[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] It should be noted that, in the description of the embodiments of the present invention, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0030] To more clearly and fully illustrate the technical solution and corresponding technical effects provided by the present invention, a brief description of the implementation methods of the prior art is first given.

[0031] Figure 1 It is one of the schematic diagrams provided by existing technology to determine a specific vehicle type. Figure 2 This is the second schematic diagram provided by existing technology to determine a specific vehicle type. In this diagram, the project code, power type, and electric axle represent vehicle characteristics. A vehicle can include multiple vehicle characteristics.

[0032] Existing technology determines vehicle type by selecting multiple vehicle type features from all vehicle type features. For example, ... Figure 1 As shown, in the method of determining the vehicle type based on the project code and power type, a corresponding tightening tool T01 can be set to perform a tightening operation on the vehicle whose vehicle type is determined in this way: if the feature character code corresponding to the project code is AAAD3 and the feature character code corresponding to the power type is AAE55, the vehicle type of the current vehicle is determined to be A0001; for example... Figure 2 As shown, in the method of determining the vehicle type based on the project code and the electric axle, a corresponding tightening tool T02 can be set to perform a tightening operation on the vehicle whose vehicle type is determined in this way: if the feature character code corresponding to the project code is AAAD3 and the feature character code corresponding to the electric axle is CBG00, the vehicle type of the current vehicle is determined to be B0001; furthermore, after the tightening tool determines the specific vehicle type, the tightening program corresponding to the current vehicle type can be called to perform the vehicle tightening operation. In addition, the prior art can also set tool T03 to perform tightening operations for all vehicle types, such as the tire tightening operation that needs to be performed for all vehicle types.

[0033] Analysis shows that due to the numerous vehicle model characteristics, there are many ways to determine the vehicle type based on different model characteristics; furthermore, under the same method of determining the vehicle type, there are also many specific vehicle types, resulting in a wide variety of vehicle types, which is not conducive to the setting and maintenance management of the tightening program.

[0034] Based on this, the present invention designs a tightening method and device applied in the vehicle assembly process, which is described below in conjunction with... Figures 3-5 This invention describes a tightening method and apparatus for use in vehicle assembly processes, as provided in embodiments of the present invention.

[0035] Figure 3 This is a flowchart illustrating the tightening method applied in the vehicle assembly process provided by the present invention, as shown below. Figure 1 As shown, including but not limited to the following steps:

[0036] Step 301: Control the current tightening tool to obtain the vehicle type identification code of the current vehicle.

[0037] The vehicle type identification code can be obtained using a barcode scanning device. The barcode scanning device can be set up separately or integrated into the tightening tool. The current vehicle can be a car or other types of vehicles.

[0038] As an optional embodiment, controlling the current tightening tool to obtain the vehicle type identification code of the current vehicle, i.e., step 301 specifically includes:

[0039] (1) Use a barcode scanner to read the vehicle identification code of the current vehicle to obtain the feature character code corresponding to each model feature of the current vehicle.

[0040] The vehicle model features correspond one-to-one with the feature character codes. The types of vehicle model features include, but are not limited to, project codes, powertrain types, and electric axles. For example, if the current vehicle has N1 vehicle model features, then it corresponds to N1 feature character codes; the feature character codes can be strings, such as AAAD3.

[0041] (2) Based on the encoding of each feature character, the vehicle type identification code of the current vehicle is formed.

[0042] Arranging each feature character code in a preset order can form a longer string, which is the vehicle type identification code.

[0043] (3) The current tightening tool receives the vehicle type identification code sent by the scanning device to obtain the vehicle type identification code.

[0044] The barcode scanner is connected to the current tightening tool. Once the scanner obtains the vehicle type identification code of the current vehicle, it can send it to all tightening tools at the current workstation.

[0045] Step 302: Match the target wildcard matching rule that matches the vehicle type identification code from the wildcard matching rule set of the current tightening tool.

[0046] It is understandable that different wildcard matching rule sets are set for different tightening tools, and there is a one-to-one correspondence between wildcard matching rule sets and tightening tools; each wildcard matching rule set includes multiple pre-set wildcard matching rules, and the wildcard matching rules are also set in a one-to-one correspondence with vehicle types. The vehicle type also corresponds one-to-one with the tightening operation performed.

[0047] Optionally, if the target wildcard matching rule matching the vehicle type identification code cannot be matched from the wildcard matching rule set of the current tightening tool, the next tightening tool can be used for rematching.

[0048] Optionally, the next tool includes a tool for tightening operations on universal vehicle models, wherein the wildcard matching rules of the tool are set to match all vehicle type identification codes to perform universal tightening operations on universal vehicle models (all vehicle types), such as tightening operations on tire components.

[0049] Step 303: Determine the target vehicle type of the current vehicle according to the target wildcard matching rules.

[0050] Step 304: Based on the target vehicle type, control the current tightening tool to perform a tightening operation on the current vehicle.

[0051] The tightening method provided by this invention, applicable to vehicle assembly processes, pre-sets corresponding wildcard matching rule sets for different tightening tools. Then, using vehicle type identification codes, it determines the target vehicle type corresponding to the target wildcard matching rule from the current tightening tool's wildcard matching rule set, and invokes the corresponding tightening process to achieve the vehicle tightening operation. This invention, by setting corresponding vehicle types through wildcard matching rules, significantly reduces the number of vehicle types and supports the expansion of more vehicle model features, making the setting and maintenance management of tightening programs more convenient.

[0052] Based on the above embodiments, as an optional embodiment, the tightening method of the present invention applicable to the vehicle assembly process, when the wildcard matching rule set is configured in a first mode, the step of determining the target vehicle type of the current vehicle according to the target wildcard matching rule includes: taking the vehicle type corresponding to the unique target wildcard matching rule as the target vehicle type.

[0053] Specifically, the first mode is: there is one and only one target wildcard matching rule that matches the vehicle type identification code from the wildcard matching rule set.

[0054] Based on the above embodiments, as an optional embodiment, the tightening method of the present invention applicable to the vehicle assembly process, when the wildcard matching rule set is configured in the second mode, the step of determining the target vehicle type of the current vehicle according to the target wildcard matching rule includes: when there is only one target wildcard matching rule, taking the vehicle type corresponding to the current target wildcard matching rule as the target vehicle type; when there are multiple target wildcard matching rules, determining the target vehicle type according to the priority value corresponding to each target wildcard matching rule.

[0055] Specifically, the second mode is as follows: there is at least one target wildcard matching rule in the wildcard matching rule set that matches the vehicle type identification code, wherein the priority value is set in a one-to-one correspondence with the wildcard matching rule, and the priority values ​​corresponding to different target wildcard matching rules are different.

[0056] It should be noted that the first and second modes mentioned above refer to the setup under the premise that there exists a target wildcard matching rule in the current tightening tool's wildcard matching rule set that matches the vehicle type identification code. Based on the above embodiments, as an optional embodiment, determining the target vehicle type according to the priority value corresponding to each target wildcard matching rule includes: selecting the target wildcard matching rule with the highest priority value as the final target wildcard matching rule; and using the vehicle type corresponding to the final target wildcard matching rule as the target vehicle type.

[0057] Specifically, Figure 4 This is a schematic diagram illustrating the method for determining the target vehicle type provided by the present invention, as shown below. Figure 4 As shown, using * as a wildcard simplifies the way vehicle types are determined and reduces the number of vehicle types, resulting in a geometric reduction in the number of tightening processes.

[0058] like Figure 4 As shown, by utilizing the pre-configured wildcard matching rule set of the current tightening tool T01, the target vehicle type can be matched based on the vehicle type identification code composed of feature character codes of vehicle characteristics such as vehicle model matching item code and power type. When there are more than two matching results, the one with the higher priority value is selected. Those skilled in the art can verify the priority value to avoid situations where the priority values ​​are the same when there are two or more matching results.

[0059] For example, the vehicle types matched by the wildcard matching rule based on sequence number 1 include those matched by the wildcard matching rule based on sequence number 6, but their corresponding priority values ​​are different. Furthermore, it's understandable that the priority values ​​are set based on the actual situation to ensure the tightening operation can be performed correctly. Figure 4 In the example, the priority value of the wildcard matching rule corresponding to sequence number 1 is 1, and the priority value of the wildcard matching rule corresponding to sequence number 6 is 2. When a certain vehicle type identification code matches the wildcard matching rules corresponding to sequence number 1 and sequence number 6 at the same time, since the priority value of the wildcard matching rule corresponding to sequence number 6 is the highest, the final determined target vehicle type is D0006.

[0060] As we know, wildcard matching rules are a commonly used matching method in computer programming. They help technicians quickly match strings that conform to specific rules. Wildcard matching rules are a type of string matching rule based on wildcard symbols.

[0061] Optionally, the wildcard symbol "*" in this invention is a special character that can represent any character (mainly letters and numbers in this invention). Based on this, matching of specific strings can be achieved. For example, ***** can represent all strings of length 5, and CBG** means matching strings of length 5 that start with CBG.

[0062] Optionally, the length of the wildcard matching rule in this invention can be the same as the length of the vehicle type identification code.

[0063] Based on the above principle, this invention addresses the tightening tool T03, which requires tightening operations on all vehicle types. It only requires setting a wildcard matching rule: ***…*** (all as *, with the same length as the vehicle type identification code) to configure all vehicle types (general models), and then setting the corresponding tightening process parameter information.

[0064] Based on the above embodiments, as an optional embodiment, the tightening method applied in the vehicle assembly process provided by the present invention includes: determining tightening process parameter information corresponding to the current vehicle according to the target vehicle type; and controlling the current tightening tool to perform a tightening operation on the current vehicle according to the tightening process parameter information.

[0065] The technical solution of this invention can be implemented through a database, such as configuring parameters like the wildcard matching rule set for the current tightening tool, vehicle type, and corresponding tightening process parameters in the database. After the current tightening tool obtains the vehicle type of the current vehicle, it can use the method described above to retrieve the required tightening process parameters from the pre-set database, and then perform the tightening operation according to the tightening process parameters.

[0066] The tightening process parameters correspond one-to-one with the vehicle type and are used to perform the corresponding tightening operations, including but not limited to the tightening program and target tightening torque used to perform the tightening operations.

[0067] It should be noted that, regardless of the specific implementation method of the present invention, as long as it is substantially the same as the method of the present invention, it is within the protection scope of the present invention, and will not be elaborated here.
