[0034] The application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0036] The present application first describes the structure and function of the intelligent speed regulation system, then designs the speed regulation table and CPK level evaluation table, etc., based on these contents, an intelligent speed regulation strategy scheme suitable for connector production equipment is proposed, which realizes the function of calculating the best running speed value of the equipment according to the connector CPK. Finally, the interfaces of the intelligent speed regulation software such as CPK real-time monitoring, simulation speed regulation, and query historical data are designed. The following concepts are involved in the present application:

[0037] The CCD detection software is used to detect the perpendicularity, coplanarity, pin width, pin length, etc. of various IC chips and electronic connectors. First, the CCD camera is used to shoot the picture of the connector plane in an environment with sufficient light, then the threshold segmentation is realized using image processing technology, the projection positioning is realized by counting the changes of the pixel points of the rows and columns, the position of the PIN is determined according to the coordinate position, and finally the distance between the PINs is calculated using the Euclidean formula to determine the positional error data of the PINs.

[0038] The positional error data refers to the angle value of the horizontal offset of the PINs on the surface of the connector. A negative value indicates a leftward offset, and a positive value indicates a rightward offset. The larger the value, the greater the PIN offset error, which directly reflects the quality of the connector. This data is calculated by the CCD detection software and stored in the industrial computer equipment. In the positional error data of the connector, the first row of data is the deviation data of the first row of pins, the second row of data is the data of the second row of pins, the third and fourth rows represent the upper specification limit USL and the lower specification limit LSL of the first row of pins, and the fifth and sixth rows of data represent the upper specification limit USL and the lower specification limit LSL of the second row of pins. The data used in the present application is the error data of the first row and the specification data of the third and fourth rows.

[0039] Process Capability Index (CPK) is a parameter that objectively exists in the dispersion of the production process, and is a method that can represent the level of product quality. The larger the value, the better the product quality, and the higher the process capability. The CPK can be calculated by the CPK calculation formula, wherein USL represents the upper specification limit, LSL represents the lower specification limit, is the average value of the positive location error data, and δ is a preset constant. By obtaining the above data, the CPK of the connector can be calculated to measure the quality level, and the calculation formula is shown as follows.

[0040]

[0041] In the production process of the automation equipment, the CPK of the product is not the larger the better, but should be within a suitable range, so as to avoid the waste of production equipment resources. Therefore, the CPK rating standard and processing principle must be formulated, and the conventional CPK rating evaluation and processing principle is shown in Table 1. When the CPK reaches 1.67, it indicates that the product quality is very good and meets the standard of the product yield. When the value exceeds this value, the equipment can adapt to the production speed at this time, and the production speed of the equipment can be improved to reduce the CPK of the product. When the industrial index CPK is lower than 1.33, it indicates that the number of defective products is relatively large, and the running speed of the equipment needs to be reduced to improve the CPK of the product.

[0043]

[0044] 1 Structure and function of intelligent speed regulation system

[0045] The structure of the intelligent speed regulation system is shown in Figure 1 , which has the function of automatically adjusting the speed of the connector production equipment to increase the yield value, and is composed of a connector production equipment, a CCD detection software, an intelligent speed regulation software and a PLC device. First, the connector production equipment is responsible for producing connectors, and then the CCD detection software analyzes and identifies the connector plane photos taken by the CCD industrial camera to extract the positive location error value data and generate an error data table file. Then, the optimal running speed value of the connector production equipment is calculated according to the positive location error data of the connector. Finally, the PLC device reads the speed value in the file of the industrial computer device to control the action of each mechanism in the connector production equipment to complete the speed regulation operation. The intelligent speed regulation software is the core of the intelligent speed regulation system, and the design process of the intelligent speed regulation software will be mainly described.

[0046] 2 Program design of intelligent speed regulation software

[0047] The basis of the intelligent speed regulation software is the calculation of the CPK, and the core is the design of the speed regulation strategy module. This section will mainly describe the calculation method of the CPK and the design scheme of the intelligent speed regulation strategy to realize the functions of real-time monitoring of the CPK, simulation speed regulation, query of historical data and the like. The software function framework of the intelligent speed regulation system is shown in Figure 2 .

[0048] 2.1 Design of CPK calculation module

[0049] The computing process capability index CPK is the basis of the intelligent speed regulation system, because the quality standard of the product cannot be measured only by the positive positioning error data provided by the CCD detection software. Therefore, the CPK computing formula is used to calculate the process capability index CPK by taking the positive positioning error data of the connector as the input, to represent the quality standard thereof. The execution flow of the CPK computing module is shown in Figure 3

[0050] (1) Reading the folder file. When the program starts to execute, the folder path where the positive positioning error data is located and all error folders in the folder are read, and it is judged whether the two table files of “end surface” and “back surface” exist in the error folder. If one of them is missing, the error file is excluded, and the next error folder is read.

[0051] (2) Obtaining the text content of the file. When the data of the error folder is correct, the PIN number in the table file is read. When 4<PIN<16, the error data, LSL, USL and other data in the “end surface” table are read, otherwise the data in the “back surface” table are read, and it is judged whether the error data in the table exists or the PIN number or data format is incorrect.

[0052] (3) Computing the process capability index CPK. When the error data, LSL and USL in the table are obtained, the CPK of the connector is calculated according to the computing formula.

[0053] 2.2 Intelligent speed regulation strategy design

[0054] The intelligent speed regulation strategy is the core of the intelligent speed regulation software, which is composed of the speed regulation table and the CPK level evaluation table. In this section, the speed regulation table and the CPK level evaluation table suitable for the system are designed respectively by referring to the CPK level evaluation table and the processing principle in Table 1.

[0055] 1. Speed regulation table design

[0056] The most important thing in the design of the speed regulation strategy module is the design of the speed regulation table, which determines whether the connector production equipment can run stably. When the connector production equipment can be regulated according to the strategy of the speed regulation table A within the specified time, until the CPK is within the limited range and tends to be stable, the strategy of the speed regulation table B can be referred to for regulation. When the speed regulation C collects enough reference data, the subsequent system directly uses the strategy of the speed regulation table C to start regulation. The detailed speed regulation strategies of the three speed regulation tables designed in the application are shown in Table 2.

[0057] Table 2 Detailed explanation of the speed regulation table

[0058]

[0059] ​Because the quality of the connector is poor when the equipment is accelerated too fast, and the production efficiency is reduced or the machine is crashed when the equipment is accelerated too slow, the best acceleration value of the speed regulation table A is 200 and the best deceleration value is 500 according to the test scheme and results shown in Table 3, which meets the best speed regulation production state of the connector production equipment.

[0060] Table 3: Speed regulation test scheme and results

[0061]

[0062] 2. CPK level evaluation table design

[0063] In the production process of the automatic equipment, the quality standard of the product meets the trend of normal distribution, and the CPK has no great trend change, so the CPK level evaluation table only needs to select the most basic three ranges, the minimum CPK threshold value is set to 1.33, and the maximum CPK threshold value is set to 1.67, and the CPK level evaluation table is made on this basis, and a 0.1 error range is reserved as a buffer for equipment speed regulation, and the specific description is shown in Table 4.

[0064] Table 4: Level evaluation table description

[0065]

[0066] 3. Speed regulation strategy program design

[0067] On the basis of the design of the speed regulation table and the CPK level evaluation table, the speed regulation strategy program is designed to make the connector production equipment run according to the speed value in the speed regulation table, and the execution flow is shown in Figure 4 .

[0068] (1) CPK range judgment. When the CPK is in the set range, it means that the quality of the connector is good, and the speed regulation table can not be referred to for speed regulation, and the equipment still runs at the previous speed; when the CPK is greater than 1.67, the speed is accelerated according to the strategy of the speed regulation table A with a speed value of 200, if the next CPK value is still higher than 1.67, the speed is regulated according to the speed value of 400, and the highest acceleration value can reach 800; when the CPK is less than 1.32, the speed is decelerated according to the speed regulation table A with a speed value of 500, until the CPK is higher than 1.32, to ensure the quality of the subsequent production of the connector.

[0069] (2) Speed table judgment. When the speed regulation strategy program running time exceeds 24 hours, in order to speed up the calculation of the speed regulation value, the subsequent speed regulation can directly calculate the speed regulation value of the device by comparing the starting CPK, CPK difference, device speed increase value and other values in the strategy of speed table C; when the program time does not reach the specified time, it is judged whether the CPK is within the set specified range, if it is within the range and the number of speed regulation judgments also reaches 3 times, then the speed regulation is carried out according to the strategy of speed table B. Otherwise, the speed regulation is carried out according to the strategy of speed table A.

[0070] 2.3 System interface and function design

[0071] In order to enable users to intuitively monitor the CPK value and the change trend of the device speed, on the basis of realizing intelligent speed regulation, the system designs the interfaces of CPK real-time monitoring, analog simulation speed regulation, system parameter setting, historical data query and the like, and simultaneously adds the function of interface translation according to the requirements.

[0072] 1. CPK real-time monitoring interface

[0073] The CPK real-time monitoring interface is the display state of the intelligent speed regulation software, mainly including three parts, which are the device information status bar, the CPK real-time data bar and the speed real-time data bar. The device information status bar is used for displaying the pin number value, the current device speed value, the CPK value and the comprehensive improvement efficiency and the like data for the user to view in real time. As shown in Figure 5 , the CPK real-time data bar and the speed real-time bar are updated at a time interval of 13s, and their change trends are displayed in the form of a line graph, so as to facilitate the user to observe in time.

[0074] 2. Analog simulation speed regulation interface

[0075] This interface can facilitate the speed regulation test of the connector production device to judge whether the error data is correct. The analog simulation speed regulation interface mainly includes three parts, which are analog simulation test, PIN test and CPK test calculation, and the test result of the analog simulation speed regulation interface is shown in Figure 6 .

[0076] (1) Analog simulation test. Only by inputting the PIN number of the connector produced by the connector production device, the real CPK value, the current device speed, the self-set basic value CPK and the CPK error precision value in the analog simulation speed regulation interface, the simulation change trend of the current device speed value can be tested. In the face of different connector production devices in the factory, the parameter values of the speed regulation table can be quickly found, and the test time is saved.

[0077] (2) PIN needle test. The connector production equipment will produce different batches of connectors, which will have different PIN needle numbers. In order to test the quality level of the current connector produced by different equipment, only the PIN needle number and the file path of the error data need to be input in this interface, and the CPK value of the current error file can be calculated.

[0078] (3) CPK test. Select the file path of the error data for CPK value calculation.

[0079] 3. System parameter setting interface

[0080] The system parameter setting interface, as shown in Figure 7 , is used to set the basic CPK value, CPK threshold value, speed adjustment interval, CPK error precision, data deletion time interval, equipment speed-up value and speed-down value, etc. The parameters can be directly modified according to the different conditions of each connector production equipment. At the same time, in order to prevent too many positive degree error files from affecting the speed of the software reading table, a button is set below the interface to delete error files within 2 hours.

[0081] 4. Historical data query interface

[0082] The historical data page includes CPK historical data column and speed adjustment table column. The user selects the time range for query, and then clicks the query button. The comprehensive CPK value and the current speed value can be queried in the CPK historical data column, and the speed before adjustment, the speed after adjustment, the adjustment mode and the yield growth rate can be queried in the speed adjustment table column.

[0083] 5. Translation interface function

[0084] The intelligent speed regulation system software interface is a Chinese interface. In order to meet the needs of users, the application adds a translation function in the setting interface. Only by clicking the translation button, the Chinese speed regulation software interface can be translated into an English software interface. The translated English interface is shown in Figure 8 .

[0085] 3. Intelligent speed regulation software test

[0086] The test of the intelligent speed regulation software mainly includes stability test and effectiveness test. The stability test is to test the length of time that the system can stably run, and the effectiveness test is to test whether the system can increase the yield of connectors.

[0087] 3.1 Stability test

[0088] After the system design is completed, stability test is carried out to observe whether the system crashes or not. When it is determined that the system can be stably operated, it is deployed to the industrial computer of the connector production equipment, combined with the PLC equipment, to start the speed regulation operation, and observe whether the connector production equipment will appear the phenomenon of machine collision. Table 5 is the actual test details, and the test results show that the system can be stably operated, and no machine collision phenomenon occurs.

[0089] Table 5 System Actual Test Details

[0090]

[0091] 3.2 Effectiveness Test

[0092] The effectiveness of the system refers to whether the output of the connector quantity is significantly improved under the premise that the intelligent speed regulation system is stably regulated. The output growth rate is equivalent to the speed value growth rate, which can be simulated by checking the speed growth rate of the historical data to simulate the output improvement value of the connector production equipment after speed regulation. The system sets the initial running speed value to 22000, and calculates the output increase value every two hours. Table 6 is the relevant data of the connector production equipment speed regulation on site. Through the content in the table, it can be found that the output growth rate of the connector production equipment is higher than 4.5%, and the test results meet the requirements of the system.
