Description

Technical Field

[0001] This utility model relates to the field of breathable membrane waterproof testing technology, and in particular to a breathable membrane waterproof testing device for electronic products. Background Technology

[0002] Waterproof and breathable membranes allow air to pass through but not water. Therefore, they are typically placed at the vents of electronic products (watches, mobile phones, and tablets, etc.), such as speaker holes and balance holes, to provide waterproof and moisture-proof effects while ensuring breathability and sound transmission.

[0003] There are two main methods for testing the waterproof performance of waterproof and breathable membranes: flow rate testing and real water testing. The real water test involves injecting real water at a certain pressure into the outside of the membrane and determining its waterproof performance by measuring the amount of leakage. This method simulates actual working conditions, is intuitive and effective, and is therefore widely used.

[0004] Existing water testing equipment often leaves significant water residue inside the vents of electronic products after the water test. If subsequent production and assembly processes proceed directly, this can negatively impact speaker and microphone testing. Furthermore, the water may drip onto circuit components, causing damage. Manually drying with a hairdryer or wiping can leave watermarks on the breathable membrane, clogging it and affecting its breathability. It may also cause the adhesive on the breathable membrane to soften and fail. Additionally, it increases labor costs and reduces production and assembly efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a waterproof testing device for breathable membranes of electronic products. It can reduce the residual water in the vents of electronic products, avoid affecting subsequent speaker and microphone tests, reduce the potential damage risk of residual water to the breathable membrane and circuit components, and seamlessly connect with subsequent production and assembly processes to improve production and assembly efficiency and reduce production costs.

[0006] This utility model is achieved through the following technical solution: an electronic product breathable membrane waterproof testing device, including a base, and a product fixing device, a water injection testing device, a back suction device, a water absorption device and a control device disposed on the base;

[0007] The product fixing device is used to fix electronic products and breathable membrane;

[0008] The water injection detection device includes a first sealing component for sealing the vent hole of the electronic product, and a water injection component; the first sealing component is provided corresponding to the product fixing device, and a test pipe for communicating with the vent hole of the electronic product is provided through the first sealing component, and the test pipe is connected to the water injection component through the pipe;

[0009] The back-suction device includes a suction assembly, which is connected to the test pipeline via a pipe.

[0010] The water absorption device includes a water absorption fixture for fixing the electronic product, a second sealing member for sealing the air vent of the electronic product, and a first suction device; the second sealing member is disposed on one side of the water absorption fixture, and a suction pipe for communicating with the air vent of the electronic product is provided through the second sealing member, and the suction pipe is connected to the first suction device through a pipe.

[0011] Compared with the prior art, the electronic product breathable membrane waterproof testing equipment provided by this utility model fixes the electronic product and the breathable membrane with a product fixing device, seals the vent hole with a first sealing member, and has a test pipe that is connected to the vent hole through the first sealing member. The test pipe is connected to a water injection component through a pipe, and pressurized real water is injected into the vent hole through the water injection component. The suction component is connected to the test pipe through a pipe. After water is injected for a preset time, the real water in the vent hole is sucked away by the suction component. Finally, the electronic product after one water absorption is placed on a water absorption fixture, and the vent hole is sealed with a second sealing member, which has a suction pipe that is connected to the vent hole through the second sealing member. The first suction device is connected to the suction pipe through a pipe, and the residual real water in the vent hole is sucked away by the first suction device. Therefore, by using a back-suction device and a water-absorbing device, the amount of water residue in the vent holes of electronic products can be reduced, which can avoid affecting subsequent speaker and microphone tests and reduce the potential damage risk of water residue to the vent membrane and circuit components. After the electronic products are tested, they can be directly put into subsequent production and assembly processes without the need for manual wiping or drying of the water in the vent holes, which can improve production and assembly efficiency and reduce production costs.

[0012] Furthermore, the absorbent fixture is provided with a first contoured placement groove for fixing the electronic product. One side of the absorbent fixture is provided with a first clearance groove communicating with the first contoured placement groove. One end of the second sealing member is disposed within the first clearance groove and fits against the side of the electronic product. The suction pipe is connected to the vent hole of the electronic product. The first contoured placement groove facilitates the placement and fixing of the electronic product. The first clearance groove allows one end of the second sealing member to be disposed within the first clearance groove, enabling the electronic product placed in the first contoured placement groove to directly fit against the second sealing member, thereby sealing the vent hole.

[0013] Furthermore, the second sealing component is provided with a water-absorbing seal for adhering to the electronic product. The water-absorbing seal has a suction hole extending through it at a position corresponding to the vent of the electronic product. This suction hole is connected to both the vent of the electronic product and the suction pipe. The water-absorbing seal for adhering to the electronic product improves the sealing performance of the second sealing component, thus enhancing the water absorption effect.

[0014] Furthermore, it also includes a protective cover installed on the base. The product fixing device and the first sealing component are both disposed inside the protective cover, while the water-absorbing fixture and the second sealing component are both disposed outside the protective cover. Through the above arrangement, while water is injected into and drawn back into the vent of the electronic product, secondary water absorption can be performed simultaneously outside the protective cover on the vent of the electronic product that has already undergone water injection and back absorption, which helps to improve production and assembly efficiency.

[0015] Furthermore, the water injection detection device also includes a sealing actuator disposed on the base. The first sealing element is disposed at the output end of the sealing actuator, and the sealing actuator drives the first sealing element to move closer to or away from the vent of the electronic product. When the first sealing element moves closer to and seals the vent of the electronic product, the test pipe is connected to the vent of the electronic product. By using the sealing actuator, on the one hand, the first sealing element will not affect the placement of the electronic product, facilitating its placement; on the other hand, by driving the first sealing element to seal the vent after the electronic product is placed, gaps between the electronic product and the first sealing element can be avoided, resulting in a better sealing effect.

[0016] Furthermore, the product fixing device includes a carrier mounted on the base, and a pressing mechanism and a pressure fixture mounted above the carrier. The pressure fixture is located at the output end of the pressing mechanism. The carrier is provided with a second contoured placement slot for placing electronic products. Driven by the pressing mechanism, the pressure fixture presses and fixes the electronic products and the breathable membrane into the second contoured placement slot. The first contoured placement slot facilitates the positioning and placement of the electronic products. The pressing and fixing by the pressing mechanism and the pressure fixture prevents the electronic products from detaching from the first sealing component and the breathable membrane from falling off the electronic products, which would affect the testing.

[0017] Furthermore, one side of the carrier is provided with a second clearance groove that communicates with the second contour placement groove, one end of the first sealing member is disposed in the second clearance groove and fits against the side of the electronic product, and the test pipe is connected to the vent of the electronic product.

[0018] Furthermore, the press includes a press base, a product press block, and a breathable membrane press block; the pressing mechanism includes a pressing driver, the press base is elastically connected to the output end of the pressing driver, and both the product press block and the breathable membrane press block are located at the end of the press base away from the pressing driver, with the breathable membrane press block elastically connected to the press base. The elastic connection between the press base and the output end of the pressing driver prevents the press base from excessively pressing the carrier and the product press block from excessively pressing the electronic product. The elastic connection between the breathable membrane press block and the press base prevents the breathable membrane press block from excessively pressing the breathable membrane, thus preventing damage to the breathable membrane.

[0019] Furthermore, the first sealing component is provided with a water-filled seal for fitting with the electronic product. The water-filled seal has a water-filled hole extending through it at a position corresponding to the vent of the electronic product. This water-filled hole is connected to both the vent of the electronic product and the test pipe. The water-filled seal for fitting with the electronic product improves the sealing performance of the first sealing component.

[0020] Furthermore, the water injection assembly includes a water storage tank, a water injection pump connected to the water storage tank, and a first control valve connected to the water injection pump; the first control valve is connected to the test pipeline via a pipe; the suction assembly includes a second suction device and a second control valve connected to the second suction device, the second control valve being connected to the test pipeline via a pipe. Switching between water injection and backflow is achieved through the water injection pump, the first control valve, the first suction device, and the second control valve.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] like Figures 1 to 8As shown, this embodiment provides an electronic product breathable membrane waterproof testing device, including a base 10, and a product fixing device 20, a water injection testing device 30, a back suction device (not shown), a water absorption device (40), and a control device (not shown) disposed on the base 10. The product fixing device 20 is used to fix the electronic product 70 and the breathable membrane 71; the water injection testing device 30 is used to inject pressurized test water into the electronic product's vent 72; the back suction device is used to perform a primary water absorption on the electronic product's vent 72; the water absorption device 40 is used to perform a secondary water absorption on the electronic product's vent 72; the control device is electrically connected to the product fixing device 20, the water injection testing device 30, the back suction device, and the water absorption device 40, respectively, and is used to control the working status of the product fixing device 20, the water injection testing device 30, the back suction device, and the water absorption device 40.

[0033] The electronic product breathable membrane waterproof testing equipment provided in this embodiment uses a back-suction device and a water-absorbing device 40 to perform a first and second water absorption on the water-filled electronic product's breathable holes 72, respectively. This reduces the amount of water residue in the breathable holes 72 after the water test, preventing subsequent speaker and microphone tests from being affected and reducing the potential damage risk of water residue to the breathable membrane 71 and circuit components. Furthermore, the tested electronic product 70 can be directly proceeded to subsequent production and assembly processes without the need for manual wiping or drying of the water in the breathable holes 72, thereby improving production and assembly efficiency and reducing production costs.

[0034] The following is a detailed description of the specific structure of the breathable membrane waterproof testing equipment for electronic products.

[0035] like Figure 3 as well as Figure 5 As shown, the product fixing device 20 includes a carrier 21 disposed on the base 10, and a pressing mechanism 22 and a pressure fixture 23 disposed above the carrier 21. The pressure fixture 23 is disposed at the output end of the pressing mechanism 22; the carrier 21 is provided with a second contoured placement groove 211 for placing the electronic product 70. Under the drive of the pressing mechanism 22, the pressure fixture 23 presses and fixes the electronic product 70 and the breathable membrane 71 in the second contoured placement groove 211.

[0036] The pressure fixture 23 includes a pressure base 231, a product pressure block 232, and a breathable membrane pressure block 233. The pressing mechanism 22 includes a pressing driver (not shown). The pressure base 231 is located at the output end of the pressing driver. The product pressure block 232 and the breathable membrane pressure block 233 are both located at the end of the pressure base 231 away from the pressing driver. Under the drive of the pressing driver, the pressure base 231 abuts against the carrier 21, and the product pressure block 232 and the breathable membrane pressure block 233 press and fix the electronic product 70 and the breathable membrane 71 respectively in the first contour placement groove 211. The first contour placement groove 211 facilitates the positioning and placement of the electronic product 70; the product pressure block 232 prevents the electronic product 70 from detaching from the first contour placement groove 211, and the breathable membrane pressure block 233 prevents the breathable membrane 71 from detaching from the electronic product 70, thereby avoiding any impact on the testing. In this embodiment, the pressure base 231, product pressure block 232, and breathable membrane pressure block 233 are all separate designs. Of course, in other alternative embodiments, the pressure base 231 can be integrated with the product pressure block 232 and / or the breathable membrane pressure block 233. In this embodiment, the downward pressure actuator is a drive cylinder. Of course, in other alternative embodiments, the downward pressure actuator can be a drive motor, which is connected to the pressure base 231 via a linear transmission mechanism. The linear transmission mechanism is a mechanism that converts rotary motion into linear motion.

[0037] In this embodiment, the pressure seat 231 is elastically connected to the output end of the pressure driver. Specifically, the pressure mechanism further includes a connecting seat 221 disposed at the output end of the pressure driver. At least one connecting post 2313 is disposed on the side of the pressure seat 231 facing the connecting seat 221, and the connecting post 2313 is slidably connected to the connecting seat 221. The product fixing device 20 further includes a first elastic element 25, which is disposed between the pressure seat 231 and the connecting seat 221 and sleeved on the connecting post 2313. Through the slidable connection between the connecting post 2313 on the pressure seat 231 and the connecting seat 221, and by providing the first elastic element 25 between the pressure seat 231 and the connecting seat 221, the pressure seat 231, the product pressure block 232, and the breathable membrane pressure block 233 have a certain buffering capacity during the pressing process, preventing damage to the carrier 21, the electronic product 70, and the transparent film 71. In this embodiment, the first elastic element 25 is a spring. Of course, in other alternative embodiments, the first elastic element 25 can be other elastic elements such as rubber elastic elements.

[0038] In this embodiment, the pressure seat 231 includes a pressure seat body 2311 and a connecting block 2312 detachably assembled with the pressure seat body 2311. The connecting block 2312 is disposed on the side of the pressure seat body 2311 facing the connecting seat 221, and the connecting block 2312 is provided with the connecting post 2313. The product pressure block 232 and the breathable membrane pressure block 233 are disposed on the side of the pressure seat body 2311 facing away from the connecting block 2312. The detachable assembly design of the pressure seat body 2311 and the connecting block 2312 allows for replacement of the pressure seat body 2311 according to the product model, improving the applicability of the equipment. The pressure seat body 2311 and the connecting block 2312 can be connected by detachable methods such as screws or clips, and this is not limited. Of course, in other alternative embodiments, the pressure seat body 2311 and the connecting block 2312 can also be a single integrated design.

[0039] In this embodiment, the breathable membrane pressure block 233 is elastically connected to the pressure base body 2311. Specifically, the pressure base body 2311 is provided with a breathable membrane pressure block mounting groove (not shown) at the position corresponding to the breathable membrane 71. The product fixing device 20 also includes a second elastic element (not shown), which is disposed in the breathable membrane pressure block mounting groove. One end of the breathable membrane pressure block is disposed in the breathable membrane pressure block mounting groove and is disposed on the inner wall of the breathable membrane pressure block mounting groove through the second elastic element, while the other end protrudes from the breathable membrane pressure block mounting groove and the pressure base body 2311. The second elastic element can further prevent the breathable membrane pressure block 233 from excessively compressing the breathable membrane 71 and causing damage to the breathable membrane 71. In this embodiment, the second elastic element is a spring. Of course, in other alternative embodiments, the second elastic element can be a rubber elastic element or other elastic elements.

[0040] In this embodiment, the pressing mechanism further includes a guide assembly connected to the connecting seat 221. The guide assembly includes a guide rail 222 arranged vertically and a slider 223 slidably disposed on the guide rail 222. The connecting seat 221 is connected to the slider 223. The guide assembly improves the accuracy and stability of the pressing motion of the press 23. Of course, in other alternative embodiments, the guiding of the press 23 is not limited to the guide rail 222 and the slider 223. For example, a vertically extending guide groove can be provided, and a corresponding guide protrusion can be provided on the connecting seat. The pressing motion of the press 23 can also be guided by the guide groove and the guide protrusion.

[0041] In this embodiment, the pressure base body 2311 is provided with a plurality of guide posts on the side facing the carrier 21, and the carrier is provided with guide holes corresponding to the guide posts, the guide holes matching the guide posts. The guide posts and guide holes improve the accuracy and stability of pressing and fixing the breathable membrane pressure block 233 and the product pressure block 232.

[0042] In this embodiment, the product fixing device 20 further includes a mounting base 24, which is disposed on the base 10, and the carrier 21 is detachably disposed on the mounting base 24. The detachable arrangement of the carrier 21 helps to improve the applicability of the equipment.

[0043] like Figure 3 and Figure 5 As shown, the water injection detection device 30 includes a first sealing member 31 for sealing the vent hole and a water injection component; the first sealing member 31 is provided corresponding to the carrier 21, and a test pipe 32 for communicating with the vent hole 72 of the electronic product is provided through the first sealing member 31. The test pipe 32 is connected to the water injection component through a pipe.

[0044] In this embodiment, the first sealing member 31 is movably disposed on the base 10. Specifically, the water injection detection device 30 further includes a sealing actuator 33 disposed on the base 10, and the first sealing member 31 is disposed at the output end of the sealing actuator 33. The sealing actuator 33 drives the first sealing member 31 to move closer to or away from the electronic product vent 72. When the first sealing member 31 moves closer to and blocks the electronic product vent 72, the test pipe 32 is connected to the electronic product vent 72. By setting the sealing actuator 33, on the one hand, the first sealing member 31 will not affect the placement of the electronic product 70, so as to facilitate the placement of the electronic product 70; on the other hand, after the electronic product 70 is placed, the sealing actuator 33 drives the first sealing member 31 to block the electronic product vent 72, which can avoid the gap between the electronic product 70 and the first sealing member 31, and the sealing effect is better. In this embodiment, the sealing actuator 33 is a driving cylinder. Of course, in other alternative embodiments, the blocking actuator 33 may be a drive motor, which is connected to the first blocking element via a linear transmission mechanism.

[0045] In this embodiment, one side of the carrier 21 is provided with a second clearance groove 212 that communicates with the second contour placement groove 211. One end of the first sealing member 31 is disposed in the second clearance groove 212 and fits against the side of the electronic product 70. The placement of one end of the first sealing member 31 in the second clearance groove 212 contributes to the compact design of the device and helps reduce the number of connecting parts. In this embodiment, the first sealing member 31 has a T-shaped structure, including a first sealing seat 311 and a first sealing head 312 vertically disposed at one end of the first sealing seat 311. Both the first sealing seat 311 and the first sealing head 312 have water injection pipes that extend through them, and the water injection pipes are interconnected to form the test pipe 32. The end of the first sealing seat 311 facing away from the first sealing head 312 is connected to the sealing driver 33. In this embodiment, the first sealing seat 311 and the first sealing head 312 are an integral design. Of course, in other alternative embodiments, the first sealing seat 311 and the first sealing head 312 can be a separate design, and can be connected by screws, clips, welding or bonding. Also, in other alternative embodiments, the first sealing component 31 is not limited to a T-shaped structure, and can be other structural forms, such as a cuboid sealing block, or an irregular shape designed according to actual conditions.

[0046] In this embodiment, the water injection detection device 30 further includes a limiting block 35 disposed on the base 10. The limiting block 35 is disposed on one side of the carrier 21 corresponding to the vent 72 of the electronic product, and is located between the carrier 21 and the sealing driver 33. When the first sealing head 312 approaches the vent 72 of the electronic product, the first sealing seat 311 abuts against the limiting block 35. The limiting block 35 limits the first sealing member 31, preventing the first sealing member 31 from excessively pressing against the electronic product 70 and causing damage to the electronic product 70.

[0047] In this embodiment, the first sealing head 312 is provided with a water-filled sealing element 34 for fitting with the electronic product 70. The water-filled sealing element 34 has a water-filled hole 341 through it at the position corresponding to the vent hole 72 of the electronic product. The water-filled hole 341 is connected to the vent hole 72 of the electronic product and the test pipe 32. Specifically, the first sealing head 312 has a first receiving groove 3121 at one end near the carrier 21. One end of the water-filled sealing element 34 is disposed in the first receiving groove 3121, and the other end is fitted with the side of the electronic product 70. The water-filled sealing element 34 for fitting with the electronic product 70 improves the sealing performance of the first sealing element 31. The water-filled sealing element 34 in this embodiment can be made of rubber materials (such as silicone, nitrile rubber, etc.) or plastic materials.

[0048] In this embodiment, the water injection assembly includes a water storage tank 36, a water injection pump connected to the water storage tank 36, and a first control valve connected to the water injection pump; the first control valve is connected to the test pipeline 32 via a pipe. Real water at a certain pressure is injected into the electronic product's vent 72 by the water injection pump for testing, and the first control valve controls the opening and closing of the test pipeline 32. The back-suction device includes a suction assembly connected to the test pipeline 32 via a pipe. The suction assembly includes a second suction device and a second control valve connected to the second suction device, which is connected to the test pipeline 32 via a pipe. Switching between water injection and back-suction is achieved through the water injection pump, the first control valve, the second suction device, and the second control valve. In this embodiment, the second suction device is a vacuum suction device. Of course, in other alternative embodiments, the second suction device can be a suction pump.

[0049] In some optional embodiments, the second suction device is connected to the water storage tank 36. Specifically, the water storage tank 36 includes a connected injection tank and a collection tank, the injection pump is connected to the injection tank, and the second suction device is connected to the collection tank. Thus, the recycling of real water is achieved through the above-described device. Preferably, the collection tank is connected to the injection tank via a filtration device. This reduces impurities in the re-injected real water through the filter.

[0050] like Figure 4 As shown, the water absorption device 40 includes a water absorption fixture 41 for fixing the electronic product 70, a second sealing member 42 for sealing the air vent 72 of the electronic product, and a first suction device (not shown). The second sealing member 42 is disposed on one side of the water absorption fixture 41, and a suction pipe 43 for communicating with the air vent 72 of the electronic product is provided through the second sealing member 42. The suction pipe 43 is connected to the first suction device through a pipe.

[0051] Specifically, the absorbent fixture 41 is provided with a first contoured placement groove 411 for fixing the electronic product 70. One side of the absorbent fixture 41 is provided with a first clearance groove 412 communicating with the first contoured placement groove 411. One end of the second sealing member 42 is disposed within the first clearance groove 412 and is in contact with the side of the electronic product 70. The suction pipe 43 is connected to the vent hole 72 of the electronic product. The first contoured placement groove 411 facilitates the placement and fixing of the electronic product 70. The first clearance groove 412 allows one end of the second sealing member 42 to be disposed within the first clearance groove 412, enabling the electronic product 70 placed in the first contoured placement groove 411 to directly contact the second sealing member 42, thereby sealing the vent hole 72 of the electronic product.

[0052] In this embodiment, the second sealing member 42 is also a T-shaped structure, including a second sealing seat 421 and a second sealing head 422 vertically disposed at one end of the second sealing seat 421. The second sealing head 422 is disposed corresponding to the vent 72 of the electronic product. Both the second sealing seat 421 and the second sealing head 422 are provided with water suction pipes, which are interconnected to form the suction pipe 43. In this embodiment, the second sealing seat 421 and the second sealing head 422 are an integral design. Of course, in other alternative embodiments, the second sealing seat 421 and the second sealing head 422 can be a separate design, which can be connected by screws, clips, welding or bonding. Of course, in other alternative embodiments, the second sealing member 41 is not limited to a T-shaped structure, and can be other structural forms, such as the second sealing member 41 being a cuboid-shaped sealing block, or an irregular shape designed according to actual conditions.

[0053] In this embodiment, the second sealing member 41 is provided with a water-absorbing seal for adhering to the electronic product. Specifically, the water-absorbing seal has a suction hole through it at the position corresponding to the vent hole 72 of the electronic product, and the suction hole is connected to both the vent hole 72 and the suction pipe 43. The structure of the water-absorbing seal is similar to that of the water-injection seal, and will not be described again here.

[0054] Specifically, the second sealing head 422 has a second receiving groove at one end near the water-absorbing fixture 41. One end of the water-absorbing seal is disposed in the second receiving groove, and the other end protrudes from the second receiving groove and is in contact with the side of the electronic product 70. The water-absorbing seal, used to fit against the electronic product 70, improves the sealing performance of the second sealing member 41, thus enhancing the water absorption effect. In this embodiment, the water-absorbing seal can be made of rubber (such as silicone, nitrile rubber, etc.) or plastic materials.

[0055] In this embodiment, the water absorption device further includes a sensor for sensing the electronic product. The sensor is configured to correspond to the water absorption fixture and is electrically connected to the control device. Through the sensor, once the electronic product is placed in the first contour placement slot, the first suction device can be controlled to perform secondary water absorption from the electronic product's vent holes.

[0056] In some alternative implementations, the first suction device is also connected to the collection tank to recover real water. In this embodiment, the first suction device is a vacuum suction device. Of course, in other alternative implementations, the first suction device can be a suction pump.

[0057] In this embodiment, the electronic product breathable membrane waterproof testing equipment further includes a protective cover 60 covering the base 10. The product fixing device 20, the first sealing member 31, and the sealing driver 33 are all disposed inside the protective cover 60; the water-absorbing fixture 41 and the second sealing member 42 are all disposed outside the protective cover 60. With the above arrangement, while performing water injection and back-suction operations into the electronic product vent 72, a secondary water absorption can be performed on the electronic product vent 72 outside the protective cover 60 after water injection and back-suction have been completed, which helps to improve production assembly efficiency.

[0058] The control device is electrically connected to the pressure drive, the sealing drive 33, the water injection pump, the first control valve, the first suction device, the second suction device, and the second control valve, respectively.

[0059] In this embodiment, the carrier 21 is provided with a second handle opening 213, which is disposed on both sides of the second contour placement groove 211 and communicates with the second contour placement groove 211. The second handle opening 213 facilitates the taking and placing of the electronic product 70.

[0060] In this embodiment, the absorbent fixture 41 is provided with a first handle opening 413, which is located on both sides of the first contoured placement groove 411 and communicates with it. The first handle opening 413 facilitates the placement and retrieval of the electronic product 70.

[0061] In this embodiment, the electronic product breathable membrane waterproof testing device further includes a collection box 50, which is located below the carrier 21 and disposed on the base 10. The mounting base 24 has a drain outlet at the position corresponding to the electronic product vent 72, and the drain outlet is connected to the collection box 50. Through the collection box 50, in the event that the first sealing member 31 does not completely seal the electronic product vent 72, or water leakage occurs during the water injection process, real water can be prevented from entering the device and causing damage.

[0062] In this embodiment, the protective cover 60 has an electronic product loading / unloading port 61 on its front side, which is positioned corresponding to the carrier 21. Safety light curtains are provided on both sides of the electronic product loading / unloading port 61. It also includes a start button and an emergency stop button; the start button and emergency stop button are located outside the protective cover and are mounted on the base. Both the start button and emergency stop button are electrically connected to the control device.

[0063] In this embodiment, there are two carriers 21 and two water-absorbing fixtures 41. The two carriers 21 and the two water-absorbing fixtures 41 are symmetrically arranged on the base 10. This dual-station configuration improves testing efficiency.

[0064] When performing waterproof testing on the vent holes of electronic products, the electronic product is first placed in the second contour placement slot, and then the start button is pressed. After receiving the start signal, the control device controls the pressure driver to press down, pressing and fixing the electronic product and the breathable membrane in the second contour placement slot. Then, the sealing driver is controlled to drive the first sealing device to seal the vent holes of the electronic product. After sealing, the first control valve is opened, and the water injection pump is controlled to inject real water at a certain pressure into the vent holes of the electronic product. After injecting real water for a preset time, the first control valve and the water injection pump are closed, and the second control valve and the second suction device are opened to perform a first water suction on the vent holes of the electronic product. After suction for a certain period of time, the pressure driver and the sealing driver are controlled to return to their original positions. The electronic product is then removed, placed in the first contour placement slot, and the first suction device is controlled to perform a second water suction on the vent holes of the electronic product. After suction for a certain period of time, the electronic product is removed, and the presence of water droplets on the surface of the breathable membrane inside the electronic product is manually checked to complete the test.

[0065] Compared with the prior art, the electronic product breathable membrane waterproof testing equipment provided by this utility model fixes the electronic product and the breathable membrane with a product fixing device, seals the vent hole with a first sealing member, and has a test pipe that is connected to the vent hole through the first sealing member. The test pipe is connected to a water injection component through a pipe, and pressurized real water is injected into the vent hole through the water injection component. The suction component is connected to the test pipe through a pipe. After water is injected for a preset time, the real water in the vent hole is sucked away by the suction component. Finally, the electronic product after one water absorption is placed on a water absorption fixture, and the vent hole is sealed with a second sealing member, which has a suction pipe that is connected to the vent hole through the second sealing member. The first suction device is connected to the suction pipe through a pipe, and the residual real water in the vent hole is sucked away by the first suction device. Therefore, by using a back-suction device and a water-absorbing device, the amount of water residue in the vent holes of electronic products can be reduced, which can avoid affecting subsequent speaker and microphone tests and reduce the potential damage risk of water residue to the vent membrane and circuit components. After the electronic products are tested, they can be directly put into subsequent production and assembly processes without the need for manual wiping or drying of the water in the vent holes, which can improve production and assembly efficiency and reduce production costs.
