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 an insulating (material) plate and a pressing component. The insulating plate is vertically and vertically positioned above the product placement platform. The pressing component is vertically and vertically positioned above the insulating 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. An insulating plate is lowered to contact the capacitive touch button products, and then a pressing element is lowered to press (or contact) the insulating plate, thereby indirectly pressing the button on the capacitive touch button products. The PCB adapter board receives the analog signal after the press (or contact) 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 signal is 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 insulating 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 pressing mechanism also includes a support plate and an annular frame; a first support column is fixedly installed at the top of the annular frame, and is fixed below the support plate at intervals through the first support column; the insulating plate is a fiberglass board or a transparent PC board; the insulating plate is fixedly installed below the annular frame, and forms a receiving area with the annular frame; the support plate is movable and height-adjustable, thereby driving the insulating plate to be movable and height-adjustable above the product placement platform; the pressing member is movable and height-adjustable below the support plate, and after the pressing member descends, it can enter the receiving area to press the insulating plate. This utility model, by making the support plate movable and height-adjustable, when the support plate moves up and down, drives the insulating plate to move up and down through the first support column and the annular frame, thereby achieving the movable and height-adjustable installation of the insulating plate above the product placement platform. When the support plate descends, it drives the insulating plate to descend, causing the insulating plate to press against the capacitive touch button product placed on the product placement platform, thus pressing the capacitive touch button product in place. By vertically and flexibly positioning the pressing element below the support plate, the pressing element can be lowered and enter the receiving area to press the insulating plate, thereby indirectly pressing the button on the capacitive touch button product.

[0008] Furthermore, the pressing mechanism also includes a first lifting drive component and a second lifting drive component. The first lifting drive component is used to drive the support plate to move up and down; the second lifting drive component is used to drive the pressing component to move up and down. Those skilled in the art can select the specific structure of the first lifting drive component and the second lifting drive component according to actual needs, so as to realize that the first lifting drive component drives the support plate to move up and down and the second lifting drive component drives the pressing component to move up and down. For example, a telescopic cylinder, etc., will not be described in detail here.

[0009] Furthermore, the pressing component is a metal plate (e.g., an aluminum plate), a conductive silicone layer, a conductive sponge layer, or a set of metal pressing heads. By utilizing a metal plate, a conductive silicone layer, a conductive sponge layer, or a set of metal pressing heads, the detection effect is improved by simulating a human hand indirectly pressing all the buttons on a capacitive touch button product in one go. Preferably, the metal pressing head assembly is a common capacitive touch test head.

[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 outer edge of the annular frame corresponds to the outer edge of the insulating plate; the insulating plate is adapted to the top surface of the product placement platform; and a blank area corresponding to the adapter groove is provided at the edge of the insulating plate. Considering that after the PCB adapter board is placed on the adapter groove, when the insulating plate descends to fit against the capacitive touch button product on the product placement platform, the PCB adapter board may affect the insulating plate, resulting in uneven fit between the insulating plate and the capacitive touch button product. This utility model avoids the presence of an "insulating plate" at the edge of the insulating plate by providing a blank area corresponding to the adapter groove, thus avoiding the influence of the PCB adapter board on the insulating plate. At the same time, due to the blank area, after the capacitive touch button product is connected to the PCB adapter board, the descending annular frame at the blank area can also press down on the PCB adapter board, improving the connection stability between the capacitive touch button product and the PCB adapter board.

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

[0013] 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 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.

[0014] Furthermore, the detection device for the capacitive touch button also includes a cover, which is fixedly mounted on the main body and covers the outside of the pressing mechanism; a product inlet / outlet is provided on the side wall of the cover near the transfer groove of the product placement platform. The cover protects the components of the pressing mechanism; the product inlet / outlet on the cover facilitates the placement of the capacitive touch button product onto the product placement platform, and after detection, the capacitive touch button product is removed through the product inlet / outlet.

[0015] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, the terms "first," "second," "third," etc., used in the specification and claims are only for the purpose of distinguishing the description of the same technical features and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated, nor necessarily the order of description or chronological sequence.

[0021] Example 1 This embodiment provides a detection device for capacitive touch buttons. Please refer to [link / reference]. Figures 1-3 This includes a product placement platform 1, a pressing mechanism 2, and a testing module 3. Please refer to [link / reference]. Figure 5The 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 12 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 12 is used for electrical connection to the capacitive touch button products placed on the product placement platform 1. Please refer to [link / reference]. Figure 4 , Figure 6 and Figure 7 The pressing mechanism 2 includes an insulating plate 21 and a pressing element 22. The insulating plate 21 is vertically and vertically positioned above the product placement platform 1. The lower surface of the insulating plate 21 is flat. After the insulating plate 21 is lowered, it can fit against the capacitive touch button product placed on the product placement platform 1 to press the capacitive touch button product in place. The pressing element 22 is vertically and vertically positioned above the insulating plate 21. After the pressing element 22 is lowered, it can press the insulating plate 21, thereby indirectly pressing the button on the capacitive touch button product and generating an analog signal that is fed back to the PCB adapter board 12. The test module 3 is electrically connected to the PCB adapter board 12. The test module 3 is used to test the capacitive touch button product. When the PCB adapter board 12 receives the pressed analog signal, it feeds back to the 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.

[0022] In this embodiment, please refer to Figure 4 , Figure 6 The pressing mechanism 2 also includes an annular frame 23 and a support plate 24. The annular frame 23 is adapted to the edge position of the upper surface of the insulating plate 21 (the outer edge of the annular frame 23 corresponds to the outer edge of the insulating plate 21). The insulating plate 21 is fixedly disposed below the annular frame 23 and encloses the annular frame 23 to form a receiving area 231. Please refer to... Figure 4 and Figure 6 A first support column 25 is fixedly disposed at the top of the annular frame 23, and the annular frame 23 is fixedly disposed below the bearing plate 24 via the first support column 25. (See also...) Figure 4 and Figure 6 The support plate 24 is movable and can be raised and lowered. When the support plate 24 is movable and lowered, the insulating plate 21 is moved and lowered through the first support column 25 and the annular frame 23, thereby realizing that the insulating plate 21 is movable and lowered above the product placement platform 1. After the support plate 24 lowers and drives the insulating plate 21 to lower, the insulating plate 21 fits against the capacitive touch button product placed on the product placement platform 1, thereby pressing the capacitive touch button product. The pressing member 22 is movable and lowered below the support plate 24 and above the receiving area 231. After the pressing member 22 lowers, it can enter the receiving area to press the insulating plate 21, thereby indirectly pressing the button on the capacitive touch button product.

[0023] In this embodiment, the insulating board 21 is a fiberglass board. In other embodiments, the insulating board may also be a transparent PCB board or a board made of insulating material.

[0024] In this embodiment, please refer to Figure 4 The bottom of the insulating plate 21 is provided with a guide post 212, please refer to [link / reference]. Figure 5 The product placement platform 1 is provided with guide holes 15 corresponding to the guide posts 212. When the insulating plate 21 descends, the guide posts 212 pass through the guide holes 15, which helps the insulating plate to stably fit with the capacitive touch button product placed on the product placement platform 1.

[0025] In this embodiment, refer to Figure 4 and Figure 6 The pressing element 22 is a metal plate (specifically an aluminum plate), and the shape of the metal plate is adapted to the inner circumference of the annular frame 23. After the metal plate descends, it enters the receiving area 231 to press the insulating plate 21, allowing all buttons of the capacitive touch button product to be pressed indirectly at once. In some other embodiments, the pressing element 22 is a set of metal pressing head assemblies (such as capacitive touch test heads commonly used in the art), each corresponding to a button of the capacitive touch button product. In some other embodiments, the pressing element 22 can also be a conductive silicone layer or a conductive sponge layer; by using a metal plate, a conductive silicone layer, a conductive sponge layer, or a set of metal pressing head assemblies to simulate a human hand indirectly pressing all buttons on the capacitive touch button product at once, the detection effect is improved.

[0026] For easier lifting and lowering of the drive plate 24, please refer to [link / reference]. Figure 4 The pressing mechanism 2 also includes a first lifting drive component 26, which is used to drive the support plate 24 to move up and down. In this embodiment, the first lifting drive component 26 is a telescopic cylinder. In other embodiments, those skilled in the art can also select other first lifting drive components 26 according to actual needs, as long as the first lifting drive component 26 can drive the support plate 24 to move up and down. This will not be elaborated here.

[0027] For easier operation of the pressing element 22, please refer to [link / reference]. Figure 4 The pressing mechanism 2 also includes a second lifting drive 27, which drives the pressing member 22 to move up and down. In this embodiment, the second lifting drive 27 consists of multiple small telescopic cylinders, which are fixedly mounted on the lower surface of the support plate 24. The pressing member 22 is connected to the output ends of the multiple telescopic cylinders, so that the multiple telescopic cylinders drive the pressing member 22 to move up and down. By driving the pressing member 22 to move up and down through the multiple telescopic cylinders, the pressing member 22 enters the receiving area and adheres to the pressing insulating plate 21, indirectly simulating the button on a capacitive touch button product.

[0028] In this embodiment, please refer to Figure 3 and Figure 5 The detection device for capacitive touch buttons also includes a main body base 4; a second support column 13 is fixedly installed at the bottom of the product placement platform 1, and the product placement platform 1 is spaced above the main body base 4 via the second support column 13. The main body base 4 has an internal cavity, and the test module 3 is installed 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, and the PCB adapter board 12 is electrically connected to the test module 3 via a conductive wire passing through the opening 41. Specifically, in this embodiment, please refer to... Figure 3 and Figure 5 A mounting plate 14 is detachably fixed to the top of the main body base 4, and a second support column 13 is fixed to the top of the mounting plate 14, thereby indirectly fixing it to the top of the main body base 4. The mounting plate 14 has through holes with corresponding openings 41, and the PCB adapter board 12 is electrically connected to the test module 3 through conductive wires passing through the through holes and openings 41.

[0029] In this embodiment, 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 24. The first lifting drive component 26 is fixedly installed above the fixing plate 5. The output end of the first lifting drive component 26 passes through the fixing plate 5 and is fixedly connected to the support plate 24 so as to drive the support plate 24 to perform lifting and lowering activities.

[0030] To prevent the capacitive touch button product from shifting during the process of the insulating plate 21 lowering and pressing down on the product after it has been placed on the product placement platform 1 and connected to the PCB adapter board 12, in some embodiments, a peelable limiting adhesive sticker (not shown) can be provided on the product placement platform 1. The limiting adhesive sticker is peelably and fixedly attached to the product placement platform 1, and its thickness is less than or equal to the thickness of the capacitive touch button product. The limiting adhesive sticker is used to restrict the position of the capacitive touch button product. For example, before the test begins, after the capacitive touch button product is placed on the product placement platform 1 and connected to the PCB adapter board 12, a peelable limiting adhesive sticker is attached to at least two sides (or multiple positions) of the capacitive touch button product. The limiting adhesive sticker prevents the capacitive touch button product from shifting during the subsequent process of the insulating plate 21 lowering and pressing down on the capacitive touch button product.

[0031] In this embodiment, please refer to Figure 5The adapter groove 11 is located at the edge of the top surface of the product placement platform 1. The insulating plate 21 is adapted to the top surface of the product placement platform 1 (the outer edge of the insulating plate 21 corresponds to the outer edge of the top surface of the product placement platform 1). Considering that the PCB adapter plate 12 is placed on the adapter groove 11, when the insulating plate 21 descends to contact the capacitive touch button product on the product placement platform 1, the PCB adapter plate 12 may affect the insulating plate 21, resulting in uneven contact between the insulating plate 21 and the capacitive touch button product. That is, considering that during the downward pressing of the insulating plate 21, the presence of the PCB adapter plate 12 may press against the PCB adapter plate 12, thus affecting the contact between the insulating plate 21 and the capacitive touch button product. In this embodiment, to avoid this situation, please refer to... Figure 7 The edge of the insulating plate 21 has a blank area 211 corresponding to the adapter groove 11. After the insulating plate 21 is lowered to fit with the capacitive touch button product, there is no insulating plate at the corresponding position on the adapter groove 11, which avoids the influence of the PCB adapter plate 12 on the insulating plate 21. Instead, due to the design of the blank area 211, after the capacitive touch button product is connected to the PCB adapter plate 12, during the process of the carrier plate 24 driving the annular frame 23 and the insulating plate 21 to descend, the "frame" of the annular frame 23 presses down on the PCB adapter plate 12, which improves the connection stability between the capacitive touch button product and the PCB adapter plate 12.

[0032] In this embodiment, please refer to Figure 1 and Figure 2 The detection device for capacitive touch buttons also includes a cover 6, which is fixed on the main body 4 and covers the outside of the pressing mechanism 2. A product inlet / outlet 61 is provided on the side wall of the cover 6 on the side of the adapter groove 11 near the product placement platform 1. The capacitive touch button product is placed on the product placement platform 1 through the product inlet / outlet 61 and connected to the PCB adapter board 12 in the adapter groove 11. After detection, the capacitive touch button product is taken out through the product inlet / outlet 61.

[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 7, 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 7 is fixedly mounted on the housing 6.

[0034] In this embodiment, please refer to Figure 1 and Figure 2 Handles 42 are fixedly hinged to both sides of the main body 4. The structure of the handles 42 facilitates the handling and movement of the capacitive touch button detection device of this embodiment.

[0035] In this embodiment, please refer to Figure 1 and Figure 2 The main body 4 is also equipped with a two-hand switch 43, which controls the operation of the first lifting drive component 26 and the second lifting drive component 27. The two-hand switch 43 requires both hands to press simultaneously. When activated, the operator must press both hands on the two-hand switch 43 to prevent hands from resting on the product placement platform 1 and to avoid injury from the insulating 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 26 to drive the support plate 24 to descend, thereby causing the insulating plate 21 to descend and contact the capacitive touch button product. It also controls the second lifting drive component 27 to drive the pressing component 22 to descend and press the insulating plate 21, thereby indirectly pressing the button on the capacitive touch button product. In this embodiment, the top of the fixing plate 5 is also equipped with a solenoid valve 28, which controls the operation of the first lifting drive component 26 and the second lifting drive component 27 through the two-hand switch 43 and the solenoid valve 28. In this embodiment, the main body 4 is also equipped with a master switch 44, which can stop the detection device of the capacitive touch button in this embodiment. In this embodiment, a power supply 29 is also provided on the top of the fixing plate to supply power to components such as the solenoid valve 28, the first lifting drive component 26, and the second lifting drive component 27.

[0036] The working process of the capacitive touch button testing 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 12. The two-hand switch 43 is pressed, causing the insulating plate 43 to descend and contact the capacitive touch button product placed on the product placement platform 1. The pressing member 22 then descends to press (or contact) the insulating plate 21, thereby indirectly pressing the button on the capacitive touch button product. The PCB adapter board 12 receives the analog signal after pressing (or contacting) and feeds it back to the test module 3. The test module 3 performs functional testing on the capacitive touch button product, such as determining whether the button touch signal is normal, and then outputs the test result, which is displayed on the test result display screen 7.

[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 insulating plate 21 is a plane, it can also contact and adhere to different capacitive touch button products. Thus, 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, 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.
