Description

Technical Field

Background Art

[0002] In modern machine tool processing, in order to improve the surface quality and processing efficiency of the workpiece, coolant or lubricant is usually used to reduce friction and heat accumulation during the cutting process. Especially when performing high-speed and heavy-load cutting operations, the generation of oil mist is unavoidable. This oil mist not only pollutes the working environment and reduces air quality, but also may cause potential harm to the health of operators.

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

[0004] Most existing oil mist collectors use a motor to drive a fan to create air flow and draw the oil mist into the filter. The motor speed and air volume directly affect the oil mist collection efficiency. However, traditional systems usually use fixed air volume and motor speed, and cannot dynamically adjust the collection efficiency according to the processing load or actual operating conditions, which may lead to poor collection results and even oil mist overflow or accumulation. In addition, excessive air volume and motor speed will lead to energy waste and increased noise, while insufficient air volume will lead to incomplete oil mist collection, which will affect the air quality in the workshop.

[0033] Figure 2 FIG. 1 is a flow chart of a method for adjusting the oil mist concentration of a machine tool according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

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

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

[0036] Step S2011: Acquire light intensity data sensed by the above-mentioned photoelectric sensor;

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

[0038] Step S2013: Determine the above-mentioned detected oil mist concentration corresponding to the above-mentioned current data. A corresponding relationship is pre-established between the current data and the detected oil mist concentration;

[0039] The photoelectric sensor detects a light signal, which needs to be converted into an electrical signal, specifically current data, for the convenience of subsequent processing; then the oil mist concentration is determined based on the current data.

[0040] In order to accurately determine the detected oil mist concentration, the photoelectric sensor is divided into a light source transmitter and a light source receiver. The light source transmitter is used to transmit 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] Constructing a first mapping relationship, wherein the first mapping relationship indicates a mapping relationship between absorbance and the detected oil mist concentration and the light propagation path length;

[0042] Specifically, the first mapping relationship is expressed as: A(λ)=K(λ)CL, where A(λ) represents 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 light; C is the detected oil mist concentration, and L is the length of the light propagation path.

[0043] The first mapping relationship mentioned above is the Beer-Lambert law. The theoretical basis of the Beer-Lambert law mainly relies on the absorption characteristics of light. It describes the relationship between the attenuation of the intensity of light and the concentration of the substance when light passes through an absorbing substance.

[0044] Constructing a second mapping relationship, wherein the second mapping relationship indicates a 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 expressed as: Where A(λ) represents absorbance, I light_0 Represents the light intensity data of the emitted light signal, I light Indicative of light intensity data of a received light signal;

[0046] Constructing a third mapping relationship, wherein the third mapping relationship indicates a 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 expressed as: 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 the 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 indicates 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 expressed as:

[0050] As described above, 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. Therefore, the detected oil mist concentration is determined according to the current data obtained after processing.

[0051] Step S202, a second acquisition step: acquiring a preset oil mist concentration, and a difference between the detected oil mist concentration and the preset oil mist concentration;

[0052] Step S203, adjustment step: adjusting the speed of the oil mist collector motor 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: adjusting step: adjusting the speed of the oil mist collector motor according to the difference between the detected oil mist concentration and the preset oil mist concentration, comprises:

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

[0055] Step S204, a loop step: repeat the first acquisition step, the second acquisition step and the adjustment step at least once in sequence 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 the preset concentration range.

[0056] The method for adjusting the oil mist concentration of a machine tool of the present application obtains the detected oil mist concentration by acquiring the oil mist concentration in the machining environment of the machine tool; obtains the 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 according to the difference between the detected oil mist concentration and the preset oil mist concentration; repeats the first acquisition step, the second acquisition step and the adjustment step at least once in sequence until the detected oil mist concentration obtained by re-detection is equal to the preset oil mist concentration, or the difference with the preset oil mist concentration is within the preset concentration range. That is, based on the parameter of the detected oil mist concentration and applying a feedback adjustment mechanism, the detected oil mist concentration is equal to the preset oil mist concentration, or the difference with 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 actual operating conditions.

[0057] In some embodiments of the present application, the photoelectric sensor includes a light source transmitter and a light source receiver, wherein the light source transmitter is used to transmit a light signal, and the light source receiver is used to receive a light signal.

[0058] After processing the light intensity data 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, a receiver alarm is issued, and the reasons for the receiver alarm include surface contamination of the light source receiver and / or failure of the light source receiver;

[0059] That is to say, if the current data of the light source receiver is lower than the minimum current threshold set above, it means that the light source receiver cannot successfully receive the light signal emitted by the light source transmitter, so it is necessary to add an early warning mechanism to promptly inspect or replace the light source receiver.

[0060] and / or,

[0061] The above method also includes: if there is a peripheral control alarm, suspending the acquisition of the above detected oil mist concentration, wherein the above peripheral control alarm indicates that the machine tool subsystem other than the oil mist concentration detection system is alarmed. The machine tool includes multiple subsystems, for example, a drive subsystem, specifically including a motor and a transmission device, the motor provides power for the machine tool, such as a stepper motor, a servo motor, and the transmission device transmits the power of the motor to the machine tool, such as gears, belts, sprockets, etc.; a control subsystem, specifically including a computer numerical control (CNC) system and an operation panel, the computer numerical control (CNC) system controls the movement and processing process of the machine tool, and the operation panel is an interface for the user to interact with the CNC system, which is used to input programs and adjust parameters; a feed subsystem; a workpiece clamping system, specifically including a fixture and a workbench, the fixture is a device for fixing the workpiece, such as a vise, a suction cup, a chuck, etc., and the workbench is a platform for carrying the workpiece, which can be moved or rotated to adapt to different processing requirements; that is, if other subsystems alarm, it may affect the detection of the oil mist concentration and subsequent control, so if the peripheral control alarm is, it is also necessary to suspend the acquisition of the above detected oil mist concentration for corresponding maintenance.

[0062] In some embodiments, obtaining the oil mist concentration in the machine tool processing environment to obtain the detected oil mist concentration includes:

[0063] Set the oil mist concentration detection cycle, where the oil mist concentration detection cycle can be set to 5min, 10min, 15min, etc.;

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

[0065] To facilitate user viewing, the method further includes: sending the detected oil mist concentration to the display end to display the detected oil mist concentration in real time; sending the working current of the motor to the display end to display the working current of the motor in real time, 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 motor operating status, so that any potential abnormal changes can be detected and responded to in a timely manner.

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

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

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

[0069] 3. Reduce environmental pollution: The efficient oil mist collection system can effectively reduce the pollution of oil mist to the workshop air, thus providing operators with a healthier and safer working environment. Moreover, by dynamically adjusting the motor speed, the noise pollution caused by excessive air volume and speed in the traditional system can be avoided, which also helps to improve the workshop working environment.

[0070] 4. Improve system adaptability: This solution has strong adaptability and can adjust the oil mist collection effect in real time according to the different oil mist concentrations in the processing process, adapt to different processing states and load conditions, and further improve the flexibility and reliability of the system.

[0071] The present application also provides a machine tool oil mist concentration adjustment system, such as Figure 3 As shown, it includes: a control module, the control module is used to execute any one of the above methods for adjusting the oil mist concentration of a machine tool.

[0077] See also Figure 3 and Figure 4 The oil mist concentration adjustment scheme for machine tools based on adaptive strategy aims to improve the oil mist collection efficiency, reduce energy consumption, reduce environmental pollution, and enhance the adaptive ability of the system by accurately controlling the working state of the oil mist collector. The system is mainly composed of the following modules: detection module, conversion module, control module and communication module. Its 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 to obtain 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, thereby obtaining 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 achieve optimized oil mist collection effect and energy consumption control. Finally, the communication module uploads the oil mist concentration, current data and the working state of the motor to the CNC system in real time, providing operators with accurate monitoring data and supporting remote monitoring and management. This process dynamically adjusts the working status of each link, allowing the entire oil mist collection system to 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 transmitter and a light receiver, which realize real-time monitoring and adjustment of oil mist concentration through precise optical design and structural layout. The light source transmitter is responsible for emitting light of a fixed wavelength through the working area of ​​the machine tool, while the light source receiver receives the light signal after scattering or reflection by the oil mist particles and converts it into an electrical signal for processing. In addition, in order to improve sensitivity and response speed, the light source transmitter can also be equipped with beam modulation technology, such as a pulse light source or a frequency modulated light source, so as to enhance the ability to respond quickly to changes in oil mist concentration. In terms of the light source receiver, a highly sensitive photomultiplier tube is usually used, which 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, which is suitable for oil mist concentration monitoring in industrial environments. The gain of the photomultiplier tube is adjustable, and the received signal can be amplified according to actual needs. At the same time, its spectral response range must match the wavelength of the light source transmitter to ensure efficient photoelectric conversion and accurate signal processing. In addition, the noise suppression ability of the photomultiplier tube when processing low light signals is also the key to its efficient operation.

[0080] The light source transmitter and receiver need to be installed on both sides of the machine tool in a horizontally symmetrical manner to ensure that the light penetrates the oil mist area evenly and the receiver can fully capture the scattered light. In addition, the installation location should be selected below the spindle of the machine tool or above the workbench, because these locations have a 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 the oil mist concentration in real time through the current change. 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 attenuation of light intensity and the concentration of the substance when light passes through the absorbing substance. Specifically, the formula of the Beer-Lambert law is:

[0083] A(λ)=K(λ)CL(1)

[0084] A(λ) represents absorbance, which reflects 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 light; C is the oil mist concentration, and L is the length of the light propagation path.

[0085] According to the Beer-Lambert law, the absorption of light causes the attenuation of light intensity, that is, the absorbance is inversely proportional to the received light intensity, so the received light intensity I light With the initial light intensity I light_0 The relationship between

[0086] I light =I light_0 e -A(λ) (2)

[0087] By further taking the logarithm, the relationship between absorbance and received light intensity can be deduced 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 optical signal needs to be converted into a current signal through a conversion module. To achieve this conversion, assume that the light intensity I light With the current signal I current There is a linear relationship between them, and there is a proportionality constant a such 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, it reads the current value currently received and uses formula (5) to calculate the corresponding oil mist concentration. After the data calculation is completed, the system needs to compare the set threshold to determine whether to trigger the alarm mechanism. Alarms can be divided into receiver alarms and peripheral control alarms, which correspond to different fault causes and treatment measures.

[0096] Receiver alarms are usually triggered by the received current signal being lower than the set minimum threshold, which may be caused by contamination of the receiver surface, oil mist sensor failure, or changes in the external environment. At this time, the system will first check whether the sensor's receiving window is covered with oil mist or dust, and recommend cleaning; if cleaning is ineffective, the device needs to be replaced. Peripheral control alarms are usually caused by sensor failure, communication problems, or unstable power supply. Such alarms will be issued by the CNC system (CNC) to prompt the operator to check the communication line, power supply, and equipment status, and repair or replace them if necessary.

[0097] In summary, the mapping relationship between oil mist concentration and current signal can effectively reflect the changing law of light intensity, and monitor the fluctuation of oil mist concentration in real time through current signal. This conversion process not only depends on the absorption characteristics of light, but also needs to take into account the proportional relationship between light signal and current, so as to provide the system with accurate and real-time concentration data.

[0098] 3. Control module

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

[0100] First, when the machine tool starts running, the control module reads the initial working current of the oil mist collector motor and uses it as the baseline value. In addition, the system sets a fixed oil mist concentration threshold and detection cycle to monitor the oil mist concentration in real time within the specified time. In each detection cycle, the detection module collects the oil mist concentration data under the current working environment and calculates the average oil mist concentration in the cycle. In this way, the system can capture the dynamic changes of the oil mist concentration in time, thus providing a basis for subsequent current adjustments.

[0101] After that, the system will compare the calculated mean value of the oil mist concentration with the pre-set concentration threshold. If the mean value of the oil mist concentration is greater than the set threshold, it means that the current oil mist concentration in the air is high, and the system will automatically increase the operating current of the oil mist collector motor. This can enhance the adsorption capacity of the motor, thereby improving the oil mist collection efficiency and ensuring that the oil mist concentration is quickly reduced to a safe range. If the mean 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. At this time, the control module will maintain the current operating current of the oil mist collector motor to maintain a stable collection state. On the contrary, when the mean value of the oil mist concentration is less than the set concentration threshold, it means that the oil mist concentration in the air is low. At this time, the system will reduce the operating current of the motor and reduce its energy consumption, thereby avoiding unnecessary energy waste and helping to extend the service life of the equipment.

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

[0103] The biggest advantage of this adaptive control strategy is its high degree of intelligence and automation. The system can automatically adjust the current according to the real-time collected oil mist concentration data without manual intervention to keep the oil mist concentration within a safe range, thereby improving the automation level and stability of the overall system. In addition, by dynamically adjusting the working current of the motor, it can not only effectively avoid the potential risks caused by excessively high or low oil mist concentrations, but also significantly improve energy utilization efficiency, reduce electricity waste, and thus extend the service life of the equipment and reduce maintenance costs. In general, the whole process demonstrates the strong adaptability and efficiency of the system, which not only ensures the stable operation of the equipment, but also improves the intelligence level of energy management.

[0104] 4. Communication module

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

[0106] By uploading these key data to the CNC system in real time, the communication module can realize centralized management and visual display of data. The CNC system displays 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 form greatly improves the user's ability to monitor the oil mist concentration and motor operating status, so that any potential abnormal changes can be detected and responded to in a timely manner. For example, if the oil mist concentration exceeds the set safety threshold, or the motor operating current increases abnormally, the CNC system can immediately reflect it, thereby providing instant feedback to the operator.

[0107] In addition, the communication module also plays a key role in the adaptive adjustment and fault warning of the system. By uploading real-time data, the CNC system can analyze and judge the data and activate the alarm mechanism when necessary. When it is detected that the oil mist concentration exceeds the set range or the motor operating current is abnormal, the system will remind the operator to handle it through an alarm signal to avoid damage or safety accidents caused by excessive oil mist concentration or abnormal current. This alarm mechanism is not limited to simple numerical over-limit, but can also predict and warn of potential risks in advance based on the preset adaptive process, combined with historical data and changes in the current environment.

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