[0002] The assembly process of servers and personal computers involves many processes. Only when one process is completed can the subsequent process be carried out. If a process takes time, it will affect the normal execution of the subsequent process, for example, the labeling process.

[0003] The labeling process requires the pasting of multiple labels. In the related technology, the operator usually relies on experience to identify and paste the labels. However, this labeling method is very likely to cause label pasting errors or omissions. In addition, when label pasting errors occur and need to be reworked, the labels are prone to wrinkles, dirt, etc., which makes the labeling process take too long and affects the subsequent assembly process.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] In the relevant technical summary, as the number of server machine models and configurations increases, the types of labels used by each model increase. When assembling each model, labels are prone to mis-sticking, missing labels, and other operational omissions. When replacing and reworking wrong labels, it is easy to cause problems such as wrinkles and dirt on the labels, affecting production efficiency and operation quality.

[0029] In response to the above-mentioned technical problems existing in the related technology, an embodiment of the present application provides a control method for label error prevention, which realizes the automatic pasting of the entire label by controlling the labeling machine, and prevents the occurrence of wrong pasting through multi-level identification and judgment during the pasting process, thereby reducing the probability of errors in the label pasting process, improving the efficiency of label pasting, and reducing the time consumption of the labeling process.

[0030] In addition, in the whole process of machine assembly label pasting operation control, the method realizes precise control according to material coding through the Manufacturing Execution System (MES) program, improves the original identification operation mode based on experience, and optimizes the label pasting operation process. The original operation mode cannot accurately control the label pasting, and is prone to problems such as operation omission and assembly misoperation. Now the systematic control method solves the problem of low efficiency and accuracy of manual control, improves the control accuracy of label pasting during the assembly operation, and ensures the smooth and orderly progress of the entire production assembly process. This method improves the efficiency of label pasting and reduces the low production efficiency caused by high employee mobility, unfamiliarity with the labels in the machine model, unskilled operation, large differences in machine model configuration and many labels. This method adds a system anti-fool and anti-error mechanism through the label selection state and the "Confirm" button, avoiding the problem of label pasting errors and omissions during the assembly operation. This method optimizes the material code and the image display of the specification to make the machine label pasting operation process in the production order more reasonable and accurate, and improves the accuracy of label pasting quality and efficiency control. The method uses system control and automatic labeling machine pasting operations to double-check label coding and quantity, thereby reducing the risk of manual operation.

[0031] The label error prevention control method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, a label error prevention control method provided in an embodiment of the present application may include the following steps 101 to 103: Step 101: obtain the whole machine serial number of the target device to be labeled, and obtain material information of multiple labels associated with the whole machine serial number from a production execution system.

[0033] Among them, one label corresponds to one material information; the material information includes: material code, label size information, and label image.

[0034] For example, in the embodiment of the present application, the serial number on the target device can be identified by a camera or other scanning device provided on the labeling machine to obtain the whole machine serial number of the target device. Afterwards, the material information of multiple labels related to the whole machine serial number is searched in the production execution system MES. For example, the material code of the label, the label size information of the label, the label image of the label, etc.

[0035] Exemplarily, after the material information of each label among the above-mentioned multiple labels is obtained, the pasting operation of each label can be completed based on the material information of each label.

[0036] Step 102: determine the target label that needs to be pasted currently, and control the labeling machine to obtain a label to be pasted with the same material code as that corresponding to the target label from the material area.

[0037] Exemplarily, after determining the multiple labels to be pasted, the multiple labels can be pasted in a preset pasting order or in a random order. The target label is the label that needs to be pasted at the current moment among the multiple labels.

[0038] It should be noted that each of the above-mentioned multiple labels can be pasted according to the label error prevention control method provided in the embodiment of the present application.

[0039] For example, in a production workshop, all labels that need to be pasted are placed in the material area, and labels with different material codes are stored in different containers, and each container stores multiple labels. When a label corresponding to a material code needs to be pasted, the labeling machine can be controlled to find the corresponding container from the material area according to the material code, and a label is clamped from the container and pasted to the position specified by the target device.

[0040] It should be noted that in the embodiment of the present application, the label pasting position has been determined during the product design stage, and the labeling machine can paste the corresponding label to the position indicated by the pasting position information according to the pasting position information indicated by the production process information.

[0041] It is understandable that after determining the target label to be pasted and controlling the labeling machine to obtain the label to be pasted corresponding to the material code of the target label from the material area, it is necessary to determine whether the label to be pasted is the target label to be pasted. In the related art, the label image of the label to be pasted and the label image of the target label can be image recognized and matched by image recognition technology to determine whether the two label images are the same, but such a matching method has a large amount of calculation and consumes more time. Therefore, in the embodiment of the present application, a matching method with a smaller amount of calculation and a faster calculation speed can be used to perform multiple levels of matching, which can not only quickly complete the matching and determine whether the label is correct, but also has lower requirements on the computing power of the labeling machine controller, and can be applied to devices with lower computing power.

[0042] Step 103: Use a preset matching method to match the label to be pasted with the target label, and if the matching is successful, control the labeling machine to paste the label to be pasted to a specified position of the target device.

[0043] Among them, the preset matching method includes at least one of the following: judging whether two labels are the same based on label size information, judging whether two labels are the same based on color similarity, and judging whether two labels are the same based on content information contained in the labels; the color similarity is calculated based on the pixel color ratio of the two label images; the pixel color ratio is used to indicate the pixel ratio corresponding to each color in the label image.

[0044] Exemplarily, in an embodiment of the present application, firstly, it is determined whether two labels (i.e., the target label and the label to be pasted) are the same based on the label size information. If the label sizes of the two labels are different, it can be directly determined that the label to be pasted is not the label to be pasted at the moment. Otherwise, it is determined whether the two labels are the same based on the color similarity. If the color similarity of the two labels is less than the preset similarity threshold, it can be directly determined that the two labels are different. Otherwise, it is further determined whether there is a label among the above-mentioned multiple labels whose color similarity with the label to be pasted is greater than or equal to the preset similarity threshold. If not, it can be determined that the label to be pasted successfully matches the target label, that is, the label to be pasted is the label that needs to be pasted at the current moment. Otherwise, it is necessary to further use image recognition technology to determine whether the contents of the two labels are the same.

[0045] It can be understood that in the embodiments of the present application, in most cases, it is only necessary to calculate the size of the label and count the pixel colors of the label image to complete the label matching. Compared with the matching method in the related art, the amount of calculation is greatly reduced.

[0046] Specifically, in the above step 103, the step of determining whether the two labels are the same based on the label size information may further include the following steps 103a, 103b, 103c and 103d: Step 103a: Acquire label size information of the label to be pasted, and based on a comparison result between the label size information of the label to be pasted and the label size information of the target label, determine whether the label to be pasted is the same as the target label.

[0047] Exemplarily, the label size information of the label to be pasted can be calculated through the label image captured by a camera arranged on the labeling machine, and the label size information of the target label can be directly obtained from the production execution system.

[0048] Specifically, the above step 103a may further include the following steps 103a1 and 103a2: Step 103a1, calculating a first difference between the length of the label to be pasted and the target label, and calculating a second difference between the width of the label to be pasted and the target label.

[0049] Step 103a2: When the first difference is smaller than a first preset difference threshold, and / or the second difference is smaller than a second preset difference threshold, determine that the label to be attached is the same as the target label.

[0050] Exemplarily, when the lengths and / or widths of two tags are different, it can be directly determined that the two tags are different tags. In this case, it can be directly determined that the two tags fail to match without performing calculations in subsequent steps.

[0051] Step 103b: when the comparison result indicates that the label to be pasted is the same as the target label, calculate the first color similarity between the label to be pasted and the target label, and determine whether the label to be pasted is the same as the target label based on the first color similarity between the label to be pasted and the target label.

[0052] Step 103c: when the first color similarity indicates that the label to be pasted is the same as the target label, calculate the second color similarity between the label to be pasted and other labels among the multiple labels except the target label, and determine whether the label to be pasted and the other labels have the same label based on the second color similarity between the label to be pasted and the other labels.

[0053] Specifically, the color similarity of any two labels in the above steps 103b and 103c is obtained based on the following steps 103b1 to 103b3: Step 103b1, obtain the color corresponding to each pixel in the first label image of the first label, calculate the number of pixels corresponding to each color, and based on the number of pixels corresponding to each color, calculate the proportion of pixels corresponding to each color in the first label image; and obtain the color corresponding to each pixel in the second label image of the second label, calculate the number of pixels corresponding to each color, and based on the number of pixels corresponding to each color, calculate the proportion of pixels corresponding to each color in the second label image.

[0054] Step 103b2: Calculate the difference in pixel proportions corresponding to each color in the first label image and the second label image to obtain the difference in pixel proportions corresponding to each color.

[0055] For example, in the embodiment of the present application, colors can be divided into red, orange, yellow, green, cyan, blue and purple, or red, green and blue, and each color has a corresponding red, green and blue (RGB) value range. When calculating the pixel ratio, the RGB value of each pixel in the label image can be obtained, and the color corresponding to each pixel can be determined according to the RGB value range corresponding to each color. After that, the number of pixels contained in each color is counted, and the pixel ratio corresponding to each color is calculated.

[0056] Step 103b3: Perform a weighted summation on the pixel ratio differences corresponding to each color to obtain the color similarity between the first label and the second label.

[0057] The first tag is one of the two tags, and the second tag is the other of the two tags.

[0058] For example, after calculating the pixel ratio corresponding to each color of the label image, the pixel ratio difference corresponding to each color of the two label images can be calculated, and the color similarity of the two labels can be obtained by weighted summation based on the pixel ratio difference.

[0059] For example, taking the colors red, green and blue as an example, the pixel proportions of each color of label 1 (i.e. the label to be attached) are 10%, 70% and 20% respectively; the pixel proportions of each color of label 2 (i.e. the target label) are 11%, 68% and 21% respectively. The difference in pixel proportions of the two labels are -1%, 2% and -1% respectively. Taking the weight of each color as an example, the weighted sum is 0, and the color similarity of the two labels is 100% after subtracting this value from 100.

[0060] It should be noted that the color similarity calculation method provided in the embodiment of the present application sets an RGB value range for each color, and therefore, the influence of color difference can be ignored to a certain extent.

[0061] Step 103d: When the second color similarity indicates that the label to be pasted is different from the other labels, determine that the label to be pasted is successfully matched with the target label.

[0062] Exemplarily, when the color similarity between the label to be pasted and the target label is calculated to be greater than or equal to a preset similarity threshold based on the color similarity calculation method, it is necessary to further calculate the color similarity between the label to be pasted and other labels among the multiple labels except the target label. If the color similarities with other labels are all less than the preset similarity threshold, it can be determined that the label to be pasted matches the target label successfully. Otherwise, it is necessary to use image recognition technology to determine whether the label contents of the two labels are the same.

[0063] Specifically, the above step 103d may further include the following steps 103d1 and 103d2: Step 103d1: when the second color similarity indicates that there is a label to be identified that is the same as the label to be attached among the other labels, use image recognition technology to identify whether the label content of the label to be attached is the same as that of the label to be identified.

[0064] Step 103d2: When the label contents of the label to be attached and the label to be identified are different, it is determined that the label to be attached is successfully matched with the target label.

[0065] Exemplarily, after it is determined that the label to be pasted matches the target label successfully, the label can be pasted to a designated position of the target device.

[0066] In a possible implementation, the above step 103 may further include the following step 103e: Step 103e: when the comparison result indicates that the label to be pasted is different from the target label, or the first color similarity indicates that the label to be pasted is different from the target label, or the label content of the label to be pasted is the same as that of the label to be identified, it is determined that the label to be pasted fails to match the target label, and an alarm is generated.

[0067] The warning reminder is used to remind the user that an error occurs in the label currently pasted.

[0068] Exemplarily, when it is determined in any of the above steps 103a, 103b, 103c and 103d that the two labels are different, it can be determined that the label to be pasted fails to match the target label, that is, the two labels are different labels, and the label to be pasted is not the label that needs to be pasted currently.

[0069] Optionally, in an embodiment of the present application, in order to prevent the user from erroneously entering the next step before the labels are pasted, it is necessary to prohibit the user from executing the operation of the next step before all the labels are pasted.

[0070] Exemplarily, after the above step 103, the label error prevention control method provided in the embodiment of the present application may further include the following step 104: Step 104: Send a paste success message to the production execution system.

[0071] The paste success message is used to allow the production execution system to allow the user to perform related operations of subsequent processes when each of the multiple labels is pasted to the designated position of the target device.

[0072] For example, after the labeling machine completes the pasting of each label, the labeling machine controller will send a success message to the production execution system, and the production execution system will determine whether the pasting of all labels has been completed. If so, the user can be allowed to perform related operations of subsequent processes.

[0073] Optionally, in an embodiment of the present application, the production execution system can display all labels in the production task list of the current device (i.e., the above-mentioned target device) in the form of images in the front-end window of the production execution system. Each label has a corresponding image and material code. When the label pasting process is operated, one-to-one operations are performed according to the label image and material code displayed in the front-end window of the production execution system. The automatic labeling machine pastes the labels and checks the number of labels in the production task list. When all labels are pasted, click the confirmation button in the window interface to continue with the subsequent process operations. This solves the problem of relying on manual memory recognition and operating based on experience, so that each label has a reference basis for pasting, avoiding the situation of incorrect label pasting, greatly improving the overall assembly efficiency and quality, and meeting the production needs of diversified machine configuration.

[0074] Specifically, Figure 2 As shown, it is a flow chart of the control method for label error prevention provided by the embodiment of the present application. First, when a label is added (for example, a newly coded label CP5901G000000000 is introduced), the product manufacturing MPE engineer initiates the material application notification engineering change notification ECN process, and publishes the coded label to the product lifecycle management PLM system. After the ECN process is reviewed, the PLM system automatically synchronizes the material code (CP5901G000000000) and specification sheet (including label size information, label image, etc.) of the label to the MES background system small piece picture prompt maintenance resource pool. When a label coded with CP5901G000000000 is used in a production order for a certain model, the MES backend system automatically obtains (see Figure 6 for the relevant program implementation) the specification sheet of the label coded with CP5901G000000000 in the order through the material code in the resource pool. The MES backend system pushes (see Figure 7 for the relevant program implementation) the received CP5901G000000000 label and specification sheet to the MES front-end small item picture display window for use in the labeling process.

[0075] When different models and different configuration labels are released, the PLM system will release the coding specification according to the pseudo-noise PN code of the label. After the ECN process review is completed, the PLM system will automatically synchronize the label specification to the MES backend system. When the label is used in the production order, the label code and specification will be available in the MES system (for example, the bill of materials for 2NF5466M7C0002T). During machine production and assembly, after scanning the machine serial number at the label pasting process station, when pasting the label (the production process information indicates the pasting position information), each time the PN code of the label in the production order is scanned, the label becomes selected in the MES front window, and the corresponding label is pasted according to the label code and specification shown in the window icon. The automatic labeling machine pastes the label, checks the number of labels in the task sheet, and when all the label specifications displayed in the front window are selected (that is, when all the labels in the production order have been pasted), the "Confirm" button in the MES front window becomes clickable. Click the "Confirm" button to close the front window, and all the labels in the production order have been pasted, indicating that the label pasting process is completed and the subsequent process is continued. If there are unselected label specifications in the MES front-end window, it means that all labels in the production order have not been pasted. At this time, the "Confirm" button is not clickable, and you cannot click the "Confirm" button to close the front-end window to avoid missing labels. The entire label pasting operation process is controlled by the program, which greatly improves the efficiency and quality of label pasting, and optimizes the problems that affect assembly efficiency and quality, such as label pasting errors and omissions during the assembly process.
