Description

Technical Field

[0001] This utility model relates to the field of winding technology, and more specifically, to a deviation correction device and a winding equipment. Background Technology

[0002] In the winding process of battery cell manufacturing, it is usually necessary to precisely and efficiently wind the electrode sheets onto the outermost ring of the cell to ensure the cell's performance and quality. In actual production, in order to meet the specific structural design and performance requirements of the battery cell, the outermost electrode sheet is often designed with one end being relatively longer than the other end to facilitate cutting after winding.

[0003] Among them, the film-coating roller can quickly extend and abut against the next electrode after the previous electrode is wound and cut, so as to ensure that the next electrode can start the winding process accurately and smoothly, thereby ensuring the continuity and stability of the cell winding.

[0004] However, in existing technology, because the tail of the previous electrode cannot fall downstream of the two alignment rollers in time after being cut, the film-coating roller must wait until the tail of the previous electrode has completely detached from between the alignment rollers before it can extend to perform the next electrode placement operation. This increases the overall cell winding cycle, slows down the production line's pace, and reduces the number of cells produced per unit time. Furthermore, for electrodes of different sizes, manual adjustment to the appropriate position is often required, which also leads to low production efficiency. Utility Model Content

[0036] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0037] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] This invention provides a deviation correction device that enables efficient switching between gap-feeding and compression winding of the strip, thereby improving winding efficiency and adjusting the position of the strip. The strip includes, but is not limited to, positive electrode sheets, negative electrode sheets, and separators.

[0040] like Figure 1 As shown, the correction device provided by this utility model includes:

[0041] The first movable seat 1, the second movable seat 2, and the first mounting seat 7 are slidably connected to the first mounting seat 7 along a first direction;

[0042] The first roller 3 is connected between the first movable seat 1 and the second movable seat 2;

[0043] The film-coating roller component 4 includes a slide plate 42 and a second roller 41 connected to the slide plate 42. The slide plate 42 is slidably connected to the first mounting base 7 along a second direction. The second roller 41 is slidably connected to the slide plate 42 along the first direction and connected to the first movable base 1 or the second movable base 2. The second direction is the arrangement direction of the first roller 3 to the second roller 41, and the second direction intersects with the first direction.

[0044] like Figure 1 As shown, the first movable seat 1 and the second movable seat 2 can be made of aluminum alloy profiles to improve their structural stability. Vertical guide rail grooves and horizontal mounting holes can be provided on their opposite sides. High-precision linear guide rail pairs are embedded in the guide rail grooves for sliding connection of the film-coating roller component 4, allowing the film-coating roller component 4 to slide along the guide rail grooves on both sides. The horizontal mounting holes are used to fix the bearing seat of the first roller 3, thereby realizing the assembly of the first roller 3.

[0045] like Figure 1 As shown, the first mounting base 7 can be a frame structure, which facilitates the sliding connection of the first movable base 1 and the second movable base 2 along the first direction, i.e., the Y direction in the figure, which is also the width direction of the electrode sheet, while also improving the structural stability of the first mounting base 7. The frame structure of the first mounting base 7 can be an integral structure or a split structure, facilitating different winding requirements.

[0046] In one embodiment, the first roller 3 can be rotatably mounted between the first movable seat 1 and the second movable seat 2, that is, the first roller 3 can rotate to facilitate the pressing and positioning of the material strip. For example, a second driving member 8 can be provided, which includes, but is not limited to, a rotary motor and a rotary cylinder, and the driving end of the second driving member 8 is connected to the first roller 3 in a transmission connection so that the second driving member 8 can drive the first roller 3 to rotate.

[0047] like Figure 1 As shown, the film-forming roller component 4 includes a slide plate 42. Slider blocks are provided on both sides of the slide plate 42, and these sliders are slidably engaged with vertical guide grooves on the first mounting base 7, thereby enabling the slide plate 42 to slide along the second direction of the first mounting base 7, i.e., the X direction in the figure. This second direction, i.e., the X direction in the figure, is also the arrangement direction of the first roller 3 to the second roller 41, facilitating the contact and separation of the second roller 41 with the first roller 3.

[0048] like Figure 1 As shown, the film-coating roller component 4 also includes a second roller 41, which can be mounted to the slide plate 42 via a roller mounting seat so that the second roller 41 can slide along the first movable seat 1 and the second movable seat 2 together with the slide plate 42.

[0049] The second roller 41 is arranged in parallel with the first roller 3, that is, their axes are parallel. The sliding direction of the slide plate 42, that is, the X direction in the figure, is parallel to the arrangement direction of the second roller 41 and the first roller 3, so that the slide plate 42 can drive the second roller 41 to move closer to or away from the first roller 3.

[0050] Specifically, when the slide plate 42 drives the second roller 41 away from the first roller 3 in the second direction until the film-coating roller component 4 is in the first position, a certain gap is formed between the second roller 41 and the first roller 3. At this time, the material strip can pass through the gap quickly and freely without contact, so as to facilitate the pressing and winding of the next material strip, thereby improving the winding efficiency. At the same time, it can also avoid the risk of the second roller 41 and the first roller 3 causing scratches or abrasions to the material strip, which helps to improve the yield of battery cell production.

[0051] The first position of the film-coating roller component 4 can be adjusted according to the actual size of the material strip, thereby adjusting the gap between the second roller 41 and the first roller 3 to facilitate the rapid passage of the corresponding material strip and improve the utilization rate of the correction device.

[0052] When the slide plate 42 drives the second roller 41 to approach the first roller 3 in the second direction until the film-coating roller component 4 is in the second position, the second roller 41 abuts against the first roller 3. At this time, the material strip is pressed and fixed between the second roller 41 and the first roller 3 to facilitate the winding process.

[0053] The winding process includes unwinding and rewinding processes. That is, the correction device can be applied to the unwinding process of the strip or the rewinding process of the strip, and can achieve efficient switching between the strip's gap insertion and tight winding.

[0054] In one embodiment, the clamping force between the second roller 41 and the first roller 3 can be adjusted to control the tension fluctuation of the clamped strip, thereby improving the uniformity of the tension applied to the strip and helping to avoid the risk of misalignment during multiple windings.

[0055] In one embodiment, the sliding reliability of the film-coating roller component 4 can also be controlled to ensure that the second roller 41 and the first roller 3 remain parallel during the sliding process, which can avoid stress concentration at the edge of the material strip caused by the tilt of the second roller 41, thereby helping to improve the flatness of the product end face.

[0056] Furthermore, the second roller 41 is connected to the second mounting base 43 and then to the push plate 44. Two rollers on the push plate 44 abut against the first movable base 1 and the second movable base 2, respectively, forming a power transmission path of first movable base 1 and second movable base 2 - rollers - push plate 44 - second roller 41. When the first movable base 1 or the second movable base 2 slides along the first direction, the rollers and push plate 44 drive the second roller 41 to slide along the first direction on the slide plate 42. Simultaneously, the connected first roller 3 also slides along the first direction, allowing the first roller 3 and the second roller 41 to move together along the first direction and adjust the position of the material strip, thereby improving the reliability of subsequent winding.

[0057] Optionally, the film-coating roller component 4 has a first position and a second position, and when the film-coating roller component 4 is in the first position, there is a gap between the second roller 41 and the first roller 3;

[0058] When the film-coating roller component 4 is in the second position, the second roller 41 abuts against the first roller 3.

[0059] Specifically, when the slide plate 42 drives the second roller 41 away from the first roller 3 in the second direction until the film-coating roller component 4 is in the first position, a certain gap is formed between the second roller 41 and the first roller 3. At this time, the material strip can pass through the gap quickly and freely without contact, so as to facilitate the pressing and winding of the next material strip, thereby improving the winding efficiency. At the same time, it can also avoid the risk of the second roller 41 and the first roller 3 causing scratches or abrasions to the material strip, which helps to improve the yield of battery cell production.

[0060] When the slide plate 42 drives the second roller 41 to approach the first roller 3 in the second direction until the film-coating roller component 4 is in the second position, the second roller 41 abuts against the first roller 3. At this time, the material strip is pressed and fixed between the second roller 41 and the first roller 3 to facilitate the winding process.

[0061] Optionally, it also includes a third driving member 5, which is disposed on the first mounting base 7, and the driving end of the third driving member 5 is connected to the slide plate 42.

[0062] like Figure 1 As shown, the third drive component 5 includes, but is not limited to, a linear motor and a linear cylinder. The drive end of the third drive component 5 is connected to the slide plate 42, so that the third drive component 5 can drive the slide plate 42 and the second roller 41 to slide together along the second direction, so that the film-coating roller component 4 can switch between the first position and the second position, so as to realize the efficient switching between material strip gap insertion and pressing winding, thereby improving winding efficiency.

[0063] Optionally, it also includes a first driving member 6, the driving end of the first driving member 6 being connected to the first movable seat 1.

[0064] like Figure 1 As shown, the first driving component 6 includes, but is not limited to, a linear motor and a linear cylinder. The driving end of the first driving component 6 is connected to the first movable seat 1 to form driving force transmission paths of the first driving component 6-first movable seat 1-first roller 3-second movable seat 2 and the first driving component 6-first movable seat 1-second roller 41, so that the first roller 3 and the second roller 41 can move together in the first direction and realize the position adjustment of the material strip, thereby improving the reliability of subsequent winding.

[0065] Since the second roller 41 is connected to the second mounting base 43 and the push plate 44, the two rollers on the push plate 44 abut against the first movable base 1 and the second movable base 2 respectively, so as to form a power transmission path of first driving member 6 - first movable base 1 and second movable base 2 - rollers - push plate 44 - second roller 41. When the first driving member 6 drives the first movable base 1, the first roller 3 and the second movable base 2 to move together in the first direction, the first movable base 1 or the second movable base 2 can drive the second roller 41 to slide on the slide plate 42 in the first direction through the rollers and the push plate 44, so that the second roller 41 can move synchronously with the first roller 3, thereby facilitating the adjustment of the material belt position.

[0066] Optionally, the film-coating roller component 4 further includes a second mounting base 43 and a pusher plate 44. The pusher plate 44 is slidably connected to the second mounting base 43 along the first direction, and the second roller 41 is connected to the second mounting base 43 and connected to the pusher plate 44. The pusher plate 44 is provided with a first transmission member 441 and a second transmission member 442. The first transmission member 441 abuts against the first movable seat 1, and the second transmission member 442 abuts against the second movable seat 2.

[0067] like Figures 2 to 4 As shown, the second mounting base 43 is fixedly connected to the slide plate 42, and the second mounting base 43 is used to assemble the second roller 41 to facilitate the rotation of the second roller 41. The push plate 44 is slidably connected to the second mounting base 43 along a first direction. For example, a guide rail is provided on one of the push plate 44 and the second mounting base 43, and a slider adapted to the guide rail is provided on the other of the push plate 44 and the second mounting base 43, so that the push plate 44 can be slidably assembled through the sliding engagement of the slider and the guide rail.

[0068] like Figures 2 to 4As shown, a first transmission member 441 and a second transmission member 442 can be respectively provided at the two ends of the push plate 44. The first transmission member 441 is used to abut against the first movable seat 1, and the second transmission member 442 is used to abut against the second movable seat 2, so as to form a power transmission path of first movable seat 1 and second movable seat 2 - first transmission member 441 and second transmission member 442 - push plate 44 - second roller 41, thereby driving the second roller 41 to move synchronously with the first roller 3 and realizing the adjustment of the material belt position.

[0069] In one embodiment, the first transmission member 441 and / or the second transmission member 442 are rollers, which roll against the corresponding movable seats. That is, the rollers can form a rolling engagement with the corresponding movable seats. During the process of the first driving member 6 driving the first movable seat 1, the first roller 3, and the second movable seat 2 to move together in the first direction, the first movable seat 1 and the second movable seat 2 can apply a certain driving force to the abutting rollers, and drive the rollers, the push plate 44, and the second roller 41 to move together in the first direction, thereby driving the second roller 41 to move synchronously with the first roller 3 and realizing the adjustment of the material belt position.

[0070] In one embodiment, the first transmission member 441 and / or the second transmission member 442 are transmission sliders, which abut against the inner wall of the corresponding movable seat. At this time, as the first driving member 6 drives the first movable seat 1, the first roller 3, and the second movable seat 2 to move together along the first direction, the first movable seat 1 and the second movable seat 2 can apply a certain compressive force to the abutting transmission sliders, and drive the transmission sliders, the push plate 44, and the second roller 41 to move axially along the first direction, thereby enabling the second roller 41 to move synchronously with the first roller 3 and achieving adjustment of the material belt position.

[0071] Optionally, the first transmission member 441 and / or the second transmission member 442 are rollers;

[0072] And / or, the push plate 44 is further provided with a third transmission member 443 and a fourth transmission member 444, the third transmission member 443 being able to abut against the first movable seat 1, and the fourth transmission member 444 being able to abut against the second movable seat 2.

[0073] like Figures 2 to 4 As shown, the first transmission component 441 and / or the second transmission component 442 are rollers, which roll against the corresponding movable seats. That is, the rollers can form a rolling engagement with the corresponding movable seats. During the process of the first driving component 6 driving the first movable seat 1, the first roller 3 and the second movable seat 2 to move together along the first direction, the first movable seat 1 and the second movable seat 2 can apply a certain driving force to the rollers that are abutting each other, and drive the rollers, the push plate 44 and the second roller 41 to move together axially along the first direction, thereby driving the second roller 41 to move synchronously with the first roller 3 and realizing the adjustment of the material belt position.

[0074] Furthermore, the rolling contact between the roller and the corresponding moving seat can reduce the risk of damage to the transmission components while realizing the transmission of driving force between the moving seat and the roller through the smooth contact between the two.

[0075] like Figures 2 to 4 As shown, a third transmission member 443 and a fourth transmission member 444 can also be provided on the push plate 44. The third transmission member 443 is close to the first transmission member 441, and the fourth transmission member 444 is close to the second transmission member 442. The first transmission member 441 and the second transmission member 442 can be located at the top of the push plate 44, and the third transmission member 443 and the fourth transmission member 444 can be located on the side of the push plate 44, so that at least the first transmission member 441 and the second transmission member 442 always abut against the inner wall of the corresponding moving seat. The third transmission member 443 and the fourth transmission member 444 can adapt to the complex shape of the moving seat, thereby cooperating with the first transmission member 441 and the second transmission member 442 to improve the reliability of driving force transmission.

[0076] Optionally, the first transmission member 441 and the second transmission member 442 are located on top of the push plate 44.

[0077] like Figures 2 to 4 As shown, the first transmission member 441 and the second transmission member 442 can be located on the top of the push plate 44, and the third transmission member 443 and the fourth transmission member 444 can be located on the side of the push plate 44, so that at least the first transmission member 441 and the second transmission member 442 are always in contact with the inner wall of the corresponding moving seat, while the third transmission member 443 and the fourth transmission member 444 can adapt to the complex shape of the moving seat, thereby cooperating with the first transmission member 441 and the second transmission member 442 to improve the reliability of the driving force transmission.

[0078] Optionally, the pusher plate 44 is provided with a connecting part 45, and the film-coating roller component 4 further includes a shaft 46, the shaft 46 is inserted into the second mounting base 43, and the shaft 46 is slidably connected to the bushing 431 of the second mounting base 43, the connecting part 45 is fixedly connected to the shaft 46, and the second roller 41 is rotatably sleeved on the shaft 46.

[0079] like Figure 2 and Figure 3 As shown, the shaft 46 passes through the second mounting base 43 and extends from both ends, with connecting parts 45 fixedly sleeved at both ends of the shaft 46. The shaft 46 is slidably connected to the bushing 431 of the second mounting base 43, allowing the shaft 46 to slide axially relative to the second mounting base 43.

[0080] The second roller 41 is rotatably mounted on the shaft 46. On the one hand, the second roller 41 can rotate along the shaft 46. On the other hand, it can also form a driving force transmission path of push plate 44-connecting part 45-shaft 46-second roller 41. So that when the first driving member 6 drives the first moving seat 1, the first roller 3 and the second moving seat 2 to move together in the first direction, the first moving seat 1 and the second moving seat 2 can apply a certain driving force to the opposing rollers, and drive the rollers, push plate 44 and second roller 41 to move together in the first direction. In this way, the second roller 41 can move synchronously with the first roller 3 and realize the adjustment of the material belt position.

[0081] Among them, the axes of push plate 44 and shaft 46 are parallel, and the axes of push plate 44, shaft 46 and second roller 41 are parallel to ensure the uniformity of driving force transmission, thereby ensuring that the second roller 41 always remains parallel to the first roller 3 during the movement.

[0082] Optionally, the film-coating roller component 4 further includes a first connecting plate 47 and a fourth driving member 48. The first connecting plate 47 is disposed on the slide plate 42, the fourth driving member 48 is disposed on the first connecting plate 47, and the driving end of the fourth driving member 48 is connected to the second mounting base 43.

[0083] Driven by the fourth driving member 48, the second mounting base 43 can drive the second roller 41 to slide along the second direction.

[0084] like Figure 2 and Figure 4 As shown, the first connecting plate 47 is fixedly connected to the slide plate 42 to facilitate the installation of the fourth drive member 48 using the first connecting plate 47. The fourth drive member 48 includes, but is not limited to, a linear motor and a linear cylinder. The driving direction of the fourth drive member 48 is parallel to the arrangement direction of the first roller 3 and the second roller 41, so that the fourth drive member 48 can drive the second roller 41 to approach the first roller 3 until it abuts against the first roller 3.

[0085] First, the slide plate 42 moves the second roller 41 closer to the first roller 3 until the film-coating roller assembly 4 is in the second position, so that the second roller 41 and the first roller 3 are approximately in contact. That is, the film-coating roller assembly 4 moves as a whole to the second position. Then, the fourth drive member 48 moves the second roller 41 closer to the first roller 3 in the second direction until it elastically contacts the first roller 3. This allows for two adjustments to ensure the clamping force between the second roller 41 and the first roller 3, so that the strip can be pressed and fixed between the second roller 41 and the first roller 3 to facilitate the winding process.

[0086] Optionally, the first mounting base 7 includes four second connecting plates 71 that are opposite each other in pairs, wherein each pair of opposite second connecting plates 71 is provided with a guide rod 72, and the first movable base 1 and the second movable base 2 are slidably connected to the corresponding guide rod 72.

[0087] like Figure 1 As shown, the first mounting base 7 includes four second connecting plates 71, which form a frame structure. Typically, the first movable base 1 and the second movable base 2 are slidably connected to the inner sides of two opposing long sides of the frame structure along a first direction to facilitate the movement of the film-coating roller component 4 along the length of the frame.

[0088] At least one guide rod 72 can be provided on each of the two opposing second connecting plates 71 of the first mounting base 7. The guide rod 72 extends into the corresponding movable seat to form a sliding connection, so that the movable seat can move axially along the guide rod 72, that is, move in the first direction, thereby guiding the movement of the first movable seat 1 and the second movable seat 2.

[0089] This utility model also provides a winding device, including the aforementioned correction device, and the winding device should have all the technical effects of the correction device.

[0090] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0091] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
