[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0028] Embodiments of the present disclosure are described below. However, it should be understood that the disclosed embodiments are merely examples, and other embodiments may take various alternative forms. The drawings are not necessarily drawn to scale; certain features may be exaggerated or minimized to show the details of specific components.

The combination of features shown provides representative embodiments for typical applications. However, various combinations and modifications of features consistent with the teachings of the present disclosure may be desirable for certain specific applications or embodiments.

[0029] In the present application, relational terms, such as first and second, etc., are only used to distinguish an entity or action from another entity or action, and do not necessarily require or imply any actual such relationship or order between such entities or actions. The term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements do not only include these elements, but also may include other elements that are not explicitly listed or inherent to such processes, methods, articles or equipment. In the absence of more constraints, the element with "comprising" in front does not exclude the presence of other identical elements in the process, method, article or equipment including the element. The term "and / or" means that any one of the listed items can be adopted by itself when used to list two or more items, or any combination of two or more of the listed items can be adopted.

[0030] Based on the above purpose, a first aspect of an embodiment of the present invention provides an embodiment of a detection device for a knob button.

[0031] like Figure 1 As shown, the detection device specifically includes: a detection tooling board 100 and a detection terminal 110 connected to the detection tooling board 100, the detection tooling board 100 includes an MCU chip 101, when testing the knob button function, the tested knob button is connected to the detection tooling board 100 through a connecting cable, the MCU chip receives the rotation information of the knob button, and converts the rotation information into an operation instruction, and sends the operation instruction to the detection terminal; the detection terminal is used to perform visual operations according to the operation instructions, and the visual operations correspond one-to-one to the operation instructions.

[0032] Specifically, the detection terminal may be a computer with a display, a laptop, an all-in-one machine or other equipment, and the detection tooling board is powered by a power supply device or the detection terminal.

[0033] The communication between the MCU (Microcontroller Unit) chip and the detection terminal can be realized by a network or a circuit. The communication between the knob button to be tested and the MCU chip can be realized by a circuit.

[0034] Connect each pin of the tested knob button to the detection pin of the MCU chip. The MCU chip converts the received rotation information, such as clockwise rotation or counterclockwise rotation, into an operation instruction recognizable by the detection terminal and sends it to the detection terminal. After receiving the operation instruction, the detection terminal calls the operation instruction through the pre-configured file and the running interface to perform visual operations. For example, a digital switching script is pre-set. When the knob rotates clockwise, if the rotation function of the tested knob button is good, the number displayed on the detection terminal page will change from large to small or from small to large. If the rotation function of the tested knob button is bad, the number displayed on the detection terminal page will not change, so as to detect the quality of the rotation function of the knob button. The above example of digital change is only one optional way of visual operation. It can also be based on other ways of visual operation, such as switching pictures, to judge the quality of the rotation function of the knob button.

[0035] The size of the inspection tooling plate is determined by the size of each component thereon, and the size is controllable without causing waste of space.

[0036] By detecting the tooling board and the detection terminal connected to the detection work board, separate detection of the knob button before and after being fixed to the front shell of the display is achieved. The test method based on the above detection device is flexible, versatile, easy to operate and has intuitive results.

[0037] In some embodiments, the detection tooling board also includes an electroluminescent element and a power supply device, and the electroluminescent element, the power supply device and the knob button are connected in series; when the knob button is in the trigger position, the power supply device and the electroluminescent element are in a connection state, and when the knob button is in the cut-off position, the power supply device and the electroluminescent element are in an open circuit state.

[0038] The power supply device can be a power supply arranged on the detection tooling board, or a power supply located outside the detection tooling board. Preferably, the electroluminescent element is powered by the detection terminal. When the knob button is pressed to the trigger position, the knob button puts the power supply device and the electroluminescent element in a conductive state. When the knob button is in the cut-off position, the power supply device and the electroluminescent element are in an open circuit state, wherein the electroluminescent element includes a light-emitting diode, a light-emitting triode, etc. Taking the light-emitting diode as an example, when the knob to be tested is pressed to the cut-off position, the power supply device supplies power to the light-emitting diode, and the positive and negative poles of the light-emitting diode are turned on. If the light-emitting diode is lit, it means that the key function of the knob button to be tested is good. If the light-emitting diode is not lit, it means that the key function of the knob button to be tested is not good, thereby detecting the quality of the key function of the knob to be tested.

[0039] In some embodiments, the detection tooling board includes a USB interface, and the detection tooling board is connected to the detection terminal via the USB interface.

[0040] In some embodiments, the detection tooling board includes a power supply circuit, the USB interface is connected to the MCU chip through the power supply circuit, and the power supply circuit is used for communication between the MCU chip and the detection terminal. The detection tooling board includes a USB interface, the USB interface is connected to the MCU chip on the detection tooling board, and the detection terminal is connected to the USB interface through a USB cable, thereby connecting to the MCU chip.

[0041] like Figure 2 The figure shows a schematic diagram of the connection structure of the detection tooling board.

[0042] exist Figure 2 In the test, the MCU chip is selected as the SN8P212 series chip, the USB interface includes the positive power pin VDD, the negative power pin VSS, the positive data pin D+ and the negative data pin D-; the tested knob button includes the first pin K1, the second pin K2, the third pin K3 and the fourth pin K4. K3 of the tested knob button realizes the power supply function, the rotation function of the tested knob button is realized by the contact between K1 or K2 and K3, and the key function of the tested knob button is realized by the contact between K4 and K3.

[0043] The positive power pin VDD of the USB interface, the negative power pin VSS of the USB interface, the positive data pin D+ of the USB interface, the negative data pin D- of the USB interface, the first pin K1 of the knob button under test is connected to the detection pin P1.2 of the chip, the second pin K2 of the knob button under test is connected to the detection pin P1.1 of the chip, the negative power pin VSS of the USB interface is grounded, and the positive power pin VDD of the USB interface is connected to the third pin K3 of the knob button under test.

[0044] By pre-programming the SN8P212X series chips, after the detection terminal powers on the detection tooling board through the USB interface, the SN8P212X receives the rotation information of the knob button through the detection pins P1.2 and P1.1, forms different coding sequences based on the rotation information, and converts them into operation instructions recognizable by the detection terminal. For example, when the knob is rotated clockwise, it is converted into a "page flipping down or moving downward" instruction, and when the knob button is rotated counterclockwise, it is converted into a "page flipping up or moving the page upward" instruction. The quality of the rotation function of the knob button under test is detected by detecting whether the terminal performs corresponding operations according to the converted operation instructions.

[0045] Furthermore, the electroluminescent element uses a light-emitting diode, one end of the light-emitting diode is connected to the knob button K4 under test, and the other end is grounded. When the knob button under test is not pressed or is not pressed to the trigger position, the light-emitting diode does not receive the power supply voltage transmitted through the USB interface, and the positive and negative poles of the light-emitting diode are not conductive, so it is in a dark state. When the knob button under test is pressed to reach the trigger position, that is, K4 is in contact with K3, the light-emitting diode receives the power supply voltage transmitted through the USB interface, and the positive and negative poles of the light-emitting diode are conductive, so it is in a lit state. Therefore, the key function of the knob button under test is checked by whether the light-emitting diode is lit after the knob button under test is pressed to the trigger position.
