Description

Technical Field

[0001] This utility model relates to the technical field of button life testing equipment, and in particular to an underwater button life testing machine. Background Technology

[0002] With the development of electronic products, wearable products (wristbands, watches), sports appliances (bicycle speedometers, action cameras), mobile phones, tablets and other electronic devices all need to have high waterproof performance. These electronic products need to be equipped with at least one physical button for operation. Therefore, the button needs to undergo a life test to simulate the life of operation in water using an underwater button life tester.

[0003] Existing underwater button life testing machines require the user to submerge their hands underwater to retrieve the test object after the test. To enrich the test data, additives are often added to the water to simulate different water environments. Some test environments are corrosive, and prolonged immersion in such liquids can damage the skin, necessitating the wearing of gloves. However, wearing gloves makes operation difficult, requiring the liquid to be drained before retrieving the test object, resulting in wasted test media, high testing costs, and low efficiency. Furthermore, while existing underwater button life testing machines can simulate pressure environments at different water depths through pressurization, the water depth into which electronic products are immersed often varies in actual use. Therefore, testing requires continuous pressurization and depressurization to simulate different water depths. Repeated pressurization and depressurization increase energy consumption and testing costs, and the slow pressure response makes it difficult to meet the demands of rapidly changing pressure environments.

[0004] On the other hand, the pressure applied to the buttons in the existing underwater button life tester is preset and adjusted before the test begins. However, when the test environment pressure changes, the corresponding pressing pressure on the buttons will also change, resulting in the pressing pressure not being able to remain constant. It can only be preset and adjusted according to the preset relationship between the environmental pressure and the pressing pressure, and cannot be adjusted in real time according to the actual pressing pressure, which leads to a decrease in the reliability of the test results. Therefore, it is necessary to improve it. Utility Model Content

[0036] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0037] An underwater button life testing machine, such as Figures 1 to 7As shown, the device includes a pressure vessel 1, a test chamber 111 inside the pressure vessel 1, and a test device 2 inside the test chamber 111. The test device 2 includes a loading drive mechanism, a loading lifting frame, and a test mechanism. The loading lifting frame is slidably installed inside the test chamber 111, and the test mechanism is fixedly installed on the loading lifting frame. The loading drive mechanism is connected to the loading lifting frame in a transmission manner. The test mechanism includes a fine-tuning lifting seat 23, a fine-tuning drive assembly, at least one test fixture 25, at least one pressing test assembly 261, and at least one workpiece fixture 27. The fine-tuning lifting seat 23 is slidably installed on the loading lifting frame, the test fixture 25 is fixedly installed on the fine-tuning lifting seat 23, the pressing test assembly 261 is movably installed on the test fixture 25, and the workpiece fixture 27 is fixedly installed on the loading lifting frame and located below the pressing test assembly 261. Traditional underwater button life testing machines require the user to submerge their hand in the test liquid when loading and unloading the object, which is inconvenient. Furthermore, during testing, the object can only maintain a fixed height, and depth variation testing can only be performed by increasing or decreasing the pressure inside pressure vessel 1, resulting in a slow pressure change response. In contrast, this invention... Figure 2 As shown, the loading lifting frame is raised and lowered by the loading drive mechanism, so that the testing mechanism automatically floats out of the liquid surface when loading and unloading the test object, which is convenient to operate, eliminates the need to drain the liquid, improves testing efficiency and reduces testing costs. Furthermore, during the testing process, the test object can be raised and lowered to simulate small changes in water depth, which has a faster response speed and more accurate test results than traditional pressure change simulations. The height of the fine-tuning lifting seat 23 can be adjusted by the fine-tuning drive component to adjust the initial distance between the pressing test component 261 and the workpiece clamp 27, thereby enabling testing of test objects of different sizes and expanding the testing range.

[0038] Specifically, such as Figure 5 As shown, the testing device 2 is also equipped with a pressure regulating mechanism, which includes a pressure sensor 28 and a pressure regulating component 262. The pressure sensor 28 and the pressure regulating component 262 are respectively fixedly installed on the loading lifting frame. The pressure regulating component 262 is triggered and cooperates with the pressure sensor 28. Both the pressing test component 261 and the pressure regulating component 262 use pen-shaped cylinders and are connected to the same air source 5 through the same air path. Real-time pressure regulation is performed through the pressure regulating mechanism. Since the pressing test component 261 and the pressure regulating component 262 are driven by the same air source 5, the pressing force of both remains the same. When the pressing test component 261 presses the button, the pressure regulating component 262 presses the pressure sensor 28, thereby measuring the force of each press and adjusting the pressing force in real time to ensure that the pressing force remains constant and improve the reliability of the test results. Both the pressing test component 261 and the pressure regulating component 262 use pen-shaped cylinders of the same specification, and a rubber sleeve is installed on the piston rod of the pen-shaped cylinder to avoid hard contact.

[0039] Specifically, such as Figure 3 As shown, a filter plate 14 is provided at the bottom of the test chamber 111. The filter plate 14 has multiple filter holes, and a mounting base plate 15 is fixedly installed on the filter plate 14. The loading drive mechanism includes two loading drive cylinders 211, two loading guide plates 212, and two loading guide rods 213. The two loading drive cylinders 211 are fixedly installed on the mounting base plate 15 at intervals. The two loading guide plates 212 are fixedly installed on the upper part of the two loading drive cylinders 211. The piston rods of the two loading drive cylinders 211 are connected to the left and right sides of the loading lifting frame, respectively. The upper ends of the two loading guide rods 213 are fixedly installed on the left and right sides of the loading lifting frame, respectively. The two loading guide rods 213 are slidably connected to the two loading guide plates 212. When loading and unloading the test object, it is inevitable that the test object, other parts, or external impurities will fall. The filter plate 14 blocks these impurities to prevent clogging of the pipeline. At the same time, the filter plate 14 also has the function of supporting the installation and is used to install the test device 2. The loading lifting frame is driven to rise and fall synchronously by two loading drive cylinders 211. The loading drive cylinders 211 not only serve as the driving source but also as the fixed frame, eliminating the need for an additional frame structure. The structure is simple and low in cost. The loading guide plate 212 and the loading guide rod 213 provide guidance, improving the stability during lifting.

[0040] Specifically, such as Figure 4 and Figure 5As shown, the loading lifting frame includes a loading base plate 221, a loading top plate 222, two connecting vertical plates 223, two cylinder push plates 224, and at least two fine-tuning guide rods 225. The lower ends of the two connecting vertical plates 223 are fixedly connected to the left and right ends of the loading base plate 221, respectively. The two cylinder push plates 224 are fixedly installed on the upper ends of the two connecting vertical plates 223, respectively. The piston rods of the two loading drive cylinders 211 are fixedly connected to the two cylinder push plates 224, respectively. The upper ends of the two loading guide rods 213 are fixedly connected to the two cylinder push plates 224, respectively. The lower ends of each fine-tuning guide rod 225 are fixedly connected to the upper surface of the loading base plate 221. The upper end is fixedly connected to the lower end face of the loading top plate 222, and the workpiece clamp 27 is fixedly installed on the loading base plate 221. The loading lifting frame is assembled from plates, and a U-shaped test space is formed between the two connecting vertical plates 223 and the loading base plate 221. The test device 2 is set in this test space for testing to reduce the vertical installation height and reduce the overall size of the machine. The workpiece clamp 27 is fixedly installed on the loading base plate 221 to keep the workpiece clamp 27 relatively fixed, while the pressing test component 261 is fixed on the fine-tuning lifting seat 23 through the test clamp 25. The fine-tuning lifting seat 23 can move relative to the workpiece clamp 27 to adapt to test objects of different sizes. The structure is simple and the cost is low. Two fine-tuning guide rods 225 are used to slide the fine-tuning lifting seat 23. Preferably, four fine-tuning guide rods 225 are provided to improve the stability of the fine-tuning lifting seat 23 when it is raised and lowered.

[0041] The fine-tuning drive assembly includes a fine-tuning nut 244, a fine-tuning screw 241, a fine-tuning handwheel 242, and a locking buckle 243. The fine-tuning nut 244 is fixedly installed on the fine-tuning lifting seat 23, the fine-tuning screw 241 is rotatably installed on the loading top plate 222, the fine-tuning handwheel 242 is fixedly installed on the upper end of the fine-tuning screw 241, the fine-tuning screw 241 is threadedly connected to the fine-tuning nut 244, and the locking buckle 243 is fixedly installed on the loading top plate 222 and locks against the fine-tuning screw 241.

[0042] The loading top plate 222 is used to install the fine-tuning screw 241 and limit the fine-tuning lifting seat 23. Before testing, the fine-tuning screw 241 is rotated by rotating the fine-tuning handwheel 242 to drive the fine-tuning lifting seat 23 to rise and fall. Since it only needs to be adjusted when switching between different sizes of test objects, there is no need to set up an electric adjustment mechanism. The screw structure is used for manual adjustment, which is convenient for small-distance fine-tuning. The structure is simple and the cost is low. During adjustment, the loading drive mechanism raises the test mechanism to facilitate adjustment.

[0043] Multiple buffer pads 16 are provided on the lower part of the loading base plate 221 or the upper part of the mounting base plate 15. The buffer pads 16 cushion the loading base plate 221 to prevent it from impacting the mounting base plate 15 during descent, thereby improving reliability and stability.

[0044] Specifically, such as Figure 6 As shown, the test fixture 25 includes two test frames 251 arranged symmetrically on the left and right. The test frames 251 are fixedly installed on the fine-tuning lifting seat 23. Each test frame 251 has an arc-shaped slide groove 252. An angle adjustment component is slidably installed in each slide groove 252. The angle adjustment component includes an angle adjustment slider 253, an angle adjustment nut 254 and a locking screw 255. The angle adjustment slider 253 and the angle adjustment nut 254 are respectively set on the front and rear sides of the test frame 251. The locking screw 255 passes through the angle adjustment slider 253 and the slide groove 252 in sequence and is threadedly connected to the angle adjustment nut 254. Each angle adjustment slider 253 is provided with a pressing test component 261.

[0045] Two test racks 251 each mount at least one press test component 261. Of course, depending on the button layout of the object under test, the number of press test components 261 can be increased as needed, allowing all buttons to be tested simultaneously in one operation, thus improving testing efficiency. An angle adjustment component is slidably mounted on an arc-shaped groove 252. By adjusting the position of the angle adjustment component on the groove 252, the angle and position of the press test component 261 can be adjusted, allowing simultaneous testing of buttons on two adjacent sides of the object under test, and enabling testing of button lifespan at different press angles, enriching the test results. When adjusting the angle, the angle adjustment component is moved by rotating the loosening screw 255. After adjusting to the desired position, the locking screw 255 is tightened to bring the angle adjustment slider 253 and the angle adjustment nut 254 close to the clamping test rack 251 to complete the locking. The structure is simple, low-cost, and easy to operate.

[0046] Specifically, the fine-tuning lifting seat 23 is provided with multiple test fixtures 25 in the horizontal direction, and two adjacent test fixtures 25 are staggered in the vertical direction. The corresponding loading lifting frame is provided with multiple workpiece fixtures 27, each corresponding to a test fixture 25. By using multiple test fixtures 25 arranged in a vertically staggered manner, multiple objects to be tested can be tested simultaneously, further improving testing efficiency and reducing the horizontal space occupied.

[0047] Specifically, such as Figure 7As shown, the workpiece fixture 27 includes a fixture base plate 271, a fixture side plate 272, a fixed clamping plate 273, a movable clamping plate 274, an adjusting screw 275, and at least one adjusting guide rod 276. The fixture base plate 271 is fixedly installed on the loading lifting frame, the fixed clamping plate 273 is fixedly installed on the rear side of the fixture base plate 271, the fixture side plate 272 is fixedly installed on the front side of the fixture base plate 271, and the movable clamping plate 274 is slidably installed on the fixed clamping plate 273 and the fixture side plate 274. Between points 2 and 3, the front part of the adjusting screw 275 is threadedly connected to the side plate 272 of the fixture, and the rear end of the adjusting screw 275 is rotatably connected to the movable clamping plate 274. The rear end of the adjusting guide rod 276 is fixedly installed on the movable clamping plate 274, and the front part of the adjusting guide rod 276 is slidably connected to the side plate 272 of the fixture. A pad 277 is provided on the upper end surface of the fixture base plate 271, and side pads 278 are respectively provided on the front side of the fixed clamping plate 273 and the rear side of the movable clamping plate 274. When clamping the object to be measured, by loosening the adjusting screw 275, the movable clamping plate 274 is driven to move away from the fixed clamping plate 273, and the object to be measured is placed between the movable clamping plate 274 and the fixed clamping plate 273. Then, the adjusting screw 275 is tightened to drive the movable clamping plate 274 to move towards the fixed clamping plate 273, thereby clamping and fixing the object to be measured. The structure is simple and the operation is convenient. The movable clamping plate 274 is guided by the adjustable guide rod 276 to reduce its wobbling and ensure that it is relatively parallel to the fixed clamping plate 273. Preferably, two adjustable guide rods 276 are provided to increase movement stability. The object to be tested is contacted by the pad 277 and the side pad 278. The pad 277 and the side pad 278 are made of PU material or Teflon tape to avoid damaging the object to be tested.

[0048] Specifically, the pressure vessel 1 includes a tank body 11, a tank cover 12, and multiple locking components 13. One side of the tank cover 12 is hinged to one side of the tank body 11. The lower ends of each locking component 13 are spaced along the upper edge of the tank body 11 in the circumferential direction. Each locking component 13 includes a locking screw 131 and a locking nut 132. The lower end of the locking screw 131 is hinged to the tank body 11, and the locking nut 132 is threaded to the locking screw 131. The locking nut 132 abuts against the tank cover 12, and a lifting ring 133 is provided on the upper part of the locking nut 132. The underwater button life testing machine is also provided with a base 3. The tank body 11 is fixedly installed on the base 3. An opening cylinder 4 is provided on each side of the pressure vessel 1. The lower end of the opening cylinder 4 is hinged to the base 3, and the piston rod of the opening cylinder 4 is hinged to one side of the tank cover 12.

[0049] Traditional underwater button life testing machines require manual opening of the can lid 12 when loading and unloading the test object. However, the can lid 12 is often quite heavy to ensure its pressure-bearing capacity, making manual operation time-consuming and labor-intensive. This invention, however, automatically opens the can lid 12 using an opening cylinder 4, eliminating the need for manual operation, thus improving work efficiency and saving time and effort. To open the can lid 12, first loosen or remove each locking nut 132, then rotate the locking screw 131 downwards to unlock the can lid 12, and then activate the opening cylinder 4 to automatically open the can lid 12. To close the can lid 12, first activate the opening cylinder 4 to automatically close the can lid 12, then rotate each locking screw 131 upwards and tighten the locking nuts 132, causing the locking nuts 132 to press against the can lid 12, completing the locking process. To ensure a tight seal, a sealing ring is provided between the can lid 12 and the can body 11; to prevent the locking nut 132 from loosening due to unauthorized rotation, a washer is provided between the locking nut 132 and the can lid 12. By providing a lifting ring 133 on the locking nut 132, there is no need to provide a separate lifting ring 133, resulting in a simple structure and low cost. Furthermore, the lifting ring 133 can also act as a handle, making it easy to rotate the locking nut 132 by hand without the need for tools, thus making operation more convenient.

[0050] Specifically, a heating chamber 112 is provided at the lower part of the tank body 11. The heating chamber 112 is located below and communicates with the test chamber 111. A heating mechanism 18 is provided inside the heating chamber 112, and a drain pipe 171 is connected to the lower part of the heating chamber 112. A solenoid valve 172 is installed on the drain pipe 171. The test liquid in the heating chamber 112 is heated by the heating mechanism 18, and the heat is gradually conducted to the test chamber 111, thereby heating the test liquid as a whole to simulate different test environment temperatures. The lower placement of the heating mechanism 18 can prevent dry burning when the test liquid level is low, thus improving safety. After the test is completed, the test liquid is discharged from the drain pipe 171 by opening the solenoid valve 172, improving the convenience of operation and automatic drainage, eliminating the need for manual valve opening.

[0051] Specifically, at least one glass observation window 113 is provided on the side wall of the tank 11, and a lighting device is also provided inside the test chamber 111, which is fixedly installed on the inner side wall of the tank 11. The test situation can be observed in real time through the glass observation window 113, and supplementary lighting is provided by the lighting device to improve clarity.
