Description

Technical Field

[0001] The present invention relates to the technical field of tensile testing, and particularly to a tensile testing method and a tensile testing device. Background Art

[0002] During the wire harness processing, it is necessary to insert the terminal into the housing. During the insertion process, it is required that the operator first insert the terminal into the housing, then listen for a clicking sound, and then pull back the terminal. The pulling force needs to be controlled within 10N - 15N. However, this pulling force is difficult to standardize, and it is easy to apply too little or too much force, thus affecting the product quality. Therefore, it is urgent to design a testing method that can test the pulling force of the tester. Summary of the Invention

[0003] An object of the present invention is to provide a tensile testing method to solve the technical problem in the prior art that the pulling force of the tester cannot be tested, resulting in difficulty in standardizing the pulling force.

[0004] Another object of the present invention is to provide a tensile testing device applied to the above tensile testing method.

[0005] In particular, the present invention provides a tensile testing method, including the following steps:

[0006] Obtain the preset number of tensile values of the tester and the target judgment condition, where the tensile value is generated when the tester pulls the cable sample;

[0007] Judge whether each tensile value meets the target judgment condition;

[0008] If so, determine that the tensile test of the tester is qualified; otherwise, determine that the tensile test of the tester is unqualified.

[0009] Optionally, before the step of obtaining the preset number of tensile values of the tester and the target judgment condition, the following steps are further included:

[0010] Obtain the number of the tester;

[0011] Obtain the historical test data of the tester according to the number;

[0014] Optionally, the step of determining the level of the tester according to the historical test data specifically includes:

[0015] Determine the number of qualified times of the tester according to the historical test data;

[0016] Determine the level of the tester according to the number of qualified times.

[0017] Optionally, in the step of determining the level of the tester according to the number of qualified times, if the number of qualified times is less than the preset value, the level of the tester is the first level; if the number of qualified times is greater than or equal to the preset value, the level of the tester is the second level, and the second level is higher than the first level.

[0018] Optionally, in the step of determining the target judgment condition according to the level of the tester, if the level of the tester is the first level, determine that the target judgment condition corresponding to the tester is the first judgment condition; if the level of the tester is the second level, determine that the target judgment condition corresponding to the tester is the second judgment condition. The first judgment condition is whether the tensile force value is within the first preset range, and the second judgment condition is whether the tensile force value is within the second preset range, and the second preset range is within the first preset range.

[0019] Optionally, the first preset range is 10N to 15N, and the second preset range is 12N to 14N.

[0020] Optionally, before the step of judging whether each tensile force value meets the target judgment condition, it further includes:

[0021] Obtain the bending angle of the cable sample in real time when the tester pulls the cable sample each time;

[0022] Judge whether the bending angle of the cable sample each time is within the preset angle range;

[0023] If so, judge whether each tensile force value of the tester meets the target judgment condition; otherwise, determine that the tensile force test of the tester is unqualified.

[0027] In particular, the present invention also provides a tensile force testing device, including:

[0028] A control module, the control module includes a memory and a processor, and a calculation program is stored in the memory. When the calculation program is executed by the processor, it is used to implement the above-mentioned tensile test method.

[0029] In the present invention, the preset number of tensile force values and the target judgment conditions of the tester are first obtained, and then it is judged whether each tensile force value meets the target judgment conditions. If so, it is determined that the tensile test of the tester is qualified, otherwise it is determined that the tensile test of the tester is unqualified. The above technical solution can test the tensile force of the tester, and judge whether the tensile test of the tester is qualified by setting the target judgment conditions. The tester can be continuously trained in tensile force to generate muscle memory, gradually making the tensile force of each tester reach the standard, realizing the standardization of the tensile force of the tester, thereby improving the quality of the product.

[0030] Further, before the step of obtaining the preset number of tensile force values and the target judgment conditions of the tester in the present invention, the number of the tester is first obtained, and then the historical test data of the tester is obtained according to the number; then the level of the tester is determined according to the historical test data, and finally the target judgment conditions are determined according to the level of the tester. It can be understood that the target judgment conditions of the present invention are determined according to the level of the tester, and target judgment conditions with different degrees of strictness can be set according to the level of the tester. The higher the level, the stricter the target judgment conditions, so as to improve the accuracy of the tensile force of the tester.

[0031] Based on the following detailed description of the specific embodiments of the present invention in conjunction with the drawings, those skilled in the art will more clearly understand the above and other objects, advantages and features of the present invention. Description of the Drawings

[0032] Hereinafter, some specific embodiments of the present invention will be described in detail with reference to the drawings in an exemplary but non-limiting manner. The same reference numerals in the drawings denote the same or similar components or parts. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0033] Figure 1 is a schematic flowchart of a tensile test method according to an embodiment of the present invention;

[0034] Figure 2 is a schematic flowchart of a tensile test method according to another embodiment of the present invention;

[0035] Figure 3 is a schematic connection block diagram of a tensile test device according to an embodiment of the present invention. Detailed Embodiments

[0036] Figure 1 is a schematic flowchart of a tensile test method according to an embodiment of the present invention. AsFigure 1 As shown, in a specific embodiment, the tensile test method includes the following steps:

[0037] Step S100, obtain the tensile values of a preset number of times and the target judgment condition of the tester, where the tensile values are generated when the tester pulls the cable sample; here, the preset number of times can be 10 times, 12 times, etc.

[0038] Step S200, determine whether each tensile value meets the target judgment condition; if so, execute step S400; if not, execute step S300;

[0039] Step S300, determine that the tensile test of the tester fails;

[0040] Step S400, determine that the tensile test of the tester is qualified.

[0041] This embodiment can test the tensile strength of the tester. By setting the target judgment condition to determine whether the tensile test of the tester is qualified, the tester can be continuously trained in tensile strength to generate muscle memory, gradually making the tensile strength of each tester meet the standard, realizing the standardization of the tester's tensile strength, and thus improving the product quality.

[0042] Figure 2 It is a schematic flowchart of a tensile test method according to another embodiment of the present invention. As Figure 2 shown, before step S100 in this embodiment, the following steps are further included:

[0043] Step S10, obtain the tester's number;

[0044] Step S20, obtain the historical test data of the tester according to the number;

[0045] Step S30, determine the level of the tester according to the historical test data;

[0046] Step S40, determine the target judgment condition according to the level of the tester.

[0047] The target judgment condition of this embodiment is determined according to the level of the tester. Different target judgment conditions with different strictness levels can be set according to the level of the tester. The higher the level, the stricter the target judgment condition, so as to improve the accuracy of the tester's tensile strength.

[0048] In some embodiments, step S30 specifically includes:

[0049] Step 1: Determine the qualified number of times of the tester according to the historical test data;

[0050] Step 2: Determine the level of the tester according to the qualified number of times.

[0051] In this embodiment, the level of the tester is determined by the number of previous passes of the tester. The more passes, the higher the level of the tester; the fewer passes, the lower the level of the tester.

[0052] In step two, if the number of passes is less than the preset value, the level of the tester is the first level; if the number of passes is greater than or equal to the preset value, the level of the tester is the second level, and the second level is higher than the first level.

[0053] In step S40, if the level of the tester is the first level, it is determined that the target judgment condition corresponding to the tester is the first judgment condition; if the level of the tester is the second level, it is determined that the target judgment condition corresponding to the tester is the second judgment condition. The first judgment condition is whether the tensile force value is within the first preset range, and the second judgment condition is whether the tensile force value is within the second preset range. The second preset range is within the first preset range. Here, the second preset range being within the first preset range means that the lower limit value of the second preset range is greater than the lower limit value of the first preset range, and the upper limit value of the second preset range is less than the upper limit value of the first preset range. That is to say, the higher the level, the smaller the corresponding range value, so that the tester can be intensively trained.

[0054] In some embodiments, the first preset range is 10N - 15N, and the second preset range is 12N - 14N.

[0055] In some embodiments, the preset value can be 3 times, 4 times, 5 times, etc. In other embodiments, the preset value can also be determined according to specific design requirements. When the preset value is set to 5 times, if the number of passes of the tester is 5 times, the level of the tester can be set to the second level, and the second judgment condition corresponding to the tester is whether the tensile force value is within 12N - 14N. If the number of passes of the tester is 3 times, the level of the tester can be set to the first level, and the first judgment condition corresponding to the tester is whether the tensile force value is within 10N - 15N. It can be understood that after the number of passes reaches a certain value, more stringent test training is required for the tester. This is because, although the tensile force value of the tester is qualified, it may be 10N or 15N each time. In this case, the tensile force level of the tester has not reached a certain standard, and as long as the force is slightly larger or slightly smaller, it will affect the product quality. Therefore, on this basis, the tensile force of the tester is further trained, and more stringent judgment conditions are used to determine whether the tensile force value of the tester is qualified, and the final tensile force value of the tester is controlled within the range of 12N - 14N. Even if the force of the tester is slightly larger or smaller during the actual operation process, it will not affect the product quality.

[0056] In some embodiments, before step S200, it further includes:

[0057] Step S50: Obtain the bending angle of the cable sample in real time each time the tester pulls the cable sample.

[0058] Step S110: Determine whether the bending angle of the cable sample each time is within the preset angle range; if so, execute Step S200; otherwise, execute Step S300.

[0059] This embodiment not only considers testing the pulling force of the tester, but also considers that if the tester's gesture is incorrect when applying the pulling force, it may bend the cable sample, which will also affect the product quality. This embodiment judges the correctness of the tester's gesture indirectly by judging the bending angle of the cable sample. If the bending angle of the cable sample is within the preset angle range, it means that the tester's gesture is correct when pulling the cable sample. If the bending angle of the cable sample is not within the preset angle range, it means that the tester's gesture is incorrect when pulling the cable sample. In the case where the gesture is incorrect, it is necessary to determine that the tester's pulling force test is unqualified, and the tester's pulling force gesture needs to be strengthened to avoid cable bending and affecting product quality. Only when the bending angle of the cable sample is within the preset angle range each time and the pulling force value meets the target judgment condition each time can it be determined that the tester's pulling force test is qualified.

[0060] In Step S50, the bending angle of the cable sample can be obtained through a sensor.

[0061] In Step S110, the preset angle range is from -15° to 15°. In other embodiments, the preset angle range can also be determined according to specific design requirements, for example, it can be determined according to different types of cables.

[0062] In some embodiments, the pulling force test method further includes the following steps:

[0063] Control the red light to turn on when the pulling force value does not meet the target judgment condition, and control the green light to turn on when the pulling force value meets the target judgment condition.

[0064] This embodiment enables the tester to more intuitively know whether the pulling force value reaches the target judgment condition during each pulling force test through the control of the red light and the green light.

[0065] In some embodiments, a voice prompt can be combined to give the tester a reminder of passing or failing the test.

[0066] In some embodiments, after the tester completes the test, a reminder can also be given through the screen display. If the tester passes the test, "Test Passed" can be displayed on the screen. If the tester fails the test, "Test Failed" can be displayed on the screen.

[0067] In addition, this embodiment will generate a test report after each test is completed. The test report will show whether the tester's tensile test is qualified. If it is unqualified, the test report will show that the test failure was caused by the bending angle of the cable sample not being within the preset angle range or the test failure was caused by the unqualified tensile force value. In other words, the reason for the test failure will be stated in detail.

Figure 3 As shown, in some embodiments, the embodiment further provides a tensile testing device, the tensile testing device includes a control module 100, the control module 100 includes a memory 10 and a processor 20, the memory 10 stores a computing program, and the computing program is used to implement the tensile testing method of any of the above embodiments when executed by the processor 20.

The memory 10 is used to store the program executed by the processor 20.

The above computing program can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or an external storage device via a network (such as the Internet, a local area network, a wide area network and / or a wireless network).
