Description

Technical Field

[0001] This invention relates to the field of thin film processing and manufacturing technology, and more specifically, to an intelligent control method, system, electronic device, and computer storage medium for an adsorption roller used in thin film processing. Background Technology

[0002] Adsorption rollers are important components in thin film processing and manufacturing technology. They use the principle of adsorption to adsorb the film to be processed onto the roller, so that the film rotates with the roller, thereby realizing subsequent processing of the film, such as slitting and rewinding.

[0003] Existing adsorption rollers generally only possess a single adsorption force suitable for specific films, making it difficult to adapt to the diverse types of films being processed in film manufacturing. Although some products have developed adsorption rollers with adjustable adsorption forces, these products generally require manual operation to adjust the adsorption force, or rely on pre-programmed adjustments. This adjustment method still suffers from low efficiency and cannot adapt to situations involving diverse film types, especially those with irregular variations. The solution of this invention aims to solve this technical problem. Summary of the Invention

It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0040] Figure 2 This is a schematic diagram of the structure of an intelligent control system for an adsorption roller used in thin film processing, as disclosed in an embodiment of the present invention. Detailed Implementation

[0041] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0042] See Figure 1 As shown in the figure, an embodiment of the present invention discloses an intelligent control method for an adsorption roller used in thin film processing, the method comprising the following steps:

[0043] Obtain the first data of the film to be processed;

[0044] The first suction force of the adsorption roller is determined based on the first data;

[0045] The operation of the adsorption roller is controlled according to the first suction force.

[0046] Compared to existing adsorption rollers' adsorption force adjustment methods, the solution in this invention can automatically extract personalized data of the film to be processed and quickly determine the optimal adsorption force that the adsorption roller should apply, so as to achieve good adsorption and transmission effects for different types of films.

[0047] By strategically placing scanning devices at appropriate locations on the adsorption roller equipment, the initial data of the film to be processed can be automatically acquired. These scanning devices can be cameras, readers, etc., and can scan the film roll itself and the identification tags attached to it to obtain the initial data of the film roll. The initial data may include at least one of the following: film type, thickness, color, texture, reflectivity, etc. This initial data is used to determine the inherent characteristics of the film to be processed, thereby determining the subsequent suction force. The camera can be positioned either forward or sideways on the film roll. Positioning it forward facilitates scanning the identification tags (at least obtaining the model number, and other characteristics besides the model number), while positioning it sideways facilitates collecting the thickness characteristics of the film on the roll. Since the reader primarily scans and identifies the data stored in the identification tags, its placement is more flexible. The type, quantity, and configuration of the scanning devices can be freely set according to the actual site conditions, and this invention is not limited thereto.

[0048] In some embodiments, determining the first suction force of the adsorption roller based on the first data includes:

[0049] Based on the first data, the adsorption response data of the film to be processed is estimated, and the first suction force of the adsorption roller is determined based on the adsorption response data.

[0050] In this embodiment, parameters such as the thickness, hardness, and elasticity of the film to be processed directly affect the film's flexibility, thereby determining the film's adsorption response data. The adsorption response data is derived by evaluating and calculating the flexibility and then considering the corresponding error coefficients, and it is positively correlated with the flexibility. Clearly, higher flexibility means better film elasticity, higher adsorption response data, and easier adsorption by the adsorption roller; conversely, lower flexibility makes it more difficult to be adsorbed by the adsorption roller.

[0051] In some embodiments, estimating the adsorption response data of the film to be processed based on the first data includes:

[0052] Determine whether the result of the matching calculation on the first data is not empty;

[0053] If so, the first adsorption response data is determined based on the calculation results;

[0054] If not, the first data is input into the prediction model, and the prediction model outputs the second adsorption response data;

[0055] The first adsorption response data or the second adsorption response data is determined as the adsorption response data.

[0056] In this embodiment, when the film type can be obtained through the aforementioned scanning device, the film's flexibility can be directly determined by looking up a table, thereby determining accurate first adsorption response data. However, when no identification tag is attached to the film roll, the scanning device can only scan and obtain indirect parameters such as the film's thickness, color, texture, and reflectivity. In this case, inputting these indirect parameters into a pre-trained prediction model can match the closest film type, thus predicting relatively accurate second adsorption response data.

[0057] The prediction model can be built and trained using existing types of neural network algorithms. These are not the focus of this invention, and the specific details will not be elaborated here.

[0058] In some embodiments, determining the first suction force of the adsorption roller based on the adsorption response data includes:

[0059] The second suction force of the adsorption roller is determined based on the adsorption response data;

[0060] The adsorption roller is controlled to perform initial adsorption and transmission on the film to be processed according to the second suction force;

[0061] Calculate the transmission difference between the adsorption roller and the support shaft of the film to be processed, determine a correction coefficient based on the transmission difference, and correct the second suction force based on the correction coefficient to obtain the first suction force.

[0062] In this embodiment, the thin film processing equipment includes at least an adsorption roller and a support shaft supporting the roll of film to be processed. By arranging sensors on the axes of the adsorption roller and the support shaft, their rotation data can be acquired. Based on this, the transmission difference between the two after the adsorption roller performs initial adsorption and transmission operations can be calculated. This transmission difference is determined considering the elasticity of the film itself and the response characteristics of each device, and has a certain degree of redundancy. When the transmission difference exceeds a certain threshold, it can be determined that the adsorption roller cannot achieve stable adsorption of the film to be processed according to the second suction force, resulting in adsorption failure, or slippage occurs during transmission. This will lead to excessive deviation in the rotation data of the adsorption roller and the support shaft. To address the above situations, this invention sets up an appropriate correction to the initially determined second suction force based on the aforementioned transmission difference between the two. Preferably, the correction coefficient is set to be positively correlated with the transmission difference.

[0063] It should be noted that since the first adsorption response data is obtained in advance through testing the performance of a known type of thin film, the corresponding second adsorption force is actually accurate (at this time, the first adsorption force is equivalent to the second adsorption force, i.e., no correction is needed). However, the second adsorption response data is predicted and is not completely accurate, so the above-mentioned preliminary adsorption and transmission are required. Preferably, this embodiment can be implemented only when the adsorption response data is the second adsorption response data.

[0064] In some embodiments, the correction coefficient is determined as follows:

[0065] A first correction coefficient is determined based on the transmission difference, and a second correction coefficient is determined based on the second adsorption response data and preset conditions;

[0066] The correction factor is determined based on the first correction factor and the second correction factor.

[0067] In this embodiment, in addition to determining the first correction coefficient using the aforementioned positive correlation, the present invention also considers the second adsorption response data of the film to be processed, which is not entirely accurate and predicted, to determine the second correction coefficient. The two correction coefficients are then combined to determine a more detailed and reasonable correction coefficient. Specifically, the preset condition refers to whether the adsorption response data is lower than the response threshold. When the adsorption response data is lower than the response threshold, it indicates that the flexibility of the film to be processed is poor, and also indicates that it has a stronger tolerance to excessive adsorption forces. In this case, a higher second correction coefficient is set. When the adsorption response data is higher than the response threshold, it indicates that the flexibility of the film to be processed is excellent, and also indicates that it has a lower tolerance to excessive adsorption forces (especially for ultra-thin films used in high-precision fields). In this case, a lower second correction coefficient is set.

[0068] This invention uses a second correction coefficient to adjust the adjustment step of the correction coefficient, thereby adjusting the adjustment step of the second suction force. This enables the optimal suction force search over a large span for films with strong resistance to improve search efficiency; and enables the optimal suction force search over a small span for films with poor resistance to avoid damage to the film during the initial adsorption and transmission process.

[0069] Of course, the initial adsorption and transmission, and correction involved in this embodiment of the present invention can be performed repeatedly until the optimal first suction force is found.

[0070] In some embodiments, the operation of controlling the adsorption roller according to the first suction force includes:

[0071] Acquire second data related to the film to be processed;

[0072] The third suction force and the corresponding switching node are determined based on the first data and / or the second data;

[0073] The switching node controls the adsorption roller to switch operations according to the third suction force.

[0074] In this embodiment, a single film roll is generally wound with a single type of film, but some special film rolls are wound with multiple types of films. These films have different flexibility. If a single suction force is used for adsorption and transmission, it is easy to damage or cause adsorption and transmission failure for subsequent films of other types. In view of this, the present invention also determines a third suction force and corresponding switching node for subsequent new types of films based on the first and / or second data of the film, thereby realizing the use of a new and suitable suction force when adsorbing new types of films on a single film roll, effectively ensuring the continuity and stability of adsorption and transmission operations.

[0075] Before operation, a reader or camera can read the various types of films wound on a single film roll and their respective switching nodes from the identification tag. The switching nodes can be read directly or calculated based on the length of each type of film. Alternatively, they can be calculated by analyzing the thickness distribution of the film roll from the side using image recognition technology; the specific method is not limited. During operation, second data related to the film to be processed can be used. This second data could be the number of rotations / equivalent length of the support shaft supporting the film roll, the number of rotations / equivalent length of the adsorption roller, or the transition area between films of different thicknesses extracted during transmission using image recognition technology, etc. Based on the second data, a third suction force and the corresponding switching node for the new type of film to be adsorbed can be determined. The calculation method for the third suction force is the same as described above and will not be repeated here. That is, the relevant data for determining the third suction force and the corresponding switching node can be obtained before and / or during operation using the aforementioned scanning equipment, specifically depending on the type of scanning equipment provided.

[0076] In some embodiments, controlling the adsorption roller to switch operations according to the third suction force based on the switching node includes:

[0077] The deceleration curve and the adsorption force switching curve of the adsorption roller are determined based on the switching node and the adsorption force difference between the first and third adsorption forces.

[0078] The adsorption roller is controlled to decelerate to the switching node according to the deceleration curve, and the adsorption roller is controlled to switch the first suction force to the third suction force according to the adsorption force switching curve.

[0079] In this embodiment, belt speed switching can try to ensure the continuity of adsorption roller operation to reduce the impact on operation efficiency. However, belt speed switching can also easily cause the original type of film to slip or even detach during the adsorption force change process, which is very detrimental to the guarantee of operation quality.

[0080] To address this, this invention designs a deceleration curve applied before the switching node, and a corresponding adsorption force switching curve. Both curves are calculated based on the adsorption difference generated by the switching node and the corresponding adsorption force switching, thereby achieving gradual deceleration of the adsorption roller and a gradual decrease in adsorption force. This is particularly suitable for situations where the third adsorption force is lower than the first adsorption force. The starting points of the deceleration curve and the adsorption force switching curve can be determined based on the adsorption difference between the first adsorption force of the first type of film and the second adsorption force of the second type of film. The greater the adsorption difference, the farther the starting point is from the switching node.

[0081] It should be noted that the deceleration curve and the adsorption force switching curve can be linear or nearly linear micro-curves. They can have similar curvatures. Specifically, they can be determined based on the starting point data (current speed) and ending point data (adaptation speed corresponding to the second type of film) of the switching between the two. This invention does not limit the specific expression formula of the curve.

[0082] Of course, the suction difference can be positive or negative, and the adaptation speed corresponding to different types of films does not completely correspond to the positive suction difference. Therefore, the deceleration in this invention can also include acceleration, and the deceleration curve and the adsorption force switching curve can also be curves with opposite characteristics. For example, the deceleration curve is a descending curve, while the adsorption force switching curve is an ascending curve. The adaptation speed can be pre-associated with the specific type of film, just like the suction force.
