[0047] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0048] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0049] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a click test device, which includes a stepper motor 1, a reciprocating member 2, an elastic probe member 3, a Hall sensor 4 and a test pin 5; the output shaft of the stepper motor 1 is provided with a belt transmission mechanism 11; the reciprocating member 2 is arranged in the belt transmission mechanism 11, and can reciprocate with the belt transmission mechanism 11; the elastic probe member 3 is transmission-connected to the reciprocating member 2, and both ends can respectively and synchronously extend in the same direction under the reciprocating drive of the reciprocating member 2; the Hall sensor 4 is spaced apart at one end of the elastic probe member 3, and can be triggered when one end of the elastic probe member 3 is extended; the test pin 5 is connected to the other end of the elastic probe member 3.
[0050] The click test device can be specifically but not limited to being applied to a press-click test of a laptop keyboard, a press-click test of a touch screen, etc. The use is explained by taking the press-click test of a laptop keyboard as an example.
[0051] When the click test device is used, first, the stepper motor 1 outputs positive and negative step angles of fixed size to make the belt transmission mechanism 11 generate a corresponding reciprocating linear motion of a fixed length, so that the reciprocating member 2 can move back and forth with the belt transmission mechanism 11, and the elastic probe member 3 is transmission-connected to the reciprocating member 2, and both ends can be respectively and synchronously extended in the same direction under the reciprocating drive of the reciprocating member 2. For example, when the reciprocating member 2 reciprocates up and down, the rising movement of the reciprocating member 2 drives the two ends of the elastic probe member 3 to extend upward in the same direction synchronously, and the descending movement of the reciprocating member 2 drives the two ends of the elastic probe member 3 to extend downward in the same direction synchronously, and the Hall sensor 4 and the test ejector pin 5 are respectively arranged at the two ends of the elastic probe member 3. In this way, in a reciprocating motion cycle of the reciprocating member 2 (such as the above-mentioned rising and falling motion cycles), the Hall sensor 4 can be triggered once and the test ejector pin 5 can be extended and pushed once, thereby realizing a press and click test on the laptop keyboard and recording the number of tests at the same time.
[0052] Compared with the click test equipment using pressure sensors in the prior art, the click test equipment provided by the embodiment of the present disclosure uses a Hall sensor 4 with low manufacturing cost, and through the reciprocating member 2 driving the elastic probe member 3 to move back and forth once, the Hall sensor 4 can be triggered once and the test ejector pin 5 can be probed and pushed once, and the click test and the recording of the test times are performed separately without interfering with each other.
[0053] In summary, the click test device provided by the embodiment of the present disclosure has the beneficial effects of simple structure, low manufacturing cost, and being able to execute the press-click and test-record functions respectively.
[0054] In one embodiment, the reciprocating member 2 includes a first shell member 21 and a second shell member 22 that are connected to each other; the first shell member 21 is fixedly connected to the belt body in the belt transmission mechanism 11; the second shell member 22 is provided with an installation hole for installing the elastic probe member 3; wherein the second shell member 22 can drive the elastic probe member 3 to reciprocate periodically with the first shell member 21 to trigger the Hall sensor 4.
[0055] Specific, combined Figure 1 To further explain in detail, the reciprocating member 2 is specifically configured as a first shell member 21 and a second shell member 22 that are connected to each other, and the first shell member 21 is fixedly connected to the belt body in the belt transmission mechanism 11; the second shell member 22 is provided with a mounting hole for installing the elastic probe member 3, so that when the belt body in the belt transmission mechanism 11 makes a reciprocating linear motion, the second shell member 22 can drive the elastic probe member 3 to reciprocate linearly with the first shell member 21, thereby periodically triggering the Hall sensor 4 and periodically probing and pushing the test ejector pin 5.
[0056] The specific arrangement of the reciprocating member 2 can not only realize the reciprocating synchronous motion with the belt body in the belt transmission mechanism 11 , but also realize the installation of the elastic extension member 3 .
[0057] In one embodiment, the elastic probe member 3 includes a linear bearing 31 and a probe rod 32; the linear bearing 31 is fixedly installed in the mounting hole of the second shell 22; the probe rod 32 is at least partially installed in the linear bearing 31; wherein, the two ends of the probe rod 32 can elastically extend in the same direction when the second shell 22 moves back and forth.

In this way, when the two ends of the probe rod 32 are reciprocated by the second shell 22 to trigger the elastic extension, the probe rod 32 can slide linearly in the inner hole of the linear bearing 31, which greatly reduces the friction resistance of the probe rod 32 when extending, and can also provide certain guidance and limitation on the extending direction of the probe rod 32.
[0059] In one embodiment, the probing rod 32 has a trigger rod section 321 that is snap-fitted to the mounting hole in the second shell 22; the trigger rod section 321 separates the probing rod 32 into two probing rod ends; the trigger rod section 321 can be triggered when the reciprocating member 2 moves, and drives the two probing rod ends to simultaneously extend toward the Hall sensor 4, or simultaneously extend away from the Hall sensor 4.
[0060] Specific, combined Figure 3 To further explain in detail, the trigger rod segment 321 in the probe rod 32 is correspondingly connected with the mounting hole in the second shell 22, so that when the second shell 22 moves in a straight line, the force can be directly transmitted to the trigger rod segment 321, and the elastic clamp in the trigger rod segment 321 can be triggered accordingly, thereby driving the two probe rod ends to simultaneously extend toward the Hall sensor 4, or simultaneously extend away from the Hall sensor 4.
[0061] At that time, the extension rod 32 may also adopt a structure with other telescopic functions, for example, a structure similar to the telescopic rod in a folding umbrella.
[0062] The specific configuration of the probe rod 32 has the beneficial effects of simple structure, stable and efficient probe triggering.
[0063] In one embodiment, a permanent magnet 33 is provided at one end of the probe rod 32 close to the Hall sensor 4, and the other end is connected to the test pin 5; the permanent magnet 33 can trigger the Hall sensor 4 when the probe rod 32 extends to the extreme position toward the Hall sensor 4.
[0064] Specific, combined Figure 1 To further explain in detail, a permanent magnet 33 is provided at one end of the probe rod 32 close to the Hall sensor 4, so that when one end of the probe rod 32 moves toward the Hall sensor 4, the magnetic field strength of the permanent magnet 33 can act to trigger the Hall sensor 4, thereby realizing the function of recording a probe click movement of the probe rod 32.
[0065] In one embodiment, the reciprocating member 2 also includes a clamping head 25, a guide rod 23 and a sliding sleeve 24; the clamping head 25 is arranged on the side of the first shell 21 facing away from the second shell 22, and is used to clamp and fix the belt body in the belt transmission mechanism 11; the guide rod 23 is arranged parallel to the belt body in the belt transmission mechanism 11; the sliding sleeve 24 is arranged on the first shell 21, and is movably sleeved on the guide rod 23.
[0066] Specific, combined Figure 1 To further explain in detail, a clamping head 25, a guide rod 23 and a sliding sleeve 24 are further arranged in the reciprocating member 2, and the clamping head 25 is arranged on the side of the first shell 21 facing away from the second shell 22, and can be clamped and pressed together with the first shell 21, so that the reciprocating member 2 can be stably fixed to the belt body in the belt transmission mechanism 11; the sliding sleeve 24 is movably sleeved on the guide rod 23, which can reduce the friction force of the reciprocating member 2 when it reciprocates along the guide rod 23 on the one hand, and can also guide and straighten the movement path of the reciprocating member 2 on the other hand.
[0067] In one embodiment, the click test device also includes a reversing switch 6 electrically connected to the stepper motor 1; the reversing switches 6 are arranged at intervals on both sides of the reciprocating member 2 along the reciprocating movement direction of the reciprocating member 2; when the first shell 21 reciprocates to the extreme position, the reversing switch 6 can be triggered to change the direction of the stepper motor 1.
[0068] Specific, combined Figure 3 To further explain in detail, two reversing switches 6 are respectively arranged at intervals on both sides of the reciprocating member 2 along the reciprocating movement direction of the reciprocating member 2, and when the first shell 21 moves linearly to the extreme position on one side, the reversing switch 6 on that side can be triggered respectively, so that the direction of the stepper motor 1 can be changed by the reversing switch 6, thereby realizing the forward and reverse switching of the stepping angle output by the stepper motor 1, and realizing the function of driving the reciprocating member 2 in reverse.
[0069] The specific configuration of the reversing switch 6 has the beneficial effects of simple structure, being able to stably switch the direction of the stepping motor 1 and timely change the moving direction of the reciprocating member 2 .
[0070] In one embodiment, an end of the test ejector pin 5 facing away from the elastic probe 3 is detachably provided with an ejector pin cap 51 .
[0071] Specific, combined Figure 3 To further explain in detail, the above-mentioned ejector cap 51 can be specifically but not limited to being set to be detachably installed on one end of the test ejector 5 in a threaded connection manner. In this way, when performing click tests on different products to be tested, ejector caps 51 of different textures can be switched. For example, when performing a click test on a screen, it can be switched to a soft silicone ejector cap 51, and when performing a click test on a keyboard, it can be switched to a hard plastic ejector cap 51.
[0072] The specific arrangement of the ejector cap 51 has the beneficial effects of simple structure and convenient insertion and switching.
[0073] In one embodiment, the click test device also includes a mounting frame 7; the mounting frame 7 has a vertical frame 71 for mounting the belt transmission mechanism 11, and a horizontal frame 72 vertically arranged on the bottom side of the vertical frame 71; one end of the test pin 5 is inserted through the horizontal frame 72 and extends downward to form a test end.
[0074] Specific, combined Figure 3 To further explain in detail, the mounting frame 7 is specifically configured as a vertical frame 71 for mounting the belt transmission mechanism 11 and a horizontal frame 72 vertically arranged on the bottom side of the vertical frame 71, and one end of the test pin 5 is inserted into the horizontal frame 72 and extends downward to form a test end. In this way, the vertical frame 71 can be directly fixed and the product to be tested can be placed parallel to the bottom of the horizontal frame 72. The belt transmission mechanism 11 can stably drive the test pin 5 to extend reciprocally downward in the driving state.
[0075] The specific arrangement of the mounting bracket 7 has the beneficial effects of being simple in structure, being able to stably fix the belt transmission mechanism 11 and movably fix the test ejector pin 5 .
[0076] In one possible implementation, the click test device further includes a laser distance measurement module 8 disposed on a side of the horizontal frame 72 facing away from the vertical frame 71 ; the laser distance measurement module 8 is electrically connected to the machine vision module in the click test device.
[0077] Specific, combined Figure 3 To further explain in detail, the above-mentioned laser ranging module 8 can be specifically but not limited to being set as a laser ranging light. The laser ranging module 8 can measure the real-time distance between the click test device and the product to be tested in real time, and feed it back to the machine vision module in the click test device, so as to adjust the actual distance between the click test device and the product to be tested in time, and avoid the beneficial effect of the test ejector 5 damaging the product to be tested due to the distance being too close.
