Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic manufacturing, and particularly relates to a PCBA first piece detection method and system, an electronic device and a storage medium. BACKGROUND

[0002] PCBA (Printed Circuit Board Assembly) first inspection: PCBA board first inspection is to check the first or first few products produced in each batch in the production process. This operation is necessarily a sample extracted before mass production, so it is also called first inspection. The number of first inspection varies according to the requirements of enterprises or customers, and the product will be put into mass production only after the first inspection is qualified. The first piece inspection in the production process is mainly to prevent batch over-difference, repair, scrap and other problems of products, and it is a means of pre-controlling product production process, an important method of product process quality control, and an effective and essential method for enterprises to ensure product quality and improve economic efficiency. Long-term practice has proved that the first inspection system is an effective measure to find problems as soon as possible and prevent batch scrap.

[0003] Through the first piece inspection, it can be found whether the product has component missing, position deviation or reverse, component polarity error or loss, material or formula error and other problems, so that corrective or improvement measures are taken to prevent batch unqualified products. The first piece inspection and confirmation are needed for the first batch production of new products and the semi-finished products and finished products generated after the change of materials and specifications. The first piece record should be completed in time during the first piece inspection, and the first piece confirmation form should be filled out.

[0004] In the traditional way, PCBA first piece detection is generally performed by one person using a magnifying glass to visually inspect the physical PCBA. When the number of components of the PCBA is large, one person's inspection is time-consuming, which can easily injure the eyes of the worker, and the inspection error rate is increased due to the long-time online work of the worker.

[0033] The present application will be further described in detail below in conjunction with specific embodiments, but the embodiments of the present application are not limited thereto.

[0034] Embodiment One

[0035] Please refer to Figure 1 , Figure 1 is a flowchart of a PCBA first piece detection method provided by an embodiment of the present application, and the embodiment provides a PCBA first piece detection method, which can include the following steps.

[0036] Step 1, obtaining a whole-board virtual assembly diagram, a PCBA physical image, and a first CAD component list.

[0037] The whole-board virtual assembly diagram is an image of a simulated assembly of all components in a designed file, the PCBA physical image is a corresponding image of a PCBA board, and the first CAD component list includes all components in the designed file. The first CAD component list includes the position number, material number (i.e., material code), polarity, front and back, and inspection times of the components.

[0038] In addition, the embodiment also pre-sets a component library, which saves the material code, component physical image (also referred to as component image, for example, as shown in Figure 2 ), and inspection frame size of all existing components. The inspection frame size corresponds to the size of the components.

[0039] In one specific embodiment, step 1 can specifically include steps 1.1-1.3, in which:

[0040] Step 1.1, forming a whole-board virtual assembly diagram in combination with a BOM (Bill of Material) and a CAD design file.

[0041] Specifically, the CAD design file includes component name, position number, material code, component polarity, front and back, position coordinates, angle, and setting component virtual inspection frame size. After reading in the BOM and combining with the CAD design file, a whole-board virtual assembly diagram (silk screen, solder pad) is formed.

[0042] Step 1.2, obtaining a PCBA physical image corresponding to the PCBA board.

[0043] Specifically, by scanning the PCBA board through AOI (Automated Optical Inspection) or taking a photo, a PCBA physical image can be obtained by setting the physical size of the PCBA picture, wherein the PCBA physical image has the same size as the whole-board virtual assembly diagram.

[0044] Step 1.3, forming a first CAD component list including all components based on the CAD design file.

[0045] Specifically, the CAD design file is used to call the position number, material number, polarity, front and back of the required components in the first CAD component list, and the number of checks in the first CAD component list is defaulted to 1.

[0046] In addition, a virtual first-piece detection diagram can also be generated, specifically by overlapping the whole-board virtual assembly diagram and the PCBA physical image 1:1 (i.e. overlapping the front and front, and the back and back in the direction of the board), to obtain the virtual first-piece detection diagram.

[0047] Step 2, multiple check setting and check condition.

[0048] (1) If the component on the whole-board virtual assembly diagram has polarity, set the number of multiple checks n, wherein n≥2, for example, double check: manual check twice by different personnel.

[0049] (2) If the component on the whole-board virtual assembly diagram has no polarity, set single check.

[0050] (3) Check condition: take the whole-board virtual assembly diagram as the reference to judge whether the component on the PCBA physical image is missing, reversed, or offset, and take the physical component image as the reference to judge whether the component on the PCBA physical image is wrong material / damaged, i.e. check whether the component in the PCBA physical image is missing, reversed, offset, or wrong material / damaged.

[0051] Step 3, extract component list L4 from the first CAD component list, wherein the component list L4 includes all components for first-piece detection.

[0052] Specifically, select the components for first-piece detection from the first CAD component list to generate the component list L4, and the components for first-piece detection are pre-set, such as the front and / or back in the first CAD component list, or the front+back, or manually select the components.

[0053] Step 4, set the number of checkers and distribution condition setting.

[0054] a, set the number of checks:

[0055] (1) Set the PCBA first piece inspection time t.

[0056] (2) Get the total number of component inspection times Q on component list L4.

[0057] (3) The estimated time for one person to handle one component is t1, which can be an empirically set value at the beginning, and can be continuously updated according to the average time of single component inspection in the report. The updating method is to average all the average times of single component inspection in the report.

[0058] (4) Task number: n1 = Q * t1 / t.

[0059] b, allocation condition setting:

[0060] (1) Recommend a single group quantity g, which is the number of components displayed on the interface at a time when the current task number is executed.

[0061] (2) The same material code is divided into the same group.

[0062] (3) Whether to zero (i.e. whether to display the virtual assembly diagram single frame and the PCBA real object image single frame at 0°, rotate to zero according to the angle of the CAD design file), generate zero data, for example, Figure 5 The component angle of the virtual assembly diagram single frame on the left side of the middle is 90°, Figure 5 The component angle of the virtual assembly diagram single frame on the right side of the middle is 0°.

[0063] Step 5, in the service end, update the first CAD component list based on the component inspection times in the multiple inspection settings, get the second CAD component list, generate the task list based on the component list L4, generate the inspection list based on the second CAD component list and the component list L4, and distribute the current task number in the task list to n1 users without the current task (in actual application, preferentially: distribute the task number to each user relatively evenly).

[0064] In one specific embodiment, updating the first CAD component list based on the component inspection times in the multiple inspection settings to get the second CAD component list includes:

[0065] When the component has polarity, update the inspection times in the first CAD component list to n according to the number n in the multiple inspection settings, and when the component has no polarity, keep the inspection times in the first CAD component list as 1, to generate the second CAD component list according to the first CAD component list after setting the inspection times.

[0066] It should be noted that the bit number of the element can also be set alone.

[0067] In addition, the server generates a task list, which includes a task number, a state, and a result. The result is empty by default at the beginning. The state is divided into: completed, uncompleted, void, and closed, and the default is uncompleted at the beginning.

[0068] The task number is generated according to the selected element list L4 in the first CAD element list. The selection method is as follows: the task number is generated according to the front and / or back in the first CAD element list. The front is task 1, the back is task 2, or the front + back is task 1. The element can also be selected manually to generate the corresponding task number. The selection method is not limited.

[0069] In one specific embodiment, an inspection list is generated based on the second CAD element list and the element list L4, including:

[0070] The inspection list is generated according to the inspection times in the second CAD element list and the element list L4. The total number of elements to be inspected in the inspection list is the sum of the inspection times of the element list L4. The inspection list includes a bit number, an inspection result, a user, a state, and a task number. The state indicates whether it is occupied, such as FALSE indicating unoccupied and TRUE indicating occupied.

[0071] In one specific embodiment, the current task number in the task list is assigned to at least n1 users who do not have the current task, including:

[0072] A user task list is generated.

[0073] The current task number in the task list is assigned to at least n1 users who do not have the current task in the user task list.

[0074] Specifically, the user task list is generated according to the users who can assign tasks. When assigning tasks, the user is selected to be no less than n1 in number. The task number is assigned to the user who does not have the current task, i.e., the user end corresponding to the user. The user is the personnel who performs the task.

[0075] Then, the server starts a timing instruction: start timing T.

[0076] Step 6, in the user end, the current task number is obtained based on the task list, and the state of the current task number is obtained. When the state of the current task number is uncompleted or completed, the updated inspection list according to the state and the inspection result in the inspection list is obtained.

[0077] Specifically, the current task number is acquired based on the task list, if not, the process is ended, if yes, the state of the current task number is acquired, if the state of the current task number is invalid or closed, the user is prompted with the state and the process is ended, if the state of the current task number is unfinished or completed, the check list after the state and the check result in the check list are acquired.

[0078] That is, the user logs in the request service, the user acquires the current task number in the user task list, if not, the process is ended, if yes, the state is inquired in the task list, if invalid or closed, the user is directly prompted with the state and the process is ended, if unfinished or completed, the next step is performed.

[0079] In one embodiment, the check list after the state and the check result in the check list are acquired, including:

[0080] S1, the list L1 is acquired, the list L1 is the element with the state of unoccupied in the check list and the check result of empty in the check list.

[0081] S2, when the list L1 is empty and the check result in the check list is empty, the current user is reminded that there is another user to perform the task, at this time, the other user continues to perform the task, when the list L1 is empty and the check result in the check list is not empty, the process is ended and the current user is prompted with the completion of the check, and the element of failure is displayed again to make the user check the correctness of the check result of the element and end the timing T1.

[0082] S3, when the list L1 is not empty, the element of multiple checks that has been checked by the current user is excluded to generate the list L2.

[0083] Specifically, if the element of multiple checks has been checked by the current user, the element checked by the current user is removed from the list L1 to generate the list L2.

[0084] S4, when the list L2 is empty and the element with the check result of empty in the check list, the current user is reminded that there is another user to perform the task, at this time, the other user continues to perform the task, when the list L2 is empty and the element with the check result of not empty in the check list, the process is ended and the current user is prompted with the completion of the check, and the element of failure is displayed again to make the user check the correctness of the check result of the element and end the timing T1.

[0085] S5, when the list L2 is not empty, the list L2 is updated based on the grouping of the same material code to generate the list L3.

[0086] Specifically, if there are components with the same material code and the components with the same material code have been classified into the same group, the number of components classified into the same group is greater than or equal to the single group number g, and the components are prioritized, the list L2 is updated to generate the list L3 through the updated list L2; if there are no components with the same material code, the query sorting in the list L2 is defaulted, and the list L3 is generated, that is, the list L2 is the list L3.

[0087] It should be noted that the list L1, the list L2 and the list L3 are dynamic and are constantly updated as the task is performed.

[0088] S6, whether to zero according to the setting of the distribution condition, if zero, display through the zero interface, the zero interface is as shown in Figure 6 , if not zero, display through the non-zero interface, the non-zero interface is as shown in Figure 7 , the distribution condition setting is whether to display the virtual assembly diagram single frame and the PCBA real object image single frame at 0°, if yes, zero, if no, not zero.

[0089] S7, according to the single group number g, the element information corresponding to the position number of the list L3 is displayed in order, and the element information includes the virtual assembly diagram single frame, the PCBA real object image single frame and the element image.

[0090] Specifically, according to the g value set by the single group number, the first g number of element information in the list L3 is pushed to the user interface, and then g element information is displayed in order each time, and when the last g is not enough, all the remaining ones are displayed.

[0091] The interface display content includes: virtual assembly diagram single frame (display single frame according to check box size), PCBA real object image single frame, element image, selection box OK / NG, button previous group, next group, all pass, for example as shown in Figure 8 ; in addition, if it is a plug-in, the PCBA real object image single frame and the welding surface also need to be displayed.

[0092] In the check box on the interface as shown in Figure 8 , the virtual assembly diagram single frame (the virtual assembly diagram is rotated to zero according to the angle of the CAD design file, and is displayed at 0°), the PCBA real object image single frame (the PCBA real object image is rotated to zero according to the angle of the CAD design file, and is displayed at 0°), and the element image are displayed in the check box.

[0093] S8, update the state and username corresponding to the position number in the inspection list, and obtain the inspection result of the inspection list corresponding to the position number based on the element information, until the inspection result in the inspection list is not empty.

[0094] Specifically, the state corresponding to the bit number in the check list is changed to TRUE, indicating occupation, and the user is changed to the requested username.

[0095] After that, the user checks to determine whether the check result corresponding to the bit number is OK or NG, OK representing a normal result, i.e., passing, and NG representing an abnormal result, i.e., not passing. It should be noted that the present embodiment does not limit OK and NG, and they can also be pass and fail, or other relative phrases.

[0096] Therefore, after completing a group, the cycle according to step 6 is performed until the task check assigned to the current user is completed.

[0097] Step 7, on the server, after the results in the check list are all updated, the task list with the state closed and the current task number cleared is obtained, and a report of the current task number is generated and output.

[0098] In one specific embodiment, step 7 can specifically include steps 7.1-7.2, in which:

[0099] Step 7.1, if the check results of the bit numbers corresponding to the current task number in the check list are all not empty, then the task list with the state all updated to complete is obtained, and the overall test result is assigned to the result in the task list.

[0100] Specifically, the system administrator logs in to the server and checks whether the current task number in the task list is complete. It is checked whether the check results of the bit numbers corresponding to the current task number in the check list are empty. If yes, it is not complete, i.e., the client user continues to complete it; if not, it is complete, the state in the task list is changed from not complete to complete, and the timing T1 is ended; and the overall test result is assigned to the result in the task list, wherein as long as one element appears NG, the conclusion is overall NG.

[0101] Step 7.2, the task list with the state closed and the current task number cleared is obtained, and a report of the current task number is generated and output.

[0102] Specifically, the system administrator closes the task, finds the task number in the task list, changes the state to closed, and clears the task number in the user task list. The report of the task number is output.

[0103] Preferably, the report includes the final check result of the current task number, and / or the passing rate, and / or the average time for single element check, and / or the bit number, and / or the overall result of the bit number, and / or the inspector, and / or the result of single bit number, and / or the number of times.

[0104] Further, the report content of the output report (at least including the following 4 parts of content) is:

[0105] (1), the final check result of this task number is NG or OK (as long as one element appears NG, the conclusion is overall NG, that is, the result is NG).

[0106] (2), the passing ratio is calculated by the following proportion method:

[0107] The first kind: the passing ratio is calculated according to the elements, and the passing ratio = (the total number of element list L4-the number of NG in element list L4) / the total number of element list L4.

[0108] The second kind: the passing ratio is calculated according to the number of inspections, and the passing ratio = (the total number of element inspections-the number of NG) / the total number of element inspections.

[0109] (3), the calculation method of the average time of single element inspection is as follows:

[0110] The average time of single element inspection = (T1-T) / the total number of element inspections, T1-T is the total time, and the unit is second.

[0111] (4), the specific report is shown in Table 1 (the NG is arranged in the front), and the report contains the signatures of inspectors, supervisors, QA and other related personnel. Whether the bit number is OK / NG as a whole: for example, if this bit number is checked by two users, and both users check OK, then the bit number is OK as a whole; if one of the two users checks NG, then the bit number is NG as a whole.

[0112] Table 1

[0113]

[0114] The present application generates an element list L4 including all elements of the first piece detection, and generates a task list and an inspection list on the server, so as to distribute the current task to be executed to the user end of the user who needs to execute the task. Then, on the user end, the user can execute the task of the current task number which is in the state of completion or incompleteness, so as to obtain an inspection list with inspection results, and finally output the corresponding report. Therefore, the present application can dynamically distribute detection tasks, can perform first piece detection in parallel by multiple people, can set multiple re-inspections or cross inspections, save time and reduce the error rate of inspection.
