[0036] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features.

[0037] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0038] In order to solve the technical problems of test error and low efficiency caused by inaccurate positioning or inaccurate alignment when the hole position of the waterproof and breathable film of the watch or bracelet is tested by pressure test or water test in the prior art, embodiments of the present application provide a test device.

[0039] The specific structure of the test device provided by the embodiments of the present application will be described in detail below. According to the drawings shown, the specific structure of the test device includes a workbench 1, a positioning jig 2, and a water testing mechanism 3.

[0040] The positioning jig 2 is fixedly arranged on the workbench 1. The positioning jig 2 can ensure accurate positioning of the product to be tested during the test process, so as to avoid inaccurate testing of the product to be tested due to position deviation of the product to be tested. In addition, the positioning jig 2 can be assembled with the same or different products to be tested for multiple times, thereby improving the utilization rate of resources.

[0041] The positioning jig 2 is detachably arranged with the product to be tested. Specifically, the positioning jig 2 can be customized according to the type and size of different products to be tested, so as to adapt to the processing needs of different products to be tested, thereby improving the flexibility and multifunctionality of testing different products to be tested.

[0042] It should be noted that the positioning jig 2 of the embodiments of the present application can be provided in multiple numbers, for example, two positioning jigs 2 are provided, and both of the two positioning jigs 2 are arranged on the workbench 1. In this way, two products to be tested can be tested at the same time, thereby improving the production efficiency and yield of products.

[0043] It should be further noted that the product to be tested of the embodiments of the present application is a wearable device such as a watch or a bracelet, and a waterproof and breathable film arranged on the wearable device.

[0044] The water testing mechanism 3 includes a water injection assembly 31, a first driver 32, and a moving seat 33. The first driver 32 is arranged on the workbench 1, and the power output shaft of the first driver 32 is drivingly connected with the moving seat 33, so as to push the moving seat 33 to move in the direction of the product to be tested. The water injection assembly 31 is arranged on the moving seat 33, and the injection direction of the water injection assembly 31 is towards the product to be tested.

[0045] Specifically, in order to achieve precise alignment during the water injection process of the product under test and prevent mis-testing due to misalignment with the holes of the waterproof and breathable membrane, the power output shaft of the first driver 32 is used to drive the moving seat 33 to move along the direction of the product under test assembled in the positioning fixture 2. The moving seat 33 drives the water injection component 31 to approach or come into contact with the product under test, so that the product under test is less likely to shake. Thus, during the waterproof test of the product under test, the water injection component 31 is precisely aligned with the product under test, avoiding mis-testing due to misalignment with the holes of the waterproof and breathable membrane, ensuring the correct water injection direction, and allowing direct pressure testing or full water injection of the waterproof and breathable membrane. Since the water injection component 31 is located inside the movable base 33, when the movable base 33 moves to the position fixture 2, the water inlet pipe will transport some water from the water storage tank 12 to the water injector. Then, according to the preset water injection volume and water injection speed, the water injector is controlled to inject water into the product under test. This setting ensures that the watch will not be subjected to excessive pressure or impact during the water injection process.

[0046] It should be noted that the water injector is equipped with sensors that can monitor and acquire various parameters during the water injection process in real time, such as water velocity, flow rate, and pressure. The sensors then transmit the detected parameter data to the control system in real time. These sensors can be pressure sensors, flow sensors, etc., and the specific type is not limited here.

[0047] The first driver 32 can be understood as a cylinder, that is, the power output shaft of the cylinder is used to drive the moving seat 33 to move.

[0048] In some specific embodiments, the positioning fixture 2 is hollow and has an assembly cavity 21 for assembling the product to be tested; a through opening 22 is provided in the cavity wall of the assembly cavity 21 for the movable seat 33 to extend into the assembly cavity 21 and abut against the product to be tested.

[0049] Specifically, since the waterproof and breathable membrane of the product under test is located on the side of the product under test, in order to direct the water injection direction of the water injection component 31 toward the waterproof and breathable membrane, a through-hole 22 is provided in the side wall of the assembly cavity 21 facing the first water injection component 31. The through-hole 22 is open to the outside so that the side of the product under test assembled in the assembly cavity 21 is exposed. The power output shaft of the first driver 32 pushes the moving seat 33 through the through-hole 22 into the assembly cavity 21 until the moving seat 33 moves so that the water injection component 31 can approach or abut against the product under test, thereby achieving a precise water injection test on the waterproof and breathable membrane located on the side of the product under test.

[0050] In a further embodiment, an avoidance groove 23 is provided on the outer side wall of the fixture, and the avoidance groove 23 is connected to the through opening 22.

[0051] Specifically, in order to prevent the water injection component 31 from being unable to approach the product under test due to the collision between the movable seat 33 and the positioning fixture 2 when the first driver 32 pushes the movable seat 33 to move in the direction of the product under test, a clearance groove 23 for accommodating the movable seat 33 is provided on the outer wall of the fixture. That is, after the water injection component 31 passes through the clearance groove 23 and the through opening 22, it can approach the product under test. At this time, the movable seat 33 is located in the clearance groove 23 and the wall of the clearance groove 23 is a certain distance away, which effectively prevents the movable seat 33 from colliding with the positioning fixture 2 and ensures that the water injection component 31 can accurately and smoothly approach the product under test.

[0052] In some specific embodiments, the testing apparatus also includes a pressing component 4 for pressing the product under test, the pressing component 4 being disposed on the worktable 1.

[0053] Specifically, since even slight deviations can cause misalignment of the water contact surface, thus affecting the accuracy of the test results, applying a certain pressure to the product under test assembled in the positioning fixture 2 by pressing component 4 ensures that the product under test fits tightly against the cavity wall of the assembly cavity 21. This effectively prevents slight displacement of the product under test in the positioning fixture 2, ensuring correct alignment and pressure distribution of the product under test before and during water injection, thereby improving the accuracy of the test results.

[0054] Specifically, the pressing assembly 4 includes a second driver 41 and a pressing part 42; the power output shaft of the second driver 41 is driven to the pressing part 42, which can push the pressing part 42 to move in the vertical direction.

[0055] Specifically, before the water injection component 31 injects water into the product under test, the power output shaft of the second driver 41 pushes the entire pressing part 42 downward and moves until the bottom surface of the pressing part 42 can abut against the top surface of the product under test and apply a certain pressing force to the product under test to push the product under test to fit tightly against the bottom cavity wall of the assembly cavity 21, so that the product under test can be stably fixed in the assembly cavity 21 and it is difficult for it to move or shake during subsequent testing.

[0056] More specifically, the pressing part 42 includes a lifting seat 421 and a plurality of pressing posts 422. The power output shaft of the second driver 41 is drivenly connected to the lifting seat 421. Each pressing post 422 is disposed on the lifting seat 421, and the bottom surface of each pressing post 422 is formed with a pressing surface 423 for contacting the surface of the product to be tested.

[0057] Specifically, since each pressing column 422 is located on the bottom surface of the lifting seat 421, when the lifting seat 421 descends, the bottom surface of each pressing column 422 abuts against the top surface of the product under test, applying a certain pressure to the product under test. Because the pressing surface 423 of each pressing column 422 is a straight surface, it increases the contact area between the pressing surface 423 and the top surface of the product under test, ensuring that the pressure applied to the product under test can tightly adhere the product to the bottom surface of the assembly cavity 21, thus fixing the product under test. After the product under test completes the testing process, the power output shaft of the second driver 41 pulls each pressing column 422 upwards until its pressing surface 423 separates from the top surface of the product under test, at which point the positioning fixture 2 or the product under test assembled in the positioning fixture 2 can be removed.

[0058] For example, there are four pressing posts 422 arranged in a circumferential array. With this arrangement, the pressing surfaces 423 of the four pressing posts 422 can be brought into contact with the circumferential edge of the top surface of the product to be tested and pressed down. This ensures that the pressure is evenly distributed on the top surface of the product and avoids excessive pressure at a single point, which could cause local deformation or crushing of the product.

[0059] It is understood that the pressing part 42 of this utility model embodiment is made of a material with elastic properties to prevent the product under test from being crushed due to excessive force applied to the pressing part 42 by the power output shaft of the second driver 41.

[0060] The second drive 41 can be understood as a cylinder, that is, the power output shaft of the cylinder is used to drive the lifting seat 421 to move up or down.

[0061] In a further embodiment, a support plate is provided on the workbench 1, and a guide rail is provided on the side of the support plate. The lifting seat 421 is provided with a moving part for moving the part provided on the guide rail. As such, the gas in the cylinder generates thrust after being pressurized, so as to push the power output shaft in the cylinder to move forward or backward. The power output shaft is connected to the lifting seat 421, that is, the thrust of the cylinder is transmitted to the lifting seat 421, so that the lifting seat 421 moves up or down along the guide rail, thereby driving each pressing column 422.

[0062] In some specific embodiments, the water injection assembly 31 includes a spray section 311 and a water pipe; the spray section 311 is disposed on the side of the movable seat 33 facing the product to be tested; one end of the water pipe is connected to the spray section 311, and the other end of the water pipe is connected to the water storage tank 12.

[0063] Specifically, the water storage tank 12 serves as a water supply system, pre-storing a large amount of water to be sprayed. The water storage tank 12 can stably supply water under different pressures and flow rates. During water supply, the water is transported to the spraying section 311 through a water pipe. Since the spraying direction of the spraying section 311 is towards the product to be tested, the spraying section 311 can play the role of injecting water into the product to be tested.

[0064] It should be noted that in order to deliver the water in the water storage tank 12 to the spray unit 311, a water pump for increasing the water pressure can be provided. This can be understood as an electric pump or a pneumatic pump, depending on the actual needs of the test equipment and the test requirements. The specific type is not limited here.

[0065] In some specific embodiments, the spray section 311 is formed with a bonding surface for adhering to the surface of the product to be tested.

[0066] Specifically, since the shape of the product under test is adapted to the contact surface, when the first driver 32 pushes the spraying part 311 to move toward the product under test, the contact surface of the spraying part 311 can completely contact the surface of the product under test. This is configured to ensure that when the product under test is subjected to a water injection test, the contact between the contact surface and the product under test is tighter, forming a sealing effect.

[0067] It is understandable that, since the waterproof and breathable membrane is installed on the wristband or watch, the surface on which the waterproof and breathable membrane is bonded is curved. Accordingly, the bonding surface of this utility model embodiment is curved.

[0068] In some specific embodiments, the testing apparatus also includes a drainage tank 11 disposed on the workbench 1, a positioning fixture 2 located above the drainage tank 11, and the positioning fixture 2 having a drain outlet for discharging accumulated water into the drainage tank 11.

[0069] Specifically, the drain tank 11 is located below the positioning fixture 2 and is used to collect the water discharged from the positioning fixture 2 to prevent the water from splashing onto the workbench 1 or other components in the test environment; the size and shape of the drain tank 11 are set according to the actual test requirements to ensure that it can hold a sufficient amount of water.

[0070] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
