Technical Field
[0001] This utility model relates to the field of remote control technology, and in particular to a device for testing the buttons on a television remote control. Background Technology
[0002] After the production of TV remote controls, key indicators such as the sensitivity, pressing life, and rebound performance of silicone buttons need to be tested. Existing testing methods mostly rely on manual pressing, which not only requires staff to operate each button one by one, but is also time-consuming, labor-intensive, and inefficient, making it difficult to meet the needs of mass production. Furthermore, inconsistent pressing pressure and frequency can lead to large errors in test data, failing to accurately reflect the true quality of the buttons.
[0003] While some simple mechanical testing devices can replace manual labor, they have significant drawbacks: First, they lack an adaptive clamping mechanism, are only compatible with a single-size remote control, and require readjustment of the clamps when changing models, making the operation cumbersome. Second, the pressing components are mostly rigid structures without cushioning design, which can easily damage the buttons or shell due to excessive pressure. Furthermore, the contact arrangement and button matching are poor, leading to missed or incorrect tests, which seriously affects the accuracy and reliability of the test and makes it difficult to meet the requirements of high-quality production testing. This also brings certain adverse effects to the user experience. To address the shortcomings of existing technologies, we propose a TV remote control button testing device. Utility Model Content
[0004] The main objective of this invention is to provide a TV remote control button testing device, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A TV remote control button testing device includes a base. A servo motor is detachably connected to one side of the base. A rotating rod is detachably connected to the output shaft of the servo motor, and a first bevel gear is fixedly connected to the outer surface of the rotating rod. Second bevel gears mesh on both sides of the first bevel gear, and a threaded rod is fixedly connected to one end of each second bevel gear. A moving block is threadedly connected to the outer surface of the threaded rod, and a connecting clamp is fixedly connected to the upper end of the moving block. An anti-slip plate is detachably connected to one side of the connecting clamp. The remote control body is placed on the base, and the surface of the remote control body has multiple silicone buttons. The corners of the base surface are all fixedly connected. The device is fixedly connected to multiple support columns. A first connecting block is fixedly connected to the upper end of each support column, and a top plate is fixedly connected between the multiple first connecting blocks. An electric push rod is detachably connected to the upper end of the top plate. The output end of the electric push rod passes through the top plate and is fixedly connected to a second connecting block. A connecting plate is detachably connected to the lower end of the second connecting block by bolts. Two fixing boxes are symmetrically fixed to the lower end of the connecting plate. Two springs are detachably connected inside the fixing boxes, and one end of each spring abuts against a limit plate. A connecting column is fixedly connected to the lower end of the limit plate. A detection plate is fixedly connected to the lower end of the connecting column, and multiple detection contacts are detachably connected to the lower end of the detection plate.
[0007] Preferably, the anti-slip plate has uniformly distributed anti-slip textures on the side away from the connecting clamp, and the anti-slip plate is made of nitrile rubber. The base surface has a guide groove adapted to the moving block, the bottom of the moving block is embedded in the guide groove and slides in cooperation with the guide groove, and the length direction of the guide groove is consistent with the axial direction of the threaded rod.
[0008] Preferably, the inner wall of the fixing box is provided with a limiting groove that is adapted to the limiting plate. The limiting plate and the limiting groove are slidably engaged. One end of the spring is fixedly connected to the inner top wall of the fixing box, and the other end of the spring abuts against the upper end face of the limiting plate. The two springs are symmetrically distributed inside the fixing box, and the connecting post penetrates the inner bottom wall of the fixing box.
[0009] Preferably, the detection contact is made of soft silicone material, and the lower end face of the detection contact has an arc-shaped structure. The arrangement of multiple detection contacts at the lower end of the detection plate corresponds one-to-one with the arrangement of multiple silicone buttons on the surface of the remote control body, and the diameter of a single detection contact is not greater than the diameter of the corresponding silicone button.
[0010] Preferably, the base is fixedly connected to four anti-slip feet, which are located at the four corners of the base bottom. The lower end of the anti-slip feet is provided with anti-slip protrusions. There are four support columns, which correspond one-to-one with the four corners of the base surface. The support columns are fixed to the first connecting block and the top plate by welding.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This TV remote control button testing device uses a servo motor to drive a bevel gear transmission to rotate a threaded rod. Combined with the sliding limit of the moving block and guide groove, it enables adaptive clamping of remote control bodies of different sizes via a connecting clamping plate and an anti-slip plate. The nitrile rubber anti-slip plate combines elasticity and wear resistance, preventing damage to the remote control shell during clamping and improving clamping stability through its anti-slip texture. This effectively solves the problem of remote control misalignment leading to inaccurate testing in traditional methods. Furthermore, it eliminates the need for manual fixing, significantly reducing labor costs and improving the efficiency and reliability of single tests. It is suitable for batch testing scenarios of various specifications of TV remote controls.
[0013] This TV remote control button testing device uses a symmetrically arranged spring and limiting plate to form an elastic buffer structure. When the electric push rod drives the detection contact to press the silicone button, the spring can absorb excessive pressure through elastic deformation, ensuring that the detection contact always applies a constant and gentle force to the button. This avoids hard contact that could damage the button and ensures the remote control's reusability after testing. In addition, the detection contact and silicone button are arranged one-to-one and use a soft silicone arc design, which can accurately match the button position and increase the contact area, ensuring that each button can be pressed evenly. This significantly improves the accuracy of test parameters such as button sensitivity and lifespan, providing precise data support for remote control quality testing. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a TV remote control button testing device includes a base 1. A servo motor 2 is detachably connected to one side of the base 1 via bolts. The output shaft of the servo motor 2 is detachably connected to a rotating rod 3 via a coupling. A first bevel gear 4 is fixedly connected to the outer surface of the rotating rod 3. Second bevel gears 5 mesh on both sides of the first bevel gear 4. A threaded rod 6 is fixedly connected to the end of the second bevel gear 5 away from the first bevel gear 4 via welding. The end of the threaded rod 6 away from the second bevel gear 5 is rotatably connected to the inner wall of the base 1 via a bearing, ensuring that the threaded rod 6 can rotate stably around its own axis. A moving block 7 is threadedly connected to the outer surface of the threaded rod 6. A connecting clamp 8 is fixedly connected to the upper end of the moving block 7. An anti-slip plate 9 is detachably connected to the side of the connecting clamp 8 near the remote control body 10. The remote control body 10 is placed on the base 1. Multiple silicone buttons 11 are integrally formed on the surface of the remote control body 10. The remote control body 10 can be clamped and fixed by the cooperation of the connecting clamp 8 and the anti-slip plate 9. Multiple buttons 11 are fixedly connected to the corners of the surface of the base 1 via welding. A support column 12 is supported, and a first connecting block 13 is fixedly connected to the upper end of the support column 12 by welding. A top plate 14 is fixedly welded between multiple first connecting blocks 13 to form a stable top support structure. An electric push rod 15 is detachably connected to the upper end of the top plate 14 by bolts. The output end of the electric push rod 15 passes through the top plate 14 and is fixedly connected to a second connecting block 16 by welding. A connecting plate 17 is detachably connected to the lower end of the second connecting block 16 by bolts. The electric push rod 15 can drive the second connecting block 16 and the connecting plate 17 to move vertically. Two fixing boxes 18 are symmetrically fixed to the lower end of the connecting plate 17. Two springs 19 are detachably connected inside the fixing boxes 18. The end of the spring 19 away from the inner top wall of the fixing box 18 abuts against a limit plate 20. A connecting column 21 is fixedly connected to the lower end of the limit plate 20. A detection plate 22 is fixedly connected to the lower end of the connecting column 21 by screws. Multiple detection contacts 23 are detachably connected to the lower end of the detection plate 22. The silicone button 11 on the surface of the remote control body 10 can be pressed by the detection contacts 23.
[0021] It should be noted that this utility model is a TV remote control button testing device. In use, the remote control body 10 is first placed on the designated position on the surface of the base 1. The servo motor 2 is then started. The servo motor 2 drives the rotating rod 3 and the first bevel gear 4 to rotate. The first bevel gear 4, through meshing with the second bevel gears 5 on both sides, drives the two threaded rods 6 to rotate synchronously. When the threaded rods 6 rotate, the moving block 7 moves along the axis of the threaded rod 6 under the limiting action of the guide groove, thereby driving the connecting clamp 8 and the anti-slip plate 9 to move closer to the remote control body 10 until the anti-slip plates 9 on both sides are tightly pressed against the side walls of the remote control body 10, completing the clamping and fixing of the remote control body 10. Then, the electric push rod 15 is started. The output end of the electric push rod 15 extends downward, driving the second connecting block 16, connecting plate 17, fixing box 18, detection plate 22 and detection contact 23 to move downward synchronously. When the detection contact 23 contacts the silicone button 11, the electric push rod 15 continues to push. At this time, the spring 19 undergoes elastic deformation under the compression of the limiting plate 20. Through the elasticity buffer of the spring 19, the detection contact 23 presses the silicone button 11 with stable pressure, realizing the pressing test of the silicone button 11. After the test is completed, the output end of the electric push rod 15 retracts upward, driving the detection component to reset. At the same time, the servo motor 2 rotates in the opposite direction, causing the connecting clamp 8 and anti-slip plate 9 to move away from the remote control body 10, so that the remote control body 10 that has completed the test can be taken out.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
