Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic impregnation machines, and particularly to a fully automatic hydraulic impregnation machine. Background Art

[0002] A fully automatic hydraulic impregnation machine is a key device used in the manufacturing process of capacitors. It is mainly used to immerse capacitor elements in electrolyte solution to complete the impregnation process of capacitors. Through automatic control and a hydraulic system, this device can achieve an efficient and precise impregnation process, improving production efficiency and product quality.

[0003] Currently, for the existing hydraulic impregnation machines, the capacitors to be impregnated are usually directly placed in the hollow container inside the impregnation tank, and only the hydraulic pressure of the hydraulic impregnation machine itself is used to make the electrolyte impregnate into the capacitors. However, the capacitors placed in the hollow container always remain static, which will increase the difficulty of impregnating the electrolyte into the capacitors. Therefore, it is necessary to improve it to enhance the impregnation effect of the hydraulic impregnation machine on the capacitors. Summary of the Invention

[0010] Preferably, an installation shell is fixedly installed on the top surface of the cover plate and extends into the interior of the cover plate. Abuttment plates are symmetrically arranged on both sides of the cover plate.

[0011] Preferably, two threaded cylinders are arranged inside the installation shell. Threaded rods are arranged inside the two threaded cylinders. One ends of the two threaded rods are respectively fixedly connected to the two abutment plates. A connecting worm gear is fixedly connected between the two threaded cylinders. A connecting worm is meshed and connected to one side of the connecting worm gear. The top end of the connecting worm is fixedly connected to a screwing block.

[0012] Preferably, a guide rod is arranged between the two abutment plates, and both ends of the guide rod are respectively fixedly connected to one side of the two abutment plates.

[0013] Preferably, a control panel is arranged on the top of the machine body. The reflux pump is respectively communicated with the interiors of the impregnation tank and the liquid storage tank through a connecting pipe. Electric heating wires are arranged inside the impregnation cylinder. A pressure gauge is arranged on the outer surface of the sealing cover.

[0014] Preferably, a usage method of a full-automatic hydraulic impregnating machine includes the following steps: S1. Place the capacitor inside the hollow-out tank, close the sealing cover to make the impregnation tank in a sealed state. Turn on the reflux pump to allow the electrolyte in the liquid storage tank to flow into the interior of the impregnation tank. Turn on the hydraulic system, and the hydraulic system can pressurize the electrolyte inside the impregnation tank. During the pressurization process, the electrolyte can penetrate into the interior of the capacitor, thereby performing impregnation processing on it; S2. Turn on the motor. The motor can drive the first connecting rod to rotate. The first connecting rod drives the first worm to rotate. The first worm drives the worm gear ring to rotate. The worm gear ring drives the hollow-out tank to rotate. The rotation of the hollow-out tank can increase the contact effect between the electrolyte and the capacitor, thereby making the impregnation more thorough; S3. The first connecting rod rotates, which can drive the rotation of another first connecting rod through the second connecting belt. The rotation of the two first connecting rods can drive the rotation of the second connecting rod through the first connecting belt. The second connecting rod drives the rotation of the two third connecting rods in the bearing through the third connecting belt. When the third connecting rod rotates, it can drive the installation box to rotate. The installation box drives the vibration block to rotate. The vibration block contacts the hollow can, and at the same time, it squeezes the telescopic spring inward through the pressing plate. When the vibration block repeatedly contacts the surface of the hollow can at a high frequency, it can vibrate the hollow can. The small-amplitude vibration can make the bubbles inside the capacitor easier to discharge, allowing the electrolyte to better fill the space inside the capacitor and improving the impregnation effect. S4. By turning the turning block, the turning block drives the connecting worm to rotate. The connecting worm drives the connecting worm to rotate. The connecting worm gear drives the two threaded cylinders to rotate synchronously. The threaded cylinders drive the threaded rods to extend to both sides. When the threaded rods extend, they can push the abutting plate to move. When the abutting plate contacts the surface of the hollow can, the position of the cover plate can be positioned, so that the position of the cover plate can be adjusted arbitrarily, ensuring the space at the top of the capacitor inside the hollow can and further enhancing the contact effect between the capacitor and the electrolyte.

[0015] Working principle: When using this device, place the device at the designated position, open the sealing cover, place the capacitor to be impregnated inside the hollow can, place the cover plate inside the hollow can and at a suitable height. Rotate the turning block, the turning block drives the connecting worm to rotate, the connecting worm drives the connecting worm gear to rotate, the connecting worm gear drives the two threaded cylinders to rotate, and the threaded cylinders drive the two threaded rods to extend to both sides. When the threaded rods extend, they can push the abutting plate to move. When the abutting plate contacts the inner wall of the hollow can, the position of the cover plate can be positioned, so that there is still a certain space between the capacitor and the cover plate, increasing the contact area between the electrolyte and the capacitor.

[0016] Close the sealing cover, turn on the vacuum pump. The vacuum pump can pump out the air inside the impregnation tank through the pumping pipe, making the inside of the impregnation tank in a vacuum state. Through the reflux pump, the electrolyte inside the liquid storage tank can be transported into the impregnation tank. Turn on the hydraulic system, and the hydraulic system pressurizes the inside of the impregnation tank, so that the electrolyte can be impregnated into the capacitor.

[0017] During the impregnation process, turn on the motor. The motor drives one of the first connecting rods to rotate. The first connecting rod drives the first worm to rotate. The first worm drives the worm gear ring to rotate. The worm gear ring drives the hollow can to rotate stably inside the impregnation tank. The rotating hollow can can deflect the capacitor inside it, thereby increasing the contact effect between the electrolyte and the capacitor and enhancing the impregnation effect.

[0018] When the first connecting rod rotates, it can drive another first connecting rod to rotate through the second connecting belt. When the two first connecting rods rotate, they can drive the second connecting rod to rotate through the first connecting belt. When the two second connecting rods rotate, they can drive the third connecting rod to rotate through the third connecting belt. The two third connecting rods drive the installation box to rotate, and the installation box drives the vibration block to rotate. The vibration block rotates at a high frequency and contacts the hollow can, so as to vibrate both sides of the hollow can. A small-amplitude vibration can make the bubbles inside the capacitor easier to discharge, allowing the electrolyte to better fill the space inside the capacitor and improving the impregnation effect.

[0019] The present invention provides a fully automatic hydraulic impregnating machine. It has the following beneficial effects: 1. In the present invention, by setting a rotating assembly, when in use, the motor can be started, the motor drives the first connecting rod to rotate, the first connecting rod drives the first worm to rotate, the first worm drives the worm gear ring to rotate, and the worm gear ring can drive the hollow can to rotate at a high speed inside the impregnating tank, or the capacitor inside it can be deflected. Rotating the capacitor can make the electrolyte contact each part of the capacitor core more fully, allowing the electrolyte to better penetrate into the inside of the winding structure and fill the tiny gaps and pores therein, making the impregnation more uniform and thorough.

[0020] 2. In the present invention, when one of the first connecting rods rotates, it can drive another first connecting rod to rotate through the second connecting belt. The two first connecting rods drive the second connecting rod to rotate through the first connecting belt. The second connecting rod drives the third connecting rod to rotate inside the bearing through the third connecting belt. The third connecting rod drives the installation box to rotate, and the installation box drives the vibration block to rotate. During the rotation of the vibration block, it can knock on the hollow can at a high frequency and quickly, thereby vibrating it. A small-amplitude vibration can make the bubbles inside the capacitor easier to discharge, allowing the electrolyte to better fill the space inside the capacitor and improving the impregnation effect.

[0021] 3. In the present invention, by rotating the connecting worm, the connecting worm drives the connecting worm wheel to rotate, the connecting worm wheel drives the threaded cylinder to rotate, the threaded cylinder can drive the threaded rod to stretch, and the stretching of the threaded rod can push the abutting plate to move, so that the abutting plate can be in contact with the inner wall of the hollow can, increasing the friction between the abutting plate and the hollow can, and then positioning the position of the cover plate, thereby ensuring the space at the top of the capacitor and further increasing the impregnation effect on the capacitor.

Detailed implementation manners

[0024] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the attached Figure 1 - attached Figure 4 , an embodiment of the present invention provides a fully automatic hydraulic impregnating machine, including a body 1, an impregnation tank 2 is fixedly installed inside the body 1, a hollow tank 10 is arranged inside the impregnation tank 2, a rotating assembly is fixedly connected to the outside of the hollow tank 10, a cover plate 11 is arranged inside the hollow tank 10, a hydraulic system 28 is arranged inside the impregnation tank 2, a liquid storage tank 4 is fixedly connected inside the body 1, a vacuum pump 6 is arranged between the impregnation tank 2 and the liquid storage tank 4, a sealing cover 3 is movably installed on the top surface of the impregnation tank 2, a reflux pump 5 is arranged inside the body 1, and two extraction pipes 8 are arranged on one side of the vacuum pump 6.

[0026] Specifically, the hydraulic system 28 is arranged inside the impregnation tank 2. The overall equipment realizes the pressure control of the impregnation tank 2 through the hydraulic system 28, which can increase the pressure inside the impregnation tank 2, shorten the impregnation time, improve the impregnation efficiency and quality. The hydraulic system 28 can also ensure the pressure stability during the impregnation process and avoid the secondary pollution of the electrolyte. The two extraction pipes 8 are respectively connected to the sealing cover 3 and the liquid storage tank 4. When in use, the sealing cover 3 can be closed to make the inside of the impregnation tank 2 in a sealed state. By turning on the vacuum pump 6, the vacuum pump 6 can evacuate the inside of the impregnation tank 2 and the liquid storage tank 4 to make the internal space in a vacuum state. At this time, the electrolyte can be added to the inside of the impregnation tank 2, and the electrolyte in the impregnation tank 2 can be pressurized through the hydraulic system 28 at the bottom of the impregnation tank 2, so as to carry out the impregnation process on the capacitor. The surface of the hollow cylinder is designed with a hollow structure, so that the electrolyte can easily pass through the hollow tank 10 to contact the capacitor.

[0027] Please refer to the attached Figure 3 - attached Figure 5 As shown in the figure, the rotating assembly includes a worm gear ring 13, a first worm 14, a first connecting rod 15 and a motor 18. The worm gear ring 13 is fixedly sleeved on the outer surface of the hollow tank 10. The first worm 14 is meshed with the worm gear ring 13. The first connecting rod 15 is fixedly installed at one end of the first worm 14. The motor 18 is arranged inside the impregnation tank 2, and the output end of the motor 18 is connected to the first connecting rod 15.

[0028] Specifically, the worm gear ring 13 is arranged around the outer side of the hollow tank 10, and the outer surfaces of the worm gear ring 13 and the first worm 14 are both electroplated with nickel element. Through the hydrophobic and low-reactive nickel-phosphorus alloy coating, the parts of the device can be isolated from the electrolyte, preventing the electrolyte from reacting chemically with the part substrate, and thus preventing the metal from being corroded. A support frame for supporting the hollow tank 10 is arranged inside the impregnation tank 2, and the hollow tank 10 is rotatably connected to the fixed frame inside it through rollers, which not only ensures the stability of the hollow tank 10 inside the impregnation tank 2, but also enables the hollow tank 10 to rotate stably. When the first worm 14 drives the worm gear ring 13 to rotate, the worm gear ring 13 can drive the hollow tank 10 to rotate. When the hollow tank 10 rotates, it can drive the capacitor inside it to deflect. The capacitor during the deflection process can increase its contact effect with the electrolyte and improve the impregnation quality.

[0029] Please refer to the attached Figure 5 As shown in the figure, a second connecting belt 17 is connected between the two first connecting rods 15 through a pulley. Second connecting rods 19 are symmetrically arranged inside the impregnation tank 2, and a first connecting belt 16 is connected between the first connecting rod 15 and the second connecting rod 19 through a pulley. A third connecting rod 21 is arranged on one side of the two second connecting rods 19, and a third connecting belt 20 is connected between the third connecting rod 21 and the second connecting rod 19 through a pulley.

[0030] Specifically, the length of one of the two first connecting rods 15 is longer than that of the other. When one of the first connecting rods 15 rotates, it can drive the second connecting belt 17 to rotate through a pulley. The second connecting belt 17 can then drive the other first connecting rod 15 to rotate. The two first connecting rods 15 rotate synchronously, and can drive the second connecting rod 19 to rotate through the first connecting belt 16. The two second connecting rods 19 can drive the third connecting rod 21 to rotate through the third connecting belt 20, so as to ensure the synchronism when the two third connecting rods 21 rotate.

[0031] Please refer to the attached Figure 5 , bearings 23 are connected to both ends of the two third connecting rods 21. A fixing rod 22 is fixedly connected to one side of the bearing 23, and one end of the fixing rod 22 is fixedly installed on the inner wall of the impregnation tank 2.

[0032] Specifically, through the two bearings 23, the stability when the third connecting rod 21 rotates can be ensured. The two fixing rods 22 are fixedly installed on the inner wall of the impregnation tank 2, and thus can support the bearings 23 and the third connecting rod 21.

[0033] Please refer to the attached Figure 6 , a mounting box 24 is fixedly connected to the center of the third connecting rod 21. Two telescopic springs 27 are provided inside the mounting box 24. The bottom end of the telescopic spring 27 is fixedly connected to a pressing plate 25, and a vibrating block 26 is fixedly connected to the bottom surface of the pressing plate 25.

[0034] Specifically, the mounting box 24 is fixedly installed at the center of the third connecting rod 21, and the two mounting boxes 24 are also located on both sides of the hollow tank 10. When the third connecting rod 21 rotates, it can drive the mounting box 24 to rotate. The mounting box 24 can drive the vibrating block 26 to rotate. The vibrating block 26 is convex. When the vibrating block 26 rotates to a specified position, it will contact the hollow tank 10. When the vibrating block 26 contacts the surface of the hollow tank 10, it will press the telescopic spring 27 inward through the pressing plate 25. When the vibrating block 26 rotates repeatedly at a high frequency, it can continuously abut against both sides of the hollow tank 10, and thus can vibrate both sides of the hollow tank 10. When the hollow tank 10 vibrates slightly, the bubbles inside the capacitor can be more easily discharged, allowing the electrolyte to better fill the space inside the capacitor and improving the impregnation effect.

[0035] Please refer to the attached Figure 7 , a mounting shell 12 is fixedly installed on the top surface of the cover plate 11, and the mounting shell 12 extends into the inside of the cover plate 11. Contact plates 29 are symmetrically provided on both sides of the cover plate 11.

[0036] Specifically, the surfaces of the two abutting plates 29 are provided with anti-slip patterns. By contacting the inner wall of the hollow can 10 with the two abutting plates 29, the position of the cover plate 11 can be positioned. In the traditional hollow can 10, when impregnating the capacitor, the cover plate 11 is usually pressed on the top surface of the capacitor, which results in incomplete impregnation of the top surface of the capacitor, thereby affecting the impregnation effect. In this device, by abutting the abutting plate 29 against the inner wall of the hollow can 10, the height of the cover plate 11 can be adjusted, so that a certain space is still left at the top of the capacitor, and thus the impregnation effect can be further enhanced.

[0037] Please refer to the attached Figure 8 , there are two threaded cylinders 30 inside the mounting shell 12. There are threaded rods 31 inside the two threaded cylinders 30, and one ends of the two threaded rods 31 are respectively fixedly connected to the two abutting plates 29. A connecting worm gear 32 is fixedly connected between the two threaded cylinders 30. A connecting worm 33 is meshed and connected to one side of the connecting worm gear 32. The top end of the connecting worm 33 is fixedly connected with a screwing block 35.

[0038] Specifically, the threaded rod 31 is threadedly connected with the threaded cylinder 30. Thus, when the threaded cylinder 30 is rotated to limit the threaded rod 31, the threaded rod 31 can be driven to expand and contract inside the threaded cylinder 30. When the threaded rod 31 expands and contracts, the two abutting plates 29 on both sides can be pushed to move relatively, and the threads on the surfaces of the two threaded cylinders 30 and the two threaded rods 31 are set completely oppositely. Therefore, when the two threaded cylinders 30 rotate synchronously and in the same direction, it can be ensured that the two threaded rods 31 extend towards both sides.

[0039] Please refer to the attached Figure 8 , a guide rod 34 is provided between the two abutting plates 29, and both ends of the guide rod 34 are respectively fixedly connected to one side of the two abutting plates 29.

[0040] Please refer to the attached Figure 1 - attached Figure 4 , a control panel 7 is provided on the top of the machine body 1. The reflux pump 5 is respectively communicated with the inside of the impregnation tank 2 and the storage tank 4 through a connecting pipe. An electric heating wire 36 is provided inside the impregnation cylinder. A pressure gauge 9 is provided on the outer surface of the sealing cover 3.

[0041] Specifically, this device is controlled by PLC programming and through a touch screen. The operator only needs to click the "Run" soft key or manually operate the key, and the device can automatically or manually complete the impregnation operation. Moreover, PLC control technology is widely used in various industries, and its technical means are relatively mature, so there is no need to elaborate on it here. By turning on the heating wire 36, this device can heat the electrolyte to a specified temperature, which is more conducive to the impregnation operation and increases the functionality of this device. Also, when the impregnation is completed, the heating wire 36 can be turned on to heat the temperature inside the impregnation tank 2. By rotating the hollow tank 10, the capacitors inside it can be rotated, thereby increasing the drying efficiency of the capacitors and further enhancing the functionality of this device.

[0042] Specifically, both ends of the guide rod 34 are telescopic. Thus, when the threaded rod 31 expands and contracts to drive the two abutting plates 29 to move, the guide rod 34 can expand and contract accordingly, thereby increasing the smoothness and directivity of the movement of the two abutting plates 29.

[0043] Please refer to the appendix Figure 1 - appendix Figure 8 , a method for using a fully automatic hydraulic impregnating machine, including the following steps: S1. Place the capacitor inside the hollow tank 10, close the sealing cover 3 to make the impregnation tank 2 in a sealed state, turn on the reflux pump 5 to allow the electrolyte in the liquid storage tank 4 to flow into the inside of the impregnation tank 2, and turn on the hydraulic system 28. The hydraulic system 28 can then pressurize the electrolyte inside the impregnation tank 2. During the pressurization process, the electrolyte can penetrate into the capacitor, thereby performing impregnation processing on it; S2. By turning on the motor 18, the motor 18 can drive the first connecting rod 15 to rotate. The first connecting rod 15 drives the first worm 14 to rotate. The first worm 14 drives the worm gear ring 13 to rotate. The worm gear ring 13 drives the hollow tank 10 to rotate. The rotation of the hollow tank 10 can increase the contact effect between the electrolyte and the capacitor, thereby making the impregnation more thorough; S3. When the first connecting rod 15 rotates, it can drive another first connecting rod 15 to rotate through the second connecting belt 17. The rotation of the two first connecting rods 15 can drive the second connecting rod 19 to rotate through the first connecting belt 16. The second connecting rod 19 drives the two third connecting rods 21 to rotate inside the bearing 23 through the third connecting belt 20. When the third connecting rod 21 rotates, it can drive the installation box 24 to rotate. The installation box 24 drives the vibration block 26 to rotate. The vibration block 26 is in contact with the hollow tank 10, and at the same time, it squeezes the telescopic spring 27 inward through the pressing plate 25. When the vibration block 26 repeatedly and frequently contacts the surface of the hollow tank 10, it can vibrate the hollow tank 10. A small - amplitude vibration can make the bubbles inside the capacitor easier to discharge, allowing the electrolyte to better fill the space inside the capacitor and improving the impregnation effect; S4. By turning the turning block 35, the turning block 35 drives the connecting worm 33 to rotate. The connecting worm 33 drives the connecting worm 33 to rotate. The connecting worm wheel 32 drives the two threaded cylinders 30 to rotate synchronously. The threaded cylinders 30 drive the threaded rods 31 to extend towards both sides. When the threaded rods 31 extend, the abutting plate 29 can be pushed to move. When the abutting plate 29 is in contact with the surface of the hollow can 10, the position of the cover plate 11 can be positioned, so that the position of the cover plate 11 can be adjusted arbitrarily, ensuring the space at the top of the capacitor inside the hollow can 10 and further enhancing the contact effect between the capacitor and the electrolyte.
