DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] A ceramic ware surface quality detection device, such as Figure 1-Figure 7As shown, it includes a base 1 supported on the ground by legs 5, a ring-shaped conveying mechanism 2 is arranged on the top of the base 1, the top transmission of the ring-shaped conveying mechanism 2 is matched with multiple sets of rotating clamps 3 for fixing ceramic vessels, and an image acquisition mechanism 4 is arranged on the side wall of the base 1.

[0027] The image acquisition mechanism 4 includes a support frame 8 fixed to the side wall of the base 1 by bolts and a slider 9 slidably connected to the support frame 8. A support plate 13 is fixed to the top of the slider 9 by bolts, and an image acquisition camera 14 for taking photos or videos of ceramic vessels is fixed to the side wall of the support plate 13.

[0028] The inner wall of the slider 9 is slidably connected with a limiting slide rod 6 which contacts and cooperates with the rotating clamping table 3. The other end of the limiting slide rod 6 is fixed with an end plate 11 by bolts. The side wall of the end plate 11 is buckled with a return spring 10. The other end of the return spring 10 is buckled to the side wall of the slider 9. The side wall of the support frame 8 is fixed with an inclined platform 12 by bolts. The inclined platform 12 contacts and cooperates with the end plate 11 in a limiting manner. The side wall of the slider 9 is buckled with a return spring 7. The other end of the return spring 7 is buckled to the inner wall of the support frame 8.

[0029] When the device is in use, the ceramic vessel can be fixed by the rotating clamping table 3, and then the annular conveying mechanism 2 conveys the rotating clamping table 3. When it is conveyed to the position of the image acquisition mechanism 4, the image acquisition camera 14 will take pictures or videos of the ceramic vessel on the rotating clamping table 3, and at the same time, the rotating clamping table 3 will push the limiting slide bar 6, and the limiting slide bar 6 drives the slider 9 and the image acquisition camera 14 to move, so that the image acquisition camera 14 moves synchronously with the ceramic vessel. During the movement, the end plate 11 is limited by the inclined table 12, so that the limiting slide bar 6 is gradually withdrawn from the rotating clamping table 3. After it is completely withdrawn, the reset spring 7 pushes the slider 9 to reset. In this embodiment, the subsequent processing after the image acquisition camera 14 collects the image for defect detection is a prior art. For example, the patent disclosed as CN205388578U has been disclosed, which is also the common knowledge of those skilled in the art. Specifically, an image without defects can be first collected as a standard image, and then the collected image is compared with the standard image. Since this embodiment does not make creative work on it, it will not be repeated.

[0030] The device transports the ceramic vessel by setting up a ring-shaped conveying mechanism 2 to convey the rotating clamping table 3, and utilizes the mutual limitation of the limiting slide bar 6 and the rotating clamping table 3 during image acquisition, so that the image acquisition camera 14 and the ceramic vessel can move synchronously, thereby making the captured image clearer without pausing the conveying, thereby improving the detection efficiency.

[0031] In order to solve the transportation problem; Figure 3As shown, the annular conveying mechanism 2 includes a fixed chain plate 16 and a double-row movable chain 22, the fixed chain plate 16 is fixed to the top outer wall of the base 1, and the inner walls at both ends of the double-row movable chain 22 are meshed with fixed sprockets 23, the fixed sprocket 23 is rotatably connected to the top outer wall of the base 1, and a low-speed motor 24 is fixed to the bottom outer wall of the base 1 by bolts, and the output shaft of the low-speed motor 24 is fixed to the outer wall of one of the fixed sprockets 23 by bolts.

[0032] The rotating clamping platform 3 includes a turntable 19 and a clamping assembly 20 arranged on the top of the turntable 19 . The bottom outer wall of the turntable 19 is rotatably connected to a guide platform 18 through a sleeve 17 .

[0033] The bottom transmission of the sleeve 17 is matched with a movable sprocket 15 , and the movable sprocket 15 is engaged with the opposite side of the fixed chain plate 16 and the double-row movable chain 22 .

[0034] A support platform 25 is fixed to the top outer wall of the base 1 by bolts. A guide groove 21 is provided on the top inner wall of the support platform 25 and the fixed chain plate 16. A limit shaft 27 that is movable and limited to the inner wall of the guide groove 21 is fixed to the bottom of the guide platform 18.

[0035] When in use, the ceramic vessel can be clamped by the clamping assembly 20. When the low-speed motor 24 is started, it can drive the fixed sprocket 23 to rotate, thereby driving the double-row movable chain 22 to move, so that the fixed chain plate 16 rotates while moving along the gap between the double-row movable chain 22 and the fixed chain plate 16. At the same time, when the movable sprocket 15 moves, it can drive the sleeve 17 to rotate, thereby driving the turntable 19 to rotate.

[0036] This device, by setting up a ring-shaped conveying mechanism 2 and a rotating clamping table 3 that cooperate with each other, adopts a "kneading" type of driving for the movable sprocket 15 based on the "chain transmission", so that the movable sprocket 15 can not only be circular closed-type conveying but also rotate on its own. On the one hand, the circular closed-type conveying can realize assembly line detection and improve detection efficiency. On the other hand, the self-rotation can also make the ceramic vessel rotate at a low speed, thereby increasing the comprehensiveness of image acquisition.

[0037] A slope raising block 26 is fixed to the inner wall of the guide groove 21 at the image acquisition station, and the limiting shaft 27 is in contact with the slope raising block 26 .

[0038] A transmission shaft 31 is fixed to the top outer wall of the movable sprocket 15, and the transmission shaft 31 is movably inserted into the inner wall of the sleeve 17. A pawl 30 is provided on the outer wall of the transmission shaft 31, and a ratchet groove 28 engaged with the ratchet 30 and an annular groove 29 for the ratchet 30 to rotate freely are provided on the inner wall of the sleeve 17.

[0039] When the rotating clamp 3 moves to the image acquisition station, the limit shaft 27 will be limited by the slope lifting block 26 and lifted as a whole, so that the pawl 30 engages with the ratchet groove 28. At this time, the movable sprocket 15 can reliably drive the sleeve 17 to rotate. When it is in the non-image acquisition station, the rotating clamp 3 as a whole is lowered by gravity, the pawl 30 is located in the annular groove 29 and rotates freely, and the sleeve 17 does not rotate.

[0040] The device, by setting a slope lifting block 26 and setting the movable sprocket 15 and the sleeve 17 as a clutch-type transmission, can ensure the reliable rotation of the ceramic vessel at the image acquisition station, increase the comprehensiveness of the acquisition, and also ensure that the remaining states do not rotate, increase the convenience of taking and placing materials. At the same time, whether the movable sprocket 15 and the sleeve 17 are engaged or not depends entirely on the limit of the slope lifting block 26, without the need for manual or electronic control algorithm interference, thereby simplifying the control logic.

[0041] When the present embodiment is in use, the ceramic vessel can be fixed by the rotating clamping table 3, and then the annular conveying mechanism 2 conveys the rotating clamping table 3. When it is conveyed to the position of the image acquisition mechanism 4, the image acquisition camera 14 will take pictures or videos of the ceramic vessel on the rotating clamping table 3, and at the same time, the rotating clamping table 3 will push the limiting slide bar 6, and the limiting slide bar 6 drives the slider 9 and the image acquisition camera 14 to move, so that the image acquisition camera 14 and the ceramic vessel move synchronously. During the movement, the end plate 11 is limited by the inclined table 12, so that the limiting slide bar 6 is gradually pulled out from the rotating clamping table 3. After it is completely pulled out, the reset spring 7 pushes the slider 9 to reset. When in use, the ceramic vessel can be clamped by the clamping assembly 20. When the low-speed motor 24 is started, it can drive the fixed sprocket 23 to rotate, thereby driving the double-row movable chain 22 to move, so that the fixed chain plate 16 rotates while moving along the gap between the double-row movable chain 22 and the fixed chain plate 16. At the same time, when the movable sprocket 15 moves, it can drive the sleeve 17 to rotate, thereby driving the turntable 19 to rotate. When the rotating clamp 3 moves to the image acquisition station, the limiting shaft 27 will be limited by the slope lifting block 26 and raised as a whole, so that the pawl 30 engages with the ratchet groove 28. At this time, the movable sprocket 15 can reliably drive the sleeve 17 to rotate. When it is in the non-image acquisition station, the rotating clamp 3 as a whole is lowered by gravity, the pawl 30 is located in the annular groove 29 and rotates freely, and the sleeve 17 does not rotate.

[0042] A ceramic ware surface quality detection device, such as Figure 1-Figure 7 As shown, in order to solve the clamping problem, this embodiment makes the following improvements on the basis of embodiment 1: the clamping components 20 are arranged on the top of the turntable 19 in three groups of circular arrays.

[0043] The clamping assembly 20 includes a slide 32 slidably connected to the radial direction of the turntable 19 and a limiting wheel 33 rotatably connected to the inner wall of the slide 32 . The side wall of the slide 32 is buckled with a spring 34 , and the other end of the spring 34 is buckled to the inner wall of the turntable 19 .

[0044] The ceramic container can be placed inside the plurality of limiting wheels 33 and fixed by the tension provided by the spring 1 34 .

[0045] In order to solve the stability problem, the clamping assembly 20 also includes a slide 2 37 slidably connected to the inner wall of the turntable 19, a counterweight block 41 and a lever 40 rotatably connected to the turntable 19, and both ends of the lever 40 are provided with strip grooves 39, and the slide 2 37 and the counterweight block 41 are respectively limited and matched in the two strip grooves 39 through the limiting protrusions 38, and the strip grooves 39 are slidably matched with the slide 1 32 through the guide rod 43, and the outer wall of the guide rod 43 is provided with a spring 2 42.

[0046] When rotating, the counterweight 41 will also rotate. When the counterweight 41 rotates, it will be affected by the centrifugal force and tend to move outward, thereby squeezing the slide 2 37 inward through the transformation of the lever 40, so that the spring 2 42 is compressed, and the slide 2 37 fits with the limiting wheel 33, exerting an inward squeezing force. When the rotational movement disappears, the squeezing force disappears.

[0047] Since the ceramic vessel may not be a completely rotationally symmetrical shape, it will be subjected to eccentric force during rotation. In order to overcome the eccentric force, a large static pulling force provided by spring 1 34 is required. A large static pulling force will make it inconvenient to take and place the ceramic vessel. Therefore, based on this, the device is provided with a counterweight block 41, and the centrifugal force exerted on the counterweight block 41 during rotation is then applied to the slide 2 37 through the action of lever 40, so that the inward clamping force of the slide 1 32 is greater and the clamping stability is better. When the rotation stops, the clamping force provided by the centrifugal force disappears, and will not affect the taking and placing of the ceramic vessel.

[0048] A tooth groove 35 is formed on the outer wall of the middle portion of the limiting wheel 33 , and a rack 36 engaged with the tooth groove 35 is formed on the end surface of the second slide 37 .

[0049] In this device, by setting the tooth groove 35 and the rack 36, when the slide 37 applies an inward extrusion force to the limiting wheel 33, the engagement of the rack 36 and the tooth groove 35 will also limit the rotation of the limiting wheel 33, thereby further preventing unstable clamping caused by eccentric force, and at the same time will not hinder the convenience of taking and releasing materials.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
