Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] Figure 1 This is a schematic flowchart of a colloidal coating method provided in an embodiment of the present disclosure.

[0039] like Figure 1 As shown, the colloidal coating method includes the following steps:

[0040] S101, Obtain the thickness of the first layer of colloid that has been coated and the target coating information of the colloid coating.

[0041] It should be noted that this application does not limit the material of the colloid, and it can be selected according to the actual situation. Optionally, the colloid can be silver paste.

[0042] In this embodiment of the disclosure, the thickness of the first layer of colloid on the coated terminal can be collected to obtain the thickness of the first layer of colloid on the terminal.

[0043] It should be noted that the specific method for collecting the thickness of the first layer of colloid in this disclosure is not limited, and can be obtained according to the actual situation.

[0044] Optionally, line structured light can be introduced into the production line to collect the thickness of the first layer of colloid.

[0045] It should be noted that the target coating information for colloidal coating can be the total colloidal thickness of the terminal.

[0046] S102, if the thickness of the first layer of colloid is within the preset thickness range, the target amount of colloid to be coated for the second layer of colloid is determined by a mapping function based on the thickness of the first layer of colloid and the target coating information. The mapping function is determined by historical coating data and coating parameters.

[0047] In this embodiment of the application, if the thickness of the first layer of colloid is not within the preset thickness range, the second layer of colloid coating on the terminal is stopped.

[0048] It should be noted that this application does not limit the preset thickness range, which can be set according to the actual situation.

[0049] It should be noted that when attempting to determine the target amount of adhesive to be applied for the second layer of colloid, the target amount of adhesive to be applied for the second layer of colloid can be determined by calculating the thickness of the first layer of colloid and the target coating information based on the mapping function.

[0050] It should be noted that this application does not limit the specific method for obtaining the mapping function, and it can be selected according to the actual situation.

[0051] Optionally, in constructing the initial polynomial of the mapping function, the mapping function is determined by using historical coating data and coating parameters, and the initial polynomial of the mapping function is fitted to determine the final mapping function.

[0052] S103, based on the target adhesive output, apply a second layer of adhesive to the terminal.

[0053] In this embodiment of the disclosure, after obtaining the target amount of adhesive, the terminal can be coated with the second layer of adhesive according to the target amount of adhesive required for coating the second layer of adhesive.

[0054] According to an embodiment of this disclosure, a method for applying an adhesive layer involves acquiring the thickness of a first layer of adhesive and target coating information. If the thickness of the first layer is within a preset range, a target amount of adhesive to be applied for a second layer is determined using a mapping function based on the thickness of the first layer and the target coating information. The mapping function is determined using historical coating data and coating parameters. The second layer of adhesive is then applied to the terminal based on the target amount of adhesive. Therefore, this disclosure accurately determines the target amount of adhesive to be applied for the second layer by using the thickness of the first layer, the target coating information, and the mapping function, improving process accuracy and yield, reducing costs in the adhesive coating process, and enhancing the quality of the final product.

[0055] Figure 2 This is a schematic flowchart of a colloidal coating method according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 2 The specific process of determining the mapping function using sample data and sample coating information is explained, including the following steps:

[0056] S201, collect the total colloid thickness and the first layer colloid thickness of the sample terminal as historical coating data.

[0057] The total colloid thickness of the sample terminal is the sum of the thickness of the first colloid layer and the thickness of the second colloid layer of the sample terminal.

[0058] It should be noted that this disclosure does not impose any limitation on the total colloid thickness setting of the sample terminal, and it can be selected according to the actual situation.

[0059] Optionally, the total colloid thickness of the sample terminal can be set according to the control values ​​of different process lines.

[0060] For example, the total colloid thickness of the sample terminal can be set to 0.2 mm.

[0061] It should be noted that the specific method for collecting the thickness of the first layer of colloid at the sample terminal is not limited in this disclosure, and can be obtained according to the actual situation.

[0062] Optionally, line structured light can be introduced into the production line to collect the thickness of the first layer of colloid at the sample terminal.

[0063] It should be noted that before collecting the total colloid thickness and the thickness of the first colloid layer at the sample terminal, the accuracy of the length and width of the first colloid layer also needs to be monitored.

[0064] It should be noted that this disclosure does not limit the specific method for obtaining the length and width of the first layer of colloid, and the method can be determined according to the actual situation.

[0065] Optionally, a CCD camera can be introduced into the production line to obtain images corresponding to the length and width of the first layer of colloid, and the length and width of the first layer of colloid can be obtained based on the images.

[0066] It should be noted that, since there are precision requirements for the length and width of the first layer of colloid on the production line, if the precision of the length and width of the first layer of colloid does not meet the target precision, a new sample terminal is selected. If the precision of the length and width of the first layer of colloid meets the target precision, the total colloid thickness and the thickness of the first layer of colloid of that sample terminal are directly collected.

[0067] It should be noted that this application does not impose any limitations on the setting of target accuracy, which can be set according to the actual situation.

[0068] It should be noted that since the length and width of the second layer of colloid are usually smaller than those of the first layer, if the accuracy of the length and width of the first layer of colloid meets the target accuracy, then the accuracy of the length and width of the second layer of colloid will also meet the target accuracy.

[0069] S202, determine the mapping function based on historical coating data and the coating parameters of the sample terminal coated colloid.

[0070] It should be noted that the coating parameters of the sample terminal coating colloid can be the viscosity of the colloid, the coating pore size of the colloid, and the coating speed of the colloid during the coating process.

[0071] In this embodiment of the disclosure, after obtaining historical coating data and coating parameters of the sample terminal coating colloid, data verification can be performed based on the historical coating data and coating parameters of the sample terminal coating colloid to determine the mapping function.

[0072] According to an embodiment of the present disclosure, a colloidal coating method is used to collect the total colloidal thickness and the thickness of the first colloidal layer of the sample terminal as historical coating data. A mapping function is determined based on the historical coating data and the coating parameters of the colloidal coating on the sample terminal. The accuracy of the length and width of the first colloidal layer is monitored. Therefore, sample terminals that do not meet the target accuracy can be screened out, improving the quality of the terminal and laying the foundation for accurately obtaining the target amount of adhesive output required for the second colloidal coating based on the mapping function.

[0073] Figure 3 This is a schematic flowchart of a colloidal coating method according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 3 The process prior to determining the mapping function based on historical coating data and the coating parameters of the sample terminal coated colloid is explained, including the following steps:

[0074] S301, Construct the initial polynomial for the mapping function.

[0075] Alternatively, the initial polynomial of the mapping function can be constructed as follows:

[0076] Where Z is the total colloid thickness, Z1 is the thickness of the first colloid layer, K is the viscosity of the colloid, d is the coating pore size of the colloid, Q is the required amount of colloid dispensed, and V is the coating speed. ∝ is the first coefficient, and ∝ is the second coefficient.

[0077] S302, based on historical coating data and coating parameters, fit the initial polynomial to determine the final mapping function.

[0078] In this embodiment of the disclosure, after constructing the initial polynomial of the mapping function, the initial polynomial can be fitted to determine the first and second coefficients of the initial polynomial of the mapping function.

[0079] Optionally, the first and second coefficients of the initial polynomial of the mapping function can be determined based on a regression method, thereby determining the final mapping function.

[0080] Furthermore, after obtaining the final mapping function, the thickness of the first layer of colloid and the target coating information can be calculated based on the mapping function to determine the target amount of adhesive to be applied to the second layer of colloid.

[0081] It should be noted that, as can be seen from the mapping function, since the coating information of the sample terminal coated colloid is known, and the total colloid thickness is determined according to the process production line control value, the target amount of colloid required for the second layer to be coated can be determined by calculating the thickness of the first layer of colloid and the target coating information according to the mapping function.

[0082] For example, the thickness data Z0 of the first layer of colloid at the terminal is substituted into the mapping function: In the diagram, Z represents the total colloid thickness, Z0 represents the thickness of the first colloid layer, K represents the viscosity of the colloid, d represents the colloid coating aperture, Q represents the target amount of colloid to be applied for the second colloid layer, and V represents the coating speed. ∝ represents the first coefficient, and ∝ represents the second coefficient. Wherein, the total colloid thickness Z is the process line control value, the first layer colloid thickness Z0, the colloid viscosity K, the colloid coating aperture d, the coating speed V, and the first coefficient are... If the second coefficient ∝ is known, then the thickness of the first layer of colloid and the target coating information can be calculated to determine the target amount of adhesive Q required for the second layer of colloid to be coated.

[0083] Figure 4 This is a schematic flowchart of a colloidal coating method according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 4 The process of determining the target amount of adhesive to be applied for the second layer of colloid by calculating the thickness of the first layer and the target coating information based on the mapping function is explained, including the following steps:

[0084] S401, Obtain the thickness curve of the first layer of colloid in the terminal, and segment the thickness curve.

[0085] Optionally, the thickness curve of the first layer of colloid at the terminal can be obtained based on line structured light.

[0086] It should be noted that this application does not limit the number of segments for the thickness curve, and the number can be selected according to the actual situation.

[0087] Optionally, the thickness curve can be divided into five equal segments.

[0088] S402, determine the average thickness of the first layer of colloid for each segment of the thickness curve after segmentation.

[0089] It should be noted that after segmenting the thickness curve, the thickness data of the first layer of colloid in each segment can be obtained, and the average value of the thickness data of the first layer of colloid in each segment can be taken.

[0090] S403, based on the mapping function, calculate the average thickness of each segment of the first layer of colloid and the target coating information to determine the target amount of adhesive to be applied to the second layer of colloid corresponding to each segment of the first layer of colloid.

[0091] For example, the thickness curve acquired by the line structured light can be divided into five equal segments, and the average thickness of the first layer of colloid in each segment can be obtained. In this case, there are five average thicknesses of the first layer of colloid in each segment. According to the mapping function, the average thickness of the first layer of colloid in each segment and the target coating information can be calculated to determine the target amount of adhesive to be applied to the second layer of colloid corresponding to each segment of the first layer of colloid. In this case, the target amount of adhesive to be applied to the second layer of colloid corresponding to each segment of the first layer of colloid is also five.

[0092] Therefore, this disclosure proposes an colloid coating method. The method involves obtaining the thickness curve of the first colloid layer in the terminal, segmenting the thickness curve, determining the average thickness of the first colloid layer for each segment, and then calculating the target amount of adhesive for the second colloid layer corresponding to each segment based on a mapping function and the target coating information. This allows for accurate determination of the target amount of adhesive for the second colloid layer, improving the precision and yield of the colloid process, reducing costs in the colloid coating process, and enhancing the quality of the final product.

[0095] The acquisition module 110 is used to acquire the thickness of the first layer of colloid that has been coated and the target coating information of the colloid coating;

[0096] The determining module 120 is used to determine the target amount of adhesive to be applied for the second layer of adhesive by means of a mapping function, based on the thickness of the first layer of adhesive and the target coating information, if the thickness of the first layer of adhesive is within a preset thickness range. The mapping function is determined by means of historical coating data and coating parameters.

[0097] The coating module 130 is used to apply a second layer of adhesive to the terminal according to the target adhesive output.

[0098] Furthermore, the determining module 120 is also used to: collect the total colloid thickness and the first layer colloid thickness of the sample terminal as historical coating data; and determine the mapping function based on the historical coating data and the coating parameters of the colloid coated on the sample terminal.

[0099] Furthermore, the determining module 120 is also used to: obtain the length and width of the first layer of colloid in the sample terminal, and monitor the accuracy of the length and width of the first layer of colloid.

[0100] Furthermore, the determining module 120 is also used to: construct an initial polynomial of the mapping function; and fit the initial polynomial according to the historical coating data and the coating parameters to determine the final mapping function.

[0101] Furthermore, the coating parameters include: the viscosity of the colloid during the colloid coating process, the pore size of the colloid, and the coating speed of the colloid.

[0102] Furthermore, the determining module 120 is also used to: calculate the target amount of adhesive to be applied to the second layer of colloid based on the mapping function, the thickness of the first layer of colloid, and the target coating information.

[0103] Furthermore, the determining module 120 is also used to: obtain the thickness curve of the first layer of colloid of the terminal, and segment the thickness curve; determine the average value of the thickness of the first layer of colloid for each segment of the segmented thickness curve; and calculate the target amount of adhesive required for the second layer of colloid to be coated corresponding to each segment of the first layer of colloid based on the average value of the thickness data of the first layer of colloid for each segment and the target coating information according to the mapping function.

[0104] Furthermore, if the thickness of the first layer of colloid is not within the preset thickness range, the device 1000 stops applying the second layer of colloid to the terminal.

[0105] According to an embodiment of this disclosure, an adhesive coating apparatus acquires the thickness of a first coated adhesive layer and target coating information. If the thickness of the first adhesive layer is within a preset thickness range, a target adhesive yield for a second adhesive layer to be coated is determined using a mapping function based on the first adhesive layer thickness and the target coating information. The mapping function is determined using historical coating data and coating parameters. The second adhesive layer is then coated onto the terminal based on the target adhesive yield. Therefore, this disclosure, through the first adhesive layer thickness, target coating information, and mapping function, can accurately determine the target adhesive yield for the second adhesive layer, improving the accuracy and yield of the adhesive process, reducing costs in the adhesive coating process, and improving the quality of the terminal.
