Detailed Description
To more particularly describe the embodiments of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an apparatus of an intelligent processing system according to an embodiment of the invention. In fig. 1, an intelligent processing system 100 is provided, according to one embodiment. The intelligent processing system 100 is applied to at least one processing device 110, the processing device 110 processes the object to be processed 200 according to the processing parameters and generates the object to be processed 220, the system 100 includes: a marking device 120, a rough judgment device 130, a fine judgment device 140, a processing information acquisition device 160, and a measurement/parameter calibration device 180. Each of the components of the intelligent processing system 100 may be implemented through software plus hardware or through pure hardware, and the invention is not limited thereto.
The marking device 120 marks processing information on the object 220, wherein the processing information includes at least one of the processing parameters. The recording method of the processing information of the marking device 120 includes characters, numbers, symbols and graphic codes, wherein the graphic codes include one-dimensional bar codes and two-dimensional bar codes. The processing information of the marking device 120 further includes a manufacturing lot, a product model, and a manufacturing date. For example: the two-dimensional graph code is printed on the printed circuit board finished product or semi-finished product, and the historical processing parameter record can be generated by scanning or identifying the two-dimensional graph code at a later date.
The rough-judging device 130 is used to initially detect whether the workpiece 220 has at least one defect and generate at least one workpiece image, wherein the rough-judging device is an automatic visual inspection device. The initial inspection method of the automatic visual inspection device comprises 3D contour comparison, position coordinate comparison, color comparison and brightness comparison. The rough judgment device 130 of the present system is usually strict in the initial judgment standard to avoid neglecting the product with the real defect, but there is a case of misjudgment, for example, a fine dust appears at a certain position in the printed circuit board, which is judged as a defect, so that the yield of the product can be ensured, and the false defect can be relatively easily judged. In the past, the above-mentioned false defects can be eliminated only by manual re-judgment, but in the present invention, the re-judgment and defect classification of defects can be performed by the above-mentioned precise judgment device 140, so that the number of false defects and the number of manual re-judgment needed can be greatly reduced.
According to another embodiment of the present invention, the automatic vision inspection apparatus comprises at least one image capturing unit, at least one distance measuring unit, a calculating unit and a database. The distance measuring unit is used for generating an image-capturing distance information for capturing the processed object. The database stores a plurality of standard dimension information, each of which includes a resolution per unit area, an image capture distance, a corresponding pixel matrix, and a corresponding actual dimension and a film thickness height. The calculating unit compares the standard size information in the database according to the resolution information of the image of the workpiece 220 and the image-capturing distance information, and calculates and generates the workpiece image with actual size information. The rough judgment device 130 can be, for example, a calculator (including a CPU and a GPU) in cooperation with an image recognition device.
The fine determination device 140, which is connected to the rough determination device 130 via signals, is used to re-check whether the processed object image has at least one defect, and identify the defect type contained in the processed object image, and generate an identification result. The precise determination device further includes a classification module 142, and the classification module 142 is implemented by applying an artificial neural network to identify the defect type. The training data of the classification module 142 includes the recognition result and the manual re-judgment result. The artificial Neural Network applied by the classification module 142 includes a Convolutional Neural Network (CNN) model. The CNN model can be selected from one of R-CNN (Region-based connected Neural Network), fast R-CNN, RPN (Region pro-potential Network), mask R-CNN and FCN (full connected Network) for defect identification and classification. In addition, besides the implementation of the convolution neural network model, other precise algorithms for classifying the components in the image can be used to implement the precise determination device 140, and the implementation manner of the precise determination device 140 is not limited in the present invention. The precise determination device 140 can effectively reduce the number of false defects and the number of manual re-determination required, and whether the manual re-determination is required can be determined by the default threshold of the measurement/parameter calibration device 180. The above false defect may be, for example, a printed circuit board, and may include: false points on the board edge, fine board scraps, dust and the daughter board to be tested are different from the mother board. The precise judgment device 140 can be, for example, a calculator (with CPU) having computing capability.
The processing information obtaining device 160 is connected to the precise determination device 140 by signal connection, and is used to identify the processing information of the processed object image and generate the processing parameters. The identification method can be character identification, image code identification, RFID and other induction tags. The processing information acquiring device 160 may be, for example, a calculator device (including a CPU and a GPU) in cooperation with an image recognition device.
The measurement/parameter calibration device 180, which is connected to the fine determination device 140 via signals, measures the defect position of the image of the workpiece to generate a defect size, calculates the optimal result of the processing parameter according to the defect size and the processing parameter to generate a calibrated processing parameter, and transmits the calibrated processing parameter to the processing device 110. The metrology/parameter calibration apparatus 180 further includes a parameter optimization module 182, wherein the parameter optimization module 182 calculates the optimal result of the processing parameters by applying an algorithm. The algorithm applied by the parameter optimization module 182 may be any algorithm that can calculate or generalize the optimal result of the processing parameters, such as: gradient descent method, newton method, conjugate gradient method, linear search, confidence domain method, neural network, particle swarm algorithm, simulated annealing, support vector machine, ant swarm algorithm, differential evolution algorithm, K-nearest neighbor algorithm (K-nearest neighbor). The measurement/parameter calibration device 180 can be, for example, a calculator (with a CPU) with computing capability.
According to another embodiment of the present invention, when the object 220 has a design drawing, the measurement/parameter calibration device 180 can further superimpose the design drawing on the image of the object 220 to be processed, which can be used as a basis for measuring the size of the defect.
According to another embodiment of the present invention, the measurement/parameter calibration device 180 further comprises a quality monitoring process, which sets at least one monitoring measurement area in the design drawing of the workpiece in advance through the measurement/parameter calibration device, and measures the monitoring measurement area of the superimposed image to generate monitoring dimension information. Wherein the quality monitoring process can be performed by general inspection or spot inspection. Taking the detection of the printed circuit board as an example, the monitoring and measuring area can be selected by frames according to a specific welding position of the printed circuit board.
According to another embodiment of the present invention, the monitoring dimension information can be further statistically generated by the measurement/parameter calibration device 180 to generate monitoring statistical information. And the monitoring statistic information is used as the data for calculating the processing parameters.
According to another embodiment of the present invention, when the defect size exceeds a threshold, the measurement/parameter calibration device 180 stops automatically calibrating the processing parameters and generates an alarm notification.
According to another embodiment, when the precise judgment device 140 receives the alert notification, the recognition result corresponding to the alert notification will not be used as the training data for training the classification module.
According to another embodiment, the warning notification can notify the system administrator in real time through short message or mail, and remind the system administrator that the identification result corresponding to the warning notification will need to be manually determined again. For example: it was found that the area of exposed nickel on the pcb was greater than 1.0cm2, and if the magnitude of the above-mentioned processing parameters could be adjusted too much according to the size of the defect, the subsequent processing flow would be seriously affected. Therefore, the size of the defect exceeding the threshold value is not used as the data source for adjusting the processing parameters and the training data.
According to another embodiment, the present invention can be applied to various stages of a manufacturing process, and referring to fig. 2, fig. 2 is a schematic diagram of an apparatus for applying an intelligent processing system to a plurality of processing equipments according to an embodiment of the present invention.
Referring to fig. 3, fig. 3 is a flow chart illustrating an intelligent processing system according to an embodiment of the invention.
In fig. 3, step 300 is to begin processing.

In step 308, the object 220 is determined by the rough determination device 130, and if the object 220 has at least one defect, the image of the object 220 is captured to generate at least one object image. The rough judgment device 130 can further calculate the actual size information of the processed object image, and the calculation method is as described above and will not be described herein again.
In step 310, the rough judgment device 130 makes an initial judgment that the workpiece 220 has at least one defective portion and judges the workpiece as a defective object, and then the process proceeds to step 312. If the rough determination device 130 initially determines that no defect is found, go to step 322.
In step 312, the processed object image is determined again by the precise determination device 140, and the defect type is identified.
In step 314, after the fine determination device 140 determines that the processed object image has at least one defect, the type of the defect is further identified, and the method for identifying the defect is as described above and will not be described herein again. If the fine judgment means 140 judges that the processed object image has no defect, the process goes to step 322 to indicate that the defect part judged by the rough judgment means 130 is a false defect.
In step 316a, the defect position is measured by the measurement/parameter calibration device 180 to generate the defect size, and the measurement method is as described above and will not be described herein again.
In step 316b, the processing information is identified and the processing parameters are generated by the processing information obtaining device 160, and the method for identifying the processing information is as described above and will not be described herein again.
In step 318, the algorithm of the measurement/parameter calibration device 180 calculates the best result of calibrating the processing parameters according to the defect size and the processing parameters, generates calibration processing parameters, and transmits the calibration processing parameters to the processing device.
In step 320, the processing device 110 adjusts the original processing parameters according to the corrected processing parameters, and jumps back to step 304 to continue processing.
In step 322, the workpiece 220 is continuously processed because there is at least one defect in the initial judgment of the rough judgment device 130 or the precise judgment of the precise judgment device 140.
Referring to fig. 4, in accordance with another embodiment of the present invention, fig. 4 is a flow chart illustrating a quality monitoring process of an intelligent processing system according to an embodiment of the present invention.
The process flow of the embodiment of fig. 3 of the present invention can be combined with the quality monitoring process flow of the embodiment of fig. 4 to increase the accuracy of calculating the above-mentioned correction processing parameters, wherein the process flows of the embodiments of fig. 3 and fig. 4 can be executed synchronously or separately.
In step 402, a measurement area to be monitored in the design drawing of the workpiece 220 is set (or selected) in the measurement/parameter calibration device 180 in advance.
In step 404, an image of the workpiece 220 is captured by the rough determination device 130.
In step 406, the design drawing of the workpiece 220 is superimposed with the processed image to generate a superimposed image.

In step 410, monitor size information is generated according to the measurement result, and monitor statistical information is further calculated.
In step 412, the monitored statistical information may be used as data for the metrology/parameter calibration device 180 to calculate calibration process parameters.

And can inspect whether the production yield meets the qualified standard (for example, the yield needs to reach 95.0%)
In step 416, the process parameters may be further measured by Virtual Metrology (VM) to increase the production yield. For example: through the virtual measurement calculation, in the process of laying a metal copper layer on a substrate when the printed circuit board is manufactured, the electroplating time of the copper sulfate bath is reduced by 0.5 second, so that the occurrence probability of short circuit of the circuit can be reduced by 1%. Therefore, the production yield can be further increased by adjusting the production parameters through the virtual measurement. By the virtual measurement, the monitored measurement area is measured without performing the steps 402-412, and instead, the yield of the product is calculated by the virtual measurement, so as to achieve the purpose of full inspection.
In summary, the embodiment of the invention provides an intelligent processing method and system, which can process and detect the production line in real time. And further, tracing, flaw judgment and correction of the processing equipment are automatically performed.
