Abstract
Description
Technical Field
[0001] This invention relates to visual inspection, specifically to a visual inspection device and method based on integrated ceiling production and processing. Background Technology
[0002] Visual inspection is a non-contact inspection technology based on machine vision. It utilizes industrial cameras, light sources, image acquisition and processing systems, and various sensors (such as photoelectric sensors and position sensors) to automatically collect, analyze, and determine the appearance, size, defects, and other features of an object being inspected. Its core method involves online real-time acquisition of image information of the object being inspected. The principle is that sensors accurately detect the object's position and location, triggering the industrial camera to start acquisition. The industrial camera converts the optical image of the object into a digital signal. The image processing system then filters, enhances, and segments the digital signal to extract the object's feature parameters. These parameters are compared with preset standard parameters to automatically determine whether the object is qualified.
[0003] Integrated ceilings, as an important component of prefabricated building decoration, boast advantages such as strong modularity, convenient installation, aesthetics, and durability, and are widely used in the interior decoration of residential, commercial, and public buildings. With expanding market demand and the implementation of national standards, the industry's requirements for the surface quality, dimensional accuracy, and appearance consistency of ceiling panels are constantly increasing. During processes such as stamping, laminating, spraying, and cutting, ceiling panels (such as aluminum composite panels, laminated panels, and honeycomb panels) are prone to defects such as surface scratches, dents, color differences, paint peeling, dimensional deviations, and edge warping, directly affecting product appearance and assembly precision. Therefore, there is an urgent need to introduce automated visual inspection equipment to automatically and online judge the surface defects, dimensional deviations, and appearance defects of integrated ceiling panels, replacing traditional manual visual inspection methods. This would unify inspection standards, improve inspection accuracy and production efficiency, reduce the risk of human error and missed inspections, and meet the quality control needs of mass production. However, existing visual inspection equipment has the following shortcomings in actual use:
[0004] In existing visual inspection equipment, industrial cameras and ring light sources mostly adopt a fixed installation structure. Once the installation height is set, it cannot be adaptively mechanically adjusted according to the different thicknesses of ceiling panels. In actual production, when dealing with thicker ceiling panels, the imaging distance between the lens and the panel surface is too small, easily causing interference problems such as specular reflection on glossy materials and local strong light spots. On the other hand, for thinner ceiling panels, the imaging distance is too large, resulting in blurred images and lens defocusing. This makes it difficult to clearly image and reliably identify minor defects such as tiny scratches, pinholes, local color differences, and coating edge lifting on the panel surface. The equipment has weak compatibility and adaptability to various thicknesses of panels, resulting in poor inspection versatility. At the same time, existing ring light sources are mostly installed at a fixed pitch angle, which cannot adaptively adjust the pitch and deflection according to the width and thickness of the ceiling panel. For large and long panels, the illumination angle of the light source cannot be extended, resulting in insufficient depth of illumination coverage and inaccurate illumination depth on the front and back of the panel. The ends and edges are prone to forming dark areas and shadow blind spots. For small-sized and narrow-width panels, the light source cannot be focused, resulting in ineffective light diffusion and waste. It is also very easy to form scattered reflective spots on the panel surface, which greatly reduces the imaging contrast of panel texture, edge chipping, and minor defects, directly affecting the accuracy of defect identification. The overall visual inspection stability and reliability are insufficient. In addition, conventional visual inspection equipment generally lacks mechanical automatic cleaning mechanisms. The lens and ring light source mask can only be maintained by manual periodic shutdowns for wiping. There is a lot of dust and aluminum shavings floating in the ceiling panel processing site. The workshop environment is humid and oil mist, which easily adheres to and accumulates on the camera lens and light source surface. Long-term accumulation will cause the lens transmittance to decrease and the image to become hazy and foggy. Combined with dust spots and stray light interference, it further aggravates the problems of missed detection and false detection. Manual wiping not only consumes time and increases maintenance labor costs, but also requires frequent shutdowns, interrupting the continuous operation rhythm of the production line and seriously affecting the overall production efficiency.
[0005] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention
[0006] The purpose of this invention is to provide a visual inspection device and method based on integrated ceiling production and processing to solve the problems mentioned in the background.

The system includes a centering plate, and a light source camera adaptive adjustment assembly is jointly provided between the opposing surfaces of the two centering plates, the interior of the mounting slide, and the interior of the main frame. Support plates are vertically fixed to the left and right sides of the bottom of the industrial camera. A micro motor is fixedly installed at the front end of the left support plate, and the output end of the micro motor extends horizontally backward and is fixedly connected to a threaded rod.

[0008] Preferably, a slider is fixedly installed on the back of the industrial camera by bolts, and the slider slides and engages with the front groove of the mounting slide block for limiting the movement.

[0009] Preferably, the rear end of the threaded rod horizontally penetrates the left support plate and extends to its inner side, and the threaded rod and the penetration position of the left support plate are rotatably connected by a bearing. The left side of the movable plate is integrally formed with a protrusion, which is sleeved and threadedly connected to the outside of the threaded rod. The right side of the movable plate slides against the side of the right support plate, and the two form a limiting sliding connection structure.
[0010] Preferably, the adaptive adjustment component of the light source camera includes a movable plate, which is rotatably hinged to the top of the inner wall of the frame body via a hinge shaft. A first torsion spring is fitted onto the hinge shaft end of the movable plate and the frame body, which provides the movable plate with a return spring force. A connecting plate is rotatably hinged to the bottom of one end of the movable plate via a hinge member. A floating pressure roller is rotatably connected to the bottom of the connecting plate via a rotating shaft, and the bottom of the floating pressure roller corresponds to the conveying surface of the conveyor belt assembly. A connecting plate is rotatably hinged to the bottom of the other end of the movable plate via a hinge member. A linkage plate is fixedly connected to the top of the opposite surfaces of the two centering plates via bolts. The tops of the two linkage plates are rotatably hinged to the outer surface of the ring light source via a hinge telescopic plate. The slider has symmetrically opened mounting slots on the left and right sides inside. A limit block is slidably connected in each mounting slot. A first spring is fixedly installed between the opposite ends of the two limit blocks and the inner wall of the corresponding mounting slot. The inner wall of the sliding groove on the front of the mounting slide has limit grooves that are adapted to the limit blocks at equal intervals along its length direction.
[0011] Preferably, the bottom of the connecting plate and the top of the slider are fixedly connected by bolts, so that the movable plate and the slider are linked and cooperate. The linkage plate is set in an "L" shape, with its horizontal section fixedly connected to the centering plate and its vertical section hinged to the hinged telescopic plate.
[0012] Preferably, the opposite ends of the two limiting blocks penetrate the sidewall of the slider and extend out of its outer surface, and the ends of the limiting blocks extending out of the slider are engaged with the limiting groove to achieve the positioning of the slider on the mounting slide.
[0013] Preferably, the air-blowing brush cleaning assembly includes two fixed plates, which are slidably disposed within sliding grooves on the left and right sides of a movable plate. Each fixed plate has a guide rod horizontally fixedly connected to its front end. A second spring is fixedly installed between the rear end of each fixed plate and the inner wall of the corresponding sliding groove, providing a restoring force for the fixed plate. Driven rollers are rotatably connected to the sides of each fixed plate at equal intervals along its height direction via rotating shafts. A lead screw is rotatably connected to one side of each fixed plate inside the movable plate via a bearing. The lower end of the lead screw... A driven roller is sleeved and fixed on the side, and the driven roller rolls in contact with the outer side of the corresponding driving roller. A threaded sleeve is sleeved and threadedly connected to the outer side of the upper end of the lead screw. Inclined grooves are opened on both the left and right sides of the front of the mounting slide, and the inclined grooves correspond one-to-one with the guide rods. Driven half gears are sleeved and fixed on the outer sides of both ends of the rotating rod. A second torsion spring is sleeved at the rotation connection position between the rotating rod and the moving plate. The second torsion spring is used to provide the return spring force of the rotating rod. Racks are fixedly connected to the lower side of the two opposing surfaces of the support plates by bolts, and the racks correspond one-to-one with the driven half gears.
[0014] Preferably, the end of the guide rod away from the fixed plate extends into the interior of the corresponding inclined groove, and the end of the guide rod slides and fits against the inclined surface of the inclined groove. The multiple active rollers are all tightly fitted with the outer side of the corresponding driven rollers to form a linkage transmission structure. The top end of the threaded sleeve is fixedly connected to the bottom of the cleaning brush to realize the vertical height adjustment of the cleaning brush.
[0015] Preferably, the teeth on the rack are arranged in multiple sets of intermittent and uniformly, and the rack is meshed with the driven half gear at the corresponding position. When the moving plate moves, the rotating rod is driven to rotate intermittently through the meshing of the rack and the driven half gear.
[0016] Preferably, a method for using a visual inspection device in integrated ceiling manufacturing includes the following steps:
[0017] S1: The ceiling panels are conveyed to the centering plates via the conveyor belt assembly. Then, the centering plates are centered and corrected by the first cylinder to ensure that the panels are accurately located in the center of the industrial camera's field of view. At the same time, the centering plates drive the linkage plate and the hinge telescopic plate to adjust the angle of the ring light source. After that, the ceiling panels lift the floating pressure rollers, and through the transmission of the connecting plate and the movable plate, the industrial camera is pushed to move down adaptively according to the thickness of the panels to ensure clear imaging.
[0018] S2: A micro motor drives a threaded rod to move the moving plate back and forth. The cleaning brush is attached to the industrial camera and ring light source to wipe away dust. At the same time, an external air supply is delivered to the nozzle through an air storage pipe and hose to blow away dust in a directional manner. The dual cleaning avoids impurities from interfering with the imaging quality and meets the cleanliness requirements of visual inspection.
[0019] S3: When the moving plate moves, the driven half gear rotates intermittently along the intermittent rack, driving the nozzle to swing and blow, eliminating cleaning dead angles. When the industrial camera moves down, the guide rod moves along the inclined groove, driving the active roller and lead screw to operate, adaptively adjusting the contact force of the cleaning brush, and improving cleaning adaptability.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. This invention enables precise centering and adaptive imaging adjustment of ceiling panels, solving problems such as panel misalignment, inaccurate imaging, and insufficient clarity. After the conveyor belt assembly transports the panels between the centering plates, the first cylinder drives the centering plate to center and correct the panel, ensuring that the panel is precisely located in the center of the industrial camera's field of view. The centering plate's movement synchronously drives the linkage plate, causing the hinged telescopic plate to push the ring light source to adaptively adjust its angle, adapting to the optical path requirements of different panel sizes. At the same time, the panel lifts the floating pressure roller, which, through lever transmission, drives the industrial camera to move downwards with the panel thickness, ensuring imaging clarity and detection stability.
[0022] 2. This invention adopts a combined air blowing and brushing cleaning method to solve the problem of incomplete dust removal by single cleaning; a micro motor drives a threaded rod to move a moving plate, so that the cleaning brush can fit against the lens and ring light source to brush away dust; at the same time, an external air source is delivered to the nozzle through a pipeline to spray airflow onto the lens and light source to blow away dust. The dual purification can effectively remove impurities, ensure imaging quality, and extend the service life of components.
[0023] 3. This invention optimizes the air blowing structure, expands the cleaning coverage area, and eliminates dead corners; when the moving plate moves, it drives the driven half gear to translate along the rack of the intermittent tooth block, and with the reset of the torsion spring, the driven half gear rotates intermittently, driving the nozzle to swing back and forth to blow air, ensuring that the lens and light source surface are thoroughly cleaned and improving the dust removal effect.
[0024] 4. This invention can adaptively adjust the adhesion force of the cleaning brush to meet the testing needs of different specifications of boards; when the industrial camera moves down with the thickness of the board, the guide rod moves down along the inclined groove and generates lateral displacement, which drives the active roller, driven roller and lead screw to rotate, and drives the cleaning brush to move up and down through the threaded sleeve, adjusting the cleaning force and avoiding incomplete cleaning or damage to parts.

Detailed Implementation
[0036] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.
[0037] Please see Figures 1-10This invention provides a technical solution: a visual inspection device and method based on integrated ceiling production and processing, including a conveyor belt assembly 1, a frame body 2 fixed on the upper surface of the conveyor belt assembly 1, a second cylinder installed on the left side of the upper surface of the conveyor belt assembly 1, and a rejection plate 3 fixed to the telescopic end of the second cylinder, an inclined plate and a collection box 4 respectively installed on the right side of the upper surface of the conveyor belt assembly 1, a mounting slide 5 fixed on the top of the inner wall of the frame body 2, and an industrial camera 6 arranged on the front of the mounting slide 5; it also includes a ring light source 7, which is rotatably sleeved on the bottom outer side of the industrial camera 6 via a rotating shaft, first cylinders are fixedly installed on the lower left and right sides of the inner wall of the frame body 2 by bolts, and the telescopic ends of the two first cylinders are arranged opposite each other and fixedly connected to a centering plate 9, support plates 11 are vertically fixed on the left and right sides of the bottom of the industrial camera 6, and a micro motor 12 is fixedly installed at the front end of the left support plate 11, the output end of the micro motor 12 extends horizontally backward and is fixedly connected to a threaded rod 13, and a moving plate 14 is horizontally arranged between the two support plates 11, and the moving plate 14... A cleaning brush 15 for cleaning the lens of an industrial camera 6 is fixedly connected to the upper surface. The rear end of the threaded rod 13 horizontally passes through the left support plate 11 and extends to its inner side. The threaded rod 13 and the left support plate 11 are rotatably connected by a bearing at the through-point. A protrusion is integrally formed on the left side of the movable plate 14. The protrusion is sleeved and threadedly connected to the outside of the threaded rod 13. The right side of the movable plate 14 slides against the side of the right support plate 11, and the two form a limiting sliding connection structure. A rotating rod 1 is horizontally rotatably connected to the front of the movable plate 14. 7. Spray nozzles 16 are evenly spaced and fixed on the outer side of the rotating rod 17 along its length. A slider 8 is fixedly installed on the back of the industrial camera 6 by bolts. The slider 8 slides and engages with the sliding groove on the front of the mounting slide block 5. An air storage pipe 18 is horizontally fixedly connected to the bottom of the moving plate 14. The top of the air storage pipe 18 is connected to the corresponding spray nozzles 16 one by one through multiple evenly distributed hoses 19. An air inlet pipe is fixedly connected to the left end of the air storage pipe 18. The end of the air inlet pipe away from the air storage pipe 18 is sealed to the external air supply source.
[0038] In one embodiment of the present invention, before starting the equipment, the status of each component is checked: ensuring that the conveyor belt assembly 1 operates smoothly, and that the industrial camera 6, ring light source 7, cylinders, micro motors 12, and external air supply are working properly; in the cleaning mechanism, the cleaning brush 15 maintains a reasonable fit with the lens surface of the industrial camera 6 and the surface of the ring light source 7, the nozzle 16 is precisely aligned with the cleaning area, and there is no air leakage in the air storage pipe 18 and hose 19. Then, the operator places the integrated ceiling panel to be inspected stably on the left end of the conveyor belt assembly 1 and starts the conveyor belt assembly 1. The workpiece is conveyed to the right at a uniform speed with the conveyor belt, and the centering mechanism adjusts the workpiece to the center position of the conveyor belt assembly 1 to achieve the centering and positioning of the workpiece, ensuring that the workpiece is properly positioned during subsequent visual inspection. The center is aligned with the shooting center of the industrial camera 6 to avoid missed or false detections due to workpiece offset. Then, the height and angle of the industrial camera 6 and the ring light source 7 can be adjusted according to different specifications of ceiling panels through the adaptive adjustment component of the light source camera, ensuring uniform light coverage of the workpiece and stable shooting distance, effectively avoiding missed or false detections, and greatly improving detection accuracy and equipment adaptability. Then, the micro motor 12 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the moving plate 14 to move back and forth in a linear reciprocating motion, which in turn drives the cleaning brush 15 to slide and wipe along the lens surface of the industrial camera 6 and the surface of the ring light source 7, realizing contact brushing dust removal. At the same time, the external air supply source supplies air into the air storage pipe 18 through the air inlet pipe, and the airflow is then passed through multi-component flow. The hose 19 delivers air to each nozzle 16, which then sprays airflow directionally towards the mirror surface of the industrial camera 6 and the surface of the ring light source 7, completing non-contact air blowing dust removal. This composite cleaning method, which first blows away loose dust and then gently brushes away stubborn stains, effectively cleans the lens and light source surfaces, preventing dust, oil mist, and lint from interfering with image quality. After the workpiece is aligned and its height is adaptively adjusted, it moves with the conveyor belt assembly 1 to directly below the industrial camera 6. At this point, the industrial camera 6 activates and, with the auxiliary illumination of the ring light source 7, captures an all-around image of the workpiece's surface appearance. The industrial camera 6 transmits the captured image information to the equipment control system in real time, and the control system uses preset images... The recognition algorithm analyzes and processes the image, compares it with the appearance parameters of the standard workpiece, and determines whether the workpiece has defects such as scratches, dents, color differences, and edge damage. It also records the location and size of the defects. When the equipment control system determines that the workpiece is a defective product, it will simultaneously trigger the conveyor belt assembly 1. The second cylinder on the left side will start, and the telescopic end of the second cylinder will quickly extend, pushing the rejection plate 3 fixed at its end towards the defective workpiece. The defective ceiling panel will be smoothly pushed onto the inclined plate on the right side of the conveyor belt assembly 1. The defective panel will slide smoothly down the inclined plate into the preset collection box 4 under its own weight, completing the rapid rejection and centralized collection of defective products, preventing defective products from being mixed into finished products, and at the same time not affecting the normal conveying and inspection of qualified workpieces.
[0039] An adaptive adjustment assembly for the light source camera is provided between the opposing surfaces of the two centering plates 9, the interior of the mounting slide 5, and the interior of the frame body 2. This assembly includes a movable plate 1004, which is rotatably hinged to the top of the inner wall of the frame body 2 via a hinge shaft. A first torsion spring is fitted onto the hinge shaft end of the movable plate 1004 and the frame body 2, providing a return spring force for the movable plate 1004. A connecting plate 1002 is rotatably hinged to the bottom of one end of the movable plate 1004 via a hinge. A floating pressure roller 1001 is rotatably connected to the bottom of the connecting plate 1002 via a rotating shaft, and the bottom of the floating pressure roller 1001 corresponds to the conveying surface of the conveyor belt assembly 1. A connecting plate 1006 is rotatably hinged to the bottom of the other end of the movable plate 1004 via a hinge. Linkage plates 1003 are bolted to the top of the opposing surfaces of the two centering plates 9, and the tops of the two linkage plates 1003 are connected to the annular light source 7. The outer surfaces of the slide block 8 are all hinged together by a hinged telescopic plate 1005. The bottom of the connecting plate 1006 is fixedly connected to the top of the slider 8 by bolts, so that the movable plate 1004 and the slider 8 are linked and cooperate. The linkage plate 1003 is set in an "L" shape. Its horizontal section is fixedly connected to the centering plate 9, and its vertical section is hinged to the hinged telescopic plate 1005. The left and right sides of the slider 8 are symmetrically provided with mounting grooves. Each mounting groove is slidably connected with a limit block 1007. The opposite ends of the two limit blocks 1007 are fixedly installed between the inner wall of the corresponding mounting groove. The inner wall of the sliding groove on the front of the mounting slide 5 is provided with limit grooves 1009 that are adapted to the limit blocks 1007 at equal intervals along its length. The opposite ends of the two limit blocks 1007 penetrate the side wall of the slider 8 and extend out of its outer surface. The end of the limit block 1007 extending out of the slider 8 is engaged with the limit groove 1009 to realize the positioning of the slider 8 on the mounting slide 5.
[0040] In one embodiment of the present invention, the ceiling panels are conveyed to the space between two centering plates 9 via the conveyor belt assembly 1. At this time, two first cylinders drive the two centering plates 9 to move relative to each other, centering and correcting the conveyed ceiling panels to prevent deviation or skew during transport. This ensures that each ceiling panel is precisely positioned at the center of the field of view of the industrial camera 6, achieving no missed shots at the panel edges and consistent image framing. Simultaneously, the two centering plates 9, along with the centering action, drive the two sets of linkage plates 1003 to move synchronously relative to each other, causing the hinged telescopic plate 1005 to rotate from an inclined position to a vertical position, thereby pushing the ring light source 7 upwards and driving the ring light source... 7. Angle rotation adaptive adjustment is generated to adapt to the light path illumination requirements of different sized panels; at the same time, the ceiling panels delivered to the position push the floating pressure roller 1001 upward, driving the connecting plate 1002 to vertically push the movable plate 1004, and the movable plate 1004 rotates around the hinge fulcrum; with the help of the lever transmission principle, the connecting plate 1006 on the other side of the movable plate 1004 is driven to move downward, thereby pushing the slider 8 and the industrial camera 6 to move downward as a whole; the greater the thickness of the panel, the greater the lifting stroke of the floating pressure roller 1001, and the greater the downward movement of the industrial camera 6, automatically adapting to the close-range imaging conditions of thick panels, ensuring imaging clarity and detection stability.
[0041] An air-blowing brush cleaning assembly is provided between the interior of the movable plate 14, the side of the support plate 11, and the outer side of the rotating rod 17. The air-blowing brush cleaning assembly includes two fixed plates 2004, which are slidably disposed within sliding grooves on the left and right sides of the interior of the movable plate 14. Guide rods 2002 are horizontally fixedly connected to the front ends of both fixed plates 2004.

Multiple driving rollers 2005 are tightly fitted with the outer side of the corresponding driven roller 2006, forming a linkage transmission structure. The top end of the threaded sleeve 2001 is fixedly connected to the bottom of the cleaning brush 15, realizing the vertical height adjustment of the cleaning brush 15. Driven half gears 2009 are sleeved and fixed on the outer side of both ends of the rotating rod 17, and the rotation... A second torsion spring is fitted at the rotatable connection position between rod 17 and moving plate 14. This second torsion spring is used to provide the restoring force of rotating rod 17. Racks 2010 are fixedly connected to the lower side of the opposite surfaces of the two support plates 11 by bolts. The racks 2010 correspond one-to-one with the driven half gears 2009. The teeth on the racks 2010 are arranged in multiple sets of intermittent and uniformly. The racks 2010 are meshed with the driven half gears 2009 at the corresponding positions. When the moving plate 14 moves, the rotating rod 17 is driven to rotate intermittently through the meshing of the racks 2010 and the driven half gears 2009.
[0042] In one embodiment of the present invention, during the back-and-forth movement of the movable plate 14, the driven half gear 2009 is driven to perform a horizontal translational movement along the rack 2010; and because the teeth on the rack 2010 adopt a multi-set intermittent arrangement structure, combined with the reset action of the second torsion spring, the driven half gear 2009 generates intermittent rotation, thereby driving the rotating rod 17 and multiple nozzles 16 to swing back and forth, realizing the swing-type air blowing cleaning of the mirror surface of the industrial camera 6 and the surface of the ring light source 7, expanding the airflow cleaning coverage area, and eliminating cleaning To improve dust and impurity removal in blind spots, when the industrial camera 6 moves downward, the guide rod 2002 moves downward along the inclined groove 2003 and is squeezed by the inclined surface of the inclined groove 2003, resulting in lateral displacement. This drives the active rollers 2005 on the fixed plate 2004 to drive the driven rollers 2006 to rotate synchronously, which in turn drives the lead screw 2007 to rotate. The threaded sleeve 2001 drives the cleaning brush 15 to move upward, so that the contact force and wiping intensity of the cleaning brush 15 can be adaptively adjusted according to different specifications of ceiling panels.
[0043] A method for using a visual inspection device in integrated ceiling manufacturing includes the following steps:
[0044] S1: The ceiling panel is conveyed to the centering plate 9 via the conveyor belt assembly 1. Then, the centering plate 9 is driven by the first cylinder to center and correct the deviation, ensuring that the panel is accurately located in the field of view of the industrial camera 6. At the same time, the centering plate 9 drives the linkage plate 1003 and the hinge telescopic plate 1005 to adjust the angle of the ring light source 7. Then, the ceiling panel lifts the floating pressure roller 1001, and through the transmission of the connecting plate 1002 and the movable plate 1004, it pushes the industrial camera 6 to move down adaptively according to the thickness of the panel, ensuring clear imaging.
[0045] S2: The micro motor 12 drives the threaded rod 13 to move the moving plate 14 back and forth. The cleaning brush 15 is attached to the industrial camera 6 and the ring light source 7 to wipe away dust. At the same time, the external air supply is delivered to the nozzle 16 through the air storage pipe 18 and the hose 19 to blow away the dust in a directional manner. The dual cleaning avoids impurities from interfering with the imaging quality and meets the cleanliness requirements of visual inspection.
[0046] S3: When the moving plate 14 moves, the driven half gear 2009 rotates intermittently along the intermittent rack 2010, driving the nozzle 16 to swing and blow, eliminating cleaning dead angles. When the industrial camera 6 moves down, the guide rod 2002 moves along the inclined groove 2003, driving the active roller 2005 and the lead screw 2007 to rotate, adaptively adjusting the contact force of the cleaning brush 15, and improving cleaning adaptability.
