Abstract

Technical Field
[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device based on ultrasonic high-frequency vibration technology. Background Technology
[0002] The battery separator is a membrane material between the positive and negative electrodes of a battery. It is a very critical part of the battery and has a direct impact on battery safety and cost. Its main functions are to isolate the positive and negative electrodes and prevent electrons in the battery from passing through freely, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes.
[0003] In existing technologies, when cutting the battery separator film multiple times, the cutting edge of the blade will wear down, and the ceramic powder coated on the surface of the battery separator film will stick to the cutting edge and the blade body surface, resulting in increased resistance at the cutting edge and reduced cutting force. This makes it easy for the cut of the battery separator film to be uneven in subsequent cutting processes, affecting the cutting effect. Therefore, we propose a new cutting device based on ultrasonic high-frequency vibration technology. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that the ceramic powder coated on the surface of the battery separator film will stick to the cutting edge and blade surface, reducing the cutting force and making the cut uneven in subsequent cutting processes, thus affecting the cutting effect. The invention proposes a cutting device based on ultrasonic high-frequency vibration technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device based on ultrasonic high-frequency vibration technology, comprising a blade, a fixed base, and a housing. The blade is disposed inside the fixed base. A heating resistor is disposed on the front surface of the fixed base. An adapter is fixedly connected to the top of the fixed base. An amplitude transformer is fixedly connected to the top of the adapter. A transducer is disposed at the bottom inner part of the housing. The output end of the transducer is fixedly connected to the amplitude transformer. A bracket is fixedly connected to the front surface of the housing. A temperature probe is disposed on the rear surface of the bracket.
[0006] Preferably, the bracket is bent near the bottom, and the distance between the temperature probe and the blade is maintained within 10mm.
[0007] Preferably, a cover is provided on the top of the housing, and a control panel is provided on the rear surface of the housing near the upper part of the bracket.
[0008] Preferably, a signal receiving block is provided on one side of the outer surface of the housing, and multiple heat dissipation holes are uniformly formed on the other side of the outer surface of the housing.
[0009] Preferably, an air pipe connector is provided on one side of the outer surface of the housing near the lower part of the signal receiving block, and the air pipe connector is connected to the housing.
[0010] Preferably, a plurality of locking screws are equidistantly arranged on the rear surface of the fixing seat, and the plurality of locking screws are threaded through the rear surface of the fixing seat and extend inward.
[0011] Preferably, the outer surface of the blade is in contact with the inner surface of the fixing seat, and the end face of the locking screw is in contact with the outer surface of the blade.
[0012] Preferably, a heat insulation ring is provided on the outer surface of the amplitude rod, and the top of the heat insulation ring is attached to the bottom of the outer shell.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, during use, the heating resistor and temperature probe work together to heat the blade and maintain it at a constant temperature. The signal receiving block receives external ultrasonic signals, which are processed by the control board. The transducer generates a resonant frequency consistent with the signal frequency, causing the heated blade to vibrate at high frequency. The movement of the blade relative to the separator membrane changes from a unidirectional displacement motion without ultrasound to a high-frequency reciprocating cutting motion. The cutting edge is smoother, the cutting force is smaller, and the high-frequency vibration of the blade can remove the ceramic powder adhering to the blade edge, ensuring the sharpness of the blade's cutting edge and avoiding frequent blade replacements. This greatly extends the life of the blade and improves the cutting effect of the battery separator membrane.
[0015] 2. In this utility model, during use, by setting a heat insulation ring between the amplitude rod and the outer shell, most of the heat can be reduced from being transferred upwards. After the air pipe joint is connected to the external air-cooling device, it is convenient for cold air to enter the outer shell to dissipate heat from the internal structure, and the internal hot airflow is discharged from multiple heat dissipation holes, preventing the outer shell and internal structure from overheating and affecting use, and the heat dissipation effect is good.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figures 1-4 As shown, this utility model provides a cutting device based on ultrasonic high-frequency vibration technology, including a blade 1, a fixed base 2, and a housing 5. The blade 1 is disposed inside the fixed base 2. A heating resistor 7 is disposed on the front surface of the fixed base 2. An adapter 3 is fixedly connected to the top of the fixed base 2, and an amplitude transformer 6 is fixedly connected to the top of the adapter 3. A transducer 13 is disposed at the bottom inner part of the housing 5, and the output end of the transducer 13 is fixedly connected to the amplitude transformer 6. A bracket 11 is fixedly connected to the front surface of the housing 5, and a temperature probe 10 is disposed on the rear surface of the bracket 11. The bracket 11 is bent near the bottom. The distance between the temperature probe 10 and the blade 1 is maintained within 10mm. A cover 14 is disposed on the top of the housing 5. A control plate 12 is disposed on the rear surface of the housing 5 near the upper part of the bracket 11. Multiple locking screws 15 are equidistantly disposed on the rear surface of the fixed base 2. The multiple locking screws 15 are threaded and rotate through the rear surface of the fixed base 2 and extend inward. The outer surface of the blade 1 is in contact with the inner surface of the fixed base 2, and the end face of the locking screw 15 is in contact with the outer surface of the blade 1.
[0024] The overall effect of Embodiment 1 is that, during battery separator cutting, the tungsten carbide blade 1 is placed inside the fixing seat 2 and secured with multiple locking screws 15, facilitating replacement. The control board 12 detects the surface temperature of the blade 1 through a temperature sensor 10 mounted on the surface of the bracket 11. The heat generated by the heating resistor 7 is transferred to the blade 1 through the fixing seat 2, raising its temperature to a specified level. When the temperature reaches the specified level, the temperature sensor 10 detects the temperature change and, through the circuit control board 12, disconnects the power supply to the heating resistor 7, stopping its operation. When the temperature drops to a certain level, the temperature sensor 10 detects the temperature change again, closing the circuit and allowing the heating resistor 7 to continue operating, thereby controlling the temperature between 50 and 60°C, achieving a constant temperature effect. After the ultrasonic generator and transducer 13 are powered on, the ultrasonic generator generates a periodic continuous signal. The signal emitted by the ultrasonic generator is received by the signal receiving block 8. After the control board 12 processes the signal, the transducer 13 converts it into a vibration that is consistent with the resonant frequency of the signal. This vibration is transmitted through the connected amplitude transformer 6 and adapter 3, causing the blade 1 in the fixed base 2 to generate high-frequency vibration. Combined with the heated blade 1, the movement of the blade 1 relative to the separator membrane changes from a unidirectional displacement motion without ultrasonic treatment to a high-frequency reciprocating cutting motion of the blade 1. The cutting edge is smoother, the cutting force is smaller, and the up-and-down vibration of the blade 1 can remove the ceramic powder adhering to the blade edge, preventing it from sticking to the blade and ensuring the sharpness of the cutting edge of the blade 1 at all times. This avoids the need for frequent blade replacement, greatly improves the service life of the tool, and results in a good cutting effect on the battery separator membrane.
[0025] Example 2: Figures 1-4 As shown, the only difference between this embodiment and embodiment 1 is that a signal receiving block 8 is provided on one side of the outer surface of the housing 5, and multiple heat dissipation holes 16 are evenly opened on the other side of the outer surface of the housing 5. An air pipe connector 9 is provided on one side of the outer surface of the housing 5 near the lower part of the signal receiving block 8. The air pipe connector 9 is connected to the housing 5. A heat insulation ring 4 is provided on the outer surface of the amplitude rod 6. The top of the heat insulation ring 4 is attached to the bottom of the housing 5.
[0026] The overall effect of embodiment 2 is that, during use, a heat insulation ring 4 is set between the amplitude rod 6 and the outer shell 5, which can reduce most of the heat transfer upward. The air pipe connector 9 is used to connect to the external air cooling device, which facilitates the entry of cold air into the outer shell 5 to dissipate heat from the internal structure, and allows the internal hot air to be discharged from multiple heat dissipation holes 16, preventing the outer shell 5 and the internal structure from overheating and affecting use, and the heat dissipation effect is good.
[0027] Working Principle: During battery separator cutting, a tungsten carbide blade 1 is placed inside a fixed base 2 and secured with multiple locking screws 15 for easy replacement. The control board 12 detects the surface temperature of the blade 1 via a temperature sensor 10 mounted on the support 11. The heat generated by the heating resistor 7 is transferred to the blade 1 through the fixed base 2, raising its temperature to a specified level. When the temperature reaches the specified level, the temperature sensor 10 detects the temperature change and, via the circuit control board 12, disconnects the power supply to the heating resistor 7, stopping its operation. When the temperature drops to a certain level, the temperature sensor 10 detects the temperature change again, closing the circuit and allowing the heating resistor 7 to continue operating, thus maintaining the temperature between 50 and 60°C, achieving a constant temperature. After the external ultrasonic generator and transducer 13 are powered on, the ultrasonic generator generates a periodic continuous signal. The signal emitted by the ultrasonic generator is received by the signal receiving block 8, controlling the operation. After the signal is processed by plate 12, it is converted into vibration by transducer 13, which is consistent with the resonant frequency of the signal. This vibration is transmitted through the connected amplitude transformer 6 and adapter 3, causing the blade 1 in the fixed base 2 to generate high-frequency vibration. Combined with the heated blade 1, the movement of the blade 1 relative to the separator membrane changes from the unidirectional displacement motion without ultrasonic treatment to the high-frequency reciprocating cutting motion of the blade 1. The cutting edge is smoother, the cutting force is smaller, and the up-and-down vibration of the blade 1 can remove the ceramic powder adhering to the blade edge, preventing it from sticking to the blade and ensuring the sharpness of the cutting edge of the blade 1 at all times. This avoids the need for frequent blade changes and greatly improves the service life of the tool. The cutting effect of the battery separator membrane is good. A heat insulation ring 4 is set between the amplitude transformer 6 and the outer shell 5, which can reduce most of the heat transfer upward. The air pipe connector 9 is used to connect the external air cooling device, which facilitates the entry of cold air into the outer shell 5 to dissipate heat from the internal structure and allows the internal hot air to be discharged from multiple heat dissipation holes 16, preventing the outer shell 5 and the internal structure from overheating and affecting the use. The heat dissipation effect is good.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
