Description

Technical Field

[0001] This utility model relates to the field of photographic auxiliary equipment technology, and in particular discloses a lighting platform that facilitates clear photography. Background Technology

[0002] In many stages of industrial production involving photographic inspection of rolled materials, such as printing quality inspection and packaging material surface defect detection, traditional lighting platforms and related equipment have revealed a series of problems that urgently need to be addressed. Regarding imaging effects, past lighting platforms mostly employed a planar design, resulting in extremely uneven light reflection on the rolled material surface, frequently producing areas of excessive glare or darkness. Simultaneously, during the transport process, the lack of effective flattening measures easily leads to deformations such as wrinkles, bends, or curls, causing abnormal light scattering and refraction. This severely interferes with the imaging effect of the photographic equipment, significantly reducing the clarity and accuracy of the acquired images, failing to meet the requirements of high-precision inspection, and consequently affecting the reliability of the inspection results.

[0003] From the perspective of equipment operational stability, traditional power transmission systems have significant defects. The roller rotation is not smooth enough, which directly leads to inconsistent speeds of the rolled material during transport, frequently resulting in problems such as deviation and slack. Furthermore, the reliability of the clamping device is insufficient; the rolled material is prone to loosening and displacement during transport, making precise positioning difficult and hindering continuous, efficient photographic inspection, significantly reducing production efficiency. In terms of operation and maintenance, traditional clamping methods rely heavily on manual operation. This method is not only inefficient, but also prone to inconsistent clamping force and angle among different operators, leading to poor clamping stability. In addition, the overall structural design of the equipment is not reasonable, and the versatility of components is poor. Once a malfunction occurs, repairs are difficult and costly, with long downtimes, severely impacting production schedules. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a lighting platform that facilitates clear photography.

[0005] To achieve the above objectives, this utility model provides a lighting platform for clear photography, comprising a frame, a first roller and a second roller rotatably mounted on the frame, and a drive assembly for driving the two rollers to rotate. The rotation axes of the first roller and the second roller are parallel to each other, with the rotation axis of the first roller located obliquely above the rotation axis of the second roller. The roll material abuts against the outer periphery of the first roller and the second roller. The drive assembly drives the two rollers to rotate, thereby moving the roll material. The frame is provided with an arc-shaped guide platform for abutting against the roll material located between the two rollers and facilitating clear photography by the photographing equipment.

[0006] Furthermore, a third roller is rotatably mounted on the frame. The third roller is provided with a spreading thread for flattening the coiled material. The spreading thread extends spirally around the central axis of the third roller and along the length of the third roller.

[0007] Furthermore, the spreading thread is formed by protrusion from the surface of the roller or by winding rope material.

[0008] Furthermore, there are two spreading threads, with opposite helical directions, extending from the middle of the third roller to the end of the third roller.

[0009] Furthermore, a circulating transmission assembly is movably provided on the frame. The circulating transmission assembly has multiple transmission wheels rotatably arranged on the frame and an annular transmission belt sleeved on the outer circumference of the multiple transmission wheels. The drive assembly has a drive motor arranged on the frame. The multiple transmission wheels are respectively connected to the first roller, the second roller and the output shaft of the drive motor. The drive motor drives the first roller and the second roller to rotate via the transmission wheels and the annular transmission belt.

[0010] Furthermore, the annular transmission belt is provided with a clamping assembly, which has a first clamping plate disposed on the annular transmission belt and a second clamping plate rotatably disposed on the first clamping plate. The second clamping plate cooperates with the first clamping plate to clamp the roll material. The driving assembly drives the clamping assembly via the circulating transmission assembly to move the roll material from the unwinding end to the winding end.

[0011] Furthermore, the frame is equipped with a light box and a photographic cover that work in conjunction with the arc-shaped material guide platform. The light box provides a light source for the arc-shaped material guide platform, and the photographic cover is located above the arc-shaped material guide platform. The photographic device inside the photographic cover takes a picture of the coiled material forming the arc-shaped material guide platform with the help of the light source of the light box.

[0012] Furthermore, the frame is provided with a pushing component for clamping materials in conjunction with the driving clamping component. The pushing component has a cylinder mounted on the frame, and the output end of the cylinder is provided with a pushing component. The cylinder drives the pushing component to rotate the second clamping plate relative to the first clamping plate to achieve the clamping operation.

[0013] Furthermore, the frame is equipped with a sensor for taking pictures of the arc-shaped material guide platform in conjunction with the photographing equipment, and the sensor is located below the arc-shaped material guide platform.

[0014] Furthermore, a rotating shaft is rotatably provided on the first clamping plate, the rotating shaft is connected to the second clamping plate, and a rotating component is provided at the end of the rotating shaft. The rotating component is driven manually or by an external device to realize the clamping operation of the second clamping plate relative to the first clamping plate.

[0015] The beneficial effects of this utility model are:

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] Please see Figures 1 to 6 As shown, this utility model provides a lighting platform for clear photography, comprising a frame 1, a first roller 2 and a second roller 3 rotatably mounted on the frame 1, and a drive assembly 4 for driving the two rollers to rotate. The rotation axes of the first roller 2 and the second roller 3 are parallel to each other, and the rotation axis of the first roller 2 is located obliquely above the rotation axis of the second roller 3. The rolled material abuts against the outer periphery of the first roller 2 and the second roller 3. The drive assembly 4 drives the two rollers to rotate, thereby moving the rolled material. The frame 1 is provided with an arc-shaped guide platform 5 for abutting against the rolled material located between the two rollers and facilitating clear photography by the photography equipment.

[0028] In actual use, the rotation axes of the two rollers are parallel to each other, and the rotation axis of the first roller 2 is located diagonally above the rotation axis of the second roller 3. This arrangement allows the roll material to form a specific tension and curvature between them, which is beneficial for the stable transmission of the roll material. By contacting the outer periphery of the roll material, it can stably drive the roll material to move under the drive component 4, providing power for the continuous movement of the subject during shooting, ensuring the continuity and consistency of the captured image, and avoiding blurry images caused by unstable roll material transmission. The contact between the roll material located between the two rollers causes the roll material to form a specific arc shape on the platform, which can naturally adjust the angle of the subject according to shooting needs, helping the photography equipment to obtain the best shooting angle, fully displaying the features of the subject, reducing blind spots, and improving the clarity and completeness of the image. The arc-shaped structure of the arc-shaped guide platform can better reflect and scatter light. Compared with a planar structure, it is more conducive to the even distribution of light on the subject, reducing the occurrence of shadows and reflections, making the details of the subject more clearly visible, and greatly improving the clarity and quality of the image captured by the photography equipment.

[0029] Specifically, a third roller 6 is rotatably mounted on the frame 1. The third roller 6 is provided with a spreading thread 7 for flattening the rolled material. The spreading thread 7 is arranged to spirally extend around the central axis of the third roller 6 and along the length of the third roller 6.

[0030] In actual use, the spreading thread 7 is spirally extended along the length of the third roller 6 around its central axis. When the coiled material contacts the third roller 6 and moves with the rotation of the roller, the spreading thread 7 exerts a gradually unfolding force on the coiled material. Like a spiral guide rail, it gradually stretches the coiled material along the length of the roller, effectively flattening it. The third roller 6, rotatably mounted on the frame 1, has a relatively fixed position and makes efficient use of the space in the frame 1. This design makes the entire equipment more compact in layout. The spreading thread 7 is located on the third roller 6, eliminating the need for additional complex flattening devices that occupy too much space, which is beneficial for miniaturization or integrating more functional modules within a limited space. Because the spreading thread 7 is spirally extended, it can adapt to coiled materials of different widths and thicknesses. For wider coiled materials, the spiral spreading thread 7 can simultaneously apply unfolding force from the center and edges of the coiled material, ensuring that the entire width of the coiled material is evenly flattened. For thicker coiled materials, this continuous spiral structure can also flatten them through gradual stretching without damaging the coiled material by applying excessive force at once. The spreading thread 7, centered on the central axis of the roller, ensures a uniform distribution of flattening force during roller rotation. Because the relative movement of each position of the spreading thread 7 relative to the coiled material is regular and stable during roller rotation, the force exerted on the coiled material during unfolding is relatively uniform in both time and space, thus achieving a stable flattening process and reducing the occurrence of wrinkles or tears in the coiled material during flattening.

[0031] Specifically, the spreading thread 7 is formed by protrusion from the surface of the roller or by winding rope material.

[0032] In practical use, the spreading thread 7 can be formed either by protruding onto the roller surface or by winding rope, providing two different manufacturing methods. Manufacturers with varying production conditions and technological advantages can choose the appropriate processing method based on their equipment, technical capabilities, and cost considerations. This flexibility helps improve production efficiency; different processing methods can be applied concurrently to different batches or specifications of rollers, quickly meeting diverse market demands for polishing platforms and shortening production cycles. When the spreading thread 7 is formed by winding rope, it offers a degree of adjustability. The winding density and angle of the rope can be flexibly adjusted according to the material and thickness of the coil, as well as the required flattening force. Regardless of the method used to form the spreading thread 7, as long as it is manufactured according to a reasonable design and process, it can stably perform its function of flattening the coil. The convexly formed spreading thread 7 has good integration with the roller and a solid structure. It is not prone to loosening or deformation during long-term use and can continuously and stably provide a flattening force for the coiled material. Although the spreading thread 7 formed by rope winding has a slightly weaker overall structure, it can also reliably apply a flattening force when the coiled material passes through by appropriate fixing methods (such as glue bonding, strap reinforcement, etc.), achieving a stable spreading effect and ensuring that the coiled material is in a flat state when photographed later, thereby improving the clarity and accuracy of the photograph.

[0033] Specifically, there are two spreading threads 7, and the two spreading threads 7 have opposite helical directions. The spreading threads 7 extend from the middle of the third roller 6 to the end of the third roller 6.

[0034] In practical use, the two opposing spiral threads 7 allow the material to be subjected to two opposite forces simultaneously during the rotation of the third roller 6. This promotes more even and rapid spreading of the material towards the roller end, significantly improving spreading efficiency compared to a single thread. It ensures a more comprehensive and uniform distribution of material on the roller, which is beneficial for subsequent processing. The opposing spiral forces counterbalance each other, preventing excessive stretching, deformation, or even damage to the material due to excessive force in one direction, thus better preserving the material's physical properties and integrity. Different materials may have different properties such as viscosity and softness. This double-thread design with opposite spiral directions can adapt to the spreading needs of various materials to a certain extent, enhancing the equipment's versatility for different types of materials.

[0035] Specifically, a circulating transmission assembly 8 is movably provided on the frame 1. The circulating transmission assembly 8 has multiple transmission wheels 81 rotatably arranged on the frame 1 and an annular transmission belt 82 sleeved on the outer periphery of the multiple transmission wheels 81. The drive assembly 4 has a drive motor 41 arranged on the frame 1. The multiple transmission wheels 81 are respectively connected to the first roller 2, the second roller 3 and the output shaft of the drive motor 41. The drive motor 41 drives the first roller 2 and the second roller 3 to rotate via the transmission wheels 81 and the annular transmission belt 82.

[0036] In actual use, the circulating transmission assembly 8, through the cooperation of multiple transmission wheels 81 and annular transmission belt 82, can smoothly and evenly transmit the power of the drive motor 41 to the first roller 2 and the second roller 3. The annular transmission belt 82 has a certain degree of flexibility, which can effectively buffer and absorb the impact force generated by motor starting, stopping, or load changes during transmission, avoiding damage to the rollers caused by sudden changes in power transmission, ensuring the stability of roller rotation, and thus making the movement of the roll material on the arc-shaped guide platform 5 smoother and more stable, which is beneficial for the imaging equipment to obtain clear and continuous images. The arrangement of multiple transmission wheels 81 rationally distributes the tension of the transmission belt, allowing the transmission belt to fit tightly with each transmission wheel 81, reducing the probability of slippage. In this way, the power of the drive motor 41 can be efficiently converted into the rotational power of the rollers, ensuring that the roll material moves stably at the set speed, improving the working efficiency and reliability of the entire lighting platform. With the help of the circulating transmission assembly 8, the first roller 2 and the second roller 3 can achieve synchronous rotation. Because they are driven by a common drive wheel 81 and an annular drive belt 82, they maintain good coordination during rotation, and their speeds and directions of rotation can be precisely matched. This is crucial for the smooth conveying of the roll material between the two rollers and the stable formation of the arc-shaped guide platform 5, avoiding problems such as roll material stretching, wrinkling, or deviation caused by inconsistent roller speeds. It provides uniform and consistent conveying conditions for the roll material, which helps to improve the quality and accuracy of the photographs.

[0037] Specifically, the annular transmission belt 82 is provided with a clamping assembly 9. The clamping assembly 9 has a first clamping plate 91 disposed on the annular transmission belt 82 and a second clamping plate 92 rotatably disposed on the first clamping plate 91. The second clamping plate 92 cooperates with the first clamping plate 91 to clamp the roll material. The driving assembly 4 drives the clamping assembly 9 to move the roll material from the unwinding end to the winding end via the circulating transmission assembly 8.

[0038] In actual use, the first clamping plate 91 and the rotating second clamping plate 92 in the clamping assembly 9 cooperate to form a stable clamping effect on the rolled material. As the drive assembly 4 moves the clamping assembly 9 through the circulating transmission assembly 8, the rolled material is firmly clamped, effectively preventing loosening, slippage, or deviation during transport. This allows the rolled material to be smoothly and accurately transported from the unwinding end to the rewinding end along a predetermined path, ensuring the continuity and stability of the rolled material transport on the entire lighting platform. This provides a stable subject for the photography equipment, contributing to the acquisition of clear, high-quality photos. Compared to some methods that rely solely on the friction between the rolled material and the rollers for transport, the clamping effect of the clamping assembly 9 is more reliable. Especially for rolled materials that are relatively thin, smooth, or have a certain degree of elasticity, it better overcomes the problem of displacement during transport, ensuring that the rolled material is always in the appropriate position and posture for photography. Because the clamping assembly 9 can tightly clamp the rolled material, the transport position of the rolled material can be precisely controlled under the drive of the circulating transmission assembly 8. The clamping method of the first clamping plate 91 and the second clamping plate 92 offers a degree of flexibility. By adjusting parameters such as the clamping plate spacing and clamping force, it can adapt to rolls of material with different thicknesses, widths, and materials. For thicker rolls, the clamping plate spacing can be increased and the clamping force strengthened; while for thinner rolls, the spacing can be reduced and a gentler clamping method used to avoid damage. This adjustability allows the clamping assembly 9 to be widely used in various industrial production processes involving rolls of material, such as paper, plastic film, and metal foil, enhancing the compatibility of the luminous platform with different rolls and expanding the equipment's applicability.

[0039] Specifically, the frame 1 is equipped with a light box 11 and a photographing cover 12 that cooperate with the arc-shaped material guiding platform 5. The light box 11 provides a light source for the arc-shaped material guiding platform 5, and the photographing cover 12 is located above the arc-shaped material guiding platform 5. The photographing device inside the photographing cover 12 takes a picture of the coiled material forming the arc-shaped material guiding platform 5 with the help of the light source of the light box 11.

[0040] In practical use, the lightbox 11 effectively isolates the shooting area from ambient light to a certain extent. In industrial production environments, various complex light sources exist, such as natural light and light emitted from other equipment. These ambient lights can interfere with the imaging effect of the photographic equipment on the coil material, leading to problems such as noise and reduced contrast. The relatively independent and concentrated light source provided by the lightbox 11 allows the shooting area to be primarily controlled by it, reducing the degree of ambient light interference and ensuring the purity and accuracy of the captured images. The photographic cover 12, located above the arc-shaped guide platform 5, creates a relatively enclosed and stable shooting space for the photographic equipment. This reduces interference from external factors such as dust and airflow, prevents dust from adhering to the surface of the coil material and affecting image clarity, and also prevents airflow from causing the coil material to shake. This allows the photographic equipment to operate in a relatively stable environment, contributing to the capture of clear and stable photos. The photographic equipment inside the photographic cover 12, using the light source of the lightbox 11, can accurately photograph the coil material forming the arc-shaped guide platform 5. The combination of the lightbox 11 and the photographing cover 12 ensures that the lighting and spatial conditions of the shooting area are controllable. The photographing device can stably and accurately photograph the roll material according to preset parameters, such as exposure time and sensitivity, improving the accuracy and consistency of image acquisition. Moreover, this combination structure facilitates orderly shooting of different positions and areas on the roll material, which is conducive to realizing an automated and continuous photographing inspection process. For example, when conducting comprehensive quality inspection of the roll material, it can ensure that images of each location can be accurately captured and analyzed, improving the efficiency and accuracy of the inspection.

[0041] Specifically, the frame 1 is provided with a pusher assembly 13 for clamping materials in conjunction with the drive clamping assembly 9. The pusher assembly 13 has a cylinder 131 set on the frame 1. The output end of the cylinder 131 is provided with a pusher 132. The cylinder 131 drives the pusher 132 to rotate the second clamping plate 92 relative to the first clamping plate 91 to realize the clamping operation.

[0042] In practical use, the method of using cylinder 131 to drive the pusher 132 transforms the traditional manual clamping operation into an automated operation. During equipment operation, there is no need for manual rotation of the second clamping plate 92 to clamp the material. Simply controlling the extension and retraction of cylinder 131 precisely and stably drives the pusher 132 to rotate the second clamping plate 92 relative to the first clamping plate 91, thus completing the clamping operation. This not only improves clamping efficiency and reduces the time cost of manual operation, but also avoids inconsistencies that may arise from manual operation, such as different clamping forces and angles by different operators. This ensures that each clamping operation is performed according to standard specifications, guaranteeing the stability and reliability of the coil clamping. As a drive element that can precisely control the stroke and output force, cylinder 131 can precisely adjust the movement of the pusher 132. The stroke and output pressure of cylinder 131 can be preset according to the different thicknesses and material characteristics of the coil, thereby achieving precise control of the rotation angle of the second clamping plate 92 and the clamping force. The cylinder 131 operates relatively smoothly and repeatably, and its output thrust does not fluctuate significantly during operation. This makes the clamping action more stable and smooth when the pusher 132 drives the second clamping plate 92 to rotate. Compared with some clamping methods that rely on elastic elements (such as springs) or simple manual mechanical structures, using the cylinder 131 can effectively avoid clamping instability caused by factors such as aging of elastic elements or improper manual operation. This ensures that the roll material is reliably clamped during the transfer process, reducing the probability of problems such as loosening or displacement of the roll material, and thus ensuring the smooth operation of the roll material conveying and photography work on the entire lighting platform.

[0043] Specifically, the frame 1 is equipped with a sensor 14 for taking pictures of the arc-shaped material guide platform 5 in conjunction with the photographing equipment. The sensor 14 is located below the arc-shaped material guide platform 5.

[0044] In practical use, sensor 14 can monitor the position and status information of the coiled material on the arc-shaped guide platform 5 in real time. When the coiled material moves to a specific position and meets the optimal conditions for taking a picture, sensor 14 can quickly send a trigger signal to the imaging device, enabling the imaging device to accurately take a picture at the appropriate time. For example, when it is necessary to take pictures of specific patterns, markings, or defective parts on the coiled material, sensor 14 can accurately determine whether it has reached the shooting area, ensuring that the imaging device can capture clear images of key parts every time, avoiding the omission of important information due to taking pictures too early or too late, and greatly improving the accuracy and effectiveness of the pictures. Through the automatic monitoring and triggering function of sensor 14, the entire picture-taking process does not require continuous human attention and manual operation to determine the timing of the picture, realizing the transformation of the picture-taking operation from manual to automated. This not only reduces labor costs and improves work efficiency, but also maintains a stable and consistent picture-taking trigger standard during long-term continuous production inspection, ensuring that each picture is acquired according to the preset requirements, further improving the automation level and overall work quality of the picture-taking process, and helping to create an efficient automated production inspection line. Sensor 14 can detect some status parameters of the arc-shaped material guide platform 5, such as the flatness of the platform and the degree of adhesion between the roll and the platform. If the platform experiences slight deformation or the roll exhibits abnormal undulations, sensor 14 can promptly sense and feedback relevant information. The imaging device can then adjust the shooting parameters (such as focal length and exposure time) accordingly to ensure that the quality of the captured image remains unaffected by these factors and remains clear and accurate. This avoids problems such as blurring and distortion of images caused by changes in the platform or roll state, improves the stability of image quality, and is beneficial for subsequent image analysis and quality inspection.

[0045] Specifically, a rotating shaft 93 is rotatably provided on the first clamping plate 91, and the rotating shaft 93 is connected to the second clamping plate 92. A rotating component 94 is provided at the end of the rotating shaft 93. The rotating component 94 is driven manually or by an external device to realize the clamping operation of the second clamping plate 92 relative to the first clamping plate 91.

[0046] In practical use, the clamping operation can be achieved by manually driving the rotating component 94, which is very useful in small-scale production scenarios, equipment debugging stages, or situations where ease of operation is crucial. Operators can intuitively control the rotation of the rotating component 94 based on the observed condition of the coil, thereby adjusting the position of the second clamping plate 92 to achieve the appropriate clamping force and angle. The operation is simple and easy to master, requiring no complex automated control system intervention, allowing for convenient and quick completion of clamping preparation. Simultaneously, the rotating component 94 can also be driven by external equipment, enabling the clamping assembly 9 to better integrate into automated production processes. For example, when connected to an automated control system, the rotation of the second clamping plate 92 can be precisely controlled according to preset programs and instructions, achieving collaborative work with the entire lighting platform. This meets the requirements for stable and precise clamping and transfer of coils in large-scale, continuous production, improving the applicability and flexibility of the equipment in different production modes. This diverse operating method can flexibly handle coils of different thicknesses and materials. For softer, thinner rolls, operators can manually and gently rotate the rotating component 94 to allow the second clamping plate 92 to rotate slowly and clamp the roll with minimal force, avoiding damage. For thicker, harder rolls, if an external device is used, appropriate drive parameters, such as torque and speed, can be set according to the characteristics of the roll to ensure that the second clamping plate 92 can apply sufficient clamping force to firmly hold the roll and ensure its stability during transport, allowing the clamping operation to adapt to various complex working conditions.

[0047] In this embodiment, a tensioning roller 15 for tensioning the rolled material is rotatably mounted on the frame 1, and the tensioning roller 15 is connected to the transmission wheel 81.

[0048] In actual use, the connection between the tension roller 15 and the transmission wheel 81 allows for flexible adjustment of the position or rotation state of the tension roller 15 using the rotational power of the transmission wheel 81, thereby applying appropriate tension to the roll material. In different production scenarios, the tension can be precisely adjusted according to actual needs for roll materials of different materials, thicknesses, and widths. For example, for thinner paper rolls that are prone to wrinkling, the tension can be appropriately increased to keep them flat during transport and prevent wrinkles caused by insufficient tension from affecting the photographic results. For harder, more elastic plastic film rolls, the tension can be precisely adjusted to a suitable level to prevent excessive tension from causing stretching, deformation, or damage to the roll material, ensuring that the roll material passes smoothly through the arc-shaped guide platform 5 under appropriate tension, thus guaranteeing the accuracy and quality of the photographs. Moreover, since the tensioning roller 15 is connected to the transmission wheel 81, its tension adjustment can work in coordination with the transmission system of the entire polishing platform. The tension can be dynamically adjusted according to factors such as the conveying speed of the roll and the speed of the drive motor 41, so that the roll is always in the best tension state, better adapting to various changes in the production process and improving the equipment's compatibility and adaptability to different rolls.
