Description

Technical Field

[0001] This invention relates to the field of injection molded panel production inspection technology, specifically to an integrated inspection device for surface defects in injection molded panels. Background Technology

[0002] Injection-molded panels, as common structural and appearance components manufactured using injection molding processes, are widely used in products such as home appliances, automobiles, and electronic devices. Their appearance quality and dimensional accuracy directly affect the overall performance and usability of the products. Currently, the industry's quality inspection of injection-molded panels mainly focuses on surface condition, external dimensions, and edge forming quality. Through corresponding testing equipment or processes, the appearance and structural quality of the injection-molded panels are judged to ensure the quality stability of the products leaving the factory.

[0003] For example, patent CN208537378U discloses a surface defect detection device for injection molded panels. A conveyor belt is mounted on a base to transport the injection molded panels and is connected to a motor drive. A defect detection device is positioned above the conveyor belt. A base is mounted on the base, and a vertical plate is vertically mounted on the base. A first fixed plate and a second fixed plate are respectively positioned on the side of the vertical plate facing the conveyor belt. The first fixed plate has a first groove on the side facing the conveyor belt, and the second fixed plate has a second groove on the side facing the conveyor belt. The first groove is rotatably connected to the first fixed plate, and the second groove is rotatably connected to the second fixed plate. An image detection device has a first slider that matches the first groove, and a barcode scanner has a second slider that matches the second groove. This device can detect injection molded panels of different specifications and meet the detection requirements of different angles.

[0004] For example, patent CN217484202U discloses a surface defect detection device for injection molded panels, including a base plate, a support plate fixedly connected to the upper surface of the base plate, a drive mechanism fixedly connected to the right side of the support plate, a second hollow block fixedly connected to the right side of the support plate, a second bearing fixedly connected to the inner wall of the second hollow block, a U-shaped column fixedly connected to the inner wall of the second bearing, and a worm gear fixedly connected to the surface of the U-shaped column; by setting up a support plate, drive mechanism, second hollow block, second bearing, U-shaped column, worm gear, connecting block and fixing mechanism, wherein when the stepper motor in the drive mechanism is turned on, the stepper motor drives the worm gear The rotation, through the cooperation of the worm gear and worm wheel, changes the angle between the placement plate and the support plate, thereby automatically adjusting the angle of the injection-molded panel on the placement plate. However, stress concentration occurs at the edges of the injection-molded panel, which can easily lead to defects such as cracking, material shortage, and flash during the molding process. Since the panel edges are mostly beveled or rounded transition structures with a small angle between them and the inspection lens, weak or even no light reflection is likely to occur. Furthermore, the edge contour is easily obscured by its own structure, forming an imaging blind spot. This makes it difficult to detect defects in the edge area and hinders the achievement of comprehensive and high-quality inspection of the injection-molded panel surface.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing injection-molded panel production and testing equipment. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated inspection device for surface defects in injection molded panels, in order to solve the problem mentioned in the background art that stress concentration occurs at the edges of injection molded panels, which easily leads to defects such as cracking, material shortage, and flash during the molding process. Since the edges of the panels are mostly beveled or rounded transition structures, the angle between them and the inspection lens is small, which easily results in weak light reflection or even no effective reflection. In addition, the edge contour is easily obscured by its own structure, thus forming an imaging blind spot, making it difficult to detect defects in the edge area and making it difficult to achieve comprehensive and high-quality inspection of the injection molded panel surface.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated surface defect detection device for injection molded panels, comprising a detection table and an inner support frame centrally fixed on the detection table. A hollow spherical cover is fixedly installed on the inner support frame, and a rotatable steering rod is fitted inside the hollow spherical cover. A carrier platform for detecting injection molded panels is fixed on the upper surface of the steering rod. A steering mechanism is provided on the detection table to drive the carrier platform to tilt and flip sequentially in four directions. An outer support frame is fixed on the detection table, and four sets of fixed seats are fixed on the outer support frame. Laser sensors facing the surface of the carrier platform are fixed on the fixed seats, and a detection camera is arranged in the middle area of ​​the four sets of laser sensors. A primary cross slide frame is centrally fixed on the outer support frame through the four sets of fixed seats, and a displacement mechanism is provided on the fixed frame to drive the detection camera to move directionally along the primary cross slide frame as the carrier platform moves.

[0008] Preferably, the steering mechanism includes four sets of secondary cross slide frames fixedly installed at the bottom of the vehicle platform, the four sets of secondary cross slide frames being symmetrically distributed in pairs outside the steering ball; secondary guide slides are provided through the secondary cross slide frames in four directions, and secondary slide seats are slidably installed in the secondary guide slides.

[0009] Preferably, a base is fixedly installed on the lower surface of the secondary slide, and a spherical steering rod is fitted and rotated in the base; a longitudinal cylinder is fixed on the upper surface of the testing platform, and a spherical steering rod is fixed at the output end of the longitudinal cylinder.

[0010] Preferably, four sets of cylindrical rods are fixed on the inner side of the secondary cross slide frame along the four sliding directions. A fixed plate is fixed on the side of the cylindrical rod away from the secondary slide block, and a pressure plate is slidably sleeved on the side of the cylindrical rod close to the secondary slide block. A limit spring is elastically connected between the pressure plate and the fixed plate. A cylindrical channel is opened through the secondary slide block along the four sliding directions. The secondary slide block moves in a directional manner through the cylindrical channel and is sleeved on the outside of the cylindrical rod.

[0011] Preferably, the platform is provided with strip-shaped grooves in four directions, and clamping blocks are slidably connected in the strip-shaped grooves. A transverse cylinder is fixed on the side of the platform, and the output end of the transverse cylinder is fixedly connected to the clamping block.

[0012] Preferably, the displacement mechanism includes a primary guide slide that runs through the primary cross slide frame in four directions, a primary slide block that is slidably installed in the primary guide slide, and the primary slide block that is fixedly installed on the upper surface of the detection camera.

[0013] Preferably, the displacement mechanism further includes a driven support rod that is slidably connected to the primary cross slide frame along four directions. A push plate is fixed on the side of the driven support rod near the primary slide block, and a square slider is fixed next to the push plate and slidably connected in the primary guide slide. A follower plate is fixedly installed on the driven support rod, and a return spring is elastically connected between the follower plate and the primary cross slide frame.

[0014] Preferably, an active support rod is slidably connected through the outer support frame, and a power rod is vertically fixed on the side of the active support rod closest to the detection camera; a fixed disc is fixedly installed on the outer support frame, a movable disc is fixed on the active support rod, and a positioning spring is elastically connected between the movable disc and the fixed disc.

[0015] Preferably, a lateral support rod is obliquely fixed on the power rod, and a cylindrical tube is fixedly installed on the lateral support rod; a hollow seat is fixed on the upper surface of the first-stage cross slide frame, and a pull rope is slidably connected through the hollow seat. The two ends of the pull rope are fixedly connected to the driven support rod and the power rod respectively, and the pull rope is fitted to the outside of the cylindrical tube.

[0016] Preferably, four sets of longitudinal bars are fixedly installed on the upper surface of the vehicle platform, and crossbars are vertically fixed between the four sets of longitudinal bars, with the crossbars in a horizontal state and in contact with the side of the power rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the integrated surface defect detection equipment for injection molded panels first uses a laser sensor and a detection camera to detect the flatness, warpage and surface defects of the injection molded panel in a horizontal state, and then uses the detection camera to detect the edge defects of the injection molded panel in a tilted state. The integrated equipment completes the comprehensive inspection in stages, thereby improving the integrity and accuracy of the surface inspection of injection molded panels.

[0018] The inspection platform is equipped with a steering mechanism that drives the carrier to tilt and flip in four directions in sequence. After routine inspection of the horizontal injection-molded panel, the two sets of longitudinal cylinders in different directions are controlled to operate, so that the output ends of the two sets of longitudinal cylinders on one side extend and the output ends of the two sets of longitudinal cylinders on the other side retract. This causes the carrier to rotate to one side through the steering ball joint fitted in the hollow spherical cover, causing one edge of the injection-molded panel to tilt and flip. The inspection camera can collect image information of this edge at close range, so that the inclined surfaces, rounded corners and chamfered corners that are originally prone to forming imaging blind spots are fully imaged, thereby clearly identifying defects such as cracks, missing material, and flash at the edge, and realizing effective detection of edge defects of injection-molded panels.

[0019] When the longitudinal cylinder is running, it drives the secondary slide to move in a directional manner within the secondary cross slide frame. The secondary slide moves and is sleeved on the outside of the cylindrical rod, and its side contacts the pressure plate, pushing the pressure plate sleeved on the outside of the cylindrical rod to move. When the pressure plate moves, it compresses the limiting spring, which provides elastic buffering and speed limiting for the movement of the secondary slide, thereby assisting in the stability of the platform's rotation and tilting process.

[0020] The fixed frame is equipped with a displacement mechanism that drives the detection camera to move directionally along the primary cross slide frame as the carrier platform moves. When the carrier platform tilts and rotates, it drives the longitudinal and transverse rods to rotate synchronously. The transverse rod squeezes the power rod, which drives the driven support rod to move through the pull rope, pushing the primary slide block to move in the primary guide slide. This controls the detection camera to move towards the side of the carrier platform that is tilted upwards, further shortening the distance between the detection camera and the edge of the injection-molded panel on the surface of the carrier platform. This allows the detection camera to clearly identify the edge of the injection-molded panel at a shorter distance, enabling high-precision identification of edge defects in the injection-molded panel.

[0036] 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.

[0037] Example 1: Please refer to Figures 1-10 The present invention provides the following technical solution: an integrated inspection device for surface defects in injection molded panels, comprising an inspection table 1 and an inner support frame 2 centrally fixed on the inspection table 1. A hollow spherical cover 3 is fixedly installed on the inner support frame 2. A rotatable steering rod 4 is fitted inside the hollow spherical cover 3. A carrier table 5 for inspecting injection molded panels is fixed on the upper surface of the steering rod 4. A steering mechanism is provided on the inspection table 1 to drive the carrier table 5 to tilt and flip sequentially in four directions. An outer support frame 6 is fixed on the inspection table 1. Four sets of fixed seats 7 are fixed on the outer support frame 6. Laser sensors 8 facing the surface of the carrier table 5 are fixed on the fixed seats 7. A detection camera 10 is provided in the middle area of ​​the four sets of laser sensors 8. A primary cross slide frame 9 is centrally fixed on the outer support frame 6 through four sets of fixed frames 11. A displacement mechanism is provided on the fixed frames 11 to drive the detection camera 10 to move directionally along the primary cross slide frame 9 as the carrier table 5 moves.

[0038] Please see Figures 2-7The steering mechanism includes four sets of secondary cross slide frames 12 fixedly installed at the bottom of the platform 5. The four sets of secondary cross slide frames 12 are symmetrically distributed in pairs outside the steering ball rod 4. Secondary guide slides 13 are opened through the secondary cross slide frames 12 in four directions, and secondary slide seats 14 are slidably installed in the secondary guide slides 13. A base 15 is fixedly installed on the lower surface of the secondary slide seat 14, and a spherical steering rod 16 is fitted and rotated in the base 15. A longitudinal cylinder 17 is fixed on the upper surface of the detection platform 1, and the spherical steering rod 16 is fixed at the output end of the longitudinal cylinder 17. Four sets of cylindrical rods 18 are fixed on the inner side of the secondary cross slide frame 12 along the four sliding directions. A fixed plate 181 is fixed on the side of the cylindrical rod 18 away from the secondary slide block 14. A pressure plate 182 is slidably sleeved on the side of the cylindrical rod 18 close to the secondary slide block 14. A limit spring 183 is elastically connected between the pressure plate 182 and the fixed plate 181. A cylindrical channel 19 is opened through the secondary slide block 14 along the four sliding directions. The secondary slide block 14 moves in a directional manner through the cylindrical channel 19 and is sleeved on the outside of the cylindrical rod 18.

[0039] Please see Figures 2-4 The platform 5 has strip-shaped grooves 51 along four directions, and clamping blocks 52 are slidably connected in the strip-shaped grooves 51. A transverse cylinder 53 is fixed on the side of the platform 5, and the output end of the transverse cylinder 53 is fixedly connected to the clamping block 52.

[0040] The injection-molded panel to be inspected is placed on the carrier table 5. The horizontal cylinder 53 is operated to control the movement of the clamping block 52, so that the clamping block 52 slides along the direction of the strip groove 51. The clamping block 52 moves closer to the edge of the injection-molded panel. The four sides of the injection-molded panel are clamped and limited by the clamping blocks 52 in four directions, thereby quickly limiting the injection-molded panel to be inspected on the carrier table 5.

[0041] Initially, the platform 5 is horizontal. At this time, four sets of laser sensors 8 detect the distance to multiple locations on the surface of the injection-molded panel, acquiring the height data of each measuring point. The laser sensors 8 transmit the detection data to the background intelligent controller. The controller performs fitting and difference calculation on the multi-point height data. Based on the deviation value between each measuring point and the fitting reference plane, it analyzes and obtains the flatness and warpage of the injection-molded panel. The detection camera 10 collects image information of the injection-molded panel surface to identify surface defects, thereby realizing rapid detection of the flatness, warpage, and surface defects of the injection-molded panel surface in a horizontal state.

[0042] During further inspection of edge defects in the injection-molded panel, two sets of longitudinal cylinders 17 are simultaneously operated on one side of the carrier platform 5. The output end of the longitudinal cylinder 17 in this direction pushes the spherical steering rod 16 upward, while the output end of the two sets of longitudinal cylinders 17 on the other side drives the spherical steering rod 16 downward. The spherical steering rod 16 rotates inside the base 15. At this time, the two sides of the carrier platform 5 are at different heights. (After the carrier platform 5 rotates, the secondary slide 14 moves along the inclined direction in the secondary guide slide 13. After the secondary slide 14 moves, it is sleeved on the outside of the cylindrical rod 18 through the cylindrical channel 19, and the edge of the secondary slide 14 contacts and squeezes the pressure plate 182. The pressure plate 182 is sleeved on the outside of the cylindrical rod 18.) The movement of the part elastically compresses the limiting spring 183, which restricts the movement speed of the secondary slide 14 and keeps the platform 5 rotating stably. This causes the platform 5 to rotate along the steering ball 4 below, which is fitted into the hollow ball cover 3, thus tilting the platform 5 to one side. The injection-molded panel held above the platform 5 rotates synchronously with it. One side of the injection-molded panel tilts upward, and after the angle changes, the detection camera 10 can more clearly capture the edge defects on that side. By controlling the output or retraction of the longitudinal cylinders 17 on different sides, the platform 5 can be controlled to tilt and rotate in four directions in sequence, thereby realizing the sequential defect detection of the four edges of the injection-molded panel.

[0043] Example 2: Please refer to Figures 8-14 Based on Embodiment 1, a displacement mechanism is also disclosed, the specific structure of which is as follows: The displacement mechanism includes a primary guide slide 20 that runs through the primary cross slide frame 9 in four directions. A primary slide block 21 is slidably installed in the primary guide slide 20, and the primary slide block 21 is fixedly installed on the upper surface of the detection camera 10. The displacement mechanism also includes a driven support rod 22 that runs through and slides through the primary cross slide frame 9 in four directions. A push plate 23 is fixed on the side of the driven support rod 22 near the primary slide block 21. A square slider 24 that is slidably connected in the primary guide slide 20 is fixed next to the push plate 23. A follower plate 221 is fixedly installed on the driven support rod 22, and a return spring 222 is elastically connected between the follower plate 221 and the primary cross slide frame 9.

[0044] Please see Figures 11-14An active support rod 25 is slidably connected through the outer support frame 6. A power rod 26 is vertically fixed to the side of the active support rod 25 closest to the detection camera 10. A fixed disc 251 is fixedly installed on the outer support frame 6, and a movable disc 252 is fixed on the active support rod 25. A positioning spring 253 is elastically connected between the movable disc 252 and the fixed disc 251. A lateral support rod 261 is obliquely fixed on the power rod 26, and a cylindrical tube 262 is fixedly installed on the lateral support rod 261. A hollow seat 28 is fixed to the upper surface of the first-stage cross slide frame 9. A pull rope 27 is slidably connected through the hollow seat 28. The two ends of the pull rope 27 are fixedly connected to the driven support rod 22 and the power rod 26, respectively, and the pull rope 27 is fitted against the outside of the cylindrical tube 262. Four sets of longitudinal bars 263 are fixedly installed on the upper surface of the platform 5. A crossbar 264 is vertically fixed between the four sets of longitudinal bars 263. The crossbar 264 is horizontal and fits against the side of the power rod 26.

[0045] When the platform 5 rotates, it drives the longitudinal rod 263 and the transverse rod 264 to rotate synchronously. The transverse rod 264 on the downward tilting side of the platform 5 presses against the adjacent power rod 26. The power rod 26 drives the active support rod 25 to move in a directional manner through the outer support frame 6. The fixed disc 251 fixed on the active support rod 25 moves and presses against the positioning spring 253. The power rod 26 moves and stretches the pull rope 27, causing the pull rope 27 to move through the hollow seat 28. The other side of the pull rope 27 drives the driven support rod 22 to slide through the first-stage cross slide frame 9. The driven support rod 22 moves in the opposite direction to the active support rod 25. The driven support rod 22 moves towards the side of the platform 5 that is tilted upward, and its end face... The fixed push plate 23 pushes the first-stage slide block 21 to move inside the first-stage cross slide frame 9, causing the first-stage slide block 21 to also move towards the side of the carrier platform 5 that is tilted upwards. This causes the detection camera 10 fixed below the first-stage slide block 21 to move closer to the side of the injection molded panel that is tilted upwards, improving the clarity of the detection camera 10 in identifying edge defects of the injection molded panel. After detection, the carrier platform 5 is controlled to rotate and reset to a horizontal state. At this time, under the elastic thrust of the reset spring 222 and the positioning spring 253, the driven support rod 22 and the active support rod 25 are controlled to move and reset, keeping the power rod 26 moved and reset next to the crossbar 264, preparing for the next edge detection.
