[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0034] Please refer to Figures 1 to 7 , the present invention provides a manufacturing system for a multi-layer ceramic substrate, including a stirring tank 1, a pump body 2 and a manufacturing component. The manufacturing component includes a molding plate 3, a plurality of lifting seats 4, a plurality of adjusting plates 5 and a scraper 6. The molding plate 3 has a plurality of molding grooves 7. The manufacturing component further includes a plurality of magnets 8 and a scraping adjustment unit. The scraping adjustment unit includes a scraping and traversing component 9 and a scraping and lifting component 10. The manufacturing component further includes a lifting plate 11, a plurality of lifting components 12, two limiting plates 13, a plurality of first electric heating wires 14, a plurality of second electric heating wires 15, a lifting base 16, a recovery chute 17, two inclined plates 18 and a recovery box 19. The manufacturing component further includes a clamping unit, a screen printing machine 20 and a partition sintering unit. The clamping unit includes a clamping and moving component 21 and a robot arm 22. The partition sintering unit includes a partition base 23, a plurality of sintering mechanisms, a support plate 24, a green sheet moving component 25, a plurality of green sheet lifting components 26, a green sheet telescopic component 27, a U-shaped seat 28 and a plurality of green sheet support columns 29. The sintering mechanism includes a sintering box 38, a plurality of heaters 31, two supporting components 32, two supporting plates 33, a plurality of supporting columns 34, a plurality of bottom supporting cones 35, a sealing component 36 and a sealing plate 37.

[0035] Among them, the pump body 2 is arranged on one side of the stirring tank 1. The forming plate 3 has a plurality of forming grooves 7. The forming plate 3 is arranged below the pump body 2. A plurality of lifting seats 4 are respectively slidably connected to the corresponding forming grooves 7. A plurality of adjusting plates 5 are respectively adapted to the corresponding lifting seats 4 and are arranged above the corresponding lifting seats 4. The scraping plate 6 is located above the forming plate 3. A variety of raw materials of the ceramic substrate are put into the stirring tank 1 for stirring and mixing to obtain ceramic slurry; the pump body 2 pumps the ceramic slurry onto the forming plate 3; the lifting seat 4 drives the adjusting plate 5 to move up and down, thereby adjusting the depth of the forming groove 7 and controlling the thickness of the subsequent green sheet 30; the ceramic slurry naturally flows into the plurality of forming grooves 7; the scraping plate 6 abuts against the forming plate 3 and continuously scrapes, so that each forming groove 7 is filled with ceramic slurry; start to cure the ceramic slurry in the forming groove 7; after curing is completed, the lifting seat 4 and the adjusting plate 5 move up to push the green sheet 30 out of the forming groove 7 for subsequent sintering;

[0036] The adjusting plate 5 is made of alumina and coated with a boron nitride coating on the surface to avoid adhesion between the green sheet 30 and the adjusting plate 5 after curing; in addition, both the adjusting plate 5 and the lifting seat 4 can slide in the forming groove 7 to adjust the forming thickness of the green sheet 30. Among them, the clearance between the adjusting plate 5 and the lifting seat 4 and the forming groove 7 is 0.015 mm, the surface roughness is Ra = 0.1 μm, and the ejection pressure is 8 MPA, so as to avoid leakage of the ceramic slurry before curing and forming.

[0037] Secondly, one ends of a plurality of magnets 8 are respectively arranged below the corresponding adjusting plates 5, and the other ends of the plurality of magnets 8 are respectively inserted into the interiors of the corresponding lifting seats 4. The scraping and adjusting unit is arranged on one side of the stirring tank 1; the scraping and transverse moving member 9 is arranged on one side of the stirring tank 1, and the scraping and lifting member 10 is arranged at the output end of the scraping and transverse moving member 9. The output end of the scraping and lifting member 10 is fixedly connected to the scraping plate 6. When the adjusting plate 5 is installed, it is directly placed into the forming groove 7 and adsorbed to the lifting seat 4 made of metal material through the magnet 8, thereby completing the installation of the adjusting plate 5. When disassembly is required, the lifting seat 4 moves up to completely move the adjusting plate 5 out of the forming groove 7. At this time, the adjusting plate 5 can be taken away by clamping it for replacement and maintenance to avoid adhesion to the green sheet 30 after the coating is lost after long-term use; when the scraping plate 6 needs to be adjusted, the scraping and transverse moving member 9 and the scraping and lifting member 10 are started to drive the scraping plate 6 to abut against the upper part of the forming plate 3 and continuously scrape, so as to scrape away the excess slurry; the scraping and transverse moving member 9 is an electric slide rail, and the scraping and lifting member 10 is a self-locking cylinder.

[0038] Meanwhile, the lifting plate 11 is fixedly connected to the lower parts of the plurality of lifting seats 4. Two limiting plates 13 are arranged on both sides of the forming plate 3. A plurality of first electric heating wires 14 are respectively arranged inside the corresponding lifting seats 4. A plurality of second electric heating wires 15 are all arranged inside the forming plate 3 and are respectively sleeved outside the corresponding forming grooves 7. The lifting base 16 is placed on one side of the mixing tank 1. A plurality of lifting components 12 and the forming plate 3 are all arranged above the lifting base 16. A plurality of lifting components 12 are located between the forming plate 3 and the lifting base 16. The output end of the lifting component 12 is fixedly connected to the lifting plate 11. The recovery chute 17 is placed below the lifting base 16. Two inclined plates 18 are symmetrically arranged at both ends of the forming plate 3. The recovery box 19 is placed at one end of the recovery chute 17. The lifting base 16 supports the lifting components 12. The lifting components 12 are self-locking cylinders. When the lifting components 12 are activated, they drive the lifting plate 11 to move up and down, and then drive the plurality of lifting seats 4 and the adjusting plate 5 to move up and down to adjust the forming thickness of the green sheet 30. At the same time, the limiting plates 13 on both sides prevent the ceramic slurry from flowing to both sides. Relying on the action of the inclined plates 18, the ceramic slurry flows to both ends of the forming plate 3 and then falls on the recovery chute 17 and uniformly flows into the recovery box 19 for collection and storage for reuse. In addition, after the ceramic slurry is filled inside the forming groove 7, the first electric heating wires 14 are activated to heat the lifting seats 4. At the same time, the adjusting plate 5 generates heat to heat and cure the ceramic slurry from below the forming part. The second electric heating wires 15 are activated to heat and cure the ceramic slurry from outside the forming groove 7, thereby ensuring the uniformity of heating and curing of the ceramic slurry.

[0039] In addition, the clamping unit is arranged at one end of the lifting base 16. The screen printing machine 20 is arranged on the side of the lifting base 16 away from the mixing tank 1. The zoning sintering unit is arranged on the side of the screen printing machine 20 away from the lifting base 16. The clamping and moving component 21 is arranged at one end of the lifting base 16. The robotic arm 22 is arranged at the output end of the clamping and moving component 21. The clamping and moving component 21 is an electric slide rail. When the clamping and moving component 21 is activated, it drives the robotic arm 22 to move between the forming plate 3, the screen printing machine 20 and the zoning sintering unit, and then moves the cured green sheet 30 into the screen printing machine 20 for circuit printing. After the circuit printing is completed, it is moved to the zoning sintering unit for sintering and forming.

[0040] Then, the partition base 23 is placed on the side of the screen printing machine 20 away from the lifting base 16. The support plate 24 is disposed between the screen printing machine 20 and the partition base 23. A plurality of the sintering mechanisms are sequentially arranged above the partition base 23. The green sheet moving member 25 is arranged above the support plate 24. A plurality of the green sheet lifting members 26 are sequentially arranged at the output end of the green sheet moving member 25. The output ends of the plurality of the green sheet lifting members 26 are fixedly connected to the green sheet telescopic member 27. The output end of the green sheet telescopic member 27 is fixedly connected to the U-shaped seat 28. A plurality of the green sheet support columns 29 are sequentially arranged inside the U-shaped seat 28. A plurality of green sheets are placed on the plurality of the green sheet support columns 29. The partition base 23 supports the sintering mechanism. The support plate 24 supports the green sheet moving member 25. The green sheet moving member 25 is an electric slide rail. The green sheet lifting member 26 and the green sheet telescopic member 27 are both self-locking cylinders. After the mechanical arm 22 moves the green sheet after circuit printing above the U-shaped seat 28, it is supported by the plurality of the green sheet support columns 29. At this time, a plurality of the green sheets 30 are repeatedly placed to form multiple layers of the green sheets 30. Then the green sheet moving member 25 is started to adjust the U-shaped seat 28 to align with the corresponding sintering box 38. The green sheet telescopic member 27 is started to move the green sheet 30 into the sintering box 38, and then sintering can be carried out. Among them, relying on the plurality of the sintering mechanisms, the multiple layers of the green sheets 30 with different specifications can be sintered separately to improve the sintering quality.

[0041] Again, the sintering box 38 is disposed above the partition base 23, a plurality of the heaters 31 are sequentially disposed inside the sintering box 38, two of the abutting members 32 are symmetrically disposed on both sides of the sintering box 38, output ends of the two abutting members 32 penetrate through the sintering box 38 and are respectively fixedly connected to the corresponding abutting plates 33, a plurality of the abutting columns 34 are respectively disposed on the corresponding abutting plates 33, a plurality of the bottom support cones 35 are all disposed on the inner bottom wall of the sintering box 38, the closing member 36 is disposed above the sintering box 38, and an output end of the closing member 36 is fixedly connected to the closing plate 37. After multiple layers of the green sheets move above the bottom support cones 35, the U-shaped seat 28 moves downward, so that the bottom support cones 35 contact the lower sides of the green sheets, and at the same time the green sheet support columns 29 no longer play a supporting role. At this time, the U-shaped seat 28 moves out of the sintering box 38, and then the abutting members 32 are activated to drive the abutting plates 33 to move, so that the plurality of abutting columns 34 contact the two sides of the green sheets. Finally, the closing member 36 is activated to drive the closing plate 37 to move downward to close the sintering box 38. At this time, the heaters 31 can be started to start sintering; thus, relying on the bottom support cones 35 and the abutting columns 34 to contact and abut against the green sheets, a fixing effect is achieved, and the contact area with the green sheets can also be reduced, thereby increasing the heating area and improving the sintering quality and stability; both the abutting members 32 and the closing member 36 are self-locking cylinders.

[0042] When using the manufacturing system of a multi-layer ceramic substrate according to this embodiment, a variety of raw materials of the ceramic substrate are put into the stirring box 1 for stirring and mixing to obtain ceramic slurry; the pump body 2 pumps the ceramic slurry onto the forming plate 3; the lifting seat 4 drives the adjusting plate 5 to move up and down, thereby adjusting the depth of the forming groove 7 and controlling the thickness of the subsequent green sheets; the ceramic slurry naturally flows into the plurality of forming grooves 7; the scraper 6 abuts against the forming plate 3 and continuously scrapes, so that each forming groove 7 is filled with ceramic slurry; the ceramic slurry in the forming groove 7 starts to be cured; after the curing is completed, the lifting seat 4 and the adjusting plate 5 move upward to eject the green sheet 30 out of the forming groove 7 for subsequent sintering;

[0043] Through the above structural arrangement, on the basis of optimizing the traditional casting method, there is no need for a doctor blade to control the gap, nor is it necessary to continuously run a baseband to form the green sheet 30. Relying on the pre-adjusted forming groove 7 to provide space for the formation of the green sheet 30, the doctor blade only needs to scrape off the excess slurry above the forming plate 3, and thus there is no need to rely on the speed of the baseband and the pressure control of the doctor blade, greatly reducing the operating cost and control difficulty, and thus it is easier to produce high-precision and high-quality ceramic substrates.

[0044] Please refer toFigure 8 , the present invention also provides a method for manufacturing a multi-layer ceramic substrate, comprising the following steps:

[0045] S1: Put various raw materials of the ceramic substrate into the stirring tank 1 for stirring and mixing to obtain ceramic slurry;

[0046] S2: The pump body 2 pumps the ceramic slurry onto the forming plate 3;

[0047] S3: The lifting seat 4 drives the adjusting plate 5 to move up and down, thereby adjusting the depth of the forming groove 7 and controlling the thickness of the subsequent green sheet;

[0048] S4: The ceramic slurry naturally flows into multiple forming grooves 7;

[0051] S7: After curing is completed, the lifting seat 4 and the adjusting plate 5 move up to eject the green sheet out of the forming groove 7 for subsequent sintering.

[0052] Wherein, put various raw materials of the ceramic substrate into the stirring tank 1 for stirring and mixing to obtain ceramic slurry; the pump body 2 pumps the ceramic slurry onto the forming plate 3; the lifting seat 4 drives the adjusting plate 5 to move up and down, thereby adjusting the depth of the forming groove 7 and controlling the thickness of the subsequent green sheet 30; the ceramic slurry naturally flows into multiple forming grooves 7; the scraper 6 abuts against the forming plate 3 and continuously scrapes, so that each forming groove 7 is filled with ceramic slurry; start curing the ceramic slurry in the forming groove 7; after curing is completed, the lifting seat 4 and the adjusting plate 5 move up to eject the green sheet 30 out of the forming groove 7 for subsequent sintering.
