[0029] The terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "radial", "circumferential", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0031] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] See Figure 1 The present invention provides an impregnation apparatus including an impregnation cylinder 10, a loading mechanism 30, and a frame 20. The frame 20 is provided with a first station 201 and a second station 202. The loading mechanism 30 is slidably arranged relative to the frame 20. A plurality of impregnation cylinders 10 are slidably connected to the frame 20. The impregnation cylinders 10 can selectively slide to the first station 201 or the second station 202. The loading mechanism 30 is used to remove and / or place material from the impregnation cylinder 10 located at the second station 202. In this embodiment, the material is a capacitor 40.

[0034] In practical applications, the impregnation equipment is usually composed of multiple impregnation cylinders 10, sliding rails, a driving device, a feeding mechanism 30 and a frame 20. During operation, the capacitor to be impregnated is first loaded into the impregnation cylinder 10 located at the second station 202 by the feeding mechanism 30. Then, the driving device is started, driving the impregnation cylinder 10 to move along the sliding rail to the first station 201. At the same time, another impregnation cylinder 10 moves to the second station 202 to be loaded with capacitors. At the first station 201, the capacitors in the impregnation cylinder 10 are impregnated for a period of time. After the treatment is completed, the impregnation cylinder 10 is driven again by the driving device and moves along the sliding rail to the second station 202. At the second station 202, the feeding mechanism 30 takes out the impregnated capacitors for further processing. In this way, the reciprocating movement of the impregnation cylinder 10 on the sliding rail is used to achieve continuous processing and efficient production of capacitors.

[0035] By rationally configuring the first station 201 and the second station 202, multi-cylinder collaborative operation is achieved, enhancing the overall performance of the equipment. The impregnation cylinder 10 can slide between the first station 201 and the second station 202, which means that while one impregnation cylinder 10 is performing the impregnation process, another impregnation cylinder 10 can be loading or unloading materials. This parallel operation method greatly shortens the production cycle and improves overall production efficiency. Through the sliding design of the impregnation cylinder 10, multiple impregnation cylinders 10 can share a loading mechanism 30, thereby reducing the structural complexity of the equipment and reducing the device's footprint.

[0036] See Figure 6The feeding mechanism 30 includes a fixed plate 301, a pushing block 303 and two clamping plates 302. At least one clamping plate 302 is slidably connected to the fixed plate 301, and the two clamping plates 302 are used to clamp the material; the pushing block 303 is movably connected to the fixed plate 301, and the pushing block 303 is used to push the material between the two clamping plates 302 into the clamping part of the impregnation cylinder.

[0037] In actual application, if the capacitor element 40 in the impregnation cylinder is impregnated after completion, the capacitor element 40 needs to be taken out and a new capacitor element 40 to be impregnated is placed. Therefore, the moving mechanism of the present application is provided with a push block 303. When the capacitor element 40 in the impregnation cylinder is impregnated after completion, the impregnation cylinder moves to the second station again. One side of the second station has a strip groove, and the upper end of the strip groove and the end close to the impregnation cylinder have openings. A row of capacitor elements 40 can be placed in the strip groove, and the push block 303 can push the row of capacitor elements 40 from the direction of the other end of the strip groove, so that the row of capacitor elements 40 is pushed out from the opening close to one end of the impregnation cylinder and enters the clamping assembly of the impregnation cylinder. In a specific application, first, the two clamping plates 302 clamp the capacitor 40 to be impregnated and move it to a designated position (strip groove). The two clamping plates 302 are relatively opened and the clamped capacitor 40 is released to place the capacitor 40 in the strip groove. After the impregnation cylinder is opened to expose the impregnated capacitor 40, the push block 303 is moved. The push block 303 pushes the capacitor 40 between the clamping plates 302 and located in the strip groove out of the opening of the strip groove and sequentially advances it into the clamping assembly in the impregnation cylinder. At the same time, the new capacitor 40 can squeeze out a row of capacitors 40 corresponding to the clamping assembly in the impregnation cylinder in sequence to the slot on the other side of the impregnation cylinder (for example, a movable discharge trough, which can be docked to the second side opening of the clamping assembly), thereby placing the capacitor 40 to be impregnated and removing the impregnated capacitor 40. Ensure the continuity and automation of the entire impregnation process. The capacitor can be placed in and taken out simultaneously by relying on the push block 303 without multiple steps, which greatly simplifies the operation steps and improves work efficiency.

[0038] See Figure 2 The above-mentioned impregnation cylinder 10 includes a cylinder body 1, a roller rack 2 and a clamping assembly 3, and the roller rack 2 is rotatably connected to the cylinder body 1; the roller rack 2 is connected to multiple clamping assemblies 3 along its circumference; wherein the clamping assembly 3 includes a first clamping piece 31 and a second clamping piece 32, and the first clamping piece 31 and the second clamping piece 32 are both rotatably connected to the roller rack 2, and the first clamping piece 31 extends obliquely from one end of the roller rack 2 to the direction close to the second clamping piece 32, and the second clamping piece 32 extends obliquely from one end of the roller rack 2 to the direction close to the first clamping piece 31.

[0039] In actual application, the clamping assembly 3 includes a first clamping piece 31 and a second clamping piece 32. The first clamping piece 31 and the second clamping piece 32 are both connected to the roller frame 2. The first clamping piece 31 is tilted toward the direction close to the second clamping piece 32, and the second clamping piece 32 is tilted toward the direction close to the first clamping piece 31. In the direction away from the roller frame 2, the distance between the first clamping piece 31 and the second clamping piece 32 gradually decreases, forming an "eight" structure. The "eight" structure increases the contact area between the clamping piece and the capacitor 40, thereby improving the clamping stability. The rotation connection of the roller frame 2 allows the capacitor to be evenly impregnated, improving the impregnation effect.

[0040] The multiple clamping assemblies 3 are positioned at equal distances from the central axis of the roller frame 2, ensuring uniform force on each capacitor during rotation and avoiding uneven impregnation caused by eccentricity. This symmetrical layout also simplifies the mechanical structure, reduces manufacturing costs, improves the smoothness of equipment operation, and further enhances the overall performance of the production line.

[0041] Compared with the prior art, the clamping assembly 3 of the present application adopts an inclined design, which effectively solves the stability problem of the capacitor during the impregnation process, improves the impregnation uniformity, reduces the defective rate, and ensures the stability of product quality.

[0042] See Figure 3 A plurality of elastic protrusions 33 are provided on a side of the first clamping piece 31 facing the second clamping piece 32 , and / or a plurality of elastic protrusions 33 are provided on a side of the second clamping piece 32 facing the first clamping piece 31 .

[0043] In actual application, a plurality of elastic protrusions 33 are provided on one side of the first clamping piece 31 facing the second clamping piece 32. The elastic protrusions 33 increase the clamping force, ensuring that the capacitor does not fall off during high-speed rotation, thereby improving safety. The design of the elastic protrusions 33 can also adapt to capacitors of different sizes, enhancing the versatility of the device and further optimizing the production process. The provision of the elastic protrusions 33 not only ensures the stability of the clamping, but also avoids excessive pressure on the capacitor, thereby extending the service life of the capacitor.

[0044] It is understandable that the second clamping piece 32 is also provided with a plurality of elastic protrusions 33 on the side facing the first clamping piece 31 , which cooperate with the first clamping piece 31 to form a double clamping mechanism, further enhancing the fixing effect of the capacitor.

[0045] See Figure 7The above-mentioned elastic protrusion 33 includes a connecting surface 331, a supporting surface 332 and a peripheral surface 333. The connecting surface 331 is connected to the first clamping piece 31 or the second clamping piece 32. The supporting surface 332 and the connecting surface 331 are arranged opposite to each other. The supporting surface 332 is used to contact the material. The peripheral surface 333 is respectively connected to the supporting surface 332 and the connecting surface 331. The peripheral surface 333 at least partially shrinks in the direction close to the supporting surface 332.

[0046] In practice, the elastic protrusion 33 comprises a connecting surface 331, a supporting surface 332, and a peripheral surface 333. The connecting surface 331 is tightly coupled to the first clamping piece 31 or the second clamping piece 32, while the supporting surface 332 precisely conforms to the surface of the capacitor to ensure a secure clamping. The constricted design of the peripheral surface 333 increases elasticity, effectively buffering vibrations and preventing damage to the capacitor. The flat surface 332 maximizes contact area with the capacitor, improving uniformity and stability of the clamping.

[0047] See Figure 4 The clamping assembly 3 includes a baffle 34, and the first clamping piece 31 is connected to the baffles 34 at both opposite ends along its length direction, and the baffle 34 extends in the direction close to the second clamping piece 32 to exceed the first clamping piece 31; and / or, the second clamping piece 32 is connected to the baffle 34 at both opposite ends along its length direction, and the baffle 34 extends in the direction close to the first clamping piece 31 to exceed the second clamping piece 32.

[0048] In actual application, the baffles 34 connected to both ends of the first clamping piece 31 along the length direction effectively prevent the capacitor from moving laterally and enhance the clamping stability. The baffles 34 extend beyond the clamping piece to form a protective barrier, ensuring that the capacitor does not deviate during high-speed rotation, further improving the safety and reliability of the device. The baffles 34 are simple in design, easy to install, low in maintenance cost, and optimize overall production efficiency. The baffles 34 can also be designed at both ends of the second clamping piece 32 for two-way protection to ensure that the capacitor is fixed in all directions.

[0049] As can be understood, in order to ensure that the baffle 34 does not hinder the entry and exit of the capacitor 40, the baffle 34 is gradually extended in an inclined direction away from the capacitor 40 along the direction approaching the roller rack 2. Taking the first clamping piece 31 and the second clamping piece 32 as an example, along the direction approaching the roller rack 2, the distance between the baffle 34 of the first clamping piece 31 and the baffle 34 of the second clamping piece 32 becomes larger and larger. When the first clamping piece 31 and the second clamping piece 32 move away from each other, the baffle 34 will rotate relative to the roller rack 2. Therefore, the distance between the two baffles 34 close to the roller rack 2 end will be shortened, and the distance between the two baffles 34 away from the roller rack 2 end will increase. Therefore, the baffle 34 is extended in an inclined direction. The distance between the baffle 34 of the first clamping piece 31 and the baffle 34 of the second clamping piece 32 can be expanded along the direction approaching the roller rack 2, thereby avoiding the baffle 34 blocking the entry and exit of the capacitor 40 when the clamping assembly 3 is opened.

[0050] See again Figure 4 The impregnation cylinder 10 includes an elastic member 4 , and an elastic member 4 is connected between two adjacent clamping assemblies 3 . The elastic member 4 is used to push the first clamping piece 31 and the second clamping piece 32 closer to each other.

[0051] In practice, the elastic member 4 is positioned between two adjacent clamping assemblies 3. The two adjacent elastic members 4 push the first clamping piece 31 and the second clamping piece 32 toward each other, creating a stable clamping force. The elastic member 4 automatically adjusts its tightness during high-speed rotation of the rolling frame 2, ensuring the capacitor is always optimally clamped. This effectively mitigates vibration and impact under various operating conditions, further enhancing the stability and durability of the device.

[0052] See again Figure 3 The first clamping piece 31 includes a first main body portion 311 and a first connecting portion 312, the first main body portion 311 and the first connecting portion 312 are connected, the first connecting portion 312 is rotatably connected to the roller frame 2, and the first connecting portion 312 is provided with a first tooth portion 313 on the side facing the second clamping piece 32; the second clamping portion includes a second main body portion 321 and a second connecting portion 322, the second main body portion 321 and the second connecting portion 322 are connected, the second connecting portion 322 is rotatably connected to the roller frame 2, and the second connecting portion 322 is provided with a second tooth portion 323 on the side facing the first clamping piece 31, and the first tooth portion 313 and the second tooth portion 323 are engaged.

[0053] In practice, the first clamping piece 31 comprises a first main portion 311 and a first connecting portion 312. The first connecting portion 312 is rotatably connected to the roller frame 2 to ensure flexible adjustment. A first tooth portion 313 is provided on the side of the first connecting portion 312 facing the second clamping piece 32. This first tooth portion 313 precisely engages with the second tooth portion 323 of the second clamping piece 32, forming a secure mechanical locking structure. This enhances the stability and durability of the clamping system, effectively preventing loosening and displacement of the capacitor during high-speed operation, and improving the overall performance of the device.

[0054] The roller rack 2 is provided with a plurality of placement racks 21 along its circumference. The first connection part 312 and the second connection part 322 are both rotatably connected to the ends of the placement rack 21. The capacitor 40 is placed on the placement rack 21. In this way, when the first clamping piece 31 and the second clamping piece 32 are opened away from each other, the capacitor 40 will not fall over.

[0055] See again Figure 4 The first clamping piece 31 includes a first supporting portion 314, which is connected to the first connecting portion 312 and is located above the first tooth portion 313; the second clamping piece 32 includes a second supporting portion 324, which is connected to the second connecting portion 322 and is located above the second tooth portion 323. The first supporting portion 314 and the second supporting portion 324 are arranged relative to each other.

[0056] In actual application, the first supporting portion 314 and the second supporting portion 324 are arranged at a relative interval. The first supporting portion 314 and the second supporting portion 324 mainly provide a position. When the operator inserts the opening member 51 between the first supporting portion 314 and the second supporting portion 324, the opening member 51 will push open the first supporting portion 314 and the second supporting portion 324, so that the first clamping piece 31 and the second clamping piece 32 rotate in a direction away from each other, which is convenient for opening the first clamping piece 31 and the second clamping piece 32, and facilitates the rapid installation and replacement of the capacitor.

[0057] See Figure 5 The impregnation cylinder 10 includes a push-up assembly 5, which includes a power member and a push-up member 51. The driving end of the power member is connected to the push-up member 51 and pushes the push-up member 51 to be inserted between the first supporting portion 314 and the second supporting portion 324, so that the first clamping piece 31 and the second clamping piece 32 rotate in a direction of separation from each other.

[0058] In practical applications, the power element can be mounted on the frame 20, with the driving end of the power element connected to the push-opening element 51. By controlling the movement of the power element, the position of the push-opening element 51 can be precisely adjusted to ensure smooth separation of the first clamping piece 31 and the second clamping piece 32, simplifying the installation and replacement process of the capacitor element and improving operational efficiency and safety. The power element can be a motor or other structure.

[0059] See again Figure 3 The first clamping piece 31 and / or the second clamping piece 32 is provided with a through hole 315.

[0060] In practical applications, the first clamping piece 31 is provided with a through hole 315 to facilitate heat dissipation and reduce weight. The through hole 315 design optimizes the airflow channel, effectively reducing the operating temperature of the capacitor, extending its service life, and improving the reliability and stability of the overall device. In addition, the through hole 315 allows the clamping status of the capacitor to be observed, facilitating real-time monitoring and maintenance. The second clamping piece 32 can also be provided with a through hole 315 to achieve symmetrical heat dissipation and further reduce the overall weight.

[0061] See again Figure 2 The impregnation cylinder 10 includes a cover plate 6, a locking assembly 7 and a driving member 8. The cover plate 6 is arranged above the cylinder body 1. The driving end of the driving member 8 is connected to the cover plate 6. The locking assembly 7 is connected to the cover plate 6. The cylinder body 1 is provided with a locking portion 11; the driving member 8 drives the cover plate 6 to be covered on the cylinder body 1, and the locking assembly 7 is connected to the locking portion 11 to fix the cover plate 6 to the cylinder body 1.

[0062] In practice, once the impregnation cylinder 10 is filled with capacitors, the driver 8 drives the cover 6 to close against the cylinder 1. The locking assembly 7 automatically engages the locking portion 11, ensuring a secure seal on the cover 6 and preventing leakage of the immersion liquid. Simultaneously, the driver 8 precisely controls the opening and closing speed of the cover 6 to avoid impact on the capacitors and ensure safe and stable operation.

[0063] The present application also provides an impregnation method, which uses the above-mentioned impregnation equipment and includes the following steps:

[0064] S1, baking the material to be impregnated;

[0065] S2, the impregnation cylinder moves to the second station, and the loading mechanism transports the baked material to the impregnation cylinder on the second station;

[0066] S3, the impregnation cylinder on the second station is filled with material and moves to the first station; another impregnation cylinder moves to the second station, and the loading mechanism transports the baked material to the impregnation cylinder on the second station. The impregnation cylinder on the second station is filled with material and moves to the first station, and the cycle continues until all impregnation cylinders are filled with material and move to the first station;

[0067] S4, after the impregnation cylinder to be moved to the first station impregnates the material for a preset time, the impregnation cylinder is drained, and the drained impregnation cylinder is moved again to the second station, and the loading mechanism takes the impregnated material from the impregnation cylinder at the second station and puts the unimpregnated material into the impregnation cylinder;

[0068] S5. Repeat the above steps until all materials have completed the impregnation process.

[0069] In specific implementation, the capacitor is first placed in the baking mechanism for baking. Then, the clamping plate of the loading mechanism removes the capacitor from the baking mechanism and places it in the designated position. The clamping plate is released, and at the same time, one of the multiple impregnation cylinders moves to the second station. At this time, the push block is activated to push the capacitor into the impregnation cylinder. After the impregnation cylinder is filled with capacitors, it moves to the first station for impregnation. Another impregnation cylinder moves to the second station to wait for loading, and the cycle continues.

[0070] After the first impregnation cylinder completes its impregnation process, it moves to the second station. The loading mechanism grips a new capacitor and places it in the designated position. The cylinder opens, revealing the already impregnated capacitor. The loading mechanism then pushes the new capacitor into the cylinder and pushes the already impregnated capacitor out of the cylinder for subsequent processing. This entire cycle achieves highly efficient capacitor impregnation, while ensuring safe and stable equipment operation and significantly improving production efficiency.

[0071] Different from the prior art, the embodiment of the present application provides an impregnation cylinder 10, an impregnation device, and an impregnation method. The impregnation cylinder 10 includes a cylinder body 1, a roller 2, and a clamping assembly 3. The roller 2 is rotatably connected to the cylinder body 1; the roller 2 is connected to multiple clamping assemblies 3 along its circumference; wherein the clamping assembly 3 includes a first clamping piece 31 and a second clamping piece 32, both of which are rotatably connected to the roller 2. The end of the first clamping piece 31 away from the roller 2 extends obliquely toward the direction closer to the second clamping piece 32, and the end of the second clamping piece 32 away from the roller 2 extends obliquely toward the direction closer to the first clamping piece 31. Compared with the prior art, the clamping assembly 3 of the present application adopts an inclined design, which effectively solves the stability problem of the capacitor during the impregnation process, improves the uniformity of impregnation, reduces the defective rate, and ensures the stability of product quality. The multiple clamping assemblies 3 are at the same distance from the central axis of the roller 2, ensuring that each capacitor is evenly stressed during rotation and avoiding the problem of uneven impregnation caused by eccentricity. The use of such an impregnation device containing an impregnation cylinder 10 not only improves production efficiency, but also significantly reduces maintenance costs, realizes an efficient and stable production process, and further enhances the market competitiveness of the product.

[0072] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
