Description

Technical Field

[0001] The present invention relates to a vibration detection device and a vibration detection method, and in particular to a vibration detection device and a vibration detection method capable of performing rapid detection. Background Art

[0002] The traditional touch panel detection technology is to install sensors with acceleration sensing and pressure sensing functions on a robotic arm. The robotic arm must be moved to multiple test positions of the touch panel in turn to perform acceleration and pressure sensing of each test position, which consumes a lot of detection time. In addition, the sensor with pressure sensing function is directly installed on the front end of the robotic arm; if the robotic arm moves quickly from one test position of the touch panel to another test position, the vibration amplitude caused by the movement of the robotic arm may exceed the vibration amplitude of the touch panel, causing the sensor with acceleration sensing function to sense vibrations that do not belong to the touch panel when the robotic arm descends to approach the touch panel, affecting its judgment. Therefore, the traditional touch panel detection technology requires the robotic arm to move slowly, which further prolongs the required detection time. Therefore, how to design a detection device that can quickly detect the vibration and acceleration related parameters of the touch panel is one of the development goals of the related panel detection industry.

[0051] See also Figures 1 to 3 , Figure 1 is a schematic diagram of an application of the vibration detection device 10 according to an embodiment of the present invention, Figure 2 is a schematic diagram of the structure of the vibrating touch panel 14 in an embodiment of the present invention, Figure 3 Schematic diagram of the appearance of the vibrating touch pad 14 in an embodiment of the present invention. The vibration detection device 10 can be used to detect the vibrating touch pad 14 of the laptop computer 12. The vibrating touch pad 14 at least includes a touch surface 16, a position detection module 18 and a vibration module 20. The touch surface 16 is the outer covering of the vibrating touch pad 14; the user can use an external object, such as a finger, a stylus, or a detection arm of the vibration detection device 10 to click or move on the touch surface 16. The touch surface 16 is fixedly mounted on the shell of the vibrating touch pad 14, which means that when the vibrating touch pad 14 is operated, the touch surface 16 will not drop and therefore there is no pressing stroke. The position detection module 18 is located below the touch surface 16 and uses capacitive sensing or other sensing technologies to detect the contact coordinate points of the external object on the touch surface 16 and its movement trajectory.

[0052] The vibration module 20 may include a plurality of piezoelectric elements 22, which are distributed at different positions under the touch surface 16 to generate vibration feedback. The vibrating touch pad 14 may also include a trigger unit 23, which is also distributed at different positions under the touch surface 16 to detect the force value of the external object. When the force value applied by the external object to the vibrating touch pad 14 reaches a predetermined threshold, the trigger unit 23 drives the vibration module 20 and the touch surface 16 to vibrate through the piezoelectric element 22, and the vibration can provide various types of vibration feedback parameters, such as vibration amplitude, vibration delay time, and vibration duration, but the actual application is not limited thereto. The vibration amplitude is the maximum oscillation displacement of the touch surface 16 driven by the piezoelectric element 22, the vibration delay time is the time difference from the external object touching the touch surface 16 to the vibration module 20 generating vibrations reaching a predetermined amplitude, and the vibration duration is the time difference from the vibration module 20 generating vibrations reaching a predetermined amplitude to the end of the vibration.

[0053] The present invention sets a plurality of test points P on the vibrating touch panel 14, which are distributed at different positions on the touch surface 16; Figure 3 In the embodiment shown, the vibrating touch panel 14 provides nine test points P, the number and position of which are not limited to the aforementioned examples, but depend on design requirements. Generally speaking, the number of piezoelectric elements 22 is usually less than the number of test points P, but the actual application is not limited to this. The distribution position of the piezoelectric element 22 on the touch surface 16 can be aligned with a certain test point P, or aligned with the position between multiple test points P, and the setting variation can be determined according to the number and distribution of the test points P and the piezoelectric elements 22. The vibration detection device 10 can synchronously detect the vibration feedback parameters of the nine test points P of the vibrating touch panel 14 under various vibration modes to achieve the purpose of rapid detection.

[0054] In a preferred embodiment of the present invention, the vibration module 20 can provide a variety of vibration modes using any combination of multiple piezoelectric elements 22 to provide vibration feedback for the vibrating touch panel 14 in various possible scenarios; for example, four piezoelectric elements 22 can provide: a vibration mode that triggers one of the piezoelectric elements 22, a vibration mode that triggers two of the piezoelectric elements 22, a vibration mode that triggers three of the piezoelectric elements 22, and a vibration mode that triggers all of the piezoelectric elements 22. Regardless of the vibration mode that the vibrating touch panel 14 is triggered with, the vibration detection device 10 uses all acceleration sensors to test the vibration feedback parameters of all test points P of the vibrating touch panel 14.

[0055] See also Figure 4 , Figure 5 and Figure 6 , Figure 4 FIG. 1 is a partial side view of the vibration detection device 10 according to an embodiment of the present invention. Figure 5 is a partial structural diagram of an embodiment of the present invention, Figure 6FIG. 1 is a partial schematic diagram of the appearance of the vibration detection device 10 in another operation stage according to an embodiment of the present invention. The vibration detection device 10 may include a first detection module 24, a second detection module 25, and a drive motor 26. The drive motor 26 is used to drive the first detection module 24 and the second detection module 25 to move closer to or away from the vibrating touch panel 14. Figure 4 and Figure 5 As shown, the first detection module 24 may include a first movable platform 28, a circuit substrate 30, an acceleration sensor 32 and a positioning element 34. The first movable platform 28 may be relatively close to or away from the vibrating touch panel 14 as the driving motor 26 is activated. A plurality of acceleration sensors 32 are arranged in an array and coplanar manner on the surface of the circuit substrate 30 facing the vibrating touch panel 14 (or referred to as: a plurality of acceleration sensors 32 are arranged in an array and coplanar manner on the surface of the circuit substrate 30 away from the first movable platform 28), and the acceleration sensors 32 are covered by an outer cover 36, and the sensing data of all acceleration sensors 32 are outputted by the same signal line. The number of acceleration sensors 32 may be the same as the number of points P to be measured, and their positions also correspond to the positions of the points P to be measured. The circuit substrate 30 is arranged on the first movable platform 28. The positioning element 34 is arranged on the first movable platform 28.

[0056] Normally, the vibrating touch panel 14 is placed on the test platform 38. When the driving motor 26 moves the first detection module 24 to make the first movable platform 28 close to the vibrating touch panel 14, the positioning element 34 can be positioned against the vibrating touch panel 14 or the test platform 38 to limit the movement of the plurality of acceleration sensors 32 relative to the vibrating touch panel 14, ensuring that the acceleration sensors 32 can stably touch the test point P or its surrounding area, so as to simultaneously detect the vibration feedback parameters provided by all the test points P, thereby obtaining the vibration amplitude, vibration delay time and vibration duration of the vibrating touch panel 14 at each test point P. In a preferred embodiment of the present invention, the positioning element 34 can be a suction cup, a latch, or any other component with a positioning function. The vibration detection device 10 drives all acceleration sensors 32 of the first detection module 24 to touch all corresponding test points P of the vibrating touch panel 14 in a surface contact manner at the same time; no matter how many piezoelectric elements 22 are enabled by the vibration module 20 to apply vibration to the touch surface 16, the first detection module 24 can simultaneously detect the vibration feedback parameters of all test points P on the touch surface 16.

[0057] In the present invention, when the vibration detection device 10 drives the multiple acceleration sensors 32 of the first detection module 24 to align with and touch the multiple test points P of the vibrating touch panel 14, an additional control circuit (not shown in the attached figure) can be used to drive the vibration module 20 of the vibrating touch panel 14 to trigger multiple vibration modes in a predetermined order, so as to simultaneously measure the vibration feedback parameters provided by all the test points P in various vibration modes. Alternatively, the vibration detection device 10 can also drive the multiple acceleration sensors 32 of the first detection module 24 to touch the multiple test points P of the vibrating touch panel 14, and the external force of touching the test points P reaches the extent that the piezoelectric element 22 of the vibrating touch panel 14 can be triggered, so that the vibration feedback parameters provided by all the test points P in various vibration modes can be measured simultaneously without the need for an additional control circuit. The triggering method of the vibration module 20 is not limited to the aforementioned state, and it depends on the design requirements.

[0058] See also Figure 6 , Figure 6 FIG. 2 is a partial schematic diagram of the appearance of the vibration detection device 10 in another operation stage according to an embodiment of the present invention. The second detection module 25 of the vibration detection device 10 provides a pressure sensing function for detecting the force applied by an external object to the vibrating touch panel 14. The first detection module 24 and the second detection module 25 can be alternately installed on the detection arm of the vibration detection device 10 (e.g. Figure 1 The vibration detection device 10 may include a first detection module 24 and a second detection module 25. The first detection module 24 may be removed from the detection arm and the second detection module 25 may be installed on the detection arm; or, the vibration detection device 10 may have two detection arms, and the first detection module 24 and the second detection module 25 may be respectively arranged in different detection arms for alternate use. The second detection module 25 may include a second movable platform 40 and a pressure sensor 42. The second movable platform 40 may be moved closer to or away from the vibrating touch panel 14 by the actuation of the driving motor 26. The pressure sensor 42 may be arranged on the second movable platform 40 via a circuit substrate (not shown in the figure).

[0059] like Figure 6As shown, the vibrating touch panel 14 is placed on a test platform 38 that can move in two axes; however, the structural design of the test platform 38 is not limited to this style, and it depends on the actual needs. The driving motor 26 drives the second movable platform 40 to approach the vibrating touch panel 14, so that the pressure sensor 42 with a high response frequency can stop at multiple test points P of the vibrating touch panel 14 in turn with the rapid movement of the test platform 38, so as to obtain the force value provided by the pressure sensor 42 when generating vibration feedback parameters at each test point P. In other words, the driving motor 26 will gradually increase the external force applied by the pressure sensor 42 of the second detection module 25 to any test point P until the piezoelectric element 22 of the vibrating touch panel 14 is vibrated by the trigger unit 23, and the accumulated change of the external force applied by the pressure sensor 42 is read as the force value.

[0060] See also Figure 7 and Figure 8 , Figure 7 and Figure 8 FIG. 1 is a flow chart of a vibration detection method in different stages according to an embodiment of the present invention. Figure 7 and Figure 8 The vibration detection method can be applied to Figures 1 to 6 The vibration detection device 10 shown. Regarding the vibration detection method, firstly, step S100 is executed, and all the acceleration sensors 32 of the first detection module 24 of the vibration detection device 10 are driven by the driving motor 26 to stop at the corresponding test point P of the vibrating touch panel 14 at the same time. Then, step S102 is executed, and the piezoelectric element 22 of the vibrating touch panel 14 is triggered by the control circuit of the vibration detection device 10; the triggering time, triggering number and position of the triggered piezoelectric element 22 depend on the vibration mode provided by the vibrating touch panel 14. Next, step S104 is executed, and the vibration feedback parameters generated by each of the multiple test points P are detected separately and simultaneously by all the acceleration sensors 32. Finally, step S106 is executed, and the vibration detection device 10 outputs each vibration feedback parameter of the multiple test points P detected by all the acceleration sensors 32 for subsequent analysis.

[0061] In addition, step S200 can also be executed to stop the pressure sensor 42 of the second detection module 25 of the vibration detection device 10 at one of the test points P of the vibrating touch panel 14, and then step S202 is executed to gradually increase the external force applied by the pressure sensor 42 to the test point P until the piezoelectric element 22 of the vibrating touch panel 14 is triggered, thereby obtaining the force value of the pressure sensor 42 when generating a vibration feedback parameter at the test point P. Next, step S204 is executed to stop the pressure sensor 42 at another test point P of the vibrating touch panel 14 to obtain another force value of the pressure sensor 42 when generating a vibration feedback parameter at another test point P. Finally, step S206 is executed, and after the pressure sensor 42 has measured the force values ​​of all the test points P, the vibration detection device 10 outputs the force values ​​corresponding to each test point P of the vibrating touch panel 14 for subsequent analysis.

[0062] Regarding step S106 and step S200, the vibration detection method of the present invention replaces the first detection module 24 on the vibration detection device 10 with the second detection module 25 to switch between the two processes. The vibration detection method of the present invention can remove the first detection module 24 from the detection arm and then install the second detection module 25 on the detection arm; or the first detection module 24 and the second detection module 25 can be installed together on the turntable of the detection arm (not drawn in the figure), and the application of the first detection module 24 and the second detection module 25 can be switched by rotating the turntable. The vibration detection method of the present invention can also first drive the pressure sensor 42 to detect (that is, first perform steps S200, S202, S204, S2062), and then drive the acceleration sensor 32 to detect (that is, then perform steps S100, S102, S104, S106), and the order depends on actual needs. In addition, in step S100 and step S200 , the vibration detection device 10 can selectively utilize the positioning element 34 to abut against the test platform 38 or the vibrating touch panel 14 to provide positioning.

[0063] In summary, the vibration detection device and the vibration detection method of the present invention respectively design the acceleration sensor and the pressure sensor as two detection modules, which stop at the vibrating touch panel in turn to obtain the required vibration feedback parameters. The feature of the present invention is that multiple acceleration sensors are simultaneously pressed against multiple test points of the vibrating touch panel to obtain the vibration feedback parameters of all test points in a specific vibration mode in real time; the present invention also uses a test platform that can move quickly to adjust the position of the vibrating touch panel relative to the vibration detection device, and selects a high response frequency pressure sensor to stop at multiple test points of the vibrating touch panel in turn, and sequentially obtains the vibration feedback parameters of each test point in a specific vibration mode. Compared with the prior art, the vibration detection device and the vibration detection method of the present invention can accurately and quickly complete the vibration feedback parameters of all test points of the vibrating touch panel in a short time, and have better market competitiveness.
