[0038] like Figure 3 As shown, Figure 3 A schematic flow chart of a single board automated testing method provided by an embodiment of the present invention. The single board automated testing method provided by an embodiment of the present invention is applied to any embodiment of the aforementioned single board automated testing device, and the method comprises steps S11 to S14.

[0039] S11. The optical sensor component detects the online status of the tooling fixture in real time, and transmits the online status to the host computer.

[0040] In this embodiment, the optical sensor component detects the online status of the jig in real time and transmits the online status to the host computer, so that the host computer can monitor in real time whether the jig is moved or replaced in the middle of the process through the online status. By using the optical sensor component to realize online detection of jigs, it is possible to prevent jigs from being replaced at will and prevent relevant personnel from replacing jigs privately, resulting in production abnormalities.

[0041] S12, the scanning component scans the fixture code on the tooling fixture and the board code on the PCBA board to be tested, and transmits the scanned fixture code and the board code to the host computer.

[0042] In this embodiment, relevant personnel operate the scanning component to scan the fixture code on the tooling fixture and the board code on the PCBA board to be tested. The scanning component transmits the scanned fixture code and board code to the host computer, so that the host computer can obtain the corresponding test program from the remote server through the fixture code and board code, thereby realizing automatic acquisition of the test program. The test program does not require manual operation and setting, thereby preventing the test program from being modified without permission.

[0043] S13, the host computer controls the lifting and driving assembly to move downward in response to the downward pressure instruction, so that the lifting and driving assembly drives the test probe on the tooling fixture to contact the PCBA board to be tested.

[0044] In this embodiment, the push command is triggered by a relevant person, for example, the relevant person triggers the push command by pressing a relevant button. In response to the push command, the host computer controls the lifting drive assembly to move downward, so that the lifting drive assembly drives the test probe on the tooling fixture to contact the PCBA board to be tested, so that when the PCBA board to be tested is tested later, the test instrument can realize signal transmission with the PCBA board to be tested through the test probe on the tooling fixture.

[0045] S14, the host computer obtains the corresponding test program from the remote server according to the fixture code and the single board code, and controls the test instrument according to the test program and the online status to obtain test data.

[0046] In this embodiment, the host computer obtains the corresponding test program from the remote server according to the fixture code and the single board code, and then controls the action of the test instrument according to the test program and the online status to automatically test the PCBA single board to be tested, thereby obtaining test data. The host computer automatically obtains the test program and monitors the online status of the tooling fixture in real time, which can prevent the test program from being modified privately and the tooling fixture from being replaced at will, and the test process is automatically executed, which reduces the test time and improves the test efficiency.

[0047] In one embodiment, the test data includes test abnormality data and item test data corresponding to the test program; step S14 includes:

[0048] The host computer obtains the corresponding test program and target fixture code from the remote server according to the single board code;

[0049] If the host computer determines that the test program is a non-empty set, it determines whether the fixture code is consistent with the target fixture code;

[0050] If the host computer determines that the fixture code is consistent with the target fixture code, the host computer controls the test instrument to provide a corresponding test signal to the PCBA board to be tested and tests the PCBA board to be tested according to the test program;

[0051] If the host computer determines that the online state has changed or detects a test failure, it controls the test instrument to stop testing the PCBA board to be tested and obtains the test abnormality data;

[0052] If the host computer determines that the online status has not changed and no test failure is detected, the project test data is obtained.

[0053] In this embodiment, after receiving the single board code scanned by the scanning component, the host computer will obtain the corresponding test program and target fixture code from the remote server according to the single board code. If the host computer determines that the test program is a non-empty set, it means that the obtained test program exists, and then it is determined whether the fixture code is consistent with the target fixture code, because each set of tooling and fixtures has a unique code, and the tooling and fixtures and the relevant codes on the corresponding PCBA single board to be tested are bound one by one in the remote tooling database in the remote server. By determining whether the fixture code is consistent with the target fixture code, it can be detected whether the tooling and fixture corresponding to the fixture code can be used to test the PCBA single board to be tested corresponding to the single board code. If the host computer determines that the fixture code is consistent with the target fixture code, it means that the tooling and fixture used is correct, and the current tooling and fixture can be used to test the PCBA single board to be tested. The host computer controls the action of the test instrument according to the test program, so that the test instrument provides the corresponding test signal to the PCBA single board to be tested and tests the PCBA single board to be tested, thereby starting to automatically execute the test items corresponding to the test program. During the process of the test instrument testing the PCBA board to be tested, if the host computer determines that the online state has changed or a test fault has been detected, the host computer controls the test instrument to stop testing the PCBA board to be tested and obtains test abnormality data; wherein, the change in the online state indicates that the online state of the tooling fixture is abnormal, such as the tooling fixture is moved or replaced in the middle; the detection of a test fault indicates that a defective item of the PCBA board to be tested is tested, and the PCBA board to be tested is a defective product. During the process of the test instrument testing the PCBA board to be tested, if the host computer determines that the online state has not changed and no test fault has been detected, the host computer obtains the project test data corresponding to the test program, that is, obtains the data tested after executing the test items corresponding to the test program; wherein, the change in the online state indicates that the online state of the tooling fixture is normal; the failure to detect a test fault indicates that no defective item of the PCBA board to be tested is tested, and the PCBA board to be tested is a good product.

[0054] In one embodiment, if the host computer determines that the test program is a non-empty set, after determining whether the fixture code is consistent with the target fixture code, the method further includes:

[0055] If the host computer determines that the fixture code is inconsistent with the target fixture code, it generates and displays a fixture error prompt message.

[0056] In this embodiment, if the host computer determines that the fixture code is inconsistent with the target fixture code, it means that the tooling fixture used is incorrect, and the current tooling fixture cannot be used to test the PCBA board to be tested. The host computer generates and displays a fixture error prompt message to prompt relevant personnel to replace the correct tooling fixture in time.

[0057] In one embodiment, after the host computer obtains the corresponding test program and target fixture code from the remote server according to the single board code, it also includes:

[0058] If the host computer determines that the test program is an empty set, it updates the single board code using the new single board code re-scanned by the scanning component, and returns to execute the step of the host computer obtaining the corresponding test program and target fixture code from the remote server according to the single board code.

[0059] In this embodiment, if the host computer determines that the test program is an empty set, it means that the acquired test program does not exist, and it may be that the relevant code on the PCBA single board to be tested is scanned incorrectly due to an operation error, and the correct single board code on the PCBA single board to be tested needs to be re-scanned by the scanning component. The host computer updates the single board code using the new single board code re-scanned by the scanning component, and returns to execute the step of the host computer acquiring the corresponding test program and target fixture code from the remote server according to the single board code, so as to obtain the test program and target fixture code bound to the correct single board code on the PCBA single board to be tested from the remote server.

[0060] In one embodiment, after step S14, the method further includes:

[0061] The host computer displays the test data and stores the test data in the remote server.

[0062] In this embodiment, after obtaining the test data, the host computer will display the test data so that relevant personnel can observe the test data in time. At the same time, the host computer will also store the test data in the remote server, ensuring that all operations during the test can be recorded and traced, which is convenient for recording and abnormal analysis.

[0063] The single-board automated testing method provided by the embodiment of the present invention is applied to any embodiment of the aforementioned single-board automated testing device. The host computer obtains the corresponding test program from the remote server according to the fixture code and the single-board code, and controls the test instrument according to the test program and the online status to obtain test data, thereby realizing the automated testing of the PCBA single board. The test program does not require manual operation and setting, and the online status of the tooling and fixture can be monitored in real time, thereby preventing the test program from being modified privately and the tooling and fixture from being replaced at will, reducing manual operation links, reducing testing hours, and also improving testing efficiency and reducing production costs.
