Description

Technical Field

[0002] Large ceramic slabs are large-sized ceramic products, and their definition is as follows: ‌Material and process‌: Made from inorganic non-metallic materials such as clay and ore, formed by pressing and calcined at high temperature (≥1200°C), and are plate-shaped products with a surface area ≥1.62㎡. ‌Specification characteristics‌: Breaking through the traditional tile size (such as 600×600mm), common specifications include 750×1500mm, 900×1800mm, and even larger.

[0003] When producing large ceramic slabs, it is usually necessary to detect their size and flatness. In the prior art, industrial cameras are usually used to take segmented pictures of the surface of large ceramic slabs, and then the taken pictures are integrated, so that the size of the slabs and whether there are depressions or cracks on the surface can be visually observed using a display. However, since industrial cameras have high requirements for light sources during shooting, and during shooting, the reflection on the surface of large ceramic slabs and the ambient stray light will affect the accuracy of shooting.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-9, the present invention provides a technical solution: an automatic inspection device for ceramic large panels, including a main body assembly 1, characterized in that: the main body assembly 1 includes a plurality of support members 101, and the plurality of support members 101 are connected by reinforcing ribs 102.

[0023] The annular light mechanism 21 includes an A moving plate 2101, a mounting member 2102 and an annular light source 2103. The A moving plate 2101 is slidably installed on the surface of the longitudinal movement structure 108. The mounting member 2102 is fixedly connected to one end of the A moving plate 2101. A plurality of annular light sources 2103 are provided, and the plurality of annular light sources 2103 are all installed at one end of the mounting member 2102.

[0024] The annular light mechanism 21 further includes a connection hole 2105, a sliding rod 2106, a deflection member 2107 and a placement plate 2110. The placement plate 2110 is fixedly connected to the upper end of the A fixing plate 104. A deflection groove 2108 and a sliding groove 2109 are formed on the surface of the placement plate 2110. A connection hole 2105 is formed on the surface of the A moving plate 2101. The sliding rod 2106 is rotatably connected to the connection hole 2105. The deflection member 2107 is fixedly connected to the surface of the sliding rod 2106. The sliding rod 2106 is slidably connected to the inside of the sliding groove 2109. The deflection member 2107 is slidably connected to the inside of the deflection groove 2108. The sliding rod 2106 is connected to the mounting member 2102.

[0025] A torsion spring 2104 is installed on the inner wall of the connection hole 2105, and the torsion spring 2104 is connected to the surface of the sliding rod 2106.

[0026] The control assembly 22 includes a lifting member 2201 and a hollow member 2202. The hollow member 2202 is slidably connected to the upper end of the concave member 106. The lifting member 2201 is fixedly connected to the upper end of the hollow member 2202.

[0027] The control component 22 further includes a rectangular plate 2203 and a limiting rod 2205. A moving groove 2204 is formed on the surface of the rectangular plate 2203. The limiting rod 2205 is fixedly connected to one end of the lifting member 2201, and the limiting rod 2205 is slidably connected to the inside of the moving groove 2204.

[0028] The specific implementation manner of this embodiment is as follows: When detecting whether there are depressions or cracks on the surface of the large ceramic plate, the longitudinal moving structure 108 can drive the A moving plate 2101 and the rectangular plate 2203 to move. During the movement of the two, the sliding rod 2106 will slide in the sliding groove 2109, and the deflecting member 2107 will slide in the deflecting groove 2108. When the two slide, since the middle sections of the deflecting groove 2108 and the sliding groove 2109 are both lifted upward, when the sliding rod 2106 passes through the lifting section, the lifting member 2201 will be lifted at this time. And because the width of the deflecting groove 2108 will become narrower after the end of the lifting section, at this time, the deflecting member 2107 will be squeezed, so that the deflecting member 2107 will deflect at an angle, and then the mounting member 2102 can be driven to lift and deflect, so that the surface of the large ceramic plate can be filled with light by the annular light source 2103. And because a plurality of annular light sources 2103 are provided and all are annular light beams, the illumination of the annular light source 2103 will reduce the specular reflection of the large ceramic plate and enhance its diffuse reflection, so that there will be no large bright blocks in the photos taken by the subsequent industrial inspection camera 309, thus improving the detection accuracy. When there is a large depression on the large ceramic plate, during this period, through the oblique illumination of the annular light source 2103, a large-area shadow can be generated at the depression. At this time, it can be observed by the naked eye of the worker. If there is a small depression, the shadow generated at this time is small and inconvenient to observe with the naked eye. At this time, through the shooting of the industrial inspection camera 309, the shadow position can be directly observed, so that it can be concluded that the large ceramic plate does not meet the production standard. In specific use, since when the annular light source 2103 irradiates, in order to make the shadow part at the depression more obvious when the light source irradiates the depression, the annular light source 2103 usually needs to be deflected to a certain extent, and at the same time of deflection, a certain amount of lifting is required, so that the light can make the shadows at shallower or deeper depressions more obvious. In use, the mounting member 2102 can be moved, so that the annular light source 2103 can be moved horizontally, and then the surface of the large ceramic plate can be irradiated. When the mounting member 2102 moves, the sliding rod 2106 will move in the sliding groove 2109. As the continuous movement progresses, when it moves to the lifting section of the sliding groove 2109, the lifting member 220 will rise accordingly, so that the mounting member 2102 and the annular light source 2103 can be driven to rise. And because the deflecting member 210 in the deflecting groove 2108 slides, and the width of the front section of the deflecting groove 2108 is the same as the height of the deflecting member 2107, while the width of the lifting section will gradually decrease, so that the deflecting member 2107 will deflect, and at this time, the mounting member 2102 and the annular light source 2103 will be driven to deflect, so that the light can be obliquely irradiated on the surface of the large ceramic plate. In order to make the lifting member 2201 drop when the mounting member 2102 returns to its original position after the detection is completed,Moreover, the angles of the deflecting member 2107 and the annular light source 2103 will return to their original angles. Therefore, a torsion spring 2104 can be provided on the sliding rod 2106. When it is necessary to rotate the sliding rod 2106, the elastic force of the torsion spring 2104 can drive the sliding rod 2106 to rotate, and then the light of the annular light source 2103 can be made to irradiate the ceramic large plate parallel again.,

[0029] Embodiment 2: Please refer to Figures 1-9 , the present invention provides a technical solution: The coaxial light detection assembly 3 includes a contact plate 301 and two B fixing plates 302. The two B fixing plates 302 are respectively slidably connected to the upper ends of the A fixing plate 104 and the concave member 106, and the contact plate 301 is fixedly connected between the two B fixing plates 302.

[0030] The coaxial light detection assembly 3 further includes an L-shaped plate 303, an A motor 304, a rack 305 and an A gear 306. The rack 305 is fixedly connected to the upper end of the rectangular plate 2203. The L-shaped plate 303 is fixedly connected to one end of the B fixing plate 302. The A motor 304 is fixedly connected to one end of the L-shaped plate 303. The A gear 306 is fixedly connected to the output end of the A motor 304, and the A gear 306 meshes with the rack 305.

[0031] An extension plate 308 is fixedly connected to the upper end of the B moving plate 401. A clamping plate 313 is slidably connected to the upper end of the concave member 106. A rotating plate 307 is rotatably connected between the extension plate 308 and the clamping plate 313. A protective cover 312 is fixedly connected to the lower end of the rotating plate 307. A beam splitter 310 and an LED light source 311 are fixedly connected inside the protective cover 312, and the beam splitter 310 and the LED light source 311 are at a 45° angle. An industrial inspection camera 309 is provided inside the protective cover 312, and the industrial inspection camera 309 is fixedly connected to the rotating plate 307.

[0032] The specific implementation of this embodiment is as follows: When detecting whether there are cracks on the surface of the ceramic large plate, in order to avoid the influence of ambient stray light on the shooting accuracy of the industrial detection camera 309, a protective cover 312 can be sleeved outside the industrial detection camera 309, and a beam splitter 310 and an LED light source 311 are fixedly arranged inside the protective cover 312. When shooting, the LED light source 311 is a light source composed of high-density LEDs, providing high-intensity uniform illumination. The beam splitter 310 is a semi-transparent and semi-reflective mirror or prism set at 45°. The beam splitter 310 can reflect the light of the LED light source 311 onto the ceramic large plate and allow the reflected light of the object to penetrate to the industrial detection camera 309. During use, a film coating treatment is required on the surface of the beam splitter 310 to reduce light loss, such as advanced coating to improve the transmittance, and a black light-absorbing layer is arranged on the upper surface of the beam splitter 310 to absorb stray light. A diffuser plate is arranged at the end of the LED light source 311. During use, after the LED light is homogenized by the diffuser plate, it is projected onto the beam splitter 310 set at 45°. The beam splitter 310 reflects about 50% of the light to form vertically incident light to illuminate the surface of the ceramic large plate. The reflected light from the surface of the ceramic large plate returns vertically to the beam splitter 310. The beam splitter 310 transmits about 50% of the reflected light to the industrial detection camera 309, and the remaining light is absorbed by the black light-absorbing layer. Through the above structure, the shadow interference caused by oblique illumination can be eliminated, which is suitable for the detection of defects on mirror or highly reflective surfaces such as scratches and pits. And because the incident light and the reflected light are coaxially arranged, coaxial imaging can be formed. The optical axis of the industrial detection camera 309 coincides with the incident light to ensure high-contrast imaging of surface micro-features such as micron-level cracks, so as to form high-precision detection of the surface of the ceramic large plate. During use, in order to make the rotating plate 307 always perpendicular to the ceramic large plate, before detection, the A motor 304 can be operated to drive the A gear 306 to rotate, and then the contact plate 301, the B fixing plate 302 and the L-shaped plate 303 can be controlled to move. By pressing the rotating plate 307 with the contact plate 301, the rotating plate 307 can always be perpendicular to the ceramic large plate, and the detection accuracy is higher.

[0033] Embodiment 3: Please refer to Figures 1-9, the present invention provides a technical solution: The size detection component 4 includes a B moving plate 401, a B gear 402, a large-size ceramic plate flatness measuring instrument 403, a lifting plate 404, a screw rod 405, and a B motor 406. The B moving plate 401 is slidably mounted on the upper end of the longitudinal moving structure 108. The lifting plate 404 is slidably connected to one end of the B moving plate 401. The large-size ceramic plate flatness measuring instrument 403 is fixedly connected to one end of the lifting plate 404. The screw rod 405 is rotatably connected to the upper end of the B moving plate 401. The lifting plate 404 is threadedly connected to the screw rod 405. The B motor 406 is mounted on the upper end of the B moving plate 401. The B gear 402 is rotatably connected to the upper end of the B moving plate 401, and the B gear 402 is fixedly sleeved on the surface of the screw rod 405. The output end of the B motor 406 is connected to the B gear 402.

[0034] The specific implementation manner of this embodiment is as follows: When detecting the size and flatness of the large ceramic plate, the horizontal position of the B moving plate 401 can be adjusted by operating the longitudinal moving structure 108. During the adjustment, the size of the large ceramic plate can be measured by the large-size ceramic plate flatness measuring instrument 403, and at this time, the flatness of the ceramic surface can be detected by the large-size ceramic plate flatness measuring instrument 403, so as to remove the obvious protrusions on the surface. When in use, in order to perform size detection, the B motor 406 can be operated to drive the B gear 402 to rotate, and then the screw rod 405 can be driven to rotate, so that the lifting plate 404 threadedly connected to the screw rod 405 can be lifted, and then the large-size ceramic plate flatness measuring instrument 403 can be lifted. The lifted large-size ceramic plate flatness measuring instrument 403 can detect the height of the large ceramic plate.
