In the embodiment of the present invention, the pressing member 34 is disposed in a vertical direction. Therefore, it can be considered that the first end of the pressing member 34 is the upper end of the pressing member 34, and the second end of the pressing member 34 is the lower end of the pressing member 34.

The press test device has two states of a stationary (unpressed state) and a press test, which will be described below.

At rest, the elastic member 33 is in an initial compressed state, and the pressing member 34 naturally hangs down to provide support from the bottom of the casing 31.

When the test is pressed, the robot arm 2 drives the test head 3 to move toward the device to be tested, and presses the device to be tested through the pressing member 34 to perform a press test. In this embodiment, the device to be tested is placed on the base, and the mechanical arm 2 drives the test head 3 to move toward the device under test in the vertical direction (Z-axis direction), that is, the pressing member 34 moves toward the device to be tested, and performs a press test.

The device performs a press test to avoid the error caused by the pressure instability of the human hand, so that the test result is more accurate.

A second embodiment of the present invention relates to a press test device. The present embodiment is an improvement of the first embodiment. The main improvement is that, referring to FIG. 3, both ends of the elastic member 33 and the pressure sensor 32 and the pressing member The upper ends of 34 are fixedly connected.

In practice, since the two ends of the elastic member 33 are fixedly connected to the upper ends of the pressure sensor 32 and the pressing member 34 respectively, during the test, the pressure sensor 32 receives the tension or pressure from the elastic member 33, and the elastic member 33 is subjected to the elastic member 33. The pressure of the pressing member 34 or the pulling force of the pressing member 34. Therefore, in the present embodiment, the pressure sensor 32 may be a tension pressure sensor, and the elastic member 33 may be a tension spring.

It should be noted that the pressure of the tap level may be 0-20 g, but this embodiment does not Any restrictions can be set according to the test requirements.

In the first embodiment of the present invention, referring to FIG. 2, the pressure sensor 32, the elastic member 33, and the pressing member 34 are independently present.

At rest, the pressing member 34 supports the bottom of the housing 31 by the force of gravity, the pressure sensor 32 by the tensile force F and the gravity direction G of the _transmission case 31 at the top, the pressure sensor 32 at this time readout is negligible gravity :( spring) pressure sensor 32 Reading = F = G _pass .

When the pressing member 34 touches the device under test, the pressure sensor 32 by the upward force of the elastic member 33 and its own gravity G N _{transmission,} and the reading of the pressure sensor 32: pressure sensor 32 readings _pass = NG. At this time, the pressure applied to the device under test is _pressed N N elastic members 33 plus the force of gravity G _by the pressing member 34, i.e.: N = N + G _{press pressure} = sensor pressure readings + G 32 + G _{press pass.}

From the above, when the pressure sensor 32 is under tension and the critical point, i.e., reading of the pressure sensor 32 is 0, the device under test from the size of the force (G + G _{by mass)} starts, that is, in the first embodiment The test pressure range starts from (G _pass + G _press ).

In the present embodiment, referring to FIG. 3, both ends of the elastic member 33 are fixedly connected to the upper ends of the pressure sensor 32 and the pressing member 34, respectively.

At rest, the pressure sensor 32 by the pull-down N initial tension of _First elastic member 33 (which is equal to the pressing member 34, gravity) and _pass gravity G, the pressure sensor 32 at this time readout is negligible gravity :( spring) pressure Sensor 32 reading = N _initial + G _pass .

When the pressing member 34 touches the device under test, the pressure sensor 32 by the upward force of the elastic member 33 and its own gravity G N _{transmission,} and the reading of the pressure sensor 32: pressure sensor 32 reading = N + G _pass. At this time, the pressure applied to the device under test _pressure of the elastic member 33 N force of N, that is: N = N = _pressure pressure sensor 32 readings -G _pass.

It can be seen from the above that the sensor reading is greater than or equal to N _initial + G _transmission , so the N _{pressure is} greater than or equal to N _initial , and the N _initial direction is downward, which is represented by the pressure sensor 32 reading a negative number, which is provided by the elastic member 33 elastic force. _{At the beginning of the} preservation of N, the initial value is subtracted from the pressure calculation, so that the pressure range can be started from 0, that is, the tap test of the tap level can be completed.

Compared with the first embodiment, the present embodiment enables the press test device to perform the tap test at the tap level by improving the structure of the test head.

The body 31 and the limiting member 36; wherein the limiting member 36 is used for limiting the pressing member 34 such that the upper end of the pressing member 34 is located in the housing 31.

In practice, the limiting member 36 can include two portions, a portion of which is fixed in the housing 31, and can limit the upper end of the pressing member 34 so that the upper end of the pressing member 34 is located in the housing 31, and the pressing member 34 is ensured. The other portion is fixed to the outside of the casing 31, and the other end of the pressing member 34 (i.e., the pen tip) can be restrained so that the other end of the pressing member 34 is located outside the casing 31. At the same time, the limiting member 36 is detachable, and when the limiting member 36 is removed, the pressing member 34 can be taken out from the housing 31 for replacement.

Installation, this embodiment is not limited thereto, and can be set according to actual test requirements.

Compared with the first embodiment, the present embodiment provides two replaceable pen head structures, which facilitates the replacement of the pen tip during testing, and at the same time saves a certain cost.

A fourth embodiment of the present invention provides a press test system comprising: a main control device and the press test device according to any one of the first to third embodiments.

The main control device is connected to the mechanical arm 2, the pressure sensor 32 and the device to be tested; wherein the main control device is used for controlling the movement of the mechanical arm 2 toward the device to be tested, so that the mechanical arm 2 drives the test head 3 to move toward the device to be tested, and passes The pressing member 34 presses the device to be tested to perform a press test.

Compared with the prior art, the embodiment controls the pressing test device by the main control device to complete the pressing test process, which can realize automatic testing and improve testing efficiency.

A fifth embodiment of the present invention provides a press test method applied to the above-described press test system. A flow chart of the press test method is shown in FIG. 6.

Step 101: The control robot arm moves a preset distance toward the device to be tested to press the device under test by the pressing member.

Specifically, the control arm moves a preset distance toward the device to be tested, and the test head also moves correspondingly to the device to be tested for a predetermined distance. At this time, the elastic member of the test head is pressed, and the elastic member applies pressure to the pressing member. In order to press the pressing member against the device to be tested.

In the present embodiment, the preset distance is to obtain the Hook coefficient of the elastic member, which can be set empirically. Specifically, the stretching and compression distance of the spring has a certain range, and excessive stretching may cause irreversible deformation. Therefore, the preset distance is set within a range in which the spring is normally stretched or compressed.

Step 102: Receive a first pressure sensing value generated by the device to be tested, and calculate a Hook coefficient of the elastic component according to the first pressure sensing value and the preset distance.

Specifically, when the pressing member presses the device to be tested, the pressure sensing value at this time can be read by the pressure sensor. In the case where the pressure sensing value and the preset distance are known, according to Hooke's law formula F=-K*X, where F is the pressure at which the elastic member is deformed, and X is the length at which the elastic member is elongated or shortened, K is Hook coefficient. According to this, the Hook coefficient of the elastic member can be calculated.

Step 103: Calculate a test distance corresponding to the target test pressure according to the Hook coefficient and the preset target test pressure.

Specifically, during the test, at least one target test pressure (generally a plurality) is pre-set, and the test distance corresponding to the target test pressure can be calculated from the Hook coefficient of the elastic member and the target test pressure. That is, the calculation is performed using the Hooke's law formula F=-K*X.

Among them, the target test pressure can be preset in two ways:

In the first pressure preset mode, the pressing test device provides a pressure setting interface to directly receive the set target test pressure, that is, the target test pressure is directly set by the tester.

The second pressure preset method first provides a pressure setting interface, receiving a pressure test range and a pressure test step. Specifically, a pressure setting interface can be provided on the display screen, and the tester can perform an operation, inputting a pressure test range and a pressure test step. The pressure test step is a constant increment. Starting from 0, the test pressure value is continuously increased by the pressure test step, so that the feedback effect of the device under test can be tested under various test pressures.

It should be noted that the pressure test range may be (0, 2000 g), and the test step needs to be set according to the pressure level to be tested, and the embodiment does not impose any limitation on this.

Then, the target test pressure is calculated based on the pressure test range and the pressure test step. Specifically, within the pressure test range, starting from 0, the pressure value is stepped up by the pressure test step and used as the target test pressure. According to the user-defined test pressure, the pressure of the device to be tested can be performed at various levels. test. For example, the preset pressure test step is 10g and the touch test pressure range is (0, 20g). At this time, when the target test pressure is 10g, 20g, it is within the range of the light touch test pressure, and the light touch level pressure test is performed.

Step 104: Perform a press test according to the test distance of the device to be tested.

Specifically, the control arm moves toward the test device to test the distance, the pressing member presses the device to be tested, and the device to be tested is subjected to a press test to check the effect of the device under test under the target test pressure (ie, determining whether the device to be tested is executed or not) The operational function corresponding to the target test pressure).

It should be noted that, because the Hook coefficients of different elastic members are different, even if the same elastic member, the use time affects the Hook coefficient, and the pressing test of the present embodiment is automated, therefore, each time When the test is pressed, the Hook coefficient of the elastic member needs to be recalculated, so that the test distance corresponding to the target test pressure can be determined to realize the automatic test.

In practice, it is also possible to recalculate the Hook coefficient of the elastic member after each predetermined number of tests, which can improve the test efficiency to a certain extent. However, the embodiment does not impose any limitation on this, and can be set according to the test requirement; in the actual test, if the test accuracy is high, the Hook coefficient of the elastic member can be recalculated each time the test is pressed; To ensure a certain accuracy, but need to increase the test speed, you can recalculate the Hook coefficient of the elastic member after each preset number of tests.

Compared with the prior art, the embodiment of the present invention uses a mechanical arm to drive the test head to perform a press test on the device to be tested, thereby avoiding the error caused by the pressure instability of the human hand, and making the test result more accurate.

The steps of the above various methods are divided for the sake of clear description. The implementation may be combined into one step or split into certain steps and decomposed into multiple steps. As long as the same logical relationship is included, it is within the protection scope of this patent. The addition of insignificant modifications to an algorithm or process, or the introduction of an insignificant design, without changing the core design of its algorithms and processes, is covered by this patent.

A sixth embodiment of the present invention provides a press test method, which is an improvement of the fifth embodiment, and the main improvement is that the test distance is calibrated.

Please refer to FIG. 7 for a specific flowchart of the pressing test method of the present embodiment.

The step 201 to the step 203 are substantially the same as the step 101 to the step 103. The step 208 and the step 104 are substantially the same, and are not described here. The difference is that the step 204 to step 207 are newly added in this embodiment. Explain as follows:

Step 204: Control the mechanical arm to move the test distance toward the device under test to press the device under test by the pressing member.

Specifically, here is substantially the same as step 101, and the preset distance is used as the test distance.

Step 205: Receive a second pressure sensing value generated by the device to be tested, and determine whether the second pressure sensing value matches the target testing pressure. If yes, go to step 208; if no, go to step 206.

Specifically, the pressure sensor is read here to control the second pressure sensing value under the robot arm motion test distance. If the second pressure sensing value does not match the target test pressure, the process proceeds to step 206 to calibrate the pressure value; If the second pressure sensing value matches the target test pressure, it means that calibration is not required, and the device to be tested can be directly tested according to the test distance.

It should be noted that, if it is determined whether the second pressure sensing value matches the target test pressure, whether the absolute value of the difference is less than a preset value may be used as a determination condition, and the preset value is, for example, 5 g. That is, when the absolute value of the difference between the second pressure sensing value and the target test pressure is less than 5 g, it is determined that the second pressure sensing value is matched with the target test pressure; and the absolute value of the difference between the second pressure sensing value and the target test pressure If it is greater than 5g, it is determined that the second pressure sensing value does not match the target test pressure. This embodiment does not impose any limitation on this, and can be set according to test requirements.

Step 206: Adjust the distance that the robot arm moves toward the device under test so that the second pressure sensing value matches the target test pressure.

Specifically, when the second induced pressure value does not match the target test pressure, the appropriate adjustment machine The distance the arm moves toward the device under test such that the second pressure sensing value matches the target test pressure.

In this embodiment, the specific manner of adjusting the distance that the arm moves toward the device under test is: when the second induced pressure value is greater than the target test pressure, the distance of the adjusting arm toward the device to be tested is appropriately reduced; When the pressure value is less than the target test pressure, the distance of the adjustment arm to the device under test is appropriately reduced. Accordingly, the second pressure sensing value can be matched to the target test pressure.

In step 207, the test distance is updated to the distance that the adjusted robot arm moves toward the device under test.

Specifically, the distance that the adjusted mechanical arm moves toward the device under test is a more accurate distance value, and therefore, the test distance is updated to the distance that the adjusted mechanical arm moves toward the device under test, so that the next The test results are more accurate.

Compared with the fifth embodiment, the present embodiment calibrates the test distance, further ensuring the accuracy of the test result is improved.
