Description

Technical Field

[0001] This utility model relates to the field of ceramic glazing technology, specifically to a precise quantitative glazing device for daily-use ceramics. Background Technology

[0002] Daily-use ceramics are ceramic products closely related to people's daily lives, encompassing tableware such as bowls, plates, cups, and saucers. They are made primarily from clay, through processes of ingredient preparation, shaping, drying, and high-temperature firing. They combine practicality and decoration, with glazing being a key step in enhancing their performance and aesthetics. First, the glaze is evenly applied to the surface of the bisque-fired body using methods such as spraying or brushing. Then, a second high-temperature glaze firing is performed. After the glaze melts and cools, it forms a smooth, dense, glassy film. This glaze not only isolates moisture and prevents stains from penetrating, making the ceramics easier to clean, but also allows for the presentation of rich colors and luster, such as white glaze, celadon glaze, and polychrome glaze, by adjusting the glaze composition. At the same time, it conceals imperfections in the body, making daily-use ceramics both durable and possessing a delicate visual texture, meeting both daily use and aesthetic needs.

[0003] Currently, in the glazing process of daily-use ceramics, the method of quantitative glazing is usually adopted by controlling the amount of glaze applied. However, this method can only provide macroscopic control over the amount of glaze applied and cannot accurately correspond to the thickness of the glaze layer on the surface of the ceramic body. Furthermore, due to the differences in the shape and surface flatness of the ceramic body, even if the same amount of glaze is applied, the amount of glaze adhering to different areas of the body will be different, which can easily lead to local glaze layers that are too thick or too thin. This results in low accuracy of quantitative glazing, which may affect the consistency of the product's appearance and increase the scrap rate in subsequent firings. To address this, we propose a precise quantitative glazing device for daily-use ceramics. Utility Model Content

[0004] The purpose of this invention is to provide a precise quantitative glazing device for daily-use ceramics. This device can accurately glaze the surface of the ceramic body, ensuring a consistent glaze thickness, thereby improving the appearance quality of the ceramics and reducing the scrap rate during subsequent firing. It solves the problem that current methods for quantitative glazing in daily-use ceramics typically involve controlling the amount of glaze applied. However, this method only provides macroscopic control over the amount of glaze applied and cannot precisely correspond to the glaze thickness on the ceramic body surface. Furthermore, due to differences in the shape and surface flatness of the ceramic body, even with the same amount of glaze applied, the amount of glaze adhering to different areas of the body will vary, easily leading to localized excessively thick or thin glaze layers. This results in low precision in quantitative glazing, which may affect the consistency of product appearance and increase the scrap rate during subsequent firing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise quantitative glazing device for daily-use ceramics, comprising a base, a fixed seat, a conveyor and an electrical control box fixedly installed on the upper surface of the base, three robotic arms fixedly installed in a circular array at equal intervals near the edge of the upper surface of the fixed seat, a laser thickness gauge, a clamp and a spray head respectively fixedly installed at the output end of the three robotic arms, a material conveying pipe fixedly connected to the outer surface of the spray head, a flow meter fixedly connected to the end of the material conveying pipe, a regulating valve fixedly connected to the end of the flow meter, a turntable rotatably installed on the upper surface of the fixed seat, and three placement seats fixedly installed in a circular array at equal intervals inside the turntable.

[0006] Preferably, a material cylinder and a material pump are fixedly installed on the upper surface of the base, and the output end of the material pump and the end of the regulating valve are fixedly connected. A filter valve is fixedly connected to the input end of the material pump, and the end of the filter valve is fixedly connected to the outer surface of the material cylinder near the lower surface.

[0007] Preferably, a stirring motor is fixedly installed at the axial center position on the upper surface of the material cylinder, and a stirring paddle is fixedly connected to the end of the output shaft of the stirring motor, with the stirring paddle located inside the material cylinder.

[0008] Preferably, a feeding valve is fixedly connected to one side of the upper surface of the material cylinder.

[0009] Preferably, a rotating motor is fixedly installed inside the fixed base, and the end of the output shaft of the rotating motor is fixedly connected to the center position of the lower surface of the turntable.

[0010] Preferably, a Y-shaped partition is fixedly installed inside the turntable.

[0011] Preferably, a waste bin is fixedly installed on the upper surface of the base near the fixed seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the setup of a base, fixed seat, conveyor, robotic arm, turntable, laser thickness gauge, clamp, spray head, feed pipe, flow meter, regulating valve, and electrical control box, achieves precise glazing of the surface of daily-use ceramic blanks, ensuring a consistent glaze thickness, thereby improving the appearance quality of the ceramics and reducing the scrap rate during subsequent firing. In the automated glazing production line for ceramic blanks, the conveyor is responsible for the continuous transport of the blanks. When the blank is transported to a designated station near the fixed seat, the special clamp at the end of the first robotic arm precisely clamps the blank on the conveyor and places it stably on the turntable's placement seat. The turntable then rotates at a preset angle, moving the blank directly under the spray head. At this time, the second robotic arm drives its high-precision spray head to move, uniformly spraying the glaze onto the surface of the ceramic blank according to a set trajectory. After the spraying operation is completed, the turntable continues... The rotating mechanism transfers the blank to a position below the laser thickness gauge. The third robotic arm then moves the laser thickness gauge at its end to perform a comprehensive, non-contact inspection of the glaze thickness on the blank surface. After the inspection, the turntable rotates again, returning the blank to a position accessible to the initial clamp. If the glaze thickness is within acceptable limits, the clamp of the first robotic arm will hold the blank again, placing it back on the conveyor for transport to the next process. If the glaze thickness is found to be unacceptable, the clamp of the first robotic arm will hold the blank again and move the unacceptable blank to the scrap area. Simultaneously, the inspection data is transmitted to the control box in real time. For areas on the blank surface where the glaze thickness is unacceptable, the main control equipment will automatically optimize the spraying time and glaze application amount for the corresponding area in the subsequent spraying process, based on the location coordinates of that area and the deviation value of the unacceptable thickness, ensuring a significant improvement in the pass rate of the glaze thickness of subsequent blanks.

[0013] This invention divides the interior of the turntable into three areas by setting a Y-shaped partition, so as to avoid affecting the ceramic blanks in other areas when spraying glaze on the surface of the ceramic blank.

[0014] This invention, by setting a filter valve, can filter the glaze flowing out of the barrel, thereby removing particulate impurities and preventing the spray head from clogging.

[0015] By incorporating a stirring motor and a stirring paddle, this invention enables the stirring paddle, driven by the output shaft of the stirring motor, to stir the glaze inside the barrel, thereby ensuring uniform mixing of the glaze and improving the quality of subsequent glazing on the ceramic body surface.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0019] like Figures 1-4 As shown, this utility model proposes a precise quantitative glazing device for daily-use ceramics, comprising a base 3. A fixed seat 1, a conveyor 4, and an electrical control box 6 are fixedly mounted on the upper surface of the base 3. Three robotic arms 10 are fixedly mounted in a circular array at equal intervals near the edge of the upper surface of the fixed seat 1. A laser thickness gauge 11, a clamp 12, and a spray head 13 are respectively fixedly mounted at the output ends of the three robotic arms 10. A material conveying pipe 16 is fixedly connected to the outer surface of the spray head 13, and a flow meter 17 is fixedly connected to the end of the material conveying pipe 16. A regulating valve 18 is fixedly connected to the end of the flow meter 17. A turntable 7 is rotatably mounted on the upper surface of the fixed seat 1. A rotating motor 22 is fixedly mounted inside the fixed seat 1. The output shaft end of the rotating motor 22 and the lower surface of the turntable 7 are connected... The turntable 7 is fixedly connected at the axis position. Three placement seats 8 are fixedly installed in a ring array at equal intervals inside the turntable 7. A Y-shaped partition 9 is fixedly installed inside the turntable 7, which divides the interior of the turntable 7 into three areas to avoid affecting the ceramic blanks in other areas when spraying glaze on the surface of the ceramic blanks. A waste bin 5 is fixedly installed on the upper surface of the base 3 near the fixed seat 1. The electrical control box 6 is equipped with a main control device. The main control device adopts a Siemens S7-1500 series PLC, which can receive the detection data transmitted by the laser thickness gauge 11 in real time, and accurately control the motion parameters of the robotic arm 10 (such as spraying trajectory and moving speed) and the opening of the regulating valve 18 of the glaze conveying pipeline through the built-in PID adjustment algorithm.

[0020] In this invention, in an automated glazing production line for ceramic blanks, conveyor 4 is responsible for the continuous transport of daily-use ceramic blanks. When the blank is transported to a designated workstation near the fixed seat 1, the special clamp 12 at the end of the first robotic arm 10 precisely clamps the blank on the conveyor 4 and places it stably on the placement seat 8 of the turntable 7. Then, the turntable 7 rotates at a preset angle, moving the blank directly below the spray head 13. At this time, the second robotic arm 10 moves its high-precision spray head 13, uniformly spraying glaze onto the surface of the ceramic blank according to a set trajectory. After the spraying operation is completed, the turntable 7 continues to rotate, transferring the blank to below the laser thickness gauge 11. The third robotic arm 10 then moves the laser thickness gauge 11 at its end to perform a comprehensive, non-contact measurement of the glaze thickness on the surface of the blank. After the touch-sensitive inspection, the turntable 7 rotates again, returning the blank to a position accessible to the initial clamp 12. If the glaze thickness is qualified, the clamp 12 of the first robotic arm 10 will clamp the blank again, place it back on the conveyor 4, and transport it to the next process. If the glaze thickness is found to be unqualified, the clamp 12 of the first robotic arm 10 will clamp the blank again and move the unqualified blank to the waste bin 5. At the same time, the inspection data is transmitted to the electrical control box 6 in real time. For the unqualified glaze thickness in a certain area of ​​the blank surface found during the inspection, the main control equipment inside the electrical control box 6 will combine the position coordinates of the area and the unqualified thickness deviation value to automatically optimize the spraying time and glaze spraying amount of the corresponding area in the subsequent spraying process, ensuring that the pass rate of the glaze thickness of the subsequent blanks is greatly improved.
