Description

Technical Field

[0001] This invention relates to the field of visual intelligent detection technology for board defects, specifically to a visual intelligent detection device for board defects in cabinet processing. Background Technology

[0002] Currently, the cabinet board processing industry is developing rapidly. During the cutting, sanding, veneering, and edge banding processes of cabinet and decorative boards, surface defects such as scratches, dents, color differences, stains, burrs, cracks, and veneer delamination are easily generated. The surface quality of the boards directly determines the aesthetics and product grade of the finished cabinets. Therefore, board defect detection is an essential and crucial process in cabinet production. At present, most small and medium-sized board processing enterprises still rely on manual visual sampling for quality inspection. Manual inspection is greatly affected by personnel condition, inspection experience, and ambient lighting. Prolonged high-intensity observation can easily cause visual fatigue, resulting in low inspection efficiency and widespread missed or false detections. Inspection standards are difficult to unify, which is not conducive to achieving stable and high-precision screening of large batches of boards. Therefore, visual intelligent inspection equipment for board defects has emerged.

[0003] When sheet materials are transported at high speed, they are prone to deviation and skew, causing the shooting point to deviate from the preset benchmark and the imaging coordinates to become off. The system compares and analyzes the misaligned images, making it difficult to accurately match the standard sample parameters. Minor scratches, color differences, bumps and other defects are easily misjudged, significantly increasing the probability of missed or false detections. Ultimately, defective sheets will flow into the next process, resulting in a decrease in the product quality inspection pass rate. At the same time, the deviation in the shooting point will also lead to inaccurate defect positioning coordinates. Subsequent marking and sorting processes cannot accurately correspond to the defect location, affecting the quality control effect of the entire production line. The lack of a top limiting structure when the sheet materials enter the inspection area makes them prone to vertical jumping and surface undulation during operation. This will cause repeated changes in the imaging focal length, unstable image clarity, and difficulty in clearly capturing defects at the edges and indentations.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

The auxiliary frame is located around the conveyor frame near one end of the optical defect detection station.

[0008] Preferably, a number of ball bearings are installed on the mirror surfaces of the two sets of limiting plates, and an inclined short plate is installed at the end of the two sets of limiting plates away from the optical defect detection stage; the inclined short plate at the end of the two sets of limiting plates has an opening design inside the conveyor frame, and the opening is larger at the end away from the optical defect detection stage.

[0009] Preferably, four sets of sliding rods are installed on the top of the buffer plate. The four sets of sliding rods are evenly distributed in the buffer plate near the edge area. The four sets of sliding rods slide within the drive plate and are limited. Springs are sleeved on the surface of each of the four sets of sliding rods. The top of the springs is connected to the drive plate and the bottom of the springs is connected to the buffer plate.

[0010] Preferably, the two sets of pressure plates are symmetrically arranged on both sides of the movable frame, the bottom side plates of the two sets of pressure plates are inclined, and springs are sleeved on the surface of the limiting rods on both sides of the movable frame. One end of the spring is connected to the protrusion at the end of the limiting rod, and the other end of the spring is connected to the pressure plate.

[0011] Preferably, a spring is installed on the side of the adjusting plate near the limiting plate, and the other end of the spring is connected to the limiting plate. An inclined surface is provided on the side end of the extrusion block, and the inclined surface of the extrusion block abuts against the extrusion rod.

[0012] Preferably, the pressure stabilizing and limiting mechanism includes a sleeve rotatably connected to the bottom of the movable frame, a ring plate installed at the bottom of the sleeve, a miniature push rod installed inside the buffer plate, an extension rod installed at the extended end of the miniature push rod, a first oil tank installed at the top of the movable frame, a first piston rod slidingly limited inside the first oil tank, the top of the first piston rod being connected to a protruding plate on the surface of the extension rod, and a second oil tank installed at the top of the conveyor frame, a second piston rod slidingly limited inside the second oil tank, and the second piston rod being connected to the extrusion block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a limiting plate and an anti-deviation adjustment mechanism, can form elastic contact limiting constraints on both sides of the cabinet panels during the conveying process. This effectively solves the problems of easy deviation, skewing, and displacement of panels during high-speed conveying, ensuring that the panels remain in a centered and stable conveying state. It avoids problems such as camera shooting point deviation, image misalignment, and image shift caused by panel deviation and disorder. At the same time, the mechanism has adaptive characteristics, which can automatically adjust the contact limiting force according to changes in panel thickness. When the panel thickness increases, the elastic clamping force on the side of the panel is increased simultaneously, ensuring that cabinet panels of different thicknesses and specifications can obtain a stable and close limiting effect. It is suitable for switching production of multiple panel specifications. It will not cause side squeezing damage or scratches to the edge banding due to excessive clamping, nor will it cause panel shaking and deviation due to excessively loose limiting. While ensuring the accuracy of conveying and positioning, it effectively protects the appearance quality of the panel, achieving stable posture positioning of the panel throughout the conveying process, without the need for repeated manual calibration of the panel position. 2. This invention, by setting up a moving frame, a pressure plate, and a pressure-stabilizing and limiting mechanism, can form a stable elastic pressure and limiting constraint on the top of the board during the process of conveying the board into the detection area. This effectively improves the problems caused by conveying vibration, slight warping of the board, vertical jumping, board surface undulation, and unstable posture during traditional board conveying. It ensures that the board to be inspected remains flat and in a stable conveying state throughout the visual acquisition process, with a constant board height. By stabilizing the conveying posture of the board, it effectively avoids frequent camera focus shifts, image blurring, and uneven image sharpness caused by board surface undulation and jumping. This ensures that the camera can accurately detect various defects such as board surface texture, minor scratches, color differences, pits, edge chipping, and edge sealing defects. It can clearly and completely collect data, eliminating problems such as false detection, missed detection, and fluctuations in detection accuracy caused by unstable imaging. This significantly improves the imaging quality and recognition accuracy of visual inspection, ensuring stable and reliable detection data. At the same time, the pressure-stabilizing and limiting mechanism has adaptive adjustment capabilities, which can automatically adapt the pressing state according to the thickness of the cabinet board. When the board thickness increases, it can simultaneously increase the pressing contact area and pressing force, ensuring that boards of different thicknesses can obtain a uniform and reliable top limiting effect. Moreover, the whole adopts a pressure-stabilizing and flexible pressing method, with uniform and controllable pressure. It will not cause indentations, scratches, or edge deformation on the board surface due to rigid extrusion. While achieving precise limiting, it effectively protects the appearance quality of the board. Attached Figure Description

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Please see Figures 1-8 This invention provides a technical solution: a visual intelligent detection device for board defects in cabinet processing, comprising an optical defect detection table 1, a conveyor frame 2, and an auxiliary frame 3. An installation plate 4 is installed at the bottom of the conveyor frame 2. Two sets of adjusting frames 5 are symmetrically slidable within the frames on both sides of the conveyor frame 2. A limiting plate 6 is provided at one end of each set of adjusting frames 5 through a thin rod at the top of the two sets of adjusting frames 5. An electric push rod 7 is installed at the top of the auxiliary frame 3. A drive plate 8 is installed at the bottom protruding end of the electric push rod 7. A buffer plate 9 is provided at the bottom of the drive plate 8. An anti-deviation adjustment mechanism is provided inside the installation plate 4. A movable frame 11 is installed at the bottom of the buffer plate 9. Two sets of pressure plates 12 are symmetrically slidable on the surface of the limiting rods on both sides of the movable frame 11. A pressure stabilizing and limiting mechanism is provided at the bottom of the buffer plate 9. An optical defect detection platform 1 is installed at the end of the conveyor frame 2, and the detection port of the optical defect detection platform 1 is at the same height as the conveyor frame 2. This equal-height alignment structure ensures that the board material is smoothly and without drop during the conveying process and transitions to the detection area. An auxiliary frame 3 is located around the conveyor frame 2 near one end of the optical defect detection platform 1. Several balls are installed on the mirror surfaces of the two sets of limiting plates 6. The rolling contact of the balls replaces the traditional sliding friction, which greatly reduces the lateral conveying resistance of the board material, avoids scratches and wear on the sides of the board material, and ensures smooth and unobstructed lateral guidance of the board material. The two sets of limiting plates 6 are located far away from the optical defect detection platform 1. The ends are equipped with inclined short plates; the inclined short plates at the ends of the two sets of limiting plates 6 are designed with openings inside the frame of the conveyor frame 2, and the openings are larger at the end away from the optical defect detection table 1, forming a funnel-shaped guide structure that is wider at the outside and narrower at the inside. This can automatically correct and guide the plates with slight deviations in the feeding position, realize the self-alignment of the plates for feeding, and eliminate the problems of plate jamming and deviation. The top of the buffer plate 9 is equipped with four sets of sliding rods, which are evenly distributed in the area near the edge of the buffer plate 9. The four sets of sliding rods slide within the drive plate 8 and are limited. Each of the four sets of sliding rods is fitted with a spring, and the top of the spring is connected to the drive plate 8. The bottom is connected to the buffer plate 9, and a symmetrical elastic buffer structure is formed by four sets of evenly distributed sliding rods and springs. This structure can achieve vertical flexible pressure stabilization and buffering, effectively absorbing the up-and-down jumping and vibration caused by high-speed conveying of the sheet material, ensuring uniform buffering force and flatness of the sheet surface, avoiding deformation of the sheet surface caused by single-point pressure, and stabilizing the vertical conveying posture of the sheet material. The two sets of pressure plates 12 are symmetrically arranged on both sides of the moving frame 11. The long plates at the bottom side of the two sets of pressure plates 12 are designed with an incline. The inclined plate surface can form a guide slope, which facilitates the smooth introduction of sheet materials of different thicknesses into the limiting area between the two sets of pressure plates 12, avoiding hard contact and jamming. Springs are fitted on the surfaces of the limiting rods on both sides of the frame 11. One end of the spring is connected to the protrusion at the end of the limiting rod, and the other end of the spring is connected to the pressure plate 12. Relying on the elastic adaptive expansion and contraction characteristics of the spring, the two sets of pressure plates 12 can adaptively adjust the clamping distance and pressing force according to the actual thickness of the board, forming an elastic fit and limiting on both sides of the board. This ensures the tightness of the limiting and avoids rigid compression damage to the board and the edge sealing structure. It ensures that the board is transported without deviation, fluctuation, or shaking, and ensures that the subsequent optical detection imaging position is accurate and the image is clear. From the mechanical structure level, it greatly improves the accuracy and stability of board defect detection.

[0020] As one embodiment of the present invention, the anti-deviation adjustment mechanism includes a rotating plate 101 mounted on the bottom of the mounting plate 4 via a motor, two sets of adjustment frames 5 with connecting rods 102 mounted on their bottoms respectively, the ends of the two connecting rods 102 being rotatably connected to the rotating plate 101, thin rods at the top of the two sets of adjustment frames 5 penetrating one end of the two side frames of the conveying frame 2 with push plates 103 mounted on one end, a plurality of sleeves 104 mounted on the end of the push plates 103, a limiting plate 6 near the frame end sliding within the sleeves 104, an adjustment plate 106 on the surface of the plurality of sleeves 104 sliding within a limiting position, a pressing rod 105 mounted on the top of the plurality of adjustment plates 106, and a pressing block 107 vertically arranged in the frame, a spring mounted on the side of the adjustment plate 106 near the limiting plate 6, the other end of the spring being connected to the limiting plate 6, an inclined surface being opened on the side end of the pressing block 107, and the inclined surface of the pressing block 107 abutting against the pressing rod 105; The controller drives the conveyor frame 2 to operate, and the motor drives the rotating plate 101 to rotate, which in turn pulls the connecting rod 102 to move the two sets of adjusting frames 5 towards the center of the frame. The sheet material is placed on the conveyor frame 2, with the limiting plates 6 on both sides conforming to the sides of the sheet material. Changes in the sheet material thickness will push the limiting plates 6 to slide along the sleeve 104. The matching spring, under pressure, generates elastic reaction force, ensuring that the limiting plates 6 always flexibly press against the sides of the sheet material. Relying on this elastic anti-deviation structure, it can dynamically adapt to sheets of different thicknesses, automatically adjusting the clamping force to prevent sheet material deviation and skewing during transport; it also uses flexible contact to avoid side squeezing, scratching, and damage to the edge sealing, perfectly protecting the appearance of the sheet material. The sheet material is transported smoothly and centrally throughout the process, effectively avoiding problems such as shooting point deviation and imaging misalignment caused by misalignment, ensuring the accuracy of optical inspection imaging. The equipment is compatible with processing sheet materials of multiple specifications, eliminating the need for repeated manual alignment and adjustment, simplifying the operation process, and continuously and stably improving inspection quality and conveying efficiency.

[0021] In one embodiment of the present invention, the pressure stabilizing and limiting mechanism includes a sleeve 131 rotatably connected to the bottom of the movable frame 11, an annular plate 132 installed at the bottom of the sleeve 131, a miniature push rod 133 installed inside the buffer plate 9, an extension rod 134 installed at the protruding end of the miniature push rod 133, a first oil tank 135 installed at the top of the movable frame 11, a first piston rod 136 slidingly limited inside the first oil tank 135, and the top of the first piston rod 136 connected to the protruding plate on the surface of the extension rod 134. It also includes a mechanism installed on the top of the conveyor frame 2. The second oil tank 137 has a second piston rod 138 that slides inside the second oil tank 137 and is connected to the extrusion block 107. The bottom of the extension rod 134 slides inside the sleeve 131 and the sleeve 131 has a spiral groove. The extension rod 134 has a protrusion that slides on the surface of the sleeve 131. The top of the pressure plate 12 has a cylindrical protrusion and the bottom of the pressure plate 12 has several balls. The ring plate 132 has an elliptical plate design and the side end of the ring plate 132 abuts against the cylindrical protrusion on the top of the pressure plate 12. The sheet material is conveyed to the bottom of the auxiliary frame 3, and the electric push rod 7 pushes the drive plate 8 downward. The bottom ball bearings of the pressure plate 12 adhere to the sheet surface. During the downward pressing process, the slide rod limits the sliding movement, and the spring is compressed to generate a reverse elastic force, so as to achieve flexible pressing of the sheet material and suppress the jumping and undulation of the sheet surface. When facing a thicker sheet material, the push rod stroke remains unchanged, and the spring compression increases accordingly, automatically increasing the pressing force. Simultaneously, the controller triggers the micro push rod 133 to move according to the plate thickness, driving the extension rod 134 to slide along the spiral groove, causing the sleeve 131 and the ring plate 132 to rotate, and pushing the pressure plate 12 outward to expand the spacing, thus widening the pressure coverage area. The entire pressure stabilization and limiting structure can adapt to different plate thicknesses, dynamically adjust the pressure force and contact area, stably constrain the movement of the plate, and eliminate the problems of focal length shift and image blur caused by frequent height changes. Various minor defects can be clearly imaged and captured, reducing false detections and missed detections. The flexible pressure mode will not damage the plate surface and edge sealing structure, ensuring both detection accuracy and data stability, and also protecting the appearance of the plate. It is suitable for continuous detection of multiple specifications of plates.

[0022] Working principle: During testing, the controller first drives the conveyor frame 2 to operate, and then the motor drives the rotating plate 101 to rotate. When the rotating plate 101 rotates, it pulls the two connecting rods 102. At the same time, the two connecting rods 102 are pulled and drive the two sets of symmetrically arranged adjusting frames 5 to slide towards the frame position of the conveyor frame 2. Then, the plate is placed on the surface of the conveyor frame 2, so that the limiting plate 6 contacts the side end of the plate. While the adjusting frame 5 moves, the limiting plate 6 is pressed by the side end of the plate and slides towards the push plate 103. At this time, the end of the limiting plate 6 near the frame slides in a limited position inside the sleeve 104. The spring on the surface of the adjusting plate 106 is squeezed by the limiting plate 6 and provides it with reverse elastic resistance, so that the side end of the limiting plate 6 always provides elastic resistance to the side end of the plate. This avoids damage to the side end of the plate and prevents the plate from shifting or tilting during transportation. When the sheet material is transported to the bottom of the auxiliary frame 3, the drive plate 8 is pushed down by the extended end of the electric push rod 7, so that the balls at the bottom of the two sets of pressure plates 12 come into contact with the surface of the sheet material. As the drive plate 8 continues to be pressed down, the top slide rod of the buffer plate 9 slides in the drive plate 8, so that the spring on the surface of the limit rod is in a compressed state. The reverse elastic force of the spring will push the buffer plate 9 to generate a downward force, so that the balls at the bottom of the pressure plate 12 and the sheet material achieve elastic pressing and contact. As the plate thickness increases, the extension distance of the electric push rod 7 remains constant. When the ball bearings of the pressure plate 12 contact the top of the thick plate, the spring on the surface of the limit rod is compressed and rises synchronously, thereby increasing the pressing force on the thick plate. At the same time, the controller drives the extension end of the micro push rod 133 to push the extension rod 134 down through the height of the thick plate. At this time, the protrusion on the surface of the extension rod 134 slides within the spiral groove inside the sleeve 131 and drives the sleeve 131 to rotate. The rotation of the sleeve 131 drives the ring plate 132 to rotate synchronously. At this time, the side end of the longer end of the ring plate 132 gradually squeezes the cylindrical protrusion on the top of the pressure plate 12, causing the two sets of pressure plates 12 to move away from the cylindrical protrusion. The moving frame 11 moves in the direction of increasing the distance between the two sets of pressure plates 12 and simultaneously expanding the pressing area on the thick plate. As the extension rod 134 moves downward, the surface protrusion squeezes the first piston rod 136. At this time, the oil inside the first oil tank 135 is squeezed and flows into the second oil tank 137. The increase in oil inside the second oil tank 137 pushes the second piston rod 138 to extend and pushes the pressing block 107. At this time, the inclined surface of the pressing block 107 abuts against the pressing rod 105, causing the pressing rod 105 to drive the adjusting plate 106 to move towards the limiting plate 6, thereby increasing the compression degree of the spring on the surface of the adjusting plate 106 and increasing the reverse elastic resistance force of the limiting plate 6 on the thick plate.
