Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil winding, in particular to an aluminum foil winding device for electrolytic capacitors and a method thereof. Background Art

[0002] Capacitors are electronic components used to store and release electrical charge. They are widely used in various electrical and electronic devices, such as wireless communications or household appliances. Winding is an important step in the manufacturing process, which determines the performance of the capacitor and the reliability of its application.

[0003] At present, the existing capacitor aluminum foil winding device is in use. After the stacked electrode sheets and diaphragm materials are neatly connected, they are automatically wound by the main winding roller, and each sub-roller compacts them for tape conveying. During the winding process, a certain tension is applied to the diaphragm to ensure the neatness between the positive electrode sheets, diaphragms, and negative electrode sheets. However, the tension in the process will cause the diaphragm to be stretched in the tape conveying direction, which will not only cause the diaphragm to severely squeeze the conductive foil electrode sheets, causing defects such as wrinkles between the electrode sheets and the diaphragms, but also cause the battery cells to deform after winding. The deformed battery cells have poor appearance flatness, which reduces the winding effect. In the actual workshop, flying chips such as cutting materials and certain impurities will float. During winding, due to electrostatic adsorption, the quality of use after winding will be affected.

[0015] The present invention also provides a method for winding aluminum foil for electrolytic capacitors, which specifically comprises the following steps:

[0016] S1: First, the personnel turn on the switch of the winding drive and the machine pump barrel from the external controller. After the winding drive is turned on, the main winding roller is driven to rotate to initially connect the aluminum foil and the diaphragm, and then the winding operation is performed. At this time, the rotation of the main winding roller drives the first pulley on one side to rotate, and the first pulley drives the other second pulley to rotate in the same direction through the belt, so as to drive the traction roller to rotate. Then, the rotation of the traction roller can drive the turntable to rotate. After the turntable rotates, it drives the rotating core to pull the pull rod sleeve to continuously swing along the directional trajectory. When the pull rod sleeve moves, it drives the machine pump barrel to move. When the machine pump barrel moves, it drives the collection net cover to slide on the surface of the guide foil. At the same time, driven by the machine pump barrel, the elastic strip plate also contacts and slides with the surface of the guide foil, so as to keep the angle control of the collection net cover and the guide foil. Under the operation of the machine pump barrel, the debris or foreign matter on the surface of the guide foil is sucked from the collection net cover for collection, and then discharged into the winding drive through the conveying hose;

[0017] S2: At the same time, the rotation of the traction roller drives the second gear to rotate clockwise, and the second gear drives the interlocking gear meshing with it to rotate in the opposite direction, so that the other interlocking gear is driven to rotate counterclockwise and then drives the first gear to rotate clockwise, so that the rotating drum is driven to rotate, and the diagonally arranged distribution film produces an effect of pushing the guide foil to both sides when the rotating drum rotates;

[0018] S3: When the distribution film and the collection screen operate on the guide foil, the guide foil drives the diaphragm to contact the lower support plate. After the lower support plate is subjected to force, the pressure rod therein moves. After the pressure rod moves, the pressure plate slides in the sleeve. When the pressure plate slides, it squeezes the second spring, so that when the membrane driving component and the impurity removal component operate, they can cooperate and interact with each other;

[0019] S4: Then, as the main winding roller is winding, the wound aluminum foil continuously contacts the tightening seat cover, which can compact the winding tightness when contacting, and can also drive the tightening seat cover to move according to the amount of winding. After the tightening seat cover moves, it drives the push rod to move. When the push rod moves, it drives the sliding sleeve to slide on the outer surface of the cross column. When the sliding sleeve slides, it will slowly contact the first spring.

[0020] S5: The rotation of the traction roller can also drive the driven roller to rotate, which can assist in traction of the diaphragm and the guide foil to avoid bending deformation caused by excessive pulling force on the winding material. When the main winding roller is wound to a suitable size, the winding driver automatically turns on the switch of the second gear, and the extended end of the second gear extends to push the linkage block to move on the chassis. After the linkage block moves, the top groove can push the triangular head to move in the inner groove of the cutting sleeve. After the triangular head moves, it drives the cutting knife to slide outward, and the winding material is completely cut by cooperating with the knife groove. The hydraulic push rod is reset. When the cutting is completed, the linkage block drives the heat sealing head to just contact the cutting edge of the winding material, and heat is supplied under the action of the heat pump, so that the wound material is sealed to make it heat-sealed and formed. After rotating the support shaft frame, remove and replace the main winding roller and perform subsequent operations, and the cycle is repeated.

[0021] Beneficial effects of the present invention:

[0022] The aluminum foil winding device and method for electrolytic capacitors described in the present invention drive the second gear to rotate clockwise through the rotation of the traction roller, and drive the linkage gear to rotate in the opposite direction, so that the other linkage gear is driven to rotate counterclockwise to drive the first gear to rotate clockwise, and the distribution film is driven to push the two sides of the pole piece after the rotation of the drum. When the distribution film and the collecting net cover are operated on the guide foil, the diaphragm is subjected to force after being in contact with the lower support plate, and the pressure rod therein is driven to move. After the pressure rod moves, the pressure plate is driven to slide in the sleeve to squeeze the second spring. As the winding progresses, the main winding roller forms a battery core in contact with the tightening seat sleeve. When the tightening seat sleeve is in contact, the winding core can be compacted. The tightening seat sleeve is slightly lowered to drive the push rod to move, so that the sliding sleeve slides on the horizontal column and is squeezed by the first spring. The traction roller drives the driven roller to rotate, which can play an auxiliary traction role on the diaphragm and the guide foil pole piece, which is beneficial to prevent the diaphragm from being elongated due to excessive tension during winding, avoid mutual squeezing, ensure the neat running of the diaphragm and the pole piece, and improve the overall winding effect.

[0023] The rotation of the main winding roller drives the first pulley on one side to rotate, and the first pulley drives the other second pulley to rotate in the same direction through the belt, so as to drive the traction roller to rotate. Then, the rotation of the traction roller can drive the turntable to rotate. After the turntable rotates, it drives the rotating core to pull the pull rod sleeve to swing continuously along the directional trajectory. When the pull rod sleeve moves, it drives the machine pump barrel to move. When the machine pump barrel moves, it drives the collecting mesh cover to slide on the surface of the guide foil. At the same time, driven by the machine pump barrel, the elastic strip also contacts and slides with the surface of the guide foil, so as to keep the angle control of the collecting mesh cover and the guide foil. Under the operation of the machine pump barrel, the debris or foreign matter on the surface of the guide foil is sucked in from the collecting mesh cover for collection, and then discharged into the winding drive through the conveying hose, so that when the membrane driving component and the impurity removal component are operated, they can cooperate with each other, which is beneficial to the surface cleaning of the winding material when winding the aluminum foil, ensuring the neatness of the winding and the winding quality.

An adjusting component 552 is arranged on the upper surface of the winding base 1, and a tightening seat cover 22 is arranged above the winding base 1.

An impurity removal component 554 is slidably arranged on the upper surface of the foil guide 5. The adjusting component 552 includes two horizontal columns 14 fixedly connected to the upper end of the winding base 1, And a plurality of sliding sleeves 16 movably mounted on both ends of the horizontal column 14, both ends of the horizontal column 14 are movably mounted with a first spring 15 used in conjunction with the two sliding sleeves 16 on each side, the outer surfaces of each of the two sliding sleeves 16 are rotatably connected with a push rod 17, and the plurality of push rods 17 are rotatably connected with the tightening seat sleeve 22, the impurity removal component 554 includes a collecting mesh cover 25 slidably arranged on the upper surface of the guide foil 5, and a machine pump barrel 24 connected to the collecting mesh cover 25, and a pull rod sleeve 27 is rotatably mounted on both ends of the machine pump barrel 24, and a turntable 10 is fixedly mounted on both ends of the traction roller 20, and a rotating core 32 is connected to the outer surfaces of the two rotating disks 10, and the pull rod sleeve 27 is rotatably connected with the rotating core 32, and one end of the main winding roller 11 is fixedly mounted with a first pulley 19, and the traction roller 20 ... One end of the roller 20 is fixedly sleeved with a second pulley 47 connected to the first pulley 19 through a belt, and a pump barrel 24 is installed between the two pull rod sleeves 27 for common rotation. The outer surface of the pump barrel 24 is fixedly connected with an elastic strip 48, and one end of the outer surface of the pump barrel 24 is fixedly connected with a conveying hose 2, and the conveying hose 2 is connected to the winding driver 3. One end of the traction roller 20 is fixedly sleeved with a second gear 28, and the upper part of the mounting frame 12 is rotatably installed with two meshing linkage gears 31, one of which is meshed with the first gear 26, and the other linkage gear 31 is meshed with the second gear 28. After the winding driver 3 is started and operated, the main winding roller 11 is driven to rotate to initially connect the aluminum foil with the diaphragm for winding operation.At this time, the rotation of the main winding roller 11 drives the first pulley 19 on one side to rotate, and the first pulley 19 drives the other second pulley 47 to rotate in the same direction through the belt, so that the traction roller 20 is driven to rotate. Then, the rotation of the traction roller 20 can drive the turntable 10 to rotate. After the turntable 10 rotates, it drives the rotating core 32 to pull the rod sleeve 27 to continuously swing along the directional trajectory. When the rod sleeve 27 moves, it drives the pump barrel 24 to move. When the pump barrel 24 moves, it drives the collecting net cover 25 to slide on the surface of the guide foil 5. At the same time, the elastic strip 48 also slides in contact with the surface of the foil guide 5 under the drive of the pump barrel 24, so as to keep the angle of the collecting screen 25 and the foil guide 5 under control. Under the operation of the pump barrel 24, the debris or foreign matter on the surface of the foil guide 5 is sucked from the collecting screen 25 for collection, and then discharged into the winding driver 3 through the conveying hose 2, which is beneficial to the surface cleaning of the winding material during the winding operation of the aluminum foil, and prevents wrinkles and bulging after winding. In the application of capacitors, excessive pressure is easy to cause damage, affecting the capacitor In use, the second gear 28 is driven to rotate clockwise under the rotation of the traction roller 20. After the second gear 28 rotates, it drives the interlocking gear 31 meshing with it to rotate in the opposite direction, so that the other interlocking gear 31 is driven to rotate counterclockwise and then drives the first gear 26 to rotate clockwise, so that the rotating drum 23 is driven to rotate. Under the rotation of the rotating drum 23, the obliquely arranged distribution film 21 produces an effect of pushing the guide foil (5) to both sides, thereby controlling the gap between the diaphragm 4 and the guide foil 5, avoiding the occurrence of bubbles and affecting the winding quality. When the distribution film 21 and the collection screen 25 operate on the foil guide 5, the foil guide 5 drives the diaphragm 4 to collide with the lower support plate 7. After the lower support plate 7 is subjected to force, the pressure rod 37 therein is driven to move. After the pressure rod 37 moves, the pressure plate 36 is driven to slide in the sleeve 34. When the pressure plate 36 slides, it squeezes the second spring 35, so that when the film driving component 551 and the impurity removal component 554 operate, they can interact with each other and maintain a certain supporting force to ensure that the aluminum foil material does not produce quality problems such as paint peeling and scratches during the winding process.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the auxiliary component 553 includes a lower bracket 29 fixedly connected to one end of the winding drive 3, and a positioning rod 6 rotatably connected to the inner side of the lower bracket 29, the outer surface of the positioning rod 6 is rotatably sleeved with a lower support plate 7, a plurality of sleeves 34 are fixedly connected to the upper surface of the lower bracket 29, a plurality of sleeves 34 are movably provided with a pressure plate 36 inside, a plurality of sleeves 34 are provided with a second spring 35 used in conjunction with the pressure plate 36 inside, a plurality of pressure rods 37 are symmetrically rotatably installed on the lower surface of the lower support plate 7, the pressure rod 37 passes through the sleeve 34 and is movably connected to the pressure plate 36, the slitting component 555 includes a bottom frame 30 fixedly connected to the inner surface of the tightening seat sleeve 22, and a bottom frame 30 at one end thereof. The cutting sleeve 33 is fixedly connected, and a cutting knife 43 is movably arranged inside the cutting sleeve 33. A triangular head 42 is fixedly installed at the bottom end of the cutting knife 43. A knife groove 46 used in conjunction with the cutting knife 43 is arranged inside the cutting sleeve 33. A hydraulic push rod 18 is obliquely installed inside the chassis 38. A linkage block 40 is fixedly connected to the protruding end of the hydraulic push rod 18.

When the tightening seat sleeve 22 contacts, the winding tightness can be compacted, and the tightening seat sleeve 22 can be driven to move according to the amount of winding. After the tightening seat sleeve 22 moves, it drives the push rod 17 to move. When the push rod 17 moves, it drives the sliding sleeve 16 to slide on the outer surface of the cross column 14. When the sliding sleeve 16 slides, it will slowly contact the first spring 15.

The rotation of the traction roller 20 can also drive the driven roller 8 to rotate, which can play an auxiliary traction role on the diaphragm 4 and the guide foil 5 to avoid the pulling force of the winding material. When the main winding roller 11 is wound to a suitable size, the winding drive 3 automatically turns on the switch of the second gear 28, and the protruding end of the second gear 28 extends to push the linkage block 40 to move on the chassis 38. After the linkage block 40 moves, the top groove 44 can push the triangular head 42 to move in the inner groove of the cutting sleeve 33. After the triangular head 42 moves, it drives the cutting knife 43 to slide outward, and the winding material is completely cut by cooperating with the knife groove 46. The hydraulic push rod 18 is reset. When the cutting is completed, the linkage block 40 drives the heat sealing head 41 to just contact the cutting edge of the winding material, and heat is supplied under the action of the heat pump 39, so that the edge of the wound material is sealed to make it heat-sealed and formed.

[0038] The embodiment of the present invention also provides a method for winding aluminum foil for electrolytic capacitors, and the specific working principle includes the following steps:

[0039] S1: First, the personnel turn on the switch of the winding drive 3 and the pump barrel 24 from the external controller. After the winding drive 3 is turned on, the main winding roller 11 is driven to rotate to initially connect the aluminum foil and the diaphragm, and then the winding operation is performed. At this time, the rotation of the main winding roller 11 drives the first pulley 19 on one side to rotate, and the first pulley 19 drives the other second pulley 47 to rotate in the same direction through the belt, so that the traction roller 20 is driven to rotate. Then, the rotation of the traction roller 20 can drive the turntable 10 to rotate, and the turntable 10 drives the rotating core 32 to pull the pull rod sleeve 27 continuously. The machine pump barrel 24 is driven to move when the pull rod sleeve 27 moves, and the machine pump barrel 24 drives the collecting screen 25 to slide on the surface of the foil guide 5. At the same time, the elastic strip 48 is also driven by the machine pump barrel 24 to slide on the surface of the foil guide 5, so as to keep the angle of the collecting screen 25 and the foil guide 5 controlled. Under the operation of the machine pump barrel 24, the debris or foreign matter on the surface of the foil guide 5 is sucked from the collecting screen 25 for collection, and then discharged into the winding driver 3 through the conveying hose 2, which is beneficial to the surface cleaning of the winding material when winding the aluminum foil;

[0040] S2: At the same time, the rotation of the traction roller 20 drives the second gear 28 to rotate clockwise, and the second gear 28 drives the interlocking gear 31 meshing with it to rotate in the opposite direction, so that the other interlocking gear 31 is driven to rotate counterclockwise and then drives the first gear 26 to rotate clockwise, so that the rotating drum 23 is driven to rotate. Under the rotation of the rotating drum 23, the obliquely arranged distribution film 21 produces an effect of pushing the guide foil 5 to both sides, thereby controlling the gap between the diaphragm 4 and the guide foil 5 to avoid bubbles and affect the winding quality;

[0041] S3: When the distribution film 21 and the collection net cover 25 operate on the guide foil 5, the guide foil 5 drives the diaphragm 4 to contact the lower support plate 7. After the lower support plate 7 is subjected to force, it drives the pressure rod 37 therein to move. After the pressure rod 37 moves, it drives the pressure plate 36 to slide in the sleeve 34. When the pressure plate 36 slides, it squeezes the second spring 35, so that when the membrane driving component 551 and the impurity removal component 554 operate, they can interact with each other, maintain a certain supporting force, and maintain a certain elastic supporting force to avoid damage to the electrode and the diaphragm;

[0042] S4: Then, with the winding operation of the main winding roller 11, the wound aluminum foil continuously contacts the tightening seat cover 22. When the tightening seat cover 22 contacts, the winding tightness can be compacted, and the tightening seat cover 22 can be driven to move according to the amount of winding. After the tightening seat cover 22 moves, the push rod 17 is driven to move. When the push rod 17 moves, the sliding sleeve 16 is driven to slide on the outer surface of the cross column 14. When the sliding sleeve 16 slides, it will slowly contact the first spring 15. The tightness between the tightening seat cover 22 and the winding material can be adjusted according to the amount of winding, thereby improving the tightness between the electrolyte and the electrode sheet.

[0043] S5: The rotation of the traction roller 20 can also drive the driven roller 8 to rotate, which can assist in traction of the diaphragm 4 and the guide foil 5 to avoid bending deformation caused by excessive pulling force of the winding material. When the main winding roller 11 is wound to a suitable size, the winding driver 3 automatically opens the switch of the second gear 28, and the extended end of the second gear 28 extends to push the linkage block 40 to move on the chassis 38. After the linkage block 40 moves, the top groove 44 can push the triangular head 42 to move in the inner groove of the cutting sleeve 33. After the triangular head 42 moves, it drives the cutting knife 43 to slide outward, and the winding material is completely cut by cooperating with the knife groove 46. The hydraulic push rod 18 is reset. When the cutting is completed, the linkage block 40 drives the heat sealing head 41 to just contact the cutting edge of the winding material, and heat is supplied under the action of the heat pump 39, so that the wound material is sealed to make it heat-sealed and formed. After rotating the support shaft frame 13, the main winding roller 11 is removed and replaced, and then subsequent operations are performed, and the cycle is repeated.

2. A method for winding aluminum foil for electrolytic capacitors, characterized in that: Using the aluminum foil winding device for electrolytic capacitors as described in claim 1, the method specifically comprises the following steps: S1: First, the personnel turn on the switches of the winding drive (3) and the pump barrel (24) from the external controller. After the winding drive (3) is turned on, the main winding roller (11) is driven to rotate to initially connect the aluminum foil and the diaphragm and then perform the winding operation. At this time, the rotation of the main winding roller (11) drives the first pulley (19) on one side to rotate. The first pulley (19) drives the other second pulley (47) to rotate in the same direction through the belt, so that the traction roller (20) is driven to rotate. Then, the rotation of the traction roller (20) can drive the turntable (10) to rotate. After the turntable (10) rotates, it drives the rotating core (3) 2) Pulling the rod sleeve (27) to continuously swing along a directional trajectory, the rod sleeve (27) drives the pump barrel (24) to move when the rod sleeve (27) moves, and the pump barrel (24) drives the collecting mesh cover (25) to slide on the surface of the guide foil (5). At the same time, driven by the pump barrel (24), the elastic strip (48) also contacts and slides with the surface of the guide foil (5), thereby maintaining the angle control between the collecting mesh cover (25) and the guide foil (5). Under the operation of the pump barrel (24), foreign matter on the surface of the guide foil (5) is sucked from the collecting mesh cover (25) for collection, and then discharged into the winding drive (3) through the conveying hose (2); S2: At the same time, the rotation of the traction roller (20) drives the second gear (28) to rotate clockwise, and the second gear (28) drives the interlocking gear (31) meshing with it to rotate in the opposite direction, so that the other interlocking gear (31) is driven to rotate counterclockwise, and then drives the first gear (26) to rotate clockwise, so that the rotating drum (23) is driven to rotate, and the obliquely arranged distribution film (21) produces an effect of pushing the guide foil (5) to both sides when the rotating drum (23) rotates; S3: When the distribution film (21) and the collection screen (25) operate on the guide foil (5), the guide foil (5) drives the diaphragm (4) to contact the lower support plate (7). After the lower support plate (7) is subjected to force, it drives the pressure rod (37) therein to move. After the pressure rod (37) moves, it drives the pressure plate (36) to slide in the sleeve (34). When the pressure plate (36) slides, it squeezes the second spring (35), so that when the membrane driving component (551) and the impurity removal component (554) operate, they can cooperate with each other; S4: Then, as the main winding roller (11) is wound, the wound aluminum foil continuously contacts the tightening seat cover (22), and the tightening seat cover (22) moves, driving the push rod (17) to move. When the push rod (17) moves, it drives the sliding sleeve (16) to slide on the outer surface of the cross column (14), and when the sliding sleeve (16) slides, it contacts the first spring (15); S5: The rotation of the traction roller (20) can also drive the driven roller (8) to rotate, which can play an auxiliary traction role on the diaphragm (4) and the guide foil (5), thereby preventing the winding material from being bent and deformed due to excessive pulling force. When the main winding roller (11) is wound to a suitable size, the winding driver (3) automatically opens the switch of the second gear (28), and the extended end of the second gear (28) extends to push the linkage block (40) to move on the chassis (38). After the linkage block (40) moves, the top groove (44) can push the triangular head (42) on the cutting sleeve The inner groove of the box (33) moves, and the triangular head (42) moves to drive the cutting knife (43) to slide outward, and the wound material is completely cut by cooperating with the knife groove (46). The hydraulic push rod (18) is reset. When the cutting is completed, the linkage block (40) drives the heat sealing head (41) to just contact the cutting edge of the wound material, and heat is sent in under the action of the heat pump (39), so that the wound material is sealed and heat-sealed. After rotating the support shaft frame (13), the main winding roller (11) is removed and replaced, and then subsequent operations are carried out, and the cycle is repeated.
