Description

Technical Field

[0001] This invention relates to the field of printing inspection technology, and in particular to a wide-format automatic registration visual inspection system. Background Technology

[0002] Digital printing presses are devices that integrate modern digital technology with traditional printing processes, and are widely used in various fields such as commerce, advertising, and publishing. With their high efficiency, flexibility, and environmental friendliness, digital printing presses demonstrate significant advantages in multiple sectors.

[0003] In the printing process of digital printing presses, registration deviations of various colors on printed products are unavoidable. The human eye cannot keep up with the production speed of the machine and cannot accurately judge the registration deviation value. In order to avoid large-scale quality accidents, an online vision inspection system is needed to monitor the registration deviation in real time and feed it back to the printing system. Therefore, a wide-format automatic registration vision inspection system is urgently needed to solve the above-mentioned technical problems.

[0004] Existing visual inspection devices have several shortcomings in practical applications. First, many devices lack flexibility, failing to precisely adjust the angle and position of the camera and light source according to actual needs, thus limiting their applicability and making it difficult to meet the inspection requirements of printed products with different angles and widths. Second, during prolonged operation, dust and impurities easily accumulate on the camera lens, affecting image clarity and reducing inspection accuracy. However, most current devices lack effective lens cleaning functions, requiring manual intervention, increasing maintenance costs and downtime. Furthermore, the printing environment often includes odors from ink evaporation and fine particulate matter, which not only threaten the long-term stable operation of the equipment but may also harm the health of operators. Existing devices often neglect functions such as heat dissipation, dust collection, and air purification, further limiting their application effectiveness in complex environments. Therefore, developing a wide-format automatic registration visual inspection device capable of real-time monitoring, high-precision detection, automatic cleaning, and efficient heat dissipation and air purification is of significant practical importance. This device should possess flexible angle and position adjustment capabilities to adapt to the needs of different working scenarios; simultaneously, it should integrate protection, cleaning, and dust-collecting heat dissipation mechanisms to ensure the equipment maintains efficient and stable operation in complex environments, thereby effectively solving the problems existing in current technologies and improving the quality and production efficiency of printed products. Summary of the Invention

[0005] This invention discloses a wide-format automatic registration visual inspection system. By incorporating a visual inspection mechanism, the system can be pre-installed at a suitable location near a digital printing press before operation. During operation, a camera, in conjunction with a light source, photographs the printed products passing over the traction rollers of the digital printing press. The images are transmitted in real-time to an external display and control terminal. The visual inspection software in the display and control terminal analyzes and compares the acquired images, then transmits the deviation data to the digital printing press's software. The printing software then adjusts the registration deviation in real-time, achieving the effect and purpose of real-time monitoring of the registration deviation of printed products. Furthermore, by incorporating angle adjustment, position adjustment, protective mechanisms, lens cleaning mechanisms, and dust collection and heat dissipation mechanisms, the system allows for flexible adjustment of the camera and light source angles and positions during operation to meet the needs of different working scenarios. It also protects the camera and light source, and collects, filters, and purifies dust and ink odors. In summary, this system solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention provides a wide-width automatic alignment visual inspection system, comprising a first slide rail, a first sliding sleeve being slidably mounted on the outside of the first slide rail, a driving device being externally connected to the first sliding sleeve, and a first sliding base being fixedly connected to the top of the first sliding sleeve. An angle adjustment mechanism is located on top of the first slide block; A visual inspection mechanism includes a mounting base, a second slide rail, a second slide block, a camera, a connecting base, and a light source. The bottom of the mounting base is connected to an angle adjustment mechanism. The second slide rail is fixedly mounted on the top of the mounting base. The bottom of the second slide block is slidably connected to the second slide rail via a sliding connector. The camera is fixedly mounted on one side of the second slide block and is externally connected to a display control terminal. The connecting base is fixedly mounted on the top of the mounting base and near one edge of the mounting base. A through slot is provided inside the connecting base. The light source is annular and is fixedly mounted on the side of the connecting base away from the camera. A position adjustment mechanism is located on top of the mounting base and connected to the second slide. A protective mechanism is located on top of the mounting base and outside the camera and light source; A lens cleaning mechanism, which is located inside the protective mechanism and matches the position of the camera; A dust-collecting heat dissipation mechanism is located on top of the protective mechanism.

[0007] Furthermore, the inner ring of the light source matches the positional dimensions of the through slot, and the positional dimensions of the inner ring of the light source and the through slot match the positional dimensions of the camera.

[0008] Furthermore, the angle adjustment mechanism includes a first hinge assembly, a hinge post, a second hinge assembly, a hydraulic cylinder, and a third hinge assembly. Two sets of the first hinge assembly are provided, both sets being fixedly installed on the top of the first slide block, and both sets being close to the light source. Two hinge posts are provided, with their bottom ends respectively hinged to the two sets of first hinge assemblies. The bottom end of the hydraulic cylinder intersects with the top of the first slide block through the second hinge assembly, which is located away from the light source. The top of the hydraulic cylinder is hinged to the top of the first slide block through the third hinge assembly.

[0009] Furthermore, the first hinge assembly and the second hinge assembly are both welded to the top of the first slide, and the third hinge assembly is welded to the bottom of the mounting base.

[0010] Furthermore, the position adjustment mechanism includes a fixing block and a cylinder. The fixing block is fixedly installed on the top of the mounting base and is away from the light source. The cylinder is fixedly installed on one side of the fixing block, and the retracted end of the cylinder is connected to one side of the second slide.

[0011] Furthermore, the protective mechanism includes an extension plate and a protective cover. There are two extension plates, which are fixedly connected to the front and rear sides of the mounting base, respectively. The bottom of the protective cover is fixedly connected to the top of the two extension plates. The protective cover has an open design on the side closer to the light source, and multiple through ventilation holes are provided on the outer side of the protective cover.

[0012] Furthermore, the lens cleaning mechanism includes a brake motor, a rotating shaft, and a cleaning plate. The brake motor is fixedly installed inside the protective cover via a connecting column. One end of the rotating shaft is connected to the output end of the brake motor. The cleaning plate is fixedly fitted onto the outside of the rotating shaft. The cleaning plate has a brush section on the side near the brake motor, and the cleaning plate is located above the camera.

[0013] Furthermore, the bristles of the brush head are made of carbon fiber material.

[0014] Furthermore, the dust-collecting heat dissipation mechanism includes an exhaust fan and a dust collection box. Both the exhaust fan and the dust collection box are fixedly installed on the top of the protective cover. The exhaust end of the exhaust fan is connected to one side of the dust collection box, and the other side of the dust collection box is connected to two ducts. The bottom ends of the two ducts extend through the top of the protective cover into its interior. The bottom ends of the ducts are connected to a dust collection cover, which is angled towards the camera and the light source. The dust collection box is equipped with a filter screen plate and an activated carbon filter plate.

[0015] Furthermore, a door is hinged to one side of the dust collection box, and the door is sealed to the dust collection box when closed.

[0016] The present invention has the following advantages over the prior art: 1. This technical solution incorporates a visual inspection mechanism, allowing the device to be installed at a suitable location near the digital printing press before operation. During operation, a camera, in conjunction with a light source, captures images of the printed products passing over the traction rollers of the digital printing press. These images are transmitted in real-time to an external display and control terminal. The visual inspection software in the display and control terminal analyzes and compares the captured images, then transmits the deviation data to the digital printing press's software. The printing software then adjusts the registration deviation in real-time, achieving the effect and purpose of real-time monitoring of the registration deviation of the printed products. 2. This technical solution is equipped with an angle adjustment mechanism and a position adjustment mechanism, which allows the hydraulic cylinder to be activated as needed during operation. The hydraulic cylinder works in conjunction with the second hinge assembly, the third hinge assembly, the first hinge assembly, and the hinge column to adjust the angle of the mounting base, thereby synchronously adjusting the angles of the camera and the light source. This allows the camera and the light source to work together to meet different angle requirements. 3. This technical solution incorporates a protective mechanism, a lens cleaning mechanism, and a dust-collecting heat dissipation mechanism. During operation, the protective cover effectively protects the camera and light source. Furthermore, if, after a period of operation, a large amount of dust and impurities accumulate on the camera lens, affecting image clarity, the camera position can be adjusted so that the lens is below the cleaning plate. At this point, the brake motor is activated, causing the cleaning plate to rotate. This rotation, combined with its brush bristles, automatically cleans the camera lens, removing accumulated dust and impurities, effectively ensuring the camera has sufficient image quality. To improve image clarity, the exhaust fan can be activated during the above process. The exhaust fan, working in conjunction with the dust collection box and duct, generates suction at the dust collection hood. This not only effectively circulates air inside the protective cover through its opening and multiple ventilation holes, achieving heat dissipation and cooling for the camera and light source, but also effectively draws the cleaned dust and impurities into the dust collection box for centralized collection by the filter plate. Simultaneously, the activated carbon filter plate effectively adsorbs and purifies the ink odor in the extracted air, thereby effectively reducing health hazards to nearby workers – a multi-benefit approach.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] This invention discloses a wide-format automatic registration visual inspection system, which integrates modules such as an angle adjustment mechanism, a position adjustment mechanism, a protective mechanism, a lens cleaning mechanism, and a dust collection and heat dissipation mechanism to achieve efficient detection and real-time adjustment of registration deviations in digital printing press products. The following description, in conjunction with the appendix... Figure 1 To be continued Figure 8 The specific embodiments of the present invention will be described in detail below.

[0023] The core structure of this device includes a first slide rail 1, a first sliding sleeve 2, a first sliding base 3, an angle adjustment mechanism 4, a vision inspection mechanism 5, a position adjustment mechanism 6, a protective mechanism 7, a lens cleaning mechanism 8, and a dust collection and heat dissipation mechanism 9. These components together constitute a complete wide-format automatic registration vision inspection system. In practical applications, this device can be installed in a suitable location near a digital printing press, such as near the traction roller, to achieve real-time monitoring and deviation adjustment of printed products.

[0024] After the S1 device is installed, the first sliding sleeve 2 needs to be slidably fitted outside the first slide rail 1, and the first sliding sleeve 2 is controlled by an external drive device to slide and adjust horizontally along the first slide rail 1. The top of the first sliding sleeve 2 is fixedly connected to the first slide block 3, which provides a stable installation base for the subsequent angle adjustment mechanism 4 and other components. The design of the first slide rail 1 allows the entire device to move flexibly in the horizontal direction, thereby adapting to the inspection needs of printed products of different widths. In actual operation, the drive device can control the sliding position of the first sliding sleeve 2 according to the preset program or manual instructions to ensure that the camera 504 can accurately align with the inspection area on the printed product.

[0025] The S2 angle adjustment mechanism 4 is located on top of the first slide block 3 and is used to adjust the working angles of the camera 504 and the light source 506. The angle adjustment mechanism 4 includes a first hinge assembly 401, a hinge column 402, a second hinge assembly 403, a hydraulic cylinder 404, and a third hinge assembly 405. Two sets of the first hinge assembly 401 are fixedly installed on the top of the first slide block 3 near the light source 506. The bottom ends of the hinge column 402 are hinged to the two sets of the first hinge assembly 401 to form a stable support structure. The second hinge assembly 403 is fixedly installed on the top of the first slide block 3 away from the light source 506. The bottom end of the hydraulic cylinder 404 is connected to the second hinge assembly 405. 03 is hinged to the first slide 3, and the top is welded to the bottom of the mounting base 501 through the third hinge assembly 405. By activating the hydraulic cylinder 404, the extension and retraction of the hydraulic cylinder 404 can cooperate with the hinge assembly and the hinge column 402 to drive the mounting base 501 and the camera 504 and the light source 506 on it to adjust their angles. This design allows the camera 504 and the light source 506 to adapt to different angle detection requirements, ensuring that the shooting angle is always in the best state. In actual operation, the user can input the required tilt angle through the control system, and the hydraulic cylinder 404 will accurately adjust the angle of the mounting base 501 according to the input signal, thereby meeting the needs of different working scenarios.

[0026] The S3 visual inspection mechanism 5 is the core inspection unit of this device. It includes a mounting base 501, a second slide rail 502, a second slide block 503, a camera 504, a connecting base 505, and a light source 506. The bottom of the mounting base 501 is connected to the angle adjustment mechanism 4, and the top is fixedly mounted with the second slide rail 502. The bottom of the second slide block 503 is slidably connected to the second slide rail 502 through a sliding connector, thereby realizing the horizontal position adjustment of the camera 504. The camera 504 is fixedly mounted on one side of the second slide block 503 and connected to an external display control terminal for capturing images of printed products. The connecting base 505 is fixedly mounted on the top of the mounting base 501 and near one edge, with a through slot 507 inside. The light source 506 is annular and fixedly mounted on... The inner ring of the connector 505, located away from the camera 504, matches the position and dimensions of the through groove 507 and the camera 504. During actual operation, the light source 506 emits uniform light, which shines through the through groove 507 onto the surface of the printed product. The camera 504 then takes a clear picture of the printed product. The captured image is transmitted in real time to the display control terminal, where the visual inspection software analyzes and compares the image data to extract the registration deviation data. This data is then transmitted to the printing software of the digital printing press. The printing software adjusts the registration deviation in real time based on the received data, thereby achieving precise monitoring and adjustment of the registration deviation of the printed product. This process not only improves inspection efficiency but also significantly enhances inspection accuracy.

[0027] The S4 position adjustment mechanism 6 is located on top of the mounting base 501 and connected to the second slide block 503. It is used to adjust the horizontal position of the camera 504 and the light source 506. The position adjustment mechanism 6 includes a fixing block 601 and a cylinder 602. The fixing block 601 is fixedly installed on the top of the mounting base 501 away from the light source 506. The cylinder 602 is fixedly installed on one side of the fixing block 601, and its telescopic end is connected to one side of the second slide block 503. When it is necessary to adjust the horizontal position of the camera 504 and the light source 506, the cylinder 602 is activated. The telescopic action of the cylinder 602 will drive the second slide block 503 to slide along the second slide rail 502, thereby achieving precise adjustment of the horizontal position. This design allows the camera 504 to flexibly cover the detection needs of different areas and ensure the comprehensiveness of the detection range.

[0028] The S5 protective mechanism 7 is located on top of the mounting base 501 and covers the exterior of the camera 504 and the light source 506. It is used to protect the equipment from the influence of the external environment. The protective mechanism 7 includes an extension plate 701 and a protective cover 702. There are two extension plates 701, which are fixedly connected to the front and rear sides of the mounting base 501 respectively. The bottom of the protective cover 702 is fixedly connected to the top of the extension plate 701. The side near the light source 506 is designed with an opening, and multiple through ventilation holes 703 are opened on the outside. The design of the protective cover 702 can not only effectively block external dust and ink particles to prevent them from contaminating the camera 504 and the light source 506, but also allow air circulation through the ventilation holes 703 to reduce the temperature of the equipment. In actual use, the opening design of the protective cover 702 allows light to enter smoothly, while the ventilation holes 703 ensure the circulation of internal air, thereby maintaining the normal operating temperature of the equipment.

[0029] The S6 lens cleaning mechanism 8 is located inside the protective mechanism 7 and matches the position of the camera 504. It is used to automatically clean the lens of the camera 504. The lens cleaning mechanism 8 includes a brake motor 801, a rotating shaft 802, and a cleaning plate 803. The brake motor 801 is fixedly installed inside the protective cover 702 via a connecting column 804. One end of the rotating shaft 802 is connected to the output end of the brake motor 801. The cleaning plate 803 is fixedly fitted outside the rotating shaft 802 and is located above the camera 504. The cleaning plate 803 has a brush part 805 on the side near the brake motor 801. The brush part 805 is made of carbon fiber material, which has good wear resistance and cleaning effect. When dust adheres to the surface of the camera 504 lens, the brake motor 801 is activated. The brake motor 801 drives the rotating shaft 802 to rotate, thereby driving the cleaning plate 803 to rotate. The brush part 805 of the cleaning plate 803 contacts the lens surface and removes dust, ensuring the sharpness of the camera 504. This automated cleaning function significantly reduces the need for manual intervention and improves the reliability and service life of the equipment.

[0030] The S7 dust-collecting heat dissipation mechanism 9 is located on top of the protective mechanism 7. It is used to dissipate heat and cool the camera 504 and light source 506, and to collect dust and impurities generated during the cleaning process. The dust-collecting heat dissipation mechanism 9 includes an exhaust fan 901, a dust collection box 902, a duct 903, a filter plate 905, and an activated carbon filter plate 906. The exhaust fan 901 is fixedly installed on the top of the protective cover 702; the dust collection box 902 is fixedly installed on the top of the protective cover 702 and connected to the exhaust fan 901; the duct 903 connects the dust collection box 902 and the dust cover 904, and is angled towards the camera 504 and light source 506; the filter plate 905 and the activated carbon filter plate 906 are activated. The moving card is installed inside the dust collection box 902 to intercept and filter dust and impurities and absorb ink odors; the box door 907 is hinged to one side of the dust collection box 902 and is sealed to the dust collection box 902 when closed, which facilitates cleaning and maintenance. In actual operation, after the exhaust fan 901 is started, the exhaust fan 901 generates negative pressure, which draws out the hot air in the protective cover 702 through the duct 903 and the dust collection cover 904. The drawn air is filtered by the filter screen plate 905 and the activated carbon filter plate 906 before being discharged, thereby realizing the functions of heat dissipation, dust collection and purification. This design not only effectively reduces the temperature of the equipment, but also reduces the impact of dust and odors on the staff.

[0031] In summary, the wide-format automatic registration visual inspection device proposed in this invention achieves efficient detection and real-time adjustment of registration deviations in printed products through the synergistic effect of various functional modules. In actual operation, the device can quickly respond to inspection needs, ensuring the accuracy of the inspection results. Furthermore, through the design of the angle adjustment mechanism 4 and the position adjustment mechanism 6, the camera 504 and the light source 506 can flexibly adjust their angles and positions to meet the needs of different working scenarios. The introduction of the protective mechanism 7, the lens cleaning mechanism 8, and the dust-collecting heat dissipation mechanism 9 further improves the reliability and service life of the equipment while reducing the physical harm to workers. This invention can be widely applied in the field of online visual inspection of digital printing presses, providing technical support for improving printing quality and production efficiency.
