[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 used to limit the present invention.

[0051] See also Figure 1The embodiment of the present application provides an impregnation device for impregnating capacitor components. The impregnation device includes a frame 1, a first feeding mechanism 4 and an impregnation mechanism 5. The frame 1 is provided with a first station 11 and a second station 12; the first feeding mechanism 4 is slidably arranged relative to the frame 1; the impregnation mechanism 5 includes at least two impregnation cylinders 51, which are slidably connected to the frame 1. The impregnation cylinders 51 can selectively slide to the first station 11 or the second station 12. The first feeding mechanism 4 is arranged above the second station 12, and is used to take out and / or put in materials from the impregnation cylinder 51 located at the second station 12.

[0052] In practical applications, there are multiple impregnation cylinders 51, each of which is slidably connected to the frame 1, and each of which can selectively slide to the first station 11 or the second station 12. When the impregnation cylinder 51 slides to the second station 12, since the first loading mechanism 4 is slidably connected to the frame 1, and the first loading mechanism 4 is arranged above the second station 12, the first loading mechanism 4 can transport the baked capacitor to the impregnation cylinder 51 located at the second station 12. After the impregnation cylinder 51 is filled with capacitors, the impregnation cylinder 51 slides to the first station 11 for impregnation. At this time, another impregnation cylinder 51 slides to the second station 12, waiting for the first loading mechanism 4 to load capacitors into it, and the operation is cyclically performed until all the impregnation cylinders 51 are filled with capacitors. And when the impregnation cylinder 51 impregnates the capacitors for a preset time, the impregnation cylinder 51 moves to the second station 12 again, and the first loading mechanism 4 transports the impregnated capacitors to the next process.

[0053] It is understandable that the first feeding mechanism 4 can adopt a structure such as a robot or a robot arm. The robot is an automatic operating device that can imitate certain movement functions of human hands and arms to grasp, carry objects or operate tools according to a fixed procedure.

[0054] Compared with the prior art, the multiple impregnation cylinders 51 of the present application share a first loading mechanism 4, which reduces the complexity of the structure and the space occupied by the device. At the same time, the multiple impregnation cylinders 51 are loaded in sequence. When the next impregnation cylinder 51 is loading the capacitor, the previous impregnation cylinder 51 is performing the impregnation process of the capacitor. The loading process and the impregnation process are performed simultaneously, which improves the impregnation efficiency; and after the impregnation is completed, the impregnation cylinder 51 moves to the second workstation 12 again, and the first loading mechanism 4 takes out the impregnated capacitor. The entire loading and taking processes can be completed by the first loading mechanism 4, which effectively reduces structural components and reduces equipment costs.

[0055] It should be noted that the materials impregnated by the device include but are not limited to capacitors, and in other embodiments, it can also be used to impregnate other materials.

[0056] See also Figure 2The impregnation device includes a first guide rail 8, which is arranged on a frame 1; a first feeding mechanism 4 is slidably connected to the first guide rail 8, a plurality of impregnation cylinders 51 are respectively arranged on opposite sides of the first guide rail 8, a second station 12 is arranged below the first guide rail 8, and at least one first station 11 is respectively arranged on both sides of each second station 12. At least two second stations 12 can be arranged along the length direction of the first guide rail 8. Figure 2 As shown, there are two second workstations 12 and four impregnation cylinders 51 (2X2 layout). Figure 3 As shown, three second workstations 12 are provided, and six impregnation cylinders 51 are provided (3X2 layout). Of course, the number of second workstations 12 and the number and arrangement of impregnation cylinders 51 can also be set according to actual conditions.

[0057] In practical applications, the first guide rail 8 is arranged above the second station 12, the first feeding mechanism 4 is slidably connected to the first guide rail 8, the first station 11 is arranged on both sides of the second station 12, and the plurality of impregnation cylinders 51 can be symmetrically arranged on opposite sides of the first guide rail 8. In the initial state, the impregnation cylinder 51 can be located at the first station 11, and when it is necessary to load or take out materials, the impregnation cylinder 51 slides to the second station 12, so that the first feeding mechanism 4 can load or take out materials. Such a setting can reasonably utilize space and reduce the volume of the device.

[0058] In a specific application, a second guide rail 13 is provided on the frame 1, and the second guide rail 13 is vertically arranged below the first guide rail 8. The first station 11 and the second station 12 are arranged along the second guide rail 13, and the second guide rail 13 can be arranged in pairs. At least two slides are provided on the second guide rail 13, and each impregnation cylinder 51 can be seated on the slide. The slide is connected to a driving component for driving the slide to slide from the first station 11 to the second station 12 along the second guide rail 13 or to return from the second station 12 to the first station 11.

[0059] See also Figure 3 The impregnation equipment also includes a protection mechanism 7, which is movably arranged on the frame 1; when the impregnation cylinder 51 is located at the second station 12, and during the interval period when the first feeding mechanism 4 moves the materials out in batches, the protection mechanism 7 is covered on the impregnation cylinder 51.

[0060] In practical applications, if the capacitor components are exposed for too long after impregnation, the quality of the capacitor components may be easily affected. Therefore, the present application provides a protective mechanism 7. When the impregnation cylinder 51 slides to the second station 12 and the first feeding mechanism 4 is not picking up / loading materials, the protective mechanism 7 is covered on the impregnation cylinder 51 to close the impregnation cylinder 51 and prevent the capacitor components inside the impregnation cylinder 51 from being exposed to the outside. When the first feeding mechanism 4 is picking up / loading materials, the protective mechanism 7 can open the impregnation cylinder 51 to facilitate the first feeding mechanism 4 to pick up / load materials.

[0061] Specifically, the protection mechanism 7 may include two protection covers 72, and the two protection covers 72 are symmetrically arranged on both sides of the impregnation cylinder 51, each protection cover 72 is connected to a third driving member 73 and a fourth driving member 74, the third driving member 73 is used to push the two protection covers 72 close to the impregnation cylinder 51 so that the two protection covers 72 can be covered on the impregnation cylinder 51, and the fourth driving member 74 is used to push the two protection covers 72 close to each other so that the two protection covers 72 can fit together to close the impregnation cylinder 51 and avoid exposure of the capacitor; when the first feeding mechanism 4 takes / feeds materials, the two protection covers 72 separate from each other to form a first feeding port 71 to facilitate the first feeding mechanism 4 to take out / load the capacitor.

[0062] It should be noted that, during normal operation, only the third driving member 73 can be started, that is, the two protective covers 72 are only covered on the impregnation cylinder 51, and the two protective covers 72 are separated to expose the first loading port 71, so as to facilitate the first loading mechanism 4 to load / take materials. Since the first loading mechanism 4 needs to load / take materials multiple times, relative to the closed mode of the two protective covers 72, the separation of the two protective covers 72 can improve the loading / taking efficiency of the first loading mechanism 4; and the first loading port 71 can be set to be smaller, exposing only a row of materials to be taken out or loaded in the impregnation cylinder 51, which can also achieve the effect of reducing the exposure time of the capacitor.

[0063] See also Figure 4 and Figure 5 The impregnation cylinder 51 includes a cylinder body 511, a roller frame 512 and a first elastic member 513. The roller frame 512 is rotatably arranged in the cylinder body 511. The roller frame 512 is provided with a plurality of clamping members 514 along its circumference, and a first elastic member 513 is provided between two adjacent clamping members 514. The clamping members 514 include a first clamping piece 5141 and a second clamping piece 5142. The first elastic member 513 pushes the first clamping piece 5141 and the second clamping piece 5142 to clamp each other. Each set of the first clamping piece 5141 and the second clamping piece 5142 can clamp a plurality of capacitors.

[0064] In actual application, the roller rack 512 is rotatably connected to the cylinder body 511, and the roller rack 512 is provided with a plurality of clamping members 514 along its circumference, and the clamping members 514 are used to clamp the capacitor. When loading or removing materials, the cylinder body 511 moves to the second workstation 12, and the protective mechanism 7 cover is arranged on the cylinder body 511. The roller rack 512 rotates a preset angle so that one of the plurality of clamping members 514 is exposed at the first loading port 71, so as to facilitate the first loading mechanism 4 to load / remove materials. After one of the clamping members 514 has finished loading / removing materials, the roller rack 512 continues to rotate so that the plurality of clamping members 514 are exposed at the first loading port 71 in turn, and the plurality of clamping members 514 are removed / loaded in turn. Such a setting can improve the loading / removing efficiency, and at the same time reduce the time that the capacitor is exposed to the first loading port 71, thereby improving the impregnation quality of the capacitor. The impregnation cylinder 51 is provided with a rotating drive member for driving the roller 512. The rotating drive member can drive the roller 512 to rotate step by step, so that each clamping member 514 rotates to the bottom of the first loading port 71 in sequence, so as to facilitate loading / unloading in sequence. The rotating drive member may include a motor (such as a stepping motor, etc.) and a transmission mechanism, and the transmission mechanism may be a chain transmission or a gear transmission mechanism. The roller 512 is evenly provided with N clamping members 514 along the circumference. The angle of each rotation of the roller 512 can be A, and A is equal to 360 / N. For example, when there are 12 clamping members 514, the angle of each rotation of the roller 512 is 30 degrees.

[0065] At the same time, in order to improve the clamping stability of the clamping member 514 on the capacitor, a first elastic member 513 is connected between adjacent clamping members 514. When the capacitor is placed between the first clamping plate 5141 and the second clamping plate 5142, the first elastic member 513 pushes the first clamping plate 5141 and the second clamping plate 5142 to clamp together to prevent the capacitor from falling.

[0066] See also Figure 6 and Figure 7 The impregnation mechanism 5 also includes a push-up component 52, which includes a first driving member 521 and a push-up component 522. The first clamping piece 5141 and the second clamping piece 5142 are both rotatably connected to the roller frame 512. The driving end of the first driving member 521 is connected to the push-up component 522 and pushes the push-up component 522 to be inserted between the first clamping piece 5141 and the second clamping piece 5142 to separate the first clamping piece 5141 and the second clamping piece 5142.

[0067] In practical applications, the push-up assembly 52 is arranged opposite to the second station 12, and the push-up assembly 52 can be arranged on both sides of the (each) second station 12 along the direction of the first guide rail 8 through a support frame, without affecting the movement of the impregnation cylinder 51 between the first station 11 and the second station 12. When the impregnation cylinder 51 moves to the second station 12, the push-up assembly 52 is used to separate the first clamping piece 5141 and the second clamping piece 5142, so that the first feeding mechanism 4 can load / remove materials. Specifically, the opening assembly 52 includes a first driving member 521 and an opening member 522. When the roller 512 rotates the clamping member 514 to the first loading port 71, the first driving member 521 drives the opening member 522 to extend between the first clamping piece 5141 and the second clamping piece 5142. The first clamping piece 5141 and the second clamping piece 5142 are supported by the opening member 522 and rotate in a direction away from each other, so that the clamping member 514 is opened, and then the first loading mechanism 4 can take out the capacitor, or put the capacitor into the clamping member 514. After the first loading mechanism 4 has finished loading / retrieving materials, the first driving member 521 drives the opening member 522 to retract, and the first elastic member 513 pushes the first clamping piece 5141 and the second clamping piece 5142 to approach each other, so that the clamping member 514 returns to its original state.

[0068] In one embodiment, the first clamping piece 5141 and the second clamping piece 5142 may be provided with meshing teeth. When the first clamping piece 5141 and the second clamping piece 5142 are clamped with each other, the two are meshed with each other through the meshing teeth, which can further improve the clamping stability of the first clamping piece 5141 and the second clamping piece 5142.

[0069] See also Figure 8 The impregnation mechanism 5 includes an impregnation cover plate 53, a locking assembly 54 and a second driving member 55. The impregnation cover plate 53 is arranged above the impregnation cylinder 51. The driving end of the second driving member 55 is connected to the impregnation cover plate 53. The locking assembly 54 is connected to the impregnation cover plate 53. The impregnation cylinder 51 is provided with a locking portion 515. The second driving member 55 drives the impregnation cover plate 53 to cover the impregnation cylinder 51, and the locking assembly 54 is connected to the locking portion 515 to fix the impregnation cover plate 53 to cover the impregnation cylinder 51.

[0070] In practical applications, after the impregnation cylinder 51 is loaded, the impregnation cylinder 51 slides to the first station 11 for impregnation. At this time, the impregnation cover plate 53 needs to be covered on the impregnation cylinder 51 to ensure that the impregnation cylinder 51 is in a closed state. Specifically, the second driving member 55 is arranged on the frame 1, and the output end of the second driving member 55 is connected to the impregnation cover plate 53. The second driving member 55 drives the impregnation cover plate 53 to cover the impregnation cylinder 51. At the same time, the locking assembly 54 is connected to the locking part 515, so that the impregnation cover plate 53 and the impregnation cylinder 51 are fixedly covered together.

[0071] Specifically, the locking assembly 54 includes a fifth driving member 541, a locking head 542 and a locking tooth 543. The impregnation cylinder 51 is provided with a plurality of locking portions 515 along its circumference. The locking teeth 543 are rotatably connected to the impregnation cover plate 53. The positions and numbers of the locking teeth 543 and the locking portions 515 are relative. The locking head 542 is connected to one end of the locking tooth 543 close to the impregnation cylinder 51. The plurality of locking teeth 543 are sequentially connected together by a chain.

The second loading port 311 is used for allowing the first loading mechanism 4 to extend into the baking mechanism 3.

[0073] In practical applications, the capacitor needs to be baked before impregnation to remove the surface moisture of the capacitor, avoid affecting the impregnation effect, and improve the penetration of the impregnation liquid. Based on this, the present application sets a baking mechanism 3, which includes a first baking part 31 and a second baking part 32 arranged relatively, and the first baking part 31 is provided with a second loading port 311, and the second loading port 311 can be used for placing the capacitor in the baking mechanism 3, and can also be used for the second loading port 311 to take the capacitor out of the baking mechanism 3. A plurality of baking racks 33 are provided in the baking mechanism 3, and the baking racks 33 are used to load the capacitors. The circulation component 34 drives the baking racks 33 to circulate and rotate in the baking mechanism 3, which is convenient for the capacitors on the plurality of baking racks 33 to be heated evenly and improve the baking efficiency; on the other hand, the plurality of baking racks 33 are moved to the second loading port 311 in sequence, so that the first loading mechanism 4 can take out the baked capacitors.

[0074] See also Fig.10The circulation component 34 includes an upper translation member 341, a lower translation member 342, a first lifting member 343 and a second lifting member 344. The upper translation member 341 is slidably arranged at the top of the baking mechanism 3 along the horizontal direction. The first baking part 31 is provided with a loading station 312 and a replenishing station 313. The upper translation member 341 is used to transport the baking rack 33 from the loading station 312 to the second baking part 32; the lower translation member 342 is slidably arranged at the bottom of the baking mechanism 3 along the horizontal direction, and the lower translation member 342 is used to transport the baking rack 33 from the second baking part 32 to the replenishing station 313; the first lifting member 343 is arranged at the bottom of the first baking part 31, and the first lifting member 343 is movably arranged in the vertical direction. The first lifting member 343 is used to push the baking rack 33 from the replenishing station 313 to the loading station 312.

[0075] In actual application, a loading station 312 is provided on the top of the first baking section 31, and the second loading port 311 is connected to the loading station 312. Along the vertical direction, that is, the height direction of the first baking section 31, a plurality of baking racks 33 are provided in the first baking section 31. The first lifting member 343 is used to push the plurality of baking racks 33 to the loading station 312 in sequence, and then the first loading mechanism 4 takes out the capacitor on the baking rack 33 at the loading station 312 to transport it to the impregnation cylinder 51 for impregnation.

[0076] At the same time, a replenishing station 313 is provided at the bottom of the first baking section 31. After the baking rack 33 at the loading station 312 has taken all the materials, the upper translation member 341 moves the baking rack 33 to the second baking section 32. At this time, the lower translation member 342 moves the baking rack 33 of the second baking section 32 to the replenishing station 313, so as to replenish the baking rack 33 to the first baking section 31 in time, and ensure that there are enough baking racks 33 in the first baking section 31 for the first loading mechanism 4 to take all the materials.

[0077] When the upper translation member 341 drives the baking rack 33 to move to the second baking portion 32 , in order to separate the baking rack 33 from the upper translation member 341 , a second lifting member 344 is disposed at the bottom of the second baking portion 32 .

[0078] The second lifting member 344 is arranged to move in the vertical direction. When the upper translation member 341 and the lower translation member 342 move to the second baking portion 32, the second lifting member 344 rises to push the baking rack 33 to separate from the upper translation member 341, and the second lifting member 344 descends to drive the baking rack 33 to move to the lower translation member 342.

[0079] In practical applications, both the upper translation member 341 and the lower translation member 342 can be provided with a limiting groove 3411, and the baking rack 33 is located in the limiting groove 3411, so that the upper translation member 341 and the lower translation member 342 can drive the baking rack 33 to move, and the baking rack 33 can be placed and separated by the first lifting member 343 and the second lifting member 344. Specifically, when the upper translation member 341 drives the baking rack 33 to move to the second baking portion 32, the second lifting member 344 moves upward, and the second lifting member 344 drives the second baking portion 32 to move. 2 rises, thereby driving the baking racks 33 to disengage from the limiting grooves 3411 of the upper translation member 341, and then the upper translation member 341 moves back to the first baking section 31; at this time, the first lifting member 343 can drive all the baking racks 33 of the first baking section 31 to rise, and replenish the baking racks 33 to the upper feeding station 312, and when the upper translation member 341 moves back to the first baking section 31, the first lifting member 343 descends, so that the baking racks 33 at the feeding station 312 fall into the limiting grooves 3411 of the upper translation member 341.

[0080] Similarly, when the lower translation member 342 moves to the second baking portion 32, the second lifting member 344 descends, so that the baking rack 33 falls into the limiting groove 3411 of the lower translation member 342, and the lower translation member 342 drives the baking rack 33 to move to the feeding station 313, and the first lifting member 343 rises to push the baking rack 33 out of the limiting groove 3411 of the lower translation member 342, so that the baking rack 33 is separated from the lower translation member 342. In this way, the baking rack 33 is circulated and rotated in the baking mechanism 3 through the upper translation member 341, the lower translation member 342, the first lifting member 343 and the second lifting member 344, and the structure is simple, the operation is convenient, and it is conducive to saving production costs.

[0081] It should be noted that, in some other embodiments, the upper translation member 341 and the lower translation member 342 may also be connected to and disconnected from the baking rack 33 in other ways, and the present application does not limit this.

[0082] See also Fig.11The baking mechanism 3 includes a first limit member 35, which is connected to the first baking portion 31 and is located above the feeding station 313. The first limit member 35 includes a first fixed portion 351, a first movable portion 352 and a second elastic member 353. The first fixed portion 351 is connected to the first baking portion 31, the first movable portion 352 is movably connected to the first fixed portion 351, and the second elastic member 353 abuts against the first movable portion 352 and the first fixed portion 351 respectively. The second elastic member 353 pushes the first movable portion 352 to extend out of the first fixed portion 351, and the baking rack 33 overlaps the first movable portion 352; when the first lifting member 343 pushes the baking rack 33 located at the feeding station 313 to move toward the upper feeding station 312, the baking rack 33 located at the feeding station 313 pushes the first movable portion 352 to retract to the first fixed portion 351.

[0083] In actual application, the first limit member 35 is mainly used to overlap the baking rack 33 in the first baking section 31 to limit the baking rack 33 in the first baking section 31 from falling. The baking rack 33 in the first baking section 31 is configured to move only in one direction, that is, the baking rack 33 in the first baking section 31 can only move upward. The first baking section 31 is mainly used for the first loading mechanism 4 to take materials. Therefore, the first baking section 31 needs to be replenished in time. Therefore, the baking rack 33 in the first baking section 31 is configured to move toward the loading station 312, which can improve the efficiency of replenishing materials.

[0084] Specifically, the first fixed portion 351 is connected to the first baking portion 31 and is located at the previous station of the feeding station 313. One end of the first movable portion 352 is rotatably connected to the first fixed portion 351 and abuts against the first fixed portion 351, and the other end elastically abuts against the first fixed portion 351 through the second elastic member 353. Therefore, the first movable portion 352 can only rotate in a single direction relative to the first fixed portion 351, that is, the first movable portion 352 rotates in a direction close to the second elastic member 353 to compress the second elastic member 353. When feeding, the second elastic member 353 will The first movable portion 352 extends out of the first fixed portion 351. The first movable portion 352 is used to overlap the baking rack 33 to prevent the baking rack 33 above the feeding station 313 from falling. When feeding is needed, the first lifting member 343 rises, pushing the baking rack 33 to rise. The baking rack 33 abuts the first movable portion 352 and pushes the first movable portion 352 to rotate in the direction close to the second elastic member 353. The second elastic member 353 is compressed, and then the first movable portion 352 retracts into the first fixed portion 351, so that the baking rack 33 can rise smoothly, and the feeding is timely achieved. When the feeding is completed, the baking rack 33 no longer abuts the first movable portion 352, and the second elastic member 353 elastically returns to its original state, so that the first movable portion 352 extends out of the first fixed portion 351 again to overlap the baking rack 33.

[0085] See also Fig.12 The baking mechanism 3 also includes a second limiting member 36, which includes a second fixed portion 361, a second movable portion 362, a third elastic member 363 and a supporting portion 364. The second fixed portion 361 is connected to the second baking portion 32, the second movable portion 362 is movably connected to the second fixed portion 361, the third elastic member 363 is respectively abutted against the second fixed portion 361 and the second movable portion 362, the supporting portion 364 is slidably connected to the second baking portion 32, and the supporting portion 364 is used to push the second movable portion 362 to extend out of the second fixed portion 361 to overlap the baking rack 33; the third elastic member 363 is used to drive the second movable portion 362 to retract to the second fixed portion 361.

[0086] In practical applications, the second limiting member 36 is mainly used to overlap the baking rack 33 in the second baking portion 32. Specifically, the second limiting member 36 is arranged at the previous station of the feeding station 313. The second limiting member 36 includes a second fixed portion 361, a second movable portion 362, a third elastic member 363 and a supporting portion 364. The supporting portion 364 is slidably connected to the second baking portion 32. During the sliding process, the supporting portion 364 pushes the second movable portion 362 to extend out of the second fixed portion 361. The second movable portion 362 is used to overlap the baking rack 33. When the second lifting member 344 descends, the supporting portion 36 The third elastic member 363 drives the second movable member 362 to retract into the second fixed member 361, so that the baking rack 33 can fall onto the lower translation member 342. When the baking rack 33 falls onto the lower translation member 342, the abutting member 364 slides to abut against the second movable member 362, and the abutting member 364 pushes the second movable member 362 to extend, so as to overlap the upper baking rack 33 and separate the upper baking rack 33, so as to prevent the upper baking rack 33 from falling onto the lower translation member 342 and affecting the lower translation member 342 to drive the baking rack 33 to move to the feeding station 313.

[0092] S3, after the impregnation cylinder 51 on the second station 12 is filled with materials, the impregnation cylinder 51 on the second station 12 moves to the first station 11 to impregnate the materials for a preset time; at the same time, another impregnation cylinder 51 moves to the second station 12, and the first feeding mechanism 4 transports the baked materials to the impregnation cylinder 51 on the second station 12;

After the impregnation cylinder 51 located on the first station 11 impregnates the material for a preset time, the impregnation cylinder 51 is drained, and the impregnation cylinder 51 after draining is moved to the second station 12 again. The first loading mechanism 4 takes the impregnated material out of the impregnation cylinder 51 located on the second station 12 and moves it to the next process.

[0095] Among them, the impregnation equipment also includes a liquid storage mechanism 6, which is connected to the impregnation cylinder 51 and is used to fill and drain the impregnation cylinder 51; the number of impregnation cylinders 51 can be set according to the actual impregnation time. For example, the impregnation cylinder 51 can be set to 4, and the loading time of each impregnation cylinder 51 is almost the same. The impregnation time of the capacitor can be the loading time of the 4 impregnation cylinders 51. When the 4 impregnation cylinders 51 are loaded in sequence, the first loaded impregnation cylinder 51 just reaches the preset impregnation time, and the impregnation cylinder 51 moves to the second station 12 again. The protection mechanism 7 is covered on the impregnation cylinder 51 to prevent it from being exposed. The first loading mechanism 4 takes the impregnated material out of the impregnation cylinder 51 located on the second station 12 and moves it to the next process.
