[0028] Localized adhesive removal during lamination refers to a technique that removes the adhesive or adhesive layer from a specific area of a material surface during production or processing, while leaving the adhesive layer in other areas intact. This process is primarily used when partial bonding is required or when localized adhesive surface treatment is required.

[0029] The pull-tab in the related art has a 3-7mm head with glue removal and a 2mm wide glue removal strip. The length of the glue removal strip is 4-8mm left at the knife hole, which is adjusted according to the size and position of the pull-tab. The pull-tab has residual glue left on the packaging bag, which is easy to contaminate the objects in the packaging bag. The pull-tab is easy to warp at the tail and above and below the pull-tab. The pull-tab is severely deformed and difficult to re-stick.

[0030] Based on this, in order to improve the problem in the related art that residual glue is left on the packaging bag due to the degumming process, which makes it difficult to re-paste and easy to warp and deform the label, the embodiment of the present application provides the following solution.

[0031] See also Figure 1 In a first aspect, an embodiment of the present application provides a method for removing adhesive from a local adhesive layer, comprising:

[0032] S1, providing a pull label of a preset material used at the opening of the packaging bag.

[0033] It can be understood that the pull-on sticker that meets the preset material can be a pull-on sticker that meets the pre-selected material; the pull-on sticker that meets the pre-selected material can be a pull-on sticker of different materials selected according to different products; the preset material can be a material that meets the requirements of different products obtained through experimental verification or analysis.

[0034] S2, applying adhesive glue to the tearing portion of the pull label.

[0035] It can be understood that the sticky glue is applied to the torn portion of the pull-tab; the torn portion can be the area where the pull-tab is attached to the packaging bag and the sticky glue is applied.

[0036] This arrangement can provide additional adhesive force when the pull label is torn open and then closed again, making the seal of the packaging bag tighter.

[0037] In one possible implementation, the adhesive glue is placed before the tearing portion of the pull label, and the method further includes:

[0038] S2A, obtain an acrylate polymer, a tackifying resin, and a cross-linking agent in sequence, and mix them in a mass ratio of 80:15:5.

[0039] It can be understood that the mixing in the mass ratio of 80:15:5 can be achieved by first stirring and mixing the acrylic ester polymer in a mass ratio of 80, the tackifying resin in a mass ratio of 15, and the cross-linking agent in a mass ratio of 5.

[0040] With such settings, the acrylate polymer itself has a certain viscosity. However, with the addition of the tackifying resin at a mass ratio of 15%, it helps to enhance its adhesion to the surfaces of different materials. After the crosslinking agent is added at a mass ratio of 5%, a crosslinked structure can be formed between the acrylate polymer and the tackifying resin, enhancing the intermolecular interaction. The adhesive formed under this mixing ratio can maintain the stability of its shape and viscosity when subjected to external tensile and compressive forces; when the pull-tab is repeatedly opened and closed, the adhesive can withstand a certain degree of deformation without damage, enabling the pull-tab to always work properly.

[0041] S2B, place the acrylate polymer, the tackifying resin, and the crosslinking agent in a stirring tank, stir for 30 - 60 minutes, and let it stand for defoaming for 2 - 4 hours. Then, filter it using a filter and detect the viscosity and solid content to obtain a viscous glue; among them, the viscosity is in the range of 2000 - 3000 mPa·s, and the solid content is 40% - 50%.

[0042] It can be understood that first put the acrylate polymer into the stirring tank, then put the tackifying resin into the stirring tank for stirring, and finally add the crosslinking agent for stirring. Stir for 30 - 60 minutes, and let it stand for defoaming for 2 - 4 hours. Then, obtain a viscous substance through filtration. Stirring for 30 - 60 minutes can be 30, 33, 35, 38, 40, 42.5, 45, 47.5, 50, 52, 55, 58, or 60, etc., and letting it stand for defoaming for 2 - 4 hours can be 2h, 2.5h, 3h, 3.5h, or 4h, etc., but not limited to this. The stirring tank can be a conventional stainless - steel stirring tank, and the filter can be a scraper - type self - cleaning filter, etc., but not limited to this. The stirring tank includes a stirring chamber, a stirring rod, a transmission mechanism, etc. The stirring rod is located in the stirring chamber and is used to evenly mix the preparation raw materials in the stirring chamber. The output end of the transmission mechanism is connected to the stirring rod and is used to enable the stirring rod to perform stirring. The transmission mechanism can be a motor, a stepless speed variator, etc., but not limited to this.

[0043] With such settings, stirring for 30 - 60 minutes can allow the acrylate polymer, the tackifying resin, and the crosslinking agent to fully contact and be evenly mixed; the properties of each part of the evenly mixed substance are the same, making the properties such as adhesion and stability of the viscous substance the same at different positions, avoiding the situation of overly strong or overly weak local viscosity. Letting it stand for defoaming for 2 - 4 hours can eliminate the bubbles mixed in during the stirring process, making the structure of the viscous substance more dense. When applied to the pull - tab, it will not cause voids or defects in the coating due to bubbles, improving the sealing performance and adhesion effect of the pull - tab. Removing impurities and unreacted particles through filtration, detecting the viscosity and solid content and making them reach the range of 2000 - 3000 mPa·s and 40% - 50% can accurately control the properties of the viscous substance. The appropriate viscosity is conducive to good fluidity and adhesion during the coating process, and the solid content directly affects the drying speed and final adhesive strength of the viscous substance, meeting the actual use requirements.

[0044] S3. Apply a wire mesh degumming process to the torn part of the pull tab to form a wire mesh degummed part on the torn part.

[0045] With such a setting, a wire mesh degumming process is performed in the tear area of the pull tab. The wire mesh weakens the local adhesiveness of the pull tab, reducing the difficulty of tearing caused by the adhesion of the adhesive layer. Degumming the torn part can avoid the pollution of glue residues that might originally be caused by the adhesion of the adhesive layer, preventing consumers from coming into contact with unnecessary adhesive layers or sticky substances. The wire mesh degumming treatment can avoid local strength differences in the torn part due to uneven adhesive layers. When tearing, the packaging bag is more evenly stressed, avoiding tearing damage caused by the adhesive layer being too hard or having too strong adhesiveness during tearing.

[0046] In a possible implementation, S3. Apply a wire mesh degumming process to the torn part of the pull tab to form a wire mesh degummed part on the torn part.

[0047] S31. In the wire mesh degumming process, the width of the wire mesh is 0.15 - 0.2 mm, and the wire mesh spacing is 0.2 - 0.5 mm. The dosage of the viscous glue is controlled at 10 - 15 g / m 2 .

[0048] It can be understood that in the wire mesh degumming process, it is composed of multiple wire meshes; the width of the wire mesh is the width of a single wire mesh, and its width can be 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, etc., but not limited to this. The wire mesh spacing is the distance between adjacent wire meshes (single wire meshes), and its wire mesh spacing can be 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc., but not limited to this.

[0049] With such a setting, the combination of the wire mesh width (0.15 - 0.2 mm), wire mesh spacing (0.2 - 0.5 mm), and the dosage of the viscous glue (10 - 15 g / m 2 ) can make the distribution of the glue in the torn part uniform and appropriate. The fine wire mesh can better control the glue layer in the torn part of the packaging bag, avoiding excessive or insufficient glue residues and ensuring the smoothness during tearing. In addition, the appropriate wire mesh spacing and width can ensure that the torn part has sufficient toughness and strength, while avoiding the glue being too sticky or uneven.

[0050] In a possible implementation, the material of the pull tab is a plastic film material, and the thickness of the pull tab is 0.17 - 0.25 mm.

[0051] It can be understood that the thickness of the pull-tab can be 0.17 mm, 0.18 mm, 0.19 mm, 0.20 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm or 0.25 mm.

[0052] With such a setting, the plastic film has strong toughness and tensile resistance, and is more suitable for use as a packaging material, capable of withstanding a certain amount of external tensile force without being easily torn. A thickness of 0.17 - 0.25 mm for the pull-tab can enable the pull-tab bag to have sufficient strength, avoiding unnecessary tearing or damage when being torn open.

[0053] In a possible implementation, the adhesive glue is a water-based pressure-sensitive adhesive; the water-based pressure-sensitive adhesive includes an acrylate polymer, a tackifying resin, and a cross-linking agent.

[0054] Exemplarily, the acrylate polymer, as the main polymer, provides good adhesion performance and weather resistance. The tackifying resin helps to enhance the adhesive force of the water-based pressure-sensitive adhesive and strengthen its adhesion ability to various surface materials; the cross-linking agent can enhance the durability and stability of the water-based glue, improve the persistence of the glue, and avoid the problem of reduced viscosity after long-term use.

[0055] With such a setting, the water-based pressure-sensitive adhesive uses water as a solvent and does not contain harmful solvents. The water-based pressure-sensitive adhesive can bond in a short time, is suitable for rapid fitting and sealing in large-scale production processes, reduces waiting time, and improves production efficiency.

[0056] In a possible implementation, please refer to Figure 2 , S3, using a wire mesh degumming process to degum the torn part of the pull-tab so that the torn part forms a wire mesh degummed part, including:

[0057] S100, obtaining the area to be degummed of the torn part of the pull-tab; wherein, the material of the pull-tab is a plastic film material, and the area to be degummed is the area to be degummed after applying glue to the pull-tab.

[0058] It can be understood that the area to be degummed can be a partial area or the entire area of the torn part. The area to be degummed on the pull-tab is to apply the adhesive glue on the pull-tab and degum the glue applied on the pull-tab, and the determined degummed area is the area to be degummed; applying the adhesive glue on the pull-tab is to apply it on the side of the pull-tab in contact with the packaging bag. Obtaining the area to be degummed can be done after applying the adhesive glue on the pull-tab, and then using a camera or an image collector to collect an image of the pull-tab.

[0059] In a possible implementation, please refer to Figure 3 , S100, obtaining the area to be degummed of the torn part of the pull-tab, including:

[0060] S110, obtain dimension data; wherein, the dimension data is used to indicate the length value and width value of the packaging bag.

[0061] It can be understood that the packaging bag can be various specific products, such as a tissue packaging bag, a sanitary napkin packaging bag, etc., but not limited thereto. The length value and width value of the packaging bag can be determined by the actual size of the specific product, can also be obtained by direct measurement or by referring to the design document; the design document will have design drawings or specification sheets before the production of the packaging bag. The design document is designed by the designer according to factors such as the size, shape, and packaging requirements of the product, and includes the accurate length and width values of the packaging bag, as well as other relevant dimension information, etc., but not limited thereto.

[0062] S120, determine the latching parameters data according to the length value and width value indicated by the dimension data; wherein, the latching parameters data is used to indicate the length value and width value of the latching.

[0063] It can be understood that, according to the length value and width value indicated by the dimension data, as well as the opening method and the actual usage frequency of the item, the length value indicated by the latching parameters data is obtained. According to the length value and width value indicated by the dimension data, as well as the material and thickness of the packaging bag, the width value indicated by the latching parameters data is obtained;

[0064] Exemplarily, according to the length value and width value indicated by the dimension data, as well as the opening method and the actual usage frequency of the item, the length value indicated by the latching parameters data is obtained. Based on the opening method, if the packaging bag is a single-sided opening, the latching length is slightly less than the side length of the opening, which can be less than 1 cm or 2 cm; for example, for a packaging bag with an opening side length of 20 cm, the latching length can be set to 18 cm. If the packaging bag is a double-sided opening or a multi-sided opening, the latching length covers the main opening part and can effectively play a role in different opening directions, and can be determined according to a certain ratio, such as 30%, 35%, 40%, or 50% of the opening perimeter, etc., but not limited thereto. For packaging bags that need to frequently access the contents, such as snack bags, in order to facilitate multiple opening and closing operations, the latching length is increased by 3 cm or 4 cm. According to the length value and width value indicated by the dimension data, as well as the material and thickness of the packaging bag, the width value indicated by the latching parameters data is obtained. Combining the material and thickness of the packaging bag, for a relatively thin soft packaging bag, such as a plastic film bag, the latching width can be 1 cm, 1.2 cm, 1.3 cm, 1.4 cm, or 1.5 cm, etc., but not limited thereto; for a relatively thick rigid packaging bag, such as a cardboard box, the latching width can be 1.5 cm, 1.8 cm, 2 cm, 2.3 cm, 2.4 cm, or 2.5 cm, etc., but not limited thereto.

[0065] S130, perform a region analysis based on the length value and width value of the packaging bag indicated by the size data and the length value and width value of the pull-and-paste indicated by the pull-and-paste parameter data to obtain the area to be degummed.

[0066] It can be understood that by calculating based on the length value and width value of the packaging bag indicated by the size data and the length value and width value of the pull-and-paste indicated by the pull-and-paste parameter data, the area to be degummed is obtained; the calculation formula is: L q = L l + 2×Y; W q = W l + 2×Y; L q is the length of the area to be degummed, L l is the length of the pull-and-paste, W q is the width of the area to be degummed, W l is the width of the pull-and-paste, Y is the reserved space, and the value is a constant; then multiply L q ×W q The result obtained is determined as the area to be degummed.

[0067] In a possible implementation, please refer to Figure 4 , S130, perform a region analysis based on the length value and width value of the packaging bag indicated by the size data and the length value and width value of the pull-and-paste indicated by the pull-and-paste parameter data to obtain the area to be degummed, including:

[0068] S131, perform a requirements analysis based on the length value and width value of the packaging bag indicated by the size data and the length value and width value of the pull-and-paste indicated by the pull-and-paste parameter data to obtain requirement data; among them, the requirement data includes the requirement for paste stability and the requirement for tear convenience.

[0069] It can be understood that the requirement for paste stability is that the pull-and-paste is used to paste on the packaging bag, and there needs to be a paste area in the non-torn state to meet the sealing of the packaging; assuming the length of the pull-and-paste is L1 and the width is W1, for a relatively large packaging bag (length L2, width W2), the pull-and-paste needs to provide a relatively greater adhesive force to withstand possible external forces, and the proportion of the length of the degumming area to the length of the pull-and-paste can be relatively small, and the length of the degumming area can be between 30%, 40% or 50%, so that the pull-and-paste has sufficient paste area in the non-torn part. For a relatively small packaging bag, the pull-and-paste itself is relatively small, and it can be between 40%, 50% or 60%. The requirement for tear convenience is considered from the perspective of tear convenience, and the width of the degumming area is the proportion of the width of the pull-and-paste. For example, when the width W1 of the pull-and-paste is greater than 20 mm, the proportion of the width of the degumming area can be between 40%, 50% or 60%; when the width of the pull-and-paste is between 10 - 20 mm, the proportion of the width of the degumming area can be between 30%, 40% or 50%.

[0070] Exemplarily, the length L2 of a packaging bag is 200 mm, the width W2 is 100 mm, the length L1 of the pull-tab is 100 mm, and the width W1 is 20 mm. According to the above ratio relationship considering the pasting stability and the tearing convenience, the length of the degumming area can be determined to be 40 mm - 50 mm (accounting for 40% - 50% of the pull-tab length), and the width of the degumming area can be 8 mm - 12 mm (accounting for 40% - 60% of the pull-tab width). If the length L2 of another packaging bag is 100 mm, the width W2 is 60 mm, the length L1 of the pull-tab is 60 mm, and the width W1 is 10 mm. At this time, the length of the degumming area can be 30 mm - 36 mm (accounting for 50% - 60% of the pull-tab length), and the width of the degumming area can be 3 mm - 5 mm (accounting for 30% - 50% of the pull-tab width).

[0071] S132. Determine a preset degumming area according to the demand data, and perform characteristic detection on the preset degumming area to obtain area detection data; wherein, the area detection data is used to indicate the stress value and deformation value of the pull-tab obtained through the characteristic test.

[0072] It can be understood that the preset degumming area is the preset degumming position on the pull-tab; determine the preset degumming area according to the demand data, and perform stress and deformation calculations on the preset degumming area to obtain area detection data; the stress calculation formula is:[[]] σ is the stress, F is the tensile force acting on the pull-tab (unit: Pa), A is the stress-bearing area of the pull-tab (unit: m 2 ); the deformation calculation formula is:[[]] ΔL is the amount of deformation (unit: m), L is the original length of the pull-tab (unit: m), E is the elastic modulus of the material (unit: Pa), and determine the values of σ and ΔL as the area detection data.

[0073] S133. Compare the stress value and deformation value indicated by the area detection data with the preset threshold. If the stress value and deformation value indicated by the area detection data are both less than the preset threshold, the preset degumming area is determined as the degumming area.

[0074] Exemplarily, compare the stress value and deformation value indicated by the area detection data with the preset threshold. If both the stress value and deformation value are less than the preset threshold, it proves that the stress value and deformation value indicated by the area detection data are within the bearing range of the pull-tab, and the preset degumming area is determined as the degumming area. The preset threshold can be obtained by testing the stress value and deformation value of the pull-tab material, or can be obtained from the historical usage records, etc., but not limited to this. By judging the numerical difference between the stress value and deformation value and the preset threshold, it is possible to timely understand whether the preset degumming area meets the requirements of the degumming area, saving time and laying a foundation for the follow-up.

[0075] In a possible implementation, the method further includes:

[0076] If the area detection data is used to indicate that both the stress value and the deformation value after testing are greater than a preset threshold, adjustment data is obtained; wherein, the adjustment data is used to indicate area adjustment of a preset debonding area.

[0077] Exemplarily, the stress calculation formula according to step S132 above is For the obtained stress value, the deformation calculation formula When both the obtained deformation value and the stress value are greater than a preset threshold, area adjustment is performed on the preset debonding area. By expanding the preset debonding area to reduce the stress value and the deformation value, a new preset debonding area is obtained. The new preset debonding area and the preset debonding area before adjustment are overlapped, and the non-overlapped area between the new preset debonding area and the preset debonding area before adjustment is determined as the adjustment data.

[0078] With such a setting, by adjusting the preset debonding area, the stress distribution can be made more uniform, the degree of local stress concentration can be reduced, thereby improving the stability and reliability of the entire structure, reducing problems such as cracking and deformation caused by excessive stress, reducing quality fluctuations and defective rates caused by stress and deformation problems, and enhancing the overall quality level and reliability.

[0079] S200, obtaining debonding environment data; wherein, the debonding environment data is used to indicate the environmental temperature, environmental humidity, and debonding path when debonding the area to be debonded.

[0080] Exemplarily, obtaining the environmental temperature and environmental humidity can be achieved through a temperature and humidity sensor, such as digital temperature and humidity sensors like DHT11 and SHT30; the sensor can be connected to the control device through a communication method. The control device reads the temperature and humidity data measured by the sensor at a set time interval; obtaining the debonding path can be achieved by setting parameters for debonding path planning according to debonding process requirements, such as debonding coverage rate, adjacent path spacing, width of a single path, starting point and ending point, etc., and can also be retrieved from a database for the size of the packaging bag and the pull patch and the material of the pull patch; the database is a storage system that can count and record the paths used in history.

[0081] S300, performing debonding analysis on the debonding environment data to obtain debonding data; wherein, the debonding data is used to indicate that the debonding environment data meets the debonding operation.

[0082] Exemplarily, the environmental temperature, environmental humidity, and degumming path indicated by the degumming environment data are respectively compared with the thresholds of the environmental temperature, environmental humidity, and degumming path in history. The situation that meets the thresholds of the environmental temperature, environmental humidity, and degumming path in history is determined as degumming data.

[0091] It can be understood that the physical properties include tensile properties, adhesion properties, and thermal expansion properties.

[0092] Exemplarily, according to the model of the plastic film material for temperature and humidity: R(T, H) = αT·(T - T0) + αH·(H - H0) for calculation, obtain the response value R(T, H) of the plastic film material, and determine the response value R(T, H) of the plastic film material as the influence value of the environmental temperature and environmental humidity indicated by the influence data on the physical properties of the plastic film material; αT and αH are the sensitivity coefficients of the material to temperature and humidity changes, and R(T, H) is the response value of the plastic film material.

[0093] S322. Perform multi-point temperature and humidity detection on the influencing data to obtain temperature and humidity data. Among them, the temperature and humidity data is used to indicate a 3D heat map of the environmental temperature and humidity distribution, and the 3D heat map is used to reflect the gradient state of the environmental temperature and humidity.

[0094] It can be understood that multi-point temperature and humidity detection can be understood as the temperature and humidity values at different positions collected by multi-region distributed temperature and humidity sensors.

[0095] Exemplarily, according to the temperature and humidity values at different positions collected by the multi-region distributed temperature and humidity sensors, through the environmental model D e ={(T i , H i )|i = 1, 2, …, n} for calculation, T i , H i respectively represent the i-th environmental temperature value and environmental humidity value, and then through D e ={(T i , H i )|i = 1, 2, …, n} and the sensor data to obtain a 3D heat map of the temperature and humidity distribution, and determine the gradient conditions of the environmental temperature and humidity in the 3D heat map as the temperature and humidity data.

[0096] S323. Optimally adjust the environmental temperature and humidity according to the 3D heat map indicated by the temperature and humidity data to obtain the first satisfied data.

[0097] Exemplarily, the ambient temperature and ambient humidity shown in the 3D heat map are respectively divided into two regions. The distribution of temperature in the entire space is viewed from the 3D heat map. The positions and ranges of the high-temperature region and the low-temperature region are determined according to the temperature values on the 3D heat map. By comparing the temperature values on the 3D heat map with the preset temperature standard value, a temperature anomaly region with a large ambient temperature difference is obtained. The temperature at the position corresponding to the temperature anomaly region with a large difference is increased or decreased to make corresponding adjustments. The adjustment situation (the adjustment situation can be whether the temperature at a specific position is increased or decreased and the increased temperature value or the decreased temperature value) is used as temperature adjustment data. Then, the ambient temperature and ambient humidity shown in the 3D heat map are respectively divided into two regions. The distribution of humidity in the entire space is viewed from the 3D heat map. The positions and ranges where different humidity conditions are located are determined according to the humidity values on the 3D heat map. By comparing the humidity values on the 3D heat map with the preset humidity standard value, a humidity anomaly region with a large ambient humidity difference is obtained. The humidity at the position corresponding to the humidity anomaly region with a large difference is increased or decreased to make corresponding adjustments. The adjustment situation (the adjustment situation can be whether the humidity at a specific position is increased or decreased and the increased humidity value or the decreased humidity value) is used as humidity adjustment data. The temperature adjustment data and the humidity adjustment data are determined as the first satisfied data. The method for judging the humidity difference region is to compare the humidity value at any position or region in the 3D heat map with the preset humidity standard value. If it is greater than 40% of the preset humidity standard value, the humidity situation at this position is determined as a humidity anomaly position with a large ambient humidity difference. The method for judging the temperature difference region is the same and will not be elaborated here.

[0098] S330. Analyze the de-glue path indicated by the de-glue environment data to obtain second difference data; wherein, the second difference data is used to indicate the influence of the de-glue path indicated by the de-glue environment data on the plastic film material.

[0099] Exemplarily, the second difference data is used to indicate the influence value of the de-glue path indicated by the de-glue environment data on the plastic film material; the path influence model is R p = f(L p , P p , V p ); R p represents the influence value of the de-glue path on the plastic film material, L p is the length of the de-glue path, P p is the glue layer distribution density on the path, V p is the de-glue speed; by establishing a path influence model of the de-glue path on the plastic film, the R p obtained by analyzing the de-glue path indicated by the de-glue environment data through the path influence model, and R p is determined as the second difference data; Rp Denoted as the influence value of the degumming path on the plastic film material, where the influence value can be the degree of deformation of the film, the residual gum rate, etc., but is not limited thereto.

[0100] S340, optimize the second difference data to generate second satisfaction data; wherein, the second satisfaction data is used to indicate the situation of the optimized degumming path.

[0101] It can be understood that the performance value of the optimized degumming path indicated by the second satisfaction data. According to the path influence model, it is R p = f(L p , P p , V p ) combined with the degumming environment data to obtain the formula ΔP a = R a -R i ; wherein, R a is the influence of the actual degumming path on the film material, R i is the influence of the target degumming path on the film material under ideal conditions, ΔP a is the difference value of the degumming path on the film material. Convert ΔP a into an objective function, f0 = ω1·ΔR p +ω2·Δde+ω3·Δre; wherein, f0 represents the overall performance after path optimization, ω1 is the weight affecting the actual influence difference of the path on the plastic film, ω2 is the weight affecting the film deformation, ω3 is the weight affecting the residual gum amount; ΔR p is the difference value of the degumming path; Δde is the difference in film deformation, indicating the influence of the degumming path on the morphological change of the film. Film deformation usually refers to the deformation of the material caused by mechanical force or thermal force during the degumming process. If the deformation caused by the degumming path is smaller, the smaller it is, the smaller the influence of the optimized path on the film; Δre is the difference in residual gum, that is, the amount of the remaining glue layer on the film surface after degumming; the less the residual gum, the better the path optimization effect; if the degumming path can effectively remove the glue layer, the amount of residual gum will decrease, and thus Δre will be smaller. Determine the f0 calculated from the second difference data according to f0 = ω1·ΔR p +ω2·Δde+ω3·Δre as the second satisfaction data. f0 can have a standard, and the performance standard can be determined according to the size of the value of f0. For example, the values of f0 corresponding to level 1, level 2, and level 3 of the performance standard are A, B, and C, and A > B > C. The value calculated by f0 = ω1·ΔR p +ω2·Δde+ω3·Δre is ≥ C and ≤ A.

[0102] With such settings, the degumming path can be made more in line with the characteristics of the plastic film material, reducing problems such as material damage and incomplete degumming caused by an unreasonable path, further improving the overall quality level and reliability. By analyzing and optimizing the ambient temperature, ambient humidity, and degumming path, the degumming operation can be carried out under optimal conditions, improving the degumming efficiency and effect, reducing production costs, and enhancing the market competitiveness of the product.

[0103] In a possible implementation, refer to Figure 7 , S340, optimize the second difference data to generate second satisfaction data, including:

[0104] S341, establish an influence equation of the current degumming path on the plastic film material, and use the influence equation for calculation to obtain the influence factors of the degumming path on the plastic film; among them, the influence factors include the surface residual glue rate and the film deformation rate.

[0105] Exemplarily, through the surface residual glue rate formula of the current degumming path on the plastic film material and the film deformation rate formula and use the surface residual glue rate formula and the film deformation rate formula to obtain the surface residual glue rate R r and the film deformation rate D d of the degumming path on the plastic film; where, R r is the surface residual glue rate, D d is the film deformation rate, G r is the mass of the residual glue on the film surface after degumming, G i is the mass of the initial glue layer, A d is the area or thickness of the film after deformation, A i is the area or thickness of the film before degumming.

[0106] S342, based on the influence factors, and divide the degumming path into multiple path segments according to the path complexity, and detect the degumming path of each path segment to obtain change data; where, the change data is used to indicate the path change situation of each path segment, and the path complexity is used to indicate the path composition part of the degumming path, and the path composition part includes a straight part and a curved part.

[0107] Exemplarily, based on the impact factor and according to the path components, the degumming path is divided into multiple path segments, and the degumming path of each path segment is detected to obtain variation data. The straight part can be understood as a straight path, and the curved part is a bent path, and the bent path includes an arc path, an S-shaped path, and a semi-circular path. The path variation of each path segment indicated by the variation data can be understood as having several position turning changes in the bent path. For example, if a curved path is S-shaped, then this curved path has two turning changes. Therefore, the two turning changes divide the S-shaped curved path into three different path segments, and the changes such as residual glue change, deformation change, speed change, and pressure change at these two turning points are determined as the variation data.

[0108] S343. Perform a difference analysis on the path variation of each path segment indicated by the variation data and the plastic film material to obtain difference result data; wherein, the difference result data is used to indicate the difference score of each path segment.

[0109] It can be understood that the difference analysis is the influence of each path segment (including the straight segment and the curved segment) on the plastic film material (such as the glue layer of the film, the surface residual glue rate, the degree of deformation, etc.). The difference score of each path segment indicated by the difference result data gives a score according to the influence of each path segment on the film material, which is used to represent the degumming effect and the quality change of the film material. The difference score formula is: Take the obtained D s of the difference score value as the difference result data. Wherein, D s is the difference score of the i-th path segment, representing the difference between the path segment change and the film material response, (X s , i) is the variation data of the i-th path segment, and (Y s , i) is the film response data of the i-th path segment. The higher the D s (difference score), the greater the influence of this path segment on the film material. The obtained D s value can be compared with the D s value that met the requirements in history or compared with the ideal D s . The D s value that met the requirements in history can be extracted from the system, and the system can be a storage system that stores the D s value that met the requirements. According to the actual number of path segments, the difference scores of each path segment are calculated according to the above formula, which will not be elaborated here one by one.

[0110] S344. Perform path adjustment according to the difference scores of each path segment indicated by the difference result data to generate second satisfaction data.

[0111] It can be understood that based on the difference scores of each path segment indicated by the difference result data, each path segment is adjusted by using the adjusted ashing speed, ashing pressure, and the curvature of the path segment to generate second satisfaction data. The adjustment is carried out by using the adjusted ashing speed parameter, ashing pressure parameter, and the curvature of the path segment.

[0112] Exemplarily, according to the formula: and where, v n is the ashing speed of the adjusted path segment, v c is the ashing speed of the current path segment, S M is the maximum difference score among all path segments, P n is the ashing pressure of the adjusted path segment, P c is the ashing pressure of the current path segment, θ n is the curvature of the current path segment, θ c is the adjusted curvature. v n , P n and θ n are determined as the second satisfaction data.

[0113] S350, generate ashing data according to the first satisfaction data and the second satisfaction data.

[0114] Exemplarily, compare the optimized adjusted environmental temperature situation, environmental humidity situation indicated by the first satisfaction data and the optimized adjusted ashing path situation indicated by the second satisfaction data with the environmental temperature, environmental humidity, and ashing path during ashing the area to be ashed indicated by the ashing environment data to obtain a satisfaction instruction or a non-satisfaction instruction. If a satisfaction instruction is obtained, determine the satisfaction instruction as the ashing data. If a non-satisfaction instruction is obtained, obtain an error message for sending a reminder message. The satisfaction instruction is generated when the optimized adjusted environmental temperature situation, environmental humidity situation indicated by the first satisfaction data and the optimized adjusted ashing path situation indicated by the second satisfaction data conform to the environmental temperature, environmental humidity, and ashing path during ashing the area to be ashed indicated by the ashing environment data; the non-satisfaction instruction means that the optimized adjusted environmental temperature situation, environmental humidity situation indicated by the first satisfaction data and the optimized adjusted ashing path situation indicated by the second satisfaction data still do not conform to the environmental temperature, environmental humidity, and ashing path during ashing the area to be ashed indicated by the ashing environment data.

[0115] With such a setting, the ashing operation can be made more accurate and efficient. By continuously iterating and optimizing the ashing data, the best ashing conditions and ashing parameters can be gradually obtained, thereby minimizing material damage, improving the ashing quality, helping to reduce energy consumption and production costs, and further enhancing the ashing efficiency and effect.

[0116] In a possible implementation, the method further includes: if the ambient temperature, ambient humidity, and the adhesive stripping path indicated by the adhesive stripping environmental data meet standard requirements, obtaining adhesive stripping data.

[0117] It can be understood that the environmental temperature, environmental humidity and adhesive removal path indicated by the adhesive removal environmental data are all within the tolerance range of the plastic film material, and the adhesive removal data is obtained.

[0118] S400: Controlling the local adhesive removal equipment for adhesive removal in the adhesive removal area based on the adhesive removal data.

[0119] Exemplarily, when the debonding environment data indicated by the debonding data meets the requirements of the debonding operation, the local debonding equipment is controlled to perform debonding on the area to be debonded on the debonding device according to the debonding path and the network cable debonding method.

[0120] According to steps S100 to S400, the following effects can be achieved: by obtaining the area to be debonded on the label, the area to be debonded can be determined; by obtaining debonding environment data in real time, debonding analysis is performed on the debonding environment data to obtain debonding data; and based on the debonding data, the local debonding equipment of the label is controlled to debond the area to be debonded. This helps to perform debonding operations under optimal debonding environment conditions, dynamically adjusts the debonding process, ensures consistent debonding effects for each operation, and is not affected by changes in the external environment. Potential problems can be identified in advance to determine whether the current environment is suitable for debonding operations, and predicts changes in debonding effects in the current environment, allowing operators to make timely adjustments, reduce the occurrence of unexpected situations, thereby avoiding failures caused by unsuitable environments, reducing raw material waste and production costs. The debonding process can be automated, and it also helps to provide a precise operation path, laying the foundation for subsequent work, reducing manual intervention and human operational errors, effectively avoiding the situation where residual glue is left on the packaging bag due to the debonding process, and avoiding as much as possible the problems of difficulty in re-sticking and easy deformation of the label, thereby improving product quality and the safety and reliability of use.

For example, for plastic lamination, a carbon dioxide laser can effectively remove the glue and cause less damage to the lamination. The beam transmission system is composed of a reflecting mirror, a focusing lens, etc., and is responsible for transmitting and focusing the laser beam generated by the laser generator to the designated debonding position of the lamination. The reflecting mirror is used to change the propagation direction of the laser beam, and the focusing lens can focus the laser beam into an extremely small spot, improving the energy density and enhancing the debonding effect.
