Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of solid-liquid hybrid capacitors, and in particular relates to a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting an electrolyte. Background Art

[0002] Solid-liquid hybrid capacitors are solid-liquid hybrid aluminum electrolytic capacitors, or hybrid capacitors for short. They are a new type of capacitor that uses two electrolytes, solid and liquid. They are electronic components that combine the characteristics of solid capacitors and liquid capacitors, and have the advantages of high capacity, low leakage current, and self-healing capabilities. The structure of this capacitor is basically similar to that of a solid capacitor, but in addition to the conductive polymer of the solid capacitor, an electrolyte is also added to the electrolyte.

[0003] During the manufacturing process of solid-liquid hybrid capacitors, a certain amount of electrolyte must be injected into the aluminum shell of the capacitor. The current method of injecting electrolyte is manual injection, and the amount of electrolyte injected is manually controlled, which will cause the amount of electrolyte injected into the aluminum shell of the capacitor to be inaccurate. In response to the above-mentioned technical problems, the applicant has retrieved some prior arts to achieve quantitative injection of electrolyte, such as the patent publication number CN114628868B, whose main technical means is to use a quantitative bin to quantitatively extract and quantitatively add electrolyte, thereby improving the accuracy of electrolyte addition. According to the applicant's analysis, the disadvantage of this technical solution is that in the process of adding electrolyte, a part of the electrolyte in the quantitative bin will adhere to the inner wall of the quantitative bin, resulting in a small amount of electrolyte added each time, and the amount added each time is not uniform, resulting in a large error in the amount of addition. Summary of the invention

[0004] The purpose of the present invention is to address the shortcomings of the prior art and provide a method for manufacturing a solid-liquid hybrid capacitor with quantitative injection of electrolyte, so as to solve the technical problem that during the process of dripping electrolyte, a part of the electrolyte in the quantitative bin will adhere to the inner wall of the quantitative bin, resulting in a small amount of electrolyte dripped each time and the amount of electrolyte dripped each time is not uniform.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0021] As a preferred embodiment of the above technical solution, the shaking driving member includes a movable rod, which is hingedly installed on the surface of the driving rod, and an elastic member is connected between the upper and lower surfaces of the movable rod and the driving rod, and slopes are symmetrically provided at the middle position of the cover plate. When the driving rod moves downward, the movable rod contacts the slope on the cover plate, causing the connecting member to move downward.

[0023] A driving ring, the driving ring is fixedly connected to the driving rod through a connecting rod, and the driving ring is sleeved on the periphery of the injection tube;

[0024] Guide grooves, two guide grooves are cross-opened on the inner side of the driving ring, and a guide rail is arranged on the periphery of the injection tube. The guide rail is in a spiral curved shape, and the guide rail is stuck in the guide groove.

[0025] As a preferred embodiment of the above technical solution, the guide rail is divided into two sections, the two sections of the guide rail are symmetrical along the horizontal line of the center position of the injection tube, and through holes are opened on the annular block and the cover plate, and the connecting rod passes through the through holes.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. In the present invention, the driving rod is moved downward by extending the telescopic member, so that the piston moves downward in the injection tube, so that the electrolyte in the injection tube is injected into the capacitor aluminum shell. When the driving rod moves downward, the shaking driving member on the driving rod contacts the cover plate on the connecting member, and the movable rod on the shaking driving member rotates upward. Due to the pressure of the movable rod, the connecting member moves downward, so that the elastic member 2 is compressed, and the movable rod rotates slowly. Through the cooperation of the wedge shape and the slope of the movable end of the movable rod, the movable rod passes over the top of the cover plate to the bottom of the cover plate. When the movable rod reaches the bottom of the cover plate, the cover plate is released from the restriction, and the support ring drives the connecting member and the injection tube to move upward through the rebound ability of the elastic member 2. In this way, the injection tube is shaken up and down, so that the electrolyte attached to the inner wall of the injection tube is shaken off and enters the capacitor aluminum shell, so that the quantitative electrolyte enters the capacitor aluminum shell as completely as possible, effectively avoiding the amount of electrolyte injected each time being too small and not uniform;

[0032] 2. In the present invention, the driving rod is moved downward by extending the telescopic member, and the driving rod drives the driving ring to move downward through the connecting rod. As the piston slides relative to the inner wall of the injection tube, the guide rail will move along the guide groove, causing the injection tube to rotate. Moreover, as the two sections of the guide rail are symmetrical and cooperate with the two intersecting guide grooves, when the driving ring is at the first section of the guide rail, the injection tube rotates, and when the driving ring is at the second section of the guide rail, the injection tube reverses. During the downward movement of the driving rod, the injection tube is reversed. During the rotation of the injection tube, the electrolyte attached to the inner wall of the injection tube will be in a flowing state. Cooperating with the up and down shaking of the injection tube, the electrolyte attached to the inner wall of the injection tube is more easily thrown off, thereby enhancing the effect of cleaning the electrolyte from the inner wall of the injection tube, thereby further avoiding that the amount of electrolyte injected each time is too small and not uniform.

[0033] 3. In the present invention, the driving rod is moved downward by extending the telescopic part. During the downward movement, the scraper scrapes off the electrolyte attached to the inner wall of the injection tube. The up and down shaking and rotation of the injection tube further enhances the effect of cleaning the electrolyte from the inner wall of the injection tube, thereby further avoiding the small and uneven amount of electrolyte injected each time.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example

[0047] like Figure 1-Figure 6 As shown, a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting electrolyte includes the following steps:

[0048] Step S1: placing the capacitor aluminum shell to be injected with electrolyte on the lifting platform 6;

[0049] Step S2: injecting a certain amount of electrolyte into the injection tube 4 through the liquid inlet tube 43, and closing the electric control valve 431 on the liquid inlet tube 43;

[0050] Step S3: The capacitor aluminum shell is moved upward by raising the lifting platform 6, so that the sealing cover 44 covers the capacitor aluminum shell, thereby sealing the capacitor aluminum shell;

[0051] Step S4: The driving rod 21 and the piston 22 are driven to move downward in the injection tube 4 by the telescopic member 2, so that the electrolyte in the injection tube 4 is injected into the aluminum shell of the capacitor;

[0052] Step S5: When the driving rod 21 moves downward, the injection tube 4 is shaken up and down by the cooperation between the shaking driving member 211 and the connecting member 41, so that the electrolyte attached to the inner wall of the injection tube 4 is shaken down and enters the aluminum shell of the capacitor;

[0053] Step S6: After the electrolyte is injected, the capacitor aluminum shell is moved downward by the lifting platform 6, and the driving rod 21 and the piston 22 are driven to move upward by the telescopic member 2.

[0054] In one case of this embodiment, the lifting platform 6 may be a component capable of actively changing its length, so as to control the height of the capacitor aluminum shell.

[0055] like Figure 1-Figure 6 As shown, a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting an electrolyte provided by the present invention is applied to a solid-liquid hybrid capacitor manufacturing device by quantitatively injecting an electrolyte, and the device includes:

[0056] Mounting frame 1;

[0057] The telescopic member 2 is mounted on the mounting frame 1, and the output end of the telescopic member 2 is rotatably connected to a driving rod 21, and a piston 22 is mounted on the other end of the driving rod 21;

[0058] A shaking frame 5, the shaking frame 5 is fixedly connected to the mounting frame 1;

[0059] The injection tube 4 is installed in the shaking frame 5, and the piston 22 is inserted in the injection tube 4 and slides relative to the inner wall of the injection tube 4.

[0060] In one case of this embodiment, the telescopic part 2 can be a cylinder, and of course it can also be a component that can drive the driving rod 21 to move up and down; when the piston 22 slides relative to the inner wall of the injection tube 4, the sealing is also taken into account, so that when the piston 22 moves downward, the electrolyte in the injection tube 4 will be discharged from the injection tube 4. At the same time, when the electrolyte is added to the injection tube 4, the electrolyte will not leak from the bottom of the injection tube 4.

[0061] In actual application of this embodiment, the telescopic member 2 is extended to move the driving rod 21 downward, so that the piston 22 moves downward in the injection tube 4, so that the electrolyte in the injection tube 4 is injected into the aluminum shell of the capacitor. When the driving rod 21 moves downward, the shaking frame 5 is used to shake the injection tube 4 up and down, so that the electrolyte attached to the inner wall of the injection tube 4 is shaken off and enters the aluminum shell of the capacitor, so that a certain amount of electrolyte can enter the aluminum shell of the capacitor as completely as possible, so that the amount of electrolyte injected each time is the same, and the purpose of quantitative injection of electrolyte is achieved.

[0062] Furthermore, the shaking frame 5 includes a collar 51, which is fixedly connected to the mounting frame 1 through a plurality of fixing rods 54, a support ring 53 is movably installed in the collar 51, and a plurality of elastic members 52 are connected between the support ring 53 and the collar 51;

[0063] The injection tube 4 is connected with a connector 41, which includes a circular ring block 411, which is fixedly connected to the top of the injection tube 4, and a cover plate 412 is fixed on the top of the circular ring block 411, and the cover plate 412 covers the support ring 53;

[0064] The piston 22 passes through the connecting piece 41 and extends into the injection tube 4. A plurality of shaking driving pieces 211 are provided on the driving rod 21.

[0065] In one case of this embodiment, the second elastic member 52 may be a spring, and of course may also be other elastic components.

[0066] In actual application of this embodiment, the driving rod 21 is moved downward to make the shaking driving member 211 contact with the cover plate 412, so that the connecting member 41 is moved downward, and the support ring 53 presses down the elastic member 52 to compress. When the shaking driving member 211 passes through the cover plate 412, the cover plate 412 is released from the restriction, and the support ring 53 drives the connecting member 41 and the injection tube 4 to move upward through the rebound ability of the elastic member 52. In this way, the injection tube 4 is shaken up and down, so that the electrolyte attached to the inner wall of the injection tube 4 is shaken off and enters into the aluminum shell of the capacitor, so that a certain amount of electrolyte enters into the aluminum shell of the capacitor as completely as possible.

[0067] Furthermore, the shaking driving member 211 includes a movable rod 2111, which is hingedly installed on the surface of the driving rod 21. An elastic member 2112 is connected between the upper and lower surfaces of the movable rod 2111 and the driving rod 21. A slope 4121 is symmetrically arranged at the upper and lower positions of the middle position of the cover plate 412. When the driving rod 21 moves downward, the movable rod 2111 contacts the slope 4121 on the cover plate 412, causing the connecting member 41 to move downward.

[0068] In one case of this embodiment, the elastic member 2112 can be a spring, and of course it can also be other elastic components; wherein the movable ends of the movable rod 2111 are wedge-shaped above and below, cooperating with the slope 4121 on the cover plate 412, so that the movable rod 2111 can bend and move under the cover plate 412 during the downward movement.

[0069] In actual application of this embodiment, during the downward movement of the driving rod 21, the movable rod 2111 contacts the cover plate 412, causing one of the two elastic members 2112 to extend and the other to be compressed. At the same time, due to the pressure of the movable rod 2111, the connecting member 41 moves downward, causing the elastic member 2 52 to be compressed, and the movable rod 2111 slowly rotates. Through the cooperation of the wedge shape of the movable end of the movable rod 2111 and the slope 4121, the movable rod 2111 passes over the top of the cover plate 412 to the bottom of the cover plate 412, so that the driving rod 21 can continue to move downward. When the movable rod 2111 reaches the bottom of the cover plate 412, the cover plate 412 is released from the restriction, so that the connecting member 41 drives the injection tube 4 to move upward and shake, thereby shaking the electrolyte attached to the inner wall of the injection tube 4 off and entering the capacitor aluminum shell, so that a certain amount of electrolyte enters the capacitor aluminum shell as completely as possible.

[0070] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting electrolyte provided by the present invention, a rotating mechanism 7 is installed outside the injection tube 4, and the rotating mechanism 7 includes:

[0071] A driving ring 71, the driving ring 71 is fixedly connected to the driving rod 21 through a connecting rod 72, and the driving ring 71 is sleeved on the periphery of the injection tube 4;

[0072] Guide groove 711 , two guide grooves 711 are cross-opened on the inner side of the driving ring 71 , and a guide rail 42 is arranged on the periphery of the injection tube 4 . The guide rail 42 is in a spiral curved shape and is stuck in the guide groove 711 .

[0073] In one case of this embodiment, the guide rail 42 slides relative to the guide groove 711, and the driving ring 71 is not sufficient to drive the injection tube 4 to move downward when moving downward.

[0074] In actual application of this embodiment, during the downward movement of the driving rod 21, the driving rod 21 drives the driving ring 71 to move downward through the connecting rod 72. Since the piston 22 slides relative to the inner wall of the injection tube 4, the guide rail 42 will be displaced along the guide groove 711, causing the injection tube 4 to rotate. During the rotation of the injection tube 4, the electrolyte attached to the inner wall of the injection tube 4 will be in a flowing state. With the up and down shaking of the injection tube 4, the electrolyte attached to the inner wall of the injection tube 4 can be thrown off and enter the aluminum shell of the capacitor, thereby enhancing the effect of cleaning the electrolyte from the inner wall of the injection tube 4.

[0075] Furthermore, the guide rail 42 is divided into two sections, the upper and lower sections, which are symmetrical along the horizontal line of the center position of the injection tube 4. The annular block 411 and the cover plate 412 are both provided with through holes 413, and the connecting rod 72 passes through the through holes 413.

[0076] In one case of the present embodiment, two sections of guide rails 42 correspond to two intersecting guide grooves 711, and the projection angle of each section of guide rail 42 in the longitudinal direction is less than 180°; wherein, the angle formed by the trajectory of the through hole 413 is less than 180°, and there are two connecting rods 72, which pass through the through holes 413 at two positions respectively; when a section of guide rail 42 is completed, the connecting rod 72 moves from one end of the through hole 413 to the other end of the through hole 413; when the drive ring 71 moves to the two guide rails 42 respectively, the rotation direction of the injection tube 4 is opposite.

[0077] In actual application of this embodiment, the driving rod 21 moves downward, driving the driving ring 71 to move downward, and the injection tube 4 is rotated through the cooperation of the guide rail 42 and the guide groove 711. When the driving ring 71 moves down to the lower section of the guide rail 42, the guide rail 42 at this time enters into another guide groove 711, causing the injection tube 4 to rotate in the opposite direction. During the downward movement of the driving rod 21, the injection tube 4 is reversed, and the injection tube 4 is shaken up and down, so that the electrolyte is easier to be thrown off.

[0078] like Figure 3 and Figure 5 As shown, a method for manufacturing a solid-liquid hybrid capacitor with quantitative electrolyte injection provided by the present invention is provided. A scraper 221 is provided at the bottom of the piston 22. The scraper 221 slides relative to the inner wall of the injection tube 4. An inwardly inclined oblique opening 2211 is provided at the bottom of the scraper 221.

[0079] In actual application of this embodiment, when the driving rod 21 moves downward, the scraper 221 scrapes off the electrolyte attached to the inner wall of the injection tube 4, and cooperates with the up and down shaking and rotation of the injection tube 4, further enhancing the effect of cleaning the electrolyte from the inner wall of the injection tube 4.

[0080] like Fig. 9 As shown, a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting electrolyte provided by the present invention, wherein a sealing cover 44 is installed on the periphery of the injection tube 4.

[0081] In one case of this embodiment, when the top of the inner cavity of the sealing cover 44 contacts the top of the capacitor aluminum shell, the capacitor aluminum shell is in a sealed state.

[0082] In actual application of this embodiment, the capacitor aluminum shell is moved up by the lifting platform 6, so that the top of the inner cavity of the sealing cover 44 contacts the top of the capacitor aluminum shell, so that the capacitor aluminum shell is in a sealed state. In this way, when the electrolyte is injected into the capacitor aluminum shell, the electrolyte will not splash out from the capacitor shell, thereby ensuring the accuracy of the amount of electrolyte injected into the capacitor aluminum shell. At the same time, the electrolyte isolates the external air to prevent the electrolyte from absorbing moisture in the air, thereby ensuring the effectiveness of the electrolyte.

[0083] like Fig. 9 As shown, a method for manufacturing a solid-liquid hybrid capacitor by quantitatively injecting electrolyte provided by the present invention is provided, and a liquid inlet pipe 43 is connected to the outer surface of the injection tube 4.

[0084] In actual application of this embodiment, a fixed amount of electrolyte is added into the injection tube 4 through the liquid inlet tube 43 .

[0085] like Figure 1 , Figure 2 and Fig. 9As shown, a method for manufacturing a solid-liquid hybrid capacitor with quantitative injection of electrolyte provided by the present invention is provided, wherein a controller 3 is installed on a mounting frame 1, a liquid level sensor 8 is installed on the inner wall of an injection tube 4, an electrically controlled valve 431 is installed on a liquid inlet pipe 43, the controller 3 is connected to a telescopic member 2, and the liquid level sensor 8 and the electrically controlled valve 431 are both connected to the controller 3.

[0086] In one case of this embodiment, the controller 3 is connected to an external control unit, which may be a mobile phone APP or a computer control terminal. The controller 3 controls the start and stop of the telescopic part 2 and the electric control valve 431; the liquid level sensor 8 is used to detect the amount of electrolyte in the injection tube 4.

[0087] In actual application of this embodiment, the electric control valve 431 is opened by the controller 3, and a certain amount of electrolyte is added to the injection tube 4 through the liquid inlet pipe 43. When the electrolyte level reaches the position of the liquid level sensor 8, the liquid level sensor 8 transmits a signal to the controller 3, and the electric control valve 431 is closed by the controller 3, so that the amount of electrolyte in the injection tube 4 is fixed and consistent each time; the telescopic part 2 is controlled to start and stop by the controller 3, so that the piston 22 moves downward, and the electrolyte is injected into the aluminum shell of the capacitor.

[0088] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
