Description

Technical Field

[0001] This utility model relates to the field of electrode drying technology, and in particular to an electrode winding device for a dryer. Background Technology

[0002] Lithium-ion battery electrodes are primarily dried using a vacuum drying chamber. The drying process involves placing the electrodes to be dried inside the chamber, evacuating the chamber, heating it, and setting a pre-defined drying time to dry the electrodes. Therefore, if the drying chamber is large, it requires a large amount of protective gas, and the evacuation time is also longer, significantly reducing the equipment's production efficiency. To save space in the vacuum drying chamber, existing technologies typically use multiple tension rollers, allowing the electrode rolls to be wound multiple times between the rollers. This utilizes the overlapping area of ​​the unwinding and winding mechanisms, improving space utilization.

[0003] However, since the tensioning wheel is fixed in position and the tensioning wheel assembly is densely packed in the vacuum drying chamber in order to make full use of space, it is inconvenient to operate when the electrode roll is first wound around the tensioning wheel.

[0004] Considering the above shortcomings, there is an urgent need to develop an electrode winding device that can both improve space utilization and facilitate electrode winding onto the machine. Utility Model Content

[0005] This invention provides an electrode winding device for a dryer, which solves the problems of existing electrode winding devices, such as inability to make good use of space, easy heat loss, and poor auxiliary heating effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A deflector winding device for a dryer, characterized in that it comprises: an unwinding roller, a first correction fixing roller group, a fixing roller, a second correction fixing roller group, and a take-up roller, which are sequentially rotatably mounted on a first mounting bracket; and a first adjusting roller and a second adjusting roller, which are sequentially arranged on a second mounting bracket; the second mounting bracket is staggered with the first mounting bracket and can be vertically raised and lowered; the first adjusting roller and the second adjusting roller pass through the first correction fixing roller, the fixing roller, and between the fixing roller and the second correction fixing roller, respectively, driven by the second mounting bracket.

[0008] Preferably, the unwinding roller and the winding roller are located at the lower ends of the left and right sides of the first mounting bracket, and the axes of the unwinding roller and the winding roller are on the same horizontal plane.

[0009] Preferably, the first correction fixing wheel group, the fixing roller, and the second correction fixing wheel group are located on the upper part of the first mounting bracket and are respectively a certain distance from the left and right sides.

[0010] Preferably, the first and second correction fixing wheel sets each include two rollers and a pole roll translation structure.

[0011] Preferably, the surface of each roller is polished.

[0012] Preferably, the first adjusting roller and the second adjusting roller are both installed on the left and right sides of the bottom end of the second mounting bracket.

[0013] Preferably, the axes of the first adjusting roller and the second adjusting roller are located in the same plane.

[0014] Preferably, the surfaces of the first adjusting roller and the second adjusting roller are covered with a rubber layer.

[0015] Preferably, the second mounting bracket is raised and lowered via a lead screw and slider structure.

[0016] The beneficial effects of this utility model are:

[0017] 1. The operation is simple because it only requires the electrode sheet to pass over the two horizontally set first fixed rollers and fixed rollers and be wound onto the take-up roller.

[0018] 2. The height of the second mounting bracket can be automatically adjusted to enable multiple winding and tensioning of the electrode sheets in the drying chamber, greatly improving the adjustment convenience and drying efficiency of the drying equipment. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] In the prior art, since the tensioning wheel is fixed in position and the tensioning wheel group is densely arranged in the vacuum drying chamber in order to make full use of space, it is inconvenient to operate the electrode roll when it is fed and wound around the tensioning wheel.

[0028] To address the aforementioned shortcomings, this embodiment provides an electrode winding device for a dryer, which can both improve space utilization and facilitate electrode winding onto the machine.

[0029] Reference Figures 1-4This embodiment provides a deflection coil winding device for a dryer, including an unwinding roller 1, a first correction fixing wheel group 2, a fixing roller 3, a second correction fixing wheel group 4, and a take-up roller 5. The unwinding roller 1, the first correction fixing wheel group 2, the fixing roller 3, the second correction fixing wheel group 4, and the take-up roller 5 are sequentially rotatably mounted on a first mounting bracket 6, forming a continuous transmission path. The unwinding roller 1 and the take-up roller 5 are located at the lower ends of the left and right sides of the first mounting bracket 6, and their axes are on the same horizontal plane. The first correction fixing wheel group 2, the fixing roller 3, and the second correction fixing wheel group 4 are located at the upper part of the first mounting bracket, and are respectively at a certain distance from the left and right sides. The axes of the first correction fixing wheel group 2, the fixing roller 3, and the second correction fixing wheel group 4 are also set on the same horizontal plane. The surface of each roller is polished to avoid scratching the material. Both the first and second correction fixing wheel sets 2 and 4 include two rollers and an electrode roll translation structure. The first and second correction fixing wheel sets 2 and 4 can adjust the transmission position of the electrode roll during unwinding and rewinding based on the deviation of the electrode roll during unwinding and rewinding, respectively. The electrode roll translation structure can use a cylinder-driven translation table. The two rollers are mounted parallel to each other on the translation table. When the electrode roll deviates left or right during transmission, a sensor detects the edge position of the electrode roll. The control system drives the cylinder to move the translation table laterally based on the detection signal, thereby adjusting the transmission path of the electrode roll and ensuring that the electrode roll always runs stably along the set trajectory. The surface of the fixing roller 3 is covered with a high-temperature resistant silicone layer with a thickness of 3-5mm. This increases the friction between the roller and the electrode roll, preventing slippage during transmission, and also acts as a buffer when the electrode roll is tensioned, preventing damage due to excessive local pressure.

[0030] A first adjusting roller 7 and a second adjusting roller 8 are also provided on the second mounting bracket 9. The first adjusting roller 7 and the second adjusting roller 8 are both installed on the left and right sides of the bottom end of the second mounting bracket 9. The first adjusting roller 7 is located between the first correction fixing wheel group 2 and the fixed roller 3, and the second adjusting roller 8 is located between the fixed roller 3 and the second correction fixing wheel group 4. The second mounting bracket 9 and the first mounting bracket 6 are staggered. The second mounting bracket 9 is slidably connected to the slide rail of the first mounting bracket 6 by a slider. The slider is connected to the lead screw transmission mechanism. The lead screw driven by the servo motor can drive the slider to move up and down along the slide rail, thereby adjusting the height of the first adjusting roller 7 and the second adjusting roller 8.

[0031] Preferably, the surfaces of the first adjusting roller 7 and the second adjusting roller 8 are covered with a rubber layer to increase friction and prevent slippage. The axes of the first adjusting roller 7 and the second adjusting roller 8 are also located on the same plane; the first adjusting roller 7, the second adjusting roller 8, and the third adjusting roller are staggered with the first corrective fixing wheel group 2, the fixed roller 3, and the second corrective fixing wheel group 4 in vertical space. This staggered layout allows the electrode roll to form an S-shaped path during transmission, which can effectively increase the contact area of ​​the electrode roll in the drying chamber and improve the drying efficiency of the electrode roll. At the same time, the S-shaped path design can also generate a certain tension on the electrode roll, keeping the electrode roll in a stable state during transmission and avoiding wrinkles or displacement caused by slack.

[0032] The working process of this embodiment is as follows: When the electrode roll is loaded into the unwinding roller 1, the electrode sheet first passes through the first straightening fixed roller group 2, the top of the fixed roller 3, and the second straightening fixed roller group 4 in sequence, and reaches the take-up roller 5; after the electrode sheet is pre-wound several times on the take-up roller, the equipment is started, and the servo motor drives the lead screw to rotate slowly, driving the second mounting bracket 9 to move downward along the guide rail. At this time, the first adjusting roller 7 and the second adjusting roller 8 pass through the gap between the first straightening fixed roller group 2, the fixed roller 3, and the second straightening fixed roller group 4, respectively, to realize the multiple winding of the electrode sheet in a fixed space.

[0033] Since manual operation only requires the electrode sheet to pass over the two horizontally set first fixed rollers and fixed rollers and be wound onto the take-up roller, the operation is simple; subsequently, by adjusting the height of the second mounting bracket, the electrode sheet can be automatically wound and tensioned multiple times in the drying chamber, thereby improving the drying efficiency of the drying equipment.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
