[0036] In this embodiment, an insertion loss test method is provided. Figure 2 is a flow chart of an insertion loss test method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0037] Step S202, in response to the import instruction, importing one or more stacking files of printed circuit boards into a stacking data management unit, wherein the stacking files include stacking data of the printed circuit boards;

[0038] The stackup data may be key data in the design of a printed circuit board (PCB), i.e., the benchmark data necessary for an insertion loss test. The stackup data may be set according to actual needs, such as the stackup, impedance, line width, line spacing, test frequency, and description of the test standard of an insertion loss impedance coupon; the stackup file may be a file for recording stackup data, wherein the stackup data may be recorded in a table; the stackup data management unit may be a tool for managing stackup data in an insertion loss test client of a printed circuit board. By importing a stackup file, the stackup data may be stored in the stackup data management unit, thereby helping users to manage and browse the stackup data of the PCB, allowing users to quickly view and compare different versions of stackup data, so as to better perform insertion loss testing and optimize design. At the same time, data analysis and reporting functions are provided to help users better understand and utilize stackup data.

[0039] Step S204, in response to an insertion loss test instruction for a first printed circuit board, reading coding information of the first printed circuit board, and parsing first stacking data of the first printed circuit board from the coding information;

[0040] The above-mentioned coded information can be a storage method for storing detailed information of the PCB, and the coded information can be a barcode, or a two-dimensional code, etc.; the above-mentioned first stacked data can be the original information of the PCB, that is, the detailed information of the coupon to be tested. In this embodiment, taking the two-dimensional code as an example, by parsing the coded information, the detailed information of the coupon to be tested on the PCB can be obtained, such as the PCB material number, plate material, production cycle, etc. By recording the original information of the PCB in the two-dimensional code, the detailed information of the PCB can be traced and managed, which helps enterprises monitor and manage the production process of the PCB and improve production efficiency and product quality.

[0041] Specifically, in response to a manual insertion loss test instruction for the first printed circuit board, the coded information of the first printed circuit board captured by the first image acquisition device is read, wherein the target object holds the first image acquisition device to capture the coded information of the first printed circuit board, and the insertion loss test instruction includes the manual insertion loss test instruction; or, in response to an automatic insertion loss test instruction for the first printed circuit board, the robot arm is controlled to move the second image acquisition device to the target position of the first printed circuit board, and the coded information at the target position is read, wherein the manual insertion loss test instruction includes the automatic insertion loss test instruction.

[0042] Step S206, matching the overlay data in the data management unit with the first overlay data, and in the case where the data management unit matches the first overlay data, determining the overlay file in the data management unit that matches the first overlay data as the target overlay file;

[0043] In this embodiment, the original information of the QR code is parsed by parsing rules, and then the detailed information of the Coupon to be tested is obtained, including the PCB material number, plate material, production cycle, etc., and then the stacking data is matched in the stacking management unit according to the detailed information of the Coupon to be tested, and the stacking file matching the first stacking data is obtained to obtain the target stacking file, and then the stacking, impedance, line width, line spacing, test frequency and test standard information of the Coupon to be tested are obtained, so as to obtain the complete test information of the Coupon, and the insertion loss test is performed according to this information. The original information obtained by parsing the QR code is matched with the stacking data, so as to obtain complete test information, avoid manual filling and selection of test information, increase the degree of automation of the insertion loss test, reduce the situation of human-induced errors, and improve the efficiency and reliability of the insertion loss test. At the same time, in the embodiment, the insertion loss test can only be performed when the stacking data is matched, which ensures the integrity of the test data and further improves the accuracy of the insertion loss test.

[0044] Optionally, in response to a manual insertion loss test instruction for the first printed circuit board, after reading the coded information of the first printed circuit board acquired by the first image acquisition device, an insertion loss test is performed on the first printed circuit board when the data management unit matches the first stack data, including: outputting a first prompt message, wherein the first prompt message is used to prompt the target object to move the test probe of the tester to the test point of the first printed circuit board, so as to perform the insertion loss test on the first printed circuit board through the tester; after the tester completes the insertion loss test on the first printed circuit board, obtaining the insertion loss test result.

[0045] The above-mentioned tester can be a network analyzer, etc. The tester can be managed and controlled through the insertion loss test client of the printed circuit board. The tester is controlled by the client to perform the insertion loss test. During manual testing, the user (target object) only needs to move the test probe of the tester to the test point of the printed circuit board, and the tester can be controlled by the program to perform the insertion loss test on the printed circuit board, which reduces the errors and test time caused by manual testing and greatly improves the test efficiency.

[0046] Optionally, in response to an automatic insertion loss test instruction for the first printed circuit board, the robot arm is controlled to move the second image acquisition device to a target position of the first printed circuit board, and after reading the coded information at the target position, an insertion loss test is performed on the first printed circuit board when the data management unit matches the first stack data, including: controlling the robot arm to move a test probe of the tester to a test point on the first printed circuit board, and performing the insertion loss test on the first printed circuit board by the tester; after the tester completes the insertion loss test on the first printed circuit board, obtaining robot arm parameters and insertion loss test results, wherein the robot arm parameters include a duration for the robot arm to move to the test point and a pressure value between the test probe of the tester and the test point.

[0047] The above-mentioned robot arm parameters can be equipment parameters of the robot arm during the operation process, such as the time it takes for the robot arm to move to the point to be tested, the pressure value between the test probe of the tester and the point to be tested, etc.; by using the robot arm to perform insertion loss test on the PCB, human intervention can be completely eliminated, and the user only needs to control each link of the test through the program to perform the test, thereby improving the efficiency and accuracy of the test. At the same time, by obtaining the time it takes for the robot arm to move to the point to be tested, the pressure value between the test probe of the tester and the point to be tested, and the test result of the insertion loss test, the equipment parameters of the robot arm can be optimized and adjusted, thereby avoiding the influence of the wear of the mechanical structure of the robot arm after a period of operation on the accuracy of the insertion loss test, thereby improving the adaptability of the robot arm.

[0048] Step S208: Perform an insertion loss test on the first printed circuit board using the stacking data in the target stacking file and the first stacking data.

[0049] Through the above steps, the stacking file is imported through the stacking data management unit, the stacking data is stored and managed, and the original data of the printed circuit board is stored through the coding information to manage the detailed information of the printed circuit board. Then, when performing the insertion loss test, the original data of the printed circuit board is obtained by parsing the coding information on the printed circuit board, and the corresponding stacking data is matched according to the original data, so as to obtain complete test data, and perform the insertion loss test on the printed circuit board, thereby avoiding manual filling and selection of test information, increasing the automation of the insertion loss test, reducing the situation of human-induced errors, and improving the efficiency and reliability of the insertion loss test. At the same time, since the insertion loss test can only be performed when the stacking data is matched, the integrity of the test data is guaranteed, and the accuracy of the insertion loss test is further improved. The problem of low efficiency of insertion loss testing in related technologies is solved, and the efficiency of insertion loss testing is improved.

[0050] In addition, by matching the first stack data with the stack data in the stack data management unit, the information contained in the first stack data of the PCB is verified, and the insertion loss test is performed on the PCB only when the match is successful, thereby avoiding errors and waste caused by direct testing without verifying the PCB information, and improving the reliability and efficiency of the insertion loss test.

[0051] The execution subject of the above steps may be a server, a terminal, etc., but is not limited thereto.

[0052] As an optional embodiment, after obtaining the robot arm parameters from the robot arm, the device parameters of the robot arm are adjusted according to the robot arm parameters, including: when the robot arm parameters indicate that the time length for the robot arm to move to the point to be measured is greater than a first time length threshold, controlling the robot arm to increase the moving speed within a preset moving range; or, when the robot arm parameters indicate that the time length for the robot arm to move to the point to be measured is less than a second time length threshold, controlling the robot arm to reduce the moving speed within a preset moving range, wherein the second time length threshold is less than the first time length threshold.

[0053] The above-mentioned first time threshold, second time threshold and preset movement range can be the optimal operating range of the robot arm, and the optimal operating range can be obtained by testing the standard Coupon; by automatically adjusting the equipment parameters within the preset movement range, the robot arm can maintain the best test accuracy, improve the adaptability of the robot arm and the accuracy of the test results of the insertion loss test.

[0054] As an optional embodiment, the method also includes: sending a first transmission instruction to the robotic arm when one of the following conditions is met, and the first transmission instruction is used to instruct the robotic arm to transmit data of each moving part of the robotic arm: the moving speed of the robotic arm is adjusted to the maximum value in the preset moving range, and the time length for the robotic arm to move to the point to be measured is greater than the first time length threshold; the moving speed of the robotic arm is adjusted to the minimum value in the preset moving range, and the time length for the robotic arm to move to the point to be measured is less than the second time length threshold.

[0055] The above-mentioned first transmission instruction can be an instruction for instructing the robot arm to transmit the parameters of the mobile equipment (that is, the data of each moving component) during the operation. Through the first transmission instruction, the robot arm outputs the data of each moving component during the operation; when the moving speed of the robot arm is adjusted to the maximum value in the preset moving range, and the time length of the robot arm moving to the point to be measured is greater than the first time length threshold, it means that the moving speed of the robot arm has reached the upper limit, but at this time the moving time length of the robot arm is still greater than the first time threshold (that is, the robot arm moves too slowly). At this time, it is necessary to send the first transmission instruction to the robot arm to instruct the robot arm to output the data of each moving component; or, when the moving speed of the robot arm is adjusted to the minimum value in the preset moving range, and the time length of the robot arm moving to the point to be measured is greater than the first time length threshold. When the length of the movement of the robot arm is less than the second time threshold, it means that the movement speed of the robot has reached the lower limit, but the movement time of the robot arm is still less than the second time threshold (that is, the robot arm moves too fast). At this time, it is necessary to send a first transmission instruction to the robot arm to instruct the robot arm to output the data of each moving part; by sending the first transmission instruction and outputting the data of each moving part of the robot arm according to the first transmission instruction, the user can obtain the data of the robot arm even when the robot arm cannot meet the optimal operating range, and perform a health check and evaluation of the robot arm based on the data of the robot arm, so as to promptly discover and solve the problems of the robot arm, ensure the normal operation and safety of the robot arm, and better manage and maintain the robot arm, extend the service life of the robot arm, and improve production efficiency and quality.

[0056] As an optional embodiment, after sending a first transmission instruction to the robotic arm, the method further includes: receiving data of each moving component of the robotic arm, and comparing them with standard data of each moving component to obtain a first comparison result of the mobile component; when the first comparison result indicates that the data of the target moving component of the robotic arm is inconsistent with the standard data, outputting a second prompt message, wherein the second prompt message is used to indicate that the target moving component has a fault.

[0057] The above-mentioned standard data can be the parameters of each moving part of the robotic arm specified in the official manual of the robotic arm. The state of the robotic arm is judged by comparing with the standard data. When the parameters of the moving parts of the robotic arm are inconsistent with the standard data, a second prompt message is output to indicate that the moving parts of the robotic arm have failed, and the user is reminded to repair the robotic arm in time, thereby avoiding further damage to the robotic arm and improving the maintainability of the robotic arm.

[0058] As an optional embodiment, after obtaining the robotic arm parameters from the robotic arm, adjusting the equipment parameters of the robotic arm according to the robotic arm parameters also includes: when the robotic arm parameters indicate that the pressure value between the test probe of the tester and the point to be tested is greater than a first pressure threshold, raising the robotic arm according to a preset lifting range; when the robotic arm parameters indicate that the pressure value between the test probe of the tester and the point to be tested is less than a second pressure threshold, lowering the robotic arm according to a preset lifting range, wherein the second pressure threshold is less than the first pressure threshold.

[0059] The first pressure threshold, the second pressure threshold and the preset lifting range can be the optimal operating range of the robot arm, and the optimal operating range can be obtained by testing the standard Coupon; by automatically adjusting the equipment parameters within the preset lifting range, the robot arm can maintain the best test accuracy, improve the adaptability of the robot arm and the accuracy of the test results of the insertion loss test.

[0060] As an optional embodiment, the method also includes: sending a second transmission instruction to the robotic arm when one of the following conditions is met, the second transmission instruction is used to instruct the robotic arm to transmit data of each lifting component of the robotic arm: the robotic arm is raised to the maximum value in the preset lifting range, and the pressure value between the test probe of the tester and the point to be tested is greater than the first pressure threshold; the robotic arm is lowered to the minimum value in the preset lifting range, and the pressure value between the test probe of the tester and the point to be tested is less than the second pressure threshold.

[0061] The above-mentioned second transmission instruction can be an instruction for instructing the lifting equipment parameters (i.e., the data of each lifting component) during the transmission operation of the robot arm. Through the second transmission instruction, the robot arm outputs the data of each lifting component during the operation accordingly; when the lifting height of the robot arm is adjusted to the maximum value in the preset lifting range, and the pressure value between the test probe of the tester and the point to be tested is greater than the first pressure threshold, it means that the lifting height of the robot arm has reached the upper limit, but at this time the pressure value between the test probe of the tester and the point to be tested is still greater than the first pressure threshold (i.e., the pressure value between the test probe of the tester and the point to be tested when the robot arm moves is too large). At this time, it is necessary to send a second transmission instruction to the robot arm to instruct the robot arm to output the data of each lifting component; or, when the lifting height of the robot arm is adjusted to the minimum value in the preset lifting range, and the test probe of the tester is When the pressure value between is less than the second pressure threshold, it means that the lifting height of the robotic arm has reached the lower limit, but at this time the pressure value between the test probe of the tester and the point to be tested is still less than the second pressure threshold (that is, the pressure value between the test probe of the robotic arm movement tester and the point to be tested is too small). At this time, it is necessary to send a second transmission instruction to the robotic arm to instruct the robotic arm to output the data of each lifting component; by sending the second transmission instruction and outputting the data of each lifting component of the robotic arm according to the second transmission instruction, the user can obtain the data of the robotic arm even when the robotic arm cannot meet the optimal operating range, and perform a health check and evaluation of the robotic arm based on the data of the robotic arm, so as to promptly discover and solve the problems of the robotic arm, ensure the normal operation and safety of the robotic arm, and at the same time better manage and maintain the robotic arm, extend the service life of the robotic arm, and improve production efficiency and quality.

[0062] As an optional embodiment, after sending a second transmission instruction to the robotic arm, the method also includes: receiving data of each lifting component of the robotic arm, and comparing them with standard data of each lifting component to obtain a second comparison result of the lifting component; when the second comparison result indicates that the data of the target lifting component of the robotic arm is inconsistent with the standard data, outputting a third prompt message, and the third prompt message is used to indicate that the target lifting component has a fault.

[0063] The above-mentioned standard data can be the parameters of each lifting component of the robotic arm specified in the official manual of the robotic arm. The state of the robotic arm is judged by comparing the standard data.
