Description

Technical Field

[0002] A capacitor is an electronic component that can store electrical charge and temporarily store electrical energy; simply put, it is a "miniature energy storage warehouse" in a circuit.

[0003] In the existing aluminum electrolytic capacitor production process, a multi-stage negative pressure permeation liquid injection device is required to inject liquid into the capacitor shell and then complete the encapsulation. During this process, the sealing gasket at the bottom of the upper injection tube moves down and contacts the top of the lower capacitor shell to complete the seal.

[0020] This invention discloses a multi-stage negative pressure permeation type aluminum electrolytic capacitor liquid injection device to solve the above-mentioned problems.

[0021] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Please see Figure 1-6A multi-stage negative pressure permeation type aluminum electrolytic capacitor liquid injection device includes: base 1, pressure cap 2, sealing ring 3, liquid injection pipe 4, permeation membrane, connecting plate 5, air extraction pipe 6, valve 7, turntable 8, motor 10, straightening assembly, ejection assembly, and lifting assembly. The base 1 is used to assemble the liquid injection device. The pressure cap 2 is set above the base 1. The sealing ring 3 is fixedly connected to the bottom of the pressure cap 2. The liquid injection pipe 4 is fixedly connected to the pressure cap 2. The permeation membrane is axially and equidistantly arranged inside the liquid injection pipe 4. The connecting plate 5 is fixedly connected to the upper part of the liquid injection pipe 4. The vacuum pipe 6 is fixedly connected to the pressure cap 2. The valve 7 is set inside the liquid injection pipe 4. The valve 7 is a solenoid valve. The liquid injection pipe 4 is externally connected to a liquid injection mechanism (not shown in the figure). The liquid injection mechanism is a liquid injection mechanism that can provide liquid inside the capacitor shell in the prior art. The vacuum pipe 6 is externally connected to a vacuum pump (not shown in the figure). The vacuum pump is a vacuum pump in the prior art. A turntable 8 is mounted on a base 1, and several placement slots 9 are arranged around the turntable 8. When the placement slot 9 rotates to the position directly below the sealing ring 3, it is coaxial with the sealing ring 3. A suction pipe 6 is connected through the pressure cap 2. The suction pipe 6 is used to connect the placement slot 9 to perform negative pressure suction. A motor 10 is fixed inside the base 1 and is used to drive the turntable 8 to rotate. The motor 10 is a motor whose output shaft can be locked after stopping. A correction component is mounted on the turntable 8 and can correct the position of the turntable 8 when the output shaft of the motor 10 deviates, so that the sealing ring 3 is aligned with the placement slot 9. An ejection component is mounted on the base 1 and is used to eject the capacitor in the placement slot 9. A lifting component is mounted on the base 1 and is used to drive the connecting plate 5 to lift and lower.

[0023] In use, the capacitor casing is placed in the placement slot 9. The lifting assembly drives the connecting plate 5 to lower the liquid injection tube 4, the pressure cap 2, and the sealing ring 3, so that the sealing ring 3 abuts against the top of the capacitor casing to complete the seal. Then, the vacuum equipment works in conjunction with the air extraction tube 6 to evacuate the inside of the capacitor casing to make it negative pressure. Then, the liquid injection mechanism works to inject liquid into the liquid injection tube 4. The liquid is stored in the liquid injection tube 4. Then, the liquid injection stops and the valve 7 is opened. Under negative pressure, the capacitor casing draws the liquid through the permeation membrane into the capacitor casing. After the drawing is completed, the lifting assembly drives the connecting plate 5 to reset, realizing the reset of the liquid injection tube 4 and the pressure cap 2, completing one liquid injection. Then, the output shaft of the motor 10 drives the turntable 8 to rotate a certain angle to move the next capacitor casing under the pressure cap 2. The above operation is repeated to inject liquid. The liquid injection process is consistent with the process of the multi-stage negative pressure permeation aluminum electrolytic capacitor liquid injection equipment in the prior art. Due to long-term use, the output shaft of motor 10 will deviate, causing the capacitor housing on turntable 8 to fail to align with the sealing ring 3 under cover 2 after rotating to a certain angle and stopping, thus affecting the subsequent sealing effect. Therefore, when the output shaft of motor 10 stops rotating the turntable 8 at a certain angle, the position of the turntable 8 is corrected by the correction component. This ensures that even if the output shaft of motor 10 deviates, the capacitor housing and the sealing ring 3 under the pressure cap 2 are still aligned, thus ensuring the subsequent sealing effect and the smooth progress of the subsequent liquid injection operation.

[0024] In one specific implementation, reference is made to... Figure 1-6 The correction components include: vertical plate 11, adjustment components, and locking components; The vertical plate 11 is fixed around the outside of the turntable 8. The adjustment component is set on the pressure cover 2 for adjusting the position of the vertical plate 11. The locking component is set on the output shaft of the motor 10 for locking the turntable 8.

[0025] When the motor 10 rotates, it rotates the turntable 8 in conjunction with the locking assembly. When the output shaft of the motor 10 deviates, the turntable 8 also deviates, and the vertical plate 11 deviates. At this time, the pressure cover 2 moves down, and the locking assembly releases the lock on the turntable 8, allowing the turntable 8 to rotate relative to the output shaft of the motor 10. Subsequently, the position of the vertical plate 11 is adjusted in conjunction with the adjustment assembly, causing the turntable 8 to rotate and adjust accordingly until the capacitor housing in the placement slot 9 on the turntable 8 is aligned with the sealing ring 3 under the pressure cover 2. When the pressure cover 2 is reset, the locking assembly locks the turntable 8 again, allowing the output shaft of the motor 10 to continue driving the turntable 8 to rotate.

[0026] In one specific implementation, reference is made to... Figure 6 The adjustment assembly includes: a sloping plate 12 and a straight plate 13. The top of the straight plate 13 is connected to the pressure cap 2, and the bottom of the straight plate 13 is connected to the sloping plate 12. Every two sloping plates 12 form a pair, and the two sloping plates 12 are symmetrically arranged along the midline of the vertical distance between the pair of straight plates 13. When the vertical plate 11 moves along the sloping plate 12 between the pair of straight plates 13, both sides of the vertical plate 11 can contact the inner side of the straight plate 13.

[0027] As the pressure cap 2 descends, it brings down the straight plate 13 and the inclined plate 12. After the inclined surface of the inclined plate 12 comes into contact with the vertical plate 11, it squeezes the vertical plate 11 and causes the turntable 8 to deflect. Finally, the vertical plate 11 can enter between the pair of straight plates 13. At this time, the adjustment of the turntable 8 is completed, so that the capacitor shell and the sealing ring 3 are aligned and sealed smoothly.

[0028] In one specific implementation, reference is made to... Figure 2-6 The locking components include: base 14, card slot, card block 17, and drive component; The base 14 is fixedly connected to the top of the output shaft of the motor 10. The lower part of the turntable 8 is rotatably installed in the base 14. The slot is set in the lower part of the turntable 8. The card block 17 is slidably installed on the base 14. One end of the card block 17 extends into the slot. The drive assembly is set on the base 14 and is used to drive the card block 17 to move horizontally into or out of the slot.

[0029] The drive component drives the card block 17 to move away from the card slot until it leaves the card slot, at which point the lock on the turntable 8 is released. Conversely, the drive block 17 resets and enters the card slot, thus locking the turntable 8.

[0030] In one specific implementation, reference is made to... Figure 4-6 The drive components include: an iron rod 18, a spring 19, an electromagnet 20, a controller (not shown in the figure), and a switch 21; The iron rod 18 is fixedly connected to one end of the locking block 17, the spring 19 is sleeved on the outside of the iron rod 18, the electromagnet 20 is fixedly connected to the base 14, and can attract the iron rod 18 when energized. The controller is set on the turntable 8, and the switch 21 is set on the inside of the inclined plate 12, which can cooperate with the controller to energize or de-energize the electromagnet 20.

[0031] When the inclined plate 12 descends, the switch 21 is pressed against the vertical plate 11. The remote controller controls the electromagnet 20 to be energized and made magnetic, so that the attracting rod 18 moves with the locking block 17. At the same time, the spring 19 is compressed and deformed, the locking block 17 leaves the slot, the inclined plate 12 resets, the controller controls the electromagnet 20 to be de-energized and made magnetic, at which time the spring 19 resets and moves the locking block 17 back into the slot.

[0032] In one specific implementation, reference is made to... Figure 6 The bottom of the pressure cover 2 is provided with a horizontal groove, and a lead screw 22 is rotatably installed in the horizontal groove. A straight plate 13 is threaded on the outside of the lead screw 22. The texture directions on both sides of the lead screw 22 are opposite. A motor 23 is fixedly installed on one side of the pressure cover 2. One end of the output shaft of the motor 23 is fixedly connected to one end of the lead screw 22.

[0033] As the pressure cap 2 rises and resets, the output shaft of the motor 23 reverses and rotates the lead screw 22, causing the pair of straight plates 13 to separate. This prevents the straight plates 13 from rubbing against the vertical plate 11 when they rise, thus avoiding unnecessary wear. After the pressure cap 2 resets, the output shaft of the motor 23 rotates forward, and vice versa, thus resetting the straight plates 13.

[0034] In one specific implementation, reference is made to... Figure 2 The ejector assembly includes: ring plate 24, ejector rod 25, ring 26, and electric push rod 27; The ring plate 24 is set on the base 1, the top rod 25 is fixedly fixed around the ring plate 24 at equal intervals, the top of the top rod 25 extends into the interior of the placement groove 9, the ring 26 is rotatably installed on the bottom of the ring plate 24, and the electric push rod 27 is fixedly connected to the interior of the base 1, with the top of the electric push rod 27 connected to the ring 26.

[0035] When the turntable 8 rotates, it rotates the push rod 25 and the ring plate 24. After the liquid is injected, the electric push rod 27 is activated to extend and push the ring 26, the ring plate 24, and the push rod 25 to rise and push the capacitor shell in the placement slot 9 out for easy removal.

[0036] In one specific implementation, reference is made to... Figure 1-2 The lifting assembly includes: cylinder 28 and bracket 29; Cylinder 28 is fixedly connected to the upper part of base 1, bracket 29 is fixedly connected to the bottom of cylinder rod of cylinder 28, and bracket 29 is fixedly connected to connecting plate 5.

[0037] The starting cylinder 28 extends its cylinder rod, causing the bracket 29 and connecting plate 5 to descend; conversely, the cylinder rod shortens, causing the connecting plate 5 to rise and reset.

[0038] In one specific implementation, reference is made to... Figure 5 The slot is composed of a rectangular slot 15 and an inclined surface 16, with the inclined surface 16 symmetrically arranged on the inner walls of both sides of the rectangular slot 15.

[0039] When the locking rod 17 is reset, due to the correction of the turntable 8, the inclined surface 16 will correspond to the end position of the locking rod 17. The locking rod 17 presses the inclined surface 16 and rotates against the turntable 8, so that the locking rod 17 can finally enter the rectangular groove 15.

[0040] In one specific implementation, reference is made to... Figure 1 The number and position of the vertical plates 11 and the placement slots 9 are corresponding.

[0041] This allows the position of the placement slot 9 to be corrected by correcting the vertical plate 11.

[0042] Working principle: During use, the capacitor shell is placed in the placement slot 9. The lifting assembly drives the connecting plate 5 to lower the liquid injection tube 4, the pressure cap 2, and the sealing ring 3, so that the sealing ring 3 abuts against the top of the capacitor shell to complete the seal. Then, the vacuum equipment works in conjunction with the air extraction tube 6 to evacuate the inside of the capacitor shell to make it a negative pressure state. Then, the liquid injection mechanism works to inject liquid into the liquid injection tube 4. The liquid is stored in the liquid injection tube 4. Then, the liquid injection stops and the valve 7 is opened. Under the negative pressure state, the capacitor shell draws the liquid through the permeation membrane into the capacitor shell. After the drawing is completed, the lifting assembly drives the connecting plate 5 to reset, realizing the reset of the liquid injection tube 4 and the pressure cap 2, completing one liquid injection. Then, the output shaft of the motor 10 drives the base 14, the clamping rod 17, and the turntable 8 to rotate a certain angle, moving the next capacitor shell to the bottom of the pressure cap 2. The above operation is repeated to inject liquid. Due to long-term use, the output shaft of motor 10 will deviate, causing the capacitor housing on turntable 8 to fail to align with the sealing ring 3 under cover 2 after rotating to a certain angle and stopping, thus affecting the subsequent sealing effect. As the pressure cap 2 descends, it lowers the straight plate 13 and the inclined plate 12. When the inclined plate 12 descends, the switch 21 comes into contact with the vertical plate 11 and is pressed. The remote controller then energizes the electromagnet 20, making it magnetic. This causes the attracting rod 18 to move along with the locking block 17, while simultaneously compressing the spring 19, causing it to deform. The locking block 17 then leaves the slot, allowing the turntable 8 to rotate freely. As the pressure cap 2 descends, it lowers the straight plate 13 and the inclined plate 12. After the inclined surface of the inclined plate 12 comes into contact with the vertical plate 11, it presses the vertical plate 11, causing the turntable 8 to deflect. Finally, the vertical plate 11 can enter the pair of straight plates. Between 13, the adjustment of turntable 8 is completed to ensure that the capacitor shell is aligned with the sealing ring 3 for a smooth seal. When the pressure cover 2 rises and resets, after the inclined plate 12 is above the vertical plate 11, the controller controls the electromagnet 20 to de-energize it and make it lose its magnetism. At this time, the spring 19 resets, along with the locking block 17. When the locking rod 17 resets, due to the correction of turntable 8, the inclined surface 16 will correspond to the end position of the locking rod 17. The locking rod 17 presses the inclined surface 16 and pushes the turntable 8 to rotate, so that the locking rod 17 can finally enter the rectangular groove 15 to complete the locking of turntable 8. As the pressure cap 2 rises and resets, the output shaft of the motor 23 reverses and rotates the lead screw 22, causing the pair of straight plates 13 to separate. This prevents the straight plates 13 from rubbing against the vertical plate 11 when they rise, thus avoiding unnecessary wear. After the pressure cap 2 resets, the output shaft of the motor 23 rotates forward, and vice versa, thus resetting the straight plates 13.
