Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery winding machine technology, specifically a lithium battery winding machine with regularized sides. Background Technology
[0002] A lithium battery winding machine is a specialized piece of equipment used to manufacture lithium batteries, playing a crucial role in lithium battery production. Through the perfect coordination of these processes, the lithium battery winding machine can produce lithium battery products with stable performance, high quality, and long lifespan.
[0003] As disclosed in the patent announcement CN213988968U, a lithium battery winding machine includes a machine body. A winding mechanism is fixedly installed on the front of the machine body, and a housing is fixedly connected to the bottom of the machine body. Support blocks are fixedly connected to the four corners of the bottom of the housing. This utility model achieves the advantage of easy movement of the lithium battery winding machine by setting up a housing, support blocks, through grooves, a fixing plate, a stepper motor, a threaded rod, a threaded block, a push-pull rod, a connecting block, a lifting plate, a support column, a roller body, a bearing, a first sliding groove, a first sliding block, a second sliding groove, and a second sliding block in cooperation with each other. When the lithium battery winding machine needs to be moved due to changes in the processing flow, the rollers can be extended directly to support the lithium battery winding machine, and then the worker can push the lithium battery winding machine to move it. This saves time and effort for workers, reduces their labor intensity, and meets their usage needs.
[0004] However, this utility model lacks a convenient roll covering mechanism and flexible limiting measures, which makes it inconvenient to ensure the flatness and compactness of the roll during the winding operation. To address this, we propose a lithium battery winding machine with regular side edges, which solves the roll covering and winding limiting problems of this utility model and improves its effectiveness and practicality. Utility Model Content
[0005] The purpose of this invention is to provide a lithium battery winding machine with regular side edges to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

The bottom end of the connecting column penetrates the strip plate and is fixedly connected to the pressing plate. Limiting rods are slidably connected through both ends of the lifting plate. A spring is sleeved on the outside of the limiting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1.

This ensures that the roll material has a certain tensile stress during winding, thereby ensuring the density of the winding and avoiding wrinkles, thus improving the production quality of the winding machine.
[0015] 2. This lithium battery winding machine with regular side edges, through the limiting sleeve set in the winding mechanism and the external threads set on the outer side of both ends of the winding needle, allows the limiting distance of the winding needle to be flexibly adjusted according to the required winding width, which improves the flexibility of the winding machine and expands its application range. At the same time, it also further ensures the winding neatness. Attached Figure Description

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 As shown, this utility model provides a technical solution:
[0023] A lithium battery winding machine with regularized sides includes a control cabinet 100. An unwinding mechanism is fixedly installed on one side of the control cabinet 100, a pressing mechanism is installed on one side of the unwinding mechanism, and a winding mechanism is installed on one side of the pressing mechanism. The pressing mechanism includes a first fixed plate 200 and a second fixed plate 201. A strip plate 202 is fixedly connected between the first fixed plate 200 and the second fixed plate 201. A lifting plate 203 is installed at the top of the strip plate 202, and a connecting post 204 is fixedly installed at the bottom end of the lifting plate 203. The bottom end of the connecting post 204 penetrates the strip plate 202 and is fixedly connected to... The pressing plate 205 and the lifting plate 203 are connected by a limit rod 206 through both ends. A spring 207 is sleeved on the outside of the limit rod 206. The bottom end of the spring 207 is fixedly connected to the top surface of the strip plate 202, and its top end is fixedly connected to the bottom surface of the lifting plate 203. A guide roller 208 is provided directly below the strip plate 202. The two ends of the guide roller 208 are rotatably connected to the first fixed plate 200 and the second fixed plate 201, respectively. The winding mechanism includes a winding needle 300. The outer sides of both ends of the winding needle 300 are provided with external threads 301. The external threads 301 are threadedly connected to the limit sleeve 302.
[0024] In this embodiment, preferably, the winding mechanism further includes a third fixing plate 303 and a fourth fixing plate 304, and the two ends of the winding needle 300 are rotatably connected to the third fixing plate 303 and the fourth fixing plate 304 respectively.
[0025] In this embodiment, preferably, the end of the winding needle 300 near the control cabinet 100 is fixedly connected to the drive shaft 305, one end of the drive shaft 305 is fixedly connected to the output end of the servo motor 306, and the servo motor 306 is fixedly installed inside the control cabinet 100.
[0026] In this embodiment, preferably, the first fixing plate 200, the second fixing plate 201, the third fixing plate 303 and the fourth fixing plate 304 are all fixedly welded to one side of the control cabinet 100.
[0027] In this embodiment, preferably, the unwinding mechanism includes a positive electrode unwinding roller 400, a diaphragm unwinding roller 401, and a negative electrode unwinding roller 402, with one end of each of the positive electrode unwinding roller 400, the diaphragm unwinding roller 401, and the negative electrode unwinding roller 402 fixedly installed on the side wall of the control cabinet 100.
[0028] In this embodiment, preferably, two limiting sleeves 302 are provided and arranged symmetrically with respect to the midpoint of the coil needle 300, and two limiting rods 206 are provided and arranged symmetrically with respect to the connecting post 204.
[0029] In this embodiment of a lithium battery winding machine with neatly shaped sides, the positive electrode sheet, separator, and negative electrode sheet rolls are first installed onto the unwinding rollers via the unwinding mechanism. Then, the operator manually pulls each roll through the top of the guide roller 208 of the pressing mechanism. Simultaneously, the operator manually pulls the lifting plate 203 upwards, causing the pressing plate 205 to move upwards synchronously. At this time, since the two ends of the spring 207 are fixed to the strip plate 202 and the lifting plate 203 respectively, ... The strip plate 202 is fixedly installed between the first fixed plate 200 and the second fixed plate 201. Therefore, the spring 207 is stretched accordingly. When the roll material passes through the top of the guide roller 208, the lifting plate 203 is released, and the spring 207 contracts, causing the pressing plate 205 to press against the top of the guide roller 208, achieving a pressing effect on the roll material. This results in multiple rolls of material tightly overlapping, and due to the squeezing action, it also provides tension for the winding of the roll material, preventing wrinkles during winding and improving winding quality. Furthermore, this pressing mechanism is applicable to roll materials of different thicknesses, making it widely applicable. After the worker passes the roll material through the top of the guide roller 208, it is pulled to the outside of the winding needle 300. Depending on the width of the roll material, the limiting sleeves 302 connected to the outer threads at both ends of the winding needle 300 can be rotated to make the spacing between the two limiting sleeves 302 adapt to the width of the corresponding roll material. The setting of the limiting sleeves 302 plays a certain role in preventing deviation during the winding operation of the roll material, further ensuring the winding effect. In addition, the limiting function of the winding needle 300 can be flexibly adjusted according to the roll material of different widths, making it widely applicable and more practical.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
