Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic capacitor technology, and in particular to an aging device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitor aging equipment is a specialized equipment system used to "age" or "enhance" aluminum electrolytic capacitors. By simulating actual working conditions or accelerating the aging process, the performance of the capacitors is stabilized, and products that fail early are screened out.

[0003] Currently, most aluminum electrolytic capacitors have relatively simple aging methods, which are not conducive to simulating aging in multiple environments. This makes the detection of aluminum electrolytic capacitors after aging inaccurate, which in turn reduces the overall reliability and applicability of the product.

[0004] To address the aforementioned problems, this utility model document proposes an aging device for aluminum electrolytic capacitors. Utility Model Content

[0005] This invention provides an aging device for aluminum electrolytic capacitors, which solves the problem that in the prior art, most aluminum electrolytic capacitors have a relatively simple aging method, which is not conducive to simulating aging in multiple environments. This makes the detection of aluminum electrolytic capacitors after aging inaccurate, which in turn reduces the overall reliability and applicability of the product.

[0006] This utility model provides the following technical solution:

[0007] An aging device for aluminum electrolytic capacitors, comprising:

[0008] The base plate has an aging chamber welded to its top side. A placement tray is fixedly installed between the inner walls of the two sides of the aging chamber. The top of the placement tray has multiple placement slots for placing aluminum electrolytic capacitors.

[0009] Electric heating plates are fixedly installed on both sides of the inner wall of the aging chamber to heat the aluminum electrolytic capacitors placed in the tank to simulate aging. A temperature sensor is fixedly installed on one side of the inner wall of the aging chamber to monitor the temperature inside the aging chamber in real time.

[0010] In one possible design, heat exhaust vents are provided on both sides of the aging chamber, and heat exhaust fans corresponding to the heat exhaust vents are fixedly installed on both sides of the aging chamber to exhaust the heat inside the heated aging chamber to a normal temperature, so as to simulate the aging of aluminum electrolytic capacitors at a normal temperature.

[0011] In one possible design, each of the heat exhaust ports is slidably connected to a plate for sealing the heat exhaust port. A bonding plate is welded to one side of the bonding plate, and a magnet is provided on one side of the bonding plate. An iron block that attracts the magnet is provided on one side of the inner wall of the heat exhaust port.

[0012] In one possible design, a water tank is welded to the top side of the base plate, and a water pump is fixedly installed on the top of the water tank. The inlet and outlet of the water pump are respectively connected to an inlet pipe and an outlet pipe. The end of the inlet pipe away from the water pump passes through the top side of the water tank and extends into the interior of the water tank. The end of the outlet pipe away from the water pump passes through one side of the aging chamber and extends into the interior of the aging chamber.

[0013] In one possible design, the end of the water outlet pipe away from the water pump is connected to a connecting pipe, which is fixed to one side of the inner wall of the aging chamber by a snap ring. The outer wall of the connecting pipe is connected to multiple atomizing nozzles corresponding to the placement trays, which are used to simulate humid aging of the aluminum electrolytic capacitors in the placement tank.

[0014] In one possible design, the top of the aging chamber is rotatably connected to a sealing cover via a hinge, and a sealing gasket is provided on the bottom side of the sealing cover. Two connecting blocks are welded to one side of the aging chamber and one side of the sealing cover, and each pair of connecting blocks is connected and fixed by fasteners. Each set of fasteners includes a bolt and a nut.

[0015] In one possible design, an observation window is provided on one side of the aging chamber.

[0016] In this application, during use, the aluminum electrolytic capacitor is first placed in the placement slot of the placement tray to simulate the high-temperature aging conditions it may encounter in actual use. Then, the sealing cover is connected to the top of the aging chamber via a hinge and closed. When closed, the sealing gasket ensures the airtightness of the aging chamber, preventing heat and humidity leakage. The connecting block and fasteners are used to fix the sealing cover and the aging chamber, ensuring the stability of the equipment during the aging process and achieving easy opening and closing, facilitating the handling of the aluminum electrolytic capacitor. At the same time, the observation window allows the operator to observe the aging condition of the aluminum electrolytic capacitor in the aging chamber without opening the sealing cover. Next, the electric heating plate in the aging chamber is turned on by the controller to start working and generate heat. The temperature sensor monitors the temperature inside the aging chamber in real time and feeds the data back to the control system. When the temperature reaches the preset high-temperature aging conditions, the electric heating plate maintains a constant power output to maintain the high-temperature environment. The aluminum electrolytic capacitor placed in the placement slot of the placement tray is affected by the high temperature, simulating the high-temperature aging conditions it may encounter in actual use.

[0017] When simulating room temperature aging, the plate initially closes the heat dissipation port. However, during heat dissipation, the plate is opened to increase heat dissipation efficiency. Subsequently, the control system commands the heat dissipation fan to start, which expels hot air from the aging chamber through the heat dissipation port, accelerating the drop in internal temperature to room temperature. When the temperature sensor detects that the temperature inside the aging chamber has dropped to room temperature, the control system commands the heat dissipation fan to stop working and may adjust the plate position as needed to maintain a room temperature environment. This cycle between high and room temperature effectively simulates temperature changes in the actual working environment, improving the aging effect and realism. Furthermore, when further heating is needed to simulate aging, the plate is reset and secured using magnets and iron blocks. The aging chamber is sealed to achieve this purpose. Then, the water pump is started by the controller to draw water from the water tank. The water enters the water pump through the inlet pipe and is then delivered to the connecting pipe through the outlet pipe. The connecting pipe is fixed to one side of the inner wall of the aging chamber by a retaining ring. Multiple atomizing nozzles on the connecting pipe are aimed at the aluminum electrolytic capacitors on the placement tray. Water is sprayed out from the atomizing nozzles in a mist form, increasing the humidity inside the aging chamber. This helps to simulate a humid environment for the aluminum electrolytic capacitors. The aluminum electrolytic capacitors become damp in a humid environment, simulating the humid aging conditions that they may encounter in actual use. This allows for the simulation of different aging methods for aluminum electrolytic capacitors, achieving the purpose of simulating aging under multiple environments. This further improves the accuracy of the detection of aluminum electrolytic capacitors after aging and enhances the overall reliability and applicability of the product.

[0018] In this utility model, the aging device for aluminum electrolytic capacitors, through the setting of structures such as electric heating plate, temperature sensor, heat exhaust port and heat exhaust fan, can simulate the high temperature aging situation that aluminum electrolytic capacitors may encounter in actual use, and also helps to maintain a normal temperature environment, thereby cycling between high temperature and normal temperature, which is beneficial to simulating temperature changes in the actual working environment, improving the aging effect and practicality.

[0019] In this utility model, the aging equipment for aluminum electrolytic capacitors, through the setting of a water tank, water pump, connecting pipe and atomizing nozzle, can increase the humidity in the aging chamber, which is beneficial for simulating a humid environment for aluminum electrolytic capacitors. The aluminum electrolytic capacitors become damp in the humid environment, simulating the humid aging conditions that they may encounter in actual use.

[0020] This invention can simulate different aging methods of aluminum electrolytic capacitors, achieving the purpose of simulating aging under multiple environments, further improving the detection accuracy of aluminum electrolytic capacitors after aging, and enhancing the overall reliability and applicability of the product.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] The existing problem in the field of aluminum electrolytic capacitors is that most aluminum electrolytic capacitors have a relatively simple aging method, which is not conducive to simulating aging in multiple environments. This makes the detection of aluminum electrolytic capacitors after aging inaccurate, which in turn reduces the overall reliability and applicability of the product. To address this problem, this solution designs an aging device.

[0030] Please refer to Figures 1-4 An aging device, comprising:

[0031] A base plate 1 is provided, and an aging chamber 2 is welded to the top side of the base plate 1. A placement tray 7 is fixedly installed between the inner walls of both sides of the aging chamber 2. The top of the placement tray 7 is provided with multiple placement slots 8 for placing aluminum electrolytic capacitors. The aluminum electrolytic capacitors are placed in the placement slots 8 of the placement tray 7 to simulate the high-temperature aging conditions that they may encounter in actual use.

[0032] Electric heating plates 9 are fixedly installed on both sides of the inner wall of the aging chamber 2 to heat the aluminum electrolytic capacitors in the placement slot 8 to simulate aging. A temperature sensor 10 is fixedly installed on one side of the inner wall of the aging chamber 2 to monitor the temperature inside the aging chamber 2 in real time. The electric heating plates 9 inside the aging chamber 2 are turned on by the controller to start working and generate heat. The temperature sensor 10 monitors the temperature inside the aging chamber 2 in real time and feeds the data back to the control system. When the temperature reaches the preset high temperature aging condition, the electric heating plates 9 maintain a constant power output to maintain the high temperature environment. The aluminum electrolytic capacitors are placed in the placement slot 8 of the placement tray 7 and are affected by the high temperature to simulate the high temperature aging conditions that they may encounter in actual use.

[0033] Both sides of the aging chamber 2 are provided with heat exhaust vents 11, and both sides of the aging chamber 2 are fixedly equipped with heat exhaust fans 12 corresponding to the heat exhaust vents 11. These fans are used to exhaust the heat inside the heated aging chamber 2 to a normal temperature, so as to simulate the aging of aluminum electrolytic capacitors at a normal temperature. When the heat exhaust fans 12 are started, they exhaust the hot air inside the aging chamber 2 through the heat exhaust vents 11, which helps to accelerate the temperature drop inside the chamber to a normal temperature. When the temperature sensor 10 detects that the temperature inside the aging chamber 2 has dropped to the normal temperature range, the control system commands the heat exhaust fans 12 to stop working and may adjust the position of the plug plate 13 as needed to maintain a normal temperature environment. This cycle between high temperature and normal temperature helps to simulate the temperature changes in the actual working environment, improving the aging effect and practicality.

[0034] Each heat exhaust port 11 has a sliding plate 13 for sealing the heat exhaust port 11. A bonding plate 14 is welded to one side of the bonding plate 13, and a magnet is provided on one side of the bonding plate 14. An iron block 19 that is attracted to the magnet is provided on one side of the inner wall of the heat exhaust port 11. The plate 13 initially seals the heat exhaust port 11, but during the heat exhaust process, the plate 13 is pulled open to increase the heat exhaust efficiency. At the same time, when it is necessary to continue heating to simulate aging, the plate 13 is reset and fixed by the attraction between the magnet and the iron block 19, so as to achieve the purpose of sealing the aging chamber 2.

[0035] A water tank 15 is welded to the top side of the base plate 1. A water pump 16 is fixedly installed on the top of the water tank 15. The inlet and outlet of the water pump 16 are connected to an inlet pipe and an outlet pipe, respectively. The end of the inlet pipe away from the water pump 16 passes through the top side of the water tank 15 and extends into the interior of the water tank 15. The end of the outlet pipe away from the water pump 16 passes through one side of the aging chamber 2 and extends into the interior of the aging chamber 2. The end of the outlet pipe away from the water pump 16 is connected to a connecting pipe 17. The connecting pipe 17 is fixed to one side of the inner wall of the aging chamber 2 by a snap ring. The outer wall of the connecting pipe 17 is connected to multiple atomizing nozzles 18 corresponding to the placement tray 7, which are used to simulate humid aging of the aluminum electrolytic capacitors in the placement tank 8. The water pump 16 is started by the controller to draw water from the water tank 15. The water enters the water pump 16 through the inlet pipe and is then transported to the connecting pipe 17 through the outlet pipe. The connecting pipe 17 is fixed to one side of the inner wall of the aging chamber 2 by a retaining ring. Multiple atomizing nozzles 18 on it are aimed at the aluminum electrolytic capacitors on the placement tray 7. Water is sprayed out from the atomizing nozzles 18 in the form of mist, which increases the humidity in the aging chamber 2. This is beneficial for simulating a humid environment for the aluminum electrolytic capacitors. The aluminum electrolytic capacitors become damp in the humid environment, simulating the humid aging conditions that they may encounter in actual use.

[0036] This application can be used in the field of aluminum electrolytic capacitors, or in other fields applicable to this application.

[0037] The temperature sensor 10 is model DS18B20, and its structure and mechanism will not be described in detail here.

Two connecting blocks 5 are welded to one side of the aging chamber 2 and one side of the sealing cover 3. Each pair of connecting blocks 5 is connected and fixed by fasteners 6. Each set of fasteners 6 includes a bolt and a nut. The sealing cover 3 is connected to the top of the aging chamber 2 by the hinge and is closed. When closed, the sealing gasket 4 can ensure the airtightness of the aging chamber 2 and prevent heat and humidity leakage. The connecting blocks 5 and fasteners 6 are used to fix the sealing cover 3 and the aging chamber 2, ensuring the stability of the equipment during the aging process and achieving convenient opening and closing, which facilitates the handling of aluminum electrolytic capacitors.

[0041] An observation window 20 is provided on one side of the aging chamber 2, which allows the operator to observe the aging of the aluminum electrolytic capacitors inside the aging chamber 2 without opening the sealing cover 3.
