Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production, and more specifically, to a high-performance capacitor sealed terminal cover plate and a sealing method therefor. Background Art

[0002] A capacitor is composed of two conductors close to each other with a layer of non-conductive insulating medium in between. It can store electrical energy and has the characteristics of charging, discharging, passing alternating current, and blocking direct current. Capacitors are one of the most widely used electronic components in electronic devices, [1] and are widely used in aspects such as blocking direct current and passing alternating current, coupling, bypassing, filtering, tuning circuits, energy conversion, and control in circuits.

[0003] In the patent "201010291159.5", when installing and sealing with an aluminum shell, after determining the position, corresponding to the positions of the sealing card slot and the sealing rubber ring on the outer side of the aluminum shell, indentations are rolled out from the outside to the inside. The indentations on the aluminum shell press the sealing rubber ring, making the capacitor airtight, and the terminal cover plate is fixed by the sealing indentations. Then, the edge of the aluminum shell is pressed and rolled from the outside to the inside and from top to bottom along the edge of the aluminum shell to press the sealing rubber ring, making the sealing position of the capacitor also airtight. However, if the position of the sealed terminal cover plate is not locked during the sealing process, the sealing will fail.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a high-performance capacitor sealed terminal cover plate and a sealing method therefor are provided, in order to achieve a more practical value. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a high-performance capacitor sealed terminal cover plate and a sealing method therefor to solve the above problems.

[0006] The purpose and effect of the high-performance capacitor sealed terminal cover plate and the sealing method therefor of the present invention are achieved by the following specific technical means:

[0007] A high-performance capacitor sealing terminal cover plate and its sealing method, including a housing and a capacitor. A positioning device and a sealing device are installed inside the housing. The positioning device consists of a side wall positioning component and a central pressing component. The side wall positioning component includes two rotating shafts respectively rotatably installed inside the housing. The same ends of the two rotating shafts are connected by a synchronous belt. A driving motor is arranged at the middle position of the synchronous belt. Two groups of screw threads with opposite helix directions are provided on the outer wall of the rotating shaft. Threaded seats are threadedly connected to the two groups of screw threads on the outer wall of the rotating shaft. A roller is rotatably arranged between two corresponding threaded seats. The central pressing component includes a mounting block slidably connected to the housing. A chute for cooperating with the housing is provided on the outer wall of the mounting block. The mounting block is located at the middle position between two coaxial threaded seats. A first hydraulic telescopic rod is fixedly installed at the middle position of the mounting block. A limiting plate is installed at the end of the first hydraulic telescopic rod. Guide rods are slidably connected to both sides of the mounting block. A return spring for cooperating with the mounting block is sleeved on the outer wall of the guide rod. The guide rods are fixed to the outer wall of the housing. An adjusting plate is fixedly installed on the outer wall of each threaded seat. A groove for cooperating with the adjusting plate is provided on the outer wall of the mounting block. One side of the adjusting plate close to the groove is inclined. The adjusting plates located coaxially are arranged staggeredly. A receiving groove for cooperating with another adjusting plate is provided on the outer wall of the threaded seat. The cross-section of the adjusting plate is a right trapezoid. The shortest side surface of the adjusting plate is fixedly connected to the threaded seat. The directions of the screw threads on the outer walls of the two rotating shafts can be adjusted accordingly according to the actual situation. A roller for cooperating with the adjusting plate is rotatably arranged inside the groove;

[0008] In practical applications, before use, the driving motor rotates forward, driving the two rotating shafts to rotate. The forward rotation of the rotating shafts drives the two threaded seats to move in opposite directions, so that the corresponding threaded seats drive the rollers to move, making the two rollers move away from each other. Then, the staff places the capacitor to be processed in the middle position of the limiting plate. Subsequently, the two first hydraulic telescopic rods start to work, making the upper and lower limiting plates contact the upper and lower ends of the capacitor. Then, the driving motor rotates in reverse, and the two rollers move closer to each other and contact the outer wall of the capacitor, thus completing the positioning. At the same time, the device is provided with adjusting plates, and one side of the adjusting plate is inclined. Therefore, when the diameter of the capacitor is smaller, the two rollers are closer to each other. The mounting block is slidably connected to the adjusting plate, so that the mounting block approaches the roller along the inclined surface on one side of the adjusting plate, ensuring that when sealing, the first hydraulic telescopic rod on the outer wall of the mounting block is located at the central axis position of the capacitor, thus avoiding the deviation of the limiting plate during the rotary sealing of the sealing device.

[0009] Further, the sealing device includes a pressing rod, and two ends of the outer wall of the pressing rod are respectively provided with second hydraulic telescopic rods. The upper ends of the second hydraulic telescopic rods are fixedly connected to the top of the housing. One end of the pressing rod is fixedly provided with a rotating rod, and a worm gear is fixedly installed on the outer wall of the rotating rod. A worm is arranged on one side of the worm gear for cooperating with the worm gear. The worm is rotatably connected to the housing, and one end of the worm is connected to the output shaft of the first motor. The outer wall of the pressing rod is slidably connected with a hemming block and a grooving block. Locking components are respectively arranged inside the hemming block and the grooving block. The cross section of the pressing rod is rectangular;

[0010] In practical applications, after positioning is completed, the second hydraulic telescopic rods extend, enabling the hemming blocks to contact the grooving blocks and the capacitors respectively. Subsequently, the first motor operates. The output shaft of the first motor drives the worm to rotate. The worm drives the worm gear to rotate. The worm gear drives the pressing rod to rotate through the rotating rod. The pressing rod drives the grooving block and the capacitor to rotate. The grooving block and the capacitor drive the capacitor to rotate synchronously during the rotation process. Thus, after the grooving block and the capacitor rotate one week along the outer wall of the capacitor, sealing is completed.

[0011] Further, the limiting plate is rotatably connected to the first hydraulic telescopic rod. At the same time, the limiting plate and the first hydraulic telescopic rod form a detachable mechanism. A cavity is opened inside the limiting plate. A rubber pad is pasted at the lower end of the limiting plate. First air holes that cooperate with each other are respectively opened on the rubber pad and the outer wall of the limiting plate. The cavity of the limiting plate is connected to the first air pump through a first hose;

[0012] In practical applications, after the limiting plate contacts the upper and lower ends of the capacitor, the first air pump starts to operate. The first air pump starts to inhale air to straighten the end cover of the capacitor and lock the height of the end cover at the same time, avoiding the failure of capacitor sealing due to incorrect end cover height during sealing.

[0013] Further, the locking component includes a T-shaped sliding rod slidably arranged inside the grooving block. A second spring is installed at the upper end of the sliding rod. A fixing block is fixedly arranged at the lower end of the sliding rod. Protective patterns that cooperate with each other are respectively opened on the outer wall of the fixing block that contacts the pressing rod. The locking component inside the hemming block has the same structure as the locking component inside the grooving block;

[0014] In practical applications, through the movable grooving block and hemming block, capacitors with different heights can be sealed, thereby improving the practicability of the device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Before use, the driving motor rotates forward, driving two rotating shafts to rotate. The forward rotation of the rotating shafts drives two threaded seats to move in opposite directions. Accordingly, the corresponding threaded seats drive the rollers to move, causing the two rollers to move away from each other. Thus, the staff can place the capacitor to be processed in the middle position of the limiting plate. Subsequently, two first hydraulic expansion rods start to work, causing the upper and lower limiting plates to contact the upper and lower ends of the capacitor. Then, the driving motor rotates in reverse, and the two rollers move closer to each other and contact the outer wall of the capacitor, thereby completing the positioning. At the same time, the device is provided with an adjusting plate, and one side of the adjusting plate is inclined. Therefore, when the diameter of the capacitor is smaller, the two rollers are closer to each other. The mounting block is slidably connected to the adjusting plate, so the mounting block approaches the roller along the inclined surface on one side of the adjusting plate, ensuring that when sealing, the first hydraulic expansion rod on the outer wall of the mounting block is located at the central axis position of the capacitor, thus preventing the limiting plate from shifting during rotary sealing by the sealing device.

[0017] 2. After the limiting plate contacts the upper and lower ends of the capacitor, the first air pump starts to work. The first air pump starts to suck air to straighten the end cap of the capacitor and lock the height of the end cap simultaneously, preventing the end cap from having an incorrect height during sealing and causing the sealing of the capacitor to fail.

[0031] Embodiment:

[0032] As shown in the attached Figure 1 to the attached Figure 7 figure:

[0033] The present invention provides a high-performance capacitor sealing terminal cover plate and its sealing method, including a housing 1 and a capacitor 2. A positioning device 3 and a sealing device 4 are installed inside the housing 1. The positioning device 3 consists of a side wall positioning component and a central pressing component. The side wall positioning component includes two rotating shafts 306 respectively rotatably installed inside the housing 1. The same ends of the two rotating shafts 306 are connected by a synchronous belt, and a driving motor is arranged at the middle position of the synchronous belt. Two groups of thread segments with opposite helix directions are provided on the outer wall of the rotating shaft 306. Threaded seats 304 are threadedly connected to the two groups of thread segments on the outer wall of the rotating shaft 306. A roller 308 is rotatably arranged between two corresponding threaded seats 304. The central pressing component includes a mounting block 301 slidably connected to the housing 1. A sliding groove 3012 for cooperating with the housing 1 is provided on the outer wall of the mounting block 301. The mounting block 301 is located at the middle position between two coaxial threaded seats 304. A first hydraulic telescopic rod 302 is fixedly installed at the middle position of the mounting block 301. A limiting plate 303 is installed at the end of the first hydraulic telescopic rod 302. Guide rods 307 are slidably connected to both sides of the mounting block 301. A return spring 309 for cooperating with the mounting block 301 is sleeved on the outer wall of the guide rod 307. The guide rod 307 is fixed to the outer wall of the housing 1. An adjusting plate 305 is fixedly installed on the outer wall of each threaded seat 304. A groove 3011 for cooperating with the adjusting plate 305 is provided on the outer wall of the mounting block 301. The side of the adjusting plate 305 close to the groove 3011 is inclined. The adjusting plates 305 located coaxially are arranged staggeredly. A receiving groove 3041 for cooperating with the other adjusting plate 305 is provided on the outer wall of the threaded seat 304. The cross-section of the adjusting plate 305 is a right trapezoid. The shortest side surface of the adjusting plate 305 is fixedly connected to the threaded seat 304. The directions of the thread segments on the outer walls of the two rotating shafts 306 can be adjusted accordingly according to the actual situation. A roller for cooperating with the adjusting plate 305 is rotatably arranged inside the groove 3011;

[0034] In practical applications, before use, the drive motor rotates forward to drive the two rotating shafts 306 to rotate. The forward rotation of the rotating shafts 306 drives the two threaded seats 304 to move in opposite directions. Accordingly, the corresponding threaded seats 304 drive the rollers 308 to move, causing the two rollers 308 to move away from each other. Then, the staff places the capacitor 2 to be processed in the middle position of the limiting plate 303. Subsequently, the two first hydraulic telescopic rods 302 start to work, causing the upper and lower limiting plates 303 to contact the upper and lower ends of the capacitor 2. Then, the drive motor rotates in reverse, and the two rollers 308 move closer to each other and contact the outer wall of the capacitor 2, thus completing the positioning. At the same time, the device is provided with an adjusting plate 305, and one side of the adjusting plate 305 is inclined. Therefore, when the diameter of the capacitor 2 is small, the two rollers 308 move closer to each other. The mounting block 301 is slidably connected to the adjusting plate 305. Accordingly, the mounting block 301 approaches the roller 308 along the inclined surface on one side of the adjusting plate 305, ensuring that when sealing, the first hydraulic telescopic rod 302 on the outer wall of the mounting block 301 is located at the central axis position of the capacitor 2, thus preventing the limiting plate 303 from shifting during the rotary sealing of the sealing device 4.

[0035] Among them, the sealing device 4 includes a pressing rod 401. At both ends of the outer wall of the pressing rod 401, second hydraulic telescopic rods 403 are respectively installed. The upper ends of the second hydraulic telescopic rods 403 are fixedly connected to the top of the housing 1. One end of the pressing rod 401 is fixedly installed with a rotating rod 402. On the outer wall of the rotating rod 402, a worm gear 406 is fixedly installed. On one side of the worm gear 406, a worm that cooperates with the worm gear 406 is provided. The worm is rotatably connected to the housing 1. One end of the worm is connected to the output shaft of the first motor. The outer wall of the pressing rod 401 is slidably connected with a hemming block 405 and a grooving block 404. Locking components 5 are respectively arranged inside the hemming block 405 and the grooving block 404. The cross-section of the pressing rod 401 is rectangular;

[0036] In practical applications, after positioning is completed, the second hydraulic telescopic rod 403 extends, causing the hemming block 405 to contact the grooving block 404 and the capacitor 2 respectively. Subsequently, the first motor works, and the output shaft of the first motor drives the worm to rotate. The worm drives the worm gear 406 to rotate. The worm gear 406 drives the pressing rod 401 to rotate through the rotating rod 402. The pressing rod 401 drives the grooving block 404 and the capacitor 2 to rotate. During the rotation of the grooving block 404 and the capacitor 2, the capacitor 2 rotates synchronously. Therefore, after the grooving block 404 and the capacitor 2 rotate one week along the outer wall of the capacitor 2, the sealing is completed.

[0037] Among them, the limit plate 303 is rotatably connected to the first hydraulic telescopic rod 302. At the same time, a detachable mechanism is provided between the limit plate 303 and the first hydraulic telescopic rod 302. A cavity is provided inside the limit plate 303. A rubber pad is pasted on the lower end of the limit plate 303. The rubber pad and the outer wall of the limit plate 303 are respectively provided with first air holes that cooperate with each other. The cavity of the limit plate 303 is connected to the first air pump through a first hose;

[0038] In practical applications, after the limit plate 303 contacts the upper and lower ends of the capacitor 2, the first air pump starts to work. The first air pump starts to suck air to straighten the end cap of the capacitor 2, and at the same time locks the height of the end cap to prevent the end cap height from being incorrect during sealing, resulting in the failure of sealing the capacitor 2.

[0039] Among them, the locking component 5 includes a T-shaped sliding rod 501 slidably arranged inside the pressing groove block 404. A second spring 502 is installed at the upper end of the sliding rod 501. A fixing block 503 is fixedly arranged at the lower end of the sliding rod 501. The outer walls of the fixing block 503 and the pressing rod 401 in contact with each other are respectively provided with protective patterns that cooperate with each other. The locking component 5 inside the folding edge block 405 has the same structure as the locking component 5 inside the pressing groove block 404;

[0040] In practical applications, through the movable pressing groove block 404 and folding edge block 405, the capacitor 2 with different heights can be sealed, thereby improving the practicability of the device.

[0041] The specific usage method and function of this embodiment:

[0042] Before use, the driving motor rotates forward to drive the two rotating shafts 306 to rotate. The forward rotation of the rotating shafts 306 drives the two threaded seats 304 to move in opposite directions. Accordingly, the corresponding threaded seats 304 drive the rollers 308 to move, so that the two rollers 308 move away from each other. Then the staff places the capacitor 2 to be processed in the middle position of the limit plate 303. Subsequently, the two first hydraulic telescopic rods 302 start to work, so that the upper and lower limit plates 303 contact the upper and lower ends of the capacitor 2. Subsequently, the driving motor rotates in reverse, and the two rollers 308 approach each other and contact the outer wall of the capacitor 2, thus completing the positioning. At the same time, the device is provided with an adjusting plate 305. One side of the adjusting plate 305 is inclined. Therefore, when the diameter of the capacitor 2 is smaller, the two rollers 308 are closer to each other. The mounting block 301 is slidably connected to the adjusting plate 305. Accordingly, the mounting block 301 approaches the roller 308 along the inclined surface on one side of the adjusting plate 305, so as to ensure that when sealing, the first hydraulic telescopic rod 302 on the outer wall of the mounting block 301 is located at the central axis position of the capacitor 2, thereby preventing the limit plate 303 from shifting when the sealing device 4 rotates for sealing.

[0043] The embodiments of the present invention are provided by way of example and description, and are not exhaustive or limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
