Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of numerical control, and particularly to a method for controlling abnormal adhesive application on long films, a controller, and a storage medium. Background Technology

[0002] With the continuous improvement of productivity, the requirements for the quality and efficiency of target material strip winding in industry are becoming increasingly higher. How to effectively control the tension of the target material strip during the winding process is an urgent technical problem to be solved. Moreover, this problem has always been a challenge in the manufacturing industry. At present, the main solution to prevent the target material strip from breaking during the winding process is to control the tension by moving the unwinding spring lever up and down. However, this tension control method is an open-loop tension control, which has poor tension control capability. It cannot effectively guarantee the winding quality of the target material strip when the patch length is consistent. Furthermore, when encountering patches with a length value larger than the preset unit patch length value during the adhesive application process, the target material strip is prone to loosening, leading to wrinkles.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0038] With the continuous improvement of productivity, the requirements for the quality and efficiency of target material strip winding in industry are getting higher and higher. How to effectively control the tension of the target material strip during the winding process is an urgent technical problem to be solved. Moreover, this problem has always been a challenge in the manufacturing industry. At present, the main solution to prevent the target material strip from breaking during the winding process is to control the tension by moving the unwinding spring lever up and down. However, this tension control method is an open-loop tension control, which has poor tension control capability. It cannot effectively guarantee the winding quality of the target material strip when the patch length is consistent. When encountering patches with a length value larger than the preset unit patch length value during the adhesive application process, the target material strip is prone to wrinkles due to slack.

[0039] To address the aforementioned problems, this invention provides a method, controller, and storage medium for controlling abnormal adhesive application on long strips. The method includes the following steps: when the length value of the first adhesive strip is greater than the unit length value, the position information of a buffer floating roller is obtained. The first adhesive strip is used to apply adhesive to the target strip. Then, the length value of the first strip is compared with a strip length threshold to obtain a first comparison result, and the position information of the buffer floating roller is compared with preset position information to obtain a second comparison result. Finally, the winding module and / or the main drive module are controlled according to the first and second comparison results to ensure that the position information of the buffer floating roller remains within an movable range during the winding process of the target strip. In the technical solution of this embodiment, the analysis and judgment are performed based on the first comparison result obtained by comparing the first piece length value with the piece length threshold and the second comparison result obtained by comparing the position information of the buffer floating roller with the preset position information. Based on the judgment, the winding module and / or the main drive module are controlled so that the position information of the buffer floating roller is within the movable range during the winding of the target strip. This allows for a thorough analysis of the problems that may occur in the case of long strip abnormalities, thereby solving various problems that may occur in the case of long strip abnormalities, improving the winding quality of the target strip, and preventing the target strip from wrinkling due to looseness during the winding process.

[0040] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, Figure 1 This is a schematic diagram of an adhesive applicator for performing a long-piece abnormal adhesive application control method according to an embodiment of the present invention.

[0042] exist Figure 1In this example, the adhesive applicator 100 includes an adhesive applicator station 110, a main drive module 120, a buffer floating roller 130, a take-up module 140, a detection module 150, and a controller 160. The adhesive applicator station 110 is used for adhesive preparation and applicator operation. The main drive module 120 is used to control the target material strip 170 to enter or leave the adhesive applicator station 110. The buffer floating roller 130 is located outside the main drive module 120 and the take-up module 140. The buffer floating roller 130 is used to move within a movable range according to the tension of the target material strip 170. The motion and winding module 140 is used to wind up the target material strip 170, the detection module 150 is used to detect the position information of the buffer floating roller 130, and the controller 160 is used to control the main drive module 120 and / or the winding module 140 according to the various index data of the adhesive applicator 100 during operation, so that the position information of the target material strip 170 is within the movable range during the winding process, which can effectively prevent the target material strip 170 from being torn or wrinkled, and can effectively improve the winding quality of the target material strip 170.

[0043] It should be noted that the adhesive applicator 100 may also be equipped with an adhesive positioning sensor 181, an unwinding module 182, a deceleration sensor 183, a process correction module 184, an unwinding buffer module 185, etc. This embodiment does not specifically limit the structure of the adhesive applicator 100; those skilled in the art will understand that... Figure 1 The adhesive applicator 100 shown does not constitute a limitation on the embodiments of the present invention. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0044] In one embodiment, during the adhesive application process, the unwinding module 182 and / or the main drive module 120 need to be stopped so that the target strip 170 is also stationary, thus facilitating the adhesive application station 110 to apply adhesive to the target strip 170. However, to maintain the stability of the winding, the winding module 140 can maintain a certain linear speed to stably wind the target strip 170. In this case, if the position of the buffer floating roller 130 is not well controlled, it may cause the buffer floating roller 130 to move to the maximum or minimum value within its movable range, which may result in the target strip 170 breaking or wrinkling. Based on the aforementioned problems, the positioning speed of the main drive module 120 needs to be planned to complete the strip length within a specified time. This can also limit buffer fluctuations caused by arbitrarily setting the strip length and adhesive application time, compensate for buffer fluctuations caused by excessive actual adhesive application or preparation time, and address the issue of long strips. Furthermore, if the adhesive applicator 100 detects that the length of the first adhesive strip exceeds the unit length value during the adhesive application process, it can actively control the winding linear speed of the winding module 140 and / or the speed of the main drive module 120 based on the position information of the buffer floating roller 130 and the length of the first strip. This ensures that the position information of the target strip remains within the movable range during winding, effectively preventing the target strip from breaking and improving the winding quality.

[0045] Based on the aforementioned adhesive applicator, various embodiments of the long-sheet abnormal adhesive application control method of the present invention are presented below. It should be noted that the long-sheet abnormal adhesive application control method of the present invention can be applied not only to adhesive applicators but also to other winding equipment.

[0046] like Figure 2 As shown, Figure 2 This is a flowchart of a method for controlling abnormal long-piece adhesive application according to an embodiment of the present invention. The method for controlling abnormal long-piece adhesive application is applied to the controller in the adhesive application machine, and the method for controlling abnormal long-piece adhesive application includes, but is not limited to, steps S100, S200, S300 and S400.

[0047] Step S100: If the length value of the first piece of the first adhesive film is greater than the unit length value, obtain the position information of the buffer floating roller. The first adhesive film is used to apply adhesive to the target strip.

[0048] Specifically, during the operation of the adhesive applicator, within the same time period and for the same task, adhesive sheets of the same specification are typically processed. Under normal circumstances, the winding module typically does not require intervention. The winding module operates according to a first preset linear speed value, while the main drive module operates according to a first planned speed value. When the length of the first adhesive sheet to be processed is detected to be greater than the unit length value of this adhesive applicator task, the controller needs to obtain the position information of the buffer floating roller during the operation of the adhesive applicator to prevent the target tape from breaking or wrinkling during winding.

[0049] It is understood that the planned speed values ​​(first planned speed value, second planned speed value) of the main drive module are different depending on the corresponding work content at different times, and the controller can be set according to the actual situation. This embodiment does not impose specific limitations on them. Under normal circumstances, the entire planned speed curve of the planned speed values ​​(first planned speed value, second planned speed value) of the main drive module satisfies the following relationship: total positioning time = acceleration time + constant speed time + deceleration time. It can be understood that within the time required for the preparation action before adhesive application, the planned speed value forms a trapezoidal curve in the speed-time coordinate system. (The calculated parameters may include: main drive planned speed, acceleration, deceleration, and jerk (acceleration)). Then, the speed compensation coefficient is obtained based on the position information and the median of the movable range, and the first drive speed value of the main drive module in the adhesive applicator is determined based on the planned speed value and the speed compensation coefficient. For example: Based on the operating conditions, speed compensation is performed for the next unit of film application to ensure that the position of the buffer floating roller is stable within a certain range at the beginning of each operation. First, the main drive speed compensation coefficient is calculated according to the first formula (speed compensation coefficient = (preset position information - position information of buffer floating roller) / 10000). Then, based on the main drive speed compensation coefficient, the speed of the main drive module for the next unit of film application is calculated: drive speed value = planned speed value * (1 + speed compensation coefficient).

[0050] Step S200: Compare the first piece length value with the piece length threshold to obtain the first comparison result.

[0051] Specifically, during normal adhesive application, the main drive module is stopped while the winding module operates at the first planned speed. Therefore, the speed of the main drive module during its uniform positioning is usually greater than the first preset linear speed. So, when encountering a long sheet abnormality, if the length of the first adhesive sheet is too large, the position of the buffer floating roller will be at its maximum range of motion, resulting in wrinkles in the target strip. Therefore, it is necessary to compare the length of the first sheet with the sheet length threshold to obtain the first comparison result. Subsequent steps can then make correct judgments based on the first comparison result, ensuring that the buffer floating roller remains within its range of motion and preventing the target strip from wrinkling due to slack.

[0052] It should be noted that the film length threshold can be set according to the first planned speed value and the first preset linear speed value. For example, it can be the unit film length value plus 1000mm or the unit film length value plus 500mm. This embodiment does not make specific limitations on it.

[0053] Step S300: Compare the position information of the buffer floating roller with the preset position information to obtain a second comparison result.

[0054] Specifically, during the operation of the adhesive applicator, in order to ensure the winding quality of the target material strip, it is necessary to control the winding module and / or the main drive module according to the positional relationship between the position information of the buffer floating roller and the preset position information. The controller can then compare the position information of the buffer floating roller with the preset position information to obtain a second comparison result, which will prepare data for subsequent steps.

[0055] It should be noted that the second comparison result can be the position information of the buffer floating roller being the first position information, where the first position information is located outside the minimum value of the movable range and the preset position information; it can be the position information of the buffer floating roller being the second position information, where the second position information is located outside the maximum value of the movable range and the preset position information; or it can be the position information of the buffer floating roller being the second position information and the position information of the buffer floating roller being greater than the preset position threshold. This embodiment does not specifically limit it.

[0056] It should be noted that the preset position information can be set according to the movable range of the buffer floating roller and the winding quality requirements, and this implementation does not impose specific limitations on it.

[0057] Step S400: Control the winding module and / or the main drive module according to the first comparison result and the second comparison result, so that the position information of the buffer floating roller is within the movable range during the winding of the target strip.

[0058] Specifically, the controller can adjust the winding linear speed of the winding module based on the comparison results. For example, the winding linear speed value of the winding module can be adjusted to a second preset linear speed value, where the first preset linear speed value is smaller than the second preset linear speed value. The winding linear speed value of the winding module can be restored from the second preset linear speed value to the first preset linear speed value. The speed value of the main drive module can be adjusted from the first planned speed value to the second planned speed value. The speed value of the main drive module can be decelerated starting from the first planned speed value. The speed value of the main drive module can also be reduced to 0. This embodiment does not specifically limit the control of the winding module and the main drive module, and can be set according to the actual situation.

[0059] In one embodiment, when the first comparison result is that the first sheet length value is less than the sheet length threshold, and the second comparison result is that the position information of the buffer floating roller is the first position information, the first position information is located outside the range of the minimum value of the movable range and the preset position information. It can be understood that when the first comparison result is that the first sheet length value is less than the sheet length threshold, the problem of wrinkling of the target material strip is unlikely to occur. Therefore, the winding module and / or the main drive module can be controlled according to the second comparison result. When the position information of the buffer floating roller is the first position information, the buffer floating roller is closer to the minimum value in the movable range. If the controller does not intervene, the target material strip may break when the buffer floating roller moves to the minimum value in the movable range. Therefore, the controller can adjust the winding linear speed value of the winding module from the first preset linear speed value to the second preset linear speed value according to the second comparison result. The second preset linear speed value is smaller than the first preset linear speed value. While maintaining the speed value of the main drive module, reducing the winding linear speed value of the winding module can make the buffer floating roller move towards the maximum value in the movable range. Moving upwards can prevent the target material strip from breaking. When the second comparison result shows that the position information of the buffer floating roller moves from the first position information to the second position information, the second position information is located outside the maximum value of the movable range and the preset position information. The buffer floating roller is closer to the maximum value of the movable range. If the controller does not intervene, the target material strip may wrinkle when the buffer floating roller moves to the maximum value of the movable range. Therefore, the controller adjusts the speed value of the main drive module from the first planned speed value to the second planned speed value according to the second comparison result. The second planned speed value is less than the first planned speed value.

[0060] It should be noted that the first preset linear speed value is determined based on the unit length of the adhesive sheet in the target winding tape, the adhesive application time, and the preparation time. The preparation time represents the time required for preparatory actions before applying adhesive to the unit adhesive sheet. To ensure winding efficiency while maintaining stable winding quality, the first preset linear speed value cannot be set too high during actual operation; it needs to be lower than the maximum winding speed limit. Therefore, before operation, the maximum winding speed limit needs to be effectively calculated. This can be done by inputting data such as sheet length, adhesive application time, and adhesive preparation time to the controller. The controller can then calculate the first preset linear speed value based on these parameters. The calculation method for the maximum winding speed limit is as follows:

[0061] First, determine the preparation time value. The preparatory actions before adhesive application mainly include controlling the main drive module to position the unit adhesive sheet and controlling the adhesive application station in the adhesive applicator to prepare the adhesive. Therefore, the data used to determine the preparation time value mainly includes the time required for positioning and the time required for adhesive preparation. Then, select the larger of the two values ​​as the preparation time value. That is, if the time required for positioning is greater than the time required for adhesive preparation, the preparation time value is equal to the time required for positioning; or, if the time required for positioning is less than the time required for adhesive preparation, the preparation time value is equal to the time required for adhesive preparation.

[0062] It should be noted that the adhesive application time of the main drive module is equal to the sum of the positioning time and the adhesive application time. Typically, to ensure a smooth adhesive application process, the positioning time is greater than or equal to the adhesive preparation time. This reduces the risk of the main drive module stopping for too long, which could lead to ineffective control of the buffer floating roller's position. The positioning time is the time required for positioning, and the adhesive preparation time is the time required for adhesive preparation.

[0063] Then, based on the relationship between the winding speed and the sheet length, adhesive application time, and preparation time, the maximum allowable first preset linear speed value for winding is calculated using the following formula. When setting the first preset linear speed value, a speed value smaller than the maximum allowable first preset linear speed value can be selected as the working linear speed of the winding module. The specific formula is as follows:

[0064] Maximum permissible winding speed = Single sheet length / (Adhesive application time + Preparation time) * Preset coefficient / 100.

[0065] It should be noted that the preset coefficient can be 60 or 65. This implementation does not impose a specific limitation on it and can be set according to the specific situation.

[0066] Next, the maximum winding speed limit needs to be determined based on the maximum linear speed of the winding module. The maximum winding speed limit is the minimum value between the maximum permissible winding linear speed and the maximum linear speed of the winding module. For example, if the maximum linear speed of the winding module is 80 meters per minute, and the calculated maximum permissible winding linear speed is 90 meters per minute, then the maximum winding speed limit is 80 meters per minute. That is, when setting the first preset linear speed value, a speed value less than 80 meters per minute can be selected as the working linear speed of the winding module.

[0067] Among the operating parameters of the adhesive applicator, the three parameters of sheet length, adhesive application time, and winding speed can be set and modified individually according to the actual situation. During the setting process, it is easy to encounter problems such as unstable buffering due to unreasonable settings. Now, by linking these parameters together and limiting the maximum winding speed, the stability of buffer control can be effectively guaranteed.

[0068] It should be noted that the adhesive application time can be set to less than 1 second, such as 0.8 seconds or 0.6 seconds. This embodiment does not impose any specific limitation on it.

[0069] It should be noted that the second preset linear speed value is set according to the change in the unit length value of the adhesive film to be processed. The second preset linear speed value is mainly used when the controller detects that the length of the adhesive film is less than the unit length value and the position information of the buffer floating roller is the first position information.

[0070] In one embodiment, when the first comparison result is that the length of the first piece is less than the piece length threshold, and the second comparison result is that the position information of the buffer floating roller moves from the first position information to the second position information, the second position information is located outside the maximum value of the movable range and the preset position information. The buffer floating roller is closer to the maximum value in the movable range. If the controller does not intervene, the target material strip may wrinkle after the buffer floating roller moves to the maximum value in the movable range. Then, the controller can decelerate the speed value of the main drive module from the first planned speed value according to the first comparison result and the second comparison result (it can be uniform deceleration or step deceleration, which is not specifically limited in this embodiment), and restore the winding linear speed value of the winding module from the second preset linear speed value to the first preset linear speed value. This can make the buffer floating roller move in the direction of the minimum value in the movable range, which can prevent the target material strip from wrinkling.

[0071] In one embodiment, when the first comparison result is that the length of the first piece is less than the piece length threshold, and the second comparison result is that the position information of the buffer floating roller moves from the second position information to the first position information, the first position information is located outside the range of the minimum value of the movable range and the preset position information. The buffer floating roller is closer to the minimum value of the movable range. If the controller does not intervene, the target material strip may break after the buffer floating roller moves to the minimum value of the movable range. Therefore, the controller can decelerate the winding linear speed value of the winding module from the first preset linear speed value according to the first comparison result and the second comparison result (it can be uniform deceleration or step deceleration, which is not specifically limited in this embodiment), and restore the speed value of the main drive module from the second planned speed value to the first planned speed value. This can make the buffer floating roller move in the direction of the maximum value of the movable range, which can prevent the target material strip from breaking.

[0072] In one embodiment, if the first comparison result is that the length of the first piece is greater than the piece length threshold, the position information of the buffer floating roller will be at the maximum value of the movable range, which will cause the target material strip to wrinkle. Therefore, the controller needs to control the main drive module to stop working according to the first comparison result and the second comparison result to prevent the target material strip from wrinkling.

[0073] In one embodiment, when the second comparison result indicates that the position information of the buffer floating roller is the second position information and the position information of the buffer floating roller is greater than a preset position threshold, the buffer floating roller is very close to the maximum value in its movable range. The buffer floating roller will reach the maximum value of its movable range in a very short time. Therefore, the controller must control the main drive module to stop working immediately according to the first comparison result and the second comparison result to prevent the target material strip from wrinkling. It should be noted that the preset position threshold represents the position information in the second position information that is closer to the maximum value in the movable range of the buffer floating roller. This embodiment does not specifically limit it. For example, in order to prevent the buffer floating roller from reaching the upper limit (the maximum value of the movable range is 1000), the second position information is in the range of 800 to 1000. The preset position threshold can be 20, that is, when the buffer floating roller is 20 below the maximum value of the movable range, the controller calls STOP in advance to stop the main drive motor.

[0074] Reference Figure 3 As shown, in Figure 2 The method for controlling abnormal adhesive application on long films after step S400 also includes, but is not limited to, the following steps:

[0075] In step S310, when the second film is being applied, the second film is the next film applied after the first film, and the winding module is controlled according to the third preset linear speed value.

[0076] Specifically, after processing the first film with the problem of long film, various situations may occur due to the control and adjustment of the first film with the abnormality of long film. The position information of the buffer floating roller may not be within the preset position information after the adhesive application task of the first film is completed. In order to enable the subsequent adhesive application machine to return to normal operation, when processing the second film (the film after the first film), the winding module can be controlled according to the third preset linear speed value to effectively adjust the position information of the buffer floating roller at a relatively slow working speed.

[0077] Step S320: Obtain the position information of the buffer floating roller and the length value of the second piece of the second film.

[0078] Specifically, refer to Figure 4 If the linear speed of the winding module is kept at the third preset linear speed value, and the speed of the main drive module is not intervened, the buffer floating roller will move quickly towards the maximum value of its movable range because the speed of the main drive module is relatively fast and the linear speed of the winding module is relatively slow. This will cause the target material strip to wrinkle. Therefore, the controller needs to intervene in the speed of the main drive module. Calculating the speed of the main drive module requires three data points: the position information of the buffer floating roller, the third preset linear speed value, and the second length value of the second film. Therefore, the controller needs to obtain the position information of the buffer floating roller and the second length value of the second film.

[0079] Step S330: Determine the third planned speed value of the main drive module based on the position information of the buffer floating roller, the third preset linear speed value, and the second piece length value.

[0080] Specifically, firstly, the adhesive application running time of the main drive module in the adhesive applicator is determined based on the third preset linear speed value and the second piece length value of the winding module. Then, the adhesive application time value is obtained, and the positioning time value is derived based on the adhesive application running time value and the adhesive application time value. Next, the planned speed value is determined based on the positioning time value and position information. For example, the HC_HighSpeedcontrol function module is used to calculate the speed based on the piece length value and the adhesive application running time value. The calculated parameters are then set into the control program of the main drive module. The main drive module will run according to the planned speed value and stop after completing the piece length positioning. The entire planned speed curve satisfies the following relationship: Total piece length during positioning time = Piece length during acceleration + Piece length during constant speed + Piece length during deceleration. This can be understood as the planned speed value forming a trapezoidal curve in the speed-time coordinate system within the time required for preparatory actions before adhesive application. (The calculated parameters may include: main drive planned speed, acceleration, deceleration, and jerk (acceleration)). Then, based on the position information and the midpoint of the movable range, the speed compensation coefficient is obtained. Next, based on the planned speed value and the speed compensation coefficient, the first drive speed value of the main drive module in the adhesive applicator is determined. For example: based on the operating conditions, speed compensation is applied to the next unit of adhesive application to ensure that the position of the buffer floating roller remains stable within a certain range at the start of each operation. First, the main drive speed compensation coefficient is calculated using the first formula (speed compensation coefficient = (preset position information - buffer floating roller position information) / 10000). Then, based on the main drive speed compensation coefficient, the speed of the main drive module for the next unit of adhesive application is calculated: Drive speed value = planned speed value * (1 + speed compensation coefficient).

[0081] It should be noted that the preset position information can be the median of the movable range of the buffer floating roller, or other position values ​​near the median of the movable range of the buffer floating roller. It can be set according to the actual situation, and this embodiment does not impose any specific limitations on it.

[0082] It should be noted that during the preparation time required before applying the adhesive, the preset planned speed value forms a trapezoidal curve or an arc curve in the speed-time coordinate system. This implementation does not specifically limit it.

[0083] Step S340: Control the main drive module according to the third planned speed value so that the position information of the buffer floating roller is within the preset position information during the winding of the target strip.

[0084] Specifically, refer to Figure 4When the linear speed of the winding module is the third preset linear speed value, the main drive module can be controlled according to the drive speed value corresponding to the speed curve of the main drive module, so that the position information of the buffer floating roller fluctuates within a reasonable preset position information during the winding of the target strip. It can be understood that after completing the adhesive application of the second film, when applying adhesive to the third film that meets the unit length value, both the main drive module and the winding module can resume operation at the first planned speed value and the first preset linear speed value under normal conditions.

[0085] It should be noted that, Figure 4 This is just one schematic embodiment of the correspondence between the winding linear speed curve, the main drive module speed curve, and the buffer fluctuation curve representing the position information of the buffer floating roller. This embodiment does not limit the correspondence between the three to a single one, and there may be other correspondences.

[0086] It should be noted that the preset location information is smaller than the movable range. For example, the preset location information can be half of the movable range, two-thirds of the movable range, or a range within the movable range. This embodiment does not specifically limit the preset location information and can set it according to the actual product quality control needs.

[0087] It should be noted that the preset position information (range information) smaller than the movable range can include the range near the midpoint of the movable range, the range near the top of the movable range, or the range near the bottom of the movable range. This embodiment does not specifically limit it and can be set according to the actual product quality control needs.
