Description

Technical Field

[0001] This invention relates to the field of ceramic surface inspection devices, specifically a ceramic surface roughness inspection device. Background Technology

[0002] Ceramic slabs are a common type of ceramic decoration and are widely used in daily life. To ensure the production quality of ceramic slabs, it is necessary to test the surface roughness of ceramic slabs. At present, in the field of ceramic slab surface roughness testing, laser scattering / diffraction instruments are widely used due to their non-contact, high precision and high efficiency.

[0003] Currently, mainstream laser scattering detection devices typically use a fixed-spot laser beam to cover the test area of ​​a ceramic plate through mechanical scanning or sample movement. However, in actual use, due to the diverse widths of ceramic plates, existing laser detection devices cannot adapt to the detection of ceramic plates of different widths. This results in the laser beam potentially reflecting off the stage when the ceramic plate is narrow, thus affecting the accuracy of the detection data. Summary of the Invention

[0004] The purpose of this invention is to provide a ceramic surface roughness detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ceramic surface roughness testing device, including a fixed frame, a worktable fixed on the fixed frame, a display mounted on the worktable, a cylinder fixed on the worktable, a platform above the worktable, and a dark box fixed on the left side of the worktable;

[0006] A limiting mechanism is used to clamp and limit the ceramic plate. The limiting mechanism is installed on the platform and is connected to the cylinder.

[0007] A self-locking mechanism is used to achieve the locking function of the limiting mechanism, and the self-locking mechanism is interconnected with the platform;

[0008] The detection mechanism adjusts the laser range to adapt to ceramic plates of different widths for detection. The detection mechanism is installed inside a dark box and is driven by a limiting mechanism.

[0009] Preferably, a U-shaped frame is symmetrically fixed to the lower end face of the platform, and the U-shaped frame is slidably connected to the guide rail. The U-shaped frame is symmetrically fixed to the worktable, and the stability of the platform movement can be ensured by the sliding guidance between the U-shaped frame and the guide rail when the platform moves.

[0010] Preferably, the limiting mechanism includes a clamping plate that slides in contact with the stage, and the clamping plate is symmetrically distributed about the center of the stage. The upper surface of the clamping plate is fixed with convex shafts at equal intervals. Through the action of the clamping plate, the ceramic plate can be clamped and limited to facilitate subsequent testing.

[0011] Preferably, a first toothed rod is fixed to the lower end face of the clamping plate, and the first toothed rod meshes with a gear to achieve transmission. The gear is fixed on a rotating shaft, and the rotating shaft is connected to the lower end face of the platform by a bearing. The gear meshes with a second toothed rod to achieve transmission, and the second toothed rod is fixed on a movable plate. The movable plate is fixed to the output end of the cylinder. The cylinder drives the movable plate and the second toothed rod to move. The meshing transmission between the second toothed rod, the gear, and the first toothed rod can provide a basic force for adjusting the position of the clamping plate, thereby providing a basic guarantee for clamping and limiting the ceramic plate.

[0012] Preferably, the movable plate and the guide rod are slidably connected, and the guide rod is fixed on the U-shaped frame. One end of a spring is also fixed on the movable plate, while the other end of the spring is fixed on the platform. Through the sliding guiding action between the movable plate and the guide rod, the stability of the movable plate's movement can be ensured. Through the elastic action of the spring, a basic force can be provided for the automatic reset of the movable plate.

[0013] Preferably, the self-locking mechanism includes a bracket fixed to the lower end face of the platform, and a square rod is slidably connected to the bracket. An iron locking block is fixed to the upper end of the square rod. The iron locking block and the lower end opening of the rotating shaft are nested to achieve a positioning function. The nesting between the iron locking block and the lower end opening of the rotating shaft can provide a basic guarantee for locking the rotating shaft.

[0014] Preferably, the square rod and the inclined plate are slidably connected, and the height of the inclined plate is greater than the height of the iron block. The inclined plate is fixed to the upper surface of the workbench. Through the sliding action between the square rod and the inclined plate and the gravity of the iron block, a basic force can be provided to realize the automatic unlocking of the rotating shaft.

[0015] Preferably, the detection mechanism includes a motor fixed to the right end face of the dark box, and the output end of the motor is connected to a threaded rod connected to a bearing inside the dark box. The threaded rod is threadedly connected to the movable box, which is located inside the dark box. The movable box is slidably connected to the crossbar, and the crossbar is symmetrically fixed inside the dark box. The threaded rod provides a basic force for the movement of the movable box, and the sliding guide between the movable box and the crossbar ensures the stability of the movable box's movement.

[0016] Preferably, a laser emitter is fixed on one side of the movable box, and a laser receiver is fixed on the other side of the movable box. The above structure can provide a basic guarantee for the detection of surface roughness of ceramic plates.

[0017] Preferably, the lower end face of the movable box contacts the light-shielding plate to form a sliding mechanism, and the light-shielding plate and the dark box are slidably connected. A vertical plate is also fixed on the light-shielding plate, and sliders are symmetrically fixed on the left and right sides of the vertical plate. The sliders are slidably connected to the dark box. A through-slot is also opened on the lower side of the vertical plate, and the slot is slidably connected to the convex shaft. Through the cooperation of the slot and the convex shaft, the vertical plate and the light-shielding plate can be provided with a basic force when the convex shaft moves, thereby realizing the automatic adjustment of the laser detection range and effectively ensuring the accuracy of the detection data.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This ceramic surface roughness testing equipment adopts a self-locking mechanism, which can lock the limiting mechanism during the ceramic plate loading process, thereby avoiding the impact of the elasticity of the spring on the normal operation of the device during the loading process. After the ceramic plate is loaded, the locking mechanism can be automatically released, ensuring that the clamping and fixing of subsequent workpieces and the adjustment of the laser detection range can be carried out normally, thus better meeting the actual use needs.

[0020] 2. This ceramic surface roughness testing equipment adopts a testing mechanism with adjustable laser irradiation range. During the testing process, it can automatically adjust the laser detection range according to the width of the ceramic plate, ensuring that the laser detection range automatically matches the width of the ceramic plate. This ensures that the laser spot completely covers the surface of the ceramic plate under test, avoiding reflection interference caused by laser overflow to the stage (such as metal or glass carrier). This improves the signal-to-noise ratio (SNR) of the scattered signal by more than 40%, and controls the Ra measurement error within ±2%, effectively ensuring the accuracy of the test data.

[0028] 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.

[0029] Please see Figures 1-6 The present invention provides a technical solution: a ceramic surface roughness detection device, including a fixed frame 1, a worktable 2 fixed on the fixed frame 1, a display 3 installed on the worktable 2, a cylinder 4 fixed on the worktable 2, a platform 5 arranged above the worktable 2, and a dark box 8 fixed on the left side of the worktable 2.

[0030] The limiting mechanism 6 is used to clamp and limit the ceramic plate. The limiting mechanism 6 is installed on the platform 5 and is connected to the cylinder 4.

[0031] The self-locking mechanism 7 is used to achieve the locking function of the limit mechanism 6, and the self-locking mechanism 7 is connected to the platform 5.

[0032] The detection mechanism 9 is installed inside the dark box 8 and is driven by the limiting mechanism 6. The laser range is adjusted to adapt to ceramic plates of different widths for detection.

[0033] A U-shaped frame 501 is symmetrically fixed to the lower end face of the platform 5, and the U-shaped frame 501 is slidably connected to the guide rail 502. The U-shaped frame 501 is symmetrically fixed to the worktable 2. The limiting mechanism 6 includes a clamping plate 601 that slides in contact with the platform 5. The clamping plate 601 is symmetrically distributed about the center of the platform 5. The upper end face of the clamping plate 601 is fixed with convex shafts 602 at equal intervals. A first convex tooth 603 is fixed to the lower end face of the clamping plate 601. The first convex tooth 603 meshes with a gear 604 to achieve transmission. The gear 604 is fixed to a rotating shaft 605. The rotating shaft 605 is bearing connected to the lower end face of the platform 5. The gear 604 meshes with a second convex tooth 606 to achieve transmission. The second convex tooth 606 is fixed to a movable plate 607. The movable plate 607 is fixed to the output end of the cylinder 4; the movable plate 607 and the guide rod 608 are slidably connected, and the guide rod 608 is fixed to the U-shaped frame 501. One end of the spring 609 is also fixed on the movable plate 607, and the other end of the spring 609 is fixed to the platform 5. The self-locking mechanism 7 includes a bracket 701 fixed to the lower end face of the platform 5, and a square rod 702 is slidably connected to the bracket 701. An iron block 703 is fixed to the upper end of the square rod 702, and the iron block 703 is nested with the lower end opening of the rotating shaft 605 to achieve positioning. The square rod 702 and the inclined plate 704 are slidably connected, and the height of the inclined plate 704 is greater than the height of the iron block 703. The inclined plate 704 is fixed to the upper end face of the worktable 2.

[0034] When using this ceramic surface roughness testing equipment, such as Figures 1-6 As shown, the ceramic plate to be tested is first placed on the stage 5 using a robotic arm with a suction cup. After the ceramic plate is placed, the lower end face of the square rod 702 contacts the plane of the inclined panel 704, so that the iron block 703 at the upper end of the square rod 702 and the opening at the lower end of the rotating shaft 605 are nested, that is, the rotating shaft 605 is locked. Then, by controlling the extension of the cylinder 4, the movable plate 607 is moved. Since the rotating shaft 605 is locked, the gear 604 cannot rotate. When the movable plate 607 moves, the stage 5 and the ceramic plate can be moved into the dark box 8 simultaneously, thereby realizing the automatic feeding of the ceramic plate. During the feeding process, the lower end face of the square rod 702 always slides in contact with the plane of the inclined panel 704.

[0035] During the feeding process, when the square rod 702 contacts and slides against the inclined surface of the inclined panel 704, the iron block 703 can move downward under its own weight. Combined with the sliding guide between the square rod 702 and the bracket 701, the stability of the movement of the iron block 703 can be ensured. When the left end of the platform 5 contacts the inner wall of the dark box 8, the square rod 702 slides to the inclined end of the inclined panel 704, and the iron block 703 separates from the lower opening of the rotating shaft 605, thereby automatically releasing the locking effect of the rotating shaft 605. At this time, the ceramic plate is located inside the dark box 8.

[0036] When the rotating shaft 605 is released from lock, the cylinder 4 continues to extend. Since the left end of the platform 5 contacts the inner wall of the dark box 8 to achieve a limit, the cylinder 4 continues to extend to provide force to the movable plate 607, thereby causing the movable plate 607 to move relative to the platform 5. With the sliding guidance between the movable plate 607 and the guide rod 608, the stability of the movement of the movable plate 607 can be ensured. At this time, the spring 609 is compressed. When the movable plate 607 moves, it drives the second toothed rod 606 to move synchronously. With the transmission between the second toothed rod 606 and the gear 604 and the transmission between the gear 604 and the first toothed rod 603, the two clamping plates 601 can move towards each other, reducing the distance between the two clamping plates 601 until the clamping plates 601 contact the ceramic plate, thus completing the limiting function of the ceramic plate. At this time, the central axis of the ceramic plate and the central axis of the dark box 8 are in the same vertical plane, so as to facilitate subsequent detection.

[0037] The detection mechanism 9 includes a motor 901 fixed to the right end face of the dark box 8. The output end of the motor 901 is connected to a threaded rod 902 with a bearing connected inside the dark box 8. The threaded rod 902 is threadedly connected to the movable box 903, which is located inside the dark box 8. The movable box 903 is slidably connected to a crossbar 904, which is symmetrically fixed inside the dark box 8. A laser emitter 905 is fixed to one side of the movable box 903. A laser receiver 906 is fixed on the other side of the inner box 3; the lower end face of the movable box 903 contacts the light shield 907 to form a sliding mechanism, and the light shield 907 is slidably connected to the dark box 8. A vertical plate 908 is also fixed on the light shield 907, and sliders 909 are symmetrically fixed on the vertical plate 908. The sliders 909 are slidably connected to the dark box 8. A through slot 910 is also opened on the lower side of the vertical plate 908, and the slot 910 is slidably connected to the convex shaft 602.

[0038] During the operation of the device, such as Figures 1-6As shown, when the stage 5 moves the ceramic plate into the dark box 8, it simultaneously moves the clamping plate 601 and the convex shaft 602. When the convex shaft 602 enters the dark box 8, it slides into the groove 910 on the lower side of the vertical plate 908 until the left end of the stage 5 contacts the inner wall of the dark box 8 for positioning. At this time, multiple convex shafts 602 on the clamping plate 601 are engaged with the groove 910. When the clamping plate 601 moves to limit the ceramic plate, it simultaneously moves the convex shaft 602, which in turn moves the vertical plate 908, coordinating with the slider. The sliding action between 909 and the dark box 8 ensures the stability of the movement of the vertical plate 908. The movement of the vertical plate 908 can synchronously drive the light-shielding plate 907 to move, thereby blocking the lower opening of the movable box 903 and adjusting the width of the lower opening of the movable box 903, thus controlling the laser detection range. When the clamping plate 601 contacts the ceramic plate, the width of the lower opening of the movable box 903 is exactly equal to the width of the ceramic plate, thus ensuring that the subsequent laser spot completely covers the ceramic plate and avoids laser overflow that affects the accuracy of the detection data.

[0039] During the testing process, the laser emitter 905 is activated, and the laser beam generated by the laser emitter 905 shines on the ceramic plate. After being reflected by the ceramic plate, it is received by the laser receiver 906. Based on the principle that when parallel light passes through a rough surface, some light will undergo diffuse reflection, and the intensity of the reflected parallel beam will decrease. The rougher the surface, the more diffuse reflection occurs, and the weaker the light intensity. This allows for the detection of the surface roughness of the ceramic plate. During the testing process, the motor 901 drives the threaded rod 902 to rotate. In conjunction with the threaded connection between the threaded rod 902 and the movable box 903, the movable box 903, the laser emitter 905, and the laser receiver 906 can be moved to achieve comprehensive testing of the ceramic plate.
