[0030] Example 1

[0031] Figure 1 A flowchart of a method for packaging a battery shell and cover is provided for the first embodiment of the present application. The embodiment of the present application is applicable to the case of packaging the upper cover and lower shell of a battery. The method can be performed by a packaging device for a battery shell and cover. The packaging device for a battery shell and cover can be implemented in the form of hardware and / or software. The packaging device for a battery shell and cover can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0032] S110 , calculating a size deviation parameter of the second assembly component according to a deviation between an actual measured size of the second assembly component of the battery and a standard size, and a half tolerance of the second assembly component.

[0033] In the embodiments of the present application, the assembly is a component of the battery, and each assembly needs to be packaged together, for example, each assembly needs to be packaged in a packaging box. The assembly includes but is not limited to: an upper cover and a lower shell. The battery in the embodiments of the present application includes a first assembly and a second assembly. It should be noted that, taking the assembly as the upper cover and the lower shell as an example, if the first assembly is the upper cover, then the second assembly is the lower shell; if the first assembly is the lower shell, then the second assembly is the upper cover. The actual measured dimensions are the results obtained by actual testing of the second assembly, which may include the actual measured dimensions of the length and the actual measured dimensions of the width. Standard dimensions and tolerances limit the qualified size range of the second assembly, which are usually the production standards and quality inspection standards of the second assembly. It should be noted that if the actual measured dimensions are within the tolerance range of the standard dimensions, the product is qualified; if the actual measured dimensions are not within the tolerance range of the standard dimensions, the product is unqualified, that is, the product is NG.

[0034] Specifically, on the packaging production line, the actual measured dimensions of multiple second assemblies can be obtained. The actual measured dimensions may include parameters such as length and width. For each second assembly, the difference between the actual measured dimension and the standard dimension is calculated to obtain a deviation calculation result. In this case, the closer the calculated deviation is to 0, the closer the dimension of the second assembly is to the standard dimension, and the further the deviation is from 0, the further the dimension of the second assembly is from the standard dimension. Combined with the deviation and the semi-tolerance of the second assembly, a dimensional deviation parameter reflecting the degree of deviation of the dimension of the second assembly from the standard dimension can be obtained. The larger the dimensional deviation parameter, the closer the second assembly is to the standard dimension.

[0035] S120 , determining a dimensional matching degree between the first assembly and the second assembly based on a first position parameter of the first assembly in the first tolerance zone and a second position parameter of the second assembly in the second tolerance zone.

[0036] The tolerance range of the first assembly constitutes a first tolerance zone, i.e., the upper limit of the first tolerance zone is the upper tolerance limit of the first assembly, and the lower limit of the first tolerance zone is the lower tolerance limit of the first assembly. Similarly, the tolerance range of the second assembly constitutes a second tolerance zone. The first position parameter can reflect whether the actual measured dimension of the first assembly is closer to the upper tolerance limit, the median value of the tolerance, or the lower tolerance limit; similarly, the second position parameter can reflect whether the actual measured dimension of the second assembly is closer to the upper tolerance limit, the median value of the tolerance, or the lower tolerance limit. In this case, if the first position parameter reflects that the actual measured dimension of the first assembly is close to the upper tolerance limit, and the second position parameter reflects that the actual measured dimension of the second assembly is close to the upper tolerance limit, then the two assemblies are more closely matched, and the degree of dimensional matching is greater.

[0037] If the first position parameter reflects the actual measured dimension of the first assembly close to the upper tolerance limit, and the second position parameter reflects the actual measured dimension of the second assembly close to the lower tolerance limit, then one of the two assemblies is larger than the other. In this case, the two assemblies do not fully match, and the determined dimensional match is low. Therefore, the closer the first position parameter is to the second position parameter, the greater the dimensional match.

[0038] S130, determining a target second assembly that matches the target first assembly based on the size deviation parameter, the size matching degree, and the historical matching success rate of the first assembly and the second assembly; when packaging the first assembly and the second assembly, placing the target first assembly and the target second assembly correspondingly so that the two assemblies are packaged on the same battery.

[0039] Among them, the historical matching success rate of the first assembly and the second assembly reflects the probability of successful matching between the two assemblies in the past. For example, if the first assembly determines that the second assembly matches it, then the current matching is recorded as successful. If the first assembly is not within the tolerance range or the second assembly is not within the tolerance range, then the current matching failure is recorded. The historical matching success rate of the first assembly and the second assembly can be obtained by dividing the number of previous successful matches by the total number of matches.

[0040] Specifically, after obtaining the size deviation parameter, size matching degree and historical matching success rate of the first assembly and the second assembly, the target first assembly is taken as the first assembly to be matched, and each second assembly is traversed, and a target second assembly that matches the target first assembly is determined from each second assembly. Then, when packaging the target first assembly and the target second assembly, the two are placed correspondingly. In this case, the actual sizes of the target first assembly and the target second assembly are relatively matched, so that in the subsequent process stages such as battery packaging, the target first assembly and the target second assembly can be packaged together, thereby ensuring the size yield of the battery product and improving the quality of the battery product.

[0041] The technical solution of an embodiment of the present application includes: calculating a dimensional deviation parameter of a second assembly of a battery based on a deviation between the actual measured dimension and the standard dimension, and a half-tolerance of the second assembly; determining a dimensional matching degree between the first assembly and the second assembly based on a first position parameter of the first assembly within a first tolerance zone and a second position parameter of the second assembly within a second tolerance zone; the closer the first position parameter and the second position parameter, the greater the dimensional matching degree; determining a target second assembly that matches the target first assembly based on the dimensional deviation parameter, the dimensional matching degree, and a historical matching success rate between the first and second assemblies; and placing the target first assembly and the target second assembly in correspondence with each other when packaging the first and second assemblies so that the two assemblies are packaged on the same battery. This technical solution calculates a target second assembly that matches the target first assembly based on the dimensional deviation parameter, the dimensional matching degree, and the historical matching success rate. When packaging the first and second assemblies, the target first assembly and the target second assembly with a closer actual dimension match are packaged in correspondence, thereby improving the yield rate of the battery packaging stage.

[0042] Example 2

[0043] Figure 2 This is a flow chart of a method for packaging a battery shell and cover provided in Example 2 of the present application. This embodiment of the present application is optimized based on the above embodiment.

[0044] like Figure 2 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0045] S210 , calculating a size deviation parameter of the second assembly component according to a deviation between an actual measured size of the second assembly component of the battery and a standard size, and a half tolerance of the second assembly component.

[0046] In an embodiment of the present application, optionally, calculating a size deviation parameter of the second assembly of the battery according to a deviation between an actual measured size of the second assembly and a standard size, and a half tolerance of the second assembly, includes determining the size deviation parameter according to the following formula:

[0047]

[0048] Wherein, SMS is the dimensional deviation parameter, Δd is the deviation between the actual measured size of the second assembly and the standard size. It should be noted that |Δd| is the absolute value of Δd; T / 2 is the half tolerance of the second assembly.

[0049] For example, if the second assembly is a top cover, its actual measured length is 12.2, the standard length is 12.0, and the length tolerance is 12.0 ± 0.5. In this case, the tolerance is 1.0 and the half tolerance is 0.5. Subtract the standard length from the actual measured length of the second assembly to obtain the deviation between the actual measured length and the standard length of the second assembly, that is, 12.2 - 12.0 = 0.2. The SMS of the length is then calculated to be 5 / 7. It should be noted that the calculation method for width is similar. In this case, the length and width dimensional deviation parameters can be obtained. The superposition of the two can be normalized to the range of 0-1 to obtain the final dimensional deviation parameter.

[0050] This solution is configured such that the greater the deviation between the actual measured size of the second assembly and the standard size, the smaller the calculated size deviation parameter, and the smaller the deviation between the actual measured size of the second assembly and the standard size, the larger the calculated size deviation parameter. The degree of standardization of the size of the second assembly can be judged based on the size of the size deviation parameter.

[0051] S220: Subtract the second position parameter from the first position parameter to obtain a third difference.

[0052] In an embodiment of the present application, optionally, the calculation process of the first position parameter includes: subtracting the first tolerance lower limit from the actual measured size of the first assembly to obtain a first difference; and determining the ratio of the first difference to the first tolerance bandwidth as the first position parameter.

[0053] For example, taking length as an example, if the actual measured length is 14.2, the standard length is 14.0, and the tolerance range of the length is 14.0±0.5, in this case, the actual measured length of the first assembly is subtracted from the first tolerance lower limit, and the first difference is 0.7; the ratio of the first difference to the first tolerance bandwidth (1.0) is determined as the first position parameter, and the first position parameter is 0.7.

[0054] The calculation process of the second position parameter includes: subtracting the second tolerance lower limit from the actual measured size of the second assembly to obtain a second difference; and determining the ratio of the second difference to the second tolerance bandwidth as the second position parameter.

[0055] For example, if the second assembly is an upper cover plate, the actual measured length is 12.2, the standard length is 12.0, and the length tolerance range is 12.0±0.4. In this case, the actual measured length of the second assembly is subtracted from the second tolerance lower limit to obtain the second difference: 12.2-11.6=0.6; and the ratio of the second difference to the second tolerance bandwidth is determined as the second position parameter: 06 / 0.8=0.75.

[0056] Obviously, the closer the actual measured dimension is to the lower tolerance limit, the closer the calculated position parameter is to 0; the closer the actual measured dimension is to the upper tolerance limit, the closer the position parameter is to 1; and the closer the actual measured dimension is to the standard dimension, the closer the position parameter is to 0.5. In this case, the first position parameter reflects the position of the actual measured dimension of the first assembly within the first tolerance zone, and the second position parameter reflects the position of the actual measured dimension of the second assembly within the second tolerance zone. The closer the first and second position parameters are, the more closely the dimensions of the first and second assemblies match. For example, if the first position parameter is 0.12 and the second position parameter is 0.1, the dimensions of the first and second assemblies are both close to the lower tolerance limit, and the yield rate of batteries packaged with the first and second assemblies is higher.

[0057] S230 , determining a size matching degree according to an absolute value of the third difference; the absolute value of the third difference is inversely proportional to the size matching degree.

[0058] In the embodiment of the present application, optionally, determining the size matching degree according to the absolute value of the third difference includes: subtracting the absolute value of the third difference from a constant 1 to obtain the size matching degree.

[0059] Exemplarily, after calculating the third difference, the absolute value of the third difference is calculated, and the absolute value is subtracted from a constant 1, that is, 1-|third difference|, to obtain the size matching degree.

[0060] It should be noted that since the size matching degree may be the size matching degree of length, the size matching degree of width, etc., these size matching degrees of length and width can be superimposed and then normalized to obtain the final size matching degree between the calculation result positions 0-1.

[0061] This solution is configured such that the greater the calculated size matching degree, the more closely the sizes of the first assembly and the second assembly are matched.

[0062] S240 , determining a target second assembly that matches the target first assembly according to the size deviation parameter, the size matching degree, and the historical matching success rate of the first assembly and the second assembly.

[0063] In an embodiment of the present application, optionally, determining a target second assembly that matches the target first assembly based on the size deviation parameter, the size matching degree, and the historical matching success rate of the first assembly and the second assembly includes: calculating a comprehensive evaluation score of the target first assembly and each second assembly based on the size deviation parameter, the size matching degree, and the historical matching success rate of the first assembly and the second assembly; and determining the second assembly corresponding to the largest comprehensive evaluation score among the comprehensive evaluation scores as the target second assembly.

[0064] The process of determining the comprehensive evaluation scores of the first assembly and the second assembly includes: determining a first weight corresponding to the size deviation parameter, a second weight corresponding to the size matching degree, and a third weight corresponding to the historical matching success rate; and superimposing the product of the first weight and the size deviation parameter, the product of the second weight and the size matching degree, and the product of the third weight and the historical matching success rate to obtain a comprehensive evaluation score.

[0065] For example, the sum of the first, second, and third weights is 1. The first weight can be represented by α, the second weight can be represented by γ, and the third weight can be represented by β, i.e., α + β + γ = 1. The specific values ​​of the first, second, and third weights can be set according to actual circumstances. For example, when there is less historical data, the third weight corresponding to the historical matching success rate can be smaller than the first or second weight. As the historical data increases, the third weight corresponding to the historical matching success rate can be appropriately increased.

[0066] This solution is configured such that the weights of the size deviation parameter, size matching degree, and historical matching success rate of the first assembly and the second assembly when calculating the comprehensive evaluation score can be flexibly adjusted, so that the calculation result of the comprehensive evaluation score is more in line with the actual situation.

[0067] In this technical solution, the more consistent the positions of the first assembly and the second assembly on their respective tolerance zones, the greater the dimensional matching degree. For example, if the first assembly is close to the upper tolerance limit and the second assembly is also close to the upper tolerance limit, the dimensional matching degree is greater; if the first assembly is close to the lower tolerance limit and the second assembly is close to the upper tolerance limit, the dimensional matching degree is smaller. The larger the dimensional deviation parameter, the closer the second assembly is to the standard size. The greater the historical matching success rate, the easier it is for the first assembly and the second assembly of this model to be successfully matched. Obviously, the larger the three data calculated for the first assembly and the second assembly, the more matched the two assemblies are. In this case, when determining the target second assembly that matches the target first assembly, the comprehensive evaluation score of the target first assembly and each second assembly can be calculated, and the second assembly corresponding to the largest comprehensive evaluation score can be determined as the target second assembly.

[0068] S250 , sending a signal to the robot arm to package the target first assembly component and the target second assembly component accordingly, and sending the storage coordinates of the target first assembly component and the target second assembly component to the robot arm.

[0069] Specifically, the storage coordinates of the target first assembly and the target second assembly: (x_h, y_h) and (x_t, y_t) can be converted into the robot coordinate system (x_robot, y_robot), so that the robot moves to a safe upper height of the target first assembly and the target second assembly, vertically grasps the target first assembly and the target second assembly and places them in the corresponding packaging positions of the target first assembly and the target second assembly.

[0070] In a specific example, the first assembly part is the upper cover plate, and the second assembly part is the lower shell. When packaging the upper cover plate and the lower shell, the matching lower shell H and upper cover plate T determined through the above steps can be used: (H1-T1, H2-T2...) to indicate that each pair of lower shell H and upper cover plate T are arranged side by side and placed in the contoured foam. In the packaging box, multiple layers of contoured foam are arranged, and each contoured foam is isolated by a partition with concave and convex limiting features.

[0071] Figure 3 A schematic diagram of a packing box. Figure 4 This is a schematic diagram of a contoured foam. A corresponding lower shell placement position and an upper cover placement position are set in the contoured foam so that the lower shell and the upper cover can be placed correspondingly. Figure 5 A schematic diagram of the placement of the lower shell and the upper cover is shown in FIG. Figure 5 In the embodiment, the lower shell can be placed in the lower shell placement position of the contoured foam. Next to each lower shell placement position, a corresponding upper cover placement position is provided for placing an upper cover matching the lower shell.

[0072] In the embodiments of the present application, the integrated contoured foam can be arranged in any arrangement, front-to-back, and left-to-right, between the lower shell and upper cover, with spacing provided between them to accommodate size differences and allow for repeated side-by-side placement. When placing the lower shell and upper cover, after the first layer (bottom layer) is placed, a concave and convex spacer is placed on top (between the first and second layers) to secure the first layer and allow the second layer of products to be placed. After the first layer is placed, the second layer is arranged in the same manner, and N layers (N is determined by the height of the box) are placed in sequence.

[0073] The technical solution of the embodiment of the present application calculates the comprehensive evaluation scores of the target first assembly and each second assembly using three dimensions: dimensional deviation parameter, dimensional matching degree, and historical matching success rate. The second assembly with the highest comprehensive evaluation score is then determined as the target second assembly, resulting in a matching target first assembly and target second assembly. When packaging the first and second assemblies, the target first and second assemblies are then placed in correspondence, allowing them to be packaged into the same battery. Because the first and second assemblies of the battery are closely matched, the battery packaging yield is improved.

[0074] In a specific example, α, β, and γ are assigned according to business requirements (for example, α = 0.5, β = 0.3, and γ = 0.2). For each candidate product (taking the lower shell corresponding to a target upper cover as an example, each lower shell is a candidate product), a comprehensive evaluation score TS of each candidate product and the target upper cover is calculated:

[0075] TS = α*size deviation parameter + β*historical matching success rate + γ*size matching degree.

[0076] Select the candidate product with the highest TS.

[0077] Example: Assume there are two candidate products (the candidate products may be upper cover or lower shell):

[0078]

[0079] Weight distribution: α: 0.5, β: 0.3, γ: 0.2.

[0080] Calculation: TS of Product A:

[0081] TS=0.5*0.8+0.3*0.9+0.2*0.7=0.4;

[0082] TS of Product B:

[0083] TS=0.5*0.9+0.3*0.8+0.2*0.6=0.45;

[0084] If the TS values ​​are the same, one of the products can be selected for matching packaging, or the scoring details can be optimized or the weights can be adjusted. If the TS values ​​are different, the product with the highest TS value can be selected for matching packaging.

The device can execute the battery shell and cover packaging method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method. Figure 6 As shown, the device includes:

[0087] a size deviation parameter determination module 310 for calculating a size deviation parameter of the second assembly of the battery according to a deviation between an actual measured size of the second assembly and a standard size, and a half tolerance of the second assembly;

This technical solution calculates the target second assembly that matches the target first assembly through three parameters: size deviation parameter, size matching degree, and historical matching success rate. When packaging the first assembly and the second assembly, the target first assembly and the target second assembly with a closer actual size match are packaged correspondingly, thereby improving the yield rate in the battery packaging stage.
