Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator manufacturing technology, and in particular to a coating machine end winding device. Background Technology

[0002] There is a huge market demand for new energy batteries in China. Currently, most lithium battery separator processing uses single-sided multiple coating, or coating one side on a production line, drying it, coating the other side, and drying it again. Regardless of the method, the coated lithium battery separator needs to be dried in a drying machine before being rolled up for use. To improve drying efficiency, some drying machines are quite long. In addition, the lithium battery separator will deform due to thermal expansion and contraction, causing the lithium battery separator to shift after leaving the drying machine, affecting the neatness of the roll. Therefore, there is a need for a winding device that can automatically correct the offset of the lithium battery separator to ensure the neatness of the roll. Utility Model Content

[0038] The present invention will be described in detail below with reference to specific embodiments.

[0039] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0040] like Figures 1 to 17 As shown, this utility model provides an end-of-line winding device for a coating machine, including a frame 1. A set of guiding wheels 2 is mounted on the frame 1. The guiding wheel set 2 includes a support shaft 20, a rotating shaft 21, floats 22, a linkage plate 27, an inclined plate 25, an inclined drive component 24, and a support plate 23. The rotating shaft 21 is mounted on the support shaft 20 and can rotate on the support shaft 20. Multiple sets of floats 22 are mounted on the rotating shaft 21 and can slide on the rotating shaft 21. The sliding direction of the floats 22 is relative to the center of the support shaft 20. The axes are parallel; multiple sets of floating plates 22 are connected to each other by linkage plates 27, and the floating plates 22 are provided with limit grooves 221, with limit rings 26 fitted at the limit grooves 221; tilting plates 25 are respectively installed at both ends of the support shaft 20, and the tilting plates 25 are installed on the support shaft 20 by outer spherical ball bearings; the support shaft 20 is installed on the frame 1 by a support plate 23, and multiple sets of tilting drive components 24 are evenly arranged on the support plate 23, and the tilting drive components 24 are connected to the tilting plates 25; a correction sensor is provided on the frame 1.

[0041] In this embodiment, the rotating shaft 21 is provided with multiple sets of support wheels 210, and the float plate 22 is provided with corresponding grooves 222 for the support wheels 210; auxiliary wheels 220 are provided at both ends of the float plate 22, and the auxiliary wheels 220 abut against the inclined plate 25.

[0042] In this embodiment, a coil is provided in the rotating shaft 21, allowing the shaft 21 to rotate around the support shaft 20 after being energized. The rotating shaft 21 can drive the lithium battery separator to pass over it. When the correction sensor detects that the lithium battery separator is misaligned, the tilting drive 24 drives the tilting plate 25 to tilt. The tilting angle adjusts automatically according to the misalignment angle of the lithium battery separator. The tilted plate 25 can drive the float plate 22 to shift left and right, thereby counteracting the misalignment of the lithium battery separator. In this embodiment, the tilting drive 24 is connected to the tilting plate 25 through a universal joint sleeve. Multiple evenly distributed tilting drive 24s allow the tilting plate 25 to tilt at any position and angle to adapt to different working requirements. Under the action of the linkage plate 27, multiple float plates 22 can be fitted onto the outside of the rotating shaft 21. At the same time, a single float plate 22 can slide freely without driving other float plates 22, ensuring that the float plates 22 can accurately perform the correction operation.

[0043] The auxiliary wheel 220 on the edge of the float plate 22 can reduce the friction between the float plate 22 and the inclined plate 25. When the rotating shaft 21 rotates, the float plate 22 on the rotating shaft 21 will rotate together with the rotating shaft 21. While the float plate 22 is rotating, the auxiliary wheel 220 will also roll on the inclined plate 25. When the inclined plate 25 is tilted, under the action of the auxiliary wheel 220, the float plate 22 can move in the direction of the central axis of the support shaft 20 while rotating.

[0044] With the above design, the support wheel 210 on the rotating shaft 21 can provide support for the float 22, and at the same time reduce the friction between the float 22 and the rotating shaft 21, so that the float 22 can slide smoothly on the rotating shaft 21. The slide groove 222 on the float 22 can limit the movement, so that the float 22 can rotate together with the rotating shaft 21.

[0045] With the above design, the limiting ring 26 on the float 22 can lock the float 22 onto the rotating shaft 21. When the tilting plate 25 is offset, the limiting ring 26 can also offset with the float 22 under its own elasticity, ensuring that the float 22 can always be tightly attached to the rotating shaft 21. At the same time, the limiting ring 26 can also prevent the float 22 from taking the linkage plate 27 away during the swinging process.

[0046] In this embodiment, a tension adjustment assembly 3 is provided on the frame 1. The tension adjustment assembly 3 includes a slide rod 30, a slide block, a tension elastic element 32, and a tension adjustment roller 31. A tension groove is provided on the frame 1. The slide rod 30 is installed in the tension groove, and the slide block is installed on the slide rod 30. The slide block can slide on the slide rod 30. The tension elastic element 32 is sleeved on the slide rod 30. One end of the tension elastic element 32 abuts against the slide block, and the other end abuts against the tension groove.

[0047] With the above design, under the action of the tensioning elastic element 32, the tensioning adjustment roller 31 can adjust the tension of the lithium battery separator, ensuring that the lithium battery separator is flat and stable enough during transportation.

[0048] In this embodiment, an active feeding assembly 4 is provided on the frame 1. The active feeding assembly 4 includes an auxiliary roller 41, a feeding roller 40, and a lifting frame 42. The feeding roller 40 is fixedly installed on the frame 1, the auxiliary roller 41 is installed below the feeding roller 40, and the lifting frame 42 is installed on the frame 1. The lifting frame 42 is used to control the auxiliary roller 41 to move closer to or away from the feeding roller 40. Multiple sets of guide rollers 6 are provided on the frame 1.

[0049] With the above design, the user can adjust the distance between the auxiliary roller 41 and the feeding roller 40 by rotating the lifting frame 42, so as to ensure that the auxiliary roller 41 can stick the lithium battery separator to the feeding roller 40. Under the drive of the feeding roller 40, the lithium battery separator output from the drying equipment can stably enter the frame 1.

[0050] In this embodiment, a roll assembly 5 is provided on the frame 1. The roll assembly 5 includes a support frame 50, a lifting drive 51, a lifting frame 52, a connecting frame 520, a drive unit, and a load-bearing unit. The support frame 50 is mounted on the frame 1, and the load-bearing unit is mounted on the support frame 50. The load-bearing unit is used to place the rollers for roll assembly. The lifting drive 51 is mounted in the support frame 50 and is used to drive the lifting frame 52 to move up and down on the support frame 50. The connecting frame 520 is mounted in the lifting frame 52 and can slide in the lifting frame 52. The drive unit is mounted on the connecting frame 520 and is located directly above the load-bearing unit. The drive unit is used to drive the rollers for roll assembly on the load-bearing unit to rotate.

[0051] In this embodiment, the driving unit includes a rotary drive 53 and a pressing shaft 54. Both the rotary drive 53 and the pressing shaft 54 ​​are mounted on the connecting frame 520. The rotary drive 53 is used to drive the pressing shaft 54 ​​to rotate, and the pressing shaft 54 ​​is used to drive the roller for the coil to rotate.

[0052] In this embodiment, the bearing part includes a bearing frame 56 and a bearing roller 57. The bearing frame 56 is detachably mounted on the support frame 50, and the bearing roller 57 is mounted on the bearing frame 56. The bearing roller 57 is used to place the roller for the coil material.

[0053] In this embodiment, the connecting frame 520 is provided with a limiting roller 55 on the side away from the drive unit; the lifting frame 52 is provided with a limiting rod 58, the connecting frame 520 can slide on the limiting rod 58, and a limiting elastic member 59 is sleeved on the limiting rod 58. One end of the limiting elastic member 59 abuts against the connecting frame 520, and the other end abuts against the lifting frame 52.

[0054] With the above design, during the winding process, the clamping shaft 54 ​​presses the lithium battery separator onto the winding roller. As the number of lithium battery separators on the roller increases, the diameter of the separator roll increases. As the number of separator rolls increases, the connecting frame 520 slowly rises. Under the action of the limiting elastic element 59, the clamping shaft 54 ​​can always remain in close contact with the separator roll. The rotation drive 53 drives the clamping shaft 54 ​​to rotate the separator roll. Since the separator roll rotates passively, even if the diameter of the separator roll increases, the winding speed will not change, ensuring that the lithium battery separator can be transported at a uniform speed in the frame 1.

[0055] With the above design, when the material roll needs to be removed, the lifting drive 51 controls the lifting frame 52 to lift the pressing shaft 54, making it convenient for workers to pick up and put down the material roll or roller. After replacing the empty roller, the lifting drive 51 drives the pressing shaft 54 ​​to press down again, ensuring that the lithium battery separator can be tightly rolled onto the roller during the subsequent winding process.

[0056] The coating machine end winding device provided by this utility model, compared with the prior art, when the lithium battery separator is deviated, the tilting drive 24 drives the tilting plate 25 to tilt the floating plate 22 left and right. The tilted floating plate 22 can straighten the deviated lithium battery separator and ensure that the lithium battery separator is in the center position. When winding, the lifting drive 51 drives the pressing shaft 54 ​​to press the lithium battery separator on the winding roller, so that the lithium battery separator on the roller is flat and compact enough.

[0057] Where there is no conflict, the above embodiments and features can be combined with each other.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
