Description

Technical Field

[0001] This application relates to the field of xenon lamp testing equipment technology, and in particular to a flat-panel xenon lamp aging test chamber. Background Technology

[0002] A xenon lamp aging test chamber is a device that uses a xenon arc lamp to simulate solar radiation and conduct artificial accelerated aging tests on materials. Its core principle is to reproduce the ultraviolet, visible, and infrared spectra of sunlight by using the full spectrum of light emitted by the xenon lamp, and to accelerate the aging process of materials in a laboratory by precisely controlling environmental factors such as temperature, humidity, and spraying.

[0003] This equipment helps researchers and manufacturers quickly assess the weather resistance of materials and predict their lifespan in real-world environments. In industrial production and materials research, materials and products are exposed to the natural environment for extended periods during actual use, affected by factors such as solar radiation, rain, and temperature changes. This can lead to aging phenomena such as fading, cracking, and performance degradation. Therefore, aging tests are necessary to assess their aging resistance in advance. Existing sample aging test devices typically place samples directly on a fixed sample holder. If the shape and volume of the samples change, the holder cannot adjust the distance between samples according to their condition. This can cause interference between samples, resulting in significant differences in temperature and light exposure in different areas of the sample, poor data consistency, and negatively impacting the test results. Summary of the Invention

[0004] To improve the ease of operation of the flat-panel xenon lamp aging test chamber, this application provides a flat-panel xenon lamp aging test chamber.

[0005] This application provides a flat-panel xenon lamp aging test chamber, which adopts the following technical solution: A flat-panel xenon lamp aging test chamber includes a chassis, a test chamber mounted on the chassis, a carrier plate mounted on the test chamber, a first transfer assembly and / or a second transfer assembly for placing samples mounted on the carrier plate, and a water spray assembly, a ventilation assembly, and a light irradiation assembly simulating sunlight irradiation mounted on the chassis.

[0006] By adopting the above technical solution, and by setting an adjustable first transfer component and / or second transfer component on the carrier plate, the placement position and spacing of the sample can be flexibly adjusted according to the shape and volume of the sample, avoiding shading interference between samples, ensuring uniform temperature and light exposure in each area of ​​the sample, and improving the consistency of test data. At the same time, the spray component, ventilation component and lighting component work together to accurately simulate various aging factors in the natural environment, realizing comprehensive and efficient testing of the weather resistance of materials. The overall structural design is reasonable and the ease of operation is greatly improved.

[0007] In one specific implementation, the carrier plate is provided with a sliding groove, the first transfer component includes a slide, the slide is slidably mounted on the carrier plate through the sliding groove, the carrier plate is provided with a slot for adjusting the position of the slide, the slot is connected to the sliding groove, and a locking block is installed on the slide that engages with the slot.

[0008] By adopting the above technical solution, the slide can be adjusted along the direction of the slide by sliding with the carrier plate through the slide groove. Then, by the locking block and the locking with different slots, the adjusted position of the slide can be quickly fixed, making the operation simple and efficient. The design of the slots and slide grooves being connected and equally spaced makes the position adjustment of the slide more precise and orderly, meeting the spacing adjustment requirements of samples of different sizes, and further improving the adaptability and ease of operation of the test chamber.

[0009] In one specific implementation, the second transfer assembly includes a fixed disk with two or more adjustment slots. A movable block is slidably mounted on the fixed disk through the adjustment slots. A fixed rod is mounted on the fixed disk, and a turntable is rotatably mounted on the fixed rod. A swing arm is hinged to the turntable, and the end of the swing arm away from the turntable is hinged to the movable block.

[0010] By adopting the above technical solution, the multiple adjustment slots on the fixed plate provide sliding guides for the movable blocks. When the turntable is rotated, the transmission action of the swing arm can drive the multiple movable blocks to slide synchronously along the adjustment slots, realizing the synchronous adjustment of the sample placement position. Compared with a single adjustment movable block, the adjustment efficiency is higher. At the same time, this linkage adjustment structure can ensure that the adjustment range of each movable block is consistent, so that the spacing between samples remains uniform, effectively avoiding the spacing deviation caused by manual individual adjustment and ensuring the consistency of test conditions.

[0011] In one specific implementation, the fixed plate includes two opposing adjustment slots, a rod is installed on the movable block, the rod has a first locking hole, a sleeve is installed on the movable block, the sleeve has a second locking hole, the sleeve and the rod are respectively installed on the two opposing movable blocks, the sleeve and the rod are slidably connected, and a locking rod is inserted into the sleeve and the rod.

[0012] By adopting the above technical solution, the sliding engagement between the insert rod and the sleeve on the relatively set movable block can guide and limit the sliding of the movable block, ensuring that the movable block slides smoothly along the adjustment groove. When the movable block is adjusted to the target position, the locking rod is inserted into the corresponding first and second locking holes to fix the insert rod and the sleeve, thereby locking the position of the movable block and preventing the movable block from shifting due to vibration and other factors during the test, thus ensuring the stability of the test process and the accuracy of the test results.

[0013] In one specific implementation scheme, a telescopic rod is installed on the movable block, a telescopic sleeve is slidably installed on the telescopic rod, a lifting plate for placing samples is installed on the telescopic sleeve, a connecting plate is installed on the fixed rod, a support rod is hinged to the connecting plate, and the end of the support rod away from the connecting plate is hinged to the lifting plate.

[0014] By adopting the above technical solution, the sliding cooperation between the telescopic rod and the telescopic sleeve provides guiding support for the lifting of the lifting plate, while the hinged cooperation between the support rod and the connecting plate and the lifting plate allows the moving block to slide along the adjustment groove, and the swing of the support rod can drive the lifting plate to rise and fall synchronously, realizing flexible adjustment of the sample height. This structural design can adjust the distance between the sample and the light and spray components according to the test requirements, further optimize the light and spray conditions of the sample, make the aging environment simulation more accurate, and improve the test function diversity of the test chamber.

[0015] In one specific implementation, the lever is L-shaped.

[0016] By adopting the above technical solution, the design of the L-shaped rocker arm can optimize the hinge position relationship between the rocker arm, the turntable, and the movable block, achieving a larger transmission stroke within a limited space and ensuring that the movable block can slide along the adjustment groove to the required position. At the same time, compared with the straight rocker arm, the L-shaped structure experiences more stable force during transmission, reduces stress concentration, improves the structural strength and service life of the rocker arm, and ensures the long-term stable operation of the adjustment function of the second transfer component.

[0017] In one specific implementation, the spray assembly includes a water tank mounted on the chassis and positioned below the test chamber. A water pump is installed inside the water tank. A water pipe is installed on the chassis, with one end of the water pipe connected to the water pump inside the water tank and the other end extending into the test chamber. A nozzle is installed at the end of the water pipe extending into the test chamber. A return pipe is installed on the test chamber and communicates with the water tank.

[0018] By adopting the above technical solution, the water tank is located below the test chamber, which facilitates the collection of returned spray water, realizing the recycling of water resources and making it more energy-efficient and environmentally friendly. The water pump provides power for spraying and delivers water from the tank to the nozzles through water pipes. The nozzles can spray water evenly onto the samples, simulating the environment of natural rainwater washing. The return pipe returns the water accumulated in the test chamber to the water tank, forming a complete water circulation system. There is no need for frequent water addition and drainage, which simplifies the operation process and improves the convenience and practicality of the test chamber.

[0019] In one specific implementation, the ventilation assembly includes a fan mounted on the chassis, a ventilation duct connected to the fan, and the end of the ventilation duct away from the fan leading into the test chamber.

[0020] By adopting the above technical solution, the fan introduces air into the test chamber through the ventilation pipe, which can realize the air circulation in the test chamber, simulate the wind conditions in the natural environment, and accelerate the aging of the sample.

[0021] In one specific implementation, the illumination assembly includes a lampshade mounted on the chassis, the lampshade being in communication with the test chamber, and a xenon lamp mounted on the lampshade.

[0022] By adopting the above technical solution, the lamp cover protects and focuses the xenon lamp, reducing light loss and ensuring that more light reaches the sample, thus improving light utilization. The xenon lamp's spectral coverage and color temperature are close to sunlight, accurately simulating the solar radiation environment and providing realistic lighting conditions for material aging tests. The design connecting the lamp cover to the test chamber allows light to directly enter the test chamber and act on the sample. The compact structure and good lighting effect ensure the authenticity and effectiveness of the aging test.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting adjustable first and second transfer components, the placement position, spacing and height can be flexibly adjusted according to the shape and volume of the sample, avoiding sample occlusion, ensuring uniform test conditions and improving the consistency of test data; at the same time, the carrier plate can slide along the bracket, which facilitates the placement and removal of the sample, and significantly improves the ease of operation.

[0024] 2. Through the coordinated design of the spray component, ventilation component and lighting component, it can accurately simulate various aging factors in the natural environment such as rain, wind and sunlight, and realize comprehensive and efficient testing of the weather resistance performance of materials; moreover, the spray component adopts a water circulation design, which is energy-saving and environmentally friendly, and the ventilation component can maintain the stability of the environment inside the chamber, further improving the practicality and testing effect of the test chamber.

[0035] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0036] Example 1: This application discloses a flat-panel xenon lamp aging test chamber, referring to...

[0037] Reference Figure 2 , Figure 3 and Figure 4 A bracket 12 is fixedly installed inside the test chamber 11. A carrier plate 13 is placed on the bracket 12. A first transfer assembly 2 for placing samples is installed on the carrier plate 13. The first transfer assembly 2 includes a slide 21. A sliding groove 131 is formed on the carrier plate 13.

A temperature sensor 14 is fixedly installed on the carrier plate 13.

[0038] When placing the sample, drag the carrier plate 13 to slide it out of the housing 1 on the bracket 12, slide the carriage 21 and the locking block 22 into the slide groove 131, adjust the position of the carriage 21 according to the size and shape of the sample, and then slide the locking block 22 on the carriage 21 into the locking groove 132 to complete the positioning of the carriage 21. After the position of the carriage 21 is adjusted, place the sample on the carriage 21 and push the carrier plate 13 into the test chamber 11.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The spray assembly 3 includes a water tank 31, which is fixedly installed on the chassis 1 and located below the test chamber 11. A water pump is installed inside the water tank 31. A water pipe 32 is fixedly installed on the chassis 1. One end of the water pipe 32 is connected to the water pump inside the water tank 31, and the other end extends into the test chamber 11. A nozzle 33 is fixedly installed at the end of the water pipe 32 that extends into the test chamber 11. A return pipe 34 is fixedly installed on the inner bottom wall of the test chamber 11 and is located below the carrier plate 13. The return pipe 34 is connected to the water tank 31.

[0040] During the aging test, water is sprayed onto the sample by nozzle 33 to simulate a rainy day. The tilted test box 11 facilitates water collection and return. The sprayed water flows back into the water tank 31 from the return pipe 34.

[0041] The ventilation assembly 4 includes a fan 41, which is fixedly installed on the housing 1. A ventilation pipe 42 is connected to the fan 41, and the end of the ventilation pipe 42 away from the fan 41 leads into the test chamber 11.

[0042] Reference Figure 5 and Figure 6The illumination component 5 includes a lamp cover 51, which is fixedly mounted on the chassis 1. The bottom of the lamp cover 51 is connected to the top of the test box 11. A xenon lamp 52 is mounted on the lamp cover 51 and is connected to a power supply.

[0043] The xenon lamp 52 has a spectral coverage and color temperature close to sunlight, simulating sunlight irradiation of the sample. A fan 41 blows air into the test chamber 11 to simulate a blowing environment and accelerate sample aging.

[0044] Example 2: Reference Figure 7 , Figure 8 and Figure 9 The difference between this embodiment and Embodiment 1 lies in the method of adjusting the sample placement position. A second transfer assembly 6 is installed on the carrier plate 13. The second transfer assembly 6 includes a fixed plate 61, which is fixedly installed on the carrier plate 13. The fixed plate 61 has four adjustment slots 611, which are dovetail slots. The four adjustment slots 611 are arranged opposite each other in a cross shape. A movable block 62 is slidably installed on the fixed plate 61 through the adjustment slots 611. A fixed rod 63 is fixedly installed on the fixed plate 61. A turntable 64 is rotatably installed on the fixed rod 63. A swing rod 65 is hinged to the turntable 64. The swing rod 65 is L-shaped, and the end of the swing rod 65 away from the turntable 64 is hinged to the movable block 62.

[0045] A plug rod 66 is fixedly installed on the movable block 62. The plug rod 66 has a plurality of first locking holes 661, which are arranged at equal intervals. A plug sleeve 67 is fixedly installed on another movable block 62 opposite to the movable block 62 on which the plug rod 66 is installed. The plug sleeve 67 has a plurality of second locking holes 671, which are arranged at equal intervals. The plug sleeve 67 and the plug rod 66 are slidably connected. A locking rod 68 is inserted into the plug sleeve 67 and the plug rod 66.

[0046] When it is necessary to adjust the spacing between the movable blocks 62, drag two oppositely set movable blocks 62 or rotate the turntable 64. Using the swing rod 65, all the movable blocks 62 can be moved at the same time for quick adjustment. After the movable blocks 62 are adjusted, insert the locking rod 68 into the insert sleeve 67 through the second locking hole 671, and at the same time insert the insert rod 66 through the first locking hole 661 to fix the movable blocks 62. During the test, the movable blocks 62 will move in reverse.

[0047] A telescopic rod 691 is fixedly installed on the movable block 62. A telescopic sleeve 692 is slidably installed on the telescopic rod 691. A lifting plate 693 for placing samples is fixedly installed on the telescopic sleeve 692. A connecting plate 694 is fixedly installed on the fixed rod 63. A support rod 695 is hinged to the connecting plate 694. The end of the support rod 695 away from the connecting plate 694 is hinged to the lifting plate 693.

[0048] When the distance between the movable blocks 62 is adjusted, the movable blocks 62 will be displaced relative to the connecting plate 694. When the movable blocks 62 move, they will drive the support rod 695 to move. Since one end of the support rod 695 is hinged to the connecting plate 694, the support rod 695 will swing around the hinge point with the connecting plate 694, thereby raising and lowering the lifting plate 693, achieving the effect of adjusting the height of the lifting plate 693. This allows the height of the samples to be raised or lowered simultaneously according to the spacing between the samples, thus changing the irradiation situation.

[0049] The implementation principle of this embodiment is as follows: In use, the carrier plate 13 is first pulled out of the test chamber 11. The sample placement spacing is adjusted using the slide 21 of the first transfer component 2. After the sample is placed on the slide 21, it is pushed into the carrier plate 13. Then, the xenon lamp 52 of the illumination component 5, the fan 41 of the ventilation component 4, and the water pump of the spray component 3 are activated. The xenon lamp 52 simulates sunlight, the fan 41 simulates wind and ventilation, and the spray nozzle 33 simulates rain. These three components work together to simulate various aging factors in the natural environment, conducting an artificial accelerated aging test on the sample. The temperature sensor 14 monitors the temperature inside the chamber in real time. Operators can adjust the operating parameters of each component according to testing requirements. Frequent operation is not required during the test, making it highly convenient and ensuring good consistency of test data.

[0050] The turntable and swing arm linkage structure of the second transfer component 6 enables synchronous adjustment of the spacing of the movable block 62. Combined with the locking structure of the insertion rod, sleeve, and locking rod, the stability of the movable block 62's position is ensured. Simultaneously, during the sliding process of the movable block 62, the lifting plate 693 is raised and lowered via the support rod, achieving synchronous adjustment of the sample height and meeting diverse sample placement requirements in different testing scenarios. The combined effect of the spray component 3, ventilation component 4, and lighting component 5 accurately simulates the natural aging environment, improving the accuracy and reliability of test data. Furthermore, the overall operation is simple, significantly enhancing the ease of use and practicality of the test chamber.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
