Description

Technical Field

[0001] This invention relates to the field of xenon lamp testing technology, and more particularly to a xenon lamp life testing device. Background Technology

[0002] Xenon lamps are high-intensity discharge lamps that produce high-brightness, high-color-temperature light through xenon gas discharge. They have advantages such as high luminous efficiency, continuous spectrum, stable light intensity, and long lifespan. They are commonly used in automotive headlights, projectors, stage lighting, and other fields, providing illumination effects close to sunlight and suitable for various lighting needs. During the manufacturing process of xenon lamps, lifespan testing is conducted during production to ensure product quality. A common testing method is the current-voltage method. This method uses current and voltage sensors to monitor the current and voltage of the xenon lamp in real time. Then, through an intelligent control circuit or microcontroller, the frequency of the current and voltage is automatically changed according to a preset testing program, and different number of cycles are set to simulate the operation of the xenon lamp under various working conditions, thereby observing its performance changes. This method can more comprehensively evaluate the stability and lifespan of xenon lamps under different working conditions.

[0003] In existing xenon lamp life testing equipment, the installation and fixing methods of xenon lamps have obvious inconveniences. Traditional equipment mostly uses bolts for fixing, and the testing personnel need to manually tighten multiple bolts to ensure the stable installation of the xenon lamp. This process is not only tedious and time-consuming, but also requires a certain level of skill from the operator. If the bolts are tightened unevenly, it may cause uneven stress on the xenon lamp, affecting the accuracy of the test results.

[0004] Meanwhile, xenon lamps have special requirements during installation, and their glass parts are extremely susceptible to damage from external forces. However, the existing bolt fixing method makes it difficult to avoid contact with the glass during installation, increasing the risk of xenon lamp damage. Once the glass is damaged, it will not only shorten the service life of the xenon lamp, but may also lead to safety hazards during the testing process, affecting the continuity and safety of the testing work. Therefore, a life testing device for xenon lamps is proposed to solve the above problems. Summary of the Invention

The output end of the drive motor passes through the inner side of the top frame and is fixedly connected to the side wall of the threaded rod. The threaded rod is threadedly connected to the inner side wall of the slide plate.

[0010] In the above technical solution, the inner side of the sliding fixture is provided with an arc plate. The bottom two sides of the arc plate are respectively fixedly connected to the top of the test frame with a side plate and a support leg. The side wall of the sliding fixture is provided with a sliding groove adapted to the support leg. A return spring is fixedly connected between the side wall of the sliding fixture and the side wall of the side plate. A positioning frame is longitudinally slidably connected to the fixed frame located on the side wall of the sliding fixture. The positioning frame is located below the limiting plate. A positioning plate is slidably connected to the inner side of the positioning frame. A positioning groove is provided at the top of the test frame relative to the position next to the positioning plate.

It can also automatically release the limit after the test, further improving the convenience of the device. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] In practical use, it was found that the installation and fixing method of xenon lamps has obvious inconveniences. Traditional equipment mostly uses bolts for fixing, and the testing personnel need to manually tighten multiple bolts to ensure the stable installation of xenon lamps. This process is not only tedious and time-consuming, but also requires a certain level of skill from the operator. If the bolt tightening force is uneven, it may cause uneven force on the xenon lamp, affecting the accuracy of the test results. In order to solve the above problems, the following structure was invented.

[0022] like Figures 1-9The device shown is a xenon lamp life testing device, including a test control cabinet 1 and a test frame 2. The test control cabinet 1 and the test frame 2 are electrically connected. The test control cabinet 1 uses automated equipment to change the current, voltage, frequency, and cycle number of the xenon lamp according to a preset program to simulate different working conditions and accelerate its aging. The xenon lamp is run under different loads, and the changes in performance indicators are monitored to evaluate the stability and durability of the xenon lamp, thereby quickly determining its service life. Several fixed clamps 3 are fixedly connected to the test frame 2. Sliding clamps 4 are slidably connected to the test frame 2 relative to the rear of the fixed clamps 3. The top of each fixed clamp 3 and sliding clamp 4 has a pair of circular holes through which a sliding clamp is inserted. The test frame 2 is equipped with a telescopic rod 5, and an upper clamp 6 is fixedly connected between the top ends of the telescopic rods 5. Side rods 7 are fixedly connected to the side walls of the upper clamps 6. Side grooves are opened on the side walls of the side rods 7. Limiting blocks 8 are slidably connected in the side grooves, and the bottom ends of the limiting blocks 8 are inclined. Fixed frames 9 are fixedly connected to the side walls of the fixed clamps 3 and the sliding clamps 4. Limiting plates 10 are slidably connected to the inside of the fixed frames 9. Several upper right-angled blocks 11 with inclined surfaces are fixedly connected at equal intervals on the side walls of the limiting plates 10. Release rods 12 are fixedly connected to the side walls of the limiting plates 10, and the side walls of the release rods 12 penetrate the outer wall of the fixed frames 9. The test frame 2 is equipped with a disassembly and assembly mechanism for pushing the upper clamps 6 down and squeezing the release rods 12. Three upper springs 13 are fixedly connected between the inner side of the fixed frame 9 and the side wall of the limiting plate 10. A lifting spring 14 is fixedly connected between the top of the test frame 2 and the bottom of the telescopic rod 5. A lower spring 15 is fixedly connected between the inner side of the side groove and the side wall of the limiting block 8. The sliding clamp 4 is electrically connected to the negative terminal of the test power supply. It should be noted that the part of the sliding clamp 4 that contacts the negative terminal of the xenon lamp must ensure good conductivity. It is usually made of metal materials with excellent conductivity (such as copper, aluminum, etc.). When designing the sliding clamp 4, the relative position and shape of the clamp and the xenon lamp need to be considered to ensure that the clamp will not accidentally contact other parts of the xenon lamp. At the same time, insulation protection measures can be added in the area around the contact between the sliding clamp 4 and the xenon lamp, such as using insulating tape, insulating sleeve, etc., to further reduce the risk of short circuit. The disassembly and assembly mechanism includes an upper electric telescopic cylinder 16 and a lower electric telescopic cylinder 17. A top frame 18 is fixedly connected to the inside of the test frame 2. A sliding plate 21 is slidably connected inside the top frame 18. Both the upper electric telescopic cylinder 16 and the lower electric telescopic cylinder 17 are fixedly connected to the top of the sliding plate 21. The output end of the upper electric telescopic cylinder 16 passes through the bottom end of the sliding plate 21 and is fixedly connected to an L-shaped plate 22. The output end of the lower electric telescopic cylinder 17 passes through the bottom end of the sliding plate 21 and is fixedly connected to a tapered plate 23 with inclined surfaces on both sides. A threaded rod 19 is rotatably connected to the inner side of the top frame 18, and a drive motor 20 is fixedly connected to the side wall of the test frame 2. The output end of the drive motor 20 passes through the inner side of the top frame 18 and is fixedly connected to the side wall of the threaded rod 19. The threaded rod 19 is threadedly connected to the inner side wall of the slide plate 21. During the life testing of xenon lamps, the xenon lamps to be tested are first placed on the fixed clamp 3 and the sliding clamp 4 in sequence. Then, the drive motor 20 is started to rotate the threaded rod 19, which in turn moves the threaded sliding plate 21. At the same time, the upper electric telescopic cylinder 16 and the lower electric telescopic cylinder 17 are moved, and the L-shaped plate 22 is moved above the fixed clamp 3 and the sliding clamp 4. Then, the upper electric telescopic cylinder 16 is started to move the L-shaped plate 22 downward, which pushes the upper clamp 6 downward. At the same time, the telescopic rod 5 slides in the round hole and gradually compresses the lifting spring 14. Then, the side rod 7 is inserted into the fixed frame 9. When the limiting block 8 moves above the upper right-angle block 11, the inclined surface of the limiting block 8 will be squeezed by the inclined surface of the upper right-angle block 11, which will push the limiting block 8 into the side groove and compress the lower spring 15. Subsequently, when the limiting block 8 moves away from the upper right-angle block 11, the pressure on the limiting block 8 is released. Then, under the elastic force of the lower spring 15, the limiting block 8 is pushed back to its original position and locked at the bottom of the upper right-angle block 11. This process is repeated until the upper clamp 6 completely clamps both ends of the xenon lamp within the fixed clamp 3 and the sliding clamp 4, thereby achieving clamping and fixing of the xenon lamp. At the same time, the limiting block 8 is locked below the corresponding upper right-angle block 11, preventing the upper clamp 6 from moving downward. Meanwhile, the sliding clamp 4 is connected to the negative power supply of the test control cabinet 1. Therefore, by locking, it can be ensured that the negative terminal of the xenon lamp is connected to the negative terminal of the test control cabinet 1. The electrical connection between them is then controlled to reset the electric telescopic cylinder 16, and then the drive motor 20 is controlled to continue to start, driving the L-shaped plate 22 to move above the next upper clamp 6. The above operation is repeated to clamp multiple xenon lamps in sequence. After all xenon lamps are fixed, the test control cabinet 1 is operated to change the current, voltage, frequency and number of cycles of the xenon lamps according to the preset program to simulate different working conditions, accelerate their aging, run the xenon lamps under different loads, monitor the changes in performance indicators, and thus evaluate the stability and durability of the xenon lamps, thereby quickly determining their service life. After the test is completed, the lower electric telescopic cylinder 17 can be started to drive the conical plate 23 to move down. The conical plate 23 then moves above the two release rods 12. As the conical plate 23 gradually moves down, it will squeeze the release rods 12 to slide to both sides. At the same time, it will drive the limiting plate 10 and the upper right-angle block 11 to slide to both sides within the fixed frame 9 and gradually compress the upper spring 13. This will cause the upper right-angle block 11 to move out of the limiting block 8, releasing the position restriction on the limiting block 8. Then, under the elastic force of the lifting spring 14, the telescopic rod 5 is pushed to reset, thereby automatically releasing the locking fixation of the xenon lamp. Then, the lower electric telescopic cylinder 17 is reset, and the drive motor 20 is controlled to move the electric telescopic cylinder 17 to the top of the subsequent release rods 12 to release them.

[0023] In summary, through the design of the above structure, the xenon lamp can be automatically locked and fixed by simply placing it on the fixed clamp 3 and the sliding clamp 4. Furthermore, the sliding clamp 4 is electrically connected to the negative terminal of the test power supply, so that when the negative terminal of the xenon lamp is locked, it can automatically connect to the negative terminal of the test power supply. This eliminates the need for testing personnel to lock each lamp one by one with tools, greatly improving the convenience of the device. Moreover, the locking limit of the xenon lamp can be automatically released after the test, and the disassembly and assembly mechanism can move laterally, allowing for automatic disassembly and assembly of multiple xenon lamps on the test rack 2.

[0024] Based on the above embodiments, it was found during use that if the positions of the fixed clamp 3 and the sliding clamp 4 are fixed during the placement of the xenon lamp, the xenon lamp needs to be tilted back and forth during placement, which inevitably leads to collisions with the glass of the xenon lamp and damage. In order to solve the above problems, the above structure has been further improved.

[0025] The inner side of the sliding clamp 4 is provided with an arc plate 24. The bottom two sides of the arc plate 24 are fixedly connected to the top of the test frame 2, respectively, with a side plate 40 and a support leg 25. The side wall of the sliding clamp 4 is provided with a sliding groove that matches the support leg 25. The sliding groove is provided to avoid hindering the movement of the sliding clamp 4. A return spring 26 is fixedly connected between the side wall of the sliding clamp 4 and the side wall of the side plate 40. A positioning frame 27 is longitudinally slidably connected to the inner side of the fixed frame 9 located on the side wall of the sliding clamp 4. The positioning frame 27 is located below the limiting plate 10. A positioning plate 28 is slidably connected to the inner side of the positioning frame 27. A positioning groove 29 is provided at the top of the test frame 2 relative to the position next to the positioning plate 28. A positioning spring 30 is fixedly connected between the top of the inner side of the positioning frame 27 and the top of the positioning plate 28. The bottom end of the limiting plate 10 is fixedly connected to a lower right-angle block 31 with an inclined surface. The inner side of the fixing frame 9 is fixedly connected to an upper plate 32. A pair of release springs 33 are fixedly connected between the bottom end of the upper plate 32 and the top end of the positioning frame 27. When the limiting plate 10 is in the initial state, the release springs 33 are in the stretched state because the pressing block 34 on the positioning frame 27 is pressed by the lower right-angle block 31. The top end of the positioning frame 27 is fixedly connected to the pressing block 34, and the top end of the pressing block 34 is inclined. The inclined surface of the pressing block 34 is in contact with the inclined surface of the lower right-angle block 31. A side electric telescopic cylinder 35 is fixedly connected to the side wall of the L-shaped plate 22, and the output end of the side electric telescopic cylinder 35 is set through the inner side of the L-shaped plate 22. When the xenon lamp is placed on the fixed clamp 3 and the sliding clamp 4, the sliding clamp 4 is in a backward state. When the control drive motor 20 moves the L-shaped plate 22 above the upper clamp 6, the side electric telescopic cylinder 35 is started first. The output end of the side electric telescopic cylinder 35 pushes the upper clamp 6 to move. At the same time, the telescopic rod 5 drives the sliding clamp 4 to slide on the test frame 2. At the same time, the return spring 26 is stretched. Then, one of the support legs 25 moves into the slide groove of the sliding clamp 4. At the same time, the negative electrode of the xenon lamp moves completely onto the sliding clamp 4. It should be noted that since the negative electrode of the xenon lamp is placed on the arc plate 24, after the sliding clamp 4 is completely moved into place, the arc plate 24 is connected to the conductive part on the sliding clamp 4. Therefore, the sliding clamp 4 is directly connected to the negative electrode of the xenon lamp through the arc plate 24. At the same time, a moving groove needs to be opened on the test frame 2 to ensure the normal movement of the power cord on the sliding clamp 4 and avoid obstruction. Then, when the side electric telescopic cylinder 35 pushes the sliding clamp 4 into place, the positioning plate 28 will move above the positioning groove 29, and then under the elastic force of the positioning spring 30, the positioning plate 28 will be pushed into the corresponding positioning groove 29 to restrict the position of the sliding clamp 4. Finally, the upper electric telescopic cylinder 16 can be controlled to start clamping the xenon lamp. Finally, after the test is completed, as the lower electric telescopic cylinder 17 drives the limiting plate 10 to move to both sides, it will drive the lower right-angle block 31 to move, thereby gradually releasing the pressure on the squeezing block 34. Then, under the elastic force of the release spring 33, the positioning frame 27 and the squeezing block 34 are pulled up, and the positioning plate 28 is pulled out from the positioning groove 29, thereby automatically releasing the position restriction of the fixed frame 9. Then, under the elastic force of the reset spring 26, the sliding clamp 4 is pulled back to its original position. Then, the release rod 12 will move out from the conical plate 23, releasing the pressure on the release rod 12. Subsequently, under the elastic force of the upper spring 13, the reset is pushed, and at the same time, the lower right-angle block 31 pushes the squeezing block 34 down, and drives the positioning frame 27 down. Since the positioning plate 28 is located on the test frame 2 at this time, it cannot move down, so the positioning spring 30 will be compressed.

[0026] In summary, the above structural design allows the sliding clamp 4 to be in a rearward position when placing the xenon lamp. Only one end of the xenon lamp needs to be inserted into the fixed clamp 3, and the other end can be placed flat on the arc plate 24. There is no need to tilt the xenon lamp back and forth on the clamp, which reduces the possibility of damaging the xenon lamp and improves the convenience of the testing process.

[0027] Based on the above embodiments, it was found during use that after the xenon lamp is installed, the positive electrode connection piece of the xenon lamp also needs to be tightened and fixed, which is quite cumbersome. To solve the above problem, the above structure has been further improved.

[0028] A positive electrode plug 36 is fixedly connected to the top of the test fixture 2 relative to the side of the fixed clamp 3. The positive electrode plug 36 is electrically connected to the positive electrode of the test power supply. A locking plate 37 is slidably connected to the top of the test fixture 2 relative to the side wall of the fixed clamp 3. A circular groove is opened through the side wall of the locking plate 37. A pair of locking springs 38 are fixedly connected between the side wall of the locking plate 37 and the side wall of the fixed clamp 3. The top of the locking plate 37 is inclined. A right-angled extrusion block 39 with an inclined surface is fixedly connected to the side wall of the upper clamp 6 located above the fixed clamp 3.

[0029] Before the upper clamp 6 moves down to clamp the xenon lamp, driven by the upper electric telescopic cylinder 16, the positive electrode connecting piece of the xenon lamp is first inserted into the positive electrode plug 36. This will cause the pressing right-angle block 39 on the upper clamp 6 to move down. Then, when the inclined surface of the pressing right-angle block 39 moves to the inclined surface at the top of the locking plate 37, since the locking plate 37 can slide laterally, the inclined surface of the pressing right-angle block 39 will push the locking plate 37 to move laterally during the gradual downward movement of the pressing right-angle block 39. At the same time, the locking spring 38 is stretched, and then the circular groove on the locking plate 37 passes through the positive electrode plug 36, pressing the positive electrode connecting piece of the xenon lamp onto the positive electrode plug 36, ensuring the connection between the xenon lamp and the positive electrode of the test control cabinet 1. Finally, after the test is completed, when the pressing right-angle block 39 is removed, the locking plate 37 will be reset by the elastic force of the locking spring 38, automatically releasing the locking of the positive electrode connecting piece.

[0030] In summary, with the design of the above structure, after placing the xenon lamp, simply insert the positive electrode connecting piece into the positive electrode plug 36, and during the subsequent locking process, the positive electrode connecting piece will be tightly locked onto the positive electrode plug 36, realizing fully automatic connection of the positive and negative power supplies of the xenon lamp. It can also automatically release the limit after the test, further improving the convenience of the device.
