Abstract
Description
Technical Field
[0001] This invention relates to the field of ceramic processing equipment technology, specifically to a glazing device and its usage method for producing ceramic casseroles. Background Technology
[0002] Ceramic casserole glazing equipment, as a surface treatment device that meets the needs of large-scale production, glaze forming and quality control of ceramic casseroles, is an important forming and processing equipment in the field of daily ceramic production. The automated glazing device, as the key core component for achieving uniform glazing and efficient mass production of casseroles on a normal temperature blank, directly determines the quality of the finished casserole, production efficiency and cost control level through its glazing uniformity, coverage accuracy and glaze recovery efficiency.
[0003] Currently, in the automated glazing application of deep-cavity ceramic casserole blanks, traditional manual glazing and glazing devices face numerous technical bottlenecks, severely restricting the finished product quality and large-scale production efficiency. Traditional glazing methods for casserole mostly employ dipping or single-sided glazing. Dipping is limited by manual labor, while automated glazing can only glaze one side of the casserole. Furthermore, it suffers from inherent problems such as glaze accumulation in the deep cavity, blind spots on the inner wall, and uneven glaze thickness between the inner and outer walls, which cannot be fundamentally avoided. It is also susceptible to interference from human error, differences in blank structure, and unstable glaze flow, leading to incomplete glaze coverage, glaze drips, and glaze accumulation. This fails to meet the high-precision, uniform glazing requirements of casserole. Moreover, traditional glazing processes are often carried out in open factory workshops, where environmental factors can cause problems. When issues such as substandard temperature or fluctuations in glaze viscosity occur, risks such as glaze shrinkage, pinholes, and insufficient adhesion can easily arise, making it difficult to guarantee the quality of the finished product. Existing glazing devices mostly rely on manual transfer to achieve multi-sided glazing, which is usually difficult to adapt to the glazing requirements of full glaze coverage for clay pots. Their adaptability to working conditions is insufficient. For example, glazing dead zones are prone to occur on deep-cavity blanks of different diameters, and the leveling of the glaze is out of control under temperature and humidity fluctuations. Although there are a few ceramic devices with multi-sided glazing functions, their structures are complex, the risk of jamming of moving parts is high, and the solutions such as flipping glazing, residual glaze recovery, and temperature control are not coordinated. They cannot achieve integrated closed-loop control of glazing status, process linkage, and quality control, making it difficult to adapt to the continuous high-precision glazing and large-scale stable production requirements of deep-cavity ceramic clay pot blanks.
[0004] Therefore, we propose a glazing device and its usage method for the production of ceramic casseroles in order to solve the problems mentioned above. Summary of the Invention

This invention upgrades the traditional single-sided glazing technology for ceramic casserole, which relies on manual assistance, to an automated two-stage glazing process with integrated temperature control. This significantly improves the uniformity of glazing, production efficiency, and finished product qualification rate of ceramic casseroles, meeting the stringent requirements of large-scale casserole production in the daily-use ceramics industry for low glaze loss, high batch consistency, and strong adaptability to working conditions.

The execution arm segment at one end of the robotic arm is equipped with a suction cup, which is used to flip the casserole after the first glazing and perform a second glazing. The glaze liquid tends to accumulate in the concave part of the casserole after the first glazing. Therefore, the suction cup and the execution arm segment are connected in a flow.

Four rotating shafts are inserted between two crossbars, and rollers are rotatably connected to the outer surfaces of the four rotating shafts.
[0010] Preferably, the outer surfaces of the four rollers are connected by multiple rubber rings that rotate together, and all of the rubber rings are used to transport the casserole. The transport structure composed of multiple rubber rings allows excess glaze to fall smoothly into the two glaze storage pools during the glazing process.

[0012] Preferably, the power output end of the motor is rotatably connected to a roller, and the outer surface of the roller is rotatably connected to a belt. The belt is used to drive a shaft to rotate the roller when the reducer rotates.
[0013] Preferably, the casserole control assembly includes a base, a first arm segment rotatably connected to the top of the base, a second arm segment rotatably connected to one end of the outer wall of the first arm segment, a third arm segment rotatably connected to one end of the outer wall of the second arm segment, and an actuating arm segment rotatably connected to the inner wall of the third arm segment.
[0014] Preferably, a first pump is bolted to one side of the outer wall of the third arm section, a first control pipe is connected to the input end of the first pump, a second control pipe is connected to the output end of the first pump, and the other end of the second control pipe is connected to one side of the outer wall of the glaze storage tank.
[0015] Preferably, the glazing temperature control component includes two sliding brackets, with a glazing bell jar on the opposite side of the two sliding brackets. A flow guide ring is provided on the top of the glazing bell jar, and a protective bottom cover is fixedly connected to the bottom of the glazing bell jar. Both heating plates are bolted to the top of the outer wall of the protective bottom cover.
[0016] Preferably, a second pump is bolted to one side of the outer wall of a sliding bracket, and a first glazing pipe is connected to the output end of the second pump. A glazing bracket is fixedly connected to the outer surface of the glazing bell, and a glazing nozzle is provided at the top of the glazing bracket. The other end of the first glazing pipe is connected to one side of the outer wall of the glazing nozzle.
[0017] Preferably, the input end of the second pump is connected to a second glazing pipe, and the other end of the second glazing pipe is connected to one side of the outer wall of the glaze storage tank.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] In this invention, the systematic collaboration of various modules in the clay pot control component and the glazing temperature control component achieves a unified approach to uniform glazing, efficient mass production, and quality control. The two-stage glazing component, formed by the combination of a multi-joint robotic arm and a suction cup, eliminates inherent problems such as deep cavity glaze accumulation, incomplete inner wall coverage, and uneven glaze thickness during the glazing process through its automatic flipping and negative pressure glazing extraction structure. The heating plate temperature control component integrated within the glazing bell jar ensures stable glaze flow during the glazing process by utilizing the adaptive characteristics of the body temperature and glaze fluidity through constant temperature control, thus mitigating the impact of environmental temperature changes. This invention addresses the risks of glaze defects such as dripping, glaze shrinkage, and pinholes caused by viscosity fluctuations. Firstly, it employs a dual-stage glazing process combined with active temperature control to ensure glazing quality and production safety. The invention utilizes a structure design combining automatic robotic arm rotation with negative pressure glaze extraction. A multi-jointed robotic arm performs the rotation of the clay pot and the second-stage glazing, significantly improving the glaze coverage and uniformity of the deep cavity wall, ensuring consistent glaze thickness on both the inner and outer walls, and greatly reducing the risk of glaze dripping caused by glaze accumulation in the inner cavity. Furthermore, the integrated heating plate's constant temperature control mechanism ensures stable body temperature during the glazing process. Firstly, it effectively avoids the potential for fluctuations in glazing quality caused by changes in ambient temperature or batch differences in the blanks. Secondly, it improves production efficiency through process integration and structural simplification. The glazing device integrates five major functions: conveying, glazing by turning, residual glaze recovery, temperature control, and anti-splash protection. Through core components such as conveying rollers, multi-jointed robotic arms, glazing bell jars, heating plates, and glaze storage tanks, it achieves efficient and continuous glazing, significantly reducing equipment complexity and failure rate. It realizes automated closed-loop control of blank conveying, precise glazing, and residual glaze recovery, reducing the loss that may be caused by manual turning, glazing, and cleaning. The core design, which eliminates the need for complex operations and frequent shutdowns for cleaning, gives the equipment high stability and low maintenance costs, perfectly meeting the needs of large-scale continuous production of clay pots in the daily-use ceramics industry. This invention upgrades the traditional single-sided glazing technology for ceramic clay pots, which relies on manual assistance, to an automated two-stage glazing process with integrated temperature control. This significantly improves the uniformity of glazing, production efficiency, and finished product qualification rate of ceramic clay pots, meeting the stringent requirements of large-scale clay pot production in the daily-use ceramics industry for low glaze loss, high batch consistency, and strong adaptability to various operating conditions.

Detailed Implementation
[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] like Figures 1-2 As shown, this embodiment discloses a glazing device and its usage method for ceramic casserole production, including a casserole transfer assembly 100, which has two glaze storage tanks 113 connected in circulation between the two glaze storage tanks 113, and the glaze storage tanks 113 are used to store glaze liquid.
[0030] like Figures 3-4As shown, the casserole control assembly 200 has a robotic arm composed of multiple joints. The execution arm segment 205 at one end of the robotic arm is equipped with a suction cup 206. The suction cup 206 is used to flip the casserole after the first glazing and perform a second glazing. Glaze liquid easily accumulates in the concave part of the casserole after the first glazing. Therefore, the suction cup 206 and the execution arm segment 205 are connected in a flow. The glaze liquid is extracted through the first control tube 208 inserted on one side of the outer wall of the execution arm segment 205.
[0031] like Figure 6 As shown, the glazing temperature control component 300 is equipped with two heating plates 304, which are used to regulate the temperature of the casserole during glazing.
[0032] This embodiment primarily addresses the numerous technical bottlenecks inherent in traditional manual glazing and glazing devices used in the automated glazing application of deep-cavity ceramic casseroles. These bottlenecks severely restrict the finished product quality and large-scale production efficiency of the casseroles. Traditional glazing methods primarily employ dipping or single-sided glazing. Dipping is limited by manual labor, while automated glazing can only glaze one side of the casseroles. Furthermore, it suffers from inherent problems such as glaze accumulation in the deep cavity, blind spots on the inner wall, and uneven glaze thickness between the inner and outer walls, which cannot be fundamentally avoided. These issues are also susceptible to human error, differences in the casseroles' structure, and unstable glaze flow, leading to incomplete glaze coverage and glaze drips / accumulations. This fails to meet the high-precision, uniform glazing requirements of casseroles. Moreover, traditional glazing processes are often conducted in open factory workshops. When problems such as substandard ambient temperature or fluctuations in glaze viscosity occur, risks such as glaze shrinkage, pinholes, and insufficient adhesion can easily arise, making it difficult to guarantee the quality of the finished product. Existing glazing devices mostly rely on manual transfer to achieve multi-sided glazing, which is usually difficult to adapt to the glazing requirements of full glaze coverage for clay pots. Their adaptability to working conditions is insufficient. For example, glazing dead zones are prone to occur on deep-cavity blanks of different diameters, and the leveling of glaze is out of control under temperature and humidity fluctuations. Although there are a few ceramic devices with multi-sided glazing functions, their structures are complex, the risk of jamming of moving parts is high, and the solutions such as flipping glazing, residual glaze recovery, and temperature control are not coordinated. They cannot achieve integrated closed-loop control of glazing status, process linkage, and quality control, making it difficult to adapt to the continuous high-precision glazing and large-scale stable production requirements of deep-cavity ceramic clay pot blanks.
[0033] This embodiment addresses the problems of the prior art by systematically coordinating various modules of the clay pot control component 200 and the glazing temperature control component 300. This achieves a unified approach to uniform glazing, efficient mass production, and quality control. The two-stage glazing component, formed by the combination of a multi-joint robotic arm and a suction cup 206, utilizes an automatic flipping and negative pressure glazing design to eliminate inherent problems such as deep cavity glaze accumulation, incomplete inner wall coverage, and uneven glaze thickness during the glazing process.

To ensure stable glaze flow during the glazing process and avoid glaze defects such as sagging, glaze shrinkage, and pinholes caused by environmental temperature changes and viscosity fluctuations, this invention employs a dual-stage glazing process combined with active temperature control to guarantee glazing quality and production safety. The invention utilizes a structure design combining automatic robotic arm rotation with negative pressure glaze extraction. The multi-jointed robotic arm performs the rotation of the clay pot and the second-stage glazing, significantly improving the glaze coverage and uniformity of the deep cavity wall, ensuring consistent glaze thickness on both the inner and outer walls, and greatly reducing the risk of glaze sagging caused by glaze accumulation in the inner cavity. Furthermore, the integrated heating plate 304's constant temperature control mechanism ensures stable glazing throughout the process. The stable temperature of the green body effectively avoids potential fluctuations in glazing quality caused by changes in ambient temperature or batch variations. Secondly, the integrated process and simplified structure enhance production efficiency. The glazing device integrates five functions: conveying, glazing by turning, residual glaze recovery, temperature control, and anti-splash protection. Through core components such as the conveying roller 105, multi-jointed robotic arm, glazing bell jar 302, heating plate 304, and glaze storage tank 113, it achieves efficient, continuous glazing, significantly reducing equipment complexity and failure rate. It realizes automated closed-loop control of green body conveying, precise glazing, and residual glaze recovery, reducing manual turning. The core design eliminates the need for complex operations and frequent shutdowns for cleaning, thus preventing errors during glazing and cleaning. This results in high stability and low maintenance costs, perfectly suited to the large-scale continuous production needs of clay pots in the daily-use ceramics industry. This invention upgrades the traditional single-sided glazing technology for ceramic clay pots, which relies on manual assistance, to an automated two-stage glazing process with integrated temperature control. This significantly improves the uniformity of glazing, production efficiency, and finished product qualification rate, meeting the stringent requirements of large-scale clay pot production in the daily-use ceramics industry for low glaze loss, high batch consistency, and strong adaptability to various operating conditions.
[0034] according to Figures 1-2 As shown, the casserole transfer assembly 100 includes a support frame 101, four legs 102 at the bottom of the support frame 101, and crossbars 103 on both sides of the top of the support frame 101. Four rotating shafts 104 are inserted between two crossbars 103, and rollers 105 are rotatably connected to the outer surfaces of the four rotating shafts 104.
[0035] In this embodiment of the invention, the support frame 101 and the four bottom legs 102 first form a stable bearing base. The height of the legs 102 can be adapted to the leveling requirements of the workshop floor, avoiding problems such as frame shaking and blank displacement during transmission. The crossbar 103 provides a precise installation positioning reference for the rotating shaft 104 and the roller 105, ensuring that the coaxiality error of multiple rollers 105 is controlled within the design range, avoiding jamming and deviation during transmission. At the same time, the rotating connection structure of the rotating shaft 104 and the roller 105 can evenly transmit the power of the drive end to the entire transmission surface, ensuring the smooth transport of the clay pot blank during the glazing process, and providing a stable foundation for subsequent precise glazing and robotic arm grasping and flipping.
[0036] according to Figure 2 As shown, the outer surfaces of the four rollers 105 are connected by multiple rubber rings 106 that rotate together, and the multiple rubber rings 106 are all used to transport the casserole. The transport structure composed of multiple rubber rings 106 allows excess glaze liquid during the glazing process to fall smoothly into the two glaze storage pools 113.
[0037] In this embodiment of the invention, the perforated conveyor surface composed of multiple rubber rings 106 has moderate friction to firmly fix the clay pot blank and prevent slippage during the conveying and glazing process. It also provides an unobstructed falling channel for excess glaze, avoiding the problems of glaze accumulation and glaze sticking to the bottom of the blank caused by solid conveyor belts. The rubber rings 106 are made of food-grade high-temperature resistant silicone material, which will not cause impact damage to the clay pot blank. At the same time, they have excellent resistance to glaze corrosion and can work stably in the glaze immersion environment for a long time. In addition, this perforated conveyor structure can ensure that the excess glaze splashed and dripped during the glazing process can be completely recycled into the glaze storage tank 113, which greatly improves the utilization rate of glaze and reduces the pollution of equipment and workshop environment by glaze.
[0038] according to Figure 2 As shown, a fixing plate 107 is bolted to one side of the outer wall of a crossbar 103, a motor 108 is bolted to one side of the outer wall of the fixing plate 107, a reducer 109 is provided on one side of the outer wall of the motor 108, and a housing 112 is bolted to the other side of the outer wall of the crossbar 103. The housing 112 is used to prevent impurities from entering the casserole transfer assembly 100.
[0039] In this embodiment of the invention, the fixing plate 107 first provides rigid mounting support for the motor 108 and the reducer 109. The bolt connection between the fixing plate 107 and the crossbar 103 ensures the connection between the drive component and the transmission frame, and facilitates disassembly and replacement during later maintenance. The drive structure of the motor 108 and the reducer 109 can precisely control the transmission speed to adapt to the glazing requirements of different sizes of clay pots, avoiding the problem of the blank shifting due to excessive transmission speed and the impact on production efficiency due to excessively slow transmission speed. At the same time, the outer shell 112 can completely cover the transmission end of the transmission component, effectively preventing dust, glaze splashes, and blank debris in the workshop from entering the transmission structure, avoiding bearing jamming and transmission failure, and extending the service life of the transmission component.
[0040] according to Figure 2 As shown, a roller 110 is rotatably connected to the power output end of the motor 108, and a belt 111 is rotatably connected to the outer surface of the roller 110. The belt 111 is used to drive a rotating shaft 104 to rotate the drum 105 when the reducer 109 rotates.
[0041] In this embodiment of the invention, the flexible transmission structure composed of roller 110 and belt 111 can smoothly transmit the power output by motor 108 to rotating shaft 104, avoiding vibration and impact caused by rigid transmission, reducing the shaking of the clay pot blank during transmission, and providing a stable working environment for precise glazing. The belt 111 has overload slip protection characteristics. When the transmission structure jams or is overloaded, it can slip to prevent motor 108 from burning out, improving the safety of equipment operation. At the same time, this belt transmission structure is easy to install and maintain, requiring no complicated lubrication and maintenance. It is suitable for the harsh working conditions of ceramic production workshops with high dust and glaze contamination, and can transmit power stably for a long time, ensuring the stability of continuous production.
[0042] according to Figures 3-4 As shown, the casserole control assembly 200 includes a base 201, a first arm segment 202 rotatably connected to the top of the base 201, a second arm segment 203 rotatably connected to one end of the outer wall of the first arm segment 202, a third arm segment 204 rotatably connected to one end of the outer wall of the second arm segment 203, and an actuating arm segment 205 rotatably connected to the inner wall of the third arm segment 204.
[0043] In this embodiment of the invention, the base 201 firstly provides a stable mounting foundation for the multi-joint robotic arm, ensuring the positioning accuracy of the robotic arm throughout the entire process of grasping, flipping, and discharging, and avoiding problems such as the blank falling or misalignment caused by movement deviation. The multi-segment rotating joint structure composed of the first arm segment 202, the second arm segment 203, and the third arm segment 204 has multi-degree-of-freedom motion capability, which can cover the entire stroke of the conveyor line loading, glazing station grasping, flipping, and second-stage glazing discharging. It is suitable for the flipping and glazing requirements of clay pot blanks of different diameters and depths. At the same time, the rotatable design of the execution arm segment 205 can accurately adjust the adsorption angle of the suction cup 206 to ensure the fit and sealing with the clay pot blank, providing precise motion support for the core processes of subsequent negative pressure adsorption, internal cavity residual glaze extraction, and flipping second-stage glazing. Structurally, it realizes the automation upgrade of traditional manual flipping and glazing.
[0044] according to Figures 3-4 As shown, a first pump 207 is bolted to one side of the outer wall of the third arm section 204. A first control pipe 208 is connected to the input end of the first pump 207. A second control pipe 209 is connected to the output end of the first pump 207. The other end of the second control pipe 209 is connected to one side of the outer wall of the glaze storage tank 113.
[0045] In this embodiment of the invention, the first pump 207 provides a stable power source for negative pressure adsorption and residual glaze extraction. Its bolted connection with the third arm section 204 allows it to move synchronously with the robotic arm. The first control pipe 208 is connected to the suction cup 206 through the execution arm section 205. It can firmly fix the clay pot blank through negative pressure adsorption to ensure that it will not fall off during the flipping process. It can also quickly extract the excess glaze liquid accumulated in the deep cavity of the clay pot before flipping, which solves the problem of glaze accumulation in the inner cavity and glaze liquid dripping and contamination during the flipping process in traditional single glazing. At the same time, the second control pipe 209 directly transports the extracted residual glaze back to the glaze storage tank 113, realizing the real-time recycling and reuse of glaze liquid, greatly reducing glaze loss. It also forms an integrated closed loop of adsorption, glaze extraction and recycling, which perfectly matches the process requirements of the two-stage glazing process of flipping, improving the glazing quality and production efficiency.
[0046] according to Figures 5-7 As shown, the glazing temperature control assembly 300 includes two sliding brackets 301. A glazing bell jar 302 is provided on the opposite side of the two sliding brackets 301. A flow guide ring 310 is provided on the top of the glazing bell jar 302. A protective bottom cover 303 is fixedly connected to the bottom of the glazing bell jar 302. Two heating plates 304 are bolted to the top of the outer wall of the protective bottom cover 303.
[0047] In this embodiment of the invention, the sliding bracket 301 first provides an adjustable mounting support for the glazing bell jar 302, which can flexibly adjust the installation position of the glazing bell jar 302 according to the different heights of the casserole blanks, adapting to the glazing needs of casserole blanks of various sizes. The glazing bell jar 302 adopts a bidirectional glazing semi-enclosed arc structure, which can effectively block glaze splashing and avoid contaminating the workshop environment and other parts of the equipment. At the same time, the protective bottom cover 303 provides a stable mounting base for the heating plate 304. Its bolt connection structure with the heating plate 304 can evenly diffuse the heat generated by the heating plate 304 into the glazing space, accurately control the constant temperature of the casserole blank during the glazing process, stabilize the flow and viscosity of the glaze, and reduce glaze defects such as dripping, glaze shrinkage, and pinholes. The top guide ring 310 can smoothly guide the glaze entering the glazing bell jar 302 for glazing, further improving the quality of the glazed finished product.
[0048] according to Figures 5-7 As shown, a second pump 305 is bolted to one side of the outer wall of a sliding bracket 301. The output end of the second pump 305 is connected to a first glazing pipe 307. A glazing bracket 306 is fixedly connected to the outer surface of the glazing bell jar 302. A glazing nozzle 308 is provided at the top of the glazing bracket 306. The other end of the first glazing pipe 307 is connected to one side of the outer wall of the glazing nozzle 308.
[0049] In this embodiment of the invention, the second pump 305 firstly provides stable power for the glazing process. Its bolted connection with the sliding bracket 301 ensures a secure installation and facilitates later maintenance and repair. It can precisely control the glazing pressure and flow rate to adapt to the glazing requirements of different sized casseroles. The first glazing pipe 307 stably delivers the constant-pressure glaze output from the second pump 305 to the glaze outlet 308. The glazing pipe is made of corrosion-resistant food-grade material, which will not contaminate the glaze and has excellent aging resistance, making it suitable for long-term continuous production. Meanwhile, the glazing bracket 306 provides precise positioning support for the glaze outlet 308, achieving full-area coverage of glazing on the outer wall and the inner wall.
[0050] according to Figures 5-7 As shown, the input end of the second pump 305 is connected to the second glazing pipe 309, and the other end of the second glazing pipe 309 is connected to one side of the outer wall of the glaze storage tank 113.
[0051] In this embodiment of the invention, the second glazing pipe 309 first connects the glaze storage tank 113 to the input end of the second pump 305, forming a complete glaze liquid circulation supply loop. This ensures a continuous and stable supply of glaze liquid during the glazing process, avoiding incomplete glazing caused by glaze interruption. This direct-connection circulation supply structure, combined with the dual-tank connection design of the glaze storage tank 113, ensures that the pressure and concentration of the glaze liquid supply remain stable, reduces the glazing quality differences between batches, improves batch consistency in large-scale production, and realizes closed-loop recycling of glaze liquid, significantly reducing glaze material loss and production costs.
[0052] During use, after the system is powered on and initialized, the clay pot conveying component 100 starts the operation process first. The motor 108 on the outer wall fixing plate 107 of the crossbar 103 receives a control signal. After being reduced in speed by the reducer 109, the motor 108 drives the roller 110 at its power output end to rotate. Through the belt 111, the rotating shaft 104 and the roller 105 rotate synchronously, causing multiple sets of rubber rings 106 on the outer surface of the roller 105 to form a continuously rotating conveying surface, smoothly conveying the ceramic clay pot blank to be glazed to the work station area of the glazing temperature control component 300. The clay pot blank is then placed flat on the rubber ring conveying surface with its opening facing down before entering the glazing chamber. At one side of the workstation of the glaze 302, the second pump 305 on the outer wall of the sliding support 301 is started, drawing the prepared glaze liquid from the glaze storage tank 113 through the second glazing pipe 309. The glaze liquid is then transported through the first glazing pipe 307 to the glaze outlet 308 on the glazing support 306. The guide ring 310 at the top of the glazing bell 302 smoothly guides the glaze liquid entering the bell 302 to the glaze outlet 308. The glaze liquid is then evenly output to the clay pot body through the glaze outlet 308, completing one section of the outer wall glazing. During the glazing process, excess glaze liquid falls back into the two connected glaze storage tanks 113 below through the gaps between the rubber rings 106 for recycling. The heating plate 304 on the bottom protective cover 303 of the bell jar 302 operates at a constant temperature, precisely controlling the temperature of the clay pot blank during the glazing process and stabilizing the viscosity of the glaze. After one stage of glazing is completed, the clay pot blank is transferred to the middle position of the glazing bell jar 302 via the rubber ring 106. At this time, the clay pot control component 200 starts the flipping second-stage glazing process. The multi-joint robotic arm on the top of the base 201 receives the control command and, through the coordinated rotation of the first arm segment 202, the second arm segment 203, and the third arm segment 204, precisely attaches the suction cup 206 at the end of the execution arm segment 205 to the outer bottom surface of the clay pot blank. Subsequently, the outer wall of the third arm segment 204... The first pump 207 is started, and the air between the suction cup 206 and the clay pot blank is drawn out through the first control pipe 208 to form a negative pressure, which firmly adsorbs and fixes the clay pot blank. At the same time, the excess glaze liquid accumulated in a section of the deep cavity of the clay pot after glazing is drawn out through the first control pipe 208. The extracted excess glaze is transported back to the glaze storage tank 113 through the second control pipe 209 to complete the recycling. After the excess glaze is extracted, the multi-joint robotic arm drives the clay pot blank to flip through the execution arm section 205, so that the inner cavity of the clay pot is facing upward. Then, the flipped clay pot blank is placed back smoothly on the transmission surface of the rubber ring 106. The first pump 207 stops the negative pressure adsorption, and the robotic arm resets to the standby position.After being flipped, the clay pot blank is transferred to the other side of the glazing bell jar 302 via the rubber ring 106. The inner wall of the flipped clay pot is then glazed in two stages, achieving uniform coverage of the entire inner and outer walls of the clay pot. During the glazing process, the heating plate 304 continuously maintains a constant temperature for the blank. Excess glaze also falls back into the glaze storage tank 113 for recycling. Throughout the process, the clay pot transfer component 100 isolates dust and impurities through the outer shell 112 and transports the blank through the rubber ring 106. The clay pot control component 200 achieves damage-free flipping and closed-loop recycling of excess glaze through the precise movement of the multi-joint arm. The glazing temperature control component 300 prevents glaze splashing through the closed glazing bell jar 302 and achieves constant temperature control throughout the process through the integrated heating plate 304. The three components work together in a systematic and coordinated manner to achieve automated glazing and full-process quality control, enabling uniform glazing of the entire area of the deep cavity blank of the ceramic clay pot, efficient and continuous production, and closed-loop recycling of glaze. This meets the stringent requirements of the daily ceramics industry for high-quality, low-loss, and high-stability glazing in large-scale production.
