Description

Technical Field

[0001] This utility model relates to the field of UV lamp testing technology, and more specifically, to a UV lamp life testing device. Background Technology

[0002] UV lamps are widely used in curing, sterilization, water treatment and other fields. Their luminous intensity decays over time. Therefore, during the production of UV lamps, it is necessary to test their initial light decay characteristics and estimate their service life to ensure that the products leaving the factory meet quality requirements and to prevent prematurely failed products from entering the market.

[0003] Most existing testing devices only support single-lamp testing, which cannot meet the needs of industrial batch testing. Manual lamp replacement is time-consuming and inefficient. The lack of effective sealing design makes UV light leakage harmful to operators and can easily affect the lifespan of the testing equipment. Frequent sensor replacement is required, which is costly. Furthermore, it is difficult to effectively control the temperature of the UV lamp during testing. Poor heat dissipation leads to increased lamp temperature, accelerating aging and affecting the accuracy of the test data. It is also difficult to understand the lifespan of the UV lamp under different ambient temperatures, making it impossible to ensure the comprehensiveness of the lifespan data and affecting the test results.

[0017] Furthermore, the side wall of the testing chamber is equipped with several activated carbon filter covers that correspond to several working chambers and are used to shield several exhaust channels. The side wall of the testing chamber is symmetrically and fixedly connected with flow guide covers corresponding to several activated carbon filter covers.

[0021] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0022] 1. This UV lamp life testing device, through several working chambers, can install multiple UV lamps. It works in conjunction with a vertically moving testing frame driven by two control screws in the testing section, and several UV sensors on both sides of the testing frame to sequentially test multiple UV lamps. When installing a single UV lamp, the remaining UV lamps can be tested simultaneously, ensuring testing efficiency and facilitating data comparison of UV lamps in different working chambers to understand the differences in the lifespan of UV lamps in different batches, thus facilitating production improvements.

[0023] 2. This UV lamp life testing device, through several sealing sections, can close and open several testing slots. The movement of the sealing plate in the sealing section is synchronized with the rotation of the assembly section. When testing the UV lamp in the corresponding working chamber, the sealing plate opens the testing slot, and the UV lamp tube rotates through the assembly section to align with the testing slot, allowing light to enter the testing chamber for testing. When the UV lamp is not being tested, the sealing plate closes the testing slot, and the UV lamp tube rotates through the assembly section to prevent irradiation of the testing slot, thereby avoiding external interference or ultraviolet leakage, preventing UV light leakage from harming operators, and preventing the lifespan of several UV sensors in the testing section from being affected. This eliminates the need for frequent replacement of UV sensors, reducing costs.

[0024] 3. This UV lamp life testing device, through its heat dissipation section, can effectively dissipate heat from the testing chamber and several working chambers. The heat dissipation section, including the mounting cover, mounting frame, and mounting plate, has heat dissipation grooves that directly surround the UV lamp tube. Heat is conducted to the heat dissipation grooves through two lamp holders, forming a combined heat dissipation of contact, conduction, and convection. This ensures effective heat dissipation for the UV lamp, preventing excessive temperature from accelerating UV lamp aging and affecting test data. Simultaneously, under the control of the enclosed section, the airflow of the air inlet and outlet grooves on both sides of a single working chamber can be adjusted to change the heat dissipation effect. The temperature in several working chambers can be controlled by spacing, facilitating the testing and understanding of UV lamp life under different ambient temperatures and improving the comprehensiveness of UV lamp life testing.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0037] like Figure 1-8 As shown, a UV lamp life testing device includes: a testing box 1, a control panel 2 installed at the front end of the testing box 1, a plurality of working chambers 3 evenly spaced at the front and rear ends of the testing box 1, and a testing chamber 4 and a flow-diverting chamber 5 arranged in the middle of the testing box 1.

[0038] The front and rear sides of the detection box 1 are equipped with several sealing doors 6 for sealing several working chambers 3 respectively. The detection box 1 is provided with several detection slots 7 for connecting several working chambers 3 and detection chambers 4.

[0039] The detection unit 8 is disposed in the detection cavity 4 and is used to move vertically within the detection cavity 4 to align with a plurality of detection slots 7.

[0040] Assembly part 9, a plurality of the assembly parts 9 are rotatably installed in a plurality of the working cavities 3;

[0041] The sealing part 10 is installed in the working chamber 3, and the sealing and unfolding of the detection groove 7 are performed synchronously when the assembly part 9 rotates.

[0042] Heat dissipation unit 11 is installed on the detection box 1 and is used to connect the detection chamber 4, the diversion chamber 5 and the plurality of working chambers 3 to each other and to allow airflow interaction with the external environment.

[0043] In use, the operator opens the closed door 6. Under the control of the sealing section 10, the opening of the assembly cover 17 in the assembly section 9 faces the closed door 6 directly. This allows the operator to quickly assemble the UV lamps in the assembly section 9. Furthermore, the two assembly brackets 18 in the assembly cover 17 can be adjusted to easily adjust the distance between the two lamp holders 24. With the elasticity of the return spring 23, it facilitates the assembly of UV lamps of different lengths, ensuring the practicality of the device. After closing the closed door 6, the temperature sensor 42 begins monitoring the environment of the working chamber 3. Since the device has multiple detection chambers 4, multiple... The UV lamps are tested synchronously, and while testing a single UV lamp, the UV lamps in the remaining working chambers 3 can be assembled and replaced without affecting the normal testing of the remaining UV lamps, ensuring the testing efficiency of the UV lamps. During testing, the control panel 2 activates the control device. In the enclosed part 10, the first motor 14 drives the assembly cover 17 in the single working chamber 3 to rotate through the first bevel gear set 15. Under the rotation of the assembly cover 17, the two control gears 16 mesh with the control rack 13 to drive the enclosed plate 12 to open the detection slot 7, so that the rotated UV lamp is aligned with the detection chamber 4. At the same time, the detection part 8 works, and the first... Two motors 37, in cooperation with a toothed belt and two transmission gears 40, drive two control screws 33, causing the detection frame 34 to move vertically along the guide rail 35 to the open detection slot 7. Several UV sensors 39 then perform a comprehensive scan of the UV lamps. Since UV sensors 39 are installed on both sides of the detection frame 34, the UV lamps in both working chambers 3 can be detected simultaneously. After the detection is completed, the sealing plate 12 in the sealing section 10 automatically closes the detection slot 7, and the UV sensors 39 on the detection frame 34 move to detect the remaining working chambers 3. The movement of the sealing plate 12 in the sealing section 10 will interact with the... The assembly part 9 rotates synchronously. When the UV lamp in the corresponding working chamber 3 is being tested, the sealing plate 12 opens the detection slot 7, and the UV lamp tube rotates through the assembly part 9 to align with the detection slot 7, allowing light to enter the detection chamber 4 for testing by the detection part 8. When the UV lamp is not being tested, the sealing plate 12 closes the detection slot 7, and the UV lamp tube rotates through the assembly part 9 to avoid irradiating the detection slot 7, thereby preventing external interference or ultraviolet leakage, preventing UV light leakage from harming the operator, and preventing the lifespan of several UV sensors 39 in the detection part 8 from being affected. This eliminates the need for frequent replacement of UV sensors 39 and effectively reduces operating costs.Meanwhile, during the testing of UV lamps in several working chambers 3, under the control of the heat dissipation unit 11, heat dissipation can be effectively carried out in the testing chamber 4 and several working chambers 3. The heat dissipation grooves 30 on the assembly cover 17, assembly frame 18 and assembly plate 22 in the heat dissipation unit 11 directly surround the UV lamp tube, and conduct heat to the heat dissipation grooves 30 through the two lamp holders 24, forming a combination of contact heat conduction and convection heat conduction to ensure the heat dissipation effect of the UV lamp, avoid excessive temperature to accelerate the aging of the UV lamp, and affect the test data. At the same time, in some testing methods, the temperature in several working chambers 3 can be kept relatively consistent, providing a stable and consistent testing environment. This allows for effective comparison of the test data of UV lamps in different working chambers 3, understanding the lifespan of different batches of UV lamps in different working chambers 3, and adjusting the production method based on the data. Furthermore, when necessary, under the control of the sealing unit 10, the airflow of the air inlet grooves 27 and exhaust grooves 28 on both sides of a single working chamber 3 can be adjusted to change the heat dissipation effect. The temperature in several working chambers 3 can be controlled by spacing, which facilitates the testing and understanding of the UV lamp lifespan under different ambient temperatures and improves the comprehensiveness of the UV lamp lifespan test data. ;

[0044] Optionally, the enclosed part 10 includes a sealing plate 12 that is slidably mounted in the working chamber 3 and corresponds to one of the detection slots 7; two control racks 13 that are symmetrically fixed on both sides of the sealing plate 12; a first motor 14 that is fixed in the diversion chamber 5; a first bevel gear set 15 that is fixed at the output end of the first motor 14; and two control gears 16 that are symmetrically fixed at both ends of the assembly part 9 and abut against the inner wall of the working chamber 3.

[0045] The two control gears 16 respectively mesh with the two control racks 13;

[0046] The output end of the first motor 14 is connected to the assembly part 9 via the first bevel gear set 15;

[0047] When the UV lamp in a working chamber 3 needs to be inspected by the inspection unit 8, the first motor 14 starts and transmits power to the assembly unit 9 through the first bevel gear set 15 to control the rotation of the assembly unit. When the assembly unit 9 rotates, the control gears 16 at both ends rotate synchronously. The control gears 16 mesh with the control racks 13 fixed on both sides of the sealing plate 12. Under the rotation of the two control gears 16, the two control racks 13 drive the sealing plate 12 to slide along the inner wall of the working chamber 3, realizing the opening and closing of the inspection chamber 4; the movement and assembly of the sealing plate 12... The rotation of the assembly 9 is synchronized. During testing, the sealing plate 12 opens the testing slot 7, and the UV lamp is rotated to align with the testing slot 7, allowing light to enter the testing chamber 4. When not testing, the sealing plate 12 closes the testing slot 7, preventing the UV lamp from directly facing the dust collection tank and avoiding external interference or ultraviolet leakage. Through the meshing transmission of the control gear 16 and the control rack 13, the movement of the sealing plate 12 is strictly synchronized with the rotation of the lamp position, ensuring stable control and avoiding misoperation. When the power is off, the sealing plate 12 remains in its current position to prevent accidental opening.

[0048] Optionally, the assembly part 9 includes an assembly cover 17 rotatably connected to the working cavity 3; two assembly frames 18 symmetrically slidably installed in the assembly cover 17; two positioning bolts 19 respectively threaded onto the two assembly frames 18; a plurality of positioning grooves 20 equally spaced in the assembly cover 17 and adapted to the two positioning bolts 19; a plurality of sliding rods 21 fixed in one of the assembly frames 18; an assembly plate 22 slidably connected to one of the assembly frames 18 through the plurality of sliding rods 21; a return spring 23 with its two ends fixed to the assembly plate 22 and one of the assembly frames 18 respectively; and two lamp holders 24 respectively installed on the assembly plate 22 and the other assembly frame 18.

[0049] The first motor 14 is connected to the assembly cover 17 via the first bevel gear set 15;

[0050] In use, the positioning bolts 19 on the two mounting brackets 18 can be rotated to loosen the restriction on the two mounting brackets 18. At this time, the two mounting brackets 18 can be slid to a suitable position to match the length of the UV lamp. Then, the two positioning bolts 19 are tightened so that they are engaged in the corresponding positioning grooves 20 inside the mounting cover 17 to fix the two mounting brackets 18. Then, the two ends of the UV lamp to be tested are inserted into the two lamp holders 24 respectively. One end is elastically pressed by the return spring 23 and several sliding rods 21. The spring force ensures that the electrodes at both ends of the UV lamp are in close contact with the two lamp holders 24 to avoid poor contact and detection errors. This facilitates the rapid testing of UV lamps of different lengths. The assembly cover 17 is easy to install and quick to remove after UV lamp testing, making it highly practical. In use, the assembly cover 17 isolates the heat radiation from the UV lamp in most directions, reducing damage to the working chamber 3. When the sealing part 10 is working, the assembly cover 17 can be driven to rotate so that its unfolded direction faces the sealing door 6, facilitating the installation of the UV lamp. It can also be controlled to ensure the unfolded direction of the assembly cover 17 faces the testing slot 7. As the assembly cover 17 rotates, the sealing part 10 releases the seal on the testing slot 7, facilitating effective testing of the UV lamp by the testing part 8 and preventing UV lamp irradiation of the testing slot 7 during non-testing phases.

[0051] Optionally, the heat dissipation unit 11 includes a plurality of cooling fans 25 evenly spaced on one side of the detection box 1 and corresponding to the detection cavity 4; a plurality of connecting slots 26 for connecting the detection cavity 4 and the diversion cavity 5; a plurality of air inlet slots 27 for connecting the diversion cavity 5 and a plurality of working cavities 3; a plurality of exhaust slots 28 formed on the detection box 1 and corresponding to the plurality of air inlet slots 27; a plurality of ventilation slots 29 formed on a plurality of control gears 16 and corresponding to the plurality of exhaust slots 28 and air inlet slots 27; and a plurality of heat dissipation slots 30 formed on a plurality of assembly covers 17, assembly frames 18 and assembly plates 22 and corresponding to the plurality of exhaust slots 28 and air inlet slots 27.

[0052] During operation, several cooling fans 25 draw external air into the detection chamber 4, removing heat from the chamber. The air then flows through several connecting channels 26 into the diversion chamber 5, and then through several air inlet channels 27 into several working chambers 3. After passing through several ventilation channels 29 and heat dissipation channels 30, the air carries away heat from the UV lamps during operation. Finally, it is exhausted through several exhaust channels 28, effectively controlling the temperature in the working chambers 3 and preventing temperature accumulation that could affect the UV lamp detection data. Meanwhile, the assembly cover 17, assembly frame 18, and assembly plate 22... The heat dissipation groove 30 directly surrounds the UV lamp tube, and heat is conducted to the heat dissipation groove 30 through the two lamp holders 24, forming a dual heat dissipation of contact heat conduction and convection heat conduction to ensure the heat dissipation effect of the UV lamp; while the control gear 16 rotates in the working chambers 3, the ventilation groove 29 on it will periodically align with the air inlet groove 27 and the exhaust groove 28, or be misaligned with the air inlet groove 27 and the exhaust groove 28, so as to facilitate the control of the air flow of the air inlet groove 27 and the exhaust groove 28, thereby indirectly controlling the temperature in the working chambers 3, and facilitating the detection of the UV lamp's lifespan under different temperature conditions.

[0053] Optionally, the side wall of the testing chamber 1 is equipped with several activated carbon filter covers 31, each corresponding to a number of working chambers 3 and used to shield the number of exhaust slots 28. The side wall of the testing chamber 1 is symmetrically and fixedly connected with flow guide covers 32 corresponding to the number of activated carbon filter covers 31. The activated carbon filter covers 31 adsorb harmful gases generated when the UV lamp is working or when it is damaged, thus preventing the working environment from deteriorating. The flow guide covers 32 can realize directional exhaust, preventing the hot airflow discharged from the heat dissipation part 11 from being re-inhaled, thus ensuring the heat dissipation effect of the heat dissipation part 11.

[0054] Optionally, the detection unit 8 includes two control screws 33 symmetrically rotatably installed in the detection cavity 4; a detection frame 34 whose two ends are respectively threaded to the two control screws 33 and whose two sides abut against the inner wall of the detection cavity 4; two guide rails 35 symmetrically fixed in the detection cavity 4, two guide blocks 36 respectively fixed to the two ends of the detection frame 34 and slidably mounted on the two guide rails 35; a second motor 37 installed in the diversion cavity 5; a second bevel gear set 38 fixed between the output end of the second motor 37 and one of the control screws 33; a plurality of UV sensors 39 symmetrically installed on both sides of the detection frame 34; two transmission gears 40 respectively fixed to the top of the two control screws 33; and a transmission toothed belt 41 meshing and sleeved on the two transmission gears 40.

[0055] The second motor 37 is connected to one of the control screws 33 via the second bevel gear set 38. In use, the second motor 37 operates, driving one of the control screws 33 to rotate via the second bevel gear set 38. Under the meshing transmission of the transmission belt 41 and the two transmission gears 40, the other control screw 33 rotates synchronously. This causes the threaded transmission detection frame 34 to move vertically within the detection chamber 4, facilitating alignment and blocking of the detection slots 7 at the corresponding working chamber 3. This allows several UV sensors 39 to detect ultraviolet radiation data at different positions of the UV lamp through the detection slots 7, determining the radiation data at different positions after prolonged use of the UV lamp, identifying the failure time and location of the UV lamp, and transmitting the data through the detection frame 34. The vertical reciprocating movement enables long-term cyclic testing to establish multiple UV lamp attenuation curve models, ensuring the accuracy of lifespan data. UV sensors 39 are installed at equal intervals on both sides of the testing frame 34, allowing simultaneous testing of UV lamps in two opposing working chambers 3, resulting in high testing efficiency. Furthermore, both sides of the testing frame 34 abut against the inner wall of the testing chamber 4, ensuring a sealed effect for the corresponding tests, isolating ambient light interference, and ensuring that the UV sensors 39 only receive UV lamp radiation signals, preventing light leakage into the testing chamber 4 during testing and thus avoiding interference with the testing data. During the vertical movement of the testing frame 34, two guide blocks 36 move on two guide rails 35 respectively, limiting the horizontal movement of the testing frame 34 and ensuring the stability of its vertical movement.

[0056] Optionally, temperature sensors 42 are installed in each of the working chambers 3. The second motor 37, the temperature sensors 42, the cooling fans 25, and the first motors 14 are all electrically connected to the control panel 2. The temperature sensors 42 monitor the temperature in each of the working chambers 3 in real time and transmit the temperature data to the control panel. The control panel 2 can control the sealing part 10 to move slightly, so that the air inlet slots 27 and exhaust slots 28 of the two working chambers 3 can be partially closed to change the heat dissipation effect and indirectly adjust the temperature in different working chambers 3. This facilitates the detection of the lifespan of UV lamps under different temperature conditions and improves the accuracy of the detection data. The speed of the cooling fans 25 can also be adjusted to change the airflow of the cooling system. At the same time, it is convenient to preset the detection program so that the detection unit 8 can automatically detect the UV lamps in the working chambers 3 in a cyclic manner, reducing manual intervention.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
