Description

Technical Field

[0001] This utility model relates to the field of foil production, specifically to a foil winding device. Background Technology

[0002] Electrolytic foil is a product made from specially treated high-purity aluminum foil that has undergone electrochemical or chemical etching to increase its surface area, followed by electrochemical formation to create an oxide film (aluminum oxide) on the surface. It is mainly used in the manufacture of aluminum electrolytic capacitors. The manufacturing process of electrolytic foil generally includes: pretreatment, etching, anodizing and electrolyte impregnation, winding, and packaging.

[0003] The winding process of electrolytic foil typically uses winding rollers to quickly obtain rolled foil for convenient transportation and storage. However, the unloading process of the rolled electrolytic foil from the winding device is relatively complex. Usually, after ensuring that the aluminum foil winding process is completed, the drive motor needs to be turned off to ensure that the winding roller stops rotating. Then, some winding devices require lifting the end of the winding roller with the bearing sleeve first. By changing the angle, the locking block and the sleeve shaft are disengaged before the winding roller can be removed. Some winding rollers also need to be unloaded from the fixed groove. In other highly automated equipment, another empty winding device can be moved to the working position by pushing the winding device on the track for the next round of winding. However, these unloading methods for electrolytic foil winding devices require relatively complex processes or expensive equipment operation and manual assistance, so they cannot be completed quickly or require high investment, affecting the efficiency and cost of electrolytic foil production and packaging. Utility Model Content

[0004] This invention addresses the problems of complex unloading processes, high equipment investment, and high manpower consumption in existing electroformed foil winding devices, which lead to low efficiency and high cost in electroformed foil production and packaging. It provides a foil winding device that can quickly unload foil, thereby improving the efficiency of foil production and packaging.

[0006] A foil winding device, comprising:

[0007] Mounting rack; and

[0008] The winding mechanism has a rotating shaft rotatably mounted on the mounting frame; the rotating shaft consists of a first rod, a second rod, and a third rod from one end to the other, with the first rod and the second rod hinged together.

[0009] The rotating shaft is axially movable. When the hinge point of the first rod and the second rod is engaged in the mounting frame, the second rod and the third rod are coupled through a connector, and the first rod, the second rod, and the third rod can rotate synchronously. When the hinge point of the first rod and the second rod disengages from the mounting frame, the connector and the third rod disengage and rotate downward around the hinge point with the second rod, so that the wound foil can be released from below.

[0010] Furthermore, the mounting frame has a lower box body, and an exit port communicating with the upper part of the mounting frame is provided on the upper part of the box body, so that when the wound foil is released, it can enter the box body through the exit port.

[0011] Furthermore, a roller for winding foil is provided in the middle of the rotating shaft. The roller includes an inner roller and an outer roller sleeved outside the inner roller. When the wound foil is detached, the outer roller detaches together with the foil.

[0012] Furthermore, a snap-fit ​​element is slidably disposed inside the inner roller, and a cylindrical portion is disposed on the connector; when the hinge point of the first rod and the second rod is engaged in the mounting frame, the snap-fit ​​element fixes the inner roller and the outer roller relative to each other through a buckle at one end; when the hinge point of the first rod and the second rod is disengaged from the mounting frame, the cylindrical portion can abut against and push the snap-fit ​​element to release the buckle, and the inner roller and the outer roller separate.

[0013] Furthermore, the mounting bracket has a frame, on which an arc-shaped slide rail is provided, and the connector has a sliding part that is slidably embedded in the slide rail; when the connector and the third rod are disengaged, the sliding part can slide along the slide rail.

[0017] Furthermore, a second bearing is provided in the second mounting hole on one side of the mounting bracket, and a second insertion hole is provided in the middle of the inner ring of the second bearing. The other end of the fourth insertion block is inserted into the second insertion hole.

[0018] Furthermore, a first cylinder and a second cylinder are respectively provided on the mounting bracket at both ends of the rotating shaft, and the output end of the second cylinder is rotatably connected to the outer end of the third rod through a first bearing.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model features a winding mechanism mounted on a mounting frame. Through a multi-segment rotating shaft design, the movable hinge point between the first and second rods allows them to rotate synchronously around the shaft's axis or relative to each other.

[0038] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0039] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0040] Example 1

[0041] In the existing technology, the process of unloading the coiled electrolytic foil from the electrolytic foil winding device is relatively complicated. It usually requires multiple steps such as moving the winding device, loosening the insert block, and unloading the winding roller. These unloading methods require relatively complicated equipment operation or manual assistance, so they cannot be completed quickly, which affects the production and packaging efficiency of electrolytic foil.

[0042] This embodiment provides a foil winding device for winding produced fused foil and enabling rapid unloading, thereby improving production and packaging efficiency. Please refer to... Figures 1-10 The foil winding device mainly includes: a mounting frame 100 and a winding mechanism 200 disposed on the mounting frame 100.

[0043] The mounting frame 100 is the support structure of the foil winding device in this embodiment, used to position the other components so that they can cooperate with each other to work. For example... Figure 1 , Figure 2As shown, the mounting frame 100 mainly consists of a lower housing 140 and an upper frame 120. The housing 140 is roughly rectangular in shape, and a collection cylinder 142 is placed inside its internal cavity for collecting rolled chemically formed foil. The frame 120 is roughly rectangular in shape, and a first mounting hole 121 and a second mounting hole 127 are respectively provided on the upper parts of two opposite side walls of the frame 120. The first mounting hole 121 and the second mounting hole 127 are arranged opposite each other, and a bearing is provided in both mounting holes for mounting a rotatable winding mechanism 200. Furthermore, between the side wall and the bottom wall on the side of the second mounting hole 127 on the frame 120, a slide rail 122 with an arc-shaped trajectory is provided, and the track surface of the slide rail 122 has a groove with an arc-shaped cross-section, the central angle of the arc-shaped cross-section of the groove being greater than 90°. Meanwhile, a mounting platform 126 is provided on the outer side wall of the side connected to the slide rail 122. The mounting platform 126 is a rectangular plate extending outward, used to install components for adjusting the position of the winding mechanism 200. In addition, at the bottom of the frame 120 below the slide rail 122, an exit port 123 is provided, which communicates with the box 140 below, allowing the rolled chemically formed foil collected in the upper frame 120 to quickly enter the box 140 for collection.

[0044] The winding mechanism 200 is used to guide the formed foil at the end of the production line into rolls for subsequent packaging, storage, and transportation. For example... Figures 1-6As shown, the winding mechanism 200 mainly includes a rotating shaft rotatably mounted on the frame 120, and a roller body disposed in the middle of the rotating shaft. The rotating shaft is horizontally disposed between the two side walls of the frame 120, and is divided into a first rod 210, a second rod 220 and a third rod 230 from one end to the other. The first rod 210 has symmetrical first inserts 212 on both sides of its outer side facing the frame 120. The first inserts 212 on both sides extend axially toward the middle of the first rod 210. At the middle position, a limiting ring 214 is provided on the outer sleeve of the first rod 210. A hinge shaft 216 perpendicular to the axial direction of the first rod 210 is provided at the inner side of the first rod 210 facing the frame 120 for hinged connection with the second rod 220. A second insert 218 is provided between the hinge shaft 216 and the limiting ring 214. The second inserts 218 are also symmetrically arranged on both sides of the first rod 210. The rod segment on the first rod 210 containing the second inserts 218 is inserted into the bearing in the first mounting hole 121, so that the first rod 210 can move axially and rotate relative to the frame 120. Next, a hinge plate 222 with a hinge hole is provided at one end of the second rod 220 connected to the first rod 210. The hinge plate 222 is rotatably sleeved on the hinge shaft 216, allowing the two rods to rotate relative to each other with the connection point as the hinge point. The middle part of the second rod 220 is used to set the roller. The other end of the second rod 220 has symmetrical third inserts 224 on both sides of its side, and the third inserts 224 on both sides extend towards the middle of the second rod 220 along the axial direction. At the same time, the third rod 230 is provided at the other end of the second rod 220. The third rod 230 has symmetrical fourth inserts 232 on both sides of its side along the axial direction. The third rod 230 is inserted into the bearing in the second mounting hole 127 through the fourth inserts 232, so that the third rod 230 can move and rotate relative to the frame 120. Furthermore, the second rod 220 and the third rod 230 are coupled together by a connector 240 sleeved on the two rods. The connector 240 is roughly divided into a cylindrical portion 242 at one end and a sliding portion 244 at the other end, and a first insertion hole 246 is provided in the middle of the connector 240 along the axial direction of the rotating shaft, through which the cylindrical portion 242 and the sliding portion 244 pass in sequence. The cylindrical portion 242 is roughly cylindrical in shape and is used to insert into the roller body in the middle of the second rod 220 when the rotating shaft moves axially. The sliding portion 244 is roughly spherical in shape, and one side can abut against the inner side of the side wall of the frame 120, preventing the connector 240 from passing through the second mounting hole 127. The sliding portion 244 is slidably embedded in the groove of the slide rail 122, and can rotate or slide along the slide rail 122, but cannot disengage from the groove. When the second rod 220 rotates downward, the sliding of the sliding portion 244 in the groove can guide the movement direction of the second rod 220.In addition, the two ends of the first insertion hole 246 are respectively used to insert the rod segment on the second rod 220 where the third insertion block 224 is located and the third rod 230 with the fourth insertion block 232, so that the second rod 220 and the third rod 230 can be rotated synchronously axially through the transmission of the connector 240, or they can be pulled out from the connector 240 for separation.

[0045] Simultaneously, this embodiment also includes a drive mechanism composed of a motor and a reducer for driving the rotating shaft to rotate; and a first cylinder 410 and a second cylinder 420 for controlling the axial movement of the rotating shaft. Both the motor and the reducer are housed within a housing 130 on the outer side wall of the frame 120 near the first rod 210. A rotation output end 132 of the reducer extends from the upper part of the housing 130. The rotation output end 132 has a insertion hole in its center that mates with the first insertion block 212 of the first rod 210. The first rod 210 can move axially along the rotating shaft within the mounting hole and can be driven to rotate around the rotating shaft axially via the rotation output end 132. Furthermore, the first cylinder 410 is located on the upper part of the housing 130, with its output end facing the outward end of the first rod 210, for pushing the first rod 210 to move axially. The second cylinder 420 is mounted on the mounting platform 126 on the outer side wall of the frame 120 near the third rod 230. The output end of the second cylinder 420 is positioned opposite the outer end of the third rod 230, and the output end of the second cylinder 420 and the outer end of the third rod 230 are rotatably connected by the first bearing 510. The third rod 230 is located inside the inner ring of the first bearing 510, and the output end of the second cylinder 420 is connected to the outer ring of the first bearing 510. The second cylinder 420 is used to control the axial movement of the third rod 230.

[0046] One specific working method of this embodiment is as follows:

[0047] When the foil needs to be wound up, the output end of the first cylinder 410 retracts, and the output end of the second cylinder 420 extends, causing the entire rotating shaft to move towards the side of the first cylinder 410. At this time, the limiting ring 214 of the first rod 210 is locked inward on the side of the rotating output end 132, and the outward end of the first rod 210 does not contact the output end of the first cylinder 410. The hinge point between the inward end of the first rod 210 and the second rod 220 enters the first mounting hole 121, preventing the two rods from moving along the hinge axis 216. The first rod 210 rotates along the shaft axially, driven by the output end of the second cylinder 420, and abuts against the second rod 220, applying axial force to keep the entire shaft compact. Then, the motor is started, and the output end 132 drives the first rod 210 to rotate axially along the shaft, driving the second rod 220 through the hinge point, and then the third rod 230 through the connector 240, causing the entire shaft to rotate synchronously and collecting the formed foil onto the roller. When unloading is required after winding is complete, the output end of the first cylinder 410 extends, and the output end of the second cylinder 420 retracts, causing the entire rotating shaft to move towards the side of the second cylinder 420. At this time, the outward end of the first rod 210 is abutted by the output end of the first cylinder 410, and the limiting ring 214 of the first rod 210 is locked on the outward side of the first mounting hole 121 of the frame 120. The hinge point between the inward end of the first rod 210 and the second rod 220 disengages from the first mounting hole 121, allowing the two rods to move along the hinge. Shaft 216 rotates relative to each other, and the third rod 230 is driven by the output end of the second cylinder 420 to disengage from the first insertion hole 246 of the connector 240, so that the connector 240 can slide downward along the slide rail 122; then, the connector 240 slides downward along the slide rail 122, while driving the second rod 220 to rotate downward around the hinge point to the vertical direction, so that the aluminum foil wound on the roller can disengage downward from the second rod 220 and enter the box 140 below from the exit hole 123, and be collected by the collection cylinder 142.

[0048] In summary, in this embodiment, the foil winding device has a winding mechanism 200 on the mounting frame 100. Through the multi-segment rotating shaft design of the winding mechanism 200, and utilizing the movable hinge point between the first rod 210 and the second rod 220, the two can rotate synchronously around the axis of the rotating shaft or rotate relative to each other around the hinge axis. Furthermore, by utilizing the connector 240 sleeved between the second rod 220 and the third rod 230, the two can rotate synchronously around the axis of the rotating shaft or disengage relative to each other. This allows the rotating shaft of the winding mechanism 200 to quickly disengage from the drive shaft direction, facilitating the unloading of the wound foil. This solves the problems of complex unloading methods, high equipment investment, and high manpower consumption in the existing electroforming foil winding device, which result in low efficiency and high cost in the production and packaging of electroforming foil.

[0049] like Figures 7-9 As shown in the figure, in this embodiment, the roller body is mainly divided into an inner roller 250 and an outer roller 260 sleeved outside the inner roller 250. The inner roller 250 also has a locking member 270 inside, which can lock the inner roller 250 and the outer roller 260 together. The locking member 270 is slidably disposed within a slide rail 252 inside the inner roller 250. One end of the locking member 270 is a disc-shaped pressing head 272, disposed within the first section of the slide rail 252. The first section of the slide rail has a circular cross-section and is coaxially arranged with the rotating shaft. The size of the first section of the slide rail is adapted to the cylindrical portion 242 of the connecting member 240. The center of the snap-fit ​​component 270 has six annularly arranged sliding rods 274. The six sliding rods 274 are arranged around the central axis of the rotating shaft. Each sliding rod 274 is divided into a first sliding section 275 connecting the pressing head 272 and a second sliding section 276 on the other side. The first sliding section 275 has a circular cross-section and is set in the six second-section slides of the slide 252 that it is adapted to. The second sliding section 276 has a rectangular cross-section and is set in the six third-section slides of the slide 252 that it is adapted to. The cross-sectional area of ​​the second sliding section 276 is smaller than that of the first sliding section 275, thereby forming a stepped surface between the second-section slides and the third-section slides that are adapted to each of them. A spring 254 is connected between the stepped surface and the first sliding section 275. The other ends of the six second sliding sections 276 extend out of the slide 252 and are connected to a snap-fit ​​ring 277. The snap-fit ​​ring 277 extends outward in a radial direction with six buckles 278. Meanwhile, one end of the outer roller 260 is provided with six matching slots 262 for engaging with six buckles 278. Before the formed foil is unloaded, under the action of the spring 254, the buckles 278 engage in the slots 262, fixing the inner roller 250 and the outer roller 260 relatively. When the rotating shaft moves to the side of the second cylinder 420, the cylindrical part 242 of the connector 240 inserts into the first section of the slide 252, abutting against the pressing head 272 of the snap fastener 270, pushing the snap fastener 270 to the other side and compressing the spring 254, thereby separating and releasing the buckle 278 at the other end of the snap fastener 270 from the slot 262. The outer roller 260 can then easily detach from the inner roller 250, allowing the formed foil wound on the outer roller 260 to easily enter the lower housing 140.

[0050] In addition, in this embodiment, a vertical fixing rod 143 is provided inside the collection cylinder 142 placed inside the housing 140 along the axial direction of the collection cylinder 142. When the rolled-up chemically formed foil slides down, the outer roller 260 in the middle can be sleeved on the fixing rod 143, so that the chemically formed foil inside the collection cylinder 142 can be kept stably placed. Furthermore, a buffer layer is provided at the bottom of the collection cylinder 142 to prevent the chemically formed foil from colliding with the bottom wall of the collection cylinder 142 during the downward sliding process, thereby avoiding damage to the chemically formed foil product.

[0051] In this embodiment, three air ducts 124 are also provided on the inner sidewalls of both sides of the frame 120. One of the three air ducts 124 is located on the sidewall near the third rod 230 and above the rotating shaft; the other two are located on the sidewall near the first rod 210 and above and below the rotating shaft, respectively. The openings of the three air ducts 124 are all oriented towards the roller on the second rod 220, and are used to blow and clean the surface of the formed foil to remove dust, aluminum shavings, and other debris brought in during transportation. Furthermore, a buffer pad 125 is provided on the sidewall of the frame 120 near the first rod 210. The buffer pad 125 is vertically positioned below the rotating shaft to prevent the formed foil from colliding with the sidewall of the frame 120 during downward rotation, thus avoiding damage to the formed foil product. Meanwhile, a stop mechanism 128 is provided on the outer side wall of the frame 120 near the first rod 210 and above the first rod 210. The stop mechanism 128 has a baffle that can be raised and lowered. When the winding mechanism 200 finishes winding, the stop mechanism 128 can extend the baffle downward to restrict the position of the first insert 212 on the first rod 210, thereby limiting the orientation of the hinge shaft 216. This keeps the rotation direction of the second rod 220 in the same plane as the slide rail 122. Thus, after the connector 240 is separated from the third rod 230, the second rod 220 does not need to rotate axially anymore. The connector 240 can slide downward along the slide rail 122, which can prevent the second rod 220 from getting stuck during axial rotation and affecting the unloading of the foil.

[0052] like Figure 10 As shown, the second bearing 520 in the second mounting hole 127 of this embodiment has a second insertion hole 522 in the middle of its inner ring. The second insertion hole 522 is adapted to the cross-sectional shape of the third rod 230 with the fourth insertion block 232 and is used to insert the third rod 230, so that the third rod 230 can move axially and rotate relative to the frame 120. In this embodiment, the insertion hole of the bearing in the first mounting hole 121 and the insertion hole on the reducer rotation output end 132 are similar in shape and function to the second insertion hole 522, respectively adapting to the shape of the rod segment where the first insertion block 212 and the second insertion block 218 are located on the first rod 210.

[0053] Furthermore, in this embodiment, the upper surface of the front end of the housing 140 protrudes upward, and an auxiliary roller 300 is provided on the protruding upper surface. The auxiliary roller 300 is arranged parallel to the rotating shaft of the winding mechanism 200, and its height is lower than that of the winding mechanism 200. The auxiliary roller 300 is rotatably mounted on the mounting plate 310 on both sides, and the mounting plate 310 is connected to the upper surface of the front end of the housing 140. The auxiliary roller 300 includes an auxiliary rotating shaft and an auxiliary roller body. When the winding device is working, the chemically formed foil at the end of the production line is first guided by the auxiliary roller body before entering the winding mechanism 200 for winding. By setting the auxiliary roller 300, the tension of the chemically formed foil winding can be increased, making the wound chemically formed foil roll more stable.
