Description

Technical Field

[0001] This utility model relates to the field of capacitive touch button testing, and in particular to a testing device for capacitive touch buttons. Background Technology

[0002] Existing testing devices for capacitive (membrane) touch buttons typically require the design of specific grooves on the fixture body to meet the positioning requirements of different capacitive touch button products. When testing different capacitive touch button products, each product requires a dedicated fixture or jig, necessitating frequent changes to different fixtures or jigs to adapt to the testing of different capacitive touch button products. This consumes a significant amount of setup time, resulting in low testing efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a detection device for capacitive touch buttons, which can be applied to the detection of different capacitive touch button products, avoiding the problem that existing detection devices need to frequently change special fixtures to adapt to different capacitive touch button products, thus saving time and costs.

[0004] A testing device for capacitive touch buttons includes a product placement platform, a pressing mechanism, and a testing module. The top surface of the product placement platform is flat, and a recessed adapter groove is provided on one side of the top surface of the product placement platform. A PCB adapter board is fixedly installed in the adapter groove. The pressing mechanism includes a pressing plate, which is vertically and flexibly positioned above the product placement platform. An elastic conductive material layer is provided on the bottom surface of the pressing plate. The testing module is electrically connected to the PCB adapter board.

[0005] The present invention relates to a detection device for capacitive touch buttons. A product placement platform is used to place capacitive touch button products, and a PCB adapter board is used to electrically connect to the placed capacitive touch button products. The device involves placing the capacitive touch button products on the product placement platform, electrically connecting the capacitive touch button products to the PCB adapter board, and electrically connecting the PCB adapter board to the test module. A pressing plate is lowered to contact and press against the capacitive touch button products, using the elastic conductive material layer on the bottom surface of the pressing plate to press all buttons on the capacitive touch button products, simulating a human hand touching all buttons on the capacitive touch button products at once. The PCB adapter board receives the simulated signal after pressing (or contacting) and feeds it back to the test module. The test module is used to perform functional testing on the capacitive touch button products, such as determining whether the button touch signals are normal.

[0006] The capacitive touch button detection device of this utility model, because the product placement platform is designed with a planar structure, can be used to place different capacitive touch button products. Furthermore, because the bottom surface of the pressing plate is also planar, it can also contact and adhere to different capacitive touch button products. Therefore, it can be used for bonding, pressing and fixing different capacitive touch button products, avoiding the problem of existing detection devices requiring frequent replacement of special fixtures to adapt to different capacitive touch button products, thus saving time and costs.

[0007] Furthermore, the elastic conductive material layer is a conductive silicone layer. By providing a conductive silicone layer on the bottom surface of the pressing plate, when the pressing plate descends to adhere to and press against the capacitive touch button product, all buttons on the capacitive touch button product can be pressed using the conductive silicone layer on the bottom surface of the pressing plate, thus simulating a human hand touching all buttons on the capacitive touch button product at once. Of course, those skilled in the art can also choose other elastic conductive material layers according to actual needs.

[0008] Furthermore, the pressing mechanism also includes a support plate and a connecting plate; a first support column is fixedly installed on the top of the pressing plate, and is fixed below the connecting plate at intervals through the first support column; the connecting plate is fixedly installed below the support plate in a way that allows it to move left and right; the support plate is movable up and down, thereby driving the pressing plate to be movable up and down above the product placement platform. This invention, by designing the connecting plate to be movable left and right below the support plate, allows for left and right adjustment of the pressing plate's position, increasing its degree of freedom. Additionally, by making the support plate movable up and down, when the support plate moves up and down, the connecting plate and the first support column drive the pressing plate to move up and down, thereby enabling the pressing plate to be movable up and down above the product placement platform. When the support plate descends, it causes the pressing plate to descend, causing the pressing plate to press against the capacitive touch button product placed on the product placement platform, thus holding the capacitive touch button product in place. The elastic conductive material layer on the bottom surface of the pressing plate simulates the touch of the buttons on the capacitive touch button product.

[0009] Furthermore, the pressing mechanism also includes a first lifting drive component, which is used to drive the support plate to move up and down. Those skilled in the art can select the specific structure of the first lifting drive component according to actual needs, as long as it enables the first lifting drive component to drive the support plate to move up and down; for example, a telescopic cylinder can be used, which will not be elaborated further here.

[0010] Furthermore, the detection device for the capacitive touch button also includes a limiting adhesive sticker, which is peelably attached to the product placement platform. The thickness of the limiting adhesive sticker is less than or equal to the thickness of the capacitive touch button product. This invention, by using the limiting adhesive sticker, prevents the capacitive touch button product from shifting after it is placed on the product placement platform (for example, the limiting adhesive sticker is attached to both sides of the placed capacitive touch button product). In addition, the limiting adhesive sticker can be peeled off and replaced at any time, changing its position on the product placement platform, making it suitable for limiting the position of different capacitive touch button products.

[0011] Furthermore, the adapter groove is located at the edge of the top surface of the product placement platform; the pressing plate is adapted to the top surface of the product placement platform; and the bottom edge of the pressing plate has a corresponding slot for the adapter groove. Considering that after the PCB adapter plate is placed on the adapter groove, when the pressing plate descends to contact the capacitive touch button product on the product placement platform, the PCB adapter plate may affect the pressing plate, resulting in uneven contact between the pressing plate and the capacitive touch button product, affecting the pressing contact effect between the elastic conductive material layer and the button on the capacitive touch button product. This utility model provides a corresponding slot for the adapter groove at the edge of the pressing plate. This slot can "accommodate" the PCB adapter plate, avoiding the influence of the PCB adapter plate on the pressing plate. At the same time, due to the setting of the slot, after the capacitive touch button product is connected to the PCB adapter plate, when the pressing plate descends, the position of the slot can also be used to press the PCB adapter plate, improving the connection stability between the capacitive touch button product and the PCB adapter plate.

[0012] Furthermore, the detection device for the capacitive touch button also includes a main body base; a second support column is provided at the bottom of the product placement platform, and is spaced above the main body base through the second support column; the main body base has an internal cavity, and the test module is disposed inside the main body base; an opening communicating with the interior of the main body base is provided on the top of the main body base near the adapter slot, and the PCB adapter board is electrically connected to the test module through a conductive wire passing through the opening.

[0013] Furthermore, a mounting plate is fixedly mounted on the top of the main body base, which can be moved left and right, and the second support column is fixedly mounted on the top of the mounting plate; the mounting plate has a through hole corresponding to the opening of the main body base, and the PCB adapter board is electrically connected to the test module through a conductive wire passing through the through hole and the opening. This invention, by designing the mounting plate to be fixedly mounted on the top of the main body base, allows for left and right adjustment of the product placement platform's position, increasing the degree of freedom of the product placement platform.

[0014] Furthermore, the detection device for the capacitive touch button also includes a fixing plate, and a third support column is fixedly installed on the top of the main body. The fixing plate is fixedly installed on the top of the third support column and is located above the support plate. The first lifting drive component is fixedly installed above the fixing plate, and the output end of the first lifting drive component passes through the fixing plate and is fixedly connected to the support plate. The fixing plate ensures that the pressing mechanism is positioned entirely above the product placement platform.

[0015] Furthermore, the support plate is provided with a first connecting groove extending to the left and right, and the first connecting groove is provided with a first spiral fixing member, which passes through the first connecting groove and is spirally fixedly connected to the connecting plate; the mounting plate is provided with a second connecting groove extending to the left and right, and the second connecting groove is provided with a second spiral fixing member, which passes through the second connecting groove and is spirally fixedly connected to the top of the main body.

[0016] Furthermore, the capacitive touch button testing device also includes a test result display screen, which is electrically connected to the testing module and is used to display the test results of the testing module. After testing the capacitive touch button product, the testing module feeds back the test results to the test result display screen for easy observation of whether the capacitive touch button product meets the required requirements, such as whether the button touch signal is normal.

[0022] Example 1 This embodiment provides a detection device for capacitive touch buttons. Please refer to [link / reference]. Figure 1 and Figure 2 This includes a product placement platform 1, a pressing mechanism 2, and a testing module 3. Please refer to [link / reference]. Figure 1 and Figure 3The top surface of the product placement platform 1 is flat. A recessed adapter groove 11 is provided on one side of the top surface of the product placement platform 1, and a PCB adapter board (not shown) is fixedly installed in the adapter groove 11. The product placement platform 1 is used to place capacitive touch button products, and the PCB adapter board is used for electrical connection to the capacitive touch button products placed on the product placement platform 1. Please refer to [link / reference]. Figure 1 , Figures 4-6 The pressing mechanism 2 includes a pressing plate 21. The bottom surface of the pressing plate 21 is provided with an elastic conductive material layer (specifically, a conductive silicone layer, not shown in the figure). The pressing plate 21 is vertically and vertically positioned above the product placement platform 1. The bottom surface of the pressing plate 21 is flat (i.e., the bottom surface of the elastic conductive material layer is flat). After the pressing plate 21 descends, it can adhere to the capacitive touch button product placed on the product placement platform 1, pressing the capacitive touch button product in place. The elastic conductive material layer on the bottom surface of the pressing plate 21 presses all the buttons on the capacitive touch button product, simulating a human hand simultaneously touching all the buttons on the capacitive touch button product, generating an analog signal feedback to the PCB adapter board. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 Test module 3 is electrically connected to the PCB adapter board. Test module 3 is used to test capacitive touch button products. When the PCB adapter board receives the analog signal of being pressed, it feeds back to test module 3 for functional testing, analyzing whether the touch signal of the button on the capacitive touch button product is normal and other functional analyses.

[0023] In this embodiment, please refer to Figures 4-6 The pressing mechanism 2 also includes a support plate 22 and a connecting plate 23. Multiple first support columns 24 are fixedly mounted on the top of the pressing plate 21, and the pressing plate 21 is fixedly positioned below the connecting plate 23 at intervals via the first support columns 24. The connecting plate 23 is detachably and movably fixed below the support plate 22, so that by adjusting the position of the connecting plate 23 left and right, the position of the pressing plate 21 can be adjusted left and right, so that the pressing plate 21 corresponds to the area above the capacitive touch button product placed on the product placement platform 1. Please refer to [link / reference]. Figure 1 , Figures 4-6 The support plate 22 is movable and can be raised and lowered. When the support plate 22 is movable and lowered, the pressing plate 21 is moved and lowered through the connecting plate 23 and the first support column 24, so that the pressing plate 21 can be raised and lowered and set above the product placement platform 1. After the support plate 22 is lowered and the pressing plate 21 is lowered, the pressing plate 21 will press the capacitive touch button product placed on the product placement platform 1 to press the capacitive touch button product. The elastic conductive material layer on the bottom surface of the pressing plate 21 simulates the button on the capacitive touch button product.

[0024] To facilitate the detachable and laterally movable fixing of the connecting plate 23 below the support plate 22, in this embodiment, please refer to... Figure 5 and Figure 6 The support plate 22 is provided with a first connecting groove 222 extending left and right. A first spiral fastener 223 is provided in the first connecting groove 222. The first spiral fastener 223 passes through the first connecting groove 222 and is spirally fixed to the connecting plate 23. When it is necessary to adjust the left and right position of the connecting plate 23, the position of the first spiral fastener 223 in the first connecting groove 222 is adjusted left and right by loosening the first spiral fastener 223 and then tightening the first spiral fastener 223.

[0025] For easier lifting and lowering of the drive plate 22, please refer to [link / reference]. Figure 1 and Figure 4 The pressing mechanism 2 also includes a first lifting drive component 25, which is used to drive the support plate 22 to move up and down. In this embodiment, the first lifting drive component 25 is a telescopic cylinder. In other embodiments, those skilled in the art can also select other first lifting drive components 25 according to actual needs, as long as the first lifting drive component 25 can drive the support plate 22 to move up and down. This will not be elaborated here.

[0026] In this embodiment, please refer to Figure 1 and Figure 2 The detection device for capacitive touch buttons also includes a main body base 4; please refer to Figure 1 and Figure 3 The bottom of the product placement platform 1 is provided with a second support column 12, and the product placement platform 1 is spaced above the main body base 4 through the second support column 12. The main body base 4 has an internal cavity, and the test module 3 is placed inside the main body base 4; the top of the main body base 4 has an opening 41 communicating with the interior of the main body base 4 on the side near the adapter groove 11, and the PCB adapter board is electrically connected to the test module 3 through the opening 41 via a conductive wire. Specifically, in this embodiment, please refer to Figure 1 and Figure 3 A mounting plate 13 is detachably and movable to the left and right on the top of the main body base 4. The second support column 12 is fixedly mounted on the top of the mounting plate 13, thereby indirectly fixing the product placement platform 1 on the top of the main body base 4. The mounting plate 13 has a through hole 131 corresponding to the opening 41 of the main body base 4. The PCB adapter board is electrically connected to the test module 3 through conductive wires passing through the through hole 131 and the opening 41.

[0027] To facilitate the detachable and laterally movable mounting plate 13 fixedly mounted on the top of the main body 4, in this embodiment, please refer to... Figure 3The mounting plate 13 is provided with a second connecting groove 132 extending left and right. A second spiral fastener 133 is provided in the second connecting groove 132. The second spiral fastener 133 passes through the second connecting groove 132 and is spirally fixed to the top of the main body base 4. When it is necessary to adjust the left and right position of the mounting plate 13, the position of the second spiral fastener 133 in the second connecting groove 132 is adjusted left and right by loosening the second spiral fastener 133 and then tightening the second spiral fastener 133.

[0028] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The detection device for the capacitive touch button also includes a fixing plate 5. A third support column 51 is fixedly installed on the top of the main body 4. The fixing plate 5 is fixedly installed on the top of the third support column 51 and is located above the support plate 22. The first lifting drive component 25 is fixedly installed above the fixing plate 5. The output end of the first lifting drive component 25 passes through the fixing plate 5 and is fixedly connected to the support plate 22 so as to drive the support plate 22 to perform lifting and lowering activities.

[0029] In this embodiment, please refer to Figure 4 and Figure 6 The end of the bearing plate 22 is also provided with a sleeve 221. The bearing plate 22 is sleeved on the third support column 51 through the sleeve 221. When the first lifting drive component 25 drives the bearing plate 22 to make lifting movements, the bearing plate 22 can make stable lifting movements along the third support column 51.

[0030] To prevent the capacitive touch button from shifting during the pressing process of the pressure plate 21 pressing down on the product platform 1 after it has been placed on the product platform 1 and connected to the PCB adapter board, in some embodiments, a peelable limiting adhesive sticker (not shown) can be provided on the product platform 1. The limiting adhesive sticker is peelably and fixedly attached to the product platform 1, and its thickness is less than or equal to the thickness of the capacitive touch button. The limiting adhesive sticker is used to restrict the position of the capacitive touch button. For example, before the test begins, after the capacitive touch button is placed on the product platform 1 and connected to the PCB adapter board, the peelable limiting adhesive sticker is attached to at least two sides (or multiple positions) of the capacitive touch button on the product platform 1. The limiting adhesive sticker prevents the capacitive touch button from shifting during the subsequent pressing process of the pressure plate 21 pressing down on the capacitive touch button.

[0031] In this embodiment, please refer to Figure 3The adapter groove 11 is located at the edge of the top surface of the product placement platform 1, and the pressing plate 21 is adapted to the top surface of the product placement platform 1 (i.e., the outer edge of the pressing plate 21 corresponds to the outer edge of the product placement platform 1). Considering that after the PCB adapter plate is placed on the adapter groove 11, when the pressing plate 21 descends to fit against the capacitive touch button product on the product placement platform 1, the PCB adapter plate may affect the pressing plate 21, resulting in uneven bonding between the pressing plate 21 (the elastic conductive material layer on the bottom surface of the pressing plate 21) and the capacitive touch button product. That is, considering that during the pressing process of the pressing plate 21, the presence of the PCB adapter plate may press against the PCB adapter plate (for example, the PCB adapter plate is slightly higher than the top surface of the product placement platform 1 in the adapter groove 11), thus affecting the bonding between the pressing plate 21 and the capacitive touch button product. In this embodiment, to avoid this situation, please refer to... Figure 6 The bottom edge of the pressing plate 21 has a corresponding slot 211 for the adapter groove 11. After the pressing plate 21 descends to fit with the capacitive touch button product, there is no elastic conductive material layer on the corresponding position of the adapter groove 11. Instead, the slot 211 is used to "accommodate" the top of the PCB adapter plate, avoiding the top of the PCB adapter plate from affecting the pressing plate 21. Moreover, due to the design of the slot 211, after the capacitive touch button product is connected to the PCB adapter plate, the PCB adapter plate is pressed down by the slot 211 during the process of the pressing plate 21 descending driven by the carrier plate 22, which improves the connection stability between the capacitive touch button product and the PCB adapter plate.

[0032] In this embodiment, to improve the installation stability of the fixing plate 5, please refer to... Figure 1 and Figure 2 The left and right sides of the fixing plate 5 are also fixedly connected to the main body base 4 through the support plate 52.

[0033] In this embodiment, please refer to Figure 1 and Figure 2 The detection device for the capacitive touch button also includes a detection result display screen 6, which is electrically connected to the test module 3 and is used to display the detection results of the test module 3. In this embodiment, the detection result display screen 6 is mounted on the side of the support plate 52.

[0034] In this embodiment, please refer to Figure 1 and Figure 2 The main body 4 has hand holes 42 on both sides. The hand hole 42 structure facilitates the handling and transfer of the detection device of the capacitive touch button in this embodiment.

[0035] In this embodiment, please refer to Figure 1 and Figure 2The main body 4 is also equipped with a two-hand switch 43, which controls the operation of the first lifting drive component 25. The two-hand switch 43 requires simultaneous pressing with both hands. When activated, the operator must press the two-hand switch 43 with both hands to prevent hands from resting on the product placement platform 1 and to avoid injury from the pressing plate 21 pressing down on the operator's hands. Furthermore, when the two-hand switch 43 is activated, it controls the first lifting drive component 25 to drive the support plate 22 downwards, thereby causing the pressing plate 21 to descend and press against the capacitive touch button product. The elastic conductive material layer on the bottom surface of the pressing plate 21 presses all the buttons on the capacitive touch button product, simulating a human hand touching all the buttons on the capacitive touch button product at once. In this embodiment, the top of the fixing plate 5 is also equipped with a solenoid valve 26, which controls the operation of the first lifting drive component 25 through the two-hand switch 43 and the solenoid valve 26. In this embodiment, the main body 4 is also equipped with a master switch 44, which can stop the capacitive touch button detection device of this embodiment. In this embodiment, the main body 4 is also equipped with a power supply 27 for supplying power to components such as the solenoid valve 26 and the first lifting drive component 25.

[0036] The working process of the capacitive touch button detection device in this embodiment is as follows: The capacitive touch button product is placed on the product placement platform 1, and electrically connected to the PCB adapter board. The two-hand switch 43 is pressed, causing the pressing plate 21 to descend and press against the capacitive touch button product placed on the product placement platform 1. The elastic conductive material layer on the bottom surface of the pressing plate 21 presses all the buttons on the capacitive touch button product, simulating a human hand touching all the buttons on the capacitive touch button product at once. The PCB adapter board receives the simulated signal after pressing (or contacting) and feeds it back to the test module 3. The test module 3 performs functional tests on the capacitive touch button product, such as determining whether the button touch signal is normal, and then outputs the results to the test result display screen 6.

[0037] The capacitive touch button detection device of this embodiment, because the product placement platform 1 is designed with a planar structure, can be used to place different capacitive touch button products. Furthermore, because the bottom surface of the pressing plate 21 is a plane, it can also contact and adhere to different capacitive touch button products. Thus, it can be used for the bonding, pressing and fixing of different capacitive touch button products, avoiding the problem of existing detection devices requiring frequent replacement of special fixtures to adapt to different capacitive touch button products, saving time and costs.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
