Description

Technical Field

[0001] The present application relates to the technical field of plasma surface treatment machines, and in particular to a high-efficiency control method and device for plasma excitation of a plasma surface treatment machine. Background Art

[0002] With the development of society and technology, new materials, fine materials and fragile materials continue to appear in various industries, playing their unique functions. For these materials, surface treatment is very important.

[0003] At present, metal films, battery separators, plastic films, aluminum-plastic composite films, silicone rubber, plastics and other products can be made cleaner after being surface treated by plasma surface processors, thus improving the final quality of the products and expanding their sales markets.

[0004] However, the comprehensive energy efficiency utilization rate of the plasma surface treatment machine has not been maximized, resulting in energy waste and affecting the surface treatment quality.

[0005] Furthermore, when plasma surface treatment machines are used on product surfaces, the treatment results vary due to varying product types and varying production line speeds. Currently, ensuring uniform treatment results relies solely on human experience, a method that wastes manpower and reduces production efficiency. Summary of the Invention

[0006] To solve the above problems, embodiments of the present application provide a method and apparatus for efficiently controlling plasma excitation of a plasma surface treatment machine.

[0007] In one aspect, the present application provides a method for high-efficiency control of plasma excitation in a plasma surface treatment machine, the method comprising:

[0008] Obtain the feeding information from the control terminal. Match the corresponding cleaning force according to the feeding information. The cleaning force is used to adjust the output power of the plasma excitation unit. Based on the cleaning force and the material flow rate, determine whether the output power of the plasma excitation unit corresponding to the material flow rate at the next moment meets the preset conditions. The preset condition is that the pending power determined based on the cleaning force matches the output power. If it is determined that the output power of the plasma excitation unit corresponding to the material flow rate at the next moment does not meet the preset conditions, the pending power is used as the output power to clean the surface of the material until the cleaning force corresponding to the feeding information is updated.

[0009] In one implementation of the present application, the operating speed of a plasma surface treatment machine is obtained and used as the material flow speed. Based on the cleaning power, material flow speed, material processing width, and material processing time, the undetermined power of the plasma excitation unit during the material processing time is determined. The output power of the plasma excitation unit at each moment during the material processing time is obtained. Each undetermined power is matched with each output power to determine whether the output power of the plasma excitation unit corresponding to the material flow speed at the next moment meets a preset condition.

[0010] In one implementation of the present application, several historical clean records of a plasma surface treatment machine are obtained from a preset database. The historical clean records include at least: the type of processed material, the width of processed material, the material cleanliness value, and the operating parameters. The material cleanliness value is used to characterize the cleanliness of the material. Each historical clean record whose material cleanliness value is greater than a preset threshold is determined to be a selected clean record. The pending clean force corresponding to each selected clean record is determined by a preset formula. The preset formula represents the relationship between the clean force and the output power, the material processing time, the material passage speed, and the material processing width. According to the type of processed material and the width of processed material in the selected clean record, a comparison table of each pending clean force and the feed information is generated to match the clean force in the comparison table according to the feed information.

[0011] In one implementation of the present application, a power weight for each plasma excitation unit is determined based on operational information of the operable plasma excitation units of a plasma surface treatment machine. Based on the output power and the power weight, an adaptive power for each plasma excitation unit is determined, so that the surface of the material is cleaned according to the adaptive power. The sum of the power values ​​of the adaptive powers equals the output power.

[0012] In one implementation of the present application, the operating time period of each operable plasma excitation unit is determined, and the operating time periods are combined to form the material processing time period. Each operable plasma excitation unit within the same operating time period is designated as a synchronously operating excitation terminal. A power adjustment range is obtained for each synchronously operating excitation terminal. The power adjustment range is determined based on the historical operating records of the excitation terminal. Based on each power adjustment range, a power weight is determined for each synchronously operating excitation terminal.

[0013] In one implementation of the present application, the interval values ​​of each power adjustment interval are normalized to obtain a normalized power interval, and the power weight of each synchronous operation excitation terminal is determined based on the normalized power interval.

[0014] In one implementation of the present application, an initial operating power ratio of each operable plasma ignition unit is determined based on the number of operable plasma ignition units in operation. The initial operating power ratio is processed using a least squares method based on historical operation records of each operable plasma ignition unit to obtain an operating power ratio, which is then used as a power weight.

[0015] In one implementation of the present application, when it is determined that the output power of the plasma excitation unit corresponding to the material passage speed at the next moment meets the preset conditions, an operation signal is sent to the plasma surface treatment machine to clean the surface of the material until the output power of the plasma excitation unit corresponding to the material passage speed at the next moment does not meet the preset conditions or the cleaning force corresponding to the feed information is updated.

[0016] In one implementation of the present application, cleanliness feedback information is generated and sent to a corresponding user terminal. Based on the user's operation on the user terminal, a material cleanliness value is determined. The cleanliness power is updated according to the material cleanliness value.

[0017] On the other hand, an embodiment of the present application further provides a plasma excitation high-efficiency control device for a plasma surface treatment machine, the device comprising:

[0018] At least one processor; and a memory communicatively connected to the at least one processor. The memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to:

[0019] Obtain feed information from the control terminal. Based on this feed information, match the corresponding cleaning force. The cleaning force is used to adjust the output power of the plasma excitation unit. Based on the cleaning force and material flow rate, determine whether the output power of the plasma excitation unit corresponding to the material flow rate at the next moment meets the preset conditions. The preset condition is that the pending power determined based on the cleaning force matches the output power. If not, the pending power is used as the output power to clean the material surface until the cleaning force corresponding to the feed information is updated.

[0020] Through the above scheme, the power of material surface treatment can be guaranteed to be stable at different material passage speeds, and the clean force fixed value treatment product can be satisfied. It can achieve maximum efficiency output with clean force as the goal, improve the energy efficiency utilization rate of the plasma excitation unit, thereby ensuring the overall high-efficiency output of the plasma surface treatment machine and improving the treatment effect on the product. Ensure the quality consistency during the product processing process. The output power can also be adjusted to ensure that the product reaches the expected quality. This application uses the above scheme to collect material information, output power, adjust the output of the plasma excitation unit, and no longer need to rely on human experience to process products, which can ensure the uniformity of product processing effects. This solution saves manpower and has high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Plasma surface treatment machines consist of one or more plasma excitation units, which generate plasma to clean the surfaces of materials (such as metal films, battery separators, plastic films, aluminum-plastic composite films, silicone rubber, and plastics). Current plasma surface treatment machines, when moving at different speeds under the plasma excitation units for different material types, can result in incomplete surface cleaning, inconsistent surface cleaning results after cleaning, and uncertainty about whether the cleaned products are from the same batch. In some cases, the cleaned products may not meet expectations.

[0026] When the above problems occur, if we only rely on human experience to adjust the plasma surface treatment machine, directly or reprocess the unqualified products, we will be overly dependent on human resources and the efficiency of material processing will be low.

[0027] Based on this, the embodiments of the present application provide a high-efficiency control method and equipment for plasma excitation of a plasma surface treatment machine, which is used to uniformly process materials, improve product quality and material processing efficiency.

[0028] The following describes in detail various embodiments of the present application with reference to the accompanying drawings.

[0029] The embodiment of the present application provides a high-efficiency control method for plasma excitation of a plasma surface treatment machine, such as Figure 1 As shown, the method may include steps S101-S104:

[0030] S101, the server obtains feeding information from the control terminal.

[0031] In the embodiments of the present application, the control terminal can be a handheld terminal such as a mobile phone, a personal digital assistant (PDA), a laptop computer, a server, or an external device with communication capabilities installed on the plasma surface treatment machine. The present application does not specifically limit the type of control terminal.

[0032] In the embodiments of the present application, feed information refers to information about the material to be treated by the plasma surface treatment machine, such as the material type and width. The materials herein include at least glass, aluminum foil, and film. The types of materials are not specifically limited. Any product whose surface can be treated by the plasma surface treatment machine to achieve a cleaning purpose can be considered a material.

[0033] If the control terminal has image recognition and scanning recognition functions, it can automatically obtain the feed information; or the user can manually input the feed information through the control terminal, and then send the feed information to the server. This application does not specifically limit how the control terminal obtains the feed information.

[0034] It should be noted that the server as the executor of the plasma excitation high-efficiency control method of the plasma surface treatment machine is only an example. The executor is not limited to the server, and this application does not make any specific restrictions on this.

[0035] S102, the server matches the corresponding cleaning force according to the feed information.

[0036] Among them, the clean force is used to adjust the output power of the plasma excitation unit.

[0037] In the embodiments of this application, different feed information corresponds to different cleaning forces. The cleaning force is the constant pressure discharge power output per unit time and per unit area of ​​the material surface when the processed material continuously passes through the constant power discharge area in one direction at a constant speed. The cleaning force formula is as follows:

[0038]

[0039] Among them, L is the cleaning power, and the unit of cleaning power is: kilowatt*second / square meter, W Z is the total power of the plasma surface treatment machine, t is the material treatment time, S is the material treatment area of ​​the plasma surface treatment machine, W f is the output power of each plasma excitation unit of the plasma surface treatment machine, n is the number of plasma excitation units, v is the material passing speed, and F is the processing width of the plasma surface treatment machine.

[0040] In the embodiment of the present application, the server matches the corresponding cleaning force according to the feed information, specifically including:

[0041] The server obtains a number of historical cleaning records of the plasma surface treatment machine from a preset database.

[0042] The historical cleanliness records include at least: the type of material processed, the width of the material processed, the material cleanliness value, and the operating parameters. The material cleanliness value is used to indicate the cleanliness level of the material.

[0043] In an embodiment of the present application, the preset database stores historical clean records of the plasma surface treatment machine when processing materials. For example, the plasma surface treatment machine processes a batch of materials with a width of A and a length of B, and records the material type of the batch of materials, the width of the processed materials, the material cleanliness value fed back after processing, and the operating parameters of the plasma surface treatment machine during operation (speed, power, etc.).

[0044] The server determines each historical clean record whose material cleanliness value is greater than a preset threshold as a selected clean record.

[0045] In this embodiment of the present application, based on the material cleanliness value, historical cleanliness records with material cleanliness values ​​greater than a preset threshold are selected. Subsequent materials can be processed using the selected cleanliness record. When processing materials thereafter, the required cleaning force can be determined based on the material type and width, enabling the plasma surface treatment machine to achieve the desired cleaning effect as determined by the selected cleanliness record when processing various materials.

[0046] The server determines the pending cleaning force corresponding to each selected cleaning record through a preset formula.

[0047] Among them, the preset formula represents the relationship between cleaning power and output power, material processing time, material passage speed and material processing width.

[0048] In an embodiment of the present application, the preset formula refers to the above-mentioned cleaning power formula. After inputting the output power (the total power of the plasma surface treatment machine or the output power of each plasma excitation unit of the plasma surface treatment machine), the material processing time, the material passage speed and the material processing width into the cleaning power formula, the corresponding pending cleaning power of each selected cleaning record can be obtained.

[0049] The server generates a comparison table of each pending cleaning force and feed information according to the type of processed material and the width of processed material in the selected clean record, so as to match the cleaning force in the comparison table according to the feed information.

[0050] In the embodiment of the present application, the feed information (processing material type, processing material width) can correspond to different or the same pending cleaning force. The server can generate a comparison table of the corresponding relationships and store it in a preset database. After obtaining the feed information from the control terminal, the server can query the comparison table to obtain the pending cleaning force corresponding to the feed information.

[0051] Through the above scheme, the cleaning force corresponding to the feed information is matched, and the materials can be uniformly processed, that is, the power output by the plasma surface treatment machine when processing the materials can be applied to the surface of the materials based on the cleaning force, so that the processed materials can achieve the expected quality and improve the processing effect of different products or the same products.

[0052] S103: The server determines whether the output power of the plasma excitation unit corresponding to the material passing speed at the next moment meets a preset condition based on the cleaning power and the material passing speed.

[0053] Among them, the preset condition is that the undetermined power determined based on the cleaning power matches the output power.

[0054] The plasma excitation unit includes a plasma excitation discharge electrode and a power supply in a plasma surface treatment machine, and is used to treat the surface of the material.

[0055] In the embodiment of the present application, the material flow speed is the speed at which the plasma surface treatment machine transports the material. Based on the cleaning power and the material flow speed, determining whether the output power of the plasma excitation unit corresponding to the material flow speed at the next moment meets the preset conditions specifically includes:

[0056] The server obtains the operating speed of the plasma surface treatment machine and uses the operating speed as the material passing speed.

[0057] The server determines the pending power of the plasma excitation unit within the material processing time based on the cleaning force, material passing speed, material processing width and material processing time.

[0058] In this embodiment of the present application, the server inputs the matching cleaning force, material flow speed, material processing width, and material processing time into the above cleaning force formula to obtain the undetermined power of the plasma excitation unit during the material processing time. The undetermined power here can be the total power of the plasma excitation unit of the plasma surface treatment machine.

[0059] The server obtains the corresponding output power of the plasma excitation unit at each moment during the material processing time.

[0060] In the embodiment of the present application, the server can determine the current operating current of the plasma excitation unit, and then obtain the output power of the plasma excitation unit according to the operating voltage of the plasma surface treatment machine.

[0061] The server matches each pending power with each output power to determine whether the output power of the plasma excitation unit corresponding to the material passing speed at the next moment meets the preset conditions.

[0062] In an embodiment of the present application, the server may compare and match the obtained pending power with the output power. For example, if the pending power is a kWh and the output power is b kWh, the server determines whether the output power b kWh is within the neighborhood of the pending power a kWh [ax, a+x], where x is a set value. The specific value can be set during actual use.

[0063] S104, when the server determines that the output power of the plasma excitation unit corresponding to the material passing speed at the next moment does not meet the preset conditions, the server uses the undetermined power as the output power to clean the surface of the material until the cleaning power corresponding to the feeding information is updated.

[0064] In this embodiment of the present application, after the feed information is matched to the cleaning force, the plasma surface treatment machine needs to be adjusted in real time so that the plasma surface treatment machine can adjust the material surface through a uniform cleaning force. The server uses the undetermined power as the output power to clean the material surface, specifically including:

[0065] The server determines the power weight of each plasma excitation unit according to the operation information of the operable plasma excitation units of the plasma surface treatment machine.

[0066] The plasma surface treatment machine can be equipped with multiple plasma excitation units, which can be operated at different time periods to provide different levels of cleaning power to the material, or to provide the same cleaning power to different materials, or to provide uniform cleaning power to the material at different material transport speeds. The server determines the power weight of each plasma excitation unit based on the operating information of the operable plasma excitation units of the plasma surface treatment machine, specifically including:

[0067] First, the server determines the operating time period of each operable plasma excitation unit, and the operating time periods are combined to form the material processing time period.

[0068] In the embodiment of the present application, while determining the material information, the operating time period of the plasma excitation unit can be obtained. The operable plasma excitation unit is a plasma excitation unit that works during the material processing process. It can also refer to a plasma excitation unit that is installed on a plasma surface treatment machine and can be operated. For material processing, because the material transportation speed of the plasma surface treatment machine may change during actual use, the plasma excitation unit can be operated in different time periods to ensure that materials at different speeds are processed with uniform cleaning power.

[0069] Next, the server uses each operable plasma excitation unit in the same operation period as a synchronous operation excitation terminal.

[0070] The operable plasma excitation units within the same operating period refer to the operating periods T1, T2, and T3 that constitute the material processing time T. Within the operating period T1, there are operable plasma excitation units N1, N2, and N3, so N1, N2, and N3 are synchronously operating excitation terminals.

[0071] Subsequently, the server obtains the power adjustment interval of each synchronous operation excitation terminal.

[0072] The power adjustment range is obtained based on the historical operation records of the excitation terminal.

[0073] In the embodiment of the present application, the power adjustment range is the range within which each plasma excitation unit can output power, for example, the range for excitation terminal N1 is [w1, w2], and the range for excitation terminal N2 is [w1+1, w2+1]. This power adjustment range is obtained based on the output power recorded in the historical operation records of the excitation terminal during actual use.

[0074] Then, the server determines the power weight of each synchronous operation excitation terminal according to each power adjustment interval.

[0075] In the embodiment of the present application, the server determines the power weight of each synchronous operation excitation terminal according to each power adjustment interval, specifically including:

[0076] In the first step, the server normalizes the interval values ​​of each power adjustment interval to obtain a normalized power interval.

[0077] The normalization operation can be specifically as follows. For example, the power adjustment interval has a range of values: 2, 3, 4, 5. This range includes the maximum and minimum values. After normalization, the range of values ​​is: 0.14, 0.21, 0.29, 0.36. The normalized power interval is [0.14, 0.36].

[0078] In the second step, the server determines the power weight of each synchronous operation excitation terminal based on the normalized power range.

[0079] After the server obtains the normalized power range, it can calculate the power weight of each synchronous operation excitation terminal based on the normalized power range. For example, if the normalized power range of the first synchronous operation excitation terminal is [0.2, 0.3] and the normalized power range of the second synchronous operation excitation terminal is [0.22, 0.4], then the power adjustment range of the first synchronous operation excitation terminal is 0.3-0.2=0.1, and the power adjustment range of the second synchronous operation excitation terminal can reach 0.4-0.22=0.18. The power weight can then be calculated according to the ratio of 1:1.8, for example, the power weight of the first synchronous operation excitation terminal is 0.35, and the power weight of the second synchronous operation excitation terminal is 0.65.

[0080] In another embodiment of the present application, the server determines the power weight of each plasma excitation unit according to the operation information of the operable plasma excitation units of the plasma surface treatment machine, which may further specifically include:

[0081] The server determines the initial operating power ratio of each operable plasma excitation unit according to the operating quantity of each operable plasma excitation unit.

[0082] In the embodiment of the present application, the number of plasma excitation units that can be operated is, for example, three plasma excitation units. The initial operating power ratio of each plasma excitation unit is obtained based on the number of plasma excitation units. For example, the initial operating power ratio of the three plasma excitation units is one-third.

[0083] The server processes the initial operating power ratio by the least square method according to the historical operating records of each operable plasma excitation unit to obtain the operating power ratio, and uses the operating power ratio as the power weight.

[0084] The server can retrieve the historical operation records of each operational plasma excitation unit. An operational plasma excitation unit refers to the plasma excitation unit that is currently operating during material processing. For example, if a plasma surface treatment machine has five plasma excitation units and only three of them, j, k, and l, are required to process material m, the server will retrieve the historical operation records for these units.

[0085] Based on the historical operation records of each plasma excitation unit, the power adjustment ratio of each unit during material processing is determined. The server can also generate a power adjustment ratio curve, which can be used to determine the power allocation required for each of the multiple operational plasma excitation units when running simultaneously. Specifically, the least squares method can be used to fit the power adjustment ratio data or curve to determine the power allocation required for each of the multiple operational plasma excitation units.

[0086] For example, when the power of plasma excitation unit j is x1, the power of k needs to be x2, and the power of l needs to be x3, but x1+x2+x3 does not meet the output power requirements; the server then adjusts their respective power ratios through the least squares method. When the power of plasma excitation unit j is x2, the power of k is x4, and the power of l is x1, the output power requirements can be met. Then the operating power ratio of each operable plasma excitation unit can be obtained: x2:x4:x1, and it can be used as the power weight.

[0087] Finally, the server determines the adaptive power of each plasma excitation unit according to the output power and power weight, so as to clean the surface of the material according to the adaptive power.

[0088] The sum of the powers of the adapted powers is equal to the output power.

[0089] That is, after the server multiplies the output power by the power weight of each synchronous operation excitation terminal, it can obtain the power required to be output by each synchronous operation excitation terminal, that is, the adaptive power of the plasma excitation unit.

[0090] In one embodiment of the present application, in the past, achieving consistent quality of treated materials using the aforementioned solution required individual settings for the output power of each plasma excitation unit, a cumbersome process. However, the present application utilizes the aforementioned solution, which allows for the output power settings of each plasma excitation unit to be achieved simply by setting a fixed cleaning power parameter. This simplifies operation and enhances user experience for the operator.

[0091] For example, there may be multiple plasma excitation units, and material X may require different output powers from each plasma excitation unit. Therefore, the operator may need to adjust the output power of each plasma excitation unit one by one to process the material. However, with the technical solution of this application, the operator only needs to adjust the cleaning power to meet the actual output power requirements of multiple plasma excitation units, eliminating the need for individual adjustments, making the operation more convenient.

[0092] Through the above scheme, when the plasma surface treatment machine has multiple plasma excitation units (plasma excitation units), the output of each unit can be collected, calculated, and adjusted as a whole, so as to achieve maximum efficiency output with cleaning power as the goal, and then achieve overall high-efficiency output, thereby improving the plasma surface treatment machine's treatment effect on products.

[0093] In addition, the plasma surface treatment machine can also have one or more plasma excitation units, and the excitation units can meet the requirements of different operating speeds, change the output power, and meet the cleaning force constant, so as to achieve the goal of ensuring that the total output of the plasma surface treatment machine acts on the treated object when the speed changes, and then ensure the quality consistency of the product throughout the entire treatment process.

[0094] When a plasma surface treatment machine has two or more plasma excitation units, it can collect, calculate, and adjust the output power of each plasma excitation unit to ensure that the overall output reaches the set cleaning power value, thereby ensuring the expected (preset) quality of the product.

[0095] In one embodiment of the present application, when it is determined that the output power of the plasma excitation unit corresponding to the material passage speed at the next moment meets the preset conditions, the server sends an operating signal to the plasma surface treatment machine to clean the surface of the material until the output power of the plasma excitation unit corresponding to the material passage speed at the next moment does not meet the preset conditions or the cleaning force corresponding to the feed information is updated.

[0096] In addition, in another embodiment of the present application, after the server uses the to-be-determined power as the output power to clean the surface of the material, the further embodiment further includes:

[0097] First, the server generates and sends clean feedback information to the corresponding user terminal.

[0098] The user terminal can be a terminal (mobile phone, computer, etc.) bound to the plasma surface treatment machine, or a terminal with a terminal dialing number stored in the server, such as a mobile phone number. The clean feedback information can include images, text, etc.

[0099] Next, the server determines the material cleanliness value of the material based on the user's operation on the user terminal.

[0100] The user can operate the user terminal based on the cleanliness feedback information. For example, if the cleanliness feedback information is a processed material image, the user terminal can select a material cleanliness value. The material cleanliness value can be a grade score preset by the server, or it can be set in a score range and scored by the user. The score is used to represent the material cleanliness value.

[0101] Then, the server updates the cleanliness according to the material cleanliness value.

[0102] The update can determine whether the material's cleanliness value is greater than a preset threshold. For materials with a cleanliness value less than or equal to the preset threshold, the server can retroactively query the cleanliness power, material information, and operation records of the corresponding material. Based on the retroactive query results, the cleanliness power can be readjusted to reprocess unqualified materials (material cleanliness values ​​less than or equal to the preset value).

[0103] Through the above scheme, the plasma surface treatment machine can treat the surface of the material with a uniform or set cleaning power, and can ensure the consistency of material quality during material treatment at different material transportation speeds; the output power of each plasma excitation unit of the plasma surface treatment machine is also adapted to ensure the output power stability, which can ensure that the material treatment effect reaches the expected quality during material treatment. This application can maximize the efficiency output by collecting, calculating, and adjusting the output of the plasma surface treatment machine, so that the plasma surface treatment machine has high efficiency output and improves the product treatment effect of the same sharp device processor.

[0105] At least one processor; and a memory communicatively connected to the at least one processor. The memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to:

[0106] Obtain feed information from the control terminal. Based on this feed information, match the corresponding cleaning force. The cleaning force is used to adjust the output power of the plasma excitation unit. Based on the cleaning force and material flow rate, determine whether the output power of the plasma excitation unit corresponding to the material flow rate at the next moment meets the preset conditions. The preset condition is that the pending power determined based on the cleaning force matches the output power. If not, the pending power is used as the output power to clean the material surface until the cleaning force corresponding to the feed information is updated.
