a third installation area arranged toward the light outlet, and the lighting module 100 further includes a third light source 140, which is installed in the third installation area, and the third light source 140 is used to emit white light. In this way, the third light source 140 emits white light, which can provide bright lighting for the working area, so that the operator can clearly see the details of the coating path of UV glue and other glues. White light illumination helps to improve the visibility of the working area, making the detection more accurate and efficient. By adding the third light source 140 to emit white light, the lighting module 100 realizes the integration of multiple light sources and can meet different lighting needs at the same time. White light combined with other colored light or ultraviolet light can provide users with more abundant lighting options, so that the lighting module 100 can adapt to more application scenarios. In some application scenarios, using white light as background light can enhance the color contrast of the coating path of UV glue and other glues. White light, as basic lighting, can provide a better background for colored light or ultraviolet light, making the color of the coating path of UV glue and other glues more vivid and prominent. As a part of the lighting module 100 , the third light source 140 can be replaced and maintained independently, similar to other light sources, with simple operation and cost saving.

[0060] It should be noted that the type of the second light source 130, for example, the second light source 130 may include a red light source, an orange light source, a yellow light source, a green light source or a cyan light source. Preferably, in an embodiment of the present application, the second light source 130 includes a red light source, so that the ultraviolet light source is mainly used to detect UV glue, because UV glue emits a specific fluorescence under ultraviolet light. This characteristic enables the ultraviolet light source to accurately identify and locate UV glue. At the same time, the red light source is used to detect other types of glue. Since different glues have different reflection or transmission characteristics under red light, the red light source can help distinguish UV glue from other glues. This dual light source design can ensure accurate and reliable detection of various glues. By combining ultraviolet light sources and red light sources, this lighting module 100 can adapt to different types of glue detection requirements. This design improves the versatility and flexibility of the lighting module 100, making it applicable to more scenarios and applications. By using ultraviolet light sources and red light sources at the same time, the detection results of the two light sources can be comprehensively considered to reduce the possibility of misjudgment and misdetection. This dual verification mechanism improves the accuracy and reliability of detection. The use of dual light source design can identify UV glue and other glues simultaneously during one inspection process without changing the light source or performing multiple inspections. This helps improve inspection efficiency.

[0061] In addition, the first light source 120, the second light source 130 and the third light source 140 may be controlled simultaneously or individually, and the present application does not limit this.

[0062] Reference Figure 1 In one embodiment, the second light source 130 includes a plurality of red lamp beads 131, and the plurality of red lamp beads 131 are arranged at intervals, so that the plurality of red lamp beads 131 are arranged at intervals to ensure that the light is more evenly distributed within the irradiation range. Due to the intervals between the red lamp beads 131, the light emitted by them can complement each other, reduce the blind area of ​​illumination, and thus provide a more uniform illumination effect. This is very important for detecting UV glue and other glues, because uniform illumination can ensure the accuracy and consistency of the detection results. The combined use of multiple red lamp beads 131 can provide higher brightness. Compared with a single lamp bead, multiple lamp beads working at the same time can produce a stronger illumination effect, making the glue coating area brighter. High-brightness red light helps to improve the contrast and clarity of the detection, making the boundary between the glue and other materials clearer. Multiple red lamp beads 131 arranged at intervals help to dissipate heat. The interval space can reduce the heat accumulation between the red lamp beads 131 and reduce the risk of overheating of the red lamp beads 131. Effective heat dissipation can extend the service life of the red lamp beads 131 and reduce the possibility of performance degradation or damage due to overheating. This is essential for maintaining long-term stable operation of the lighting module 100. The multiple red lamp beads 131 arranged at intervals make it more convenient to maintain or replace the lamp beads, and this design reduces the difficulty and cost of maintenance and improves the maintainability of the lighting module 100.

[0063] Reference Figure 1 and Figure 2 In one embodiment, the cylinder body 110 includes a mounting cylinder 111 , a first annular mounting portion 112 and a second annular mounting portion 113 .

[0064] The installation tube 111 is formed with the light outlet, so that the design of the light outlet allows light to be emitted directionally from the inside of the cylinder 110, thereby realizing accurate illumination of a specific area. This directional illumination helps to ensure that the light is directly irradiated on the object to be detected or illuminated, thereby improving the lighting effect and detection accuracy. The existence of the light outlet can control the propagation path of the light, reduce the possibility of light leakage from other positions of the cylinder 110, and maintain the working efficiency and accuracy of the lighting module 100. The design of the light outlet makes the installation and maintenance of the lighting module 100 more convenient.

[0065] It should be noted that the present application does not limit the shape and size of the light outlet. The size and shape of the light outlet can be customized according to the needs of the specific application scenario. For example, for a scene that requires wide illumination, a larger light outlet can be designed; for a scene that requires precise illumination, a smaller light outlet can be designed. This flexibility enables the lighting module 100 to adapt to different application scenarios and needs.

[0066] The outer wall of the first annular mounting portion 112 is connected to the inner wall of the mounting tube 111, and the first annular mounting portion 112 forms the first mounting area, so that this connection method provides structural stability, which is crucial to ensure accurate and reliable lighting effects.

[0067] The outer wall surface of the second annular mounting portion 113 is connected to the inner wall surface of the first annular mounting portion 112, and the second annular mounting portion 113 forms the second mounting area, so that the internal components of the lighting module 100 can be compactly arranged. This compact design helps to reduce the overall volume and occupied space of the module, making the lighting module 100 more lightweight and easy to integrate into various devices or systems. By connecting the second annular mounting portion 113 to the first annular mounting portion 112, the heat dissipation performance of the lighting module 100 can be optimized. The second annular mounting portion 113 can serve as part of the heat dissipation channel to promote the conduction and dissipation of heat inside the module and prevent heat accumulation from causing performance degradation or damage. The design of the second annular mounting portion 113 helps to improve the overall stability of the lighting module 100.

[0068] In addition, by dividing the barrel 110 into three levels, namely, the mounting barrel 111, the first annular mounting portion 112, and the second annular mounting portion 113, the various components of the lighting module 100 can be clearly organized and managed. By dividing the barrel 110 into different parts, the heat distribution and conduction path inside the module can be better controlled.

[0069] It should be noted that, in the above embodiment, the mounting cylinder 111, the first annular mounting portion 112 and the second annular mounting portion 113 can be integrally formed. Of course, in other embodiments, the mounting cylinder 111, the first annular mounting portion 112 and the second annular mounting portion 113 can also be connected in an appropriate manner (such as welding, threaded connection, etc.) to improve the structural strength of the entire module. This design helps to reduce the possibility of deformation or damage of the module during use.

[0070] Reference Figure 1In one embodiment, a first acute angle a is formed between the end face of the first annular mounting portion 112 facing the light outlet and the inner wall surface of the mounting tube 111, so that the existence of the first acute angle a can guide the light to be emitted from the inside of the mounting tube 111 through the light outlet. Due to the existence of the first acute angle a, the light will be subjected to a certain refraction or reflection when passing through the first acute angle a, thereby changing the propagation direction of the light, making it more concentrated or evenly irradiated to the area that needs to be illuminated. The design of the first acute angle a helps to reduce the loss of light during the propagation process inside the mounting tube 111. The design of the first acute angle a can simplify the overall structure of the lighting module 100 and avoid too many optical elements or complex designs. By cleverly utilizing the first acute angle a, effective guidance and diffusion of light can be achieved, thereby reducing dependence on additional optical elements.

[0071] It should be noted that by reasonably designing the size and shape of the first acute angle a, the diffusion angle and irradiation range of the light can be controlled, so that the lighting effect is more uniform, soft and does not produce glare. This helps to improve the comfort and visual effect of the lighting module 100. By optimizing the angle of the first acute angle a, the reflection and scattering of light at the intersection can be reduced, so that more light can be successfully emitted from the light outlet, thereby improving the lighting efficiency. The size of the first acute angle a can be adjusted according to the needs of the specific application scenario.

[0072] Specifically, in an embodiment of the present application, the first acute angle a is θ1, wherein 30°≤θ1≤80°, preferably, θ1=60°.

[0073] In one embodiment, a second acute angle is formed between the end surface of the second annular mounting portion 113 facing the light outlet and the inner wall surface of the mounting tube 111, so that the second acute angle helps to guide the light to be emitted from the inside of the mounting tube 111 through the light outlet. By designing the second acute angle, the propagation direction and focusing effect of the light can be further controlled, so that the light can be irradiated to the target area more concentratedly, and the lighting intensity and uniformity can be improved. The design of the second acute angle helps to reduce the loss of light during the propagation process inside the mounting tube 111. The design of the second acute angle can simplify the overall structure of the lighting module 100 and avoid too many optical elements or complex designs. By cleverly utilizing the second acute angle, effective guidance and diffusion of light can be achieved, thereby reducing dependence on additional optical elements.

[0074] It should be noted that by reasonably designing the size and shape of the second acute angle, the diffusion angle and irradiation range of the light can be controlled, so that the lighting effect is more uniform, soft and does not produce glare. This helps to improve the comfort and visual effect of the lighting module 100. By optimizing the angle of the second acute angle, the reflection and scattering of light at the intersection can be reduced, so that more light can be successfully emitted from the light outlet, and the lighting efficiency is improved. The size of the second acute angle can be adjusted according to the needs of the specific application scenario.

[0075] Specifically, in an embodiment of the present application, the second acute angle is θ2, wherein 30°≤θ2≤80°, preferably, θ2=60°.

[0076] Reference Figure 2 In one embodiment, the barrel 110 further includes a third annular mounting portion 114, the outer wall surface of the third annular mounting portion 114 is connected to the inner wall surface of the second annular mounting portion 113, and the third annular mounting portion 114 forms the third mounting area. In this way, by introducing the third annular mounting portion 114 and forming the third mounting area, the design of the lighting module 100 becomes more modular and expandable. This means that the components in the third mounting area can be easily added, removed or replaced as needed without making large-scale changes to the entire barrel 110. This modular design helps to improve the flexibility and maintainability of the system. The addition of the third annular mounting portion 114 further subdivides the internal space of the barrel 110, which helps to reduce mutual interference and conflict between components and improve the stability and reliability of the lighting module 100.

[0077] In one embodiment, the end surface of the third annular mounting portion 114 facing the light outlet is vertically arranged with the inner wall surface of the mounting tube 111, and the vertical arrangement can ensure that the connection between the third annular mounting portion 114 and the mounting tube 111 is more stable. The vertical surface provides a larger contact area and a stronger supporting force, making the connection between the two more reliable and less prone to loosening or offset. This stability is essential for maintaining the stability and reliability of the lighting module 100 during operation. The vertical arrangement simplifies the manufacturing between the third annular mounting portion 114 and the mounting tube 111, which helps to reduce manufacturing costs and improve production efficiency. The vertical arrangement helps to optimize the heat dissipation performance of the lighting module 100. When the end surface is perpendicular to the inner wall surface, heat can be conducted more directly and efficiently along the connection surface, reducing the accumulation and obstruction of heat at the connection. This helps to accelerate the dissipation of heat, reduce the operating temperature of the module, and improve the service life and stability. The lines of the vertically arranged end surface and the inner wall surface are simple and clear, which conforms to modern aesthetic standards and improves the aesthetics of the lighting module 100.

[0078] Reference Figure 3In a second aspect, the present application further provides a glue coating detection device 1000, and the glue coating detection device 1000 includes the lighting module 100 as described above.

[0079] According to the glue coating detection device 1000 of the present application, the first light source 120 and the second light source 130 are set, and by setting the condition 1≤L1 / L2≤10, it can be ensured that the brightness between the two light sources reaches a certain balance. Such a brightness balance not only ensures that the UV glue can be fully activated and detected, but also enables other glues to be clearly identified and distinguished under the irradiation of colored light, which facilitates the segmentation and extraction of the glue paths of UV glue and other glues from the mixed glue path. According to different detection needs and scenarios, the actual requirements can be met by adjusting the brightness ratio of the first light source 120 and the second light source 130. This flexibility enables the lighting module 100 to adapt to a variety of mixed coating detection scenarios and improve detection efficiency and accuracy.

[0080] Reference Figure 3 In one embodiment, the glue coating detection device 1000 further includes an image acquisition component 200, and the image acquisition component 200 is connected to the lighting module 100, so that the lighting module 100 provides uniform and sufficient lighting for the image acquisition component 200, ensuring that the image acquisition component 200 can clearly capture the details and features of the glue coating. This helps to reduce interference factors such as shadows and reflections in the image, thereby improving the precision and accuracy of the detection. The combination of the lighting module 100 and the image acquisition component 200 makes the glue coating detection process more automated. The image acquisition component 200 can automatically capture the image of the glue coating, and analyze and process it through software algorithms, thereby realizing fast and accurate detection of the glue coating quality. The glue coating detection device 1000 can realize fast image acquisition and processing, greatly improving the detection efficiency. At the same time, automated detection also reduces the interference of human factors and improves the consistency and stability of detection. This design can also reduce misjudgments and missed detections during the detection process, further reducing the detection cost.

[0081] It should be noted that there are many types of image acquisition components 200 , for example, the image acquisition component 200 may include a camera. Specifically, in the embodiment of the present application, the image acquisition component 200 includes a camera 210 and a lens 220 connected to the camera 210 .

[0082] The following uses the first light source 120 emitting ultraviolet light and the second light source 130 emitting red light as an example to illustrate the working principle of the glue coating detection device 1000 of the present application:

[0083] The glue coating detection device 1000 mainly utilizes the spectral characteristics of the glue itself. UV glue itself is a transparent liquid, which will solidify under the irradiation of ultraviolet light and produce a fluorescent reaction. Therefore, when irradiated with ultraviolet light, the UV light will excite blue light to enter the image acquisition component 200. When irradiating UV glue with red light, because UV glue is transparent, it will not reflect red light back to the image acquisition component 200. The color of other glues after curing is white, gray or grayish white, so other glues will reflect the red light irradiated on the surface, so that the image finally taken in the image acquisition component 200 is actually a reflection of the red light of other glues. The higher the reflectivity of other glues to red light, the greater the grayscale value of the final image. At the same time, because UV glue hardly reflects red light, the grayscale value of the RGB channel where the UV glue and other glues are mixed on the image is obviously different from other areas on the image. The larger the difference value is, the higher the contrast between the UV glue and other glue mixed areas is, so that the respective glue paths of the UV glue and other glue in the mixed area can be extracted and separated.

[0084] It should be noted that when the image acquisition component 200 shoots the mixed glue under the action of the lighting module 100, glues of different materials can be easily distinguished by color, but there will also be a problem of local high reflection (red) in the UV glue (blue area). Since it can be determined that the area is UV glue, the red information in the image of the area can be directly filtered, that is, after the UV glue area is preliminarily determined by the algorithm, the red channel information of the area is cleared to eliminate the impact of high reflection.
