Description

Technical Field

[0001] This utility model relates to the field of product airtightness testing technology, and in particular to an airtightness testing device with water detection function. Background Technology

[0002] In the product manufacturing field, such as automotive parts, consumer electronics, medical devices, outdoor lighting, and waterproof connectors, the sealing performance (air tightness) of a product is one of the key indicators determining its quality, safety, and service life. Currently, the mainstream methods for testing the sealing performance of workpieces mainly include air tightness testing and water tightness testing.

[0003] In current industrial production, airtightness testing and water tightness testing are usually considered two independent, sequential processes. Manufacturers need to purchase separate airtightness testing instruments and water tightness testing equipment (such as water testing boxes, water tanks, dryers, etc.), resulting in high equipment procurement costs and large floor space requirements. More importantly, operators need to handle, clamp, and position the workpiece between the two processes. This not only significantly reduces testing efficiency and prolongs the overall production cycle time, but also leads to misjudgments due to inconsistent positioning benchmarks during secondary clamping. For example, a leak detected by air tightness testing may not be reproducible during water tightness testing due to changes in the workpiece's posture, causing difficulties in quality problem analysis. Therefore, there is a need for a testing device that integrates airtightness testing and water tightness testing functions. To solve the above problems, we propose an airtightness testing device with integrated water tightness testing functionality. Utility Model Content

[0012] Alternatively, the bottom of the water collection tank is provided with an outlet, and a water bucket is provided below the outlet.

[0013] Beneficial effects:

[0014] 1. High integration, saving space and cost: This utility model integrates the clamping mechanism for air tightness testing and the water tank for water testing into the same testing platform through ingenious layout, replacing the traditional solution that requires two separate sets of equipment, significantly reducing the equipment footprint and lowering the overall purchase and maintenance costs.

[0015] 2. Improved testing efficiency: The workpiece only needs to be clamped between the upper and lower covers once, and air tightness and water tightness tests can be performed sequentially or selectively. This eliminates the need for handling and secondary clamping between workstations, greatly shortens the testing cycle, and improves production efficiency.

[0016] 3. Automated operation, more reliable results: The water tank's lifting and lowering is driven by a motor, ensuring smooth operation and accurate positioning, thus automating the water testing process. Simultaneously, because the workpiece's position remains fixed throughout the entire testing process, positioning errors caused by movement and reclamping are avoided, ensuring consistency between air and water testing standards and making the test results more reliable.

[0017] 4. Stable structure and good sealing: The lifting plate is slidably connected to the inner wall of the testing platform via a slide rail, ensuring the smoothness of the water tank's lifting process and reducing shaking. During water testing, the workpiece is completely enclosed in the water tank, ensuring comprehensive observation. The design of the through holes and plugs, as well as the cooperation between the water pump and the water collection tank, enables rapid and controllable water inlet and outlet, making it convenient and practical.

[0018] 5. Easy maintenance: The water collection tank and bucket ensure orderly drainage and maintain a clean working environment. The equipment has a reasonable structural design, with each functional module relatively independent, facilitating later inspection and maintenance. Attached Figure Description

[0028] Example 1

[0029] like Figure 1-5 As shown in the figure, this utility model embodiment provides an airtightness testing device with water detection function, including: a frame 12 is provided on the top of the testing platform 11, a support platform 13 is provided on the frame 12, and a lower cover 14 is provided on the support platform 13; a hydraulic rod 15 is provided on the frame 12, and an upper cover 16 is provided at the bottom of the hydraulic rod 15, with a pipe passing through the top of the upper cover 16; a water tank device 2 is provided on the testing platform 11, and the water tank device 2 includes: a motor 21 is provided on the outer wall of the testing platform 11, and the output end of the motor 21 passes through the testing platform 11. A rod body 22 is provided, and a gear 222 is provided at the other end of the rod body 22; a rod body 23 is rotatably disposed inside the detection table 11, and a gear 231 is sleeved on the rod body 23, with the gear 222 and the gear 231 meshing and connected; a screw 232 is threaded on the rod body 23; a lifting plate 24 is disposed on the top of the screw 232, and a water tank 25 is disposed on the top of the lifting plate 24; the lifting plate 24 is slidably connected to the inner side wall of the detection table 11, and the water tank 25 can accommodate the lower cover 14 and the upper cover 16.

[0030] Optionally, the testing platform 11 has an internal support frame 221, which is rotatably connected to the rod 22. Optionally, the inner sidewall of the testing platform 11 has symmetrically arranged slide rails 241, and the lifting plate 24 is slidably connected to the testing platform 11 via the slide rails 241. Optionally, the sidewall of the water tank 25 has symmetrically arranged through holes 251, which penetrate the testing platform 11, and a plug 252 is provided on the through hole 251 on the inner sidewall of the water tank 25. Optionally, the plug 252 is a rubber plug. Optionally, a water pump 26 is provided on the through hole 251 on one side of the testing platform 11. Optionally, a water collection tank 27 is provided on the outer sidewall of the through hole 251 on the other side of the testing platform 11. Optionally, an outlet 271 is provided at the bottom of the water collection tank 27, and a water bucket 28 is provided below the outlet 271.

[0031] This device mainly includes a testing platform 11 and a water tank device 2.

[0032] A frame 12 is fixedly mounted on the top of the testing table 11. A support platform 13 is provided on the frame 12, and a lower cover 14 for supporting the workpiece is installed on the support platform 13. A hydraulic rod 15 is also installed on the frame 12, with its piston rod pointing vertically downwards and an upper cover 16 installed at its end. A pipe is provided through the top of the upper cover 16 for connecting an external air source and pressure sensor to perform inflation, pressure holding, and pressure monitoring, thereby implementing airtightness testing.

[0033] The water tank device 2 is located entirely within the internal cavity of the testing platform 11. A motor 21 is fixedly mounted on the outer wall of the testing platform 11, with its output shaft horizontally extending inward into the testing platform 11 and connected to a rod 22. The rod 22 is rotatably supported by a support frame 221 fixed inside the testing platform 11. A gear 222 is fixedly mounted at the end of the rod 22. Inside the testing platform 11, a second rod 23 is also rotatably mounted in parallel. A gear 231 is fixedly fitted on the second rod 23, meshing with the aforementioned gear 222. The surface of the second rod 23 is machined with external threads, and a screw 232 is fitted on it, threadedly engaging with the screw 232. A lifting plate 24 is fixedly connected to the top of the screw 232. To ensure smooth lifting and lowering of the lifting plate 24, vertical slide rails 241 are symmetrically fixedly installed on the inner wall of the testing platform 11. The lifting plate 24 is slidably connected to the slide rails 241 via grooves or sliders on its side. A water tank 25 is fixedly installed on the top of the lifting plate 24. The internal space of the water tank 25 is large enough that when it rises to its highest point, it can completely enclose the lower cover 14 on the support platform 13 and the upper cover 16 after being pressed down by the hydraulic rod 15.

[0034] On each of the two symmetrical side walls of the water tank 25, there is a through hole 251, which also penetrates the side wall of the testing platform 11. A water pump 26 is connected to the outside of one of the through holes 251 to pump water into the water tank 25; a water collection tank 27 is installed on the outside of the other through hole 251 to collect water discharged from the water tank 25. The bottom of the water collection tank 27 has an outlet 271, below which a bucket 28 is placed to collect wastewater. Before water testing, a rubber plug 252 must be used to block the through hole 251 leading to the water collection tank 27 from the inside of the water tank to allow water to accumulate.

[0035] The actual operation process of this utility model is as follows:

[0036] 1. Workpiece clamping and airtightness testing: Activate hydraulic rod 15 to raise the upper cover 16. Place the workpiece to be tested on the lower cover 14, and activate hydraulic rod 15 again to press the upper cover 16 down and press the workpiece firmly onto the lower cover 14, forming a sealed cavity. Subsequently, inflate the workpiece through the pipes of the upper cover 16 to perform an airtightness test.

[0037] 2. Water Inspection Preparation: If a water inspection is required, start motor 21. Motor 21 drives rod 22 and gear 222 to rotate. Gear 222 drives gear 231 and rod 23 to rotate. Since rod 23 and screw 232 are threadedly connected, and the top of screw 232 is restricted from rotating by slide rail 241 via lifting plate 24, the rotation of rod 23 is converted into the vertical upward movement of screw 232 and the entire lifting mechanism (including lifting plate 24 and water tank 25).

[0038] 3. Water Inspection: After the water tank 25 rises to its highest position and completely submerges the workpiece, stop the motor. Use the water pump 26 to fill the water tank 25 with water until the workpiece is completely submerged. At this point, introduce low-pressure gas into the workpiece and observe whether bubbles emerge from its surface to determine the leak point.

[0039] 4. Reset: After the water test is completed, start the water pump 26 to pump the water back, or remove the plug 252 to allow the water to drain through the through hole 251 into the water collection tank 27, and finally into the water bucket 28. After the water is drained, start the motor 21 again to reverse the direction, driving the water tank 25 to descend to its original position inside the testing platform 11. Finally, the hydraulic rod 15 drives the upper cover 16 to rise, allowing the workpiece to be removed.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
