Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tool processing, in particular to a method for adjusting oil mist concentration of a machine tool, an oil mist concentration adjusting system of a machine tool, a computer readable storage medium and an electronic device. BACKGROUND

[0002] In modern machine tool processing, in order to improve the surface quality and processing efficiency of workpieces, cooling liquid or lubricating oil is usually used to reduce friction and heat accumulation during cutting. Especially in high-speed and heavy-load cutting operations, the generation of oil mist is inevitable. These oil mists not only pollute the working environment and reduce air quality, but also may potentially harm the health of operators.

[0003] Traditional oil mist collection systems usually use adsorption or filtration methods to remove oil mist particles in the air. However, the efficiency and adaptability of these systems are often limited by design and operation methods, and cannot achieve the best oil mist removal effect under different processing conditions.

[0004] Most existing oil mist collectors use a motor-driven fan to form air flow to suck oil mist into a filtering device. The rotation speed of the motor and the air volume directly affect the collection efficiency of oil mist. However, traditional systems usually use fixed air volume and motor rotation speed, which cannot dynamically adjust the collection efficiency according to the processing load or actual operating conditions, which may result in poor collection effect, even oil mist overflow or accumulation. In addition, excessive air volume and motor rotation speed will cause energy waste and noise increase, while insufficient air volume will result in incomplete oil mist collection, thereby affecting the air quality in the workshop.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Figure 2 is a flowchart of the method of adjusting the oil mist concentration of a machine tool according to an embodiment of the present application. As Figure 2 shown, the method includes the following steps:

[0034] Step S201, a first acquisition step: acquiring the oil mist concentration in the machine tool processing environment to obtain a detected oil mist concentration.

[0035] In a specific implementation, step S201: an optical sensor is installed in the above machine tool processing environment, wherein the oil mist concentration in the machine tool processing environment is acquired to obtain a detected oil mist concentration, including:

[0036] ​Step S2011: obtaining light intensity data sensed by the photoelectric sensor;

[0037] Step S2012: processing the light intensity data to obtain corresponding current data;

[0038] Step S2013: determining the detected oil mist concentration corresponding to the current data, wherein a correspondence between the current data and the detected oil mist concentration is established in advance;

[0039] The photoelectric sensor detects light signals, which need to be converted into electrical signals, specifically current data, for subsequent processing. Then, the detected oil mist concentration is determined according to the current data.

[0040] To accurately determine the detected oil mist concentration, the photoelectric sensor is divided into a light source emitter and a light source receiver. The light source emitter is used to emit light signals, and the light source receiver is used to receive light signals. Step S2013: determining the detected oil mist concentration corresponding to the current data includes:

[0041] A first mapping relationship is constructed, which indicates the mapping relationship between the absorbance and the detected oil mist concentration and the light propagation path length;

[0042] Specifically, the first mapping relationship is represented as A(λ) = K(λ)CL, where A(λ) represents the absorbance, reflecting the degree of light intensity attenuation; K(λ) represents the light absorption coefficient, which depends on the properties of the transmission medium and the wavelength of light; C is the detected oil mist concentration, and L is the light propagation path length.

[0043] The first mapping relationship is the Beer-Lambert law, which is mainly based on the absorption characteristics of light. It describes the relationship between the intensity attenuation of light passing through an absorbing substance and the concentration of the substance.

[0044] A second mapping relationship is constructed, which indicates the relationship between the absorbance and the light intensity data of the emitted light signal and the light intensity data of the received light signal;

[0045] Specifically, the second mapping relationship is represented as: where A(λ) represents the absorbance, I light_0 represents the light intensity data of the emitted light signal, I light represents the light intensity data of the received light signal.

[0046] A third mapping relationship is constructed, which indicates the mapping relationship between the light intensity data and the current data;

[0047] Optionally, the third mapping relationship is a linear relationship, and the third mapping relationship is represented as: I light =aI current , I light_0 =aI current_0 , I light_0 represents the light intensity data of the emitted light signal, I light represents the light intensity data of the received light signal; I current_0 is the current data corresponding to the light intensity data of the emitted light signal, I current is the current data corresponding to the light intensity data of the received light signal, and a is a proportional constant.

[0048] A fourth mapping relationship is determined according to the first mapping relationship, the second mapping relationship, and the third mapping relationship, the fourth mapping relationship indicating a mapping relationship between the current data and the detected oil mist concentration, and the detected oil mist concentration corresponding to the current data is determined according to the fourth mapping relationship.

[0049] Specifically, the fourth mapping relationship is represented as:

[0050] Based on the absorption characteristics of light, especially the Beer-Lambert law, the first mapping relationship, the second mapping relationship, and the third mapping relationship are constructed, and then the fourth mapping relationship is determined according to the first mapping relationship, the second mapping relationship, and the third mapping relationship. The fourth mapping relationship reflects the relationship between the current data and the detected oil mist concentration, so the determination of the detected oil mist concentration is realized according to the processed current data.

[0051] In step S202, a second acquisition step is performed to acquire a preset oil mist concentration and a difference between the detected oil mist concentration and the preset oil mist concentration.

[0052] In step S203, an adjustment step is performed to adjust the oil mist collector motor speed according to the difference between the detected oil mist concentration and the preset oil mist concentration.

[0053] In some embodiments of the present application, step S203: an adjustment step is performed to adjust the oil mist collector motor speed according to the difference between the detected oil mist concentration and the preset oil mist concentration, including:

[0054] According to the difference between the detected oil mist concentration and the preset oil mist concentration, a working current required to control the oil mist collector is determined, and the oil mist collector motor speed is adjusted based on the working current. That is, the oil mist collector motor is driven by an electric signal, and there is a corresponding relationship between the size of the oil mist collector motor speed and the size of the electric signal driving it, specifically the working current of the electric signal machine, so that the working current can be adjusted to adjust the oil mist collector motor speed.

[0055] Step S204, loop step: sequentially repeat the above first acquisition step, the above second acquisition step and the above adjustment step at least once until the detected oil mist concentration detected again is equal to the preset oil mist concentration, or the difference between the detected oil mist concentration and the preset oil mist concentration is within the preset concentration range.

[0056] The method for adjusting the oil mist concentration of the machine tool provided by the application obtains the oil mist concentration in the machining environment of the machine tool to obtain a detected oil mist concentration, obtains a preset oil mist concentration and the difference between the detected oil mist concentration and the preset oil mist concentration, adjusts the motor speed of the oil mist collector according to the difference between the detected oil mist concentration and the preset oil mist concentration, and sequentially repeats the above first acquisition step, the above second acquisition step and the above adjustment step at least once until the detected oil mist concentration detected again is equal to the preset oil mist concentration, or the difference between the detected oil mist concentration and the preset oil mist concentration is within the preset concentration range. That is, based on the parameter of the detected oil mist concentration and by applying a feedback adjustment mechanism, the detected oil mist concentration is equal to the preset oil mist concentration, or the difference between the detected oil mist concentration and the preset oil mist concentration is within the preset concentration range. That is, the oil mist collection efficiency is dynamically adjusted according to the machining load or the actual operating condition.

[0057] In some embodiments of the application, the photoelectric sensor includes a light source emitter and a light source receiver, the light source emitter is used to emit a light signal, and the light source receiver is used to receive the light signal,

[0058] After the light intensity data is processed to obtain corresponding current data, the method further includes: determining whether the current data of the light source receiver is lower than a set minimum current threshold; if the current data of the light source receiver is lower than the set minimum current threshold, performing receiver alarm, and the causes of the receiver alarm include contamination of the surface of the light source receiver and / or failure of the light source receiver;

[0059] That is, if the current data of the light source receiver is lower than the set minimum current threshold, it indicates that the light source receiver cannot successfully receive the light signal emitted by the light source emitter, so a warning mechanism needs to be added to timely repair or replace the light source receiver.

[0060] and / or,

[0061] The method further comprises: if a peripheral control alarm occurs, suspending the acquisition of the detected oil mist concentration, wherein the peripheral control alarm indicates an alarm of a machine tool subsystem other than the oil mist concentration detection system. The machine tool comprises multiple subsystems, such as a driving subsystem, specifically including a motor and a transmission device, the motor providing power for the machine tool, such as a stepper motor or a servo motor, and the transmission device transmitting power from the motor to the machine tool, such as a gear, a belt, or a sprocket; a control subsystem, specifically including a computer numerical control (CNC) system and an operation panel, the CNC system controlling the movement and processing of the machine tool, and the operation panel being an interface for user interaction with the numerical control system for inputting programs and adjusting parameters; a feeding subsystem; and a workpiece clamping system, specifically including a clamp and a worktable, the clamp being a device for fixing a workpiece, such as a vice, a suction cup, or a chuck, and the worktable being a platform for carrying the workpiece and being movable or rotatable to adapt to different processing requirements. If an alarm of another subsystem occurs, it may affect the detection of the oil mist concentration and subsequent control, and therefore, if a peripheral control alarm occurs, the acquisition of the detected oil mist concentration also needs to be suspended for corresponding maintenance.

[0062] In some embodiments, the oil mist concentration in the machining environment of the machine tool is acquired to obtain a detected oil mist concentration, comprising:

[0063] The oil mist concentration detection period is set, wherein the oil mist concentration detection period can be set to 5 minutes, 10 minutes, 15 minutes, and the like.

[0064] Multiple oil mist concentrations are acquired within the oil mist concentration detection period, and the average value of the multiple oil mist concentrations is determined as the detected oil mist concentration. In this way, the system can timely capture the dynamic changes of the oil mist concentration, thereby providing a basis for subsequent current adjustment.

[0065] For the convenience of user viewing, the method further comprises: sending the detected oil mist concentration to a display end for real-time display of the detected oil mist concentration; and sending the working current of the motor to the display end for real-time display of the working current of the motor, wherein the working current of the motor corresponds to the motor speed. This visual data display form greatly improves the user's monitoring ability of the oil mist concentration and the operating state of the motor, so that any potential abnormal change can be timely detected and responded.

[0066] The method embodiments of the present application and the subsequent system embodiments and device embodiments have the following advantages:

[0067] 1. Improve oil mist collection efficiency: By monitoring the oil mist concentration in real time during the processing and dynamically adjusting the air volume of the oil mist collector and the motor speed according to the concentration, the oil mist collection effect can be optimized under different processing loads and operating conditions, and the oil mist removal efficiency can be significantly improved.

[0068] 2. Reduce energy consumption: The adaptive adjustment system can adjust the air volume and motor speed according to actual needs, thereby avoiding unnecessary energy waste and improving energy efficiency.

[0069] 3. Reduced Environmental Pollution: A highly efficient oil mist collection system effectively reduces oil mist pollution in the workshop air, providing operators with a healthier and safer working environment. Furthermore, by dynamically adjusting the motor speed, noise pollution caused by excessive airflow and speed in traditional systems can be avoided, further contributing to an improved workshop working environment.

[0070] 4. Enhanced System Adaptability: This solution is highly adaptable and can adjust the oil mist collection effect in real time according to different oil mist concentrations during the processing, adapting to different processing states and load conditions, thereby further improving the system's flexibility and reliability.

[0071] This application also provides a machine tool oil mist concentration adjustment system, such as... Figure 3 As shown, it includes: a control module, which is used to execute any of the above-described methods for adjusting the oil mist concentration of a machine tool. The control module executing the method for adjusting the oil mist concentration of a machine tool obtains a detected oil mist concentration by acquiring the oil mist concentration in the machine tool processing environment; acquires a preset oil mist concentration and the difference between the detected oil mist concentration and the preset oil mist concentration; adjusts the speed of the oil mist collector motor based on the difference between the detected oil mist concentration and the preset oil mist concentration; and repeats the first acquisition step, the second acquisition step, and the adjustment step at least once until the detected oil mist concentration is equal to the preset oil mist concentration, or the difference between the detected oil mist concentration and the preset oil mist concentration is within a preset concentration range. That is, based on the parameter of the detected oil mist concentration and by applying a feedback adjustment mechanism, the system achieves the condition that the detected oil mist concentration equals the preset oil mist concentration, or the difference between the detected oil mist concentration and the preset oil mist concentration is within a preset concentration range. This enables dynamic adjustment of the oil mist collection efficiency according to the processing load or actual operating conditions.

[0072] Furthermore, such as Figure 3 As shown, the above-mentioned machine tool oil mist concentration adjustment system also includes:

[0073] A photoelectric sensor installed in a machine tool processing environment includes a light source transmitter and a light source receiver. The light source transmitter is used to emit light signals, and the light source receiver is used to receive light signals.

[0074] The conversion module communicates with the aforementioned photoelectric sensor and is used to convert the aforementioned emitted light signal and the aforementioned received light signal into current data.

[0075] The communication module communicates with both the aforementioned conversion module and the aforementioned control module.

[0076] SeeFigure 4 C0 refers to the preset oil mist concentration, C av C0 refers to the preset oil mist concentration, C av The result obtained after operation, I motor I refers to the working current of the oil mist collector motor speed control, I current I refers to the mapping current of the light intensity received in the detection module.

[0077] Referring to Figure 3 and Figure 4 , the adaptive strategy-based machine tool oil mist concentration adjustment scheme aims to improve oil mist collection efficiency, reduce energy consumption and environmental pollution, and improve the adaptive ability of the system by accurately controlling the working state of the oil mist collector. The system mainly consists of the following modules: detection module, conversion module, control module and communication module. The overall control process can be summarized as follows: First, the detection module collects the oil mist concentration information in the machine tool environment through the photoelectric sensor, and obtains real-time oil mist data. Then, the conversion module processes the collected photoelectric signal (equivalent to the light intensity data sensed by the photoelectric sensor) and converts it into current data related to the oil mist concentration, so as to obtain accurate detection of the oil mist concentration. Based on these concentration data, the control module automatically adjusts the working current of the oil mist collector motor according to the preset adaptive strategy, and then controls the speed of the motor to adapt to the collection requirements under different oil mist concentrations, so as to realize optimized oil mist collection effect and energy consumption control. Finally, the communication module uploads the oil mist concentration, current data and working state of the motor to the numerical control system in real time, providing accurate monitoring data for the operator and supporting remote monitoring and management. This process dynamically adjusts the working state of each link, so that the entire oil mist collection system can respond in real time according to the working environment of the machine tool, improving the flexibility and energy efficiency of the system, while effectively reducing the pollution of oil mist to the environment. The following is a detailed introduction to each module:

[0078] 1、Detection module

[0079] The detection module is mainly composed of a light source emitter and a light receiver. Through precise optical design and structural layout, they achieve real-time monitoring and adjustment of oil mist concentration. The light source emitter is responsible for emitting light of a fixed wavelength through the machine tool working area, while the light source receiver receives the light signal scattered or reflected by the oil mist particles and converts it into an electrical signal for processing. In addition, to improve sensitivity and response speed, the light source emitter can be equipped with beam modulation technology such as pulsed light or frequency-modulated light, thereby enhancing the rapid response capability to changes in oil mist concentration. In terms of light source receivers, high-sensitivity photomultiplier tubes are usually used. This component can convert weak light signals into current signals. The high gain and sensitivity of the photomultiplier tube enable it to effectively capture weak scattered light under low light intensity conditions, making it suitable for oil mist concentration monitoring in industrial environments. The gain of the photomultiplier tube can be adjusted to amplify the received signal as needed, while its spectral response range must match the wavelength of the light source emitter to ensure efficient photoelectric conversion and accurate signal processing. In addition, the noise suppression capability of the photomultiplier tube when processing low light signals is also crucial to its efficient operation.

[0080] The light source emitter and receiver need to be installed symmetrically horizontally on both sides of the machine tool to ensure that the light uniformly penetrates the oil mist area and the receiver can fully capture the scattered light. In addition, the installation position should be selected below the main shaft or above the workbench of the machine tool, as these positions have higher oil mist concentration, which can ensure that the light effectively passes through the oil mist area and is accurately detected by the receiver.

[0081] 2. Conversion module

[0082] The core task of the conversion module is to establish an accurate mapping relationship between the detected oil mist concentration and the current signal, so as to reflect the fluctuation of oil mist concentration in real time through the change of current. The theoretical basis of this process mainly relies on the absorption characteristics of light, especially the Beer-Lambert law, which describes the relationship between the intensity attenuation of light passing through an absorbing substance and the concentration of the substance. Specifically, the Beer-Lambert law formula is:

[0083] A(λ) = K(λ)CL (1)

[0084] Where A(λ) represents the absorbance, reflecting the degree of light intensity attenuation; K(λ) represents the absorption coefficient, which depends on the properties of the transmission medium and the wavelength of the light; C is the oil mist concentration, and L is the propagation path length of the light.

[0085] According to the Beer-Lambert law, the absorption of light leads to the attenuation of light intensity, i.e. the absorbance is inversely proportional to the received light intensity, so the relationship between the received light intensity I light and the initial light intensity I light_0 is

[0086] I light = I light_0 e -A(λ) (2)

[0087] Further by taking logarithm, the relationship between absorbance and received light intensity can be derived as

[0088]

[0089] From (1) (3), the relationship between oil mist concentration and received light intensity is

[0090]

[0091] However, in practical applications, the received light signal needs to be converted into a current signal through a conversion module. To achieve this conversion, it is assumed that there is a linear relationship between the light intensity I light and the current signal I current , and there is a proportional constant a, so that

[0092] I light = aI current , I light_0 = aI current_0 (4) ;

[0093] In summary, the mapping relationship between oil mist concentration and current is:

[0094]

[0095] The conversion module reads the current signal output by the sensor and converts it into oil mist concentration according to the known mapping formula. Specifically, after the machine tool starts working, the current received is read in, and the corresponding oil mist concentration is calculated using formula (5). After the data calculation is completed, the system needs to compare the set threshold value to determine whether to trigger the alarm mechanism. The alarm can be divided into receiver alarm and peripheral control alarm, corresponding to different fault reasons and processing measures.

[0096] Receiver alarm is usually triggered when the received current signal is below the set minimum threshold, which may be caused by receiver surface contamination, oil mist sensor failure or external environmental changes. At this time, the system will first check whether the sensor's receiving window is covered by oil mist or dust and suggest cleaning; if cleaning is ineffective, the device needs to be replaced. Peripheral control alarm is usually caused by sensor failure, communication problems or unstable power supply, which will be issued by the numerical control system (CNC) to prompt the operator to check the communication line, power supply and device status, and perform maintenance or replacement if necessary.

[0097] In summary, the mapping relationship between oil mist concentration and current signal can effectively reflect the change law of light intensity, and the fluctuation of oil mist concentration can be monitored in real time through the current signal. The conversion process not only depends on the absorption characteristics of light, but also needs to consider the proportional relationship between light signal and current, thereby providing accurate and real-time concentration data for the system.

[0098] 3. Control module

[0099] The control module can automatically adjust the working current of the oil mist collector motor by obtaining the oil mist concentration data provided by the detection module and the conversion module in real time, so as to ensure that the oil mist concentration is maintained within the preset safe range, thereby optimizing the working efficiency of the system. The specific operation steps are described as follows:

[0100] Firstly, when the machine tool starts to run, the control module reads the initial working current of the oil mist collector motor and takes it as the reference value. In addition, the system also sets a fixed oil mist concentration threshold and a detection period, so as to monitor the oil mist concentration in real time within the specified time. In each detection period, the detection module collects the oil mist concentration data under the current working environment and calculates the average value of the oil mist concentration in this period. In this way, the system can timely capture the dynamic change of the oil mist concentration, thereby providing a basis for subsequent current adjustment.

[0101] After that, the system compares the calculated average value of the oil mist concentration with the pre-set concentration threshold. If the average value of the oil mist concentration is greater than the set threshold, it indicates that the oil mist concentration in the current air is high, and the system will automatically increase the working current of the oil mist collector motor. In this way, the adsorption capacity of the motor can be enhanced, thereby improving the oil mist collection efficiency and ensuring that the oil mist concentration quickly decreases to the safe range. If the average value of the oil mist concentration is exactly equal to the set concentration threshold, it means that the oil mist concentration is at the expected normal level, and at this time the control module will maintain the current working current of the oil mist collector motor to maintain a stable collection state. On the contrary, when the average value of the oil mist concentration is less than the set concentration threshold, it indicates that the oil mist concentration in the air is low, and at this time the system will reduce the working current of the motor to reduce its energy consumption, thereby avoiding unnecessary energy waste and helping to prolong the service life of the equipment.

[0102] After each adjustment of the working current, the system records the new current value and further processes and calculates these data through the PLC (Programmable Logic Controller) to evaluate whether the adjustment process needs to be executed again. Through this closed-loop feedback mechanism, the system can automatically adjust the working state of the oil mist collector according to the real-time data, thereby realizing adaptive adjustment in different working environments.

[0103] The biggest advantage of this adaptive control strategy is its high intelligence and automation. The system can automatically adjust the current based on real-time oil mist concentration data without human intervention, keeping the oil mist concentration within a safe range, thereby improving the overall system automation level and stability. In addition, by dynamically adjusting the motor's working current, it not only effectively avoids potential risks caused by excessive or insufficient oil mist concentration, but also significantly improves energy utilization efficiency, reduces power waste, and prolongs the service life of the equipment, thereby reducing maintenance costs. Overall, the entire process demonstrates the system's strong adaptability and efficiency, ensuring stable operation of the equipment while improving the intelligence level of energy management.

[0104] 4. Communication module

[0105] The communication module enables data transmission and information interaction between the detection module, conversion module, control module, and the numerical control system. Specifically, the oil mist concentration data collected by the detection module and conversion module in real time, as well as the working current data of the oil mist collector motor output by the control module, are timely uploaded to the numerical control system through the communication module. The realization of this data flow not only ensures efficient collaboration between the system's various modules, but also provides a solid foundation for subsequent data processing and system optimization.

[0106] By uploading these key data in real time to the numerical control system, the communication module can achieve centralized management and visual display of data. The numerical control system presents the changes in oil mist concentration and motor current to the operator in the form of charts or real-time curves through a graphical interface or dashboard. This visual data display greatly improves the user's monitoring ability of oil mist concentration and motor operating status, enabling any potential abnormal changes to be detected and responded to in a timely manner. For example, if the oil mist concentration exceeds the set safety threshold or the motor working current abnormally increases, the numerical control system can immediately reflect it, providing immediate feedback to the operator.

[0107] In addition, the communication module also plays a key role in the system's adaptive adjustment and fault warning. By uploading real-time data, the numerical control system can analyze and judge the data and start the alarm mechanism when necessary. When detecting that the oil mist concentration exceeds the set range or the motor working current is abnormal, the system will alert the operator through an alarm signal to handle it, avoiding damage or safety accidents caused by excessive oil mist concentration or abnormal current. This alarm mechanism is not limited to simple numerical value exceeding, but can also predict and warn potential risks in advance according to the preset adaptive process, combined with historical data and changes in the current environment.

[0108] Through the integrated information transmission and data monitoring, the role of the communication module is not limited to simple data transmission. Instead, it is actually a bridge and link between the oil mist concentration monitoring system and the numerical control system, ensuring real-time data feedback, triggering of early warning functions, and intelligent adjustment of the system. While improving system efficiency, it also enhances system safety and reliability, providing strong support for stable operation and maintenance of equipment.
