Description

Technical Field

[0001] This invention relates to the technical field of copper foil production machine accessories, and in particular to a multi-axis synchronous control winding device for an ultra-thin copper foil production machine. Background Technology

[0002] With the promotion of new energy in recent years, the copper foil used in power lithium batteries is becoming thinner, and there are specific requirements for the length of a single roll of foil, requiring no joints and no wrinkles. This puts a deeper test on the stability and synchronization of copper foil production equipment.

[0003] As the final stage of copper foil production equipment, the winding mechanism of a copper foil production machine plays a crucial role in the entire copper foil production process. Firstly, copper foil production is a continuous process, and the winding process requires high tension control, necessitating high precision and reliability from the winding mechanism. Secondly, when the copper foil reaches a certain diameter on the winding roller, a new winding roller must be replaced. Replacing the winding roller requires removing the old one and installing the new one, which takes time. Since the copper foil production machine continuously produces copper foil, to avoid the accumulation and wrinkling of the copper foil, it is necessary to shorten the replacement time of the winding roller or achieve multi-axis synchronous operation for the removal and installation of the winding roller. Therefore, it is essential to invent a multi-axis synchronous control winding device for ultra-thin copper foil production machines to solve the above problems. Summary of the Invention

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention provides a support assembly, above which are a positioning assembly, a tensioning assembly, and a take-up roller clamping assembly. The positioning assembly positions and pulls the copper foil to ensure it is wound into the middle of the take-up roller. The tensioning assembly adjusts the tension of the copper foil during winding to ensure effective winding. The take-up roller clamping assembly clamps, fixes, and drives the take-up roller, thus enabling the winding of the copper foil. Multiple take-up rollers can be pre-installed on the clamping assembly to allow for synchronized control of roller removal and installation.

[0017] 2. The present invention provides a take-up roller support assembly, which includes a support base. The support base can support multiple take-up rollers. When disassembling the take-up rollers after they have been wound up, the position of multiple take-up rollers can be adjusted simultaneously by rotating the support base so that the take-up rollers that have not wound up the copper foil can be connected to the winding path of the copper foil. This allows for the installation of the intermediate shaft of multiple take-up rollers.

[0018] 3. This invention, through the cooperation of the clamping component, the extrusion component, etc., achieves the following: First, the clamping component can adapt to winding rollers of different diameters. Second, during the switching of winding rollers, even if the transmission connection between the winding roller and the drive component is disconnected, the winding roller can still continue winding, thus preventing wrinkles from forming on the copper foil being discharged from the foil-making machine due to the disconnection of the transmission connection between the winding roller and the drive component. Third, even if the drive component malfunctions, the copper foil can still be wound, thus preventing the foil-making machine from stopping and resulting in low production efficiency. Fourth, when cutting copper foil and changing winding rollers, the invention avoids the need for machine downtime for replacement as in existing technologies, thereby improving production efficiency; it also avoids the alignment and correction process after cutting.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 16As shown, this invention provides a multi-axis synchronous control winding device for an ultra-thin copper foil production machine, including a support assembly 1. Above the support assembly 1, from left to right, are arranged a plurality of positioning components 2, a single tensioning component 3, and a single winding roller support assembly 4. The winding roller support assembly 4 includes a U-shaped support base 401. Specifically, the U-shaped support base 401 is fixedly connected to the upper surface of the support assembly 1 by bolts. Two inclined support arms 402, symmetrically distributed front to back and slidably connected to the top of the U-shaped support base 401, are provided. Specifically, two T-shaped grooves, symmetrically distributed front to back, are provided on the upper surface of the U-shaped support base 401. A T-shaped slide is provided inside the T-shaped groove. The upper surface of the T-shaped slide is fixed at the center. An inclined support arm 402 is fixedly connected; an annular connecting seat 403 is fixedly connected to the top of the inner side of the inclined support arm 402; a support seat 404 is movably connected to the middle of the inner side of the annular connecting seat 403; two support seats 404 are connected to each other by a width adjustment component 5; the middle of the outer side of the support seat 404 is connected to the annular connecting seat 403 by a locking component 6; a plurality of support plates 405 arranged in an annular array are fixedly connected to the peripheral sidewall of each support seat 404; a rotating shaft 406 is rotatably connected to the middle of each support plate 405 by a bearing; a transmission gear 407 driven by a drive component 8 is fixedly connected to one end of each rotating shaft 406; a fixed plate 408 is provided in the middle of the other end of the rotating shaft 406; and a clamping component 9 is rotatably connected to the other end of the rotating shaft 406.

[0038] The clamping assembly 9 includes a turntable 901. Four arc-shaped clamping plates 902 are arranged in a circular array on the turntable 901 and are slidably connected to it. Specifically, four limiting grooves are arranged in a circular array on the turntable 901. Limiting sliders are connected to the inner walls of the limiting grooves via return springs. The limiting sliders are slidably connected to the turntable 901 and fixedly connected to the arc-shaped clamping plates 902. A limiting slide is provided on the outer wall of the arc-shaped clamping plate 902. A collar 903 is slidably sleeved on the outer side of the rotating shaft 406. A spring is provided between the collar 903 and the fixed plate 408. Two concentric rings 904 of different diameters are rotatably connected to the side of the fixed plate 408 away from the transmission gear 407. The rings 904 are movably connected to the fixed plate 408 via electromagnetic pins and holes. Specifically, electromagnetic pins are provided at positions opposite to the two rings 904 within the fixed plate 408. The pin and the ring 904 are provided with insertion holes arranged in a circumferential array and locked with the electromagnetic pin; one of the rings 904 is provided with pressing components 7 that cooperate with the limiting slide rail symmetrically on the top and bottom, and the other ring 904 is provided with pressing components 7 that cooperate with the limiting slide rail symmetrically on the left and right. The collar 903 is provided with limiting ears symmetrically, and the limiting ears cooperate with the pressing components 7 on the larger diameter ring 904. The pressing components 7 can extend and retract radially and axially along the rotating shaft 406. The circumferential sidewall of the collar 903 is provided with two axial reciprocating track grooves 10 at different heights that cooperate with the pressing components 7 on the smaller diameter ring 904. The top axial reciprocating track groove 10 is obtained by moving the bottom axial reciprocating track groove 10 upward and then rotating it in the circumferential direction to make the two axial reciprocating track grooves 10 misaligned in the circumferential direction. During operation, the arc-shaped clamping plate 902 is squeezed by the extrusion assembly 7. The arc-shaped clamping plate 902 moves towards the center of the turntable 901 and clamps the take-up roller. The locking and unlocking of the fixed plate 408 and the ring 904 are realized by controlling the extension and retraction of the electromagnetic pin.

[0039] The extrusion assembly 7 includes a first electric telescopic rod 701 connected to the ring 904. A second electric telescopic rod 702 is vertically fixed to the end of the first electric telescopic rod 701 away from the ring 904. The second electric telescopic rod 702 cooperates with the limiting slide. The axial reciprocating track groove 10 includes a clockwise half-turn spiral groove and a counterclockwise half-turn spiral groove. The first ends of the clockwise half-turn spiral groove and the counterclockwise half-turn spiral groove are connected, and the tail ends of the clockwise half-turn spiral groove and the counterclockwise half-turn spiral groove are connected.

[0040] When the control collar 903 rotates, the second electric telescopic rod 702 of one of the extrusion components 7 on the smaller diameter ring 904 retracts, while the first electric telescopic rod 701 of the same extrusion component 7 retracts to a position engaging with one of the axial reciprocating grooves 10. Simultaneously, the second electric telescopic rod 702 of the other extrusion component 7 on the smaller diameter ring 904 retracts, while the first electric telescopic rod 701 of the other extrusion component 7 retracts to a position engaging with another axial reciprocating groove 10. Then, the second electric telescopic rod 702 of one extrusion component 7 extends, inserting its end into one of the axial reciprocating grooves 10, while the second electric telescopic rod 702 of the other extrusion component 7 extends, inserting its end into another axial reciprocating groove 10; that is, as... Figure 16 The starting position is shown.

[0041] Then, one of the first electric telescopic rods 701 on the smaller diameter ring 904 is controlled to retract. Under the action of one of the axial reciprocating track grooves 10, the collar 903 rotates clockwise. Since the end of the second electric telescopic rod 702 of the other extrusion component 7 is located at the highest point of the axial reciprocating track groove 10, and the end of the second electric telescopic rod 702 of the other extrusion component 7 is not located at the lowest point of the other axial reciprocating track groove 10, under the action of the retraction of the first electric telescopic rod 701 of the other extrusion component 7 and the action of one of the axial reciprocating track grooves 10, the end of the second electric telescopic rod 702 of the other extrusion component 7 smoothly enters the groove at point A from the starting point, that is, smoothly enters the counterclockwise half-turn spiral groove from the clockwise half-turn spiral groove. Then, the first electric telescopic rod 701 of the other extrusion component 7 that has entered the counterclockwise half-turn spiral groove is controlled to retract. The retraction of the first electric telescopic rod 701 causes the collar 903 to continue to rotate clockwise.

[0042] When the first electric telescopic rod 701 of one of the extrusion components 7 retracts to the point where the end of the corresponding second electric telescopic rod 702 of the extrusion component 7 is at the lowest point of the axial reciprocating track groove 10, i.e., point D, since the end of the second electric telescopic rod 702 of the other extrusion component 7 is not at the lowest point of one of the axial reciprocating track grooves 10, i.e., it is at point A, under the action of the retraction of the first electric telescopic rod 701 of the other extrusion component 7 and the action of the other axial reciprocating track groove 10, the end of the second electric telescopic rod 702 of one of the extrusion components 7 enters the groove at point E from point D, i.e., smoothly enters the clockwise half-turn spiral groove from the counterclockwise half-turn spiral groove. Then, the first electric telescopic rod 701 of one of the extrusion components 7 that has entered the clockwise half-turn spiral groove is controlled to extend. As the first electric telescopic rod 701 of one of the extrusion components 7 extends and the first electric telescopic rod 701 of the other extrusion component 7 retracts, the collar 903 continues to rotate clockwise.

[0043] When the end of the second electric telescopic rod 702 of another extrusion assembly 7 moves to the lowest point of another axial reciprocating track groove 10, i.e., point B, since the end of the second electric telescopic rod 702 of one of the extrusion assemblies 7 is located at point E, under the extension action of the first electric telescopic rod 701 of one of the extrusion assemblies 7 and the action of one of the axial reciprocating track grooves 10, the end of the second electric telescopic rod 702 of the other extrusion assembly 7 enters the groove at point C from point B, i.e., smoothly enters the clockwise half-turn spiral groove from the counterclockwise half-turn spiral groove. Then, the extension of the second electric telescopic rod 702 of the other extrusion assembly 7 is controlled. Under the extension action of the second electric telescopic rod 702 of the other extrusion assembly 7 and the extension action of the first electric telescopic rod 701 of one of the extrusion assemblies 7, the collar 903 continues to rotate clockwise.

[0044] When the end of the second electric telescopic rod 702 of one of the extrusion components 7 moves to the top of one of the axial reciprocating track grooves 10, i.e., point F, since the end of the second electric telescopic rod 702 of the other extrusion component 7 is located at point C, under the extension of the first electric telescopic rod 701 of the other extrusion component 7 and the action of the other axial reciprocating track groove 10, the end of the second electric telescopic rod 702 of one of the extrusion components 7 enters the groove where the starting point is located from point F, that is, smoothly enters the counterclockwise half-turn spiral groove from the clockwise half-turn spiral groove. Then, the second electric telescopic rod 702 of one of the extrusion components 7 is controlled to retract. Under the extension of the second electric telescopic rod 702 of the other extrusion component 7 and the retraction of the second electric telescopic rod 702 of one of the extrusion components 7, the ends of the second electric telescopic rods 702 of both extrusion components 7 finally move to the starting position of the axial reciprocating track groove 10, thereby realizing the rotation of the collar 903 one revolution. Repeating the above actions, the collar 903 performs circular motion. It should be noted that point C is the midpoint of the clockwise half-turn spiral groove, not the turning point of the low or high point.

[0045] The support assembly 1 includes a support frame 101, with inclined support frames 102 fixedly connected to both ends of the support frame 101, and a support leg fixedly connected to the bottom end of the inclined support frame 102; a fixed roller 103 is connected to the top of the outer side of an inclined support frame 102 via an inclined support arm.

The upper surface of the portal movable seat 308 is movably connected to the lower surface of the positioning plate 307 through a tension spring. A tension roller is movably connected to the bottom end of the inner side wall of the portal movable seat 308 through a bearing. Sliding blocks 309 are fixedly connected to both ends of the outer side of the portal movable seat 308, which slide and cooperate with the tension base 301. Specifically, a strip groove is opened through the middle of the tension base 301, and the sliding block 309 passes through and slides through the strip groove. When the spring is difficult to adapt to the tension of the copper foil, the cylinder 303 is controlled to extend and retract to adapt to the tension of the copper foil.

[0049] The locking assembly 6 includes multiple positioning grooves 605 formed on the outer side wall of the annular connecting seat 403 in a circular array, and an insertion tube 601 connected to the support seat 404. A positioning block 602 is inserted into the inside of the insertion tube 601. The positioning block 602 is adapted to the positioning groove 605. One end of the positioning block 602 is movably connected to the inner wall of the insertion tube 601 by a spring. A square through groove 603 is formed through the middle of the outer side of the insertion tube 601. A protrusion 604 is fixedly connected to one end of the outer side of the positioning block 602. The protrusion 604 is connected through the square through groove 603.

In use, the drive motor 801 starts and drives the hexagonal shaft 802 to rotate through the drive pulley and the drive belt. The hexagonal shaft 802 drives the bushing 805 to rotate. The rotation of the bushing 805 drives the drive gear 804 to rotate through the transmission pulley and the drive belt. The rotation of the drive gear 804 drives the rotating shaft 406 to rotate. The rotation of the rotating shaft 406 drives the winding roller held by the clamping assembly 9 to rotate for winding.

[0051] The width adjustment assembly 5 includes multiple connecting sleeves 501 that are embedded and connected to the center of the support base 404 and arranged in a circular array. A connecting screw 502 is connected through the interior of each connecting sleeve 501. One end of the connecting screw 502 is fixedly connected to an annular adjusting seat 503. Two symmetrically distributed connecting blocks 504 are fixedly connected to the inner wall of the annular adjusting seat 503. One end of each connecting block 504 is connected to the same threaded sleeve 505. A support tube 506 is provided between the two support bases 404. Two symmetrically distributed strip-shaped grooves 507 are formed through the center of the outer surface of the support tube 506. The connecting blocks 504 are connected through the strip-shaped grooves 507. The threaded sleeve 505 is located inside the support tube 506. A bidirectional screw 508 is provided inside the support tube 506. Both ends of the bidirectional screw 508 are connected to the two ends of the support tube 506 via bearings. The inner wall of the end is connected through, and the threaded sleeve 505 is threadedly connected to the double-ended screw 508. Both ends of the double-ended screw 508 located outside the support tube 506 are fixedly connected with hexagonal nuts. The middle of the support seat 404 is provided with an adjustment slot corresponding to the hexagonal nuts. When clamping and fixing take-up rollers of different specifications, the device rotates the hexagonal nuts by using an hexagonal wrench. The hexagonal nuts drive the double-ended screw 508 to rotate. The double-ended screw 508 cooperates with the threaded sleeve 505, so that the position of the annular adjustment seat 503 is adjusted. The annular adjustment seat 503 can drive the connecting screw 502 to move, which in turn drives the support seat 404 to move, so that the position between the two support seats 404 is adjusted. Thus, the distance between the two support seats 404 can be adjusted according to the size of the take-up roller, so that the device can adapt to various specifications of take-up rollers.

[0052] In use, the support assembly 1 is installed at the discharge end of the foil-making machine using bolts and other fasteners. This pulls the copper foil produced by the foil-making machine, causing it to pass sequentially through the positioning assembly 2 and the tensioning assembly 3 before reaching the take-up roller support assembly 4. The take-up roller supported on the take-up roller support assembly 4 can then be used to take up the copper foil. During this process, multiple positioning assemblies 2 act on the copper foil, allowing it to move along the positioning assemblies 2, thus ensuring that the copper foil is taken up to the outer center of the take-up roller. The tensioning assembly 3 can adjust the tension of the copper foil, preventing wrinkles from forming during the take-up process. When the copper foil passes through the tensioning assembly 3, it passes sequentially through the guide roller 302 and the tensioning roller. During the conveying process, the tension spring acts on the portal frame 308, causing the portal frame 308 to be subjected to... The downward force, driven by the portal frame 308, causes the tension roller to move, resulting in a downward force on the tension roller. Since the copper foil passes under the tension roller, the tension roller acts on the copper foil, causing it to be under downward force, thus keeping the copper foil in a tensioned state. If the tension spring is insufficient to adjust the tension of the copper foil, the cylinder 303 is extended or retracted. The extension or retraction of the cylinder 303 causes the movable plate 304 to move, thus adjusting the position of the movable plate 304. The movable plate 304 can then drive the movable frame 306 to move, which in turn drives the portal frame 308 to move, thus adjusting the initial position of the tension roller and increasing the adjustment range of the tension of the copper foil. When the copper foil reaches the take-up roller support assembly 4, the take-up roller support assembly 4 is equipped with multiple clamping assemblies 9.

[0053] The clamping assembly 9 holds the take-up roller. When installing the take-up roller, pull the collar 903. The collar 903 slides on the outside of the rotating shaft 406, causing the collar 903 to be misaligned with the turntable 901. At this time, the collar 903 separates from the turntable 901. The intermediate shaft of the take-up roller can then be inserted into the gap between the arc-shaped clamping plates 902. Then, release the collar 903. The collar 903 resets under the action of the return spring and slides on the outside of the rotating shaft 406 until one end of the collar 903 is flush with one end of the turntable 901. At the same time, by controlling the extension of the second electric telescopic rod 702, the arc-shaped clamping plate 902 is pushed to move towards the center, thereby clamping the take-up roller. At this time, the position between the intermediate shaft of the take-up roller and the connecting pipe is fixed, and the installation of the take-up roller is completed.

[0054] When the winding roller winds up the copper foil, the drive motor 801 drives the hexagonal shaft 802 to rotate via the drive pulley and transmission belt. The hexagonal shaft 802 drives the bushing 805 to rotate. The bushing 805 drives the drive gear 804 to rotate via the transmission pulley and transmission belt. The drive gear 804 drives the transmission gear 407 to rotate, which in turn drives the connecting tube to rotate. The connecting tube then drives the intermediate shaft of the winding roller to rotate, thereby achieving the winding of the copper foil.

[0055] When the copper foil on the outer side of the take-up roller has been wound up to a certain quantity, and the take-up roller needs to be replaced, the same method as above is used. The new take-up roller is fixed to a set of clamping components 9 adjacent to the front of the take-up roller to be replaced. The drive motor 801 is controlled to stop rotating. At the same time, the tensioning component 3 is tensioned on the copper foil by controlling the extension and retraction of the cylinder 303 according to the tensioning force detection module. Simultaneously, the second electric telescopic rod 702 corresponding to the extrusion component 7 on the small diameter ring 904 is retracted. The second electric telescopic rod 702 retracts and separates from the arc-shaped clamping plate 902. Then, the first electric telescopic rod 701 corresponding to the extrusion component 7 on the small diameter ring 904 is controlled to retract. The two second electric telescopic rods 702 are retracted to positions where they can be inserted into the two axial reciprocating track grooves 10. Then, the second electric telescopic rods 702 are extended, allowing them to be inserted into the two axial reciprocating track grooves 10. Next, the electromagnetic pin corresponding to the larger diameter ring 904 is extended or retracted, thereby releasing the lock between the fixing plate 408 and the ring 904. Then, the first electric telescopic rod 701 corresponding to the pressing assembly 7 on the smaller diameter ring 904 is repeatedly extended and retracted. Under the action of the axial reciprocating track grooves 10, the collar 903 rotates circumferentially. The rotation of the collar 903, through the limiting lugs, drives the larger diameter ring 904... The extrusion assembly 7 rotates, and the extrusion assembly 7 on the large-diameter ring 904 rotates, driving the take-up roller that needs to be replaced to rotate. Therefore, even if the drive connection between the take-up roller currently being wound and the drive assembly 8 is disconnected during the take-up roller switching process, the winding roller can still continue winding, thus preventing wrinkles from forming on the copper foil being conveyed by the foil-making machine while it is still discharging material due to the disconnection of the drive connection between the winding roller and the drive assembly 8 during the take-up roller switching process. Then, the protrusion 604 is pushed, and the protrusion 604 drives the positioning insert 602 to move, causing the positioning insert 602 to separate from the positioning groove 605. At this time, the support seat 404 and the ring... The limiting position between the connecting seats 403 is released. By rotating the support seat 404, the support seat 404 drives the take-up roller that needs to be replaced and the new take-up roller to rotate. The transmission gear 407 corresponding to the take-up roller that needs to be replaced separates from the drive gear 804. At the same time, the transmission gear 407 corresponding to the new take-up roller meshes with the drive gear 804. Then, the first electric telescopic rod 701 of the extrusion assembly 7 on the small diameter ring 904 is controlled to stop extending and retracting. Then, the copper foil of the take-up roller that is being wound is pasted onto the new take-up roller by adhesive tape. Then, the copper foil is cut by a cutter. Then, the drive motor 801 is controlled to work again, so that the new take-up roller rotates to perform winding.

[0056] This invention, through the cooperation between the clamping component 9, the extrusion component 7, etc., achieves the following: First, the clamping component 9 can adapt to winding rollers of different diameters. Second, during the switching of winding rollers, even if the transmission connection between the winding roller currently being wound and the drive component 8 is disconnected, the winding roller can still continue winding, thus preventing wrinkles from forming on the copper foil being conveyed by the foil-making machine while it is still discharging material due to the disconnection of the transmission connection between the winding roller currently being wound and the drive component 8. Third, even if the drive component 8 malfunctions, the copper foil can still be wound, thus preventing the foil-making machine from stopping and resulting in low production efficiency due to the malfunction of the drive component 8. Fourth, when cutting copper foil and changing winding rollers, the invention avoids the need for machine downtime for replacement as in the prior art, thereby improving production efficiency; it also avoids the process of alignment and correction after cutting.
