Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a cutting device for ceramic green bodies. Background Art

[0002] Silicon nitride is a compound composed of silicon and nitrogen. It 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, higher melting point and lower thermal conductivity. These characteristics make silicon nitride have broad application prospects in many high-demand application scenarios, such as high-temperature engine components, cutting tools, high-temperature furnace tubes, integrated circuit substrates, etc. During the preparation of silicon nitride, the cast green body needs to be cut. There are two major problems with the cutting equipment currently on the market. First, the cutting adopts the hob method, which will produce a lot of debris when cutting the green body, polluting the green body surface. Second, the transmission method basically adopts the clamping green body transmission method, which will cause the green body surface to easily produce indentations and other problems.

[0003] Ceramic green bodies usually need to be cut after forming to meet the size and shape requirements of different products. Traditional cutting methods mostly use mechanical cutting or manual cutting, which has the following problems: low cutting accuracy, burrs or cracks are easily generated on the incisions, low cutting efficiency, and it is difficult to meet the needs of mass production. The green bodies are easily deformed or damaged during the cutting process, and the yield is low. Therefore, there is an urgent need for a high-precision, high-quality and automated production-suitable ceramic green body cutting method. Patent CN219599895U8 mentions a slitting device for a casting machine. The slitting knife used in this patent is a metal circular blade, which uses a shearing method to cut the green bodies. The metal circular blade will produce a large number of serrations when used to cut thick film green bodies, which will cause a large number of debris problems, and therefore cannot be used well on high thermal conductivity silicon nitride or aluminum nitride green bodies.

[0004] Conventional sticky rollers need to be manually replaced and cleaned after absorbing too many impurities, which consumes manpower and affects work efficiency. Therefore, a sticky roller system that can be automatically cleaned without stopping the machine is needed. Patent CN221602618U mentions an online cleaning system for sticky rollers. This patent adopts a four-roller coaxial rotation switching method to replace the sticky rollers. However, the blank cannot be cleaned when the sticky rollers are replaced, and some impurities will be missed and cannot be removed. At present, 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 fails. Therefore, a locking device that can protect the safety of the blank when the negative pressure suction cup fails is needed. Summary of the Invention

[0005] The object of the present invention is to provide a cutting device for ceramic green bodies to solve the problems raised in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the cutting device includes a discharge mechanism, a cutting mechanism, a blanking mechanism and a feeding mechanism, the blanking mechanism is arranged on the side of the feeding mechanism, the feeding mechanism includes a negative pressure platform, a large bracket is arranged under the negative pressure platform, and a dust removal mechanism is arranged on the side of the negative pressure platform. When working, the negative pressure platform adsorbs the ceramic blank, so that the blank is fixed on the negative pressure platform and is not easy to move unnecessarily. The dust removal mechanism also removes dust from the ceramic blank.

[0007] Furthermore, the unloading part 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 electric control system is provided on the side of the transmission mechanism, and a bracket is provided below the transmission mechanism.

[0008] Furthermore, the negative pressure suction cup includes a suction cup surface, a negative pressure control element is arranged above the suction cup surface, the negative pressure control element is connected to the suction cup surface through an air pipe, there is a first cylinder on both sides of the air pipe, each first cylinder is provided with an extrusion plate at one end close to the air pipe, a limiting slider is provided on both sides of each extrusion plate, and a pressure alarm element is provided on the side of the negative pressure control element. When the negative pressure suction cup in the present invention adsorbs the blank, the suction cup surface first contacts the blank, and the air in the suction cup surface is sucked away by the negative pressure control element, and the pressure between the suction cup surface and the blank is detected by the pressure alarm element. When the pressure between the suction cup surface and the blank is not up to standard, the pressure alarm component sends a stop signal to the negative pressure control component and issues an alarm to notify the staff to check, so as to avoid the blank from falling and being damaged when the negative pressure suction cup is sucking the blank and moving it. When the pressure between the suction cup surface and the blank is qualified, the two extrusion plates are driven close to each other by the two first cylinders, and the air pipe is clamped by the two extrusion plates so that the air pipe is closed and no longer ventilated. The pressure between the suction cup surface and the blank is locked by the two extrusion plates to prevent the negative pressure suction cup from losing pressure and the blank from falling due to damage of the negative pressure control component when the negative pressure suction cup is sucking the blank and moving it.

[0009] Furthermore, the impurity removal mechanism includes a housing, an anhydrous ethanol tank, an electrical control box, a slide rail, an injection element, a water flow trough, a second sticky roller group, a visual detection element, and a first sticky roller group. The anhydrous ethanol tank and the electrical control box are both on the outside of the housing, the slide rail is arranged on the inside of the housing, the second sticky roller group and the first sticky roller group are connected to the slide rail, the visual detection element is arranged on the side of the second sticky roller group, the injection element is arranged above the side of the slide rail close to the first sticky roller group, the water flow trough is below the injection element, and a motor drive device (not shown in the figure) is provided on the side of the slide rail close to the electrical control box in the present invention. The motor drive device drives the sticky roller group 2 and the sticky roller group 1 to move on the slide rail. When the blank is transmitted, the sticky roller group 1 and the sticky roller group 2 absorb impurities on the surface of the blank. At the same time, the visual detection element detects the sticky roller group 2. If there are many impurities in the sticky roller group 2, it means that the state of the sticky roller group 1 is no longer suitable for work. At this time, the motor drive device drives the sticky roller group 1 to move along the slide rail into the clean area for cleaning (the clean area is below the spray element). The motor drive device drives the sticky roller group 2 to move to the initial position of the sticky roller group 1 to absorb impurities on the surface of the blank.

[0010] Furthermore, the sticky roller group 2 includes a sticky roller, a connecting rod, a second cylinder, a limiting rail, and a limiting block. The sticky roller is connected to the limiting block, and the limiting block is connected to the second cylinder through a connecting rod. The limiting block is inside the limiting rail. The structure and internal arrangement of the sticky roller group 1 are the same as those of the sticky roller group 2. When the sticky roller group 1 enters the cleaning area, the second cylinder in the sticky roller group 1 drives the sticky roller in the sticky roller group 1 to move toward the slide rail. At this time, the anhydrous ethanol in the anhydrous ethanol tank is sprayed onto the sticky roller group 1 through the spray element, thereby cleaning the sticky roller group 1. The flowing anhydrous ethanol is discharged through the water trough. After the sticky roller group 1 is cleaned, the second cylinder inside the sticky roller group 1 drives the sticky roller inside the sticky roller group 1 to move away from the slide rail, and then the motor drive device controls the sticky roller group 1 to move to the initial position of the sticky roller group 2 for operation. The sticky roller group 1 is inspected by the visual detection element. When impurities are found on the sticky roller group 1, it means that the state of the sticky roller group 2 is no longer suitable for work. At this time, the above steps are repeated, and the motor drive device drives the sticky roller group 2 to move along the slide rail into the cleaning area for cleaning, and at the same time drives the sticky roller group 1 to move to the most initial position.

[0011] Furthermore, the mechanical gripper includes a table frame, a moving device, a motor, and a claw head. The moving device is arranged above the table frame, and the motor is arranged above the moving device. The motor and the claw head are connected. When feeding starts, the motor drives the moving device to move the mechanical gripper to the working position to work.

[0012] Furthermore, the cutting mechanism includes a base, a second fixed plate, a slider, a tool, 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 tool. The porous ceramic plate is arranged below the tool and is located on the negative pressure platform. A negative pressure adsorption device is provided below the porous ceramic plate. During operation, the tool is selected to use one of a rolling cutter, a hot pressing punching cutter or an energy cutter for cutting. By adjusting to the appropriate amplitude and frequency, problems such as debris can be effectively avoided. At the same time, a porous ceramic plate is used to adsorb and fix the green body during cutting, and the debris generated during cutting is collected by the negative pressure adsorption device below.

[0013] Furthermore, the unloading mechanism includes a first fixed plate, a unloading shaft is provided on one side of the first fixed plate, a control electrical box is provided on the other side of the first fixed plate, a guide roller is provided on the side of the unloading shaft, and a height detection element is provided on the upper side of the first fixed plate. When unloading starts, the control electrical box drives the unloading shaft to operate and send the blank out. The blank moves along the guide roller toward the negative pressure platform. At the same time, the height detection element starts to measure the height of the blank to control the unwinding speed and prevent the problem of mismatch between unloading and transmission speed.

[0014] Furthermore, the unloading basket includes a fence and a guide block. The fence is arranged on the lower side of the guide block. When the blank is cut and needs to be placed in the unloading basket, the guide block limits the direction and angle of the blank entering the basket, so that all the blanks are placed in the unloading basket in an orderly manner. The fence fixes the guide block and, together with the guide block, limits and protects the blanks placed in the unloading 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 a Teflon net, a polyester net or a metal mesh, etc., and the buffer net is a polyester mesh, a nylon net or a metal fine mesh, etc. When the blank is transmitted, the negative pressure platform provides a stable negative pressure so that the blank is adsorbed and fixed on the buffer net, effectively reducing problems such as indentation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The adsorption transmission mechanism consists of a support net and a buffer net. The support net is made of Teflon net, polyester net or metal mesh, and the buffer net is made of polyester mesh, nylon net or metal fine mesh. The negative pressure transmission method can effectively reduce problems such as indentation. The use of a hob, hot press punch cutter or energy knife for cutting and adjusting the appropriate amplitude and frequency can effectively avoid problems such as debris. When the green body is transferred, negative pressure transmission is adopted, and the claw head clamps the conveyor net for transmission. In this way, the angle and size of the cut green body are highly accurate. The multi-porous negative pressure suction cup for blanking is equipped with a sponge, PU foam or EVA foam buffer layer to protect the surface of the green porcelain and prevent adsorption marks during transfer.

[0018] 2. The negative pressure suction cup provided in the present invention has an automatic locking function, that is, a first cylinder and an extrusion plate are respectively provided on both sides of the air transmission pipe. Through the cooperation of the two first cylinders and the two extrusion plates, the negative pressure suction cup can be in a vacuum locking state after adsorbing the blank. When a fault occurs somewhere in the negative pressure suction cup, the vacuum state of the negative pressure suction cup will not be destroyed, thereby preventing the blank from falling off and being damaged. At the same time, a pressure alarm element is provided behind the negative pressure suction cup. When it is detected that the negative pressure suction cup has no suction, an alarm is triggered to avoid further losses and notify the staff to carry out maintenance.

[0019] 3. The impurity removal mechanism provided in the present invention has an automatic cleaning function, wherein a sticky roller group 1 and a sticky roller group 2 are provided, and the sticky roller group 2 is located behind the sticky roller group 1. Under normal conditions, the sticky rollers in the sticky roller group 1 and the sticky roller group 2 work simultaneously to remove impurities on the blank in two steps. A visual detection element is provided at the sticky roller group 2. When impurities are detected on the surface of the sticky roller group 2, it indicates that the sticky roller group 1 is not suitable for work, and the sticky roller group 1 enters the cleaning device for cleaning. After the sticky roller group 1 is cleaned, it enters the position of the original sticky roller group 2 to work, and the sticky roller group 2 enters the position of the original sticky roller group 1 to work. This can ensure that at least one sticky roller is in working condition while removing impurities without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts 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 discharge mechanism 1, a cutting mechanism 2, a blanking mechanism 3 and a feeding mechanism 4. The blanking mechanism 3 is arranged on the side of the feeding mechanism 4, and the feeding mechanism 4 includes a negative pressure platform 41. A large bracket 43 is arranged below the negative pressure platform 41, and a dust removal mechanism 42 is arranged on the side of the negative pressure platform 41. A mechanical clamp 44 is arranged on the other side of the dust removal mechanism 42. When working, the negative pressure platform 41 adsorbs the ceramic blank, so that the blank is fixed on the negative pressure platform 41 and is not easy to move unnecessarily. The dust removal mechanism 42 removes dust from 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 electronic 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, and a negative pressure control element 311 is arranged above the suction cup surface 317. The negative pressure control element 311 is connected to the suction cup surface 317 through an air supply pipe 314. There is a first cylinder 313 on both sides of the air supply pipe 314, and each first cylinder 313 is provided with an extrusion plate 315 at one end close to the air supply pipe 314. A limiting slider 312 is provided on both sides of each extrusion plate 315, and a pressure alarm element 316 is provided on the side of the negative pressure control element 311. When the negative pressure suction cup 31 in the present invention adsorbs the blank, the suction cup surface 317 first contacts the blank, and 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 gap between the suction cup surface 317 and the blank. Whether the pressure is qualified. When the pressure between the suction cup surface 317 and the blank is unqualified, the pressure alarm component 316 sends a stop signal to the negative pressure control component 311 and issues an alarm to notify the staff to check, so as to avoid the blank from falling and being damaged when the negative pressure suction cup 31 is moving while adsorbing the blank. When the pressure between the suction cup surface 317 and the blank is qualified, the two first cylinders 313 drive the two extrusion plates 315 to approach each other, and the two extrusion plates 315 clamp the air pipe 314 so that the air pipe 314 is closed and no longer ventilated. The pressure between the suction cup surface 317 and the blank is locked by the two extrusion plates 315 to prevent the negative pressure suction cup 31 from losing pressure and the blank from falling due to damage of the negative pressure control component 311 when the negative pressure suction cup 31 is moving while adsorbing the blank.

[0036] like Figure 5 、 Figure 6As shown, the impurity removal mechanism 42 includes a housing 421, an anhydrous ethanol tank 422, an electric control box 423, a slide rail 424, an injection element 425, a water flow trough 426, a sticky roller group 2 427, a visual detection element 428, and a sticky roller group 1 429. The anhydrous ethanol tank 422 and the electric control box 423 are both on the outside of the housing 421, the slide rail 424 is arranged on the inside of the housing 421, the sticky roller group 2 427 and the sticky roller group 1 429 are connected to the slide rail 424, the visual detection element 428 is arranged on the side of the sticky roller group 2 427, the injection element 425 is arranged above the side of the slide rail 424 close to the sticky roller group 1 429, the water flow trough 426 is below the injection element 425, and the side of the slide rail 424 close to the electric control box 423 is provided with a motor The driving device (not shown in the figure) drives the sticky roller group 2 427 and the sticky roller group 1 429 to move on the slide rail 424 through the motor driving device. When the blank is transmitted, the sticky roller group 1 429 and the sticky roller group 2 427 adsorb impurities on the surface of the blank. At the same time, the visual detection element 428 detects the sticky roller group 2 427. When it is found that there are many impurities in the sticky roller group 2 427, it means that the state of the sticky roller group 1 429 is no longer suitable for work. At this time, the motor driving device drives the sticky roller group 1 429 to move along the slide rail 424 into the cleaning area for cleaning (the cleaning area is below the injection element 425). The motor driving device drives the sticky roller group 2 427 to move to the initial position of the sticky roller group 1 429 to adsorb impurities on the surface of the blank.

[0037] like Figure 5 、 Figure 6As shown, the second sticky roller group 427 includes a sticky roller 4271, a connecting rod 4272, a second cylinder 4273, a limiting rail 4274, and a limiting block 4275. The sticky roller 4271 is connected to the limiting block 4275, and the limiting block 4275 is connected to the second cylinder 4273 through the connecting rod 4272. The limiting block 4275 is inside the limiting rail 4274. The structure and internal arrangement of the sticky roller group 1 429 are the same as those of the second sticky roller group 427. When the sticky roller group 1 429 enters the cleaning area, the second cylinder 4273 in the sticky roller group 1 429 drives the sticky roller 4271 in the sticky roller group 1 429 to move toward the direction close to the slide rail 424. At this time, the anhydrous ethanol in the anhydrous ethanol tank 422 is sprayed onto the sticky roller group 1 429 through the spray element 425. This cleans the sticky roller group 1 429, and the flowing anhydrous ethanol is discharged through the water trough 426. After the sticky roller group 1 429 is cleaned, the second cylinder 4273 inside the sticky roller group 1 drives the sticky roller 4271 inside the sticky roller group 1 429 to move away from the slide rail 424, and then the motor drive device controls the sticky roller group 1 429 to move to the initial position of the sticky roller group 2 427 to work. The sticky roller group 1 429 is inspected by the visual detection element 428. When impurities are found on the sticky roller group 1 429, it means that the state of the sticky roller group 2 427 is no longer suitable for work. At this time, the above steps are repeated, and the motor drive device drives the sticky roller group 2 427 to move along the slide rail 424 into the cleaning area for cleaning, and at the same time drives the sticky roller group 1 429 to move to the most 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 claw head 444. The mobile device 442 is arranged above the table frame 441, and the motor 443 is arranged above the mobile device 442. The motor 443 is connected to the claw head 444. When feeding starts, the motor 443 drives the mobile device 442 to move the claw head 444 to the working position for operation.

[0039] like Figure 8 As shown, the cutting mechanism 2 includes a base 21, a second fixed plate 22, a slider 23, a tool 24, a porous ceramic plate 411, and a negative pressure adsorption device 412. The second fixed plate 22 is connected to the base 21, the slider 23 is connected to the second fixed plate 22, the slider 23 and the tool 24 are connected to each other, the porous ceramic plate 411 is arranged below the tool 24 and is located on the negative pressure platform 41, and a negative pressure adsorption device 412 is provided below the porous ceramic plate 411. During operation, the tool 24 uses a rolling cutter, a hot pressing punching cutter or an energy cutter for cutting. By adjusting to 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 body during cutting, and the debris generated during cutting is collected by the negative pressure adsorption device 412 below.

[0040] like Figure 9 As shown, the unloading mechanism 1 includes a first fixed plate 11, a unloading shaft 12 is arranged on one side of the first fixed plate 11, a control electric box 13 is arranged on the other side of the first fixed plate 11, a guide roller 15 is arranged on the side of the unloading shaft 12, and a height detection element 14 is arranged on the upper side of the first fixed plate 11. When unloading starts, the control electric box 13 drives the unloading shaft 12 to move to send the blank out, and the blank moves along the guide roller 15 toward the negative pressure platform 41. At the same time, the height detection element 14 starts to measure the height of the blank to control the unwinding speed and prevent the problem of mismatch between unloading and transmission speed.

[0041] like Figure 10 As shown, the unloading basket 32 includes a fence 321 and a guide block 322. The fence 321 is arranged on the lower side of the guide block 322. When the blank is cut and needs to be placed in the unloading basket 32, the guide block 322 limits the direction and angle of the blank entering the basket, so that all the blanks are placed in the unloading basket 32 in an orderly manner. The fence 321 fixes the guide block 322, and at the same time, together with the guide block 322, limits and protects the blanks placed in the unloading basket 32.

[0042] like Figure 11 As shown, a support net 413 is provided above the negative pressure platform 41, and a buffer net 414 is provided above the support net 413. The support net 413 is a Teflon net, a polyester net or a metal mesh, etc., and the buffer net 414 is a polyester mesh, a nylon net or a metal fine mesh, etc. When the blank is transmitted, the negative pressure platform 41 provides a stable negative pressure so that the blank is adsorbed and fixed on the buffer net 414, effectively reducing problems such as indentation.

[0043] The working principle of the present invention is as follows: when working, the unwinding shaft 12 sends out the blank, and the blank moves along the guide roller 15 toward the negative pressure platform 41. At the same time, the height detection element 14 starts to measure the height of the blank, controls the unwinding speed, and prevents the problem of mismatch between the unwinding and transmission speeds. When the feeding starts, the negative pressure platform 41 provides a stable negative pressure so that the blank is adsorbed and fixed on the buffer net 414, effectively reducing problems such as indentation. During the transmission of the blank, the sticky roller group 1 429 and the sticky roller group 2 427 adsorb impurities on the surface of the blank. At the same time, the visual detection element 428 detects the sticky roller group 2 427 and finds that the sticky roller group 2 When there are too many impurities in 427, it means that the state of the sticky roller group 1 429 is no longer suitable for work, so the sticky roller group 1 429 is moved to the cleaning area for cleaning. After cleaning, the sticky roller group 1 429 moves to the initial position of the sticky roller group 2 427 to work, and the sticky roller group 2 429 enters the position of the sticky roller group 1 427 to work. The sticky roller group 1 429 is detected by the visual detection element 428. The above steps are repeated. When the blank enters the cutting mechanism 2 for cutting, the tool 24 effectively avoids problems such as debris by adjusting to the appropriate amplitude and frequency. At the same time, the porous ceramic plate 411 is used to adsorb and fix the blank during cutting, and the blank is produced during cutting. The raw debris is collected by the negative pressure adsorption device 412 below. When the cutting is completed, the negative pressure suction cup 31 adsorbs the cut blank, and then the blank is placed in the unloading 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 through the negative pressure control element 311 to make the pressure reach the target pressure value, and detects whether the pressure between the suction cup surface 317 and the blank is qualified through the pressure alarm element 316. 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 performs The alarm is triggered to notify the staff to conduct an inspection to prevent the blank from falling and being damaged when the negative pressure suction cup 31 is sucking the blank and moving it. When the pressure between the suction cup surface 317 and the blank is qualified, the two first cylinders 313 drive the two extrusion plates 315 to approach each other, and the two extrusion plates 315 clamp the air pipe 314 so that the air pipe 314 is closed and no longer ventilated, so that the pressure between the suction cup surface 317 and the blank is locked to prevent accidents. When the blank is placed in the blanking basket 32, the fence 321 and the guide block 322 limit and protect the blank placed in the blanking 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 embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
