Description

Technical Field

[0001] This invention relates to the field of electronic tag manufacturing technology, and more specifically, to an automated production line for electronic tag manufacturing and processing. Background Technology

[0002] Electronic tags, also known as RFID tags, are a non-contact automatic identification technology. They identify target objects and acquire relevant data through radio frequency signals. They offer advantages such as waterproofing, anti-magnetic properties, high-temperature resistance, long lifespan, long reading distance, data encryption, large storage capacity, and flexible information modification. Combined with internet technology, they have enormous development potential. Their basic working principle is that after the tag enters the reader's magnetic field, it receives the radio frequency signal and transmits product information via induced current or actively sends a signal. The reader reads and decodes the signal before sending it to the information processing center. With the application of automation and the demand for efficient management in shopping malls, electronic tags are becoming increasingly widespread, leading to the development of electronic tag automation. The quality requirements for electronic tag products are also increasing. With technological advancements, electronic tags are now produced on automated production lines. After production, electronic tags need to be tested by supporting testing equipment, and defective products are reworked.

[0003] In existing electronic tag stamping processes, excessive burrs and dimensional deviations occur due to mold wear and force fluctuations. Traditional imaging equipment typically uses a single camera at a fixed angle under a fixed light source, lacking effective auxiliary imaging methods. This makes it difficult to comprehensively capture multi-angle information from electronic tags, resulting in incomplete and clear images of complex shapes or uniquely positioned tags. Blind spots are common, leading to missing or blurred content. Furthermore, it's difficult to flexibly adjust the lighting angle according to the tag material, shape, and shooting environment, easily causing reflections and shadows. This makes it difficult to clearly display key information such as text and barcodes, severely impacting image quality and information recognition accuracy, leading to increased defect rates. Therefore, we propose an automated production line for electronic tag manufacturing. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide an automated production line for electronic tag manufacturing and processing. This solves the technical problems of excessive burrs and dimensional deviations caused by mold wear during the current electronic tag stamping process, which leads to generally poor traditional inspection results and increased defect rates.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated production line for electronic tag manufacturing, comprising a screen printing machine, a front shell assembly machine, a front shell hot melt machine, a first circulation line, a second circulation line, and a LOGO inspection machine, characterized in that the screen printing machine, the front shell assembly machine, the front shell hot melt machine, the first circulation line, and the second circulation line are used for automated production of electronic tags, and the LOGO inspection machine is used for post-production inspection and rework of defective products. The LOGO inspection machine includes a turntable, a photographing component, and a placement rack, with several placement racks equidistantly mounted on the turntable. The placement rack is used to drive the electronic tag to be inspected through the photographing component during rotation.

[0006] The camera assembly includes a three-axis drive frame and two cameras, which are respectively mounted on both sides of the three-axis drive frame, and the two cameras are located on both sides of the placement frame when the placement frame passes by.

[0007] Both sides of the three-axis drive frame are provided with auxiliary mirror components, which include flexible mirrors. The flexible mirrors are used to provide the effect of reflecting the electronic tag image or reflecting light to illuminate the electronic tag when taking pictures.

[0008] Auxiliary lighting components are provided on both sides of the three-axis drive frame. The auxiliary lighting components include lamps. The lamps can rotate at an angle of no more than 180° relative to the flexible mirror and the electronic tag. The lamps are used to provide auxiliary lighting to reflect the image or reflect light to illuminate the electronic tag when taking pictures.

[0009] Preferably, positioning rings are installed on both sides of the three-axis drive frame. The positioning rings are provided with a rotating structure, which consists of a first rotary drive, a gear, a gear ring, and a mounting ring.

[0011] Preferably, the mounting ring is provided with a lifting structure, which consists of a first linear drive, a slide groove, a slide rod, a guide block, a first guide groove, a fixing plate, a guide rod, and a second guide groove;

[0013] Preferably, an angle adjustment arm is installed on the guide rod, and the rotatable angle of the angle adjustment arm is no more than 180°.

[0014] Preferably, the first guide groove has an arc-shaped structure, and when the guide block moves to the end of the first guide groove, the flexible mirror surface is facing the side of the electronic tag.

[0015] Preferably, the flexible mirror is disposed in the gap at the front end of the mirror frame, and a traction post is provided at the rear of the flexible mirror. The traction post is connected to the output end of a second linear drive, and the second linear drive is installed in the mirror frame. Traction cables are connected to both sides of the flexible mirror. The traction cables are wound with a winding post, and the winding post is rotatably connected in the mirror frame. The winding post is connected to the output end of a second rotary drive, and the second rotary drive is installed on the mirror frame.

[0016] Preferably, the flexible mirror is a deformable structure, comprising a convex state, a planar state, and a concave state. When the flexible mirror is in the convex state, the traction column extends forward, the traction cable relaxes, and the convex state provides the effect of reflecting images and light. When the flexible mirror is in the planar state, the traction column is stationary, the traction cable is taut, and the planar state provides the effect of reflecting images and light. When the flexible mirror is in the concave state, the traction column retracts backward, the traction cable relaxes, and the concave state provides the effect of reflecting images and light.

[0017] Preferably, a deformation layer is installed on the rear part of the flexible mirror. The deformation layer has several vertical deformation grooves equidistantly spaced on it, and the deformation grooves are parallel to the bending direction of the flexible mirror. The deformation grooves are V-shaped grooves. Several electrically conductive deformation strips are installed on the deformation layer, and the electrically conductive deformation strips are perpendicular to the deformation grooves. The electrically conductive deformation strips are made of electrically conductive shape memory metal. The several electrically conductive deformation strips are divided into two groups. One group of the electrically conductive deformation strips has a convex arc plate structure when energized, and the other group of the electrically conductive deformation strips has a concave arc plate structure when energized. Both groups of the electrically conductive deformation strips have a straight plate structure when not energized.

[0018] Preferably, the lamp is mounted on the connector via a connecting shaft, and the two connectors are slidably connected to the upper and lower parts of the mirror frame, respectively. The connecting shaft is connected to the output end of a transmission device, the transmission device is connected to the output end of a third rotary drive, the third rotary drive is connected to a mounting bracket, the mounting bracket is mounted on the connector, the mounting bracket is connected to the output end of a third linear drive, and the third linear drive is mounted on the mirror frame.

[0019] Preferably, when the flexible mirror is in a planar state, when facing the flexible mirror, the lamp is at a 45° angle to the mirror and tilted towards the mirror, the lamp is 100-150mm away from the edge of the mirror, and the light source emission direction is towards the center of the mirror; when facing the electronic tag, the lamp is at a 30° angle to the surface of the electronic tag, and the lamp is 80-120mm away from the electronic tag.

[0020] When the flexible mirror is in a convex state, when facing the flexible mirror, the light fixture's emission direction is tilted outward by 20° and towards the center of the mirror's arc surface. The distance between the light fixture and the mirror is 150-200mm, and the distance is inversely proportional to the curvature of the convex surface. When facing the electronic tag, the light fixture forms a 45° angle with the normal of the electronic tag's arc surface. The distance between the light fixture and the electronic tag is 100-150mm, and the distance is inversely proportional to the curvature of the convex surface.

[0021] When the flexible mirror is in a concave state, when facing the flexible mirror, the lamp is tilted 60° toward the center of the mirror and close to the focal point of the concave mirror, and the lamp is 80-120mm away from the mirror; when facing the electronic tag, the lamp is perpendicular to the electronic tag, and the lamp is 50-80mm away from the electronic tag.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In the inspection process of electronic tags during production, this invention optimizes the integrated inspection equipment. During the inspection of electronic tags, a flexible mirror assisted by a lamp reflects the image of the electronic tag, allowing simultaneous detection of both sides of the tag. The lamp also illuminates detailed defects within the tag. This invention optimizes the inspection effect during the stamping process, enabling more accurate defect detection and timely rework of defective electronic tags, thus improving production quality.

[0024] 2. This invention integrates a rotating structure and a lifting structure into the positioning ring and mounting ring of a three-axis drive frame. In the rotating structure, a first rotary drive drives a gear to rotate. Through the meshing transmission between the gear and the gear ring, the mounting ring rotates 360° without dead angles, thereby rotating and adjusting the position of the auxiliary mirror assembly. Simultaneously, through the first linear drive of the lifting structure, the guide rod can achieve arc-shaped displacement along the first guide groove in the vertical direction via the cooperation of the sliding groove and the sliding rod. This allows the auxiliary mirror assembly to form an arc-shaped image reflection and lighting effect without changing its angle. This invention, through the rotating and lifting structures, enables the auxiliary mirror assembly to rotate while simultaneously making arc-shaped displacement along a straight line, thus creating an arc-shaped image reflection and lighting effect during movement, optimizing the shooting effect.

[0025] 3. This invention utilizes a deformable flexible mirror surface, allowing for adjustment in multiple states. When a convex mirror effect is desired, the second linear drive controls the traction column to push forward, while the second rotary drive releases the traction cable on the winding column. The flexible mirror surface naturally convexes under the thrust of the traction column, enabling imaging over a wide viewing angle. In the planar state, the traction column remains stationary, and the traction cable, through the tightening action of the winding column, tauts and straightens the flexible mirror surface. At this point, the reflected light is stable and parallel, providing a clear and undistorted image. When switching to the concave state, the traction column retracts backward, and the traction cable releases simultaneously, causing the flexible mirror surface to concave and focus the light. This invention, through the deformable design of the flexible mirror surface, allows the mirror structure to form various images, thereby further optimizing the photographic effect, expanding the types of photos captured, and thus increasing the data sample size.

[0026] 4. This invention, through the design of a deformation layer structure on the rear of the flexible mirror, provides a preset path for the mirror's bending via equidistant V-shaped deformation grooves. This ensures that the flexible mirror maintains a regular curved surface when switching between convex, planar, and concave surfaces, preventing distortion or localized wrinkles caused by uneven stress, thus avoiding reflection distortion. Furthermore, when the mirror's shape needs to be changed, electrically conductive deformation strips made of shape-memory metal come into play: two sets of differently shaped strips work together, rapidly transforming into convex or concave arc plate structures after being energized, pushing or pulling the flexible mirror to achieve precise surface shaping by the auxiliary traction column. This invention, by designing a deformation layer structure, ensures that the flexible mirror maintains a regular curved surface during deformation. Simultaneously, the cooperation of the electrically conductive deformation strips assists in the precise surface shaping of the flexible mirror when stretched by the traction column, effectively guaranteeing the clarity and stability of the mirror's reflection under different shapes.

[0027] 5. This invention allows the lamp to adjust its illumination effect in accordance with the changes in the flexible mirror surface. The third rotary drive, in conjunction with the transmission device, enables the lamp to rotate freely from 0-360° in both horizontal and vertical directions. Combined with the third linear drive's linear sliding on the mirror frame, this ensures the lamp can quickly position itself to the target angle and distance. When the flexible mirror is in a flat state, the lamp is adjusted by the transmission device to a 45° angle with the mirror, 100mm from the edge. Light is projected onto the mirror at a scientifically controlled angle, and after reflection, forms a uniform and soft illumination layer, effectively eliminating mirror reflections and vignetting, resulting in a clear, shadow-free image and ensuring an undisturbed visual experience for the user. When switching to a convex state, the lamp maintains the same angle and distance from the center of the mirror's curved surface, preventing localized over-brightness caused by focused light. The excessive reflection caused by the mirror surface is mitigated by uniform light coverage, ensuring clear visibility of details throughout the mirror and effectively enhancing its visual appeal. When the mirror transforms into a concave shape, the light fixture quickly tilts 60° and moves closer to the focal point, utilizing the light-focusing properties of the concave mirror to concentrate light onto key areas of the mirror, achieving high-intensity directional illumination and enhancing the contrast and clarity of the mirror display. Even in complex lighting environments, the mirror ensures a clear and sharp image. For electronic tag lighting needs, the light fixture can also automatically switch angles and distances according to the mirror shape: in a flat state, it projects light at a 30° angle and a distance of 80mm to ensure clear label readability; in a convex state, it forms a 45° angle with the label's curved surface normal, achieving uniform lighting on the curved surface; in a concave state, it illuminates vertically at a close distance of 50mm to ensure sufficient illumination for the label. This invention, through the design of a lighting system adapted to the deformable state of the flexible mirror, significantly improves the lighting effect and optimizes the usability of the variable mirror and the shooting effect of the camera.

[0052] Example 1, such as Figures 8 to 9As shown, this invention relates to an automated production line for electronic tag manufacturing, comprising a screen-swiping machine, a front shell assembly machine, a front shell hot-melt machine, a first circulation line, a second circulation line, and a logo inspection machine. The screen-swiping machine, front shell assembly machine, front shell hot-melt machine, first circulation line, and second circulation line are used for automated production of electronic tags. The logo inspection machine is used for post-production inspection and rework of defective products. The logo inspection machine includes a turntable 60, a photographing component 61, and four placement racks 62 equidistantly mounted on the turntable 60. The placement racks 62 drive the electronic tags to be inspected as they rotate past the photographing component 61. The photographing component 61 includes a three-axis drive frame 63 and... Two cameras 64 are respectively mounted on both sides of the three-axis drive frame 63, and the two cameras 64 are located on both sides of the placement frame 62 when the frame 62 passes by; auxiliary mirror components 65 are provided on both sides of the three-axis drive frame 63, and the auxiliary mirror components 65 include flexible mirrors 66, which are used to provide the effect of reflecting the electronic tag image or reflecting light to illuminate the electronic tag when taking pictures; auxiliary lighting components 67 are provided on both sides of the three-axis drive frame 63, and the auxiliary lighting components 67 include lamps 68, which have a rotation angle of no more than 180° relative to the flexible mirrors 66 and the electronic tag, and are used to provide auxiliary lighting to reflect the image or reflect light to illuminate the electronic tag when taking pictures.

[0053] This invention, during the inspection of electronic tags after their formation, employs a three-axis drive frame 63 with cameras 64 mounted on both sides in the imaging component 61. This, combined with the flexible mirror 66 of the auxiliary mirror component 65 and the rotatable lamp 68 of the auxiliary lighting component 67, allows the flexible mirror 66 to reflect the electronic tag image during imaging. This reflection assists the camera 64 in capturing the image, enabling it to simultaneously capture both sides of the electronic tag. Furthermore, the lamp 68 illuminates the tag, making it easier for the camera 64 to capture detailed images. Through the combined use of the flexible mirror 66 and the lamp 68, this invention can illuminate the electronic tag during imaging, optimizing the shooting effect, or expand the shooting range of the camera 64 by reflecting the electronic tag image through the mirror, achieving an optimized imaging result.

[0054] This invention optimizes the integrated inspection equipment during the production of electronic tags. By using a flexible mirror assisted by a lamp 68 to reflect the image of the electronic tag, both sides of the tag can be detected simultaneously. Furthermore, the lamp 68 illuminates detailed defects within the tag. This invention optimizes the inspection effect during the stamping process, enabling more accurate defect detection and timely rework of defective electronic tags, thus improving production quality.

[0055] Specifically, such as Figures 10 to 11As shown, the three-axis drive frame 63 of the present invention is equipped with positioning rings 69 on both sides. The positioning rings 69 are provided with a rotating structure, which consists of a first rotary drive 70, a gear 71, a gear ring 72, and a mounting ring 73. The first rotary drive 70 is mounted on the positioning ring 69, the gear 71 is mounted on the output end of the first rotary drive 70, the gear ring 72 is rotatably connected to the outside of the positioning ring 69, and the top end of the gear ring 72 is meshed with the gear 71. The mounting ring 73 is rotatably connected to the outside of the positioning ring 69, and the mounting ring 73 is fixedly connected to the gear ring 72.

[0056] The mounting ring 73 is provided with a lifting structure, which consists of a first linear drive 74, a sliding groove 75, a sliding rod 76, a guide block 77, a first guide groove 78, a fixing plate 79, a guide rod 80, and a second guide groove 81. The first linear drive 74 is mounted on the mounting ring 73, the sliding groove 75 is mounted on the output end of the first linear drive 74, the sliding rod 76 is slidably connected to the sliding groove 75, the guide block 77 is mounted on the sliding rod 76 and is slidably connected to the first guide groove 78, the first guide groove 78 is opened on the fixing plate 79 and the fixing plate 79 is mounted on the top of the mounting ring 73, the guide rod 80 is mounted on the sliding rod 76 and is slidably connected to the second guide groove 81 and the second guide groove 81 is opened on the top of the mounting ring 73.

[0057] An angle adjustment arm 82 is installed on the guide rod 80, and the rotatable angle of the angle adjustment arm 82 is no more than 180°.

[0058] The first guide groove 78 has an arc-shaped structure. When the guide block 77 moves to the end of the first guide groove 78, the flexible mirror 66 faces the side of the electronic tag.

[0059] This invention incorporates a rotating and lifting structure on the mounting component of the auxiliary mirror assembly 65. In the rotating structure, a first rotation drive 70 drives a gear 71 to rotate. Through the meshing transmission between the gear 71 and the gear ring 72, the mounting ring 73 rotates 360° without any dead angle, thereby allowing the auxiliary mirror assembly 65 to rotate and adjust its position. Simultaneously, through the lifting structure, a first linear drive 74, in cooperation with a sliding groove 75 and a sliding rod 76, enables the guide rod 80 to perform arc-shaped displacement along the vertical first guide groove 78. This allows the auxiliary mirror assembly 65 to form an arc-shaped image reflection and lighting effect without changing its angle. This invention, through the rotating and lifting structures, enables the auxiliary mirror assembly 65 to rotate while simultaneously performing arc-shaped displacement along a straight line, thus creating an arc-shaped image reflection and lighting effect during movement, optimizing the shooting effect.

[0060] It is worth noting that, such as Figures 12 to 22As shown, the flexible mirror 66 of the present invention is disposed in the gap at the front end of the mirror frame 83. The rear part of the flexible mirror 66 is provided with a traction post 84. The traction post 84 is connected to the output end of the second linear drive 85, and the second linear drive 85 is installed inside the mirror frame 83. Both sides of the flexible mirror 66 are connected with traction cables 86. The traction cables 86 are wound with a winding post 87, and the winding post 87 is rotatably connected inside the mirror frame 83. The winding post 87 is connected to the output end of the second rotary drive 88, and the second rotary drive 88 is installed on the mirror frame 83.

[0061] The flexible mirror 66 is a deformable structure, including a convex state, a planar state, and a concave state. When the flexible mirror 66 is in the convex state, the traction column 84 pushes forward, and the traction cable 86 is relaxed. The convex state is used to provide the effect of reflecting images and light from a convex mirror. When the flexible mirror 66 is in the planar state, the traction column 84 is stationary, and the traction cable 86 is taut. The planar state is used to provide the effect of reflecting images and light from a planar mirror. When the flexible mirror 66 is in the concave state, the traction column 84 retracts backward, and the traction cable 86 is relaxed. The concave state is used to provide the effect of reflecting images and light from a concave mirror.

[0062] This invention designs a deformable flexible mirror 66 based on the auxiliary mirror assembly 65. This flexible mirror can be adjusted in multiple states. When a convex mirror effect is needed, the second linear drive 85 controls the traction column 84 to push forward, while the second rotary drive 88 releases the traction cable 86 on the winding column 87. The flexible mirror 66 naturally convexes under the thrust of the traction column 84, enabling imaging over a wide viewing angle. In the planar state, the traction column 84 remains stationary, and the traction cable 86 is tightened by the winding column 87, keeping the flexible mirror 66 taut and straight. At this time, the reflected light is stable and parallel, providing a clear and undistorted image. When switching to the concave state, the traction column 84 retracts backward, and the traction cable 86 releases simultaneously, causing the flexible mirror 66 to concave and focus the light. This invention, through the deformable design of the flexible mirror 66, allows the mirror structure to form various images, thereby further optimizing the photographic effect, expanding the types of photos taken, and thus increasing the data sample.

[0063] Furthermore, such as Figure 14 As shown, the flexible mirror 66 involved in this invention has a deformation layer 89 installed on its rear part. Twenty vertical deformation grooves 90 are equally spaced on the deformation layer 89, and the deformation grooves 90 are parallel to the bending direction of the flexible mirror 66. The deformation grooves 90 are V-shaped grooves. Several electrically conductive deformation strips 91 are installed on the deformation layer 89, and the electrically conductive deformation strips 91 are perpendicular to the deformation grooves 90. The electrically conductive deformation strips 91 are made of electrically conductive shape memory metal. The two electrically conductive deformation strips 91 are divided into two groups. One group of electrically conductive deformation strips 91 has a convex arc plate structure when energized, and the other group of electrically conductive deformation strips 91 has a concave arc plate structure when energized. Both groups of electrically conductive deformation strips 91 have a straight plate structure when not energized.

[0064] This invention, through the design of a deformation layer 89 structure at the rear of the flexible mirror 66 and the provision of a preset path for the bending of the mirror surface via equidistantly distributed V-shaped deformation grooves 90, ensures that the flexible mirror 66 maintains a regular curved surface when switching between convex, planar, and concave surfaces. This prevents distortion or localized wrinkling due to uneven force, thus avoiding distortion of the reflection effect. Furthermore, when the mirror shape needs to be changed, electrically conductive deformation strips 91 made of shape-memory metal come into play: two sets of electrically conductive deformation strips 91 with different shapes cooperate, rapidly transforming into convex or concave arc plate structures after being energized, pushing or pulling the flexible mirror 66 to achieve the fine surface shaping of the auxiliary traction column 84. By designing the deformation layer 89 structure, this invention ensures that the flexible mirror 66 maintains a regular curved surface during deformation. Simultaneously, the cooperation of the electrically conductive deformation strips 91 assists in the fine surface shaping of the flexible mirror 66 when stretched by the traction column 84, effectively guaranteeing the clarity and stability of the mirror reflection under different shapes.

[0065] Furthermore, such as Figures 12 to 22 As shown, the lamp 68 of the present invention is mounted on the connector 92 via a connecting shaft 93, and the two connectors 92 are slidably connected to the upper and lower parts of the mirror frame 83, respectively. The connecting shaft 93 is connected to the output end of the transmission device 94, the transmission device 94 is connected to the output end of the third rotary drive 95, the third rotary drive 95 is connected to the mounting bracket 96, the mounting bracket 96 is mounted on the connector 92, the mounting bracket 96 is connected to the output end of the third linear drive 97, and the third linear drive 97 is mounted on the mirror frame 83.

[0066] When the flexible mirror 66 is in a flat state, when facing the flexible mirror 66, the lamp 68 is at a 45° angle to the mirror and tilted towards the mirror, the lamp 68 is 100mm away from the edge of the mirror, and the light source is emitted towards the center of the mirror; when facing the electronic tag, the lamp 68 is at a 30° angle to the surface of the electronic tag, and the lamp 68 is 80mm away from the electronic tag.

[0067] When the flexible mirror 66 is in a convex state, when facing the flexible mirror 66, the light fixture 68's emission direction is tilted outward by 20° and towards the center of the mirror's arc surface. The light fixture 68 is 150mm away from the mirror, and the distance is inversely proportional to the curvature of the convex surface. When facing the electronic tag, the light fixture 68 forms a 45° angle with the normal of the electronic tag's arc surface. The light fixture 68 is 100mm away from the electronic tag, and the distance is inversely proportional to the curvature of the convex surface.

[0068] When the flexible mirror 66 is in a concave state, when facing the flexible mirror 66, the lamp 68 is tilted 60° toward the center of the mirror and close to the focal point of the concave mirror, and the lamp 68 is 80mm away from the mirror; when facing the electronic tag, the lamp 68 is perpendicular to the electronic tag, and the lamp 68 is 50mm away from the electronic tag.

[0069] The present invention enables the lamp 68 to adjust the illumination effect of the light by cooperating with the changes of the flexible mirror 66. The third rotary drive 95 and the transmission device 94 work together to enable the lamp 68 to rotate freely from 0 to 360° in the horizontal and vertical directions. Combined with the linear sliding of the third linear drive 97 on the mirror frame 83, the lamp 68 can be quickly positioned to the target angle and distance.

[0070] When the flexible mirror 66 is in a flat state, the lamp 68 is adjusted by the transmission device 94 to a position at a 45° angle to the mirror and 100mm away from the edge of the mirror. The light is projected onto the mirror at a scientific incident angle, and after reflection, it forms a uniform and soft lighting layer, effectively eliminating mirror reflections and vignetting, making the mirror image clear and shadow-free, and ensuring that the user has an undisturbed visual experience. When switching to a convex state, the lamp 68 is kept at the same angle and distance from the center of the curved surface of the mirror to avoid excessive reflection caused by local over-brightness due to light focusing. The uniform light coverage ensures that details in all parts of the mirror are clearly distinguishable, effectively improving the visibility of the mirror. When the mirror is converted to a concave shape, the lamp 68 quickly tilts 60° and moves closer to the focal point. Utilizing the light-focusing characteristics of the concave mirror, the light is concentrated and projected onto the key areas of the mirror to achieve high-intensity directional lighting, enhancing the contrast and clarity of the mirror display. Even in complex lighting environments, the mirror can ensure that it presents a clear and sharp image.

[0071] To meet the lighting needs of electronic tags, the luminaire 68 can automatically switch angles and distances according to the shape of the mirror: in a flat state, it projects light at a 30° angle and a distance of 80mm to ensure clear readability of the tag; in a convex state, it forms a 45° angle with the normal to the curved surface of the tag to achieve uniform lighting on the curved surface; in a concave state, it illuminates vertically at a close distance of 50mm to ensure sufficient illumination for the tag. This invention significantly improves the lighting effect and optimizes the use of the variable mirror and the shooting effect of the camera 64 by designing a luminaire 68 system that adapts to the deformable state of the flexible mirror 66.
