Description

Technical Field

[0001] The invention belongs to the technical field of MLCC processing, and in particular relates to an MLCC stacking cutting device. Background Art

[0002] The stacking and cutting of MLCC is an important part of its manufacturing process. It can stack ceramic dielectric diaphragms with printed electrodes layer by layer and then cut them to form independent capacitor units. In conventional MLCC stacking and cutting, the cutting debris of the cut product will be sucked by a chip suction module that moves with the cutter. However, during the cutting process, as the cutter rotates, the cutter and the chip suction module move, the surrounding air flows, causing some of the cutting debris to randomly fall on the surface of the product, affecting the electrical performance and quality of the product. Summary of the invention

[0003] The object of the present invention is to provide an MLCC stack cutting device to solve the technical defects described in the background technology.

[0004] An MLCC stacking cutting device includes a bearing seat and a lifting module. The bearing seat is used to support and fix the product. The lifting module drives a lifting frame. The lifting frame is equipped with a cutting knife group and an exhaust seat. The cutting knife group is used to cut the product. The exhaust seat is equipped with an inner cover, an outer cover and an air outlet duct. The outer cover is sleeved outside the inner cover and there is a gap between the outer cover and the inner cover so that an air-permeable annular gap is formed between the opening of the outer cover and the opening of the inner cover. The air outlet duct is connected with the gap between the inner cover and the outer cover. The opening of the inner cover extends outward to contact the surface of the product. At the same time, there is a distance between the opening of the outer cover and the surface of the product so that the air-permeable annular gap can absorb cutting debris generated when cutting the product and fix the product by the airflow when absorbing the cutting debris.

[0005] Based on the above technical solution, the present invention achieves the following beneficial effects: 1. After the product to be cut is supported and fixed by the bearing seat, the lifting module drives the lifting frame to move. At this time, the lifting frame drives the cutting knife group to contact the product, so that the cutting knife group can cut the part to be cut of the product. At the same time, the lifting frame drives the opening of the inner cover to contact the surface of the product; 2. Since the outer cover is sleeved outside the inner cover and there is a gap between the outer cover and the inner cover, an air-permeable annular gap is formed between the opening of the outer cover and the opening of the inner cover. At this time, the air-permeable annular gap can be evenly distributed around the part to be ring-cut of the product, so that the cutting debris generated when the part to be ring-cut of the product is cut can be efficiently and stably absorbed by the air-permeable annular gap; 3. Since the air-through annular seams are evenly distributed around the part to be cut around the product, compared with the conventional chip suction module that moves with the cutter, the distribution area of ​​the chip suction port, the area of ​​the chip suction port and the position distribution of the chip suction port are increased, so that the cutting debris randomly left on the product surface can be effectively sucked together, thereby improving the performance and quality of the product; 4. Since the air outlet duct is connected to the gap between the inner cover and the outer cover, compared with the conventional chip suction module with a dust suction box, the present invention can effectively avoid the stacking of cutting chips in the chip suction module to cause secondary pollution; 5. Since the air outlet pipe is connected to the gap between the inner cover and the outer cover, and the air annular slit can be fixedly distributed around the part to be cut around the product, compared with the conventional chip suction module that moves with the cutter, the pipe connected to the air annular slit of the present invention will not cause obstruction to the moving cutter, so that the cutter can move 360 ​​degrees around the product; 6. Since the opening of the inner cover extends outward from the opening of the inner cover to contact the product, so that the opening of the inner cover can be used to contact the surface of the product, and there is a distance between the opening of the outer cover and the surface of the product, during the period of suction of the cutting debris through the air annular seam, the airflow entering the air annular seam can be used to fix the product, thereby achieving the fixation of the product without setting up power modules such as cylinders, thereby reducing the manufacturing cost of the equipment.

[0006] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0007] In some embodiments, the cutting knife group includes a circular cutting motor arranged on a lifting frame, the circular cutting motor drives a circular cutting belt, the circular belt is provided with a supporting shaping roller fixed on the lifting frame, so that the shape of the circular belt is the same as the part to be circular cut on the product, and the circular belt is provided with a plurality of cutting knives arranged in an array for sliding on the product; Based on the above technical features, the present invention further achieves the following beneficial effects: 1. By using a single circular cutting motor (power source) to drive the circular belt to drive several cutters to move synchronously, multiple parts of the product can be cut synchronously, thereby improving cutting efficiency and reducing the manufacturing product and volume of the equipment; 2. Since the air-permeable annular seams are evenly distributed around the parts to be cut around the product, when multiple cutters cut multiple parts of the product at the same time, the cutting debris generated by all the cutters when cutting the product can be removed stably and efficiently; 3. Since the air-permeable annular seams are evenly distributed around the part to be cut around the product, when multiple cutters are set to cut the product synchronously, there is no need to independently set a chip suction mechanism at the position corresponding to each cutter, thereby further reducing the manufacturing cost of the equipment. At the same time, it is also convenient to replace and install the cutter.

[0008] In some embodiments, the air-permeable annular slit is disposed below the product; based on the technical solution, the cutting debris can fall to the periphery of the air-permeable annular slit by its own weight, so that the air-permeable annular slit can absorb the cutting debris more efficiently.

[0009] In some embodiments, the air outlet pipe is provided with a switch valve, the support seat is provided with an empty chamber, the product is placed in the empty chamber for cutting, the lifting module is used to drive the lifting frame to cover the empty chamber to form a closed space, the empty chamber is connected to an air pumping pipe, the air pumping pipe is used to increase the air pressure in the closed space, so that after the air outlet pipe releases the pressure in the closed space, the high-pressure airflow generated by the pressure difference between the closed space and the outside world is used to bring the cutting debris into the air annular gap; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Before cutting the product, the lifting module drives the lifting frame cover to close to the empty chamber to form a closed space, and the air pressure is increased in the closed space through the air pumping pipe in advance, so that when cleaning the cutting debris generated by cutting the product, the switch valve of the air outlet pipe is controlled to open to instantly release the pressure in the closed space, and the high-pressure airflow generated by the pressure difference between the closed space and the outside world is used to bring the cutting debris to the air annular gap, so that the air annular gap can absorb the cutting debris, and the air outlet pipe can be connected to the collection box outside to realize the centralized collection of cutting debris; 2. Before cutting the product, the lifting module drives the lifting frame to close the empty chamber to form a closed space, and the air pressure is increased in the closed space through the air pumping pipe in advance, so that during the cutting process, the switch valve of the air outlet pipe is controlled to open to slowly and continuously release the air in the closed space, so that the cutting debris generated by the cutting knife group in the process of cutting the product can be adsorbed and collected through the air annular gap; 3. The air flow pressure for cleaning cutting debris can be conveniently adjusted by electrically controlling the switch valve.

[0010] In some embodiments, the empty chamber is provided with a pressure relief pipe, and the pressure relief pipe is provided with a one-way valve, so that after the air outlet pipe releases the pressure to the enclosed space, the air in the enclosed space can drive the air in another space through the pressure relief pipe to enter the enclosed space through inertia to hit the cutting debris and bring the cutting debris into the air annular gap when the air in the enclosed space flows out from the air outlet pipe; Based on the above technical solution, the present invention further achieves the following beneficial effects: By arranging a pressure-relief pipe in the empty chamber and providing a one-way valve in the pressure-relief pipe, at the moment when the pressure in the enclosed space is relieved to the same as the external air pressure, the air in the enclosed space can drive the air in another space into the enclosed space through the pressure-relief pipe through inertia when flowing out from the air outlet pipe. At this time, the air in the enclosed space will move as a whole. At this time, the air in the enclosed space will push the remaining cutting debris to move into the air annular gap, thereby relatively reducing the accumulation of cutting debris.

[0011] In some embodiments, the air chamber is provided with a pressure-relief pipe, which is connected to an air storage space, and the air flow rate of the pressure-relief pipe is less than the air flow rate of the air-passing annular slit. When the air-inflating pipe is used to increase the air pressure in the enclosed space, the air storage space is also increased to the same air pressure. After the air outlet pipe releases the pressure in the enclosed space, the air storage space can continuously send pressurized air to the enclosed space through the pressure-relief pipe for a period of time, so as to send the cutting debris in the enclosed space to the air-passing annular slit. Based on the above technical solution, the present invention further achieves the following beneficial effects: Since the empty chamber is connected to the air storage space through the pressure-relief pipe and the air flow rate of the pressure-relief pipe is less than the air flow rate through the air annular gap, when the switch valve of the air outlet pipe is opened to instantly relieve the pressure in the enclosed space, the high-pressure airflow generated by the pressure difference between the enclosed space and the outside world can be used to bring the cutting debris remaining in the enclosed space to the air annular gap in advance and send it away. Afterwards, the air storage space can supply pressurized air to the enclosed space through the pressure-relief pipe for a period of time, so as to continuously send the cutting debris generated in the process of cutting the product by the cutting knife group to the air annular gap.

[0012] In some embodiments, the pressure relief pipe is conical in shape and one end with a small diameter is located in the empty room, so that when the air storage space continuously delivers pressurized air to the enclosed space through the pressure relief pipe for a period of time, the pressure relief pipe can produce a throttling effect on the passing air, thereby cooling the air storage space and increasing the output air pressure; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Since the pressure relief pipe is conical in shape and the end with a small diameter is located in the empty room, the pressure relief pipe can produce a throttling effect on the air passing through, thereby increasing the air pressure input into the confined space by the pressure relief pipe, that is, it can reduce the volume of the air storage space and reduce the size of the equipment; 2. In addition, it is also possible to increase the duration of the compressed air delivered from the air storage space to the confined space through the pressure relief pipe under the same volume of the air storage space; 3. Since the pressure relief pipe can produce a throttling effect on the passing air, the temperature of the air entering the sealed space can be reduced, thereby cooling the cutting knife group and the product being cut.

[0013] In some embodiments, an air disturbance block is provided in the air chamber, and one end section of the air disturbance block is located next to a wall surface of the product. When the airflow supplied to the enclosed space by the pressure relief pipeline slides over the outer wall of the air disturbance block, an air vortex is generated at one end section of the air disturbance block to sweep the cutting debris on one wall surface of the product to the periphery of the product, so that the air passing annular gap located on the other wall surface of the product can absorb the cutting debris; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Through the setting of the air disturbance block, the air from the air storage space is transported to the enclosed space through the pressure relief pipe. When the air flows to the air-passing annular slit, part of the air flow slides through the side of the air disturbance block in advance. When the air flow moves to the cross section close to the first wall of the product, the air flow will generate an air vortex to hit the first wall of the product, so as to sweep the cutting debris on the wall of the product to the outside of the product. At this time, the air-passing annular slit on the other wall of the product absorbs the cutting debris around the product, so that the cutting debris can be effectively prevented from accumulating on the first wall of the product. 2. Since the air in contact with the product collides with the product and moves around the product in the form of an air vortex, it can effectively reduce the accumulation of the blown cutting debris in a corner compared to blowing the product and the cutting knife group directly in a single direction; 3. Compared with the direct blowing method to blow away the cutting debris generated in the process of cutting the product by the cutting knife group, the present invention effectively reduces the thrust of the air when pushing the cutting debris to move, thereby effectively preventing the blown cutting debris from scratching the product and other components in the confined space.

[0014] In some embodiments, a plurality of wind-disturbing blocks are arranged at intervals in the empty chamber; Based on the above technical solution, the air vortices generated by each wind disturbance block interfere with each other, making the air flow pattern in the enclosed space relatively chaotic, thereby further reducing the accumulation of cutting debris in a corner of the enclosed space.

[0015] In some embodiments, the air outlet of the air pumping pipe is located in the air storage space; based on the above technical solution, when the air pumping pipe increases the air pressure in the enclosed space and the air storage space, it can effectively prevent residual cutting debris from entering the air storage space.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 7 As shown, this specific embodiment provides an MLCC stacking cutting device, which includes a bearing seat 1 and a lifting module 2, the bearing seat 1 is used to support and fix the product 5, the lifting module 2 drives a lifting frame 21, the lifting frame 21 is equipped with a cutting knife group 3 and an exhaust seat 4, the cutting knife group 3 is used to cut the product 5, the exhaust seat 4 is equipped with an inner cover 41, an outer cover 42 and an air outlet pipe 43, the outer cover 42 is sleeved to the outside of the inner cover 41 and there is a gap with the inner cover 41, so that an air-through annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41, the air outlet pipe 43 is connected with the gap between the inner cover 41 and the outer cover 42, the opening of the inner cover 41 extends outward to contact the surface of the product 5, and at the same time, there is a distance between the opening of the outer cover 42 and the surface of the product 5, so that the air-through annular gap 44 can absorb the cutting debris generated when cutting the product 5 and fix the product 5 by the airflow when absorbing the cutting debris.

[0021] After the supporting base 1 supports and fixes the product 5 to be cut, the lifting module 2 drives the lifting frame 21 to move. At this time, the lifting frame 21 drives the cutting knife group 3 to contact the product 5, so that the cutting knife group 3 can cut the part of the product 5 to be cut. At the same time, the lifting frame 21 drives the opening of the inner cover 41 to contact the surface of the product 5.

[0022] Since the outer cover 42 is sleeved on the outside of the inner cover 41 and there is a gap between the outer cover 42 and the inner cover 41, an air-permeable annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41. At this time, the air-permeable annular gap 44 can be evenly distributed around the part to be ring-cut of the product 5, so that the cutting debris generated when cutting the part to be ring-cut of the product 5 can be efficiently and stably absorbed by the air-permeable annular gap 44.

[0023] In addition, since the air-permeable annular seam 44 is evenly distributed around the portion to be cut around the product 5, compared with the conventional chip suction module that moves following the cutter 34, by increasing the distribution area of ​​the chip suction port, the area of ​​the chip suction port and the position distribution of the chip suction port, the cutting debris randomly left on the surface of the product 5 can be effectively sucked together to improve the performance and quality of the product 5.

[0024] At the same time, since the air outlet duct 43 is connected to the gap between the inner cover 41 and the outer cover 42, compared with the conventional chip suction module with a dust suction box, the present invention can effectively avoid the stacking of cutting chips in the chip suction module to cause secondary pollution.

[0025] Furthermore, since the air outlet pipe 43 is connected to the gap between the inner cover 41 and the outer cover 42, and the air annular slit 44 can be fixedly distributed around the portion to be cut around the product 5, therefore, compared with the conventional chip suction module that moves with the cutter 34, the pipe connected to the air annular slit 44 of the present invention will not cause obstruction to the moving cutter 34, so that the cutter 34 can move 360 ​​degrees around the product 5.

[0026] At the same time, since the opening of the inner cover 41 extends outward from the opening of the inner cover 41 to contact the product 5, so that the opening of the inner cover 41 can be used to contact the surface of the product 5, and there is a distance between the opening of the outer cover 42 and the surface of the product 5, therefore, during the period of cutting debris absorption through the air annular gap 44, the airflow entering the air annular gap 44 can be used to fix the product 5, thereby achieving the fixation of the product 5 without setting up a power module such as a cylinder, thereby reducing the manufacturing cost of the equipment.

[0027] The air outlet pipe 43 may be selectively connected to a vacuum pump to drive the air around the product 5 to flow into the air annular gap 44 .

[0028] In some embodiments, the cutting knife group 3 includes a circular cutting motor 31 arranged on the lifting frame 21, and the circular cutting motor 31 drives a circular cutting belt 32. The circular belt is provided with a supporting shaping roller 33 fixed on the lifting frame 21, so that the shape of the circular belt is the same as the part to be circularly cut of the product 5, and the circular belt is provided with a plurality of cutting knives 34 arranged in an array for sliding on the product 5.

[0029] By driving a circular belt with a single circular cutting motor 31 (power source) to drive a plurality of cutters 34 to move synchronously, multiple parts of the product 5 can be cut synchronously, thereby improving the cutting efficiency and reducing the manufacturing product 5 and volume of the equipment.

[0030] Since the air-permeable annular slits 44 are evenly distributed around the portion to be cut around the product 5, when multiple cutters 34 simultaneously cut multiple portions of the product 5, the cutting debris generated when all the cutters 34 cut the product 5 can be stably and efficiently removed; in addition, since the air-permeable annular slits 44 are evenly distributed around the portion to be cut around the product 5, when multiple cutters 34 are set to cut the product 5 synchronously, there is no need to independently set a chip suction mechanism at the position corresponding to each cutter 34, thereby further reducing the manufacturing cost of the equipment and, at the same time, facilitating the replacement and installation of the cutter 34.

[0031] In some embodiments, the air-permeable annular slit 44 is disposed below the product 5 so that the cutting debris can fall to the periphery of the air-permeable annular slit 44 by its own weight, thereby enabling the air-permeable annular slit 44 to absorb the cutting debris more efficiently.

[0032] In some embodiments, the air outlet pipe 43 is provided with a switch valve 45, the supporting base 1 is provided with an empty chamber 11, the product 5 is located in the empty chamber 11 for cutting, the lifting module 2 is used to drive the lifting frame 21 to cover the empty chamber 11 to form an enclosed space 12, and the empty chamber 11 is connected to an air pumping pipe 13, and the air pumping pipe 13 is used to increase the air pressure in the enclosed space 12, so that after the air outlet pipe 43 relieves the pressure in the enclosed space 12, the cutting debris is brought into the air annular gap 44 by the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world.

[0033] Before cutting the product 5, the lifting module 2 drives the lifting frame 21 to cover the empty chamber 11 to form a closed space 12, and increases the air pressure in the closed space 12 in advance through the inflation pipe 13, so that when cleaning the cutting debris generated by cutting the product 5, the switch valve 45 of the air outlet pipe 43 is controlled to open to instantly relieve the pressure in the closed space 12, and the cutting debris is brought to the air annular gap 44 by the high-pressure airflow generated by the pressure difference between the closed space 12 and the outside world, so that the air annular gap 44 can absorb the cutting debris, and the cutting debris can be collected in a centralized manner by connecting the air outlet pipe 43 to the collection box of the outside world.

[0034] Before cutting the product 5, the lifting module 2 drives the lifting frame 21 to cover the empty chamber 11 to form an enclosed space 12, and pre-increases the air pressure in the enclosed space 12 through the inflation pipe 13, so that during the cutting process of the product 5, the switch valve 45 of the air outlet pipe 43 is controlled to open to slowly and continuously release the air in the enclosed space 12, thereby achieving the adsorption and collection of cutting debris generated by the cutting knife group 3 in the process of cutting the product 5 through the air annular gap 44.

[0035] In addition, the switch valve 45 can be electrically controlled to conveniently adjust the air flow pressure for cleaning the cutting debris.

[0036] In some embodiments, the empty chamber 11 is provided with a pressure-relief pipe 14, and the pressure-relief pipe 14 is provided with a one-way valve 141, so that after the air outlet pipe 43 relieves the pressure in the enclosed space 12, the air in the enclosed space 12 can drive the air in another space through the pressure-relief pipe 14 into the enclosed space 12 through inertia when flowing out from the air outlet pipe 43, and hit the cutting debris and bring the cutting debris into the air annular gap 44.

[0037] By providing a pressure-relief pipe 14 in the empty chamber 11, and the pressure-relief pipe 14 is provided with a one-way valve 141, at the moment when the confined space 12 is depressurized to the same as the external air pressure, the air in the confined space 12 can drive the air in another space through the pressure-relief pipe 14 into the confined space 12 through inertia when it flows out from the air outlet pipe 43. At this time, the air in the confined space 12 will move as a whole. At this time, the air in the confined space 12 will push the remaining cutting debris to move into the air annular gap 44, thereby relatively reducing the accumulation of cutting debris.

[0038] In some embodiments, the empty chamber 11 is provided with a pressure-relief pipe 14, which is connected to an air storage space 15. The air flow of the pressure-relief pipe 14 is smaller than the air flow through the air annular gap 44. When the inflation pipe 13 is used to increase the air pressure in the enclosed space 12, the air storage space 15 is also increased to the same air pressure. After the air outlet pipe 43 relieves the pressure in the enclosed space 12, the air storage space 15 can deliver pressurized air to the enclosed space 12 through the pressure-relief pipe 14 for a period of time, so as to deliver the cutting debris in the enclosed space 12 to the air annular gap 44.

[0039] Since the empty chamber 11 is connected to the air storage space 15 through the pressure-relief pipe 14, and at the same time, the air flow of the pressure-relief pipe 14 is less than the air flow of the air-passing annular gap 44, so that when the switch valve 45 of the air outlet pipe 43 is opened to instantly relieve the pressure in the enclosed space 12, the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris originally remaining in the enclosed space to the air-passing annular gap 44 in advance and send it away. Subsequently, the air storage space 15 can continuously send pressurized air to the enclosed space 12 through the pressure-relief pipe 14 for a period of time, so as to continuously send the cutting debris generated in the process of cutting the product 5 by the cutting knife group 3 to the air-passing annular gap 44.

[0040] In some embodiments, the pressure-relief pipe 14 is conical in shape and one end with a smaller diameter is located in the empty chamber 11. When the air storage space 15 delivers pressurized air to the enclosed space 12 through the pressure-relief pipe 14 for a period of time, the pressure-relief pipe 14 can produce a throttling effect on the passing air, thereby cooling the air storage space 15 and increasing the output air pressure.

[0041] Since the pressure-relief pipe 14 is conical and the end with a small diameter is located in the empty chamber 11, the pressure-relief pipe 14 can produce a throttling effect on the air passing through, thereby increasing the air pressure input into the enclosed space 12 by the pressure-relief pipe 14, that is, it is possible to reduce the volume of the air storage space 15 and reduce the volume of the equipment. In addition, it is also possible to increase the duration of the air storage space 15 delivering pressurized air to the enclosed space 12 through the pressure-relief pipe 14 under the same volume of the air storage space 15.

[0042] At the same time, since the pressure relief pipe 14 can produce a throttling effect on the passing air, the temperature of the air entering the sealed space can be reduced, thereby achieving cooling of the cutting knife group 3 and the cut product 5.

[0043] In some embodiments, a wind disturbance block 16 is provided in the empty chamber 11, and one end section of the wind disturbance block 16 is located next to a wall of the product 5. When the airflow supplied to the confined space 12 by the pressure relief pipe 14 slides over the outer wall of the wind disturbance block 16, an end section of the wind disturbance block 16 generates an air vortex to sweep the cutting debris on one wall of the product 5 to the outside of the product 5, so that the air annular gap 44 located on the other wall of the product 5 can absorb the cutting debris.

[0044] By setting the wind disturbance block 16, the air transported from the air storage space 15 to the enclosed space 12 through the pressure-relief pipe 14, in the process of flowing to the air-permeable annular slit 44, part of the air flow will slide through the side of the wind disturbance block 16 in advance. When the air flow moves to a section close to a wall of the product 5, the air flow will generate an air vortex to hit a wall of the product 5, so as to sweep the cutting debris on the wall of the product 5 to the outside of the product 5. At this time, the air-permeable annular slit 44 located on the other wall of the product 5 absorbs the cutting debris located around the product 5, thereby effectively preventing the cutting debris from accumulating on a wall of the product 5.

[0045] Since the air in contact with the product 5 collides with the product 5 and moves around the product 5 in the form of an air vortex, compared with directly blowing the product 5 and the cutting blade assembly 3 in a single direction, it can effectively reduce the accumulation of the blown cutting debris in a corner.

[0046] In addition, compared with the direct blowing method to blow away the cutting debris generated during the cutting process of the cutting knife group 3 cutting the product 5, the present invention effectively reduces the thrust of the air when pushing the cutting debris to move, thereby effectively preventing the blown cutting debris from scratching the product 5 and other components in the confined space 12.

[0047] In some embodiments, a plurality of wind disturbance blocks 16 are arranged at intervals in the empty chamber 11 .

[0048] The air vortices generated by each wind disturbance block 16 can interfere with each other, making the air flow pattern in the enclosed space 12 relatively chaotic, thereby further reducing the accumulation of cutting debris in a corner of the enclosed space 12.

[0049] In some embodiments, the air outlet of the air pumping pipe 13 is located in the air storage space 15. When the air pumping pipe 13 increases the air pressure in the enclosed space 12 and the air storage space 15, it can effectively prevent the residual cutting debris from entering the air storage space 15.

[0050] In some embodiments, the outer wall of the air storage space 15 is made of heat-conducting material, a condenser is provided on the outer wall of the compressed air, and a condenser connected to the condenser is installed in the enclosed space 12. The condenser is located next to the air outlet of the pressure-relief pipe 14 so that the air sent into the enclosed space 12 by the pressure-relief pipe 14 can pass through the condenser.

[0051] When the air pressure in the air storage space 15 decreases, the temperature of the air storage space 15 also decreases. At this time, the condenser transfers the cooling to the condenser to further cool the air sent into the enclosed space 12 by the pressure relief pipe 14, thereby further cooling the cutting knife group 3 and the cut product 5.

[0052] In order to further explain the MLCC stack cutting device described in this specific embodiment, the following examples are listed.

[0053] Example 1 like Figures 1 to 5 As shown, this embodiment provides an MLCC stacking cutting device, which includes a bearing seat 1 and a lifting module 2. The bearing seat 1 is used to support and fix the product 5. The lifting module 2 drives a lifting frame 21. The lifting frame 21 is equipped with a cutting knife group 3 and an exhaust seat 4. The cutting knife group 3 is used to cut the product 5. The exhaust seat 4 is equipped with an inner cover 41, an outer cover 42 and an air outlet pipe 43. The outer cover 42 is sleeved outside the inner cover 41 and there is a gap with the inner cover 41, so that an air-through annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41. The vacuum device is connected to the gap between the inner cover 41 and the outer cover 42 through the air outlet pipe 43. The opening of the inner cover 41 extends outward and contacts the surface of the product 5. At the same time, there is a gap between the opening of the outer cover 42 and the surface of the product 5, so that the air-through annular gap 44 can absorb the cutting debris generated when cutting the product 5 and fix the product 5 by the airflow when absorbing the cutting debris. The air-through annular gap 44 is set above the product 5.

[0054] The cutting knife group 3 includes a circular cutting motor 31 arranged on the lifting frame 21, and the circular cutting motor 31 drives a circular cutting belt 32. The circular belt is provided with a supporting shaping roller 33 fixed on the lifting frame 21 so that the shape of the circular belt is the same as the part to be circularly cut of the product 5. The circular belt is provided with a plurality of cutting knives 34 arranged in an array for sliding on the product 5.

[0055] The following is a working description of an MLCC stack cutting device mentioned in this embodiment.

[0056] After the supporting seat 1 supports and fixes the product 5 to be cut, the lifting module 2 drives the lifting frame 21 to move. At this time, the lifting frame 21 drives several cutters 34 to contact the product 5. At the same time, the lifting frame 21 drives the opening of the inner cover 41 to contact the surface of the product 5; thereafter, the circular cutting motor 31 drives the circular belt to drive several cutters 34 to slide synchronously on the part to be cut of the product 5, thereby cutting the part to be cut of the product 5. At the same time, the vacuum equipment draws the air around the product 5 into the air annular gap 44 through the air outlet pipe 43. At this time, the cutting debris generated when the cutting knife group 3 cuts the product 5 enters the air annular gap 44 along with the air flow around the product 5. At the same time, the airflow entering the air annular gap 44 further fixes the product 5 at the same time.

[0057] Example 2 like Figures 2 to 6 As shown, this embodiment provides an MLCC stack cutting device, which includes a supporting base 1 and a lifting module 2.

[0058] The support base 1 is provided with a hollow chamber 11 , and the product 5 is cut in the hollow chamber 11 .

[0059] The bearing seat 1 is used to support and fix the product 5. The lifting module 2 drives the lifting frame 21. The lifting frame 21 is equipped with a cutting knife group 3 and an exhaust seat 4. The cutting knife group 3 is used to cut the product 5. The exhaust seat 4 is equipped with an inner cover 41, an outer cover 42 and an air outlet pipe 43. The outer cover 42 is sleeved outside the inner cover 41 and there is a gap between the inner cover 41, so that an air-through annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41. The air outlet pipe 43 is connected to the gap between the inner cover 41 and the outer cover 42. The air outlet pipe 43 is provided with an air outlet, which is connected to the cutting debris collection box. The air outlet pipe 43 is provided with a switch valve 45. The opening of the inner cover 41 extends outward to contact the surface of the product 5. At the same time, there is a gap between the opening of the outer cover 42 and the surface of the product 5, so that the air-through annular gap 44 can absorb the cutting debris generated when cutting the product 5 and fix the product 5 by the airflow when absorbing the cutting debris. The air-through annular gap 44 is set below the product 5.

[0060] The lifting module 2 is used to drive the lifting frame 21 to cover the empty chamber 11 to form an enclosed space 12. The empty chamber 11 is connected to an air pumping pipe 13. The air pumping pipe 13 is used to increase the air pressure in the enclosed space 12. After the air outlet pipe 43 relieves the pressure in the enclosed space 12, the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris into the air annular gap 44.

[0061] The cutting knife group 3 includes a circular cutting motor 31 arranged on the lifting frame 21, and the circular cutting motor 31 drives a circular cutting belt 32. The circular belt is provided with a supporting shaping roller 33 fixed on the lifting frame 21 so that the shape of the circular belt is the same as the part to be circularly cut of the product 5. The circular belt is provided with a plurality of cutting knives 34 arranged in an array for sliding on the product 5.

[0062] The following is a working description of an MLCC stack cutting device mentioned in this embodiment.

[0063] After the supporting seat 1 supports and fixes the product 5 to be cut or places the product 5 to be cut on the opening of the inner cover 41, the lifting module 2 drives the lifting frame 21 to cover the empty chamber 11 to form a closed space 12. At this time, the lifting frame 21 drives a number of cutters 34 to contact the product 5; thereafter, the air pressure in the closed space 12 is increased in advance through the air pumping pipe 13; thereafter, the circular cutting motor 31 drives the circular belt to drive a number of cutters 34 to slide synchronously on the part to be cut of the product 5, thereby cutting the part to be cut of the product 5.

[0064] After the cutting of the to-be-cut part of the product 5 is completed, the switch valve 45 of the air outlet pipe 43 is controlled to open to instantly release the pressure of the enclosed space 12, so that the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris to the air annular slit 44, so that the air annular slit 44 can absorb the cutting debris, and the air outlet pipe 43 is used to collect the cutting debris in the collection box outside; Alternatively, during the process of cutting the to-be-cut portion of the product 5, the switch valve 45 of the air outlet pipe 43 is controlled to open, so that the air in the enclosed space 12 is slowly and continuously released, so that the cutting debris generated during the cutting of the product 5 by the cutting knife assembly 3 is adsorbed and collected through the air annular slit 44; Alternatively, during the process of cutting the part to be cut of the product 5, the switch valve 45 of the air outlet pipe 43 is controlled to be opened. At the same time, there is no need to increase the air pressure in the enclosed space 12 through the air pumping pipe 13 in advance. Instead, air is continuously supplied to the enclosed space 12 through the air pumping pipe 13, so that when the air flows to the air annular gap 44, the cutting debris is brought into the air annular gap 44.

[0065] In addition, during the period when the air enters the air-through annular slit 44, the airflow entering the air-through annular slit 44 further fixes the product 5 at the same time, thereby preventing the product 5 from shifting when the chips are cut.

[0066] Example 3 like Figures 2 to 6 As shown, this embodiment provides an MLCC stack cutting device, which includes a supporting base 1 and a lifting module 2.

[0067] The support seat 1 is provided with an empty chamber 11 , and the product 5 is cut in the empty chamber 11 . The empty chamber 11 is provided with a pressure-relief pipe 14 , and the pressure-relief pipe 14 is provided with a one-way valve 141 .

[0068] The bearing seat 1 is used to support and fix the product 5. The lifting module 2 drives the lifting frame 21. The lifting frame 21 is equipped with a cutting knife group 3 and an exhaust seat 4. The cutting knife group 3 is used to cut the product 5. The exhaust seat 4 is equipped with an inner cover 41, an outer cover 42 and an air outlet pipe 43. The outer cover 42 is sleeved outside the inner cover 41 and there is a gap between the inner cover 41, so that an air-through annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41. The air outlet pipe 43 is connected to the gap between the inner cover 41 and the outer cover 42. The air outlet pipe 43 is provided with an air outlet, which is connected to the cutting debris collection box. The air outlet pipe 43 is provided with a switch valve 45. The opening of the inner cover 41 extends outward to contact the surface of the product 5. At the same time, there is a gap between the opening of the outer cover 42 and the surface of the product 5, so that the air-through annular gap 44 can absorb the cutting debris generated when cutting the product 5 and fix the product 5 by the airflow when absorbing the cutting debris. The air-through annular gap 44 is set below the product 5.

[0069] The lifting module 2 is used to drive the lifting frame 21 to cover the empty chamber 11 to form an enclosed space 12. The empty chamber 11 is connected to an air pumping pipe 13. The air pumping pipe 13 is used to increase the air pressure in the enclosed space 12. After the air outlet pipe 43 relieves the pressure in the enclosed space 12, the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris into the air annular gap 44.

[0070] The cutting knife group 3 includes a circular cutting motor 31 arranged on the lifting frame 21, and the circular cutting motor 31 drives a circular cutting belt 32. The circular belt is provided with a supporting shaping roller 33 fixed on the lifting frame 21 so that the shape of the circular belt is the same as the part to be circularly cut of the product 5. The circular belt is provided with a plurality of cutting knives 34 arranged in an array for sliding on the product 5.

[0071] The following is a working description of an MLCC stack cutting device mentioned in this embodiment.

[0072] After the supporting seat 1 supports and fixes the product 5 to be cut or places the product 5 to be cut on the opening of the inner cover 41, the lifting module 2 drives the lifting frame 21 to cover the empty chamber 11 to form a closed space 12. At this time, the lifting frame 21 drives a number of cutters 34 to contact the product 5; thereafter, the air pressure in the closed space 12 is increased in advance through the air pumping pipe 13; thereafter, the circular cutting motor 31 drives the circular belt to drive a number of cutters 34 to slide synchronously on the part to be cut of the product 5, thereby cutting the part to be cut of the product 5.

[0073] After completing the cutting of the to-be-cut part of the product 5, the switch valve 45 of the air outlet pipe 43 is controlled to open to instantly relieve the pressure in the enclosed space 12, so that the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris to the air annular gap 44, so that the air annular gap 44 can absorb the cutting debris, and can pass through the air outlet pipe 43 and the collection box of the outside world. At the same time, after the air outlet pipe 43 relieves the pressure in the enclosed space 12, the air in the enclosed space 12 can drive the air in another space through the pressure relief pipe 14 to enter the enclosed space 12 through the air-slowing pipe 14 through inertia to hit the cutting debris and bring the cutting debris into the air annular gap 44.

[0074] In addition, during the period when the air enters the air-through annular slit 44, the airflow entering the air-through annular slit 44 further fixes the product 5 at the same time, thereby preventing the product 5 from shifting when the chips are cut.

[0075] Example 4 like Figures 2 to 6 ,and Figure 7 As shown, this embodiment provides an MLCC stack cutting device, which includes a supporting base 1 and a lifting module 2.

[0076] The support base 1 is provided with an empty chamber 11, and the product 5 is cut in the empty chamber 11. The empty chamber 11 is provided with a pressure relief pipe 14, and the pressure relief pipe 14 is connected to an air storage space 15. The pressure relief pipe 14 is tapered and one end with a small diameter is located in the empty chamber 11, and the air storage space 15 is provided with an air pumping pipe 13. A plurality of air disturbance blocks 16 are arranged at intervals in the empty chamber 11, and one end section of the air disturbance block 16 is located next to a wall surface of the product 5.

[0077] The bearing seat 1 is used to support and fix the product 5. The lifting module 2 drives a lifting frame 21. The lifting frame 21 is equipped with a cutting knife group 3 and an exhaust seat 4. The cutting knife group 3 is used to cut the product 5. The exhaust seat 4 is equipped with an inner cover 41, an outer cover 42 and an air outlet pipe 43. The outer cover 42 is sleeved to the outside of the inner cover 41 and there is a gap with the inner cover 41, so that an air-through annular gap 44 is formed between the opening of the outer cover 42 and the opening of the inner cover 41. The air outlet pipe 43 is connected with the gap between the inner cover 41 and the outer cover 42. The air outlet pipe 43 is provided with an air outlet, and the air outlet is connected to the cutting debris collection box. The air outlet pipe 43 is provided with a switch valve 45. The opening of the inner cover 41 extends outward to contact the surface of the product 5. At the same time, there is a gap between the opening of the outer cover 42 and the surface of the product 5, so that the air-through annular gap 44 can absorb the cutting debris generated when cutting the product 5 and fix the product 5 by the airflow when absorbing the cutting debris. The air flow rate of the pressure relief pipe 14 is less than the air flow rate of the air-through annular gap 44. The air-permeable annular slit 44 is arranged below the product 5 .

[0078] The lifting module 2 is used to drive the lifting frame 21 to cover the empty chamber 11 to form an enclosed space 12. The empty chamber 11 is connected to an air pumping pipe 13. The air pumping pipe 13 is used to increase the air pressure in the enclosed space 12. After the air outlet pipe 43 relieves the pressure in the enclosed space 12, the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris into the air annular gap 44.

[0079] The cutting knife group 3 includes a circular cutting motor 31 arranged on the lifting frame 21, and the circular cutting motor 31 drives a circular cutting belt 32. The circular belt is provided with a supporting shaping roller 33 fixed on the lifting frame 21 so that the shape of the circular belt is the same as the part to be circularly cut of the product 5. The circular belt is provided with a plurality of cutting knives 34 arranged in an array for sliding on the product 5.

[0080] The following is a working description of an MLCC stack cutting device mentioned in this embodiment.

[0081] After the supporting seat 1 supports and fixes the product 5 to be cut or places the product 5 to be cut on the opening of the inner cover 41, the lifting module 2 drives the lifting frame 21 to cover the empty chamber 11 to form a closed space 12. At this time, the lifting frame 21 drives a number of cutters 34 to contact the product 5; thereafter, the air pressure in the closed space 12 is increased in advance through the air pumping pipe 13, and the air storage space 15 is also increased to the same air pressure; thereafter, the circular cutting motor 31 drives the circular belt to drive a number of cutters 34 to slide synchronously on the part to be cut of the product 5, thereby cutting the part to be cut of the product 5.

[0082] Before the cutting of the to-be-cut part of the product 5 is completed, the switch valve 45 of the air outlet pipe 43 is controlled to open to instantly release the pressure of the enclosed space 12, so that the high-pressure airflow generated by the pressure difference between the enclosed space 12 and the outside world is used to bring the cutting debris to the air annular slit 44, so that the air annular slit 44 can absorb the cutting debris, and the air outlet pipe 43 is used to collect the cutting debris in the collection box outside; Subsequently, during the process of the cutter 34 cutting the to-be-cut portion of the product 5, the pressure-relief pipe 14 continuously delivers pressurized air to the enclosed space 12 for a period of time. At this time, the pressure-relief pipe 14 can produce a throttling effect on the passing air, thereby cooling the air storage space 15 and increasing the output air pressure. At the same time, the air storage space 15 delivers the air to the enclosed space 12 through the pressure-relief pipe 14. During the process of flowing to the air-transmitting annular slit 44, part of the air flow slides over the side of the wind-disturbance block 16 in advance. When the air flow moves to a cross-section close to a wall of the product 5, the air flow will generate an air vortex to hit a wall of the product 5, so as to sweep the cutting debris on the wall of the product 5 to the outside of the product 5. At this time, the air vortexes generated by each wind-disturbance block 16 interfere with each other, making the air flow pattern in the enclosed space 12 relatively chaotic. Finally, the air drives the cutting debris into the air-transmitting annular slit 44 together. The air and the cutting debris entering the air-transmitting annular slit 44 are collected through the air outlet pipe 43 and are collected in the collection box outside.

[0083] In addition, during the period when the air enters the air-through annular slit 44, the airflow entering the air-through annular slit 44 further fixes the product 5 at the same time, thereby preventing the product 5 from shifting when the chips are cut.
