[0002] As the core power source for modern electronic devices and new energy vehicles, the production quality of lithium batteries directly affects the performance and safety of the products. During the lithium battery production process, the electrode preparation stage generates a large number of charged particles ranging from micrometers to millimeters in size. If these charged particles are not effectively removed, they will cause a decline in battery performance and, in severe cases, even lead to internal short circuits. Therefore, effectively removing the dust generated during the production process is a crucial step in ensuring the quality and safety of lithium batteries.

[0003] Currently, electrostatic discharge and dust removal technologies commonly used in industrial production are mainly divided into two categories: contact and non-contact. Contact removal methods have high removal efficiency, but they are prone to introducing uncontrollable foreign matter on high-speed production lines, increasing the risk of product contamination and making them unsuitable for high-speed production scenarios. Non-contact removal methods mainly rely on a combination of airflow purging and electrostatic discharge, but they suffer from the problem of difficulty in controlling airflow balance: excessive airflow can cause electrode vibration, affecting product quality; insufficient airflow cannot effectively remove large dust particles, reducing the cleaning effect.

[0004] Existing devices that combine static electricity elimination and dust removal functions still have significant room for improvement in terms of adaptability and wind speed control precision, which severely restricts the improvement of dust removal efficiency and product quality in the lithium battery production process.

[0019] In view of the shortcomings of the prior art, the inventor of this utility model has, through long-term research and extensive practice, proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process, and its principles.

[0020] 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this specification, the references to terms such as "an embodiment," "a particular embodiment," or "the embodiment" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] This utility model provides a device for eliminating static electricity and dust. (See also...) Figure 1 The diagram shows a schematic of a device for eliminating static electricity and dust.

[0024] The device for eliminating static electricity and dust includes a static field strength monitor, a static elimination unit, and a dust collection unit.

[0025] An electrostatic field strength monitor is located in the target area to monitor the electrostatic intensity and polarity of dust particles in the area. An electrostatic eliminator unit is connected to and adjacent to the electrostatic field strength monitor. It generates a corresponding number of reverse ions based on the electrostatic intensity and polarity to neutralize and eliminate the static electricity in the dust. A suction and dust collection unit is located after the electrostatic eliminator unit along the dust flow direction. A dust concentration sensor is installed at its air inlet to adjust the suction power based on the dust concentration detected by the sensor, thereby adsorbing and collecting the dust after electrostatic elimination.

[0026] By linking electrostatic field strength monitoring with electrostatic elimination, the ion generation of the electrostatic elimination unit can be adjusted in real time for electrostatic fields of different polarities and intensities, effectively solving the problem of electrostatic adsorption of large particles in the lithium battery production process. By linking dust concentration monitoring with dust accumulation in the suction system, the number of large particles can be dynamically calculated and the suction power can be dynamically adjusted. This can effectively remove surface particles from target components (such as electrodes in the lithium battery production process) while avoiding electrode vibration caused by excessive wind speed.

[0027] In a preferred embodiment, the electrostatic field strength monitor includes multiple electric field sensors uniformly distributed within the target area, enabling comprehensive monitoring of the electrostatic field distribution in the target area environment. It should be noted that the electrostatic field strength monitor may also include only a single electric field sensor.

[0028] In a preferred embodiment, the static electricity elimination unit includes a high-voltage power supply, an ion generator, and a first fan. The high-voltage power supply is connected to the ion generator and is used to output a corresponding voltage to the ion generator according to the electrostatic intensity and polarity, so as to control the ion generator to produce a corresponding number of reverse ions. The first fan is used to transport the reverse ions to the target area.

[0029] In a preferred embodiment, the ion generator employs carbon fiber tip discharge technology to produce bipolar ions, and a first fan is used to transport the bipolar ions to the target area. The bipolar ions are composed of positive and negative ions in a certain proportion.

[0030] In a preferred embodiment, the device for eliminating static electricity and dust further includes a temperature and humidity monitor. The temperature and humidity monitor is located in the target area and connected to the static electricity elimination unit, and is used to monitor the temperature and humidity in the target area. The static electricity elimination unit is used to determine whether reverse ions are generated based on the temperature, humidity, and static electricity intensity.

[0031] For example, in low humidity environments, static electricity accumulates more easily, and the static elimination unit lowers the activation threshold, starting static elimination earlier when the static electricity intensity is small; in high humidity environments, static electricity does not accumulate easily, and the static elimination unit raises the activation threshold, starting static elimination only when the static electricity intensity is large, reducing unnecessary static elimination.

[0032] In a preferred embodiment, the suction and dust collection unit includes an adjustable suction subunit and a filter subunit, such as... Figure 2 As shown. The adjustable suction subunit is located on the air inlet side of the suction and dust collection unit, and is used to generate an adjustable suction force to draw the statically neutralized dust into the suction and dust collection unit. The filter subunit is located on the air outlet side of the suction and dust collection unit, and is used to filter, adsorb, and collect the dust entering the suction and dust collection unit. Specifically, the adjustable suction subunit generates an adjustable suction force based on the dust concentration monitored by the dust concentration sensor.

[0033] In a preferred embodiment, the filtration subunit includes a multi-stage filter arranged sequentially along the dust flow direction, with the minimum dust particle size that each stage of the filter can adsorb and collect decreasing progressively along the dust flow direction. The multi-stage filter can effectively capture dust particles of different sizes.

[0034] In a preferred embodiment, the multi-stage filter includes a primary filter, a secondary filter, and a high-stage filter arranged sequentially along the dust flow direction, forming a three-stage filter. The primary filter employs a metal mesh structure with a mesh pore size of 100μm to 200μm. The secondary filter uses non-woven fabric with a pore size of 5μm to 10μm. The high-stage filter is made of HEPA material and is used to adsorb and collect dust particles with a diameter greater than 0.3μm. The filtration efficiency of this three-stage filter is higher than 99.97%.

[0035] In a preferred embodiment, the suction-adjustable subunit includes a second fan and a third fan. The second fan generates a first airflow, along which the statically dissipated dust flows. The third fan generates a second airflow, which adjusts the direction and intensity of the first airflow. Through the coordinated operation of the second and third fans, a more uniform and directional airflow is formed, improving dust collection efficiency.

[0036] In a preferred embodiment, the air inlet of the suction dust collection unit is provided with an electrostatic eliminator, which is used to eliminate the static electricity generated by dust friction during the air intake process and prevent the dust from being adsorbed again.

[0037] In a preferred embodiment, a particle counter is set between the electrostatic elimination unit and the suction dust collection unit to dynamically measure the number of large particles and provide data support for subsequent suction power adjustment.

[0038] In a preferred embodiment, the suction and dust collection unit integrates a high-pressure device for collecting the sucked-in dust. Simultaneously, the high-pressure device generates positive and negative ions, which are discharged from the air outlet. Preferably, an ion deviation device is installed at the air outlet. When the ion deviation exceeds a preset value range, it is determined that there is excessive internal dust accumulation, prompting maintenance. By integrating the high-pressure device and the ion deviation device into the suction and dust collection unit, a complete closed-loop system is formed, which can automatically determine the maintenance timing of the suction and dust collection unit, improving the reliability and maintenance efficiency of the equipment.

[0039] This invention addresses the problem of ineffective removal of large amounts of micrometer-millimeter (µm-mm) particles during lithium battery production, leading to battery performance degradation and even internal short circuits. It also addresses the shortcomings of existing contact-based removal technologies, such as the introduction of uncontrollable foreign matter and unsuitability for high-speed applications, and the wind speed balance issues inherent in existing non-contact technologies. The invention provides a device for eliminating static electricity and dust. A static electricity field strength monitor is installed in the target area (e.g., at the process where large particles are generated) to determine the electrostatic polarity and field strength of the large particles. An electrostatic elimination unit is installed adjacent to the monitor, generating reverse ions based on the monitored electrostatic field strength and polarity, and dynamically controlling the number of ions generated according to the field strength. A suction and dust collection unit is installed after the electrostatic elimination unit to adsorb and collect the surface particles after static electricity elimination.

[0040] The technical solution of this utility model will be further described in detail below with reference to several preferred embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions.

[0041] Example 1

[0042] This embodiment provides a device for eliminating static electricity and dust, including a static field strength monitor, a static elimination unit, and a dust collection unit.

[0043] To facilitate the coordinated operation of the electrostatic field strength monitor, electrostatic elimination unit, and dust collection unit, an additional controller is included in the device to coordinate the work of each functional module. The controller employs a microprocessor architecture and includes a central processing unit, storage unit, input / output interfaces, and a communication unit. The communication unit supports multiple communication methods, facilitating data exchange with a host computer or other devices.

[0044] The controller's core logic is based on a real-time monitoring and response mechanism. It collects data from an electrostatic field strength monitor to determine the electrostatic field strength in the environment and triggers corresponding control mechanisms based on preset thresholds. The controller employs a layered architecture, including a hardware abstraction layer, a driver layer, a functional module layer, and an application layer. The hardware abstraction layer shields the underlying hardware differences, providing a unified interface; the driver layer handles the driver implementation for various external devices; the functional module layer implements the control logic for each functional module; and the application layer is responsible for overall coordination and human-machine interaction.

[0045] The controller also features self-diagnostic capabilities, enabling it to monitor the operational status of each module, including sensor, actuator, and communication status. When an anomaly is detected, the controller records the anomaly information and alerts the user via indicator lights or a display screen. Furthermore, the controller supports remote monitoring and parameter configuration; users can view the device's operational status and adjust control parameters through host computer software or a mobile application.

[0046] The controller's workflow is as follows: First, the controller initializes all hardware modules, including the electrostatic field strength monitor, the electrostatic elimination unit, and the suction and dust collection unit. Then, it enters the main loop, continuously collecting data from the electrostatic field strength monitor and comparing it with a preset threshold. When the field strength exceeds the threshold, the electrostatic elimination unit is triggered. Simultaneously, the controller adjusts the operating parameters of the electrostatic elimination unit based on the trend of the field strength change. In addition, the controller also controls the start / stop and operating intensity of the suction and dust collection unit based on the electrostatic elimination status, achieving coordinated control.

[0047] The electrostatic field strength monitor is the sensing unit of the entire device, responsible for real-time monitoring of the electrostatic field strength in the environment. The monitor employs an electric field sensor array design, including multiple electric field sensors distributed at different locations, enabling comprehensive monitoring of the electrostatic field distribution in the environment. Each electric field sensor uses a non-contact measurement principle, measuring the electrostatic field strength by detecting changes in charge caused by the electric field. The electric field sensors have a measurement range of 0–100 kV / m, a resolution of 0.1 kV / m, and a response time of less than 10 ms, meeting the monitoring requirements of rapidly changing environments.

[0048] The electrostatic field strength monitor's data acquisition circuit employs a 24-bit high-precision analog-to-digital converter with a sampling rate of 1kHz, enabling it to accurately capture minute changes in the electrostatic field. The data acquisition circuit also features anti-interference design, including analog filtering, digital filtering, and shielding measures, ensuring measurement accuracy in complex electromagnetic environments. After preprocessing, the acquired data is transmitted to the controller via a serial peripheral interface for subsequent analysis and decision-making.

[0049] The electrostatic field strength monitor also features self-calibration, enabling periodic zero-point and full-scale calibration to ensure measurement accuracy over long-term use. Furthermore, it supports fault detection; when the sensor or acquisition circuit malfunctions, it reports fault information to the controller for timely maintenance.

[0050] The static eliminator unit is one of the execution units of this device, responsible for eliminating static electricity in the environment. The static eliminator unit employs bipolar ion generation technology, generating positive and negative ions to neutralize the static charge on the surface of objects. The static eliminator unit includes a high-voltage power supply, an ion generator, and a first fan. The high-voltage power supply can generate ±7kV to drive the ion generator; the ion generator uses carbon fiber tip discharge technology to generate a large number of positive and negative ions; the first fan is responsible for transporting the generated ions to the target area.

[0051] The static eliminator unit operates in two modes: continuous mode and pulse mode. In continuous mode, the unit continuously generates ions, suitable for scenarios with rapid static accumulation. In pulse mode, the unit intermittently generates ions, suitable for scenarios with slow static accumulation, thus saving energy. The controller automatically selects the appropriate operating mode based on monitoring data from the static field strength monitor.

[0052] The static eliminator unit also features ion balance regulation, adjusting the generation ratio of positive and negative ions based on the distribution of positive and negative charges in the environment to ensure ion balance and prevent excessive elimination that could lead to charge polarity reversal. Furthermore, the static eliminator unit supports zone control, allowing for precise adjustment of the static elimination intensity in different areas based on their static conditions.

[0053] The suction and dust collection unit is another actuator in this device, responsible for absorbing and collecting dust from the environment. It employs a multi-stage filtration design, including a primary filter, a secondary filter, and a high-grade filter, effectively capturing dust particles of different sizes. The primary filter, using a metal mesh structure with pore sizes of 100μm–200μm, captures large dust particles. The secondary filter, using non-woven fabric, captures medium-sized dust particles with a filtration accuracy of 5μm–10μm. The high-grade filter, using HEPA material, captures very fine dust particles with a filtration accuracy of up to 0.3μm and a filtration efficiency greater than 99.97%.

[0054] The core of the dust collection unit is a high-efficiency centrifugal fan (i.e., an adjustable suction sub-unit), which generates strong negative pressure to create directional airflow. The maximum air volume of the high-efficiency centrifugal fan is 500m³ / s. 3 With a maximum static pressure of 2000Pa, it can meet the dust collection needs in various environments. The high-efficiency centrifugal fan adopts frequency conversion control, which can adjust the speed according to the dust level to achieve energy-saving operation.

[0055] The air inlet of the suction and dust collection unit is designed with an adjustable structure, allowing the size and direction of the inlet to be adjusted according to the needs of different areas. The air inlet is also equipped with an electrostatic eliminator, which can eliminate the frictional static electricity generated during the air intake process and prevent dust from being re-adsorbed.

[0056] The suction and dust collection unit also includes a dust collection subunit, which features a drawer-style design for easy cleaning and replacement. The dust collection subunit includes a dust collection box and a filter replacement indicator. When dust accumulates to a certain level or the filter needs replacement, the indicator will remind the user to perform maintenance.

[0057] The operating principle of the dust collection unit is as follows: First, the high-efficiency centrifugal fan starts and generates negative pressure; the negative pressure is transmitted to the air inlet through the pipe, forming suction; dust in the environment enters the pipe through the air inlet under the action of suction; the dust particles pass through the primary filter, the intermediate filter and the high-grade filter in sequence and are captured step by step; the filtered clean air is discharged from the air outlet, completing one dust collection cycle.

[0058] The suction and dust collection unit also features a self-cleaning function, which periodically reverse-airs the filter to extend its lifespan. During self-cleaning, the controller pauses suction, activates reverse airflow to blow dust adhering to the filter into the collection box, and then resumes normal suction.

[0059] The electrostatic field strength monitor, the electrostatic elimination unit, and the dust collection unit operate in conjunction with each other, and the working process is as follows.

[0060] The electrostatic field strength monitor continuously monitors the electrostatic field strength in the environment and transmits the data to the controller. The controller determines whether to activate the electrostatic elimination unit based on a preset threshold. When the detected electrostatic field strength exceeds the threshold, the controller activates the electrostatic elimination unit and adjusts the elimination intensity according to the field strength. For example, when the field strength is in the range of 5–20 kV / m, the electrostatic elimination unit operates at a low intensity; when the field strength is in the range of 20–50 kV / m, the unit operates at a medium intensity; and when the field strength exceeds 50 kV / m, the unit operates at a high intensity.

[0061] The controller predicts the rate of static electricity accumulation based on the changing trend of the electric field strength and adjusts the operating parameters of the static elimination unit in advance. For example, when a rapid increase in electric field strength is detected, the controller will increase the intensity of static elimination in advance to prevent static electricity from accumulating to a dangerous level; when a slow change in electric field strength is detected, the controller will appropriately reduce the intensity of static elimination to save energy consumption.

[0062] In addition, the controller adjusts the static elimination unit based on environmental factors such as temperature, humidity, and airflow. For example, in low-humidity environments, static electricity accumulates more easily, so the controller lowers the activation threshold and starts static elimination earlier; in high-humidity environments, static electricity does not accumulate easily, so the controller raises the activation threshold to reduce unnecessary static elimination.

[0063] The controller can also analyze historical data to predict the patterns of static electricity accumulation and elimination, and optimize the control of the static electricity elimination unit. The controller records the effectiveness of each static electricity elimination, including changes in field strength before and after elimination, elimination time, and energy consumption, and analyzes this data to find the optimal control parameters to improve the efficiency of static electricity elimination.

[0064] After static electricity is eliminated, dust on the object's surface loses its electrostatic attraction and is more easily carried away by airflow. The suction and dust collection unit generates directional airflow to draw floating dust into the collection box. Specifically, when the electrostatic field strength monitor detects that the electrostatic field strength exceeds the threshold, the controller activates the static electricity elimination unit to eliminate static electricity. After a period of static electricity elimination (e.g., 5-10 seconds), the controller activates the suction and dust collection unit to begin dust removal. After dust removal continues for a certain period (e.g., 20-30 seconds), the controller checks the field strength again to determine whether static electricity elimination and dust removal need to continue.

[0065] Furthermore, the timing of static electricity elimination and dust collection can be optimized to reduce unnecessary energy consumption. For example, when the electrostatic field strength is low, the static electricity elimination time can be reduced, and the dust collection unit can be started directly; when the electrostatic field strength is high, the static electricity elimination time can be extended to ensure that static electricity is fully eliminated before dust collection.

[0066] The device for eliminating static electricity and dust in this embodiment can efficiently eliminate static electricity and collect dust, improving the cleanliness and safety of the working environment. It is suitable for fields sensitive to static electricity and dust, such as electronics manufacturing, precision instruments, and medical equipment.

[0067] Example 2

[0068] This embodiment provides a device for eliminating static electricity and dust. Based on Embodiment 1, the suction and dust collection unit is optimized.

[0069] The operating principle of the suction and dust collection unit is the same as in Embodiment 1, but the design has been improved. This embodiment employs a dual-fan design, including a main fan and an auxiliary fan. The main fan is responsible for generating the primary suction force, while the auxiliary fan is responsible for adjusting the airflow direction and intensity. Through the coordinated operation of the two fans, a more uniform and directional airflow can be formed, improving dust collection efficiency.

[0070] The suction and dust collection unit also includes a dust concentration sensor, which can monitor the dust concentration in the intake airflow in real time. Based on the dust concentration data, the controller adjusts the speed of the main fan and auxiliary fan in the suction and dust collection unit, as well as the filter replacement cycle.

[0071] This device further improves the efficiency of static electricity elimination and dust collection, making it suitable for scenarios with higher requirements for static electricity and dust control.

[0072] Example 3

[0073] This embodiment provides a device for eliminating static electricity and dust. Based on Embodiment 1, the following optimized designs were made.

[0074] The controller employs a multi-core processor architecture, including a main processor and a coprocessor. The main processor handles overall control and decision-making, while the coprocessor handles data acquisition and preprocessing, improving the device's real-time performance and parallel processing capabilities. Furthermore, the controller incorporates cloud connectivity, enabling the uploading of operational data to a cloud platform for remote monitoring and big data analysis.

[0075] This embodiment employs a regional linkage strategy, dividing the work area into multiple sub-areas. Each sub-area is equipped with an independent electrostatic field strength monitor, electrostatic eliminator, and air intake. The controller independently controls the electrostatic elimination and dust extraction processes in each sub-area based on the electrostatic and dust conditions, achieving refined management.

[0076] Furthermore, this embodiment analyzes historical data to identify the optimal timing relationship between static electricity elimination and dust collection, thereby improving work efficiency. For example, in some areas, it may be necessary to perform static electricity elimination for a longer period before initiating dust collection; while in other areas, static electricity elimination and dust collection may need to be performed simultaneously or alternately.

[0077] The dust collection unit in this embodiment adopts a modular design, including multiple independent suction sub-units, each responsible for the dust collection of a sub-area. All suction sub-units are connected to a central filter via a main duct for centralized filtration and dust collection.

[0078] Furthermore, the dust collection unit in this embodiment also features an automatic adjustment function, which can automatically adjust the fan speed and filter replacement cycle according to the dust load. When a high dust concentration is detected in a certain area, the corresponding suction subunit will increase the fan speed to improve dust collection efficiency; when increased filter resistance is detected, it will remind the user to replace the filter or activate the self-cleaning program.

[0079] This device achieves more intelligent and efficient static electricity elimination and dust collection, and is suitable for complex environments such as large production lines or clean rooms.

[0080] Example 4

[0081] This embodiment provides a device for eliminating static electricity and dust. Based on Embodiment 1, the operating principle and overall structure of the suction dust collection unit have been optimized. Furthermore, the controller adopts a low-power design, including a sleep mode and a wake-up mechanism, to extend battery life.

[0082] In this embodiment, the suction and dust collection unit employs multi-stage separation technology, including two stages: cyclone separation and filtration separation. In the cyclone separation stage, airflow enters the cyclone separator, where large dust particles are thrown against the separator wall by centrifugal force and then fall into the collection box. In the filtration separation stage, airflow passes through a high-efficiency filter, capturing fine dust particles. This multi-stage separation design reduces the burden on the filter and extends its service life.

[0083] Furthermore, the dust collection unit in this embodiment features a compact design, integrating the fan, separator, and filter into a portable housing, with an overall weight kept below 3kg, making it easy to carry and use. The dust collection unit is also equipped with a retractable suction hose and various attachments to adapt to different dust collection needs.

[0084] The dust collection unit in this embodiment can also automatically adjust suction power, provide dust full load reminders, and monitor filter status. When a high dust concentration is detected, the dust collection unit will automatically increase suction power; when the dust collection box is close to full, the dust collection unit will remind the user to empty it; when the filter resistance increases, the dust collection unit will remind the user to replace the filter.

[0085] This device enables portable and highly efficient static elimination and dust collection, making it suitable for small spaces such as laboratories and offices, or for scenarios requiring mobile operation.
