Description

Technical Field

[0001] The present invention relates to the technical field of capacitor aging testing, and particularly to an aging vibration testing device. Background Art

[0002] Since the birth of aluminum electrolytic capacitors in the early 20th century, they have been widely used in radio and electronic devices due to their advantages such as high capacitance density, low equivalent series resistance, and low leakage current. However, the lifespan of aluminum electrolytic capacitors is relatively short, and there is a risk of electrolyte leakage, which has prompted the need for aging testing technology. To ensure the quality and reliability of capacitors, manufacturers and researchers have developed aging vibration testing devices. This device simulates the working environment of aluminum electrolytic capacitors during actual use by performing vibration and aging tests on them, thereby evaluating their performance and lifespan and ensuring the stable operation of capacitors in electronic devices. With the continuous progress of technology, the performance and lifespan of aluminum electrolytic capacitors are also constantly improving, and aging vibration testing devices are also constantly updated and improved.

[0003] After retrieval, the patent with Chinese patent number CN221826987U discloses an aluminum electrolytic capacitor aging testing device, which includes a test chamber for testing, a support base fixedly arranged at the bottom of the test chamber, and a display screen fixedly arranged at the top of the test chamber. A cavity is provided inside the test chamber, and a driving motor is fixedly arranged on the rear surface inside the test chamber. The output end of the driving motor located at the front end is fixedly provided with a turntable, and a guide groove is provided on the front surface of the turntable. Two clamping rods are arranged at the middle position inside the guide groove. This aluminum electrolytic capacitor aging testing device, by setting the driving motor, turntable, clamping rods, and clamping springs, enables the device to drive the product to rotate during use, thereby performing multi-directional testing, avoiding omissions, ensuring the accuracy rate of product testing, bringing convenience to users, improving the practicability of the device, meeting the usage requirements of users. Compared with the prior art, the patent with Chinese patent number CN221826987U solves the problem that when the aluminum electrolytic capacitor aging testing device is in use, it cannot perform multi-sided testing, resulting in easy omission during testing by users, bringing inconvenience to users, and not meeting the usage needs of users.

[0004] However, during the actual use of the above device, when performing vibration testing on aluminum electrolytic capacitors, it is necessary for personnel to manually fix the capacitors to the vibrator for operation. This not only has poor efficiency but also high-intensity vibration is likely to cause the capacitors to loosen. Moreover, different specifications of capacitors require the replacement of different-sized mounting seats, which is inconvenient to use. Therefore, an aging vibration testing device is proposed. Summary of the Invention

[0005] The object of the present invention is to solve the problems in the prior art that when an aluminum electrolytic capacitor is subjected to a vibration test, it is necessary for personnel to manually fix the capacitor to a vibrating machine for operation, resulting in poor efficiency. At the same time, high-intensity vibration is likely to cause the capacitor to loosen, and different specifications of capacitors require the replacement of different-sized mounting seats, which is inconvenient to use. Therefore, an aging vibration test device is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An aging vibration test device includes a test box. A transmission mechanism is arranged inside the test box. A vibration mechanism is fixedly connected to the front end of the transmission mechanism. A clamping mechanism is fixedly connected to the upper part of the vibration mechanism. The clamping mechanism includes a clamping housing fixedly connected to the upper part of the vibration mechanism. A first motor is arranged on the upper part of the clamping housing. A fifth gear is arranged at the output end of the first motor. A seventh gear and a sixth gear are meshed and connected on both sides of the fifth gear. An eighth gear is meshed and connected to the side of the sixth gear away from the fifth gear. The seventh gear and the eighth gear are meshed and connected with a clamping member. By driving the fifth gear to rotate through the first motor, the rotation of the fifth gear drives the seventh gear and the eighth gear to rotate, and then drives the clamping members on both sides to move and close, clamping and fixing aluminum electrolytic capacitors of different specifications;

[0008] The vibration mechanism includes a vibration frame fixedly connected to the front part of the transmission mechanism. A second motor is arranged on one side of the vibration frame. A third gear is arranged at the output end of the second motor. A fourth gear is meshed and connected above the third gear. The fourth gear is rotatably connected to the vibration frame. Eccentric shafts are rotatably connected to both sides of the fourth gear. A vibration table is rotatably connected to the side of the eccentric shaft away from the fourth gear. The vibration table is slidably connected to the vibration frame. A clamping housing is fixedly connected to the upper part of the vibration table. By driving the eccentric shaft to rotate through the second motor, the rotation of the eccentric shaft drives the vibration table to vibrate up and down, and then drives the fixedly connected clamping mechanism and the capacitor clamped by the clamping mechanism to vibrate. An observation window is arranged on one side of the test box, and the material of the observation window is transparent.

[0009] The above technical solution further includes:

[0010] An inlet is arranged at the front end of the test box, and the clamping mechanism passes through the inlet.

[0011] A temperature control device is arranged inside the test box to adjust the temperature inside the test box through the temperature control device.

[0012] A flow equalizing mechanism is arranged on the upper part of the test box, and the flow equalizing mechanism drives the air inside the test box to flow.

[0013] The flow equalizing mechanism includes a flow equalizing housing fixedly connected to the upper part of the test chamber. A fourth motor is provided on the upper part of the flow equalizing housing, and a fan blade is provided at the output end of the fourth motor.

[0014] The transmission mechanism includes a transmission housing fixedly connected inside the test chamber. A third motor is provided inside the transmission housing, and a first transmission component and a second transmission component are provided at the output end of the third motor.

[0015] While the first transmission component drives the first rack to move back and forth, the second transmission component drives the second rack to move up and down.

[0016] The first transmission component includes a worm provided at the output end of the third motor. The worm is meshed and connected with a worm wheel. The worm wheel is rotatably connected to the transmission housing. A second gear is fixedly connected to the side of the worm wheel away from the transmission housing. The second gear is meshed and connected with a first rack. A vibration frame is fixedly connected to the front end of the first rack.

[0017] The second transmission component includes a first gear fixedly connected to the side of the second motor away from the third motor. The first gear is meshed and connected with a second rack. A connecting rod is fixedly connected to the upper part of the second rack. An activity baffle is fixedly connected to the front end of the connecting rod. The activity baffle is slidably connected to the test chamber.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, before the aging test of the aluminum electrolytic capacitor, the capacitor can be placed in the middle position between the clamping members. Then, by starting the clamping mechanism, the clamping members on both sides can be driven to close inward, so as to effectively clamp and fix the capacitor. Moreover, the clamping distance can be flexibly adjusted according to the specifications of the capacitor, effectively ensuring the stability of the capacitor during the test. When vibration testing of the capacitor is required, the operator does not need to fix the capacitor to the vibrator. Just start the vibration mechanism below the clamping mechanism. The vibration mechanism can drive the clamping mechanism to vibrate up and down at high frequency. And the clamping mechanism provides a stable clamping force to ensure that the capacitor always remains stable during the test, thus ensuring the reliability and safety of the test. At the same time, when testing capacitors of different specifications, there is no need to replace the fixing seat.

[0020] 2. In the present invention, after the capacitor is fixed to the clamping mechanism, the transmission mechanism can be started. Through the transmission mechanism, the first transmission component and the second transmission component provided inside can be driven to operate simultaneously. The first transmission component can drive the first rack to move, so as to bring the capacitor into the test chamber. And the second transmission component can drive the second rack to move downward, thereby driving the activity baffle to descend and closing the whole test chamber. Through the transmission mechanism, while driving the capacitor into the test chamber, the activity baffle can be controlled to close. After the capacitor enters the test chamber, the activity baffle also closes the test chamber synchronously. The two actions are carried out synchronously, effectively improving the testing efficiency of the device. Brief Description of the Drawings

Detailed Embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] As Figures 1 - 7As shown in the figure, an aging vibration test device includes a test chamber 1. A transmission mechanism is arranged inside the test chamber 1. The front end of the transmission mechanism is fixedly connected with a vibration mechanism, and the upper part of the vibration mechanism is fixedly connected with a clamping mechanism. The clamping mechanism includes a clamping housing 3 fixedly connected to the upper part of the vibration mechanism. A first motor 5 is arranged on the upper part of the clamping housing 3. A fifth gear 24 is arranged at the output end of the first motor 5. A seventh gear 26 and a sixth gear 25 are meshed and connected on both sides of the fifth gear 24. An eighth gear 27 is meshed and connected on the side of the sixth gear 25 away from the fifth gear 24. The seventh gear 26 and the eighth gear 27 are meshed and connected with a clamping member 4. By driving the fifth gear 24 to rotate through the first motor 5, the rotation of the fifth gear 24 drives the seventh gear 26 and the eighth gear 27 to rotate, and then drives the clamping members 4 on both sides to move and close, so as to clamp and fix aluminum electrolytic capacitors of different specifications.

[0032] The vibration mechanism includes a vibration frame 7 fixedly connected to the front part of the transmission mechanism. A second motor 8 is arranged on one side of the vibration frame 7. A third gear 21 is arranged at the output end of the second motor 8. A fourth gear 22 is meshed and connected above the third gear 21. The fourth gear 22 is rotatably connected with the vibration frame 7. Eccentric shafts 23 are rotatably connected on both sides of the fourth gear 22. A vibration table 9 is rotatably connected on the side of the eccentric shaft 23 away from the fourth gear 22. The vibration table 9 is slidably connected with the vibration frame 7. The clamping housing 3 is fixedly connected to the upper part of the vibration table 9. By driving the eccentric shafts 23 to rotate through the second motor 8, the rotation of the eccentric shafts 23 drives the vibration table 9 to vibrate up and down, and then drives the fixedly connected clamping mechanism and the capacitor clamped by the clamping mechanism to vibrate. An observation window is arranged on one side of the test chamber 1, and the material of the observation window is transparent.

[0033] A feeding port 2 is arranged at the front end of the test chamber 1, and the clamping mechanism passes through the feeding port 2. A temperature control device 10 is arranged inside the test chamber 1, and the temperature inside the test chamber 1 is adjusted through the temperature control device 10. A flow equalizing mechanism is arranged on the upper part of the test chamber 1, and the flow equalizing mechanism drives the air flow inside the test chamber 1. The flow equalizing mechanism includes a flow equalizing housing 11 fixedly connected to the upper part of the test chamber 1. A fourth motor 28 is arranged on the upper part of the flow equalizing housing 11. A fan blade 29 is arranged at the output end of the fourth motor 28.

[0034] In this embodiment, before the aging test of the aluminum electrolytic capacitor, first place the capacitor in the middle position of the clamping member 4, then start the first motor 5. The first motor 5 drives the fifth gear 24 to rotate. The rotation of the fifth gear 24 drives the seventh gear 26 and the sixth gear 25 to rotate. At the same time, the rotation of the fifth gear 24 can also drive the eighth gear 27 to rotate. The rotation of the seventh gear 26 and the eighth gear 27 drives the clamping members 4 on both sides to close inward, thereby effectively clamping and fixing the capacitor. Moreover, the clamping distance can be flexibly adjusted according to different specifications of the capacitor, effectively ensuring the stability of the capacitor during the test. When the capacitor enters the interior of the test chamber 1, the temperature inside the test chamber 1 can be controlled by the temperature control device 10 to reach the aging test standard. Moreover, by starting the fourth motor 28, the fan blade 29 can be driven to rotate. The rotation of the fan blade 29 drives the air flow inside the test chamber 1, thereby ensuring uniform temperature distribution inside the test chamber 1 and effectively improving the test accuracy. The high-temperature test in this device is an auxiliary test, and no additional high-temperature test is required, effectively increasing the convenience of the device.

[0035] When vibration testing of the capacitor is required, there is no need for personnel to fix the capacitor to the vibrator. Only by starting the second motor 8 can the third gear 21 be driven to rotate. The rotation of the third gear 21 drives the fourth gear 22 to rotate. The rotation of the fourth gear 22 drives the eccentric shafts 23 on both sides to rotate. The rotation of the eccentric shafts 23 drives the vibration table 9 connected by rotation to vibrate up and down. The vibration of the vibration table 9 drives the clamping mechanism fixedly connected thereto to vibrate up and down at a high frequency. The clamping mechanism provides a stable clamping force to ensure that the capacitor remains stable during the test, thereby ensuring the reliability and safety of the test. At the same time, when testing capacitors of different specifications, there is no need to replace the fixed seat. During the test, a measuring instrument is used to monitor parameters such as the voltage, current, and temperature of the capacitor in real time, record the vibration time, vibration frequency, amplitude, and parameter changes of the capacitor during the test. Special attention should be paid to the abnormal performance of the capacitor during vibration, such as loosening, damage, or performance degradation caused by vibration. After the test, the recorded data is analyzed to evaluate the durability and reliability of the capacitor in a vibrating environment.

[0036] Embodiment 2

[0037] As Figures 1 - 7 shown, the transmission mechanism includes a transmission housing 6 fixedly connected inside the test chamber 1. A third motor 16 is arranged inside the transmission housing 6. The output end of the third motor 16 is provided with a first transmission component and a second transmission component. While the first transmission component drives the first rack 12 to move back and forth, the second transmission component drives the second rack 13 to move up and down.

[0038] The first transmission assembly includes a worm 17 disposed at the output end of a third motor 16. The worm 17 is meshed and connected with a worm gear 19. The worm gear 19 is rotatably connected to a transmission housing 6. A second gear 20 is fixedly connected to the side of the worm gear 19 away from the transmission housing 6. The second gear 20 is meshed and connected with a first rack 12. A vibration frame 7 is fixedly connected to the front end of the first rack 12. The second transmission assembly includes a first gear 18 fixedly connected to the side of the worm 17 away from the third motor 16. The first gear 18 is meshed and connected with a second rack 13. A connecting rod 14 is fixedly connected to the upper part of the second rack 13. A movable baffle 15 is fixedly connected to the front end of the connecting rod 14. The movable baffle 15 is slidably connected to a test box 1.

[0039] In this embodiment, after the capacitor is fixed to the clamping mechanism, the third motor 16 can be started. The worm 17 is driven to rotate by the third motor 16. The rotation of the worm 17 can drive the meshed worm gear 19 to rotate. The rotation of the worm gear 19 can drive the fixedly connected second gear 20 to rotate. The rotation of the second gear 20 can drive the meshed first rack 12 to move. At the same time, the rotation of the worm 17 can also drive the first gear 18 to rotate synchronously. The rotation of the first gear 18 can drive the meshed second rack 13 to move. The movement of the first rack 12 can bring the capacitor into the test box 1. While the first rack 12 moves, the second rack 13 moves downward, thereby driving the movable baffle 15 to move downward to close the whole test box 1. Through the transmission mechanism, while driving the capacitor into the test box 1, the movable baffle 15 can be controlled to close. After the capacitor enters the test box 1, the movable baffle 15 also closes the test box 1 synchronously. The two actions are carried out synchronously, effectively improving the testing efficiency of the device.
