Description

Technical Field

[0001] This invention relates to the field of energy-saving ceramic production technology, specifically to a molding machine for industrial ceramic production. Background Technology

[0002] The molding machine for industrial ceramics production is a specialized piece of equipment for preparing industrial ceramic blanks. It uses a hydraulically driven structure in conjunction with upper and lower matching molds to press and mold dry ceramic powder. It is used for the mass production of various industrial ceramic products such as structural ceramics. The process involves filling the lower mold cavity with pre-treated spray-granulated ceramic powder, then leveling the powder at the top of the mold using a scraping mechanism. Subsequently, the upper mold is driven downward by a hydraulic mechanism to apply constant high pressure to the ceramic powder in the cavity, causing the loose powder particles to adhere tightly and be compacted to form a ceramic green blank with a complete structure and uniform specifications.

[0003] Current industrial ceramic molding machines use a scraper structure to remove excess powder from the top of the mold cavity after powder filling, making the powder surface relatively flat. However, during long-term high-frequency scraping operations, the scraper structure is prone to wear and local defects. Moreover, the wear locations are random and hidden, making it difficult to inspect and replace in a timely manner. The worn scraper structure cannot effectively scrape and flatten the powder in the corresponding location, resulting in local bulges of powder in the corresponding area of ​​the mold cavity. This causes the powder surface to be uneven, thus reducing product quality and making it difficult to meet environmental protection and energy-saving requirements.

[0004] To address the above issues, a molding machine for industrial ceramic production is proposed. Summary of the Invention

[0020] By setting up the array of elastic pre-compression components, the ceramic powder in the mold can be elastically pre-compressed in sections. The sedimentation difference is generated by the independent floating of each pre-compression frame, which can intuitively reflect the density stratification and particle segregation problems inside the powder, providing accurate data for subsequent uniformity correction and improving the basis for uniformity of the green body density.

[0021] By cooperating with the extending uniform material component, the snap-fit ​​component, and the drive component, the uniform material rod can be automatically extended and inserted into the powder when the powder sedimentation exceeds the standard. With the small forward and reverse rotation of the motor, the powder is disturbed and redistributed, eliminating uneven distribution defects from the inside and reducing delamination and cracking defects in green sintering.

[0022] By linking the translation and lifting components with the vision sensor, the three-dimensional contour re-inspection can be completed step by step after the leveling and pre-pressing processes, forming a closed-loop detection process for powder leveling and pre-pressing settlement. The entire process automatically identifies defects, eliminating the errors and lag of manual visual judgment.

[0023] By integrating automatic defect identification, automatic correction, and abnormal alarm functions, the system can reduce the flow of defective blanks into the high-temperature sintering process, lower sintering energy consumption and raw material loss, reduce the frequency of manual maintenance, and achieve the energy-saving and environmentally friendly processing requirements of ceramic production while stabilizing the yield of finished products.

[0033] 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.

[0034] like Figures 1-3 and Figure 5 As shown, a molding machine for industrial ceramic production includes a base 1, which is used to support and fix various components. A controller is fixedly installed on one side of the base 1, which can control various electrical components. The controller is existing technology and is not shown in the figure. A molding assembly 2 is provided on the top of the base 1. The molding assembly 2 performs dry pressing molding of ceramic powder to prepare green blanks.

[0035] The molding assembly 2 includes guide rods 21 fixedly connected to the four corners of the top of the base 1. One end of the guide rod 21 is fixedly connected to a mounting base 22. A hydraulic cylinder 23 is fixedly installed inside the mounting base 22. The movable end of the hydraulic cylinder 23 is fixedly connected to a lifting seat 24. The bottom of the lifting seat 24 is fixedly connected to an upper mold body 25. The top of the base 1 is fixedly connected to a lower mold body 26. A material groove 27 is opened on the top of the lower mold body 26. A crossbar 28 is fixedly connected inside the base 1. A fixing column 29 is fixedly connected to the top of the crossbar 28. The fixing column 29 is located inside the material groove 27. The upper surface of the top of the fixing column 29 is at the same level as the upper surface of the top of the lower mold body 26, which can form an annular cavity for ceramic blank production. At the same time, it ensures that the material is swept along during the leveling operation and avoids material steps in the central area.

[0036] To address the technical problem of wear and localized defects in the scraping structure, which leads to substandard surface smoothness of the powder and consequently reduces product quality, the following preferred technical solution is provided:

[0037] like Figure 1 and Figures 3-6 As shown, a translation component 3 is provided on one side of the molding component 2. A lifting component 4 is provided inside the translation component 3. A vision sensor 5 for detecting the flatness of the powder surface and the amount of pre-compression settlement is fixedly installed inside the translation component 3. The vision sensor 5 is a high-precision three-dimensional vision inspection camera that can collect the height contour data of the top surface of the powder. Two scraping components 7 are fixedly connected to one side of the dynamic conversion component 6. The dynamic conversion component 6 drives the two scraping components 7 to rotate and switch positions, which can realize the automatic replacement of the worn scraper with the spare scraper. An ejector component 8 is provided inside the base 1. The ejector component 8 can smoothly eject the molded ceramic green body from the lower mold structure.

[0038] In use, the controller enables the external feeding mechanism to inject ceramic powder into the lower mold structure of the molding component 2. Then, the controller enables the translation component 3 to extend, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to move synchronously, so that the scraping component 7 scrapes away and flattens the ceramic powder that is higher than the top surface of the lower mold structure.

[0039] When the translation component 3 moves the vision sensor 5 to directly above the lower mold structure in the molding component 2, the controller stops the translation component 3 from extending and performs a vision inspection operation. The vision sensor 5 performs a three-dimensional contour scan on the top surface of the ceramic powder in the lower mold structure. Due to long-term scraping operation, the scraping component 7 will experience local wear.

[0040] When the vision sensor 5 detects that the ceramic powder surface is flat, the subsequent pre-pressing process continues. When the vision sensor 5 detects local protrusions in the ceramic powder, the controller causes the lifting assembly 4 to drive the dynamic conversion assembly 6 and the scraping assembly 7 to rise synchronously. Then, the controller causes the dynamic conversion assembly 6 to drive the two scraping assemblies 7 to rotate 180° to switch, allowing the spare scraping assembly 7 to replace the worn scraping assembly 7. Afterwards, the controller causes the translation assembly 3 to retract, causing the lifting assembly 4, vision sensor 5, dynamic conversion assembly 6, and scraping assembly 7 to move synchronously for reset. Then, the lifting assembly... Component 4 drives the dynamic conversion component 6 and the scraping component 7 to descend synchronously, so that the bottom surface of the spare scraping component 7 is in contact with the top surface of the lower mold structure. Then, through the controller, the translation component 3 extends, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to move synchronously again to perform secondary leveling and inspection. When the vision sensor 5 detects that the flatness of the ceramic powder has returned to the qualified level, the subsequent process continues. When the vision sensor 5 detects that the ceramic powder is still uneven, the controller triggers the alarm to remind the user to perform maintenance. The alarm is existing technology and is not shown in the figure.

[0041] Through the automatic switching process of the scraper assembly 7, scraping defects can be automatically identified and a spare scraper can be switched to ensure the consistency of the surface leveling accuracy of the powder. Compared with the single fixed scraper in the existing technology, which requires manual shutdown for replacement after wear, it can reduce downtime for changing parts and improve continuous production efficiency. At the same time, by reducing the scrap rate of blanks caused by poor scraping, energy-saving and environmental protection benefits of ceramic production can be achieved.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, the translation component 3 includes a first electric push rod 31 installed inside the lower mold body 26. The first electric push rod 31 is a multi-section telescopic electric push rod, which can provide a large stroke within a limited installation space to meet the requirements of multi-station translation switching. The movable end of the first electric push rod 31 is fixedly connected to a push rod 32. One side of the push rod 32 is fixedly connected to two first limit rods 33. Both first limit rods 33 are slidably connected to the lower mold body 26. One side of the push rod 32 is fixedly connected to an L-shaped translation plate 34. The vision sensor 5 is fixedly installed inside the L-shaped translation plate 34. The top of the lower mold body 26 is fixedly connected to two slide rails 35. One side of each slide rail 35 is slidably connected to a slider 36. One side of each slider 36 is fixedly connected to a push plate 37. One side of the push plate 37 is fixedly connected to a connecting frame 38. The connecting frame 38 is fixedly connected to the L-shaped translation plate 34.

[0043] like Figure 4 and Figure 5As shown, the lifting assembly 4 includes a second electric push rod 41 installed inside the L-shaped translation plate 34. The movable end of the second electric push rod 41 is fixedly connected to a U-shaped lifting plate 42. Two slide rods 43 are fixedly connected to the top of the U-shaped lifting plate 42, and both slide rods 43 are slidably connected to the L-shaped translation plate 34.

[0044] like Figure 4 As shown, the dynamic conversion component 6 includes a servo motor 61 fixedly installed on one side of the U-shaped lifting plate 42. The servo motor 61 has a self-locking function. A rotating shaft 62 is rotatably connected inside the U-shaped lifting plate 42. The output end of the servo motor 61 is fixedly connected to one end of the rotating shaft 62.

[0045] like Figure 4 and Figure 5 As shown, the scraping assembly 7 includes two arc-shaped fixing plates 71 that are fixedly connected to the outer wall of the rotating shaft 62. An inclined push plate 72 is fixedly connected to one side of each of the two arc-shaped fixing plates 71. The inclined push plate 72 is made of wear-resistant polyurethane material, which can combine good wear resistance and elasticity, effectively scrape the powder without scratching the mold surface. Bolts 73 are threaded to both ends of the two arc-shaped fixing plates 71. The bolts 73 are threaded to the rotating shaft 62. By rotating the bolts 73, the arc-shaped fixing plates 71 and the inclined push plate 72 can be disassembled and replaced, thereby realizing rapid maintenance and precision restoration after the inclined push plate 72 is worn.

[0046] like Figure 3 As shown, the top material assembly 8 includes a third electric push rod 81 fixedly installed in the base 1. The movable end of the third electric push rod 81 is fixedly connected to a lifting sleeve 82. The lifting sleeve 82 is slidably connected to the lower mold body 26. The top of the lifting sleeve 82 is fixedly connected to a top material plate 83. The top material plate 83 is slidably connected to the lower mold body 26 and the fixed column 29 respectively.

[0047] like Figure 1 and Figures 3-6 As shown, during use, the controller enables the external feeding mechanism to inject ceramic powder into the lower mold body 26. Then, the controller causes the movable end of the first electric push rod 31 to extend, driving the push rod 32, the two first limit rods 33, the L-shaped translation plate 34, the connecting frame 38, the push plate 37, and the two sliders 36 to move. This causes the sliders 36 to slide on the slide rail 35, and the first limit rods 33 to slide inside the lower mold body 26. This causes the second electric push rod 41, the U-shaped lifting plate 42, the vision sensor 5, the rotating shaft 62, and the inclined push plate 72 to move synchronously, so that the inclined push plate 72 scrapes and flattens the ceramic powder that is higher than the top surface of the lower mold body 26.

[0048] When the first electric push rod 31 drives the vision sensor 5 to move directly above the material trough 27, the controller stops the first electric push rod 31 from extending and performs a vision detection operation. The vision sensor 5 performs a three-dimensional contour scan of the top surface of the ceramic powder in the material trough 27. Due to long-term scraping operation, the bottom of the inclined push plate 72 will experience local wear.

[0049] When the vision sensor 5 detects that the surface of the ceramic powder is flat, the subsequent pre-pressing process continues. When the vision sensor 5 detects that there are local protrusions in the ceramic powder, the controller causes the second electric push rod 41 to drive the U-shaped lifting plate 42, the rotating shaft 62, and the inclined push plate 72 to rise synchronously. Then, the controller causes the servo motor 61 to drive the rotating shaft 62 and the two inclined push plates 72 to rotate 180° to switch, so that the spare inclined push plate 72 replaces the worn inclined push plate 72. After that, the controller causes the movable end of the first electric push rod 31 to retract, driving the U-shaped lifting plate 42, the vision sensor 5, and the rotating shaft... The rotating shaft 62 and the inclined push plate 72 move synchronously to reset. Then, the second electric push rod 41 drives the rotating shaft 62 and the inclined push plate 72 to descend synchronously, so that the bottom surface of the spare inclined push plate 72 is in contact with the top surface of the lower mold body 26. Then, the controller causes the first electric push rod 31 to extend, driving the inclined push plate 72 to move synchronously again to perform secondary leveling and inspection. When the vision sensor 5 detects that the flatness of the ceramic powder has returned to the qualified level, the subsequent process continues. When the vision sensor 5 detects that the ceramic powder is still uneven, the controller causes the alarm to sound to remind the user to check and repair.

[0050] The automatic switching process of the inclined push plate 72 can automatically identify scraping defects and switch to a spare scraper, ensuring the consistency of the surface leveling accuracy of the powder. Compared with the single fixed scraper in the existing technology, which requires manual shutdown for replacement after wear, it can reduce downtime for changing parts and improve continuous production efficiency. At the same time, by reducing the scrap rate of blanks caused by poor scraping, it can achieve energy-saving and environmental protection benefits in ceramic production.

[0051] To address the technical challenge of detecting uneven distribution within ceramic powder, the following preferred technical solution is provided:

[0052] like Figures 5-8 As shown, the translation component 3 is equipped with a driving component 9, the driving component 9 is equipped with an array elastic preloading component 10 for partition elastic preloading and settlement detection, the array elastic preloading component 10 is equipped with an extension uniform material component 20 for disturbing and uniformizing the material, and the extension uniform material component 20 is equipped with a snap-fit ​​component 30.

[0053] After the surface flatness detection is completed, the controller causes the translation component 3 to extend, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to move synchronously again, causing the drive component 9, array elastic pre-compression component 10 and extension uniform component 20 to move synchronously to perform pre-compression operation. When the array elastic pre-compression component 10 is directly above the lower mold structure, the controller causes the other output end of the drive component 9 to rotate in the forward direction, driving the array elastic pre-compression component 10 to descend synchronously, realizing the zoned elastic pre-compression of ceramic powder. Then, the controller causes the other output end of the drive component 9 to rotate in the reverse direction, driving the array elastic pre-compression component 10 to rise synchronously for reset. Subsequently, the controller causes the translation component 3 to retract, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to move synchronously, causing the vision sensor 5 to move to directly above the lower mold structure to perform pre-compression settlement detection operation. Because ceramic powder will have depth density stratification and particle segregation during the filling process, even if the surface is leveled, it is not easy to eliminate the uneven distribution of internal materials.

[0054] When the vision sensor 5 detects that the settling difference of the pre-compressed ceramic powder in each area is within the qualified range and the internal material distribution is uniform, the controller causes the translation component 3 to extend, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to move synchronously again, so that the translation component 3 moves out of the avoidance position of the molding component 2 that needs to be molded. Then, the controller causes the hydraulic structure in the molding component 2 to descend, so that the upper mold structure in the molding component 2 cooperates with the lower mold structure to formally mold the ceramic powder, thereby realizing the dry pressing of the ceramic green body. After that, the controller causes the ejector component 8 to eject the molded ceramic powder out of the lower mold structure. Then, the controller causes the translation component 3 to retract, driving the lifting component 4, vision sensor 5, dynamic conversion component 6 and scraping component 7 to reset synchronously, and push out the ejected ceramic green body for unloading. Then, the controller causes the ejector component 8 to descend and reset, and then the powder is refilled to start the next molding production cycle.

[0055] When the vision sensor 5 detects that the pre-compressed ceramic powder has excessive sedimentation difference and uneven internal distribution, the controller extends the translation component 3, positioning the array elastic pre-compressing component 10 directly above the lower mold structure. Then, the controller releases the locking component 30 from the array elastic pre-compressing component 10. Subsequently, the drive component 9 rotates in the opposite direction, causing the array elastic pre-compressing component 10 and the extending uniform material component 20 to rise synchronously. Through the obstruction of the drive component 9, several extending structures within the extending uniform material component 20 extend out of the array elastic pre-compressing component 10, while simultaneously extending the elastic material within the uniform material component 20... The elastic structure is compressed, and then the controller causes the snap-fit ​​component 30 to snap back into the array elastic pre-compression component 10. Then, the controller causes the other output end of the drive component 9 to rotate in the forward direction, causing the array elastic pre-compression component 10 to extend the uniform material component 20 and the snap-fit ​​component 30 to descend synchronously, so that the extended uniform material component 20 inserts into the ceramic powder a short distance. Then, the controller causes one of the output ends of the drive component 9 to rotate slowly in both directions, so that the array elastic pre-compression component 10, the extended uniform material component 20 and the snap-fit ​​component 30 rotate slowly in both directions synchronously, so as to slightly disturb and re-distribute the unevenly distributed ceramic powder inside.

[0056] After a short period of time, the controller causes the snap-fit ​​component 30 to disengage from the array elastic pre-compression component 10 again. At this time, the elastic structure inside the material uniform component 20 is reset, causing the extended structure inside the material uniform component 20 to reset again. Then, the snap-fit ​​component 30 snaps into the array elastic pre-compression component 10 again. Subsequently, the controller causes the drive component 9 to drive the array elastic pre-compression component 10 to descend synchronously again and pre-compress the ceramic powder after disturbance and uniformization. Then, the drive component 9 drives the array elastic pre-compression component 10 to reset, and the translation component 3 drives the vision sensor 5 to perform a re-inspection operation again. When the vision sensor 5 detects that the sedimentation difference of the pre-compressed ceramic powder is qualified and the uniformity meets the standard, the subsequent formal molding operation is performed. When the vision sensor 5 detects that the pre-compressed ceramic powder still has uneven distribution defects, the controller causes the alarm to sound to remind the user to perform maintenance.

[0057] The above-mentioned pre-compression testing process can automatically identify and correct defects in the uneven distribution of powder, thereby improving the uniformity of the green body density from the root. Compared with the existing technology that relies solely on vibration leveling or manual experience to judge the distribution of powder, it can reduce the risk of green body delamination and cracking, improve the yield of ceramic products, and at the same time, by reducing the number of defective green bodies entering the high-temperature sintering process, it can achieve the energy-saving and environmental protection requirements of ceramic production.

[0058] like Figures 6-8As shown, the drive assembly 9 includes a rotating cylinder 91 fixedly connected to one side of the L-shaped translation plate 34. A cylinder 92 is rotatably connected to one end of the rotating cylinder 91. A dual-axis motor 94 is fixedly installed inside the cylinder 92. The dual-axis motor 94 is a dual-output shaft servo motor, which can independently control the forward and reverse rotation of the two output shafts. The dual-axis motor 94 has a self-locking function. A connecting shaft 93 is fixedly connected to one output end of the dual-axis motor 94. The connecting shaft 93 is fixedly connected to one side of the L-shaped translation plate 34 and rotatably connected to the cylinder 92. A threaded rod 95 is fixedly connected to the other output end of the dual-axis motor 94.

[0059] The array elastic pre-compression assembly 10 includes a threaded cylinder 101 threadedly connected to the outer wall of the threaded rod 95. A lifting circular plate 102 is fixedly connected to the bottom of the threaded cylinder 101. The lifting circular plate 102 is slidably connected to the cylinder 92. Several second limiting rods 103 are slidably connected inside the lifting circular plate 102. Several pre-compression frames 105 are fixedly connected to one end of the several second limiting rods 103. The several pre-compression frames 105 form a ring array and correspond to the shape of the material trough 27. They can independently float and press down in different areas, converting the difference in loose density of different areas of powder into the difference in the settling stroke of each pre-compression frame 105. A first spring 104 is fixedly connected to one side of each of the several pre-compression frames 105. One end of the first spring 104 is fixedly connected to the bottom of the lifting circular plate 102. A first slot 106 and a second slot 107 are opened on one side of each of the several pre-compression frames 105.

[0060] The extended material distribution assembly 20 includes a U-shaped rod 201 slidably connected to the pre-compression frame 105. The U-shaped rod 201 is slidably connected to the cylinder 92. Several extended rods 202 are fixedly connected to the bottom of the U-shaped rod 201. The several extended rods 202 are all slidably connected to the pre-compression frame 105. Several second springs 203 are fixedly connected inside the pre-compression frame 105. One end of each of the several second springs 203 is fixedly connected to one side of the U-shaped rod 201.

[0061] like Figure 7 As shown, the snap-fit ​​assembly 30 includes a snap-fit ​​rod 301 slidably connected to the U-shaped rod 201. One end of the snap-fit ​​rod 301 is snapped into the first snap-fit ​​groove 106, and the other end of the snap-fit ​​rod 301 is fixedly connected to a magnet block 302. A third spring 303 is fixedly connected to one side of the magnet block 302. One end of the third spring 303 is fixedly connected to the inner wall of the U-shaped rod 201. An electromagnetic ring 304 is fixedly installed inside the cylinder 92.

[0062] like Figures 5-8As shown, after the surface flatness inspection is completed, the controller extends the first electric push rod 31, driving the second electric push rod 41, U-shaped lifting plate 42, vision sensor 5, rotating shaft 62, and inclined push plate 72 to move synchronously again. This causes the dual-axis motor 94, lifting circular plate 102, several pre-compression frames 105, and several extension rods 202 to move synchronously to perform the pre-compression operation. When the several pre-compression frames 105 are directly above the lower mold structure, the controller causes the other output end of the dual-axis motor 94 to rotate in the forward direction, driving the threaded rod 95 to rotate. Through the threaded connection between the threaded rod 95 and the threaded cylinder 101, the threaded cylinder 101, lifting circular plate 102, and several second limit rods are moved synchronously. 103. The first spring 104, several pre-compression frames 105 and several extension rods 202 descend synchronously to achieve zoned elastic pre-compression of ceramic powder. Then, through the controller, the other output end of the dual-axis motor 94 rotates in the opposite direction, driving several pre-compression frames 105 and several extension rods 202 to rise synchronously for reset. Subsequently, through the controller, the first electric push rod 31 retracts, driving the vision sensor 5 to move, so that the vision sensor 5 moves to directly above the material tank 27 to perform the pre-compression sedimentation detection operation. Because ceramic powder will exhibit depth density stratification and particle segregation during the filling process, even if the surface is scraped, it is not easy to eliminate the uneven distribution of internal materials.

[0063] When the vision sensor 5 detects that the settlement difference of the pre-compressed ceramic powder in each area is within the acceptable range and the internal material distribution is uniform, the controller extends the first electric push rod 31, causing the L-shaped translation plate 34 to move out of the clearance position required for the upper mold body 25 to perform the molding operation. Then, the controller causes the hydraulic cylinder 23 to drive the lifting seat 24 and the upper mold body 25 to move downward under the guidance of the guide rod 21, so that the upper mold body 25 cooperates with the lower mold body 26 to perform formal molding of the ceramic powder, thereby realizing the dry pressing of the ceramic green body. Afterwards, the controller extends the movable end of the third electric push rod 81. The length of the push rod drives the lifting sleeve 82 and the top plate 83 to rise synchronously, pushing the formed ceramic powder out of the material trough 27. Then, through the controller, the first electric push rod 31 retracts, driving the second electric push rod 41, vision sensor 5, rotating shaft 62, inclined push plate 72, dual-axis motor 94, lifting circular plate 102, several pre-pressing frames 105 and several extension rods 202 to reset synchronously. The pushed plate 37 pushes out the ejected ceramic blank for unloading. Then, through the controller, the third electric push rod 81 drives the top plate 83 to descend and reset. Then, the powder is refilled to start the next molding production cycle.

[0064] When the vision sensor 5 detects that the pre-compressed ceramic powder has excessive sedimentation difference and uneven internal distribution, the controller extends the first electric push rod 31, positioning several pre-compressing frames 105 directly above the lower mold structure. Then, the controller supplies current to the electromagnetic ring 304, generating magnetism that attracts several magnet blocks 302, causing the locking rod 301 to slide within the U-shaped rod 201. At this point, the locking rod 301 releases its engagement with the first locking slot 106 and compresses the third spring 303. Subsequently, the other output end of the dual-axis motor 94 rotates in the opposite direction, causing several pre-compressing frames 105, several U-shaped rods 201, and several extending rods 202 to rise synchronously. Through the obstruction of the inner wall of the cylinder 92, several extending rods 202 extend from several pre-compressing frames 105, while several second springs 20... 3 is compressed, and then the current to the electromagnetic ring 304 is canceled by the controller, so that the magnetic force of the electromagnetic ring 304 disappears. At this time, the third spring 303 resets, so that the locking rod 301 is locked with the second locking slot 107. Then, the controller makes the other output end of the dual-axis motor 94 rotate in the forward direction, driving several pre-compression frames 105, several U-shaped rods 201 and several extension rods 202 to descend synchronously, so that the extension rods 202 are inserted into the ceramic powder a short distance. Then, the controller makes one of the output ends of the dual-axis motor 94 rotate slowly in both directions. At the same time, since the connecting shaft 93 is fixedly connected to the L-shaped translation plate 34, the cylinder 92 and the dual-axis motor 94 will rotate, so that several pre-compression frames 105 and several extension rods 202 rotate slowly in both directions, so as to slightly disturb and re-distribute the unevenly distributed ceramic powder inside.

[0065] After a short period of time, the controller causes the electromagnetic ring 304 to attract several magnet blocks 302, causing the locking rod 301 to disengage from the second locking slot 107. At this time, the second spring 203 resets, making the locking rod 301 correspond to the position of the first locking slot 106. Then, the electromagnetic ring 304 stops attracting several magnet blocks 302, causing the locking rod 301 to engage with the first locking slot 106 again. Subsequently, the controller causes the dual-axis motor 94 to drive several pre-compression frames 105 to descend synchronously again, and to pre-compress and test the ceramic powder after disturbance and homogenization. Afterward, the dual-axis motor 94 drives several pre-compression frames 105 to reset, and the first electric push rod 31 drives the vision sensor 5 to perform a re-inspection operation. When the vision sensor 5 detects that the sedimentation difference of the pre-compressed ceramic powder is qualified and the uniformity meets the standard, the subsequent formal molding operation is performed. When the vision sensor 5 detects that the pre-compressed ceramic powder still has uneven distribution defects, the controller causes the alarm to sound, reminding the user to perform maintenance.

[0066] The above-mentioned pre-compression testing process can automatically identify and correct defects in the uneven distribution of powder, thereby improving the uniformity of the green body density from the root. Compared with the existing technology that relies solely on vibration leveling or manual experience to judge the distribution of powder, it can reduce the risk of green body delamination and cracking, improve the yield of ceramic products, and at the same time, by reducing the number of defective green bodies entering the high-temperature sintering process, it can achieve the energy-saving and environmental protection requirements of ceramic production.
