Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for testing insertion and extraction force provided by an embodiment of the present application, where the method for testing insertion and extraction force includes the following specific steps:
step S11: and selecting a corresponding jig according to the insertion and extraction force test item.
The jig is a tool for carpenters, ironmen, pincers, machines, electric controls and other handicrafts, and is mainly used as a tool for assisting in controlling position or action (or both). In this embodiment, one end of the jig is connected to the sensor of the testing machine, and the other end of the jig is connected to the plug-pull member of the sample to be tested, so as to drive the plug-pull member to move under the control of the testing machine to realize the plugging-pulling action.
Generally, the insertion and extraction force test items include an insertion force test and an extraction force test.
The sample jig used in the conventional insertion and extraction force testing method is too single, cannot meet the requirements of various testing conditions, and has the problem that the applied fixing force is not matched with the insertion and extraction force applied in the insertion force testing and extraction force testing.
Specifically, in the embodiment, when the jig is selected, the flat plate jig may be selected when the insertion and extraction force test item is the insertion force test, and the embedded jig may be selected when the insertion and extraction force test item is the extraction force test.
Taking a sample to be tested as a server mainboard and a memory bank as an example, the plugging seat plate is the server mainboard, the plugging piece is the memory bank, when the insertion force test is carried out, a flat plate type jig is used, the memory bank is pressed into the memory slot, and the flat plate type jig has the advantage that the buckle of the memory slot is not required to be detached in advance, so that the damage to the memory slot is avoided; when the pull-out force test is carried out, an embedded jig is used, and the embedded jig has the advantages that the memory bank can be fixed more stably, and the safety reliability and the data accuracy of the pull-out force test are improved.
Alternatively, the server board may be a PCBA (Printed Circuit board).
It should be understood that, for the purpose of performing data statistics of the subsequent insertion and extraction force test, the present embodiment may also perform data recording on the sample to be tested before or after step S11.
Specifically, the step of performing data recording on the sample to be tested may include: and recording related data of the sample to be detected, wherein the related data comprises an identity mark, a sample picture and a slot position mark.
Optionally, the identifier may be a P/N (Serial Number), a S/N (Part Number), a Location, and the like of the sample to be tested, and the slot position mark may be a mark and a remark of different memory slot positions on the sample.
Step S12: and fixing the sample to be tested on an object stage of the testing machine.
Specifically, a sample to be tested is fixed on an objective table of a testing machine, and two sides of the sample to be tested are fixed by a pressure rod.
Utilize the depression bar to fix the sample that awaits measuring, mean that there are more strong points, this makes the sample that awaits measuring can not take place offset at the plug in-process, and then ensures the correctness of plug spare inserted position for measured data is more accurate reliable.
It should be noted that the sample is completely fixed by the compression bar and no loosening or tilting occurs. If the fixing is not complete, the insertion and the extraction of the plugging piece can cause the movement of the plugging seat plate, which can cause the deviation of the measured data.
Meanwhile, a testing machine used in the conventional insertion and extraction force testing method can generally bear a load up to 30000N, which is 200 times of the actual requirement of the testing machine, the actual required strength of the testing machine is far exceeded, the configuration of high load cannot be fully utilized, the measurement accuracy of the instrument is low, and measurement errors may exist in the insertion and extraction force testing for memory slots and the like.
Therefore, the testing machine in the embodiment can be a push-pull force testing machine, the push-pull force testing instrument has higher testing precision, the testing method can accurately test the plugging and unplugging force of the memory slot of the server mainboard, and the subsequent testing stroke and the testing stress threshold value are set based on the push-pull force testing instrument, so that the safety and reliability of the whole plugging and unplugging force test can be improved.
The push-pull force testing machine mainly can be used for testing the tensile force, tearing, peeling, bonding force and the like of various materials, and can be generally divided into an economical door type tensile force machine, a desktop type tensile force testing machine, a micro-control type tensile force testing machine and the like.
Step S13: and mounting the corresponding jig on a sensor of the testing machine.
Alternatively, the sensor in the present embodiment may be a stress sensor capable of detecting a push-pull force.
Specifically, the corresponding jig is fixedly connected with the sensor, and the plugging seat plate of the sample to be tested is aligned with the sensor and keeps a preset distance.
Optionally, the sensor and the jig in this embodiment are fixedly connected and then disposed on a moving mechanism of the testing machine, so that the sensor and the jig are driven to move by the movement of the moving mechanism.
It should be understood that the preset distance can be flexibly set according to the type and size of the sample to be tested, so that the clamping moving space of the jig for the plug-in piece is ensured, and the collision safety is ensured.
For example, the predetermined distance may be 0.5 cm, 1cm, 2 cm, or the like.
Optionally, in this embodiment, the step of aligning the socket board with the sensor may be implemented automatically by using a testing machine, for example, performing image processing based on the sample picture and the slot position mark and the real-time image, determining the slot position in the real-time image, calculating the distance that the sensor needs to move when the socket board is aligned with the sensor, and then translating the sensor based on the calculated distance to align the socket board with the sensor.
In addition, the vertical movement of the sensor enables the plugging seat plate and the sensor to keep a preset distance, and the automatic realization of the testing machine can also be adopted, for example, the sample picture and the real-time image are depth images, and the vertical distance can be calculated according to the sample picture and the real-time image, so that the height control of the sensor is realized.
It should be noted that, when the position of the sensor is calibrated, the memory is aligned with the slot completely to ensure that the plug can be inserted into the slot completely.
Step S14: and setting the to-be-tested state of the to-be-tested sample according to the insertion and extraction force test item.
The state to be tested of the sample to be tested generally includes a state in which the plug corresponding to the insertion force test is not inserted and a state in which the plug corresponding to the extraction force test is inserted.
Continuing to take the server motherboard and the memory bank as an example, the unplugged state of the plug-in component is that the memory bank is lightly placed on the memory slot but not plugged, and the plugged-in state of the plug-in component is that the memory bank is completely plugged into the memory slot.
Optionally, the memory bank should vertically rest on the memory slot according to the insertion direction in the unplugged state of the plug-in element.
Step S15: and starting the testing machine to move the corresponding jig to perform insertion/extraction actions based on the operation parameters, and recording insertion/extraction force data.
The operation parameters comprise a maximum load value, a maximum stroke and a plugging and unplugging speed, and the test stroke and the test stress threshold are set based on the push-pull force tester, so that the stress threshold which can be borne by the sample to be tested is considered, the damage of the sample to be tested or the tester caused by the fact that the plugging force or the unplugging force applied by the tester in the plugging and unplugging force test exceeds the stress threshold which can be borne by the sample to be tested, the plugging and unplugging speed is too fast or the plugging depth exceeds the slot depth of the sample to be tested is avoided, and the safety and reliability in the plugging and unplugging force test process are improved.
Alternatively, the operation parameters in the present embodiment may further include a stroke origin position, a stroke origin detection, the number of measurements, a measurement stop position, a maximum air pressure number, and the like.
For the overall flow of the insertion and extraction force testing method, reference may be made to fig. 2, where fig. 2 is a schematic node diagram of an insertion and extraction force testing method provided in an embodiment of the present application.
The following explains the insertion and extraction force testing method through an example of a server motherboard and a memory bank:
