Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Fig. 1 is a schematic structural diagram of a drop test apparatus according to an embodiment of the present invention.
In the manufacturing process of the terminal, the reliability test is an important ring in the product test, wherein one important assessment standard in the reliability standard is a drop test. The drop test equipment in the related art is provided with a sensor at a fixed position, detects a sample terminal and then releases the sample terminal, and the air suction and air break of the drop test equipment have time delay, so that the speed from the released position to the drop to the ground of the sample terminal is not necessarily the required speed, the randomness of the drop test result can be caused, and the drop test effect is poor.
In order to solve the technical problem, an embodiment of the present invention provides a drop test device, including a sensor module connected to a release module, where the sensor module is configured to detect a free fall motion of the release module, and a control module respectively connected to an adsorption module and a sensor, where the control module is configured to trigger to perform air cut-off control on the adsorption module when the sensor module detects the free fall motion and the free fall motion satisfies a preset condition, and when the sensor module detects that the free fall motion of the release module satisfies the preset condition, the control module triggers to perform air cut-off control on the adsorption module to perform drop detection on a sample terminal.
Referring to fig. 1, the drop test apparatus 10 includes: drag module 101, release module 102, and adsorb module 103, its characterized in that still includes:
a sensor module 104 coupled to the release module 102, the sensor module 104 being configured to detect free-fall movement of the release module 102.
And the control module 105 is connected with the adsorption module 103 and the sensor respectively, and the control module 105 is used for triggering the air-cut-off control of the adsorption module 103 when the sensor module 104 detects the free falling body movement and the free falling body movement meets the preset conditions.
The preset conditions are preset, and may be dynamically set according to actual drop test requirements, or may be preset by a factory program of the drop test device 10, which is not limited to this.
In the embodiment of the invention, the practical application of the drop test device 10 is considered, the sensor module 104 is installed at a certain height position at the upper end of the shock absorption mechanism of the drop test device 10, and the sensor module 104 is connected with the release module 102, so that the release of the sample terminal can be sensed. Because the sample terminal is when releasing, absorption module 103 has the time delay, and the sample terminal probably collides damping device, can reserve sufficient position for preventing this condition appears, can release sample terminal in advance, prevents that sample terminal from hitting damping device and influencing sample terminal test result.
Therefore, in the embodiment of the present invention, a certain position may be reserved for the free fall movement of the release module 102, for example, a 1-meter type drop test may reserve a height value of h1, so that, when a 1.5-meter type drop test is performed, the reserved height value h2 may be set, where h2 > h1, and in the embodiment of the present invention, for convenience of management, the reserved height value is set to h 2.
In the embodiment of the invention, it is also considered that, as the sample terminal is attached to the release module 102 through the suction cup, the release angle of the sample terminal in advance has a certain deflection, so that the sample terminal is inconsistent with the required speed when falling to the ground, the randomness of the sample terminal is increased during testing, and the experimental result is influenced. Therefore, the sample terminal in the embodiment of the present invention is preferably set to be smaller in h without colliding with the damping device.
In the embodiment of the present invention, in order to reserve a certain position for the free fall motion of the releasing module 102 based on the above, in an actual drop test process, the free fall motion of the releasing module 102 may be detected based on the sensor module 104 connected to the releasing module 102, and when the sensor module 104 detects the free fall motion and the free fall motion satisfies a preset condition, the adsorption module 103 is triggered to perform the air-break control to release the sample terminal for drop detection, that is, when the free fall motion of the releasing module 102 compensates the reserved certain position, the adsorption module 103 is triggered to perform the air-break control to release the sample terminal for drop detection, so that the detection randomness is technically effectively reduced.
In the embodiment of the invention, different reserved height values can be set for different types of drop tests, for example, a 1-meter type drop test can be performed, and the reserved height value can be h1, so that when a 1.5-meter type drop test is performed, the reserved height value h2 can be set because the speed is higher, and h2 is greater than h 1.
Therefore, for the drop test device 10, for different reserved height values, the thresholds for determining whether the free fall motion meets the preset condition are different, referring to fig. 2, in the embodiment of the present invention, a storage module 107 may be further built in the operation panel 106 connected to the control module 105, the control module 105 is connected to the storage module 107, and the storage module 107 stores test data, where the test data includes: the type of test performed on the sample terminal (e.g., a 1 meter type drop test, or a 1.5 meter type drop test), and a threshold corresponding to each type (the threshold is used to make a determination whether the free fall motion satisfies a preset condition, and the corresponding thresholds are different for different types).

In a specific implementation process of the embodiment of the present invention, the target time threshold may be calculated based on a reserved height value corresponding to a type of a currently performed drop test, for example, if the type of the currently performed drop test is a 1-meter drop test, and a reserved height value corresponding to the 1-meter drop test is h1, a time value may be calculated in advance according to h1 and the acceleration of gravity and used as the target time threshold.
