[0002] In traditional impregnation machines for solid-state capacitors, the number of impregnation tanks is the same as the number of sealing covers, that is, one impregnation tank corresponds to one sealing cover. Multiple iron bars are usually hung in sequence in the impregnation tank, and multiple core packs for making solid-state capacitors are fixed on each iron bar. After impregnation, the sealing cover is completely opened, and then a robotic arm is used to take out an iron bar from the open impregnation tank to the next station, while the other iron bars remain in the open impregnation tank. The open impregnation tank may cause the solvent in the electrolyte to volatilize, change the concentration of the electrolyte, and affect the impregnation effect of the core packs taken out later; moreover, for a completely open impregnation tank, dust, moisture or oxygen in the air may contaminate the electrolyte, resulting in a decline or failure in the performance of the finished capacitors, and it is difficult to ensure the consistency of the finished capacitors in each batch. Summary of the Invention

Specific implementation mode
[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0028] The present invention provides a core package impregnator for solid-state capacitors, which includes an impregnation tank and a sealing cover. The sealing cover includes a normal sealing cover and an auxiliary sealing cover. The normal sealing cover is arranged on the impregnation tank and covers the impregnation tank, and the auxiliary sealing cover is arranged on one side of the impregnation tank.
[0029] When it is necessary to take out the iron bar at the edge of the impregnation tank, just slightly move the normal sealing cover to expose a small gap, and then the iron bar can be taken out; when taking out the iron bar in the middle, at this time, the normal sealing cover and the auxiliary sealing cover can be moved closer to each other and abutted, and then the normal sealing cover and the auxiliary sealing cover are moved simultaneously, so that during the process of moving the normal sealing cover and the auxiliary sealing cover, the normal sealing cover and the auxiliary sealing cover can always completely cover the impregnation tank. When moving to the predetermined position, the normal sealing cover and the auxiliary sealing cover are moved away from each other to expose a small gap and the iron bar is taken out, and then the normal sealing cover and the auxiliary sealing cover are moved closer to each other and abutted until they are closed and completely cover the impregnation tank, and then the normal sealing cover and the auxiliary sealing cover are moved simultaneously and reset. It can ensure that when taking out the iron bar in the middle, the area of the impregnation tank exposed to the external environment is still minimized, the influence of the external environment on the internal environment of the impregnation tank is reduced to the greatest extent, the electrolyte is prevented from being polluted by dust, moisture or oxygen in the air, the performance of the finished capacitor is improved, and the impregnation quality of the core package for solid-state capacitors and the consistency of the core packages between batches are guaranteed.
[0030] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings. The present invention will be described in detail below with reference to the drawings and embodiments. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.
[0031] Example 1, please refer to Figures 1 to 6, a core impregnation machine provided for the present invention. The solid-state capacitor is a semi-solid-state capacitor or a fully solid-state capacitor. The core impregnation machine for the solid-state capacitor includes an impregnation tank 1 and a sealing cover. The sealing cover includes a normal sealing cover 2 and an auxiliary sealing cover 3. The outer shapes and functions of the normal sealing cover 2 and the auxiliary sealing cover 3 are exactly the same, that is, the normal sealing cover 2 and the auxiliary sealing cover 3 can be two completely identical sealing covers. In other embodiments, the normal sealing cover 2 and the auxiliary sealing cover 3 can also be sealing covers with certain differences. The normal sealing cover 2 and the auxiliary sealing cover 3 are alternatively covered on the impregnation tank 1 or cooperatively covered on the impregnation tank 1 so that a gap is exposed in the impregnation tank 1 to facilitate the manipulator to grab one or a small number of core package components in the impregnation tank 1. In this embodiment, the normal sealing cover 2 is arranged on the impregnation tank 1 and covers the impregnation tank 1, and the auxiliary sealing cover 3 is arranged on one side of the impregnation tank 1. When it is necessary to take out the iron bar 4 at the edge of the impregnation tank 1, only the normal sealing cover 2 needs to be slightly moved away to expose a small slit to take out the iron bar 4; when it is necessary to take out the iron bar 4 in the middle, at this time, the normal sealing cover 2 and the auxiliary sealing cover 3 can be abutted against each other, and then the normal sealing cover 2 and the auxiliary sealing cover 3 are moved simultaneously so that during the process of moving the normal sealing cover 2 and the auxiliary sealing cover 3, the normal sealing cover 2 and the auxiliary sealing cover 3 can always completely cover the impregnation tank 1. When moving to a predetermined position, the normal sealing cover 2 and the auxiliary sealing cover 3 are moved away from each other to expose a small slit and take out the iron bar 4, and then the normal sealing cover 2 and the auxiliary sealing cover 3 are abutted against each other until they are closed and completely cover the impregnation tank 1, and then the normal sealing cover 2 and the auxiliary sealing cover 3 are moved simultaneously and reset. It can ensure that when taking out the iron bar 4 in the middle, the area of the impregnation tank 1 exposed to the external environment is minimized, and the influence of the external environment on the internal environment of the impregnation tank 1 is minimized, avoiding the pollution of the electrolyte by dust, moisture or oxygen in the air, improving the performance of the finished capacitor, and ensuring the impregnation quality of the core package for the solid-state capacitor and the consistency of the core packages between batches.
[0032] When it is necessary to take out multiple iron bars 4 at the same time, the size of the slit exposed by the normal sealing cover 2 and the auxiliary sealing cover 3 can also be adjusted at any time, which can make the exposed slit always remain the smallest to ensure that the area of the impregnation tank 1 exposed to the external environment is minimized and the influence of the external environment on the internal environment of the impregnation tank 1 is minimized. Although this operation method makes the slit exposed by the normal sealing cover 2 and the auxiliary sealing cover 3 larger, it can take out multiple iron bars 4 at the same time in a short time, making the time for exposing the slit shorter.
[0033] Of course, when multiple iron bars 4 need to be taken out, one can also be taken out at a time, and then the normal sealing cover 2 and the auxiliary sealing cover 3 can be repeatedly moved to take out multiple iron bars 4, so that the exposed gap can always be kept to a minimum. However, this also makes the exposure time of the impregnation tank 1 relatively long. Therefore, the method of taking out multiple iron bars 4 simultaneously as described above can also be adopted.
[0034] When the number of impregnation tanks 1 is small and the positions of the normal sealing cover 2 and the auxiliary sealing cover 3 can be finely controlled, before taking out the iron bars 4, the normal sealing cover 2 and the auxiliary sealing cover 3 can always be in contact with each other, and they are only separated when the middle of the normal sealing cover 2 and the auxiliary sealing cover 3 is above the iron bar 4 to be taken out.
[0035] Example 2, please refer to Figures 1 to 6 , as a further optimized solution of Example 1, the number of impregnation tanks 1 is the same as the number of normal sealing covers 2, and there is at least one auxiliary sealing cover 3. In this embodiment, there are two impregnation tanks 1, two normal sealing covers 2, and one auxiliary sealing cover 3, and the auxiliary sealing cover 3 is arranged between the two normal sealing covers 2. When the left impregnation tank 1 needs to be opened, the auxiliary sealing cover 3 moves to the edge of the left normal sealing cover 2 to the left, and then cooperates with it to open the gap to take out the iron bar 4; when the right impregnation tank 1 needs to be opened, the auxiliary sealing cover 3 moves to the edge of the right normal sealing cover 2 to the right, and then cooperates with it to open the gap to take out the iron bar 4.
[0036] Of course, in other embodiments, it can also be that three impregnation tanks 1 are paired with one auxiliary sealing cover 3 for use, or one impregnation tank 1 is paired with one auxiliary sealing cover 3 for use, so that multiple impregnation tanks 1 can be operated simultaneously without waiting for the operation of the previous impregnation tank 1 to be completed before proceeding. It can be adjusted according to its actual production needs, and all of them should fall within the protection scope of the present invention.
[0037] Further, the normal sealing cover 2 and the auxiliary sealing cover 3 move horizontally and vertically relative to the impregnation tank 1. A slide rail 51 is provided on one side of the impregnation tank 1. A slider 52 is arranged on the slide rail 51. One slider 52 is correspondingly arranged for the normal sealing cover 2 and the auxiliary sealing cover 3 respectively. The normal sealing cover 2 and the auxiliary sealing cover 3 are arranged on the slide rail 51 through the slider 52. Each normal sealing cover 2 and each auxiliary sealing cover 3 are connected with a linear motor 53 through the slider 52. Each normal sealing cover 2 and each auxiliary sealing cover 3 are driven by the linear motor 53 to move horizontally along the slide rail 51. The linear motor 53 is used for horizontal movement. During operation, the linear motor 53 drives the slider 52 to slide on the slide rail 51. The slider 52 drives the normal sealing cover 2 and the auxiliary sealing cover 3 to linearly move back and forth on the slide rail 51. And the normal sealing cover 2 and the auxiliary sealing cover 3 can move back and forth independently. It can enable the normal sealing cover 2 and the auxiliary sealing cover 3 to stay at any position on the slide rail 51 to take out the iron bars 4 at any position in the impregnation tank 1. If a single motor is used to control the normal sealing cover 2 and the auxiliary sealing cover 3 to move towards each other or away from each other simultaneously, then the gap exposed when the normal sealing cover 2 and the auxiliary sealing cover 3 are at the middle position is the smallest. If the iron bar 4 to be taken out is not at the middle position, then the normal sealing cover 2 and the auxiliary sealing cover 3 need to open a larger gap to take out the iron bar 4. This is not conducive to ensuring that the area of the impregnation tank 1 exposed to the external environment is the smallest and cannot minimize the influence of the external environment on the internal environment of the impregnation tank 1 to the greatest extent.
[0038] Further, each normal sealing cover 2 and each auxiliary sealing cover 3 are vertically lifted and lowered through a lifting motor 54. The lifting motor 54 is used for vertical lifting and lowering, so that each normal sealing cover 2 and each auxiliary sealing cover 3 can move up and down freely. When it is necessary to move the normal sealing cover 2 and the auxiliary sealing cover 3, the normal sealing cover 2 and the auxiliary sealing cover 3 can be lifted up by a certain distance through the lifting motor 54 first to avoid collision interference between the normal sealing cover 2 and the auxiliary sealing cover 3 and the impregnation tank 1. After the horizontal movement of the normal sealing cover 2 and the auxiliary sealing cover 3 is completed, the normal sealing cover 2 and the auxiliary sealing cover 3 can be lowered by a certain distance for reset through the lifting motor 54, so that the normal sealing cover 2 and the auxiliary sealing cover 3 can press on the impregnation tank 1 and seal it.
[0039] In this embodiment, there are two normal sealing covers 2 and one auxiliary sealing cover 3. Correspondingly, two slide rails 51 are provided on the upper surface of the support frame 55. The two slide rails 51 are arranged left and right and are connected end to end to form a straight line. Two sliders 52 are correspondingly arranged for the two normal sealing covers 2, and the two sliders 52 are respectively arranged on the two slide rails 51. And a section of slide rail 51 is provided on the lower surface of the support frame 55, and this section of slide rail 51 corresponds to the slider 52 of the auxiliary sealing cover 3. The two sealing covers move left and right respectively on their respective slide rails 51 through the sliders 52. And the slide rail 51 on the lower surface of the support frame 55 enables the moving path of the auxiliary sealing cover 3 to overlap with the moving paths of the two normal sealing covers 2. Furthermore, the two normal sealing covers 2 can move independently, and the auxiliary sealing cover 3 can be abutted against any one of the normal sealing covers 2.
[0040] Please refer to Figure 7 and Figure 8 , further, a fixing plate 56 is provided on each slider 52 of the normal sealing cover 2 or the auxiliary sealing cover 3. The lifting motor 54 is arranged on the fixing plate 56. The fixing plate 56 is connected to the normal sealing cover 2 or the auxiliary sealing cover 3 through a hinge structure 57. The hinge structure 57 includes a first hinge and a second hinge that are hinged to each other. The first hinge is fixed to the fixing plate 56, and the second hinge is fixed to the normal sealing cover 2 or the auxiliary sealing cover 3. That is, one end of the hinge structure 57 is fixed to the fixing plate 56, and the other end of the hinge structure 57 is fixed to the normal sealing cover 2 or the auxiliary sealing cover 3. The lifting motor 54 is connected to the other end of the hinge structure 57. When the lifting motor 54 works, it drives the normal sealing cover 2 or the auxiliary sealing cover 3 to rise or fall within the range defined by the hinge structure 57, and the hinge structure 57 plays a role of support, limit and buffering.
[0041] That is, in this embodiment, there are two normal sealing covers 2, which include a left normal sealing cover 21 and a right normal sealing cover 21, and there is one auxiliary sealing cover 3. There are three slide rails 51, which include an upper left slide rail 511, an upper right slide rail 512, and a lower slide rail 513. There are three sliders 52, which include an upper left slider 521, an upper right slider 522, and a lower slider 523. There are three linear motors 53, which include an upper left linear motor 531, an upper right linear motor 532, and a lower linear motor 533. There are three sets of lifting motors 54, which include a left lifting motor set 541, a right lifting motor set 542, and a middle lifting motor set 543. Each lifting motor set is equipped with two lifting motors 54, and the two lifting motors 54 are respectively arranged on both sides of the normal sealing cover 2 or the auxiliary sealing cover 3. Each linear motor 53 is connected to a lead screw 58, and there are a total of three lead screws 58, which include an upper left lead screw 581, an upper right lead screw 582, and a lower lead screw 583. There are three fixing plates 56, which include a left fixing plate 561, a right fixing plate 562, and a middle fixing plate 563. There are three hinge structures 57, which include a left hinge structure 571, a right hinge structure 572, and a middle hinge structure 573.
[0042] In this embodiment, the upper left slide rail 511 and the upper right slide rail 512 are laid on the upper surface of the support frame 55, and the lower slide rail 513 is laid on the lower surface of the support frame 55. An upper left lead screw 581 is arranged above the upper left slide rail 511, and one end of the upper left lead screw 581 is connected to the upper left linear motor 531; an upper right lead screw 582 is arranged above the upper right slide rail 512, and one end of the upper right lead screw 582 is connected to the upper right linear motor 532; a lower lead screw 583 is arranged below the lower slide rail 513, and one end of the lower lead screw 583 is connected to the lower linear motor 533.
[0043] An upper left slider 521 is arranged on the upper left slide rail 511, a left fixing plate 561 is fixed on the upper left slider 521, a left lifting motor set 541 is arranged on both sides of the left fixing plate 561, a left hinge structure 571 is further connected to the left fixing plate 561, and a left normal sealing cover 21 is connected below the left hinge structure 571; an upper right slider 522 is arranged on the upper right slide rail 512, a right fixing plate 562 is fixed on the upper right slider 522, a right lifting motor set 542 is arranged on both sides of the right fixing plate 562, a right hinge structure 572 is further connected to the right fixing plate 562, and a right normal sealing cover 21 is connected below the right hinge structure 572; a lower slider 523 is arranged on the lower slide rail 513, a middle fixing plate 563 is fixed on the lower slider 523, a middle lifting motor set 543 is arranged on both sides of the middle fixing plate 563, a middle hinge structure 573 is further connected to the middle fixing plate 563, and a middle normal sealing cover 2 is connected below the middle hinge structure 573.
[0044] Further, a limiting groove 31 is provided on the side of the auxiliary sealing cover 3 close to the normal sealing cover 2. In this embodiment, two normal sealing covers 2 are arranged on both sides of the auxiliary sealing cover 3. Therefore, limiting grooves 31 are provided on both sides of the auxiliary sealing cover 3. The limiting groove 31 is used to place a sealing strip, so that when the normal sealing cover 2 and the auxiliary sealing cover 3 move synchronously and abut, the sealing performance at the connection between the normal sealing cover 2 and the auxiliary sealing cover 3 can be ensured, preventing gas from leaking out through the gap between the normal sealing cover 2 and the auxiliary sealing cover 3, thereby ensuring that the area of the impregnation tank 1 exposed to the external environment is minimized and the impact of the external environment on the internal environment of the impregnation tank 1 is reduced to the greatest extent.
[0045] Please refer to Figure 9 , further, a sealing groove 11 is provided on the upper surface of the impregnation tank 1, and a sealing ring 6 is arranged on the sealing groove 11, so that when the impregnation tank 1 is covered by the normal sealing cover 2, the sealing ring 6 can be pressed, thereby improving the sealing performance and preventing air leakage.
[0046] Please refer to Figure 10 , further, the shape of the impregnation tank 1 is a rectangular barrel shape, and the shapes of the normal sealing cover 2 and the auxiliary sealing cover 3 are both cuboids. The rectangular barrel-shaped impregnation tank 1 is more suitable for actual production, and the rectangular normal sealing cover 2 and auxiliary sealing cover 3 can well ensure that the rectangular barrel-shaped impregnation tank 1 is always covered during movement. If the impregnation tank 1 is circular, then the outer shapes of the normal sealing cover 2 and the auxiliary sealing cover 3 are usually also designed to be circular. At this time, during the process of moving the normal sealing cover 2 and the auxiliary sealing cover 3, it is very difficult for the normal sealing cover 2 and the auxiliary sealing cover 3 to completely cover the impregnation tank 1, making the impregnation tank 1 easily exposed to the external environment.
[0047] Further, material racks 7 are provided on both sides of the impregnation tank 1. A plurality of V-shaped grooves 71 are provided on the material racks 7, and the core package assemblies are placed in the V-shaped grooves 71; each core package assembly includes an iron bar 4 and a plurality of core packages 8 welded to the iron bar 4. An iron bar 4 is provided on each V-shaped groove 71, and a plurality of core packages 8 for manufacturing solid-state capacitors are welded and fixed on each iron bar 4. One of the pins of the core package 8 is welded and fixed to the iron bar 4, and when an iron bar 4 is taken out each time, a plurality of core packages 8 on the entire iron bar 4 can be taken out. A drain port 12 is provided at the lowest point of the bottom of the impregnation tank 1, and the waste electrolyte can be discharged through the drain port 12.
[0048] The present invention provides a method for impregnating a core package for a solid-state capacitor. The solid-state capacitor is a semi-solid-state capacitor or a fully solid-state capacitor, and it includes the following steps: Step 1, provide an impregnation tank and a sealing cover. The sealing cover includes a normal sealing cover and an auxiliary sealing cover. The normal sealing cover covers the impregnation tank, and the auxiliary sealing cover is arranged on one side of the normal sealing cover; Step 2: Horizontally move the normal sealing cover and the auxiliary sealing cover to a predetermined position. During the movement, keep the normal sealing cover and the auxiliary sealing cover in contact with each other and completely cover the impregnation tank. Step 3: Open the normal sealing cover and the auxiliary sealing cover to keep a certain gap therebetween. Step 4: Take out the articles in the impregnation tank from the gap. Step 5: Close the normal sealing cover and the auxiliary sealing cover so that they are in contact with each other and completely cover the impregnation tank. Step 6: Move the normal sealing cover and the auxiliary sealing cover and reset them.
[0049] When it is necessary to take out the iron bar at the edge of the impregnation tank, just slightly move the normal sealing cover to expose a small slit for taking out the iron bar. When taking out the iron bar in the middle, at this time, the normal sealing cover and the auxiliary sealing cover can be moved closer to each other and abutted. Then, move the normal sealing cover and the auxiliary sealing cover simultaneously so that during the movement of the normal sealing cover and the auxiliary sealing cover, the normal sealing cover and the auxiliary sealing cover can always completely cover the impregnation tank. When moving to the predetermined position, move the normal sealing cover and the auxiliary sealing cover away from each other to expose a small slit and take out the iron bar. Then, move the normal sealing cover and the auxiliary sealing cover closer to each other and abut until they are closed and completely cover the impregnation tank, and then move the normal sealing cover and the auxiliary sealing cover simultaneously and reset them. This can ensure that when taking out the iron bar in the middle, the area of the impregnation tank exposed to the external environment is minimized, and the influence of the external environment on the internal environment of the impregnation tank is reduced to the greatest extent.
[0050] Further, in Step 2: Move the normal sealing cover and the auxiliary sealing cover upward by a certain distance, and horizontally move the normal sealing cover and the auxiliary sealing cover to a predetermined position. During the movement, keep the normal sealing cover and the auxiliary sealing cover in contact with each other and completely cover the impregnation tank.
