Description

Technical Field

[0001] The present invention belongs to the technical field of silicone button testing devices, and particularly relates to a testing device for an integrated silicone type hidden aperture audio button. Background Art

[0002] Smart speakers have become one of the representatives of the new generation of speakers. They are capable of communicating with wireless devices and users. Therefore, the speaker needs to have a certain number of buttons for convenient control. Currently, the buttons on the market for speakers are roughly divided into plastic buttons and silicone buttons. Among them, compared with plastic buttons, silicone buttons have a small sound, a relatively soft texture, good resilience, and do not resonate with the speaker when pressed, thus not affecting the sound quality of the speaker. In addition, there is basically no gap between the silicone button and the housing, thereby preventing dust from entering the speaker. Therefore, silicone buttons are more popular.

[0003] When the existing silicone buttons are produced, in order to ensure the quality of the silicone buttons, generally, high and low temperature tests, scratch tests, and boiling water tests are required for the silicone buttons. Among them, when performing a scratch test on the silicone button, since the existing scratch test device has only one test head and the landing point of the test head is fixed, this results in an inability to perform a more balanced scratch test on the entire surface of the silicone button. In addition, since the top of the silicone button is arc-shaped, when the silicone button is not placed correctly, the silicone button is prone to deviation, resulting in the test head being unable to accurately perform a scratch test on the silicone button.

[0004] Therefore, it is very necessary to invent a testing device for an integrated silicone type hidden aperture audio button to solve the above problems. Summary of the Invention

[0015] The technical effects and advantages of the present invention:

[0016] 1. When detecting the silicone button, multiple first pressure rods can cooperate with the second pressure rod to cover a diameter of the silicone button. Therefore, when testing the silicone button once, the simultaneous detection of multiple points on the top of the silicone button can be completed. In addition, after the test bench completes one-side detection, the V-shaped protrusion can cooperate with the lever to make the turntable drive the silicone button to automatically rotate a certain angle. Thus, when the test bench rotates one week, the comprehensive detection of the top of the silicone button can be completed, making the test on the surface of the silicone button more uniform.

[0017] 2. After the first pressing test is completed, as the electric telescopic rod gradually returns to its original position, at this time, the test bench starts to rotate automatically under the cooperation of the lever and the V-shaped protrusion. During this process, the pressure pipe can press the silicone button under the action of the second spring and rotate with it, so as to ensure that the position of the silicone button will not move randomly during the rotation of the test bench, and further ensure the smooth progress of the subsequent test.

[0018] 3. When the threaded tube pushes the second arc-shaped plate upward, the second arc-shaped plate can pull multiple first pressing rods upward through rollers. At the same time, the second pressing rod is also gradually pulled upward by the L-shaped rod, so that the arc length enclosed by the bottoms of the multiple first pressing rods and the second pressing rod gradually increases, thus meeting the test requirements for silicone buttons with a larger diameter. Similarly, when the threaded tube pulls the second arc-shaped plate downward, the bottoms of the multiple first pressing rods can approach each other, so that the arc length enclosed by the bottoms of the multiple first pressing rods and the second pressing rod gradually shortens, thereby meeting the test requirements for silicone buttons with a smaller diameter.

Detailed implementation manner

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides as Figures 1-8A test device for an integrated silicone - type hidden - aperture sound button, as shown, includes a base 1. A frustum 2 is fixedly connected to the top of the base 1. A test bench 3 is movably sleeved on the top of the frustum 2. A positioning rod 4 is fixedly connected to the center of the inner top of the test bench 3. The bottom of the positioning rod 4 is movably inserted into the top of the frustum 2. A plurality of adjusting devices 5 are arranged between the inner wall of the test bench 3 and the frustum 2. The adjusting device 5 includes a V - shaped protrusion 51. The V - shaped protrusion 51 is fixedly connected to the side wall of the frustum 2, and the plurality of V - shaped protrusions 51 are rotationally symmetric about the center of the frustum 2. The opening of the V - shaped protrusion 51 faces upward. The V - shaped protrusion 51 includes a vertical side 511 and an inclined side 512. The vertical side 511 of the V - shaped protrusion 51 is perpendicular to the base 1, and the top of the vertical side 511 of the V - shaped protrusion 51 is lower than the top of the inclined side 512. The top ends of adjacent inclined sides 512 are flush with the inner side of the vertical side 511. A straight rod 52 is arranged on the side of the V - shaped protrusion 51 away from the frustum 2. The straight rod 52 is perpendicularly and fixedly connected to the inner wall of the test bench 3. A lever 53 is arranged at the bottom of the straight rod 52. The lever 53 is hinged to the inner wall of the test bench 3 through a torsion spring. The lever 53 is parallel to the straight rod 52 in the natural state, and the lever 53 can only deflect upward. The height of the lever 53 in the natural state is higher than the height of the inclined side 512 of the V - shaped protrusion 51, and the vertical distance between the lever 53 and the straight rod 52 is greater than the thickness of the inclined side 512 of the V - shaped protrusion 51. The diameter of the lever 53 is smaller than the distance between the adjacent inclined side 512 and the vertical side 511. A magnetic ring 6 is rotatably connected to the bottom of the test bench 3. A plurality of telescopic rods 7 are fixedly connected between the bottom of the magnetic ring 6 and the top of the base 1, and a first spring 8 is sleeved on the telescopic rod 7. A test device 9 is arranged on the top of the test bench 3;

[0032] After the silicone button is placed on the top of the test bench 3, start the test device 9 to gradually approach the top of the silicone button. When the test device 9 contacts the silicone button, the test bench 3 can move downward under the extrusion of the test device 9 and compress the telescopic rod 7 and the first spring 8. During this process, the test bench 3 drives the straight rod 52 and the lever 53 to move along the inner side of the vertical edge 511 of the V-shaped protrusion 51. When the lever 53 contacts the inclined edge 512 of the V-shaped protrusion 51, the lever 53 starts to deflect upward due to the block of the inclined edge 512. As the lever 53 continues to move downward, when the straight rod 52 contacts the inclined edge 512 of the V-shaped protrusion 51, the lever 53 and the inclined edge 512 of the V-shaped protrusion 51 are staggered, so that the lever 53 can return to its original position under the action of the torsion spring. At this time, the test bench 3 stops moving, and the test device 9 also completes the first test. At this time, the lever 53 is located outside the V-shaped protrusion 51. As the test device 9 gradually returns to its original position, the test bench 3 can drive the lever 53 and the straight rod 52 to move upward gradually under the action of the first spring 8. When the lever 53 contacts the bottom of the inclined edge 512, the pressure of the inclined edge 512 on the lever 53 causes the lever 53 to drive the test bench 3 to start rotating. When the lever 53 separates from the inclined edge 512 of the V-shaped protrusion 51 again, the bottom of the lever 53 just moves to the top of the adjacent V-shaped protrusion 51, and the test bench 3 drives the silicone button to complete a certain angle of rotation. And when the test bench 3 stops rotating, the test bench 3 can remain stationary under the suction of the magnetic ring 6. When the test device 9 tests the silicone button again, the test point of the test device 9 on the silicone button changes, so as to achieve the purpose of uniformly testing the surface of the silicone button without manually adjusting the position of the silicone button.

[0033] Such as Figures 1-4As shown, the test device 9 includes a U-shaped plate 90, which is fixedly connected to the top of the base 1. Inside the U-shaped plate 90, there is a first arc-shaped plate 91. Along the direction of the diameter of the first arc-shaped plate 91, a plurality of first pressing rods 92 are slidably inserted through the top of the first arc-shaped plate 91, and the plurality of first pressing rods 92 are symmetric about the center line of the arc-shaped plate. At the center of the top of the first arc-shaped plate 91, a threaded tube 93 is fixedly connected. An electric telescopic rod 94 is inserted into the threaded tube 93. The bottom of the electric telescopic rod 94 is fixedly connected to the top of the first arc-shaped plate 91, and the top of the electric telescopic rod 94 is fixedly connected to the inner top of the U-shaped plate 90. The threaded tube 93 is successively sleeved with a second arc-shaped plate 95 and a threaded sleeve 96 from top to bottom. The second arc-shaped plate 95 is slidably sleeved with the threaded tube 93, and the threaded sleeve 96 is screwed together with the threaded tube 93 by threads. A connecting ring 97 is provided between the threaded sleeve 96 and the second arc-shaped plate 95. The top of the connecting ring 97 is fixedly connected to the bottom of the second arc-shaped plate 95, and the bottom of the connecting ring 97 is rotatably connected to the top of the threaded sleeve 96. A chute is opened at the bottom of the second arc-shaped plate 95, and the top of the first pressing rod 92 is slidably clamped in the chute. The bottom center of the first arc-shaped plate 91 is slidably inserted with a second pressing rod 98, and the top of the second pressing rod 98 is also slidably inserted into the bottom of the electric telescopic rod 94. L-shaped rods 99 are fixedly connected to the front and rear sides of the second pressing rod 98, and the tops of the two L-shaped rods 99 are respectively fixedly connected to the front and rear sides of the connecting ring 97. A roller 10 is fixedly sleeved on the part of the first pressing rod 92 located inside the chute, and balls 11 are installed at the bottoms of the first pressing rod 92 and the second pressing rod 98. The length of the first pressing rod 92 matches the length of the threaded tube 93, and the bottom of the first pressing rod 92 can always be on the edge of the same circle as the bottom of the second pressing rod 98;

[0034] When it is necessary to test the silicone button, first turn the threaded sleeve 96 according to the diameter of the silicone button, so that the second arc-shaped plate 95 can move up and down along the direction of the threaded tube 93 driven by the threaded sleeve 96. During this process, when the threaded tube 93 pushes the second arc-shaped plate 95 upward, the second arc-shaped plate 95 can pull a plurality of first pressing rods 92 upward through the roller 10. At the same time, the second pressing rod 98 also gradually moves upward under the pull of the L-shaped rod 99, so that the arc length formed by the bottoms of the plurality of first pressing rods 92 and the second pressing rod 98 gradually increases, so as to meet the test requirements of silicone buttons with a larger diameter. Similarly, when the threaded tube 93 pulls the second arc-shaped plate 95 downward, the bottoms of the plurality of first pressing rods 92 can approach each other, so that the arc length formed by the bottoms of the plurality of first pressing rods 92 and the second pressing rod 98 gradually shortens, and thus the test requirements of silicone buttons with a smaller diameter can be met;

[0035] In addition, since multiple first pressing rods 92 can cooperate with the second pressing rod 98 to cover a diameter of the silicone button, when testing the silicone button once, the simultaneous detection of multiple points on the top of the silicone button can be completed. In addition, since the test bench 3 will drive the silicone button to automatically rotate a certain angle after one side of the detection is completed, when the test bench 3 rotates one week, the comprehensive detection of the top of the silicone button can be completed, thereby making the test on the surface of the silicone button more uniform.

[0036] As Figures 2-4 shown, a movable sleeve 12 is slidably sleeved at a position near the bottom end of the second pressing rod 98. Through holes are vertically formed at positions of the movable sleeve 12 opposite to two L-shaped rods 99, and the L-shaped rods 99 are inserted through the through holes. A limiting rod 13 is slidably inserted through a part of the L-shaped rod 99 located in the through hole in the vertical direction. Two ends of the limiting rod 13 are respectively fixedly connected to the top and bottom hole walls of the through hole, and a second spring 14 is sleeved on a part of the limiting rod 13 located at the bottom of the L-shaped rod 99. The bottom of the movable sleeve 12 is rotatably connected to a funnel-shaped pressing tube 15. The distance from the bottom of the second pressing rod 98 to the bottom of the pressing tube 15 is less than the maximum expansion and contraction amount of the second spring 14;

[0037] During the process of testing the silicone button, as the electric telescopic rod 94 extends, the first arc-shaped plate 91 drives multiple first pressing rods 92, the second pressing rod 98, and the pressing tube 15 to gradually approach the silicone button. When the pressing tube 15 contacts the top of the silicone button, the pressing tube 15 starts to push the movable sleeve 12 upward and compress the second spring 14 due to the extrusion of the silicone button. As the electric telescopic rod 94 continues to extend, the pressing tube 15 continues to move upward. When the bottom of the second pressing rod 98 contacts the top of the silicone button, the pressing tube 15 stops moving. At this time, the pressing tube 15 presses the silicone button tightly under the reaction force of the second spring 14;

[0038] When the first pressing test is completed, as the electric telescopic rod 94 gradually returns to its original position, at this time, the test bench 3 starts to rotate automatically under the cooperation of the toggle rod 53 and the V-shaped protrusion 51. During this process, the pressing tube 15 can press the silicone button tightly under the action of the second spring 14 and rotate with it, so as to ensure that the position of the silicone button will not move randomly during the rotation of the test bench 3, thereby ensuring the smooth progress of subsequent tests.

[0039] As Figure 5 and Figure 6As shown in the figure, a circular plate 16 is provided on the top of the test bench 3. A plurality of insertion rods 17 are fixedly connected to the bottom of the circular plate 16. The insertion rods 17 are slidably inserted into the top of the test bench 3, and a third spring 18 is connected between the bottom of the insertion rod 17 and the test bench 3. A limiting column 19 is slidably inserted through the top of the circular plate 16. The bottom of the limiting column 19 is slidably inserted into the top of the test bench 3, and a fourth spring 20 is connected between the bottom of the limiting column 19 and the test bench 3. The top of the limiting column 19 is flush with the top of the circular plate 16, and the maximum expansion and contraction amount of the limiting column 19 is equal to the distance from the bottom of the circular plate 16 to the top of the test bench 3;

[0040] When the silicone key is placed on the top of the circular plate 16, since the top of the limiting column 19 is flush with the top of the circular plate 16, at this time, the silicone key can slide freely along the top of the circular plate 16, so as to facilitate the free adjustment of the position of the silicone key. After the position of the silicone key is adjusted, with the extrusion of the first pressing rod 92 and the second pressing rod 98 on the silicone key, at this time, the circular plate 16 can compress the third spring 18 and move downward. During this process, as the circular plate 16 moves downward, the limiting column 19 opposite to the silicone key can move downward under the extrusion of the silicone key and compress the fourth spring 20, while the limiting column 19 that is not in contact with the silicone key can block around the silicone key under the action of the fourth spring 20, so as to fix the silicone key with the adjusted position, and further ensure that the position of the silicone key will not move during the subsequent side view process.
