Abstract
Description
Technical Field
[0001] This invention relates to the field of MCH ceramic base production technology, specifically to pink ceramic bases and an adjustable-size ceramic green body slitting machine for their production. Background Technology
[0002] MCH ceramic substrates are high-strength, high-temperature resistant, thermally shock resistant, and have good insulation and withstand voltage properties. They are widely used in electronic packaging, sensors, aerospace, and other fields. Commonly used MCH ceramic substrates are generally white, but pink ceramic substrates are becoming increasingly popular due to their vibrant color. However, current pink ceramic substrate production suffers from inconsistent color and hue, necessitating the development of specifically designed pink ceramic substrates with stable and uniform color.
[0003] In addition, the production process of MCH ceramic base generally includes multiple steps such as raw material mixing and nano-sand milling, material ball preparation, solvent dispersion, mixed ball milling, degassing, casting, blank cutting and aging. Among them, blank cutting is a key link in the production process, which requires the use of a ceramic blank cutting machine to complete the cutting of ceramic blanks in order to keep the blanks clean and intact.
[0004] Currently, existing ceramic blank slitting machines primarily adjust the blade spacing manually by adjusting the handwheel on the blade holder shaft to align the blades on the shaft with the blade grooves on the blade holder, then lowering and fixing the blade shaft. This method requires gradually adjusting and fixing the position of each blade to ensure the blade spacing meets the slitting requirements. However, this adjustment method suffers from low efficiency and high operational complexity, which increases the limitations of the entire slitting machine. Summary of the Invention
[0005] The purpose of this invention is to provide a pink ceramic base with stable and uniform pink color, and also to provide an adjustable-size ceramic green body slitting machine for producing the aforementioned pink ceramic base, so as to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a pink ceramic base, the preparation process of which includes raw material mixing and nano-sand milling, ball preparation, solvent dispersion, mixed ball milling, degassing, casting, blank cutting, and aging. The alumina powder in the formula accounts for 95wt%~95.9wt% by mass, with a particle size of 1.1μm~3.5μm and a surface area of 5m². 2 / g~15m 2 / g, titanium dioxide content is 0.8wt%~1.5wt%, binder PVB accounts for 5wt%~7wt% of the dry powder in the ingredients, dispersant DBP accounts for 8wt%~11wt% of the dry powder in the ingredients, and plasticizer castor oil accounts for 1.5wt%~3wt% of the dry powder in the ingredients.
[0007] An adjustable-size ceramic green body slitting machine for producing the aforementioned pink ceramic base includes a conveyor, a support frame, hydraulic cylinders, and slitting blades. The support frame is provided on one side of the top of the conveyor, and hydraulic cylinders are symmetrically installed inside the support frame. The slitting blades are provided between the support frame and the conveyor. An adjustment mechanism is provided at one end of the hydraulic cylinder inside the support frame. The adjustment mechanism includes a mounting plate, an electric push rod, an adjustment plate, an adjustment groove, and a limiting post. The mounting plate is located at one end of the hydraulic cylinder. The adjustment plate is movably connected between the mounting plate and the cutting blade. An electric push rod connected to the adjustment plate is installed at the bottom end of the mounting plate. An adjustment groove is provided inside the adjustment plate.
[0008] Preferably, the top end of the slitting blade is provided with a limiting post that penetrates the adjustment groove, and the slitting blade and the adjustment plate form a sliding structure through the adjustment groove and the limiting post, wherein the limiting post is configured as a "T" shaped structure.
[0009] Preferably, the bottom end of the mounting plate is symmetrically provided with support grooves, and the top end of the adjustment plate is symmetrically provided with support plates. The adjustment plate and the mounting plate form a sliding structure through the support plates and support grooves. Both the support plates and support grooves are set as "T" shaped structures.
[0010] Preferably, the top end of the slitting blade is symmetrically provided with a support block, and the bottom end of the mounting plate is symmetrically provided with a support rod. The slitting blade and the mounting plate form a sliding structure through the support rod and the support block. The support rod is set as a "U" shaped structure.
[0011] Preferably, an anti-tipping mechanism is provided on the inner side of the support frame. The anti-tipping mechanism consists of a linkage rope, a flip plate, an anti-tipping plate, a support shaft, and a torsion spring. The flip plate is rotatably connected to both sides inside the support frame through the support shaft.
[0012] Preferably, a torsion spring sleeved on the outside of the support shaft is connected between the flip plate and the support frame, an anti-tipping plate is provided at one end of the flip plate, and a linkage rope passing through the support frame is connected between the flip plate and the mounting plate.
[0013] Preferably, an adjustment mechanism is provided on the inner side of the flip plate and the anti-tipping plate, the adjustment mechanism consisting of a threaded hole, a screw and a handle.
[0014] Preferably, the flip plate has a threaded hole inside, and a screw that is rotatably connected to the anti-tipping plate via a bearing is threaded inside the threaded hole. A handle is connected to the end of the screw away from the anti-tipping plate.
[0015] Preferably, the flip plate has symmetrically provided limit holes inside, and one end of the anti-tipping plate is symmetrically provided with a limit rod that passes through the limit hole. The anti-tipping plate and the flip plate form a sliding structure through the limit hole and the limit rod.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By adjusting the alumina mass ratio, particle size, surface area, titanium dioxide content, and the amounts of binder, dispersant, and plasticizer in the formula, a stable, safe, and uniform pink ceramic base can be produced. 2. Existing ceramic slab slitting machines suffer from low efficiency and high operational complexity in adjusting the blade spacing, which limits the overall slitting machine. This invention addresses this by incorporating an adjustment mechanism. Since the adjustment plate and mounting plate are slidably connected via a support plate and support groove, the adjustment plate moves horizontally back and forth during the operation and extension of the electric push rod. The blades are slidably connected to the adjustment plate via limiting posts and adjustment grooves, and simultaneously to the mounting plate via support rods and support blocks. Furthermore, the different inclination angles of the multiple adjustment grooves facilitate rapid adjustment of the blade spacing. This adjustment method improves efficiency, simplifies operation, and reduces the limitations of ceramic slab slitting machines.
[0017] 3. Existing ceramic blank slitting machines are prone to tipping over during the slitting or separation process using slitting blades, which can easily result in defective products. This invention addresses this issue by incorporating an anti-tipping mechanism. Since the tilting plate is rotatably connected to the support frame via a support shaft and simultaneously linked to the mounting plate via a linkage rope, the tilting plate deflects around the support shaft as the mounting plate moves downwards, causing the anti-tipping plate to contact the ceramic blank. This anti-tipping plate effectively limits the movement of the ceramic blank, preventing it from tipping over and ensuring product quality while preventing defective products.
[0018] 4. This invention features an adjustment mechanism. Since the screw is threadedly connected to the flipping plate through a threaded hole and rotatably connected to the anti-tipping plate through a bearing, the anti-tipping plate can be moved by rotating the handle and the screw, thereby adjusting the distance between the anti-tipping plate and the flipping plate. This allows the anti-tipping plate to be used for anti-tipping operations of ceramic blanks of various sizes, improving its adaptability. Attached Figure Description

Detailed Implementation
[0021] 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. Example
[0022] This invention provides a pink ceramic substrate, the preparation process of which includes raw material mixing and nano-sand milling, pellet preparation, solvent dispersion, mixed ball milling, degassing, casting, blank cutting, and aging. The alumina powder in the formula accounts for 95wt%~95.9wt% by mass, with a particle size of 1.1μm~3.5μm and a surface area of 5m². 2 / g~15m 2 / g, titanium dioxide content is 0.8wt%~1.5wt%, binder PVB accounts for 5wt%~7wt% of the dry powder in the ingredients, dispersant DBP accounts for 8wt%~11wt% of the dry powder in the ingredients, and plasticizer castor oil accounts for 1.5wt%~3wt% of the dry powder in the ingredients. Example
[0023] Please see Figures 1-3 and Figure 6The present invention provides a technical solution: a ceramic blank slitting machine that can quickly adjust the thickness of the slitting, including a conveyor 1, a support frame 2, a hydraulic cylinder 3 and a slitting blade 4. The support frame 2 is provided on one side of the top of the conveyor 1, and the hydraulic cylinder 3 is symmetrically installed inside the support frame 2. The slitting blade 4 is provided between the support frame 2 and the conveyor 1. The conveyor 1 is prior art, so it will not be described in detail here. See Figures 1-3 and Figure 6 It can be seen that after the ceramic blank is placed on the conveyor 1, the ceramic blank can be conveyed by the conveyor 1. When it is conveyed to the bottom of the slitting blade 4, it stops. At this time, the hydraulic cylinder 3 controls the slitting blade 4 to move down and perform slitting operation on the ceramic blank. After the slitting is completed, the hydraulic cylinder 3 controls the slitting blade 4 to move up. At this time, the conveyor 1 continues to convey the ceramic blank to be slitted and the slitted ceramic blank.
[0024] See Figure 2 , Figure 4 and Figure 5 It is known that the flip plate 602 has symmetrically provided limiting holes 12 inside, and the anti-tipping plate 603 has symmetrically provided limiting rods 13 that pass through the limiting holes 12 at one end. The anti-tipping plate 603 and the flip plate 602 form a sliding structure through the limiting holes 12 and the limiting rods 13, which can play a supporting and guiding role for the anti-tipping plate 603, so as to prevent the anti-tipping plate 603 from rotating with the screw 702.
[0025] See Figures 2-4 and Figure 6 It is known that an adjustment mechanism 5 is provided at one end of the hydraulic cylinder 3 inside the support frame 2. The adjustment mechanism 5 includes a mounting plate 501, an electric push rod 502, an adjustment plate 503, an adjustment groove 504, and a limiting post 505. The mounting plate 501 is located at one end of the hydraulic cylinder 3. The adjustment plate 503 is movably connected between the mounting plate 501 and the cutting blade 4. The bottom end of the mounting plate 501 is equipped with an electric push rod 502 connected to the adjustment plate 503. The adjustment groove 504 is provided inside the adjustment plate 503. The top end of the cutting blade 4 is provided with a limiting post 505 that penetrates the adjustment groove 504. The cutting blade 4 and the adjustment plate 503 form a sliding structure through the adjustment groove 504 and the limiting post 505. The limiting post 505 is set as a "T" shaped structure. See Figures 2-4 and Figure 6As can be seen, since the adjusting plate 503 and the mounting plate 501 are slidably connected through the support plate 8 and the support groove 9, the adjusting plate 503 moves back and forth in the horizontal direction during the operation and extension of the electric push rod 502. Since the slitting blade 4 is slidably connected to the adjusting plate 503 through the limiting post 505 and the adjusting groove 504, and is slidably connected to the mounting plate 501 through the support rod 10 and the support block 11, and the inclination angles of the multiple sets of adjusting grooves 504 are different, it is easy to quickly adjust the spacing of the slitting blade 4. By adopting this adjustment method, the adjustment efficiency is improved and the operation is simple, reducing the limitations of the ceramic blank slitting machine.
[0026] See Figure 2 , Figure 4 and Figure 6 It can be seen that the bottom end of the mounting plate 501 is symmetrically provided with support grooves 9, and the top end of the adjustment plate 503 is symmetrically provided with support plates 8. The adjustment plate 503 and the mounting plate 501 form a sliding structure through the support plates 8 and the support grooves 9. The support plates 8 and the support grooves 9 are both set as "T" shaped structures, which can play a role in supporting and limiting the adjustment plate 503, so that the adjustment plate 503 can only move back and forth in the horizontal direction.
[0027] See Figure 1 , Figure 2 and Figures 4-6 It is known that an anti-tipping mechanism 6 is provided on the inner side of the support frame 2. The anti-tipping mechanism 6 is composed of a linkage rope 601, a flipping plate 602, an anti-tipping plate 603, a support shaft 604, and a torsion spring 605. The flipping plate 602 is rotatably connected to both sides inside the support frame 2 through the support shaft 604. A torsion spring 605 sleeved on the outside of the support shaft 604 is connected between the flipping plate 602 and the support frame 2. An anti-tipping plate 603 is provided at one end of the flipping plate 602. A linkage rope 601 that penetrates the support frame 2 is connected between the flipping plate 602 and the mounting plate 501. See Figure 1 , Figure 2 and Figures 4-6 As can be seen, since the tilting plate 602 is rotatably connected to the support frame 2 through the support shaft 604, and is also linked to the mounting plate 501 through the linkage rope 601, the tilting plate 602 deflects around the support shaft 604 as the axis during the downward movement of the mounting plate 501, and the anti-tipping plate 603 contacts the ceramic blank. Thus, the anti-tipping plate 603 can limit the ceramic blank to prevent it from tipping over, which makes it easier to ensure product quality and prevent defective products. During the upward movement of the slitting blade 4 controlled by the hydraulic cylinder 3, the tilting plate 602 rotates and resets under the action of the torsion spring 605, which can prevent obstruction of the conveying of the ceramic blank.
[0028] See Figure 1 , Figure 2 and Figures 4-6 It is known that an adjustment mechanism 7 is provided on the inner side of the flip plate 602 and the anti-tipping plate 603. The adjustment mechanism 7 consists of a threaded hole 701, a screw 702 and a handle 703. The flip plate 602 has a threaded hole 701 inside. The screw 702, which is rotatably connected to the anti-tipping plate 603 through a bearing, is threaded inside the threaded hole 701. The end of the screw 702 away from the anti-tipping plate 603 is connected to the handle 703. See Figure 2 , Figure 4 and Figure 5 As can be seen, since the screw 702 is threadedly connected to the flip plate 602 through the threaded hole 701, and is rotatably connected to the anti-tipping plate 603 through the bearing, the anti-tipping plate 603 can be moved by rotating the handle 703 and the screw 702, thereby adjusting the distance between the anti-tipping plate 603 and the flip plate 602. This allows the anti-tipping plate 603 to be applicable to anti-tipping operations of ceramic blanks of various sizes, improving its adaptability.
[0029] See Figure 2 , Figure 3 and Figure 6 It can be seen that the top end of the slitting blade 4 is symmetrically provided with a support block 11, and the bottom end of the mounting plate 501 is symmetrically provided with a support rod 10. The slitting blade 4 and the mounting plate 501 form a sliding structure through the support rod 10 and the support block 11. The support rod 10 is set as a "U" shaped structure, which can play a role in supporting and guiding the slitting blade 4, so as to prevent the slitting blade 4 from deviating during the sliding process, thereby making the sliding process of the slitting blade 4 more stable.
[0030] Working principle: When using this ceramic blank slitting machine with quickly adjustable slicing thickness, the electric push rod 502 is activated, causing the adjusting plate 503 to move horizontally. Simultaneously, the slitting blades 4 move horizontally in conjunction with the adjusting groove 504 and the limiting post 505, thus facilitating rapid adjustment of the spacing between the slitting blades 4. The ceramic blanks are then conveyed via the conveyor 1, stopping when they reach below the slitting blades 4. At this point, the hydraulic cylinder 3 controls the slitting blades 4 to move downwards and perform the slitting operation on the ceramic blanks. During this process... The tilting plate 602 deflects around the support shaft 604 under the action of the linkage rope 601, and the anti-tipping plate 603 contacts the ceramic blank, so that the ceramic blank can be limited and prevented from tipping over by the anti-tipping plate 603. After the slitting is completed, the hydraulic cylinder 3 controls the slitting blade 4 to move upward, and at the same time the tilting plate 602 rotates and resets under the action of the torsion spring 605. At this time, the conveyor 1 continues to transport the ceramic blank to be slitted and the slitted ceramic blank. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
