Description

Technical Field

[0001] The invention relates to the technical field of capacitor manufacturing, in particular to a feeding parallel brush foil mechanism. Background Art

[0002] A capacitor is a device that holds an electric charge and is one of the most widely used electronic components in electronic devices. It is widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. A capacitor consists of a core, a casing, and a rubber cover. The core is made by winding electrolytic paper with positive and negative foils. During the capacitor manufacturing process, the foil conveying process can easily cause scratches on the foil, leading to damage to the oxide film. Furthermore, impurities such as burrs and dust are generated during the manufacturing and cutting of the positive and negative foils. These burrs or dust remaining in the positive and negative foils can easily cause the capacitor to short-circuit and fail, resulting in high leakage current. Summary of the Invention

[0003] Based on this, it is necessary to provide a feeding parallel foil brushing mechanism to solve the problem in the prior art that the aluminum foil inside the capacitor fails due to short circuit due to scratches or residual burrs and dust.

[0004] The present invention solves the technical problem by adopting the following technical solutions:

[0005] A feeding parallel foil brushing mechanism comprises: a substrate and a foil strip, a fixing frame is provided on one side of the substrate, a wheel group is provided on the side of the fixing frame away from the substrate, the wheel group comprises a first track roller, a second track roller, a first rotating wheel and a second rotating wheel installed at intervals on the fixing frame; a feeding turntable is rotatably provided on one side of the first track roller, the feeding turntable outputs the foil strip which is wound around the first track roller, the first rotating wheel, the second rotating wheel and the second track roller; a detection mechanism for detecting whether the foil strip is being conveyed is provided above the feeding turntable; a dust removal mechanism for removing dust from the foil strip is provided on one side of the second track roller; a nailing mechanism is provided on the side docking with the dust removal mechanism.

[0006] With this technical solution, during loading, the upper foil strip is installed on the feed turntable, and the end of the foil strip is wound through the wheel set. The wheel set guides the foil strip, keeping its trajectory horizontal, preventing it from deviating from its trajectory and causing scratches. After passing through the wheel set, the foil strip passes through a dust removal mechanism. The brushes in the dust removal mechanism remove dust and burrs from both sides of the foil strip, keeping the foil surface clean. This pre-cleaning and dust removal process ensures that the finished element is clean and dust-free, simplifying the process and improving product quality.

[0007] Preferably, the fixing frame includes a slide rail, the slide rail is connected to a fixing seat, and the fixing seat is fixedly connected to the base plate, so that the fixing frame can move away from or approach the base plate in the sliding direction of the slide rail.

[0008] By adopting the above technical solution, the fixing frame is located on the side of the base plate. Through the connection and fixation of the slide rail, the fixing frame can slide along the slide rail to make the fixing frame move away from or close to the base plate. At the same time, the wheels on the fixing frame move with the fixing frame to achieve the effect of calibration and positioning.

[0009] Preferably, the fixing frame also includes an adjustment mechanism for adjusting the distance between the fixing frame and the substrate, and the adjustment mechanism includes a screw rod and an elastic member, the screw rod is sleeved in the elastic member, one end of the screw rod passes through the fixing frame, and the end of the screw rod away from the fixing frame is threadedly connected to the fixing seat.

[0010] By adopting the above technical solution, the adjustment mechanism provided on the fixing frame enables the sliding distance between the fixing frame and the base plate to be adjusted and controlled by the adjustment mechanism. The stroke of the screw in the adjustment mechanism enables the fixing frame to drive the wheel group closer to or away from the base plate. The screw is sleeved in the elastic member to provide elastic force, so that the fixing frame is easy to slide and reset on the slide rail, thereby achieving the effect of precise adjustment.

[0011] Preferably, the wheel assembly further comprises a third rotating wheel and a fourth rotating wheel for winding the foil strip, wherein the third rotating wheel is located below the first rotating wheel, and the fourth rotating wheel is located below the second rotating wheel.

[0012] By adopting the above technical solution, a third and fourth revolver are respectively positioned below the first and second revolvers. The third and fourth revolvers wind the foil, acting as both a position limiter and a conveyor. Furthermore, the third and fourth revolvers can vertically move away from or toward the first and second revolvers. If the foil wrapped around the revolver assembly is too loose, the third and fourth revolvers are controlled to move away from the first and second revolvers, increasing the pulling force and tightening the foil, thereby preventing the produced elements from becoming too loose during the winding process. If the foil wrapped around the revolver assembly is too tight, the third and fourth revolvers are controlled to move toward the first and second revolvers, reducing the pulling force and loosening the foil, thereby preventing it from breaking.

[0013] Preferably, the third rotating wheel and the fourth rotating wheel are arranged at one end of a fixed rod, and the fixed rod is used to drive the third rotating wheel and the fourth rotating wheel to intermittently rise or fall in the vertical direction.

[0014] By adopting the above technical solution, the fixed rod drives the third and fourth rotating wheels to intermittently rise or fall in the vertical direction, so that the third and fourth rotating wheels are close to or away from the first and second rotating wheels in the vertical direction, thereby adjusting the tightness of the foil.

[0015] Preferably, the dust removal mechanism includes two groups of brushes and dust suction components that are arranged opposite to each other, the foil strip passes through the dust removal mechanism, and the brushes abut against both sides of the foil strip.

[0016] By adopting the above technical solution, the dust removal mechanism plays a role in dust removal, the foil strip is strung together and abuts against the brush in the dust removal mechanism, the brush removes dust from the periphery of the foil strip, and the dust suction component sucks out the removed dust or burrs, thereby enhancing the cleaning effect.

[0017] Preferably, the outer periphery of the first track roller and the second track roller are respectively provided with grooves for accommodating the foil strip, and the grooves in the first track roller and the second track roller are aligned on the same straight line.

[0018] By adopting the above technical solution, grooves for accommodating the foil are respectively provided on the outer periphery of the first track roller and the second track roller. The foil is wound and accommodated in the grooves, and the foil is limited so that the foil always remains on a preset horizontal straight line during the transportation process, thereby avoiding scratching the foil.

[0019] Preferably, the axes of the first track roller, the second track roller, the first rotating wheel and the second rotating wheel are parallel to each other and on the same horizontal plane, and are perpendicular to the side surface of the fixing frame.

[0020] By adopting the above technical solution, the axes of the first track roller, the second track roller, the first rotating wheel and the second rotating wheel are all parallel to the same horizontal plane, so that the foil strip is also kept on the same horizontal plane during transportation.

[0021] The advantages and positive effects of the present invention are:

[0022] The present invention provides a parallel foil feeding mechanism to address the prior art problem of short-circuiting and failure of the aluminum foil inside capacitors due to scratches or residual burrs and dust. Compared with the prior art, the present invention has the following advantages:

[0023] The present invention arranges a wheel assembly for conveying foil strips mounted parallel to the same fixed frame. Through a single adjustment of the adjustment mechanism, the first track roller, the second track roller, the first rotating wheel, the second rotating wheel, and the feed turntable in the wheel assembly can be synchronously moved to form a straight line. This ensures that the foil strips released from the feed turntable remain in a straight line on the wheel assembly, preventing scratches on the foil strip edges, facilitating commissioning, and saving adjustment time. Furthermore, a dust removal mechanism is provided to remove dust from the foil strips, removing burrs and dust remaining on the foil strips. This results in a clean foil strip when the foil strips are wound, thus resolving the problem of short-circuit failure of the aluminum foil inside capacitors due to scratches or residual burrs and dust.

[0036] like Figures 1 to 7 As shown, a feeding parallel foil brushing mechanism includes: a substrate 1, a foil strip 10, a fixing frame 4 is provided on one side of the substrate 1, and a wheel group 6 is provided on the side of the fixing frame 4 away from the substrate 1, and the wheel group 6 includes a first track roller 601, a second track roller 602, a first rotating wheel 603, and a second rotating wheel 604 installed at intervals on the fixing frame 4; a feeding turntable 2 is rotatably provided on one side of the first track roller 601, and the feeding turntable 2 outputs the foil strip 10 which is wound around the first track roller 601, the first rotating wheel 603, the second rotating wheel 604, and the second track roller 602; a detection mechanism 3 for detecting whether the foil strip 10 is conveyed is provided above the feeding turntable 2; a dust removal mechanism 8 for removing dust from the foil strip 10 is provided on one side of the second track roller 602; and a nailing mechanism 9 is provided on the side docking with the dust removal mechanism 8.

[0037] During operation, when loading, the upper foil strip 10 is installed in the feeding turntable 2, and the end of the foil strip 10 is wound and passed through the wheel set 6. The foil strip 10 is guided by the wheel set 6 so that the travel trajectory of the foil strip 10 remains on the same horizontal line, which plays a role in preventing the foil strip 10 from deviating from the trajectory and being scratched. After passing through the wheel set 6, the foil strip 10 is passed through the dust removal mechanism 8. The brush 801 in the dust removal mechanism 8 cleans dust and burrs on both sides of the foil strip 10, keeping the surface of the foil strip 10 clean. This pre-cleaning and dust removal is carried out for the stapling and winding process of the foil strip 10, ensuring that the element obtained after winding is clean and dust-free, simplifying the process and improving product quality.

[0038] In some embodiments, reference Figure 1 、 Figure 3 A fixed frame 4 is provided on one side of the substrate 1. A wheel assembly 6 is provided on the side of the fixed frame 4 facing away from the substrate 1. The wheel assembly 6 includes a first track roller 601, a second track roller 602, a first rotating wheel 603, and a second rotating wheel 604, which are installed at intervals on the fixed frame 4. The outer peripheries of the first track roller 601 and the second track roller 602 are respectively provided with grooves 600 for accommodating the foil 10. The grooves 600 in the first track roller 601 and the second track roller 602 are aligned on the same straight line. The axes of the first track roller 601, the second track roller 602, the first rotating wheel 603, and the second rotating wheel 604 are all parallel and on the same horizontal plane and perpendicular to the side of the fixed frame 4. Specifically, the side of the substrate 1 facing away from the fixed frame 4 can be installed in other processing equipment, such as a coiling machine or winding machine for processing capacitor elements. A fixing frame 4 is provided on one side of the substrate 1. The fixing frame 4 primarily serves to secure and position the wheel assembly 6. Wheel assembly 6 is provided on the side of the fixing frame 4 facing away from the substrate 1. A first rotating wheel 603 and a second rotating wheel 604 are spaced apart between a first track roller 601 and a second track roller 602. The axes of the first track roller 601, the second track roller 602, the first rotating wheel 603, and the second rotating wheel 604 in the wheel assembly 6 are aligned horizontally, ensuring that the foil 10 remains aligned horizontally when wound around the first track roller 601, the second track roller 602, the first rotating wheel 603, and the second rotating wheel 604. Grooves 600 are provided on the outer periphery of the first track roller 601 and the second track roller 602 for accommodating the foil 10. The foil 10 is wound and accommodated in these grooves, limiting its position and ensuring that it remains aligned horizontally during transport, thus preventing scratches on the foil 10.

[0039] In some embodiments, reference Figure 1 、 Figure 3The fixing frame 4 includes a slide rail 401, the slide rail 401 is connected to the fixing seat 5, and the fixing seat 5 is fixedly connected to the substrate 1, so that the fixing frame 4 can move away from or approach the substrate 1 in the sliding direction of the slide rail 401.

[0040] The fixing frame 4 also includes an adjustment mechanism 402 for adjusting the distance between the fixing frame 4 and the substrate 1. The adjustment mechanism 402 includes a screw rod 4021 and an elastic member 4022. The screw rod 4021 is sleeved in the elastic member 4022. One end of the screw rod 4021 passes through the fixing frame 4. The end of the screw rod 4021 away from the fixing frame 4 is threadedly connected to the fixing seat 5.

[0041] Specifically, the fixed frame 4 is connected to the fixed seat 5 via a slide rail 401, and the fixed frame 4 can slide on the fixed seat 5 via the slide rail 401. The fixed seat 5 is fixedly connected to the substrate 1, so that the fixed seat 5 can drive the wheel set 6 to move closer to or away from the substrate 1 under the limiting and guiding action of the slide rail 401. The sliding distance between the fixed frame 4 and the substrate 1 can be adjusted and controlled by the adjustment mechanism 402. The stroke of the screw rod 4021 in the adjustment mechanism 402 allows the fixed frame 4 to drive the wheel set 6 closer to or away from the substrate 1. The screw rod 4021 is sleeved in the elastic member 4022, providing elastic force, making it easier for the fixed frame 4 to slide and reset on the slide rail 401, achieving a precise adjustment effect. By adjusting the position of the fixed frame 4, the first track roller 601, the second track roller 602, the first rotating wheel 603, and the second rotating wheel 604 in the wheel set 6 are aligned and in the same straight line with the transmission direction of the foil strip 10, preventing the foil strip 10 from skewing and scratching.

[0042] In some embodiments, reference Figure 1 、 Figure 6 A feed turntable 2 is rotatably provided on one side of the first track roller 601. The feed turntable 2 outputs the foil tape 10 and winds it through the first track roller 601, the first rotating wheel 603, the second rotating wheel 604, and the second track roller 602. Specifically, the feed turntable 2 is used to mount the foil tape 10 to be output. After the end of the foil tape 10 is output from the feed turntable 2, it is wound sequentially around the first track roller 601, the first rotating wheel 603, the third rotating wheel 605, the second rotating wheel 604, the fourth rotating wheel 606, and the second track roller 602. The first track roller 601, the first rotating wheel 603, the third rotating wheel 605, the second rotating wheel 604, the fourth rotating wheel 606, and the second track roller 602 can all rotate around their own axes.

[0043] In some embodiments, reference Figure 1 、 Figure 2The wheel assembly 6 further includes a third rotating wheel 605 and a fourth rotating wheel 606 for winding the foil strip 10. The third rotating wheel 605 is located below the first rotating wheel 603, and the fourth rotating wheel 606 is located below the second rotating wheel 604. The third rotating wheel 605 and the fourth rotating wheel 606 are arranged at one end of a fixed rod 7, and the fixed rod 7 is used to drive the third rotating wheel 605 and the fourth rotating wheel 606 to intermittently rise or fall in the vertical direction.

[0044] Specifically, a third rotating wheel 605 and a fourth rotating wheel 606 are provided below the first rotating wheel 603 and the second rotating wheel 604, respectively. The third rotating wheel 605 and the fourth rotating wheel 606 are used to wind the foil 10, on the one hand, to limit and convey the foil 10. On the other hand, driven by the fixed rod 7, the third rotating wheel 605 and the fourth rotating wheel 606 can move vertically away from or closer to the first rotating wheel 603 and the second rotating wheel 604. When the foil 10 wound in the wheel assembly 6 is too loose, the fixed rod 7 is controlled to drive the third rotating wheel 605 and the fourth rotating wheel 606 away from the first rotating wheel 603 and the second rotating wheel, thereby increasing the pulling force and tightening the foil 10, thereby preventing the elements produced during the winding process from being too loose. When the foil 10 wound in the wheel assembly 6 is too tight, the third rotating wheel 605 and the fourth rotating wheel 606 are controlled to move closer to the first rotating wheel 603 and the second rotating wheel, thereby reducing the pulling force and loosening the foil 10, thereby preventing the foil 10 from breaking.

[0045] In some embodiments, reference Figure 1 A detection mechanism 3 is provided above the feed turntable 2 for detecting the presence of the foil tape 10 being fed. Specifically, the foil tape 10 outputted from the feed turntable 2 passes under the detection mechanism 3. Once the outputted foil tape 10 is within the detection range of the detection mechanism 3, the detection mechanism 3 can sense the presence of the foil tape 10. When the detection mechanism 3 senses that no foil tape 10 is passing below, the detection mechanism 3 transmits the collected signal to the controller, determining that no foil tape 10 is output. At this time, the controller issues a stop command, causing the control mechanism to stop operating and resume operation after a new foil tape 10 is added, thus providing a material shortage alarm.

[0046] In some embodiments, reference Figure 1 Figure 2 、 Figure 7A dust removal mechanism 8 is provided on one side of the second track roller 602 for removing dust from the foil 10; a stapling mechanism 9 is provided on the side that interfaces with the dust removal mechanism 8. Specifically, the dust removal mechanism 8 includes two sets of opposing brushes 801 and a dust collection assembly 802. The foil 10 passes through the dust removal mechanism 8, with the brushes 801 abutting against both sides of the foil 10. After the foil 10 passes through the first track roller 601, the first rotating wheel 603, the third rotating wheel 605, the second rotating wheel 604, the fourth rotating wheel 606, and the second track roller 602, it passes through the dust removal mechanism 8. The two sets of opposing brushes 801 abut against the outer periphery of the foil 10, removing burrs and dust from the outer periphery of the foil 10. The dust collection assembly 802 absorbs air to absorb fallen burrs and dust, further cleaning the surface of the foil 10 and reducing subsequent short circuits caused by burrs and dust. The brushes 801 in the dust removal mechanism 8 can be opened or closed along the fulcrum. After the foil strip 10 is loaded, the brushes 801 on both sides automatically close. The closing stroke of the brushes 801 is adjustable and can be quickly disassembled and replaced. The brushes 801 can be anti-static soft brushes. After the foil strip 10 is loaded, the anti-static brushes are used to clean the burrs or dust on the surface of the foil strip 10 before the stapling and winding process. This prevents scratches on the edges of the foil strip, makes adjustment simple, and simplifies the process. It is convenient for debugging and saves adjustment time. On the other hand, by providing the dust removal mechanism 8 to remove dust from the foil strip, the burrs and dust remaining on the foil strip 10 are removed, and a clean foil strip is obtained when the foil strip is wound, which solves the problem of short-circuit failure of the aluminum foil inside the capacitor due to scratches or residual burrs and dust.

[0047] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
