Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings, but the described embodiments of the present invention are a part of the embodiments of the present invention, not all of the embodiments of the present invention.
In the prior art, the conventional AOI scanning maintenance statistical method at present is that an operator manually records position coordinates of defects and circuit board material numbers on paper according to the condition after AOI scanning, then judges the defect type according to an enlarged defect position image, and continuously records on the paper; after the overhaul of a batch is completed, the recorded paper is handed over to the next operator or the current operator, the records are sequentially input into a computer and recorded in an electronic form, so that the efficiency is low, the conditions of omission, cross recording, confusion recording and the like exist, the rework probability is increased, and the efficiency of the detection link is not improved.
One aspect of the embodiment of the application provides an automatic generation method for an AOI maintenance report of a printed circuit board, which is used for realizing defect statistics of the printed circuit board which completes AOI scanning, and is realized through a computer program, and an operator or a user only needs to select a corresponding defect name on a display interface according to an amplified defect image. As shown in fig. 1, the method of the present example includes the steps of:
s100, recording the material number and the coordinates of each defect position of the current printed circuit board to be detected when at least one defect position is detected according to the AOI scanning result of the current printed circuit board to be detected; the method mainly comprises the steps of utilizing a program to judge and record whether the printed circuit board has a defect, recording the material number and the coordinates of the defect position if the printed circuit board has the defect, ending the process if the printed circuit board has no defect, and executing S100 on the next printed circuit board.
The defect position coordinate is a coordinate with a certain vertex angle, or the center in the length and width directions of the printed circuit board to be detected as the origin of coordinates, and the defect position is equivalent to the coordinate of the origin of coordinates. In the process, if the circuit board only has one defect position coordinate, the material number of the circuit board is recorded, for example, YCL-DC-001, and the defect position coordinate is recorded, for example, the coordinate origin is the lower left corner of the circuit board, and the defect position coordinate is (32.04, 21.13) in mm. If the circuit board has two defects, the material number YCL-DC-002 is recorded, and two defect position coordinates (12.34, 51.33), (26.53, 34.06) are recorded at the same time.
S200, amplifying the printed circuit board image in the area corresponding to each defect position coordinate, wherein the image of the whole printed circuit board is acquired through AOI scanning, and the amplified image of the defect position is conveniently presented on a display interface of display equipment for a user/an operator to confirm/record the defect type. Wherein one defect position coordinate corresponds to one enlarged image. The defect location coordinate corresponding region is a circular region having a predetermined radius range with the defect location coordinate as a center, or a regular polygon region having a predetermined side length, or a rectangular region having a predetermined length and width, and generally, a rectangular region such as a square or a rectangle is often used.
S300, sequentially displaying the amplified images on a display interface of the display device, and displaying a first interaction object area on the display interface aiming at the display of each amplified image, wherein the first interaction object area is a defect name selection area, so as to form a mode for a user to observe and analyze and select and confirm defect types. As shown in fig. 2, on the display interface 101 of the display apparatus 100, an enlarged image is displayed, and a first interaction object region 200 is displayed in the lower right corner of the display interface 101. Specifically, the first interaction object area 200 may also be displayed in the lower left corner, or the upper right corner of the display interface 101, and may be set according to the operation habit of the user. The first interaction object region 200 covers the magnified image displayed on the display interface 101, and generally, the area occupied by the first interaction object region 200 is not too large, so as to avoid the influence of shielding the magnified image on defect judgment and recording, and the area occupied by the first interaction object region 200 on the display interface 101 is not more than 1/8, so that a user can conveniently judge the defect according to the magnified image displayed in the main region of the display interface 101.
Specifically, as shown in fig. 3, a plurality of first interactive objects 201 and a second interactive object 202 are displayed in the first interactive object area 200, each first interactive object 201 corresponds to a different defect name, and the second interactive object 202 may be an "ok" button. In fig. 3, it can be seen that 6 first interactive objects 201 are displayed in the first interactive object area 200, and correspond to different defect names: the notch, the missing weld, the wiping, the residual copper, the short circuit and the pinhole. The first interactive object 201 and the second interactive object 202 both have two states, and are displayed as a convex state when not selected by the user in the first state, and are displayed as a concave state when selected by the user in the second state; a circular or square checkbox may be provided on one of the top, bottom, left, and right sides of each interactive object, the checkbox being filled in when the checkbox is not selected in the first state, and filled in when the checkbox is selected in the second state.
Specifically, the user may touch the position of the display interface 101 of the display device 100 corresponding to each interactive object, and touch and click once, that is, change the state of the interactive object once; or when the user moves the mouse pointer to the position of each interactive object through mouse operation, the state of the interactive object can be changed by clicking the left button of the mouse once, so that the reset after selection or wrong selection is facilitated.
S400, after a user judges the defect type/name according to the currently displayed enlarged image, selects the corresponding defect name in the first interactive object 201 and selects 'confirm' of the second interactive object 202, the defect name corresponding to the first interactive object 201 in the second state is recorded in response to the change from the first state to the second state of the second interactive object 202 and the first interactive object 201. As shown in fig. 4, it can be seen that the "notch" and the "pinhole" in the first interactive object 201 are selected and displayed as the second-state recess, and at the same time, the "confirmation" of the second interactive object 202 is selected and displayed as the second-state recess, the circuit board recording the current material number (for example, YCL-DC-001) has two defects, i.e., the "notch" and the "pinhole" at the current defect position coordinates (32.04, 21.13).
S500, judging whether the currently displayed amplified image is the last amplified image of the current printed circuit board to be detected:
if so, indicating that all defect positions of the current printed circuit board are selected and the defect names are recorded, clearing the display of the display interface 101, skipping to S100, and starting to execute S100 on the next printed circuit board to be tested until the printed circuit boards of one batch are repaired;
if not, it indicates that the current printed circuit board has defect names of other defect positions to be selected and recorded, a next enlarged image (i.e., of another defect position of the circuit board) is displayed on the display interface 101 as a currently displayed enlarged image, the first interactive object 201 and the second interactive object 202 of the first interactive object area 200 are both initialized to the first state, so that the user can judge a new enlarged image again and make a selection in the first interactive object area 200, and S400 is executed again.
In the case of a current printed circuit board having more than one defect position, for example, two, such as the printed circuit board with the material number of YCL-DC-002 as exemplified above, there are two defect position coordinates (12.34, 51.33), (26.53, 34.06). Through the first pass of S300-S400, the defect recorded at the first defect position coordinate (12.34, 51.33) is 'scratch'. At this time, it is determined in S500 that the last magnified image is not the last magnified image, because there is a magnified image corresponding to the second defect position coordinate (26.53, 34.06), the magnified image corresponding to the coordinate (26.53, 34.06) replaces/covers the currently displayed image on the display interface 101 as the currently displayed magnified image, and at the same time, the first interactive object 201 and the second interactive object 202 in the first interactive object region 200 are both initialized to the first state, that is, the previously selected objects are both reset to the unselected state, such as the protruding state. Then, S400 is executed, after the user selects corresponding defect names, such as "short" and "pinhole", and selects "confirm", the printed circuit board with the material number YCL-DC-002 is recorded, and the defects at the defect position coordinates (26.53, 34.06) are "short" and "pinhole". Then, the processing of all the defective positions of the material number circuit board is completed, and the process jumps back to S100 to execute the processing of the next circuit board of the same batch.
S600, after the printed circuit boards of a batch are overhauled, the recorded material numbers, defect position coordinates, defect names and corresponding relations are stored and output in a table form, wherein one material number corresponds to a plurality of defect position coordinates, and one defect position coordinate corresponds to a plurality of defect names.
As shown in fig. 9, an example of a table is formed, in which the material number YCL-DC-001 has one defect and two defect position coordinates (32.04, 21.13), and the defect names have "notch" and "pinhole", respectively; the material number YCL-DC-002 has two defects, the defect at (12.34, 51.33) is 'scratch', and the defect at (26.53, 34.06) is 'short circuit' and 'pinhole'.
When the table is formed, each defect position coordinate may correspond to one row, and the defect name may have a plurality of columns, each column displaying one defect name. If one material number has a plurality of defect position coordinates, displaying a plurality of lines according to the defect position coordinates, wherein the material number of each line is the material number; the defect name is displayed by filling from the first column of the defect name column, and if the current defect position coordinates have a plurality of names, the defect names are displayed by filling in the defect name column in sequence.
After the defect tables of the circuit boards in a batch are generated, the defect positions corresponding to each material number can be automatically calculated according to the statistical conditions in the tables, and each defect position corresponds to several defect types; for example, when one material number has multiple rows, the units where the material numbers are located can be combined; and two columns are added in the subsequent columns of the table: one column is the number of defect positions, and one column is the number of defect types, which can be automatically calculated by a program according to the table filling condition. Through the display of the number of defect positions and the number of defect types of each material number, more statistical conclusions can be provided for a generation manager, and the production support is provided.
In practical applications, a new defect form may occur, i.e. the preset type of the second interactive object 202 cannot meet the requirement, and the new defect form cannot find a suitable option in the second interactive object 202. To this end, the present example proposes the following preferred solutions:
as shown in fig. 5, a third interactive object 203 is also displayed in the first interactive object area 200; the third interactive object 203 corresponds to an "other defect" button.
Thus, in S400, in response to the user' S interaction with the first interactive object region 200 according to the currently displayed magnified image, when the third interactive object 203 changes from the first state to the second state, that is, "other defects" are selected, the defects indicated by the currently listed second interactive object 202 cannot meet the requirement, special or rare defect forms are encountered, or defect types that need to be manually defined are selected, and the second interactive object region 300 is displayed in the display interface 101, as shown in fig. 6, the size of the second interactive object region 300 is equivalent to the size of the first interactive object region 200, and a frame can be shared therein, and the position does not obscure the analysis and observation of the magnified image. As shown in fig. 7, a plurality of fourth interactive objects 301 are displayed in the second interactive object area 300, and the fourth interactive objects 301 are text input boxes for users to input defect names.
Thus, when the second interactive object 202 changes from the first state to the second state, and at least one first interactive object 201 changes from the first state to the second state, and/or at least one fourth interactive object 301 has a defect name input by the user, the defect name corresponding to the first interactive object 201 in the second state and/or the defect name in the fourth interactive object 301 are recorded.
For example, in fig. 7, if the user inputs "poor exposure" in one fourth interactive object 301 and "poor etching" in another fourth interactive object 301, the defect name corresponding to the current defect position coordinate is recorded as "poor exposure" and "poor etching" if the user clicks "confirm" of the second interactive object 202. If a defect of the first interactive object 201, such as "residual copper", is also selected, the defect names corresponding to the current defect position coordinates are recorded as "residual copper", "poor exposure", and "poor etching".
In practical application, in order to avoid the defect selection operation by a person without operation authority, that is, to ensure that each post is operated by a special post specialist, an operation authority authentication link is introduced in the preferred mode of the embodiment.
In S400, the user refers to an operator authenticated by the operation authority. In the preferred embodiment, the operation authority authentication includes the steps of:
acquiring a face image of a current operator and identifying; specifically, the image can be obtained by scanning through a camera device and identified by a face image identification program;
then, comparing the recognition result with a pre-stored face library of the authenticator: if the recognition result can find out a matched face picture in a prestored face library of the authenticator, the authentication is passed; if the matching is not found, the operation authority authentication is not passed.
The operation authority authentication step is performed when the user is ready to perform an interactive operation while facing the display device.
When the operation authority authentication is not passed, all objects of the display interface are always kept in the first state, and the current interactive operation of an operator cannot be responded.
If the operation authority authentication is passed, in S400, when recording the defect name, the name of the user and the current operation time are recorded together; each face picture in the authenticator face library and each name in a prestored authenticator name library have a one-to-one corresponding relationship; the name is a name which is searched from the name library and corresponds to the matched face picture; the current operation time comprises current year, month, day, hour, minute and second information.
Finally, in S600, the name and the operation time are also generated in the table, and the correspondence relationship is formed, as shown in fig. 10.
As a further preferable scheme of the operation authority authentication, as shown in fig. 11, a circle of light band 102 is provided on the periphery of the display interface 101 of the display device 100, the light band is an LED light bar, the LED light bar is a color-changeable light bar, and two colors, green and red, are provided. If the current operation authority passes the authentication, the light band 102 is bright green, and if the current operation authority does not pass the authentication, the light band 102 is bright red, so that the current operator can be indicated by the authentication result.
Another aspect of the embodiments of the present application provides an automatic generation device for a printed circuit board AOI maintenance report, which is used to implement defect statistics on a printed circuit board that completes AOI scanning, and as shown in fig. 8, includes: the system comprises a first recording module, an image module connected with the first recording module, a display module connected with the image module, a second recording module connected with the display module, a judgment module connected with the second recording module, and a report output module connected with the judgment module, wherein the judgment module is also connected with the display module and the first recording module.

the first recording module records the material number and the coordinates of each defect position of the current printed circuit board to be detected when at least one defect position is detected according to the AOI scanning result of the current printed circuit board to be detected. For example, the material number is YCL-DC-001, the coordinate of the defect position (the origin of the coordinate is the left lower corner of the circuit board) is (32.04, 21.13), and the unit is mm; if the circuit board has two defects, the material number is YCL-DC-002, and two defect position coordinates (12.34, 51.33), (26.53, 34.06) are recorded at the same time.
The image module acquires the amplified images of the printed circuit board in the areas corresponding to the defect position coordinates, and one defect position coordinate corresponds to one amplified image.
As shown in fig. 2, the display module is configured to sequentially display each enlarged image on the display interface 101 of the display device 100, and display a first interactive object area 200 on the display interface for each enlarged image, as shown in fig. 3, a plurality of first interactive objects 201 and a second interactive object 202 are displayed in the first interactive object area 200, where each first interactive object 201 corresponds to a different defect name, and in fig. 3, each first interactive object 201 corresponds to a different defect name: "notch", "missing weld", "wipe", "residual copper", "short circuit", "pinhole"; second interactive object 202 corresponds to an "OK" button. The first interactive object 201 and the second interactive object 202 each have two states, a first state, i.e. when not selected by the user, showing a convex state, and a second state, i.e. when selected by the user, showing a concave state.
The second recording module may respond to an interactive operation of the user on the first interactive object region 200 according to the currently displayed enlarged image, that is, when the user clicks the interactive object by touch or mouse, the state of the interactive object changes once, that is, the state may change from the first state to the second state, or from the second state to the first state. When the second interactive object 202 and at least one first interactive object 201 change from the first state to the second state, that is, the defect name is already selected, the defect name corresponding to the first interactive object 201 in the second state is recorded, as shown in fig. 4, the "gap", "pinhole", and "confirmation" are selected, and the defect names are recorded as "gap" and "pinhole".
The judging module judges whether the currently displayed amplified image is the last amplified image of the current printed circuit board to be detected:
if so, the display module clears the display of the display interface 101, and then the first recording module starts to process the next printed circuit board to be tested until the printed circuit boards of one batch are overhauled;
if not, the display module displays the next enlarged image on the display interface 101 as the currently displayed enlarged image, initializes the first interactive object 201 and the second interactive object 202 of the first interactive object area 200 to the first state, and executes the second recording module again.
And through the judgment of the judgment module and the calling of other modules according to corresponding judgment results, the defect names of all the defect positions of the current printed circuit are ensured to be selected and finished and the recording is finished, and if the defect names are not finished, the display module and the second recording module are used for continuing executing.
The report output module can store and output the recorded material number, defect position coordinates, defect names and corresponding relations thereof in a table form after the printed circuit boards of a batch are overhauled, wherein one material number corresponds to a plurality of defect position coordinates, one defect position coordinate corresponds to a plurality of defect names, and as shown in fig. 9, the report output module can perform table display on another display device or can perform printing through a printer.
As a preferred solution of this example, the display module is further configured to display a third interactive object 203 in the first interactive object area 200, as shown in fig. 5; and responding to the interactive operation of the user on the first interactive object area 200 according to the currently displayed enlarged image, when the third interactive object 203 is changed from the first state to the second state, displaying the second interactive object area 300 in the display interface 101, wherein a plurality of fourth interactive objects 301 are displayed in the second interactive object area 300, and the fourth interactive objects 301 are character input boxes for the user to input defect names. Therefore, when a new defect is faced and the defect type can be accurately extracted only by inputting the defect in a user-defined mode, the defect can be accurately defined by a user conveniently.
Thus, when the second interactive object 202 changes from the first state to the second state, and at least one first interactive object 201 changes from the first state to the second state, and/or at least one fourth interactive object 301 has a defect name input by the user, the second recording module may record the defect name corresponding to the first interactive object 201 in the second state, and/or the defect name in the fourth interactive object 301. That is, it is realized that the defect name can be defined by the fourth interactive object 301 for recording, and the conventional defect actually existing at the current defect position, such as the defect name shown by the first interactive object 201, can also be simultaneously selected and recorded, so that the flexibility and adaptability of the present example are improved.
As a further preferable solution of this example, an authority authentication module is further provided, as shown in fig. 12, connected between the display module and the second recording module, and configured to authenticate the identity card of the current operator, and ensure that all users performing operations are operators meeting authority authentication.
The authority authentication module acquires and identifies a face image of a current operator; specifically, a face image can be obtained by scanning through a camera device and is identified by a face image identification program; then, comparing the recognition result with a pre-stored face library of the authenticator: if the recognition result can find out a matched face picture in a prestored face library of the authenticator, the authentication is passed; if the matching is not found, the operation authority authentication is not passed.
The operation authority authentication performed by the authority authentication module is performed when the user is ready to perform an interactive operation while facing the display device. When the operation authority authentication is not passed, each object of the display interface 101 is always kept in the first state, and does not respond to the current interactive operation of the operator.
If the operation authority passes the authentication, recording the name of the user and the current operation time when the second recording module records the defect name; each face picture in the authenticator face library and each name in a prestored authenticator name library have one-to-one correspondence; the name is a name which is searched from the name library and corresponds to the matched face picture; the current operation time comprises current year, month, day, hour, minute and second information. Finally, in the report output module, the name and the operation time are also generated into the table, and a corresponding relationship is formed, as shown in fig. 10.
In another aspect of the embodiments of the present application, an electronic device is provided, which includes: the AOI overhaul report automatic generation system comprises at least one processor and a memory, wherein the memory stores computer execution instructions, and when the at least one processor executes the computer execution instructions stored by the memory, the at least one processor is enabled to execute the AOI overhaul report automatic generation method for the printed circuit board according to the previous embodiment.
