Description

Technical Field

[0001] This utility model belongs to the technical field of button detection equipment, specifically relating to a button device for detecting button effects in TVs. Background Technology

[0002] Before leaving the factory, TV products need to have their TV buttons tested. The traditional method of testing TV buttons is to manually test whether the corresponding button positions are functional. However, manual testing has certain shortcomings: for example, the force applied during manual testing is uncontrollable, the button positions are incompatible, resulting in inaccurate test results. Moreover, long-term manual testing consumes a lot of human energy. With the continuous progress of industrialization, we now propose a device that can effectively and quickly test TV buttons.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides the following technical solution: a button device for detecting button effects in TVs, including a first base 1 and a second base 2. The second base 2 is fixedly installed on the push end of the device. A button assembly 3 and a pressing cylinder 4 are respectively installed at both ends of the first base 1. A fiber optic sensor 5 is installed on the side of the button assembly 3 at one end of the first base 1. A column 6 is installed at the top of the second base 2. A connecting plate 7 is installed at the top of the column 6. A slider 8 is installed on the side of the pressing cylinder 4. A slide rail 9 is installed on the side of the column 6. The slider 8 is slidably connected to the slide rail 9. The telescopic end of the pressing cylinder 4 is connected to the connecting plate 7.

[0018] In this embodiment, the button assembly 3 includes a fixed base 31. The surface of the fixed base 31 is provided with a plurality of through holes 32. A pressing rod 33 is inserted into each through hole 32. A top cover 34 and a bottom cover 35 are respectively fixedly installed at the top and bottom ends of the fixed base 31 by bolts. The surfaces of the top cover 34 and the bottom cover 35 are respectively provided with a first opening 36 and a second opening 37 corresponding to the through holes 32. The two ends of the pressing rod 33 are inserted and connected to the first opening 36 and the second opening 37, and one end extends to the top of the top cover 34 and is connected to the pressing head 38. A spring 39 is provided in the through hole 32 and is sleeved on the outside of the pressing rod 33.

[0019] Specifically, since the second base 2 is fixedly set, when the telescopic end of the pressing cylinder 4 moves telescopically, the pressing cylinder 4 will drive the first base 1 to move accordingly. At this time, the stability of the movement of the first base 1 can be improved under the action of the slide rail 9 and the slider 8. When the first base 1 moves, it will drive the pressing head 38 to contact the button area of ​​the TV. Thus, the pressing head 38 will cover the button area of ​​the TV by several pressing heads 38, thereby realizing the button detection requirements of TVs of different sizes. When the pressing head 38 detects the button, the spring 39 can buffer the pressing force, thereby avoiding hard contact between the pressing head 38 and the TV, which would cause damage to the TV.

[0020] In this embodiment, an annular hole 10 is provided at one end of the first base 1, the bottom cover 35 is installed at one end of the first base 1 and the pressing rod 33 is disposed in the annular hole 10.

[0021] Specifically, through the annular hole 10, when the pressing head 38 presses on the button, one end of the pressing rod 33 will pass through the second opening 37 and extend into the annular hole 10. Thus, the annular hole 10 avoids obstructing the movement of the pressing rod 33, thereby facilitating the detection of the TV button.

[0022] In this embodiment, an annular limiting block 310 is provided on the surface of the pressing rod 33. The two ends of the spring 39 abut against the annular limiting block 310 and the bottom cover 35 respectively. The diameter of the annular limiting block 310 matches the diameter of the through hole 32. The diameters of the first opening 36 and the second opening 37 are the same and match the diameter of the pressing rod 33. When the spring 39 is in the initial state, the annular limiting block 310 is in close contact with the top cover 34.

[0023] Specifically, the annular limiting block 310 improves the stability of the pressing rod 33 moving within the through hole 32. When the pressing head 38 contacts and presses the button, the pressing rod 33 moves within the first opening 36 and the second opening 37 under the action of the annular limiting block 310, with one end extending through the second opening 37 into the annular hole 10. At the same time, the annular limiting block 310 compresses the spring 39. Under the buffering effect of the spring 39, the pressing head 38 does not make hard contact with the TV, thus avoiding damage to the TV. This detection method makes the pressing force during button detection controllable, which is beneficial to improving the detection quality.

[0024] Working principle: When performing button detection on a TV, the device first needs to be positioned by a vision module, and then the TV position is detected by the delay of the fiber optic sensor 5. Since the second base 2 is fixedly installed on the pushing end of the device, the device is pushed to the detection area through the pushing end. The pressing cylinder 4 drives the first base 1 to move, so that the button assembly 3 can detect the TV buttons. Several pressing heads 38 cover the button area, thereby effectively expanding the button range and making the button range compatible with the button detection needs of different specifications of TVs. Moreover, the spring 39 can play a buffering role to avoid hard contact between the pressing head 38 and the TV surface, which would damage the TV, thus protecting the TV. The force of the device for TV button detection is controllable and can be compatible with the button detection needs of different specifications of TVs, while reducing labor costs.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
