[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] See Figure 1 This application provides an impregnation device, including an impregnation cylinder 10, a feeding mechanism 30, and a frame 20. The frame 20 has a first station 201 and a second station 202. The feeding mechanism 30 is slidably disposed relative to the frame 20. Multiple impregnation cylinders 10 are provided, and each cylinder is slidably connected to the frame 20. Each cylinder can selectively slide to either the first station 201 or the second station 202. The feeding mechanism 30 is used to remove and / or place materials into the impregnation cylinder 10 located at the second station 202. In this embodiment, a capacitor 40 is used as an example of the material.

[0031] In practical applications, this impregnation equipment typically consists of multiple impregnation cylinders 10, a sliding track, a drive unit, a loading mechanism 30, and a frame 20. During operation, the loading mechanism 30 first loads the capacitors to be impregnated into the impregnation cylinder 10 located at the second station 202. Then, the drive unit starts, moving the impregnation cylinder 10 along the sliding track to the first station 201. Simultaneously, another impregnation cylinder 10 moves to the second station 202 to load capacitors. At the first station 201, the capacitors in the impregnation cylinders 10 undergo impregnation for a period of time. After processing, the impregnation cylinder 10 is again driven by the drive unit to move along the sliding track to the second station 202. At the second station 202, the loading mechanism 30 removes the impregnated capacitors for further processing. Thus, through the reciprocating movement of the impregnation cylinders 10 on the sliding track, continuous processing and efficient production of capacitors are achieved.

[0032] The sliding connection of the impregnation cylinder 10 ensures operational flexibility and improves the efficiency of capacitor processing. The impregnation cylinder 10 can slide between the first station 201 and the second station 202, meaning that while one impregnation cylinder 10 is performing the impregnation process, another impregnation cylinder 10 can be loading or unloading materials. This parallel operation significantly shortens the production cycle and improves overall production efficiency. The sliding design of the impregnation cylinder 10 allows multiple impregnation cylinders 10 to share a single feeding mechanism 30, thereby reducing the structural complexity of the equipment and minimizing the footprint. The feeding mechanism 30 can be implemented using a robotic arm or similar device.

[0033] See Figure 2 The impregnation cylinder 10 includes a cylinder body 1, a roller frame 2, and a clamping assembly 3. The roller frame 2 is rotatably connected to the cylinder body 1. Multiple clamping assemblies 3 are connected to the roller frame 2 along its circumference, and the multiple clamping assemblies 3 are at the same distance from the central axis of the roller frame 2. The clamping assembly 3 includes a first clamping piece 31 and a second clamping piece 32. Both the first clamping piece 31 and the second clamping piece 32 are rotatably connected to the roller frame 2. The end of the first clamping piece 31 away from the roller frame 2 extends obliquely toward the second clamping piece 32, and the end of the second clamping piece 32 away from the roller frame 2 extends obliquely toward the first clamping piece 31.

[0034] In practical applications, the clamping assembly 3 includes a first clamping piece 31 and a second clamping piece 32. Both the first clamping piece 31 and the second clamping piece 32 are connected to the roller frame 2. The first clamping piece 31 is designed to be inclined towards the second clamping piece 32, and the second clamping piece 32 is inclined towards the first clamping piece 31. Along 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 pieces and the capacitor 40, thereby improving the clamping stability. This application ensures that the capacitor is firmly fixed during the impregnation process through the inclined design, preventing slippage. The rotating connection of the roller frame 2 allows the capacitor to be evenly impregnated, improving the impregnation effect.

[0035] The distances from the central axis of the roller frame 2 to the multiple clamping components 3 are the same, ensuring that each capacitor is subjected to uniform force during rotation and avoiding uneven impregnation caused by eccentricity. At the same time, this symmetrical layout simplifies the mechanical structure, reduces manufacturing costs, improves the stability of equipment operation, and further enhances the overall performance of the production line.

[0036] Compared to existing technologies, the clamping assembly 3 of this application adopts an inclined design, which effectively solves the stability problem of capacitors during the impregnation process, improves impregnation uniformity, reduces the defect rate, and ensures the stability of product quality. The distances from multiple clamping assemblies 3 to the central axis of the roller frame 2 are the same, ensuring that each capacitor is subjected to uniform force during rotation and avoiding uneven impregnation caused by eccentricity.

[0037] See Figure 3 The first clamping piece 31 has a plurality of elastic protrusions 33 on the side facing the second clamping piece 32, and / or the second clamping piece 32 has a plurality of elastic protrusions 33 on the side facing the first clamping piece 31.

[0038] In practical applications, the first clamping piece 31 has multiple elastic protrusions 33 on the side facing the second clamping piece 32. These elastic protrusions 33 increase the clamping force, ensuring the capacitor does not detach during high-speed rotation and improving safety. The design of the elastic protrusions 33 also adapts to capacitors of different sizes, enhancing the versatility of the device and further optimizing the production process. The elastic protrusions 33 ensure clamping stability while avoiding excessive pressure on the capacitor, thus extending its service life.

[0039] Understandably, the second clamping piece 32 also has multiple 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.

[0040] See Figure 6 The aforementioned 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 abut against the material. The peripheral surface 333 is connected to the supporting surface 332 and the connecting surface 331 respectively. The peripheral surface 333 at least partially contracts towards the supporting surface 332.

[0041] In practical applications, the elastic protrusion 33 includes a connecting surface 331, a supporting surface 332, and a peripheral surface 333. The connecting surface 331 is tightly coupled with the first clamping piece 31 or the second clamping piece 32, and the supporting surface 332 precisely fits against the surface of the capacitor to ensure stable clamping. The constricted design of the peripheral surface 333 increases elasticity, effectively buffers vibration, and prevents damage to the capacitor. The supporting surface 332 adopts a planar structure to ensure maximum contact area with the capacitor, improving the uniformity and stability of clamping.

[0042] See Figure 4 The clamping assembly 3 includes baffles 34. The first clamping piece 31 is connected to baffles 34 at both ends along its length direction. The baffles 34 extend in a direction close to the second clamping piece 32 beyond the first clamping piece 31. And / or, the second clamping piece 32 is connected to baffles 34 at both ends along its length direction. The baffles 34 extend in a direction close to the first clamping piece 31 beyond the second clamping piece 32.

[0043] In practical applications, the baffles 34 connected to both ends of the first clamping plate 31 along its length effectively prevent lateral movement of the capacitor, enhancing clamping stability. The baffles 34 extend beyond the clamping plate, forming a protective barrier to ensure the capacitor does not shift during high-speed rotation, further improving the safety and reliability of the device. The baffles 34 have a simple design, are easy to install, have low maintenance costs, and optimize overall production efficiency. The second clamping plate 32 can also have baffles 34 designed at both ends, providing bidirectional protection and ensuring the capacitor is fixed in all directions.

[0044] Understandably, in order to ensure that the baffle 34 does not obstruct the entry and exit of the capacitor 40, the baffle 34 gradually extends at an angle away from the capacitor 40 along the direction close to the roller frame 2. Taking the example of both the first clamping plate 31 and the second clamping plate 32 being provided with baffle 34, along the direction close to the roller frame 2, the distance between the baffle 34 of the first clamping plate 31 and the baffle 34 of the second clamping plate 32 becomes larger and larger. When the first clamping plate 31 and the second clamping plate 32 move away from each other, the baffle 34 will rotate relative to the roller frame 2. Therefore, the distance between the two baffles 34 near the end of the roller frame 2 will shorten, and the distance between the two baffles 34 away from the roller frame 2 will increase. Therefore, by extending the baffle 34 at an angle along the direction close to the roller frame 2, the distance between the baffle 34 of the first clamping plate 31 and the baffle 34 of the second clamping plate 32 can be increased, thereby preventing the baffle 34 from blocking the entry and exit of the capacitor 40 when the clamping assembly 3 is opened.

[0045] See again Figure 4 The impregnation cylinder 10 includes an elastic element 4, and an elastic element 4 is connected between two adjacent clamping assemblies 3. The elastic element 4 is used to push the first clamping piece 31 and the second clamping piece 32 closer to each other.

[0046] In practical applications, the elastic element 4 is positioned between two adjacent clamping components 3. The two adjacent elastic elements 4 respectively push the first clamping piece 31 and the second clamping piece 32 closer together, forming a stable clamping force. The elastic element 4 can automatically adjust its tightness when the roller frame 2 rotates at high speed, ensuring that the capacitor is always in the optimal clamping state, effectively coping with vibration and impact under different working conditions, and further improving the stability and durability of the device.

[0047] See again Figure 3The first clamping piece 31 includes a first main body 311 and a first connecting part 312. The first main body 311 and the first connecting part 312 are connected. The first connecting part 312 is rotatably connected to the roller frame 2. The first connecting part 312 is provided with a first tooth 313 on the side facing the second clamping piece 32. The second clamping piece includes a second main body 321 and a second connecting part 322. The second main body 321 and the second connecting part 322 are connected. The second connecting part 322 is rotatably connected to the roller frame 2. The second connecting part 322 is provided with a second tooth 323 on the side facing the first clamping piece 31. The first tooth 313 and the second tooth 323 mesh with each other.

[0048] In practical applications, the first clamping piece 31 includes a first main body 311 and a first connecting part 312. The first connecting part 312 is rotatably connected to the roller frame 2 to ensure flexible adjustment. The first connecting part 312 has a first tooth 313 on the side facing the second clamping piece 32, which precisely meshes with the second tooth 323 of the second clamping piece 32 to form a robust mechanical locking structure. This enhances the stability and durability of the clamping system, effectively prevents the capacitor from loosening and shifting during high-speed operation, and improves the overall performance of the device.

[0049] The roller frame 2 is provided with multiple placement racks 21 along its circumference. The first connecting part 312 and the second connecting part 322 are rotatably connected to the end 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 move away from each other and open, the capacitor 40 will not tip over.

[0050] See again Figure 4 The first clamping piece 31 includes a first supporting portion 314, which is connected to a first connecting portion 312 and is located above the first toothed portion 313; the second clamping piece 32 includes a second supporting portion 324, which is connected to a second connecting portion 322 and is located above the second toothed portion 323, with the first supporting portion 314 and the second supporting portion 324 being arranged at a distance from each other.

[0051] In practical applications, the first supporting part 314 and the second supporting part 324 are arranged at a distance from each other. The first supporting part 314 and the second supporting part 324 mainly provide a position. When the operator inserts the opening member 51 between the first supporting part 314 and the second supporting part 324, the opening member 51 will open the first supporting part 314 and the second supporting part 324, so that the first clamping piece 31 and the second clamping piece 32 rotate in a direction away from each other, which makes it easy to open the first clamping piece 31 and the second clamping piece 32, and facilitates the quick installation and replacement of the capacitor.

[0052] See Figure 5The immersion cylinder 10 includes a push-opening assembly 5, which includes a power member and a push-opening member 51. The drive end of the power member is connected to the push-opening member 51 and pushes the push-opening member 51 to be inserted between the first support portion 314 and the second support portion 324, so that the first clamping piece 31 and the second clamping piece 32 rotate in a direction that separates them from each other.

[0053] In practical applications, the power unit can be mounted on the frame 20. The drive end of the power unit is connected to the top opening member 51. By controlling the movement of the power unit, the position of the top opening member 51 can be precisely adjusted to ensure the smooth separation of the first clamping piece 31 and the second clamping piece 32. This simplifies the installation and replacement process of the capacitor component and improves operational efficiency and safety. The power unit can be a motor or similar structure.

[0054] See again Figure 3 The first clamping piece 31 and / or the second clamping piece 32 are provided with through holes 315.

[0055] In practical applications, the first clamping plate 31 has a through hole 315 to facilitate heat dissipation and reduce weight. The through hole 315 optimizes the airflow channel, effectively reducing the operating temperature of the capacitor, extending its service life, and improving the overall reliability and stability of the device. Furthermore, the through hole 315 allows observation of the capacitor's clamping status, facilitating real-time monitoring and maintenance. The second clamping plate 32 can also have a through hole 315 to achieve symmetrical heat dissipation and further reduce the overall weight.

[0056] 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 disposed 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 part 11. The driving member 8 drives the cover plate 6 to cover the cylinder body 1, and the locking assembly 7 is connected to the locking part 11 to fix the cover plate 6 to the cylinder body 1.

[0057] In practical applications, after the immersion tank 10 is filled with capacitors, the drive unit 8 drives the cover plate 6 to close within the tank body 1, and the locking assembly 7 automatically engages the locking part 11, ensuring that the cover plate 6 is firmly sealed and preventing leakage of the immersion liquid. At the same time, the drive unit 8 precisely controls the opening and closing speed of the cover plate 6 to avoid impacting the capacitors and ensure safe and stable operation.

[0058] See Figure 7 The feeding mechanism 30 may include a fixed plate 301, a pusher 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 pusher block 303 is movably connected to the fixed plate 301 and is used to push the material between the two clamping plates 302 into the clamping member of the impregnation cylinder.

[0059] In practical applications, after the capacitor 40 in the impregnation cylinder has been impregnated, it is necessary to remove the capacitor 40 and put in a new capacitor 40 to be impregnated. Therefore, the moving mechanism of this application is provided with a pusher 303. After the capacitor 40 in the impregnation cylinder has been impregnated, the impregnation cylinder moves to the second station again. The second station has a strip groove on one side. The upper end of the strip groove and the end near the impregnation cylinder have openings. A row of capacitors 40 can be put into the strip groove. The pusher 303 can push the row of capacitors 40 from the other end of the strip groove, so that the row of capacitors 40 is pushed out from the opening at the end near the impregnation cylinder and enters the clamping assembly of the impregnation cylinder. In practical applications, firstly, two clamping plates 302 clamp the capacitor component 40 to be impregnated and move it to a designated position (strip groove). The two clamping plates 302 then open relative to each other, releasing the clamped capacitor component 40 and placing it in the strip groove. After the impregnation cylinder opens to expose the impregnated capacitor component 40, the pusher block 303 moves, pushing the capacitor component 40 between the clamping plates 302 and located in the strip groove out of the opening and sequentially pushing it into the clamping assembly within the impregnation cylinder. Simultaneously, the new capacitor component 40 can sequentially expel a row of capacitor components 40 corresponding to the clamping assembly in the impregnation cylinder to a slot on the other side of the impregnation cylinder (e.g., a movable discharge trough, which can connect to the second opening of the clamping assembly), thus realizing the placement of the capacitor component 40 to be impregnated and the removal of the impregnated capacitor component 40. This ensures the continuity and automation of the entire impregnation process. No multiple steps are required; the pusher block 303 can simultaneously realize the placement and removal of the capacitor component, greatly simplifying the operation and improving work efficiency.

[0060] Unlike existing technologies, this application provides an impregnation cylinder 10 and an impregnation device. The impregnation cylinder 10 includes a cylinder body 1, a roller frame 2, and clamping components 3. The roller frame 2 is rotatably connected to the cylinder body 1. Multiple clamping components 3 are connected to the roller frame 2 circumferentially, and the distances from the multiple clamping components 3 to the central axis of the roller frame 2 are the same. Each clamping component 3 includes a first clamping piece 31 and a second clamping piece 32, both of which are rotatably connected to the roller frame 2. The end of the first clamping piece 31 away from the roller frame 2 extends obliquely towards the second clamping piece 32, and the end of the second clamping piece 32 away from the roller frame 2 extends obliquely towards the first clamping piece 31. Compared to existing technologies, the clamping component 3 of this application adopts an oblique design, effectively solving the stability problem of capacitor components during the impregnation process, improving impregnation uniformity, reducing the defect rate, and ensuring product quality stability. The distances from multiple clamping components 3 to the central axis of the roller frame 2 are the same, ensuring that each capacitor component is subjected to uniform force during rotation and avoiding uneven impregnation caused by eccentricity. The impregnation equipment using this type of impregnation cylinder 10 not only improves production efficiency but also significantly reduces maintenance costs, achieving a highly efficient and stable production process and further enhancing the product's market competitiveness.

[0061] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
