Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, specifically to a winding device for capacitor manufacturing. Background Technology

[0002] Two conductors close to each other, with a non-conductive insulating medium sandwiched in between, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor stores charge. During the production process, a winding device is needed to combine and wind the plastic film and metal foil used in capacitor production into the required capacitor core.

[0003] While existing winding devices can combine and wind two different types of plastic film and metal foil used in capacitor production, the lack of a corresponding compaction structure to press the combined plastic film and metal foil makes them prone to deformation or loosening during winding. This significantly reduces the tightness of subsequent windings. Furthermore, the unwinding structure in existing winding devices is cumbersome to assemble and disassemble, making it inconvenient for workers to easily disassemble and assemble the unwinding structure, resulting in poor practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] Example 1:

[0024] A winding device for capacitor production includes a support back plate 1, a first unwinding drum 3, a second unwinding drum 5, a drive shaft 6, a winding drum 7, a fixed base plate 8, and a servo motor 9. The fixed base plate 8 is fixedly installed on a designated position on a cement floor using external expansion bolts. The support back plate 1 is fixedly connected to the upper end face of the fixed base plate 8. The support back plate 1 is connected to the fixed base plate 8, the bottom support plate 27, the extension support plate 21, the support shaft 11, and the side support plate 42 by welding. The support back plate 1 can support the fixed base plate 8, the bottom support plate 27, the extension support plate 21, the support shaft 11, the side support plate 42, and the servo motor 9 respectively. The front end face of the support back plate 1 is symmetrically fixedly connected to the upper and lower sides of the support shaft 11. There are two sets of support shafts 11, and the two sets of support shafts 11 are of the same specification. The support shafts 11 are matched with the first unwinding drum 3 and the second unwinding drum 5 respectively. The two sets of support shafts 11 can support the first unwinding drum 3 and the second unwinding drum 5 respectively.

[0025] The support shaft 11 is fitted with a first unwinding drum 3 on its annular side. The first unwinding drum 3 is a rotatable structure and can wind up the external metal foil used in capacitor production. The first unwinding drum 3 is fitted with a second unwinding drum 5 directly below the first unwinding drum 3. The second unwinding drum 5 is a rotatable structure and can wind up the external plastic film used in capacitor production. A servo motor 9 is installed on the right side of the rear end face of the fixed base plate 8. The servo motor 9 is electrically connected to an external servo controller through wires. When the servo motor 9 is working, it can drive the transmission shaft 6 to rotate at a preset speed. The transmission shaft 6 is installed at the transmission end of the servo motor 9. The front end of the transmission shaft 6 is rectangular and can drive the winding drum 7 to rotate together.

[0026] A winding drum 7 is fitted onto the outer surface of the drive shaft 6. The winding drum 7 can wind up the external plastic film and external metal foil used in capacitor production after being compacted by the fastening component 2. A panel control cabinet 10 is set on the right side of the rear end face of the support back plate 1. The input end of the panel control cabinet 10 is connected to an external fixed power supply through wires. The output end of the panel control cabinet 10 is electrically connected to the first electric push rod 44 and the second electric push rod 23 through wires respectively. The panel control cabinet 10 allows the operator to control the extension and retraction of the first electric push rod 44 and the second electric push rod 23 according to the needs. Since the detailed internal structure and working principle of the panel control cabinet 10 are relatively mature technologies in the prior art, they will not be described in detail here. An anti-disengagement sleeve 61 is fitted onto the front side of the outer surface of the drive shaft 6. The anti-disengagement sleeve 61 matches the drive shaft 6 and can block and limit the winding drum 7 to prevent the winding drum 7 from loosening and slipping during rotation. An internal threaded through hole is opened in the middle of the upper end face of the anti-disengagement sleeve 61. Figure 3 As shown in the drawing), the internal thread of the through hole is fitted with a fixing screw. Figure 3(As shown in the drawing), the fixing screw and the internal threaded through hole can install and fix the anti-disengagement sleeve 61 on the outer surface of the drive shaft 6 for use.

[0027] The winding drum 7 has a strip groove 71 on its annular side. The strip groove 71 matches the ends of the compressed external plastic film and external metal foil used for capacitor production. The strip groove 71 makes it convenient for workers to clamp the ends of the external plastic film and external metal foil used for capacitor production onto the annular side of the winding drum 7 so that the subsequent rotating winding drum 7 can wind up the external plastic film and external metal foil used for capacitor production.

[0028] A clamping component 2 is provided between the first unwinding drum 3 and the second unwinding drum 5 and the winding drum 7. The clamping component 2 is used to compact the metal foil and plastic film wound by the winding drum 7, so as to prevent the external plastic film and external metal foil used in capacitor production from deforming or loosening during the winding process, thereby improving the subsequent winding tightness. The front end of the first unwinding drum 3 and the second unwinding drum 5 are both provided with a blocking component 4, and the blocking component 4 makes it convenient for the staff to easily disassemble and assemble the first unwinding drum 3 and the second unwinding drum 5 respectively.

[0029] The fastening assembly 2 includes an extension support plate 21, a second electric push rod 23, a pressure sensor 24, an upper support frame 25, a lower support frame 26, a bottom support plate 27, a support roller 28, and a pressure roller 29. The extension support plate 21 is fixedly connected to the upper side of the front end face of the support back plate 1, and the extension support plate 21 can support and fix the second electric push rod 23. The second electric push rod 23 is installed on the lower front face of the extension support plate 21. During operation, the second electric push rod 23 can drive the upper support frame 25 to rise and fall via the pressure sensor 24. The pressure sensor 24 is installed at the lower end of the second electric push rod 23. (Panel control cabinet 10) A pressure digital display 211 is installed on the lower side of the right end face. The pressure digital display 211 is connected to the pressure sensor 24 via a signal line. When the pressure sensor 24 is working, it will sense the downward pressure of the second electric push rod 23 and then transmit the pressure signal to the pressure digital display 211 in real time. The pressure digital display 211 will then display the pressure signal transmitted from the pressure sensor 24 in digital form for the operator to view. This will make it easier for the operator to adjust the downward pressure of the second electric push rod 23 to the required pressure and prevent the downward pressure of the pressing roller 29 from being too high or too low.

[0030] The lower end face of the pressure sensor 24 is connected to an upper support frame 25, which supports the pressure roller 29. The pressure roller 29 is installed inside the upper support frame 25. The pressure roller 29 has the same specifications as the support roller 28 and is rotatable. The front and rear widths of the pressure roller 29 are greater than the front and rear widths of the external plastic film and external metal foil used in capacitor production, respectively. The rotatable pressure roller 29 can press down on the passing external plastic film and external metal foil used in capacitor production. A bottom support plate 27 is fixedly connected to the lower side of the front end face of the support back plate 1. The bottom support plate 27 supports the lower support frame 26. The lower support frame 26 is installed on the upper end face of the bottom support plate 27 and supports the support roller 28. A support roller 28 is installed on the inner side of the 6. The front and rear widths of the pressure roller 29 are greater than the front and rear widths of the external plastic film and external metal foil used for capacitor production, respectively. The support roller 28 is a rotatable structure, which can support and guide the external plastic film and external metal foil used for capacitor production. A second limiting rod 22 is provided on the rear side of the upper end face of the upper support frame 25. The second limiting rod 22 is connected to the upper support frame 25 by welding. The second limiting rod 22 can limit the upper support frame 25 and prevent the upper support frame 25 from shaking or shifting during lifting and lowering. A reinforcing inclined plate 271 is fixedly connected to the lower end face of the bottom support plate 27. The reinforcing inclined plate 271 can further improve the support stability of the bottom support plate 27.

[0031] Example 2:

[0032] Based on Embodiment 1, in this embodiment, by controlling the retraction of the first electric push rod 44, the first electric push rod 44 can drive the two sets of limit bars 41 to move to the left side together through the connecting plate 45, so that they are separated from the blocking ring 46 and the support shaft 11. Then, the blocking rings 46 on the upper and lower sides can be pulled and disassembled respectively. Then, the first unwinding drum 3 and the second unwinding drum 5 can be pulled and disassembled for replacement, which is convenient for disassembly and assembly.

[0033] The blocking assembly 4 includes a limiting strip 41, a side support plate 42, a first electric push rod 44, a connecting plate 45, and a blocking ring 46. The side support plate 42 is fixedly connected to the left side of the front end face of the support back plate 1. The side support plate 42 can support the first electric push rod 44. The first electric push rod 44 is installed inside the front side of the side support plate 42. When working, the first electric push rod 44 can drive the connecting plate 45 to move left and right. The right end of the first electric push rod 44 is connected to the connecting plate 45. The connecting plate 45 is welded to the limiting strip 41 and the first limiting rod 43. The connecting plate 45 supports two sets of limiting bars 41. The right end face of the connecting plate 45 is symmetrically provided with limiting bars 41 on both the upper and lower sides. There are two sets of limiting bars 41, and the two sets of limiting bars 41 are the same size. When the limiting bars 41 move to the right, their rear ends are in contact with the front ends of the support shaft 11 and the blocking ring 46. The two sets of limiting bars 41 can simultaneously block and limit the two sets of support shafts 11 and blocking rings 46, so as to prevent the first unwinding drum 3 and the second unwinding drum 5 from loosening or shifting during use.

[0034] A blocking ring 46 is fitted on the front side of the annular side of the support shaft 11. The blocking ring 46 matches the support shaft 11. Two sets of blocking rings 46 are fitted, and the two sets of blocking rings 46 are of the same specification. The two sets of blocking rings 46 can respectively block and limit the first unwinding drum 3 and the second unwinding drum 5. A first limiting rod 43 is provided on the upper side of the left end face of the connecting plate 45. The first limiting rod 43 will follow the left and right movement of the connecting plate 45 and limit it to prevent the connecting plate 45 from shaking or deviating during left and right movement. A limiting baffle 47 is provided on the left end of the first limiting rod 43. The limiting baffle 47 is connected to the first limiting rod 43 by welding. The limiting baffle 47 can limit the rightward movement range of the first limiting rod 43. To prevent the connecting plate 45 from causing the limiting stop strip 41 to move excessively to the right, a limiting block 48 is provided on the upper side of the inner annular side of the blocking ring 46. The limiting block 48 is connected to the blocking ring 46 by welding. A limiting groove 49 is opened on the front side of the annular side of the support shaft 11, and the limiting groove 49 matches the limiting block 48. The matching limiting groove 49 and the limiting block 48 can limit the blocking ring 46, so that when the blocking ring 46 is fitted into the front end of the support shaft 11, its rear end face is exactly in contact with the front end face of the first unwinding drum 3 and the second unwinding drum 5. This prevents the blocking ring 46 fitted on the support shaft 11 from being overly in contact with the first unwinding drum 3 and the second unwinding drum 5, which would increase the rotational resistance of the first unwinding drum 3 and the second unwinding drum 5.

[0035] Working principle: In the capacitor manufacturing process, this device is used to combine and wind the outer plastic film sheet wound on the annular side of the first unwinding drum 3 and the outer metal foil sheet wound on the annular side of the second unwinding drum 5 into the required capacitor core. (Refer to...) Figure 1The operator first controls the extension of the second electric push rod 23, so that the second electric push rod 23 drives the pressing roller 29 to move down through the pressure sensor 24 and the upper support frame 25 to press the superimposed external plastic film and external metal foil. During this process, the pressure digital display 211 will display the pressing pressure value of the second electric push rod 23 transmitted by the pressure sensor 24 in real time, so that the operator can adjust the pressing pressure of the second electric push rod 23 to the required pressure and avoid the pressing roller 29 from being too large or too small.

[0036] Once the downward pressure of the second electric push rod 23 is adjusted to the required pressure, the servo motor 9 can be started. The servo motor 9, through the drive shaft 6, drives the winding drum 7 to wind the superimposed external plastic film and external metal foil (the rotation direction of the winding drum 7 is...). Figure 1 (As shown in the drawing), during this process, the superimposed and combined outer plastic film and outer metal foil will be compacted by the support roller 28 and the pressure roller 29 to prevent the outer plastic film and outer metal foil from deforming or loosening during the winding process of the winding drum 7, thereby improving the winding tightness of the winding drum 7. At the same time, the limiting strip 41 will block and limit the first unwinding drum 3 and the second unwinding drum 5 through the blocking ring 46, and the rear end face of the first unwinding drum 3 and the second unwinding drum 5 will be in contact with the front end face of the support back plate 1, thereby preventing the first unwinding drum 3 and the second unwinding drum 5 from shifting or loosening during the unwinding process of the outer plastic film and outer metal foil;

[0037] During later use, when it is necessary to replace the first unwinding drum 3 and the second unwinding drum 5, the operator first controls the first electric push rod 44 to retract, so that the first electric push rod 44 drives the two sets of limit stops 41 to move to the left position together through the connecting plate 45. Then, the upper and lower blocking rings 46 are pulled and removed respectively. At this time, the first unwinding drum 3 and the second unwinding drum 5 can be pulled and removed for replacement (see reference). Figure 3 Conversely, it allows for the installation and use of new unwinding drums 3 and 5, which are wound with external plastic film and external metal foil. This enables workers to easily assemble and disassemble the first unwinding drum 3 and the second unwinding drum 5. After loosening the fixing screws, the anti-disengagement sleeve 61 can be removed from the drive shaft 6, at which point the winding drum 7, which is wound with the superimposed external plastic film and external metal foil, can be taken away.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
