Abstract
Description
Technical Field
[0001] This invention relates to the field of cutting technology, specifically a cutting device for ceramic green bodies. Background Technology
[0002] Silicon nitride, a compound composed of silicon and nitrogen, is an important engineering ceramic material with excellent thermal stability, mechanical properties, and chemical stability. Its crystal structure is similar to that of quartz, but silicon nitride has higher hardness, a higher melting point, and lower thermal conductivity. These properties make silicon nitride a promising material for many demanding applications, such as high-temperature engine components, cutting tools, high-temperature furnace tubes, and integrated circuit substrates. The silicon nitride preparation process requires cutting the cast green billet. Currently, the cutting equipment on the market has two major problems: first, the cutting method uses a roller cutter, which generates a lot of debris during the cutting of the green billet, contaminating the surface of the green billet; second, the conveying method is basically a clamping method for conveying the green billet, which makes the surface of the green billet very easy to produce indentations.
[0003] After forming, ceramic green bodies usually need to be cut to meet the size and shape requirements of different products. Traditional cutting methods mostly use mechanical cutting or manual cutting, which have the following problems: low cutting accuracy, easy to produce burrs or cracks at the cut, low cutting efficiency, difficulty in meeting the needs of mass production, easy to cause deformation or damage to the green body during the cutting process, and low yield. Therefore, there is an urgent need for a high-precision, high-quality ceramic green body cutting method that is suitable for automated production. Patent CN219599895U8 mentions a slitting device for a casting machine. The slitting blade used in this patent is a metal circular blade, which cuts the green body by shearing. However, the metal circular blade will produce a lot of serrations when cutting thick film green bodies, which will lead to a lot of debris. Therefore, it cannot be used well on high thermal conductivity silicon nitride or aluminum nitride green bodies.
[0004] Conventional dust-adhesive rollers require manual replacement and cleaning after adsorbing excessive impurities, which is labor-intensive and affects work efficiency. Therefore, a dust-adhesive roller system that can automatically clean without stopping the machine is needed. Patent CN221602618U mentions an online dust-adhesive roller cleaning system. This patent uses a four-roller coaxial rotation switching method to replace the dust-adhesive rollers. However, the billet cannot be cleaned when replacing the dust-adhesive rollers, and some impurities will be missed and cannot be removed. Currently, most negative pressure suction cups only have adsorption functions and do not have safety devices. This cannot guarantee the safety of the adsorbed material when the negative pressure suction cup malfunctions. Therefore, a locking device that can protect the billet safety when the negative pressure suction cup malfunctions is needed. Summary of the Invention
[0005] The purpose of this invention is to provide a cutting device for ceramic green bodies to solve the problems mentioned in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: the cutting device includes a feeding mechanism, a cutting mechanism, a blanking mechanism, and a feeding mechanism. The blanking mechanism is located to the side of the feeding mechanism. The feeding mechanism includes a negative pressure platform. A large support is provided below the negative pressure platform. A purification mechanism is provided to the side of the negative pressure platform. During operation, the negative pressure platform adsorbs the ceramic blank, so that the blank is fixed on the negative pressure platform and does not easily move unnecessarily. The purification mechanism simultaneously removes impurities from the ceramic blank.
[0007] Furthermore, the unloading section includes a negative pressure suction cup, a unloading basket, and a transmission mechanism. The negative pressure suction cup is connected to the transmission mechanism, a negative pressure suction cup electronic control system is provided on the side of the transmission mechanism, and a support is provided below the transmission mechanism.
[0008] Furthermore, the negative pressure suction cup includes a suction cup surface, and a negative pressure control element is disposed above the suction cup surface. The negative pressure control element is connected to the suction cup surface via an air supply pipe. A first cylinder is located on each side of the air supply pipe, and a squeezing plate is disposed at the end of each first cylinder near the air supply pipe. A limiting slider is disposed on each side of each squeezing plate. A pressure alarm element is disposed to the side of the negative pressure control element. In this invention, when the negative pressure suction cup adsorbs the blank, the suction cup surface first contacts the blank, the negative pressure control element sucks away the air from the suction cup surface, and the pressure alarm element detects whether the pressure between the suction cup surface and the blank is appropriate. When the pressure between the suction cup surface and the billet is unqualified, the pressure alarm element sends a stop signal to the negative pressure control element and notifies the staff to check, so as to avoid the billet falling and being damaged when the negative pressure suction cup moves. When the pressure between the suction cup surface and the billet is qualified, the two first cylinders drive the two extrusion plates to move closer to each other, and the two extrusion plates clamp the air supply pipe to close the air supply pipe and stop the air supply. The two extrusion plates lock the pressure between the suction cup surface and the billet to prevent the billet from falling due to the failure of the negative pressure control element when the negative pressure suction cup moves.
[0009] Furthermore, the impurity removal mechanism includes a housing, an anhydrous ethanol tank, an electrical control box, a slide rail, a spraying element, a water trough, a second set of sticky rollers, a vision detection element, and a first set of sticky rollers. The anhydrous ethanol tank and the electrical control box are both located on the outside of the housing, while the slide rail is located on the inside of the housing. The second and first sets of sticky rollers are connected to the slide rail. The vision detection element is located on the side of the second set of sticky rollers. The spraying element is located above the slide rail on the side closest to the first set of sticky rollers. The water trough is located below the spraying element. In this invention, a motor drive device (not shown in the figure) is provided on the side of the slide rail closest to the electrical control box. The two dust-adhesive roller groups are driven by a motor drive to move on the slide rail. During the billet transfer, the two dust-adhesive roller groups adsorb impurities on the billet surface. At the same time, the vision detection element detects the two dust-adhesive roller groups. If the two dust-adhesive roller groups have a lot of impurities, it means that the one dust-adhesive roller group is no longer suitable for work. At this time, the two dust-adhesive roller groups are driven by a motor drive to move along the slide rail into the cleaning area (the cleaning area is below the spray element) for cleaning. The two dust-adhesive roller groups are driven by a motor drive to move to the initial position of the one dust-adhesive roller group to adsorb impurities on the billet surface.
[0010] Furthermore, the second sticky roller assembly includes a sticky roller, a connecting rod, a second cylinder, a limiting track, and a limiting block. The sticky roller is connected to the limiting block, and the limiting block and the second cylinder are connected via the connecting rod. The limiting block is located inside the limiting track. The structure and internal configuration of the first sticky roller assembly are the same as those of the second sticky roller assembly. When the first sticky roller assembly enters the cleaning area, the second cylinder inside the first sticky roller assembly drives the sticky roller inside the first sticky roller assembly to move towards the slide rail. At this time, anhydrous ethanol from the anhydrous ethanol tank is sprayed onto the first sticky roller assembly through the spraying element, thereby cleaning the first sticky roller assembly. The anhydrous ethanol flows out through the water tank. After the first set of sticky rollers is cleaned, the second cylinder inside the first set of sticky rollers drives the sticky rollers in the first set to move away from the slide rail. Then, the motor drive device controls the first set of sticky rollers to move to the initial position of the second set of sticky rollers. The first set of sticky rollers is inspected by a vision detection element. When impurities are found on the first set of sticky rollers, it means that the second set of sticky rollers is no longer suitable for work. At this time, the above steps are repeated. The motor drive device drives the second set of sticky rollers to move along the slide rail into the cleaning area for cleaning, while the first set of sticky rollers is driven to move to the initial position.
[0011] Furthermore, the mechanical gripper includes a table frame, a moving device, a motor, and a gripper head. The moving device is located above the table frame, and the motor is located above the moving device. The motor and the gripper head are connected. When feeding begins, the motor drives the moving device to move the mechanical gripper to the working position.
[0012] Furthermore, the cutting mechanism includes a base, a second fixed plate, a slider, a cutter, a porous ceramic plate, and a negative pressure adsorption device. The second fixed plate is connected to the base, the slider is connected to the second fixed plate, and the slider is connected to the cutter. The porous ceramic plate is positioned below the cutter and on a negative pressure platform. A negative pressure adsorption device is located below the porous ceramic plate. During operation, the cutter uses one of a roller cutter, a hot-pressing cutter, or an energy cutter for cutting. By adjusting the appropriate amplitude and frequency, problems such as debris can be effectively avoided. At the same time, the porous ceramic plate is used to adsorb and fix the green blank during cutting, and the debris generated during cutting is collected by the negative pressure adsorption device below.
[0013] Furthermore, the feeding mechanism includes a first fixed plate, a feeding shaft is provided on one side of the first fixed plate, a control box is provided on the other side of the first fixed plate, a guide roller is provided on the side of the feeding shaft, and a height detection element is provided on the upper side of the first fixed plate. When feeding begins, the control box drives the feeding shaft to rotate and feed the billet out. The billet moves along the guide roller towards the negative pressure table. At the same time, the height detection element starts to measure the height of the billet and controls the unwinding speed to prevent the problem of mismatch between feeding and transmission speed.
[0014] Furthermore, the feeding basket includes a fence and a guide block. The fence is located below the guide block. When the blank is cut and needs to be placed into the feeding basket, the guide block limits the direction and angle of the blank entering the basket, so that all blanks are neatly placed into the feeding basket. The fence fixes the guide block and, together with the guide block, limits and protects the blanks already placed in the feeding basket.
[0015] Furthermore, a support net is provided above the negative pressure platform, and a buffer net is provided above the support net. The support net is made of Teflon mesh, polyester mesh, or metal mesh, etc., and the buffer net is made of polyester mesh, nylon mesh, or metal fine mesh, etc. During the transfer of the billet, the negative pressure platform provides a stable negative pressure so that the billet is adsorbed and fixed on the buffer net, effectively reducing problems such as indentation.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The adsorption and transmission mechanism consists of a support net and a buffer net. The support net is made of Teflon mesh, polyester mesh, or metal mesh, while the buffer net is made of polyester mesh, nylon mesh, or fine metal mesh. It adopts a negative pressure transmission method, which can effectively reduce problems such as indentation. It uses a roller cutter, hot-pressing punch cutter, or energy knife for cutting. Adjusting the appropriate amplitude and frequency can effectively avoid problems such as debris. When the green body is transported, negative pressure transmission is used, and the claw head holds the conveyor net for transmission. This ensures high precision in cutting the green body angle dimensions. The material feeding multi-hole negative pressure suction cup is equipped with a sponge, PU foam, or EVA foam buffer layer to protect the surface of the green ceramic and prevent adsorption marks from being generated during transfer.
[0018] 2. The negative pressure suction cup of this invention has an automatic locking function. That is, a first cylinder and a squeezing plate are set on each side of the air supply pipe. Through the cooperation of the two first cylinders and the two squeezing plates, the negative pressure suction cup can be in a vacuum-locked state after adsorbing the blank. When a fault occurs in a certain part of the negative pressure suction cup, the vacuum state of the negative pressure suction cup will not be broken, thereby avoiding damage to the blank due to falling off. At the same time, a pressure alarm element is set after the negative pressure suction cup. When the negative pressure suction cup is detected to have no suction, the alarm is triggered to avoid further losses and notify the staff to carry out maintenance.
[0019] 3. The impurity removal mechanism of this invention has an automatic cleaning function. It includes a first group of sticky rollers and a second group of sticky rollers, with the second group of sticky rollers located after the first group of sticky rollers. Under normal conditions, the sticky rollers in both groups work simultaneously to remove impurities from the blank in two stages. A visual detection element is set at the second group of sticky rollers. When impurities are detected on the surface of the second group of sticky rollers, it indicates that the first group of sticky rollers is not suitable for operation. The first group of sticky rollers is then moved into the cleaning device for cleaning. After the first group of sticky rollers is cleaned, it moves to the original position of the second group of sticky rollers, and the second group of sticky rollers moves to the original position of the first group of sticky rollers. This ensures that at least one sticky roller is in operation while removing impurities without stopping the machine. Attached Figure Description

[0032] 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.
[0033] Example: Figure 1 , Figure 3 As shown, the present invention provides a technical solution, a cutting device, which includes a feeding mechanism 1, a cutting mechanism 2, a blanking mechanism 3, and a feeding mechanism 4. The blanking mechanism 3 is disposed on the side of the feeding mechanism 4. The feeding mechanism 4 includes a negative pressure table 41, a large support 43 is disposed below the negative pressure table 41, a cleaning mechanism 42 is disposed on the side of the negative pressure table 41, and a mechanical gripper 44 is disposed on the other side of the cleaning mechanism 42. During operation, the negative pressure table 41 adsorbs the ceramic blank, so that the blank is fixed on the negative pressure table 41 and does not move unnecessarily. The cleaning mechanism 42 cleans the ceramic blank at the same time.
[0034] like Figure 2As shown, the unloading part 3 includes a negative pressure suction cup 31, a unloading basket 32, and a transmission mechanism 33. The negative pressure suction cup 31 is connected to the transmission mechanism 33. A negative pressure suction cup electrical control system 34 is provided on the side of the transmission mechanism 33, and a bracket 35 is provided below the transmission mechanism 33.
[0035] like Figure 4 As shown, the negative pressure suction cup 31 includes a suction cup surface 317. A negative pressure control element 311 is disposed above the suction cup surface 317. The negative pressure control element 311 is connected to the suction cup surface 317 via an air supply pipe 314. There is a first cylinder 313 on both sides of the air supply pipe 314. Each first cylinder 313 has a squeezing plate 315 disposed at one end near the air supply pipe 314. A limit slider 312 is disposed on both sides of each squeezing plate 315. A pressure alarm element 316 is disposed on the side of the negative pressure control element 311. When the negative pressure suction cup 31 of the present invention adsorbs the blank, the suction cup surface 317 first contacts the blank. The air in the suction cup surface 317 is sucked away by the negative pressure control element 311. The pressure alarm element 316 detects the pressure difference between the suction cup surface 317 and the blank. If the pressure between the suction cup surface 317 and the blank is not within acceptable limits, the pressure alarm element 316 sends a stop signal to the negative pressure control element 311 and notifies the staff to check, so as to avoid the blank falling and being damaged when the negative pressure suction cup 31 is adsorbing and moving. If the pressure between the suction cup surface 317 and the blank is within acceptable limits, the two first cylinders 313 drive the two extrusion plates 315 to move closer to each other, and the two extrusion plates 315 clamp the air supply pipe 314 to close the air supply pipe 314 and stop the air supply. The two extrusion plates 315 lock the pressure between the suction cup surface 317 and the blank to prevent the negative pressure suction cup 31 from losing pressure and the blank falling due to the damage of the negative pressure control element 311 when the negative pressure suction cup 31 is adsorbing and moving.
[0036] like Figure 5 , Figure 6As shown, the impurity removal mechanism 42 includes a housing 421, an anhydrous ethanol tank 422, an electrical control box 423, a slide rail 424, a spray element 425, a water trough 426, a second set of sticky rollers 427, a vision detection element 428, and a first set of sticky rollers 429. The anhydrous ethanol tank 422 and the electrical control box 423 are both located outside the housing 421. The slide rail 424 is located inside the housing 421. The second set of sticky rollers 427 and the first set of sticky rollers 429 are connected to the slide rail 424. The vision detection element 428 is located on the side of the second set of sticky rollers 427. The spray element 425 is located above the slide rail 424 on the side near the first set of sticky rollers 429. The water trough 426 is below the spray element 425. In this invention, a motor is located on the side of the slide rail 424 near the electrical control box 423. The drive unit (not shown in the figure) drives the second dust-adhesive roller group 427 and the first dust-adhesive roller group 429 to move on the slide rail 424 via a motor drive. During the billet transport, the first dust-adhesive roller group 429 and the second dust-adhesive roller group 427 adsorb impurities on the billet surface. At the same time, the vision detection element 428 detects the second dust-adhesive roller group 427. If the second dust-adhesive roller group 427 has a lot of impurities, it means that the first dust-adhesive roller group 429 is no longer suitable for work. At this time, the first dust-adhesive roller group 429 is driven by the motor drive to move along the slide rail 424 into the cleaning area for cleaning (the cleaning area is below the spray element 425). The second dust-adhesive roller group 427 is driven by the motor drive to move to the initial position of the first dust-adhesive roller group 429 to adsorb impurities on the billet surface.
[0037] like Figure 5 , Figure 6As shown, the second sticky roller assembly 427 includes a sticky roller 4271, a connecting rod 4272, a second cylinder 4273, a limiting track 4274, and a limiting block 4275. The sticky roller 4271 is connected to the limiting block 4275. The limiting block 4275 and the second cylinder 4273 are connected through the connecting rod 4272. The limiting block 4275 is inside the limiting track 4274. The structure and internal arrangement of the first sticky roller assembly 429 are the same as those of the second sticky roller assembly 427. When the first sticky roller assembly 429 enters the cleaning area, the second cylinder 4273 in the first sticky roller assembly 429 drives the sticky roller 4271 in the first sticky roller assembly 429 to move towards the slide rail 424. At this time, the anhydrous ethanol in the anhydrous ethanol tank 422 is sprayed onto the first sticky roller assembly 429 by the spraying element 425. This process cleans the first set of sticky rollers 429. The anhydrous ethanol that flows down is discharged through the water tank 426. After the first set of sticky rollers 429 is cleaned, the second cylinder 4273 inside the first set of sticky rollers drives the sticky roller 4271 inside the first set of sticky rollers 429 to move away from the slide rail 424. Then, the motor drive device controls the first set of sticky rollers 429 to move to the initial position of the second set of sticky rollers 427. The first set of sticky rollers 429 is inspected by the vision detection element 428. When impurities are found on the first set of sticky rollers 429, it means that the second set of sticky rollers 427 is no longer suitable for work. At this time, the above steps are repeated. The motor drive device drives the second set of sticky rollers 427 to move along the slide rail 424 into the cleaning area for cleaning, while the first set of sticky rollers 429 is driven to move to the initial position.
[0038] like Figure 7 As shown, the mechanical gripper 44 includes a table frame 441, a mobile device 442, a motor 443, and a gripper head 444. The mobile device 442 is located above the table frame 441, and the motor 443 is located above the mobile device 442. The motor 443 is connected to the gripper head 444. When feeding begins, the motor 443 drives the mobile device 442 to move the gripper head 444 to the working position.
[0039] like Figure 8 As shown, the cutting mechanism 2 includes a base 21, a second fixing plate 22, a slider 23, a cutter 24, a porous ceramic plate 411, and a negative pressure adsorption device 412. The second fixing plate 22 is connected to the base 21, the slider 23 is connected to the second fixing plate 22, and the slider 23 is connected to the cutter 24. The porous ceramic plate 411 is located below the cutter 24 and on the negative pressure table 41. The negative pressure adsorption device 412 is located below the porous ceramic plate 411. During operation, the cutter 24 uses one of a roller cutter, a hot-pressing cutter, or an energy cutter for cutting. By adjusting the appropriate amplitude and frequency, problems such as debris can be effectively avoided. At the same time, the porous ceramic plate 411 is used to adsorb and fix the green blank during cutting. The debris generated during cutting is collected by the negative pressure adsorption device 412 below.
[0040] like Figure 9 As shown, the feeding mechanism 1 includes a first fixed plate 11, a feeding shaft 12 is provided on one side of the first fixed plate 11, a control box 13 is provided on the other side of the first fixed plate 11, a guide roller 15 is provided on the side of the feeding shaft 12, and a height detection element 14 is provided on the upper side of the first fixed plate 11. When feeding begins, the control box 13 drives the feeding shaft 12 to move and send out the blank. The blank moves along the guide roller 15 towards the negative pressure table 41. At the same time, the height detection element 14 starts to measure the height of the blank and controls the unwinding speed to prevent the problem of mismatch between the feeding and transmission speeds.
[0041] like Figure 10 As shown, the feeding basket 32 includes a fence 321 and a guide block 322. The fence 321 is located below the guide block 322. When the blank is cut and needs to be placed into the feeding basket 32, the guide block 322 limits the direction and angle of the blank entering the basket, so that all blanks are neatly placed into the feeding basket 32. The fence 321 fixes the guide block 322 and, together with the guide block 322, limits and protects the blanks that have been placed into the feeding basket 32.
[0042] like Figure 11 As shown, a support net 413 is provided above the negative pressure table 41, and a buffer net 414 is provided above the support net 413. The support net 413 is a Teflon net, polyester net, or metal mesh, etc., and the buffer net 414 is a polyester mesh, nylon net, or metal fine mesh, etc. During the transfer of the billet, the negative pressure table 41 provides a stable negative pressure so that the billet is adsorbed and fixed on the buffer net 414, effectively reducing problems such as indentation.
[0043] The working principle of this invention is as follows: During operation, the feeding shaft 12 feeds out the billet, which moves along the guide roller 15 towards the negative pressure table 41. Simultaneously, the height detection element 14 begins measuring the billet height, controlling the unwinding speed to prevent mismatch between the feeding and conveying speeds. When feeding begins, the negative pressure table 41 provides a stable negative pressure, causing the billet to be adsorbed and fixed on the buffer net 414, effectively reducing indentations and other problems. During billet conveying, the first dust-adhesive roller group 429 and the second dust-adhesive roller group 427 adsorb impurities on the billet surface. Simultaneously, the vision detection element 428 detects the second dust-adhesive roller group 427, identifying impurities on the second dust-adhesive roller group. When there are many impurities (427), it indicates that the state of the first dust roller group 429 is no longer suitable for operation. The first dust roller group 429 is then moved to the cleaning area for cleaning. After cleaning, the first dust roller group 429 moves to the initial position of the second dust roller group 427 and operates from there. The second dust roller group 429 then enters the position of the first dust roller group 427. The first dust roller group 429 is inspected by the vision detection element 428. The above steps are repeated. When the blank enters the cutting mechanism 2 for cutting, the cutter 24 effectively avoids problems such as debris by adjusting the amplitude and frequency. Simultaneously, a porous ceramic plate 411 is used to adsorb and fix the green blank during cutting. Raw debris is collected by the negative pressure adsorption device 412 below. After cutting, the negative pressure suction cup 31 adsorbs the cut blank, and then the blank is placed into the feeding basket 32 for storage through the operation of the transmission mechanism 33. During operation, the negative pressure control element 311 sucks away the air in the suction cup surface 317 to make the pressure reach the target pressure value. The pressure alarm element 316 detects whether the pressure between the suction cup surface 317 and the blank is qualified. When the pressure between the suction cup surface 317 and the blank is unqualified, the pressure alarm element 316 sends a stop signal to the negative pressure control element 311 and proceeds. An alarm is triggered to notify staff to inspect the billet and prevent it from falling and being damaged when the negative pressure suction cup 31 moves. When the pressure between the suction cup surface 317 and the billet is within acceptable limits, the two first cylinders 313 drive the two extrusion plates 315 to move closer to each other. The two extrusion plates 315 clamp the air supply pipe 314 to close it and stop the air supply. This locks the pressure between the suction cup surface 317 and the billet, preventing accidents. When the billet is placed into the unloading basket 32, the fence 321 and the guide block 322 limit and protect the billet already placed in the unloading basket 32.
[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
