Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of an identification code verification method according to a first embodiment of the present invention. The identification code inspection method provided by the invention comprises the following steps:
s101: and scanning the label of the object to be detected to obtain a first digital identification code and an image identification code.
In a specific implementation scene, a label is attached to an object to be detected for marking, so that the follow-up process tracking is facilitated, and the label comprises a first digital identification code and an image identification code. The content represented by the image identification code and the content represented by the first digital identification code are at least partially repeated, so that the content obtained by analyzing the image identification code should be partially identical to the content of the first digital identification code. If not, it is possible that the first numeric identification code has portions of the content that are incorrect. Therefore, the contents of the first digital identification code and the image identification code need to be compared.
In this implementation scenario, the object to be inspected is a display panel to be processed in the display panel manufacturing process. In other embodiments, the object to be examined can also be any semi-finished product in the production process.
In the implementation scenario, the machine scans the label of the object to be inspected to obtain the first digital identification code and the image identification code on the label. In other implementation scenarios, a picture of the tag can be obtained by a photographing method, and the first digital identification code and the image identification code in the picture can be obtained by an image processing method.
In this implementation scenario, please refer to fig. 2 in combination, and fig. 2 is a schematic diagram of an embodiment of a tag in the identification code verification method provided by the present invention. As shown in fig. 2, the first numeric identification code 10 in the tag includes a first serial code 11 and a second serial code 12. In this implementation scenario, the last two digits of the first digital identification code 10 are the second serial code 12, and in other implementation scenarios, the digits of the first serial code and the second serial code may be set arbitrarily according to actual use conditions. In the present implementation scenario, the first digital identification code is a Chip ID (Chip identification code), the first serial code 11 is a GLASS ID (GLASS identification code), and the second serial code is a Chip No (Chip serial code).
In this embodiment, the first serial code 11 is divided into two parts and located on both sides of the image identification code, but in other embodiments, the first serial code 11 may be located on only one side of the image identification code.
S102: and decoding the image identification code to obtain a second digital identification code, and receiving a third digital identification code sent by the computer.
In a specific implementation scenario, after obtaining the image identification code, the machine decodes the image identification code to obtain the content represented by the image identification code. With continued reference to fig. 2, the image id is the content of the oval circle in fig. 2. In the present implementation scenario, the image identification code is a two-dimensional code as shown in fig. 2. In other implementations, the image identification code may also be a barcode, or a combination of two-dimensional codes and barcodes.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a result of decoding an image identifier in the identifier verification method according to the present invention. As shown in fig. 3, decoding the image identification code will result in a plurality of contents, and extracting the second numeric identification code from the decoded contents. In this implementation, the second digital ID is decoded from the gla file, and the name character of the grayscale image is truncated for the fixed point containing the Panel ID.
In other implementations, the second digital ID can also be found from the information contained in the gla file according to a predetermined algorithm. For example, in order to obtain the second numeric identification code quickly, a key character may be set, for example, in this implementation scenario, the key character is "Panel", and after the image identification code is decoded, the number after the character "Panel" is found from the gla file, and the number after the Panel "is the second numeric identification code.
In this implementation scenario, a third digital identification code obtained by the computer is also received, where the third digital identification code may be pre-stored by the computer, or obtained by other means.
S103: and combining the second digital identification code and the third digital identification code to obtain a combined identification code, and judging whether the combined identification code is matched with the first digital identification code. If yes, go to step S104.
In a specific implementation scenario, the second numeric identification code and the third numeric identification code obtained in step S102 are combined to obtain a combined identification code. In this embodiment, the second numeric identification code and the third numeric identification code are combined in a predetermined order, for example, the third numeric identification code is before and the second numeric identification code is after. The second numeric identification code and the third numeric identification code may also be randomly arranged in other implementation scenarios.
And comparing the obtained combined identification code with the first digital identification code to judge whether the combined identification code is matched with the first digital identification code. In this implementation scenario, the third digital identification code obtained by the computer is the first serial code, and the second digital identification code obtained by decoding the image identification code is the second serial code, so that after the third digital identification code and the second digital identification code are arranged in a specific order, the combined identification code obtained by the third digital identification code and the second digital identification code should be the same as the first digital identification code. Therefore, the combined identification code and the first digital identification code can be compared bit by bit, and if the combined identification code and the first digital identification code are the same, the combined identification code and the first digital identification code are matched. If at least one bit is different, there is no match.
In other implementation scenarios, the third numeric identification code may be compared with the first sequence code, the second numeric identification code may be compared with the second sequence code, if both comparison results are matched, a match is determined, and if one comparison result is not matched, a mismatch is determined.
S104: the object to be detected is determined to correspond to the label.
In a specific implementation scenario, if the combined identification code is determined to match the first digital identification code, it is determined that the object to be detected corresponds to the tag. The object to be inspected passes the inspection and the next process can be continued.
In other implementation scenarios, if it is also possible that the combined identification code does not match the first digital identification code, it is determined that the object to be detected does not correspond to the tag, and therefore the object to be detected is retained, and the next procedure is not performed, but is retained for processing, for example, the tag is changed.
As can be seen from the above description, in the embodiment, the second identification code is obtained by decoding the image identification code, the third identification code sent by the computer is received, and the second identification code and the third identification code are combined and then compared with the first digital identification code on the label to determine whether the object to be detected corresponds to the label, so that all the digits of the first digital identification code can be completely checked, and the accuracy of the identification code check can be effectively improved.
