[0048] The concept and the generated technical effects of the present application will be described below in conjunction with the embodiments, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative labor are within the scope of protection of the present application.

[0050] In the description of the embodiments of the present application, if "several" is referred to, it means more than one, if "multiple" is referred to, it means more than two, and if "greater than", "less than", "exceeding" is referred to, it should be understood as not including the number itself, if "and above", "and below", "and within" are referred to, it should be understood as including the number itself. If "first", "second" is referred to, it should be understood as distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.
[0051] Since the electronic manufacturing industry mainly performs electronic manufacturing, in which the function and stability of each PCB and PCBA need to be ensured in electronic manufacturing, the components on the PCB and PCBA need to be tested, and therefore the flying probe test equipment needs to be used to probe the test points on the PCB and PCBA, and since the probe needs to be frequently moved to the probing point during the flying probe test, the flying probe test needs to ensure the accuracy of the probing, and therefore how to improve the accuracy in the flying probe test is a problem to be solved at present.
[0052] Reference Figure 1, shows a flowchart of the flying probe motion control method in the embodiment of the application. The embodiment of the application includes but is not limited to step S100, step S200 and step S300.
[0053] Step S100: Obtain current test item information and next target test item information, the current test item information includes: a plurality of current test point coordinate information, a plurality of current probe identity information, and the target test item information includes: a plurality of target test point coordinate information, a plurality of target probe identity information.
[0054] It should be noted that the current test item information is the test item information currently executed, and the target test item information is the test item information of the next step after the current execution. The current test item information includes a plurality of current test point coordinate information and a plurality of current probe identity information, the current test point coordinate information is the coordinate information of the current probe test point currently executed, and the current probe identity information is the probe label currently executed. The target test item information includes a plurality of target test point coordinate information and a plurality of target probe identity information, the target test point coordinate information is the test point coordinate information of the next step, and the target probe identity information is the identity information of the probe needed to be used in the next step.
[0055] Step S200: Compare the plurality of current test point coordinate information and the plurality of target test point coordinate information, and compare the plurality of current probe identity information and the plurality of target probe identity information.
[0056] It should be noted that since the current test item information currently executed is the test information of a plurality of probes, and the target test item information is the test information of the probe needed to be used in the next step, if it is needed to judge whether the probe in the next step needs to be moved. Therefore, the plurality of current test point coordinate information and the plurality of target test point coordinate information are compared one by one, and the plurality of current probe identity information and the plurality of target probe identity information are compared one by one, to judge whether there is the same test point in the current execution test item and the next step test item, and to judge whether the same test point needs to continue to use the same probe, to determine whether to move the probe, and to reduce the test error caused by the multiple movements of the probe.
[0057] Step S300: According to the matching of the current test point coordinate information and the target test point coordinate information and the matching of the current probe identity information and the target probe identity information, control the current probe corresponding to the current probe identity information not to move.
[0058] It should be noted that if there are several current test point coordinate information and target test point coordinate information matching in the plurality of current test point coordinate information, and the current probe identity information corresponding to the current test point coordinate information matching the target test point coordinate information matches the target probe identity information, that is, there is a same test point and uses the same probe in the next step, the current probe identity information corresponding to the current probe is not moved to reduce the number of probe movements. Too much can improve the efficiency of probe piercing, reduce repeated piercing damage to the device, and reduce the error of piercing points caused by excessive piercing times.
[0059] In summary, by comparing the plurality of current test point coordinate information currently executed with the plurality of target test point coordinate information in the next step one by one, and comparing the plurality of current probe identity information currently executed with the plurality of target probe identity information in the next step one by one. If the current test point coordinate information matches the target test point coordinate information, and the current probe identity information corresponding to the matching current test point coordinate information matches the target probe identity information, the current test point coordinate information corresponding to the current probe is not moved to reduce the repeated movement and piercing of the probe. On the one hand, it can improve the efficiency of probe piercing to reduce excessive piercing damage to the device, and on the other hand, it can reduce the probability of piercing point error by reducing probe movement to improve the accuracy of piercing.
[0060] Please refer to Figure 2 In some embodiments of the present application, before step S100 is executed, the flying probe motion control method further includes but is not limited to steps S010 and S020.
[0061] Step S010: Obtain a preset collection step interval, and the preset collection step interval is an interval of a preset number of steps before and after the current test.
[0062] It should be noted that if the target test item information in the next step needs to be reacquired before each execution of the next probe test, the efficiency of the flying probe test will be affected, so the user generally defines the interval of the preset number of steps before and after the current test to determine the preset collection step interval according to the interval of the preset number of steps before and after the current test. For example, if the preset number of steps is 5 steps, the preset collection step interval is determined to be 5 steps before and after the current test.
[0063] Step S020: Collect a plurality of test item information corresponding to the preset collection step interval to obtain a test item information set.
[0064] It should be noted that by collecting a plurality of test item information in a preset collection step interval, and putting the plurality of test item information into a test item information set, and then comparing the test item information of the current step and the test item information of the next step, it is determined whether the current probe needs to be moved, so it is not necessary to obtain the target test item information every time, but only to directly call the target test item information of the next step from the test item information set. For example, if the preset collection step interval is the first 5 steps to the last 5 steps, the first 5 steps and the last 5 steps of the test item information of the current test item are obtained, and the 10 steps of the test item information are stored in the test item information set, and the current test item information and the target test item information are directly extracted from the test item information set.
[0065] Please refer to Figure 3 In some embodiments of the present application, step S100 can include but is not limited to step S110 and step S120.
[0066] Step S110: obtaining current test item information;
[0067] It should be noted that if the flying probe test is started, the current test item information is obtained, that is, the test item information of the current execution is obtained.
[0068] Step S120: obtaining the test item information of the next step from the test item information set according to the current test item information to obtain the target test item information.
[0069] It should be noted that since the test item information set includes the test item information of the first preset step and the last preset step of the current execution test item information, the test item information of the next step can be extracted from the test item information set as the target test item information after the current test item information is determined. If the next step test is performed after the test of the target test item information is completed, the target test item information is defined as the current test item information, and the next test item information is continuously obtained. For example, if the current execution step is the 5th step, and the test item information set stores the test item information of the 1st step to the 10th step, and the test item information of the 6th step is extracted from the test item information set as the target test item information.
[0070] Please refer to Figure 4 In some embodiments of the present application, the flying probe motion control method further comprises:
[0071] Step S410: obtaining the target probe corresponding to the target probe identity information according to the mismatch between the current test point coordinate information and the target test point coordinate information, and / or the mismatch between the current probe identity information and the target probe identity information.
[0072] It should be noted that, in the case that the current test point coordinate information and the target test point coordinate information in the current test item information do not match, although the current probe identity information corresponding to the current test point coordinate information and the target probe identity information match, the current probe also needs to be moved. Or, in the case that the current test point coordinate information and the target test point coordinate match, but the current probe identity information corresponding to the current test point coordinate information and the target probe identity information do not match, it indicates that the target probe is needed to be used to pierce again to the current test point coordinate information. Therefore, by obtaining the target probe corresponding to the target probe identity information, if the current test point coordinate information and the target test point coordinate information are the same, but the current probe identity information corresponding to the current test point coordinate information and the target probe identity information do not match, the target probe needs to be reacquired. If the current test point coordinate information and the target test point coordinate information do not match, but the current probe identity information corresponding to the current test point coordinate information and the target probe identity information match, the target probe obtained is the original probe. Wherein, the current probe identity information is the current probe ID, and the target probe identity information is the target probe ID.
[0073] Step S420: control the current probe to move back to the position corresponding to the preset original coordinate information, and move the target probe to the position corresponding to the target test point coordinate information.
[0074] It should be noted that, when the test points are different and / or the probes corresponding to the test points are also different, the corresponding probe currently executed needs to be moved back to the position corresponding to the preset original coordinate information, that is, the current probe needs to be moved back to the safe position, without affecting the piercing of the probe in the next step.
[0075] It should be noted that, for example, if the current test point coordinate information is (A1, B1), the target test point coordinate information is (A2, B2), the current probe ID is T1, and the target probe is T2, the target probe T2 is acquired, and the target probe T2 is pierced to (A2, B2). If the current test point coordinate information is (A1, B1), the target test point coordinate information is (A1, B1), the current probe ID is T1, and the target probe is T2, the target probe T2 is acquired, and the target probe T2 is pierced to (A1, B1). If the current test point coordinate information is (A1, B1), the target test point coordinate information is (A2, B2), the current probe ID is T1, and the target probe is T1, the target probe T1 is acquired, and is pierced to (A2, B2).
[0076] Please refer to Figure 5 In some embodiments of the present application, after step S420 is performed, the flying probe motion control method further comprises:
[0077] Step S510: acquire the current multiple test item information;
[0078] It should be noted that if it is needed to determine whether the flying probe test is completed, the current multiple tested item information needs to be acquired, and the multiple tested item information is accumulated tested item information.
[0079] Step S520: match the multiple tested item information and the preset test item table information one by one.
[0080] It should be noted that the preset test item table information is a preset test item table that needs to be tested, and therefore, the multiple tested item information and the test item information on the preset test item table information need to be matched one by one. Specifically, the tested item information is acquired as a test item serial number, and then the test item serial number and the test item serial number on the preset test item table information are matched one by one.
[0081] Step S530: if the multiple tested item information and the preset test table information are matched, control the current probe and the target probe to move to the position corresponding to the preset original coordinate information.
[0082] It should be noted that if the multiple tested item information and the preset test item table information are matched, it indicates that all the test items are tested, and therefore, the current probe and the target probe are controlled to move to the position corresponding to the preset original coordinate information, so as to return all the probes to the safe position. If the multiple tested item information and the preset test item table information are not completely matched, the test of the next test item information is continued.
[0083] Please refer to Figure 6 In some embodiments of the present application, the target test point coordinate information includes target X-axis coordinate information, target Y-axis coordinate information, and target Z-axis coordinate information. Step S420 can further include but is not limited to step S421, step S422, and step S423.
[0084] Step S421: control the current probe to move back to the position corresponding to the preset original coordinate information.
[0085] It should be noted that since the current test point and the next test point do not match, and / or the current probe and the next target probe do not match, the current probe needs to be moved back to the position corresponding to the preset original coordinate information, so as to reset the current probe that is not needed to the safe position. Although the current probe is still needed to be used or needs to be reset to the safe position, it is convenient to move according to the new target test point coordinate information, so as to reduce the error of the probe needle.
[0086] Step S422: move the target probe to the horizontal plane position corresponding to the target X-axis coordinate information and the target Y-axis coordinate information.
[0087] It should be noted that, since the target test point coordinate information includes target X-axis coordinate information, target Y-axis coordinate information and target Z-axis coordinate information, the target probe needs to be moved in the horizontal plane first.
[0088] Step S423: lifting the target probe from the horizontal plane position to the Z-axis position corresponding to the target Z-axis coordinate information.
[0089] It should be noted that, after the movement of the target probe in the horizontal plane is completed, the target probe is moved from the horizontal plane to the Z-axis position corresponding to the target Z-axis coordinate information, so that the movement of the target probe is more accurate, thereby improving the accuracy of the probe needle.
[0090] In summary, a preset collection step interval is obtained, and a plurality of test item information corresponding to the preset collection step interval is obtained to obtain a test item information set. When flying probe testing is performed, the current test item information currently executed is obtained, and the test item information of the next step is extracted from the test item information set as the target test item information according to the current test item information. The plurality of current probe identity information currently executed and the plurality of target probe identity information of the next step are compared one by one, if the current test point coordinate information and the target test point coordinate information match, and the current probe identity information corresponding to the matched current test point coordinate information and the target probe identity information match, the current probe corresponding to the current test point coordinate information is not moved, so as to reduce the repeated movement and needle of the probe, on the one hand, the efficiency of the probe needle can be improved, so as to reduce the damage of the device caused by too many needles, on the other hand, the movement of the probe is reduced to reduce the probability of error of the needle point, so as to improve the accuracy of the needle. The target probe corresponding to the target probe identity information is obtained, if the current test point coordinate information and the target test point coordinate information do not match, and / or the current test point coordinate information corresponding to the current probe identity information and the target probe identity information do not match. The target probe is controlled to move back to the position corresponding to the preset original coordinate information, the target probe is moved to the horizontal plane position corresponding to the target X-axis coordinate information and the target Y-axis coordinate information, and the target probe is moved from the horizontal plane to the Z-axis position corresponding to the target Z-axis coordinate information, so that the movement of the target probe is more accurate, thereby improving the accuracy of the probe needle.
