Description

Technical Field

[0001] This invention relates to the field of ceramic glazing tools, and more particularly to an immersion glazing device for ceramic processing. Background Technology

[0002] Ceramic glazing is an important process in ceramic production and processing. The glazing process mainly involves immersing the ceramic blank completely or partially into the glaze before firing. The glaze layer adheres evenly to the surface of the blank by relying on its own adsorption force. After drying and firing, a smooth and dense glaze protective layer is formed, which not only enhances the appearance of ceramic products, but also improves the ceramic's waterproof, corrosion-resistant, and wear-resistant properties. At present, the glazing process is widely used in the mass production and processing of daily-use ceramics, art ceramics, and industrial ceramics due to its simple operation and good glaze forming effect.

[0003] Currently, traditional immersion glazing equipment on the market mainly consists of a conveyor frame, simple clamping fixtures, a fixed immersion table, and a common glaze storage tank. Its working principle mainly relies on the conveying mechanism to transport the ceramic blank to the processing station, using rigid clamps to hold and fix the ceramic blank, and using a lifting cylinder to drive the workpiece vertically downward to immerse it in the glaze liquid. After immersion, the workpiece is lifted to complete the glazing operation. The glaze tank is generally equipped with a single stirring shaft to achieve simple stirring, thereby completing the continuous immersion glazing process. This type of traditional equipment has a simple structure and low production cost, and can meet the basic needs of large-scale ceramic immersion glazing production. However, it still has many defects in actual use.

[0004] First, most existing glazing equipment uses a fixed clamping structure, which cannot adjust the clamping angle. This results in a single glazing posture for the workpiece, making it impossible to adjust the tilt angle according to the ceramic's shape. This makes it easy for corners and recesses of irregularly shaped ceramic workpieces to become glazing dead zones. The workpiece remains stationary inside the glaze, preventing the glaze from evenly coating the workpiece surface. This leads to uneven glaze thickness, localized glaze leakage, and glaze buildup, significantly reducing the yield of finished ceramic products. Second, traditional glaze tanks often use a single-layer tank structure. When the ambient temperature is low, the glaze's fluidity decreases, making it prone to condensation and skin formation. The glaze tank typically only has a single stirring rod, resulting in limited stirring direction and dead zones at the bottom and corners. This easily leads to glaze sedimentation and stratification, uneven glaze concentration, and consequently, significant color differences and poor stability in different batches of workpieces. Furthermore, traditional equipment lacks dedicated glaze cleaning components. Over time, a hardened film, floating impurities, and metallic contaminants form on the surface of the glaze. These impurities cannot be cleaned promptly and mix into the glaze, causing particle defects on the surface of later-processed workpieces. This severely affects the appearance quality of ceramics and is detrimental to long-term continuous production. Therefore, improvements are needed to address these issues. Summary of the Invention

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1: See Figures 1 to 14This invention discloses a ceramic processing dip-glazing device, comprising a CNC machine housing 1.

The second linear motor 4 is also equipped with a positioning mechanism for moving the workpieces. This positioning mechanism facilitates clamping, positioning, angle adjustment, and glazing posture control of the ceramic workpieces. Furthermore, a double-layered glaze tank 3 is installed inside the CNC machine housing 1. This double-layered structure facilitates heat insulation, glaze storage, and isolation from external dust. Impurities; A flow mechanism is installed on the glaze pool 3 to prevent glaze from solidifying. The flow mechanism facilitates continuous stirring of the glaze liquid and temperature control, preventing glaze sedimentation and solidification; The feeding mechanism includes a three-axis linear motor 6 installed on the top surface inside the CNC machine housing 1. The three-axis linear motor 6 facilitates three-axis spatial displacement and flexible adjustment of the gripping position; A first electric push rod 7 is installed at the output end of the three-axis linear motor 6. The first electric push rod 7 facilitates vertical extension and retraction, controlling the lifting height of the workpiece (it can be mechanically gripped in conjunction with the conveyor belt 5. At this time, only the first electric push rod 7 needs to extend, and its height is sufficient to place the workpiece on the rubber suction cup 21. The workpiece can also be manually picked up, and then the four-jaw caliper 8 clamps and fixes it, and the three-axis linear motor... The linear motor 6 drives the first electric push rod 7 to descend, and at the same time, the first electric push rod 7 extends downward to immerse the workpiece into the glaze pool 3. The output end of the first electric push rod 7 is equipped with a detachable and replaceable four-jaw caliper 8. The detachable four-jaw caliper 8 is easy to adapt to different specifications of ceramic workpieces and is easy to disassemble and replace. The four-jaw caliper 8 has two types: external clamp and internal support. The external clamp can be used to realize automatic loading and unloading, while the internal support can be used for glazing only on the outer surface of the workpiece. The bottom of the inner side of the caliper 8 is equipped with a serrated rubber pad 9. The serrated rubber pad 9 can increase the clamping friction and prevent the workpiece from slipping. The rubber pad 9 is coated with an anti-stick layer. The anti-stick layer can prevent the glaze from sticking to the caliper, reduce impurities, and facilitate cleaning.

[0038] Example 2: The technical solution is basically the same as that of Example 1, except that, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, the positioning mechanism includes a first mounting plate 10 mounted on the second linear motor 4. The first mounting plate 10 facilitates the support and fixation of the various components of the positioning mechanism, ensuring installation stability. A rotating base 11 is hinged to the first mounting plate 10, which facilitates overall angle deflection and adjustment of the workpiece glazing tilt angle. Two coaxially connected positioning arms 13 are rotatably connected to the rotating base 11, and two synchronously driven second electric actuators 12 are hinged to the first mounting plate 10. The two sets of synchronous second electric actuators 12 facilitate synchronous pushing and pulling of the rotating base 11, achieving precise angle adjustment. The output ends of the two second electric actuators 12 are respectively hinged to both sides of the rotating base 11. The double-sided hinged installation method facilitates the support of the rotating base 11. The force is even, preventing deflection and jamming; the rotating base 11 has an installation slot, which facilitates the concealment of the drive components, saving space and providing dust protection; a first DC motor 14 is installed in the installation slot, which provides stable power for the rotation of the positioning arm 13; the output end of the first DC motor 14 is connected to a first gear 15 via a coupling, which facilitates power transmission through a meshing structure; a second gear 16 is installed on the rotating shaft of the two positioning arms 13, which meshes with the first gear 15, facilitating precise control of the opening and closing angle of the positioning arms 13, providing strong transmission stability, and the second gear 16 has a larger diameter than the first gear 15, achieving a deceleration effect; the positioning arm 13 has an internal... A third electric actuator 17 and four guide rods are installed. The third electric actuator 17 facilitates telescopic pushing and adjusting the workpiece clamping distance. The four guide rods are distributed around the periphery of the third electric actuator 17, ensuring smooth telescopic movement and preventing offset and swaying. A base plate 18 is installed at the output end of the third electric actuator 17, which supports the rear adsorption assembly and achieves structural connection and fixation. One end of each of the four guide rods is fixedly connected to the base plate 18, which enhances structural rigidity and reduces deformation. A hollow mounting base 19 is installed on the other side of the base plate 18, which facilitates the internal installation of transmission and pneumatic components and optimizes the layout. The other side of the mounting base 19... The mounting base 19 is equipped with a flow guide base 26, which facilitates the drainage of excess glaze and prevents glaze accumulation. A hopper 27 is installed around the flow guide base 26 to collect dripping glaze and enable glaze recycling. A flexible air tube 23 is installed on one side of the mounting base 19 to accommodate rotational deformation and prevent bending or breakage. A motor 22 and a rigid air tube 25 are installed on the inner wall of the mounting base 19. The motor 22 provides power for the rotation of the suction cup, and the rigid air tube 25 facilitates the stable transmission of negative pressure airflow. One end of the flexible air tube 23 and one end of the rigid air tube 25 are rotatably connected through a sealed rotary joint, which facilitates airflow connectivity during rotation.The output end of motor 22 is equipped with a third gear 24 via a coupling. The third gear 24 facilitates the transmission of power from motor 22, enabling meshing transmission. A gear ring is installed around the periphery of rigid air tube 25, meshing with the third gear 24. This gear ring facilitates the overall rotation of rigid air tube 25, resulting in high transmission torque and stability. One end of rigid air tube 25 is fixedly connected to a rotating arm 20, which allows for extending the transmission distance and adjusting the suction cup's adsorption position. One end of the rotating arm 20 is equipped with a rubber suction cup 21 for adsorbing and fixing ceramic workpieces. The rubber suction cup 21 facilitates negative pressure adsorption of ceramic workpieces, avoiding damage caused by rigid clamping. The rubber suction cup 21 is rotatably mounted on the mounting base 19. This rotatable mounting structure allows for multi-angle rotation and glazing of the workpiece, improving the uniformity of glazing.

[0039] Example 3: The technical solution is basically the same as that of Example 1, except that, as Figure 9 , Figure 10 , Figure 11As shown, the unloading mechanism includes a receiving plate 28 mounted on the first linear motor 2. The receiving plate 28 facilitates the receiving of ceramic workpieces after glazing, completing the unloading and storage. Multiple through grooves for glazing are formed on the receiving plate 28, allowing excess glaze to drip quickly back into the glaze pool 3, reducing glaze waste. Two synchronously driven fourth electric actuators 29 are mounted on the bottom surface of one end of the receiving plate 28. These actuators vertically push the cleaning component, controlling the cleaning height to adapt to the liquid level in the glaze pool 3. A second mounting plate 30 is mounted on the output end of the fourth electric actuators 29, facilitating the fixing of the cleaning component and ensuring the integrity of the cleaning structure. A useful... The cleaning component for cleaning the condensate layer on the surface of the glaze pool 3 facilitates the scraping of scum and hardened glaze from the surface, ensuring the quality of the glaze. The cleaning component includes a third mounting plate 31 hinged to the bottom of the second mounting plate 30. The hinged third mounting plate 31 allows for adaptive angle adjustment to conform to the glaze surface of the pool 3. A U-shaped filter frame 32 is fixed to the bottom of the third mounting plate 31, facilitating the removal and filtering of surface impurities and solidified glaze blocks. Two symmetrically arranged guide plates 33 are fixed to the bottom of the filter frame 32, guiding its tilt for better removal of condensate from the surface of the glaze pool 3. Multiple magnets 34 are equidistantly installed on both sides of the third mounting plate 31, facilitating the attraction of... The glaze is purified by removing metallic impurities; multiple return springs 35 are equidistantly installed between the second mounting plate 30 and the third mounting plate 31; the flow mechanism includes a heating rod 42 installed in the jacket of the glaze tank 3, which facilitates constant temperature heating of the glaze and prevents solidification of the glaze in low-temperature environments; two sensors 43 installed inside the glaze tank 3, which facilitate real-time monitoring of the glaze temperature and concentration parameters for intelligent control; a second DC motor 36 installed on the bottom surface of the glaze tank 3, which provides vertical stirring power; and a third DC motor 38 and a fourth DC motor 40 installed on both sides of the glaze tank 3, which facilitate multi-angle stirring power. To eliminate dead zones in the stirring process, the output end of the second DC motor 36 is vertically mounted with a first stirring blade 37 via a coupling. The vertically arranged first stirring blade 37 facilitates stirring of the bottom glaze liquid and prevents sedimentation at the bottom. The first stirring blade 37 is rotatably connected to the center of the inner bottom of the glaze tank 3. The center mounting method facilitates even stirring of the glaze liquid in the central area of ​​the glaze tank 3. The output end of the third DC motor 38 is inclined downwards via a coupling with a second stirring blade 39. The inclined downwards second stirring blade 39 facilitates stirring of the lower layer of glaze liquid on the side and prevents sedimentation at the edges and corners. The output end of the fourth DC motor 40 is inclined upwards via a coupling with a third stirring blade 41. The inclined upwards third stirring blade 41 facilitates churning of the upper layer of glaze liquid and prevents the surface from solidifying.A liquid level sensor is installed on the inner wall of the glaze tank 3, which facilitates real-time monitoring of the glaze liquid level and enables automatic replenishment reminders. Two feeding pipes 44 are installed on one side of the glaze tank 3, allowing for rapid replenishment of the glaze liquid or supplementation of raw materials when the glaze concentration is insufficient, thus increasing feeding efficiency. The output end of the feeding pipes 44 faces the bottom of the glaze tank 3, and the bottom discharge method helps reduce glaze liquid bubbles and avoids surface glaze splashing and disturbance.

[0040] Working principle: In this embodiment, the present invention also proposes a method for using an immersion glazing device for ceramic processing, including the following steps:

[0041] Step one, the initial stage of equipment use, requires pre-start checks. These checks include the lubrication status of all moving parts, the glaze level and concentration in the glaze tank 3, and ensuring all parameters meet the requirements for ceramic glazing. Then, the entire equipment is started via the CNC machine housing 1, putting the internal electrical control system, linear motors, and related actuators into standby mode, preparing for subsequent continuous processing. The CNC machine housing 1 provides sealed protection for the entire equipment and centralized electrical control integration, ensuring stability and safety during operation.

[0042] Step two: After the equipment is started, the loading stage begins. The conveyor belt 5 transports the ceramic workpieces to be processed sequentially to the window on one side of the CNC machine box 1. At this time, the loading mechanism starts to work: the three-axis linear motor 6 installed on the top surface inside the CNC machine box 1 drives the first electric push rod 7 to move directly above the workpiece. The first electric push rod 7 extends and drives the four-jaw caliper 8, which is detachably installed at its output end, to move down. After the four-jaw caliper 8 clamps the workpiece, the three-axis linear motor 6 and the first electric push rod 7 work together to lift the workpiece and transfer it to the rubber suction cup 21 of the positioning mechanism. Then, the rubber suction cup 21 uses negative pressure to fix the workpiece, and the four-jaw caliper 8 releases the workpiece, completing the automated loading operation of a single workpiece. The whole process does not require manual intervention and achieves efficient automatic loading. The serrated rubber pad 9 on the bottom inner side of the four-jaw caliper 8 can increase the clamping friction and prevent the workpiece from slipping. The anti-stick layer on the rubber pad 9 can prevent the glaze from sticking to the caliper.

[0043] Step three: After the material is loaded, the core glazing process begins. The second linear motor 4 drives the positioning mechanism mounted on it to move directly above the glaze tank 3. The positioning mechanism then adjusts the workpiece's glazing posture: two synchronously driven second electric push rods 12 hinged on the first mounting plate 10 extend and retract synchronously, pushing and pulling the rotating base 11 to achieve angular deflection and adjust the workpiece's glazing tilt angle; the first DC motor 14 inside the rotating base 11 drives the first gear 15 to rotate through a coupling. The first gear 15 meshes with the second gears 16 on the rotating shafts of the two positioning arms 13, precisely controlling the opening and closing angle of the positioning arms 13. Simultaneously, the third electric push rod 17 inside the positioning arm 13 extends and retracts, working with the four guide rods on the periphery to smoothly adjust the workpiece clamping distance, ensuring the workpiece maintains a suitable glazing posture; after the posture adjustment is completed, the positioning mechanism... The ceramic workpiece is lowered and immersed in the glaze liquid in the glaze pool 3. At this time, the motor 22 drives the third gear 24 to rotate through the coupling. The third gear 24 meshes with the toothed ring on the side of the rigid air pipe 25, which drives the rigid air pipe 25, the rotating arm 20 and the rubber suction cup 21 to rotate slowly, thereby driving the workpiece to rotate at a uniform speed, so that the glaze liquid is evenly attached to the surface of the workpiece. During the processing, the flow mechanism on the glaze pool 3 runs continuously. The heating rod 42 in the jacket of the glaze pool 3 maintains the constant temperature of the glaze liquid and prevents low-temperature solidification. The second DC motor 36 on the bottom of the glaze pool 3 drives the first stirring blade 37 to rotate, stirring the glaze liquid at the bottom to prevent sedimentation. The third DC motor 38 and the fourth DC motor 40 on both sides of the glaze pool 3 drive the second stirring blade 39 and the third stirring blade 41 respectively to stir the glaze liquid from different angles, eliminate the stirring dead corners and avoid the glaze liquid from settling and solidifying.

[0044] Step four: After the glazing process is completed, the workpiece enters the unloading and glazing stage. The positioning mechanism lifts the glazed workpiece out of the glaze pool 3. The first linear motor 2 drives the unloading mechanism mounted on it to move below the workpiece. The rubber suction cup 21 breaks the negative pressure and releases the workpiece. The three-axis linear motor 6 drives the first electric push rod 7 and the four-jaw caliper 8 to clamp the workpiece and place it stably on the receiving plate 28. Excess glaze on the surface of the workpiece drips quickly through multiple through grooves on the receiving plate 28 and flows back into the glaze pool 3, reducing glaze waste. At the same time, two synchronously driven fourth electric push rods 29 extend from the bottom of one end of the receiving plate 28, pushing the second The mounting plate 30 and the bottom cleaning components move down, causing the U-shaped filter frame 32 at the bottom of the third mounting plate 31 to fit against the glaze surface. The first linear motor 2 drives the feeding mechanism to move laterally as a whole. The filter frame 32 removes the scum and condensed glaze from the surface of the glaze. Multiple magnets 34 on both sides of the third mounting plate 31 attract and remove metal impurities in the glaze, completing the cleaning work on the surface of the glaze pool 3 and ensuring the quality of the subsequent glaze. The reset spring 35 between the second mounting plate 30 and the third mounting plate 31 can assist the cleaning components in adapting to the angle of the glaze pool 3, and the guide plate 33 at the bottom of the filter frame 32 can guide the filter frame 32 to better remove condensate.

[0045] Step 5: After the material feeding and glaze tank cleaning are completed, the equipment enters a continuous cycle operation state, repeating the above steps of feeding, glazing, feeding, glazing, and glaze tank cleaning. The conveyor belt 5 continuously transports the workpieces to be processed. The feeding mechanism, positioning mechanism, flow mechanism, and feeding mechanism work together to realize the continuous automated glazing process of ceramic workpieces until all workpieces to be processed have completed the glazing process. After processing, the power of the CNC machine box 1 is turned off, and all mechanisms are stopped. The various parts of the equipment can be cleaned and maintained, and the glaze liquid in the glaze tank 3 is replenished to prepare for the next use. The two feeding pipes 44 on one side of the glaze tank 3 can be used to quickly replenish the glaze liquid or adjust the glaze liquid concentration. The output end of the feeding pipe 44 faces the bottom of the glaze tank 3 to reduce the generation of glaze liquid bubbles.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
