Description

Technical Field

[0001] This specification relates to the field of aluminum panel testing technology, and more particularly to a device for testing the waterproof performance of aluminum panels. Background Technology

[0002] Aluminum single-layer panels are widely used in building exterior walls and interior decoration due to their advantages such as light weight, high strength, corrosion resistance, and good decorative properties. In practical applications, aluminum single-layer panels are often exposed to the elements or humid environments, and their waterproof performance directly affects their service life and safety. Therefore, after the production and processing of aluminum single-layer panels, their waterproof performance must be strictly tested.

[0003] Existing aluminum panel waterproof performance testing devices mostly employ a simple method of rain spraying combined with visual observation, which has several shortcomings: First, the testing accuracy is low, making it difficult to accurately identify minor or hidden seepage, leading to missed detections. Second, the fixing mechanism has poor stability; if the aluminum panels are not securely fixed or properly sealed, sprayed water can easily leak from the edges, interfering with the accuracy of the test results. Third, there is a lack of an efficient seepage location mechanism; even if seepage is detected, it is difficult to quickly pinpoint the exact location, hindering subsequent rectification. Fourth, the water accumulated after spraying during the test cannot be drained in a timely manner, and long-term accumulation can corrode the device structure and affect the continuity of subsequent tests.

[0004] To address the problems of low accuracy in testing the waterproof performance of aluminum panels, poor sealing effect, difficulty in locating seepage, and untimely drainage in existing technologies, there is an urgent need to develop a waterproof performance testing device for aluminum panels that is accurate in detection, reliable in fixation, can quickly locate seepage, and facilitates drainage. Summary of the Invention

[0005] In view of this, the purpose of one or more embodiments of this specification is to provide a waterproof performance testing device for aluminum single-panel panels to solve the problem.

[0011] Preferably, an inclined silicone pad is also provided during the workpiece clamping process, which can achieve sealing of the workpiece edge.

[0014] Preferably, after the workpiece is fixedly installed by the upper and lower clamping plates, the distance between the end of the water pipe extending to the inside of the upper bracket and the workpiece is 3-5 mm.

[0015] Preferably, the upper support has a rectangular structure, and linear laser lights are respectively provided on both sides of the bottom end of the inner wall of the upper support.

The aluminum single plate is stably clamped by the bolt cooperation between the upper and lower clamping plates. At the same time, the inclined silicone pads achieve a tight seal on the edge of the workpiece, which avoids water leakage from the edge during the test and prevents interference with the test results, thus ensuring the accuracy of the test.

[0021] 3. High integration of functions and wide applicability: The device integrates multiple functions such as waterproof detection, water seepage location, and bulge detection. It can simultaneously detect the bulge on the surface of aluminum panels under water immersion conditions using a linear laser light, without the need for additional testing equipment. At the same time, the device's fixing mechanism can be adapted to aluminum panels of different specifications, making it widely applicable and reducing the company's investment cost in testing equipment.

[0031] Example 1:

[0032] like Figure 1-5 As shown, a waterproof performance testing device for aluminum single-panel is provided, including a base frame 1 and an upper support 2. The upper support 2 is provided with a workpiece fixing device for fixing workpieces, a rain shower device, a water pumping device, and a bulge laser detection device.

[0033] The workpiece fixing device is located on both sides of the upper bracket 2, and two sets are set on each side to fix the workpiece at four points to make the fixing effect better. The workpiece fixing device consists of an upper pressure plate 22 and a lower pressure plate 27. The lower pressure plate 27 is fixed to the upper pressure plate 22 by bolts.

[0052] Sufficient powder is injected into the powder chamber 11, and it is necessary to ensure that the powder is in a fluffy state. This allows the aeration pump to fully pump a large amount of powder into the groove 12 and gap between the base frame 1 and the upper support 2 during use. When water seepage occurs on the workpiece, the humidity of its bottom surface is different. After the powder enters, it will accumulate and stick to the area with higher humidity, thus determining whether water seepage has occurred.

[0053] The injected powder can be replaced with a powder of a different color than the back of the workpiece when necessary, thereby increasing its recognizability.

[0066] An embedded groove 13 is provided on the upper surface of the base frame 1, a groove 12 is provided at the center of the upper surface of the base frame 1, a sponge pad 17 is provided at the four corners of the lower surface of the base frame 1, and a powder chamber 11 is also provided on the base frame 1.

[0067] Sufficient powder is injected into the powder chamber 11, and it is necessary to ensure that the powder is in a fluffy state. This allows the aeration pump to fully pump a large amount of powder into the groove 12 and gap between the base frame 1 and the upper support 2 during use. When water seepage occurs on the workpiece, the humidity of its bottom surface is different. After the powder enters, it will accumulate and stick to the area with higher humidity, thus determining whether water seepage has occurred.

[0068] The injected powder can be replaced with a powder of a different color than the back of the workpiece when necessary, thereby increasing its recognizability.

[0069] During the workpiece clamping process, the inclined silicone pad 26 achieves a better edge sealing effect during use.

[0070] Auxiliary inner cavity frames 23 are provided at the top of both sides of the upper support 2. An air hole frame 3 is provided on the upper surface of the auxiliary inner cavity frame 23, and multiple connecting holes 31 are provided on the air hole frame 3.

One end of the spray nozzle 34 passes through the upper support 2 and the auxiliary inner cavity frame 23 and communicates with each other inside the auxiliary inner cavity frame 23.

[0071] The water used was kept at room temperature to avoid condensation affecting the test results.

[0072] The upper support 2 below the spray nozzle 34 is inlaid with two sets of water pumping pipes 32, with one end of the water pumping pipe passing through the upper support 2 and the other end extending to the inner side of the upper support 2 near the bottom.

[0075] The linear laser lamp 25 effectively detects whether bulges appear on the surface of the workpiece when it is soaked in water.

[0076] When conducting a water immersion and waterproofing test on the workpiece, an appropriate amount of water is injected into the upper support 2 through the spray nozzle 34, and water seepage is detected from below. At the same time, the surface is effectively detected for bulging under the action of a linear laser lamp from above.

[0077] Working principle: During use, the surface of the workpiece fixed below the upper support 2 is sprayed with water through the spray nozzle 34 to detect water seepage. During the water seepage test, sufficient powder is injected into the powder chamber 11, and the powder must be in a fluffy state. This allows the air pump to fully pump a large amount of powder into the groove 12 and gap between the base frame 1 and the upper support 2. When water seepage occurs on the workpiece, the humidity of its bottom surface varies. After the powder enters, it will accumulate and stick to the areas with higher humidity, thus determining whether water seepage has occurred. When conducting a water immersion waterproof test on the workpiece, an appropriate amount of water is injected into the upper support 2 through the spray nozzle 34, and water seepage is detected from below. At the same time, the surface is effectively detected for bulging under the action of a linear laser lamp from above.
