Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and more specifically, to a winding machine for aluminum electrolytic capacitors. Background Technology

[0002] Capacitors are one of the most important basic electronic components in electronic engineering. They play a role in filtering, coupling, and bypassing in electronic circuits, and are widely used in communication equipment, audio-visual systems, home appliances, and instruments. The capacitor core, or element, consists of positive aluminum foil, negative aluminum foil, electrolytic paper, and leads. During manufacturing, the positive aluminum foil, negative aluminum foil, and electrolytic paper are stacked together in sequence and then wound into a roll by a winding machine. At the same time, the leads are attached to the positive or negative aluminum foil.

[0003] Currently, the winding machines for aluminum electrolytic capacitors first pull out the electrolytic paper and rotate it. During rotation, the positive or negative aluminum foil on both sides is inserted into the rotating electrolytic paper and rotates together. After rotation, the positive and negative aluminum foils are cut by an electrically controlled cutting blade. However, since the cutting is electrically controlled, it is impossible to determine whether the diameter of the cut elements is consistent, which can lead to elements with different diameters in the same batch. Moreover, since the cutting blade is electrically controlled, the operating cost of the winding machine for aluminum electrolytic capacitors is too high. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a winding machine for aluminum electrolytic capacitors, addressing the issues of inconsistency in the diameter of the cut elements and excessive operating costs.

[0005] A winding machine for aluminum electrolytic capacitors according to an embodiment of the present invention includes a housing, a support assembly disposed inside the housing, and at least two cutting assemblies embedded in the support assembly.

[0006] The support assembly includes a support plate, at least two fixing holes on both sides of the support plate, and at least two convex holes in the middle of the support plate. The support assembly is connected to the cutting assembly through two of the fixing holes and two of the convex holes.

[0007] Both cutting assemblies include a cutting element embedded in the fixing hole of the support assembly, a movable element embedded in the convex hole of the support assembly, at least two connecting ropes embedded in the cutting element extending toward the movable element, an adjusting element nested in the connecting ropes away from the cutting element, and a driving rod disposed on the adjusting element toward the movable element. The movable element drives the adjusting element to move up and down through the driving rod, and the adjusting element drives the cutting element to move through the connecting ropes.

[0008] Furthermore, the convex hole includes an elongated hole formed on the support plate at the end facing the movable member, and a serrated hole formed on the support plate at the end away from the movable member. The serrated hole facilitates positioning operations after the movable member is adjusted up and down.

[0009] Furthermore, the movable component includes a middle plate, a push plate embedded in the middle plate at the end away from the convex hole, a T-shaped plate disposed on the middle plate at the end facing the convex hole, and a locking member embedded in the T-shaped plate at the end away from the middle plate. The movable component is engaged with the convex hole of the support assembly from left to right through the locking member.

[0010] Furthermore, the engaging component includes at least two locking plates and a spring disposed between the two locking plates. The two locking plates are provided with teeth at the ends away from the spring, and the two locking plates are arranged laterally with the spring so that the two locking plates can move left and right by the spring.

[0011] Furthermore, the adjusting component includes a rotating component, a grooved plate nested in the rotating component at one end facing the support assembly, and a cover penetrating the rotating component at the end away from the grooved plate. The cover has a through hole so that the connecting rope passes through the cover and connects with the rotating component in the middle, so that the rotating component can rotate and store the connecting rope.

[0012] Furthermore, the rotating component includes a connecting post, an I-beam disposed at one end of the connecting post facing the slot plate, and a handle disposed at the end of the connecting post away from the I-beam, wherein the end of the I-beam facing the connecting post is a polygonal star shape, which is interlocked with the same end of the irregular groove provided on the slot plate.

[0013] Furthermore, the cutting component includes a second middle plate, a long plate extending through the second middle plate towards the movable component, a blade disposed on the long plate towards the connecting rope, a short plate disposed on the long plate away from the connecting rope, and an elastic member disposed on the short plate towards the long plate, so that the long plate is connected to the short plate through the elastic member.

[0014] Furthermore, the second middle plate and the first middle plate have the same structure, both having at least two grooves at both ends, so that the long plate and the push plate can move along the trajectory of the grooves.

[0015] A winding machine for aluminum electrolytic capacitors according to an embodiment of the present invention has at least the following beneficial effects:

[0016] According to the present invention, the height of the movable part should first be adjusted according to the required element diameter. After the height of the movable part is adjusted, the excess part of the connecting rope is wound into storage by the adjusting part. After storage, the cutting assembly can be used. The adjustable height of the movable part allows the operator to adjust the height of the movable part according to the required element diameter, thereby greatly increasing the application range of the cutting assembly. When the element diameter reaches the required size, the movable parts at both ends will drive the adjusting part to move together via the driving rod. When the adjusting part moves, it will drive the cutting part to move via the connecting rope. The blade of the cutting part will cut the similar positive or negative aluminum foil. Since the cutting assembly does not require power control but is controlled by the diameter of the element, it avoids the situation of different diameters of elements produced in the same batch, and also further reduces the operating cost of the winding machine.

[0033] Reference Figures 1 to 11As shown, this utility model discloses a winding machine for aluminum electrolytic capacitors, including a housing 1, a support assembly 2 disposed inside the housing 1, and at least two cutting assemblies 3 embedded in the support assembly 2. The support assembly 2 includes a support plate 21, at least two fixing holes 22 on both sides of the support plate 21, and at least two convex holes 23 in the middle of the support plate 21. The support assembly 2 is connected to the cutting assemblies 3 through the two fixing holes 22 and the two convex holes 23. Each of the two cutting assemblies 3 includes a winding machine for aluminum electrolytic capacitors. The support assembly 2 includes a cutting element 34 in the fixing hole 22, a movable element 31 embedded in the convex hole 23 of the support assembly 2, at least two connecting ropes 32 embedded in the cutting element 34 extending toward the movable element 31, an adjusting element 33 nested in the connecting ropes 32 away from the cutting element 34, and a driving rod 35 provided at the end of the adjusting element 33 toward the movable element 31. The movable element 31 drives the adjusting element 33 to move up and down through the driving rod 35, and the adjusting element 33 drives the cutting element 34 to move through the connecting ropes 32.

[0034] Furthermore, the convex hole 23 includes an elongated hole on the support plate 21 facing the movable member 31, and a serrated hole on the support plate 21 away from the movable member 31. The serrated hole facilitates the positioning operation after the movable member 31 is adjusted up and down. The movable member 31 includes a middle plate 312, a push plate 311 embedded in the middle plate 312 away from the convex hole 23, a T-shaped plate 313 disposed on the middle plate 312 facing the convex hole 23, and a locking member 314 embedded in the T-shaped plate 313 away from the middle plate 312. 31 is engaged left and right with the convex hole 23 of the support assembly 2 by the engaging member 314. The engaging member 314 includes at least two locking plates and a spring disposed between the two locking plates. The two locking plates have teeth at the ends away from the spring, and the two locking plates and the spring are arranged laterally so that the two locking plates can move left and right by the spring. The adjusting member 33 includes a rotating member 332, a grooved plate 333 nested in the end of the rotating member 332 facing the support assembly 2, and a cover 331 passing through the end of the rotating member 332 away from the grooved plate 333. The cover 331 has a through hole. This allows the connecting rope 32 to pass through the cover 331 and connect with the rotating member 332, so that the rotating member 332 can rotate and store the connecting rope 32. The rotating member 332 includes a connecting post 3322, an I-beam 3323 disposed at the end of the connecting post 3322 facing the slot plate 333, and a handle 3321 disposed at the end of the connecting post 3322 away from the I-beam 3323. The end of the I-beam 3323 facing the connecting post 3322 is a polygonal star shape, which fits into the same end as the irregular groove of the slot plate 333. The cutting member 34 includes a middle plate 3. 43, a long plate 342 passing through the end of the second middle plate 343 facing the movable member 31, a blade 341 disposed at the end of the long plate 342 facing the connecting rope 32, a short plate 344 disposed at the end of the long plate 342 away from the connecting rope 32, and an elastic member 345 disposed at the end of the short plate 344 facing the long plate 342, so that the long plate 342 is connected to the short plate 344 through the elastic member 345. The second middle plate 343 and the first middle plate 312 have the same structure, both having at least two grooves at both ends, so that the long plate 342 and the push plate 311 move along the trajectory of the grooves.

[0035] In practical implementation, firstly, as in the example... Figure 2The support assembly 2 shown has positive and negative aluminum foils placed on both sides, and a cutting assembly 3 is provided at the corresponding position of each foil. Therefore, before using the cutting assembly 3, the height of the movable part 31 must be adjusted according to the required element diameter. During adjustment, the locking plates on both sides of the engaging part 314 are pressed towards the spring. Pressing causes the movable part 31 to slide up and down in the elongated hole of the convex hole 23, allowing the height of the movable part 31 to be adjusted. After the height is adjusted, the locking plates on both sides of the engaging part 314 are released, allowing the locking plates on both sides of the engaging part 314 to... The spring's rebound force engages with the serrated hole of the convex hole 23. Since the clamping plate also has serrations, the engagement of the clamping plate with the serrated hole fixes the movable part 31 at the corresponding position in the convex hole 23, allowing the operator to adjust the height of the movable part 31. After the height of the movable part 31 is adjusted, the I-beam 3323 of the rotating part 332 is pulled out from the irregular groove of the slot plate 333 and rotated. When the rotating part 332 rotates, it drives the connecting rope 32 in the middle to rotate as well. Since the connecting rope 32 is fixedly connected to the rotating part 332, regardless of whether the rotating part 332 rotates counterclockwise or clockwise... When the needle rotates, the connecting rope 32 rotates along with it, but the number of turns of the connecting rope 32 around the rotating part 332 is reduced. The more turns the connecting rope 32 around the rotating part 332, the shorter the distance between the cutting part 34 and the adjusting part 33 connected by the connecting rope 32. The adjusting part 33 is designed to prevent the moving part 31 from being unable to move the cutting part 34 due to the connecting rope 32 being too long after the height adjustment. After the length of the connecting rope 32 is adjusted, the rotating part 332 is inserted back into its original position for fixation. Since the rotating part 332 is designed in an H-shape, the rotating part... 332 will not be completely pulled out from the irregular groove of the slot plate 333 so that the rotating part 332 can be inserted back into the irregular groove of the slot plate 333 after rotation. Both the I-beam 3323 of the rotating part 332 and the irregular groove of the slot plate 333 have a polygonal star-shaped setting, so the rotating part 332 can be embedded and fixed in the slot plate 333 at different angles so that the operator can adjust the length of the connecting rope 32 and fix it. The adjustable height of the movable part 31 allows the operator to adjust the height of the movable part 31 according to the required element diameter, thereby greatly increasing the application range of the cutting assembly 3.

[0036] As the substrate rolls larger and larger until it reaches the required diameter, the push plates 311 of the movable parts 31 at both ends move along one end of the groove of the middle plate 312. When the push plates 311 move, they drive the adjusting parts 33 to move via the driving rod 35. The adjusting parts 33, in turn, drive the long plate 342 via the connecting rope 32. When the long plate 342 moves along the groove of the middle plate 343, the blade 341 moves towards the nearest positive or negative aluminum foil. Because the blade 341 is sharp, when it passes... When the positive or negative aluminum foil is cut, the finished element is removed. The middle plate 2 343 will spring back through the elastic element 345. At the same time, the middle plate 2 343 will move the middle plate 1 312 to its original position through the connecting rope 32, the adjusting element 33 and the driving rod 35, so as to cut the next element. Since the cutting assembly 3 does not require power control but is controlled by the diameter of the element, it avoids the situation that elements produced in the same batch have different diameters, and also further reduces the operating cost of the winding machine.

[0037] In addition, in some optional embodiments of this utility model, the adjusting member 33 can extend a sliding rod towards the support plate 21, and a sliding groove is opened at the corresponding position of the support plate 21. The sliding rod is fitted into the sliding groove, so that the adjusting member 33 can move along the sliding groove trajectory of the support plate 21 through the sliding rod, thereby increasing the speed of the adjusting member 33 moving up and down.

[0038] In summary, firstly, a cutting assembly 3 is provided at the corresponding positions of the positive and negative aluminum foils. Therefore, before using the cutting assembly 3, the height of the movable part 31 should be adjusted according to the required element diameter. After the height of the movable part 31 is adjusted, the excess part of the connecting rope 32 is wound into storage by the rotating part 332 of the adjusting part 33. After storage, the cutting assembly 3 can be used. When the diameter of the element reaches the required size, the push plate 311 of the movable parts 31 at both ends will move along one end of the slide groove of the middle plate 1 312. When the push plate 311 moves, it will drive the adjusting part 33 to move together through the driving rod 35. When the adjusting part 33 moves, it will drive the long plate 342 to move through the connecting rope 32. When the long plate 342 moves along the slide groove of the middle plate 2 343, the blade 341 will cut the adjacent positive or negative aluminum foil. After cutting, the element can be removed so that the cutting assembly 3 can be used for the next element.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
