[0046] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] Firstly, refer to the appendix Figure 1 This application provides a PCBA board barcode scanning and writing test method, including:

[0050] S1: Obtain the information on the identification codes corresponding to several PCBA single boards in the PCBA panel and assign them numbers to generate an identification code information set, wherein the identification code information set includes identification code information and identification code information numbers that match the identification code information;

[0051] S2: Map the identifier information number in the identifier information set to the PCBA board number of each PCBA board in the PCBA panel, and generate a PCBA board sequence set;

[0052] S3: Obtain the PCBA board whose number in the PCBA board sequence set matches the identification code information number, and record it as the PCBA board to be written;

[0053] S4: Write the identification code information that matches the identification code information number into the PCBA board to be written and perform a write test.

[0054] As described in step S1 above, the PCBA panel in this embodiment is formed by splicing together several PCBA single boards. In the actual PCBA board writing test process, employees can control the software platform or software tools of the computer terminal to send scanning instructions to the visual barcode scanner. The visual barcode scanner will then photograph and scan the identification codes affixed to each PCBA single board in the PCBA panel in the fixture according to the instructions. The identification code information carried in the identification code that needs to be written to the corresponding PCBA single board (the writing data that needs to be written to the corresponding coded PCBA single board for testing) will be numbered 12345... and a dataset will be generated.

[0055] As described in step S2 above, if the visual scanner identifies the identification code at position 1 and assigns it the code "1", then both the corresponding identification code information number and the PCBA board number are "1". Preferably, the identification code can be affixed to a specific location on the PCBA panel. When the identification code is a full-page document, the visual scanner will sequentially identify the identification code information from a predetermined direction along a predetermined order, generating a number containing the identification code information and its corresponding identifier. For example, it might perform a bow-shaped scan from the top left corner of the entire identification code to the right, sequentially assigning each identification code information number 12345... Then, the identification code information number is used to assign the PCBA board number... During the numbering process, a bow-shaped scan is performed starting from the top left corner of the PCBA panel and moving to the right. Each PCBA board on the panel is then assigned a number corresponding to the identification code information at the corresponding position on the overall identification code. For example, if the identification code information of the first identification code identified from the top left corner of the overall identification code is 1, then the number of the first PCBA board numbered from the top left corner of the corresponding PCBA panel is 'a'. If the identification code information of the second identification code identified from the top left corner of the overall identification code is 2, then the number of the second PCBA board numbered from the top left corner of the corresponding PCBA panel is 'b', and so on, to generate a PCBA board sequence set.

[0056] As described in steps S3-S4 above, after the PCBA board sequence set is generated, the identification code information needs to be written into the corresponding numbered PCBA board. Therefore, the cloud server can filter out the PCBA board sequence set whose number matches the identification code information number and write the corresponding identification code information into this PCBA board. Thus, it is possible to perform number writing tests on multiple PCBA boards in one operation, which can greatly improve testing efficiency.

[0057] In one embodiment, the step of mapping the identifier information number in the identifier information set to the PCBA board number of each PCBA board in the PCBA panel to generate a PCBA board sequence set includes:

[0058] The identification code information number in the identification code information set is mapped one-to-one to the PCBA board number of each PCBA board in the PCBA panel;

[0059] A PCBA board sequence set is generated based on the one-to-one mapping relationship between the identification code information number and the PCBA board number.

[0060] As described above, after generating the identification code information set, the cloud server will assign a one-to-one number to each PCBA board in the PCBA panel according to the encoding order of the identification codes in the identification code information set. The identification code information number is then matched with the PCBA board number of each PCBA board in the PCBA panel. That is, if the identification code information number of position 1 is "1", then the corresponding PCBA board number at position 1 will also be assigned "1". In this way, all PCBA boards are scanned and the information in each PCBA board is matched with the corresponding number to generate a PCBA board sequence set. This ensures that the identification code information number and the PCBA board in the PCBA board sequence set are in a one-to-one correspondence, preventing confusion.

[0061] In one embodiment, after the step of writing the identification code information to the PCBA board corresponding to the identification code number and performing a write test, the method further includes:

[0062] Obtain the write completion signal of all PCBA boards in the PCBA panel that have been written with the identification code information, and generate a complete write number set;

[0063] The completed write number set is compared with the identification code information set in the preset database. Identification code information in the identification code information set that does not match the completed write number set is marked as not written to the identification code information set. The identification code information set in the preset database includes all identification code information used in this write test.

[0064] Obtain the number corresponding to the identifier information not written into the identifier information set, and generate an unwritten number set.

[0065] As described above, after the identification code information is written to the PCBA board corresponding to the identification code number, the PCBA board will send a signal to the computer terminal. The computer terminal will then determine whether the identification code information has been written to the corresponding PCBA board based on the feedback signal. The test computer terminal can obtain all feedback signals and generate a write number set. The write number set contains all the identification code information and its corresponding code. The write number set is then compared with the identification code information set in the preset database. The preset database contains all the identification code information that needs to be written in this test. Identification code information that is not in the identification code information set in the preset database and its corresponding number are included to generate an unwritten number set, which is displayed in the software platform or software tool. Therefore, it is possible to intuitively observe which PCBA boards have been written and which have not.

[0066] In one embodiment, before the step of writing the identification code information matching the identification code information number into the PCBA board to be written and performing the write test, the method further includes:

[0067] The identification code information in the identification code information set and the identification code information number matching the identification code information are converted into data to generate data stream information, wherein the data stream information contains the identification code information and the identification code information number.

[0068] As mentioned above, given that most existing PC / computer terminals and module fixtures connect via single-board operation and word writing, while this application allows for writing to multiple PCBA boards at once, data conversion is required between the PC / computer terminal and the module fixture. The computer sends identification code information data to the module fixture via a TCP connection. The converted data stream still contains the write data to be written to the corresponding numbered PCBA board and the identification code information number corresponding to the PCBA board number. Therefore, a serial port server and conversion box can be added between the PC / computer terminal and the module fixture to convert the computer terminal's TCP into a TTL communication interface that the module fixture can receive. This allows the computer to transmit write data for multiple PCBA boards to the module fixture at once. By using a multi-pin connector on the TTL communication interface, multiple sets of identification code information can be transmitted simultaneously to the programming circuit in the module fixture, writing the multiple sets of identification code information to the corresponding numbered PCBA boards.

[0069] In one embodiment, the step of converting the identifier information in the identifier information set into data includes:

[0070] The identification code information in the identification code information set is converted into a first data stream, wherein the first data stream is an RS232 data stream;

[0071] The first data stream is converted into a second data stream, which is TTL data.

[0072] As described above, in the specific scenario of this embodiment, two conversions can be performed between the computer and the module fixture. The first conversion is that the computer terminal connects to a serial port server via TCP. Therefore, the serial port server can convert the TCP protocol data stream into an SR232 data interface for routing. Then, the conversion box converts the data stream output from the SR232 data interface into the output data stream of the TTL communication interface. By connecting to the programming circuit of the module fixture through a multi-pin connector, it is possible to perform writing tests on multiple PCBA boards simultaneously.

[0073] Secondly, referring to Figure 2This application also provides a PCBA board barcode scanning and writing test device, the device comprising:

[0074] The identification code information set generation module 100 is used to obtain the information on the identification codes corresponding to several PCBA single boards in the PCBA panel and number them to generate an identification code information set, wherein the identification code information set includes identification code information and identification code information number matching the identification code information.

[0075] PCBA board sequence set generation module 200 is used to map the identification code information number in the identification code information set to the PCBA board number of each PCBA board in the PCBA panel, and generate a PCBA board sequence set.

[0076] The PCBA board to be written generation module 300 is used to obtain the PCBA board whose number in the PCBA board sequence set matches the identification code information number, and denot it as the PCBA board to be written.

[0077] The write test module 400 is used to write the identification code information that matches the identification code information number into the PCBA board to be written and perform a write test.

[0078] In one embodiment, the PCBA single-board sequence set generation module 200 is further configured to:

[0079] The identification code information number in the identification code information set is mapped one-to-one to the PCBA board number of each PCBA board in the PCBA panel;

[0080] A PCBA board sequence set is generated based on the one-to-one mapping relationship between the identification code information number and the PCBA board number.

[0081] In one embodiment, the PCBA board barcode scanning and writing test device further includes a comparison module, which is used for:

[0082] Obtain the write completion signal of all PCBA boards in the PCBA panel that have been written with the identification code information, and generate a complete write number set;

[0083] The completed write number set is compared with the identification code information set in the preset database. Identification code information in the identification code information set that does not match the completed write number set is marked as not written to the identification code information set. The identification code information set in the preset database includes all identification code information used in this write test.

[0084] Obtain the number corresponding to the identifier information not written into the identifier information set, and generate an unwritten number set.

[0085] In one embodiment, the PCBA board barcode scanning and writing test device further includes a data conversion module, which is used for:

[0086] The identification code information in the identification code information set and the identification code information number matching the identification code information are converted into data to generate data stream information, wherein the data stream information contains the identification code information and the identification code information number.

[0087] In one embodiment, the data transformation module includes:

[0088] The first conversion module is used to convert the identification code information in the identification code information set into a first data stream, wherein the first data stream is an RS232 data stream;

[0089] The second conversion module is used to convert the first data stream into a second data stream, wherein the second data stream is TTL data.

[0090] Thirdly, referring to Figure 3 This application also provides a PCBA board barcode scanning and marking test system, including: a main control unit 10, a switch unit 20, a visual barcode scanning unit 30, a serial port server unit 40, a conversion box unit 50, and a module fixture unit 60. The main control unit 10 is connected to the switch unit 20, the switch unit 20 is connected to the visual barcode scanning unit 30 and the serial port server unit 40 respectively, the serial port server unit 40 is connected to the conversion box unit 50, and the conversion box unit 50 is connected to the module fixture unit 60; wherein, the visual barcode scanning unit 30 is used to scan the markings in the PCBA board. The identification code information is identified and sent to the main control unit 10. The main control unit 10 is also used to number the identification code information and transmit the identification code information to the module fixture unit 60 based on the switch unit 20, serial port server unit 40, and conversion box unit 50. The serial port server unit 40 is used to realize the interface conversion between the switch unit 20 and the conversion box unit 50. The conversion box unit 50 is used to realize the interface conversion between the serial port server unit 40 and the module fixture unit 60. The module fixture unit 60 is used to write the identification code information into the PCBA panel.

[0091] In one embodiment, the PCBA board barcode scanning and writing test system further includes a factory server unit 70, which is connected to the switch unit 20 and is used to store the work order number and production status of the module.

[0092] As described above, the PCBA board barcode scanning and coding test system provided in this embodiment includes: a main control unit 10, a switch unit 20, a vision scanning unit 30, a serial server unit 40, a conversion box unit 50, a module fixture unit 60, and a factory server unit 70. The main control unit 10 includes a computer, a microcomputer, etc., and is equipped with software tools and a platform for controlling PCBA board module production. The switch unit 20 can provide a dedicated electrical signal path for any two network nodes connected to the switch unit 20. That is, during the production process, when an employee operates the software in the main control unit 10 to generate a command, it can be transmitted through the switch unit 20 to other devices connected to the switch unit 20. In this embodiment, both the visual scanning unit 30 and the serial server unit 40 are connected to the switch unit 20. Therefore, the serial server unit 40 is a 32-interface serial server. The serial server provides a serial-to-network function, converting RS-232 / 485 / 422 serial ports into TCP / IP protocol network interfaces, enabling bidirectional transparent data transmission between the RS-232 / 485 / 422 serial ports and the TCP / IP protocol network interface. That is, the data stream from the main control unit 10, after passing through the serial server unit 40, can output 32 SR232 data interfaces, which are then connected to the 32-interface conversion box unit 50 via 32 RJ45 adapter cables. The conversion box unit 50 is a communication interface signal conversion device. The device converts RS232 communication interface signals into TTL communication interface output data, which is then connected to the module fixture unit 60 via a 100-pin adapter cable. The module fixture unit 60 is equipped with multiple sets of fixtures for connecting and fixing multiple PCBA boards for testing and writing. During production, employees operate the main control unit 10, which sends operation commands to the vision scanning unit 30 via a TCP network connection to scan the QR codes on multiple PCBA boards installed in the module fixture unit 60. The scanned QR code information is numbered, arranged, and uploaded to the software within the main control unit 10. The software tool platform in the main control unit 10 receives the corresponding QR code information and then... The QR code information data is sent to the serial port server unit 40 with a 32-interface via a TCP connection. The serial port server unit 40 outputs 32 SR232 data interfaces, which are connected to the 32-interface conversion box unit 50 via 32 RJ45 adapter cables. The conversion box unit 50 converts the RS232 communication interface signal to the TTL communication interface output data, and then connects to the module fixture unit 60 via a 100-pin adapter cable. The module fixture unit 60 writes the QR code information data to the corresponding numbered PCBA board for testing. Therefore, 32 groups of PCBA boards can be set up at the same time in the module fixture unit 60, and the writing test of 32 groups of PCBA boards can be achieved in one operation, which can improve the productivity of employees.

[0093] It should be noted that the serial server unit 40 and the conversion box unit 50 used in this embodiment both have 32 interfaces. This is not a limitation. In actual use, the serial server unit 40 and the conversion box unit 50 with more or fewer interfaces can be selected according to actual production needs.

[0094] A factory server unit 70 is set up in the PCBA board barcode scanning and writing test device. The factory server unit 70 is equipped with a storage medium. During the production process, the steps performed by the main control unit 10, the vision scanning unit 30, the serial port server unit 40, the conversion box unit 50 and the module fixture unit 60, as well as the corresponding production status or test data such as work order number, production time and all identification code information, can be transmitted to the factory server unit 70 through the switch unit 20 for recording and storage, so as to facilitate future inspection.

[0095] Reference Figures 4 to 9 In one embodiment, the module fixture unit 60 is provided with a PCBA board scanning and writing test circuit, which includes: a power supply circuit 1, a state switching circuit 2, a serial port J1, a serial port J2, a serial port J3, and several writing circuits 3.

[0096] The power supply circuit 1 includes capacitor C67, capacitor C68, resistor R162, and chip U33. The first end of capacitor C68 and the power input pin VIN of chip U33 are connected to an external power supply. The second end of capacitor C68 is grounded. The power input pin VIN of chip U33 is also connected to the chip select pin CE of chip U33 and the first end of resistor R162.
