Description

Technical Field

[0001] The invention belongs to the technical field of capacitor production, in particular to a capacitor winding device. Background Art

[0002] Capacitor winding is a key step in capacitor manufacturing, especially for wound capacitors. In this process, insulating materials and electrode materials are wound into cylindrical or other shapes according to a specific design to form the basic structure of the capacitor. Capacitor winding usually uses insulating materials and conductive materials. The materials are precisely wound together according to design specifications. Aluminum foil is a common conductive material. During the processing of aluminum foil, aluminum powder particles will remain on its surface.

[0003] For example, Chinese patent CN216911552U discloses a rapid cooling device for the production of non-ferrous metal smelting rolled products, wherein the cooling pool is filled with coolant, the aluminum foil is immersed in the coolant in the cooling pool, a pair of L-shaped plates are symmetrically arranged on both sides of the cooling pool, the bottom surface of the L-shaped plate is driven by a cylinder, and the movable end of the cylinder passes through the bottom surface of the cooling pool, the L-shaped plate and the movable end of the cylinder are fixed, and a row of fixing holes are provided in the side wall of the L-shaped plate through the array, two rotating shafts are rotatably connected in the fixing holes through bearings, and conveying steel rollers are embedded and fixed on the surfaces of the two rotating shafts, the aluminum foil passes through the gap between the two conveying steel rollers and is tightly attached to the conveying steel rollers, the rotating shaft is driven by a servo motor, and the servo motor is fixed to the side of the L-shaped plate.

[0004] Relying only on coolant to separate aluminum powder from aluminum foil will result in the persistent problem of residual aluminum powder. When the aluminum foil with residual aluminum powder is rolled up, the aluminum powder will further squeeze the aluminum foil, thereby causing a depression on the surface of the aluminum foil. This depression not only affects the appearance of the aluminum foil, but more importantly, it may cause the aluminum foil to break during subsequent use, thereby directly affecting the overall quality of the capacitor produced by aluminum foil winding.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1: Figures 1 to 7 As shown, a capacitor winding device according to an embodiment of the present invention includes a mounting portion, a storage mechanism, a supporting mechanism and a cleaning mechanism.

[0037] The mounting mechanism includes a mounting plate 2 and a winding reel 1. The winding reel 1 is used to wind aluminum foil and is rotatably mounted on the side wall of the mounting plate 2. When making a capacitor, the aluminum foil needs to be wound. At this time, one end of the aluminum foil is fixed to the winding reel 1. The winding of the aluminum foil plate is achieved by rotating the winding reel 1. The winding reel 1 is driven by a motor, and the motor is arranged on the back of the mounting plate 2, which is not shown in the figure.

[0038] The storage part includes a storage box 4 and a filter box 3, both of which are fixedly mounted on the side wall of the mounting plate 2. The inner cavity of the storage box 4 is used to store cleaning liquid. During the transportation of the aluminum foil, the aluminum foil is immersed below the liquid level of the cleaning liquid inside the storage box 4, so that the oil stains and aluminum powder on the surface of the aluminum foil are decomposed by the cleaning liquid.

[0039] The cleaning liquid discharged from the storage box 4 is filtered inside the filter box 3. After the aluminum powder enters the cleaning liquid, it is filtered inside the filter box 3 to facilitate the separation and subsequent recovery of the aluminum powder and the cleaning liquid.

[0040] The supporting mechanism comprises a supporting frame 5 and a control motor 12 , and the control motor 12 is a common servo motor.

[0041] The support frame 5 is fixedly mounted on the inner wall of the storage box 4 , and the control motor 12 is fixedly mounted on the upper end surface of the support frame 5 . The support frame 5 is a U-shaped structure.

[0042] The cleaning mechanism includes a cleaning roller 10 and a mounting shaft 8 . The mounting shaft 8 is rotatably mounted on the side wall of the support frame 5 , and the rotation of the mounting shaft 8 is controlled by a control motor 12 . The support frame 5 provides mounting and support for the mounting shaft 8 and is driven by the control motor 12 .

[0043] Two mounting shafts 8 are provided, the two mounting shafts 8 are parallel to each other and are located at the upper and lower sides of the aluminum foil, and the cleaning roller 10 is arranged on the outer wall of the mounting shaft 8. When the mounting shaft 8 rotates, the cleaning roller 10 is driven to rotate.

[0044] The cleaning roller 10 is made of elastic material. In this embodiment, a common sponge material is selected, and the cleaning roller 10 is in contact with the outer wall of the aluminum foil. During the winding process of the aluminum foil, the cleaning roller 10 and the aluminum foil slide relative to each other, thereby wiping the aluminum foil to clean the aluminum foil. During the winding process, the aluminum powder and particles on the surface of the aluminum foil are prevented from affecting the winding quality.

[0045] A spiral groove is provided on the radial outer wall of the cleaning roller 10, and the spiral groove is concave inward. When the cleaning roller 10 wipes the aluminum foil, aluminum powder particles remain in the spiral groove. At this time, the cleaning roller 10 is controlled to rotate and the aluminum powder particles are controlled to be transported to one axial end of the cleaning roller 10 to discharge the aluminum powder particles, thereby preventing the aluminum powder particles from remaining in the contact area between the cleaning roller 10 and the aluminum foil, reducing the risk of scratching the aluminum foil, and effectively improving the cleaning quality during cleaning.

[0046] During the cleaning process, the lower cleaning roller 10 of the two cleaning rollers 10 is completely immersed in the cleaning liquid, and half of the upper cleaning roller 10 is immersed in the cleaning liquid.

[0047] A reciprocating screw 7 is rotatably mounted on the side wall of the support frame 5 , and a cleaning plate 17 is connected to the outer wall of the reciprocating screw 7 through threaded engagement. The reciprocating screw 7 is rotated to control the sliding of the cleaning plate 17 .

[0048] The outer wall of the cleaning plate 17 is inclined, and the bottom surface of the cleaning plate 17 is tightly fitted with the radial outer wall of the cleaning roller 10. The cleaning plate 17 is fitted with the outer wall of the cleaning roller 10 located above, and the cleaning roller 10 located above is cleaned by the reciprocating sliding of the cleaning plate 17.

[0049] The cleaning plate 17 slides along the axial direction of the cleaning roller 10 , thereby scraping off aluminum powder particles toward one axial end of the cleaning roller 10 , thereby reducing the risk of aluminum powder remaining in the depressions of the aluminum foil.

[0050] The output shaft of the control motor 12 is connected to the reciprocating screw 7 via a right-angle gear commutator, so that the reciprocating screw 7 is controlled to rotate by the control motor 12 .

[0051] The reciprocating screw 7 is connected to the mounting shaft 8 via a belt drive. The outer walls of the reciprocating screw 7 and the mounting shaft 8 are both provided with pulleys, and the two pulleys are connected by a belt, so that the mounting shaft 8 located above is driven to rotate by rotating the reciprocating screw 7.

[0052] The two installation shafts 8 are connected by gear meshing. Gears are arranged on the outer walls of the two installation shafts 8. The two gears mesh with each other. Rotating one of the installation shafts 8 controls the rotation of the other installation shaft 8.

[0053] Since the two installation shafts 8 are driven by gear meshing, the two installation shafts 8 rotate in opposite directions, and the spiral grooves on the outer walls of the two cleaning rollers 10 rotate in opposite directions, thereby controlling the two cleaning rollers 10 to discharge aluminum powder particles in one direction.

[0054] A support plate 23 is fixedly installed on the outer wall of the mounting shaft 8, and a mounting cylinder 24 is fixedly installed on the outer wall of the support plate 23. The inner wall of the cleaning roller 10 is in contact with the inner wall of the mounting cylinder 24. The mounting cylinder 24 and the cleaning roller 10 are driven to rotate synchronously by rotating the support plate 23. By controlling the rotation of the cleaning roller 10, the speed difference between the conveying speed of the aluminum foil and the rotation speed of the cleaning roller 10 is achieved, thereby maintaining the efficiency of wiping cleaning.

[0055] A connecting plate 9 is fixedly mounted on the side wall of the support frame 5 . One end of the connecting plate 9 extends to the inner cavity of the mounting tube 24 and is fixedly mounted with an elastic block 22 . The connecting plate 9 provides mounting and support for the elastic block 22 .

[0056] A cavity is provided inside the elastic block 22, and an exhaust hole is opened on the outer wall of the mounting tube 24. The elastic block 22 is made of rubber. The elastic block 22 is squeezed to discharge the air inside the elastic block 22 through the exhaust hole, and then discharged from the inside of the cleaning roller 10 to the outside, and the aluminum powder particles attached to the inside of the cleaning roller 10 are blown out, so that the aluminum powder particles in the cleaning roller 10 are discharged into the cleaning liquid, thereby improving the cleaning efficiency of the cleaning roller 10 itself, and maintaining the efficiency of wiping and cleaning the aluminum foil.

[0057] A one-way valve 25 for communicating with the exhaust hole is fixedly mounted on the outer wall of the elastic block 22 . The one-way valve 25 flows from the inside of the elastic block 22 to the outside, thereby preventing the cleaning liquid from entering the inner cavity of the elastic block 22 .

[0058] An arc-shaped piece 26 is fixedly mounted on the inner wall of the elastic block 22 . The arc-shaped piece 26 is made of elastic material and supports the inner cavity of the elastic block 22 . After squeezing the elastic block 22 , the arc-shaped piece 26 is used to assist the elastic block 22 in resetting, thereby improving the efficiency of resetting the elastic block 22 .

[0059] The radial outer wall of the mounting shaft 8 is fixedly mounted with an extrusion protrusion 21 for extruding the elastic block 22. The mounting shaft 8 rotates to control the extrusion protrusion 21 to rotate, thereby extruding the outer wall of the elastic block 22 until the extrusion protrusion 21 and the elastic block 22 are separated, at which time the elastic block 22 is reset.

[0060] An air inlet pipe connected to the inner cavity of the elastic block 22 is fixedly installed on the side wall of the connecting plate 9. The other end of the air inlet pipe extends above the liquid level of the cleaning liquid, and an electronic valve for gas entry is arranged inside. During the resetting process of the elastic block 22, air is introduced through the air inlet pipe so as to control the discharge of the gas inside the elastic block 22 when the elastic block 22 is squeezed again, thereby realizing recoil cleaning of the cleaning roller 10.

[0061] A liquid inlet pump 28 and a liquid discharge pump 27 are fixedly mounted on the inner wall of the filter box 3. The liquid inlet pump 28 and the liquid discharge pump 27 are common micro water pumps.

[0062] The input end of the liquid inlet pump 28 is connected to the external cleaning liquid storage chamber, and the input end of the liquid inlet pump 28 is communicated with the inner cavity of the storage box 4 to control the cleaning liquid to enter the storage box 4.

[0063] The input end of the drainage pump 27 is connected to the inner cavity of the storage box 4, and the output end of the drainage pump 27 extends to the inner cavity of the filter box 3 and is fixedly installed with a filter layer 29. The cleaning liquid containing aluminum powder in the storage box 4 is discharged by the drainage pump 27. During the discharge, the aluminum powder is filtered through the filter layer 29.

[0064] The liquid level balance inside the storage box 4 is maintained by the cooperation of the liquid inlet pump 28 and the liquid discharge pump 27, while the aluminum powder content in the cleaning liquid in the storage box 4 is reduced. In addition, the bubbles generated by the exhaust through the elastic block 22 disturb the cleaning liquid, thereby controlling the stirring of the aluminum powder, so as to facilitate the uniform discharge of the aluminum powder mixed with the cleaning liquid and prevent the precipitation of the aluminum powder.

[0065] A support frame 6 is fixedly mounted on the upper end of the storage box 4 , and a sliding plate 13 is slidably mounted on the inner wall of the support frame 6 . The sliding plate 13 can be lifted and slid along the inner wall of the support frame 6 .

[0066] An upper scraper plate 15 is fixedly installed on the bottom surface of the sliding plate 13, and a lower scraper plate 16 is fixedly installed on the inner wall of the storage box 4. The upper scraper plate 15 and the lower scraper plate 16 are both made of rubber. The bottom surface of the aluminum foil fits with the lower scraper plate 16. The sliding plate 13 is slid and adjusted until the upper scraper plate 15 fits with the aluminum foil, so that water stains on the surface of the aluminum foil can be scraped off when the aluminum foil is transported.

[0067] The upper scraper plate 15 and the lower scraper plate 16 are both arranged to be inclined toward the traveling direction of the aluminum foil, so as to prevent the upper scraper plate 15 and the lower scraper plate 16 from hindering the conveyance of the aluminum foil.

[0068] The upper end surface of the sliding plate 13 is rotatably mounted with a control shaft 14 , which penetrates the carrier frame 6 and is connected to the carrier frame 6 by means of internal and external threads. The control shaft 14 is rotated to control the sliding of the sliding plate 13 , thereby achieving sliding adjustment of the upper scraper plate 15 .

[0069] A support roller 11 for supporting the aluminum foil is rotatably mounted on the upper end surface of the storage box 4 so that the aluminum foil can extend below the level of the cleaning liquid inside the storage box 4 .

[0070] Embodiment 2: Figures 8 to 10 As shown in Comparative Example 1, another embodiment of the present invention is: A carrying plate 20 is fixedly mounted on the side wall of the mounting plate 2 . Two carrying plates 20 are provided and are respectively located on both sides of the aluminum foil. During the transportation process of the aluminum foil, the aluminum foil passes between the two carrying plates 20 .

[0071] An exhaust pump 19 is fixedly mounted on the upper end surface of the carrier plate 20 , and an exhaust pipe 18 is fixedly mounted on the output end of the exhaust pump 19 . When the exhaust pump 19 discharges gas, the gas is discharged through the exhaust pipe 18 .

[0072] The inner wall of the carrier plate 20 is provided with a discharge hole 33, the inner cavity of the discharge hole 33 is connected with the inner cavity of the exhaust pipe 18, and a plurality of discharge holes 33 are evenly arranged along the outer wall of the carrier plate 20. When the exhaust pipe 18 is exhausted, the discharge holes 33 spray air, thereby increasing the air flow speed on the surface of the aluminum foil, thereby achieving further drying of the aluminum foil after wiping.

[0073] The discharge hole 33 is arranged obliquely, and the inclination direction of the discharge hole 33 is opposite to the conveying direction of the aluminum foil, so that air can be blown toward the rear of the aluminum foil to prevent residual water stains from splashing in the direction of the winding part.

[0074] A fixing plate 31 is fixedly mounted on the side wall of the mounting plate 2 , a mounting block 30 is elastically mounted on the bottom surface of the fixing plate 31 , a spring is provided on the bottom surface of the fixing plate 31 , and the other end of the spring is fixedly connected to the outer wall of the mounting block 30 .

[0075] A wiping layer 32 is fixedly installed on the bottom surface of the mounting block 30. The outer wall of the wiping layer 32 fits with the surface of the aluminum foil. The wiping layer 32 is a breathable non-woven fabric. The elastic force of the spring pushes the wiping layer 32 to have a real-time tendency to fit with the outer wall of the aluminum foil. After blowing and cleaning, the outer wall of the aluminum foil is wiped again to maintain cleaning efficiency.

[0076] A guide rod 34 is fixedly installed on the upper end surface of the mounting block 30. At least two guide rods 34 are provided. The guide rods 34 penetrate the fixed plate 31, and the outer wall of the guide rod 34 slides in contact with the inner wall of the fixed plate 31 to achieve a sliding connection between the mounting block 30 and the fixed plate 31, thereby limiting the sliding trajectory of the mounting block 30.

[0077] The mounting block 30 is provided with a cavity inside, and an air guide pipe is fixedly installed on the outer wall of the mounting block 30 . A hard pipe connected with the air guide pipe is fixedly installed on the input end of the exhaust pump 19 , and the hard pipe is a common copper pipe.

[0078] The hard tube and the air duct are perpendicular to each other. When air is taken in at the input end of the exhaust pump 19, the air flow speed at the connection between the air duct and the hard tube is increased, thereby controlling the air suction on the bottom surface of the mounting block 30, and cooperating with the wiping layer 32 to wipe, further improving the cleaning efficiency.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
